Background
In the construction of water conservancy and hydropower engineering, water taking buildings and emptying buildings are often arranged at the dam body or the bank side in order to meet the requirements of engineering operation. In order to facilitate the operation management of water taking buildings or emptying buildings, a trash rack is usually arranged at a water inlet of the water taking building or the emptying building for blocking aquatic plants, floating trees and other dirt carried by water flow, an accident gate is arranged at the downstream of the trash rack so that a downstream pipeline or equipment of the water inlet can be closed to carry out equipment maintenance when an accident happens, and a working gate is arranged at the downstream of the accident gate in some projects for regulating the flow of an orifice. The water inlets of water taking buildings and emptying buildings generally have larger water head pressure, the operation of the trash rack and the lifting of the gate are limited by design pressure water heads, the water head difference between the two sides of the trash rack cannot be too large, and otherwise the structure of the trash rack or the gate is easily damaged. Therefore, when the trash rack runs or the gate is lifted, the pressure head difference between the front and the back of the trash rack or the gate needs to be determined, and when the head difference is too large, the gate needs to be cleaned, decompressed and filled with water and horizontally pressed, and then can be lifted.
The piezoresistive type flat pressure water level gauge can be divided into various types such as a pressure type, a ceramic type and a vibrating string type according to the internal structure of the water level gauge, the working principle of the piezoresistive type flat pressure water level gauge is that the height of a water column above a certain fixed point is measured by measuring hydrostatic pressure of the fixed point underwater based on a pressure sensing unit of a probe, and then the height of the water column is converted into the water level. The pressure resistance type flat pressure water level gauge can conveniently measure the pressure water head difference of the front and the back of the trash rack or the gate, and is widely applied to water conservancy and hydropower engineering due to low price and relatively low matching civil engineering cost. In engineering, a probe of the piezoresistive type flat pressure water level gauge needs to be fixed at a designed measuring point position, so that a water head at a corresponding position can be accurately measured, and the measuring position of the water level gauge cannot be accurately determined if the flat pressure water level gauge is delivered through a water intake building or an upstream storehouse of a water inlet of an emptying building or a gate slot well, and the measuring error is relatively large; if the level gauge is pre-buried to the measuring position through the device, the later stage can not be changed after the level gauge is damaged and loses efficacy.
