Description

Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, specifically to a passive mobile fireproof cover that delays the spread of car fires in underground garages. Background Technology

[0002] With the vigorous development and use of new energy (electric) vehicles, cases of spontaneous combustion have been occurring frequently. In particular, there have been increasing cases where spontaneous combustion has occurred when new energy vehicles are parked or being charged in underground garages, and the fire has quickly spread to other vehicles parked in the same garage. The resulting losses are enormous and the consequences are very serious.

[0003] Currently, when a large number of new energy vehicles catch fire, if spontaneous combustion occurs, it is very easy for the fire to spread to other vehicles or materials. No matter what kind of fire extinguishing medium is used, it is impossible to extinguish the fire quickly. This can easily cause the fire to spread to other vehicles and combustibles, resulting in huge property losses. Therefore, the purpose of this fireproof cover is to protect other vehicles and combustibles closest to the fire source, prevent the flames from affecting the surrounding materials during the combustion process, and minimize the chain reaction losses caused by the spread of the fire. Utility Model Content

[0004] This invention proposes a passive mobile fireproof cover that delays the spread of car fires in underground garages, solving the problem in related technologies where spontaneous combustion of new energy vehicles can easily spread to other vehicles or materials, resulting in huge property losses.

The two sets of bracket fixing parts are staggered and the remaining main supports are slidably connected to the two sets of bracket fixing parts through sliders. Telescopic scissor frames are installed on both sides of multiple main support structures; Slides are provided on both sides of the main support frame; The slider 1 is slidably connected to the slide groove inside the main body support on the rear side; The second slider is slidably connected to the groove inside the other main supports. The upper end of the telescopic scissor frame is movably connected to multiple main supports respectively, and the lower end of the telescopic scissor frame is movably connected to slider one and slider two respectively. And a power mechanism mounted on the main support for driving the slider to move.

[0006] Preferably, the power mechanism includes a motor fixedly installed on the bottom wall of the slide groove of the main body support on the rear side, and a lead screw fixedly connected to the output end of the motor. The lead screw and the slider are threadedly connected, and the top end of the lead screw is rotatably connected to the top wall of the slide groove.

[0007] Preferably, the bottom sides of the fire blanket are connected with fireproof finials, which are made of fireproof material.

[0008] Preferably, the detection mechanism includes two fixing blocks fixedly installed on one side of the main body support on the front side, a smoke sensor fixedly installed on one end of the fixing blocks, and a controller fixedly installed on one side of the main body support on the rear side.

[0009] Preferably, the main support frame is equipped with a water spray mechanism to prevent the spread of fire.

[0010] The water spraying mechanism includes two mounting plates fixedly installed on one side of the main support frame at the rear, a water tank fixedly installed on the top of the mounting plates, a pump body fixedly installed on the top of the water tank, a connecting pipe fixedly connected to the output end of the pump body, and water spraying hoses fixedly installed on both sides of the surface of the fireproof blanket.

[0012] The working principle and beneficial effects of this utility model are as follows: This device can be stored in an underground garage as a fire-fighting facility. When there is no fire, it is in a retracted state and can be tested by a testing agency. When a fire occurs and it needs to be used, a motor drives a lead screw to rotate, causing slider one to slide upwards, thus unfolding the telescopic scissor frame. The telescopic scissor frame then drives slider two upwards, allowing the telescopic scissor frame, aided by casters, to push the main support frame outwards and quickly move to the locations of vehicles or materials requiring passive fire protection on either side of the fire source. This causes a fire blanket to unfold and cover the fire source, effectively protecting the main support frame and the covered vehicles or materials. Therefore, it prevents the fire from spreading to other vehicles or materials, reducing property damage and effectively improving fire prevention and overall fire safety. It is also reusable.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0016] Please see Figure 1 - Figure 6 The present invention provides a passive mobile fireproof cover for delaying the spread of car fire in an underground garage, comprising: several linearly arranged main support brackets 1, and a detection mechanism for monitoring fire on the main support brackets 1; Casters 2 are fixedly installed at the bottom of the main support frame 1; Fireproof blanket 3 is fixedly attached to the surface of the main support 1; Two sets of bracket fixing parts 4 are fixedly installed on the two sides of the front and rear main brackets 1 respectively. The two sets of bracket fixing parts 4 are staggered. The remaining main brackets 1 are slidably connected to the two sets of bracket fixing parts 4 through sliders. When the main bracket 1 is folded, its folded thickness is adapted to the length of the bracket fixing parts 4. Telescopic scissor frames 5 are installed on both sides of multiple main support frames 1; Slide grooves are provided on both sides of the main support frame 1; The slider 6 is slidably connected to the groove inside the main body support 1 on the rear side; The second slider 7 is slidably connected to the groove inside the other main support 1. The upper end of the telescopic scissor frame 5 is movably connected to multiple main supports 1 respectively, and the lower end of the telescopic scissor frame 5 is movably connected to the first slider 6 and the second slider 7 respectively. And a power mechanism mounted on the main support 1 for driving the slider 6 to move.

[0017] The power mechanism includes a motor 8 fixedly installed on the bottom wall of the slide groove of the main support 1 on the rear side, and a lead screw 9 fixedly connected to the output end of the motor 8. The lead screw 9 and the slider 6 are threadedly connected, and the top end of the lead screw 9 is rotatably connected to the top wall of the slide groove.

