Sampling and detection device for river pollution

Abstract

The invention discloses a sampling and detection device for river pollution. The sampling and detection device comprises a base, wherein the base is fixedly mounted on the ground on one side of a river; a sampling mechanism is arranged on the base; a neutralizing mechanism is arranged on the sampling mechanism; a detection and holding mechanism is arranged on the base; a cleaning mechanism is connected with the detection and holding mechanism; a sewage treatment mechanism is arranged on the base; an auxiliary mechanism is arranged on the base; a collection mechanism is placed on the base; a solar power generation device is arranged on the ground on one side of the base; and a controller is arranged on one side of the upper surface of the base. According to the sampling and detection device, sampling is carried out through the sampling mechanism; the depths can be changed so that river water at different depths can be obtained; the pH values of the river water can be neutralized throughthe neutralizing mechanism and the metals contained in the solution are precipitated; and the solution is filtered out through the detection and holding mechanism and then the impurities are kept. The sampling and detection device has the beneficial effects of being simple in structure and strong in practicability.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sampling and detection device for river water pollution. Background technique [0002] River water pollution is an important part of urban environmental construction, and it needs to be sampled and tested to protect the urban environment. [0003] A general sampling detection device, for example, the patent number is CN201720545063, and the patent name is a patent for a river water quality detection sample collection device, which mainly uses the ability to fix the sample collection bottle on the river water quality detection sampling device, the floating piston and the water inlet. The set steps can extract and collect water quality samples conveniently and quickly, the operation is simple, and the advantages of improving the efficiency of water sample extraction solve the problem that some existing water quality testing and sampling devices cannot conveniently collect ...

[0003] A general sampling detection device, for example, the patent number is CN201720545063, and the patent name is a patent for a river water quality detection sample collection device, which mainly uses the ability to fix the sample collection bottle on the river water quality detection sampling device, the floating piston and the water inlet. The set steps can conveniently and quickly extract and collect water quality samples, the operation is simple, and the advantages of improving the efficiency of water sample extraction solve the problem that some existing water quality testing and sampling devices cannot conveniently collect water quality samples. The operation is cumbersome and affects the The problem of water sample extraction efficiency

[0004] However, there are some problems in the use of this device. It can only select a fixed height of the water level for sampling, and the sample taken is relatively simple. Generally, when changing the sampling height, it often needs to use electric energy. Unexpected consequences. River sewage sometimes contains highly acidic and alkaline solutions. Although it is diluted with water, it still contains certain pollutants. If the solution is taken away directly, due to its large weight, the number of samples taken is small. , affecting the test results
