Description

Technical Field

[0001] The invention relates to the technical field of fireproof sheds, and in particular to a fireproof shed for automobile spontaneous combustion. Background Art

[0002] At present, the rechargeable batteries of electric vehicles are chemically active and flammable. When the rechargeable battery experiences thermal runaway, a violent reaction will occur inside the battery, releasing oxygen and huge amounts of heat. Due to the limited space inside the battery pack, the heat will accumulate in a short period of time. If the heat and gas are not released in time, the battery may burn or even explode. Although the battery explosion is not as powerful as explosives, it will be accompanied by splashes of materials such as copper foil and electrolyte. These materials, with a maximum temperature of nearly 1000°C, will not only burn and corrode the skin, but also form new ignition points, causing damage to other vehicles and nearby objects. If people do not have time to avoid it, they are easily injured.

[0003] In order to solve these major hidden dangers and ensure personal and property safety, some manufacturers have designed a fireproof shed with fireproof function. This type of structure can refer to the automobile fireproof shed disclosed in China Patent Publication No. CN214786390U, which includes a fireproof component, the fireproof component includes a fireproof shed and a frame, the fireproof shed is folded and arranged on the frame, the fireproof shed is unfolded to form a protective space for placing the car, and the fireproof shed is made of flame-resistant membrane material; a moving component, the moving component includes a driver and a guide rail, the frame is connected to the guide rail, and the driver drives the frame to move along the guide rail to unfold the fireproof shed; a fire-fighting component, the fire-fighting component includes a smoke sensor and a sprinkler device, and the smoke sensor and the sprinkler device are arranged on the fire-fighting component; a control system, the control system drives the driver to unfold or fold the fireproof shed, and the control system receives the smoke signal transmitted by the smoke sensor to turn on the sprinkler device.

[0004] However, the existing car fire shed needs to set rails on the ground parking space, and then set the fire shed on the rails, and drive the fire shed to unfold through the driver. This structure has the following problems: 1. Each parking space needs to be equipped with a car fire shed, which is costly, and the guide rails are installed on the parking space, which takes up a lot of space and also brings certain pressure to the user's parking and storage. It is also necessary to regularly clean the debris on the track; 2. The fire shed needs to be moved to the side of the self-igniting electric car and positioned properly. Since the fire shed is easy to shake during the extension process, it is usually necessary to manually position one end of the fire shed so that the fire shed can be smoothly extended. The spontaneous combustion of the car may be accompanied by an explosion. If people are close to the self-igniting car, there will be a great safety hazard.

[0005] Therefore, the above problems need to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0054] The implementation modes of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0055] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0056] Example 1

[0057] Please refer to Figure 1-12 As shown, the present embodiment discloses a car self-ignition fireproof shed, comprising:

[0058] Frame 10;

[0059] The telescopic assembly 20 is disposed in the frame 10, and the telescopic assembly 20 can extend forward outside the frame 10 to form a fireproof space surrounding the automobile 50;

[0060] A driving assembly 30, used for driving the telescopic assembly 20 to telescope in the front-rear direction;

[0061] The positioning assembly includes a cross bar 12 disposed at the bottom of the front end of the frame 10 and used to block the wheels of the car 50 in the front-to-back direction, and a positioning and fixing module used to fix the frame 10 to the two wheels of the car 50 in the front-to-back and left-to-right directions;

[0062] The fire extinguishing assembly is arranged inside the frame 10 and can spray the fire extinguishing agent toward the fireproof space.

[0063] The telescopic fireproof canopy of this embodiment can be used in situations where a car spontaneously ignites, such as Figure 1 to Figure 2 As shown, if a spontaneous combustion accident occurs in the car 50 while charging, the retractable fire shelter can be moved to the rear of the spontaneously combusting car 50 by means of a manual or intelligent mobile device, without the need to set up guide rails and other structures on each ground parking space, thereby reducing costs. The telescopic component 20 is driven forward by the driving component 30 to extend out of the frame 10 to form a fireproof space surrounding the car 50, thereby blocking the flames of the spontaneously combusting car 50 and preventing the spontaneously combusting car 50 from spreading to the cars 50 on the left and right sides, thereby buying more than half an hour for firefighting and rescue.

