A sampler for underwater water quality testing

Abstract

The invention belongs to the technical field of sampling equipment for water quality measurement, and discloses a sampler for underwater water quality detection. It includes a water collection outer cylinder, the snorkeling disk is socketed and installed at the outer bottom of the water collection outer cylinder, the sealing partition is embedded and installed in the middle of the inner wall of the snorkeling disk, and the gas storage ring disk is embedded and installed On the bottom side of the snorkeling disc, the miniature air compressor is embedded and installed on the outer side of the gas storage ring disc. In the present invention, the electromagnetic valve inside the external connection pipe is controlled by a PLC controller to open, and the external water flow can enter the top of the snorkeling disk through the external connection pipe. At the same time, through the miniature air compressor, the gas stored in the gas storage ring disk is compressed and continuously discharged into the water storage space at the top of the sealed partition, and the water flow can be discharged to the external environment again. By adjusting the weight of the snorkeling disk Reduced, so that the floating function of the water harvesting outer cylinder in the water is completed.

Description

technical field [0001] The invention relates to the technical field of oilfield water quality detection and sampling, in particular to a sampler for underwater water quality detection. Background technique [0002] Water pollution is caused by harmful chemical substances that reduce or lose the use value of water. When organic matter in sewage is decomposed by microorganisms, it consumes oxygen in water and affects the life of aquatic organisms. Water pollution has become a problem that people pay attention to and needs to be solved urgently. Before the pollution treatment, it is necessary to use the water collection device to sample the water quality. [0003] Because the sewage in the oil field has been buried underground for a long time, people need to test whether it contains toxic substances when they touch it. Usually, the test needs to manually collect the water source at the place to be tested, and then bring the water source back to the laboratory. [0004] However...
