[0002] With the popularization of new energy electric vehicles, their fire risks have gradually emerged. Fires in new energy electric vehicles are characterized by fast burning speed, high temperature, and high risk of re-ignition. Traditional fire extinguishing methods often have difficulty effectively controlling the fire. As a common fire extinguishing tool, a fire control blanket can cut off oxygen by covering the fire source to achieve the purpose of extinguishing the fire. However, the traditional fire control blanket has the following problems when in use:

[0003] 1. After being folded, the fire control blanket has a large volume and heavy weight, making it inconvenient to move.

[0004] 2. When unfolding the fire control blanket at the fire scene, usually multiple people are required to cooperate, which is time-consuming and laborious.

[0005] 3. The unfolding speed of the fire control blanket is slow, making it difficult to quickly cover the fire source in the initial stage of the fire, affecting the fire extinguishing efficiency.

[0006] Therefore, there is an urgent need for a fire control blanket device that can be quickly unfolded, is convenient to move, and is easy to operate, so as to improve the efficiency of fire fighting for new energy vehicles. Summary of the Utility Model

[0007] In view of this, the purpose of the utility model is to provide a laying device for a fire control blanket for quickly covering new energy vehicles, and the technical problem to be solved is that the existing fire control blanket has a large volume and heavy weight after being folded, making it inconvenient to move, and when unfolding the fire control blanket at the fire scene, usually multiple people are required to cooperate, which is time-consuming and laborious. In addition, the existing fire control blanket has a slow unfolding speed and is difficult to quickly cover the fire source in the initial stage of the fire, affecting the fire extinguishing efficiency.

[0008] To achieve the above technical purpose, the utility model provides a laying device for a fire control blanket for quickly covering new energy vehicles:

[0009] It includes a box body. The front side of the box body is designed to be open, and a box door for sealing the opening is rotatably connected to the bottom of the front side of the box body. The inner walls of the left and right sides of the box body are jointly rotatably connected with a rotating shaft. A fire control blanket is wound around the outside of the rotating shaft. A clamping slot is opened in the rotating shaft, and one side of the fire control blanket can be embedded into the clamping slot. The inner walls of the left and right sides of the box body are jointly fixed with a cylindrical rod. A cylindrical cylinder is arranged on the outside of the cylindrical rod. The cylindrical cylinder rotates on the outside of the cylindrical rod. A spiral spring is arranged inside the cylindrical cylinder. One side of the spiral spring is fixed to the inner wall of the cylindrical cylinder, and the other side of the spiral spring is fixed to the cylindrical rod. An arc-shaped supporting plate is fixed to the outside of the cylindrical cylinder, and the arc-shaped supporting plate abuts against the fire control blanket.

[0010] Preferably, a groove is formed at the rear end of the bottom of the box body, two bases are fixed in the groove, and rollers are installed at the bottom of the bases.

[0011] Preferably, two screws are fixed to both the inner wall of the top of the groove and the front end of the bottom of the box body. A threaded cylinder is threadedly connected to the outer side of the screw, and a foot pad is fixed to the bottom of the threaded cylinder.

[0012] Preferably, a positioning plate is fixed to one side of the box body, a convex block is fixed to one side of the box door, a positioning hook is slidably connected in the convex block, a positioning hole is formed in the positioning plate, and one end of the positioning hook can be embedded into the positioning hole.

[0013] Preferably, a baffle is fixed to the bottom of the positioning hook, a spring is sleeved on the outer side of the positioning hook, one end of the spring abuts against the baffle, and the other end of the spring abuts against the convex block.

[0014] Preferably, guide disks are fixed to both ends of the rotating shaft extending outside the box body.

[0015] Preferably, the bottom of the threaded cylinder is arranged in a rectangle.

[0016] Preferably, there are four foot pads which are respectively arranged at the four corners close to the bottom of the threaded cylinder.

[0017] Preferably, blocking plates are respectively arranged at the two end parts of the rotating shaft.

[0018] Preferably, a pull rope is arranged at one end of the fire control blanket away from the rotating shaft.

