Embodiment 1

[0030] refer to figure 1 , a fixed-point multi-sampling device for environmental law enforcement and evidence collection, including a box body 3, a controller 10 arranged in the box body 3, a water pump 1 arranged in the box body 3 and electrically connected to the controller 10, and a water pump 1 located in the box body 3 Outside and the water quality sensor 2 that is electrically connected with controller 10 and the camera 12 that is used to carry out video shooting to sampling place, the water inlet pipe 11 that extends to the outside of casing 3 is provided at the water inlet of described water pump 1, and water outlet is provided with The water outlet pipe 8 extending outside the tank 3 is provided with at least one sampling bottle 5 on the water outlet pipe 8. When the controller 10 detects that the water quality of the pollution source is abnormal through the water quality sensor 2, it can control the water pump 1 to draw water for sampling. The camera 12 records a vid...

Embodiment 2

[0042] This embodiment is the sampling method of the sampling device of Embodiment 1, specifically comprising the following steps:

[0043] Step 1: Start the sampling device. Under normal circumstances, the monitoring device is in the activated state for a long time;

[0044] Step 2: The controller monitors the water quality of the pollution source in real time through sensors;

[0045] Step 3: When the controller detects that the water quality is abnormal, on the one hand, it will send the abnormal data to the remote attendant so that the environmental management personnel can see the abnormality in time, and on the other hand, it will take a sample.

[0046] The sampling process specifically includes the following steps:

[0047] Step 1): Start the water pump 1 and the camera 12;

[0048] Step 2): After a period of time, close the second solenoid valve 9, open the first solenoid valve 6, and delay closing the second solenoid valve to flush the water outlet pipe 8 and flush...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of environmental detection, in particular to a fixed-point multi-sampling device for environmental law enforcement and evidence collection. Background technique [0002] Water pollution sources are the sources of pollutants that cause environmental pollution in water areas. Usually refers to the places, equipment and installations that discharge pollutants to water or have harmful effects on the water environment. In the process of environmental monitoring and law enforcement of key pollution sources with large pollutant discharge, high environmental toxicity of pollutants, or large environmental safety hazards and serious environmental hazards, it is often necessary to use pollution source automatic sampling devices for pollution source law enforcement and evidence collection. Notice number: CN201721189773.4, a sewage sampler for environmental monitoring uses a pull rod and universal wheels, which makes th...
