Description

Technical Field

[0001] The present invention relates to the technical field of fire safety for new energy vehicles, and in particular to a portable fire safety device for new energy vehicles. Background Art

[0002] The rapid popularization of new energy vehicles has not only brought benefits of environmental protection and energy structure transformation, but also brought with it a series of new challenges, especially in terms of safety. Among them, the safety hazards of lithium batteries have become one of the important issues that cannot be ignored.

[0003] Although lithium batteries have the advantages of high energy density and long life, their inherent chemical properties also determine that they may cause serious safety accidents under certain conditions. For example, in a traffic accident or improper charging process, lithium batteries may suffer physical damage or overheat, which may lead to internal short circuits and eventually fire or explosion. As the battery performance gradually decreases over time, this risk will also increase accordingly. Once a lithium battery catches fire, due to its violent internal chemical reaction, the fire spreads very quickly. Conventional fire-fighting methods are often difficult to control the fire in a short period of time, which brings great difficulties to rescue work.

[0004] Especially in urban environments, due to the shortage of parking resources, new energy vehicles are often densely parked in underground garages. This layout amplifies the risk of a single vehicle catching fire. Once a vehicle catches fire, the high temperature and flames can quickly spread to neighboring vehicles, forming a "fire in the camp" situation. In this case, due to the space limitations of the underground garage, traditional fire trucks are often unable to enter the scene in time for effective rescue, further exacerbating the severity of the accident.

[0005] In addition, underground garages are usually designed to accommodate daily vehicle traffic, and no special arrangements are made for the passage of large firefighting equipment. This means that in an emergency, firefighters can only rely on portable firefighting equipment for rescue, which is not only inefficient but also has limited effectiveness when facing lithium battery fires. If an accident occurs during peak hours or in traffic congestion, the response time of firefighters will be further extended, increasing the potential losses caused by the accident. Summary of the invention

[0006] In response to the above-mentioned safety hazards of new energy vehicles, the present invention provides a portable new energy vehicle fire safety device, aiming to provide a portable, fast fire extinguishing device to extinguish the burning new energy vehicle and prevent adjacent vehicles from being implicated.

[0007] The solution adopted by the present invention to solve its technical problems is: a portable new energy automobile fire safety device, including a front door and a rear door, folding side doors are hinged on both sides of the front door, the folding side doors are composed of multiple door panels hinged in sequence, a folding roof is installed on the front door and the rear door, and casters are fixed below the front door, the rear door and the folding side door. Exhaust holes and sprinkler heads are arranged on the folding roof, and water pipe joints are arranged on the front door and the rear door. The water pipe joints are connected to corresponding sprinkler heads through flexible water pipes. When the folding side doors and the folding roof are unfolded, the folding side doors are fixed to the rear door through buckles, so that the front door, the rear door, the folding side doors and the folding roof form a closed rectangular box body to wrap the car.

[0008] Furthermore, the front door and the rear door both adopt angle iron welded rectangular frames, and the angle iron welded rectangular frames are covered with metal plates, and the metal plates are made of high temperature resistant and fireproof material.

[0009] Furthermore, the folding ceiling includes a top plate 1 and a top plate 2, a track is provided between the top plate 1 and the top plate 2, and the top plate 1 and the top plate 2 are slidably mounted between the track, and protruding carrier plates are respectively provided at the top ends of the front door and the rear door, and strip sliding holes 1 are provided on both side surfaces of the top plate 1, and an insertion rod is provided on the side of the carrier plate facing the strip sliding hole 1, and the insertion rod is mounted in the strip sliding hole 1.

[0010] Furthermore, a hook plate is provided on the outer side of the top plate 2. When the top plate 2 and the top plate 1 are folded, the hook plate hooks the frame of the top plate 1 to fix the folded top plate 1 and the top plate 2.

[0011] Furthermore, a pulley is installed on the outer frame of the folding roof, and a track is set on the upper frame of the folding side door. When the folding side door is unfolded and flattened, the tracks on the upper frame of the folding side door are combined into a straight track, and the pulley installed on the folding roof can slide along the track.

[0012] Furthermore, the carrier plate is an L-shaped plate, one end of the L-shaped plate is welded to the two ends of the upper frames of the front and rear doors, and the other end of the L-shaped plate extends upward and fixes the insertion rod.

