The bailing device has the technical scheme: 1. the connection position of a bailing tube and a bailing cylinder is improved, and is transferred to side connection with a certain height from the bottom of the cylinder from bottom connection, and a one-way valve at the bottom of a traditional bailing device is transferred into the bailing tube of side connection with the position change of the bailing tube; 2. the structure of a piston of the bailing cylinder is improved, the piston of the traditional bailing device is mainly composed of a rubber wafer and a one-way valve fixed in the center of the piston, the novel piston is made into a piston with a certain height, a vertical guide flow groove is arranged outside the piston, and the upper opening of the flow guide groove is communicated with the one-way valve at the top of the piston; and 3. in order to lighten the weight of the piston and save materials, the piston can be made of light rubber and can be made into a hollow piston.

Description

Well water drawing device without diversion

Technical field the utility model relates to a kind of water drawing device of underground water well, has carried out the certain structure improvement based on traditional hand-operated water drawing device, and having solved it needs the problem of diversion, has promptly proposed a kind of well water drawing device that does not need diversion.

Background technique is in the China that water resources per capita lacks, and underground water is still being brought into play important effect for satisfying people's productive life needs; Particularly for northwest China and remote mountain areas thereof, underground water even become people's one of primary condition of life of relying, well remains the important component part of residential kitchen in mountainous rural area.At present, the water drawing device of well mainly is divided into two classes: electric pump draws water and the hand device draws water, and the improvement that the utility model just is being based on the hand-operated water drawing device proposes.For present hand-operated water drawing device, mainly constitute by rocking bar, piston rod, the tube that draws water, piston, bailing pipe, waste pipe, 2 one-way valves, because relation such as financial cost, technology, 2 one-way cocks in the water drawing device can't guarantee the positive confinement under the closed condition, the water storage function in the tube that also just can't realize drawing water for a long time, the water that preserve in a Central Plains that draws water along with the time slowly seepage flow in well.Therefore, the resident often need carry diversion when draw water next time, lacks the resident in area for water resources, seeks and gets not only difficulty relatively of diversion, even also be a kind of water resource waste; In addition, carry diversion at every turn also brought very big inconvenience to urbanite water consumption.

Summary of the invention is in order to solve traditional well water drawing device can't realize drawing water defective of tube length time water storage function, and the utility model has carried out having proposed a kind of well water drawing device without diversion after certain structure improves based on present well water drawing device.

The technical solution adopted in the utility model is: 1, the improvement of the bailing pipe and a link position that draws water.Bailing pipe is connected a side that moves to apart from tube end certain altitude with the link position of the tube that draws water by the bottom and connects, and the one-way valve of traditional water drawing device bottom moves on in the bailing pipe of side connection that draws water with the bailing pipe change in location; 2, the draw water improvement of piston structure in the tube.Tradition water drawing device piston mainly is made of rubber disk, the one-way valve that is fixed in the piston center, and the utility model piston then manufactures the piston with certain altitude, and at the vertical guiding gutter of piston external-open one, guiding gutter is suitable for reading to be communicated with the one-way valve of piston head; 3, in order to alleviate piston weight and to save material, piston adopts lightweight rubber or plastics, and makes hollow.

The utility model does not need the working principle of diversion to be: the resident is after certain once finishes the underground water extraction, because the not enough problem of piston gas tightness, the following water that stores of waste pipe slowly infiltration downwards in time in the tube draws water, flow back to the well from the mouth of pipe that draws water, the underwater is reduced to concordant with the mouth of pipe that draws water in the tube that draws water; But the water of part that draws water between tube bottom and the bailing pipe upper orifice owing to be lower than the bailing pipe upper orifice, can not ooze in the recharging well from start to finish, has preserved thereby be used as diversion, for the usefulness that draws water next time; When the resident extracts underground water next time, only need shake rocking bar, piston is pushed back the tube bottom that draws water, one-way cock is closed in the bailing pipe at this moment, the one-way valve opens of piston head, preserved the water that gets off because the piston extruding can flow to the piston top along the guiding gutter on the piston limit last time in the tube that draws water, form and this time extract phreatic diversion, solved the diversion problem of well water drawing device.

The beneficial effects of the utility model are: saved water resources, provide convenience for using underground water in the life of kitchen, rural area.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is an example structure schematic representation of the present utility model.

1. outlet pipes among the figure, 2. piston rod, 3. piston, 4. guiding gutter, a base that 5. draws water, 6. one-way valve one, 7. bailing pipe, 8. one-way valve two, the tube that 9. draws water, 10. rocking bar.

Embodiment

Among Fig. 1, certain resident draws water from well, at first, upwards promote rocking bar (10), piston rod (2) moves downward, then draw water piston in the tube (9) (3 with the pressure increasing that draws water between tube (9) bottom, cause one-way valve one (6) and close, one-way valve two (8) is opened, thereby the water that will be stored in tube (9) bottom that draws water pushes, flow to the top on piston (3) top after water is squeezed along the guiding gutter (4) on piston (3) limit, form diversion; After diversion has been arranged, promote rocking bar (10) downwards, piston (3) below pressure diminishes, and one-way valve one (6) is opened, and one-way valve two (8) is closed, and the water in the well will slowly be mentioned, and so repeatedly, realizes the phreatic process of drawing.When finish draw water after, because the floating function of the hollow tube (9) that draws water, piston (3) can rest on draw water the tube (9 tops are far from the position of bottom, even if like this because piston (3) tightness problem causes infiltration, draw water the tube (9) bottom still can store certain water yield as the diversion that draws water next time, solved the diversion problem of well water drawing device.

The utility model can need not add under the situation of diversion without the well water drawing device of diversion, realizes the phreatic process of drawing.

Claims (2)

1. without the well water drawing device of diversion, mainly constitute by the tube that draws water, piston, one-way valve one, guiding gutter, bailing pipe, one-way valve two, waste pipe, piston rod, rocking bar, it is characterized in that: bailing pipe is connected a side that draws water, the tube bottom that draws water sealing, piston has guiding gutter on the limit, the guiding gutter upper outlet is communicated with the one-way valve of piston head, and guiding gutter outlet down flushes with piston base.

2. the well water drawing device without diversion according to claim 1 is characterized in that: piston material is lightweight rubber or plastics, and is hollow-core construction.
