Technical Field

[0001] The utility model relates to the technical field of water conservancy facility detection equipment, in particular to an automatic monitoring device for seepage and seepage pressure of a dam. Background Art

[0002] A dam is a water-retaining structure used to intercept water flow in rivers and channels. It can raise water levels, regulate the flow of other tributaries, and concentrate water head at a certain location in the water system. These processes help to form reservoirs, which can effectively adjust the flow route and water volume of the water system, and are beneficial for flood control, water storage for irrigation, and hydropower generation. Therefore, dams play an extremely important role and are also a key water conservancy facility in the development of human history. The construction and management of modern dams are also more rigorous and standardized. During the use of dams, various monitoring equipment will be arranged to monitor various data of the dam to ensure the safety of the dam. Among them, the detection of seepage and seepage pressure is a basic daily task.

[0003] Most of the existing dam seepage and pressure detection equipment currently use water pressure gauges for detection. After drilling a hole, it is installed at a preset position in the hole and filled with sand to detect the seepage pressure. However, most of them lack protection design for cables, and there is a lack of means to compact and fill the sand. The sand is often filled loosely, which affects the installation of the detection equipment and the detection effect.

[0004] In order to solve the above problems, we have made improvements and proposed an automatic monitoring device for dam seepage and pressure. Utility Model Content
