Description

Technical Field

[0001] The invention belongs to the technical field of offshore stable buoys, and in particular relates to a communication buoy steady-state control device suitable for offshore environments. Background Art

[0002] The offshore communication buoy is the core equipment supporting marine scientific exploration and military communications, and needs to achieve stable data transmission across media (air-water-shore). This type of buoy usually integrates shortwave communication, underwater acoustic communication and satellite relay technology. For example, shortwave skywave can achieve thousands of kilometers of over-the-horizon transmission, underwater acoustic communication covers several kilometers underwater, and Iridium or Beidou system guarantees real-time data return. Its application scenarios include deep-sea environmental monitoring, emergency communication and submarine covert communication. It needs to maintain working stability under high sea conditions (such as 12 meters wave height) and complex electromagnetic interference. The current technology is still a technical bottleneck in the impact resistance of the buoy body under dynamic sea conditions.

[0003] Existing buoy technology has significant defects in adaptability to sea conditions, structural stability and communication continuity: Insufficient wave resistance: Traditional buoys mostly use rigid anchors or single damping structures, which are prone to base frame breakage or capsizing in extreme waves, resulting in data collection interruption. This problem directly restricts the buoy's ability to continue operating in harsh sea conditions, and it is urgent to achieve multi-dimensional dissipation of wave energy and dynamic adjustment of the float's position through innovative mechanical structures. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a steady-state control device for a communication buoy suitable for an offshore environment, which realizes multi-dimensional dissipation of wave energy and dynamic adjustment of the floating body posture through an energy-consuming structure.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention includes a plurality of buffer structures uniformly arrayed around a buoy, wherein the buffer structure includes a rotating rod, a floating plate and a balancing seat; one end of the rotating rod is hinged around the buoy, and the other end is hinged above the middle of the floating plate, and the hinge axes at both ends of the rotating rod are parallel to each other and parallel to the sea level; the balancing seat is suspended below the floating plate, and the floating plate floats on the sea surface.

[0007] Furthermore, the balancing seat includes an internally sealed shell, a vertical rod is supported between the top and bottom sides of the shell, a counterweight block is slidably provided on the vertical rod, and buffer springs are respectively connected between the counterweight block and the top and bottom sides of the shell.

[0008] Furthermore, the floating plate is a disc-shaped structure, a long column is spherically hinged at the lower middle part of the floating plate, and the lower end of the long column is fixedly connected to the top end of the shell.

[0009] Furthermore, a top seat is extended above the middle of the floating plate, and the rotating rod is hinged to the top seat.

[0010] Furthermore, a spiral flow guide structure is provided along the long column.

[0011] The beneficial effects of the present invention are:

[0012] The present invention evenly arranges buffer structures around the buoy. When waves pass through the floating plate, the floating plate is driven to swing up and down. The floating plate suspends the balance seat to swing up and down around the peripheral points of the buoy through the rotating rod, so as to consume the energy of the wave impact force, reduce the impact of the wave impact on the buoy itself, and maintain the stability of the buoy. Since the wave energy below the sea level decays with the water depth (the wave energy is concentrated in the surface layer), the balance seat is less affected by the wave impact, and the balance seat can pull the buoy downward, so that the buoy overcomes the pulling force of the balance seat to consume energy. The energy-consuming structure of this device is almost below the sea level and will not affect the signal transmission and recognition of the buoy body; through multiple underwater energy-consuming structures, the waves around the buoy are blocked and energy is consumed, reducing the impact of the waves on the buoy; when the buoy has a tendency to swing, the floating plate and the balance seat provide stable mass inertia, and the rotating rod is used to pull or block the buoy, eliminate the swing amplitude of the buoy, and improve the stability of the buoy.

