Description

Technical Field

[0001] This invention relates to the field of integrated mast technology, and more particularly to a multifunctional integrated stealth mast for marine applications. Background Technology

[0002] Integrated masts are one of the most important hardware components on a ship. A key characteristic of integrated masts is their capacity to house a large number of electronic devices. The structural layout of integrated masts presents significant challenges, including the rational arrangement of the spatial positions of these devices to prevent interference and the coordinated placement of cooling water pipes and cables. Currently, most integrated masts on ships suffer from insufficient integration, limited functionality, and a heavy structure, resulting in poor conformity with the ship's hull and low overall stealth performance.

[0003] Currently, most ship decks are equipped with numerous UHF, VHF, and HF antennas and radio frequency networks. This proliferation of antennas creates a complex electromagnetic environment and results in significant resource waste, especially since each electronic device is equipped with its own dedicated antenna, exacerbating this problem. To improve operational efficiency and the electromagnetic environment, it is necessary to effectively integrate the transmitting and receiving antennas of various systems. This involves adopting a comprehensive antenna, radio frequency, and signal processing approach, integrating multiple antennas into a single design to enable a single antenna to power multiple electronic devices operating in different or the same frequency bands. Summary of the Invention

[0004] The main objective of this invention is to provide a multi-functional integrated stealth mast for ships, which integrates multiple functions such as lighting, signaling, communication and navigation signal transmission and reception, and detection on the mast.

[0005] To achieve the above objectives, the present invention provides a multi-functional integrated stealth mast for ships, comprising a lightning rod, a mast light, an integrated antenna device, and a structural module arranged sequentially from top to bottom. The integrated antenna device integrates a satellite navigation integrated antenna, and the structural module includes an antenna array support and a cover located below the antenna array support. The cover integrates a 360° panoramic camera, a navigation radar, and a detection radar.

[0006] Preferably, the mast light is also equipped with an emergency light.

[0007] Preferably, the mast light is hollow, with an internal hollow channel for the lightning rod's guide wire, the mast light's cable, and the upper emergency light's cable to pass through.

[0008] Preferably, the integrated antenna device has a frustum structure, and the integrated antenna device integrates a V / UHF band antenna, a VHF band antenna, and an M / HF band antenna.

[0009] Preferably, an emergency light is also installed on the outer wall of the integrated antenna device.

[0010] Preferably, the antenna array support is a frustum-shaped structure, and a satellite communication phased array antenna is mounted on the side of the frustum-shaped structure.

[0011] Preferably, the cover is a frustum-shaped structure with a hollow interior, and multiple horizontal supports are installed inside the frustum-shaped structure to divide its interior into multiple areas.

[0012] Preferably, the housing is equipped with an upper cross brace and a lower cross brace. The upper cross brace is used to assist in fixing the integrated antenna device, and the lower cross brace is used to fix the navigation radar.

[0013] Preferably, the integrated antenna device is hollow inside, and the cables for the lightning rod, mast light, upper emergency light, satellite navigation integrated antenna and lower emergency light are all introduced downward into the structural module from inside the integrated antenna device, and all cables extend downward along the inner wall and cross braces of the structural module.

[0014] Preferably, the bottom of the structural module uses an outward-flaring steel flange to connect to the main hull deck.

[0015] The proposed multi-functional integrated stealth mast for ships integrates lightning rods, various signal lights, multi-band antennas, satellite communication phased array antennas, panoramic cameras for video surveillance systems, and navigation radar into a single design through rational layout and integration technology. This achieves the integration of multiple functions such as lighting, signaling, communication and navigation signal transmission and reception, and detection. Furthermore, the mast's overall design is a near-conical shape, with its tilt angle consistent with the ship's superstructure; this conformal design enhances the ship's overall stealth capabilities.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Reference Figure 1 In this preferred embodiment, a marine multi-functional integrated stealth mast includes a lightning rod 1, a mast light 2, an integrated antenna device 3, and a structural module arranged sequentially from top to bottom. The integrated antenna device 3 integrates a satellite navigation integrated antenna. The structural module includes an antenna array support 41 and a cover 42 (made of composite material) located below the antenna array support 41. The cover 42 integrates a 360° panoramic camera, a navigation radar, and a detection radar.

