[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In this embodiment, as Figures 1 to 5A municipal pipeline dredging device shown in the figure includes a high-pressure nozzle 1 and a high-pressure water pipe 3. One end of the high-pressure water pipe 3 is connected to the high-pressure nozzle 1, and the other end is connected to a high-pressure water pump. The front part of the high-pressure nozzle 1 is a tapered part 101 for facilitating entry into the pipeline, and the rear part is a cylinder 102. A straight groove 6 is opened in the center of the cylinder 102. There are 4 to 8 through jet holes 4 provided on the side wall of the straight groove 6. The jet holes 4 are inclined backward, and the jet holes 4 are evenly distributed along the circumference. A connecting pipe 2 is installed in the straight groove 6. The rear end of the connecting pipe 2 is detachably connected to the high-pressure water pipe 3. The connecting pipe 2 is in close fit with the straight groove 6. Water passing holes 8 are opened on the side wall of the connecting pipe 2. The water passing holes 8 are evenly distributed in a circle on the connecting pipe 2. The water passing holes 8 correspond to the jet holes 4 one by one. The high-pressure water pipe 3 conveys high-pressure water flow through the connecting pipe 2. The high-pressure water flow sprays outwards from the jet holes 4 through the water passing holes 8, pushing the high-pressure nozzle 1 to move forward. During the forward movement, the high-pressure water flow sprayed backward will scour the silt in the pipeline.

[0021] Jet design: The jet holes 4 are arranged in three circles, namely the front, middle, and rear circles, and the inclination angles of the jet holes 4 in different circles are different. Generally, the inclination angles gradually decrease from the front to the rear in the front, middle, and rear circles. The number of circles of the water passing holes 8 is the same as the number of circles of the jet holes 4, and only one circle of water passing holes 8 is connected to the jet holes 4 each time. This design can adjust the jet direction to meet the dredging requirements of different pipelines.

[0022] Adjustable connection design: A tubular connecting part 103 is provided at the outer circle of the notch of the straight groove 6. External threads are provided on the outer side of the connecting part 103. A retaining ring 9 and a sleeve 5 are provided at the rear part of the connecting pipe 2. The opening at the rear part of the sleeve 5 is smaller than the outer diameter of the retaining ring 9. Internal threads are provided on the sleeve 5. The sleeve 5 can be screwed tightly at the connecting part 103. The retaining ring 9 can be closely attached to the rear end of the connecting part 103. A sealing ring 11 is also provided between the retaining ring 9 and the connecting part 103 to improve the sealing performance of the device and prevent high-pressure water flow from leaking.

[0023] A plurality of clamping grooves 7 are provided on the inner side of the rear end of the connecting part 103. The number of clamping grooves 7 is the same as the number of circles of the jet holes 4. A clamping block 10 matching the clamping grooves 7 is provided on the front side of the retaining ring 9. When the clamping block 10 is inserted into the clamping grooves 7, the connecting pipe 2 can be limited. When the clamping block 10 is inserted into different clamping grooves 7, the jet holes 4 in different circles are communicated with the water passing holes 8. This design can conveniently adjust the working state of the jet holes 4 to meet different dredging requirements.

[0024] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
