Description

Technical Field

[0001] The utility model relates to the technical field of rubber fenders, in particular to a fixing device for a rubber fender of an air-cushion ship. Background Art

[0002] An air-cushion ship, also known as a "hovercraft", is an air-cushion vehicle supported by an air cushion under the bottom of the ship. The air cushion is usually formed by continuously supplied high-pressure gas. Air-cushion ships are mainly used for navigation on water and ice, and can also land on some relatively smooth land terrains and floating docks. An air-cushion ship is a type of high-speed ship. When moving, since the hull rises above the water surface, the water resistance of the hull is reduced, so that the navigation speed is faster than that of ships with the same power; the speeds of many air-cushion ships can exceed fifty knots. Air-cushion ships can also travel at a very slow speed and hover on the water surface.

[0003] Most existing air-cushion ships are externally provided with rubber fenders to protect the hull, but the fixing methods are relatively single and the protection radius cannot be adjusted, resulting in the rubber fender being unable to protect the hull in some cases, thus presenting the problem of the practicality of the rubber fender. To solve such problems, a fixing device for a rubber fender of an air-cushion ship is proposed. Summary of the Utility Model

[0019] The present utility model will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0020] The following will further describe the embodiments of the present utility model in detail with reference to the drawings:

[0021] Referring to Figure 1 and Figure 2As shown in the figure, an air-cushion vehicle, also known as a "hovercraft", is a type of air-cushion vehicle supported by air cushions under the bottom of the ship. The air cushion is usually formed by continuously supplied high-pressure gas. Air-cushion vehicles are mainly used for water navigation and ice travel, and can also land on some relatively smooth land terrains and floating docks. An air-cushion vehicle is a type of high-speed ship. When traveling, since the hull rises above the water surface, the water resistance of the hull is reduced, so that the sailing speed is faster than that of ships with the same power; the speeds of many air-cushion vehicles can exceed 50 knots. Air-cushion vehicles can also travel at a very slow speed and hover on the water surface. Most existing air-cushion vehicles are externally provided with rubber fenders to protect the hull, but the fixing methods are relatively single and the protection radius cannot be adjusted, resulting in the rubber fenders being unable to protect the hull in some cases, thus presenting the problem of the practicality of the rubber fenders. To solve such problems, a fixing device for rubber fenders of an air-cushion vehicle is proposed, including an air-cushion hull 1. A groove 111 is formed in a concave shape on one side of the skirt 11 of the air-cushion hull 1. An adjusting member 12 is arranged in the groove 111. The adjusting member 12 includes a fender frame 121 slidably arranged horizontally along the inner wall of the groove 111. One side of the fender frame 121 extends outward to the outside of the air-cushion hull 1. A driving member 2 for driving the fender frame 121 to slide horizontally to adjust the protection radius of the fender frame 121 is arranged on the side of the fender frame 121 close to the groove 111. And a water-stop member for waterproofing the internal space of the groove 111 is arranged between the fender frame 121 and the groove 111; through the setting of the air-cushion hull 1 and the groove 111, the adjusting member 12 can be stably installed, and through the setting of the driving member 2, the fender frame 121 can slide horizontally in the groove 111, so as to achieve the purpose of self-adaptive adjustment of the protection radius of the fender frame 121, and achieve the purpose of wider application range of the entire fender. Also, through the setting of the water-stop member, the problem that water enters the groove 111 during the use of the air-cushion vehicle and causes abnormalities in the fender frame 121 can be avoided, making the entire fender fixing process relatively stable.

[0022] It should be noted that the specific structure of the above water-stop member is as follows: The water-stop member includes a water-stop sliding sleeve 14 arranged between the outer periphery of the fender frame 121 and the groove 111. The water-stop sliding sleeve 14 is fixedly arranged on the outer periphery of the fender frame 121 for separating the inner and outer parts of the groove 111; through the setting of the water-stop sliding sleeve 14, the area inside the groove 111 can be separated from the outside, so as to prevent external water flow from entering the inner groove 111, thus achieving the purpose of protecting the fender adjustment part.

[0023] Furthermore, in order to improve the use effect of the water-stop sliding sleeve 14, in this embodiment, a waterproof layer 13 for waterproofing is arranged on the outer side surface of the water-stop sliding sleeve 14; through the setting of the waterproof layer 13, the problem that the water-stop sliding sleeve 14 is damaged due to long-term contact with water flow can be avoided.

[0024] Additionally, between the inside of the fender bracket 121 and the driving member 2 is an area where the water-stop sliding sleeve 14 is sealed. That is to say, the groove 111 is inside the water-stop sliding sleeve 14 where gas exchange can be changed.

[0025] It should also be noted that the specific structure of the driving member 2 is as follows: The driving member 2 includes an air pump 21 disposed on one side of the groove 111. The output end of the air pump 21 extends toward the side close to the groove 111 and is used for supplying air to the sealed part of the groove 111. By setting the air pump 21, the air pressure inside the inner area of the groove 111 can be changed, so as to achieve the purpose of horizontally sliding and adjusting the entire fender bracket 121. However, it should be noted that the horizontal sliding process of the fender bracket 121 in the groove 111 has a certain stroke limit, that is to say, the fender bracket 121 does not slide without limit, so as to ensure that the protection process of the fender bracket 121 is more orderly.

[0026] Furthermore, during the process of the air pump 21 changing the air pressure inside the groove 111, when pressurizing, at this time the fender bracket 121 slides outward, so that the protection radius of the entire fender bracket 121 is increased. And when depressurizing, in order to ensure that the fender bracket 121 can retract orderly, in this embodiment, a return spring 15 for sliding and resetting the fender bracket 121 is further provided on the side of the fender bracket 121 close to the groove 111. By setting the return spring 15, the purpose of orderly retraction of the entire fender bracket 121 can be ensured, so as to achieve the purpose of orderly adjustment.

[0027] It is worth mentioning that, in order to ensure the effectiveness during the pressurizing and depressurizing processes, in this embodiment, a sealing gasket 16 for sealing the space inside the groove 111 is provided on the inner side of the fender bracket 121 in the water-stop sliding sleeve 14. By setting the sealing gasket 16, it can be ensured that the entire pressurizing and depressurizing area is in a relatively sealed and stable state, so that the pressure can be changed under the operation of the air pump 21.

[0028] Further, in order to ensure better protection effect of the fender bracket 121, in this embodiment, protective bumps 1211 are provided on the outer peripheral part of the fender bracket 121 to increase the protection area of the fender bracket 121, so as to improve the protection effect.

[0029] It should be noted that an elastic layer 1212 is provided in the head area of the fender bracket 121, while the inner area cannot be deformed, so as to ensure the sealing performance and water-stop performance.

[0030] It should be emphasized that the embodiments described in the present utility model are illustrative rather than restrictive. Therefore, the present utility model is not limited to the embodiments described in the specific embodiments. Any other embodiments obtained by those skilled in the art based on the technical solution of the present utility model also fall within the scope of protection of the present utility model.
