[0002] Gas fuels are a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. There are many types of gas fuels, mainly including natural gas, manufactured gas, liquefied petroleum gas (LPG), biogas, and coal gas. Compared with developed countries, my country's gas supply industry started relatively late, and the gas distributed mainly includes coal gas, LPG, and natural gas.

[0003] In gas pipeline networks, it is necessary to inspect gas pipeline connections or valves to prevent gas leaks. This requires the use of gas leak detectors. However, most existing gas leak detectors have a one-piece casing, which makes it inconvenient to inspect and repair the internal monitoring devices, causing inconvenience in use. Utility Model Content

[0004] To address the problem that most existing gas leak detector housings are one-piece structures, making it inconvenient to inspect and repair the internal monitoring devices and causing inconvenience to users, this application provides a gas leak detector housing.

[0006] A gas leak detector housing includes a first housing and a second housing, which are detachably connected. Both ends of the first and second housings are symmetrically fitted with arc-shaped baffles that communicate with their interiors. A mounting base is provided within each arc-shaped baffle, and a sealing ring is installed on one side of each mounting base. An arc-shaped groove is formed on the inner wall of each arc-shaped baffle, and multiple sets of elastic elements connected to the sealing ring are installed at equal intervals within the arc-shaped groove. A gas sensor is installed at the bottom of the first housing, and a control box and an alarm are symmetrically mounted on its outer surface.

[0007] Preferably, the outer surfaces of the first housing and the second housing are respectively equipped with fixing plates, and the fixing plates are fixed together by multiple bolts.

[0008] Preferably, a plurality of guide rods are symmetrically arranged on the outer side of one end of the first housing, and a plurality of guide holes matching the guide rods are symmetrically opened on the outer side of one end of the second housing.

[0009] Preferably, a controller is installed inside the control box, and the controller is electrically connected to the gas sensor and the alarm.

[0010] Preferably, the elastic element includes a sleeve rod fixed in an arc-shaped groove and a movable rod slidably sleeved in the sleeve rod. A spring is fixedly provided in the sleeve rod, the other end of the spring is connected to the movable rod, and the other end of the movable rod is connected to a fixed seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The housing of this gas leak detector is assembled from a first housing and a second housing, which are directly and detachably fixed together. This facilitates installation and disassembly, making it easier to inspect and maintain the internal monitoring devices and providing convenience for users. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution:

[0021] A gas leak detector housing includes a first housing 1 and a second housing 2, which are detachably connected. Both ends of the first housing 1 and the second housing 2 are symmetrically equipped with arc-shaped baffles 3 that communicate with their interiors. A mounting base 4 is provided inside the arc-shaped baffle 3, and a sealing ring 5 is installed on one side of the mounting base 4. An arc-shaped groove is formed on the inner wall of the arc-shaped baffle 3, and multiple sets of elastic elements connected to the sealing ring 5 are installed at equal intervals in the arc-shaped groove. A gas sensor 6 is installed at the bottom of the first housing 1, and a control box 7 and an alarm 8 are symmetrically installed on its outer surface.

[0022] In use, the first housing 1 and the second housing 2 are fitted onto the gas pipeline connection or valve and fixed in place. A sealing ring 5 is installed inside the arc-shaped baffle 3 to seal the gas pipeline. During detection, the gas sensor 6 can detect the gas. When gas leaks from the pipeline connection or valve, the leaked gas can enter the first housing 1 and the second housing 2. The gas sensor 6 can detect the gas inside the first housing 1 and the second housing 2. When the gas sensor 6 detects the gas, the alarm 8 will sound an alarm, which can promptly alert nearby and surrounding personnel, thus achieving the purpose of gas leak monitoring.

[0023] Fixing plates 9 are respectively installed on the outer surfaces of the first housing 1 and the second housing 2. The fixing plates 9 are fixed together by multiple bolts, which facilitates the installation and disassembly of the first housing 1 and the second housing 2, thereby facilitating the inspection and maintenance of the internal monitoring devices and bringing convenience to the user.

[0024] Multiple guide rods 10 are symmetrically arranged on the outer side of one end of the first housing 1, and several guide holes 11 matching the guide rods 10 are symmetrically opened on the outer side of one end of the second housing 2. During installation, the guide rods 10 are aligned with the guide holes 11 and inserted to play a guiding role. At this time, the first housing 1 and the second housing 2 are completely overlapped, which improves the stability of installation.

[0025] The control box 7 contains a controller, which is electrically connected to the gas sensor 6 and the alarm 8. When the gas sensor 6 detects gas, it sends a signal to the controller, which then activates the alarm 8 to sound an alarm. It should be noted that the devices described above are all well-known to those skilled in the art and are all conventional methods or common knowledge, so they will not be described in detail here.

[0026] The elastic element includes a sleeve rod 12 fixed in an arc groove and a movable rod 14 slidably sleeved in the sleeve rod 12. A spring 13 is fixedly installed in the sleeve rod 12. The other end of the spring 13 is connected to the movable rod 14, and the other end of the movable rod 14 is connected to the mounting base 4. During installation, the elastic force of the spring 13 allows the sealing ring 5 to fit tightly against the gas pipeline, thereby improving the sealing performance of the installation.

[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0028] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model.
