Ground pile type water level monitoring device

Abstract

The invention relates to a ground pile type water level monitoring device. The water level monitoring device comprises an outer barrel body, an inner barrel body, a water level monitoring unit, and a sealing cover. The outer barrel body is fixed in an installation hole in the ground of a to-be-monitored water level when installed; the inner barrel body is detachably sleeved with the outer barrel body; the water level monitoring unit is arranged in the inner barrel body, and the water level monitoring unit comprises a water level monitoring circuit, two starting contactors electrically connected with the water level monitoring circuit and an ultrasonic probe; the sealing cover seals the water level monitoring unit in the inner barrel body. The ultrasonic probe is arranged in a probe fixing groove in the inner surface of the sealing cover, and the two starting contactors are respectively sealed and arranged in the sealing cover and exposed on the upper surface of the sealing cover. When accumulated water occurs, the two start contactors are communicated, and the water level monitoring unit is started and starts monitoring. The ground pile type water level monitoring device achieves a ground pile type fixed installation, is convenient for maintenance and secondary moving and installing, and has the functions of starting with water, intelligent monitoring frequency changing, ultra-low power standby and the like.

Description

technical field [0001] The invention relates to the field of water level monitoring, in particular to a ground pile type water level monitoring device. Background technique [0002] In recent years, my country has been affected by extreme weather, with frequent rainstorms in various places, and the problem of urban waterlogging is becoming more and more serious. In many cities, roads are flooded and garages are flooded during heavy rains. When the urban drainage system cannot quickly solve the waterlogging problem, timely monitoring and early warning of possible flooded areas is very important. For the area where the warning is issued, the traffic can be evacuated in time, and the owner can be notified in time to avoid the recurrence of the disaster. [0003] Existing water level monitoring generally uses sensors such as float type, pressure type, ultrasonic type, or radar type. The above water level sensors generally have the problems of complicated installation and mainte...

AI Technical Summary

Problems solved by technology

[0003] Existing water level monitoring generally adopts sensors such as float type, pressure type, ultrasonic type or radar type. In the actual application process, the above water level sensors generally have the problems of complicated installation and maintenance, difficult construction and high cost.

For example, the existing ultrasonic water level gauges are generally installed above the position to be measured, often requiring a special support rod, so the construction is difficult, the cost is high and the maintenance is not convenient

In addition, since the propagation speed of ultrasonic waves in the air is greatly affected by temperature, temperature compensation needs to be designed, the structure is relatively complex, and the cost is high
