[0002] Sewer pipes are an important part of municipal engineering. The quality of sewer pipes is directly related to whether the discharge of domestic sewage and rainwater is rapid and smooth. During the operation of the pipe network system, oily substances and solids in sewage may accumulate in the sewer pipes, which will hinder smooth drainage and require the pipes to be unblocked and cleaned. When cleaning a blocked sewer pipe, since the blockage has already occurred, sewage that cannot be drained away smoothly often remains in the inspection well. The flooding of sewage makes it difficult for maintenance personnel to find the location of the pipe opening, and also affects the smooth operation of maintenance personnel in the well. Therefore, before unblocking and cleaning the pipes, the residual sewage needs to be pumped away. In the prior art, a water pump is used to extract sewage. When impurities such as oil, sand and gravel exist in the sewage, the water pump may be damaged. Utility Model Content

[0033] See also Figures 1 to 3 In the first aspect, the embodiment of the utility model provides a sewer water suction nozzle 1, including a main body 10 and a reversing elbow 20, the main body 10 has an axially through-going water flow channel 11, one end of the water flow channel 11 is defined as a water suction port 12, and the other end is defined as a water spray port 13, and one end of the water flow channel 11 forming the water suction port 12 is a cone with an inner diameter gradually shrinking in the water flow direction; the reversing elbow 20 is arranged on the main body 10, one end of the reversing elbow 20 is accommodated in the water flow channel 11, and the water outlet of the reversing elbow 20 faces the water spray port 13, and the other end of the reversing elbow 20 is used to be connected to a water inlet pipe.

[0034] Compared with the prior art, the sewer water suction nozzle 1 provided by the embodiment of the utility model has the following beneficial effects:

[0035] The sewer suction nozzle 1 provided by the embodiment of the utility model comprises a body 10 and a reversing elbow 20. The body 10 has an axially through water flow channel 11. One side of the water suction port 12 of the water flow channel 11 is tapered for facilitating water suction. The reversing elbow 20 extends into the water flow channel 11 of the body 10, and the water outlet of the reversing elbow 20 faces the water spray port 13. When in use, the water inlet pipe is connected to the water inlet end of the reversing elbow 20, and the water spray port 13 is connected to the outside through the water outlet pipe. The sewer suction nozzle is placed in an inspection well with residual sewage, and the water inlet pipe is connected to a high-pressure water source. High-pressure water is sprayed from the water outlet of the reversing elbow 20 and enters the water flow channel 11, squeezing out the residual air inside, so that the residual sewage in the well is sucked into the water flow channel, and then flows out from the water spray port driven by the high-speed water flow, thereby realizing the operation of sewage extraction. The sewage remaining in the inspection well enters the water flow channel 11 from the water suction port 12, and enters the water outlet pipe from the water outlet 13 together with the water flow sprayed by the reversing elbow 20, and the sewage in the well is discharged to the outside, completing the pumping operation. The utility model uses the reversing elbow 20 to pass high-pressure water into the water flow channel 11 of the body 10, and uses the high-pressure water to drive the sewage in the well to be discharged. The operation is simple, the use is convenient, and the high-pressure water pump will not be damaged.

[0036] In the embodiment of the utility model, the body 10 can be made of metal (such as cast iron, stainless steel) or non-metal (such as plastic, PVC) and can be manufactured by mechanical cutting, casting or 3D printing. The body 10 has a through water flow channel 11 along its own axial direction. The water flow direction is as follows: Figure 3 As shown by the arrow, a water suction port 12 is formed on one side of the body 10, and a water spray port 13 is formed on the other side. When in use, it is necessary to ensure that the water suction port 12 is immersed in water.

[0037] The reversing elbow 20 is used to guide the high-pressure water flow into the water flow channel 11 to form a high-pressure water column, so as to form a suction force to drive the sewage in the well to be ejected from the water outlet 13 along with the high-pressure water column, so as to achieve the purpose of sucking out the sewage. This operation mode has high requirements on the water inlet velocity and flow rate. The faster the flow rate and the larger the flow rate, the greater the suction force generated by the water column. The water inlet end of the reversing elbow 20 is connected to a water source, which can be a high-pressure pump or a high-pressure water pipe.
