When in use, when the weighing fixed assembly is driven by the electric push rod 16 and the follower 18 abuts against the fixed seat 17, the weighing fixed assembly and the water storage box 5 flip.

[0025] In one of the solutions, a linear guide rail 15 is installed on the base 4 , and a slider 14 is installed on the bottom of the support plate 11 . The slider 14 slides in cooperation with the linear guide rail 15 .

[0026] Specifically, a bracket 12 is installed on the support plate 11, and one end of the electric push rod 16 connected to the support plate 11 is connected to the bracket 12.

The center of gravity of the weighing seat 8 is located at the lower side of the rotating shaft. A bearing seat 9 is mounted on the rotating shaft. The bearing seat 9 is mounted on the supporting plate 11 through a supporting seat 10, and a follower 18 is mounted on one side of the rotating shaft. Through the above structure, the weighing seat 8 can be flexibly rotated, and because the center of gravity of the weighing seat 8 is located at the lower side of the rotating shaft, the opening of the water storage box 5 is facing upward when it is in a free state.

The water storage box 5 collects the seepage of the dam body at the observation point 19, and the control unit performs timing and time period control at the same time.

[0037] The weighing sensor 7 sends an electrical signal to the control unit, which processes the electrical signal and converts it into weight data, and calculates it according to the measurement time to obtain the flow data of the dam body seepage at the observation point 19 per unit time, and sends the result to the background server.

[0038] After the measurement period ends, the control unit controls the electric push rod 16 to shorten, and the water storage box 5 moves toward the side of the fixed seat 17. When the follower 18 abuts against the cam follower 13, the cam follower 13 pushes the follower 18, and the water storage box 5 turns over to pour out the seepage water collected inside.
