Deep-well groundwater sampling device

Abstract

The invention discloses a deep-well groundwater sampling device, comprising a sampling water tank, wherein balance weights are symmetrically arranged on the circumferential outer wall of the samplingwater tank and are in sleeve connection with the sampling water tank; a water inlet cover is arranged on the bottom of the sampling water tank; a protection cover is arranged on the top of the sampling water tank; a water inlet pipe is arranged between the water inlet cover and the protection cover and located at the circumferential outer side of the sampling water tank; an air outlet is formed inthe top of the protection cover; an inflow water hopper is arranged in the top of the inner cavity of the sampling water tank; air guiding ports are formed in the left and right side walls of the inflow water hopper; and a drain pipe is arranged on the bottom of the sampling water tank. The deep-well groundwater sampling device of the invention is reasonable in structural design; on the one hand,electrically-controlled pneumatic rods and an airbag act together to make the sampling water to keep away from the side wall of a deep well, so the possibility of collision between the sampling watertank and the wall of the deep well is lowered during water sampling; and on the other hand, the airbag and the electronically-controlled pneumatic rods can be contracted when not in use, which facilitates transporting and carrying of the deep-well groundwater sampling device.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a deep well underground water sample collection device. Background technique [0002] The ecological environment refers to the whole composed of various ecological systems composed of biological communities and non-biological natural factors, mainly or completely formed by natural factors, and indirectly, potentially, and long-term impact on human survival and development. The destruction of the ecological environment will eventually lead to the deterioration of the human living environment. Therefore, to protect and improve the living environment, we must protect and improve the ecological environment. [0003] Due to the mining of mineral resources in the mining area, it has caused great damage and impact on the ecological environment of the mining area, so it is necessary to regularly detect and manage the environment in the mining area. The environment in th...

Problems solved by technology

[0003] Due to the mining of mineral resources in the mining area, it has caused great damage and impact on the ecological environment of the mining area, so it is necessary to regularly detect and manage the environment in the mining area. The environment in the mine is complex, and the manual water sampling operation is complex and easy. Accidents occur, and the complex environment makes it impossible to use drones to sample water bodies. Traditional water sample collection devices tend to collide with the well wall during the water collection process, causing the water collection tank to be dumped and damaged.
