Description

Technical Field

[0001] This invention relates to the field of emergency lighting technology, and more specifically, to a lighting device for fire emergency use. Background Technology

[0002] Fire emergency evacuation lighting is one of the most common lighting tools used in fire emergencies. In emergencies such as earthquakes, fires, or sudden power outages caused by electrical faults, when all light sources have stopped working, fire emergency evacuation lighting can provide illumination for personnel evacuation and firefighting operations.

[0003] Because fire emergency evacuation lighting devices are installed high on the wall, when a fire occurs, smoke rises and fills the entire escape route. The large amount of smoke not only obstructs vision but also makes it difficult for people to breathe, causing them to suffocate and faint. In addition, the lights are on the wall for a long time, and a lot of dust will adhere to the surface of the lampshade in front of the lights, affecting the lighting effect. Summary of the Invention

[0004] In order to overcome the disadvantages of smoke rising and filling the entire escape route during a fire, which not only obstructs vision but also makes it difficult for people to breathe, and in severe cases, can lead to suffocation and death, this invention provides a fire emergency lighting device.

Through the above arrangement, the ring is attracted, thereby improving stability.

[0006] To wet the filter cotton roll, it is more preferable that the wetting mechanism includes a vertical plate; the vertical plate is fixedly connected to the inside of the box; a herringbone plate is fixedly connected to the front side of the vertical plate, and the herringbone plate is provided with an irregular groove; the lower side of the herringbone plate is fixedly connected to the winding frame; the end of the filter cotton roll passes through the herringbone plate and falls on the irregular groove; a water bag is provided inside the box located on the upper side of the herringbone plate; two round rods are fixedly connected inside the box located behind the vertical plate; each round rod is fitted with a spring; a U-shaped plate located on the upper side of the two springs is slidably connected to the two round rods; two vertical grooves are opened on the vertical plate, and the U-shaped plate is slidably disposed in the two vertical grooves; a horizontal bar is fixedly connected to the U-shaped plate located in front of the vertical plate; a limiting groove is opened on the left side of the box, and the horizontal bar is slidably disposed in the limiting groove; the left part of the horizontal bar is fixedly connected to a rope; a protruding plate is fixedly connected to the lower part of the horizontal bar; a rotating plate is rotatably connected to the herringbone plate through a torsion spring; the front side of the rotating plate is provided with a serrated part.

[0007] More preferably, it also includes a sealing plate; the front of the herringbone plate is connected to the sealing plate by a damped sliding connection.

[0008] More preferably, the sealing plate is provided with a ball head.

[0009] More preferably, it also includes fixing blocks; two fixing blocks are fixed to the upper surface of the box, and each fixing block is located below a light; two diagonal rods located on both sides of the light are fixed to each fixing block; an elastic rope is provided on the two diagonal rods of each fixing block, and both elastic ropes are located above the light.

[0010] More preferably, each elastic cord has a layer of nap on its surface.

[0011] The above settings improve the effectiveness of dust removal.

[0012] More preferably, it also includes a flashlight; a groove is provided at the front of the box; the flashlight is inserted into the groove; a straight sliding groove is provided on the front side and the top surface of the box; a protective plate is slidably connected in the two straight sliding grooves.

[0013] More preferably, the front side of the protective plate is provided with several semi-circular strips.

Then, the box body detaches from the mounting shell and continues to fall downwards, hanging in the air at a height that is easily accessible to escapees. This allows escapees to easily tear off the filter cotton roll to cover their mouth and nose, preventing the body from inhaling smoke and dust and causing breathing difficulties or suffocation, and facilitating the rapid evacuation of escapees from the fire area.

[0017] The fire emergency lighting device designed in this invention guides the air blown out by the fan through the horn cover, increases the airflow speed, and allows the air to flow continuously along the back of the lighting lamp, blowing away the smoke within the lighting range and improving the lighting effect.

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Example 1: A fire emergency lighting device, such as Figures 1-6 As shown, it includes a mounting housing 1 and a lighting lamp 2; two lighting lamps 2 are fixedly connected to the upper front part of the mounting housing 1; It also includes a housing 3, ropes 4, a winding frame 5, filter cotton rolls 6, a wetting mechanism, ropes 7, rings 8, and an electromagnet 9; the housing 3 is connected to the lower part of the mounting shell 1 by a damping sliding connection; two ropes 4 are fixed to the upper surface of the housing 3, and the two ropes 4 are fixed to the mounting shell 1; the winding frame 5 is connected inside the housing 3; the filter cotton rolls 6 are wound on the rotating shaft of the winding frame 5, and the ends of the filter cotton rolls 6 are exposed outside the housing 3; several equally spaced saddle stitches are provided on the filter cotton rolls 6; the wetting mechanism is connected inside the housing 3; ropes 7 are connected to the wetting mechanism; rings 8 are fixed to the ends of the ropes 7; an electromagnet 9 is fixed to the upper surface of the housing 3, and the rings 8 are made of magnetic material, and the electromagnet 9 is magnetically connected to the rings 8.