[0018] The technical solution provided in this embodiment is as follows: During use, the entire device can be stored in an underground garage as a fire-fighting facility. For example, when placed at the rear of a vehicle, it is in a retracted state when there is no fire, making it lightweight and space-saving. The sides of the vehicle are inspected by a testing agency. When a fire occurs and the device needs to be used, the motor 8 on the fireproof covers on both sides of the fire source drives the lead screw 9 to rotate, causing the slider 6 to slide upwards in the groove of the rear main support 1. This unfolds the telescopic scissor frame 5, and the telescopic scissor frame 5 drives the slider 7 to slide upwards in the groove on the remaining main support 1, thus allowing the telescopic scissor frame 5 to move... Under the action of the caster 2, the main support 1 is pushed to unfold and quickly move to the position of the vehicles or materials that need passive fire protection on both sides of the fire source, and the fire blanket 3 unfolds to cover them and block the fire source. The fire blanket 3 covers all the main supports 1, effectively protecting the main supports 1 and also protecting the covered vehicles or materials. Therefore, it achieves the effect of preventing the fire from spreading to other vehicles or materials, which helps to reduce property losses and effectively improves the fire prevention and control effect and the overall fire safety. After the fire is extinguished, the reversible motor 8 causes the main support 1 to drive the fire blanket 3 to retract and fold for subsequent reuse.

[0019] Furthermore, fireproof burrs 10 are connected to both sides of the bottom of the fire blanket 3. The fireproof burrs 10 are made of fireproof material, and the fireproof burrs 10 are made of the same material as the fire blanket 3.

[0020] Specifically, by setting the fireproof finial 10, flames can be prevented from entering the enclosure from the bottom, completely blocking the flames.

[0021] Furthermore, the detection mechanism includes two fixing blocks 11 fixedly installed on one side of the main body bracket 1 on the front side, a smoke sensor 12 fixedly installed on one end of the fixing block 11, and a controller 13 fixedly installed on one side of the main body bracket 1 on the rear side. The smoke sensor 12 and the motor 8 are both electrically connected to the controller 13, and the controller 13 is connected to the control system of the underground garage.

[0022] Specifically, the smoke sensor 12 can detect both sides of the protected vehicle. When a smoke fire is detected on one side, the information is fed back to the controller 13 so that the fireproof cover can be moved and deployed for protection.

[0023] Furthermore, a rear fireproof cloth 19 is fixedly installed on one side of the rear main support 1. The rear fireproof cloth 19 is in a rolled-up state. Two fixing straps 20 for wrapping the rear fireproof cloth 19 are fixedly installed on one side of the rear main support 1. A magnet 21 is fixedly connected to one end of the fixing straps 20. An electromagnet 22 that is magnetically connected to the magnet 21 is fixedly installed on one side of the rear main support 1. The rear fireproof cloth 19 and the fireproof blanket 3 are made of the same material. The electromagnet 22 and the controller 13 are electrically connected.

[0024] Specifically, in the event of a fire, when this fireproof cover is deployed and moved to the isolated vehicle or material, the controller 13 can be used to de-energize the electromagnet 22 as needed, so that it is no longer attracted to the magnet 21, and the fixing strap 20 hangs down naturally, thereby causing the fireproof cloth 19 at the rear end to be lowered by gravity and unfolded, so as to block the rear of the fireproof cover and prevent flames from entering from the rear, thus ensuring the comprehensive use of the fireproof cover. Example 2

[0025] Based on Embodiment 1, in this embodiment: the main support 1 is provided with a water spraying mechanism to prevent the spread of fire.

[0026] The sprinkler system includes two mounting plates 14 fixedly installed on one side of the main support 1 at the rear, a water tank 15 fixedly installed on the top of the mounting plate 14, a pump body 16 fixedly installed on the top of the water tank 15, a connecting pipe 17 fixedly connected to the output end of the pump body 16, and sprinkler hoses 18 fixedly installed on both sides of the surface of the fire blanket 3. The surface of the sprinkler hoses 18 is equipped with multiple nozzles. The two connecting pipes 17 are respectively connected to the two sprinkler hoses 18. The top of the water tank 15 is equipped with a water injection pipe. The input end of the pump body 16 extends into the water tank 15 through a pipe. The pump body 16 is electrically connected to the controller 13. The sprinkler hoses 18 are made of fire-resistant materials, such as fire hydrant pipes.

[0027] The technical solution provided in this embodiment is as follows: when the fireproof cover is deployed, the detection mechanism detects which side of the car is on fire, and the controller 13 controls the pump body 16 at the corresponding position to draw water from the water tank 15, which is then delivered and sprayed out through the connecting pipe 17 and the spray hose 18, thereby enabling water spraying to extinguish the fire on the car and prevent the fire from spreading.

[0028] It should be noted that all electrical components in this utility model, such as motor 8, smoke sensor 12, controller 13, etc., are powered separately by the fire protection power supply system of the underground garage. The purpose is to ensure that they can be used normally like fire protection equipment in the event of a fire, so as to prevent the spread of fire. In addition, the control system of this device is connected to the fire control system and adopts synchronous control technology, which enables the motors 8 on both sides to start synchronously.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
