Embodiment 1

[0034] Embodiment 1: as Figure 8 As shown, the explosion-proof torsion probe 4 is externally equipped with an explosion-proof light source 9 to supplement the lack of light in the gas cabinet. A vertical reference line 3 is provided from top to bottom in the side wall of the gas cabinet 1. The color of the vertical reference line 3 is clearly distinguished from the background color of the inner wall of the gas cabinet 1, which is convenient for image analysis and processing of the explosion-proof torsion probe 4. The width of the line is It can be about 5-10mm; the distance measuring circuit is installed in the explosion-proof torsion probe 4, and the distance between the position of the explosion-proof torsion probe 4 and the side wall of the gas cabinet 1 is obtained, and the offset result is corrected by using this distance value; the distance measurement circuit can use : Laser ranging, ultrasonic, infrared, radar, etc.

Embodiment 2

[0035] Embodiment 2: as image 3 and Figure 9 As shown, the explosion-proof torsion probe 4 is externally equipped with an explosion-proof light source 9 to supplement the lack of light in the gas cabinet. Two vertical reference lines 3 are arranged from top to bottom in the side wall of the gas cabinet 1. The color of the vertical reference lines 3 is clearly distinguished from the background color of the inner wall of the gas cabinet 1, which is convenient for the image analysis and processing of the explosion-proof torsion probe 4; the width of the lines It can be about 5-10mm; the image analysis software and displacement result processing software are slightly different from Embodiment 1. The explosion-proof torsion probe 4 automatically compensates and adjusts the result according to the actual width of the two vertical reference lines 3 and the obtained image width.

Abstract

The invention discloses a monitoring device and method for the piston torque of a rubber membrane seal gas holder. A non-contact displacement measurement method is adopted, multiple anti-explosion torque probes are used for monitoring the displacement, and data of the overall piston torque are obtained finally. According to the device, one or two vertical reference lines are arranged at corresponding positions of measuring points of the inner wall of the gas holder, multiple sets of anti-explosion torque probes, a corresponding image processing and communication device and a corresponding data receiving and processing device of a control center are configured. The data receiving and processing device receives torsion capacity data of the anti-explosion torque probes, comprehensive analysis and calculation are conducted, and analog display of the piston torque, torque capacity current output of all monitoring points and current output of the overall torque capacity of a whole piston are given. The monitoring device and method have the beneficial effects that continuous online monitoring is conducted on the piston torsion capacity of the rubber film seal gas holder, continuous online accurate torque capacity data are obtained, the running state of the piston can be effectively mastered, and great benefits are achieved on production safety of running of the gas holder and prevention of the occurrence of the abnormal state of the piston.

Description

technical field [0001] The invention relates to a gas cabinet monitoring device, in particular to a rubber membrane-sealed gas cabinet piston torsion monitoring device and method. Background technique [0002] Rubber membrane-sealed dry gas holders are widely used in metallurgy, municipal, chemical and other fields, mainly for the storage and comprehensive utilization of gas or toxic gases. [0003] The body of the rubber membrane-sealed dry-type gas cabinet is a cylinder with a vault. It consists of bottom plate, column, side plate, piston, sealing mechanism, cabinet top and corridor. A group of pistons that can move up and down are installed in the cylinder, and a sealing device is installed between the pistons and the side plates. [0004] The working principle of the rubber membrane gas cabinet is: when the gas pressure of the external pipe network is higher than the pressure inside the cabinet, a large amount of gas will enter the gas cabinet, push the piston to rise ...