[0022] The wetting mechanism includes a vertical plate 101, a herringbone plate 102, a water bag 103, round rods 104, a spring 105, a U-shaped plate 106, a horizontal bar 107, a convex plate 108, and a rotating plate 109. A vertical plate 101 is fixedly connected to the left side of the inner part of the housing 3, creating a separate space within the housing 3. A herringbone plate 102 is fixedly connected to the front side of the vertical plate 101, and the herringbone plate 102 has a shaped groove 10201 for guiding and accommodating the filter cotton roll 6, further dividing the space within the vertical plate 101 into upper and lower layers. The lower side of the herringbone plate 102 is fixedly connected to the winding frame 5. The end of the filter cotton roll 6 passes through the herringbone plate 102 and falls onto the shaped groove 10201. A water bag 103 is installed inside the housing 3, located above the herringbone plate 102. Two round rods 104 are fixedly connected inside the housing 3, and the two round rods 105... Rod 104 is located behind vertical plate 101; each round rod 104 is fitted with a spring 105; a U-shaped plate 106 is slidably connected to the two round rods 104, and the U-shaped plate 106 is located above the two springs 105; two vertical grooves 10101 are opened on vertical plate 101, and the U-shaped plate 106 is slidably disposed in the two vertical grooves 10101; a crossbar 107 is fixedly connected to the U-shaped plate 106, and the crossbar 107 is located in front of vertical plate 101; a limiting groove 3001 is opened on the left side of box 3, and the crossbar 107 is slidably disposed in the limiting groove 3001; the left part of the crossbar 107 is fixedly connected to rope 7; a protruding plate 108 is fixedly connected to the lower part of the crossbar 107; a rotating plate 109 is rotatably connected to the herringbone plate 102 through a torsion spring; a serrated part 10901 is provided on the front side of the rotating plate 109.

[0023] It also includes a sealing plate 110; the front of the herringbone plate 102 is connected to the sealing plate 110 with a damping sliding connection. The sealing plate 110 blocks the irregular groove 10201 to prevent dust from entering the herringbone plate 102 and adhering to the filter cotton roll 6, thus contaminating the filter cotton roll 6.

[0024] The sealing plate 110 is equipped with a ball head 11001 to facilitate escapers to grab the sealing plate 110 and move it downwards.

[0025] It also includes a fixing block 201, a diagonal rod 202, and an elastic rope 203; two fixing blocks 201 are fixedly attached to the upper surface of the housing 3, and each fixing block 201 is located below a lighting lamp 2; two diagonal rods 202 are fixedly attached to each fixing block 201, and the two diagonal rods 202 are located on both sides of the lighting lamp 2; an elastic rope 203 is provided on the two diagonal rods 202 of each fixing block 201, and both elastic ropes 203 are located above the lighting lamp 2.

[0026] Furthermore, each elastic cord 203 has a layer of nap on its surface.

[0027] The further advantage of adopting the above method is that it improves the efficiency of cleaning dust on the lighting lamp 2.

[0028] It also includes a flashlight 204 and a protective plate 205; a groove 3002 is provided at the front of the box 3; the flashlight 204 is inserted into the groove 3002; a straight slide groove 3003 is provided on the front side and the top surface of the box 3; the protective plate 205 is slidably connected in the two straight slide grooves 3003.

[0029] The front side of the protective plate 205 is provided with several semi-circular strips to prevent slippage when escapers push the protective plate 205.

[0030] Furthermore, a fluorescent silicone layer is provided on the surface of the ring 8.

[0031] The further advantages of using the above are: the fluorescent silicone layer prevents people from being scratched when pulling the ring 8, and the fluorescent material makes the ring 8 easier to spot in dim environments.

