Description

Technical Field

[0001] The invention relates to a sewage pipe plugging system suitable for high water level operation and a use method thereof, and is applicable to the technical field of municipal sewage pipe plugging. Background Art

[0002] During the long-term operation of urban sewage pipes, a large amount of floating garbage and silt may accumulate in the pipes, affecting the normal operation of the pipes, and even causing structural defects in the pipes due to long-term corrosion of sewage. When the above situation occurs, it is necessary to carry out dredging or repair projects on the pipes. The preparation work for the above projects requires blocking the upstream of the pipes and pumping the sewage to the second sewage inspection well downstream.

[0003] At present, there are two ways to seal sewage pipes: the first is to use brickwork, where cement bricks are used to seal the sewage pipe mouth; the second is to use air bags to seal the air bags, where high-pressure gas is injected into the sewage pipe, and the air bags are inflated to seal the pipe section.

[0004] Both of the above existing methods have defects: (1) When bricks are used for sealing, the bricks cannot be reused, and it is difficult to remove them and they may not be completely removed, resulting in clogging in the pipe again; (2) Brick sealing is more difficult when the water level is high, and cement is difficult to solidify quickly, resulting in a loose seal; (3) Although air bag sealing can be reused, the air bag requires people to enter the inspection well to insert it into the sewage pipe. In actual operation, there have been safety accidents in which the air bag was stunned during the high-pressure inflation process; (4) The water level in the sewage main pipe is relatively high. Whether air bag or brick sealing is used, people need to enter the inspection well room. There are many toxic substances in the sewage, and there may be a large amount of hydrogen sulfide gas in the well, posing a serious threat to personal safety. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the above-mentioned problems, a sewage pipe blocking system suitable for high water level operation and a method of use are provided.

[0007] Desilting device, used to clean the entrance of sewage pipe;

[0008] An airbag blocking device, comprising an airbag, for blocking the inlet of the sewage pipe after being cleaned by the desilting device through the airbag;

[0009] An airbag installation device, used for remotely installing the airbag to the entrance of a sewage pipe;

[0011] The airbag is placed between two crossbars of the bag installation device. The airbag is connected to two traction ropes. The two traction ropes are respectively wound around the pulleys I and II on the two side crossbars in sequence and then extend upward along the vertical telescopic mechanism to connect the traction mechanism.

[0012] The desilting device comprises a rotating cleaning head adapted to the inner wall of the sewage pipe, and a rotating driving mechanism for driving the rotating cleaning head to rotate.

[0013] The rotary cleaning head is composed of a cone section, a cylinder section I and a cylinder section II from front to back along its axis, wherein the surfaces of the cone section and the cylinder section I are provided with threads, and the surface of the cylinder section II is provided with a brush.

[0014] The rotary drive mechanism comprises a rotating shaft and a retractable main shaft, the rotating shaft is coaxially connected to the rotary cleaning head, the upper end of the main shaft is connected to the motor, and the lower end of the main shaft is rotatably connected to the rotating shaft.

[0015] The rotating shaft is installed on the placement cabinet and is connected to the main shaft through a disc gear and a main shaft gear transmission.

[0016] The bottom of the placement cabinet is provided with rollers via a telescopic shaft.

[0017] The vertical telescopic mechanism comprises two telescopic vertical rods respectively connected to the two horizontal rods, and the two telescopic vertical rods are connected via a plurality of connecting rods.

[0018] The vertical telescopic mechanism is provided with a clamping piece I which can be matched with the wellhead of the sewage inspection well to realize clamping.

[0019] The cross bar is provided with a clamping part II which can be matched with the inlet of the sewage pipe to realize clamping.

[0020] The airbag blocking device comprises an air compressor, an air pressure gauge, an air pressure tube and the airbag.

[0021] A method for using the sewage pipe plugging system suitable for high water level operation is characterized by comprising the following steps:

[0022] 1) Insert the dredging device into the sewage inspection well, adjust the height of the cabinet in the dredging device so that the rotating cleaning head of the dredging device can be just inserted into the sewage pipe, rotatably mount the fixing ring on the main shaft, and fix it at the wellhead of the inspection well so that the fixing ring can move horizontally relative to the wellhead, and then install the motor at the top of the main shaft;

[0023] 2) Start the motor, the main shaft drives the disc gear through the main shaft gear, and then the rotating shaft rotates to drive the rotating cleaning head to rotate. Under the action of the brush on the surface of the rotating cleaning head, the sediment on the surface of the pipe is scraped off. At the same time, the thread at the tip of the rotating cleaning head rotates to enter the sewage pipe; when the motor reverses, the rotating cleaning head withdraws from the pipe to achieve the purpose of cleaning the inner wall of the pipe;

The present invention uses the dredging device to clean the entrance of the pipeline before the airbag is blocked, ensuring that the airbag can fit tightly with the inner wall of the pipeline when it is expanded.
