A liquid level gauge for inspection wells

Abstract

The invention provides a liquid level gauge in an inspection well. The power source and data storage device include a first connecting rod and a sealed waterproof part. One or more batteries and a data and power manager electrically connected to the batteries are arranged in the sealed waterproof part; The monitoring device includes a top support ring and a probe protection outer ring, the two are connected by a plurality of second connecting rods, the probe protection outer ring is provided with a side wall, and the top of the side wall is connected to the probe protection outer ring on one side thereof The top of the cavity is sealed and connected, and a cavity with a top seal and an open bottom and a through part are formed between the two. The top of the cavity is provided with data and power connections, and the interior is equipped with a contact liquid level alarm probe, an ultrasonic probe and Barometric temperature probe. The advantages of the present invention are: 1) the device is divided into a power supply, a data storage device and a monitoring device, without the need for downhole operation; 2) the cavity principle can be used to protect the probe; 3) the device can be realized in both submerged and non-submerged states Level measurement.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, in particular to a liquid level gauge for inspection wells. Background technique [0002] Water level measurement in inspection wells is of great significance in the fields of municipal engineering and environmental engineering. It can effectively assist in the detection of pipeline network leakage and pipeline sedimentation monitoring. [0003] Existing water level measuring devices are mainly based on water gauges, ultrasonic liquid level gauges and pressure type liquid level gauges. However, the monitoring process of the water level gauge is too cumbersome. The ultrasonic liquid level gauge probe can only work above the waterline, and the pressure type liquid level gauge probe can only work below the waterline. The effect of floating debris. [0004] In order to solve the problems in the sewer system such as large water level changes, large solid floating objects, and probes th...

Problems solved by technology

However, the monitoring process of the water level gauge is too cumbersome. The ultrasonic liquid level gauge probe can only work above the waterline, and the pressure type liquid level gauge probe can only work below the waterline. Influence of floating debris

[0004] In order to solve the problems in the sewer system such as large water level changes, many solid floating objects, and the probe is easily damaged, and to better monitor the liquid level of the inspection well continuously and stably, a new type of inspection well liquid level gauge is urgently needed at present.
