Description

Technical Field

[0001] This utility model relates to the field of track channel technology, specifically to a track channel audio and electrical protection device. Background Technology

[0002] The track tunnel audio and power protection device is a comprehensive system designed specifically for rail transit tunnels (such as subway tunnels, railway station passages, and light rail lines) to ensure the quality of audio communication and the stability and security of power supply within these tunnels.

[0003] However, the existing track channel audio and electrical protection devices have external microphones that are not dustproof, which makes it easy for dust to enter the microphones, resulting in unclear sound. Furthermore, when the microphones do not capture clear sound from below, the distance between the microphones and the sound source cannot be adjusted, which is inconvenient. Therefore, we propose a track channel audio and electrical protection device. Utility Model Content

[0004] The purpose of this invention is to provide a sound and electrical protection device for track channels.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a track channel audio-visual protection device, comprising an audio-visual protection device body, a control device disposed on the inner side of the audio-visual protection device body, a lifting plate installed at the lower end of the audio-visual protection device body, a microphone disposed at the lower end of the lifting plate, spring boxes installed on both sides of the lifting plate, sliders installed on the inner side of each spring box, clamping plates installed on the outer side of each slider, handles installed on the outer side of each clamping plate, side plates installed on the outer side of each spring box, an electric push rod disposed at the upper end of each side plate, a dustproof box installed on the inner side of the lifting plate, and a plug installed on the inner side of the clamping plate.

[0006] Preferably, the inner side of each slider is elastically connected to a spring, and the spring is located inside the spring box.

[0007] Preferably, the insertion post passes through the lifting plate and the dustproof box.

[0008] Preferably, a backup battery is fixedly connected to the inner side of the main body of the audio-visual protection device, and the backup battery is electrically connected to the control equipment.

[0009] Preferably, an installation plate is installed on the upper end of the main body of the audio-visual protection device, a sliding plate is installed on the upper end of the installation plate, a sliding box is installed on the outer side of the sliding plate, a top plate is provided on the upper end of the sliding box, a motor is provided on the lower end of the top plate, a gear is installed on the lower end of the motor, a spiral cylinder is meshed on the outer side of the gear, and a spiral column is installed on the inner side of the spiral cylinder.

[0010] Preferably, the outer side of the mounting plate is threaded with a first bolt, and the first bolt passes through the mounting plate and the body of the audio-visual protection device.

[0011] Preferably, a second bolt is provided through each of the four corners at the lower end of the top plate.

[0012] By adopting the above technical solution, the electric push rod is activated by the remote control device. The electric push rod, in conjunction with the side plate, pushes the lifting plate downward, thereby moving the microphone inside the lifting plate together. This brings the microphone closer to the lower position, allowing it to transmit the sound from below more clearly to the control device. Furthermore, the dustproof box protects the microphone from dust without affecting it. Then, by pulling the clamping plate with the help of springs, sliders, and pins, the pins can be quickly installed and removed for easy cleaning. This allows the height of the microphone in the track channel audio-visual protection device to be adjusted, bringing the microphone closer to the sound source and making the collected sound clearer, thus improving the accuracy of sound recording in the track channel audio-visual protection device.

[0013] By adopting the above technical solution, the top plate is installed into the ceiling at a corresponding depth according to the overall height. Then, the motor is started, and the motor, in cooperation with the gears and the spiral cylinder, drives the spiral column to move upward. When the spiral column moves, it will drive the sound and electrical protection device body to rise together. When the sliding box contacts the upper end of the sound and electrical protection device body, it stops, and the sound and electrical protection device body will be submerged in the ceiling, so that the sound and electrical protection device body is protected by the ceiling on all sides. Conversely, it will descend. The cooperation of the mounting plate, sliding plate and sliding box makes the lifting and lowering of the sound and electrical protection device body more stable. Furthermore, the meshing connection between the gears and the spiral cylinder prevents the spiral cylinder from slipping, so that the sound and electrical protection device body in the track channel can be completely submerged in the ceiling for protection, thereby improving the safety of the sound and electrical protection device body.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4 This utility model provides a technical solution: a track channel audio and electrical protection device, including an audio and electrical protection device body 1, a control device 2 is provided on the inner side of the audio and electrical protection device body 1, a lifting plate 4 is installed at the lower end of the audio and electrical protection device body 1, a microphone 5 is provided at the lower end of the lifting plate 4, spring boxes 6 are installed on both sides of the lifting plate 4, sliders 7 are installed on the inner side of the spring boxes 6, clamping plates 9 are installed on the outer side of the sliders 7, handles 10 are installed on the outer side of the clamping plates 9, side plates 11 are installed on the outer side of the spring boxes 6, an electric push rod 12 is provided at the upper end of the side plates 11, a dustproof box 13 is installed on the inner side of the lifting plate 4, and a plug 14 is installed on the inner side of the clamping plate 9.

