Description

Technical Field

[0001] This utility model relates to the field of broadcasting, and in particular to a joint emergency voice broadcasting device. Background Technology

[0002] In joint emergency response operations, voice broadcasting devices are core equipment for ensuring efficient information transmission. They are required to transmit rescue instructions, evacuation guidance plans, safety warnings, and reassurance notices to on-site rescue personnel and affected people in real time, which directly affects the efficiency of emergency response, the effectiveness of on-site order control, and the safety of people's lives and property.

[0003] Currently, most existing joint emergency voice broadcasting devices on the market adopt the traditional method of fixed installation of multiple loudspeakers or installation of a single loudspeaker with an angle adjustment mechanism. The former is not only expensive, but also involves too many devices, and the disassembly and installation of the loudspeakers is cumbersome, consuming manpower and time. The latter's adjustment mechanism can mostly only achieve single horizontal or vertical swing, unable to make multi-directional adjustments simultaneously, resulting in limited sound transmission direction and relatively unsatisfactory sound coverage. In emergency situations, personnel are often widely distributed, and a broadcasting design that cannot transmit sound in all directions and over a large area will directly lead to a significant decrease in information transmission efficiency in emergency work, and in severe cases, may even miss the best rescue opportunity, causing unnecessary casualties. To address the above problems, we propose a joint emergency voice broadcasting device to solve these issues. Utility Model Content

[0004] The purpose of this invention is to provide a joint emergency voice broadcasting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a joint emergency voice broadcasting device, comprising a support column, an adjustment mechanism, and a broadcasting module. The adjustment mechanism includes a rotating unit and a floating unit. The top of the support column is provided with a groove, and the inner wall of the groove is provided with a wave-shaped groove. The rotating unit is disposed at the bottom of the groove, and the floating unit is sleeved on the outer wall of the rotating unit. The floating unit is slidably connected to the wave-shaped groove, and the tops of both the rotating unit and the floating unit are rotatably connected to the broadcasting module.

[0006] The rotating unit drives the floating unit to rotate, while the floating unit floats up and down vertically under the limiting action of the wave groove. The two actions combine to make the top broadcast module rotate horizontally and float vertically at the same time, increasing the sound coverage area.

[0007] Preferably, the rotating unit includes a servo motor, the output end of the servo motor is fixedly connected to a rotating column, sliding blocks are fixedly connected to both sides of the rotating column, a mounting bracket is fixedly connected to the top of the rotating column, and a connecting shaft is fixedly connected above the mounting bracket.

[0008] Preferably, the floating unit includes a sleeve, the rotating column passes through the sleeve and extends to both ends, the inner wall of the sleeve is provided with a sliding groove, the sliding blocks on both sides of the rotating column are slidably connected to the sliding groove, a control rod is fixedly connected to the lower part of the sleeve, and a fixed support is fixedly connected to the upper part of the sleeve.

[0009] Preferably, a fixing block is fixedly connected in the middle of the fixing support, and a push rod is fixedly connected to the outer wall of the fixing block.

[0010] Preferably, the broadcasting module includes a placement frame, a power distribution box and a solar panel are fixedly connected to the top of the placement frame, a telescopic cable is fixedly connected to the top of the power distribution box, a broadcasting device is fixedly connected to the end of the telescopic cable away from the power distribution box, the tail of the broadcasting device is rotatably connected to a connecting shaft, and the end of the broadcasting device is located above the push rod.

[0011] Preferably, a slide rail is fixedly connected to the bottom of the loudspeaker.

[0012] Preferably, the placement frame is fixedly connected to the outer wall of the support column, and the end of the push rod away from the fixed block is rotatably connected to a connecting shaft, which is inserted into the slide rail.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model constructs a dynamic coverage mechanism in both horizontal and vertical directions through the coordinated linkage of a rotating unit and a floating unit, completely changing the traditional single-coverage mode of emergency broadcasting. The servo motor in the rotating unit drives the rotating column to rotate stably, and the linked loudspeaker achieves 360° rotation, significantly improving the horizontal coverage range compared to traditional broadcasting and avoiding blind spots in a single direction.

