Description

Technical Field

[0001] The present invention belongs to the technical field of remote transmission of deep - sea observation information, and particularly relates to an antenna deployment and holding device suitable for information transmission of sea - level observation buoys. Background Art

[0002] With the continuous in - depth development of marine scientific research, real - time data monitoring and information transmission in deep - sea areas have become a key area in the international competition of marine exploration technologies. In the deep - sea and far - sea scenarios, traditional observation means, such as submarine optical cables and research vessels, have exposed many limitations. The laying and maintenance costs of submarine optical cables are extremely high, and their coverage is very limited, making it difficult to meet the wide - ranging needs of deep - sea exploration; research vessels are restricted by sailing time and sea areas and cannot achieve long - term and continuous monitoring of deep - sea areas. Existing technologies have proposed to solve the problem of large - capacity information transmission across deep - sea and far - sea areas by setting up floating air balloons with spherical antennas on their surfaces. It uses a self - releasing large - aperture satellite communication antenna and a high - speed forwarding channel of high - throughput satellites such as Zhongxing series to achieve real - time back - transmission of deep - sea scientific exploration information globally. This innovative design breaks through the geographical space limitations of traditional observation platforms and lays a solid technical foundation for building a global ocean observation network. However, automatically releasing floating air balloons at sea will cause changes in the gravity of the overall float, affect the water - surface gravity balance, and even lead to the problem of float capsizing, affecting the retention and long - term operation of the floating air balloons. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an antenna deployment and holding device suitable for information transmission of sea - level observation buoys, which can adaptively adjust the float carrying the floating air balloon and improve the stability of the float under harsh sea conditions.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The present invention includes a floating air balloon. The floating air balloon includes a ring frame for supporting outside the floating air balloon, and further includes a spherical antenna provided on the surface of the floating air balloon. The ring frame is horizontally arranged. It also includes a high-pressure inflator for inflating the floating air balloon. A floating ring is provided around the high-pressure inflator. A number of balance water injection parts are evenly arranged around the floating ring. The balance water injection part includes a vertical through pipe. A number of water tanks are evenly arranged around the through pipe. The top of the water tank is open, and the bottom of the water tank is communicated with the through pipe. The communication parts of the number of water tanks and the through pipe are arranged in sequence from bottom to top. A piston head is hermetically slidably arranged in the through pipe. The piston head is located at the bottom end of the through pipe. A pull rope extends upward from the piston head. The upper ends of the number of pull ropes are evenly connected to the ring frame. When the floating air balloon is not inflated, it is placed above the floating ring. The high-pressure inflator is communicated with the floating air balloon, and the inside of the water tank is not filled with water.

[0006] Further, at least two guide rods are vertically arranged in the middle of the through pipe. The piston head is slidably arranged on the guide rods. A top block is further provided at the top end of the piston head. A number of inner grooves are provided around the top block. A rack is provided on one side of the inner groove. A plug is thread-sealed at the communication part of the water tank and the through pipe. A part of the plug leaks out from the inner side of the through pipe and is provided with a gear. As the piston head moves upward, the rack meshes with the gear and screws out the plug.

[0007] Further, a sinking groove is provided at the top of the top block. A plug pin is slidably arranged on the side of the sinking groove. A spring is supported between the plug pin and the inside of the piston head. The spring supports the plug pin so that the plug pin abuts against the side of one of the guide rods. The guide rod abuts against the plug pin to make the plug pin extend into the sinking groove. The lower end of the pull rope is sleeved on the plug pin.

[0008] Further, a one-way air valve is provided at the open top of the water tank.

[0009] Further, a protective outer ring is provided on each balance water injection part. The protective outer ring surrounds the outside of the number of water tanks.

[0010] The beneficial effects of the present invention are as follows:

[0011] The present invention realizes the system stability control through a dynamic buoyancy compensation mechanism. When the high-pressure gas cylinder injects gas into the floating air balloon, the volume of the floating air balloon expands and generates an upward buoyancy force, driving the entire device to gradually leave the water surface. At this time, the floating ring has a shallower draft due to the reduced buoyancy force. To prevent the device from capsizing due to sudden changes in buoyancy, the system automatically adjusts through the following steps. When the ring frame of the floating air balloon rises, the piston head in the through pipe is synchronously pulled upward by the pulling rope. During the upward movement of the piston head along the through pipe, the communication ports between the water tank and the through pipe are sequentially opened, and seawater is injected into the water tank layer by layer from the bottom of the through pipe. As the water volume in the water tank increases, the total weight of the system gradually rises, the volume of the displaced seawater expands, and the buoyancy force and gravity are rebalanced, keeping the device in a stable floating posture. This process ensures that the center of gravity of the device is always in a balanced state during the ascent of the floating air balloon through the dynamic matching of buoyancy and gravity, avoiding capsizing or attitude instability caused by sudden changes in buoyancy. This device requires no external energy or manual intervention, automatically realizes buoyancy compensation through mechanical linkage, adapts to the deep-sea unattended scenario, and the layered water injection into the water tank forms continuous buoyancy adjustment, which can buffer the impact of wind and waves on the device and improve the stability under harsh sea conditions.

