[0002] During firefighting operations, the rapid deployment and convenient transportation of firefighting equipment directly affect the efficiency and effectiveness of firefighting and rescue. Fire scenes require a wide variety of equipment, including fire extinguishers, hoses, fire axes, and first-aid kits, some of which are quite heavy. Therefore, specialized storage devices are needed to centrally organize and transport these items to prevent them from being scattered, lost, or damaged, while also reducing the workload of firefighters. Traditional storage devices lack mobility. Most storage devices use fixed-direction rollers, which can only move in a straight line. In scenarios such as narrow fire lanes and complex fire scenes, it is difficult to quickly adjust the direction, which affects the efficiency of transportation. Summary of the Invention
[0003] This invention provides a portable storage device for fire-fighting equipment, which aims to solve the problem of insufficient mobility of existing storage devices. Most storage devices use fixed-direction rollers, which can only achieve linear movement. In scenarios such as narrow fire lanes and complex fire scenes, it is difficult to quickly adjust the direction, which affects the transfer efficiency. To achieve the above objectives, the technical solution adopted by the present invention is as follows: a portable storage device for fire-fighting equipment is provided, including a storage box, a support member connected to the bottom of the storage box, and a wheel member connected to the bottom of the storage box and located on one side of the support member. The support member is used to support the storage box when it needs to be fixed; the wheel member is used to facilitate the movement of the storage box on the ground when it needs to be moved; and a handrail is connected to the storage box. Furthermore, the wheel assembly includes a wheel frame connected to the bottom of the storage box and a trident rotating frame rotatably connected to the wheel frame, with movable wheels rotatably connected to the trident rotating frame. Furthermore, there are two wheel frames, which are symmetrically arranged and connected by a rotating shaft. Furthermore, a motor is connected to the storage box, and the motor drive end is connected to the rotating shaft. Furthermore, a differential is connected between the motor and the rotating shaft. Furthermore, a battery is connected to the bottom of the storage box, and the battery is connected to the motor. Furthermore, a controller is connected to the handrail, and the controller is electrically connected to the motor. Furthermore, the support includes a support frame connected to the storage box and a support pad connected to the support frame. Furthermore, the support pad is made of rubber. The advantages of this invention compared to the prior art are: The wheel assembly employs a combination of a trident-shaped rotating frame and movable wheels. The trident-shaped rotating frame allows for free turning, while the wear-resistant rubber movable wheels with anti-slip textures enable flexible adaptation to various harsh road conditions, such as narrow fire lanes and complex fire scenes. This solves the problem of existing devices being limited to linear movement and inconvenient turning, significantly improving the efficiency and convenience of equipment transportation. It also addresses the issue of insufficient mobility in existing storage devices. Most storage devices use fixed-direction rollers, allowing only linear movement, which makes it difficult to quickly adjust direction in narrow fire lanes and complex fire scenes, thus affecting transportation efficiency.

Detailed Implementation To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. See Figures 1 to 6 As shown, this invention discloses a portable storage device for fire-fighting equipment, including a storage box 100, a support member 200 connected to the bottom of the storage box 100, and a wheel member 300 connected to the bottom of the storage box 100 and located on one side of the support member 200. The support member 200 is used to support the storage box 100 when it needs to be fixed; the wheel member 300 is used to facilitate the movement of the storage box 100 on the ground when it needs to be moved; and a handrail 400 is connected to the storage box 100. In this embodiment, the storage box 100 is integrally molded from high-strength aluminum alloy. Its interior is divided into multiple storage compartments by removable partitions, each suitable for different types of fire-fighting equipment such as fire extinguishers, hoses, fire axes, and first-aid kits. EVA cushioning pads are affixed to the inner walls of the storage compartments to prevent damage from collisions during transport. The top of the storage box 100 features a flip-top door, which is hinged to the box. Sealing strips are installed along the edges of the door, providing some waterproof and dustproof performance. A snap-lock mechanism is also provided on the outside of the door to ensure that the equipment will not fall off during transport. In this embodiment, two sets of support members 200 are symmetrically assembled at the four corners of the bottom