Description

Technical Field

[0001] This utility model relates to the field of tunnel risk management technology, and in particular to a tunnel risk on-site management equipment. Background Technology

[0002] Tunnel risk site control equipment is a type of audio equipment used in emergency management. It is primarily used to transmit on-site commands, warnings, or important information, ensuring that personnel inside the tunnel can receive safety instructions or emergency notifications in a timely manner.

[0003] The existing device has the drawback of not being able to adjust the tilt angle. The enclosed spatial structure of the tunnel easily leads to sound wave reflection. If the device cannot tilt downwards, sound will frequently collide and reflect with the top and side walls, creating echoes. In this situation, important information such as rescue instructions and safety warnings issued by the on-site command will become unclear due to the mixed sound. Utility Model Content

[0021] 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 scope of protection of the present utility model.

[0022] This utility model provides a tunnel risk on-site management and control equipment, such as... Figure 1 and Figure 2 As shown, the device includes a directional sound wave horn device 1, a vertical plate 2, a support frame 3, a slider 4, a connecting rod 5, and a clamping assembly 6. The vertical plate 2 is provided on one side of the directional sound wave horn device 1. The support frame 3 is fixedly connected to the bottom of the side of the vertical plate 2 closest to the directional sound wave horn device 1. The slider 4 is provided above the support frame 3 and is fixed to the vertical plate 2. The directional sound wave horn device 1 is rotatably connected to the free end of the support frame 3. One end of the connecting rod 5 is rotatably connected to the directional sound wave horn device 1, and the other end of the connecting rod 5 is slidably connected to the slider 4. The clamping assembly 6 is provided on the side of the vertical plate 2 away from the directional sound wave horn device 1.

[0023] like Figure 1 and Figure 4 As shown, an outer cover 11 is provided on the outside of the directional sound wave horn device 1. The outer cover 11 not only protects the internal horn device from corrosion by environmental factors such as dust and water vapor in the tunnel, but also enhances the directional propagation effect of sound to a certain extent. Rotary cylinders 111 are fixedly connected to the bottom of both sides of the outer cover 11. The interior of the rotary cylinders 111 has annular grooves 1111. A rotating seat 112 is fixedly connected to the end face of the outer cover 11 near the vertical plate 2. Inner extension columns 31 are fixedly connected to both sides of the free end of the support frame 3. A rotating ring 32 is fixedly connected to the outer periphery of the inner extension column 31, and the rotating ring 32 is rotatably connected in the annular groove 1111. Figure 2 and Figure 3As shown, two sets of slide bars 4 are symmetrically arranged, with a gap between the two sets of slide bars 4, and the connecting rod 5 is located in the gap. One end of the connecting rod 5 is provided with a fixing screw 51, and the other end of the connecting rod 5 is provided with a fixing screw 52. One end of the connecting rod 5 is rotatably connected to the inside of the rotating base 112 through the fixing screw 51. A transverse groove 41 is opened through the side of the slide bar 4, and the other end of the connecting rod 5 is slidably connected in the transverse groove 41 through the fixing screw 52.

[0024] Because the directional sound wave horn device 1 and the free end of the support frame 3 are rotatably connected through the cooperation of the rotating cylinder 111 and the inner extension column 31, the annular groove 1111 inside the rotating cylinder 111 at the bottom of both sides of the outer cover 11 is rotatably connected to the rotating ring 32 on the outer periphery of the inner extension column 31 on both sides of the free end of the support frame 3, so that the directional sound wave horn device 1 can rotate around the connection point as the axis. At the same time, one end of the connecting rod 5 is rotatably connected to the inside of the rotating seat 112 through the fixing screw 1 51, and the other end slides in the transverse groove 41 of the slide bar 4 through the fixing screw 2 52. When the directional sound wave horn device 1 rotates, the connecting rod 5 slides in the transverse groove 41, which plays a role in auxiliary support and limiting the rotation angle, ensuring that the directional sound wave horn device 1 can be stably adjusted to the required angle.

[0025] like Figure 3 and Figure 5 As shown, the clamping assembly 6 includes an upper clamping plate 61, a lower clamping plate 62, and a long screw 63. The upper clamping plate 61 is fixed on the upright plate 2. A vertical groove 21 is provided on the side of the upright plate 2. The lower clamping plate 62 is located below the upper clamping plate 61. The lower clamping plate 62 is slidably connected to the upright plate 2 through the vertical groove 21. An upper extension plate 611 is fixedly connected to the free end of the upper clamping plate 61, and a lower extension plate 621 is fixedly connected to the free end of the lower clamping plate 62. The long screw 63 is disposed between the upper clamping plate 61 and the lower clamping plate 62.

[0026] A crossbeam is fixed to the inner wall of the tunnel. The vertical plate 2 is then placed close to the crossbeam, positioning the crossbeam between the upper clamping plate 61 and the lower clamping plate 62. At this point, the upper clamping plate 61 is fixed to the vertical plate 2, while the lower clamping plate 62 can be slidably adjusted via the vertical groove 21 on the side of the vertical plate 2. Depending on the thickness and installation position of the crossbeam, the lower clamping plate 62 is pushed up and down within the vertical groove 21, causing the upper and lower clamping plates 61 and 62 to initially conform to the upper and lower surfaces of the crossbeam, ensuring they are parallel and in close contact with the crossbeam. Next, the long screw 63 is sequentially passed through the upper extension plate 611 at the free end of the upper clamping plate 61, the crossbeam, and the lower extension plate 621 at the free end of the lower clamping plate 62. During insertion, the long screw 63 is ensured to be perpendicular to the upper and lower extension plates 611 and 621 to prevent tilting and uneven force distribution. After inserting the long screw 63, a matching nut is screwed onto the end of the long screw 63. As the nuts are tightened, the long screw 63 generates tension, pulling the lower extension plate 621 upward, which in turn causes the lower clamping plate 62 to gradually move closer to the upper clamping plate 61. During this process, because the lower clamping plate 62 slides in the vertical groove 21, it can adapt to the unevenness of the crossbeam surface and always maintain a tight fit with the crossbeam. Continue to tighten the nuts until the upper clamping plate 61 and the lower clamping plate 62 firmly clamp the crossbeam, ensuring that the equipment will not loosen or slip in the complex construction or operation environment of the tunnel.

[0027] Using this utility model, such as Figure 1 and Figure 2 As shown, firstly, the crossbeam used for fixing the device is fixed at a suitable position on the tunnel sidewall. The positions of the upper clamping plate 61 and lower clamping plate 62 are adjusted using the long screw 63, clamping and fixing them to the crossbeam fixed on the tunnel sidewall, thus achieving stable installation of the device. Rotating the directional sound wave horn device 1 causes the fixing screw 52 on the connecting rod 5 to slide in the transverse groove 41. After the device is adjusted to a suitable tilt angle, the fixing screws 51 and 52 are tightened, fixing both ends of the connecting rod 5 to the inside of the rotating seat 112 and between the two sets of sliding strips 4, respectively, providing auxiliary support and limiting the rotation angle. This allows for timely and accurate transmission of risk warning information to personnel inside the tunnel, effectively improving the efficiency and effectiveness of tunnel risk management.

[0028] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
