[0002] A gas alarm device is a key piece of equipment to ensure the safety of gas use. It is mainly used to monitor the concentration of gas in the air. It usually consists of a gas sensor, a controller, and an alarm. The gas sensor can sensitively detect the gas composition in the environment. Once the gas concentration reaches the preset alarm threshold, the sensor will transmit a signal to the controller. After receiving the signal, the controller will immediately activate the alarm.

[0003] Chinese patent CN214306554U discloses a protective device for urban gas safety management. The device includes a body and a rear mounting plate. The rear mounting plate has threaded grooves at all four corners. Embedded rods are fixed to both sides of the front end of the rear mounting plate. A display screen is fixed to the front end of the body. An alarm is fixed to the middle of the upper end of the body. Hollow rods are fixed to both sides of the rear end of the body. Several connecting discs are fixed to both sides of the body. An abutment groove is formed on one side of the inner wall of the hollow rod. This protective device for urban gas safety management not only effectively secures the entire body for installation, facilitating installation by external personnel, but also ensures a tighter connection between the external gas pipe and the connecting discs, effectively preventing gas leaks.

[0004] Existing technologies often have the following drawbacks: When gas alarm devices are used in practice, it is inconvenient for staff to hold the detection head to detect gas leaks in confined spaces when the space is narrow, thus reducing the efficiency of gas detection and alarm in confined spaces.

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: an alarm device for urban gas safety management, including an alarm 1, a display 2 fixedly installed on the surface of the alarm 1, a connecting pipe 3 connected to the surface of the alarm 1, a detection head 4 fixedly installed at the other end of the connecting pipe 3, a loudspeaker 5 fixedly installed on the surface of the alarm 1, a support structure 6 provided on the surface of the alarm 1, and a protective structure 7 provided on the surface of the loudspeaker 5.

[0031] The specific design and function of its supporting structure 6 and protective structure 7 will be explained below.

[0032] Reference Figure 1-4 As shown in this embodiment: the support structure 6 includes a connecting block 62 fixedly connected to the side wall of the alarm 1. An L-shaped support rod 63 is slidably connected inside the connecting block 62. An installation ring 68 is fitted onto the side wall of the connecting pipe 3. By setting up the support structure 6, the detection head 4 is flexibly supported, allowing for stable placement of the detection head 4 for gas detection even in confined spaces, avoiding the inconvenience of personnel holding the detection head 4 and improving the efficiency of alarm detection. Several insertion holes 65 are evenly distributed on the side wall of the support rod 63. An insertion rod 66 is slidably connected inside the connecting block 62, with the size of the insertion rod 66 matching the size of the insertion hole 65. The insertion rod 66 is inserted into the corresponding insertion hole 65, fixing the support rod 63. A stop block 64 is fixedly connected to the other end of the insertion rod 66. A spring 67 is fitted onto the surface of the insertion rod 66, with both ends of the spring 67 fixedly connected to the stop block 64 and the connecting block 62, respectively. Under the action of the spring 67, the insertion rod 66 is inserted into the corresponding insertion hole 65. A bolt 69 is threaded into the inside of the installation ring 68. By setting the mounting ring 68 and the bolt 69, the bolt 69 is pressed against the side wall of the detection head 4, thus achieving the fixation between the detection head 4 and the mounting ring 68.

[0033] Reference Figure 1-2 and Figure 5As shown, specifically, the protective structure 7 includes a protective frame 71 fixedly connected to the surface of the loudspeaker 5. The surface of the protective frame 71 has several uniformly spaced first diamond-shaped holes 76. A drawer plate 72 is slidably connected to the inner side of the protective frame 71, and the surface of the drawer plate 72 has several uniformly spaced second diamond-shaped holes 77. By setting up the protective structure 7, flexible shielding and protection of the loudspeaker 5 is facilitated, and the carrying of the loudspeaker 5 is improved. A connecting plate 73 is fixedly connected to the side wall of the drawer plate 72. A screw 75 is threadedly connected to the inside of the connecting plate 73, and the screw 75 is rotatably connected to the inside of the alarm 1. Because the screw 75 is threadedly connected to the connecting plate 73, when the screw 75 rotates, it causes the drawer plate 72 to slide within the protective frame 71. A rotating block 74 is fixedly connected to the other end of the screw 75. Rotating the rotating block 74 causes the screw 75 to rotate.

[0034] Working principle: During operation, the detection head 4 continuously monitors the gas concentration in the air. Once the gas concentration reaches the preset alarm threshold, the detection head 4 transmits a signal to the alarm 1. Upon receiving the signal, the alarm 1 displays relevant alarm information, such as gas leak concentration and alarm time, on the display 2, and simultaneously activates the loudspeaker 5 to sound an alarm, promptly alerting nearby personnel to the gas leak. When using this town gas safety management alarm device, if the detection environment is confined, first operate the support structure 6. By pulling the stop block 64, the insertion rod 66 overcomes the elastic force of the spring 67 and slides into the connecting block 62, disengaging from the insertion hole 65 on the support rod 63. At this point, the support rod can be pulled freely. 63. After extending it to a suitable length, release the stop block 64. Under the action of the spring 67, the insertion rod 66 is inserted into the corresponding insertion hole 65, fixing the support rod 63. At this time, the detection head 4 is supported, which facilitates the stable insertion and detection of the detection head 4 in narrow spaces. By setting the mounting ring 68 and the bolt 69, the bolt 69 is pressed against the side wall of the detection head 4, which can realize the fixation between the detection head 4 and the mounting ring 68, improving the flexibility of the support structure 6. By setting the support structure 6, the detection head 4 is flexibly supported, so that even in narrow spaces, the detection head 4 can be stably placed for gas detection, avoiding the inconvenience of the staff holding the detection head 4 and improving the efficiency of detection alarm.

[0035] If there are concerns that external debris may clog the microphone 5 and affect its sound output while the microphone 5 is in operation, the protective structure 7 can be operated. Rotating the rotating block 74 will cause the screw 75 to rotate. Since the screw 75 is threadedly connected to the connecting plate 73, the rotation of the screw 75 will cause the drawer plate 72 to slide within the protective frame 71. When the second diamond-shaped hole 77 on the drawer plate 72 completely overlaps with the first diamond-shaped hole 76 on the protective frame 71, the ventilation area is maximized, which can effectively prevent debris from entering while ensuring that the sound from the microphone 5 is clearly transmitted. If the environment is dusty, the position of the drawer plate 72 can be adjusted so that the first diamond-shaped hole 76 and the second diamond-shaped hole 77 partially overlap, reducing the ventilation area and further blocking dust to protect the microphone 5. By setting up the protective structure 7, the flexible shielding and protection of the microphone 5 is facilitated, and the safety of carrying the microphone 5 is improved.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
