Problems solved by technology

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. At the same time, due to the buoyancy of the air in the bottle, the sinking of the sampler is resisted. In places where the water flow is fast, it will cause the entire device to float and sway, which will quickly consume the physical strength of the sampling personnel. Sampling flaws

Embodiment Construction

[0043] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined in the present application.

[0044] Such as Figure 1-6 Shown is a schematic diagram of the relevant structure of a sampling device for environmental monitoring provided by the present invention. In the present invention, with image 3 For example, one end (the right end in the figure) of the sampler where the opening is set is the rear end and the rear, and the other end is the front end and the front.

[0045] The device mainly includes a...

Abstract

The invention provides a sampling device and method for environmental monitoring. The sampling device comprises a grip, a telescopic rod connected with the grip and a sampler mounted on the telescopic rod, an opening is formed in the rear end of the sampler, a plurality of pistons are arranged in the sampler, a plurality of water inlets are sequentially formed in the sampler at intervals, and a water inlet cover is arranged at each water inlet; a piston hand wheel and a water inlet cover hand wheel are arranged below the grip, a linkage limiting mechanism is correspondingly arranged behind part of the water inlet covers, and the linkage limiting mechanism is arranged to gradually limit the pistons at intervals when the pistons move from front to back, so that a plurality of independent water storage spaces are formed in the sampler. The sampling device can be used for extracting water samples at a plurality of specified depths at one time, and can be filled with water when sinking to the water bottom, so that the problems that the sampling quality is influenced by bubbles and the like are solved.

Description

technical field [0001] The invention mainly relates to the related technical field of water quality monitoring equipment, in particular to a sampling device and method for environmental monitoring. Background technique [0002] In the process of water quality sampling, samplers at home and abroad 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 the sampler exhausting in water. At the same time, due to the buoyancy of the air in the bottle, the sinking of the sampler is resisted. In places where the water flow is fast, it will cause the entire device to float and sway, which will quickly consume the physical strength of the sampling personnel. Sampling flaws. Contents of the invention [0003] In order to solve the de...
