Description

Technical Field

[0001] This invention relates to the field of civil defense room design, and in particular to civil defense basements with self-ignition isolation structures for new energy vehicles. Background Technology

[0002] Civil defense basements are commonly used parking areas for new energy vehicles. Their relatively enclosed interiors result in high vehicle density. When a new energy vehicle spontaneously combusts inside a civil defense basement, the fire spreads rapidly and generates large amounts of high-temperature smoke. Currently, most civil defense basements lack precisely movable isolation structures specifically designed to prevent spontaneous combustion of new energy vehicles. Existing protective measures primarily consist of fixed fire compartments, manual fire extinguishers, and fire sprinkler systems. These measures are insufficient to accurately contain and isolate a burning new energy vehicle, making it difficult to control the fire's spread in its early stages. This can easily lead to the fire spreading to nearby parked vehicles and potentially damaging the main structure and internal facilities of the civil defense basement, affecting its safe use and subsequent emergency response. Summary of the Invention

[0003] The present invention aims to improve at least one technical problem in the prior art.

[0004] This invention provides a civil defense basement with a new energy vehicle self-ignition isolation structure, comprising: Inner frame; A first linear drive mechanism is provided on the inner frame in the left-right direction; The second linear drive mechanism is disposed on the movable part of the first linear drive mechanism along the front-back direction; A telescopic isolation shed, which is deployed by a second linear drive mechanism; A flame sensor is installed on the inner frame to identify the ignition point. The flame sensor is signal-connected to both the first linear drive mechanism and the second mechanism, so that the first linear drive mechanism and the second linear drive mechanism drive the telescopic isolation shed to move to the location of the ignition point according to the signal from the flame sensor.

[0005] The beneficial effects of this invention are as follows: the coordinated arrangement of the inner frame, the first linear drive mechanism, the second linear drive mechanism, the telescopic isolation shed, and the flame sensor allows the flame sensor to accurately identify the ignition point and transmit signals. The dual linear drive mechanism can drive the telescopic isolation shed to move precisely to the ignition point and unfold, thus isolating the spontaneously combusting new energy vehicle, reducing the spread of the fire to a certain extent, and improving the impact of the fire on surrounding vehicles and the structure of the civil defense basement.

[0006] As a sub-solution of the above technical solution, the retractable isolation shed includes a U-shaped shed body, and there are multiple shed bodies. Adjacent shed bodies are nested inside each other, and adjacent shed bodies are slidably connected by a connecting structure to prevent them from detaching from each other. The first canopy is located on the inner side, and the last canopy is located on the outermost side. The second linear drive mechanism includes a second base and a second slide. The second base is driven by the first linear drive mechanism, and the second slide slides along the second base. The first canopy is fixedly connected to the second base, and the last canopy is transitionally connected to the second slide.

[0007] As some sub-solutions of the above technical solution, the connection structure includes a first guide rail, a second guide rail, a first limiting block and a second limiting block.

[0009] As some sub-solutions of the above technical solution, the first linear drive mechanism includes a first base, a first drive motor, a first lead screw, a first slide rail, a first slide table, a first nut, and a first slider.

The second linear drive mechanism is disposed on the first slider, and the movable part is the first slide table. Overall, the first linear drive mechanism adopts the form of first lead screw drive. On the one hand, compared with the use of cylinders and electric push rods, the overall stroke of the first linear drive mechanism is shorter. On the other hand, the first drive motor can be installed outside the parking space of the civil defense basement, away from the fire point, effectively reducing the failure problem caused by the heat of the fire affecting the drive motor.

[0011] As a sub-solution of the above technical solution, a connecting rod is provided on the top side of the first canopy, and the top side of the connecting rod is fixedly connected to the second base. Fixing the connecting rod to the base reduces heat transfer.

Detailed Implementation

[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The following is combined Figures 1 to 5 Embodiments of the present invention will be described.

