Wireless water pressure transmission device

Abstract

The invention discloses a wireless water pressure transmission device, and belongs to the technical field of water pressure measurement. The wireless water pressure transmission device comprises a positioning seat, the top of the positioning seat is provided with a wireless pressure detection assembly, and the position, corresponding to the wireless pressure detection assembly, of the top of the positioning seat is fixedly connected with an outer protection assembly. According to the invention, under the mutual cooperation of the designed wireless pressure detection assembly, an outer protection assembly, a drainage mechanism, a pressurization mechanism, a pressure conversion assembly and other structures, a stainless steel shell, a pressure sensing stainless steel film and a water pressure sensor are prevented from being retested, and hardening formed on the surface of the pressure sensing stainless steel film due to long-term monitoring and affecting the precision and the sensitivity of water level measurement is avoided, so that the water pressure sensor can effectively and stably work for a long time, the higher the water flow velocity is, the more the air amount is introduced in unit time, short-time aeration cleaning can be carried out, aeration is stopped after part of strains are removed, and the membrane contact oxidation treatment process continues to be carried out.

Description

technical field [0001] The invention belongs to the technical field of water pressure measurement, and in particular relates to a wireless water pressure transmission device. Background technique [0002] In hydrological observation, geophysics and geodesy, it is often necessary to continuously measure the groundwater level, such as the "water level detection and control device and method" published by China Patent Network (public number: CN104481792B). The technical problem solved by this patent is The existing water level and liquid level detection and control methods are mainly divided into the following types: the first is the float magnetic flap type, the second is the liquid level float switch type; the third is the ultrasonic detection method, the float magnetic Flap type: This measurement method is mostly used in liquid level. It is greatly affected by water quality and minerals, and the action of the float ball is likely to cause the accumulation of metal debris in...

Problems solved by technology

[0003] The purpose of the present invention is: in order to solve the poor water quality of some water streams, the impurities in the river water are more likely to form scale, and even have strong corrosiveness. Long-term observation is easy to form hardening on the surface of the detection device, and the formation of scale will seriously affect The accuracy and sensitivity of water level measurement make the water level sensor unable to work, and a wireless water pressure transmission device is proposed
