A water quality sampler for environmental monitoring

Abstract

The invention relates to the field of water quality monitoring equipment, and in particular relates to a water quality sampler for environmental monitoring, the water quality sampler includes a gripping rod, a bottle holder and a sampling bottle, the gripping rod and the bottle holder are connected, the bottle holder is used to hold the sampling bottle, the bottle body of the sampling bottle is vertical to the gripping rod, and is horizontally placed, the gripping rod is provided with a pulling wire rotating wheel, the pulling wire rotating wheel is winded with a pulling wire, the free end of the pulling wire is connected with one end of the sampling bottle, the pulling wire is used to incline the sampling bottle, the bottle holder can rotate relative to the gripping rod in the horizontal plane, the sampling bottle can rotate relative to the bottle holder in the vertical plane, the sampling bottle is a cylindrical structure, a vertically-placed sealing module is arranged at the left side of the sampling bottle, a horizontally-placed sealing module is arranged at the right side of the sampling bottle, and the sealing modules are used to adjust the position of the bottle body of the sampling bottle in water and seal openings at two ends of the sampling bottle. The water quality sampler can solve problems that bubbles in the sampling bottle are difficult to discharge when in sampling, a water sample is not representative for the reason that the sampling bottle destroys the flow field of a water flow, and the same kind of sampler in the prior art cannot sample in a narrow space.

Description

technical field [0001] The invention relates to the field of water quality monitoring tools, in particular to a water quality sampler for environmental monitoring. Background technique [0002] For shallow waters within a depth of 5 meters, domestic and foreign samplers are mainly divided into fully automatic unmanned sampling equipment and manual sampling equipment. Fully automatic unmanned sampling equipment is expensive in construction and maintenance costs, while manual sampling equipment mostly uses single-mouth glass bottles, which cannot solve the technical difficulty of the sampler exhausting in water. A Chinese patent with the announcement number 201935826 discloses a water quality sampler for environmental monitoring, and a Chinese patent with the announcement number 2833554 discloses a water quality sampler for environmental monitoring. The water quality sampler described in the above two patent documents The single-mouth bottle is fixed on the handle for water i...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: a water quality sampler for environmental monitoring provided by the present invention is mainly used for sampling the water quality of shallow waters, and can solve the problem that the air bubbles in the sampling bottle are difficult to discharge during sampling, and the sampling bottle destroys the water flow field. The water sample is not representative and the existing similar samplers cannot sample in a narrow space, and when the personnel cannot initially adjust the direction of the sampling bottle body, the invention can automatically and quickly adjust the sampling bottle body to make the sampling The bottle body is consistent with the direction of water flow