[0019] In existing civil defense basements, when a new energy vehicle spontaneously combusts, there is a lack of an isolation structure that can be precisely moved to the ignition point, allowing the fire to spread rapidly and causing damage to surrounding vehicles and the basement structure. This embodiment provides a civil defense basement with an isolation structure for spontaneous combustion of new energy vehicles, including an inner frame 1; a first linear drive mechanism 2, which is mounted on the inner frame 1 in a left-right direction; a second linear drive mechanism 3, which is mounted on the movable part of the first linear drive mechanism 2 in a front-back direction; a telescopic isolation shed 4, which is driven to unfold by the second linear drive mechanism 3; and a flame sensor 5, which is mounted on the inner frame 1 and used to identify the ignition point. The flame sensor 5 is signal-connected to both the first linear drive mechanism 2 and the second linear drive mechanism 3, so that the first linear drive mechanism 2 and the second linear drive mechanism 3 drive the telescopic isolation shed 4 to move to the location of the ignition point according to the signal from the flame sensor 5. When a new energy vehicle spontaneously combusts in a civil defense basement, the flame sensor 5 quickly identifies the location of the fire and transmits a signal to the first linear drive mechanism 2 and the second linear drive mechanism 3. The first linear drive mechanism 2 moves the second linear drive mechanism 3 and the telescopic isolation shed 4 in the left-right direction, and the second linear drive mechanism 3 drives the telescopic isolation shed 4 to unfold in the front-back direction, so that the telescopic isolation shed 4 accurately covers the fire point, forms a barrier against the fire, reduces the spread of the fire to a certain extent, and improves the impact of the fire on the surrounding environment.

[0020] Existing telescopic isolation sheds 4 are mostly integral structures, which cannot flexibly extend and retract to adapt to different fire points, and their connection stability is poor, making them prone to detachment. Further, in one embodiment of the present invention, the telescopic isolation shed 4 includes a U-shaped shed body 41, with multiple shed bodies 41 nested inside each other. Adjacent shed bodies 41 are slidably connected by a connecting structure 6 to prevent them from detaching. The innermost shed body 41 is designated as the first shed body 411, and the outermost shed body 41 is designated as the last shed body 412. The second linear drive mechanism 3 includes a second base 31 and a second slide 32. The second base 31 is driven by the first linear drive mechanism 2, and the second slide 32 slides along the second base 31. The first shed body 411 is fixedly connected to the second base 31, and the last shed body 412 is transitionally connected to the second slide 32. When the second linear drive mechanism 3 is running, the second slide table 32 slides along the second base 31, driving the last canopy 412 to move. Since the adjacent canopies 41 are connected by the inner and outer nested sliding connection structure 6, the last canopy 412 can drive the middle canopy 41 to gradually unfold, realizing the telescopic isolation canopy 4 to extend and retract, adapting to the coverage requirements of different fire points. At the same time, the connection structure 6 can prevent the adjacent canopies 41 from detaching, improving the operational stability of the telescopic isolation canopy 4.

[0021] Furthermore, in one embodiment of the present invention, the connecting structure 6 includes a first guide rail 61, a second guide rail 62, a first limiting block 63, and a second limiting block 64. The first guide rail 61 and the second guide rail 62 are respectively fixed on two adjacent canopies 41. The first guide rail 61 and the second guide rail 62 are slidably connected. The first limiting block 63 is installed on the side of the first guide rail 61 away from the first canopy 411, and the second limiting block 64 is installed on the side of the second guide rail 62 adjacent to the first canopy 411. When adjacent canopies 41 slide relative to each other, the first guide rail 61 and the second guide rail 62 cooperate to guide the movement, ensuring accurate sliding direction and preventing canopy 41 from deviating. When the canopy 41 is extended to its maximum stroke, the first limiting block 63 and the second limiting block 64 abut against each other, restricting further sliding of adjacent canopies 41, preventing canopies 41 from deviating from the preset trajectory, and ensuring the reliability of the telescopic isolation canopy 4's telescopic movement.

