Description

HAND TYPE WATER PUMP

The present invention relates to a manual water pump, and more particularly, to a water pump which is capable of reducing installation space required for installing a water pump, capable of a positive water supply even when the water level of the groundwater is deep, The present invention relates to a manual water pump capable of discharging ground water to the ground at the same time as a water pump is operated, and can easily replace deformed or damaged parts for a long time.

Generally, a water pump is a device for pumping ground water to the ground. In the water pump, there are a manual water pump for pumping ground water by a worker and an automatic water pump for pumping ground water by using electric energy such as a motor pump.

Although the manual water pump is relatively more advantageous than the automatic water pump in terms of installation and maintenance costs, it has a limitation in applying the workforce to the operator due to the structural characteristics of raising the ground water to the manual water pump. In the places where the groundwater level of the ground is low, There is a problem in that it is difficult to install a water pump and an automatic water pump having a relatively high installation and maintenance cost is installed or a relatively expensive water motor is installed.

In the conventional manual water pump, the groundwater is pumped up from the ground to the manual water pump through the ground water pumping pipe connected to the manual water pump and discharged to the ground through the manual water pump. According to this structure, There is a problem in that components such as the piston are frequently exchanged due to the generation of wear in the piston and the like constituting the manual water pump.

The conventional pump well type distributor of Japanese Unexamined Utility Model Application Laid-Open No. 5-52269 pushes the water indirectly through the air by the pressure applied to the water pump. Therefore, by the method of compressing the air to form the water pressure, It can not be applied to the aquifer because air can not be compressed in an open space such as an aquifer.

In addition, the manual pump of Japanese Laid-Open Patent Application No. 2005-315230 can replace a plurality of valves collectively, thereby making it possible to reduce the time required for compacting and inspecting, but it is difficult to raise groundwater deep in the underground. In the untreated state, water can be drawn up by the water pressure only when the priming water is put in the priming water, and it is difficult to obtain priming from the outside.

In order to solve the above-mentioned problems, a manual water pump has been developed. In the conventional manual water pump, a bending pipe member, which is bent in such a manner that the body is positioned in the ground, And a pressure member for applying pressure to the bending pipe member, the bending pipe member includes an inlet-side check valve for preventing back flow of the groundwater introduced into the 'U' -type, and an outlet- An inlet side check valve disposed at a lower portion of the bending pipe member and positioned on the ground surface and formed in a cap shape and having a flange portion formed on an outer side thereof; The outlet through which the ground water flows out is exposed to the ground, the pressure member communicates with the bent pipe member, and is installed in the well A piston protruding from the piston to the inside of the bent tube member; and a sealing member surrounding the outer periphery of the piston to seal the inside wall of the cylinder, .

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Registration No. 10-1675894 (published on Dec. 01, 2016, entitled: Manual type water pump).

The conventional manual water pump has a problem in that it is difficult to reduce the time and cost required for installation of the water pump because the installation space required for installing the water pump can not be reduced because the bending pipe is installed and the ground water is pumped to the ground.

In addition, the manual water pump according to the related art has a problem that the entire water pump needs to be replaced in order to replace the piston when the piston which reciprocates in the cylinder installed in the water pump and is operated for pumping is deformed or damaged for a long time.

Therefore, there is a need for improvement.

The present invention can reduce the installation space required for the installation of a water pump, and it is possible to pump water even if the water level of the groundwater is deep, and the priming operation is not required at the beginning of the operation of the water pump. And it is an object of the present invention to provide a manual water pump which can easily replace a deformed or broken part for a long time.

