Description

Technical Field

[0001] The invention belongs to the technical field of signal buoys, and in particular relates to a signal buoy for a submersible. Background Art

[0002] As an important underwater communication and monitoring equipment, signal buoy plays an important role in marine scientific research, underwater detection, fishery operations, etc. However, there are a series of technical difficulties in the design and application of existing signal buoys, which limits their wide application in underwater diving and deep-water operations.

[0003] First, existing signal buoys cannot meet the communication needs of underwater diving. The signal of traditional mobile wireless communication methods weakens very quickly in underwater environments, and it is almost impossible to achieve effective communication. Therefore, the signal buoy must float to the surface or close to the surface during the diving process to communicate with the shore or other equipment. This not only increases the complexity and time cost of the operation, but also has a serious impact on the continuity and safety of the operation.

[0004] Secondly, the signal buoy is not waterproof enough and cannot work stably in deep water environments. Deep water environments place extremely high demands on the sealing and pressure resistance of equipment. Once waterproof measures are not in place, seawater seeping into the buoy will cause serious consequences such as circuit short circuits and component damage.

[0005] In addition, underwater heat dissipation is also a major challenge for signal buoys. Due to the limited internal space of the buoy and the restrictions of waterproof sealing, the heat dissipation effect is often not as good as in the air. If the heat generated by heating components such as motors cannot be dissipated in time, the temperature will rise too quickly, burning the motor or damaging other components.

[0006] Finally, the smoothness of the retractable line system is crucial to the normal use of the signal buoy. If there is resistance or jamming during the retractable line, it will not only affect the operating efficiency, but may also lead to serious consequences such as cable breakage.

[0007] In summary, existing signal buoys have many technical problems in terms of communication methods, waterproof performance, heat dissipation effect, and retractable wire system. To solve these problems, we propose a signal buoy for submersibles to improve the stability and reliability of signal buoys in underwater navigation and deep-water operations.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 6 The present invention provides a signal buoy for a submersible, comprising:

[0038] The power mechanism comprises a housing and a driving motor 1 arranged inside the housing, wherein the output shaft of the driving motor 1 is connected to a rotating shaft 2;

[0039] The heat dissipation component includes an air storage bag 3 filled with heat-conducting oil, the air storage bag 3 is connected to one end of the shell, an air bag protection shell 4 is sleeved on the outer side of the air storage bag 3, the air bag protection shell 4 is detachably connected to one end of the shell, and a sealing ring is provided between the air bag protection shell 4 and the shell;

[0040] The retractable wire assembly includes a wire drum 5 and a guide ring 6. The wire drum 5 is sleeved and mounted on the rotating shaft 2. The guide ring 6 is located above the wire drum 5 and connected to the body of the submersible. A cable 7 is wound around the wire drum 5. The upper end of the cable 7 passes through the guide ring 6 and is connected to the float assembly.

[0041] The float assembly includes a shell and a communication assembly arranged in the shell. The communication assembly is a sonar or an underwater acoustic modem. A stuffing box 8 is provided below the shell. The upper end of the cable 7 passes through the stuffing box 8 and is electrically connected to the communication assembly.

