[0022] In the scheme, after the buoy 1 is placed on the sea level, the first air bag 2 is inflated by the inflation mechanism, so that the buoy 1 can float on the sea surface, then the second air bag 401 is inflated by the inflation mechanism, so that the spherical antenna 4 can float and rise, so that the first connecting rope 301 is in a straightened state, when the spherical antenna 4 is stored, the second air bag 401 is deflated, and the first connecting rope 301 is wound on the first roller 3 by rotating the first roller 3 to realize the retraction of the spherical antenna 4, wherein the first connecting rope 301 includes a fixed rope for tensioning the spherical antenna 4, and a radio frequency feeder cable for connecting the spherical antenna 4 and the signal processing module inside the buoy 1 for signal transmission, the length of the radio frequency feeder cable is greater than the length of the fixed rope, so that the radio frequency feeder cable does not provide tensioning force, so as to improve the protection effect of the radio frequency feeder cable; during the observation on the sea, when the buoy 1 is inclined due to the action of the sea waves, the first connecting rope 301 can drive the first disc 5 to slide in the first sliding cavity 102 in the inclined direction due to the inclination of the buoy 1 and the straightened state of the first connecting rope 301, when the first disc 5 slides, the hinged rod 502 is driven to rotate, so that the corresponding sliding block 504 slides in the sliding groove 503, so as to compress or stretch the first spring 505, so as to provide the damping effect of the influence of the sea waves on the buoy; at the same time, when the spherical antenna 4 deviates due to the sea wind, the first connecting rope 301 drives the first disc 5 to slide in the first sliding cavity 102 in the inclined direction, so as to provide the damping effect of the influence of the sea wind on the buoy, thereby improving the stability of the buoy 1.

[0024] In the scheme, the counterweight 602 is connected by the second connecting rope 601, so that the counterweight 602 extends to the sea to improve the stability of the buoy 1. When the buoy 1 is tilted, the second connecting rope 601 drives the second disc 7 to slide in the second sliding cavity 105, so as to press the second spring 702 to provide damping effect. Meanwhile, in cooperation with the first connecting rope 301, the tension force for returning the buoy 1 is improved, so as to avoid the buoy 1 from falling down.

[0025] In an embodiment of the application, the buoy 1 is provided with a sealed chamber 107 which is communicated with the second cavity 104, a piston 8 is slidingly installed in the sealed chamber 107, the second roller 6 is installed in the sealed chamber 107, a piston hole 801 for the second connecting rope 601 to pass through is arranged on the piston 8, a connecting rod 9 is hinged between the piston 8 and the second disc 7, and the sliding second disc 7 can drive the piston 8 to slide axially along the sealed chamber 107 through the connecting rod 9. The buoy 1 is fixedly connected with a water injection tank 10 which is communicated with the sealed chamber 107 through an air pipe (not shown in the figure), the water injection tank 10 is provided with a water injection hole 11 and a water outlet hole 12 which are communicated with the outside of the water injection tank 10, a first one-way valve (not shown in the figure) which enables the seawater outside the water injection tank 10 to enter the water injection tank 10 in one direction is fixedly installed in the water injection hole 11, and a second one-way valve (not shown in the figure) which enables the seawater inside the water injection tank 10 to flow out of the water injection tank 10 in one direction is fixedly installed in the water outlet hole 12.

[0026] In the scheme, after the buoy 1 is placed on the sea, the water injection tank 10 will be partially submerged below the sea level under its own gravity, and the water injection hole 11 is covered. Under the action of water pressure, seawater will partially enter the water injection tank 10 until the pressure inside the water injection tank 10 balances with the external water pressure, so as to improve the overall weight of the buoy 1, thereby improving the stability of the buoy 1. When the buoy 1 is tilted to drive the second disc 7 to slide, the second disc 7 drives the piston 8 to move downward through the connecting rod 9, so as to stretch the air in the water injection tank 10 through the air pipe, break the pressure balance between the inside and outside of the water injection tank 10, and make the seawater enter the water injection tank 10 through the water injection hole 11, so as to improve the overall weight of the buoy 1 under the action of waves, thereby improving the stability of the buoy 1 under the action of waves. When the sea level is calm, the counterweight 602 will drive the second connecting rope 601 to be in a straight state, so as to drive the second disc 7 to return to the original position through the second connecting rope 601 and the second spring 702, thereby driving the piston to move upward through the connecting rod 9, and partially extruding the seawater in the water injection tank 10 to the outside of the water injection tank 10 through the water outlet hole 12 through the air pipe, so as to balance the pressure between the inside and outside of the water injection tank 10.

[0027] In one embodiment of the present application, the axis of the first disc 5 is in line with the axis of the second disc 7, the first through hole 501 is coaxial with the first disc 5, the second through hole 701 is eccentrically arranged on the second disc 7, and one end of the connecting rod 9 is hingedly connected to the center of the bottom side of the second disc 7.

[0028] In the present solution, the second through hole 701 is eccentrically arranged for avoiding the connecting rod 9, and when the buoy 1 is in the inclined state, the first connecting rope 301 and the second connecting rope 601 are arranged in a staggered manner, which is conducive to the return of the buoy 1 in the direction opposite to the inclination direction of the buoy 1.

[0029] In one embodiment of the present application, the bottom of the buoy 1 is fixedly connected with an annular block 13, the annular block 13 surrounds the water injection tank 10, and an annular gap is arranged between the inner wall of the annular block 13 and the outer wall of the water injection tank 10.

[0030] In the present solution, by arranging the annular gap, when the water injection tank 10 sinks below the sea level, the water pressure on the outer wall of the water injection tank 10 only comes from the seawater outside the annular gap, thereby reducing the external water pressure of the water injection tank 10, which is conducive to the balance of the internal and external pressures of the water injection tank 10 and avoids the difficulty of water flowing out of the water injection tank 10 due to excessive external water pressure.

[0031] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application 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 application.
