Description

Technical Field

[0001] This utility model relates to the field of fire protection distribution cabinet technology, and in particular to an automatic fire extinguishing device for fire protection distribution cabinet. Background Technology

[0002] Fire protection distribution cabinets are electrical devices specifically designed to provide power distribution, control, and protection for fire protection equipment. They ensure the reliable operation of fire protection equipment during a fire and are an important component of the fire protection electrical system. They are generally made of metal and have good protective performance, being dustproof, moisture-proof, and fireproof, protecting internal electrical components from external environmental influences.

[0003] A search of Chinese patent publication number "CN217607225U" reveals a "fire-fighting power distribution cabinet". This cabinet allows a nut to be rotated clockwise, causing it to move between two sets of brackets along a screw, applying a pushing force to the mounting plate. The mounting plate then moves upwards along a vertical plate via a groove and sliding groove. As the mounting plate moves upwards, it compresses a spring, which in turn applies a downward pushing force to the mounting plate. This, combined with the nut, effectively limits the mounting plate's position, improving its stability. Through this operation, operators can adjust the positions of the two sets of mounting plates inside the cabinet as needed, facilitating the installation of electrical components of different sizes and effectively improving the practicality of the power distribution cabinet.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the distribution cabinet is in use, it is not equipped with an automatic fire extinguishing structure linked to the cabinet, which makes it impossible to generate an effective fire suppression mechanism when a fire is triggered. As a result, the overall fire protection level is limited and its practicality is insufficient, which needs to be improved. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an automatic fire extinguishing device for fire distribution cabinets, which solves the technical problem of insufficient practicality of existing devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An automatic fire extinguishing device for a fire distribution cabinet includes a fire distribution cabinet body, wherein T-shaped grooves are symmetrically opened on the side wall of the fire distribution cabinet body;

[0010] Each of the T-shaped slots is equipped with an automatic fire extinguishing structure that is slidably installed inside.

[0011] The automatic fire extinguishing structure includes sliders, each of which is partially exposed outside the fire distribution cabinet body. A rectangular frame is fixedly installed between each pair of sliders. A fire extinguishing sprayer is provided inside each of the two rectangular frames. A U-shaped rod is provided at the lower end of each of the two rectangular frames. An electric push rod is provided at the lower end of the fire distribution cabinet body. A connecting rod is fixedly installed between each of the two U-shaped rods and the output shaft of the electric push rod. The movement of the output shaft of the electric push rod can drive the sliders and rectangular frames to slide along the T-shaped groove through the connecting rod and the U-shaped rod.

[0012] Preferably, the lower end of the fire-fighting power distribution cabinet body is provided with a multi-functional module unit, and the fire-fighting power distribution cabinet body is provided with a smoke sensor. The multi-functional module unit can provide power to the fire extinguishing sprayer, electric push rod and smoke sensor. The smoke sensor can detect whether the fire-fighting power distribution cabinet body is in a fire state.

[0013] Preferably, the fire-fighting power distribution cabinet body has a hinged cabinet door, and the fire-fighting power distribution cabinet body has symmetrical through slots. Both through slots are located inside the T-shaped slots. Both through slots have rectangular slots on their inner walls. Both rectangular slots have rectangular frames magnetically connected inside them. Both rectangular frames have filters on their inner sides. Both filters are located at the through slots.

[0014] (III) Beneficial Effects

[0015] Firstly, when a fire occurs inside the fire distribution cabinet, its automatic fire extinguishing mechanism will be activated. The output shaft of the electric push rod will retract, driving the U-shaped rod to move upward along the T-shaped groove via the connecting rod. When the output shaft of the electric push rod retracts to the limit position, the rectangular frame will block the through groove, and the fire extinguishing sprayer will be activated, spraying high-pressure fire extinguishing medium towards the filter screen. At this time, the rectangular frame and the filter screen will detach from the through groove and the rectangular groove due to the radial force. At the same time, the fire extinguishing sprayer will carry out a comprehensive fire extinguishing operation inside the fire distribution cabinet. During this process, by blocking the only heat dissipation channel through the through groove, the contact channel between oxygen and the fire source inside the cabinet is effectively blocked, thereby significantly improving the fire extinguishing efficiency.

[0016] Secondly, by setting a through groove in the fire protection distribution cabinet body and opening a rectangular groove in its inner wall, and configuring a combination structure of magnetic rectangular frame and filter screen, it can effectively prevent dust from entering the cabinet and interfering with the operation of components, maintain normal heat dissipation function, facilitate maintenance work, and when the fire extinguishing sprayer is activated, the radial force of its high-pressure spray medium can cause the filter screen to actively and automatically detach from the through groove, ensuring that the fire extinguishing medium covers the cabinet space without obstruction, thereby eliminating the technical hidden dangers that hinder the fire extinguishing effect.

[0024] This application provides an automatic fire extinguishing device for a fire distribution cabinet, effectively solving the technical problem of insufficient practicality of existing devices. When a fire occurs inside the fire distribution cabinet, its automatic fire extinguishing structure will be activated. The output shaft of the electric push rod will retract, driving the U-shaped rod to move upward along the T-groove via a connecting rod. When the output shaft of the electric push rod retracts to its limit position, the rectangular frame will block the through groove, and the fire extinguishing sprayer will be activated, spraying high-pressure fire extinguishing medium towards the filter screen. At this time, the rectangular frame and the filter screen will detach from the through groove and the rectangular groove due to the radial force. Simultaneously, the fire extinguishing sprayer will spray the fire distribution cabinet body. The internal fire suppression system employs a comprehensive, all-encompassing approach. During this process, the single heat dissipation channel is sealed, effectively blocking the contact between oxygen and the fire source within the cabinet, thus significantly enhancing fire suppression efficiency. Furthermore, by incorporating a channel within the fire control cabinet body and creating a rectangular groove on its inner wall, a combination of a magnetic rectangular frame and a filter screen is installed. This effectively prevents dust from entering the cabinet and interfering with component operation, while maintaining normal heat dissipation. It also facilitates maintenance. When the fire suppression sprayer is activated, the radial force of its high-pressure jet causes the filter screen to automatically detach from the channel, ensuring unobstructed coverage of the cabinet space by the fire suppression medium, thereby eliminating any technical risks that could hinder fire suppression effectiveness.

