Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a highway sound barrier with a wind-resistant structure. Background Art

[0002] In order to reduce the impact of railway noise, sound barriers are usually set up in places where residents live to cut off the propagation path of noise. The investment in sound barrier projects is appropriate and the sound insulation effect is good. It has become an important measure to control traffic noise pollution. The existing sound barriers have a simple structure, consisting of only a sound insulation screen and a support frame, and have weak wind resistance. When a train comes, the strong wind will blow down the sound barrier, making it unable to play a sound insulation effect.

[0003] According to the search, Chinese patent literature, announcement number: CN215482426U, discloses a railway sound barrier that is resistant to being blown down by the wind. The utility model provides a railway sound barrier that is resistant to being blown down by the wind. When the sound insulation screen is blown by the wind, it can be rotated backward by a certain angle, and the buffer spring plays a supporting and buffering role, thereby protecting the sound insulation screen and preventing the sound insulation screen from being bent and overturned by being directly impacted by the wind, thereby improving the wind resistance effect of the sound insulation screen.

[0004] However, the above technology still has some shortcomings. Although the above existing technology can resist strong wind impact to a certain extent, the wind direction is single. If strong wind blows from other directions, the device cannot resist it. In addition, it occupies a large space and fragile components are exposed, which reduces the service life. Utility Model Content

[0005] 1. Technical issues to be solved

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highway sound barrier with a wind-resistant structure, comprising a noise reduction barrier, a top cover is installed and connected to the outer top surface of the noise reduction barrier, a sound-absorbing hole is opened on the noise reduction barrier, a support plate is installed and connected to one side of the outer surface of the noise reduction barrier, a base is installed and fixed at the end of the support plate away from the noise reduction barrier, mounting strips are fixedly connected to both sides of the outer surface of the base, a wind resistance block is installed and connected to one side of the outer surface of the noise reduction barrier, sound-absorbing cotton is installed and connected to one side of the outer surface of the noise reduction barrier, a pressing plate is connected to one side of the outer surface of the sound-absorbing cotton, and a connecting rod is fixedly connected to one side of the outer surface of the pressing plate.

[0009] Preferably, a card slot is provided on the outer top surface of the noise reduction barrier, and a protruding block is provided on one side of the outer surface of the top cover, and the protruding block is embedded in the card slot.

[0010] Through the above technical solution, in order to achieve the purpose of wind protection, the top cover is provided with protruding blocks of the same width on both sides. The protruding blocks are embedded in the slots from the sides so that they are firmly fixed on the noise reduction barrier and cannot be moved unless they are disassembled manually.

[0011] Preferably, the noise reduction barrier is installed on the outer top surface of the base, and the pressing plates are symmetrically arranged.

[0012] Through the above technical scheme, sound-absorbing holes and sound-absorbing cotton are provided on the noise reduction barrier. The sound-absorbing holes have a wide absorption bandwidth and are resistant to high temperature, fire and moisture, have low resistance and long service life. The holes can allow sound waves to rebound multiple times to weaken the energy of the sound waves. Sound-absorbing cotton is also provided on the back of the sound-absorbing holes to absorb the weakened sound waves. It has a high sound absorption rate for various noises and outstanding sound insulation performance. The pressing plate tightly fixes the sound-absorbing cotton on the inside of the noise reduction barrier. The connecting rod provides relative support force, which also assists the windproof function of the device.

[0013] Preferably, a gravity pier is embedded inside the base, and the support plates are symmetrically arranged on both sides of the noise reduction barrier.

[0014] Through the above technical scheme, the gravity pier is the core windproof device of this device. It relies on its own gravity to suppress the base and all components fixed on the outer top surface of the base, plays a stabilizing role and is also the internal core supporting component, so that the noise reduction barrier can be firmly stabilized when encountering strong winds. The angle setting of the support plate forms an isosceles triangle. The isosceles triangle can be evenly stressed on both sides, and has strong stability in resisting strong winds. The interior is stabilized by the gravity pier and the exterior is strengthened by the support plate.

[0015] Preferably, a hook is installed and connected on one side of the outer surface of the base, and a hook lock is installed and connected on the side of the outer surface of the base away from the hook.

[0016] Through the above technical solution, the design of the left hook and the right hook lock allows the two groups of the device to be connected to each other. When encountering strong winds, the two groups of noise reduction barriers cannot be disconnected, and they can leverage each other to increase firmness.

[0017] Preferably, a weather vane is installed and connected to the outer top surface of the top cover, the installation strip is threadedly connected by a heavy-duty threaded rod, and the wind resistance blocks are symmetrically arranged.

[0018] Through the above technical solution, the weather vane can indicate the wind direction. When the wind blows, the end that produces greater resistance to air flow will rotate along the wind to display the wind direction. The base is fixed to the ground or a fixed point by a heavy threaded rod to increase the adhesion of the device to other solids, and the wind resistance block can greatly reduce the wind resistance of the device.

[0019] Compared with the prior art, the utility model provides a highway sound barrier with a wind-resistant structure, which has the following beneficial effects:

[0020] 1. In order to achieve the purpose of windproof, the utility model has protruding blocks of the same width on both sides of the top cover. The protruding blocks are embedded in the card slots from the sides to firmly fix them on the noise reduction barrier. Unless they are disassembled manually, they cannot be moved. Sound-absorbing holes and sound-absorbing cotton are provided on the noise reduction barrier. The sound-absorbing holes have the advantages of wide absorption bandwidth, high temperature resistance, fire resistance, moisture resistance, small resistance loss and long service life. The holes can allow sound waves to rebound multiple times to weaken the energy of the sound waves. Sound-absorbing cotton is also provided on the back of the sound-absorbing holes to absorb the weakened sound waves. It has a high sound absorption rate for various noises and outstanding sound insulation performance. The pressing plate tightly fixes the sound-absorbing cotton on the inside of the noise reduction barrier. The connecting rod provides relative support force, which also plays an auxiliary role in the windproof function of the device.

[0021] 2. The utility model uses the gravity pier as the core windproof device of the device, which relies on its own gravity to suppress the base and all components fixed on the top surface of the base, plays a stabilizing role and is also the internal core supporting component, so that the noise reduction barrier can be firmly stabilized when encountering strong winds. The angle setting of the support plate constitutes an isosceles triangle. The isosceles triangle can be evenly stressed on both sides, and has strong stability for resisting strong winds. The interior is stabilized by the gravity pier and the exterior is reinforced by the support plate. The design of the left hook and the right hook lock allows two groups of the device to be connected to each other. When encountering strong winds, the two groups of noise reduction barriers cannot be disconnected, and they borrow force from each other to increase firmness. The weather vane can indicate the wind direction. When the wind blows, the end that produces greater resistance to air flow will rotate downwind to display the wind direction.
