Shallow water quality sampler

Abstract

The invention relates to a shallow water quality sampler and aims at solving the problem of insufficient representativeness of a water sample caused by the damage of a sampling bottle of the existing water sampler to a water flow field. The shallow water quality sampler comprises a handheld rod, wherein a sampling bottle is arranged at the bottom end of the handheld rod in a clamping manner. The shallow water quality sampler is characterized in that a sampling bottle body is perpendicular to the handheld rod and arranged horizontally, and two sides of the sampling bottle are respectively provided with a water inlet valve which can be opened and closed. According to the shallow water quality sampler, a universal connection structure is adopted for fixing the sampling bottle, so that the direction of the sampling bottle can be automatically adjusted along with the water flow. The sampling bottle is arranged horizontally at the bottom of the handheld rod, and the water inlet direction is conformed to the direction of the water flow and the stability of the water flow field is maintained, so that the representativeness of the water sample is high; and a universal adjustable fixing mode is adopted for fixing the sampling bottle, so that the direction of the sampling bottle can be adjusted along with the water flow when water at a part in which the water flow is difficult to judge is sampled, and the stability of the water flow field is maintained; and two ends of the top of the horizontal sampling bottle are respectively provided with an exhaust valve which is capable of smoothly and safely exhausting gas during water sampling, so that the water is prevented from being affected by the gas in the sampling bottle.

Description

technical field [0001] The invention relates to the field of water quality monitoring technical tools, in particular to a shallow water quality sampler. technical background [0002] For shallow waters with a depth of less than 5m, domestic and foreign samplers are mainly divided into 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 exhausting the sampler in water, such as the CN2833554Y patent issued by the Chinese Patent Office on November 1, 2006. Water quality sampler, CN201935826U patent announced on August 17, 2011: a water quality sampler, the water quality sampler recorded in the above two patent documents all adopts a single-mouth bottle fixed on the handle to take water, and the single-mouth bottle is difficult in the process of takin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a shallow water quality sampler that can follow the direction of water flow in order to solve the problem that the sampling bottle of the current water quality sampler destroys the water flow field and causes the water sample to be insufficiently representative.
