Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe network detection, and particularly relates to a device for drainage pipe network detection. Background Technique

[0002] Common devices for drainage pipe network detection are "drain pipe detection cameras" or "drain pipe detection robots". These devices are usually equipped with cameras, lighting equipment and some sensors, and can be used to detect the internal conditions of drainage pipes. The drain pipe detection camera can enter the drainage pipe through the pipe entrance or other access points, and then move along the inside of the pipe while transmitting the images inside the pipe to the display screen in real time. With the help of these cameras, operators can detect damages, blockages, rust, corrosion or other problems inside the drainage pipe, so as to carry out repairs and cleaning in time. The drain pipe detection robot usually has a motion system and can move freely inside the pipe, and is equipped with devices such as cameras to achieve a full-range detection of the internal conditions of the drainage pipe. These devices can improve the accuracy and efficiency of drainage pipe detection, help to detect and solve drainage pipe problems in time, and ensure the normal operation of the drainage system.

When in use, the car is placed into the pipe through a rope, and then the car walks inside the pipe, and the inside of the pipe is detected through the images transmitted by the camera. However, there is often a lot of silt accumulated inside the pipe. When the car walks, it is easy to get stuck in the silt and is also prone to roll over, which affects the normal walking of the car and the detection effect of the drain pipe, and the practicability is not strong.
