Technical Field
[0001] This utility model relates to the field of fire extinguishing technology, and in particular to a fire blanket cart. Background Technology
[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source. New energy vehicles on the market can be roughly divided into two types: pure electric and hybrid. However, both types of new energy vehicles use batteries as their power source for operation.
[0003] However, electric vehicles have been plagued by spontaneous combustion issues since their launch. When an electric vehicle's battery catches fire, traditional fire extinguishing methods are insufficient to extinguish the flames due to its sealed structure. Therefore, fire extinguishing methods that isolate the air are more efficient and can effectively prevent reignition. However, existing fire blankets are relatively large and difficult to lay on vehicles due to factors such as vehicle height and temperature. Utility Model Content
[0004] To address the problem that existing fire blankets are too large and difficult to lay on vehicles due to factors such as vehicle height and temperature during on-site operations, this application provides a fire blanket trolley, the specific solution of which is as follows.
[0005] A fire blanket trolley includes a bracket and a winding rod. The bracket is disposed on both sides of the winding rod, and the upper end of the bracket is detachably connected to the winding rod. The length of the winding rod is longer than that of the vehicle, and the height of the bracket is greater than that of the vehicle. A caster wheel is provided at the lower end of the bracket. A fire blanket is wound on the winding rod and can be detached from the winding rod. A retainer is also provided on the caster wheel to fix the direction of the caster wheel.
[0006] By adopting the above technical solution and setting up a pushable bracket, the fire blanket is wound onto the winding rod during use. One end of the fire blanket is pulled out and aligned with the burning vehicle. As the bracket is pushed toward the burning vehicle, the fire blanket is fixed by stepping on it or other means. The winding rod moves from above the vehicle, while the bracket passes by the side of the vehicle. At this time, because one end of the fire blanket is fixed, the fire blanket can gradually fall off the winding rod and cover the burning vehicle along the direction of the bracket's movement, thereby isolating and extinguishing the fire.
[0007] Optionally, the bracket includes two support rods, and the two ends of the winding rod are fitted with joints. A connecting cylinder is provided on the joint corresponding to the two support rods. The support rods are detachably connected to the connecting cylinders, and the two support rods are set at an acute angle.
[0008] By adopting the above technical solution, the bracket is equipped with two support rods arranged at an acute angle, and the support rods are detachably connected by a joint. The two support rods can form a triangular bracket, which has strong stability and strength, reducing the possibility of the support rods being damaged when the fire blanket moves, and further improving the stability of the trolley during use.
[0009] Optionally, the connecting cylinder is slidably connected to the joint, and the connecting cylinder slides along the circumference of the joint. A connecting rod is also provided between the support rods. The connecting rod includes two rod bodies that are hinged to each other and to the corresponding support rod.
[0010] By adopting the above technical solution, the connecting cylinder and the joint are slidably connected, and the support rod can adjust the height of the winding rod according to the actual situation. After adjustment, the connecting rod that fixes the position of the rod can be installed between the two rods, so that the bracket can be kept fixed, which can improve the versatility. Furthermore, the connecting rod can further improve the stability of the triangle formed by the bracket, thereby improving the stability of the bracket and the stability of the trolley during use.
[0011] Optionally, a connecting seat is fixedly provided on the support rod, and a push rod is rotatably connected to the connecting seat.
[0012] By adopting the above technical solution, a connecting seat and a push rod are set up. The push rod can be flipped out when needed and folded back when not in use, reducing the space occupied during storage and improving the convenience of storage. After being flipped out, it can push the bracket toward the burning vehicle from a greater distance, so that firefighters can keep a certain distance from the burning vehicle, thereby improving the safety of firefighting.
[0013] Optionally, the connecting seat is also provided with a positioning plate, which is used to limit the rotation range of the push rod toward the side away from the winding rod.
[0014] By adopting the above technical solutions, a positioning plate is set to limit the rotation range of the push rod, reducing the swaying of the push rod when pushing the support, and further improving the stability when pushing the support.
[0015] Optionally, the push rod is further provided with an extension rod, which is hinged to the end of the push rod away from the connecting seat, and the push rod can limit the rotation range of the extension rod.
[0016] By adopting the above technical solution, setting up an extension rod and hinged it to the connecting seat, while limiting the rotation range of the extension rod by the push rod, and reducing the swinging of the extension rod when pushed, the distance between firefighters and the burning vehicle can be further increased, thereby further improving the safety effect.
[0017] Optionally, a handle is provided on a section of the extension rod away from the hinge point, and the handle is fixedly connected to the extension rod and used for gripping.
[0018] By adopting the above technical solution, a handle is installed on the extension rod, which can be held to push the rod, thereby improving the stability and convenience of pushing the support and thus improving the efficiency of fire extinguishing.
[0019] Optionally, one end of the fire blanket is provided with a fixing blanket, which is arranged in a strip shape and parallel to the length direction of the fire blanket.
[0020] By adopting the above technical solution, a strip-shaped fixing blanket is set on the fire blanket. When fixing the fire blanket, it can be fixed by stepping on the fire blanket, so that the fire blanket can fall down and cover the burning vehicle.
