Portable water quality detection device and detection method thereof

The invention relates to the technical field of detection devices, and discloses a portable water quality detection device and a detection method thereof. The device comprises a bottom plate, a sampling device is arranged on one side of the upper surface of the bottom plate, and the sampling device comprises a fixed frame, a servo motor, a moving block, a first threaded rod, a first electric telescopic rod, a supporting rod, a second electric telescopic rod, a clamping groove and a clamping block. The detection method of the device is characterized by controlling the servo motor to work; the servo motor drives the first threaded rod to rotate positively and negatively, so that the moving block arranged on the first threaded rod moves up and down; the second electric telescopic rod drives the connecting block to get close, and a handle on the sampling barrel is placed between the connecting blocks, so that the sampling barrel is fixed between the connecting blocks; the sampling barrel is conveyed to a target w
