[0026] Pipeline desilting is an important task in the maintenance of urban drainage systems. One of the high-pressure desilting methods is to use a high-pressure hose of a high-pressure cleaning equipment to extend into the underground pipe. The impact force and flow rate of the high-pressure water flow break up and wash away the silt, thereby achieving the desilting work of the pipe.

[0027] However, in the process of inserting the high-pressure hose into the manhole pipe, the high-pressure hose is easily rubbed by sharp pipe joints, etc., causing damage to the hose wall and leakage, affecting the normal dredging operation, and causing delays in work, time and effort.

[0028] The utility model provides a guide protection device 10 and a pipeline desilting device 100, which are intended to protect a high-pressure hose from leakage due to wear, extend the service life of the high-pressure hose, and ensure the reliability of desilting operations.

[0029] See also Figure 1 and Figure 2In one embodiment of the present utility model, the guide protection device 10 is used to protect the high-pressure hose 20. One end of the high-pressure hose 20 is located at the wellhead of the manhole pipe, and the other end penetrates into the bottom of the manhole pipe. The guide protection device 10 includes a fixing frame 1 and a connecting member 2. The fixing frame 1 is used to be installed at the bottom of the manhole pipe. The fixing frame 1 has a guide port 11. The edge of the guide port 11 is an arc surface or a flexible material. The other end of the high-pressure hose 20 passes through the guide port 11; one end of the connecting member 2 is connected to the side of the fixing frame 1 away from the bottom of the manhole pipe, and the other end of the connecting member 2 is used to be exposed at the wellhead of the manhole pipe.

[0030] In this embodiment, the fixing frame 1 can be made of a metal frame material, such as an aluminum alloy profile, which is lightweight, durable, and relatively strong. The metal material has a certain degree of self-lubrication, which reduces friction on the high-pressure hose 20. The connecting member 2 can be made of a metal material, such as an aluminum alloy. One end of the connecting member 2 is connected to the fixing frame 1, which can be welded, threaded, or plugged in. The fixing frame 1 is enclosed by a frame to form a guide opening 11. The edge of the guide opening 11 can be set as an arc surface or coated with a flexible material to reduce the friction between the edge of the guide opening 11 and the high-pressure hose 20, thereby extending the service life of the high-pressure hose 20 and ensuring the reliability and stability of the dredging operation.

[0031] The guide protection device 10 proposed in the technical solution of the present invention includes a fixing frame 1 and a connecting member 2. The fixing frame 1 has a guide port 11. One end of the high-pressure hose 20 passes through the guide port 11 and is located at the bottom of the manhole pipe. The other end of the high-pressure hose 20 is located at the wellhead of the manhole pipe and is used to connect to a high-pressure water source. One side of the fixing frame 1 is connected to the bottom of the manhole pipe, and the other side is connected to one end of the connecting member 2.

When the high-pressure hose 20 moves forward, the guide roller 3 will rotate, converting the sliding friction between the high-pressure hose 20 and the fixed frame 1 into rolling friction between the high-pressure hose 20 and the guide roller 3, thereby reducing the friction force on the high-pressure hose 20, further extending the service life of the high-pressure hose 20, and ensuring the reliability and stability of the dredging operation.

[0034] In the embodiment of the present invention, there are multiple guide rollers 3 , and the multiple guide rollers 3 are arranged around the circumference of the guide opening 11 .

[0035] In this embodiment, a plurality of guide rollers 3 are provided around the guide opening 11, which can ensure that the high-pressure hose 20 can contact the guide roller 3 regardless of which side of the guide opening 11 it abuts, thereby further reducing the friction force on the high-pressure hose 20, extending the service life of the high-pressure hose 20, and ensuring the reliability and stability of the dredging operation.

[0036] In the embodiment of the present invention, the guide opening 11 is rectangular, two guide rollers 3 are arranged at two opposite inner edges of the guide opening 11 along the horizontal direction, and the other two guide rollers 3 are arranged at two opposite outer edges of the guide opening 11 along the vertical direction.
