Connection flanges are arranged at both ends of the pipe body 1, and the connection flange of one pipe body 1 is connected to the connection flange of another pipe body 1.

[0026] The crushing mechanism 2, the delivery mechanism 3 and the spraying mechanism 4 can be installed on the middle section of the pipeline body 1 or other required pipeline bodies 1. The structure of the pipeline body 1 where these mechanisms need to be installed is as follows: at least one first hole 11, at least one second hole 12 and at least one third hole 13 are provided on the side wall of the pipeline body 1.

[0027] In this embodiment, there are a plurality of first holes 11 arranged at intervals along the axial direction of the pipe body 1 , there is one second hole 12 , and three third holes 13 are arranged along the radial direction of the pipe body 1 .

[0028] like Figure 1 , Figure 2 As shown, the crushing mechanism 2 includes a motor 21, a rotating shaft 22, a blade 23 and a sealing sleeve 24. The crushing mechanism 2 can be installed during the cleaning work, or it can be installed in one or more of them all the time, and the remaining first holes 11 are provided with plugs to achieve sealing.

[0029] The motor 21 is mounted on the outer wall of the pipe body 1, and one end of the rotating shaft 22 passes through the first hole 11 and is connected to the motor shaft of the motor 21. A plurality of grooves 221 are arranged in the axial direction of the rotating shaft 22. A blade 23 is hinged in each of the grooves 221. The rotating shaft 22 rotates so that the blade 23 forms a first position and a second position. In the first position, the blade 23 is parallel to the axis of the rotating shaft 22, and in the second position, the blade 23 forms an angle with the axis of the rotating shaft 22.

[0030] If the crushing mechanism 2 is installed during cleaning, one end of the bottom of the rotating shaft 22 (away from the motor 21) is a suspended structure (such as Figure 2 As shown), the end of the rotating shaft 22 close to the motor 21 is installed in the first hole 11 through a sealing sleeve 24.

[0031] If the crushing mechanism 2 is selected to be installed straight, the end of the rotating shaft 22 away from the motor 21 is rotatably connected to the side wall of the pipeline body 1 (bearings can be used), that is, both ends of the rotating shaft 22 need to be connected to resist the impact force of the water flow.

[0032] When in use, the motor 21 needs to be powered on, the motor 21 is started, the shaft 22 is driven to rotate, and the blade 23 forms a second position under the action of centrifugal force, so that the blade 23 can contact and cut the impurities inside the pipe body 1 until the large hard blocks are chopped up. If the crushing mechanism 2 needs to be replaced or removed, it can be pulled out from the motor 21 end.

[0033] like Figure 1 , Figure 3As shown, the delivery mechanism 3 includes a delivery port 31 , a box body 32 , a capping mechanism 33 , a screw cover 34 , a first connecting pipe 35 , a guide plate 36 and a slide groove 37 .

[0034] The box body 32 is a rectangular box, and a cavity for placing the pipe dredging agent is provided inside. The box body 32 is detachably connected to the outer wall of the pipe body 1 by fasteners such as bolts. An opening is provided on the top of the box body 32, and a screw cover 34 is provided on the opening. When the screw cover 34 is opened, the pipe dredging agent can be put into the cavity from the opening, and the screw cover 34 is usually covered.

[0036] A guide plate 36 is provided on one side wall of the box body 32 , and an upper end of the guide plate 36 is provided with an inclined surface inclined toward the delivery port 31 , and the inclined surface is used to guide the medicine in the box body 32 to the upper end of the sealing plate 331 .

[0037] The guide plate 36 is arranged near the bottom, and a slide groove 37 is formed between the guide plate 36 and the inner bottom surface of the box body 32. The cover mechanism 33 includes a cover plate 331, a pull rod 332 and a spring 333. The pull rod 332 is arranged in the slide groove 37, and one end of the pull rod 332 extends out of the box body 32, and the other end of the pull rod 332 is connected to the cover plate 331, and the cover plate 331 is arranged near the delivery port 31, and the spring 333 is sleeved on the pull rod 332, and the spring 333 abuts against the cover plate 331 and the box body 32 respectively.

[0039] When the pull rod 332 is pulled outside the box body 32, the sealing plate 331 is Figure 3 The guide plate 36 is moved rightward in the direction shown, so that the delivery port 31 is opened and the spring 333 is compressed. At this time, the medicine inside the box body 32 enters the pipeline body 1 from the delivery port 31 and the first connecting pipe 35, so that the medicine reacts with impurities. When the pull rod 332 is released, under the action of the spring 333, the sealing plate 331 moves leftward and re-seals the delivery port 31. The guide plate 36 is provided with a sharp corner 361 at one end facing the sealing plate 331. When the sealing plate 331 moves rightward, the sharp corner 361 pushes the medicine on the sealing plate 331 to the left to concentrate it at the delivery port 31.

When the external water source is turned on, water passes through the water inlet 41, the first flow channel, the second connecting pipe 43, the second flow channel, the nozzle 46 in sequence, and is finally sprayed out from the water spray port 42 to clean the impurities in the pipeline body 1.

[0044] The motor 21, the box body 32 and the water inlet 41 on the fixing ring 44 need to be provided with protective devices to avoid damage due to pressure. In addition, when cleaning is not required, the crushing mechanism 2 and the delivery mechanism 3 can also be removed, and the first hole 11 and the second hole 12 can be sealed with plugs. For convenience, the spray mechanism 4 can be processed together with the pipeline body 1 and will not be disassembled later, but a plug needs to be provided at the water inlet 41 of the spray mechanism 4.
