Portable water transparency measuring device suitable for river with multiple suspended matters

Abstract

The invention discloses a portable water transparency measuring device suitable for a river with multiple suspended matters, relates to the technical field of water transparency measurement, and aims to solve the problems that when more suspended matters such as aquatic plants and duckweed irrelevant to water transparency exist in a water body, the sight of measuring personnel can be influenced by measuring the water transparency by using a saikowski disc method, and then the measurement precision is greatly influenced. The device comprises a cylinder, a handheld rope is arranged above the cylinder, a floating rod is vertically placed in the cylinder, a floating rod positioner with a hole in the middle is fixedly arranged at the upper end of the cylinder, the floating rod penetrates through the hole of the floating rod positioner to be limited, and the floating rod is provided with scale marks from top to bottom; at least one opening is formed in the side wall of the lower end of the barrel, and a grating is fixedly arranged at the opening; and the lower end face of the cylinder is a transparency test disc, and the lower end of the cylinder is fixedly connected with a counterweight plumb bob. The device can reduce the influence of suspended matters irrelevant to water transparency such as aquatic plants and duckweed in water on transparency observation, and is wider in applicable water range.

Description

technical field [0001] The invention relates to the technical field of water transparency measurement, in particular to a portable water transparency measurement device suitable for rivers with many suspended solids. Background technique [0002] When the water body has a large amount of sand, suspended matter, organic matter and microorganisms, turbidity will occur and the transparency of the water will decrease. The transparency of water generally refers to the depth reached when the Sebster disc, which is black and white, becomes invisible when it is put into the water. As an important parameter to describe the optical properties of water and the degree of visibility of water, transparency is an important parameter to measure the quality of water and evaluate the eutrophication of lakes. an important indicator of transformation. Nowadays, the country is vigorously promoting the comprehensive improvement of the water environment of small and medium-sized rivers. Before th...

Problems solved by technology

[0003] The purpose of the present invention is to provide a portable water transparency measuring device suitable for rivers with many suspended substances, so as to solve the problem of measuring water transparency with the Sephardt disk method when there are many suspended substances such as aquatic plants and duckweed in the water body that are not related to the transparency of the water body. The problem that affects the line of sight of the surveyor, so that the measurement accuracy is greatly affected
