Abstract

A water system includes a reciprocating pump (6) operated by pedal power. The pumpstand (14) includes a housing in which a foot pedal (18) and a drive shaft (62) rotate. An eccentric pin (68), rotating with the drive shaft, moves a connecting rod (66), which in turn causes a pushrod (71) to oscillate vertically. The pushrod (71) extends into a pressure-tight chamber formed above the rising main (8) (wellpipe). A pumprod (44) connected to the pushrod extends to move a conventional plunger (43) through vertical oscillations. A flywheel (76) is attached to the drive shaft, and a counterweight (82) is mounted on the flywheel diametrically opposite the eccentric pin. The radial distance from the drive shaft to the counterweight can be adjusted. A discharge pipe (24) extends from the pressure-tight chamber to an elevated or pressurized storage tank (27). A distribution pipe (28) from the storage tank feeds water to a number of distribution points (32), such as faucets in houses.

Description

] Sr5WATER SYSTEM WITH AN ALTERNATIVE PUMP POWERED BY THE ENERGY OR A PEDAL FIELD OF THE INVENTION This invention relates to water distribution systems, and more particularly cor. water distribution systems energized by human force.

BACKGROUND OF THE INVENTION The history of positive displacement of alternative bombs dates back to 275 BC in ancient Rome. In the sixteenth century, large force and lift pumps, driven by water wheels, became the main method for pumping piped water in Europe. Later, in the year 1987, the World Bank estimated that, worldwide, 1.8 billion people would need to improve water supply, and that wells equipped with hand pumps could be an appropriate choice to meet the needs of this number of people Most alternative hand pumps normally used in developing countries have their origins in developed designs REF .: 31780 at the end of the 19th century and at the beginning of the 20th century in the United States and in Europe. In the United States, about 42 million hand pumps were made until 1920, when electric pumps began to replace them. While the basic design of the alternative hand pump has not changed much in this century, its typical use has changed quite a bit. At the beginning of this century, in the United States and Europe, the large market for pumps was for small pumps in the backyard of the house used for ten to thirty minutes per day by farmers or individual families. Currently, in a developing country, a single pump can supply more than 500 villagers and can be in continuous operation for ten or more hours per day. A manually operated pump is needed in a developing country which can be easily operated by a person for relatively long periods of time and which means high volumes of water with as little effort as possible. Because of the high usage requirements, and because the pump must be operated as a practical device away from cities that have personnel and maintenance facilities, the pump must be reliable and easy to repair.