Detailed implementation mode

[0022] The present invention discloses an antenna deployment and holding device suitable for information transmission of sea-level observation buoys. Referring to Figure 1 and Figure 2 , it includes a floating balloon 1. The floating balloon 1 includes a ring frame 11 for supporting on the outside of the floating balloon 1. The inside of the floating balloon 1 is also supported by arranging a carbon fiber skeleton. It also includes a spherical antenna 12 arranged on the surface of the floating balloon 1. After the floating balloon 1 floats in the air, this component is mainly used for cross-domain large-capacity information transmission in scenarios far from land such as the deep sea area. Based on the large-aperture satellite communication antenna that unfolds and ascends by self-release and relying on the high-speed satellite communication forwarding channel of high-throughput satellites such as Zhongxing series, it can realize the real-time monitoring of deep-sea scientific exploration information globally. The ring frame 11 of the floating balloon 1 is a rigid ring and is horizontally arranged in this structure. It also includes a high-pressure gas charging tank 2 for inflating the floating balloon 1. A floating ring 3 is arranged around the high-pressure gas charging tank 2. The floating ring 3 is not the main component floating on the water surface. A number of balance water injection parts 4 are evenly arranged around the floating ring 3. As shown in Figure 3 and Figure 4 , the balance water injection part 4 includes a vertically arranged through pipe 41. A number of water tanks 42 are evenly arranged around the through pipe 41. The top of the water tank 42 is open, and the bottom of the water tank 42 is communicated with the through pipe 41. The communication parts of the number of water tanks 42 and the through pipe 41 are arranged in sequence from bottom to top. A piston head 43 is hermetically slidably arranged in the through pipe 41. The piston head 43 is located at the bottom end of the through pipe 41. A pull rope 44 extends upward from the piston head 43. The upper ends of the number of pull ropes 44 are evenly connected to the ring frame 11. When the floating balloon 1 is not inflated, it is placed above the floating ring 3. The high-pressure gas charging tank 2 is communicated with the floating balloon 1. The inflation hole of the high-pressure gas charging tank 2 faces upward and is butted against the non-inflated floating balloon 1. After inflation, it is separated from the floating balloon 1. The floating balloon 1 gradually floats upward during the inflation process and finally floats in the air. In the non-inflated state, the piston head 43 blocks the through pipe 41, so that the inside of the water tank 42 is in a state of not being filled with water.

[0023] The device realizes the system stability control through a dynamic buoyancy compensation mechanism. When the high-pressure gas charging tank 2 injects gas into the floating balloon 1, the volume of the floating balloon 1 expands and generates an upward buoyancy force, driving the entire device to gradually lift off the water surface. At this time, the floating ring 3 has a shallower draft due to the reduced buoyancy. To prevent the device from capsizing due to sudden changes in buoyancy, the system automatically adjusts through the following steps. When the ring frame 11 of the floating balloon 1 rises, the piston head 43 in the through pipe 41 is synchronously pulled upward by the pull rope 44. During the upward movement of the piston head 43 along the through pipe 41, the communication ports between the water tank 42 and the through pipe 41 are sequentially opened, and seawater is injected into the water tank 42 layer by layer from the bottom of the through pipe 41 upwards. As the water volume in the water tank 42 increases, the total weight of the system gradually rises, the volume of the displaced seawater expands, and the buoyancy and gravity are rebalanced, keeping the device in a stable floating posture. This process ensures that the center of gravity of the device is always in a balanced state during the ascent of the floating balloon 1 through the dynamic matching of buoyancy and gravity, avoiding capsizing or attitude instability caused by sudden changes in buoyancy. This device, without external energy or manual intervention, automatically realizes buoyancy compensation through mechanical linkage, adapts to the deep-sea unattended scenario. The layered water injection into the water tank 42 forms continuous buoyancy adjustment, which can buffer the impact of wind and waves on the device and improve the stability under harsh sea conditions.

[0024] In a further solution, as Figure 4 shown, at least two guide rods 45 are vertically arranged in the middle of the through pipe 41, the piston head 43 is slidably arranged on the guide rods 45, and a top block 46 is further provided at the top of the piston head 43. Referring to Figure 6 and Figure 7 , a number of inner grooves 461 are formed around the top block 46, a rack 462 is provided on one side of the inner groove 461, the communication part between the water tank 42 and the through pipe 41 is thread-sealed with a plug 47, and a part of the plug 47 leaks out from the inside of the through pipe 41 and is provided with a gear 471. As the piston head 43 moves upward, the rack 462 meshes with the gear 471 and screws out the plug 47.

