Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas fire extinguishing equipment technology, and in particular to an intelligent wireless automatic gas fire extinguishing alarm host. Background Technology
[0002] The intelligent wireless automatic gas fire extinguishing alarm control panel has control, alarm, communication, and display functions. By connecting to the on-site gas fire extinguishing device, it receives environmental data transmitted by the device, and the CPU analyzes and processes the data to determine if any exceedances are detected, triggering an audible and visual alarm.
[0003] Currently, alarm control panels on the market only have one 485 bus for communication. When there are too many connected devices, this can easily cause communication congestion, data anomalies, and reporting delays. There are also no spare communication interfaces, making it impossible to switch to a backup line in case of communication failure. Furthermore, existing technology typically features circular holes at the bottom of the control panel for cable routing. However, due to the lack of a sealing structure, dust and other foreign objects can enter the device through these holes, potentially interfering with normal operation and increasing the difficulty and frequency of maintenance. In humid environments, moisture can seep into the device through these holes, causing circuit board corrosion or short circuits, thus affecting the device's performance and lifespan.
[0004] To address the aforementioned shortcomings, an intelligent wireless automatic gas fire extinguishing alarm control panel is provided. Utility Model Content

[0009] Preferably, the component that drives the stopper disc to move vertically includes a rotating disk rotatably connected to the bottom of the sheet metal housing, and a limiting assembly. A rotating shaft is coaxially fixed on the rotating disk, a protrusion is formed on the inner wall of the stopper disc, and a slide rail is formed on the side wall of the rotating shaft to slide in conjunction with the protrusion. The slide rail has a spiral structure.
[0010] Preferably, the limiting assembly includes a sliding arm slidably disposed at the bottom of the sheet metal housing, and the sliding arm is slidably embedded in the rotary table. A positioning rod is fixedly disposed at the bottom of the sheet metal housing, and an insertion port for the positioning rod is formed in the sliding arm.
[0011] Preferably, the socket is composed of a flared transition groove and a circular hole groove that is adapted to the socket.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: an intelligent wireless automatic gas fire extinguishing alarm host, including a sheet metal shell 1. An air circuit breaker 3, a power filter 4, and a data concentrator 5 are installed in the sheet metal shell 1 via a track 2. An LCD touch screen 6 is installed at the outer end of the sheet metal shell 1. An alarm indicator light 7 is installed at the bottom of the sheet metal shell 1. A perforated ring 8 for wiring is provided at the inner bottom of the sheet metal shell 1, and a rubber ring 9 is provided in the perforated ring 8. A gas pressure control structure for controlling the inflation state of the rubber ring 9 is provided in the sheet metal shell 1. The data concentrator 5 has four RS485 communication ports.
[0023] The red alarm indicator light 7 is mounted in the center of the top of the casing and secured with 3M adhesive. The 10-inch LCD touchscreen 6 is embedded in a recess in the center of the front of the sheet metal casing 1, and is secured with screws by mounting brackets around it. The rail 2 is installed inside the sheet metal casing 1 and secured to the center of the back with screws. The air circuit breaker 3, power filter 4, and data concentrator 5 are mounted sequentially on the rail from left to right and secured with clips. All power and communication cables are connected using multi-strand, multi-core national standard pure copper flexible wire. All power and communication terminals use screw-type and pluggable terminal blocks.
[0024] The built-in 4-bus data concentrator 5 supports up to 256 devices per bus. The host can send configuration parameters to all devices with one click, and the device communication address can be modified individually without the need for batch debugging tools. This can improve the host's 485 communication quality and resolve 485 communication anomalies.
[0025] The LCD touch screen 6 is powered directly by AC 220V without the need for an external power adapter, saving internal space. At the same time, the addition of a power filter 4 can effectively improve the host's anti-interference ability in complex environments, ensuring stable operation of the host and thus improving the host's electromagnetic compatibility.
[0026] The LCD touchscreen 6 directly adopts a touchscreen that integrates voice, touch, knob, and button functions. It has two built-in relay outputs, three button inputs, and built-in speaker and voice broadcast functions to meet the different functional needs of customers in various scenarios and solve the problem of limited touchscreen functionality.
[0027] The fault log interface now includes alarms for device offline and communication anomalies, resolving the issue of missing device status data in the reported data. Functionally, a fire feedback output has been added, enabling fire alarm linkage. A silencing and reset function has also been added to prevent accidental activation of fire extinguishing devices and allow for device restart. Furthermore, the simulated smoke levels reported by the fire extinguishing devices are now directly converted into realistic concentration values and displayed on the screen, addressing the issue of the main unit's limited functionality.
[0028] After the wire passes through the hole ring 8 and is led outward, the expansion of the rubber ring 9 is controlled by the air pressure control structure. The expanded rubber ring 9 seals the gap between the wire and the hole ring 8. This design can effectively prevent dust, foreign objects, moisture and water from entering the equipment through the wiring hole, thus improving the protective performance of the equipment.
[0029] Specifically, such as Figure 3 and Figure 4 As shown, the air pressure control structure includes an air cylinder 10 fixed inside the bottom of the sheet metal housing 1, a stopper disc 11 slidably connected inside the air cylinder 10, and an assembly that drives the stopper disc 11 to move vertically. An air pipe 19 is connected between the air cylinder 10 and the rubber ring 9.
[0030] By controlling the stopper disc 11 to move downward along the air cylinder 10, the air in the air cylinder 10 is forced into the rubber ring 9 through the air pipe 19, thereby causing the rubber ring 9 to expand and fill the gap between the line and the hole ring 8.
[0031] The components that drive the stopper disc 11 to move vertically include a rotating disc 15 rotatably connected to the bottom of the sheet metal housing 1, and a limiting assembly. A rotating shaft 13 is coaxially fixed on the rotating disc 15. A protrusion 12 is formed on the inner wall of the stopper disc 11. A slide rail 14 is formed on the side wall of the rotating shaft 13 to slide in coordination with the protrusion 12. The slide rail 14 has a spiral structure.
[0032] By rotating the rotary disk 15, the rotary shaft 13 rotates synchronously. During this process, the spiral slide rail 14 acts on the protrusion 12, driving the stopper disc 11, which is fixed to the protrusion 12, to move vertically along the air cylinder 10. To ensure effective transmission of the slide rail 14 to the protrusion 12, the stopper disc 11 needs to be slidably connected to the air cylinder 10 via a spline to limit the rotation of the stopper disc 11 relative to the air cylinder 10.
[0033] The limiting assembly includes a sliding arm 16 that is slidably disposed at the bottom of the sheet metal housing 1, and the sliding arm 16 is slidably embedded in the rotary table 15. A positioning rod 18 is fixedly disposed at the bottom of the sheet metal housing 1, and an insertion port 17 is formed in the sliding arm 16 to cooperate with the positioning rod 18.
[0034] By pulling the handle, the sliding arm 16 slides along the rotating disk 15. When the positioning rod 18 disengages from the socket 17, the user can pull the sliding arm 16 to drive the rotating disk 15 to rotate the rotating shaft 13. After adjusting the bulging state of the rubber ring 9, the socket 17 is reconnected with the positioning rod 18 to restrict the arbitrary rotation of the rotating disk 15.
[0035] The socket 17 consists of a flared transition groove and a matching circular slot. The flared transition groove provides a gradually narrowing structure, making it easier for the positioning rod 18 to be inserted and fixed in the socket 17, ensuring the stability and reliability of the connection. Simultaneously, the circular slot design ensures the fit between the positioning rod 18 and the socket 17, resulting in a tighter connection and improving the overall structural stability and durability.
[0036] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
