Sample extraction device for water quality detection

Abstract

The invention discloses a sample extraction device for water quality detection, comprising a sample storage unit and a sampling unit; the sample storage unit comprises a test tube rack and a pluralityof sampling tubes, all the sampling tubes are arranged on the test tube rack, the sampling unit includes a support frame, a wire rope and a base, a reeling wheel is arranged on the support frame, thecenter of the reeling wheel is provided with a round hole, a rotary shaft is arranged in the round hole and may rotate in the round hole, one end of the rotary shaft is extended out of the round holeand connected with an operating rod, the wire rope is wound on the outer surface of the reeling wheel, the bottom end of the wire rope is connected with the base, a water pump and a motor are arranged on the base, the water pump is connected with the motor, the motor is connected with an external power source through a waterproof wire sleeved with a PVC (polyvinyl chloride) layer, the water pumpis connected with an incoming water pipe, and the incoming water pipe is connected with a sampling tube. The sample extraction device for water quality detection is simple in structure and simple to operate and can function to extract a water quality sample during water quality monitoring.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a sample extraction device for water quality detection. Background technique [0002] With the progress and development of society, environmental protection has been paid more and more attention by the country. At present, my country has listed environmental protection as a basic national policy, and paid close attention to environmental quality. As a subdivision of environmental protection, the water quality testing industry has also received It has attracted the attention of government departments at all levels. Water is the source of life. Human beings cannot do without water in life and production activities. The quality of water has become the focus of attention. In water quality testing, it is necessary to collect water quality at different locations. After analysis, the water quality in this area can be obtained. The existing method is to use fixed-point extr...

Problems solved by technology

[0004] However, in the above-mentioned technical solutions, there are still certain defects in the collection of samples. Therefore, based on the above-mentioned technical solutions, the defects of the current sample extraction device mainly lie in:

[0005] (1) The functions of existing water quality extraction devices are relatively simple, and one type of water quality extraction device can only detect water quality at a fixed depth;

[0006] (2) When it is necessary to detect water quality at different depths, it is necessary to increase the structure of the water quality detection system, which brings a lot of trouble to the workers and greatly reduces the efficiency of water quality detection
