Retractable hatch container and floating element equipotential connection system

Abstract

The invention relates to an equipotential connection mechanism, and especially relates to a retractable hatch container and floating element equipotential connection system. The retractable hatch container and floating element equipotential connection system is characterized by comprising a pedestal, a rotation shaft, a static electricity export device, a wide copper compound strand wire, a swinging coil spring and a shell, wherein the shell is divided into an inner shell and an outer shell, the inner shell and the outer shell form a cavity A and a cavity B, the inner shell and the outer shell are coaxially distributed by taking the rotation shaft as an axis, the swinging coil spring is coiled on the rotation shaft, two ends of the swinging coil spring are respectively fixed on the rotation shaft and the inner shell, thus, the number of turns of the swinging coil spring varies along with the rotation of the rotation shaft in the cavity B; the wide copper compound strand wire is coiled in the cavity A on the periphery of the inner cavity, one end of the wide copper compound strand wire is fixed on the rotation shaft while the other end passes through the opening of the cavity A and further connects the floating element through the static electricity export device, the shell is connected with the pedestal, and the pedestal and the upper end of the retractable hatch container are fixed together through a soleplate. The invention provides a retractable hatch container and floating element equipotential connection system which is excellent in safety and high in reliability, so as to prevent lightning and static electricity, and avoid fire disaster.

Description

technical field [0001] The invention relates to an equipotential connection mechanism, especially an equipotential connection system between a retractable hatch container and a floating element, which is used for the equipotential connection between the hatch container and the floating element, and can protect against lightning and static electricity and prevent fires. effect. Background technique [0002] The hatch container in the present invention mainly refers to the steel welded open storage tank that is used for storing such as crude oil, diesel oil, gasoline, benzene and some chemical liquid media, and these liquid media are generally volatile, and the floating element is to prevent these liquid media from evaporation. [0003] Since there is a certain gap between the hatch container and the floating element, there is a sealing tape between the gap, and the friction between them and the hatch container wall will generate static electricity, which needs to be effectiv...

AI Technical Summary

Problems solved by technology

In order to achieve the balance of the electric field, the induced charge on the floating element in the hatch container will be discharged according to a certain rule, but the existing two braided flexible wires connecting the hatch container and the floating element are difficult to meet the instantaneous discharge of the induced charge. An instantaneous potential difference is formed between the mouth container and the floating element
