Description

Technical Field

[0001] The invention relates to the technical field of hovercraft, and in particular to an amphibious outdoor hovercraft. Background Art

[0002] A hovercraft is a high-speed vessel that uses the principle of surface effect to form an air cushion between the hull and a supporting surface (water surface or ground) by relying on air at a pressure higher than atmospheric pressure, allowing the hull to sail completely or partially away from the supporting surface. Existing hovercrafts rely on fans to generate thrust to move, but when moving on land, the bottom air cushion is in direct contact with the land. However, due to the large number of obstacles and gravel on land, the gravel may cut the air cushion, and directly installing wheels on the bottom of the ship will increase resistance and buoyancy in the water. Summary of the invention

[0003] In view of the above problems existing in the prior art, an amphibious outdoor hovercraft is now provided.

[0004] The specific technical solutions are as follows:

[0005] An amphibious outdoor hovercraft is designed, comprising a hull, a driving wheel, an airbag and an air filling pipe, wherein the bottom of the hull is fixedly connected to the side of the ship, a cavity is provided inside the side of the ship, the driving wheel is located below the side of the ship, an airbag is embedded outside the side of the ship, a rotating shaft is provided outside the driving wheel, the rotating shaft is fixedly connected to a supporting rod, the supporting rod passes through the side of the ship and is connected to the hull, an inner liner is provided inside the driving wheel, the inner liner is connected to a three-way pipe through the air filling pipe, and the top of the three-way pipe is connected to the airbag through a pipeline.

[0006] Preferably, an air pump is provided inside the ship's side, and the air pump is connected to the three-way pipe via threads.

[0007] Preferably, the driving wheels are made of rubber material and are symmetrically distributed.

[0008] Preferably, the airbags are distributed outside the ship's side at equal intervals.

[0009] Preferably, a fan is provided on the top of the hull.

[0010] Preferably, the driving wheel is connected to the rotating shaft by embedding, and the rotating shaft is made of stainless steel.

[0011] The above technical scheme has the following advantages or beneficial effects: an air bag is embedded on the outside of the ship's side, a rotating shaft is provided on the outside of the driving wheel, the rotating shaft is fixedly connected to the support rod, the support rod passes through the ship's side and is connected to the hull, an inner liner is provided inside the driving wheel, the inner liner is connected to the three-way pipe through an air filling pipe, and the top of the three-way pipe is connected to the air bag through a pipeline; when the device is located on land, the gas in the air bag is extracted by an air pump and the inner liner is inflated through the air filling pipe, and after the inner liner is inflated, it expands and pushes out the contracted driving wheel, and the driving wheel contacts the land to increase the height of the hull, which can protect the air bag outside the ship's side; when the device is located in the water, the gas in the inner liner can be extracted by an air pump to shrink the driving wheel, thereby reducing the contact area between the driving wheel and the water surface and reducing the resistance, which reflects the practicality and versatility of the device.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0022] Reference Figure 1-5 A kind of amphibious outdoor air cushion craft includes a hull 1, a driving wheel 4, an air bag 6 and an air filling pipe 9. The bottom of the hull 1 is fixedly connected to the ship side 2, a cavity is opened inside the ship side 2, the driving wheel 4 is located below the ship side 2, the air bag 6 is embedded outside the ship side 2, a rotating shaft 11 is arranged outside the driving wheel 4, the rotating shaft 11 is fixedly connected to the support rod, the support rod passes through the ship side 2 and connects to the hull 1, an inner liner 10 is arranged inside the driving wheel 4, the inner liner 10 is connected to the three-way pipe 8 through the air filling pipe 9, and the top of the three-way pipe 8 is connected to the air bag 6 through a pipeline When the device is located on land, the gas in the airbag 6 is extracted through the air pump 7 and the inner liner 10 is inflated through the air filling pipe 9. After the inner liner 10 is inflated, it expands and pushes out the contracted driving wheel 4. The driving wheel 4 contacts the land to increase the height of the hull 1, which can protect the airbag 6 outside the ship's side 2. When the device is located in water, the gas in the inner liner 10 can be extracted through the air pump 7, so that the driving wheel 4 contracts, the contact area between the driving wheel 4 and the water surface is reduced, and the resistance is reduced, which reflects the practicality and versatility of the device.

[0023] Furthermore, an air pump 7 is provided inside the ship's side 2, and the air pump 7 is connected to a three-way pipe 8 through a thread. The three-way pipe 8 is used to connect the airbag 6 and the inner liner 10, so that the inner liner 10 can be inflated during the process of exhausting the airbag 6.

[0024] Furthermore, the driving wheels 4 are made of rubber material and are symmetrically distributed. The driving wheels 4 can increase the height between the hull 1 and the land and protect the side of the ship 2 and the airbag 6.

[0025] Furthermore, the airbags 6 are distributed on the outside of the ship's side 2 at equal intervals. After restarting, the airbags 6 expand to expand their own area and provide buoyancy for the hull 1.

[0026] Furthermore, a fan 3 is provided on the top of the hull 1, and the fan 3 is used to generate airflow through the high-speed rotation of the internal fan, and the thrust generated by the airflow provides power for the hull 1.

[0027] Furthermore, the driving wheel 4 is connected to the rotating shaft 11 by embedding. The rotating shaft 11 is made of stainless steel. The rotating shaft 11 and the support rod are fixed under the side of the ship 2 to provide a retracted storage position and a support point for the driving wheel 4.

[0028] Working principle: When using this device, when the hull 1 is on land, the gas in the airbag 6 is extracted through the air pump 7 and the inner liner 10 is inflated through the air filling pipe 9. After the inner liner 10 is inflated, it expands and pushes out the contracted driving wheel 4. The driving wheel 4 contacts the land to increase the height of the hull 1, which can protect the airbag 6 outside the side of the ship 2. When this device is located in the water, the gas in the inner liner 10 can be extracted through the air pump 7, so that the driving wheel 4 shrinks, reducing the contact area between the driving wheel 4 and the water surface, and reducing resistance.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
