DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-5 The present invention provides a technical solution: an amphibious buoy structure, including a buoy 1 with a hollow interior, wherein the upper surface of the buoy 1 is arc-shaped, and the middle part is higher and the two sides are lower, so that water is not easy to accumulate on the upper surface of the buoy 1 when the buoy 1 is on the water surface, thereby ensuring its buoyancy.

[0023] The buoy 1 includes a front end and a rear end, wherein the front end is installed on the lower side of the head of the seaplane, and the rear end is installed on the lower side of the middle or tail of the seaplane. The front end of the buoy 1 includes an arc portion 2 arranged in the middle of the buoy 1 and an inclined portion 3 symmetrically arranged on the two side surfaces of the arc portion 2. There is an arc-shaped transition between the arc portion 2 and the inclined portion 3 to form a sharper front end, so that the front end of the buoy 1 is subject to less resistance when it is on the water surface, making it more convenient for the seaplane to take off from the water surface.

[0024] A through slot 6 is provided on the front upper surface of the buoy 1, and two through slots 6 are symmetrically provided on the rear upper surface of the buoy 1. The through slots 6 are used to pass through the landing gear of the seaplane, wherein the through slot 6 at the front end is used to pass through the landing gear at the front of the aircraft, and the through slot 6 at the rear end is used to pass through the landing gear at the rear of the aircraft, so that the aircraft can take off and land on land through the landing gear, and can also take off and land on water through the buoy 1, which increases its scope of use. The buoy can respond quickly anytime and anywhere when needed, and is particularly suitable for emergency rescue and disaster relief of small civilian seaplanes.

[0025] Two sealing plates 7 are symmetrically hinged on the inner surface of the through groove 6, and a fixing frame 8 for limiting the sealing plate 7 is fixedly provided on the upper inner surface of the through groove 6. When the buoy 1 is on the water surface, the water on the lower side of the sealing plate 7 will press the sealing plate 7 upward, so the fixing frame 8 is provided to prevent the sealing plate 7 from rotating upward. After the landing gear passes through the through groove 6 and the sealing plate 7, the sealing plate 7 returns to its original position to close the through groove 6 and is limited by the fixing frame 8, thereby preventing water from overflowing from the through groove 6 to the top of the buoy 1 during take-off and landing on the water surface, ensuring the buoyancy of the buoy 1, thereby ensuring the stability of the seaplane taking off and landing on the water.

[0026] A semicircular hole is formed on the upper surface of the sealing plate 7. The two semicircular holes on the two sealing plates 7 together form a complete circular hole corresponding to the strut of the seaplane landing gear. After the landing gear passes through the through groove 6, the sealing plate 7 moves upward to reset and clamps the strut of the landing gear, and clamps the strut through the two semicircular holes.

[0027] The sealing plate 7 is made of a material with certain strength and elasticity, such as high-strength rubber, to ensure the quality and sealing performance. At the same time, it has a certain deformation capacity and can press the landing gear strut to further improve the sealing performance.

[0028] A preferred technical solution is that a sealing gasket 9 is fixedly provided at the semicircular hole of the sealing plate 7. The sealing gasket 9 is also in a semicircular ring shape. The sealing gasket 9 is also made of a material with certain strength and elasticity, such as high-strength rubber, etc. Its elasticity or deformation ability is greater than that of the sealing plate 7, which can increase the sealing of the landing gear strut part.

[0029] Further preferably, the cross-sectional shape of the sealing gasket 9 is an "I" shape, that is, it passes through the upper and lower sides of the semicircular hole and extends outward, which can increase the contact area with the sealing plate 7 and the contact area with the landing gear strut, thereby further increasing the sealing of this part.