[0019] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0020] 1: Pull the fire control blanket outward so that the fire control blanket drives the rotating shaft to rotate, thereby pulling the fire control blanket out of the box body. At the same time, during the process of pulling out the fire control blanket, the two pull ropes are moved in opposite directions, so that the fire control blanket automatically unfolds during the pulling process. Since the fire control blanket is pre-wound on the rotating shaft, the unfolding process is fast and uniform, and it can quickly cover the fire source to achieve the purpose of extinguishing the fire. 2: During the process of winding up the fire control blanket, the arc-shaped support plate abuts against the fire control blanket, so that the fire control blanket can be tightly wound on the rotating shaft, avoiding the situation of the fire control blanket becoming loose. When the fire control blanket is wound up, the diameter of the formed drum gradually increases. Due to the setting of the coil spring, when the gradually increasing drum formed by the fire control blanket presses against the arc-shaped support plate, it will drive the arc-shaped support plate to rotate. When the arc-shaped support plate rotates, it drives the cylindrical barrel to rotate. When the cylindrical barrel rotates, it compresses the coil spring, so that the arc-shaped support plate can always abut against the fire control blanket. 3: Since two rollers are installed at the rear end of the bottom of the box body, the entire laying device can be towed by tilting the box body backward. And the foot pads installed at the front end of the bottom of the box body and in the grooves make that when the box body is moved to the required position and then placed vertically, the foot pads contact the ground, so that the box body will not move when the fire control blanket is pulled out to cover the fire source.

[0029] The following description is essentially exemplary only and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure.

[0030] Referring to Figures 1 - 6 :

[0031] As an embodiment of the present utility model, there is provided a laying device for a fire control blanket for quickly covering a new energy vehicle, including a box body 1. The front side of the box body 1 is open, and the bottom of the front side of the box body 1 is rotatably connected with a box door 2 for sealing the opening. The inner walls of the left and right sides of the box body 1 (it should be understood that the front side of the box body 1 is provided with a box door 2 as shown in the figure) are jointly rotatably connected with a rotating shaft 3. A fire control blanket 4 is wound around the outer side of the rotating shaft 3. A clamping slot 9 is opened in the rotating shaft 3. One side of the fire control blanket 4 can be embedded into the clamping slot 9. The inner walls of the left and right sides of the box body 1 are jointly fixed with a cylindrical rod 5. A cylindrical barrel 6 is arranged on the outer side of the cylindrical rod 5. The cylindrical barrel 6 rotates on the outer side of the cylindrical rod 5. A coil spring 8 is arranged in the cylindrical barrel 6. One side of the coil spring 8 is fixed to the inner wall of the cylindrical barrel 6, and the other side of the coil spring 8 is fixed to the cylindrical rod 5. An arc-shaped support plate 7 is fixed to the outer side of the cylindrical barrel 6. The arc-shaped support plate 7 abuts against the fire control blanket 4. Both ends of the rotating shaft 3 extending outside the box body 1 are fixed with guide discs 10. It should be understood that the front side, left and right sides of the box body 1 are generally designated. That is, the box body 1 is regarded as a cuboid structure with six rectangular faces. The side where the box door 2 is set can be called the front side (or front side face), and the upper and lower side faces and the left and right side faces are connected to it. As shown in the figure, it is obvious that both ends of the rotating shaft 3 are respectively connected to the inner walls of the left and right sides (or called left and right side faces) of the box body 1.

[0032] It should be noted that a telescopic pull rod is provided on one side of the box body 1. When the fire control blanket 4 is pulled out from the box body 1, pull ropes 23 are fixed at both corners of the side of the fire control blanket 4 that is getting farther and farther away from the rotating shaft 3. During use, only two operators need to hold the two pull ropes 23 on one side of the fire control blanket 4 respectively, and then pull the fire control blanket 4 outwards, so that the fire control blanket 4 drives the rotating shaft 3 to rotate, thereby pulling the fire control blanket 4 out of the box body 1. At the same time, during the process of pulling out the fire control blanket 4, the two pull ropes 23 are moved in a direction away from each other, so that the fire control blanket 4 automatically unfolds during the pulling process. Since the fire control blanket 4 is pre-wound on the rotating shaft 3, the unfolding process is fast and uniform, and it can quickly cover the fire source to achieve the purpose of extinguishing the fire.

[0033] When the fire control blanket 4 needs to be stored, first fold the fire control blanket 4 in half, then embed one side of the fire control blanket 4 into the slot 9, and then rotate the guide disk 10 to drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, the fire control blanket 4 can be wound up. During the winding process of the fire control blanket 4, the arc-shaped support plate 7 abuts against the fire control blanket 4. Due to the abutting effect of the arc-shaped support plate 7, the fire control blanket 4 can be tightly wound on the rotating shaft 3 to prevent the fire control blanket 4 from becoming loose. When the fire control blanket 4 is wound up, the diameter of the formed drum gradually increases. Due to the setting of the coil spring 8, when the gradually increasing drum formed by the fire control blanket 4 presses against the arc-shaped support plate 7, it will drive the arc-shaped support plate 7 to rotate. When the arc-shaped support plate 7 rotates, it drives the cylindrical barrel 6 to rotate. When the cylindrical barrel 6 rotates, it compresses the coil spring 8, so that the arc-shaped support plate 7 can always abut against the fire control blanket 4.