[0064] The telescopic fireproof shed of this embodiment, please refer to Figure 5 and Figure 6 By setting up the fire detection device 60, when a fire occurs, the fire detection tube 63 can be extended forward along with the extension of the telescopic assembly 20, so that the fire detection tube 63 is stretched to the upper side of the fire source. At the same time, detection is performed at many detection points along the fire detection tube 63. The fire detection tube 63 is softened and exploded at the highest heat temperature, and the fire extinguishing agent is directly released to the self-igniting car 50 through the fire detection tube 63 itself, so that the flame of the car 50 is extinguished.

[0065] It should be noted that the fire detection tube 63 is a high-tech non-metallic synthetic product, which has the good characteristics of long-term leakage resistance, good flexibility and effective temperature sensitivity. The fire detection tube 63 explodes within a certain temperature range and sprays the fire extinguishing agent to act on the protected area. It does not require complex equipment and pipelines and has a simple structure.

[0066] In addition, before the telescopic assembly 20 is extended, the fire detection tube 63 is folded and arranged on the lower end surface of the mounting plate 61. Specifically, the folded fire detection tube 63 can be adhered to the lower end surface of the mounting plate 61 with adhesive tape. When the fire detection tube 63 is pulled, the adhesive tape is torn off so that the fire detection tube 63 can be extended forward. As another embodiment, a left-right through-type shelf plate can be provided at the lower end of the mounting plate 61, and the folded fire detection tube 63 can be placed on the shelf plate. The folding placement of the fire detection tube 63 and its extension during a fire can also be achieved.

[0067] Further, such as Fig.11 and Fig.12As shown, the driving assembly 30 of this embodiment is arranged in the frame 10, and the driving assembly 30 includes a scissor arm 31, a slider 32 hinged to the upper and lower arms at the rear end of the scissor arm 31, a tension spring 33 connected between the two sliders 32, and a reset mechanism 34 for driving the two sliders 32 to move in opposite directions; the two sliders 32 slide on the frame 10 in the up-down direction; the front end of the scissor arm 31 is hinged to the telescopic assembly 20 to drive the telescopic assembly 20 to telescope in the front-back direction. The driving assembly 30 of this embodiment adopts a mechanical structure. After the switch of the driving assembly 30 is turned on, the tension of the tension spring 33 is used to make the two sliders 32 move relative to each other in the up-down direction, and the two sliders 32 drive the scissor arm 31 to extend forward, thereby driving the telescopic assembly 20 to extend forward outside the frame 10 to form a fireproof space surrounding the car 50. The mechanical driving structure can make the telescopic assembly 20 not be affected by the high temperature of the fire and extend smoothly, ensuring that the telescopic assembly 20 covers the spontaneously combusting car 50 to separate the flames generated by the spontaneously combusting car 50.

[0068] Please refer to Figure 8 In this embodiment, the inner side of the frame 10 is provided with a plurality of first fireproof panels 11 which close the hollow positions of the frame 10. The first fireproof panels 11 can be fixed to the frame 10 by bolts. When the first fireproof panels 11 are burned, they can be disassembled and replaced, thereby extending the service life of the telescopic fireproof shed.

[0069] As a preferred embodiment, the first fireproof board 11 of this embodiment can be made of fireproof materials such as mineral wool board, cement board, perlite board, fireproof gypsum board, calcium carbonate fiberboard, magnesium oxychloride fireproof board, etc., and has good fireproof performance.

[0070] Please refer to Fig.11 The telescopic assembly 20 of this embodiment includes at least two layers of fireproof inner frames 21 which are sequentially sleeved from the inside to the outside, a second fireproof plate 22 fixed on the fireproof inner frame 21, and a second caster 23 arranged at the bottom of the fireproof inner frame 21. The front end of the scissor arm 31 is hinged to the outermost fireproof inner frame 21 through a rotating shaft. By arranging more than two layers of fireproof inner frames 21, the length of each layer of fireproof inner frames 21 along the front-to-back direction can be shortened under the condition of the same maximum extension distance. Since all fireproof inner frames 21 can be retracted into the frame 10, the length of the frame 10 along the front-to-back direction can be shortened, the structure is more compact, and the space occupied is smaller.

[0071] Moreover, by setting a second caster 23 at the bottom of the fireproof inner frame 21, the fireproof inner frame 21 is driven to move in the front-to-back direction by the second caster 23, thereby reducing the movement resistance of the fireproof inner frame 21, which is conducive to the driving component 30 driving the fireproof inner frame 21 to move in the front-to-back direction.