[0030] According to the preferred technical solution, a mounting groove is provided on the inner surface of the fixing frame 8, and a telescopic rod 10 is hingedly arranged in the mounting groove. The telescopic rod 10 includes a fixing cylinder hingedly arranged in the mounting groove, the upper surface of the fixing cylinder is closed, and the lower surface is open. The inner surface of the fixing cylinder is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the sliding rod. The sliding rod is slidably arranged on the inner side of the fixing cylinder, and the bottom end of the sliding rod is hingedly arranged to the side surface of the sealing plate 7. When the landing gear passes through the through groove 6, the sealing plate 7 is pressed downward, and the sealing plate 7 rotates downward, thereby driving the telescopic rod 10 to extend and the spring to be stretched. After the landing gear passes through the through groove 6, the sealing plate 7 is not subject to external force, that is, it rotates upward and resets to the lower side of the fixing frame 8 under the drive of the telescopic rod 10 and the spring, thereby realizing the function of automatic reset sealing.

[0031] According to a preferred technical solution, two groups of slide grooves 12 are symmetrically provided on the inner two side surfaces of the through groove 6, and the two groups of slide grooves 12 correspond to the two sealing plates 7 respectively. A slide groove 12 is provided on both sides of each sealing plate 7, and the slide groove 12 is arc-shaped with the hinge point of the sealing plate 7 as the center. Slide blocks 11 are symmetrically provided on the two side surfaces of the sealing plate 7, and the slide blocks 11 are slidably arranged in the slide grooves 12. When the sealing plate 7 rotates downward, its slide block 11 also slides in the slide groove 12, thereby limiting the rotation of the sealing plate 7.

[0032] A preferred technical solution is that a plurality of grooves 5 penetrating the front and rear ends are evenly formed on the lower surface of the pontoon 1, which can reduce the overall weight of the pontoon 1 and the overall weight of the seaplane, thereby improving the load capacity of the seaplane; the three through grooves 6 are all connected to the grooves 5 at corresponding positions, so that the three through grooves 6 are shallow, making it easier for the landing gear to pass through and the structural design is also simpler.

[0033] According to a preferred technical solution, a plurality of hollow portions 4 are provided on the upper surface of the rear end of the buoy 1 , and the hollow portions 4 correspond to the grooves 5 one by one. The hollow portions 4 can further reduce the overall weight of the buoy 1 and the seaplane.

[0034] The two hollow portions 4 on the same straight line as the symmetrically arranged through slots 6 are shorter than the other hollow portions 4 , so as to ensure the overall strength of the buoy 1 .

[0035] According to a preferred technical solution, a T-shaped intermediate mounting frame 14 is fixedly provided in the middle of the upper surface of the pontoon 1, and two groups of L-shaped side mounting frames 13 are symmetrically provided on both sides of the upper surface of the pontoon 1. Mounting holes 15 are provided on the upper surfaces of the intermediate mounting frame 14 and the side mounting frames 13. The pontoon 1 is connected and installed to the lower part of the seaplane through the intermediate mounting frame 14 and the side mounting frame 13, which is convenient for disassembly, assembly, overhaul or replacement operations, is easy to maintain, and can improve the use flexibility of the seaplane.

[0036] An optional technical solution is that air bags 16 are installed on the inner sides of several grooves 5 that are not in a straight line with the through groove 6. When the seaplane takes off or prepares to land on the water surface, the air bags 16 are inflated to increase the buoyancy of the float; and when the seaplane takes off and lands on land or flies in the air, the air in the air bags 16 is discharged to reduce the aircraft resistance and the weight of the float.

[0037] A fixing ring 17 is arranged outside the airbag 16 . The fixing ring 17 is fixedly arranged inside the groove 5 . The airbag 16 is fixed and limited by the fixing ring 17 .

[0038] Further optionally, the airbags 16 are connected to a connecting tube 18, and the connecting tube 18 is arranged inside the buoy 1. The end of the connecting tube 18 passes through the upper surface in the middle of the buoy 1. An air pump can be installed in the middle of the upper surface of the buoy 1 to inflate or deflate the airbags 16; the connection between the connecting tube 18 and the buoy 1 is sealed to ensure the sealing and overall integrity of the interior of the buoy 1.

[0039] Furthermore, the air pump can also be arranged in the cabin of the seaplane, and a connecting flange 19 is arranged at the end of the connecting pipe 18, and is sealed and connected to the air pipe of the air pump through the connecting flange 19.
