When designing the pontoons, various critical working conditions need to be considered to ensure that the aircraft does not have an excessive roll angle, resulting in problems such as the aircraft components such as the wings and propellers hitting the water. When the pontoons are accidentally damaged in the water and the lateral stability on the water surface is reduced, in order to ensure the safety of the aircraft, it is necessary to provide the aircraft with the ability of emergency lateral stability. Summary of the Utility Model

A plurality of mounting grooves are formed on the outer surface of the pontoons. An inflatable airbag is arranged in each mounting groove. An inflation assembly and a pressure sensor are also arranged in the pontoons. The inflation assembly is communicated with the inflatable airbag. Both the inflation assembly and the pressure sensor are electrically connected to a control assembly.

[0004] In some possible embodiments, the mounting grooves are formed at positions of the pontoons close to the center of buoyancy, and the plurality of mounting grooves are distributed along the circumferential direction of the pontoons.

[0005] In some possible embodiments, the pressure sensor is arranged at the upper part of the pontoon and inside the skin.

[0006] In some possible embodiments, all the inflatable airbags are respectively communicated with the inflation assembly through air pipes, and electromagnetic valves are arranged on all the air pipes. The electromagnetic valves are connected to the control assembly.

[0007] In some possible embodiments, the inner wall of the mounting groove is hermetically bonded to the surface of the inflatable airbag. After the inflatable airbag is inflated, it protrudes from the outer surface of the pontoon.

[0008] The beneficial effect of the utility model is that: the utility model arranges a plurality of mounting grooves on the outer surface of the pontoons, and inflatable airbags are installed in the mounting grooves. A pressure sensor and an inflation assembly are also arranged in the pontoons. The pressure sensor and the inflation assembly are both connected to an external control assembly. The inflation assembly can inflate the inflatable airbags. When in use, the pressure sensor measures the pressure of the pontoons and sends the measurement information to the control assembly. The control assembly controls the inflation assembly to start and inflate the inflatable airbags. Therefore, it can provide emergency lateral stability for the aircraft when the pontoons are damaged, and ensure the safety of the aircraft when operating on the water surface.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0016] Refer to Figures 1 to 4A device for providing emergency lateral stability of a seaplane on the water surface is shown. It includes a pontoon 1 and several inflatable bags 2. A plurality of mounting grooves 3 are formed on the outer surface of the pontoon 1, and the several inflatable bags 2 are correspondingly arranged in the mounting grooves 3. A pressure sensor 5 and an inflation assembly 4 are further arranged in the pontoon 1. Both the pressure sensor 5 and the inflation assembly 4 are connected to an external control assembly, and this control assembly can adopt a conventional and mature solution in the industry, which usually includes a programmable logic controller. In this embodiment, the inflation assembly 4 can be a conventional air pump. The specific use is as follows: The pressure sensor 5 detects the pressure of the pontoon 1 and the duration of the pressure, and sends the detection signal to the control assembly. The control assembly controls the inflation assembly 4 to start according to the received signal to inflate the inflatable bags 2. After the inflatable bags 2 are opened, the drainage volume of the pontoon 1 can be increased, thereby increasing the lateral restoring moment of the seaplane and achieving the purpose of increasing the lateral stability of the seaplane on the water surface to ensure the safety of the seaplane during water operation. It should be noted that the present invention aims to protect the structural design of the device. The calculation analysis and control logic of the control assembly are not within the protection scope of the present invention, and the calculation analysis and control logic of the control assembly can both adopt conventional and mature solutions, so they will not be elaborated here.

[0017] In some possible embodiments, the mounting grooves 3 are formed at positions of the pontoon 1 close to the center of buoyancy, and the several mounting grooves 3 are distributed along the circumferential direction of the pontoon 1. The inflatable bags 2 are correspondingly installed in each of the mounting grooves 3.

[0018] In some possible embodiments, the pressure sensor 5 is arranged at the upper part of the pontoon 1 and inside the skin. When the aircraft is operating on the water surface, the pressure sensor 5 can detect the pressure of the pontoon 1 relative to the water surface and send the detection signal to the control assembly. The control assembly can judge whether the lateral stability of the aircraft on the water surface is sufficient according to the detection signal. When the lateral stability of the aircraft on the water surface is insufficient, the control assembly controls the inflation assembly 4 to start to inflate the inflatable bags 2, thereby increasing the drainage volume of the pontoon 1 and providing additional and emergency lateral stability for the aircraft on the water surface.

[0019] In some possible embodiments, all the inflatable bags 2 are respectively connected to the inflation assembly 4 through air pipes (not shown in the figure), and electromagnetic valves are arranged on all the air pipes. All the electromagnetic valves are connected to the control assembly. That is, the control assembly can not only control the opening and closing of the electromagnetic valves, but also individually control whether each inflatable bag 2 is inflated or retracted, that is, it can accurately realize the inflation or inflation amount of a certain or several inflatable bags 2.

[0020] In some possible embodiments, the groove wall of the installation groove 3 is hermetically bonded to the surface of the air-filled balloon body 2. After the air-filled balloon body 2 is inflated, it protrudes from the outer surface of the floating cylinder 1, so as to achieve the purpose of increasing the drainage volume. It should be noted that a through hole is provided at the bottom of the installation groove 3. One end of the ventilation pipe is connected to the output end of the inflation assembly 4, and the other end passes through the through hole and communicates with the air-filled balloon body 2. To ensure the sealing performance at the ventilation pipe and the through hole, a sealing ring or sealant is usually provided at this place. In the present utility model, the part of the air-filled balloon body 2 located in the installation groove 3 is hermetically connected to the groove wall and the groove bottom of the installation groove 3, thereby improving the sealing effect.

[0021] As described above, the above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
