Water quality monitoring water collecting tank

Abstract

The invention relates to a water quality monitoring water collecting tank comprising a tank body, a tank port, a clump weight, a measuring rope, and an opening rope. The tank port comprises a piston, a piston sleeve, a port cap, a spring, a square-head bolt, and a stop collar. A water inlet port is arranged on the lower part of the piston sleeve. The port cap is threadedly connected on the upper end of the piston sleeve. The square-head bolt penetrate through the port cap. The lower end of the square-head bolt is threadedly connected with the piston. The spring and the stop collar are sleeved outside the square-head bolt, such that the tank port is formed. The tank port is welded with a sealing head of the tank through the lower end of the piston sleeve. The clump weight is fixed on the cylinder bottom by using a bolt. The measuring rope is provided with dimension markers. One end of the measuring rope is fixed on the piston sleeve of the tank port through a hoop. One end of the opening rope is connected on the top of the square-head bolt through a suspended ring. When sampling is carried out in water, the opening rope is pulled up, such that the piston slides upwards along the piston sleeve under driving. The water inlet is completely opened, and water is poured into the tank body. The tank is then lifted from the water surface by using the measuring rope. The water collecting tank provided by the invention is advantaged in reasonable design, good sealing performance, reliable quality of collected water sample, wide applicable water depth scope, and effort-saving and convenient operation.

Description

technical field [0001] The invention relates to a water sample collection device in the technology of optimal deployment of water quality and quantity in river basins, in particular to a water intake tank for water quality monitoring. Background technique [0002] Basin water quality and quantity optimization allocation technology is based on the characteristics of water pollution in the Liaohe River Basin, systematically diagnoses the temporal and spatial changes of water resources in the Liaohe River Basin and the impact of water engineering regulation on the water environment changes in the Liaohe River Basin, proposes the ecological water demand plan and water resource allocation plan of the Liaohe River Basin, and studies key rivers. The water quality and quantity combined dispatching technology for water quality improvement in the section and the emergency dispatching technology for water pollution emergencies form a technical system for optimal deployment of water qual...

AI Technical Summary

Problems solved by technology

Due to the unsatisfactory design of the water inlet structure and poor sealing performance of these water fetchers, it is difficult for these water fetchers to avoid the mixing of water samples taken from different layers of water bodies, resulting in the water samples not reaching the monitoring accuracy and increasing the monitoring work. difficulty

In addition, the structure and material of the cylinder are not suitable for deep water sampling