[0013] Furthermore, it also includes a mobile sprinkler head, which includes a hard water pipe and a sprinkler head. The sprinkler head is installed at the end of the hard water pipe, and the other end of the hard water pipe is connected to a fire water source. The front and rear doors are provided with movable sprinkler head sockets, and the movable sprinkler head sockets are located in the lower half of the front and rear doors. The mobile sprinkler is inserted into the bottom of the car through the movable sprinkler head socket.

[0014] Furthermore, the exhaust holes are arranged on the top plate 1, the spray heads are arranged on the top plate 2, and the number of the spray heads installed on each top plate 2 is greater than or equal to 2.

[0015] Furthermore, the casters are universal wheels, and handles are provided on the front and rear doors.

[0016] Furthermore, an outer frame is arranged on the outer side of the rear door, and the outer frame extends toward the front door. After the folding side door is unfolded, the frame of the folding side door facing the rear door is inserted into the outer frame of the rear door.

[0017] Beneficial effects of the present invention: The advantages of the portable new energy vehicle fire safety equipment of the present invention are that the equipment is foldable as a whole, and its volume is reduced after folding, which is convenient for transportation and carrying by fire trucks, and is also convenient for storage and use in parking lots, especially underground parking lots; it can be quickly arranged and can be assembled by ordinary people within three minutes, and can promptly prevent the fire from spreading to adjacent vehicles to avoid further losses, especially in underground parking lots that fire trucks cannot enter; the entire equipment is made of stainless steel or fireproof material, which can effectively prevent the spread of fire; it is highly efficient, requires less water for spraying, and can extinguish fires and cool down in a long-lasting and efficient manner. At the same time, the movable spray at the bottom can extinguish fires and cool down specific parts such as the bottom battery.

[0018] Reduce the spread of toxic smoke during the combustion process. The top sprinkler head and the bottom movable sprinkler head can extinguish the fire and cool the burning vehicle for a long time in all directions. The sprayed water mist can filter the harmful gases from the combustion and reduce the harmful gases, especially in the underground garage, to prevent casualties and gain sufficient time for the evacuation of irrelevant personnel. If the exhaust hole can be connected to the fire smoke duct, the effect will be better.

[0019] The folding roof adopts a slide to form a folding structure, which can be quickly unfolded in a limited height space, avoiding the problem that the traditional flip-type unfolding structure requires a large space. It can be widely used in spaces with limited height such as underground garages.

[0020] Using water pressure to assist the deployment of the folding side doors can save energy for rescue workers, increase the deployment speed, and spray water simultaneously during the deployment process to prevent flames from burning rescue workers during the deployment process.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below.

[0024] Example 1: The present invention provides a new energy vehicle fire safety device, aiming to provide a portable, fast fire extinguishing device. Ordinary people can complete the installation of the equipment within 3 minutes, extinguish the burning new energy vehicle, and prevent adjacent vehicles from being affected. It is particularly suitable for parking lots where vehicles are parked in a concentrated manner, especially underground garages that fire trucks cannot enter.

[0025] like Figure 1 As shown, the fire safety equipment includes a front door 1 and a rear door 3, both of which are made of angle iron welded rectangular frames, and a metal plate is coated on the rectangular frames welded by the angle irons. The metal plate can be made of stainless steel or other high temperature resistant and fireproof materials.

[0026] Casters 9 are installed below the rectangular frames of the front and rear doors 3. The casters 9 are universal wheels. Handles are also provided on the front and rear doors 3. The fire safety device of the present invention can be easily pushed to a desired position through the handles and casters 9.

[0027] like Figure 1 and Figure 2As shown, the front door 1 is hinged with folding side doors 2 on both sides, and the folding side doors 2 are unfolded to form side curtains, and the unfolded side curtains are perpendicular to the front door 1. The folding side door 2 is composed of multiple rectangular plates hinged in sequence. The rectangular plates can also be made by welding angle iron frames and iron plates as plate surfaces.

[0028] The foldable roof comprises a front foldable roof 5 hinged on the front door and a rear foldable roof 6 hinged on the rear door. The foldable roofs each comprise a top plate 1 and a top plate 2, a track is arranged between the top plate 1 and the top plate 2, and the top plate 1 and the top plate 2 can be slid and unfolded through the track.

[0029] Specific as Figure 3 As shown, a front folding roof 5 is hinged on the upper frame of the front door 1. Figure 6 As shown, a rear folding roof 6 is hinged on the upper frame of the rear door 3 .

