Intelligent patrol film sealing gas tank and intelligent patrol system of film sealing gas tank

Abstract

The invention discloses an intelligent patrol film sealing gas tank and a patrol system. Through arranging a levelling device monitoring component and/or a sealing condition monitoring component and one or multiple on-site data collection devices, the patrol period of a designer according to the conventional requirement is prolonged to once every two to six months from once every weak. When the intelligent patrol system/intelligent patrol gas tank is provided with a movable levelling device monitoring component, the sealing condition monitoring component, a piston eccentric distance monitoringcomponent, a tank position monitoring component, a piston gradient detecting component, a gas tank pressure monitoring device, a gas tank temperature monitoring device, a gas tank terminal valve opening monitoring device, a piston height monitoring device, a piston speed monitoring device, a piston gradient monitoring device, a piston eccentric distance monitoring device and other monitoring devices, high intelligent patrol can be realized, the patrol period is greatly prolonged, the staff patrol frequency is reduced, and the operating safety of the gas tank is improved.

Description

technical field [0001] The invention relates to a gas cabinet, in particular to an intelligent inspection membrane-sealed gas cabinet and an intelligent inspection system for the membrane-sealed gas cabinet. Background technique [0002] For the dry-type gas cabinet piston, its upper part is a restricted space, so the national standard GB6222-2005 "Gas Safety Regulations for Industrial Enterprises" stipulates that "the upper part of the piston should be equipped with an air respirator" to prevent inspection personnel from working. A gas leak caused an accident. The current rubber-membrane-sealed dry-type gas cabinet (hereinafter referred to as the membrane-sealed gas cabinet) needs to inspect the upper part of the piston about once a week. The emergency evacuation of the inspection personnel is to set up manholes at certain heights on the side plate of the air area inside the gas cabinet. , a ladder is set on the support frame system of the rubber film on the piston. When t...

Problems solved by technology

Some detection devices are also disclosed in some patent documents, such as: Patent No. 201420202863 "Wiggins Type Gas Tank Piston Tilt Monitoring Device" discloses a laser rangefinder on the top of the T fence to measure the sealing gap and send a wired transmission signal The method of measuring the tilt of the piston in the gas cabinet monitoring system; the patent No. 201620962761 "Wiggins Gas Cabinet Piston Status Intelligent Monitoring Device" disclosed that the intelligent monitoring of the piston status failed to monitor the early leakage of the sealing rubber membrane interface, and could not solve the problem of extended inspection The problem of cycle; Patent No. 200520033237 "A Piston Tilt Measuring Device for Gas Holder" discloses a method of installing a liquid level signal sensor on the piston to measure the tilt of the piston and sending it out by wire; 》The CO detection signal on the piston is wirelessly transmitted to the top of the cabinet, collected and then sent to the gas cabinet control system, but the sealing film is fixed at the interface (the sealing angle of the side plate of the gas cabinet along the gas cabinet, and the T of the two-stage piston along the T fence). The gas leakage at the lower end of the fence) cannot be detected in time, and it is difficult to give early warning of abnormal working conditions at the rubber membrane compression interface; If the steel wire rope is tensioned, there are problems such as the cable winding is not easy to be easily wound on the guide rail, so it cannot be implemented

[0004] Although some detection devices have been adopted in the existing intelligent inspection membrane-sealed gas holders to replace manual inspections, the inspections of pulleys, bushings, and wire ropes in the leveling device still remain at the level of manual inspections based on experience; Inspection person