[0015] 2. As the sleeve of the floating unit rotates with the rotating column, it periodically floats up and down due to the control rod sliding within the wave groove. This, in turn, pushes the loudspeaker to swing up and down via a push rod, filling the vertical coverage gap in traditional broadcasting and covering people in different elevations. This device is suitable for joint emergency response needs, providing a wide sound propagation coverage area. A single unit can achieve large-scale three-dimensional coverage without the need for multiple units to be spliced ​​together, reducing the number of equipment to be transported and installed, and meeting the requirements for rapid emergency response.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-3 The device shown is a joint emergency voice broadcasting device, including a support column 1, an adjustment mechanism 2, and a broadcasting module 3. The adjustment mechanism 2 includes a rotating unit 21 and a floating unit 22. The top of the support column 1 has a groove 11, and the inner wall of the groove 11 has a wave groove 12. The rotating unit 21 is located at the bottom of the groove 11, and the floating unit 22 is sleeved on the outer wall of the rotating unit 21. The floating unit 22 is slidably connected to the wave groove 12. The tops of the rotating unit 21 and the floating unit 22 are rotatably connected to the broadcasting module 3. The rotating unit 21 drives the floating unit 22 to rotate, and at the same time, the floating unit 22 floats up and down in the vertical direction under the limiting action of the wave groove 12. The two actions are combined, so that the broadcasting module 3 at the top of it can rotate in the horizontal direction and float in the vertical direction at the same time, increasing the sound coverage area.

[0026] like Figures 1-5 As shown, as a technical optimization of this utility model, the rotating unit 21 includes a servo motor 211, the output end of the servo motor 211 is fixedly connected to a rotating column 212, sliding blocks 213 are fixedly connected to both sides of the rotating column 212, a mounting bracket 214 is fixedly connected to the top of the rotating column 212, and a connecting shaft 215 is fixedly connected above the mounting bracket 214. The servo motor 211 drives the rotating column 212 to rotate stably, and the broadcast module 3 is linked to achieve 360° rotation. The horizontal coverage range is greatly improved compared with traditional broadcasting, avoiding blind spots in a single direction.

[0027] like Figures 3-6 As shown, as a technical optimization of this utility model, the floating unit 22 includes a sleeve 221, a rotating column 212 that passes through the sleeve 221 and extends to both ends, a groove 222 is provided on the inner wall of the sleeve 221, sliding blocks 213 on both sides of the rotating column 212 are slidably connected to the groove 222, a control rod 223 is fixedly connected to the lower part of the sleeve 221, a fixed support 224 is fixedly connected to the upper part of the sleeve 221, a fixed block 225 is fixedly connected in the middle of the fixed support 224, and a push rod 226 is fixedly connected to the outer wall of the fixed block 225. When the sleeve 221 rotates with the rotating column 212, it floats up and down periodically because the control rod 223 slides in the wave groove 12. The push rod 226 pushes the broadcast module 3 to swing up and down, filling the problem of the vertical coverage gap of traditional broadcasting, and can cover people in different areas.

[0028] like Figures 4-7 As shown, as a technical optimization of this utility model, the broadcast module 3 includes a placement frame 31. A distribution box 32 and a solar panel 33 are fixedly connected to the top of the placement frame 31. A telescopic cable 34 is fixedly connected to the top of the distribution box 32. A microphone 35 is fixedly connected to the end of the telescopic cable 34 away from the distribution box 32. The tail of the microphone 35 is rotatably connected to the connecting shaft 215. The end of the microphone 35 is above the push rod 226. A slide rail 36 is fixedly connected to the bottom of the microphone 35. The placement frame 31 is fixedly connected to the outer wall of the support column 1. A connecting shaft is rotatably connected to the end of the push rod 226 away from the fixed block 225. The connecting shaft is inserted into the slide rail 36. Under the combined action of the rotating unit 21 and the floating unit 22, the broadcast module 3 can rotate horizontally and float vertically at the same time, effectively increasing the sound coverage area.

[0029] In use, the servo motor 211 is started, which drives the rotating column 212 to rotate. The rotating column 212 drives the floating unit 22 and the loudspeaker 35 to rotate. While rotating, the floating unit 22 floats up and down along the outer wall of the rotating column 212 due to the limiting effect of the wave groove 12. Then, through the push rod 226 at the top, the loudspeaker 35 is driven to rotate 360° horizontally and swing vertically, thereby expanding the effective coverage of the sound.

[0030] Meanwhile, the servo motor 211 of the rotating unit 21 undergoes circuit modification, replacing the original potentiometer with two matching resistors, enabling it to perform 360° reciprocating rotation, thereby preventing the telescopic cable 34 from breaking due to excessive winding during rotation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
