Description

Technical Field

[0001] This invention belongs to the field of automotive technology, and specifically relates to an automatic lifting, waterproof and fireproof dual-purpose device for new energy vehicles used in underground parking garages. Background Technology

[0002] With the increasing ownership and use of new energy vehicles, issues related to new energy vehicles in my country have received growing attention in recent years. Currently, the safety of new energy vehicles remains a major concern for society, with spontaneous combustion and the spread of fire while parked being particularly prominent. When a new energy vehicle is burning, the high temperature of the battery can easily release oxygen, intensifying the fire, and water short-circuiting the electrical circuits can further amplify the flames, making it difficult to extinguish fires using automatic sprinkler systems or manual water-based firefighting methods.

[0003] Isolating the burning vehicle and creating a immersion tank for cooling and oxygen deprivation is the preferred method for controlling the fire. Existing garage fire isolation devices either only isolate the burning vehicle or the methods for creating a fireproof immersion tank are overly complex and costly. If a single new energy vehicle is burning, it is difficult to simultaneously isolate and extinguish the fire, further escalating the fire and causing severe damage. Furthermore, if the underground garage experiences severe flooding, rainwater will soak the vehicles, and new energy vehicles in the underground garage are also prone to water ingress, causing short circuits and further damage. Summary of the Invention

[0004] This invention provides an automatic lifting, waterproof, and fireproof dual-purpose device for new energy vehicles used in underground parking garages. Its main function is to solve problems related to fire isolation, fire extinguishing, and waterproofing for new energy vehicles in underground parking garages. Furthermore, through a novel fire-fighting box formation method, the space occupied by the equipment is significantly reduced.

[0005] To achieve the objectives of this invention, the present invention provides an automatic lifting, waterproof, and fireproof dual-purpose device for new energy vehicles, comprising a traction rope box, a traction rope, a slide rail, a pulley assembly, a fireproof and waterproof composite tent, a vehicle platform, and a storage box.

[0006] The slide rail is set horizontally, with one end connected to the traction rope box. The pulley assembly is movably set on the slide rail. The pulley assembly includes a fixed pulley, which is used to change the direction of the traction rope.

[0007] The traction rope passes out of the traction rope box, through the fixed pulley, and then into the fireproof and waterproof composite tent edge sealing area located below the traction rope box.

[0008] The vehicle platform is located above the storage box, and there is a gap between the vehicle platform and the storage box. When the device is in standby mode, the fireproof and waterproof composite tent is stored in the storage box.

[0009] During operation, the fireproof and waterproof composite tent is pulled away from the storage box by the traction rope through the gap and gradually rises, so that the fireproof and waterproof composite tent gradually unfolds in the vertical direction, so that the fireproof and waterproof composite tent and the vehicle platform form a box structure. The traction rope drives the pulley assembly to move along the slide rail towards the traction rope box, so that the opening of the box structure is smaller than the bottom of the box. When liquid is filled into the box structure, it can form an immersion tank to extinguish the fire on the vehicle.

[0010] The traction rope is driven and changes direction via a fixed pulley, causing the outer rope of the box to shorten and tighten, and rise. As the traction rope rises, it drives the fireproof and waterproof composite tent below to unfold longitudinally. During the ascent, the tension of the traction rope generates a thrust on the pulley assembly, which in turn drives the roller device of the pulley assembly to roll towards the traction rope box, causing the entire pulley assembly to move horizontally towards the traction rope box. Throughout the ascent of the traction rope, the pulley assembly slides towards the traction rope box, allowing the fireproof and waterproof composite tent to form a drawstring opening as it rises, preventing the spread of fire. Furthermore, it forms a fire box with the vehicle platform to facilitate immersion fire suppression.

[0011] Furthermore, it also includes a drive mechanism connected to the traction coil to drive the scaling of the traction coil.

[0012] Furthermore, during operation, the traction rope box and slide rail are fixed to the ceiling of the parking lot via expansion bolts.

[0013] Furthermore, the traction rope box is equipped with a triggering mechanism. The device is activated actively or by being triggered by the triggering mechanism, which controls the traction rope to rise through the drive mechanism and moves the pulley assembly toward the traction rope box.

