Anti-rotation cable-free underwater shooting device for trash rack

Abstract

The invention discloses an anti-rotation cable-free underwater shooting device for a trash rack. The anti-rotation cable-free underwater shooting device is characterized in that a left lifting rope wheel and a right lifting rope wheel are fixed on a lifting shaft; one end of the lifting shaft is connected with a lifting speed reducer, and the other end of the lifting shaft is connected with a lifting shaft bearing; one end of a left lifting steel wire rope and one end of a right lifting steel wire rope are wound on the left lifting rope wheel and the right lifting rope wheel respectively; the other ends of the left and right lifting steel wire ropes are fixed on a square beam; a T-shaped plate with a left movable pulley and a right movable pulley is placed at the middle of the square beam; the lower end of a vertical board of the T-shaped plate is fixed with a waterproof case; a left wheel frame on which a left universal wheel and a left weight bearing wheel are arranged is connected to the left end of the square beam through a left spring and a connecting rotating shaft; a right wheel frame on which a right universal wheel and a right weight bearing wheel are arranged is connected to the right end of the square beam through a right spring and the connecting rotating shaft; a left moving rope and a right moving rope enable the T-shaped plate to be connected with a left moving rope wheel and a right moving rope wheel; the left moving rope wheel is connected with a left moving speed reducer provided with a left moving motor through a left moving shaft; and the right moving rope wheel is connected with a right moving speed reducer provided with a right moving motor through a right moving shaft. According to the technical scheme, the anti-rotation cable-free underwater shooting device for the trash rack is ingenious in structure and can be widely applied to the field of underwater inspection of hydraulic power plants.

Description

[0001] Technical field: [0002] The present invention is mainly a device for underwater photography of a trash rack. [0003] Background technique: [0004] At present, there are many camera devices used for underwater inspection of trash racks, but due to the free rotation of the camera lens, there is a situation that it cannot be positioned and photographed underwater, and it is impossible to record the stable image inspection results of the inspected surface of the trash rack. In addition, the trash racks are about 80 meters underwater, and the signal power cable carried by the camera device was pulled off under its own weight, resulting in the failure of image transmission and loss of control over the camera lens. For this reason, the field of hydroelectric power generation is badly in need of an underwater camera device that can neither rotate freely nor break the cable due to the weight of the signal power cable.
