Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering facilities technology, specifically relating to a wall-mounted sewage pipe with a cleaning structure. Background Technology

[0002] To prevent sewage from being directly discharged into rivers and polluting the water quality, intercepting wells and sewage pipes are often built along one side of the river to intercept sewage and transport it to a sewage treatment plant for centralized treatment. During the interception process, houses built right next to the riverbank are encountered. These houses have sewage pipes extending directly into the river through the embankment, allowing domestic sewage to flow directly into the water. Due to space constraints, it's impossible to build intercepting wells between the houses and the river to intercept the sewage. Therefore, intercepting sewage pipes are usually installed on the riverbank to intercept domestic sewage discharged by residents, preventing direct discharge into the river and pollution of the water quality.

[0003] However, after the sewage pipe is installed on the wall, due to the small pipe diameter and the inability to install inspection wells to dredge the pipe, sludge will accumulate at the bottom of the pipe after a long period of operation, the flow cross-section will become smaller, and in severe cases, the pipe will become blocked. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a wall-mounted sewage pipe with a cleaning structure, which can use the potential energy of the upstream water to hydraulically dredge the wall-mounted sewage pipe, prevent the pipe from being silted up and blocked, and facilitate the daily management and maintenance of sewage pipes.

[0005] The technical solution adopted by this utility model is as follows: A wall-mounted sewage pipe with a clearing structure includes a wall-mounted sewage pipe laid along the embankment, and a clearing structure is set at certain intervals on the wall-mounted sewage pipe. The clearing structure includes a slanted tee set on the wall-mounted sewage pipe. One end of the slanted branch of the tee is connected to the bottom of a water storage tank set above the wall-mounted sewage pipe through a connecting pipe. The slanted branch of the tee is inclined to the upstream side of the wall-mounted sewage pipe. A valve is set at the outlet of the slanted tee on the wall-mounted sewage pipe. An air bladder is set inside the water storage tank. An upward-facing tank opening is set at the top of the water storage tank. The air bladder opening is attached to the upper part of the tank opening and is fixedly connected to the tank opening through a flange blind plate and multiple bolts to prevent air leakage. The bottom of the valve core for replenishing air to the air bladder penetrates through the flange blind plate and extends into the air bladder. The top of the valve core is exposed to the air.

[0006] Furthermore, a valve support is provided at the bottom of the valve, and the valve support is fixed to the dike.

[0007] Furthermore, a water tank support is provided at the bottom of the water storage tank, and the water tank support is fixed to the dike.

[0008] Furthermore, the wall-mounted sewage pipe has a diameter of DN200 to DN300 and is made of HDPE or UPVC.

[0009] Furthermore, the angle of the inclined branch pipe of the oblique tee is 45 degrees, and the material is the same as that of the wall-mounted sewage pipe.

[0010] Furthermore, the diameter of the connecting pipe is DN50 to DN100, and the material is the same as that of the wall-mounted sewage pipe.

[0011] Furthermore, the airbag is made of rubber.

[0012] Furthermore, the tank opening is in the form of a flange, the same size as a flange blind plate.

[0013] This utility model has the following advantages:

[0014] 1. Utilize the potential energy of the upstream water to hydraulically dredge the wall-mounted sewage pipe, prevent pipe siltation and blockage, and facilitate the daily management and maintenance of the sewage pipe.

[0015] 2. When the valve is closed, the upstream water has potential energy, which squeezes the air bladder in the water storage tank and converts the potential energy into pressure energy for storage. When the valve is opened to release water, the pressure energy of the air bladder is released and converted into the kinetic energy of the water flow, providing greater energy for hydraulic dredging and resulting in better dredging effect.

[0016] 3. When the valve is opened to release water, the oblique impact of the water flow can directly act on the silt deposited at the bottom of the pipe, resulting in a better unblocking effect.

[0017] 4. This device is simple to operate, highly practical, and does not require electricity or other energy sources, saving time and effort. In actual engineering projects, this device can be installed at certain intervals on the wall-mounted sewage pipe to achieve hydraulic cleaning of the entire sewage pipe. Attached Figure Description

An airbag 71 is set inside the water storage tank 7. An upward-facing tank opening 72 is set at the top of the water storage tank 7. The airbag opening of the airbag 71 is attached to the upper part of the tank opening 72 and is fixedly connected to the tank opening 72 through a flange blind plate 73 and multiple bolts 74.

[0033] To facilitate understanding of the present invention, the implementation process of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This utility model relates to a wall-mounted sewage pipe with a cleaning structure. After the cleaning structure is installed, the air bladder 71 is first inflated through the air valve core 75, causing the air bladder 71 to expand. Sewage flows in the wall-mounted sewage pipe 1. Due to the impurities carried by the sewage, sludge gradually settles at the bottom of the pipe after a period of time, affecting the flow cross-section. At this time, valve 2 is closed, and the sewage cannot flow normally. Due to the potential energy of the upstream water, the water flow in front of valve 2 quickly gathers and enters the water storage tank 7 through the oblique tee 5 and the connecting pipe 6. The water level in the water storage tank 7 rises rapidly, squeezing the water in the water storage tank 7. Airbag 71, in a compressed state, converts potential energy into pressure energy and stores it. Opening valve 2 releases the pressure energy of airbag 71, converting it into the kinetic energy of the water flow, providing greater energy for hydraulic dredging. The water flows through connecting pipe 6 and oblique tee 5 into the wall-mounted sewage pipe 1. Due to the oblique entry of the water, the silt deposited at the bottom of the pipe can be directly flushed downstream, preventing further deposition. To ensure the stability of valve 2 and water tank 7, valve support 3 is installed at the bottom of valve 2, and water tank support 8 is installed at the bottom of water tank 7. Both supports are fixed to the dike 4. By installing dredging structures at intervals along the entire length of the wall-mounted sewage pipe 1, dredging can be performed section by section from downstream to upstream, achieving hydraulic dredging of the entire sewage pipe.

[0035] The working process of this utility model is as follows: Under normal working conditions, the airbag 71 is inflated after being inflated by the valve core 75. The sewage flows in the wall-mounted sewage pipe 1 in a non-full flow state. After a period of time, sludge gradually settles at the bottom of the pipe. At this time, the valve 2 is closed. Due to the potential energy of the upstream water, the water flow in front of the valve 2 quickly gathers and enters the water storage tank 7 through the oblique tee 5 and the connecting pipe 6. The water level in the water storage tank 7 rises rapidly and squeezes the airbag 71 in the water storage tank 7. The airbag 71 is in a compressed state, converting potential energy into pressure energy and storing it. When the valve 2 is opened, the pressure energy of the airbag 71 is released and converted into the kinetic energy of the water flow. The water flow enters the wall-mounted sewage pipe 1 through the connecting pipe 6 and the oblique tee 5. Due to the oblique entry of the water flow, the sludge deposited at the bottom of the pipe can be directly flushed downstream to prevent it from continuing to settle at the bottom of the pipe. This cleaning structure is set at certain intervals along the entire length of the wall-mounted sewage pipe 1. The sewage pipe is cleaned section by section from downstream to upstream, so that the entire sewage pipe can be hydraulically cleaned.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