[0014] Furthermore, the triggering mechanism is a temperature control switch. When the vehicle catches fire, the temperature of the upper part of the vehicle rises, triggering the temperature control switch.

[0015] Furthermore, the drive mechanism is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. When the triggering mechanism is triggered, the drive mechanism starts and drives the traction rope to rise.

[0016] Furthermore, the fireproof and waterproof composite tent includes a first thin-film waterproof layer, a fireproof layer, and a second thin-film waterproof layer arranged sequentially. The three layers of the tent are tightly bonded together and can be sealed at the edges.

[0017] Furthermore, the fireproof and waterproof composite tent is connected to the storage box wall using waterproof adhesive and other methods to ensure a seal and prevent it from falling off.

[0018] Furthermore, the upper end of the fireproof and waterproof composite tent is turned outwards a short distance (edge ​​sealing) to wrap the upper traction rope. Waterproof adhesive is applied to the upper edge to ensure a tight bond between the edge and the upper part of the fireproof and waterproof composite tent.

[0019] Furthermore, the edge of the vehicle carrier platform is flush with the edge of the storage box in the vertical direction. The storage box has a support structure for supporting the vehicle carrier platform, and there is a gap between the lower edge of the vehicle carrier platform and the outer wall of the storage box. The support structure is used to increase the height of the vehicle carrier platform, creating a certain space to accommodate the fireproof and waterproof composite tent.

[0020] Furthermore, a storage motor is installed on the storage box. One side of the fireproof and waterproof composite tent is fixed inside the storage box. The fireproof and waterproof composite tent can pass through the gap between the vehicle platform and the storage box and contact the rotating output end of the storage motor. When the fireproof and waterproof composite tent is retracted, the reel is released, pulling the reel down, and at the same time, the storage motor starts, retracting the fireproof and waterproof composite tent into the storage box.

[0021] Furthermore, the storage box is also equipped with a drain valve.

[0022] Furthermore, the top surface of the storage box is a vehicle platform, and there is a gap between the storage box wall and the vehicle platform to allow the towing rope and the fireproof and waterproof composite tent to pass through.

[0023] Furthermore, storage motors are installed at the bottom of all four edges of the vehicle platform. These motors are used in the recycling process of the fireproof and waterproof composite tent.

[0024] Furthermore, the receiving motor is a pneumatic cylinder or a hydraulic cylinder.

[0025] Furthermore, the vehicle platform and the supporting structure are made of steel and are connected by welding. The storage box is welded to the supporting structure.

[0026] Furthermore, the storage box can be connected to the underground parking lot floor using expansion bolts to ensure its stability.

[0027] Furthermore, it also includes an inclined ramp, which is hinged to the end of the vehicle platform. When the entire device is in standby mode, the inclined ramp is used to connect the ground and the vehicle platform. When the fireproof and waterproof composite tent is raised, the inclined ramp rotates under the action of the fireproof and waterproof composite tent.

[0028] The fireproof and waterproof composite tent is folded and placed in the storage box, with the inclined ramp close to the ground, allowing vehicles to park on the ramp platform. When the device is activated, the fireproof and waterproof composite tent unfolds and rises with the traction rope, causing the inclined ramp to rotate. When the device is no longer in use and is being recycled, the fireproof and waterproof composite tent is retracted into the storage box by the storage motor, and the ramp returns to its original position.

[0029] Furthermore, the inclined ramp is a steel structure with a triangular cross-section, located at the front of the parking space. When a vehicle reverses, it ascends onto the vehicle platform via the inclined ramp. The inclined ramp and the vehicle platform are connected by hinges. When the fireproof and waterproof composite tent rises, the upper edge of the tent contacts the inclined ramp, and the force of the rising tent causes the inclined ramp to rotate along the hinge axis. When the tent descends, it causes the inclined ramp to rotate back to its original position.

[0030] Furthermore, there are four slide rails, arranged in an X shape, located at four different positions in the traction rope box. Each slide rail is equipped with a corresponding pulley assembly. The two slide rails on the same side are located at the front end of the parking space and are defined as the front slide rails. The other two are located at the rear end of the parking space and are defined as the rear slide rails.