[0030] It is necessary to explain that the portable new energy vehicle fire safety equipment provided by the present invention is mainly used in underground garages and other places with a large number of vehicles. The fire safety equipment can avoid affecting surrounding vehicles and prevent the fire from spreading. In addition, due to the limited height of the garage space, the ordinary hinged folding roof needs to be flipped over significantly. In this case, the flip height of the roof plus the height of the front and rear doors themselves can easily exceed the height of the garage, affecting the rapid arrangement of fire isolation facilities. Therefore, the present invention provides a portable new energy vehicle fire safety equipment. Figure 3 and Figure 4 The folding roof structure shown.

[0031] The folding ceiling installed on the front and rear doors of the present invention has the same structure and the same installation method. This embodiment uses the front door as an example to illustrate the folding ceiling.

[0032] A carrier plate is fixed at both ends of the top of the front door. The carrier plate is an L-shaped plate 101. The horizontal section of the L-shaped plate 101 is welded to the side frame of the front door, and its vertical section extends upward to the top of the front door. A plug rod 15 is fixed on the inner side of the vertical section of the L-shaped plate 101.

[0033] The side frame of the front top plate 1 501 is provided with a strip-shaped sliding hole 1 511, and the front top plate 1 is installed in the middle of the two side carriers, and the insertion rods on the carriers are inserted into the strip-shaped sliding hole 1 511. When in use, the lower frame of the front top plate 1 is pushed from the bottom, and the front top plate 1 can slide on the insertion rods, thereby turning over to the top of the front door and the folding side door.

[0034] The side of the front top plate 1 501 or the front top plate 2 502 is provided with a strip-shaped sliding hole 2 512, and correspondingly, a clamping plate 521 is respectively provided on both sides of the lower end or the upper end of the front top plate 2 502 or the front top plate 1 501. The side of the clamping plate facing the top plate is provided with an insertion rod that can be inserted into the strip-shaped sliding hole 2 512, so that the front top plate 1 501 and the front top plate 2 502 can slide and unfold through the track formed by the insertion rod and the strip-shaped sliding hole 2 512.

[0035] like Figure 4 As shown, parallel strip sliding holes 1 511 and strip sliding holes 2 512 are arranged on both side frames of the front top plate 1 501. The strip sliding hole 1 511 is close to the front door, and the insertion rod on the top carrier plate of the front door is inserted into the strip sliding hole 1 511; the strip sliding hole 2 512 is close to the front top plate 2, and the clamping plates 521 are fixed on both sides of the lower end of the front top plate 2. The clamping plates are arranged with insertion rods on the sides of the strip sliding hole 2 512 and inserted into the strip sliding hole 2 512.

[0036] When in use, the front folding roof can be pushed as a whole to slide obliquely along the strip-shaped sliding hole 1 511 to the top of the front door, which can reduce the space required for the folding roof to unfold. At the same time, when the pushing distance exceeds the center of the folding roof, the center of gravity of the folding roof moves to the front door, and the folding roof can be laid on the upper frame of the folding side door under the action of gravity. At this time, the front folding roof can be pushed horizontally to unfold, reducing the height requirement during the unfolding process.

[0037] like Figure 6 As shown, the rear folding roof 6 hinged on the rear door 3 has the same structure as the front folding roof 5, and the description is not repeated here. The difference is that a larger outer frame 301 is provided on the outside of the rear door 3, and the outer frame 301 extends toward the front door 1. The folding side door 2 can be inserted into the outer frame 301 after being unfolded, and the carrier plate (L-shaped plate 101) for installing the rear folding roof 6 is welded on both sides of the outer frame 301.

[0038] A hook plate 10 is arranged on the outer side of the second top plate, and the outer side is the frame away from the front and rear doors after the folding roof is unfolded. When the second top plate is folded with the first top plate, the hook plate 10 can hook the frame of the first top plate to fix the folded first top plate and the second top plate.

[0039] A buckle is provided between the folding side door 2 and the rear door 3. After the folding side door 2 is unfolded and inserted into the rear door 3, the two are fixed by the buckle.