[0022] The inner side of the slider 7 is elastically connected to a spring 8, and the spring 8 is located inside the spring box 6.

[0023] The insertion post 14 passes through the lifting plate 4 and the dustproof box 13.

[0024] A backup battery 3 is fixedly connected to the inner side of the main body 1 of the audio-visual protection device, and the backup battery 3 is electrically connected to the control device 2.

[0025] In use, when an argument occurs below the microphone 5 and the microphone 5's sound pickup is unclear, the user can remotely activate the electric push rod 12 via the control device 2. This push rod 12 lowers the side plate 11. As the side plate 11 descends, it pushes the lifting plate 4 downwards via the spring box 6. The microphone 5, connected to the lifting plate 4, moves along with the lifting plate 4, bringing the microphone 5 closer to the sound source. This closer proximity allows the microphone 5 to clearly transmit the sound from below to the control device 2 for collection. The dustproof box 13 then blocks external dust, preventing the microphone 5 from being affected by dust. When there is a lot of dust on the surface of the dustproof box 13... When the handle 10 is pulled, the clamping plate 9 moves outward. As the clamping plate 9 moves outward, it stretches the spring 8 through the slider 7. At the same time, the clamping plate 9 pulls out the insertion post 14, causing the insertion post 14 to lose its fixation to the dustproof box 13. Then, the dustproof box 13 is disassembled, cleaned, and then put back into its original position. Then, the handle 10 is released, and the clamping plate 9, under the elasticity of the spring 8, inserts the insertion post 14 into the dustproof box 13, thus completing the fixation. This allows the height of the microphone 5 to be adjusted by the track channel audio-visual protection device, so that the microphone 5 can be closer to the sound source, making the collected sound clearer and improving the accuracy of sound recording by the track channel audio-visual protection device.

[0026] Example 2:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a track channel audio and electrical protection device, wherein an installation plate 15 is installed on the upper end of the main body 1 of the audio and electrical protection device, a sliding plate 17 is installed on the upper end of the installation plate 15, a sliding box 18 is installed on the outer side of the sliding plate 17, a top plate 19 is provided on the upper end of the sliding box 18, a motor 20 is provided on the lower end of the top plate 19, a gear 21 is installed on the lower end of the motor 20, a spiral cylinder 22 is meshed on the outer side of the gear 21, and a spiral column 23 is installed on the inner side of the spiral cylinder 22.

[0028] The outer side of the mounting plate 15 is threaded with a first bolt 16, and the first bolt 16 passes through the mounting plate 15 and the main body 1 of the audio-visual protection device.

[0029] Second bolts 24 are installed through the four corners of the lower end of the top plate 19.

[0030] Specifically, the top plate 19 is installed into the ceiling at the corresponding depth according to the overall height using the second bolt 24. Then, the motor 20 is started, causing the motor 20 to drive the gear 21 to rotate. When the gear 21 rotates, the spiral cylinder 22, which meshes with the gear 21, will rotate along with the gear 21. When the spiral cylinder 22 rotates, it will drive the internal spiral column 23 to move upward. When the spiral column 23 moves, it will drive the sound and electrical protection device body 1 to rise together. At the same time, when the sound and electrical protection device body 1 rises, it will push the mounting plate 15 to rise. Then, the mounting plate 15 will push the sliding plate 17 to slide inside the sliding box 18. When the sliding box 18 contacts the upper end of the sound and electrical protection device body 1, it will stop. At this time, the sound and electrical protection device body 1 will be submerged in the ceiling, so that the sound and electrical protection device body 1 is protected by the ceiling on all sides, thus completing the installation. Conversely, it will descend, so that the spiral cylinder 22 will not slip, and the sound and electrical protection device of the track channel can be completely submerged in the ceiling for protection, thereby improving the safety of the sound and electrical protection device body 1.
