Detection device applied to environment water quality detection

Abstract

The invention relates to the technical field of water quality detection and discloses a detection device applied to environment water quality detection. The detection device comprises a floating plate, wherein a sampling box is arranged below the floating plate, a guiding rod is fixedly connected to the left side of the top of the sampling box, the guiding rod penetrates through the floating plateand is in sliding connection with the floating plate, a screw rod is fixedly connected to the right side of the top of the sampling box, the screw rod penetrates through the floating plate and is inthreaded connection with the floating plate, and a rotary handle is fixedly connected to the top end of the screw rod; a round opening is arranged at the central position of the top of the sampling box, and a cylinder matched with the round opening is fixedly connected to the round opening position, an inner wall of the cylinder is covered by a rubber layer, a water quality detection pen is inserted into the rubber layer, water feeding pipes are connected to the tops of a left lateral wall and a right lateral wall of the sampling box, electromagnetic valves are arranged on the water feeding pipes, a water draining pipe is connected to the central position of the bottom of the sampling box, and an one-way valve is arranged on the water draining pipe. The detection device disclosed by the invention can control the sampling box to go up and down to sample and detect water bodies at the different depths; when the electromagnetic valves are switched on, water can enter the sampling box through the water feeding pipes; namely, water quality can be detected; thus, the detection device has convenience in detection.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a detection device for environmental water quality detection. Background technique [0002] In the process of industrial production activities, a large amount of water needs to be used. After use, the water becomes industrial wastewater. Industrial wastewater refers to the wastewater, sewage and waste liquid generated in the process of industrial production, which contains Industrial production materials, intermediate products and products, and pollutants generated during the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. [0003] In order to prevent the water from being polluted, the environmental protection department will sample and test the water in the rivers and lak...

Problems solved by technology

[0003] In order to prevent the water from being polluted, the environmental protection department will sample and test the water in the rivers and lakes around the factory, and compare the obtained data with the relevant standards to ensure that the pollution of the water by industrial sewage is less; the existing water quality testing Generally, water needs to be taken first, and then sent to the laboratory for testing. When sampling water bodies, only the surface water can often be taken, resulting in inaccurate testing. For deeper water bodies, sampling is more troublesome.