[0031] There are two traction ropes, defined as a front traction rope and a rear traction rope. The front traction rope passes through two fixed pulleys along the two front slide rails and is then threaded into the edging of the fireproof and waterproof composite tent. The rear traction rope passes through two corresponding fixed pulleys along the two rear slide rails and is then threaded into the edging of the fireproof and waterproof composite tent. The front and rear traction ropes are threaded in opposite directions within the fireproof and waterproof composite tent. When the four pulley combinations on each slide rail move towards the traction rope box, the opening of the fireproof and waterproof composite tent can be closed.

[0032] The two interlocking traction ropes at the bottom are wrapped inside the fireproof and waterproof composite tent. The middle of the front traction rope crosses the middle of the rear traction rope, forming an "X" shape, and passes through pre-drilled holes at the four corners of the fireproof and waterproof composite tent. During operation, the two ropes retract in opposite directions.

[0033] Compared with the prior art, the present invention can achieve at least the following beneficial effects:

[0034] (1) Traditional automatic lifting fireproof multi-level parking garages and fireproof barrier devices have the characteristics of complicated installation steps, large space occupation, poor sealing of the fire box, and complicated device start-up process. The main device of the present invention is on the parking lot ground, which is more convenient to install. Only the traction rope box and pulley combination need to be installed on the top of the underground parking lot with expansion bolts. The start-up process of this device is to drive the fireproof and waterproof composite tent to rise and retract through a simple traction rope process. Its movement process is similar to that of a bag, making the operation simpler, more efficient, and easier to maintain.

[0035] (2) Without affecting the use of the parking space, the present invention utilizes the ground space of the parking space for storage, while meeting the net height of the parking space. At the same time, the vehicle platform can be raised to prevent minor water accumulation on the vehicle wall in the underground parking lot, protect the vehicle chassis, and improve the parking quality of the vehicle.

[0036] (3) In addition to fire prevention and isolation and immersion fire extinguishing for fires in new energy vehicles, this invention can also be used in the case of flooding in underground parking lots during rainstorms. The fireproof and waterproof composite tent rises to form a waterproof box, which can prevent vehicles from being submerged in the underground garage during flooding.

[0037] (4) The fire box formed by the present invention can be configured as a truncated quadrangular shape with a tapered top. Compared with the traditional cubic fire box, less water is needed to reach the same water level, allowing the fire box to be formed faster and saving water. Furthermore, the fireproof and waterproof composite tent, in contact with the burning part of the vehicle, helps to isolate the locally burning components. The tapered top of the fireproof and waterproof composite tent further prevents the fire from spreading to surrounding vehicles, effectively isolating the fire.

[0038] (5) The fireproof and waterproof composite tent of the present invention has a flexible material main structure and a traction rope as the auxiliary operating structure. Compared with fireproof roller shutters and other fireproof devices, it saves weight and space, and saves more space. The bottom of the fireproof and waterproof composite tent of the present invention can be tightly bonded to the storage box by means of waterproof glue, etc., and the four sides of the fireproof and waterproof composite tent are integrated as a whole, which has better sealing and avoids the spread of fire through gaps and the leakage of fire box.

Detailed Implementation

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] like Figure 1 As shown, the present invention discloses an automatic car lifting waterproof and fireproof dual-purpose device for use in underground garages, including a traction rope box 1, a pulley assembly 2, a traction rope 3, a fireproof and waterproof composite enclosure 4, a storage box 5, a car carrier 6, and a slide rail 10.

[0056] like Figure 2 As shown, during use, both the traction rope box 1 and the slide rail 10 are connected to the top of the parking lot 8 via expansion bolts 7.

[0057] The slide rail 10 is horizontally arranged, with one end fixedly connected to the traction rope box 1. The pulley assembly 2 is arranged on the slide rail 10 and can move along the slide rail 10. In some embodiments of the present invention, the pulley assembly 2 includes a roller device 16 and a fixed pulley 17. The rollers in the roller device 16 are rotatably arranged on the slide rail 10, and the fixed pulley 17 is connected to the roller device 16. The fixed pulley 17 is used to adjust the direction of the traction rope 3. The roller device 16 can roll on the upper slide rail 10, so that the entire pulley assembly 2 can slide horizontally along the direction of the slide rail 10.

