Then connect the drainage pipe 6 to the unblocking trolley 1, insert the drainage pipe 6 into the water source, and then the operator controls the unblocking trolley 1 to move in the pipe. The operator can observe the blockage inside the pipe through the handheld computer 5 and control the movement of the unblocking trolley 1. At the same time, the unblocking drill 2 is started to clear the blockage inside the pipe. If the unblocking is not successful, the high-pressure water pump 18 can be started, so that the high-pressure water pump 18 drives the high-pressure water flow to flush the blockage, thereby achieving the purpose of clearing the blockage.

[0059] In summary, compared with existing technologies, this application, by setting up a clearing trolley 1, which works in conjunction with a clearing drill bit 2 to clear blockages inside the pipe, and simultaneously having a high-pressure water pump 18 on one side of the clearing trolley 1, uses the high-pressure water pump 18 to drive water flow to flush away the blockages. The combined effect of the drill bit and the high-pressure water flow effectively clears the blockages inside the pipe, thus achieving the goal of effectively removing blockages. Furthermore, a camera 4 is installed on the top of the clearing trolley 1, allowing observation of the blockage situation inside the pipe and facilitating the monitoring of the clearing process.

[0060] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
