Description

Technical Field

[0001] This utility model relates to the field of marine communication technology, and in particular to a signal transmitting device for marine communication equipment. Background Technology

[0002] Marine communication equipment signal transmitters are key components of ship communication systems. They are responsible for converting voice, data, navigation, and other information from the ship into electromagnetic wave signals and transmitting them to predetermined frequencies to achieve effective communication between ships and between ships and shore. These devices typically include transmitters, antennas, and feeders, and feature high power, long-distance transmission, and strong anti-interference capabilities. They ensure stable and reliable information transmission in the complex and ever-changing marine environment, guaranteeing safe navigation and smooth maritime operations.

[0003] Existing marine communication equipment signal transmitters generally adopt a fixed design and lack angle adjustment function, which limits the direction of signal transmission. Furthermore, they are directly fixed to the ship's plate without a stabilizing mechanism, making them prone to interference with signal transmission when the ship rolls. This affects the coverage, effect, and stability of communication, and urgently needs to be improved to adapt to the complex and ever-changing needs of maritime communication. Utility Model Content

[0004] One objective of this invention is to provide a signal transmitting device for marine communication equipment. This invention addresses the problems mentioned in the background that existing marine communication equipment signal transmitting devices generally adopt a fixed design, lack angle adjustment function, resulting in limited signal transmission direction, and are directly fixed to the ship's plate without a stabilizing mechanism, making it easy for the ship to interfere with signal transmission when it rolls, thereby affecting the coverage, effect and stability of communication.

[0005] The marine communication equipment signal transmitting device according to an embodiment of the present utility model includes:

[0006] An angle adjustment mechanism includes a protective box. Inside the protective box, a rotating cylinder is rotatably mounted via a support assembly. A rotating platform and a first gear are fixedly mounted at the upper and lower ends of the rotating cylinder, respectively. A rotating shaft is rotatably mounted inside the rotating cylinder. A first bevel gear and a second gear are fixedly mounted at the upper and lower ends of the rotating shaft, respectively. The first gear and the second gear are rotated via a drive assembly. A second bevel gear is meshed with the upper outer side of the first bevel gear. The second bevel gear is fixed to the outer side of a rotating rod. A signal generating device is connected to the outer side of the rotating rod via a fixed seat.

[0007] The stabilization mechanism includes a guide plate fixed to the bottom of the protective box and a positioning base fixed to the ship plate, wherein a balancing component for improving the stability of the signal transmitting device is installed between the guide plate and the positioning base.

[0008] Preferably, the support assembly includes legs and a bracket, with the legs fixed to both sides of the bracket.

[0009] Preferably, the drive assembly includes a first bearing housing and a motor. The two first bearing housings are rotatably equipped with helical blades. The helical blades are fixed to the output end of the motor by a coupling. The helical blade on the left is meshed with a first gear for transmission, and the helical blade on the right is meshed with a second gear for transmission.

[0010] Preferably, the first bearing housing is fixed to the inside of the support leg, and the motor is fixed inside the protective box.

[0011] Preferably, the rotating rod is rotatably disposed inside the rotating platform.

[0012] Preferably, the balancing assembly includes a damper fixed inside the positioning base and a support plate fixed inside the guide plate. A second bearing seat is fixedly provided at the output end of the damper. A roller is rotatably provided at the upper end of the second bearing seat. A positioning column is fixedly provided at the bottom of the support plate. A centering support rod is symmetrically fixedly provided at the bottom of the positioning column.

[0013] Preferably, the roller is rolled on the surface of the positioning post, and the centering support rod is located on both sides of the roller and is used to limit the movement of the roller.

[0014] The beneficial effects of this utility model are:

[0015] This invention effectively avoids the signal coverage blind spot problem caused by the inability to dynamically adjust the antenna direction in traditional fixed designs by setting an angle adjustment mechanism. When the motor starts, the output end drives the two spiral blades on both sides to rotate synchronously through the coupling. The left spiral blade drives the first gear to drive the entire rotating drum to rotate horizontally, and the right spiral blade drives the second gear to drive the rotating shaft to rotate vertically. The power is converted into the pitch motion of the rotating rod through the meshing of the first bevel gear and the second bevel gear, thereby quickly adjusting the transmission angle according to actual needs, thus optimizing the signal coverage range and enhancing the communication effect.