The present invention relates to a pumping system comprising: a pumped water main body erected on a ground surface and provided with a discharge port through which groundwater is discharged; A connection body connected to the amniotic water main body and embedded in the ground and having a suction port through which groundwater flows; A partition panel disposed between a lower end of the amniotic fluid body and an upper end of the connection body to provide a boundary between the amniotic fluid body and the connection body; A pumping unit that pressurizes the groundwater flowing through the inlet port to the discharge port side while varying the pressure inside the cylinder formed between the stepped portion of the connection body and the partition wall panel; A leakage prevention unit for preventing groundwater introduced into the cylinder through the suction port by the operation of the pumping unit from being discharged to the outside of the connection body or the connection body; An operation part installed to protrude outside the amniotic water main body so as to drive the pumping part, and to transmit the operation force of the user as a driving force of the pumping part; And a detachable connection part detachably connecting the pumping body and the connection body.

Therefore, when the manual water pump is installed, the connection body 14 is buried in the ground so that the suction port 16 is contained in the flow path of the ground water flowing along the ground, and the partition wall panel 36 is welded to the lower end of the pumping body 10 And the operating pipe 32 is slidably installed along the hole formed in the central portion of the partition wall panel 36. [

Thereafter, the piston 34 is provided at the lower end of the operating pipe 32, and the amniotic water main body 10 and the connecting main body 14 are coupled by the operation of the attaching / .

As described above, since the manual water pump according to the present embodiment is constructed such that the straight pipe members are connected to each other and installed in the ground, a separate bending pipe is not required, so that the installation space required for the construction of the water pump can be reduced, Time and cost can be saved.

The pumping section 30 of the present embodiment includes a working pipe 32 inserted from the amphibious main body 10 and slidably inserted into the connecting main body 14 through the partition wall member, And a piston 34 sliding along the inside of the cylinder formed between the partition member and the step 18 of the connecting body 14 to cause a pressure change inside the cylinder.

Accordingly, when the operation pipe 32 is lowered by the operation of the operation part 80, the piston 34 pressurizes the ground water desiccated in the cylinder, so that the ground water flows through the hole formed at the lower end of the operation pipe 32, The ground water rising along the operation pipe 32 is discharged to the inside of the amphibious main body 10 through the discharge hole portion 32a and the water surface of the ground water which is to be discharged into the amphibious main body 10 rises The water is discharged to the outside of the amniotic fluid body 10 through the discharge port 12. [

At this time, the groundwater that is dewatered to the pumping water main body 10 and the groundwater that is dewatered to the connection body 14 are not lowered to the ground again by the operation of the loss preventing portion 70, It is possible to perform the pumping operation of the ground water with the inner pressure variable.

The loss prevention portion 70 of the present embodiment includes a first check valve 72 provided at the suction port 16 and a second check valve 74 provided at the operation pipe 32. [

Therefore, when the user operates the operation part 80 and the operation pipe 32 and the piston 34 are raised, the pressure inside the cylinder is lowered, so that the first check valve 72 is opened and groundwater in the ground is drawn into the suction port 16 The first check valve 72 is closed so that the pressure inside the cylinder is increased so that the operating pipe 32 and the piston 34 are closed. The second check valve 74 is opened.

The ground water raised along the operation pipe 32 flows into the amniotic water main body 10 through the discharge hole portion 32a through the second check valve 74 and is discharged to the outside through the discharge port 12, The ground water raised to the upper portion of the pipe 32 is drained without being discharged to the outside of the operation pipe 32 by the operation of the second check valve 74.

The operating portion 80 of the present embodiment includes a lever member 82 provided on the amniotic water main body 10 to convert the operation force of the user into an ascending and descending motion of the operation pipe 32, And a hinge portion (84) rotatably connected to the pumping body (10).

When the user repeatedly rotates the lever member 82 upward and downwardly, the lever member 82 is rotated about the hinge portion 84 to move the operation pipe 32 to the positive water main body 10 and the connection main body 14, It is repeatedly raised or lowered inward or outward.

The detachable connection portion 50 of the present embodiment includes a first threaded portion 52 that is machined into a connecting pipe extending outwardly from the hole portion of the partition wall panel 36 and a second threaded portion 52 which is connected to the connecting body 14 And a second threaded portion 54 which is bolted to the first threaded portion 52.