A hand pump connected to a typical well is driven by pressing the end of a lever down and by either pulling up or allowing it to rise due to the weight of the well. The work of ascending the water occurs while the lever is pressed down. The simple type of an alternative pump is the suction pump, which draws water from shallow wells by creating a partial vacuum in a suction tube. All moving parts, including a mobile arm, moved by the lever and a suction check valve, are located above the ground; only the suction tube extends down into the well. As the lever is pushed down, the movable arm moves up, raising the water to the top to be discharged through a trough, and extracting the water from bottom to top through an open suction check valve. As the lever moves up, the movable arm moves downward, by lowering the water, creating a pressure which opens a valve in the movable arm while closing the suction check valve. Two disadvantages of this type of pump are, first, it must be charged with water before it can be used, and second, the main suction, depends on the atmospheric pressure to raise the water, limiting the utility of the device for wells having depths of less than approximately seven meters. In the alternative pumps for deep wells, the cylinder is immersed in the well below the water level, being pushed up and down by a rod that extends under the well tube. This arrangement is suitable for wells with a depth of 45 meters or more, with the limit of operation that depends on the effort that the users achieve to apply to progressively decrease the water in greater depths. As the depth of the well increases, more work will be required to raise the water column in the well tube, along with the steel rod that extends under the tubing of the well to the cylinder. A problem with most alternative pumps is caused by the fact that the lever used to operate the pump, as it provides an extremely simple mechanism, does not make good use particularly of the ability of the human body to perform mechanical work. The downward force that a person can provide to raise water in this way is limited by its own weight, since the lever first uses the muscles that move the arms and upper body, while in a normal person moves the muscles of the arms. legs that are stronger and able to be used for longer periods of time. Another problem with most alternative pumps originates from the fact that the work of raising the water and the pump mechanism occurs only while the lever is pushed down. For example, a conventional alternative pump requires a force of approximately 20 kg while the lever is pushed down, while a force around only 4 kg is required to move the lever back up. Thus, unequal requirements are attributed to the user to supply energy to the pumping process. A number of configurations for pumps have been developed to overcome several of these disadvantages so that they apply to the driving forces. For example, a foot pedal type pedal, driven together with a pair of steering wheels, has been applied to a double piston pump, Model SB-115, manufactured by Water Conservancy Bureau of Shandong Province, China. The Climax manual pump, manufactured by Wildon Engineering of Worcestor, United Kingdom, and the Volanta hand pump, manufactured by Jensen Venneboer BV, The Netherlands, both pumps in which an alternative movement is developed using a connecting rod driven by a rotating crank mounted on a shaft together with a steering wheel . An eccentric rod extends from the steering wheel to be used as a manual crank. The Climax hand pump also uses a counterweight to balance the lifting force applied through the crank. Thus, the pump in Shandong Province, China, has the advantage of using the strongest muscles that move the legs, while the wheels of the three types of pumps help to expand the requirements of force on the cycles of operation through storage. of energy. The counterweight of the Climax hand pump provides additional assistance in balancing the torque requirements of the hand crank. However, the posture and leg movements in the bicycle seat, both of which are known to be comfortable and practical to provide mechanical work over a long period, are not used for the entry of force into these pumps. A bicycle-type pedaling and seating arrangement is used to power centrifugal pumps, Model 1-1 / 2-JB, manufactured by Anyue County Farm Machinery Plant, Sichuan Province, China, and the Jinshan-402B Model, produced by Zhenjiang Sprinkler Plant, Jiangsu Province, China. It is necessary that a pump incorporates the posture and pedal configuration of a bicycle for the input force with the simplicity, reliability and flexibility of the alternative pump application. The force required to lift the rod and water mechanism of an alternative pump varies with the depth of the well. While the counterweight of the Climax pump attempts to balance this force, it can not move to compensate for differences in the depth of the well from one installation to another. Likewise, inside an installation, it is not unusual to increase the depth of a well, compensating it for a bank of water fall. Therefore, it is necessary to have a way to vary the position of the counterweight to compensate for differences in strength resulting primarily from differences in the depth of the well. The qualities of leaflets and counterweight are also discussed by Arlosoroff, and contributors, Community Water Supply, The Handpump Option, (The World Bank, Washington, D.C., 1987) indicating that a properly counterbalanced flywheel in a pumping application can be operated quickly, particularly when operated by two people. These editors further indicate that the counterweights should at least balance the thrust of the pump rod and the movable arm. A conventional hand pump or other alternative pump includes a chute that extends outward and slightly descends from a point 1.50 m (5 feet) above the ground level, below the point where "the pump is operated. , and a rod extend upwards through an opening, being attached to a lever or, in the case of the Climax and Volanta pumps, to a crank driven by means of a connecting rod. The pump is not sealed, the water can not rise above the pump chute, On the other hand, electrically driven water pumping systems in developed countries are normally sealed in such a way that considerable pressure can develop above the pump. In a common hydraulic system, this pressure is used either to raise the water level to a high storage level or to inject the water into an adjusted tank of pressure at the ground level. stored in this way is dispensed consecutively under pressure through a pipe system, which can be used in a particular rural house or in a whole city. In developing countries, this type of water distribution is also desirable, although it is generally not achieved in rural areas. A piped system, which supplies water in private homes, provides important advantages, both from a convenience and sanitation point of view. Considering the changes described above in the models of use of * manually operated pumps, by which, a pump can supply water to 500 villagers, where a water supply system including an alternative pump which can be operated on is particularly necessary. means of a manual crank or a pedal system and which can pump water under pressure in an elevated or pressurized tank.

