Device for detecting range and depth of underwater scouring pit and using method

Abstract

The invention relates to a device for detecting range and depth of an underwater scouring pit. The device comprises a fixed frame and a main control box, wherein the main control box is positioned inthe fixed frame; a first pusher, a second pusher and a third pusher are arranged on the fixed frame and are electrically connected with the main control box; the movement direction between every two of the first pusher, the second pusher and the third pusher are mutually arranged in a vertical way; a depth sensor and a positioner are arranged at the bottom part of the fixed frame, and are connected with the main control box through wires. Compared with the prior art, the device has the advantages that the weight of the whole detection device can be mutually offset by a buoyancy plate, so as toreach the balance effect, and effectively improve the operation flexibility of the underwater detection device in the floating and diving process; the depth sensor and the positioner are used for collecting data, the movement range of the detection device along the boundary of the scouring pit under water and the corresponding depth are recorded in real time, and an underwater terrain map can bequickly generated in the later period.

Description

technical field [0001] The invention belongs to the technical field of underwater detection, and in particular relates to a detection device and a use method for the range and depth of an underwater flushing pit. Background technique [0002] With the rapid development of my country's marine and water conservancy projects, the inspection of its ports and underwater dams has gradually received more attention, especially during the flood control process of the dam, the river downstream of the dam will inevitably be impacted by the water flow, resulting in large-scale flooding. If the pits are not inspected and repaired in time, the safety of the dam will be potentially threatened. At present, most of the underwater inspection projects use the tube-supplied air light diving method for underwater inspection. Divers are equipped with tube-supplied air diving equipment, underwater lighting equipment, underwater cameras, diving phones, and underwater measurement tools. The lower ca...

Problems solved by technology

At present, most of the underwater inspection projects use the tube-supplied air light diving method for underwater inspection. Divers are equipped with tube-supplied air diving equipment, underwater lighting equipment, underwater cameras, diving phones, and underwater measurement tools. The lower camera is connected to the monitor above the water surface through the camera cable. The staff above the water surface can see the actual underwater inspection situation through the monitor and communicate with the diver through the diving phone. This method can solve some problems under certain circumstances, but other Many personal safety factors are involved, such as water pressure safety, breathing safety, electricity safety, etc., resulting in cumbersome inspection procedures and high costs