[0021] In summary, this application has at least the following beneficial effects:
[0022] 1. This application solves the problem that fire blankets are large in size and difficult to lay on vehicles due to vehicle height and temperature during on-site operations. This application solves the problem by setting up a pushable bracket. When laying the fire blanket, it is necessary to first roll it up or roughly roll it up on the rolling rod on-site. After rolling, the bottom of the fire blanket only needs to be fixed by stepping on it or other means, and then it can be pushed directly to make the fire blanket fall off the rolling rod and cover the burning vehicle to complete the isolation and fire extinguishing.
[0023] 2. This application also improves safety and reduces safety hazards during firefighting by setting up foldable push rods and extension rods to increase the distance between firefighters and the burning vehicle. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0032] A type of fire blanket cart, such as Figure 1 and Figure 2 As shown, the device includes a bracket 1 and a winding rod 2. The bracket 1 is located on both sides of the winding rod 2. The length of the winding rod 2 is longer than that of the vehicle, and the height of the bracket 1 is higher than that of the vehicle. The upper end of the bracket 1 is detachably connected to the winding rod 2. The lower end of the bracket 1 is provided with a caster wheel 11. A fire blanket 3 is wound on the winding rod 2 and can be detached from the winding rod 2. A retainer 111 is also provided on the caster wheel 11 to fix the direction of the caster wheel 11. In practice, the winding rod 2 passes over the vehicle, while the bracket 1 passes over both sides of the vehicle. The fire blanket 3 can completely wrap and isolate the burning vehicle. The fire blanket 3 includes pure cotton fire blanket 3, asbestos fire blanket 3, fiberglass fire blanket 3, high silica fire blanket 3, etc. The fire blanket 3 can be pre-wound onto the winding rod 2 or roughly wound on site. As long as one end of the fire blanket 3 is fixed when pushing, the other end of the fire blanket 3 can be detached from the winding rod 2 during the pushing of the bracket 1 to complete the fire extinguishing.
[0033] like Figure 1 and Figure 2 As shown, the bracket 1 includes two support rods 12. Connectors 21 are fitted at both ends of the winding rod 2. Connecting cylinders 211 are provided on the connectors 21 corresponding to the two support rods 12. The support rods 12 are detachably connected to the connecting cylinders 211, and the two support rods 12 are set at an acute angle. The connecting cylinders 211 are slidably connected to the connectors 21, and the connecting cylinders 211 slide along the circumference of the connectors 21. A connecting rod 13 is also provided between the support rods 12. The connecting rod 13 includes two rod bodies 131, which are hinged to each other and to their corresponding support rods 12. In practice, the connecting cylinders 211 can be slidably adjusted, and the angle of the support rods 12 can be adjusted, thereby adjusting the height of the winding rod 2, allowing the winding rod 2 to pass over vehicles of different heights.
[0034] like Figure 1 and Figure 2As shown, a connecting seat 14 is fixedly mounted on the support rod 12, and a push rod 15 is rotatably connected to the connecting seat 14. A positioning plate 141 is also provided on the connecting seat 14, which limits the rotation range of the push rod 15 towards the side away from the winding rod 2. In specific implementation, the positioning plate 141 is set perpendicular to the winding rod 2, and the push rod 15, after being folded, can also be set perpendicular to the winding rod 2. Pushing the push rod 15 at this time can move the bracket 1, ensuring a certain distance between firefighters and the burning vehicle, reducing the safety hazards caused by excessive close proximity.
[0035] like Figure 1 and Figure 2 As shown, the push rod 15 is also equipped with an extension rod 16, which is hinged to the end of the push rod 15 away from the connecting seat 14. A handle 161 is provided on the section of the extension rod 16 away from the hinge point, and the handle 161 is fixedly connected to the extension rod 16 and used for gripping. In practical implementation, when not in use, both the extension rod 16 and the push rod 15 can be folded back, reducing space occupied and further improving storage convenience. Simultaneously, the extension rod 16 can further increase the distance between firefighters and the burning vehicle.
[0036] like Figure 3 As shown, one end of the fire blanket 3 is provided with a fixing blanket 31, which is strip-shaped and parallel to the length of the fire blanket 3. In practice, the fixing blanket 31 can be fixed to the ground by stepping on it. At this time, pushing the bracket 1 will gradually drop the other end of the fire blanket 3 off the burning vehicle, thereby achieving fire isolation and extinguishing. When pushing, simply moving along the fixing blanket 31 will fix one end of the fire blanket 3 and push the bracket 1.
[0037] Working principle: The fire blanket 3 is wound onto the winding rod 2, the push rod 15 and extension rod 16 are turned out, and the bracket 1 is pushed towards the burning vehicle after holding the handle 161. At the same time, the fixed blanket 31 is fixed to the ground by stepping on it. As the bracket 1 moves, the fixed blanket 31 at the other end will fall off the winding rod 2, thus covering the burning vehicle.
[0038] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