[0040] The specific usage is: the front door 1 and the rear door 3 are respectively moved to the front and rear of the vehicle by casters 9, and the folding side doors on both sides of the front door are pulled to unfold on both sides of the vehicle. The unfolded side door frames are connected and fixed to the rear door by buckles, thereby forming a rectangular enclosure on the outside of the vehicle.

[0041] like Figure 8As shown, the folding roof mounted on the front and rear doors is pushed, and the top plate 1 of the folding roof slides along the insertion rods at both ends of the top of the front and rear doors, so that the folding roof is flipped to the top of the enclosure, and the two side frames of the folding roof are placed on the top of the folding side door. Then, the top plate 2 is pushed to slide along the strip-shaped sliding hole 2 512, so that the folding roof is fully unfolded to cover the top of the vehicle, preventing the fire of the burning vehicle from spreading outward.

[0042] like Figure 5 As shown, in order to make the folding roof slide more easily on the top of the folding side door, pulleys 503 are provided on the side frames of the top plate 1 and the top plate 2 of the folding roof, and tracks 201 are provided on the upper frames of the folding side door 2. During the unfolding process, the pulleys 503 can move along the tracks 201, so that the folding roof can be unfolded more easily.

[0043] like Figure 1 As shown, a plurality of sprinkler heads 8 and exhaust holes 7 are also provided on the front and rear folding ceilings. A water pipe joint 12 is provided on the front and rear doors 3, and the two ends of the water pipe joint 12 are respectively connected to the fire hose and the sprinkler heads 8 on the front and rear folding ceilings, and the water pipe joint 12 is connected to the sprinkler heads 8 through a hose. In this embodiment, the exhaust holes 7 are provided on the front top plate 1 501 and the rear top plate 1 601, and the sprinkler heads 8 are provided on the front top plate 2 502 and the rear top plate 2 602, and at least two sprinkler heads 8 are installed on the front top plate 2 502 and the rear top plate 2 602.

[0044] Furthermore, the front and rear doors 3 are also provided with a movable shower head socket 11, and the movable shower head socket 11 is located at the lower part of the front and rear doors 3. Figure 7 As shown, the portable new energy vehicle fire safety equipment of the present invention further includes a mobile sprinkler head, which includes a hard water pipe 13 and a sprinkler head 14. The sprinkler head 14 is installed at the end of the hard water pipe 13, and the other end of the hard water pipe 13 is connected to a fire water source. The mobile sprinkler head can be inserted under the vehicle chassis through the movable sprinkler head socket 11, so as to spray and extinguish the fire from bottom to top through the sprinkler head 14.

[0045] Generally, the parking space is 6 meters long and 2.5 meters wide in a low-lying parking lot, and the height of the vehicle is less than 1.9 meters. The front door 1 of the portable fire safety equipment for new energy vehicles of the present invention is set to be 2.5 meters wide and 2.2 meters high. The folding side doors 2 on both sides are folded 5 times, each folding is 1.2 meters. The rear door 3 is 2.52 meters long and 2.22 meters high. The front and rear folding roof is composed of two folds (i.e., top plate 1 and top plate 2), which are 1.5 meters long and 2.5 meters wide. If a single new energy vehicle is on fire, the equipment is quickly moved to the front of the vehicle, the rear door 3 is removed, and the folding doors on both sides are unfolded backward to prevent the fire from spreading to the vehicles on both sides. The rear door 3 is buckled, and the folding roof is pushed in from the track 201 above the front and rear doors 3. The front door 1 or the rear door 3 is inserted into the movable sprinkler, and the fire water is connected to the water pipe interface of the front door 1 or the rear door 3 of the equipment, and the fire vehicle in the parking space is sprayed with water in all directions to extinguish the fire and cool it down until the fire is completely extinguished.

[0046] Embodiment 2: In embodiment 1, the folding side door is fully deployed by manpower. In case of vehicle fire, time is precious. Therefore, in order to enable a lighter and faster deployment, the present invention further provides a method of utilizing water pressure to assist the deployment of the folding side door.

[0047] Specific as Fig. 9 As shown, a flexible braided water pipe 15 is installed on the outside of the folding side door. The flexible braided water pipe can be installed on the outside of the folding side through a clamp, and the tail end of the flexible braided water pipe is fixed on the farthest folding side door panel.

