[0002] Pumping test is commonly used in hydrogeological exploration. Testers will judge the quality and composition of groundwater by pumping up water. The existing pumping test device has a relatively simple structure and function, and usually uses a water pump for suction.

[0003] For example, the prior art publication number is CN220625872U, which is a hydrogeological pumping test device. The utility model uses the impact force of the water flow to drive the power impeller to rotate through the setting of a linkage mechanism, and drives the clearing mechanism to rotate through the installation shaft, bevel gear ring, bevel gear and transmission shaft, and eliminates the setting of the motor. It can not only reduce the overall weight of the equipment, but also reduce the manufacturing cost of the equipment and enhance the market competitiveness of the equipment.
