[0002] When various vessels pass under inland river bridges or through locks, they may encounter situations where the top of their communication antenna exceeds the lowest point of passage, requiring the antenna to be laid down for smooth passage. Since communication antennas are generally fixed with base bolts, laying the antenna down requires loosening the bolts and cable bundles, and taking protective measures, which is time-consuming and labor-intensive. It is necessary to optimize the antenna installation method to minimize the difficulties of hot work and cutting to modify the antenna after the vessel is put into service. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to solve the problem of quickly lowering the antenna and avoiding damage. The ship antenna lowering device has the advantages of convenient operation and high efficiency.

[0004] This invention provides a device for laying down an antenna that can be locked and stopped on demand, the device comprising:

[0005] Crank handle;

[0006] A transmission rod, the crank is connected to one end of the transmission rod, and a first bevel gear is provided at the other end of the transmission rod;

[0029] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0030] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0031] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0032] This invention provides a device for laying down an antenna that can be locked and laid down as needed, such as... Figures 1 to 3 As shown, the device includes:

[0033] Handle 11. Handle 11, as the manually operated input, is typically made of corrosion-resistant metal and features a good ergonomic design, facilitating rotational operation on the ship's deck. It converts human power into mechanical energy through rotational motion, serving as the power source for the entire device.

[0034] A transmission rod 12 is connected to one end of a crank handle 11, and a first bevel gear 13 is provided at the other end of the transmission rod 12. The transmission rod 12 is used to transmit the rotational torque of the crank handle 11, and is usually made of high-strength alloy steel, possessing good torsional resistance and corrosion resistance to adapt to marine environments. The first bevel gear 13 is fixed to the end of the transmission rod 12 by key connection or welding, and is used to convert the horizontal rotational force into the vertical driving force, realizing a 90-degree change in the transmission direction.

[0035] Worm gear combination, such as Figure 3As shown, the device includes a worm gear 14 and a worm 15, which can drive each other and lock in position when the transmission stops. One end of the worm 15 is connected to a second bevel gear 16, which meshes perpendicularly with a first bevel gear 13. The worm gear assembly is the core transmission and locking component of this device. After receiving the rotational force from the second bevel gear 16, the worm 15 drives the worm gear 14 to rotate. Due to the self-locking characteristic of the worm gear assembly, when the worm stops rotating, the worm gear cannot drive the worm in the opposite direction, thus achieving the function of "stop and lock simultaneously". This characteristic ensures that the antenna can stop and lock in any position during the lowering or raising process, preventing the antenna position from shifting due to ship swaying or external forces, and improving the safety and stability of the system.

[0036] A rotating guide shaft 17 is fitted with a worm gear 14. The rotating guide shaft 17, as the driven shaft of the worm gear 14, directly bears the torque transmitted by the worm gear and transmits the rotational motion to the U-shaped rotating frame 18. It is typically made of high-strength stainless steel with an anti-corrosion treatment to ensure long-term reliability in high-salt-spray marine environments.

[0037] The U-shaped rotating frame 18 is connected to both ends of the rotating guide shaft 17, and the antenna 19 is mounted on the U-shaped rotating frame 18. The U-shaped rotating frame 18 provides a mounting platform for the antenna and is used to rigidly connect the bottom of the antenna 19, enhancing structural stability. The U-shaped rotating frame 18 is rigidly connected to the rotating guide shaft 17, ensuring that the antenna 19 moves synchronously during rotation. Its material can be lightweight, high-strength aluminum alloy, balancing strength and weight control.

[0038] Turning the crank handle 11 drives the transmission rod 12. Driven by the transmission rod 12, the first bevel gear 13 drives the second bevel gear 16. The second bevel gear 16 drives the worm gear 15, which in turn drives the worm wheel 14. The worm wheel 14 drives the rotating guide shaft 17, which in turn drives the U-shaped rotating frame 18 to rotate, thereby rotating the antenna 19. This transmission path realizes a complete power transmission chain from manual operation to antenna rotation. Through multi-stage transmission and direction conversion, the operator can achieve precise angle adjustment of a heavy antenna with relatively low operating force. Furthermore, due to the self-locking characteristics of the worm gear, the antenna can be stably stopped at any angle, greatly improving operational convenience and safety.

[0039] This invention, through the combination of a hand crank and a worm gear, allows for quick adjustment of the antenna position, locking the antenna position immediately upon release, significantly reducing the labor intensity of operators and offering high safety and practicality.

