Repeater for detecting water storage tunnel

Abstract

The invention discloses a repeater for detecting a water storage tunnel, and the repeater is put into the water storage tunnel through an external repeater receiving and transmitting device, and provides a communication signal for a machine to detect the water storage tunnel. The repeater comprises a base, a direction controller, an upper guide plate, a communication device and a power supply device, wherein the base is of a tumbler structure which is approximately circular and is light in top and heavy in bottom, and the overall gravity center of the repeater is located below the circular center, so that the repeater can be reset to an upright state after swinging when encountering an external transverse acting force; the direction controller is installed on the base and used for finely adjusting the posture of the repeater according to the pressure difference caused by water flow on the two sides so that the signal transmission direction of the communication device can be roughly thesame as the water flow direction. According to the invention, the problems that after the repeater is put into the water flow of the water storage tunnel, the repeater inclines or falls into the water flow when encountering torrent, the repeater does not recover to the vertical state any more, and the signal transmission directions of the repeater are inconsistent can be solved.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a repeater used for robots to detect water storage tunnels. Background technique [0002] The tailing mine is a place formed by damming and intercepting the mouth of the valley or surrounding land. It is mainly used to stack and store tailings or other industrial waste discharged from metal or non-metal mines for ore screening. The tailing mine is a man-made debris flow hazard source with high potential energy, and there is a danger of dam failure. In recent years, there have been many major safety accidents and environmental accidents, which pose a great threat to people's property and life safety. Therefore, the tailing mine is carried out. Efficient safety monitoring is very important to ensure the safe operation of tailing mines and to eliminate hazards in a timely manner. [0003] Tailings ponds are generally composed of tailings stockpi...

AI Technical Summary

Problems solved by technology

[0005] 1. The internal structure of the water storage tunnel is complex, there may be torrents or strong convection, or toxic gases will be released in mineral wastewater, and the flood has certain uncertainty and delay, and manual detection is very dangerous ;

[0006] 2. Manual detection is labor-intensive and low-efficiency

When the robot detects the condition of the water storage tunnel, a communication device needs to be installed in the water storage tunnel to facilitate the robot to transmit the detected data to the external controller for analysis; currently, there are few such facilities in the water storage tunnel; Installing a fixed communication facility in a water storage tunnel that needs to be tested requires a huge amount of work and high cost, and it is also dangerous to install a communication device manually into the tunnel; there is currently a solution that uses a robot to carry a communication device into the water storage tunnel Put the communication device in a suitable place as needed, but after the communication device is dropped into the water flow, there are two situations:

[0008] 1. The communication device is easy to tilt, or when encountering a torrent, the communication device will not return to the upright state after being tilted, which will affect the communication effect;

[0009] 2. The signal transmission direction of the communication device in the water flow is not uniform, which will cause the signal strength in the water storage tunnel to be different, which will affect the transmission of robot detection data
