Description

Technical Field

[0001] The utility model relates to the technical field of groundwater sampling, and more particularly to a groundwater sampling device. Background Art

[0002] Shallow groundwater is formed by atmospheric precipitation and surface runoff. The water quality and quantity are affected by precipitation and runoff. The burial depth is generally between a few meters and more than ten meters. It is greatly affected by the soil environment and soil sanitation conditions. It is an important basis for studying non-point source pollution. When groundwater source collectors collect samples, they often need to use groundwater sampling devices.

[0003] After searching, a groundwater sampling device disclosed in publication number CN219625123U includes a water pump and a collecting bucket arranged at the water outlet end of the water pump. The water suction end of the water pump is connected to a water suction cylinder. A support rod is fixedly installed on the inner wall of the water suction cylinder. A cleaning assembly is provided on the bottom of the support rod through a driving member, and the outer surface of the cleaning assembly is fixedly installed on the inner wall of the water suction cylinder. The cleaning assembly is used to prevent debris from blocking the water suction part at the bottom of the water suction cylinder. A crushing assembly is provided on the top of the support rod, and the crushing assembly is used to further crush smaller debris.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, the drive motor is located inside the water absorption cylinder. When the drive motor needs to be inspected and maintained, it cannot be inspected and maintained quickly. The water absorption cylinder must be disassembled as a whole before the drive motor can be taken out. The operation is relatively troublesome. For this reason, we propose a groundwater sampling device. Utility Model Content
