[0002] The sewage cleaning and suction truck is equipped with two tanks: a clean water tank and a sewage tank. When cleaning the sewer pipe, the sewage in the sewer pipe can be stored and transported through the sewage tank, and then connected to the clean water tank through a high-pressure water pipe, and the clean water in the clean water tank is used to clean the sewer pipe. After the cleaning is completed, the high-pressure water pipe is reeled in and placed at the tail of the tank through a reeling device. However, the reeling device directly reels the high-pressure water pipe in the process of reeling in the high-pressure water pipe, and does not adjust the tightness of the high-pressure water pipe when reeling in. This will cause the high-pressure water pipe to be too loose when reeling in, which may easily lead to a reduction in the storage space of the reeling device, and it may also easily lead to the high-pressure water pipe being squeezed and deformed due to being too tight when reeling in.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-2 A cleaning and suction truck with a winding device includes a frame 1 and a tank body 2. A winding device 21 for winding a high-pressure water pipe is provided on the surface of the tank body 2. A water pipe tensioning assembly 22 is provided on the surface of the tank body 2. The water pipe tensioning assembly 22 includes a tensioning member 23 that can contact with the high-pressure water pipe and can be away from the high-pressure water pipe. The water pipe tensioning assembly contacts the high-pressure water pipe during winding, so that the tightness of the high-pressure water pipe during winding is appropriate, thereby avoiding deformation of the high-pressure water pipe due to being too tight when winding or reducing the storage space of the winding device due to being too loose.

[0023] In some embodiments, the tensioning member 23 is a tensioning wheel 24 that can be translated left and right. The water pipe tensioning assembly 22 also includes guide rails 25 provided at both ends of the tensioning wheel 24. Both ends of the tensioning wheel 24 are rotatably connected to screws 26 through bearing seats. One end of the screw 26 passes through the guide rail 25. One end of the screw 26 is threadedly engaged with a nut 27. The screw 26 can be locked in the current position of the guide rail 25 through the nut 27, so that the tensioning wheel 24 can abut against the high-pressure water pipe, ensuring the tightness when the winding device 21 winds up the high-pressure water pipe. A storage box 28 is installed on the surface of the tank body 2. The winding device 21 and the tensioning member 23 are both located inside the storage box 28, and one end of the guide rail 25 is connected to the inner wall of the storage box 28. The storage box 28 can prevent the high-pressure water pipe from being directly exposed to sunlight, thereby slowing down the aging speed of the high-pressure water pipe.

[0024] At the same time, a cleaning assembly 3 for cleaning the surface of the high-pressure water pipe is provided inside the storage box 25. The cleaning assembly includes a cleaning brush 31 for cleaning dirt on the surface of the high-pressure water pipe. A first mounting block 32 and a second mounting block 33 for mounting the cleaning brush 31 are provided inside the storage box 28. The cleaning brushes 31 are respectively mounted on symmetrical sides of the first mounting block 32 and the second mounting block 33 so that a cleaning area 34 is formed between the first mounting block 32 and the second mounting block 33 for the high-pressure water pipe to pass through. When the high-pressure water pipe is reeled in, the high-pressure water pipe will pass into the cleaning area 34. When the high-pressure water pipe passes through the cleaning area 34, it will contact the cleaning brush 31, and the cleaning brush 31 can sweep away dirt on the surface of the high-pressure water pipe, thereby achieving the purpose of cleaning the high-pressure water pipe.

[0025] Furthermore, one side of the storage box 28 is connected to a limit block 4 for limiting the high-pressure water pipe head. The limit block 4 is provided with a through hole 41 that cooperates with the high-pressure water pipe. When the high-pressure water pipe is reeled in, the high-pressure water pipe will enter the storage box 25 through the through hole 41, and the limit block 4 can prevent the high-pressure water pipe head from entering the storage box 28.

[0026] In some embodiments, a sewage outlet 5 for discharging sewage is provided on the surface of the tank body 2, and a sealing cover is installed on the surface of the sewage outlet 5. A plurality of sewage valves 51 are also provided on the surface of the tank body 2, and a sewage suction pipe 52 is provided on one side of the tank body 2. When the sewage in the tank body 2 is to be discharged, most of the sewage in the tank body 2 is first discharged through the sewage valve 51, and then the sealing cover on the sewage outlet 5 is opened so that the remaining sewage can flow out from the sewage outlet 5.

[0027] The specific work flow to adjust the tightness of the high-pressure water pipe is as follows:

[0028] The nut 27 is rotated in the opposite direction so that the nut 27 starts to move away from the guide rail 25. After the nut 27 moves, it cannot lock the tensioning wheel 24 in its current position, so that the tensioning wheel 24 can start to move left and right along the guide rail 25 through the movable connection between the screw 26 and the guide rail 25. The tensioning wheel 24 can gradually tighten the tightness of the high-pressure water hose when it is reeled in during the left movement, and loosen the tightness of the high-pressure water hose when it is reeled in during the right movement, making the reeling of the high-pressure water hose loose. After adjusting the tightness through the tensioning wheel 24, the nut 27 can be rotated forward to move the nut 27 in the direction of the guide rail 25. The nut 27 will contact the guide rail 25 when moving, so that the nut 27 can lock the tensioning wheel 24 in its current position, ensuring that the tightness of the high-pressure water hose will not change when it is reeled in.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