[0025] In this structure, the piston head 43 is guided by arranging two guide rods 45. A sealed sliding state is achieved between the piston head 43 and the guide rods 45, which can be realized by components such as O-rings. The two guide rods 45 can keep the piston head 43 from rotating in the through pipe 41 while guiding. This structure can ensure the precise meshing of the inner groove 461 of the subsequent top block 46 and the gear 471 of the plug 47. As the piston head 43 moves upward, the rack 462 meshes with the gear 471 to screw off the plug 47. After the piston head 43 moves upward beyond the connection position, the water tank 42 is connected to the seawater through the through pipe 41. By adding a threaded plug 47 to this device, the water tank 42 and the through pipe 41 are sealed and blocked to prevent seawater from flowing back into the water tank 42 from the upper end of the through pipe 41. And as the piston head 43 moves upward, the plug 47 can be removed to connect the water tank 42 and the through pipe 41 again, ensuring the subsequent water filling of the water tank 42.

[0026] In a further solution, as Figure 5 , Figure 6 shown, a sunk groove 463 is formed at the top of the top block 46. A latch 464 is slidably arranged on the side of the sunk groove 463. A spring 465 is supported between the latch 464 and the inside of the piston head 43. The spring 465 supports the latch 464 to make the latch 464 abut against the side of one of the guide rods 45. The guide rod 45 abuts against the latch 464 to make the latch 464 extend into the sunk groove 463. The lower end of the pull rope 44 is sleeved on the latch 464.

[0027] The device achieves the dynamic connection and separation of the pull rope 44 and the piston head 43 by means of a locking and releasing structure composed of a bolt 464 and a spring 465. In the initial state, the bolt 464 on the side of the sunk groove 463 at the top of the top block 46 is supported by the spring 465 and abuts against the side of the guide rod 45. Due to the blockage of the guide rod 45, part of the bolt 464 extends into the sunk groove 463, and the lower end of the pull rope 44 is sleeved on the bolt 464, thereby realizing the reliable connection between the pull rope 44 and the piston head 43. When the pull rope 44 is driven by the rising floating air balloon 1 to drive the piston head 43 to move upward, this connection can ensure the synchronous movement of components such as the piston head 43 and the top block 46. When the piston head 43 continues to move upward with the pull rope 44, the top block 46 gradually moves away from the guide rod 45. At this time, the bolt 464 loses the blockage of the guide rod 45 and retracts from the sunk groove 463 under the elastic force of the spring 465. As the bolt 464 retracts, the pull rope 44 loses its lock and disconnects from the top block 46. After that, the piston head 43, the top block 46, and the plug 47 in the top block 46 stay in the through pipe 41 due to the lack of continuous traction of the pull rope 44, while the pull rope 44 continues to float in the air with the floating air balloon 1; this structure avoids the small components such as the piston head 43, the top block 46, and the plug 47 from being completely removed from the through pipe 41 with the pull rope 44 and falling into the sea, reducing the risk of marine pollution. At the same time, it also reduces the cost of frequently replacing components due to component loss. Moreover, it also prevents these small components from falling and causing bumps to the floating device, reducing the possibility of device damage, extending the service life of the floating device, and reducing the maintenance cost; it also reduces the load-bearing weight of the floating air balloon 1, enabling the floating air balloon 1 to rise to the predetermined height more easily, improving the lifting efficiency and stability of the floating air balloon 1, reducing energy consumption, and also avoiding the traction components from causing bumps to the floating air balloon 1 in the air, reducing the risk of damage to the floating air balloon 1, ensuring the integrity and normal operation of the floating air balloon 1, and improving the stability of information transmission. This device is also beneficial to the recovery of components such as the piston head 43 and the top block 46, and these components can be reused after simple inspection and maintenance, reducing the use cost of the device and improving the utilization rate of resources.

[0028] In a further solution, as Figure 3 shown, a one-way air valve 421 is provided at the top opening of the water tank 42. The one-way air valve 421 allows the air in the water tank 42 to be quickly discharged when filling with water, avoiding the formation of air resistance and ensuring that seawater can be smoothly injected into the water tank 42. When the water tank 42 is filled with water, the one-way air valve 421 automatically closes to prevent seawater from flowing back into the through pipe 41 when the device shakes or tilts.

[0029] In a further solution, as Figure 2 shown, a protective outer ring 5 is provided on each of the balanced water injection parts 4, and the protective outer ring 5 surrounds the outside of several water tanks 42. The protective outer ring 5 can protect the water tanks 42 from being bumped against the environment such as reefs during the floating process.

[0030] 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 them. 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 to it in form and details without departing from the scope defined by the claims of the present invention.
