Tongue-tube relay-type water level probe

Abstract

The invention provides a tongue-tube relay-type water level probe. The tongue-tube relay-type water level probe comprises a probe cap, a heavy hammer, a vent hole, a tongue-tube relay switch and a protective cover, wherein the probe cap is used for sealing the port of the heavy hammer; the heavy hammer is used for providing gravity; the vent hole is used for the emission of the compressed air in the protective cover; the tongue-tube relay switch is used for turning on / off an external alarm and is sealed in a gas tight manner; the protective cover is used for preventing the tongue tube relay switch from being damaged by external forces; the heavy hammer is positioned at the middle upper part in the protective cover; a first cavity is arranged at the lower part of the protective cover; the tongue-tube relay switch is mounted in the first cavity; a closed second cavity is arranged in the center of the heavy hammer; an external conducting wire and the connector of the tongue-tube relay switch are mounted in the second cavity; the port of the heavy hammer is sealed with the probe cap; the external conducting wire penetrates through the probe cap and the second cavity in sequence from the top down and is connected to the connector; and the vent hole is formed in the protective cover in a position at the top of the first cavity. The tongue-tube relay-type water level probe has the characteristics of compact structure, high sensitivity, low false alarm rate, long service life and the like, and can be extensively applied in the field of water level measurement.

Description

technical field [0001] The invention relates to detection technology, in particular to a dry reed switch relay type water level probe. Background technique [0002] The tailings ponds produced in industrial production and used to build dams to intercept valley mouths or enclosures have become a major source of danger for man-made debris flows due to their high potential energy. At present, there are a large number of tailing ponds in my country, and tailing pond accidents are on the rise in recent years. The change of the infiltration line of the tailings pond is the key to predict the accident of the tailings pond. Affected by many factors, the position of the infiltration line of the tailings pond cannot be obtained through theoretical calculation, and must be obtained by on-site measurement. [0003] In practical application, the change of the infiltration line of the tailings pond is caused by the change of the water level. At present, there are basically two types of...

AI Technical Summary

Problems solved by technology

Since the probe must be in contact with water, the two wires stained with water film or mist will short-circuit, thus making it impossible to judge the actual water level

The second type of water touch probe has poor sensitivity, even after leaving the water surface, the alarm will continue to alarm, making it impossible to determine the actual water level

[0004] It can be seen that the existing technology has problems such as simple structure, low sensitivity, high false alarm rate, and short service life.