[0072] Please refer to Figure 6 and Figure 7In this embodiment, a slide rail assembly 24 that can be extended and retracted along the front-to-back direction is provided between the frame 10 and the innermost fireproof inner frame 21, and a slide rail assembly 24 that can be extended and retracted along the front-to-back direction is provided between two adjacent fireproof inner frames 21. The slide rail assembly 24 includes a fixed slide rail 241 and a movable slide rail 242. The fixed slide rail 241 and the movable slide rail 242 are both heavy-loaded slide rails, which can withstand greater gravity without deformation, thereby improving the stability of the fireproof inner frame 21 in the extension and retraction along the front-to-back direction.

[0073] Please refer to Fig.11 A pulling structure 25 is provided at the rear end of each layer of fireproof inner frame 21. The pulling structure 25 can adopt a baffle. When the rear end of the outermost fireproof inner frame 21 moves to the front end of the fireproof inner frame 21 inside it, the baffle blocks the front end of the fireproof inner frame 21 inside it, thereby driving the fireproof inner frame 21 inside it to move forward. Similarly, the multi-layered fireproof inner frames 21 can be pulled and unfolded toward the front in sequence through the pulling structure 25.

[0074] For further information, please refer to Figure 8 A baffle 26 is provided at the front end of the outermost fireproof inner frame 21. When the scissor arm 31 contracts and drives the outermost fireproof inner frame 21 to move backward, due to the blocking effect of the baffle 26 on other fireproof inner frames 21, the baffle 26 drives the remaining fireproof inner frames 21 to return to the rear side and shrink into the frame 10.

[0075] Please refer to Fig.12 The reset mechanism 34 includes a turntable 341 rotatably arranged in the middle of the front end of the frame 10, and pulleys 342 rotatably arranged on the upper and lower sides of the front end of the frame 10. Both sliders 32 are connected with pull ropes 343. The upper pull rope 343 passes through the upper pulley 342 and is connected to the turntable 341. The lower pull rope 343 passes through the lower pulley 342 and is connected to the turntable 341. The turntable 341 is connected with a handle 344. When the telescopic assembly 20 needs to be retracted and reset, the user can shake the handle 344 to rotate the turntable 341, so that the upper and lower pull ropes 343 respectively pull the upper and lower sliders 32 to move in opposite directions in the up and down directions to drive the scissor arm 31 to retract. The operation is simple.

[0076] For further information, please refer to Fig. 9 and Fig.10The driving assembly 30 of this embodiment also includes a locking mechanism 35, which includes a ratchet 351 fixed to the turntable 341, a pawl 352 fixed to the frame 10 and capable of locking the ratchet 351, and a control box 353 for driving the pawl 352. The control box 353 is fixed to the frame 10 and has a push switch 354 on the outside. When the telescopic assembly 20 is in a retracted state, the ratchet 351 is locked by the pawl 352, thereby preventing the turntable 341 from deflecting, and having good structural stability; when the user needs to extend the telescopic assembly 20, the push switch 354 can be pressed, and the control box 353 controls the pawl 352 to swing, and the pawl 352 no longer locks the ratchet 351. Under the tension of the tension spring 33, the two sliders 32 move relative to each other, so that the scissor arm 31 extends and deforms forward, driving the outermost fireproof inner frame 21 to move forward, and the structure is ingenious.

[0077] For further information, please refer to Fig.12 The present embodiment has two groups of driving components 30, which are respectively arranged on the left and right sides of the frame 10. Two adjacent turntables 341 are connected by a transmission rod 345, and the two groups of driving components 30 are linked by the transmission rod 345, which has an ingenious structure.

[0078] The telescopic fire shelter of this example is moved manually. Specifically, the moving device uses four first casters 41, so that the telescopic fire shelter can be quickly pushed to a predetermined position. The use of the first casters 41 also reduces the cost of the equipment, which is conducive to large-scale production.

[0079] For further information, please refer to Figure 8 The positioning and fixing module includes a second positioning mechanism and a fixing mechanism; the second positioning mechanism includes a first limiting rod 13 and a second limiting rod 14 fixed to the front end of the cross bar 12 on both sides along the left and right directions, and a limiting area for limiting the wheels of the automobile 50 along the left and right directions is formed between the first limiting rod 13 and the second limiting rod 14; the fixing mechanism includes a brake device 43 arranged on the first caster 41.

