Description

HYDROELECTRIC POWER PLANT PRODUCING ENERGY USING STANDING

WATER IN A LOOP

TECHNICAL FIELD The invention relates to hydroelectric power plants producing electricity using drop (height) of water.

The invention particularly relates to hydroelectric power plants producing electricity by giving drop to standing water.

STATE OF ART With the increase of technological developments along with rapid increase of world population, necessity for all forms of energy including electricity and fuel for realization of manufacturing processes, transport, shipping, lighting and heating is increasing day by day. Hydroelectric power plants and fossil fuel sources has been satisfying to this demand for years. However, these sources have become insufficient in satisfying energy demands of the increasing population. Hydroelectric power plants are incapable of operating with full capacity due to dry years. Moreover, the water utilized in hydroelectric power plants is generally from fresh waters, and used as drinking water and for irrigation water in agriculture. This results in negative effects for both drinking water sources and for agriculture. In addition, it is known that fossil fuel sources are limited and have negative effect on environment. Indeed, when fossil fuels are burned, it gives off greenhouse gasses such as carbondioxide, methane etc. to the atmosphere, thereby causing global warming. Use of nuclear energy is limited due to dangers such as radiation leakage and explosion. Considering the situations mentioned above, solar and wind energies stand out. Nevertheless, these are not reasonable for investment as they have high installation cost and do not have common usage.

Consequently, there are limitations relating to source usage in energy production, or energy production is limited as it is affected from natural conditions. These limitations cause negative effects in satisfying the increasing energy demand. Considering these situations, systems are required that are not to be restricted in terms of source usage.

There are national and international applications in patent database relating to this situation. Within these applications, there are those making electricity production using the power of waves occurring in seas and oceans as well as electricity producing systems enabling rotational force by transferring awash objects in a loop to buckets. Also, in some hydroelectric power plants in some countries, water is used in energy production in more expensive hours, then pushed up with pumps in cheaper hours. Among these applications, a foreign application coded CN101876288 is a system designed using lifting force applied on awash objects of water rather than use of water in a loop. Similarly, an application coded US2014196450 related to a generator producing energy with entering of awash steel objects into open buckets attached onto a belt in a loop. An application coded US2015013325 is a device producing energy from energy of waves. Said device is a device optimizing the energy of waves with a platform present underwater and buoys connected to said platform with piston pump and being compatible with said platform. Wave movement drives the pump to push pressurized water to hydraulic turbine. Thusly, the turbine rotates thereby rotating the generator. The produced electric energy is transferred with electricity cables embedded under water in coast. Said invention is beneficial at times when seas or oceans are rough while it does not function at times when sea is still standing. This disturbs sustainability of the system, and cannot enable the continuity in production. Similarly, an application coded TR200504542 is a system producing electricity from wave energy. In said system, there is a buoy over the water, and a counter weight thereunder. There is also a moving arms moving with the movement of the counter weight. This moving arm is connected to a suction and force pump, and pushes the water up with downward-upward movement of waves. The pressurized water is collected in buckets arranged around two pulleys in parallel with one under the other elliptically. The buckets rotate the system by moving in accordance with the weight of the water. With the rotation of a shaft connected to the system, electricity production is enabled by rotation of generator as well. As this system is also dependent on sea's being rough, sustainability of production cannot be enabled as it does not operate at times when sea is standing. A national application coded TR201210306 is a system producing electricity energy without providing first energy from standing water. Said system consists of a shuttle secured with at least one shuttle connecting piece enabling the rise of the standing water within the pool by circulation, being in a lower density than the density of water and at least one orbit in which said shuttle continuously flows via rising water. Sealing members being present in the shuttle structure enabling the rise of water in the system get worn by time and lose the feature of sealing. This causes the system to be taken into maintenance periodically, and the increase of operating costs. An application coded TR201403253 uses moving water, and reservoir, power conduits and turbines in known HPPs are removed, and the generator is rotated by a mechanism rotating with the weight of the water. Consequently, presence of the problems above and the inability to find a present solution necessitated an improvement in the related art.

OBJECT OF THE INVENTION

The invention aims solving the problems mentioned above, eliminating all disadvantages and bringing additional advantages to the structure. An object of the invention is to enable sustainability in production of electricity energy by eliminating the dependence on a source. In order to realize this object, standing water is prepared by transporting to a production pool with a transport mechanism, thereby giving height (drop) to water.

Another object of the invention is to enable the use of fresh waters accumulated in dams for drinking water and irrigation purposes in agriculture. In order to realize this object, the water is used in a closed loop, thereby decreasing the dependence on a source.

Structural and characteristic features, working principles and provided advantages of the invention will be obvious thanks to the following drawings and the detailed description written with reference to these drawings. Hence, evaluation should be performed considering these drawings and the detailed description.