[0058] A drive mechanism 9 is installed inside the traction rope box 1. The traction rope 3 is connected to the drive mechanism 9 inside the traction rope box 1. The traction rope 3 passes through the four corners of the traction rope box 1, is located below the slide rail 10, and is parallel to the slide rail 10. Figure 3 As shown, the traction rope 3 passes through the upper part of the fixed pulley 17 and changes direction through the fixed pulley 17. When the drive mechanism 9 is running, the traction rope outside the box retracts and tightens, and changes the direction of movement of the traction rope 3 through the fixed pulley 17, changing from horizontal movement to upward movement. During the upward movement of the traction rope 3, due to the tension, a thrust is generated on the pulley assembly 2, which in turn drives the roller device 16 to roll towards the traction rope box 1, so that the pulley assembly 2 as a whole moves horizontally towards the traction rope box.

[0059] The traction rope box contains a drive device for controlling the slide rail, ensuring that the roller device 16 on the pulley assembly 2 at the four corners of the device can roll on the slide rail 10 when the device is running.

[0060] In some embodiments of the present invention, the traction rope 3 is a steel wire rope.

[0061] The traction rope box 1 is equipped with a triggering mechanism.

[0062] When the device is actively started or the triggering mechanism is triggered, the drive mechanism 9 works, and the traction rope 3 is wound by the drive mechanism 9; the traction rope 3 is wound around the rotating output end of the drive mechanism 9, and is wound and retracted by the rotation of the drive mechanism 9.

[0063] In some embodiments of the present invention, the drive mechanism 9 includes a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0064] In some embodiments of the present invention, the triggering mechanism is a temperature control switch.

[0065] In some embodiments of the present invention, the traction rope box 1 is also provided with an automatic sprinkler device.

[0066] There are four slide rails 10, which are arranged in an X shape and located at four different positions in the traction rope box 1. Each slide rail 10 is equipped with the pulley assembly 2. Two slide rails 10 located on the same side are located at the front of the parking space and are defined as the front slide rails. The other two are located at the rear of the parking space and are defined as the rear slide rails.

[0067] There are two traction ropes 3 in total. One traction rope 3 has its two ends passing through the two fixed pulleys 17 at the front of the parking space, and the other traction rope 3 has its two ends passing through the two fixed pulleys 17 at the rear of the parking space. The ends of both traction ropes 3 are ultimately connected to the drive mechanism 9 inside the traction rope box 1. The middle section of the traction rope 3 passing through the two fixed pulleys 17 at the front of the parking space is closer to the rear side of the parking space, and the middle section of the traction rope 3 passing through the two fixed pulleys 17 at the rear of the parking space is closer to the front side of the parking space. The two traction ropes 3 form an "X" shape at the corresponding side position of the parking space, and are threaded inside the edging of the fireproof and waterproof composite enclosure 4. During operation, the two traction ropes 3 retract in opposite directions. In detail, as shown... Figure 4 As shown, the fixed pulleys 17 at points A and B are located at the front end of the parking space, and the fixed pulleys 17 at points C and D are located at the rear end of the parking space. The steel wire rope passing through the two fixed pulleys 17 at the front end of the parking space is defined as the front traction rope, and the other steel wire rope is defined as the rear traction rope. The two ends of the front traction rope pass through the fixed pulleys 17 at points A and B respectively. The front traction rope located between the two fixed pulleys 17 is wound around the edge of the fireproof and waterproof composite tent 4 in a clockwise direction. The two ends of the rear traction rope pass through the fixed pulleys 17 at points C and D respectively. The rear traction rope located between the two fixed pulleys 17 is wound around the edge of the fireproof and waterproof composite tent in a counterclockwise direction.

