When the motor 91 rotates forward, the motor 91 drives the incomplete gear 92 to rotate forward, so that the incomplete gear 92 can drive the rack 2 93 to move upward, thereby ensuring that the filter screen 88 is always at the top of the filter tank 82, preventing the impurities from being too large and causing the filter screen 88 to move downward, thereby preventing the impurities from falling into the collection tank 83. When the motor 91 is reversed, the rack 2 93 can drive the filter screen 88 to move downward, so that the spring 86 is deformed. When the filter 88 is disengaged, the spring 86 drives the movable block 87 to vibrate up and down on the outer wall of the limiting rod 2 85, so that the impurities blocking the filter screen 88 can fall off, thereby ensuring the filtering effect of the filter screen 88 and extending the service life of the filter screen 88. The rotating block 56 can drive the rotating shaft 55 to rotate, thereby driving the driving gear 54 to rotate, thereby synchronously driving the rack 1 53 meshing at both ends of the driving gear 54 to slide in the fixed block 51, so that the rack 1 53 can synchronously drive the symmetrically installed installation box 42 to move in the opposite direction, so that the installation box 42 can be moved to the outside of the detection chamber 2, so that the groundwater can be detected by the detection instrument installed in the installation box 42 in advance. After the detection is completed, the rotating block 56 is reversed to move the installation box 42 into the detection chamber 2. The device has a high degree of integration, and there is no need to take samples and then send them for inspection. The detection time is short and the process is simple, and the samples can be detected in time.