[0022] Furthermore, in one embodiment of the present invention, the first guide rail 61 is C-shaped, the second guide rail 62 is C-shaped, and the first limiting block 63 is provided with a clearance groove 631 that matches the shape of the second guide rail 62. The second guide rail 62 passes through the clearance groove 631, and the second limiting block 64 is located inside the first guide rail 61. The C-shaped structure of the first guide rail 61 and the second guide rail 62 fits more tightly, the sliding process is smoother, and the jamming phenomenon is reduced. The clearance groove 631 provides clearance space for the second guide rail 62, avoiding interference between the first limiting block 63 and the second guide rail 62. At the same time, the second limiting block 64 is located inside the first guide rail 61, further optimizing the limiting fit relationship, making the limiting effect more reliable, and improving the overall stability of the connection structure 6.

[0023] Existing linear drive mechanisms mostly use cylinders or electric push rods, which have poor stroke adaptability and the drive motors are susceptible to failure due to fire and temperature rise, making it impossible to guarantee the continuous operation of the isolation structure. Further, in one embodiment of the present invention, the first linear drive mechanism 2 includes a first base 21, a first drive motor 22, a first lead screw 23, a first slide rail 24, a first slide table 25, a first nut 26, and a first slider 27. The first base 21 is disposed on the top side of the inner frame 1. The first drive motor 22 is disposed on the first base 21 and is drivenly connected to the first lead screw 23. The first slide rail 24 is fixed on the first base 21. The first nut 26 and the first slider 27 are both fixed on the first slide table 25. The first nut 26 is threadedly connected to the first lead screw 23, and the first slider 27 is slidably connected to the first slide rail 24. The second linear drive mechanism 3 is disposed on the first slide table 25, and the movable part is the first slide table 25. During operation, the first drive motor 22 drives the first lead screw 23 to rotate. The first lead screw 23, through its threaded engagement with the first nut 26, moves the first slide table 25. The first slider 27 slides along the first slide rail 24 for guidance, driving the second linear drive mechanism 3 to move in the left and right directions. Compared with cylinders and electric push rods, the first lead screw 23-driven mechanism is more adaptable to the installation space of underground air-raid shelters. The overall stroke better meets the usage requirements. Furthermore, the first drive motor 22 is installed outside the parking space of the underground air-raid shelter, away from the fire point, which reduces the impact of fire heating on the drive motor, reduces the probability of motor failure, and ensures the stable operation of the first linear drive mechanism 2.

[0024] Further, in one embodiment of the present invention, the second linear drive mechanism 3 includes a second base 33, a second drive motor 34, a second lead screw 35, a second slide rail 36, a second slide table 37, a second nut 38, and a second slider 39. The second base 33 is disposed on the first slide table 25, the second drive motor 34 is disposed on the second base 33, and the second drive motor 34 is drivenly connected to the second lead screw 35. The second slide rail 36 is fixed on the second base 33. The second nut 38 and the second slider 39 are both fixed on the second slide table 37. The second nut 38 is threadedly connected to the second lead screw 35, and the second slider 39 is slidably connected to the second slide rail 36. The first end chamber 411 is fixedly connected to the second base 33, and the last end chamber 412 is fixedly connected to the second slide table 37. During operation, the second drive motor 34 drives the second lead screw 35 to rotate. The second lead screw 35, through its threaded engagement with the second nut 38, drives the second slide table 37 to slide along the second slide rail 36. The second slider 39 is guided along the second slide rail 36, driving the final canopy body 412 to move, thus realizing the expansion and contraction of the telescopic isolation canopy 4. This structure improves the operating accuracy and stability of the second linear drive mechanism 3, ensures efficient power transmission, and can accurately drive the telescopic isolation canopy 4 to cover the fire point, ensuring the isolation effect.