[0068] When the drive mechanism 9 is activated, the two traction ropes 3 retract. Figure 5 As shown, the fireproof and waterproof composite tent 4 has two towing ropes 3 wrapped around its rim, with the towing ropes 3 emerging from the four corners of the tent 4. When the towing ropes 3 rise and retract, the middle of the front towing rope retracts towards the front of the parking space, and the middle of the rear towing rope retracts towards the rear of the parking space. The portions of the two towing ropes 3 wrapped by the fireproof and waterproof composite tent 4 retract in opposite directions, thus tightening the upper part of the fireproof and waterproof composite tent 4 and forming a bag-shaped rim.

[0069] After the fireproof and waterproof composite tent 4 is raised and fully retracted, it takes the shape of a truncated pyramid, smaller at the top and larger at the bottom. Figure 12 As shown. Adding water to the fireproof and waterproof composite tent 4 can create a fire extinguisher box, which can be used to extinguish fires by soaking burning vehicles.

[0070] In some embodiments of the present invention, such as Figure 5As shown, the upper edge of the fireproof and waterproof composite tent 4 is wrapped with two strands of traction ropes to form the upper edge 11 of the fireproof and waterproof composite tent. The lower end is tightly connected to the wall of the storage box to ensure that it does not leak water.

[0071] In some embodiments of the present invention, the outward upper edge of the fireproof and waterproof composite tent 4 is bonded to the fireproof and waterproof composite tent 4 by waterproof adhesive.

[0072] In some embodiments of the present invention, the fireproof and waterproof composite tent 4 is connected on all four sides, with no closure on the top and bottom sides. The upper edge of the composite tent is turned outward to wrap two traction ropes. Openings are made at the four corners of the fireproof and waterproof composite tent to ensure that the ends of the traction ropes at the four corners pass normally through the pulleys and are connected to the drive mechanism, and to ensure that the ropes can operate normally.

[0073] In some embodiments of the present invention, such as Figure 6 As shown, the fireproof and waterproof composite tent 4 has a three-layer structure, including a first thin-film waterproof layer 41, a fireproof layer 42, and a second thin-film waterproof layer 43 arranged sequentially.

[0074] like Figure 7 As shown, the vehicle carrier plate 6 is located above the storage box 5, and the edge of the vehicle carrier plate 6 is flush with the edge of the storage box 5 in the direction perpendicular to the ground. Figure 7 As shown, the storage box 5 has a raised support structure 15 inside, which is higher than the outer wall of the storage box 5. The support structure is used to support the vehicle platform 6. There is a gap between the lower edge of the vehicle platform 6 and the outer wall of the storage box 5 to ensure that the towing rope 3 and the fireproof and waterproof composite tent 4 can pass smoothly through the gap. When the device is in standby mode, the fireproof and waterproof composite tent 4 is stored in the internal space of the storage box 5.

[0075] Storage motors 12 are installed on the four walls of the storage box 5. The storage motors 12 are fixed to the walls of the storage box 5 via cantilever arms, such as... Figure 7 As shown. The lower edge of the fireproof and waterproof composite tent 4 is bonded to the storage box 5 with waterproof adhesive, ensuring good sealing. The fireproof and waterproof composite tent 4 is stored in the space of the storage box 4. The upper part of the fireproof and waterproof composite tent 4 passes through the gap between the storage motor 12 and the vehicle platform 6, and the fireproof and waterproof composite tent 4 contacts the rotating output end of the storage motor 12, and extends out from the gap between the vehicle platform 6 and the storage box 5.

[0076] When the device is in standby mode or the fireproof and waterproof composite tent is raised, the storage motor 12 is in standby mode; when the fireproof and waterproof composite tent 4 is lowered, the storage motor 12 is started, and the fireproof and waterproof composite tent 4 is recovered by the contact friction between the rotating output end of the storage motor 12 and the fireproof and waterproof composite tent 4, thereby driving the fireproof and waterproof composite tent 4 to descend and be recovered into the storage box 5.

[0077] In some embodiments of the present invention, the storage box 5 is provided with a drain valve 14, which allows the device to drain the water used for fire extinguishing inside the fireproof and waterproof composite tent 4.

