The schematic diagram of the adjustable suction nozzle 4 is shown in FIG. Figure 5 shown.

[0045] The blockage unblocking device 5 is suitable for unblocking the L-type filter suction nozzle 404 when debris is blocking it. The blockage unblocking device 5 includes an electronic pressure gauge 501, a one-way ventilation valve 502 and an air blowing device 503. The electronic pressure gauge 501 is installed at the front section of the drainage channel 304 to measure the pressure in the drainage channel 304; the one-way ventilation valve 502 is used to connect the air blowing device 503 and the drainage channel 304 to control the one-way flow of air from the air blowing device 503 to the drainage channel 304; the upper end of the air blowing device 503 is connected to the atmosphere outside the equipment frame 3 in the pipe, and the lower end of the air blowing device 503 is connected to the one-way ventilation valve 502, which does not work during normal drainage operations.

The schematic diagram of the blockage unblocking device 5 is shown as follows Figure 5 shown.

[0046] The working principle and operation process of the equipment are as follows: A self-draining pipe network detection equipment, whose drainage operations are mainly divided into three types of operations: pipe network detection, drainage of waterlogged sections and removal of debris from suction nozzles. The pipe network detection operation is consistent with the work content of conventional CCTV detection. The main operation content of this equipment is drainage of waterlogged sections and removal of debris from suction nozzles.

[0047] During the drainage operation of the flooded section, when the equipment encounters a flooded section during CCTV inspection, the tablet computer 102 is first used to manually control the liftable wheels 302, and the height of the equipment box 301 is adjusted to prevent the box 301 from being immersed in water. Then, the longitudinal hydraulic device and slider 401, vertical hydraulic device 402, and circumferential rotating device 403 are used to adjust the position of the L-shaped filter nozzle 404 to place it below the water surface. Finally, the drainage program is started, and the accumulated water in the pipe is discharged through the L-shaped filter nozzle 404, corrugated hose 405, drainage channel 304, drainage pipe 201, and drainage hole 104 in turn.

[0048] When the suction nozzle debris is cleared, the blockage dredging device 5 can automatically determine whether the suction nozzle is blocked and automatically clear the debris. Its working principle is as follows: when the drainage operation is performed, the front section of the L-shaped filter suction nozzle 404 is under the water surface, and the electronic pressure gauge 501 detects the air pressure in the drainage channel 304 in real time. By judging whether the front section of the L-shaped filter suction nozzle 404 is blocked by the change in air pressure, the air pressure in the drainage channel 304 can be adjusted according to the drainage situation. When the air pressure in the drainage channel 304 drops sharply by more than 50% of the original air pressure and the drainage pump 305 is idling, it is automatically judged to be an L-shaped filter suction nozzle. The front section of 404 is blocked; at this time, the suction nozzle unblocking program of the tablet computer 102 is activated, the control device turns off the drainage pump 305, and moves the L-shaped filter suction nozzle 404 to the side above the water surface, and starts the blowing device 503 to blow air into the drainage channel 304. When the pressure in the drainage channel 304 increases and then decreases and stabilizes to atmospheric pressure, it is determined that the front section of the L-shaped filter suction nozzle 404 is not blocked. Then, the L-shaped filter suction nozzle 404 is moved below the water surface and the blowing device 503 stops blowing. The suction nozzle unblocking program of the tablet computer 102 is closed, and the control device starts the drainage pump 305 to continue the drainage operation.

[0049] This patent proposes a self-draining pipe network detection device, which consists of an external well device 1, a connecting device 2, an internal pipe equipment frame 3, an adjustable suction nozzle 4, and a blockage clearing device 5. It can realize drainage detection in the water-accumulated pipe network sections of drainage pipes 6 and inspection wells 7.
