Problems solved by technology

[0003] Based on the discovery of the above-mentioned inventors, the existing well-flushing sampling pump for environmental monitoring wells mainly has the following deficiencies, for example: when the water in the monitoring well is drawn to the bottom, due to the bottom of the well contains a large amount of silt , so that the sediment follows the water flow, and the sediment will stay at the port of the sampling pump, causing the sediment and the impeller to rub against each other, thereby slowing down the rotation speed of the impeller and causing the pumping speed to slow down

Abstract

The invention discloses a well washing sampling pump for an environment monitoring well, the structure of the well washing sampling pump comprises a main body, a base and a top cover, the bottom of the main body is provided with the base, the top cover is clamped at the top of the main body, the main body comprises a heat dissipation shell, a rear clamping cover and a water pumping device, the water pumping device comprises a rotating impeller, a water inlet and a water pumping groove, and the rotating impeller comprises a rotating shaft, an impeller and a sealing device. The impeller comprises an impeller body, a friction block, an inlet groove and a sand discharging opening, the sand discharging opening comprises a sand discharging groove, an elastic piece block and a deformation groove, the impeller is driven by the rotating shaft to rotate anticlockwise, so that water flow and silt mixed in the water flow can directly enter the inner side of the impeller, and the impeller pushes the water flow and the silt to flow into the water pumping groove; friction between impeller rotation and silt can be reduced, the rotation speed of the impeller is increased, and the extraction speed of the silt mixed in water is increased.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a well cleaning and sampling pump for environmental monitoring wells. Background technique [0002] The well washing and sampling devices for groundwater monitoring wells are mainly completed by Baylor tubes, submersible pumps, peristaltic pumps or self-priming pumps; Water from the surrounding aquifers is pumped out of the wells for water quality, and water from the surrounding aquifers flows into the monitoring wells. Staff then sample water from these fresh aquifers for analysis. [0003] Based on the discovery of the above-mentioned inventors, the existing well-flushing sampling pump for environmental monitoring wells mainly has the following deficiencies, for example: when the water in the monitoring well is drawn to the bottom, due to the bottom of the well contains a large amount of silt , so that the sediment is drawn with the water flow, and the sediment will sta...