[0042] As an integrated underwater communication tool, the signal buoy is designed to provide stable and reliable signal transmission solutions in the fields of deep-sea exploration and underwater operations. The core structure of the signal buoy is developed around its efficient heat transfer and communication functions to ensure excellent performance in various extreme underwater environments. First, the airbag 3 is installed on the outer shell, and the airbag protective shell 4 is set on the outside for protection. This design can not only effectively resist the impact and corrosion of the complex underwater environment, but also ensure the sealing of the internal structure to prevent seawater from infiltrating and damaging the internal components. The user can inject heat transfer oil into the shell through the airbag 3. The heat transfer oil, as a medium for heat transfer, can absorb and disperse the heat generated during the operation of the drive motor 1 inside the shell, and then conduct it to the external environment through the shell, thereby achieving efficient cooling of the drive motor 1, ensuring its stable operation in extreme environments, and extending its service life. In terms of power transmission, the output shaft of the drive motor 1 drives the shaft 2 to rotate, and the rotation of the shaft 2 further drives the reel 5 to start rotating, thereby releasing or recovering the cable 7 wound on the reel 5. The upper end of the cable 7 passes through the guide ring 6, which guides the path of the cable 7 to prevent the cable 7 from being entangled or knotted during the release or recovery process, ensuring the smooth operation of the cable 7. As the cable 7 is released, the float assembly gradually rises under the action of buoyancy until it reaches the required operating height. At this time, the communication component begins to play a key role. By adopting sonar or hydroacoustic modem technology, the signal buoy can use the good propagation characteristics of sound waves in water to achieve stable and efficient communication and data transmission with shore or other underwater equipment even in deeper waters. This communication method not only has the advantages of strong anti-interference ability and long transmission distance, but also ensures clear communication quality in complex and changeable underwater environments, providing strong technical support for deep-sea exploration and underwater operations. Through the signal buoy designed above, the heat dissipation performance, waterproof sealing, signal transmission stability and smooth use have shown good performance, which not only meets the high requirements of deep-sea exploration and underwater operations for communication tools, but also provides users with a more secure and convenient use experience.

[0043] In a specific embodiment, see Figure 2 and Figure 4The housing includes a front housing 9, a flange 10 and a rear housing 11. Sealing rings are provided between the front housing 9 and the flange 10 and between the flange 10 and the rear housing 11. The front housing 9 and the rear housing 11 are flange-connected through the flange 10. The drive motor 1 is installed inside the rear housing 11 through a motor support plate 12. The rotating shaft 2 passes through the flange 10 and the front housing 9, and is rotatably connected to the flange 10 and the front housing 9. A mechanical seal 13 is provided at the rotating position of the rotating shaft 2 and the front housing 9.

[0044] The front shell 9 and the rear shell 11 are flange-connected through a flange 10. This connection method is not only stable and reliable, but also can effectively disperse the various external forces on the shell underwater, thereby improving the overall impact resistance. At the same time, the flange connection also facilitates the disassembly and maintenance of the shell, reducing the maintenance cost. In addition, in order to further enhance the waterproof performance of the shell, sealing rings are provided between the front shell 9 and the flange 10, and between the flange 10 and the rear shell 11. These sealing rings can fit tightly and effectively prevent moisture from penetrating into the shell from the connection gap. At the same time, a mechanical seal 13 is also designed at the rotation connection position between the shaft 2 and the front shell 9, which not only ensures the flexible rotation of the shaft 2, but also effectively prevents water from penetrating from the contact surface between the shaft 2 and the shell, thereby further consolidating the waterproof barrier of the shell and ensuring the long-term stable operation of the signal buoy in the underwater environment.

[0045] In a specific embodiment, see Figure 4 A skeleton oil seal 14 is provided at the rotation position of the rotating shaft 2 and the flange 10 .

[0046] By rotatably setting the rotating shaft 2 on the flange 10 and using the skeleton oil seal 14 at the rotation position of the rotating shaft 2 and the flange 10, the space between the front shell 9 and the rear shell 11 is effectively isolated and sealed. This design prevents the heat transfer oil in the rear shell 11 from penetrating into the front shell 9, ensures the smooth circulation of the heat transfer oil in the rear shell 11, increases the contact heat exchange with the drive motor 1, thereby achieving efficient cooling of the drive motor 1, improving the heat dissipation efficiency of the drive motor 1, and ensuring its stable performance and service life under high load operation.

[0047] In a specific embodiment, see Figure 4 The output shaft of the drive motor 1 and the rotating shaft 2 are connected by a coupling 15. The coupling 15 is located inside the rear housing 11. The output shaft of the drive motor 1 and the rotating shaft 2 are both provided with a flat key 16 that matches the mounting groove of the coupling 15.

