Water body sampling detection device for environmental protection

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a water body sampling detection device for environmental protection. The device comprises a submerged box body, water permeable holes are hollowed in the surface of the submerged box body, a recovery hole is formed in the upper end of the submerged box body, a fixed part is arranged in the recovery hole, and the fixed part is fixedly connected with the bottom of the submerged box body; a water collecting mechanism used for being matched with the fixed part is arranged in the recycling hole, a winding mechanism is further fixedly connected into the submerged tank body, one end of the winding mechanism penetrates through the fixed part to be fixedly connected with the water collecting mechanism, and an adjusting and releasing mechanism is further fixedly connected to the upper end of the submerged tank body. The device has the advantages that the device can be put into water firstly, water collecting equipment is released to the corresponding depth, then water taking operation is carried out, the water is directly conveyed to the water surface for sample recovery, the defect that samples of different levels are mixed easily when water is taken from top to bottom is effectively overcome, and the device is simple in structure and convenient to use; meanwhile, the operable depth is larger than that of traditional equipment, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a water body sampling and detection device for environmental protection. Background technique [0002] Water pollution sampling, also known as water pollution sampling, refers to the process of taking water samples from polluted water quality according to prescribed methods and a certain proportion. The type and content of substances and other related water quality parameters are used to guide production activities and take relevant measures to reduce water pollution. [0003] A Chinese patent for a sampling detection device for water bodies for environmental protection, patent No. CN109000989B, specifically discloses the following content, including a depth detection device and a sampling detection device, which can not only sample and store water bodies, but also measure water depth, and also have the ability to detect different depths of water bodi...

AI Technical Summary

Problems solved by technology

[0007] 1. The way of water intake is through the top-down method. This method is not convenient to achieve the effect of layered sampling, and it is easy to mix the water sample sampled from the lower layer with the water sample from the upper layer.

[0008] 2. When the water sample is obtained, it is greatly affected by the upper operation, and it is impossible to sample the deep water bottom sample, and the scope of use of the equipment is limited