[0016] This invention effectively avoids the resonance offset of signal transmission equipment caused by hull rolling through a stabilizing mechanism. When the hull rolls or tilts, the positioning base is rigidly fixed to the hull plate, while the guide plate is floatingly connected to the second bearing seat through a damper. The rollers roll on the surface of the positioning column and are limited by the centering support rod. During severe rolling, the damper absorbs the impact kinetic energy through hydraulic oil throttling, and the rollers roll along the arc trajectory of the positioning column. The wedge-shaped guide surface of the centering support rod forces the support plate to automatically return to its original position, forming dynamic balance compensation and ensuring the continuity and stability of communication in complex and ever-changing maritime environments.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-4 Marine communication equipment signal transmitting device, including:

[0025] Angle adjustment mechanism 1 includes a protective housing 101. Inside the protective housing 101, a rotating cylinder 109 is rotatably mounted via a support assembly. A rotating platform 110 and a first gear 108 are fixedly mounted at the upper and lower ends of the rotating cylinder 109, respectively. A rotating shaft 112 is rotatably mounted inside the rotating cylinder 109. A first bevel gear 113 and a second gear 111 are fixedly mounted at the upper and lower ends of the rotating shaft 112, respectively. The first gear 108 and the second gear 111 rotate via a drive assembly. The drive assembly includes a first bearing housing 104 and a motor 106. Helical blades 105 are rotatably mounted inside the two first bearing housings 104. The helical blades 105 are fixed to the output end of the motor 106 via a coupling 107. The left helical blade 105 is connected to the first gear... The 108 meshing transmission configuration includes a right-side helical blade 105 meshing with a second gear 111. A second bevel gear 114 meshes with the upper outer side of the first bevel gear 113. The second bevel gear 114 is fixed to the outer side of the rotating rod 115. A signal generating device is connected to the outer side of the rotating rod 115 via a fixed base 116. When the motor starts, the output end drives the two helical blades to rotate synchronously via a coupling. The left helical blade drives the first gear to rotate the entire rotating drum horizontally, while the right helical blade drives the second gear to rotate the rotating shaft vertically. The meshing of the first and second bevel gears converts power into the pitch motion of the rotating rod, allowing for rapid adjustment of the transmission angle according to actual needs, thereby optimizing the signal coverage.

[0026] The stabilizing mechanism 2 includes a guide plate 201 fixed to the bottom of the protective box 101 and a positioning base 202 fixed to the ship plate. A balancing assembly for improving the stability of the signal transmitting device is installed between the guide plate 201 and the positioning base 202. The balancing assembly includes a damper 203 fixed inside the positioning base 202 and a support plate 208 fixed inside the guide plate 201. A second bearing seat 204 is fixedly installed at the output end of the damper 203. A roller 205 is rotatably installed at the upper end of the second bearing seat 204. A fixed base is installed at the bottom of the support plate 208. Positioning post 206 has a centering support rod 207 symmetrically fixed at its bottom. When the hull rolls or tilts, the positioning base is rigidly fixed to the hull plate, while the guide plate is floatingly connected to the second bearing seat through a damper. The roller rolls on the surface of the positioning post and is limited by the centering support rod. During violent shaking, the damper absorbs the impact kinetic energy by throttling hydraulic oil, and the roller rolls along the arc trajectory of the positioning post. The wedge-shaped guide surface of the centering support rod forces the support plate to automatically return to its original position, forming dynamic balance compensation, which ensures the continuity and stability of communication in the complex and ever-changing maritime environment.

[0027] Example 1: The support assembly includes a support leg 102 and a bracket 103. The support leg 102 is fixed to both sides of the bracket 103, and the first bearing seat 104 is fixed to the inner side of the support leg 102. The support assembly enables the signal generating device to have good stability during angle adjustment. The motor 106 is fixed inside the protective box 101, and the rotating rod 115 is rotatably disposed inside the rotating table 110.

[0028] Example 2: The roller 205 is rolled on the surface of the positioning post 206, and the centering support rod 207 is located on both sides of the roller 205 and is used to limit the roller 205. The roller rolls along the arc trajectory of the positioning post, and the wedge-shaped guide surface of the centering support rod forces the support plate to automatically return to its original position, forming dynamic balance compensation.

[0029] Working principle: In angle adjustment mechanism 1, after the motor 106 starts, it drives the spiral blades 105 on both sides to rotate synchronously through the coupling 107. The left spiral blade 105 meshes with the first gear 108, driving the rotating drum 109 to rotate horizontally as a whole; the right spiral blade 105 meshes with the second gear 111, driving the rotating shaft 112 to rotate vertically. The first bevel gear 113 on the rotating shaft 112 meshes with the second bevel gear 114 fixed to the outside of the rotating rod 115, converting the power into the pitch motion of the rotating rod, thereby quickly adjusting the angle of the signal generating device, optimizing the signal coverage range, and stabilizing the mechanism 2. The guide plate 201 passes through... The damper 203 and the second bearing seat 204 form a floating connection with the positioning base 202. When the hull rolls or tilts, the positioning base 202 is rigidly fixed to the hull plate, while the guide plate 201 floats relatively under the action of the damper 203. The roller 205 rolls on the surface of the positioning post 206 and is limited by the centering support rod 207. When there is violent shaking, the damper 203 absorbs the impact kinetic energy by throttling the hydraulic oil. The roller 205 rolls along the arc trajectory of the positioning post 206. The wedge-shaped guide surface of the centering support rod 207 forces the support plate 208 to automatically return to its original position, forming dynamic balance compensation to ensure the stability and reliability of signal transmission.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
