Description

Technical Field

[0001] The utility model relates to the technical field of marine electronic equipment, in particular to a fast-deployable AIS buoy. Background Art

[0002] The AIS buoy (Automatic Identification System Buoy) is a maritime navigation aid that incorporates Automatic Identification System (AIS) technology. Its main function is to provide automatic identification and positioning services for ships by sending and receiving AIS signals, thereby improving the safety and efficiency of maritime navigation. The AIS buoy has a built-in AIS module that can send and receive AIS signals. These signals contain important data such as the ship's identification information, position, speed, and heading. AIS buoys are set up at key locations such as waterways and port entrances to provide navigation assistance and safety warnings, helping maritime traffic management departments monitor ship dynamics, optimize traffic flow, and improve navigation efficiency. They serve as important navigation and positioning tools in maritime search and rescue operations.

[0003] Existing AIS buoys typically integrate multiple functions, resulting in a complex overall structure and increased size. To ensure the buoy's stable floating in various sea conditions, a large floating surface area is required, which makes the buoy occupy a large space and inconvenient to transport. Secondly, AIS buoys contain a large number of sensor transmitters and are easily impacted during transportation, affecting the stability of electronic components. Therefore, we propose a rapid deployment AIS buoy to address this problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A rapid deployment AIS buoy includes a floating body 1. Transverse grooves 2 are provided on the front, back, left, and right sides of the floating body 1. The top and bottom of the transverse grooves 2 are open. An expansion plate 3 is rotatably installed in the transverse groove 2. The sides of multiple expansion plates 3 close to each other are fixedly connected to steel wire ropes 4. One end of the multiple steel wire ropes 4 is fixedly connected to the same ring body 5. The ring body 5 is fixedly connected by two half rings through a spring pin. The steel wire ropes 4 on two adjacent expansion plates 3 are connected to the same half ring. A four-sided cone 6 is fixedly installed on the top of the floating body 1. A hollow rod 7 is fixedly installed on the top of the four-sided cone 6. The ring body 5 is slidably sleeved on the outside of the hollow rod 7.

[0023] like Figure 2 and Figure 4 As shown, a same fixed shaft 8 is fixedly installed between the inner walls on both sides of the transverse groove 2 , and the expansion plate 3 is rotatably sleeved on the outer side of the corresponding fixed shaft 8 .

[0024] Two torque springs 9 are fixedly installed on both sides of the expansion plate 3. One end of the torque spring 9 is fixedly connected to the inner wall of one side of the corresponding transverse groove 2. The torque spring 9 is wound around the outer side of the corresponding fixed shaft 8. The two torque springs 9 limit the expansion plate 3 so that it can remain in the same plane with the float 1. After the two ring bodies 5 are separated into two half rings, the two adjacent expansion plates 3 are connected by the wire rope 4, the half ring and the wire rope 4, which improves the stability of the two expansion plates 3.

[0025] like Figure 3 As shown, an inflation box 10 is fixedly installed at the bottom of the floating body 1, and several inflation mechanisms are arranged in the inflation box 10. The inflation mechanism includes a quick inflation valve and a high-pressure gas cylinder. An annular airbag 11 is fixedly sleeved on the outside of the inflation box 10, and the inflation mechanism is connected to the annular airbag 11.

[0026] like Figure 1 and Figure 5As shown, a limiting plate 12 is fixedly installed on one side of the expansion plate 3. Multiple limiting plates 12 are used to limit the annular airbag 11 after the expansion plate 3 is laid flat. After the four expansion plates 3 are spread out on a plane, the four limiting plates 12 constitute the four sides of the rectangular frame. The outer side of the annular airbag 11 is pressed on multiple limiting plates 12 to improve the overall stability.

[0027] In this embodiment, the four-sided cone 6 is hollow and a signal transmitting device is provided inside the four-sided cone 6. The signal transmitting device has a built-in AIS transmitter and antenna. The antenna extends from the top of the hollow rod 7 and is used to send and receive AIS signals to realize automatic identification and positioning of ships; the positioning system and energy system, including a GPS module and an inertial navigation system, ensure the precise positioning of the buoy at sea, and solar panels are fixedly installed on the four inclined surfaces of the four-sided cone 6. The solar panels convert solar energy into electrical energy for the energy system, providing a continuous energy supply for the buoy and ensuring the long-term stable operation of the AIS signal transmitting device; the four-sided cone 6 serves as the shell of the above-mentioned various electronic components and also has a certain buoyancy to prevent the buoy from sinking into the water.

[0028] The working principle of the present utility model is as follows: move the ring body 5 upward to separate it from the hollow rod 7, and then press the spring pin to separate the ring body 5 into two half rings. The expansion plate 3 swings downward under the action of gravity and torque spring 9 until its top is in the same plane as the top of the float 1, thereby realizing the function of expanding the surface area of ​​the float 1. Increasing the surface area of ​​the float 1 can significantly improve its buoyancy, and a larger surface area can make the center of gravity of the float 1 lower, thereby improving its stability in the water. After that, the inflation mechanism is started, and the quick inflation valve opens the high-pressure gas cylinder to allow high-pressure gas to enter the annular airbag 11. The annular airbag 11 expands outward until it is tightly abutted against multiple limit plates 12, further improving the buoyancy of the float 1.

The preferred embodiments do not describe all details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the contents of this specification.