DESCRIPTION OF THE PREVIOUS TECHNIQUE US Patent 1,358,213 to Joerns discloses an alternative gear drive pump having a superior seal, through which a pair of alternative rods operate, and a pressure chamber is formed with a partition wall and a drain passage, allowing the discharge of water near the surface of the support. This feature allows the pump to operate under considerable pressure for various purposes, discharging a continuous stream of water under pressure from the pump. While the Joerns pump shows improvements in the mechanism used to produce an alternative movement, the gear mechanism is still driven by a handle, or by an unspecified external power source that operates a pulley. It is needed, for the affective application of the Joerns device for the current needs of the rural areas of a country is development, the other components of a complete hydraulic system to supply water to a number of faucets, together with the means that allow the device operated by the most efficient pedaling process.

SUMMARY OF THE INVENTION According to another aspect of the invention, a fixed pump is provided for driving a pump rod in vertical reciprocating motion. The fixed pump includes a housing, a drive shaft, a drive mechanism, a counterweight, a foot pedal and a chain. The drive shaft is mounted to rotate inside the housing with a drive sprocket and a flywheel attached to the drive shaft. The transmission mechanism converts the movement of the motor shaft into a reciprocating vertical movement of the pump rod. The counterweight is raised as the pump rod is lowered and the counterweight is lowered as the pump rod rises. The foot pedal is also mounted to rotate inside the housing, with a drive sprocket unit to the foot pedal. The chain extends between the driving sprocket and the drive sprocket, the engagement of these sprockets causes the rotation of the driving sprocket and the rotation of the drive sprocket. In accordance with another aspect of the invention, a water supply system is provided to deliver the groundwater to a number of distribution points. The system includes a rising media (a tube that extends under a well), a vertical oscillating structure, a foot valve, a pressure adjustment chamber, a fixed pump housing, a transmission mechanism, a sealing mechanism, a discharge tube, a distribution tube, and a pressurization mechanism. The ascending medium extends down into the groundwater in groundwater. The vertically oscillating structure includes a pump rod that slides in the ascending medium and a movable arm that slides in the ascending medium and the groundwater. The movable arm includes a movable arm valve that opens as the movable arm moves downward through the groundwater and closes as the movable arm moves upward through the groundwater. The foot valve controls a flow of water from a lower portion of the ascending medium down the movable arm, opening while the water flows in this lower portion and closing to prevent a flow of water from this lower portion. The pressure adjustment chamber is on the surface of the rising medium. The housing of the fixed pump extends upwards from the pressure adjustment chamber. A motor shaft, on which a flywheel and a counterweight are mounted, this assembly rotates in the housing of the fixed pump. A drive chain extends between the foot pedal and the drive shaft causing the motor shaft to rotate while the foot pedal rotates. The transmission mechanism converts the rotation of the motor shaft into a vertical oscillation of the vertically oscillating structure. The sealing mechanism prevents the loss of water around a part of the vertically oscillating structure that extends through the pressure adjustment chamber. The discharge tube extends from the pressure adjustment chamber to a storage tank, the distribution pipe extends from the storage tank to the distribution points. The pressurization mechanism causes a flow of water through the distribution pipe to the distribution points.

DETAILED DESCRIPTION Figure 1 is a perspective view of various portions of a water supply system for a rural community constructed in accordance with the present invention. A pump station 6 includes a rising medium 8 (well tube) that descends below ground to a level at which a cylinder 10, within the rising medium 8, is immersed in the well water. Generally, and as a more detailed explanation of Figure 2, inside the cylinder 10, a movable arm is raised and lowered in an alternating motion by means of a pump rod, which, in turn, is moved by means of a mechanism within a fixed pump 14. The energy required to operate the mechanism within the fixed pump 14, is obtained as a person pedals a foot pedal 18, while sitting in a seat 20 in a posture similar to that of a cyclist. The seat 20 is attached to the fixed pump 14 by means of the frame rails 21. Both the fixed pump 14 and the seat 20 can be mounted on an optional base of concrete foundation 22.

