A positioning assembly is provided in the middle, and the positioning assembly includes a plurality of positioning holes 11 equidistantly penetrated and opened on the upper surface of the fixed plate 2, and a plurality of positioning columns 12 matching the positioning holes 11 are equidistantly fixedly installed on the lower surface of the base 3, an electric telescopic rod 8 is fixedly installed on the lower surface of the mounting frame 1, and a driving plate 13 is fixedly installed on the telescopic end of the electric telescopic rod 8, and driving rods 14 are fixedly installed at the four edge positions of the driving plate 13, and a driving groove 18 is penetrated at the bottom end of the rotating plate 10, and the driving rod 14 is slidably installed with the inner wall of the driving groove 18.

[0024] The upward movement of the electric telescopic rod 8 drives the driving plate 13 to move upward, so that the driving plate 13 drives the driving rod 14 to move upward, and the driving rod 14 drives the rotating plate 10 to move closer to each other around the rotating fulcrum through the driving groove 18, and the rotating plate 10 drives the pressure angle 17 to abut against the bevel angle 16, and the base 3 is firmly fixed on the upper surface of the fixed plate 2 through the abutment between the pressure angle 17 and the bevel angle 16. When fixing the base 3 through this device, there is no need to tighten and loosen multiple bolts, and the installation process is simple and easy to operate, which reduces the consumption of manpower and time.

[0025] In this embodiment, a column 4 is fixedly installed on the upper surface of the base 3, a sliding sleeve is fixedly installed on the circumferential outer surface of the column 4 near the top, a sliding rod 5 is slidably installed on the inner wall of the sliding sleeve, and a radar water level meter 6 is fixedly installed on the telescopic end of the sliding rod 5. The radar water level meter is a commonly used water level measuring device that uses radar technology to perform non-contact water level measurement. It determines the water level by emitting radar signals and receiving echoes. The outer surface of the sliding sleeve away from the end of the column 4 is threadedly connected with a clamping bolt 7, and one end of the clamping bolt 7 is against the outer surface of the sliding rod 5.

When fixing the base 3 through this device, there is no need to tighten and loosen multiple bolts. The installation process is simple and easy to operate, reducing the consumption of manpower and time. When fixing the radar water level meter 6, the installer manually pulls out the slide rod 5 to determine the required length, and then manually tightens the clamping bolt 7 to fix the position of the slide rod 5.
