Water sample filtering device for environmental detection

The utility model discloses a water sample filtering device for environmental detection, which relates to the technical field of environmental detection and comprises a motor, a transmission shaft and a rotating component, the output end of the motor is provided with the transmission shaft, and the rotating component for reducing impurity precipitation is arranged at the top of the outer wall of the transmission shaft. The rotating assembly comprises a transmission rod, a connecting rod, a clamping block, a fixing block, a fixing rod and a rotating shaft, and the connecting rod is arranged on the side, away from the transmission shaft, of the transmission rod. According to the device, the rotating assembly is arranged, and the driving motor drives the transmission rod to rotate, so that the filtering barrel does reciprocating swinging motion, impurities accumulated on the inner wall cannot be accumulated at the bottom of the inner wall in the process of filtering and detecting a water sample, and the phenomen