A discharge tube 24, connected in a pressure adjustment chamber 25 near the base 26 of the fixed pump 14, which extends upwards to a point, up to 8 meters above the surface of the earth to fill a tank of elevated water 27. A distribution tube 28 extends down the bottom of the water tank 27 and out to provide water to a number of buildings 30 with keys 32 and other water attachments (not shown). The distribution pipe 28 can be part of a network including other distribution pipes 33. A first tap 34, a fixed pump 14, and a second tap 36, in the distribution pipe 28, are provided for use also, in the joining a hose (not shown) or filling water containers (also not shown). If water is needed quickly when the tank 27 is empty, it can be obtained from the first tap 34 while the fixed pump 14 is operated with foot pedals 18. Alternatively, if the tank 27 is not empty, the water can be obtained from the second tap 36 , as well as the keys 32. Figure 2 is a vertical cross-section of the mechanism of the cylinder 10, which is a conventional design, in the bottom of the ascending medium 8. The water enters the cylinder 10 through a tube of suction 40, preferably ascending to the groundwater level at or slightly above the surface of the cylinder 10. A foot valve 42 operates while a check valve operates with the water flow in the cylinder 10, while on the other hand side closes. Within the cylinder 10, the movable arm 43 moves up and down in reciprocating motion by the pump rod 44, which engages in a hook-shaped portion 45 of an adaptation of the movable arm 46. While a movable arm 43 moves down, the movable arm valve 48 opens to allow a flow of water through the movable arm 44 along an adjusting valve 50. In this way, the movable arm 43 moves down easily, while the foot valve 42 closes to prevent outflow of water flow. While the movable arm 43 moves upwards, the valve of the movable arm 48 is also operated, as a check valve closes, so that the water above the movable arm 43 ascends. The resulting suction causes the foot valve to open, allowing more water to flow into the cylinder 10. Referring now to Figures 3 and 4, which show the views of the mechanisms of the fixed pump 14, located in the surface of the rising medium 8. More specifically, Figure 3 shows a vertical cross sectional view and Figure 4 shows a horizontal cross sectional view taken through the lines of section IV-IV in Figure 3. In Figure 3 various guards or housing sections 53, which are provided particularly to prevent personal damage by moving parts, shown in the cross section to disclose the mechanisms installed therein. "As the foot pedal 18, rotatably mounted on a pair of supports 54, is operated, a drive sprocket 56, mounted to return with the foot pedal 18, drives a chain 58, which in turn causes the rotation of the driving sprocket 60. The sprocket 60 is mounted firmly on a motor shaft 62, which is rotatably mounted within the housing 64 by means of a pair of supports 65. A connecting rod 66 rotatably mounted to extend between a eccentric pin 68 extending from the drive sprocket 60 and an adapter 70 to the surface of the push rod 71 connected to the pump rod 44. The push rod 71 is mounted vertically slidable within the support structure 72 a intermediate gear 74 which is also rotatably mounted within the housing 64, can be adjusted in position to maintain an appropriate tension in the chain 58. A flywheel 76 is also connected in turn with the shaft 62, with a radius 78 retaining a radial groove 80, which extends to the diametrically opposite eccentric pin 62. A counterweight 82 is held at a certain point on the flywheel 76 by means of a pair of screws 84 which extend through the groove 80. for coupling a retaining plate 88. A steering wheel housing 90 can be included to protect the other rotating steering wheel 76. With this arrangement, the counterweight 82 moves to its low position while a pump rod 44 moves to its highest position. , and vice versa. In this manner, the counterweight 82 is used to counterbalance the combined weight of the pump rod 44, the movable arm 43 (shown in Figure 2) and the water within the rising medium 8 and within the lifting portion of the Discharge 24. Using the screws 84, the position of the counterweight 82 can be adjusted along the length of the slot 80. Since the combined weight for counterbalance varies too much with the depth of the well and the height of the discharge tube 24, this setting is used to customize the fixed pump 14 while it is installed in an individual well. After the initial installation process, the position of the counterweight 82 can be changed to accommodate changes to the system, such as variations in the weight of the discharge tube 24, changes in the depth of the well, or in equal preferences of the user. In providing an adjustment, the fixed pump 14 provides an important advantage over the Climax hand pump, described above, which has a counterbalance mounted in a fixed position. During the operation of the water supply system, the water is carried upstream through an ascending means 8 in a pressure adjusting chamber 25 between a lower cover plate 91., secured on top of a base 92 with a number of screws 94, and an upper cover plate 96, to which the fixed pump housing 64 in turn is secured with screws 98. The first tap 34 and the discharge tube 24 extend from the pressure adjusting chamber 