Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas monitoring, in particular to a combustible volatile matter detection and alarm device. Background Art

[0002] In modern industrial production and daily life, the safety monitoring and management of flammable volatiles are particularly important. Once these flammable volatiles, such as natural gas, leak and accumulate in a confined space or near a heat source, they can easily cause fires or even explosions, causing immeasurable damage to personnel safety, equipment integrity, and the environment. Therefore, in order to prevent such accidents, combustible gas alarms are installed during production operations for detection and alarm.

[0003] Most of the flammable gas alarms commonly seen on the market are wall-mounted structures. Ear plates are provided on the body of the flammable gas alarm. The flammable gas alarm can be installed and fixed by passing bolts through the ear plates and fixing them to the wall. However, although this installation method has the advantage of reliable installation, in actual use, this fixing method has the following disadvantages. Specifically: During the use of the flammable gas alarm, in order to ensure the working performance of the flammable gas alarm, the inspection, maintenance or replacement of the flammable gas alarm is indispensable, and this operation inevitably requires the disassembly and assembly of the flammable gas alarm. The traditional bolt fixing method is not only very inconvenient when disassembling and assembling the flammable gas alarm, but also causes great damage to the fixing surface. In view of this, we propose a flammable volatile matter detection and alarm device. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] This embodiment provides a technical solution:

[0028] In this embodiment, a positioning rod 14 is coaxially fixed at the center of the mounting plate 12, a positioning hole 201 is provided at the center of the housing 20, and the positioning rod 14 is plugged into the positioning hole 201. The positioning rod 14 and the positioning hole 201 are arranged between the detector body 1 and the housing 20 to play a positioning role, thereby improving the installation convenience of the detector body 1.

[0029] In this embodiment, the left and right ends of the housing 20 are fixed with connecting edges 21, and two fixing holes 211 for passing bolts are provided on the connecting edges 21. The setting of the fixing holes 211 facilitates passing bolts to install and fix the housing 20 to a fixed surface such as a wall.

[0030] In this embodiment, the movable seat 22 and the clamping plate 23 are integrally formed, and the size of the movable seat 22 matches the size of the inner cavity of the housing 20. The integrally formed movable seat 22 and clamping plate 23 have better connection strength, ensuring the connection stability of the movable seat 22 and the clamping plate 23, thereby ensuring the fixing effect of the clamping plate 23 on the plug board 13. The matching size is conducive to the smooth lifting and lowering of the movable seat 22.

[0031] In this embodiment, the mounting plate 12 and the plug plate 13 are integrally formed, and both the mounting plate 12 and the plug plate 13 are made of aluminum alloy.

[0032] In this embodiment, mounting bolts are provided at both ends of the mounting plate 12, and the mounting bolts are threadedly connected to the detector body 1. This mounting method has the advantage of reliable mounting, and ensures the reliability of the mounting plate 12.

[0033] In this embodiment, the bottom end of the connecting rod 24 is coaxially keyed to a limiting block 25, and the diameter of the limiting block 25 is larger than the diameter of the connecting rod 24. The limiting block 25 limits the connecting rod 24, and further limits the movable seat 22.

[0034] It should be added that a combustible gas detector is a device used to monitor the concentration of combustible gases in the environment. It can detect a variety of combustible gases, such as methane, ethane, propane, hydrogen, etc., and issue an alarm when the gas concentration reaches a preset safety threshold to prevent dangerous events such as fire and explosion. The working principle of the combustible gas detector is mainly divided into two types, one is a detector based on the principle of chemical reaction, and the other is a detector based on the principle of thermal conductivity; and the alarm 10 and sensor 11 in this embodiment are both conventional structures of combustible gas detectors, and their principles are well known to those in the field and will not be elaborated here.

[0035] When disassembling the detector body 1, the user first presses the pressure plate 27 downward, and the pressure plate 27 drives the two connecting rods 24 to move downward, and the connecting rods 24 drive the movable seat 22 to move downward, and the movable seat 22 compresses the spring 26 downward. At this time, the movable seat 22 drives the card plate 23 to disengage from the card slot 131, and the restriction of the card plate 23 on the plug plate 13 is released. Then the user pushes the detector body 1 to the front side, and when the plug plate 13 disengages from the slot 202, the detector body 1 can be disassembled.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
