Description

Manual type water pump

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hand operated water pump used in a ground water tank, etc., and more particularly, to a manually operated water pump capable of lifting ground water even when there is no priming water by installing a cylinder in a well.

Generally, a water pump is a device that can pumped groundwater to the ground. In such a water pump, there are a manual water pump for pumping ground water by the worker and an automatic water pump for pumping ground water 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 attain the above object, the manual water pump of the present invention comprises a bending pipe member bent in a manner bent to be positioned in the ground, an external force applying member capable of applying an external force to the operator, The bending pipe member includes an inlet-side check valve for preventing back flow of groundwater introduced into the U-shaped valve, and a check valve for preventing reverse flow of the groundwater flowing through the outlet. And the inlet side check valve is located at a lower portion of the bent pipe member and is located at the ground surface and is in the shape of a cap and is provided with a tubular cap having an outer flange portion, The outflow of which is exposed to the ground; Wherein the external force application member includes a support stand erected with respect to the ground surface, a lever pivotal portion pivotally connected to the support, a lever movably connected to the lever pivoted portion, A lever pivoting piston connecting portion; Wherein the pressure member includes a cylinder communicating with the bending pipe member and installed in a well, a piston capable of applying pressure to the bending pipe member while being moved in the cylinder, and a piston projecting from the piston into the bending pipe member And a sealing member enclosing the outer periphery of the piston to seal the space between the inner walls of the cylinder. When the piston rises, the inlet-side check valve is opened, and the groundwater introduced into the bending- And is pushed toward the outlet of the bending pipe member and pumped to the ground.

In addition, the present invention is characterized in that the external force applying member includes a lever which can apply an external force via one end of the worker, a lever connected to the pressing member, a groundwater receiving case 416 in which groundwater flowing out through the outlet of the bent pipe member is contained, A connection portion connecting the groundwater accommodating case to the other end of the lever; and a groundwater outlet for allowing the groundwater accommodated in the groundwater accommodating case to flow out of the groundwater accommodating case when the groundwater is received by a predetermined load in the groundwater accommodating case And the like.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention can be modified into various forms and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that the same components are denoted by the same reference numerals in the drawings. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

1, the manual water pump 100 according to the present embodiment includes a bending pipe member 130, an external force applying member 110, and a pressing member 120, ) Can be pumped.

The bent pipe member 130 is formed with an inlet 131 through which the groundwater flows into the ground 10. The inlet 131 is located below the U-shaped bent pipe member 130, An outlet 132 through which the groundwater flows out is exposed to the ground and is buried in the ground 10 in a bent form so that the body is located at the ground 10.

Specifically, the bending pipe member 130 may be installed in the excavation hole 20, which is excavated from the ground surface to the ground 10 at a predetermined depth and the groundwater is seeped and filled.

The bent pipe member 130 is formed in a U shape, and most of the U-shaped body is buried in the excavation hole 20. One of the two legs of the U-shaped body is a portion exposed on the ground, For example, the outlet 132 is formed at the distal end.

An inlet-side check valve 140 is installed in the inlet 131 of the bent pipe member 130 to prevent backflow of the groundwater flowing through the inlet 131. Since an ordinary check valve can be applied to the inlet-side check valve 140, a detailed description and a detailed description thereof will be omitted here.

The outlet 132 of the bent pipe member 130 is formed in the same direction as the direction in which the groundwater flows in the portion embedded in the ground 10 of the bent pipe member 130. That is, when the portion of the bent pipe member 130 embedded in the ground 10 is installed perpendicular to the ground, the groundwater flows in a direction perpendicular to the ground at the portion buried in the ground 10 In this case, the outlet 132 of the bent pipe member 130 is also formed in the vertical direction in which the groundwater flows.

Even if freezing is formed due to condensation of moisture at the outlet 132 of the bent tube member 130 during the winter, the pressure of the pressing member 120 transmitted through the bent tube member 130 may cause such The freezing can be pushed out, so that the unusable phenomenon of freezing of the manual water pump 100 due to freezing in winter can be prevented.

An outlet check valve 145 is provided at the outlet 132 of the bending tube member 130. The outlet check valve 145 is connected to the outlet 132 of the bending tube member 130, Thereby preventing backflow of the groundwater. Since an ordinary check valve can be applied to the outlet-side check valve 145, its detailed description and illustration will be omitted here.

