[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figures 2 - 4 , an embodiment provided by the present utility model: a multi-functional LED emergency lighting device for fire protection, including a controller 1. A lamp cover 2 is fixedly connected to the top of the controller 1. An explosion-proof lamp 3 is arranged inside the lamp cover 2. A housing 4 is fixedly connected to the outer wall of the explosion-proof lamp 3. A heat sink 6 is fixedly connected to the outer wall of the housing 4. One side of the heat sink 6 is fixedly connected to the inner wall of the lamp cover 2. A guide plate 5 is fixedly connected to one end of the housing 4. A fan 7 is fixedly connected inside the lamp cover 2. An installation groove 22 is formed inside the lamp cover 2. A dust-proof net 8 is rotatably connected inside the lamp cover 2. A fixing block 9 is fixedly connected to the outer wall of the dust-proof net 8. The outer wall of the fixing block 9 slides inside the installation groove 22. A reset assembly is arranged inside the dust-proof net 8. The reset assembly is used to reset and lock the fixing block 9 inside the installation groove 22. The reset assembly includes a first spring 10. The outer wall of the first spring 10 is arranged inside the dust-proof net 8. One end of the first spring 10 is fixedly connected to the inside of the dust-proof net 8. The other end of the first spring 10 is fixedly connected to one end of the fan 7.

[0034] Specifically, when the explosion-proof lamp 3 works, the heat generated by the explosion-proof lamp 3 is effectively conducted through the heat sinks 6 arranged uniformly on the outer wall of the housing 4, thereby increasing the contact area between the heat sinks 6 and the air. Subsequently, the fan 7 inhales the external air between the lamp cover 2 and the housing 4 through the filtration of the dust-proof net 8, so that the air flows through the heat sinks 6, thereby taking away the heat on the heat sinks 6. The dust-proof net 8 can not only filter the air, but also prevent the smoke and dust in the fire environment from adhering to the heat sinks 6, avoiding the problem of heat dissipation failure caused by the accumulation of smoke and dust. The dust-proof net 8 is firmly locked by sliding the fixing block 9 into the installation groove 22 on the lamp cover 2 and is supported by the tension of the first spring 10, so that the fixing block 9 is stably fitted inside the installation groove 22, ensuring that the dust-proof net 8 is not easily dropped during use. This design not only optimizes the heat dissipation effect of the explosion-proof lamp 3, but also improves its reliability and service life in harsh environments.

[0035] Referring to Figure 1 、 Figure 5 and Figure 6, on the outer wall of the controller 1, there are a second housing 11 and a third housing 12. Inside both the second housing 11 and the third housing 12, there is a fixed heat insulation layer 13. On one side of the third housing 12, there is a fixed sealing ring 14. One side of the sealing ring 14 is fixedly connected to one side of the second housing 11. On the outer wall of the second housing 11, there is a fixed connection seat 16. On the outer wall of the third housing 12, there is a high-temperature resistant strap 15. Inside the high-temperature resistant strap 15, there is a card slot 17. The outer wall of the high-temperature resistant strap 15 is slidably connected inside the connection seat 16. Inside the connection seat 16, there is a slidable limit plate 18. At the bottom of the limit plate 18, there is a fixed card block 19. The outer wall of the card block 19 is fitted inside the card slot 17. Inside the connection seat 16, there is a telescopic rod 20. A second spring 21 is sleeved on the outer wall of the telescopic rod 20. One end of the telescopic rod 20 and the second spring 21 are both fixedly connected inside the connection seat 16. The other end of the telescopic rod 20 and the second spring 21 are both fixedly connected to the top of the limit plate 18;

[0036] Specifically, through the close cooperation of the second housing 11 and the third housing 12, the controller 1 is effectively protected. Both the second housing 11 and the third housing 12 are made of strong steel materials, providing reliable support and a certain explosion-proof function. To further enhance safety, there is a heat insulation layer 13 between these two layers of housings and the controller 1. The heat insulation layer 13 is made of high-purity alumina fiber material, having excellent high-temperature resistance and being able to effectively prevent fire. Between the second housing 11 and the third housing 12, there is also a tight seal through the sealing ring 14 to prevent any external substances from entering. Then, the high-temperature resistant strap 15 on the third housing 12 is inserted inside the connection seat 16 on the second housing 11 to complete the fixed assembly. Inside the connection seat 16, the card block 19 is fitted inside the card slot 17 on the high-temperature resistant strap 15 to achieve a firm lock. The limit of the card block 19 is provided by the limit plate 18, which plays a role in restricting the position inside the connection seat 16 and is supported by the tension of the second spring 21, making the card block 19 stably fitted inside the card slot 17 to ensure the firmness and safety of the overall structure.

[0037] Working principle: When using this fire-fighting LED multi-functional emergency lighting device, first, the controller 1 is protected by the cooperation of the second housing 11 and the third housing 12. Both the second housing 11 and the third housing 12 are supported by steel housings, which have a certain explosion-proof effect. Fire prevention is carried out between the second housing 11 and the third housing 12 and the controller 1 through the heat insulation layer 13. The heat insulation layer 13 is made of high-purity alumina fiber material and has excellent high-temperature resistance. Subsequently, the second housing 11 and the third housing 12 are sealed through the sealing ring 14. Then, the second housing 11 and the third housing 12 are fixedly assembled by inserting the high-temperature resistant strap 15 on the third housing 12 into the connecting seat 16 on the second housing 11. The block 19 in the connecting seat 16 is fitted into the slot 17 on the high-temperature resistant strap 15 for locking. The block 19 is limited inside the connecting seat 16 through the limiting plate 18, and the block 19 is fitted into the slot 17 and firmly locked by the tension support of the second spring 21. Subsequently, when the explosion-proof lamp 3 works, the heat generated by the explosion-proof lamp 3 is conducted through the heat dissipation fins 6 evenly arranged on the outer wall of the first housing 4 to increase the contact area with the air. Then, the fan 7 inhales the external air between the lamp cover 2 and the first housing 4 through the filtration of the dust-proof net 8, so that the air takes away the heat on the heat dissipation fins 6 after passing through the heat dissipation fins 6. The dust-proof net 8 can prevent the problem that the soot in the fire environment adheres to the heat dissipation fins 6 and causes heat dissipation failure. The dust-proof net 8 is slid into the installation slot 22 on the lamp cover 2 through the fixing block 9 and is stuck, and is supported by the tension of the first spring 10, so that the fixing block 9 is fitted into the installation slot 22 and the dust-proof net 8 is not easily dropped.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
