Abstract
The utility model relates to a sanitary cleaning tool, particularly a device for removing obstruction in a sewer, which comprises a draw rod which is connected with a piston rod, the piston rod is connected with a piston, and the integral body of the piston rod and the piston which are connected is sheathed with a suction pipe; the piston is provided with a sealing ring, the suction pipe is provided with a positioning piece and the periphery of the bottom of the suction pipe is provided with a sealing disc. The utility model provides a device for removing obstruction in a sewer, having the advantages of simple and reasonable structure, convenient operation, long service life and cost saving and solves the technical problems of low obstruction removing efficiency and high labor intensity for maintenance personnel existing in the prior art.
Description
Technical field
The utility model relates to a kind of cleaning gear, relates in particular to a kind of sewer dredger.
Background technology
At present, the sewerage system of each corridor of building is sometimes when the sewer pipeline is installed in building operations, sneak into foreign matter or user's improper use in daily life in the pipe, enter easy obstruction in the pipe, with make and the sewage draining exit that joins of sewage well to one section between the corridor sewer bend part, blockage phenomenon often.Sewage is excessive from the urinal or the inlet of sewer of Stall during obstruction, brings inconvenience for user's daily life of Stall.After sewer stops up, to ask the mediation personnel of specialty generally speaking, disassemble the gland that sets in advance at Stall user's dredging sewer hole flange, utilize special tool to dredge.Stop up when serious, sewage well to the segment pipe that the corridor sewer stops up be excavated, pipe is stopped up in dismounting, dredges, and also will change corresponding pipeline in the time of can't dredging.Increase extra financial burden so not only for all users of this corridor, and increased maintenance personal's labour intensity.Also wanting a kind of on the market now is a wooden stick that bowl-shape rubber is housed, and utilizes atmosphere negative pressure to become flexible obstruction, this mediation extracting of will repeatedly exerting oneself, and also sewage or obstruction advance to spatter easily.
Summary of the invention
The utility model mainly provides a kind of simple and reasonable, and is easy to use, and long service life is repeatedly saved the sewer dredger of cost; It is low to solve existing in prior technology mediation efficient, the technical problem that work maintenance personal labour intensity is big.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of sewer dredger, comprise pull bar, pull bar is connected with piston rod, be connected with piston on the piston rod, the integral sleeve that piston rod is connected with piston is connected to suction pipe, be provided with sealing ring on piston, be provided with spacer on suction pipe, periphery, suction pipe bottom is provided with seal disc.Piston is provided with sealing ring and makes that suction pipe sealing shape is better, thereby logical sewer is more convenient succinct, in periphery, suction pipe bottom seal disc is set, the material of seal disc is a rubber, and the material of suction pipe is plastics, the two material is all lighter, and low price, seal disc is thinner, has replaced original rubber cup, saved material, it is also comparatively convenient to carry.
As preferably, described spacer and suction pipe are one.Spacer and suction pipe integral cast, technology is simple, and is easily manufactured.The setting of spacer is the relative position for steady brace, makes it be in the center of suction pipe.
As preferably, the bottom of described suction pipe is provided with annular outer.Diameter for fear of the hole of suction pipe is too big, and a flange is set in the bottom of suction pipe, forms an annular outer, is pasting seal disc on the outer more like this.Not only avoid the suction pipe diameter excessive, also saved the material of seal disc.
As preferably, the peripheral diameter of the sealing ring on the described piston is slightly larger than the suction pipe internal diameter, and piston diameter is equal to or less than the suction pipe internal diameter.The peripheral diameter of sealing ring is greater than the suction pipe internal diameter, and sealing is better, and piston inner diameter is not more than the suction pipe internal diameter and makes that twitch is more convenient.
As preferably, described piston is connected by bolt with piston rod.Piston and piston rod are by being threaded, and both can break like this, if simultaneously badly one kind of, change easily.
As preferably, described suction pipe is provided with steam vent.The setting of steam vent is in order to make the air pressure in the suction pipe moderate, easier dredging sewer.
As preferably, described suction pipe internal diameter is 40-80mm, and suction pipe length is 350-500mm.
Advantages such as therefore, the utlity model has simple in structurely, reasonable in design, easy to use, cost is low, and the life-span is long.
Description of drawings:
The concrete example of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of sewer dredger comprises pull bar 1, and the piston rod 2 that links to each other with pull bar 1 is threaded in the employing of the bottom of piston rod 2, is fixed with piston 3 with bolt 8.Be provided with sealing ring 5 in the centre of piston 3, the external diameter of sealing ring 5 is greater than the internal diameter of suction pipe 4, and the diameter of piston 3 is not less than the internal diameter of suction pipe 4, makes that the pressure in the suction pipe 4 can the interior obstruction of sucking-off sewer.The internal diameter of suction pipe 4 is 40mm, and length is 350mm.Spacer 6 with suction pipe 4 integral casts is arranged on the top of suction pipe 4, and it all is to adopt plastics to make.Spacer 6 is the center of circle with piston rod 2.The setting of spacer 6 is the relative positions for fixed piston rod 2 and pull bar 1, the pull bar 1 movable stroke when being fit to draw obstruction.Outer, bottom at suction pipe 4 is provided with seal disc 7, the material of seal disc 7 is a rubber, excellent adsorption, during obstruction in drawing sewer, seal disc 7 is by the difference of inside and outside pressure, hold the place around the sewer, also be provided with a steam vent 9 on the top of suction pipe simultaneously, make to form certain pressure in the suction pipe 4.
Embodiment 2:
As shown in Figure 1, a kind of sewer dredger comprises pull bar 1, and the piston rod 2 that links to each other with pull bar 1 is threaded in the employing of the bottom of piston rod 2, is fixed with piston 3 with bolt 8.Suction pipe 4 internal diameters are 48mm, and length is 400mm, outwards are provided with one ring-type outer in the bottom of suction pipe 4, and it is too big for fear of the internal diameter of suction pipe that the outer is set, and has saved the material of seal disc 7 simultaneously.All the other structures and embodiment 1 are together.
