Water quality analyzing system based on dynamic comprehensive evaluating method for water resource security

Abstract

The invention relates to a water quality analyzing system based on a dynamic comprehensive evaluating method for water resource security. The system comprises a body, a water quality detecting unit, a water level controlling unit, a water sample invoking unit, a communication unit and an external controller, wherein the water level controlling unit is fixedly connected with the body; the water inlet valve and water outlet valve of the water level controlling unit are respectively arranged on a water inlet and a water outlet; a cushion chamber is arranged at the water inlet valve; the water leakage holes of the cushion chamber are arranged in a staggered manner; an impeller unit of the water level controlling unit is arranged in the cushion chamber and comprises a variable-pitch spiral impeller assembly, a location bearing, a rotating shaft and a support; and the locus equation of the blade shape of the nth (n is greater than or equal to 1 and less than or equal to N) variable-pitch spiral impeller of the variable-pitch spiral impeller assembly from one end, closing to the water inlet valve, of the variable-pitch spiral impeller to the other end of the variable-pitch spiral impeller is as follows: Xi=r*cos(theta i+2pi*n/N), Yi=r*sin(theta i+2pi*n/N), Zi=(n-1)*(L+alpha)/N+(theta i/2pi)m*[L-(N-1)alpha]/N.

Description

technical field [0001] The invention relates to a water quality detection system, in particular to a water quality detection ship capable of performing deep water sampling and on-site analysis and detection functions 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...

AI Technical Summary

Problems solved by technology

[0003] Existing water quality testing ships with deep water sampling function use more complex equipment for deep water sampling, which will occupy a large area when used in industrial parks, are not flexible enough and not beautiful; the sampling depth is also relatively small

Moreover, there is currently no remotely operated inspection ship that can submerge the entire hull below the water surface.

[0004] The water quality monitoring ship disclosed in Chinese invention CN200920261183.7 uses a long mechanical arm for deep water sampling, and the long mechanical arm can only be extended to 200m; the mechanical arm uses rigid materials and is exposed outside the hull, which increases the occupied area of ​​the water quality monitoring ship. It is easy to interfere with surrounding objects, the depth of sampling is small, and the flexibility of the ship is poor

[0005] A submarine-type underwater detector disclosed in Chinese invention CN200420030218.3 has a front and rear cabin design, and can also generate an inclination angle for detection. The equipment is relatively complicated, the cost is high, and it does not have sampling and detection functions
