[0004] The above patented maintenance detection device has a complex structure, a large size, and a large overall weight. It is easy to affect the pipeline body when in use. Although the debris blocking the inside of the pipeline can be crushed, the crushed debris still exists in the pipeline and is easy to adhere to the detection device and affect the use of the camera, which is not conducive to detecting the internal situation of the pipeline.

[0020] 1. Compared with the prior art, the municipal drainage pipeline maintenance detection device is provided with a main pipe, a rotating plate, a rebound mechanism, a horizontal plate, a connecting column, a metal sheet, and an electrode sheet. When in use, the main pipe is placed in the pipe so that the horizontal plate can fit with the upper wall of the pipe, and the fixed column is rotated to adjust the height of the electrode sheet so that the electrode sheet contacts the metal sheet and the circuit is connected. Then, the direction of the main pipe is adjusted to push it into the pipe.

After the height of the main pipe is raised, the distance between the main pipe and the upper wall of the pipe will be shortened, and the upper wall of the pipe will press the horizontal plate to move downward, so that the metal plate moves downward and separates from the electrode sheet. At this time, the current is disconnected, thereby judging whether there is debris accumulation in the pipe, and judging the position of the debris accumulation according to the moving distance of the main pipe.

DETAILED DESCRIPTION

[0028] Reference Figure 1-4 The utility model provides a municipal drainage pipeline maintenance detection device: it includes a main pipe 1, the left end of the main pipe 1 is fixedly connected to a limiting block 2, the limiting block 2 is internally movably connected with a rotating plate 3, the rotating plate 3 can rotate around the limiting block 2, the lower surface of the rotating plate 3 is fixedly connected with a rebound mechanism 4, the rebound mechanism 4 will push the rotating plate 3 to move upward, the rotating plate 3 is fixedly connected to the end away from the main pipe 1 with a horizontal plate 5, the lower surface of the horizontal plate 5 is fixedly connected with a connecting column 6, the bottom of the connecting column 6 is fixedly connected with a metal sheet 7, the outer surface of the main pipe 1 is provided with a threaded hole 8, the internal thread of the threaded hole 8 is connected with a fixing column 9, the inner top of the fixing column 9 is fixedly connected with an electrode sheet 10, the number of the electrode sheets 10 is two, the two electrode sheets 10 are not connected together, when the metal sheet 7 contacts the two electrode sheets 10, the two electrode sheets 10 will be connected, the electrode sheet 10 is fixedly connected with a wire 11, the end of the wire 11 away from the electrode sheet 10 extends to the inside of the main pipe 1, the main pipe is used. 1 is placed in the pipeline so that the horizontal plate 5 can fit with the upper wall of the pipeline, and the fixed column 9 is rotated to adjust the height of the electrode sheet 10 so that the electrode sheet 10 contacts the metal sheet 7, and the circuit is turned on. Then the direction of the main pipe 1 is adjusted, and the main pipe 1 is pushed into the pipeline by the propulsion device. When encountering debris accumulated in the pipeline, the debris will be at the bottom of the main pipe 1, raising the height of the main pipe 1. After the height of the main pipe 1 is raised, the distance between the main pipe 1 and the upper wall of the pipeline will be shortened, and the upper wall of the pipeline will press the horizontal plate 5 to move downward, so that the metal plate 7 moves downward and separates from the electrode sheet 10. At this time, the current is disconnected, the wire 11 is connected to the detection device, and the time when the current is disconnected is recorded. The main pipe 1 continues to move forward. After leaving the debris, the height of the main pipe 1 will drop. At this time, the rebound mechanism 4 pushes the rotating plate 3 to move upward, so that the horizontal plate 5 returns to its original position, and the circuit is reconnected. The detection device records the time when the circuit is connected, thereby judging whether there is debris accumulation in the pipeline, and judging the position of the debris accumulation according to the moving distance of the main pipe.

[0029] The rebound mechanism 4 includes a moving column 401, a spring 402, and a limiting column 403. The moving column 401 is installed on the lower surface of the rotating plate 3, the limiting column 403 is installed on the outer surface of the main pipe 1, and the spring 402 is installed inside the limiting column 403. The end of the moving column 401 away from the rotating plate 3 extends to the inside of the limiting column 403, and the end of the moving column 401 away from the rotating plate 3 is fixedly connected to the top of the spring 402. The inner diameter of the limiting column 403 is larger than the outer diameter of the moving column 401. When the rotating plate 3 moves downward, the moving column 401 can make a certain distance of horizontal displacement in the limiting column 403. After the horizontal plate 5 loses pressure, the spring 402 will rebound, push the rotating plate 3 to deflect upward, and then push the horizontal plate 5 to move upward, so that the metal sheet 7 and the electrode sheet 10 are in contact again.

[0030] A movable groove 12 is provided on the outer surface of the horizontal plate 5, and a rotating shaft 13 is fixedly connected inside the movable groove 12, and the number of rotating shafts 13 is multiple, and the outer surfaces of the multiple rotating shafts 13 are movably connected with rollers 14 to reduce the friction between the horizontal plate 5 and the upper wall of the pipeline, so as to facilitate the movement of the main pipe 1 into the pipeline.

A through hole 17 is provided on the surface of the main pipe 1, and one end of the traction rope 16 away from the fixed block 15 passes through the through hole 17 and extends to the inside of the main pipe 1. By pulling the traction rope 16 backward, the rotating plate 3 can be controlled to rotate downward, thereby reducing the space occupied by the detection device, facilitating the withdrawal of the detection device from the pipeline after the detection is completed, and facilitating the use of the detection device. A diverter block 18 is fixedly connected to the front end of the main pipe 1, and the structure of the diverter block 18 is a conical structure, which facilitates the movement of the main pipe 1 in the pipeline.

[0031] Working principle: When in use, place the main pipe 1 in the pipeline so that the horizontal plate 5 can fit with the upper wall of the pipeline, and rotate the fixed column 9 to adjust the height of the electrode sheet 10 so that the electrode sheet 10 contacts the metal sheet 7, connect the circuit, and then adjust the direction of the main pipe 1 to push it into the pipeline. When encountering debris accumulated in the pipeline, the debris will be at the bottom of the main pipe 1, raising the height of the main pipe 1. After the height of the main pipe 1 is raised, the distance between the main pipe 1 and the upper wall of the pipeline will be shortened, and the upper wall of the pipeline will press the horizontal plate 5 to move downward, so that the metal plate 7 moves downward and separates from the electrode sheet 10. At this time, the current is disconnected, the wire 11 is connected to the detection equipment, and the time when the current is disconnected is recorded. The main pipe 1 continues to move forward. After leaving the debris, the height of the main pipe 1 will drop. At this time, the rebound mechanism 4 pushes the rotating plate 3 to move upward, so that the horizontal plate 5 returns to its original position, and the circuit is reconnected. The detection equipment records the time when the circuit is connected, thereby judging whether there is debris accumulation in the pipeline, and judging the position of the debris accumulation according to the moving distance of the main pipe.