[0013] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention discloses a communication buoy steady-state control device suitable for offshore environment. Figure 1 , Figure 2 and Figure 3 , including a plurality of buffer structures A uniformly arrayed around the buoy 5. The buffer structures A can be arranged in different numbers according to the marine environment, and can be arranged in three groups or even six groups. In this example, it is set to four groups. The buffer structure A includes a rotating rod 1, a floating plate 2 and a balancing seat 3; one end of the rotating rod 1 is hinged to a position above the sea level around the buoy 5, and the other end is hinged to the upper middle part of the floating plate 2. The specific hinge method is that a top seat 21 is extended above the middle part of the floating plate 2, and the rotating rod 1 is hinged to the top seat 21. The hinge axes at both ends of the rotating rod 1 are parallel to each other and parallel to the sea level, wherein the hinge axes at both ends of the rotating rod 1 are made of titanium alloy with relatively large yield strength. The balancing seat 3 is suspended below the floating plate 2, and the floating plate 2 floats on the sea surface. When the floating plate 2 swings with the waves, the waves are blocked and energy is consumed.

[0021] In this scheme, a buffer structure A is evenly arranged around the buoy 5. When the wave passes through the floating plate 2, it drives the floating plate 2 to shake up and down. The floating plate 2 suspends the balance seat 3 and swings up and down around the peripheral points of the buoy 5 through the rotating rod 1, so as to consume the energy of the wave impact force, reduce the impact of the wave impact on the buoy 5 itself, and maintain the stability of the buoy 5. Since the wave energy below the sea level decays with the water depth (the wave energy is concentrated in the surface layer), the balance seat 3 is less impacted by the waves, and the balance seat 3 can pull the buoy 5 downward, so that the buoy 5 overcomes the pulling force of the balance seat 3 to consume energy. The energy-consuming structure of this device is almost below the sea level and will not affect the signal transmission and recognition of the buoy 5 body; through multiple underwater energy-consuming structures, the waves around the buoy 5 are blocked and energy is consumed, reducing the impact of the waves on the buoy 5; when the buoy 5 has a tendency to swing, the floating plate 2 and the balance seat 3 provide stable mass inertia, and the buoy 5 is pulled or blocked by the rotating rod 1, eliminating the swing amplitude of the buoy 5 and improving the stability of the buoy 5.

[0022] In a further solution, Figure 4 As shown, the balancing seat 3 includes an internally sealed shell 31, a vertical rod 32 is supported between the top and bottom sides of the shell 31, a counterweight block 34 is slidably provided on the vertical rod 32, and buffer springs 33 are respectively connected between the counterweight block 34 and the top and bottom sides of the shell 31.

[0023] In this solution, a counterweight 34 slides on the vertical rod 32 inside the balance seat 3, and is connected to the top and bottom of the shell 31 through a buffer spring 33. When the floating plate 2 shakes up and down with the waves, the counterweight 34 slides in the opposite direction due to inertia, and the spring 33 absorbs energy, suppressing the shaking of the floating plate 2 and improving the energy dissipation capacity of the balance seat 3.

[0024] In a further solution, Figure 3 As shown, the floating plate 2 is a disc-shaped structure, and a long column 4 is spherically hinged at the lower middle part of the floating plate 2 , and the lower end of the long column 4 is fixedly connected to the top end of the shell 31 .

[0025] In this solution, the float 2 is connected to the long column 4 through a spherical hinge, allowing the float 2 to rotate with the waves at sea level while the long column 4 will not swing significantly with the float 2. The suspension of the balance seat 3 provides a downward pulling force to the float 2, dissipating energy of the float 2 and preventing the shaking of the long column 4 from pulling the rotating rod 1 and the buoy 5.

[0026] For further solutions, refer to Figure 3 A spiral flow guiding structure is provided along the long column 4.

[0027] In this solution, by setting the long column 4 as a spiral guide structure, when the floating plate 2 swings up and down with the waves, the long column 4 moves up and down with the floating plate 2. The long column 4 and the floating plate 2 are spherical hinge structures. Under the traction of the floating plate 2 and the resistance of the water, the long column 4 can rotate axially in the water and maintain a vertical movement trend, further maintaining the vertical retention ability of the long column 4 and improving the vertical energy consumption capacity of the balance seat 3.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
