Problems solved by technology

However, in the prior art, most of the sampling of water quality is to collect the water quality on the surface of the water flow. However, it is not easy to accurately collect the water quality at the predetermined depth. Therefore, there is room for improvement.

Abstract

The invention discloses a river water quality sampling device. The river water quality sampling device comprises a sampling pipe, a solenoid valve, a load-bearing body, a scale rope, an electric rope winder, a peristaltic pump, a drainage pipe, a sampling bottle and a controller; the solenoid valve is arranged at one end of the sampling pipe, the other end of the sampling pipe is connected with a water inlet of the peristaltic pump, a water outlet of the peristaltic pump is connected with the sampling bottle through the drainage pipe, the load-bearing body is fixed to the water inlet end of the sampling pipe, the scale rope is connected between the electric rope winder and the load-bearing body, and the peristaltic pump, the solenoid valve and the electric rope winder are all connected with the controller. Compared with the prior art, according to the river water quality sampling device, the scale rope is loosened through the electric rope winder, the load-bearing body is dropped to water, the water entering depth is mastered through scales on the scale rope, when the load-bearing body is dropped to the predetermined depth, the solenoid valve is switched on, the peristaltic pump is started simultaneously for sampling till a needed sample is collected in the sampling bottle, and therefore the sample at the needed depth can be collected standardly.

Description

technical field [0001] The invention relates to a water quality sampling device, in particular to a river water quality sampling device. Background technique [0002] A water quality sampler is a device for collecting water quality samples. There are two kinds of water quality manual sampler and water quality automatic sampler. The material of the water quality artificial sampler must not affect the composition of the water sample, be easy to wash, and must not have any residue on the previous sample. The water quality automatic sampler is a bucket-type sampler suitable for flow proportional to it, and it is an intelligent multifunctional suction-type water sample bottle sampling device. It can realize multiple sampling methods (quantitative sampling, timing quantitative sampling, timing flow proportional sampling, constant flow quantitative sampling and remote control sampling) and multiple bottling methods (single sampling per bottle-single sampling) according to water s...
