Description

TECHNICAL FIELD

[0001] The utility model relates to gas alarm technical field, concretely is an easily replaced corridor gas alarm. BACKGROUND

[0002] Gas alarm is a detection instrument for monitoring and alarming gas leakage, which senses the concentration level of specific type gas in the environment in real time through sensor system. This process is based on detection technology and can accurately capture the trace gas molecular changes in the air. When the concentration of these gases reaches or exceeds the preset safety threshold, the gas alarm will immediately start the alarm mechanism, and through the sound and light signal or other preset alarm mode, it will timely notify the relevant personnel to take necessary measures to prevent fire, explosion, poisoning and other serious safety accidents caused by gas leakage.

[0003] Corridor, as a key passageway connecting different areas around the garbage disposal pit, its internal environment is often relatively complex and changeable, full of various factors affecting the performance of gas alarm, including but not limited to suspended dust particles in the air, ubiquitous water vapor and possible corrosive substances. These environmental factors not only pollute and damage the precise sensors of gas alarm, but also gradually erode its internal electronic components, thus significantly shortening the service life of the alarm.

[0004] In order to ensure that the gas monitoring work in the corridor can be carried out continuously and accurately, the gas alarm must maintain high sensitivity and reliability. Once the alarm is disturbed or damaged by environmental factors, resulting in performance degradation or failure, it needs to be replaced or repaired immediately to ensure that the alarm can be issued quickly in emergency situations such as gas leakage, reminding relevant personnel to take necessary measures.

[0005] However, the main installation mode of the gas alarm widely used in the current market for corridor environment generally adopts bolt fixing connection. Although this installation mode ensures the stability of the alarm in the corridor to a certain extent, when the bolt is installed, the installer needs to prepare various tools including screwdriver, electric drill, wrench and sufficient fasteners such as bolts and nuts in advance. In addition, in order to ensure that the gas alarm can be accurately installed at the predetermined position, the installer also needs to accurately measure and mark the installation position, which undoubtedly increases the preparation workload before installation. Secondly, from drilling, installing expansion plugs or embedded parts, to aligning the gas alarm with the installation hole and fixing it with bolts, each step needs to be carefully operated by the installer, and any carelessness may cause installation failure or damage to the alarm. The whole installation process is complicated and time-consuming. Furthermore, when the gas alarm needs to be maintained or replaced, the installer needs to loosen and remove the bolts one by one. This process not only consumes time and effort, but also causes damage to the alarm or installation position due to rust or over-tightening of the bolts caused by long-term use.
