Description

Technical Field

[0001] This utility model relates to the field of emergency broadcast alarm technology, specifically a digital communication shipboard emergency broadcast alarm device. Background Technology

[0002] Digital communication ships refer to vessels equipped with a Digital Select Calling (DSC) system. This system transmits predefined digital information via intermediate frequency (MF), high frequency (HF), and very high frequency (VHF) maritime radio systems. It is a core component of the Global Maritime Distress and Safety System (GMDSS) and safeguards the lives of the ship and its crew. Digital communication ships are typically equipped with emergency broadcast alarm devices to broadcast emergency alarms to surrounding crew members in the event of an emergency. Currently, emergency broadcast alarm devices on digital communication ships usually use loudspeakers to play the alarm information. Since some loudspeakers are often installed on the outside of the cabin and lack effective protective structures when not in use, they are susceptible to damage from external moisture, which in turn adversely affects the use by personnel.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, this utility model provides a digital communication marine emergency broadcast alarm device, including a protective shell 1 and a speaker 2. The right end of the top of the inner cavity of the protective shell 1 is movably connected to a rotating shaft 14 via a bearing. A second synchronous pulley 13 is fixedly installed at the middle end of the rotating shaft 14. A protective cover 4 is fixedly connected to the bottom of the rotating shaft 14. The outer surface of the protective cover 4 is movably connected to the right end of the inner cavity of the protective shell 1. A fixed frame 8 is fixedly connected to the upper end of the left side of the inner cavity of the protective shell 1. A drive motor 15 is fixedly installed at the right end of the bottom of the outer surface of the fixed frame 8. A rotating rod 21 is fixedly installed at the output end of the drive motor 15. The upper end of the rotating rod 21 is movably connected to the right end of the top of the fixed frame 8 via a bearing. A first synchronous pulley 11 is fixedly installed at the top of the rotating rod 21. A synchronous belt 12 is connected between the middle end of the first synchronous pulley 11 and the middle end of the second synchronous pulley 13.

[0025] In this technical solution, the speaker 2 is designed to allow crew members to play emergency alarm information when encountering emergencies on the digital communication ship, so that surrounding crew members can promptly detect the situation and take appropriate safety measures. The drive motor 15, rotating rod 21, first synchronous pulley 11, fixed frame 8, synchronous belt 12, second synchronous pulley 13, rotating shaft 14, protective cover 4, and protective shell 1 are designed to effectively store and protect the speaker 2 when not in use, effectively reducing the probability of damage to the speaker 2 caused by the external environment and ensuring that personnel can use it normally in the future.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 2 and Figure 4 As shown, a fixed plate 23 is fixedly connected to the middle end of the rotating rod 21. Limiting grooves 22 are provided on both sides of the fixed plate 23. A guide groove 17 is provided on the left side of the inner cavity of the fixed frame 8. Moving plates 18 are movably connected to both ends of the guide groove 17. A support spring 19 is fixedly connected between the middle ends of the two moving plates 18 that are close to each other. A limiting protrusion 20 is fixedly connected to the right end of the two moving plates 18 that are close to each other. The surface of the limiting protrusion 20 is movably connected to the surface of the limiting groove 22. A guide rod 16 is fixedly connected to the left end of the inner cavity of the fixed frame 8. The left end of the moving plate 18 is movably connected to the surface of the guide rod 16.

[0028] In this technical solution, by setting up the fixed plate 23, the limiting groove 22, the moving plate 18, the support spring 19, and the limiting protrusion 20, the fixed plate 23 and the limiting groove 22 can be driven to rotate when the drive motor 15 drives the rotating rod 21 to rotate. Under the action of the tension of the support spring 19, the limiting protrusion 20 at the right end of the moving plate 18 can be inserted into the limiting groove 22 at different positions. This can apply a certain resistance during the rotation of the fixed plate 23 and the rotating rod 21, effectively avoiding the probability of the rotating rod 21, the first synchronous pulley 11, the synchronous belt 12, the second synchronous pulley 13, the rotating shaft 14, and the protective cover 4 rotating due to the bumps during the digital communication boat's operation when the drive motor 15 stops working. By setting up the guide groove 17 and the guide vertical rod 16, the purpose of guiding the moving plate 18 is achieved, preventing the moving plate 18 from rotating or tilting during use.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a threaded sleeve 9 is fixedly connected to the left end of the bottom of the protective shell 1. A threaded seat 25 is threadedly connected to the inner cavity of the threaded sleeve 9. A container 26 is threadedly connected to the top of the threaded seat 25. A through hole 27 is opened on the surface of the container 26. A drying rod 28 is placed between the inner cavity of the container 26 and the inner cavity of the threaded seat 25. A knob 24 is fixedly connected to the bottom of the outer surface of the threaded seat 25. An anti-slip protrusion is fixedly connected to the surface of the knob 24. A receiving shell 5 is fixedly connected to the upper right end of the protective shell 1. Mounting brackets 7 are fixedly connected to both ends of the left side of the outer surface of the protective shell 1. Mounting holes 6 are opened at both ends of the mounting brackets 7. A support shaft 10 is fixedly connected to the right end of the bottom of the inner cavity of the protective shell 1.

[0032] The working principle of this utility model is as follows: By setting up the speaker 2, it is convenient for the crew to play the emergency broadcast alarm information when encountering an emergency on the digital communication ship, so that the crew around can discover it in time and take corresponding safety measures. When the digital communication ship is docked for a long time or during maintenance, and when the speaker 2 is not in use, the drive motor 15 is started to drive the rotating rod 21 and the first synchronous wheel 11 to rotate along the bearing on the fixed frame 8. The rotation of the first synchronous wheel 11 drives the second synchronous wheel 13 and the rotating shaft 14 to rotate through the synchronous belt 12. The rotation of the rotating shaft 14 drives the protective cover 4 to rotate along the inner cavity of the protective shell 1 until the protective cover 4 is positioned to the right of the speaker 2 under the action of rotation. This allows the protective cover 4 and the protective shell 1 to effectively store and protect the speaker 2, effectively reducing the probability of the speaker 2 being damaged by the external environment and ensuring that it can be used normally by personnel in the future.
