There is a motor fixing cavity in the base 6, and the driving motor is installed in the motor fixing cavity and is drivingly connected to the rotating shaft 7; The water cavity 4 is installed on the base 6. On the side of the water cavity 4 facing the camera 3, there is a water outlet, and the cleaning cotton 5 covers the water outlet of the water cavity 4 and is located on the rotation path of the camera 3.

[0035] The video recording device in the pipeline adopting this solution can be directly placed in the pipeline. By controlling the rotating motor to drive the gear 202 and the top semi-circular rack 1, the top semi-circular rack 1 gradually extends until it abuts against the inner wall of the pipeline, and achieves preliminary fixation based on the tension force. At this time, the video recording of the pipeline environment can be continuously carried out through the camera module.

[0036] Since the environment of the inner wall of the pipeline is poor and it is easy to contaminate the lens, in this solution, the driving motor can drive the whole camera 3 to rotate.

[0043] The top semi-circular rack 1 needs to have a certain elastic deformation ability, so it needs to be made of a material with a certain toughness and corrosion resistance, and can be selected as iron material, stainless steel material, etc. In this embodiment, both the top semi-circular rack 1 and the bottom semi-circular seat 2 are made of iron material, and the top semi-circular rack 1 is of iron sheet structure.

[0044] The driving motor is located in the base 6 at the bottom, and drives the camera 3 to rotate on the horizontal plane through the rotating shaft 7.

[0045] The camera 3 faces the liquid flow direction of the pipeline, and the water outlet of the water chamber 4 is located at the rear side of the camera 3.