[0048] The coupling 15 serves as a connecting bridge between the output shaft of the drive motor 1 and the rotating shaft 2, and ensures the coaxiality and rotation stability between the two through the close fit of the flat key 16. This design can effectively transmit the torque of the drive motor 1, reduce energy loss during the transmission process, and improve the overall transmission efficiency.

[0049] In a specific embodiment, see Figure 5 The flange 10 is connected to a shaft seat 17 on one side of the front shell 9. Angular contact bearings 18 are provided at both ends of the shaft seat 17. A slip ring 19 is provided inside the shaft seat 17. The rotating shaft 2 passes through the angular contact bearing 18 and the slip ring 19 in sequence and is rotatably connected to the angular contact bearing 18 and the slip ring 19.

[0050] The arrangement of the shaft seat 17, the angular contact bearing 18 and the slip ring 19 ensures the stability of the rotating shaft 2 during rotation, and can effectively disperse the radial and axial loads on the rotating shaft 2, reduce wear and vibration, and enable the rotating shaft 2 to maintain good rotation performance after long-term operation, which not only extends the service life of the rotating shaft 2, but also greatly improves the operating efficiency and reliability of the overall equipment, bringing many conveniences and advantages to users.

[0051] In a specific embodiment, see Figure 6 The communication component includes an antenna mounting plate 20, a signal device 21 and multiple transceiver antennas 22. The antenna mounting plate 20 is installed in the shell. The signal device 21 and the transceiver antenna 22 are arranged above the antenna mounting plate 20. The cable 7 passes through the stuffing box 8 at the bottom of the shell into the lower shell 24 and is electrically connected to the signal device 21.

[0052] The antenna mounting plate 20 is firmly mounted in the housing, providing a solid support platform for the signal transmitter 21 and the transceiver antenna 22, so that the communication component can maintain excellent operating stability and reduce signal interruption or distortion caused by vibration or impact. In addition, the stuffing box 8 provides an additional protective layer for the cable 7, effectively preventing the intrusion of moisture and impurities, thereby ensuring the long-term stable operation of the communication component in the underwater environment.

[0053] In a specific embodiment, see Figure 6 The shell includes an upper shell 23 and a lower shell 24 , a sealing ring is provided between the upper shell 23 and the lower shell 24 , and the upper shell 23 and the lower shell 24 are flange-connected together, the stuffing box 8 is arranged at the bottom of the lower shell 24 , and the antenna mounting plate 20 is installed in the lower shell 24 .

[0054] The combination of the sealing ring and the flange connection between the upper shell 23 and the lower shell 24 ensures the sealing of the shell, effectively blocks the intrusion of moisture and impurities, and provides a strong guarantee for the stable operation of the internal communication components. At the same time, it also makes the communication components easier to install and maintain, providing strong support for the communication function of the signal buoy.

[0055] In a specific embodiment, see Figure 6 , and also includes a warning light 25. The top of the upper shell 23 is provided with an opening, and the outer side of the opening is provided with a sealing ring and a gasket, and the warning light 25 is threadedly connected to the opening.

[0056] The addition of the warning light 25 enables the signal buoy to send out an obvious visual signal when necessary to alert people around, thereby improving overall safety. The design of the sealing ring and gasket ensures the sealing of the installation of the warning light 25, prevents the intrusion of moisture and impurities, and effectively ensures the stable operation of the float assembly.

[0057] In a specific embodiment, see Figure 1 and Figure 2 The outer side of the shell is provided with a fixing bracket 26 for connecting with the submersible.

[0058] A stable and reliable connection is achieved with the submersible through the fixed bracket 26. As a connecting bridge, the fixed bracket 26 not only ensures the close connection between the signal buoy and the submersible, but also provides the necessary support and stability. At the same time, the fixed bracket 26 improves the convenience of installation and disassembly, and the signal buoy can be quickly and easily assembled or separated from the submersible, which not only reduces the difficulty and time cost of operation, but also improves the operation efficiency, so that the submersible can deploy and recover the signal buoy more flexibly and quickly when performing tasks.

[0059] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