[0034] Among them, a groove 12 is opened at the rear end of the bottom of the box body 1. Two bases 13 are fixed in the groove 12. A roller 14 is installed at the bottom of the base 13. Two screw rods 15 are fixed on the inner wall of the top of the groove 12 and the front end of the bottom of the box body 1. A threaded barrel 16 is threadedly connected to the outside of the screw rod 15. A foot pad 17 is fixed at the bottom of the threaded barrel 16. A positioning plate 11 is fixed on one side of the box body 1. A convex block 18 is fixed on one side of the box door 2. A positioning hook 19 is slidably connected in the convex block 18. A positioning hole 20 is opened in the positioning plate 11. One end of the positioning hook 19 can be embedded into the positioning hole 20. A baffle 21 is fixed at the bottom of the positioning hook 19. A spring 22 is sleeved on the outside of the positioning hook 19. One end of the spring 22 abuts against the baffle 21, and the other end of the spring 22 abuts against the convex block 18.

[0035] When the opening of the box body 1 needs to be sealed by the box door 2, first pull the positioning hook 19 to drive the baffle 21 to move. When the baffle 21 moves, it compresses the spring 22. Then rotate the box door 2 to seal the opening of the box body 1. Next, release the positioning hook 19. At this time, under the resilience of the spring 22, the positioning hook 19 moves downward, so that one end of the positioning hook 19 is embedded into the positioning hole 20, thereby fixing the box door 2 and the box body 1, that is, the box door 2 seals the box body 1. In addition, since two rollers 14 are installed at the rear end of the bottom of the box body 1, the entire laying device can be towed by tilting the box body 1 backward. And the foot pads 17 installed at the front end of the bottom of the box body 1 and in the groove 12 make that when the box body 1 is moved to the required position and placed vertically, the foot pads 17 contact the ground, so that the box body 1 will not move when the fire control blanket 4 is pulled out to cover the fire source. It should be understood that in some embodiments, the bottom of the threaded cylinder 16 is preferably set to be rectangular; its structure can prevent multiple box bodies from being stacked close to each other, which is convenient for storage and transportation. Further, in some embodiments, four foot pads 17 are provided, and the four foot pads 17 are respectively arranged at the four corners close to the bottom of the above-mentioned threaded cylinder 16, as Figures 1 - 3 shown. It should be understood that Figure 2 FIG. is a schematic internal structure diagram of a laying device for a fire control blanket for quickly covering a new energy vehicle provided by the present invention. It schematically removes the side wall on the left side of the box body 1, so that the inside of the box body 1 can be shown, which is beneficial to explain the technical solutions of the corresponding embodiments of the present disclosure. It should be understood that in some embodiments, the side wall on the left side of the removed box body 1 is connected to the upper, lower, and rear side walls of the box body 1 by welding, or can also be connected by integral molding and other means. Its specific connection method is not within the scope of protection requested by the present disclosure, and those of ordinary skill in the art can also achieve it through various means of the prior art. It should also be understood that in the embodiments of the present disclosure, the so-called "laying device for a fire control blanket" in the laying device for a fire control blanket for quickly covering a new energy vehicle is called a "special box for a fire control blanket" by those of ordinary skill in the art in some application scenarios.

[0036] It should also be understood that as Figure 5 shown in the embodiment, a pull rope 23 is provided at one end of the fire control blanket 4 far from the rotating shaft 3, which is used to pull out and stretch the rolled-up fire control blanket 4 from the box body 1.

[0037] Further, in some alternative embodiments, blocking plates (not shown) are respectively provided at both ends of the rotating shaft 3. Although the inner wall of the box body can play a role in limiting the fire control blanket 4, adding a special blocking plate can better guide the fire control blanket 4 and prevent the fire control blanket 4 from shifting during the unfolding process, thereby affecting the quick unfolding and use of the fire control blanket 4.

[0038] The exemplary embodiments of the solution proposed by the present disclosure have been described in detail above with reference to the preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed by the present disclosure can be made, without exceeding the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
