Description

Technical Field

[0001] This utility model relates to the field of helicopter landing pad flooring technology, and in particular to an aluminum alloy anti-slip plate for helicopter landing pads. Background Technology

[0002] Aluminum alloy anti-slip plates for helicopter landing pads are ground protection materials specifically designed for aircraft takeoff and landing. Made of aluminum alloy, they are lightweight, high-strength, and corrosion-resistant. Their surface is treated with special textures or perforations to provide effective drainage and anti-slip properties. Modular design allows for rapid assembly, and they can withstand the downwash from helicopter rotor blades and the impact forces of takeoff and landing.

[0003] Currently, the aluminum alloy anti-slip plates commonly used on helicopter landing pads are installed and fixed to the top of the landing pad via base brackets. Their main structure consists of raised anti-slip textures or particles pressed or welded onto the aluminum alloy plate surface to increase surface friction and drainage capacity, preventing personnel and helicopters from slipping in wet conditions. However, in cold seasons, especially during rain and snow, the surface temperature of these conventional aluminum alloy anti-slip plates is low, and snowflakes or rainwater can easily freeze quickly into ice on their surface and in the grooves of the anti-slip texture. Once ice forms, it not only significantly reduces the friction coefficient of the anti-slip plate surface, posing a safety hazard to personnel and helicopters, but the ice layer also adheres tightly to the aluminum alloy plate surface, making it difficult to remove. Frequent manual de-icing operations, such as shoveling ice or spraying de-icing agents, are required. This not only increases the workload of maintenance personnel and the operating costs of the landing pad, but also poses certain safety risks when performing de-icing operations in severe weather. Furthermore, manual de-icing may damage the aluminum alloy plate surface or anti-slip structure, affecting its service life and making it unsuitable for use.

[0004] Therefore, those skilled in the art have provided an aluminum alloy anti-slip plate for helicopter landing pads to solve the problems mentioned in the background art. Utility Model Content

[0010] By adopting the above technical solution, the support can be stably installed on the top of the helipad by setting the fixing plate and fixing holes, which facilitates the stable installation of the anti-slip plate body.

[0011] Optionally, a heat-conducting fin is fixedly connected to the top between the two sides of the inner cavity of the heating shell, and the top of the heat-conducting fin is attached to the insulation plate.

[0012] By adopting the above technical solution, the contact area between the insulation board and the anti-slip plate and the hot air can be increased by setting heat-conducting fins, thereby improving their heating effect.

[0015] Optionally, ventilation openings are provided around the support, and the top of the heating shell is fixedly connected to the anti-slip plate body by bolts.

[0016] By adopting the above technical solution, an air duct can be formed at the bottom of the support by setting an exhaust opening. The flowing air prevents overheating inside, and the bolt-installed heating shell makes it easy for staff to disassemble and maintain.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model utilizes a heating de-icing mechanism to continuously generate hot air through heating pipes. The hot air flows through the system via a circulating air duct and transfers heat to the insulation board via heat-conducting fins. The insulation board prevents cold air from entering, maintains the surface temperature of the anti-slip plate, and prevents ice formation during rain and snow. This avoids the reduction in anti-slip performance caused by icing in traditional anti-slip plates, reduces the frequency of manual de-icing operations, lowers the maintenance burden and operating costs of the helipad, and eliminates the safety risks associated with de-icing operations.

[0023] 2. This utility model utilizes the multi-layer structure of the anti-slip plate body, employing the honeycomb structure of the heat-conducting and temperature-equalizing layer to uniformly diffuse heat, eliminate surface temperature differences, and suppress local icing. Through the elastic base and microbead embedding of the ice-reducing elastic transition layer, the adhesion of ice crystals is reduced, promoting the brittle peeling of the ice layer and avoiding the problem of tightly adhered ice layers that are difficult to remove. The surface micro-textured anti-slip layer forms a multi-level protrusion array, piercing the water film to enhance friction, maintaining high anti-slip performance even under wet and slippery conditions, and reducing the risk of slippage for personnel and helicopters.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] Example 1:

[0033] Please refer to Figure 1-5 An aluminum alloy anti-slip plate for a helicopter landing pad includes a support 1. The top of the support 1 is fixedly connected to the anti-slip plate body 2. The bottom of the anti-slip plate body 2 is fixedly connected to the insulation board 3. The bottom of the insulation board 3 is fixedly connected to the heating and de-icing mechanism 4. The heating and de-icing mechanism 4 includes a heating shell 41. The top of the heating shell 41 is fixedly connected to the insulation board 3. The bottom of the heating shell 41 is connected to a circulation shell 42. The front and rear sides of the circulation shell 42 are connected to the heating shell 41 through conduits 43. A heating pipe 44 is fixedly connected between the two sides of the inner cavity of the circulation shell 42. The top of the circulation shell 42 is fixedly connected to an mounting plate 45. The bottom sides of the mounting plate 45 are connected to circulating fans 46.

