Abstract
The utility model discloses a sewer dredger. The sewer dredger comprises an air duct, a tubular screw and a rubber expansion cylinder sleeved on the tubular screw, wherein one end of the tubular screw is conical, and the other end of the tubular screw is provided with a conical pad and a gland nut; and one end of the tubular screw is connected with the air duct. While implementing an operation of cleaning and dredging the sewer, the port of the sewer is completely sealed and blocked through the rubber expansion cylinder, so as to avoid weakness of instantaneous impact pressure due to splashing or air leakage of dirty water, and accumulate the instantaneous impact pressure to achieve the best dredging effect. The sewer dredger disclosed by the utility model is good in dredging effect, strong in practicability, low in construction cost, wide in application range and high in economic benefit, and such technical scheme can bring about considerable economic benefit.
Description
Technical field
The utility model relates to the dredging device technical field of clearing up sewer pipe, relates in particular to a kind of unbloking device for sewer.
Background technology
Existing unbloking device for sewer has two kinds, first air pressure type sewer pipe dredging device, be commonly called as " big gun is logical " or " one gets through ", by center rubber dish plug with holes, rely on people's hand to get lodged in the sewer pipe oral area, then air compressing in the compression air reservoir with the moment opening and closing device, after reaching certain pressure, abrupt release compressed air, enter in sewer pipe from the centre bore of rubber dish plug, thereby apply moment impact pressure for the obstruction in sewer pipe, be able to obstruction is dispelled out, reach the effect of dredging sewer pipe.Air pressure type sewer pipe dredging device although it is so, the sewer pipe of double blocked state also plays certain effect to a certain extent, but for the obstruction that stops up durablely, limited like this moment impact pressure still is not enough to play the dredging effect that dispels; And because the strength and stamina of staff is limited, cause rubber dish plug to press stifled sewer pipe oral area not tight, and allow addle splash everywhere on the one hand, cause on-the-spot the pollution even to pollute operating personnel's whole face all over the body; Gas leakage weakens compressed-air actuated pressure and namely weakens moment impact pressure on the other hand, and the dredging effect is had a greatly reduced quality; Repetitive operation, each moment impact pressure can not form the surge of accumulation, just repeats simply to do work not have a good dredging effect.It two is spiral unbloking device for sewer, and a kind of pipeline drainer as CN200820223607.6 announces comprises handle, dredging pipe and motor, and the rotation of driven by motor dredging pipe is characterized in that: the head of the dredging pipe spiral wire of cleaning the street.Adopt the rotation of driven by motor dredging pipe, often use, damage sewer pipe and can hardly be avoided, the sewer pipe maintenance needs huge workload and maintenance cost, makes troubles for resident's life.
The utility model content
The utility model provides that a kind of dredging is effective, practical, cost is low, applied range, economic benefit are high, is applicable to dredge various difficult obstructions, can connect a kind of unbloking device for sewer that air exhauster is made negative pressure.
Realize that the technical scheme that above-mentioned purpose is taked is: a kind of unbloking device for sewer, comprise wireway, tubular screw and be sleeved on rubber swelling cylinder on tubular screw, one end of described tubular screw is bullet, the other end is provided with tapered pad and clamp nut, and an end of described tubular screw is connected with described wireway.
Described tubular screw is provided with return spring.
Described wireway one end is provided with snap joint or valve cock.
One end of described tubular screw adopts snap joint or nut to be connected with described wireway.
Described wireway adopts flexible metal conduit.
The utility model is achieved in that puts into sewer pipe with the utility model, the clamp nut that turns clockwise, and clamp nut promotes tapered pad, extruding rubber swelling cylinder, and compression retracteding position spring, return spring shrinks; Under the effect of tubular screw, the two ends of rubber swelling cylinder produce tension force, and it is large that volume becomes, sewer pipe wall and rubber swelling cylinder are tight-closed, then use pump clip, clamp the valve cock inflation, gas enters sewer pipe and moves downward, thereby foreign material in sewer pipe are discharged; Dredge completely, clamp nut is rotated counterclockwise, loosening pressed nut, under the effect of return spring, tapered pad moves upward, and long-pending the diminishing of rubber swelling cylindrical shell attenuates, and at this moment can easily extract the utility model, and sewer pipe just can normally use.Therefore, in the time of the operation of the utility model cleaning dredging sewer pipe, by the rubber tube complete airtight shutoff of expanding, can not cause addle to splash, can not leak gas and weaken moment impact pressure the sewer pipe oral area, and can allow moment impact is pressure accumulated reaches best dredging effect.
Dredging of the present utility model is effective, practical, cost is low, applied range, economic benefit are high, be applicable to dredge various difficult obstructions, can connect air exhauster and make negative pressure, obstruction in pipeline can be inhaled pine, can reach better dredging effect, so technical scheme will be brought considerable economic benefit.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of unbloking device for sewer comprises wireway 1, tubular screw 4 and is sleeved on rubber swelling cylinder 7 on tubular screw that an end of described tubular screw 4 is bullet 9, the other end is provided with tapered pad 6 and clamp nut 5, and an end of described tubular screw 4 is connected with described wireway 1; Described tubular screw 4 is provided with return spring 8, and described wireway 1 one ends are provided with snap joint or valve cock 2, and an end of described tubular screw 4 adopts snap joint or nut 3 to be connected with described wireway 1, and described wireway 1 adopts flexible metal conduit.
The utility model is achieved in that puts into sewer pipe with the utility model, the clamp nut that turns clockwise, and clamp nut promotes tapered pad, extruding rubber swelling cylinder, and compression retracteding position spring, return spring shrinks; Under the effect of tubular screw, the two ends of rubber swelling cylinder produce tension force, and it is large that volume becomes, sewer pipe wall and rubber swelling cylinder are tight-closed, then use pump clip, clamp the valve cock inflation, gas enters sewer pipe and moves downward, thereby foreign material in sewer pipe are discharged; Dredge completely, clamp nut is rotated counterclockwise, loosening pressed nut, under the effect of return spring, tapered pad moves upward, and long-pending the diminishing of rubber swelling cylindrical shell attenuates, and at this moment can easily extract the utility model, and sewer pipe just can normally use.Therefore, in the time of the operation of the utility model cleaning dredging sewer pipe, by the rubber tube complete airtight shutoff of expanding, can not cause addle to splash, can not leak gas and weaken moment impact pressure the sewer pipe oral area, and can allow moment impact is pressure accumulated reaches best dredging effect.
Dredging of the present utility model is effective, practical, cost is low, applied range, economic benefit are high, be applicable to dredge various difficult obstructions, can connect air exhauster and make negative pressure, obstruction in pipeline can be inhaled pine, can reach better dredging effect, so technical scheme will be brought considerable economic benefit.
