Description

Technical Field

[0001] This utility model relates to the field of fireproof rolling shutter door technology, and in particular to an intelligent emergency fireproof rolling shutter door device for underground coal mines. Background Technology

[0002] Intelligent emergency fireproof rolling shutters for underground coal mines are safety facilities specifically designed for the underground environment of coal mines. Their purpose is to provide rapid isolation and fire prevention in the event of a fire or emergency, protecting miners' lives and reducing the risk of fire spread. These devices typically possess intelligent, automated, and fireproof functions, enabling rapid response in emergencies such as fires, thereby effectively reducing accidents and ensuring the safety of mine workers.

[0003] Traditional intelligent emergency fireproof rolling shutters in coal mines mostly lack sprinkler systems. While these fireproof rolling shutters possess some high-temperature resistance and fireproofing capabilities, capable of partially preventing the spread of fire, their surfaces may deform, melt, or crack due to the sustained high temperatures once flames come into contact with them during a fire. Especially in intense fires, traditional fireproof doors may fail to effectively block the flames, leading to damage to the door itself, and even allowing flames to penetrate the shutter and spread to other areas, thus delaying emergency response and increasing the risk of fire spread. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an intelligent emergency fireproof rolling shutter door device for underground coal mines, aiming to improve the problem that most intelligent emergency fireproof rolling shutter door devices for underground coal mines do not have sprinkler fire extinguishing mechanisms, resulting in damage to the rolling shutter door body and the risk of fire spread.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent emergency fireproof rolling shutter door device for underground coal mines, comprising a roller, a drive device inside the roller, two door frames fixedly connected to the bottom of the roller, a door curtain slidably connected between the two door frames, a spraying mechanism at the top of the roller, the spraying mechanism being used to spray water when a fire occurs underground to prevent the fire from affecting the normal operation of the device, and a sealing mechanism at the bottom of the door curtain, the sealing mechanism being used to enhance the overall sealing performance of the device;

[0006] The spraying mechanism includes a water tank, the bottom of which is fixedly connected to the top of the roller, a mounting bracket is fixedly connected to the outside of the water tank, and a drive motor is fixedly connected to the top of the mounting bracket.

[0007] As a further description of the above technical solution:

[0008] The output end of the drive motor is fixedly connected to a rotating shaft, the bottom of the rotating shaft is fixedly connected to a crank, the bottom of the crank is fixedly connected to a connecting shaft, the bottom of the connecting shaft is fixedly connected to a U-shaped frame, a pipe sleeve is rotatably connected inside the U-shaped frame, a water supply pipe is fixedly connected inside the pipe sleeve, and several spray pipes are fixedly connected to the bottom of the water supply pipe.

[0009] As a further description of the above technical solution:

[0010] The drive motor extends through the top of the water tank.

[0011] As a further description of the above technical solution:

[0012] One end of the water supply pipe is rotatably connected to the inside of the mounting frame, and the other end of the water supply pipe is rotatably connected to a connecting pipe.

[0013] As a further description of the above technical solution:

[0014] The end of the connecting pipe away from the water supply pipe is fixedly connected to the outside of the water tank.

[0022] 1. In this utility model, when a fire occurs outside the roller shutter door, the door curtain is lowered by the drive device, and the drive motor is started. The crank is driven by the shaft, which causes the U-shaped frame to swing back and forth. Water is drawn from the water tank through the water supply pipe and sprayed through the spray pipe, preventing the flames from spreading to the roller shutter door. This achieves the function of timely fire extinguishing by spraying when a fire occurs, effectively preventing the fire from spreading to the vicinity of the roller shutter door, extending the service life of the roller shutter door, and reducing the risk of fire spread.

[0023] 2.