[0040] In some embodiments, such as Figure 1 and Figure 2As shown, the device also includes a housing 20 with a accommodating space 21. The housing 20 serves as the outer shell of the entire device, protecting the internal transmission components from corrosion caused by the marine environment (such as seawater, salt spray, ultraviolet radiation, etc.). It is typically made of well-sealed cast aluminum or stainless steel, and the internal accommodating space 21 is used to centrally install the transmission mechanism, improving the overall structural integration and protection level.

[0041] The transmission rod 12 is equipped with a first bevel gear 13, one end of which is located within the accommodating space 21, and the other end extends out of the housing 20 and connects to the crank handle 11. This structural design ensures that the input end of the transmission rod 12 (connected to the crank handle 11) is located outside the housing for easy operation, while the output end (connected to the first bevel gear 13) is located inside the housing and is well protected to prevent transmission failure due to external impact or corrosion.

[0042] The worm gear assembly is housed within the receiving space 21. Placing the worm gear assembly inside the housing effectively prevents it from being exposed to the external environment, avoiding the entry of impurities such as sand and moisture into the meshing surfaces, which could cause wear or jamming, thus extending its service life. Simultaneously, the housing can be filled with grease to further improve transmission efficiency and durability.

[0043] The connection between the rotating guide shaft 17 and the worm gear 14 is located within the accommodating space 21, with both ends extending out of the housing 20. This design achieves "internal and external transmission" of power: the middle section of the rotating guide shaft 17 is located inside the housing and is driven by the worm gear, while both ends extend to the outside to connect to the U-shaped rotating frame 18, ensuring that the antenna can rotate outside the housing while maintaining the closedness and safety of the internal transmission system.

[0044] In some embodiments, such as Figure 1 As shown, a base 22 is provided at the bottom of the housing 20 for connecting to the deck. The base 22, as the connecting component between the housing and the ship's deck, can adopt a fastening, riveting, flange, or welding connection structure, possessing high strength and vibration resistance. Its design must consider the turbulence and impacts of the ship during navigation, ensuring the entire device remains stable and fixed in a dynamic environment, preventing loosening or displacement.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 20 has a first through hole 23, a second through hole 24, and a third through hole 25. These through holes provide necessary passageways for the transmission components, ensuring the continuity of power transmission. The positions and dimensions of the through holes are machined to correspond to the dimensions of the transmission components to ensure coaxiality with the transmission rod and rotating guide shaft, reducing uneven wear and energy loss during operation.

[0046] The first through hole 23 is used to install the transmission rod 12.

[0047] The second through hole 24 and the third through hole 25 are arranged opposite to each other and are used to set the rotary guide shaft 17.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, reinforcing structures 26 are provided at the edges of the first through hole 23, the second through hole 24, and the third through hole 25. The reinforcing structure 26 is a thickened boss or an inlaid bearing seat, used to enhance the mechanical strength of the through hole edges, prevent the hole wall from cracking or deforming due to long-term stress or vibration, and improve the overall structural reliability of the housing.

[0049] In some embodiments, a lubricating layer is provided on the surface of the reinforced structure 26. The lubricating layer may be a polytetrafluoroethylene (PTFE) coating or a solid lubricating material, used to reduce the coefficient of friction between the drive rod and the through hole, reduce wear and energy loss, and prevent jamming caused by corrosion, thereby improving smooth operation and maintenance cycle.

[0050] In some embodiments, the bottom surface of the housing 20 is provided with drainage holes to prevent water accumulation in the accommodating space 21. The drainage holes provide the housing with active drainage capability, especially in environments where water may accumulate on ship decks, effectively draining rainwater or seawater that seeps into the housing, preventing internal components from corroding and failing due to long-term immersion, and improving the environmental adaptability and reliability of the device.

[0051] This invention provides a ship equipped with a stop-and-lock antenna reclining device as described in any of the above embodiments.

[0052] This vessel integrates a stop-and-lock antenna lowering device, enabling rapid, safe, and reliable angle adjustment of the antenna system. Especially when passing under bridges, entering ports, or encountering severe weather, operators can quickly lower the antenna to avoid collisions or damage; while during normal navigation, the antenna can be quickly erected and locked to ensure uninterrupted communication. This device significantly improves the maneuverability and safety of the ship's communication system and is suitable for various types of commercial vessels, warships, and offshore operation platforms.

[0053] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
