Abstract
The utility model discloses a negative pressure dredging device for a drain pipe and belongs to the technical field of drain pipeline dredging. The negative pressure dredging device aims at overcoming the defects of the currently adopted drain pipe dredging method that the dredging effect is poor, and the drain pipe is easy to damage. The negative pressure dredging device comprises an inspection well and a drain pipe and is provided with a negative pressure box; a bleeder valve and an air suction valve are mounted on the negative pressure box; one end of the bleeder valve is communicated with a bleeding device by a bleeding pipe; an air suction pipe is mounted at one end of the air suction valve; and a soft plug is mounted at the other end of the air suction pipe. The dredging device is applicable to dredging blocked drain pipelines in a city.
Description
Technical field
The utility model relates to a kind of dredging technology of drainage pipe, particularly relates to a kind of gutter negative pressure dredging device.
Background technology
Along with China reforms and opens up to the outside world over 30 years, particularly since government advocated the urbanization target, a large amount of people in the countryside became the town dweller, in the city, the density of building and the occupation rate of road greatly improve, and the ratio of the mud ground that originally can be used for seeping water is significantly dwindled; In addition, also have the structure of a large amount of underground deep layers to cut off the road warp that is seeped water in original soil.So the draining task in city is just fully fallen on the body of drainage pipe now, not only will get rid of the productive life sewage that produces in the every day of the city, but also will flow greatly anxious rainwater in rainy day eliminating amount.Can say, drainage pipe has had indispensable meaning for a city.As everyone knows, at sewage, when rainwater flows into drainage pipe, can carry more or less silt rubbish secretly, therefore, drainage pipe very easily stops up.At present, the method in the dredging drainpipe road taked of people is to disclose cutter with instruments such as bamboo chip, plastic strips.Due at the formed obstruction point of drainage pipe, be that some colmatation zones can be very abundant through the accumulation of the foreign material such as silt rubbish after a while; And the nidus that stops up also has a lot of obstruction points to occur in and leaves all central region of pipeline section far away of before and after look well often in the junction of pipeline; Therefore, present dredging method, the one, be the local point-like application of force to obstruction, even disclose a hole, can block very soon again, therefore the poor effect of dredging; The 2nd, because of disclose stifled instrument oversize and uncontrollable disclose stifled end force direction, very easily wound or break the tube wall of drainage pipe by stabbing, cause larger trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of gutter negative pressure dredging device, overcomes the existing dredging weak effect of drain pipe-dredging method of present employing, the deficiency of fragile gutter itself.
The utility model is achieved by following technical proposals.
The utility model comprises manhole, gutter, be provided with negative pressure box, extraction valve and inlet valve are housed on described negative pressure box, are communicated with, at described inlet valve one end, admission pipe are housed by exhaust tube and air extractor at described extraction valve one end, at the other end of described admission pipe, cork is housed.In the technical program, the effect of described negative pressure box is the storage to negative pressure, described cork plays and allows inside and the isolation of described gutter, when described inlet valve one is opened, the negative pressure that is stored in described negative pressure box just can cause very large vacuum in to described gutter in the short period, and obstruction place obstruction is due to the pressure of the direction that is subject to forming against its accumulation, and is whole pressurized, be easy to make its whole disintegration, then flow away with current.
In the utility model, described admission pipe will pass to described gutter to the negative pressure of described negative pressure box, adapt to the convenience of the mouth of pipe of different depth locations and installation, dismounting, carrying, so described admission pipe adopts anti-flat flexible pipe.Electric vacuum pump can be used for the described air extractor of bleeding for described negative pressure box, also manual suction pump can be adopted in the place that there is no power supply.In use procedure of the present utility model, described cork plays very crucial effect, should good sealing be arranged at drain pipe port side and admission pipe outer wall side but also want to adapt to the need of the described gutter of different tube diameters, therefore, described cork is that a plurality of confessions with different size are selected, the endoporus aperture of each described cork can airtightly coordinate with described admission pipe, outside the piston part through respectively according to the internal diameter manufacturing of the gutter of variant bore.
Against existing technologies, the beneficial effects of the utility model are:
Optimized the dredging effect to the drainage pipe that stops up; Avoided in the dredging process damage to gutter itself.
Description of drawings
Accompanying drawing is structural representation of the present utility model.In figure: 1, manhole, 2, gutter, 3, negative pressure box, 4, extraction valve, 5, inlet valve, 6, exhaust tube, 7, admission pipe, 8, cork.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and the specific embodiment.
The utility model must make the interior ponding of manhole 1 lower than the mouth of pipe of the gutter 2 that will dredge when drainage pipe being dredged enforcement.Admission pipe 7 and inlet valve 5 are linked; Again the other end of admission pipe 7 is filled in the mouth of pipe of gutter 2 and maintained good sealing together with cork 8.Then close inlet valve 5, open extraction valve 4, with electric vacuum pump or manual suction pump, negative pressure box 3 is bled, after negative pressure box 3 reaches higher vacuum, close extraction valve 4, open rapidly inlet valve 5, at this moment, gutter 2 is interior very large negative pressure can occur, very fast, the obstruction of obstruction place can be destroyed by powerful atmospheric pressure, and pipeline is dredged.