[0032] The working steps of this embodiment are as follows: The following directions are Figure 1 Using the reference angle, the direction where the mounting shell 1 is located is to the left. The rotations described below refer to the viewing angles from front to back, from top to bottom, and from right to left. When in use, this fire emergency lighting device is installed high on the wall of the escape route. An external power supply is connected to the mounting shell 1. A small storage battery is installed inside the mounting shell 1. The small storage battery supplies power to the lighting lamp 2 and the flashlight 204 when the external power supply is disconnected. In the event of a fire, the external power supply is automatically disconnected, and the two lights 2 automatically turn on to illuminate the escape route. Simultaneously, after the electromagnet 9 is de-energized, it no longer attracts the ring 8. Under the influence of gravity, the rope 7 and ring 8 hang down below the housing 3. This allows escapees to easily grab the rope 7 or ring 8 when passing the emergency lighting device. Once the escapee grabs the rope 7, it pulls the rope 7, U-shaped plate 106, crossbar 107, and protruding plate 108 downwards together, causing the crossbar 107 to slide within the limiting groove 3001, and the U-shaped plate 106 to slide within the two vertical sliding grooves 101. As the crossbar 107 slides within 01, the two springs 105 are forced to compress. During the movement, the crossbar 107 will move downward along the surface of the water bag 103 until the crossbar 107 reaches the bottom of the limiting groove 3001. The protruding plate 108 contacts the rotating plate 109, forcing the rotating plate 109 to flip upward on the herringbone plate 102. At the same time, while opening an opening on the herringbone plate 102, the serrated part 10901 of the rotating plate 109 punctures the water bag 103 upward, causing the water in the water bag 103 to flow out quickly and enter the area below the herringbone plate 102 through the opening, quickly wetting the filter cotton roll 6.

[0033] At this point, the escapee continues to move downwards along with the box 3, the winding frame 5, the filter cotton roll 6, the wetting mechanism, and the electromagnet 9 via rope 7. As the box 3 moves along the mounting shell 1, it carries the fixing block 201, the diagonal bar 202, and the elastic rope 203 downwards. The fibers on the elastic rope 203 clean the dust adhering to the surface of the front lampshade of the lighting lamp 2, preventing accumulated dust from affecting the brightness of the lighting lamp 2, until the box 3 detaches from the mounting shell 1 and continues to fall to a height easily accessible to the escapee. The box 3 and its connected components are then held in place by two ropes 4, suspending it in the air. Figure 6 As shown, the person escaping then holds the ball head 11001 and pushes the sealing plate 110 downwards to open the irregular groove 10201. They then grab the end of the filter cotton roll 6 and pull it out. When the seam on the filter cotton roll 6 moves out of the herringbone plate 102, they tear off the pulled-out part of the filter cotton roll 6 to cover their mouth and nose, preventing the person from inhaling smoke and dust and causing breathing difficulties or suffocation. This allows the person escaping to quickly move away from the fire area.

[0034] When escapees need to pass through a dark passage but lack lighting and cannot quickly escape from a fire, the escapees can push the protective plate 205 through the fire emergency lighting device to slide within the two linear grooves 3003, exposing the flashlight 204 in the groove 3002. The flashlight 204 can then be taken out of the groove 3002 to illuminate the passage, facilitating a rapid escape for the escapees.

[0035] Example 2: Based on Example 1, such as Figure 5As shown, it also includes a fan 301, a mounting bracket 302, and a speaker cover 303; two fans 301 are fixedly connected to the upper rear part of the mounting housing 1, and the fans 301 are located behind the lighting lamp 2; two mounting brackets 302 are fixedly connected to the upper middle part of the mounting housing 1, and the mounting brackets 302 are located between the lighting lamp 2 and the fans 301; a speaker cover 303 is fixedly connected to each mounting bracket 302, and the lighting lamp 2 is located inside the front side of the speaker cover 303; the rear side of the speaker cover 303 communicates with the fan 301.

[0036] The working principle of this embodiment is as follows: Because the light from the fire emergency evacuation lighting device cannot penetrate the smoke-illuminating evacuation passage, the lighting effect of the fire emergency evacuation lighting device is limited, resulting in difficulties in personnel evacuation. Therefore, after the lighting lamp 2 is turned on, the two fans 301 are controlled to turn on and continuously blow air towards the back of the two lighting lamps 2 to blow away the smoke around the lighting lamps 2. However, due to the high concentration of smoke and the wide coverage of the smoke, the fans 301 alone cannot blow away the smoke within the illumination range of the lighting lamps 2. Therefore, the horn cover 303 is used to guide the air blown out by the fans 301, increase the airflow speed, and make it flow continuously along the back of the lighting lamps 2 to blow away the smoke within the illumination range of the lighting lamps 2, thereby improving the lighting effect of the lighting lamps 2.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
