Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage pipeline cleaning equipment, and more specifically to a cleaning nozzle applied to municipal drainage pipelines. Background Art

[0002] Municipal drainage pipes refer to the pipe systems used to discharge rainwater, wastewater and sewage in cities. These pipe systems are usually composed of underground pipes, sewers, rainwater pipes, etc., and are responsible for discharging domestic sewage, rainwater and industrial wastewater to sewage treatment plants or directly into rivers, lakes and other water bodies. The design and construction of municipal drainage pipes are very important. They play a vital role in urban environmental sanitation, residents' quality of life and water resource protection. Through the reasonable planning and construction of municipal drainage pipe systems, urban waterlogging, sewage pollution and other problems can be effectively avoided, ensuring a clean and healthy environment in the city.

[0003] After long-term use, the existing municipal drainage pipes may cause plant roots to grow into the pipes, and the inner walls of the pipes will also be adhered to more debris in the sewage. As the plant roots grow and the debris accumulates, the drainage pipes may be blocked and cannot be used normally. Therefore, it is necessary to manually clean the pipes regularly. The transmission cleaning method generally adopts high-pressure flushing, chemical cleaning, pipeline renovation, etc. Among them, high-pressure flushing can only clean loosely adhered impurities, but cannot deal with firmly adhered impurities and plant roots. Chemical cleaning will produce a large amount of toxic substances and cause environmental pollution. Although the pipeline renovation method can deal with the problems of impurities inside the pipeline and plant roots, it has a large amount of work and high cost expenditure, which is very inconvenient.

The drainage thread grooves 601 facilitate the rotation of the rotating shell 6 under the drive of the high-pressure water flow.

[0028] Reference Figure 6 As shown, the support shaft 10 includes a cylindrical shaft 1001, a first blocking piece 1002 is provided on the surface of the cylindrical shaft 1001, a connecting column 1003 is fixedly connected to the first blocking piece 1002 on the side away from the cylindrical shaft 1001, a second blocking piece 1004 is provided on the surface of the cylindrical shaft 1001 away from the first blocking piece 1002, a first gasket 11 is movably sleeved on the surface of the cylindrical shaft 1001 away from the first blocking piece 1002 and the second blocking piece 1004, and a second gasket 12 is movably sleeved on the surface of the cylindrical shaft 1001 at the position where the first gasket 11 is sleeved.

[0030] The working principle of the utility model is as follows: first, when using it, the limit block 3 corresponding to the diameter of the pipe is installed inside the limit groove 201 provided on the limit bracket 2, and then the high-pressure water gun is rotated and installed inside the threaded connection hole 501 provided on the connecting head 5. At this time, when the high-pressure water gun is installed, the gravity of the water gun drives the rotating shell 6 movably connected to the other side of the connecting head 5 so that the cleaning head 7 and the dredging head 8 are level with the ground, and then the cleaning nozzle is placed as a whole into the pipe to be cleaned. At this time, the high-pressure water gun is turned on, so that water enters the water outlet trough 504 through the threaded connection hole 501, and is discharged through the water outlet trough 504 to the drainage thread groove 601 provided on the surface of the rotating shell 6. At this time, the drainage thread The groove 601 rotates under the action of the high-pressure water flow, causing the rotating shell 6 to rotate on the surface of the support shaft 10. At this time, the rotation of the rotating shell 6 drives the cleaning head 7 and the unblocking head 8 to rotate. Then, when the cleaning head 7 rotates, the cutting chain 9 is swung and unfolded due to the centrifugal force. At this time, the high-pressure water gun is slowly pushed to allow the cleaning nozzle to enter the inside of the pipe. At this time, the unblocking head 8 cleans the loose impurities inside the pipe, and then the rotation of the cutting chain 9 causes the cutting head 901 to cut the impurities and plant roots that are more firmly adhered to the inner wall of the pipe. Then, the impurities cleaned by the unblocking teeth 801 and the cutting head 901 are flushed by the high-pressure water flow flowing out of the drainage thread groove 601 to clean the inner wall of the pipe.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
