DETAILED DESCRIPTION

[0023] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings.

[0024] Embodiment 1

[0025] The launching fire blanket of the embodiment, as shown in Figure 1 , 2 , 3, comprises a fixed plate 1, an electromagnetic launcher 2 and a fire blanket 6; the fixed plate 1 is installed above a key fire-fighting area; the fixed end of the electromagnetic launcher 2 is fixedly connected with the fixed plate 1, and the free end thereof is a firing port 28, which faces the key fire-fighting area; the edge of the fire blanket 6 is connected with a counterweight bullet 61, the counterweight bullet 61 can be connected with the fire blanket 6 through a pull rope, and the counterweight bullet 61 is embedded in the firing port 28.

[0026] The launching fire blanket of the embodiment, in specific use, when a fire occurs in the key fire-fighting area, the electromagnetic launcher 2 directly covers the fire blanket 6 on the fire source, thereby completing the extinguishing operation.

[0027] Embodiment 2

[0028] The launching fire blanket of the embodiment has the same basic structure as that of embodiment 1, and the difference or improvement lies in that the electromagnetic launcher 2 is a plurality of symmetrically or uniformly installed ones, as shown in Figure 1 , 2 , 3, four of which are installed at the four corners of the square fixed plate 1; a plurality of counterweight bullets 61 matched with the electromagnetic launchers 2 are symmetrically or uniformly connected at the edge of the fire blanket 6; when the electromagnetic launchers 2 are four, the counterweight bullets 61 are also four, which are connected at the four corner edges of the square fire blanket 6, so as to achieve the purpose of covering the set key fire-fighting area as much as possible after the four corner edges of the fire blanket 64 are opened.

[0029] In a non-fire-fighting state, as shown in Figure 1 ,​​2 As shown in Figure 3, the fire blanket 6 is stored in the storage box 3 to maintain its good working condition. The storage box 3 is connected to the fixing plate 1 by a magnetic cable 4. The magnetic force is slightly greater than the weight of the storage box 3 and the fire blanket 6 to avoid insufficient impact force from the counterweight projectile 61 launched by the electromagnetic launcher 2, which would affect the opening effect of the fire blanket 6. The launch port 28 is tilted outward, which can launch the edge of the fire blanket 6 outward at an angle, improving the opening effect of the fire blanket 6 and expanding the fire-fighting area.

[0030] Example 3

[0031] The basic structure of the fire blanket in this embodiment is the same as that in Embodiment 2, with the following differences or improvements: Figure 4 , 5 As shown, the rear of the electromagnetic launcher 2 is a stock 21, and the end of the stock 21 is connected to a mounting ball 211. The mounting ball 211 is embedded in the secondary fixing plate 5. The secondary fixing plate 5 is detachably connected to the corner of the fixing plate 1. The mounting ball 211 forms a spherical hinge connection. When fixed, the screw is tightened to press down the spherical body of the mounting ball 211. After the screw is loosened, the position can be adjusted. According to different usage scenarios, the firing angle of the counterweight bullet 61 can be adjusted by rotating the mounting ball 211.

[0032] like Figure 4 , 5 As shown, the electromagnetic launcher 2 includes a stock 21, a locking blade 22, a locking blade spring 23, an electromagnetic coil 24, a firing pin 25, a firing pin spring 26, and a barrel 27. The electromagnetic coil 24 is connected to the bottom of the stock 21 and communicates with the barrel 27 through the mounting hole of the locking blade 22. The firing pin 25 and the firing pin spring 26 are installed horizontally inside the barrel 27. The end of the firing pin 25 is a slot 251, and the firing pin spring 26 surrounds the front part of the firing pin 25. The locking blade 22 extends upward, and when the top of the locking blade 22 is locked in the slot 251, the firing pin spring 26 presses the firing pin 25 tightly inside the barrel 27. The locking blade spring 23 is installed inside the electromagnetic coil 24, and the top of the locking blade spring 23 is connected to the bottom of the locking blade 22. When the electromagnetic coil 24 is de-energized and energized, the locking blade 22 is in an extended and retracted state, respectively, so as to achieve the purpose of launching the counterweight bullet 61 through induction.

[0033] The fire blanket in this embodiment is designed for use in new energy vehicles. It is an electromagnetic emission type automatic fire blanket device for automobiles. Referring to existing automated fire sprinkler systems, this device can also be integrated into a fire smoke detection system for fire prevention and fighting in underground parking garages.

[0034] When the device works in the coverage area, the fire smoke sensing system detects the fire and automatically reports the fire signal and triggers the automatic fire blanket to work: the electromagnetic coil 24 is powered, the lock knife 22 is retracted downward with the lock knife spring 23, the striker 25 is released, the striker spring 26 is released, and the striker 25 is quickly ejected to release the counterweight bullet 61 from the muzzle 27 of the gun barrel 27. The counterweight bullet 61 carries the fire blanket 6 to the set direction and covers the set working area to complete the extinguishing operation. The fire can be automatically, quickly and effectively extinguished under unattended conditions, preventing the fire from spreading and protecting people's property and personal safety.

[0035] The above describes the utility model and its embodiments in a schematic manner, which is not restrictive, and the drawings only show one of the embodiments of the utility model, and the actual structure and manufacturing steps are not limited thereto. Therefore, if a person skilled in the art is inspired thereby, similar structural modes and embodiments can be designed without departing from the creative purpose of the utility model, which should all belong to the protection scope of the utility model.