[0031] Reference Figures 1-3This utility model provides an embodiment of an intelligent emergency fireproof rolling shutter door device for underground coal mines, including a roller 1, which controls the door curtain 4. The roller 1 is equipped with a drive device 2, which provides power to drive the roller 1. Two door frames 3 are fixedly connected to the bottom of the roller 1, which fix the door curtain 4. The door curtain 4 is slidably connected between the two door frames 3. A spray mechanism is provided at the top of the roller 1, which sprays water to prevent the fire from affecting the normal operation of the device when a fire occurs underground. A sealing mechanism is provided at the bottom of the door curtain 4 to enhance the overall sealing performance of the device.

[0032] The spraying mechanism includes a water tank 5, which stores water. The bottom of the water tank 5 is fixedly connected to the top of the roller 1. A mounting bracket 6 is fixedly connected to the outside of the water tank 5, which secures the internal structure. A drive motor 7 is fixedly connected to the top of the mounting bracket 6, which provides power to drive the rotating shaft 8. The output end of the drive motor 7 is fixedly connected to the rotating shaft 8, which connects to a crank 9. The bottom of the rotating shaft 8 is fixedly connected to the crank 9, which mounts a connecting shaft 10. The bottom of the crank 9 is fixedly connected to the connecting shaft 10, which connects to a U-shaped frame 11. The bottom of the connecting shaft 10 is fixedly connected to the U-shaped frame 11, which connects to a pipe sleeve 12. The pipe sleeve 12 is rotatably connected inside the U-shaped frame 11, which connects to a water supply pipe 13. The inside of the sleeve 12 is fixedly connected to a water supply pipe 13, which serves to connect to the sprinkler pipe 14. Several sprinkler pipes 14 are fixedly connected to the bottom of the water supply pipe 13, which serve to spray water for fire extinguishing. The drive motor 7 passes through the top of the water tank 5. One end of the water supply pipe 13 is rotatably connected to the inside of the mounting bracket 6, and the other end of the water supply pipe 13 is rotatably connected to a connecting pipe 20, which serves to supply water. The end of the connecting pipe 20 away from the water supply pipe 13 is fixedly connected to the outside of the water tank 5.

[0033] When a fire occurs outside the roller shutter door, the drive motor 7 drives the crank 9 to make the water supply pipe 13 swing from inside the water tank 5 through the sprinkler pipe 14 to spray water to extinguish the fire.

[0034] Reference Figures 1-2 and Figure 4The sealing mechanism includes a mounting shell 15, which serves to fix the internal structure. The mounting shell 15 is fixedly connected to the bottom of the curtain 4. Several springs 16 are fixedly connected inside the mounting shell 15. The springs 16 provide elastic force to push the limiting plate 17. The limiting plate 17 is fixedly connected to the bottom of the springs 16, which prevents the springs 16 from falling off. A compression plate 18 is fixedly connected to the bottom of the limiting plate 17, which connects to the sealing gasket 19. The sealing gasket 19 is fixedly connected to the bottom of the compression plate 18, which enhances the sealing performance of the bottom of the curtain 4. The limiting plate 17 is slidably connected inside the mounting shell 15, and the compression plate 18 penetrates through the bottom of the mounting shell 15.

[0035] When the curtain 4 is lowered to the bottom, the spring 16 inside the mounting shell 15 provides elasticity to make the sealing gasket 19 stick tightly to the ground.

[0036] Working principle: When a fire occurs outside the roller shutter door, the door curtain 4 is lowered by the drive device 2, and the drive motor 7 is started. The crank 9 is driven by the shaft 8, which causes the U-shaped frame 11 to swing back and forth with the sleeve 12. Water is drawn from the water tank 5 through the water supply pipe 13 and sprayed through the spray pipe 14 to prevent the flames from burning onto the roller shutter door.

[0037] When the curtain 4 is lowered to its lowest position, the spring 16 inside the mounting housing 15 provides elastic force to push the compression plate 18 through the limiting plate 17, so that the sealing gasket 19 is pressed tightly against the ground, which enhances the sealing of the bottom of the roller shutter door and prevents smoke and dust from entering the door.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
