Description

Technical Field

[0001] This invention relates to the field of emergency rescue equipment technology, specifically to a mudflat walking device for emergency rescue. Background Technology

[0002] Mudflats are tidal flats located along the coast between high and low tide levels. They are shallow beaches formed by the deposition of silt carried by rivers or ocean currents at relatively flat river mouths or near the coast. Rescue personnel often need to enter mudflat areas to conduct search and rescue operations during natural disasters (such as floods and tsunamis) or maritime accidents. However, the muddy, slippery, and poorly supported surface of mudflats, along with the potential for hidden pits or obstacles, pose significant difficulties and dangers to the rapid movement of rescue personnel.

[0003] However, it still has some drawbacks. For example, currently, when rescuers enter mudflat areas, they usually can only wear ordinary rain boots or waders, trudging through the mud with great difficulty, which easily leads to them getting stuck. This not only consumes a lot of energy and affects the speed of rescue, but also poses a safety risk of getting trapped. Although there are some equipment on the market, such as sleds and swamp skates, to increase the contact area, they are not designed for professional mudflat rescue scenarios and have obvious shortcomings: First, they are single-function, only providing buoyancy support and cannot help rescuers maintain balance or carry necessary rescue tools (such as ropes, first aid kits, probes, etc.). Rescuers still have to carry heavy equipment, further increasing the burden of movement and the risk of loss of balance; second, they lack ergonomic grip and foot pedal designs, making them difficult to control effectively in slippery environments, and easy to slip or fall; third, existing equipment is usually bulky, making it inconvenient to transport and store.

[0004] Therefore, there is an urgent need for a walking device specifically designed for tidal flat rescue environments. It can not only effectively prevent sinking, but also integrate multiple functions such as support, balance, and tool carrying, enabling rescuers to carry out rescue work safely and efficiently in such special terrains. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an emergency rescue tidal flat walking device, which aims to solve the technical problems of rescuers easily sinking, having difficulty moving, consuming a lot of physical strength, and being inconvenient to carry rescue tools when walking in tidal flat environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an emergency rescue mudflat walking device, characterized in that it comprises: a main body, the main body being a plate-like structure; a handrail, vertically fixed to one end of the upper surface of the main body; a support base, connected between the handrail and the main body, for reinforcing the handrail; side holes and hand-held holes, penetratingly formed on the main body; and a foot fixing groove, disposed in the middle of the upper surface of the main body.

[0007] Furthermore, it also includes a detachable toolbox, which can be placed on the upper surface of the main body.

[0008] Furthermore, the main body is made of a buoyancy material.

[0009] Furthermore, the contour of the foot fixing groove is adapted to the shape of the human foot, and its inner surface is provided with anti-slip texture.

[0010] Furthermore, the outer surface of the handrail is covered with an anti-slip sleeve.

[0011] Furthermore, the detachable toolbox is detachably connected to the main body via snaps or Velcro.

[0012] Beneficial effects: Compared with the prior art, the beneficial effects of the present invention are: 1. By incorporating a main body and foot-fixing grooves, the invention effectively prevents sinking and provides stable support. The main body features a large-area plate-like design, allowing rescuers to stand with both feet within the foot-fixing grooves. This distributes body weight over a larger area, significantly reducing pressure on the mudflats and fundamentally preventing excessive force at a single point from causing sinking. The foot-fixing grooves securely restrain the feet in the correct position, preventing slippage during walking or exertion, ensuring stability and safety.