[0078] In some embodiments of the present invention, the length and width of the storage box 5 are greater than the parking space, and the storage box 5 is positioned above the ground 13 to ensure sufficient space for placing the fireproof and waterproof composite tent and the motor 12.

[0079] In some embodiments of the present invention, the front end of the storage box has an inclined ramp 18, which is hinged to the vehicle platform via a hinge. The rigid ramp has a right-angled triangular cross-section and can rotate normally via the hinge.

[0080] In some embodiments of the present invention, the vehicle platform 6 is a rigid lightweight steel frame plate.

[0081] like Figure 8 As shown, a rigid inclined ramp 18 is provided at the front end of the vehicle platform 6. The inclined ramp 18 is connected to the vehicle platform 6 via a hinge 19, and the hinge 19 can rotate freely. When the entire device is in standby mode, the bottom surface of the inclined ramp 18 is flat. At this time, the inclined surface of the ramp 18 connects the ground and the plane of the vehicle platform 6, allowing vehicles to smoothly park on the vehicle platform 6 via the ramp. Figure 9 As shown, when the fireproof and waterproof composite tent 4 rises, it comes into contact with the inclined ramp 18. Due to its upward force, the inclined ramp 18 can rotate counterclockwise along the hinge 19, thus preventing it from obstructing the rise of the fireproof and waterproof composite tent 4. When the fireproof and waterproof composite tent 4 descends or is retracted, the inclined ramp 18, driven by the fireproof and waterproof composite tent 4 and under the action of gravity, will rotate clockwise along the hinge 19 until it is placed flat on the ground.

[0082] The present invention discloses an automatic lifting waterproof and fireproof dual-purpose device for underground garages, which includes five operating states: standby roll storage, full load of vehicle platform, tent raising, tent retraction, and tent lowering.

[0083] like Figure 10 As shown, the device is in standby mode at this time. The vehicle platform 6 is slightly higher than the underground garage floor, the inclined ramp 18 is placed flat, and the fireproof and waterproof composite tent 4 is stored in the storage box 5 located below the vehicle platform 6. The traction ropes 3 at the four corners of the vehicle platform 6 are perpendicular to the ground and the direction of the traction ropes is changed by the fixed pulley 17.

[0084] like Figure 11As shown, the device is in the rising state: the drive mechanism 9 inside the traction rope box 1 is activated, driving the traction rope 3, which shortens and retracts, causing the fireproof and waterproof composite tent 4 connected to it to rise. As the fireproof and waterproof composite tent 4 rises, it comes into contact with the inclined ramp 18, and due to its upward force, the inclined ramp 18 rotates counterclockwise along the hinge 19.

[0085] like Figure 12 As shown, the device is in the retracted state: the fixed pulley 17 slides towards the traction rope box 1 following the upward trend of the traction rope 3, the drive mechanism 9 inside the traction rope box 1 continues to operate, the traction rope 3 further retracts and rises, and the fireproof and waterproof composite tent 4 rises further; when the fireproof and waterproof composite tent 4 rises to its limit height, the traction rope 3 further retracts and rises, and the upper end of the fireproof and waterproof composite tent 4 is closed, forming a four-sided frustum-shaped fire box.

[0086] When the device is in its retracted state, the interior of the fireproof and waterproof composite tent 4 can be filled with water to form a soaking tank, with the soaking height exceeding the height of the vehicle, ensuring the burning vehicle is completely submerged. After soaking, the water in the fire extinguisher box can be drained through the drain valve 14. Forming a truncated pyramid shape and adding water can quickly create a soaking tank for rapid fire extinguishing of burning vehicles.

[0087] like Figure 14 As shown, the device is in the descending state. The drive mechanism 9 inside the traction rope box 1 releases the traction rope 3, and the traction rope 3 extends outward. The fireproof and waterproof composite tent 4 descends naturally due to gravity. The storage motor 12 starts, retracting the fireproof and waterproof composite tent 4 into the storage box 5.

[0088] In addition to being applied to situations where new energy vehicles spontaneously combust and require isolation and immersion extinguishing, the device provided in the foregoing embodiments of the present invention can also be used to prevent flooding of new energy vehicles in basements.

[0089] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
