[0024] like Figures 1 to 6As shown, the present invention provides a drop-type self-deployable fire extinguishing device, which includes a storage mechanism 10 for suspension, and a fire blanket 11 and an ejection mechanism 12 are arranged inside the storage mechanism 10, wherein the outer circumference of the fire blanket 11 is wound toward the center of the fire blanket 11, and the fire blanket 11 is arranged on the ejection mechanism 12 after being wound, so that the fire blanket 11 can be ejected from the storage device 10 by the ejection mechanism 12 when in use. The ejection mechanism 12 is connected to the storage mechanism 10, and the storage mechanism 10 is provided with an opening 13 for ejecting the fire blanket 11. The storage mechanism 10 is provided with a transmission device 16 connected to the actuator 141 of the fire actuator 14, and the transmission device 16 is used to enable the ejection mechanism 12 to eject the fire blanket 11. The fire actuator of the present invention includes a temperature sensing device 18 for detecting temperature, and the fire actuator 14 is an existing structure, which is based on the ability to realize its function, and an applicable selection can be made when in use. Specifically, the fire actuator 14 includes a rotatable actuator 142 and an actuator rod 141 connected to the actuator 142. The temperature sensing device 18 may be a temperature probe, and the temperature sensing device 18 is disposed at a position conducive to receiving heat, such as above or below the storage mechanism 10.

[0025] The present invention is suitable for environments where a fire actuator 14 is installed, such as a garage. When in use, the storage mechanism 10 can be connected to the ceiling through the fixing frame 15, and the temperature sensing device 8 is used to detect the ambient temperature. When the fusible piece on the temperature sensing device 18 reaches the set temperature, the actuator rod 141 of the fire actuator 14 is actuated, driving the transmission device 16 to move so that the ejection mechanism 12 ejects the fire blanket 11, so that the fire blanket 11 is opened and released to cover the fire point, preventing the fire from spreading further.

[0026] One embodiment of the present invention is Figures 1 to 3As shown: the storage mechanism 10 is a hollow box 101, an opening 13 is provided at the bottom of the box 101, and a door panel 102 that can be opened and closed is provided at the opening 13. The door panel 102 is movably connected to the box 101. Specifically, the door panel 102 and the box 101 can be connected by a torsion spring 19. In a natural state, the door panel 102 opens outward. Grooves 104 are provided on the side panels 103 of the box 101. A positioning rod 105 is provided below the door panel 102 to support the door panel 102. The positioning rod 105 penetrates the groove 104 and is movably arranged in the groove 104. When in use, the positioning rod 105 is peeled off from the groove 104, so that the door panel 102 can be opened to release the ejection mechanism 12 and the fire blanket 11 in the storage mechanism 10. Further, the transmission device 16 includes a first connecting rod 161 and a second connecting rod 162, the first connecting rod 161 is connected to the actuator rod 141 of the fire actuator 14, and the two ends of the first connecting rod 161 are respectively provided with and movably connected with the second connecting rod 162, and the second connecting rod 162 is connected to the rotating shaft 163, and the rotating shaft 163 is respectively provided on both sides of the side plate 103. The rotating shaft 163 is connected to a special-shaped block 164, which is provided on one side of the positioning rod body 105 to push the positioning rod body 105 away from the groove 104. The special-shaped block 164 of the present invention can be a cam or other structure, which is based on the ability to achieve its function. When in use, the actuating rod 141 of the fire actuator 14 performs an actuating action to deflect, driving the first connecting rod 161 connected thereto to move, the first connecting rod 161 drives the second connecting rod 162 to move to rotate the rotating shaft 163, the rotating shaft 163 drives the special-shaped block 164 to rotate, so that one end of the special-shaped block 164 pushes the positioning rod body 105 out of the groove 104, the positioning rod body 105 is separated from the groove 104 to open the door panel 102, and release the fire blanket 11. Further, a positioning block 165 is sleeved on the rotating shaft 163, the rotating shaft 163 can rotate on the positioning block 165, and the positioning block 165 is arranged on the side plate 103, which can prevent the rotating shaft 163 from being misplaced when the second connecting rod 162 drives the rotating shaft 163 to rotate, thereby causing the special-shaped block 164 to fail to touch the positioning rod body 105. Furthermore, the ejection mechanism 12 includes a drop plate 121 and a connecting device 20 connecting the drop plate 121 to the storage mechanism 10, and the fire blanket 11 is wound on the ejection mechanism 12 and the connecting device 20. The connecting device 20 can be a structure such as a cloth or a rope plate that can be stacked and installed in the storage mechanism 10, and the connecting device 20 can be connected to the four sides of the drop plate 121 at multiple points to achieve its function. When the door panel 102 is opened, the drop plate 121 descends, gravity tightens the connecting device 20, and the fire blanket 11 is ejected and unfolded.

[0027] The operating principle of the first embodiment of the present invention is: the temperature is detected by the temperature sensing device 18. When the temperature sensing device 18 reaches the set temperature, the fire actuator 14 performs an execution action, and the driving transmission device 16 peels the positioning rod body 105 off the groove 104, and opens the door panel 102, releasing the fire blanket 11 and the drop plate 121. The connection device 20 tightened by gravity pops out the fire blanket 11 to cover the fire point below it to prevent it from spreading.

