Abstract

The invention discloses a site-clearing float device used for liquid surface volatile gas detectors. The site-clearing float device comprises a floating plate, two site-clearing structures arranged to be bilaterally symmetrical, and a site-clearing motor device; a through cavity running through the floating plate is arranged in the floating plate; the lower surface of the floating plate is provided with a right damping slot and a left damping slot; the site-clearing motor device comprises a site-clearing motor, two transmission gears, and a transmission chain, wherein the transmission chain is wound around the transmission gears in a figure-eight-shaped manner; the site-clearing motor is connected with one of the transmission gears via transmission connecting; each transmission gear is provided with a winding groove; each winding groove and a gear shaft of the corresponding transmission gear are arranged to be coaxial; each site-clearing structure comprises a drawing rope, a connecting rod, and a site-clearing plate; each connecting rod is connected with the corresponding site-clearing plate; the site-clearing plates are used for covering the lower part of the through cavity; and each connecting rod is arranged in the corresponding damping slot, and is fixedly connected with the floating plate via frictional immobilization. The site-clearing float device can be used for clearing water surface to be detected.

Description

technical field [0001] The invention belongs to the technical field of gas sampling devices, and in particular relates to a field clearing and floating device for a liquid surface volatile gas detector. Background technique [0002] At present, the in-situ sampling method for volatile gases in sewage is mainly the closed air chamber method. That is, a closed container with a certain unit area is covered on the surface of the sewage to be tested to keep the water surface sealed, and the volatilization of the gas to be detected on the surface of the sewage in the closed container is measured within a unit of time. When there are miscellaneous aquatic plants on the water surface, it is difficult for the airtight air chamber structure to completely cover the water surface, resulting in sampling failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a field clearing and floating device for a liquid level volatile g...