[0013] 2. The inclusion of handrails and a detachable toolbox enhances balance and integrates functionality. The vertically positioned handrails provide rescuers with a reliable grip, allowing them to maintain balance and prevent falls on slippery, uneven mudflats. The detachable toolbox allows essential rescue tools to be moved with the device, freeing up rescuers' hands and integrating walking support with equipment carrying. This allows rescuers to focus more on the search and rescue operation, improving overall rescue efficiency. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Please see Figures 1 to 4This invention provides an emergency rescue mudflat walking device. The core of the device is the main body 1. The main body 1 is a plate-like structure with sufficient area. Its shape can be designed as an approximate ellipse, rectangle with rounded corners, or other streamlined shapes, aiming to reduce resistance during movement while ensuring effective support area. The dimensions of the main body 1 must fully consider ergonomics; its length should be sufficient to accommodate an adult rescuer standing with both feet in a staggered stance, and its width should provide stable lateral support. The main body 1 is preferably made of lightweight, high-strength materials, such as high-strength engineering plastics (e.g., PE, PP), composite materials, or aluminum alloy. A more preferred option is that the main body 1 uses closed-cell foam material or is filled with lightweight buoyancy material (e.g., polyurethane foam), which gives the device itself a certain degree of buoyancy. When in shallow water or in case of accidental fall into the water, the device can provide additional buoyancy support, increasing the safety of the rescuer. The bottom surface of the main body 1 can be designed with anti-slip patterns or raised ribs to increase friction with the mudflat surface and prevent backward slippage or side slippage. A handrail 2 is vertically fixed to one end of the upper surface of the main body 1. The height of the handrail 2 should be designed to be suitable for rescuers to hold when standing naturally, typically 80-110 cm. The handrail 2 itself should have sufficient strength and rigidity to withstand part of the rescuer's weight and the pulling force required to maintain balance. To ensure comfortable grip and anti-slip properties, the outer surface of the handrail 2 should ideally be covered with a soft, non-slip sleeve, which can be made of rubber, silicone, or foam. The connection between the handrail 2 and the main body 1 is crucial and requires reinforcement via the support base 3. The support base 3 is a structural component whose bottom is firmly connected to the main body 1 (e.g., by bolts or welding), and whose upper part connects to the lower section of the handrail 2. The support base 3 can be designed as a triangular plate, an arch, or a block structure with reinforcing ribs. Its function is to effectively transfer and distribute the force on the handrail 2 to the main body 1, preventing stress concentration at the connection point and ensuring the overall structural stability and reliability. Various functional holes are provided on the surface of the main body 1, mainly including side holes 4 and hand-held holes 5. Side openings 4 are located on the sides or front and rear of the main body 1 at appropriate positions. One of their main functions is to reduce the overall weight of the device, achieving lightweighting without sacrificing too much structural strength. Another important function is that ropes can pass through these side openings 4 for securing the device when multiple people are needed to work together or when towing is required by external vehicles or boats. Handhold openings 5 ​​are usually located on the main body 1 near the handrail 2, and their size is suitable for a person to reach in and grasp. These handhold openings 5 ​​provide multiple uses: firstly, when not in use, they facilitate rescuers to lift the device for short-distance movement or transport; secondly, in specific situations (such as when a low-profile crawl is required), rescuers can abandon the handrail 2 and directly operate the device through the handhold openings 5. A foot fixing groove 6 is provided in the middle of the upper surface of the main body 1. The foot fixing groove 6 is one of the key designs of this invention.The groove's contour should conform to the shape of a human foot (usually a shoe shape) and have sufficient depth to confine the forefoot or entire foot. The inner surface of the foot-fixing groove 6 should be designed with anti-slip textures or covered with anti-slip mats to increase the friction between the sole of the foot and the bottom of the groove, preventing the feet from sliding in the groove in wet conditions. When rescuers use it, they step into the foot-fixing groove 6. At this time, the weight of the human body is fully transferred to the main body 1 through both feet. Since the area of ​​the main body 1 is much larger than the contact area of ​​a single foot, according to the pressure formula P=F / S, under a constant pressure F (human weight), the significant increase in the force-bearing area S causes a sharp decrease in the pressure P on the mudflat. This is the core physical principle that enables the device to effectively prevent sinking. The presence of the foot-fixing groove 6 ensures that the foot will not slip off the device when exerting force to walk, allowing the "push-forward" action to be effectively completed. In addition, to further enhance the practicality of the device, a detachable toolbox 7 can be placed on the upper surface of the main body 1. The detachable toolbox 7 is used to store essential rescue supplies such as first-aid kits, signal lights, high-energy food, drinking water, ropes, and knives. The toolbox 7 is preferably detachable from the main body 1, secured by clips, Velcro, or elastic straps. This design allows the toolbox 7 to be removed to reduce weight when a large number of tools are not needed; it also facilitates the individual management and replenishment of the items inside. The integration of the detachable toolbox 7 combines the functions of a "walking platform" and "supply carrier," enabling rescuers to operate with minimal equipment, concentrating all essential gear in one unit, thus improving autonomy and efficiency.

[0021] Working principle: Rescuers first check that all components of the device are securely connected. They then place the necessary rescue tools into the detachable toolbox 7 and secure it to the main body 1. Next, the rescuer places both feet into the foot-fixing slots 6 on the main body 1. They then naturally grip the handrails 2. When moving, similar to using skis or water skis, one foot supports the device while the other foot is slightly lifted, propelling the entire device forward; this is done alternately. In muddy or high-resistance areas, the handrails 2 can be used for assistance. Multiple devices can be linked together via ropes through the side holes 4, or connected to a rear support point if necessary, ensuring safety. Upon reaching the rescue location, tools can be retrieved from the toolbox 7 to begin the rescue. In summary, this invention, through its large main body, dedicated foot-fixing slots, stable handrails, and integrated toolbox design, effectively solves the problems of rescuers sinking into mudflats, difficulty moving, and inconvenience when carrying heavy loads. It provides a safe, efficient, and multifunctional specialized walking equipment with significant practical value and promotional significance.
