Background technique
At present, along with greatly developing of machinery, many rural areas do not adopt Traditional Man to dig a well, and adopt machine drill to drink well, and the bore of drinking well due to machine drill is little, and farmers' adopts pumped well water intaking mostly.Present stage, pumped well was on the market mostly without leakage-proof apparatus, or preventing water leakage sealing not, and setting-out is long interval time one, because of leaking, and caused the oil hydraulic cylinder of pumped well interior anhydrous and cannot extrude water.This just causes each setting-out all will be to pouring after diversion setting-out again in pumped well into, and this bothers very much
Model utility content
The purpose of this utility model is for above-mentioned deficiency, proposes a kind of pumped well that can leakproof.
The technical solution adopted in the utility model is:
A kind of leakproof pumped well, comprise setting-out bar, oil hydraulic cylinder and annular piston, the cofferdam of catchmenting is installed at described oil hydraulic cylinder top, described cofferdam one side of catchmenting is installed water outlet, suction sleeve socket is installed in described oil hydraulic cylinder bottom, described setting-out bar is connected with piston Drag link one end, the other one end of described piston Drag link is connected with piston holder, cofferdam and described oil hydraulic cylinder catchment described in described piston Drag link passes, described piston holder is connected with described annular piston, one-way valve is installed at described annular piston middle part, it is characterized in that, the water inlet fixing seal ring of the bottom of described oil hydraulic cylinder, on described seal ring, sealing plug is installed, fixed network hole, described oil hydraulic cylinder bottom positioning cover plate, the position of described mesh positioning cover plate is above described sealing plug.
Preferably, described piston holder is that semicircle is spherical.
Preferably, described seal ring is O type seal ring.
Preferably, described mesh positioning cover plate is circular.
Further, sealing plug directional post is installed at described sealing plug middle part, and positioning and guiding pipe is installed in described mesh positioning cover plate lower end, and described positioning and guiding pipe is inserted in described sealing plug directional post.
Further, described positioning and guiding pipe is inserted in described sealing plug directional post, between the two retention gap.
Closer, described positioning and guiding pipe on have through hole.
The beneficial effects of the utility model are:
This apparatus structure is simple, and cost of production is low; This device utilizes distinctive leakage proof structure, can guarantee that pumped well, in when work, can not produce any leaking, except setting-out for the first time will be poured into diversion, and setting-out any time later, all directly setting-out is out; This device is reasonable owing to configuring simultaneously, and compact structure is durable not perishable.
Accompanying drawing explanation
The structural representation of a kind of leakproof pumped well that Fig. 1 provides for the utility model embodiment.
In figure: 1, setting-out rod bearing, 2, setting-out bar, 3, one-way valve, 4, annular piston, 5, oil hydraulic cylinder, 6, mesh positioning cover plate, 7, positioning and guiding pipe, 8, suction sleeve socket, 9, O type seal ring, 10, sealing plug, 11, sealing plug directional post, 12, piston holder, 13, water outlet, 14, the cofferdam of catchmenting, 15, piston Drag link.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
With reference to Fig. 1, the present embodiment provides a kind of leakproof pumped well, comprises setting-out bar 2, oil hydraulic cylinder 5 and annular piston 4.The cofferdam 14 of catchmenting is installed at oil hydraulic cylinder 5 tops, and cofferdam 14 1 sides of catchmenting are installed water outlet 13.Suction sleeve socket 8 is installed in oil hydraulic cylinder 5 bottoms.Setting-out bar 2 and setting-out rod bearing 1 hinge, setting-out bar 2 is connected with piston Drag link 15 one end, and the other one end of piston Drag link 15 is connected with piston holder 12, and piston holder 12 is that semicircle is spherical.Piston Drag link 15 is through catchmenting cofferdam 14 and oil hydraulic cylinder 5.Piston holder 12 is connected with annular piston 4, and one-way valve 3 is installed at annular piston 4 middle parts.The water inlet of the bottom of oil hydraulic cylinder 5 is O type seal ring 9 fixedly, on O type seal ring 9, sealing plug 10 is installed.Oil hydraulic cylinder 5 bottoms are mesh positioning cover plate 6 fixedly, the position of mesh positioning cover plate 6 above sealing plug 10, mesh locating cover, 6 is circular.Sealing plug directional post 11 is installed at sealing plug 10 middle parts, and positioning and guiding pipe 7 is installed in mesh positioning cover plate 6 lower ends, and positioning and guiding pipe 7 is inserted in sealing plug directional post 11, and retention gap, has through hole on positioning and guiding pipe 7 between the two.
When this device first work, pour appropriate diversion in this device, with hand tension and compression setting-out bar 2 up and down reciprocatingly, at this moment under the effect of water seal: when when handing up tension and compression water bar 2, annular piston 4 moves down, and due to sealing plug 10 sealings, the air in oil hydraulic cylinder 5 is discharged through one-way valve 3.When with hand when pressing down setting-out bar, annular piston 4 moves up, at this moment one-way valve 3 is closed, simultaneously sealing plug 1) open, under the effect of the negative pressure in oil hydraulic cylinder 5, the water in suction sleeve socket 8 rises along pipeline, enters in oil hydraulic cylinder 5.
When water enters after oil hydraulic cylinder 5, while upwards lifting setting-out bar 2 again with hand, annular piston 4 moves down, and due to sealing plug 10 sealings, the water in oil hydraulic cylinder 5 flows to above annular piston 4 through one-way valve 3 tops.With hand when pressing down setting-out bar 2, annular piston 4 moves up, at this moment one-way valve 3 is closed, sealing plug 10 is opened simultaneously, at this moment annular piston 4 water above flows out through water outlet 13, and under the effect of the negative pressure in oil hydraulic cylinder 5, the water in suction sleeve socket 8 rises along pipeline, enter in oil hydraulic cylinder 5, this has just had clear water endlessly to flow out.
When stopping fetching water, by 10 sealings of, sealing plug, in pumped well, water can not missed, later setting-out direct setting-out all any time.
This apparatus structure is simple, and cost of production is low; This device utilizes distinctive leakage proof structure, can guarantee that pumped well, in when work, can not produce any leaking, except setting-out for the first time will be poured into diversion, and setting-out any time later, all directly setting-out is out; This device is reasonable owing to configuring simultaneously, and compact structure is durable not perishable.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
