[0024] The adjusting assembly 200 in this embodiment is installed on the sewage suction tank 110, and can be adjusted to drive the sewage suction assembly 300 and the flushing assembly 400 to move.

[0025] like Figure 2 As shown, in one embodiment, the adjustment assembly 200 includes a turntable 210, a telescopic arm 220 and a driving member. The turntable 210 is disposed on the top of the sewage suction tank 110 and is rotatably connected to the sewage suction tank 110.

The discharge end of the sewage suction pump is rotated and sealed with the sewage suction tank 110 via a rotary joint 310. The other end of the sewage suction pipe is arranged around the turntable 210 and is slidably connected with the telescopic arm 220.

[0030] In order to facilitate the winding of the sewage suction pipe, in one embodiment, a winding member 221 can be provided on the telescopic arm 220, and the winding member 221 includes two winding rollers and two winding motors arranged opposite to each other. The two winding rollers are connected to the telescopic arm 220, and a winding gap is formed between the two winding rollers. The sewage suction pipe is arranged to pass through the winding gap. The output ends of the two winding motors are respectively connected to the two winding rollers to drive the two winding rollers to rotate in opposite directions, thereby realizing the function of winding up the sewage suction pipe.

[0031] At the same time, a guide 222 for the sewage suction pipe to pass through can be provided at one end of the sliding arm away from the fixed arm to limit the direction of the sewage suction end of the sewage suction pipe.

[0032] The flushing assembly 400 in this embodiment includes a high-pressure water pump 410 and a flushing pipe 420. The high-pressure water pump 410 is installed on the sewage suction tank 110. One end of the flushing pipe 420 is connected to an external water source via the high-pressure water pump 410, and the other end of the flushing pipe 420 is arranged around the turntable 210 and is slidably connected to the telescopic arm 220.

[0033] like Figure 3 As shown, in one embodiment, the flushing assembly 400 also includes a plurality of first guide members 421 having guide gaps, the plurality of first guide members 421 are sequentially arranged along the length direction of the telescopic arm 220, and the flushing pipe 420 is sequentially arranged to pass through the guide gaps of the plurality of first guide members 421.

[0034] In order to avoid interference between the turntable 210 and the flushing pipe 420 during rotation, in one embodiment, it also includes a plurality of second guide members installed at the bottom of the turntable 210, and the plurality of second guide members are evenly arranged along the circumference of the turntable 210.

If there is stubborn dirt formed due to factors such as compaction, the stubborn dirt can be crushed by the dirt removal end 430, and the flushing component 400 can be opened to use a high-pressure water source to separate and decompose the stubborn dirt. Finally, the dirt is drawn into the suction tank 110 by the suction end of the suction component 300 to complete the treatment of the stubborn dirt in the pollution source.
