Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Reference Figures 1-3 An embodiment provided by the utility model: a civil air defense alarm anti-mistake sounding detection device, including main plate 1, the positioning plate 10 of fixed connection in the front side of main plate 1, the rear side of shell 2 is provided with positioning groove, the positioning plate 10 is arranged in the inside of positioning groove, the plug-in shell 3 of fixed connection in the outer wall of main plate 1 and shell 2, the inner wall of adjacent two plug-in shell 3 is provided with plug-in groove, the plug-in shaft 7 is arranged in the inside of plug-in groove, to be used for the installation between main plate 1 and shell 2, the rear side of main plate 1 is fixedly connected with fixed block 9, the plug 13 of fixed connection in the bottom side of fixed block 9, the outer wall of fixed rod 11 is slidably connected with clamping block 14, the plug 13 is arranged between two clamping blocks 14, the outer wall of fixed rod 11 is provided with spring 12, the rear side of C-shaped fixed shell 15 is fixedly connected with mounting plate 8, the inner wall of C-shaped fixed shell 15 is fixedly connected with fixed rod 11, the top end of main plate 1 is provided with buzzer 6;

[0025] Specifically, the front side of the main plate 1 is inserted into the positioning groove on the rear side of the shell 2 through the positioning plate 10, so as to realize preliminary accurate positioning and fix the relative position, lay the foundation for subsequent assembly. Subsequently, the main plate 1 and the plug-in shell 3 on the outer wall of the shell 2 are aligned with each other, the plug-in shaft 7 is inserted into the plug-in groove of the adjacent two plug-in shells 3, and stable connection is completed. At this time, the cover plate 5 on the top side of the front plug-in shell 3 is automatically covered on the plug-in shaft 7 under the action of the torsional spring, preventing it from accidentally coming out, and further ensuring the stability of the connection. When the main plate 1 needs to be overhauled and maintained, the main plate 1 and the shell 2 can be disassembled for quick overhaul by reverse operation. When installing and fixing, first, the mounting plate 8 is fixed at the required position through bolts, then the clamping block 14 is slid outward to loosen the plug 13 by pulling the pull shaft 4 against the elastic force of the spring 12, and the separation of the main plate 1 and the mounting structure is completed. Then, the plug 13 of the required civil air defense alarm is inserted between the two clamping blocks 14, and the spring 12 on the outer wall of the fixing rod 11 is compressed. When the inclined surfaces of the clamping block 14 and the fixing rod 11 are no longer in contact, the spring 12 resets to clamp the clamping block 14 and the fixing rod 11, completing the installation of the alarm. The buzzer 6 located at the top end of the main plate 1 is a key alarm sounding component. When the civil air defense alarm system has abnormal conditions that may cause false buzzing, such as circuit failure, signal interference, false triggering instructions, etc., the detection circuit inside the false buzzing detection device will monitor the parameters of the system in real time, integrated in the related modules of the main plate 1. Once an abnormality is detected, a trigger signal is sent to the buzzer 6, the buzzer 6 emits a sound, and the staff is warned to promptly troubleshoot the alarm system to avoid false buzzing and ensure the reliability and accuracy of the civil air defense alarm system, so that it can normally play a warning function at critical moments.

[0026] Referring to Figures 3-5 , one end of the spring 12 connected to the clamping block 14 and the other end of the spring 12 connected to the inner wall of the C-shaped fixed shell 15, the top side of the front plug-in shell 3 is connected with the cover plate 5 through the torsional spring, the bottom side of the cover plate 5 is arranged on the top side of the plug-in shaft 7, the outer wall of the clamping block 14 is fixedly connected with the pull shaft 4, and the pull shaft 4 is slidingly connected to the top end inner wall of the C-shaped fixed shell 15;

[0027] Specifically, the elastic force of the spring 12 on the clamping block 14 tightly connects the main plate 1 and the C-shaped fixed shell 15, effectively avoiding the shaking or displacement of the main plate 1 on the mounting structure, improving the stability and reliability of the entire device, and separating the main plate 1 and the C-shaped fixed shell 15 by pulling the pull shaft 4, facilitating disassembly and maintenance of the device, and reducing maintenance time and cost.

[0028] Working principle: the front side positioning plate 10 of the main plate 1 is inserted into the positioning groove on the rear side of the shell 2, the preliminary accurate positioning of the main plate 1 and the shell 2 is realized, and the relative position of them is fixed, which provides the basis for subsequent assembly operation. Subsequently, the plug-in shells 3 on the outer walls of the main plate 1 and the shell 2 are aligned with each other, the plug-in shaft 7 is inserted into the plug-in groove of the adjacent two plug-in shells 3, and the stable connection of the main plate 1 and the shell 2 is completed. At this time, the cover plate 5 on the top side of the front plug-in shell 3 is automatically covered on the plug-in shaft 7 under the action of the torsional spring, preventing it from accidentally falling out, and further ensuring the stability of the connection. When the main plate 1 needs to be overhauled and maintained, only the reverse operation is needed, that is, the main plate 1 and the shell 2 can be quickly disassembled, and the overhaul work is conveniently and quickly carried out. When installing and fixing, the mounting plate 8 is first fixed at the required position by bolts. Then, pull the pull shaft 4, make the clamping block 14 slide outward against the elastic force of the spring 12, loosen the plug 13, and thus complete the separation of the main plate 1 and the mounting structure. Then, the plug 13 of the required civil air defense alarm is inserted between the two clamping blocks 14, and the spring 12 on the outer wall of the fixing rod 11 is compressed. When the inclined surfaces of the clamping block 14 and the fixing rod 11 are no longer in contact, the spring 12 resets and pushes the clamping block 14 to engage with the fixing rod 11, thereby completing the installation of the alarm.

[0029] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
