Description

Technical Field

[0001] The utility model relates to a reservoir dam leakage flow meter, belonging to the technical field of reservoir dams. Background Art

[0002] Among the numerous small and medium-sized reservoirs in my country, most were built with earth and stone in the 1950s and 1970s. Due to the limited density of the earth-rock dam itself, the dam always has different degrees of leakage. When the water level upstream of the reservoir changes, the water flow leaking from the dam will also change. The size of the seepage becomes an important indicator to measure whether the reservoir dam is operating safely. According to the technical specifications for safety monitoring of earth-rock dams, staff must check the seepage of the dam every day, which increases the workload of staff;

[0003] For example, a reservoir dam leakage flow meter with patent publication number CN201921597775.6 includes a triangular flow measuring weir, a measuring device, a transmission unit, a client, and a power supply device for powering the entire device. The measuring device includes a cylinder with an opening downward, a controller fixed on the outer wall of the top of the cylinder, a measuring target fixed on the inner wall of the top of the cylinder, a float, a fixing plate fixed on the top of the float, and a distance sensor fixed on the end surface of the fixing plate and corresponding to the measuring target. The fixing plate is fixed to the top of the float through a support rod;

[0004] Since the length of the reservoir dam in the above-mentioned leakage flowmeter is fixed, it is not convenient to monitor the leakage flow at different water levels in different reservoir dams, and there is a certain error margin in measuring the leakage flow at the monitoring height of the adjusting structure above a single float, which has a certain adverse effect on actual use, and therefore needs to be improved. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
