[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The utility model provides Figures 1 to 8 A reservoir water level measuring device shown includes:

[0030] A measuring tube 1, wherein two communication ports 2 are provided at the outer end of the measuring tube 1 and communicate with the inside thereof, a floating block 3 is provided inside the measuring tube 1, a reflecting plate 4 is fixedly provided at the top of the floating block 3, two slide grooves 12 are provided on the inner wall of the measuring tube 1, two sliders 13 are fixedly provided at the outer end of the floating block 3, and the two sliders 13 are respectively provided inside the two slide grooves 12;

[0034] A fixing plate 16 is fixedly provided on the outer side of the bottom end of the measuring tube 1 , and four fixing rods 17 are fixedly provided on the bottom edge of the fixing plate 16 .

[0035] The measuring tube 1 is vertically inserted into the water so that the four fixing rods 17 are inserted into the bottom of the reservoir. The total height of the measuring tube 1 is known. At this time, the water inside the reservoir enters the measuring tube 1 through the connecting port 2. The filter screen plate 9 will filter the debris in the water. The water entering the measuring tube 1 will drive the floating block 3 to float up. The floating block 3 and the reflecting plate 4 will float on the water surface. The rangefinder 7 is a prior art. The rangefinder 7 measures the distance between it and the reflector by the time used to emit and receive the laser. The rangefinder 7 will measure the distance between it and the reflecting plate 4.

The measurement result can be automatically transmitted to the terminal of the monitoring personnel, making the measurement process of the reservoir water level relatively simple and convenient. At the same time, it also avoids the situation that the water conservancy department is affected by the timely response measures caused by the untimely monitoring. The use effect is good. This implementation method specifically solves the problem that the reservoir water level measuring device existing in the prior art mostly relies on the floating indicator block and the scale plate to measure the reservoir water level in actual use. In this measurement method, the staff needs to observe to obtain the measurement result, and the water level measurement data cannot be obtained in real time, which will affect the water conservancy department to make timely response measures.