[0034] In this embodiment: the support 1 provides stable support for the anti-slip plate body 2; the insulation board 3 increases the insulation effect of the anti-slip plate body 2 and prevents ice formation on its surface from affecting the anti-slip effect; the heating and de-icing mechanism 4 continuously generates heat to prevent ice formation on the top of the anti-slip plate body 2; the heating shell 41 continuously heats the anti-slip plate body 2; the circulation shell 42 reheats the hot air and delivers it to the interior of the heating shell 41, improving the heating effect and reducing heating energy consumption; the circulating fan 46 works with the mounting plate 45 to continuously circulate hot air; and the heating pipe 44 heats the air.

[0035] Example 2:

[0036] Reference Figure 1-5 The support 1 has a fixed plate 5 fixedly connected to the front and rear sides of both sides of the inner cavity. The fixed plate 5 has a fixed hole on the top. The heating shell 41 has a heat-conducting fin 6 fixedly connected to the top between the two sides of the inner cavity. The top of the heat-conducting fin 6 is attached to the insulation plate 3. The anti-slip plate body 2 has an anti-slip protrusion on the top. The mounting plate 45 has an installation opening on both sides of the top for use with the circulating fan 46. The support 1 has an exhaust opening around its perimeter. The top of the heating shell 41 is fixedly connected to the anti-slip plate body 2 by bolts. The anti-slip plate body 2 includes a base layer 201. The surface of the base layer 201 is provided with a heat-conducting and temperature-equalizing layer 202. The surface of the heat-conducting and temperature-equalizing layer 202 is provided with an ice-reducing elastic transition layer 203. The surface of the ice-reducing and elastic transition layer 203 is provided with a surface micro-textured anti-slip layer 204.

[0037] In this embodiment: the fixing plate 5 and fixing holes allow the support 1 to be stably installed on the top of the helipad, facilitating the secure installation of the anti-slip plate body 2; the heat-conducting fins 6 increase the contact area between the insulation board 3 and the anti-slip plate body 2 and the hot air, improving their heating effect; the anti-slip protrusions enhance the anti-slip effect of the anti-slip plate body 2; the installation opening facilitates the installation and fixing of the circulating fan 46; the exhaust opening creates an air duct at the bottom of the support 1, preventing overheating of the interior through airflow; the bolt-mounted heating shell 41 facilitates disassembly and maintenance by personnel; and the heat-conducting and temperature-equalizing layer 202 improves the temperature conductivity of the anti-slip plate body 2. The high thermal conductivity aluminum alloy honeycomb core structure rapidly diffuses heat along the plane through the pore walls, eliminating local cold zones and suppressing local icing caused by temperature differences in the anti-slip plate body 2. The ice-repellent elastic transition layer 203 reduces the adhesion of the ice layer. The ice-repellent elastic transition layer 203, formed by organosilicon modified polymer, forms an elastic base after curing. It contains uniformly distributed micro glass beads. The elastic deformation reduces the adhesion of ice crystals, and the micro beads form stress concentration points that promote the brittle peeling of the ice layer. The surface micro-textured anti-slip layer 204 is made of microporous anodized aluminum alloy. The surface is anodized to form a dense microporous oxide film, and then mechanically imprinted to form a multi-level pyramidal protrusion array, providing high friction and piercing the water film to reduce slippage.

[0038] The implementation principle of this utility model is as follows: In use, the support 1 is installed above the helipad through the fixing plate 5 and fixing holes. Multiple supports 1, together with the anti-slip plate body 2, are evenly laid on the surface of the helipad to provide stable support and anti-slip effect. In severe weather, when rainwater remains on the top of the anti-slip plate body 2 and freezes, the heating pipe 44 and the circulating fan 46 can be activated. The circulating fan 46 circulates the air inside the heating shell 41 and the circulating shell 42, while the heating pipe 44 heats the circulating air. The hot air is used to make the top of the anti-slip plate body 2... The ice layer melts quickly, and at the same time, the heat-conducting and temperature-equalizing layer 202 set on the surface of the anti-slip plate body 2 uses its honeycomb structure to evenly diffuse heat and eliminate cold areas. The ice-reducing elastic transition layer 203 reduces ice adhesion and promotes peeling through its elastic base embedded with micro glass beads. The surface micro-textured anti-slip layer 204 uses multi-level pyramidal protrusions to pierce the water film and enhance friction, preventing ice from forming in rainy and snowy weather. This avoids the decline in anti-slip effect of traditional anti-slip plates due to icing, reduces the frequency of manual de-icing operations by staff, reduces the maintenance burden and operating costs of the apron, and eliminates the safety risks of de-icing operations.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
