Water quality detection platform based on deepwater sampling detection method

Abstract

The invention relates to a water quality detection platform based on a deepwater sampling detection method. The water quality detection platform comprises a body, a water storage unit and an acquisition unit, wherein the water storage unit is in fixed connection with the body, a water inlet valve and a water outlet valve of the water storage unit are respectively installed on a water inlet and a water outlet, a cushion chamber is arranged at the water inlet valve, weep holes of the cushion chamber are staggerly arranged, an impeller unit of the water storage unit is arranged in the cushion chamber and comprises a variable-pitch impeller set, a positioning bearing, a rotating shaft and a support, and the blade shape of an n (n is no less than 1 and no more than N) variable-pitch impeller in the variable-pitch impeller set, from one end of the variable-pitch impeller close to the water inlet valve to the other end, satisfies the following locus equations: Xi is equal to r*cos(Thetai+2Pi*n/N), Yi is equal to r*sin(Thetai+2Pi*n/N), and Zi is equal to (n-1)*(L+a)/N+(Thetai/2Pi)<m>*[L-(N-1)a]/N.

Description

technical field [0001] The invention relates to a water quality sampling system, in particular to a water quality detection platform capable of performing deep water sampling in the fluidity of water areas. Background technique [0002] Water is the source of life. With the rapid development of society and economy, the demand and dependence on water resources in the development of human society continue to increase, which puts severe pressure on the security of water resources. Based on the urgent demand for water resources for human development, it is necessary to conduct water quality testing in water areas that need to be tested, select representative indicators, and build a water resource security evaluation index system based on the connotation of water resource security, so as to have an overall impact on the overall status of water resource security in the testing waters. Quantitative and dynamic research can reflect the basic conditions of the water resources system ...

Problems solved by technology

[0004] The underwater activity sampling platform disclosed in Chinese invention CN200810136206.1 uses a rotary push-injection collector. This sampling method is only to extract water samples. At different times in the same water area, the nature of the extracted water samples may be unstable due to the influence of undercurrents. , the test results cannot represent the real situation of water quality.
