As shown in fig. 7, the rotating assembly 400 in this embodiment includes a bracket 410 and a rotating member, the bracket 410 is fixedly disposed on the top of the sewage suction truck, the rotating member is fixedly disposed on the bracket 410, and an output end of the rotating member is connected to the roller pipe assembly for driving the roller pipe assembly to rotate.

The rotating part comprises a rotating disc 430 and a connecting part 440, the rotating disc 430 is rotatably connected with the support 410, the rotating disc 430 is fixedly connected with the pipe coiling assembly, an annular rack is arranged on the rotating disc 430, and the output end of the connecting part 440 is connected with the annular rack so as to drive the annular rack to rotate.

The base body in this embodiment includes a vehicle body 600 and a dirt storage tank 500, the dirt storage tank 500 is arranged on the vehicle body 600, the pipe length adjusting assembly 200 is connected with the dirt storage tank 500 through the rotating assembly 400, and the dirt suction pipe 100 is communicated with the dirt storage tank 500 through the rotary joint 420.

The working process is as follows: if the operation place is inconvenient or even the vehicle cannot be parked, the vehicle body 600 is opened to the position nearest to the operation place and can be parked out, the adjusting arm 300 is enabled to point to the operation place through the rotating assembly 400, the pipe length adjusting assembly 200 is started, the sewage suction pipe 100 is drawn out until the sewage inlet of the sewage suction pipe 100 is moved to the position above the sewage source, the adjusting arm 300 is adjusted, the sewage inlet of the sewage suction pipe 100 is inserted into the sewage source, and the pump on the sewage storage tank 500 is started to draw the sewage source; if the working position has a plurality of working points, the vehicle is driven to the middle of the plurality of working points, the adjusting arm 300 is enabled to sequentially point to the plurality of working positions through the rotating assembly 400, and the steps are repeated to finish the dirt pumping work of the plurality of working points.

Compared with the prior art: through setting up sewage suction pipe 100, long adjusting part 200 of pipe, regulating arm 300, runner assembly 400 and base member, if operation department is inconvenient even when unable parking, because long adjusting part 200 of pipe can rolling sewage suction pipe 100, the device's sewage suction pipe 100 is longer, can use in long distance operation, carry out the sewage suction operation at the distal end, thereby solve above-mentioned problem, if there are many operating points in operation department, be fixed in on the base member through runner assembly 400, the output and the long adjusting part 200 of pipe of runner assembly 400 are connected, be used for driving long adjusting part 200 of pipe to rotate to the optional position in the horizontal plane, can stop the car to a department, carry out extraction work in proper order to a plurality of operating points, this sewage suction device working range is wide, and is easy to operate, but wide application in various complicated operation environments.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
