Sampling device capable of determining water depth and water quality

Abstract

The invention relates to a sampling device capable of determining water depth and water quality, which belongs to the technical field of water quality monitoring and environmental protection. According to the invention, a bright-colored scale mark or bright-colored foamed material is provided between the bottom and the central part of the external side of a bucket which has an opening at its upper part and has a handle; a small concentric circular aperture is perforated at the center of circle at the bottom of the bucket, a small cylinder with a height smaller than the height of the bucket isprovided at a position where the small concentric circular aperture is located by seal welding or sticking for seal connection with the bucket, and the top of the small cylinder is sealed; a set of symmetrical small circular apertures are arranged at the bottom of the small cylinder; two freely movable flakelets are arranged at the position where the small circular apertures of the small cylinderare located; five hollow slender rods with a cavity at their center are vertically arranged to be parallel to the inner side of the bucket, and the five hollow slender rods and the small cylinder areall provided with a concave rectangular guide groove, which enables all the hollow slender rods to move along a straight line. Integral structure for the sampling device is simple; a principle used in the device is reliable; sampling steps are simple and easy; controllable water quality and water depth are achieved; and the sampling device is applicable to water quality sampling of water at a variety of water depths.

Description

Technical field: [0001] The invention belongs to the technical field of water quality monitoring and environmental protection, and relates to a sampling device capable of determining water depth and quality with a simple structure, in particular to a sampling device capable of determining water depth and water quality. Background technique: [0002] With the rapid development of social economy, the problem of environmental pollution is becoming more and more prominent, especially the problem of water environment pollution is showing the trend of regional expansion, pollution diversification and serious degree. In the face of global environmental problems and the increasingly severe water crisis, water resource protection has become an urgent problem facing human beings. In order to strengthen the monitoring of water environment quality, grasp the current situation of water quality in a timely manner, determine the temporal and spatial distribution of pollutants in water bodi...

Problems solved by technology

At present, there are some high-end automatic water quality monitoring equipment in the actual application of the existing technology, but these high-end equipment have many disadvantages such as high price, high operating cost, and difficult maintenance, which limit their popularization and application in society. , and the traditional water quality sampler also has many inconveniences and problems in the normal water quality sampling process, such as the sampling process has a strong odor, and the sampler rope will be in contact with the sampled water body; the sampling process needs to wear (disposable) rubber gloves or directly touch the skin Sewage contact, there are potential health hazards or secondary pollution problems of disposable rubber gloves; when water quality sampling at a fixed water depth is required, there is a disadvantage of large water depth control errors; In , the surface water body fills the sampler, so that the actual water sample at the specified water depth cannot be taken or less

Therefore, in summary, the existing technology generally has the disadvantages of high price, high operating cost, difficult maintenance, poor sampling accuracy, low safety performance, and large secondary pollution.
