Abstract

The invention discloses a modularization underground water monitoring, well washing and sampling device. The device comprises a micro pump module, pipeline modules, a diversion module and a plurality of micro water pump modules, wherein the plurality of pipeline modules are connected with the diversion module in a threaded way, and the diversion module is arranged at the terminal of the device; the micro pump module comprises a micro pump, a controller and a liquid sensor, and the controller and the liquid sensor are arranged in the micro pump, the liquid sensor is used for feeding a detected liquid signal into the controller and converting the liquid signal into an electric signal, and the micro pumps are started by the controller. According to the modularization underground water monitoring, well washing and sampling device provided by the invention, a reliable way can be provided for underground water monitoring, well washing and sampling with great depth, the well washing and sampling efficiencies can be effectively improved, and the labor intensity of monitors can be reduced.

Description

technical field [0001] The invention relates to a modular groundwater monitoring well washing and sampling device. Background technique [0002] For a long time, the flushing and sampling devices of groundwater monitoring wells are mainly completed by Baylor tubes, submersible pumps, peristaltic pumps or self-priming pumps. Faced with deep groundwater monitoring wells, the only option is the Baylor tube. Well washing and sampling with Baylor tube is labor-intensive, time-consuming, and extremely inefficient. Facing groundwater wells with large infiltration flow, Baylor tube can hardly complete effective well washing operations. The theoretical maximum suction distance of peristaltic pumps and self-priming pumps is only 10 meters, which makes it impossible to use such equipment for well cleaning or sampling operations when the groundwater level is deep, and cannot effectively solve the well cleaning and sampling problems of deep monitoring wells . The use of submersible pu...

Problems solved by technology

Baylor tube cleaning and sampling is labor-intensive, time-consuming, and extremely inefficient. Facing groundwater wells with large infiltration flow rates, Baylor tubes can hardly complete effective well cleaning operations.

The theoretical maximum suction distance of peristaltic pumps and self-priming pumps is only 10 meters, which makes it impossible to use such equipment for well cleaning or sampling operations when the groundwater level is deep, and cannot effectively solve the well cleaning and sampling problems of deep monitoring wells

The use of submersible pumps can be used for well cleaning and sampling of deep groundwater monitoring wells, but with the increase of head and power, its volume becomes extremely large, and it is only suitable for use in monitoring wells with larger diameters, which will greatly increase the monitoring wells. Construction cost, for monitoring wells with a depth greater than 15m, it is difficult to choose a suitable low-flow high-lift submersible pump