of the storage box 100. The support members 200 are fixedly connected to the bottom flange of the storage box 100 by bolts, and specifically consist of a support frame 210 and a support pad 220. The support frame 210 is made of stainless steel square tube welded together, which has sufficient load-bearing strength to support the total weight of the storage box 100 and the internal fire-fighting equipment. The support pad 220 is made of high-elasticity rubber and is fixedly connected to the bottom of the support frame 210 through a vulcanization process. The rubber support pad 220 not only increases the friction with the ground to prevent slippage when the device is fixed, but also plays a role in buffering and shock absorption, reducing the impact of uneven ground on the equipment inside the storage box 100. In this embodiment, a wheel assembly 300 is installed at the center of the bottom of the storage box 100, between two sets of support members 200. The wheel assembly 300 serves as the moving mechanism of the device and is fixedly connected to the storage box 100 via a mounting base welded to the bottom of the storage box 100. Specifically, the wheel assembly 300 includes a wheel frame 310, a trident rotating frame 320, and moving wheels 330. Two wheel frames 310 are provided, symmetrically distributed on both sides of the central axis at the bottom of the storage box 100. The wheel frames 310 are made of cast steel, have high structural strength, and can adapt to complex road conditions in firefighting operations. The two wheel frames 310 are connected by a rotating shaft 340, which is machined from 45# steel. Both ends of the rotating shaft 340 are rotatably engaged with the wheel frames 310 via bearings to ensure smooth rotation. In this embodiment, a trident-shaped rotating frame 320 is rotatably connected to the bottom of each wheel frame 310 via a pivot. The trident-shaped rotating frame 320 is triangular in shape, and each of its three ends is rotatably connected to a movable wheel 330 via bearings. The movable wheel 330 is made of wear-resistant rubber with anti-slip treads on its surface, which enhances grip on complex surfaces such as mud and gravel. The design of the trident-shaped rotating frame 320 allows the movable wheel 330 to turn 360 degrees, improving the mobility of the device and facilitating flexible direction adjustment in narrow fire lanes or fire scenes. In this embodiment, to improve the mobility of the device and reduce the labor intensity of firefighters, the device is also equipped with an electric drive system, specifically including a motor 500, a differential 600, a battery 700, and a controller 800. The motor 500 is bolted to a motor mounting base at the bottom of the storage box 100. The motor 500 is a DC geared motor, characterized by high torque and stable speed. Its drive end is connected to the input end of the differential 600 via a coupling, and the output end of the differential 600 is fixedly connected to the rotating shaft 340. The differential 600 allows the two wheel frames 310 to rotate at different speeds during steering, preventing sliding friction between the moving wheels 330 and the ground, reducing tire wear, and improving steering stability. In this embodiment, the battery 700 is installed in the battery compartment at the bottom of the storage box 100. The battery compartment is fixedly connected to the storage box 100 by bolts. The battery 700 is a lithium battery, which has a large capacity and long endurance, and can meet the power requirements of long-term firefighting operations. The battery 700 is connected to the motor 500 through wires to provide power to the motor 500. At the top of one side of the storage box 100, a handrail 400 is fixedly welded. The handrail 400 is made of stainless steel round tube bent into shape, conforming to ergonomic design, and is easy for firefighters to hold. At the grip position of the handrail 400, a controller 800 is installed. The controller 800 is fixedly connected to the handrail 400 by screws. Its surface is provided with control buttons for forward, backward, turn, and stop. The controller 800 is electrically connected to the motor 500 and the battery 700 through wires, which can realize the start, stop, speed, and direction control of the motor 500. The advantages of this invention compared to the prior art are: The wheel assembly employs a combination of a trident-shaped rotating frame and movable wheels. The trident-shaped rotating frame allows for free turning, while the wear-resistant rubber movable wheels with anti-slip textures enable flexible adaptation to various harsh road conditions, such as narrow fire lanes and complex fire scenes. This solves the problem of existing devices being limited to linear movement and inconvenient turning, significantly improving the efficiency and convenience of equipment transportation. It also addresses the issue of insufficient mobility in existing storage devices. Most storage devices use fixed-direction rollers, allowing only linear movement, which makes it difficult to quickly adjust direction in narrow fire lanes and complex fire scenes, thus affecting transportation efficiency. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
