North of china in winter of having determined, which freezes, to be provided simultaneously with water-level gauge service life to level measuring and silt to water-level gauge siltation problem
Advantage long, easy to maintain.
Technical scheme is as follows：A kind of level measurement device, including water inlet protection pipe, diversion pipe and pressure sensing
Device, the diameter of the diversion pipe are more than the diameter of water inlet protection pipe, are equipped on the tube body of the water inlet protection pipe and diversion pipe
The upper end of several inlet openings, protection pipe of intaking is equipped with fixing card, and lower end is fixedly connected with the upper end of diversion pipe, and the two connection is set
It sets, inlet opening both sides are symmetrically arranged with arc guide vanes on the outer wall of the diversion pipe, and the nozzle of lower end is fixed with sealing
Plate, the sealing plate are equipped with several silt taps, and the bottom end of diversion pipe is fixed with fixed frame, the pressure sensor setting
In the bottom inside of diversion pipe.
Preferably, the fixing card is T shape fixing cards, sets that there are two spacing holes on the montant of the T shapes fixing card, described
Protection pipe is fixed on by fixinig plate between two spacing holes.
Preferably, the distance between inlet opening is 15-20 centimetres on the tube body of the water inlet protection pipe and diversion pipe, into
Water is uniform.
Preferably, the radian of the arc guide vanes concaves towards inlet opening side, is protected to the greatest extent silt.
Preferably, the bottom of the fixed frame is equipped with fixing glue, and fixing glue lower end is arranged for tip, convenient for being fixed on pond
Bottom.
Preferably, the height of the fixed frame is 30 centimetres, slows down sediment accumulation rate of the silt to pressure sensor.
Preferably, the water inlet protection pipe and diversion pipe are that stainless steel material is made, and corrosion-resistant, service life is long.
The level measurement device of the utility model, winter pool inner water face freeze, and the water in subglacial face can pass through measuring device
On inlet opening enter in measuring device pipe, measuring device and pool inner water form linker, pass through pressure sensing in measuring device
Device measures pool inner water position high stress, according toCalculate pool inner water position height.
When being flowed into Forebay of Pumping Station due to outside water, the flow velocity of water is larger, water slug to measuring device, and silt passes through in water
Arc guide vanes form the silt guard plot of certain area in diversion pipe back side, and the sedimentation speed in the region is slower,
The three 30 centimetres high floor fixing bracket of water conservancy diversion bottom of the tube slows down sediment accumulation rate of the silt to pressure sensor, measuring device simultaneously
Silt can be emptied by the silt tap on end seal plate under diversion pipe in pipe.
When personnel have found that pressure sensor measures failure, pressure sensor can be taken out by protection pipe of intaking and be carried out
It checks or replaces, after checking or replacing pressure sensor, sensor is put into measuring device diversion pipe bottom along water inlet protection pipe
Portion is not influenced water level and is accurately measured due to water conservancy diversion tube bottom plate fixing bracket constant height.
The level measurement device of the utility model, the level measuring and sediment siltation for solving north of china in winter icing influence water
The problem of position measures, at the same it is easy to maintain to pressure sensor, and measuring environment is stablized compared with surrounding enviroment in measuring device pipe, therefore
Extend the service life of pressure sensor.