DETAILED DESCRIPTION OF THE INVENTION

The power plant (1 ) is a structure consisting of the water intake pool (10), the transport mechanism (100), the transfer pool (20), the discharge pool (30), the production pool (40), the pressure pipe (50) and the turbine (60). The water intake pool (10) has a width of 1 .5 m, a height of 2.5 m and a depth of 1 .5 m. It has a water intake capacity of 5625 kg according to these dimensions. The water inside the water intake pool (10) is transported into the transfer pool (20) with the transport mechanism (100). The transport mechanism (100) consists of the drive mechanism (120) and the transport buckets (1 1 1 ). The drive mechanism (120) consists of the drive center (121 ), the reducer (122), the transmitter (123), the drive gear (124) and the guiding gear (125). The drive mechanism (120) enables the transfer of the transport buckets (1 1 1 ) arranged around the transmitter (123) from the water intake pool (10) to the transfer pool (20) in a loop by driving the drive center (121 ). The transmitter (123) is a caterpillar track, and wraps the drive gear (124) and the guiding gear (125) along the distance between the water intake pool (10) and the transfer pool (20). The drive center (121 ) is an engine of 50 kw, and connected to the reducer (122) and the shaft (126). Said shaft (126) forms a bearing with the bearing members (127) from two points. Said shaft (126) is connected to the drive gear (124) of the drive mechanism (120) on the one end, and to the drive gear (124) of the overflow mechanism (32) on the other end. The transport buckets (1 1 1 ) are positioned around said transmitter (123) with a certain distance therebetween. There is also a reducer (122) transmitting the speed and power from the drive center (121 ) to the gears by adjusting these.

There are two types of buckets inside the power plant (1 ), one of the transport mechanisms (100), the other of the overflow mechanism (32); one has open orifice and closed bottom, where said bucket is the transport bucket (1 1 1 ), thereby feeding water into the water pool (20). The other has closed orifice and open bottom, where said bucket is the overflow bucket (34), thereby enabling water flow of a fixed flow rate to the production pool (40) by overflowing the water in the discharge pool (30). Said transport bucket (1 1 1 ) and the overflow bucket (34) have the same dimensions, in that it has a width of 0.8 m, a length of 0.8 m square and a depth of 1 .6 m. Each bucket has a water intake capacity of 1024 kg according to these dimensions.

The transfer pool (20) is the pool in which the water coming from the transport mechanism (100) is collected. Said transfer pool (20) has a width of 1 .5 m, a length of 1 .5 m and a depth of 2 m. It has a water intake capacity of 4500 kg according to these dimensions. The water collected in the transfer pool (20) is transferred into the discharge pool (30) with the transfer channel (21 ). The load pulled by the reducer (122) is diminished thanks to the pressure applied by the overflow buckets (34) in the discharge pool (30) by the combination of the flow rate of the transferred water and the rotational force of the reducer (122). As the transfer channel (21 ) is higher than the discharge pool (30), flow direction of the water is from the production pool (40).

The discharge pool (30) is the pool in which the water coming from the transfer pool (20) is collected. The discharge pool (30) is connected to the production pool (40) with the overflow drain (31 ). Said discharge pool (30) has a width of 2.5 m, a length of 2 m and a depth of 30 m. The discharge pool (30) has a water intake capacity of 150 tons according to these dimensions. The discharge pool (30) is separated into two with the division panel (33). The water inside the discharge pool (30) is fed into the production pool (40) with a fixed flow rate with the overflow mechanism (32). The overflow mechanism (32) is similar to the transport mechanism (100), only bucket types and functions are different. The division panel (33) separated the overflow buckets (34) of the overflow mechanism (32) into two groups by intervening the transmitter (123). The overflow buckets (34) in the section with the bottom facing upwards are submerged into the water inside the discharge pool (30), and make a water feeding of a fixed flow rate from the overflow drain (31 ) to the production pool (40) by overflowing the water each as much as their individual volumes. The overflow buckets (34) serving for overflow are on the side of the overflow drain (31 ). Sharp edges of the overflow buckets (34) are turned to downward while sharp edges are turned to upward. Thusly, it discharges the water from overflow pool and the loop continues as such.

The production pool (40) is the pool feeding water into the turbine (60) via the pressure pipe (50). It is enabled that the water is directed into the pressure pipe (50) with a certain pressure and flow rate by providing slope to the bottom of the production pool (40). The production pool (40) has a width of 5 m, a length of 5 m and a depth of 30 m. It has a water intake capacity of 750 tons according to these dimensions. The water hitting into the turbine (60) by means of the pressure pipe (50) from the production pool (40) is transferred into the water intake pool (10) with the draining channel (41 ).

Working principle of the power plant (1 ) is such that both the transport mechanism (100) and the overflow mechanism (32) starts to rotate with the rotation of the reducer (122) connected to the drive center (121 ) with the initial drive from the drive center (121 ). With the rotation of the drive gears (124) connected to the transport mechanism (100), the guiding gear (125) also rotates, also rotating the transmitter (123). With the rotation of the transmitter (123), the transport buckets (1 1 1 ) around said transmitter (123) are submerged into the water intake pool (10) and start to be filled with the water. Each transport bucket (1 1 1 ) having filled with the water discharges the water to the transfer pool (20) sequentially by covering the distance between the water intake pool (10) and the transfer pool (20). The water discharged into the transfer pool (20) is transferred to the discharge pool

(30) with the transfer channel (21 ). The water collected inside the discharge pool (30) is fed into the production pool (40) in a fixed flow rate from the overflow drain

(31 ) with submerging of overflow buckets (34) connected to the overflow mechanism (32) into the water in a pool separated by the division panel (33). The water inside the production pool (40) hits its potential energy provided with height to the turbine (60) with the pressure pipe (50) as pressurized and in a fixed flow rate, thereby obtaining a mechanical work with the turbine (60). This mechanical work is converted into electric energy with generator. The electric energy that is produced is 290 kw. The water outgoing the turbine (60) is transferred into the draining channel (41 ) water intake pool (10). During this production, 3600 tons of water per hour is circulated in a loop.