In the present embodiment, the lower end of the external force applying member 110 is fixed on the ground, and the upper end is fixed to a certain portion of the lever 111 A lever 111 that is rotatably connected to the support base 112 within a predetermined angle range and a lever 111 that connects one end of the lever 111 to a piston 122 A cylinder fixing portion 114 for firmly supporting the piston connecting portion 113 and the cylinder and a bending prevention ring 115 for preventing the bending of the piston connecting portion 113.

The lever 111 is formed in a lever shape elongated at one side with respect to a point connected to the supporter 112. An operator can press an end of the lever 111 to apply an external force through the one end of the lever 111, And the lever piston connecting portion 113 is connected to an end thereof. When an operator presses one end of the lever 111, the lever piston connecting portion 113 and the piston 122 connected thereto are lifted. When the operator lifts one end of the lever 111, The lever piston connecting portion 113 and the piston 122 connected thereto may be lowered.

The pressing member 120 is operated by an external force applied by the external force application member 110 so that the groundwater in the bending pipe member 130 is pushed toward the outlet 132 of the bending pipe member 130 A cylinder 121 communicating with a side of the bent pipe member 130 where the inlet 131 is formed by applying pressure to the bent pipe member 130 and located in the groundwater; Which is capable of applying pressure to the bending tube member 130 while being lifted and lowered.

The lever piston connecting portion 113 and the piston 122 connected thereto are lowered so that the piston 122 is lowered in the cylinder 121. As a result, So that the groundwater in the bending tube member 130 can flow out through the outlet 132 in the bending tube member 130. In this way,

In the present invention, since the cylinder 121 is located in the groundwater and the piston 122 inside the cylinder 121 is always kept in the groundwater, , You can freely pumped without the need for additional priming.

The concrete operation of the manual water pump 100 will be described below.

First, when an operator presses one end of the lever 111, the lever piston connecting portion 113 and the piston 122 connected thereto are raised.

At this time, the inlet-side check valve 140 is opened and groundwater of the ground 10 flows into the bending pipe member 130 through the inlet 131 of the bending pipe member 130. During the inflow of the ground water, the outlet check valve 145 is closed so that a negative pressure is applied to the inside of the bent pipe member 130, The groundwater in the bending pipe member 130 can be introduced into the bending pipe member 130.

After the groundwater flows into the bending pipe member 130 and the operator applies an external force to the one end of the lever 111 as described above, the lever piston connecting portion 113 and the piston 122 are lowered so that the piston 122 is lowered in the cylinder 121 and pressure is applied into the bending pipe member 130. [ The groundwater flowing into the bent pipe member 130 is pushed by the pressure toward the outlet 132 via the bent portion of the bent pipe member 130.

At this time, the inlet-side check valve 140 is closed and the outlet-side check valve 145 is opened, so that the groundwater inside the bent pipe member 130 flows toward the outlet 132.

As described above, the groundwater pushed toward the outlet 132 flows out through the outlet 132 and is pumped up to the ground.

After the pumping is completed as described above, when the operator again presses one end of the lever 111, the lever piston connecting portion 113 and the piston 122 connected thereto are lifted, And can be returned to its original position in the cylinder 121.

Therefore, the pressure applied by the pressing member 120 directly pushes the water in the bending pipe member 130, so that the pumping can be performed with a relatively small force as compared with the method in which the groundwater is pulled up, The present invention can be applied to a place where the groundwater level of the manual water pump 100 is low as well as the cylinder and the piston of the manual water pump 100 are not damaged by foreign substances such as sand mixed in the ground water, Can be improved.

The groundwater outflow portion includes a plurality of guide protrusions protruding from the groundwater accommodating case 126 while being separated from each other and a guide panel 127 having a plurality of guide protrusions inserted and guided by the guide grooves. The guide grooves are curved at a predetermined curvature so that when the plurality of guide protrusions are located at one end portion of the guide groove, for example, at the highest point portion, the groundwater accommodating case 126 can receive the groundwater When the groundwater container 126 is lowered into the groundwater container case 126 and the plurality of guide protrusions are moved along the guide grooves 126, And when a plurality of the guide projections are positioned at the other end portion of the guide groove, for example, at the lowest point portion, the groundwater receiving case 126 is in a state in which the groundwater accommodated overturned and is accommodated can be poured out do.