[0028] The second embodiment of the present invention is Figures 4 to 6 As shown: the storage mechanism 10 includes a top cover 106 and a bottom plate 107 disposed below the top cover 106. Further, the top cover 106 is provided with a through hole 100, and a hollow sleeve 108 penetrates the top cover 106 and is connected to the bottom plate 107, and a positioning pin 109 is provided on the sleeve 108. Further, the transmission device 16 is a rotating sleeve 167 disposed on the through hole 100 and rotatable, and a card slot 166 is provided on the rotating sleeve 167. The rotating sleeve 167 is engaged with the actuator 142 of the fire actuator 14 through the card slot 166, so that the actuator 142 can drive the rotating sleeve 167 to rotate. The rotating sleeve 167 is sleeved on the sleeve 108, and a through slot 168 is provided on the rotating sleeve 167 for the fixing pin 109 to pass through. When in use, the rotating sleeve 167 rotates, and the through slot 168 of the rotating sleeve 167 rotates to the position corresponding to the fixing pin 109, and the fixing pin 109 passes through the through slot 168 to make the sleeve 108 fall. Further, the ejection mechanism 12 includes a plurality of flip plates 122. The preferred ejection mechanism 12 of this embodiment is 4 flip plates 122, which are respectively distributed around the bottom plate 107. Each flip plate 122 is rotatably arranged on the bottom plate 107 through an axis 123. The flip plate 122 is connected to the top cover 106 through a connecting device 20. The connecting device 20 can be a rope, such as a steel wire rope, which can be stacked in the storage mechanism 10, so as to achieve its function. Further, the bottom plate 107 can be a wooden board, a steel plate, or a hollow mesh structure to reduce the overall weight of the bottom plate 107. In order to enhance the supporting force of the bottom plate 107, reinforcing ribs can be arranged on the bottom plate 107. Furthermore, in this embodiment, by providing a temperature sensing probe hole 181 on the storage mechanism 10 and the fire blanket, the temperature device 18 can penetrate the storage mechanism 10 and the fire blanket 11 and extend out of the storage mechanism 11 to the bottom of the storage mechanism 11, so as to immediately sense the temperature under the storage mechanism 11 and enable the fire actuator 14 to perform an execution action.

[0029] The working principle of the second embodiment of the present invention is as follows: the temperature is detected by the temperature sensing device 18. When the temperature sensing device 18 reaches the set temperature, the fire actuator 14 performs an execution action, driving the rotating sleeve 165 to rotate and release the sleeve 108 and the bottom plate 107. The connection device 20 tightened by gravity causes the flip plate 122 to flip axially to pop out and unfold the fire blanket 11, covering the fire point below it to prevent it from spreading.

[0030] Furthermore, the outer periphery of the fire blanket 11 of the present invention is provided with a counterweight block 21, which is a rollable counterweight block 21, preferably four counterweight blocks 21, which are evenly distributed on the edge of the fire blanket 11. When in use, the counterweight blocks 21 are wound inside the fire blanket 11. When the fire blanket 11 is ejected and released by the ejection mechanism 12, the counterweight blocks 21 use gravity and elastic potential energy to drive the fire blanket 11 to descend, and expand the outer periphery of the fire blanket 11, so that the fire blanket 11 covers the fire point as large an area as possible.

[0031] Furthermore, a self-expanding coil spring piece 22 may be provided at the edge of the fire blanket 11. When the fire blanket is rolled up, the coil spring piece 22 and the fire blanket 11 may be synchronously rolled up to allow the fire blanket 11 to further expand after being ejected.

[0032] Furthermore, when the present invention is in use, a steel wire rope (not shown) can be connected to the actuator rod 141 of the fire actuator 14. The steel wire rope is relatively long, and the other end thereof can be arranged at a position farther away from the present invention. When an emergency occurs, the steel wire rope is pulled to drive the actuator rod 14 and the actuator 14 of the fire actuator 14, thereby driving the transmission device 16, releasing the ejection mechanism 12 and the fire blanket 11 to cover the fire point, thereby achieving the purpose of remote operation control.

[0033] The present invention can also be connected to the water pipe of the fire sprinkler head through a pipeline (not shown), and the pipeline connecting the water pipe is inserted into the storage device 10 from the top. When the fire blanket 11 is released from the storage device 10, water is sprayed on the fire blanket 11, which can further improve the fire extinguishing effect.

[0034] In summary, the present invention does not require manual intervention and responds quickly. When the temperature reaches the set value, the fire actuator 14 is automatically triggered to perform the execution action, and the fire blanket 11 and the ejection mechanism 12 are released through the transmission device 16. The fire blanket 11 and the ejection mechanism 12 use their own gravity to separate from the storage mechanism 10, tighten the connecting device 20, and convert it into an ejection force through the ejection mechanism 12, eject the fire blanket 11, and use the weight of the counterweight block 21 to unfold the fire blanket 11, so that the fire blanket 11 is unfolded to cover the fire point, effectively improving the fire extinguishing efficiency. The fire blanket 11 adopts a winding and stacking design, and a counterweight block 21 is arranged on the periphery. It can be quickly unfolded and cover the fire point after being ejected, and isolate the fire source to prevent it from spreading. The design of the storage mechanism 10 and the ejection mechanism 12 enables the fire blanket 11 to be compactly stored in the ceiling space without occupying the floor space, and is convenient for daily inspection and replacement. The overall structure is simple, with few parts, easy to install and maintain, and has a wide range of applications. It can be used in various environments where the fire actuator 14 is installed, such as garages, warehouses, factories, etc., and can effectively improve the fire safety level of these places.
