Underground water monitoring equipment having strong anti-interference capability and used for deep well

Abstract

The invention relates to the technical field of water conservancy projects, in particular to an underground water monitoring equipment having strong anti-interference capability and used for a deep well. The equipment comprises a telemetering terminal and a water level monitor which are respectively arranged above a mounting block and below the mounting block, wherein the water level monitor is movably connected with the mounting block through an electric telescopic rod; and the mounting block is provided with a limiting assembly for buckling the wellhead of a monitored well and a clamping assembly clamped with a well wall through frictional resistance. According to the underground water monitoring equipment, the electric telescopic rod is driven to drive the water level monitor to ascend or descend, so various defects caused by descending of an existing water level monitor on the dependence the gravity of the water level monitor are overcome, and even if the water level monitor encounters the phenomena of pollutant accumulation and scaling, the water level monitor can also penetrate through the obstacles to work; in addition, as the sinking depth of the water level monitor can be controlled by remotely controlling the electric telescopic rod, operation is simple and convenient, and the sinking depth can be accurately recorded, so reliable data support is provided for subsequent research and analysis.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to groundwater monitoring equipment for deep wells with strong anti-interference ability. Background technique [0002] Groundwater is a very important resource. It is mainly used for human drinking, agricultural irrigation and industry. In order to monitor groundwater conditions in a timely and accurate manner, groundwater monitoring wells have been opened, and special monitoring equipment has been installed at the wellheads of groundwater monitoring wells. [0003] The existing groundwater monitoring equipment includes a telemetry terminal and a water level monitor. The two adopt a separate design. The telemetry terminal is fixed on the inner wall at the port of the monitoring well, and the water level monitor is put into the well water. The water level gauge cable is often wound and fixed through a load-bearing rod or a hook on the inner wall of the monitori...

Problems solved by technology

[0004] The separate design reduces the cost of the detection equipment, but also increases the difficulty of installation and maintenance. Not only does it take a long time, but also requires the staff to hang the rope down into the monitoring well and use wrenches and other tools during installation and maintenance. Operations on telemetry terminals and water level monitors can easily lead to safety accidents. In addition, since most of the domestic groundwater monitoring systems do not consider the setting of automatic well cleaning and the bio-attachment of the monitoring well tube wall, the monitoring wells are buried in the groundwater environment for a long time. Sometimes, the sinking of the water level monitor will be affected by factors such as biological adhesion, pollutant accumulation, and scaling. In addition, most of the existing water level monitors sink only by their own gravity, and the sinking depth is difficult to accurately quantify. When it is necessary to change the depth of the water level monitor, it is also necessary to manually go down to the inside of the monitoring well to work on the water level recording cable, which is relatively cumbersome, which brings certain uncertainties to the later data analysis and processing, which needs to be improved
