The invention discloses a fixed-point multi-sampling device for environmental law
enforcement and forensics. The fixed-point multi-sampling device comprises a cabinet, a controller, a water pump, a
water quality sensor, and a camera. The controller is arranged inside the cabinet. The water pump is arranged inside the cabinet and electrically connected with the controller. The
water quality sensoris located outside the cabinet and is electrically connected with the controller. The camera is used for performing video shooting on the sampling position. The water inlet of the water pump is arranged with a water inlet
pipe which extends outside the cabinet, and the water outlet is arranged with a water outlet
pipe which extends outside the cabinet. At least one sampling
bottle is arranged on the part, located in the cabinet, of the water outlet
pipe. The controller can control the start and stop of the water pump through the
water quality condition of the
pollution source detected by the water quality sensor. Each sampling
bottle communicates with the water outlet pipe through a connecting pipe. The ends, far away from the sampling
bottle, of the connecting pipes are connected with theupper surface of the water outlet pipe. According to the fixed-point multi-sampling device for environmental law
enforcement and forensics, the whole-process
video recording can be performed on the sampling process, multi-sampling can be performed, and the influence of the previous sampling on the next sampling can be avoided as much as possible by the arrangement of the pipe.
