Water level detection device and method for water conservancy project

Abstract

The invention provides a water level detection device and method for water conservancy. The water level detection device comprises a mounting bracket; a lifting screw rod is in threaded connection with two mounting frames, and the outer wall of the detection water column is sleeved with the mounting frames; the interior of the detection water column is slidably connected with a rhombic buoy; and a rotating pressing rod is rotationally connected to a stand column at the top of the detection water column, the left end of the rotating pressing rod is connected with the top end of a pressing-down ejector rod, and the bottom end of the pressing-down ejector rod is slidably connected to the interior of the left side of the alarm control switch box. The diamond-shaped detection water column can reduce the impact force of water in water and reduce the damage to the detection water column, and when the detection water column is inserted into the water, the water slowly overflows into the detection water column from the water inlet at the bottom of the detection water column, the situation that the water flow quickly enters the detection water column to cause inaccurate detection is avoided, and meanwhile, in the water level rising process, air in the detection water column is exhausted out of an exhaust hole, so that the pressure in the detection water column is kept constant.

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a water level detection device and method for water conservancy projects to solve the problem that the existing similar water level detection devices and methods for water conservancy projects will be affected by the cylinder or square shape when they are in use. The impact of large water flow will cause impact damage to the shell of the water level detection device, and when the water level detection device is placed in the water, the circuit structure is very vulnerable to short circuit caused by the corrosion of the river water
