Description

Technical Field

[0001] The present invention belongs to the technical field of the design of moored balloon systems, and particularly relates to a high-sea-capable shipborne moored balloon system. Background Art

[0002] At present, in China, maritime communication, search and rescue, and maritime monitoring all rely on shipborne or airborne communication systems and satellite-assisted communication, unmanned aerial vehicles, etc. Affected by the earth's curvature, the effective operating ranges of these communication and monitoring means are very limited. At the same time, satellites are greatly affected by factors such as climate and environment and cannot conduct real-time and continuous monitoring. Unmanned aerial vehicles have a small load capacity and a short endurance time, cannot meet the requirements of working continuously over long distances, and are also costly. The shipborne moored balloon system has a series of advantages such as a long stay time in the air, a wide detection range, a strong carrying capacity, a high low-altitude detection accuracy, and a high cost performance ratio compared with shore-based fixed communication platforms, shipborne or airborne communication detection, etc. It is an economical, efficient, convenient, and reliable communication and monitoring platform. Compared with vehicle-mounted moored balloons, the main differences of shipborne moored balloons lie in the working environment and the installation carrier. Marine environmental factors such as high radiation, high salt spray, and waves have a greater impact on shipborne equipment, especially the impact of the ship's sway on the sphere, mooring cable, and mooring platform.

The helium gas supply device can inflate the sphere. The mooring platform is connected to the stabilizing platform through a slewing bearing. The mooring platform is equipped with a cable winch device and a guiding device.

The cable winch device can take in and pay out the mooring cable to compensate for the heave displacement of the ship platform; the guiding device can guide the mooring cable.

[0007] Preferably, it further includes an attitude sensor for collecting attitude data of the ship's roll, pitch, and heave.

Specific implementation manner

[0019] The present invention is realized through the following technical solutions.

[0020] A high-sea adaptability shipborne tethered balloon system, including a ship platform 1, helium gas supply equipment 2, a mooring platform 3, a tethered balloon 4, a stabilization platform 5, a bolt 6, an attitude sensor 7, a cable winching device 8, a slewing bearing 9, a slewing drive motor 10, an on-sphere attitude sensor 11, a wind speed and direction sensor 12, a buffer 13, a course angle sensor 14, a mooring cable 15, a guiding device 16, a spring shock absorber 17, a mechanical rigging 18, as Figures 1 to 3 shown.

[0021] The ship platform 1 is the carrier of the entire system, on which the helium gas supply equipment 2, the stabilization platform 5 and the attitude sensor 7 are installed. The stabilization platform 5 is connected to the ship platform 1 through bolts 6 to ensure that the stabilization platform 5 and the ship platform 1 form an integral body, preventing the tethered balloon system from tipping over when the ship platform 1 sways under the influence of waves. The helium gas supply equipment 2 is mainly used for inflating the sphere during the initial erection of the system and for replenishing helium during daily use. The mooring platform 3 is connected to the stabilization platform 5 through a slewing bearing 9. The mooring platform 3 is the installation platform of the entire equipment, on which mainly a cable winching device 8 and a guiding device 16 are installed. The tethered balloon 4 is fixed to the mooring platform 3 through a mooring cable 15.

[0022] The stable platform 5 is mainly used to ensure that the mooring platform 3 can rotate normally when the ship platform 1 sways under the influence of waves. The attitude sensors 7 on the ship platform 1 collect the attitude data of the ship's roll, pitch, and heave. The data is calculated and controlled by the control system of the stable platform 5 to make the corresponding telescopic cylinders perform corresponding movements, so as to keep the upper platform of the stable platform 5 horizontal and ensure that the mooring platform 3 can rotate normally. When the tethered balloon 4 is in the ship mooring state, when the hull swaying effect exceeds the compensation range of the stable platform 5, the mooring platform 3 will not be able to rotate normally. The heading angle of the tethered balloon 4 and the wind direction are measured by the attitude sensor 11 on the balloon and the wind speed and direction sensor 12. At the same time, the heading angle data of the mooring platform 3 is measured by the heading angle sensor 14. When the difference between the two heading angles exceeds the set threshold, the rotary drive motor 10 installed on the mooring platform 3 will be controlled to drive the slewing bearing 9 to rotate, so that the headings of the mooring platform 3 and the tethered balloon 4 are kept consistent, realizing the active feathering of the mooring platform 3 and the tethered balloon 4 and improving the wind resistance of the system.

[0023] The cable winch and reel device 8 is a winch with an active heave compensation function. By collecting the heave motion signal of the ship platform 1 through the attitude sensor 7, the compensation amount for the corresponding cable winch and reel is calculated, and the cable winch and reel device 8 is controlled in real time to wind and unwind the cable to compensate for the heave displacement of the ship platform 1, ensuring that the tension on the mooring cable 15 is constant and preventing the tethered balloon 4 and the mooring cable 15 from being subjected to impact loads, thereby ensuring the safety of the tethered balloon 4 and the mooring cable 15.

[0024] The mooring cable 15 is mainly used for mooring the tethered balloon 4. At the same time, the control equipment on the tethered balloon 4 can be powered and communicated through the mooring cable 15. A buffer 13 is installed at the upper end of the mooring cable 15. When the hull sways and there is an impact load on the mooring cable 15, the impact on the sphere can be reduced through the buffer 13.

[0025] The guiding device 16 mainly functions to guide the mooring cable 15 and reduce the impact load. The guiding device 16 is connected to the mooring platform 3 through a slewing device and can swing left and right together under the action of the mooring cable 15 to ensure consistency with the cable direction. A shock-absorbing spring is installed on the guiding device 16, and the middle guide wheel can move up and down a short distance under load to achieve a buffering effect. Under the action of the shock-absorbing spring, the load on the mooring cable 15 is reduced, realizing the protection of the mooring cable 15.

[0026] The mechanical rigging 18 is used for mooring the tethered balloon 4 in the mooring state. A spring shock absorber 17 is installed on it, which can play a buffering role when there is relative movement or asynchrony between the mooring platform 3 and the tethered balloon 4 during startup, rotation, and braking of the mooring platform 3, reducing the impact load on the mechanical rigging 18 and the tethered balloon 4.

[0027] The protection scope of the present invention is not limited to the above embodiments. Obviously, those skilled in the art can make various changes and deformations to the present invention without departing from the scope of the present invention. If these changes and deformations fall within the scope of the claims of the present invention and their equivalent technologies, the intention of the present invention also includes these changes and deformations.