[0022] The mast is designed as a conical shape, and this conformal design improves the ship's overall stealth capabilities. The mast's angle of inclination is consistent with that of the ship's superstructure.

[0023] Furthermore, an upper emergency light is also installed on the masthead 2. In this embodiment, the masthead 2 is hollow, with an internal hollow channel for the guide wire of the lightning rod 1, the cables of the masthead 2 and the upper emergency light to pass through. The horizontal projection dimension of the multi-functional integrated stealth mast used on this ship is Ф5200, and the vertical height is approximately 10m.

[0024] The lightning rod 1, mast light 2 and emergency light are designed as a single unit and are mounted on the top of the integrated antenna device 3 with screws.

[0025] Specifically, the integrated antenna device 3 has a frustum structure, and integrates a V / UHF band antenna, a VHF band antenna, and an M / HF band antenna inside the integrated antenna device 3. The V / UHF band antenna, VHF band antenna, and M / HF band antenna are arranged sequentially from top to bottom in the internal height direction of the integrated antenna device 3.

[0026] In this embodiment, the integrated antenna device 3 is a frustum with an upper diameter of 250mm and a lower diameter of 500mm. The integrated antenna device 3 can be used by multiple devices operating at V / UHF and VHF frequencies, such as VHF radios and AIS systems. Specifically, the M / HF band in the integrated antenna device 3 enables multiple electronic devices, such as M / HF radios, navigation warning receivers, and ship weather fax machines, to receive signals. The internal cable of the integrated antenna device 3 extends downwards from the bottom side opening.

[0027] Furthermore, a lower emergency light 31 is also installed on the outer wall of the integrated antenna device 3. Three sets of lower emergency lights 31 are arranged horizontally around the bottom of the integrated antenna device 3. The working cable of the lower emergency light 31 enters the mast from the cable connector on the back through the mounting hole on the integrated antenna device 3. The lower emergency lights 31 are mounted via a mounting bracket, on which fasteners are threaded.

[0028] Specifically, in this embodiment, the antenna array support 41 is a frustum-shaped structure, and a satellite communication phased array antenna is mounted on the side of the frustum-shaped structure. The satellite communication phased array antenna is installed in the antenna array support 41 of the structural module to meet the operational requirements of the satellite communication equipment. The liquid cooling pipes and cables of the antenna array extend downward from the back of the antenna and are connected to relevant equipment inside the cabin through the interior of the structural module.

[0029] In this embodiment, the cover 42 is a frustum-shaped structure with a hollow interior. Multiple horizontal supports are installed inside the frustum-shaped structure to divide its interior into several regions. The cover 42 has an upper horizontal support and a lower horizontal support. The upper horizontal support is used to assist in fixing the integrated antenna device 3, and the lower horizontal support is used to fix the navigation radar.

[0030] The enclosure 42 is divided into three functional areas by cross braces. The top area houses a 360° panoramic camera, the middle area contains a navigation radar, and the bottom area can accommodate other detection radars or a compartment for power supply units, distribution boxes, control modules, and other equipment. All cross braces are connected to the inner wall of the cylinder. The upper cross brace secures the satellite navigation integrated antenna with screws and also helps to fix the horizontal cable section, while the lower cross brace is used to fix the navigation radar. The bottom area of ​​the enclosure 42 can accommodate other detection radars or a compartment for power supply units, distribution boxes, control modules, and other equipment.

[0031] In this embodiment, the integrated antenna device 3 is hollow inside. The cables for the lightning rod 1, mast light 2, upper emergency light, satellite navigation integrated antenna, and lower emergency light 31 are all introduced downwards from inside the integrated antenna device 3 into the structural module. All cables extend downwards along the inner wall and cross braces of the structural module. The bottom of the structural module uses an outward-flaring steel flange for connection to the main hull deck.

[0032] The proposed multi-functional integrated stealth mast for ships integrates a lightning rod, various signal lights, multi-band antennas, satellite communication phased array antennas, panoramic cameras for video surveillance systems, and navigation radar into a single design through rational layout and integration technology. This achieves the integration of multiple functions such as lighting, signaling, communication and navigation signal transmission and reception, and detection. Furthermore, the mast's overall design is a near-conical shape, with its tilt angle consistent with the ship's superstructure; this conformal design enhances the ship's overall stealth capabilities.