[0080] In this embodiment, a positioning and fixing module is provided. When a manual or intelligent mobile device moves the fireproof shed to the rear of the self-igniting car 50, the cross bar 12 is used to support the rear end of the wheel of the car 50, and then the first limiting rod 13 and the second limiting rod 14 are used to limit the two wheels of the car 50 to the left and right, so that the two wheels are located in the limiting area formed between the first limiting rod 13 and the second limiting rod 14 to prevent the frame 10 from shaking in the left and right directions. After the left and right positioning is achieved, the brake device 43 is used to lock the first caster 41 to ensure that the telescopic component 20 of the fireproof shed can be extended forward. The left and right positioning of the frame 10 and the forward extension of the telescopic component 20 can be achieved through the cooperation of the first limiting rod 13, the second limiting rod 14 and the brake device 43. The structure is simple. After the brake is stopped, the operator can press the push switch 354, and the driving component 30 drives the telescopic component 20 to extend forward. The operator does not need to manually fix the frame 10 to avoid fire injuries.

[0081] Furthermore, the spacing between the first limiting rod 13 and the second limiting rod 14 is adjustable. Specifically, mounting holes along the left-right direction are set on the cross bar 12, and the first limiting rod 13 and the second limiting rod 14 are fixed to the mounting holes by two bolts respectively. According to the distance between the two wheels of the automobile 50, the mounting positions of the two bolts are adjusted to achieve the spacing adjustment of the first limiting rod 13 and the second limiting rod 14.

[0082] Example 2

[0083] Please refer to Figure 13 to Figure 15 The difference between this embodiment and embodiment 1 is that the positioning and fixing module of this embodiment adopts a first positioning mechanism and a quick fixing mechanism; the first positioning mechanism includes a cross bar 12 provided at the bottom of the front end of the frame 10 and used to block the wheels of the car 50 along the front and rear directions, and mounting frames 15 are provided at both ends of the cross bar 12; the quick fixing mechanism includes a first hook 16 and a second hook 17 rotatably provided on the two mounting frames 15, a first spring 18 connected to the cross bar 12 and pulling the first hook 16 to the left, and a second spring 19 connected to the cross bar 12 and pulling the second hook 17 to the right, and the first hook 16 and the second hook 17 can be extended between the two wheels of the car 50 to respectively clamp the inner sides of the two wheels of the car 50.

[0084] By setting the first positioning mechanism and the quick fixing mechanism, the fireproof shed can be moved to the rear of the spontaneously combusting car 50 by means of a manual or intelligent mobile device, and then the frame 10 of the fireproof shed is aligned with the car 50, and the frame 10 is continuously driven to move forward, so that the first hook 16 and the second hook 17 extend between the two wheels of the car 50, respectively clamping the inner sides of the two wheels of the car 50, and utilizing the tension of the first spring 18 and the second spring 19 to stably clamp the inner sides of the two wheels of the car 50 to prevent the frame 10 from shaking in the left and right directions, thereby realizing quick left and right positioning, and the rear ends of the two wheels of the car 50 are limited by the cross bar 12, and the front and rear fixation of the frame 10 is realized by the cooperation of the hook parts of the first hook 16 and the second hook 17 with the cross bar 12. After the front, rear, left and right fixation is completed, the operator can press the push switch 354, and the drive assembly 30 drives the telescopic assembly 20 to extend forward, and the operator does not need to manually fix the frame 10, thereby avoiding fire injuries to personnel.

[0085] Due to the pulling force of the first spring 18 and the second spring 19, the first hook 16 and the second hook 17 have a tendency to swing in opposite directions. In order to make the first hook 16 and the second hook 17 easier to be clamped into the inner side of the wheel of the automobile 50, further, the front end of the first hook 16 is provided with a first inclined surface 161 for guiding the first hook 16 to be clamped into the inner side of the wheel of the automobile 50. When the first inclined surface 161 contacts the wheel of the automobile 50, the elastic effect of the first spring 18 and the guiding effect of the first inclined surface 161 are utilized to enable the first hook 16 to be quickly clamped into the inner side of the wheel of the automobile 50; the front end of the second hook 17 is provided with a second inclined surface 171 for guiding the second hook 17 to be clamped into the inner side of the wheel of the automobile 50. When the second inclined surface 171 contacts the wheel of the automobile 50, the elastic effect of the second spring 19 and the guiding effect of the second inclined surface 171 are utilized to enable the second hook 17 to be quickly clamped into the inner side of the wheel of the automobile 50.