[0025] The first canopy 41 is directly connected to the second base 31. Heat generated at the ignition point can easily be transferred to the drive mechanism through the canopy 41, affecting the normal operation of the drive components. Further, in one embodiment of the invention, a connecting rod 7 is provided on the top side of the first canopy 411, and the top side of the connecting rod 7 is fixedly connected to the second base 33. The connecting rod 7 separates the first canopy 411 from the second base 33 by a certain distance, reducing the transfer of heat generated at the ignition point from the canopy 41 to the second base 33 and the second linear drive mechanism 3, thus reducing the impact of heat on the drive components, improving the operational reliability of the drive mechanism, and ensuring the continuous functioning of the isolation structure.

[0026] Furthermore, in one embodiment of the present invention, a reinforcing rib 8 is provided between the connecting rod 7 and the second base 33. The reinforcing rib 8 can enhance the structural strength of the connection between the connecting rod 7 and the second base 33, improve the connection stability, disperse the force generated during operation, prevent the connection from deforming or breaking due to force, ensure the overall stability of the telescopic isolation shed 4, and ensure that the isolation action is completed normally.

[0027] The canopy 41 relies solely on its own structure for isolation, resulting in poor fire resistance. Fire can easily penetrate the canopy 41 and spread, failing to effectively block the fire. Furthermore, in one embodiment of the invention, a fireproof board 9 is provided on the inner side of the canopy 41. The fireproof board 9 enhances the fire resistance of the telescopic isolation canopy 4, improves its ability to block fire, reduces the possibility of fire penetrating the canopy 41 and spreading, further mitigating the impact of spontaneous combustion on surrounding vehicles and the structure of the underground civil defense shelter, and improving the isolation effect.

[0028] The existing fireproof board 9 material has only average fireproof and heat insulation performance, and cannot block fire for a long time, making it difficult to meet the time requirements for emergency response. Furthermore, in one embodiment of the present invention, the fireproof board 9 is made of calcium silicate fiberboard. Calcium silicate fiberboard has excellent fireproof and heat insulation performance, which can effectively improve the fireproof barrier effect of the fireproof board 9, prolong the time it takes for fire to penetrate the shed 41, and buy sufficient time for staff to carry out emergency response work, thus better protecting the safety of the civil defense basement and surrounding vehicles.

[0029] The overall operating principle of this air-raid shelter with a new energy vehicle self-ignition isolation structure is as follows: The inner frame 1 provides the installation foundation for each component. The flame sensor 5 monitors the interior of the air-raid shelter in real time. When a new energy vehicle is detected to be spontaneously combusting and the location of the fire is identified, a signal is sent to the first linear drive mechanism 2 and the second linear drive mechanism 3. In the first linear drive mechanism 2, the first drive motor 22 drives the first lead screw 23 to rotate, which drives the first slide table 25 to slide along the first slide rail 24 through the first nut 26, thereby driving the second linear drive mechanism 3 and the telescopic isolation shed 4 to move in the left and right directions to the lateral position corresponding to the fire point. Subsequently, in the second linear drive mechanism 3, the second drive motor 34 drives the second lead screw 35 to rotate, which drives the second slide table 37 to slide along the second slide rail 36 through the second nut 38, thereby driving the last shed body 412 to move. The adjacent shed bodies 41 slide and unfold relative to each other through the cooperation of the first guide rail 61 and the second guide rail 62. The first limit block 63 and the second limit block 64 limit the maximum unfolding stroke to prevent the shed body 41 from detaching. After the telescopic isolation canopy 4 is deployed, the fireproof board 9 made of calcium silicate fiberboard on the inner side plays a fireproof barrier role. At the same time, the connecting rod 7 reduces the heat transfer to the drive mechanism, and the reinforcing rib 8 ensures the stability of the connecting structure 6, thereby achieving precise isolation of the spontaneously combusting vehicle and improving the impact of fire spread.