[0025] Example

[0026] like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient practicality of existing devices. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an automatic fire extinguishing device for a fire distribution cabinet, including a fire distribution cabinet body 11, with T-shaped grooves 12 symmetrically opened on the side wall of the fire distribution cabinet body 11;

[0028] Each T-shaped groove 12 is equipped with an automatic fire extinguishing structure that slides inside.

[0029] The automatic fire extinguishing structure includes sliders 13, each slider 13 being partially exposed outside the fire distribution cabinet body 11. Each slider 13 is fixedly installed with a rectangular frame 14 between each pair of sliders 13. Fire extinguishing sprayers 15 are provided inside the two rectangular frames 14. U-shaped rods 16 are provided at the lower ends of the two rectangular frames 14. Electric push rods 17 are provided at the lower ends of the fire distribution cabinet body 11. Connecting rods 18 are fixedly installed between the two U-shaped rods 16 and the output shaft of the electric push rods 17. The movement of the output shaft of the electric push rods 17 can drive the sliders 13 and rectangular frames 14 to slide along the T-shaped groove 12 through the connecting rods 18 and the U-shaped rods 16.

[0030] When a fire occurs inside the fire distribution cabinet body 11, its automatic fire extinguishing structure will be activated. The output shaft of the electric push rod 17 will retract, driving the U-shaped rod 16 to move via the connecting rod 18. This will push the slider 13 and the rectangular frame 14 to slide upward along the T-shaped groove 12. When the output shaft of the electric push rod 17 retracts to the limit position, the rectangular frame 14 will block the through groove 23. Immediately, the fire extinguishing sprayer 15 will be activated, spraying high-pressure fire extinguishing medium towards the filter screen 26. At this time, the rectangular frame 25 and the filter screen 26 will detach from the through groove 23 and the rectangular groove 24 due to the radial force. Simultaneously, the fire extinguishing sprayer 15 will carry out a comprehensive fire extinguishing operation inside the fire distribution cabinet body 11. During this process, by blocking the only heat dissipation channel through groove 23, the contact channel between oxygen and the fire source inside the cabinet is effectively blocked, thereby significantly improving the fire extinguishing efficiency.

[0031] The lower end of the fire distribution cabinet body 11 is provided with a multi-functional module unit 19, and the fire distribution cabinet body 11 is provided with a smoke sensor 21.

[0032] The multi-functional module unit 19 can power the fire extinguishing sprayer 15, the electric push rod 17 and the smoke sensor 21. The smoke sensor 21 can detect whether the inside of the fire distribution cabinet body 11 is on fire.

[0033] The fire distribution cabinet body 11 has a cabinet door 22 hinged to its surface. The fire distribution cabinet body 11 has two through slots 23 symmetrically opened inside. Both through slots 23 are located inside the T-shaped slot 12. The inner walls of both through slots 23 have rectangular slots 24. Both rectangular slots 24 (the surface of the rectangular slots 24 is sprayed with a magnetic coating) are magnetically connected to rectangular frames 25 (the rectangular frames 25 are made of metal and can be attracted with the magnetic coating). Both rectangular frames 25 have filters 26 inside, and both filters 26 are located at the through slots 23.

[0034] By setting a through groove 23 in the fire distribution cabinet body 11 and opening a rectangular groove 24 in its inner wall, and configuring a combination structure of magnetic rectangular frame 25 and filter screen 26, it can effectively prevent dust from entering the cabinet and interfering with the operation of components, maintain normal heat dissipation function, facilitate maintenance work, and when the fire extinguishing sprayer 15 is activated, the radial force of its high-pressure spray medium can cause the filter screen 26 to actively and automatically detach from the through groove 23, ensuring that the fire extinguishing medium covers the cabinet space without obstruction, thereby eliminating the technical hidden dangers that hinder the fire extinguishing effect.

[0035] Working principle:

[0036] First, during use, when the fire distribution cabinet body 11 is on fire, the smoke sensor 21 will detect the fire inside the fire distribution cabinet body 11 and send a signal to the multi-functional module unit 19, causing the multi-functional module unit 19 to control the output shaft of the electric push rod 17 to retract, and then drive the U-shaped rod 16 to move through the connecting rod 18, thereby driving the slider 13 and the rectangular frame 14 to slide upward along the T-shaped groove 12. When the electric push rod 17 retracts to the limit, the slider 13 will be located at the top above the T-shaped groove 12.

[0037] In the second step, when the slider 13 is located at the top of the T-shaped groove 12, the rectangular frame 14 will block the through groove 23, and then the fire extinguishing sprayer 15 will be activated, spraying the fire extinguishing medium under high pressure and spraying it towards the filter screen 26. At this time, the rectangular frame 25 and the filter screen 26 will be separated from the through groove 23 and the rectangular groove 24 due to their radial force. At the same time, the fire extinguishing sprayer 15 will thoroughly clean the inside of the fire distribution cabinet body 11.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
