Automatic angle-variable water quality monitoring water taking tank having stretching rod

Abstract

The present invention discloses an automatic angle-variable water quality monitoring water taking tank having a stretching rod. The automatic angle-variable water quality monitoring water taking tank is characterized by comprising an operation plate and a water quality monitoring water taking tank, wherein the operation plate comprises a storage battery, a stepping motor, a wire take-up wheel and a stretching rod, the storage battery is positioned inside the operation plate, the stepping motor is connected on the storage battery in parallel and is fixedly provided with the wire take-up wheel, the wire take-up wheel is fixedly arranged on the rear end of the stretching rod, the front end of the stretching rod is provided with a pulley, the water quality monitoring water taking tank comprises a tank body, a tank mouth and a weight balancing block, the tank body comprises a cylinder with sealing heads respectively welded on the upper end and the lower end, and a tank bottom, the tank mouth is welded with the sealing head through the lower end of a piston sleeve and is communicated with the tank body, and the weight balancing block is fixed on the tank bottom through the screw. The automatic angle-variable water quality monitoring water taking tank of the present invention has the following beneficial effects that: the automatic multi-angle conversion of the sampling tank can be achieved, the sampling range is increased, the automatic sampling can be easily achieved, the sectional weight balancing along with the water depth can be easily achieved, the labor intensity is reduced, the design is rational, the sealing property is good, the quality of the sampled water sample is reliable, the applicable water depth range is wide, and the operation is easy.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an automatic variable-angle water quality monitoring water intake tank with a telescopic rod. Background technique [0002] At present, most of the water sample collectors are closed cylindrical structures, and the bottom surface and the top surface are equipped with flat one-way check flaps, or the closed cylinder cover at the bottom of the tube is equipped with plate-type check flaps and other structural forms. When it is lowered, the flaps are automatically (or rely on the force of the rope) opened upwards. After the water is filled, the water extractor is installed, and the flaps are automatically closed until they are lifted out of the water. 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 the water samples taken from different layers of ...

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

[0003] The patent number is: 201110150785.7, and the name is "Water Quality Monitoring Water Intake Tank", which solves some of the problems, but it cannot be automated in the process of water quality sampling, which is inconvenient for experimenters to take samples
