Abstract

The invention relates to the technical field of natural gas monitoring equipment, in particular to a safety device for monitoring natural gas leakage in a closed space in real time. The device comprises a supporting assembly, a fixing plate and a monitoring assembly. An electric cylinder for adjusting the height of the monitoring assembly is arranged on the fixing plate; the mounting frame is slidably arranged on the arc-shaped fixing seat A through a sliding block, and a motor A is arranged on the mounting frame; the gear A is arranged on a rotating shaft of the motor A and is in meshed connection with the arc-shaped fixing seat A; the arc-shaped movable seat is arranged on the arc-shaped fixed seat B in a sliding manner; a cavity communicated with the vent hole is formed in the arc-shaped movable seat; the natural gas detector and the micro fan are arranged in the arc-shaped movable seat and the cavity; the control valve is arranged on the arc-shaped movable seat; the motor B is arranged on the arc-shaped fixing seat B, and the gear B is arranged on a rotating shaft of the motor B and is meshed with the teeth. The system can perform accurate real-time monitoring, effectively prevents natural gas leakage, can automatically and quickly find out leakage points and maintain, and is wide in application range and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of natural gas monitoring equipment, in particular to a safety device for real-time monitoring of natural gas leakage in confined spaces. Background technique [0002] Natural gas needs to be stored after extraction, and accidents of natural gas leakage often occur due to external environmental factors and weak pipeline connections. Natural gas storage equipment will also cause natural gas leakage due to reasons such as poor sealing and aging of sealing parts. Natural gas is easy to mix with air after leakage, and explosion accidents may occur when encountering open flames or electric sparks. Therefore, real-time monitoring of natural gas storage tanks to detect whether there is natural gas leakage is of great significance to ensure the safe production of natural gas. [0003] Traditional natural gas leak detection is usually carried out by hand-held natural gas analyzers, which not only consumes a lot of h...
