Detailed implementation manners

[0024] The following describes the implementation manners of the present utility model with reference to the drawings.

[0025] Embodiment 1: A noise reduction fence for highway construction, as Figures 1-4 shown, includes a fence 1, a noise reduction plate 2, a protective plate 3, a filter screen 4, and a replacement mechanism. Noise reduction plates 2 are clamped on both left and right sides of the fence 1. Protective plates 3 are rotatably connected to both left and right sides of the fence 1. A filter screen 4 is fixedly connected to the middle of the protective plate 3. A replacement mechanism is provided on the protective plate 3.

[0026] As Figure 1 shown, handles are fixedly connected to the mutually remote sides of two of the protective plates 3.

[0027] As Figures 1-4 shown, the replacement mechanism includes a first gear 5, a fixed block 6, a guide rod 7, a clamping block 8, a spring 9 and a limiting block 10. On the mutually approaching sides of the left and right protective plates 3, a first gear 5 is fixedly connected to each. The left and right first gears 5 mesh with each other. On the upper parts of the mutually remote sides of the two protective plates 3, a fixed block 6 is fixedly connected to each. On the left and right sides of the top of the fence 1, a guide rod 7 is fixedly connected to each. A clamping block 8 is slidably connected to the outside of the guide rod 7. A spring 9 is fixedly connected between the clamping block 8 and the guide rod 7. The clamping block 8 is in extrusion fit with the adjacent fixed block 6. On the left and right sides of the top of the fence 1, a limiting block 10 is fixedly connected to each. The clamping block 8 is slidably connected to the adjacent limiting block 10.

[0028] When the noise reduction plate 2 becomes aged or corroded due to long-term use and needs to be replaced, the corresponding protective plate 3 and filter screen 4 can be rotated forward and opened through the handle on one side. The rotation of the protective plate 3 on one side will drive the corresponding first gear 5 to rotate and make the first gear 5 and the protective plate 3 on the other side rotate synchronously, so that people can quickly replace the noise reduction plates 2 on both sides. When the protective plate 3 is rotated forward and opened, the fixed block 6 will also rotate accordingly and squeeze the clamping block 8, causing the clamping block 8 to move upward, and the spring 9 will be compressed immediately. When the fixed block 6 continues to rotate and separates from the clamping block 8, the clamping block 8 will move downward and reset under the action of the spring 9 and its own gravity, thereby releasing the fixation of the protective plate 3. After replacing the noise reduction plate 2, people can rotate the protective plate 3, filter screen 4 and fixed block 6 on one side in the reverse direction to reset. The protective plate 3, filter screen 4 and fixed block 6 on the other side will also rotate in the reverse direction and reset under the action of the first gear 5. During this period, the fixed block 6 will first squeeze the clamping block 8 and make it move upward. After the fixed block 6 rotates and resets, the clamping block 8 will move downward and reset under the action of the spring 9 and its own gravity and clamp the fixed block 6, thereby limiting and fixing the protective plates 3 and filter screens 4 on both sides.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figure 5 and Figure 6As shown in the figure, it also includes an installation frame 11, a card seat 12, a winding wheel 13, a spring 1301, a sound-absorbing cloth 14, a first magnet 15, a first electric guide rod 16, a sliding plate 17, a second magnet 18 and a protective shell 19. Installation frames 11 are fixedly connected to the left and right sides of the top of the fence 1. A card seat 12 is slidably connected to the top of the installation frame 11. A winding wheel 13 is rotatably connected to the middle of the card seat 12. A spring 1301 is fixedly connected between the winding wheel 13 and the card seat 12. A sound-absorbing cloth 14 is wound around the outside of the winding wheel 13. The other end of the sound-absorbing cloth 14 is fixedly connected to a first magnet 15. A group of first electric guide rods 16 are fixedly connected to the left and right sides of the fence 1, and each group includes two left and right first electric guide rods 16. A sliding plate 17 is slidably connected between the left and right first electric guide rods 16 in a group. A second magnet 18 is fixedly connected to the middle of the sliding plate 17. The first magnet 15 is adsorbed and matched with the adjacent second magnet 18. A protective shell 19 is snap-connected to the top of the card seat 12.

[0030] When the construction noise is too loud and further noise reduction is required, the first electric guide rod 16 can be started to drive the sliding plate 17 and the second magnet 18 to move downward. Since the first magnet 15 and the second magnet 18 are adsorbed to each other, the first magnet 15 will also move downward and pull the sound-absorbing cloth 14 downward. The winding wheel 13 will then rotate, and the spring 1301 will also deform accordingly. In this way, not only can the noise reduction board 2 be blocked and protected by the sound-absorbing cloth 14 to prevent the noise reduction board 2 from being quickly corroded and aged by the external environment, thereby extending the service life of the noise reduction board 2, but also the overall noise reduction effect can be improved. When not in use, the first electric guide rod 16 can be used to drive the sliding plate 17, the second magnet 18 and the first magnet 15 to move upward and reset. At this time, the winding wheel 13 will rotate reversely and reset under the action of the spring 1301 and rewind the sound-absorbing cloth 14. If the sound-absorbing cloth 14 is aged or corroded, the components such as the card seat 12, the winding wheel 13 and the sound-absorbing cloth 14 can be directly removed from the installation frame 11 and replaced, which is very simple and convenient.

[0031] As Figure 7 and Figure 8 shown in the figure, it also includes a second electric guide rod 20, a slider 21, a cleaning brush 22, a second gear 23 and a rack 24. Second electric guide rods 20 are fixedly connected to the upper and lower parts of the front side of the protective plate 3. A slider 21 is slidably connected to the outside of the second electric guide rod 20. A cleaning brush 22 is rotatably connected between the upper and lower sliders 21. The cleaning brush 22 is in contact and cooperation with the filter screen 4. Second gears 23 are fixedly connected to the upper and lower sides of the cleaning brush 22. A rack 24 is fixedly connected to the front side of the second electric guide rod 20. The second gears 23 are meshed with the adjacent racks 24.

[0032] As Figure 7 and Figure 8 shown in the figure, the cleaning brush 22 is made of polyester fiber material.

[0033] When there is a lot of dust and impurities accumulated on the filter screen 4 and it causes blockage, the second electric guide rod 20 can be activated, driving the slider 21, the cleaning brush 22 and the second gear 23 to move left and right. During this period, the second gear 23 will engage with the rack 24, so that the cleaning brush 22 and the second gear 23 will continuously rotate while moving left and right, thereby cleaning the dust and impurities accumulated on the filter screen 4, preventing the dust and impurities from passing through the filter screen 4 and blocking the pores of the noise reduction plate 2, and also preventing the accumulated impurities from causing chemical corrosion to the noise reduction plate 2, resulting in a reduction in the noise reduction effect.

[0034] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
