Fixed-point sampling device for detecting water quality in urban river channel

Abstract

The invention discloses a fixed-point sampling device for detecting water quality in an urban river channel, which comprises the urban river channel, a bridge is arranged on the urban river channel, afixed-point moving mechanism is arranged on the bridge, and a sampling mechanism is arranged below the fixed-point moving mechanism; the fixed-point moving mechanism comprises a slideway, a sliding groove, stop blocks, a sliding table, a transverse sliding block, longitudinal sliding blocks, intercepting plates, spherical grooves, spherical balls and a traction line. The sampling mechanism comprises a sampling box, a transverse partition plate, a second rotating motor, a lifting line, a line outlet hole, a submerged block, a connecting ring, a limiting ring, a fixing table, a through hole, afixing bearing, a supporting table, a third rotating motor, a coupler, a rotating shaft, a winding drum, a spiral coil, a pipe inlet hole, a sliding wheel, a water storage tank and a water outlet mechanism. A controller is arranged on the lower surface of the bridge and externally connected with a remote controller. The device has the beneficial effects of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of river water quality detection, in particular to a fixed-point sampling device for water quality detection in urban rivers. Background technique [0002] There are often a lot of garbage and bacteria and microorganisms invisible to the naked eye in the rivers in the city. The garbage can be disposed of by manual salvage, but microorganisms are not easy to deal with. It is necessary to test the water quality to judge the microorganisms or other pollution contained in the water. Use corresponding methods to control it. Generally, when sampling river water, some water is simply selected from the river for testing. By artificially drawing water on both sides of the river, the side walls of the river are steep, posing safety hazards. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and design a fixed-point sampling device for water quality detection in urb...