[0048] When in use, the flexible braided water pipe 15 is connected to the high-pressure water pipe, and water with a relatively high pressure is flowed into the flexible braided water pipe 15. The flexible braided water pipe 15 swells under the water pressure and generates a straightening force, and the expansion and straightening force of the flexible braided water pipe 15 assists the user to quickly unfold the foldable side door. The flexible braided water pipe 15 can be a fire hose, which can withstand a relatively large pressure, and the water pipe has a high degree of deformation, and can provide a relatively large expansion force to promote the unfolding of the foldable side door.

[0049] A series of water spray outlets may also be provided on the upper frame of the folding side, and the water spray outlets are connected to the flexible braided water pipe 15, so that spray cooling is performed while the folding side door is unfolded to prevent the flame from burning the rescuers.

[0050] Furthermore, two or more parallel flexible braided water pipes 15 may be laid on the upper and lower sides of the outer surface of the folding side surface, so as to increase the expansion force of the flexible braided water pipes 15 when flushed with water and increase the expansion speed of the folding side door.

[0051] Embodiment 3: This embodiment further provides a push rod mechanism for unfolding the folded side, as shown in FIG. Fig.10As shown, the push rod mechanism is installed on the upper or lower frame of the folding side door, and the push rod mechanism is installed between the acute angles of the hinged part of the folding side door. The push rod mechanism includes a cylinder 16, a piston 17 and a push rod shaft 18. A group of pistons 17 are symmetrically installed in the cylinder 16, and each piston 17 is installed with a push rod shaft 18 extending to the outside of the cylinder. The end of the push rod shaft is hinged to the corresponding folding side door panel or the lower frame. A convex shaft can be provided on the folding side door panel or the lower frame, and an axis hole is provided at the end of the push rod shaft. The push rod shaft is hinged to the folding side door panel by being sleeved on the convex shaft through the axis hole.

[0052] A water inlet is provided in the middle of the cylinder for connecting a fire hose or a flexible braided water pipe 15. The water inlet is located between the two pistons. High-pressure water is introduced into the cylinder through the fire hose or the flexible braided water pipe, and the water pressure is used to push the push rod shaft out, thereby pushing the door panels on both sides to unfold. During the process of spraying fire extinguishing, water is continuously supplied to the cylinder, and the thrust of the push rod mechanism can be used to keep the door panels in an unfolded state. When the burning vehicle explodes, the push rod can provide resistance to the unfolding of the door panels to prevent the hinged parts of the door panels from bending and folding.

[0053] Example 4: Fig.11 As shown, the present invention provides three articulation modes, wherein Fig.11 (1) Ordinary hinges are used; Fig.11 (2) adopts the method of installing a chain plate 19 above the door panel of the folding side door for hinge connection, a convex shaft is provided above the door panel, the chain plate 19 is installed between the convex shafts, and a side baffle is also provided between the upper and lower chain plates 19 to cover the gap at the hinged part; further, Fig.11 (3) An auxiliary folding mechanism is also provided in the chain plate hinge structure, and the auxiliary folding mechanism includes a push rod mechanism installed between the acute angles of the hinge part. The push rod mechanism has the same structure as that in Example 3. In order to ensure that the water pressure preferentially pushes the push rod mechanism, a gate valve 20 with a gate plate is fixed on the opposite side of the push rod mechanism, and both ends of the gate valve are respectively connected to flexible braided water pipes.

[0054] A connecting rod 24 is connected to the gate plate 21 of the gate valve, a push plate 23 is fixed to the end of the connecting rod 24 facing the push rod mechanism, the push plate is connected to the side of the push rod mechanism, and the water inlet of the push rod mechanism is connected to the water pipe on the water inlet side of the gate valve.

[0055] In the initial state, the gate valve is closed, and water is passed into the water pipe. The water flow will first enter the push rod mechanism, so that the push rod mechanism drives the door panel to unfold. During the unfolding process, the cylinder of the push rod mechanism approaches the hinge point, thereby pushing the push plate, connecting rod and gate plate connected as a whole to move. A gate plate cavity 22 is provided on the outside of the gate valve, and the pushed gate plate moves into the gate plate cavity to make the gate valve pass through. The water flow is transported along the water pipe to the next hinge point, and then the folded door panels are unfolded in turn.

[0056] Since the acute angles of the hinge are in two directions, the gate valves and the push rod mechanisms are arranged alternately on both sides of the door panel, so perforations can be provided on the door panel so that the water pipe can be connected to the gate valve on the inside or outside.

[0057] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
