Abstract

The invention relates to the technical field of water conservancy facilities, in particular to a reservoir leakage detection device and a detection method thereof. According to the reservoir leakage detection device provided by the invention, the warp detection lines and the weft detection lines are respectively arranged in the warp direction and the weft direction of the fixed frame, the warp detection lines are connected with the warp strain gauges, and the weft detection lines are connected with the weft strain gauges, so that when a dam body leaks or piping occurs, leaked water flow moves outwards; when the reservoir leakage detection device is connected with a circuit, the leakage part extrudes the geomembrane, then local deformation of the geomembrane is caused, the local deformation extrudes the warp detection lines and the weft detection lines, then the warp detection lines and the weft detection lines act on the corresponding warp strain gauges and the weft strain gauges, and then after the reservoir leakage detection device is connected with the circuit, leakage points can be accurately positioned; the detection structure is simple, the cost is low, the method can be well applied to scenes with low water flow speed or dispersed leakage points and small seepage of a single leakage point, and the detection precision and the detection efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, in particular to a reservoir leakage detection device and a detection method thereof. Background technique [0002] Reservoirs, as water conservancy facilities for retaining flood water and regulating water flow, can play roles in flood control, water storage for irrigation, water supply, power generation, and fish farming. Among them, leakage is a common problem in dangerous reservoirs. Serious leakage problems are directly related to the safety of dams. For these dangerous reservoirs, how to find out the leakage location, leakage point, seepage direction and seepage more accurately and intuitively Leakage is very important. [0003] In the prior art, the leakage detection methods of reservoirs and hydropower stations mainly include tracer method, drilling water injection test method, flow velocity test method, sonar method and other geophysical methods. In the scene where...
