Self-locking electrostatic discharge alarm instrument for human body

Abstract

The invention relates to a self-locking electrostatic discharge alarm instrument for human body. The alarm instrument comprises an electrostatic conducting ball assembly, a first pipe fitting, a shellbody, a second pipe fitting, a bending tube, a linear bearing and a self-locking assembly, and the self-locking assembly comprises a tension spring mounting bracket, a bearing mounting bracket, a V-shaped marble, a deep-groove ball bearing and a tension spring. At ordinary times, the bending tube is locked and can not be accessed by a personnel, the personnel presses the electrostatic conductingball assembly with a stroke of 27 mm, the bending tube is unlocked, and the personnel can push the bending tube to enter. After the personnel enters, the bending tube automatically rebounds back and is locked; the bending tube can only be pushed away after the electrostatic conducting ball assembly is pressed again to unlock the bending tube; and rebounding and locking of the bending tube can be achieved automatically, the alarm instrument functionally completely meets the safety requirements that the personnel can only pass through after discharging static electricity, and can be installed atentrances of explosive areas such as oil and gas, that the entering personnel can eliminate 100% of static electricity of the human body can be ensured, and the hidden danger of accidents caused by static electricity ignition is eliminated.

Description

technical field [0001] The invention relates to an electrostatic discharge alarm device, which belongs to the field of security equipment, in particular to a self-locking human body electrostatic discharge alarm device. Background technique [0002] Personnel entering the pump room, oil tank escalator, oil tank sampling port, operating platform in the loading and unloading operation area, sampling place in the device area, gas station unloading port and other dangerous work places need to discharge human body static electricity. The existing intrinsically safe human body The electrostatic discharger is in the form of a column. Although it can eliminate the static electricity of the human body, the premise is that the staff need to consciously touch the electrostatic discharge ball on the device. If you forget to touch it, then there is a possibility that the static electricity of the human body will not be released and enter the dangerous workplace, causing potential safety ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problem that employees do not release the static electricity in the human body unconsciously and enter the explosive area such as oil and gas to cause accident hazards, the invention provides a self-locking human body static electricity discharge alarm device, which can ensure that the personnel who enter can completely eliminate the static electricity of the human body and eliminate static electricity. Ignition accident hazard
