Abstract
The utility model relates to a device for fetching underground water. A first elastic pad for sealing a through hole is installed on the upper surface of a piston of the device, and a one-way valve is installed at the position of a piston cylinder connected with an underground water pipe. The piston in the device and the one-way valve are separated at a certain distance, and the piston can enable negative pressure to be generated in the underground water pipe in vertical movement, so that water is required to be injected into the piston cylinder when the device pumps the water.
Description
Technical field
The utility model relates to a kind of phreatic device of getting.
Background technique
Tradition is got phreatic device; Comprise a piston that the cylinder body that is connected with the foggara upper end is interior with being installed in this cylinder body; And piston is provided with through hole and is installed in the round rubber pad that piston upper surface is used to cover through hole, and the upper end and the depression bar of piston are hinged.When groundwater abstraction, at first, when being moved up and down, piston produces negative pressure under the effect of depression bar, underground water is extracted out through buried pipe at a certain amount of water of perfusion in cylinder body.Though this kind device manual mode capable of using is extracted underground water out, because the round rubber spacer has relatively large surface area, and need open very big angle when drawing water, thereby is prone to cause its premature damage; Simultaneously slower because of round rubber pad return speed, in the process of drawing water, understand some water and return in the buried pipe, and then influence the efficient of drawing water, and waste time and energy.
The name of No. 200320105216.1 notice of authorization of Chinese patent is called " a kind of hand well " and proposes a solution.This patent is employed on the piston in the piston cylinder and offers passage, and passage is provided with a valve, and is provided with Movable valve in the piston cylinder bottom, and its meaning is the aqueous reflux of wanting to utilize Movable valve to hinder and being drawn out of.Though the hand well of this kind structure can improve the efficient of drawing water; Can reduce labor intensity, but because the structure relative complex of Movable valve, fabricating cost is higher relatively; And valve that is provided with on the passage and Movable valve very easily damage under the frequent impact of water, cause shorten its working life.
Summary of the invention
The purpose of the utility model is to provide a kind of mode of utilizing segmentation to draw water to solve the phreatic device of getting of problem such as short and operating difficulties in working life.
The phreatic device of getting that the utility model proposed has a piston cylinder that is installed in the foggara upper end portion; Piston rod upper end in the piston cylinder is hinged with depression bar; The lower end is equipped with piston; Said piston is provided with through hole, at the upper surface of through hole first cushion that is used to seal through hole is installed, and the position that is connected with foggara at piston cylinder is equipped with one-way valve.
Said one-way valve has a plate that axially is provided with through hole, and second cushion also is installed above plate.Through hole and the through hole on the plate on the said piston are respectively arranged with six, and are provided with the plate identical with number of openings on first cushion and second cushion.
First cushion and second cushion got in the phreatic device that the utility model proposed all adopt plate to cover through hole, because the area of plate is less relatively, when drawing water; First cushion and second cushion got in the phreatic device that are proposed all adopt plate to cover through hole; Because the area of plate is less relatively, when drawing water, only need less external force just can open it; So this device can not prolong its working life simultaneously in the labour-saving; In addition, between between piston and the one-way valve, be separated with certain distance, when piston moves up and down, just can make to produce negative pressure in the foggara, so this device does not need water filling in piston cylinder earlier before drawing water.
Description of drawings:
Accompanying drawing 1 is the outward appearance cross-sectional view of getting an embodiment of phreatic device that the utility model proposes;
Accompanying drawing 2 is decomposing schematic representations of one-way valve among Fig. 1;
Accompanying drawing 3 is cross-sectional view of piston among Fig. 1.
Embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure of getting an embodiment of phreatic device that the utility model proposes.This device comprises piston cylinder 1 and the piston rod 4 that is installed in the piston cylinder 1, and piston rod 4 upper ends and depression bar 3 are hinged, and in the lower end of piston rod 4 piston 2 are installed, and the end that the bottom of piston cylinder 1 and foggara 5 join is equipped with one-way valve 6.
Referring to Fig. 2, this figure provides 6 one decomposing schematic representations of one-way valve.One-way valve 6 has a plate 62 that axially is provided with through hole 61; Through hole 61 is provided with six circular ports; It is the plates that are made up of rubber material that second cushion, 63, the second cushions 63 also are installed above plate 62, is provided with the plate that is used for covering respectively each through hole 61 above that; The middle part of second cushion 63 is provided with an axial bore 64, the second cushions 63 and is fixed on the plate 62 through bolt 65 and pressure cap 66.
Referring to Fig. 3, this figure provides 2 one embodiments' of piston the outer whole knot schematic representation of seeing.Piston 2 has a plate 21; Plate 21 axially be provided with one-way valve 6 on the quantity through hole identical with shape; It is the plates that are made up of rubber material that first cushion, 22, the first cushions 22 also are installed above plate 21, is provided with the plate that is used for covering respectively each through hole above that; The middle part of first cushion 22 is provided with an axial bore 23, and the plate 21 and first cushion 22 are fixed in the lower end of piston rod 4 through bolt 24 and pressure cap 25.
When drawing water, the water in the foggara 5 is drawn into earlier in the space between piston 2 and the one-way valve 5, and then is drawn into the top of piston 2.
