Water pollution monitoring device for environmental protection

Abstract

The invention belongs to the technical field of environmental monitoring, and provides a water pollution monitoring device for environmental protection. The monitoring device comprises: a monitoring chamber; a sampler, which is internally provided with at least two sampling cavities and is used for extracting water samples in a monitored area; a detection probe, which is used for monitoring and analyzing the water samples; and a self-control sampling mechanism, which is connected with the sampling cavities and is used for controlling the sampling cavities to extract the water samples at different depths. The self-control sampling mechanism comprises: electric pumps, which are connected with the sampling cavities and used for extracting the water samples and conveying the water samples into the sampling cavities; and a pressure control switch, which is connected with the electric pumps and used for controlling switches of the electric pumps to be started according to the water pressure of different depths of the monitored area and controlling the electric pumps on the different sampling cavities to be independently started and stopped under different water pressure environments so as to extract the water samples at different depths by utilizing the different sampling cavities. The self-control sampling mechanism is arranged on the sampling cavities, so sampling at different depths can be completed, and the water samples are prevented from being polluted.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a water pollution monitoring device for environmental protection. Background technique [0002] Water pollution is the reduction or loss of the use value of water caused by harmful chemical substances. The harmful substances in polluted water and sewage will poison aquatic organisms, affect drinking water sources, scenic spots, and endanger people's lives. [0003] The increasing water pollution has posed a major threat to human survival and safety. In order to protect the environment and protect life and health, it is necessary to monitor the water pollution status of public waters or pollution sources, so as to provide data support for water pollution control. [0004] The monitoring equipment obtains the monitoring results by sampling and analyzing the water body. In order to ensure the universality and accuracy of the data, not only the surface wa...
