Embodiment

[0043] ROV submersible, that is, remotely controlled unmanned submersible, is an underwater robot used for underwater observation, inspection and construction. The system generally includes: power propulsion, remote control electronic communication device, black and white or color camera, camera tilting head, user peripheral sensor interface, real-time online display unit, navigation positioning device, automatic helmsman navigation unit, auxiliary lighting and Kevlar Zero-buoyancy towline and other unit parts. Functionality is diverse, and different types of ROVs are used to perform different tasks.

[0044] However, when used for inspection of long tunnels under high-velocity water conditions, the ROV submersible is in an unsteady state, and the detection effect is poor. At the same time, the maneuverability of the ROV submersible is reduced, and it is easy to collide with the tunnel, causing damage to the ROV submersible. In view of this, the present invention proposes a l...

Abstract

The invention discloses a long tunnel flow channel inspection system under a high-flow-velocity flowing water condition. The long tunnel flow channel inspection system under the high-flow-velocity flowing water condition comprises a traction device, an inspection ship, an inspection module and a navigation module. The traction device comprises at least one driver and a traction rope, the driver is fixed on the shore base, one end of the traction rope is connected with the driver, and the other end of the traction rope penetrates through a tunnel and extends out of the tunnel; the inspection ship floats on the flow channel and is connected with the traction rope, so that the inspection ship flows along the traction rope under the action of the driver; the inspection module and the navigation module are both arranged on the inspection ship, the navigation module is in communication connection with the driver so that the inspection ship can flow in the tunnel at a constant speed, and the inspection module inspects the tunnel in the flowing process of the inspection ship. The long tunnel flow channel inspection system under the high-flow-rate flowing water condition can inspect the tunnel under the high-flow-rate flowing water operation condition, full-coverage scanning of the long tunnel is achieved, and the problem that an ROV submersible cannot be used under the high-flow-rate flowing water operation condition is solved.

Description

technical field [0001] The invention belongs to the technical field of inspection equipment, and in particular relates to an inspection system for a long tunnel flow channel under high-speed flowing water conditions. Background technique [0002] A diversion tunnel is a tunnel used for construction diversion purposes. The engineering diversion tunnel has a design safe operation period. If it is in service for a long time, there will be a major safety hazard in the structure of the tunnel body; In order to ensure the integrity of the structure of the diversion tunnel and ensure the diversion safety of the diversion tunnel, the inspection of the diversion tunnel body is a necessary and significant work. [0003] In the past, the inspection of the operation of the diversion tunnel of the dam was completed by submersibles, such as remote power supply and control of ROV submersibles. Under the condition that the water flow rate meets the detection speed of ROV submersibles, long...