25. The pressure is maintained within the chamber 25 by the use of a slidable seal 102, which prevents the filtration of water in a load structure 72. The conventional valve mechanism within of the tap 34, is operated by a handle 103, another part of the sealing system of the chamber 25 forms when this tap 34 is closed. In this way, the fixed pump 14 is provided with an important advantage over the reciprocating movement produced from conventional fixed pumps, in which the conventional fixed pumps in this manner do not include a plate extending through the surface of the well, or no method to seal around a rod descends in the ascending medium. Therefore, a conventional fixed pump can only provide water through a spout extending to the lower level of the first tap 34. On the other hand, the fixed pump 14 can pump water under pressure in the elevated tank 27, forming part of the a water supply system providing water to individual homes or other remote locations. The use of a storage tank in this way also allows the extraction of water for use to occur at a different time than the pumping of the water. Referring to Figures 2 and 3, while providing a pressure adjustment chamber 25, the complete fixed pump 14 can be removed by loosening the screws 98, and the pressure adjusting chamber 25 can be removed from the wheel by loosening the screws 94. Discharge tube 24 is preferably connected to chamber 25 by removable, conventional means to facilitate this process. In this way, the access is provided to allow the movable arm 43 to ascend out of the well, for maintenance, by means of the pump rod 44. A foot valve structure 104 is adapted with a circuit 105, in this way to can also ascend out of the well. Referring now to Figure 5, a cross-sectional view of a pressure adjustment water tank 106 is shown. Tank 106 may be used in place of the elevated water tank 27, shown in Figure 1. As the water is pumped in the adjusting pressure tank 106 from the discharge pipe 24, the air retained in the tank section 108 above the water level is compressed, providing pressure to force the water through the distribution pipe 28 which extends from the tank 106 as the taps 32 or other valves are opened along the distribution pipe 28. The use of air pressure in this manner makes it unnecessary to put the tank 106 in an elevated structure.Referring now to Figure 6, a housing 110 is shown to control the pumping station 6 and a water storage unit.Where the elements described above are shown in Figure 6, the numbers are used as a reference. pre-charged 112 is included within the housing 110 and may be similar to the pressure adjustment tank 106 shown in Figure 5 or the tank 112 may preferably be a pre-filled water tank of a commercially available type from, for example, Dayton Electric Mfg CO ., from Chicago, Illinois. Pre-filled water tanks typically consist of an elastic bag such as a butyl rubber bag, contained in a metal housing. The bag expands when the water is added through the discharge tube 24 and presents a force of pressure on the water due to the elasticity of the same. As the water leaves the bag through the dispensing tube 28, the bag contracts while holding the water under pressure until the bag almost empties. The pipe inside the housing 10 (not shown) connects the mechanisms of the pumping station 6, shown in Figures 2-4, to tank 112 in a conventional manner. This piping may include a waste trap or filter (not shown) for the prevention of sand or small rocks entering the pre-charged tank 112. Similarly, the outlet connected to the internal piping, of the pre-charged tank 112 for a plurality of taps 34 located on the housing 110, as well as the distribution tube 28. In addition, a pressure indicator 114 can be added to provide operators with information of the available pressure of the pre-charged tank 112 that releases the water. A water treatment system 116 can be added between the performance of the pre-charged tank 112 and the distribution pipe 28 by adding chemical properties for a community hydraulic system. Alternatively, the water treatment system 116 may be placed within the housing 110 between the pumping station 6 and the pre-charged tank 112 in conjunction with the waste trap. Because of the inclusion of the flywheel 76 the effort necessary to maintain the continuous operation of the pumping station 6 is not greater, particularly when the pre-charged tank 112 is not full. In fact, a small electric motor 118 can be fixed to the housing of the flywheel 90 to provide a rotary force to the flywheel 76. The motor 118 can be energized by a small solar panel 120 located on the surface of the housing 110, since then the conventional electrical energy It is not generally available in the areas where the invention will be used. It should be noted that the engine 118 only maintains the rotation of the steering wheel 76. Manual use of the foot pedals 18 will still be required to initiate the pumping action of the pumping station 6. While the invention has been described in its form or preferred embodiment with some degree of particularity, it will be understood that this description has been provided only by way of example and that changes of the numbers in the details of construction, manufacture and use, including the combination and arrangement of parts, can be made without departing from the spirit and scope of the invention.
