Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, specifically to an environmentally friendly noise reduction device. Background Technology

[0002] Currently, with the increasing severity of highway traffic noise pollution, some countries are extensively using various forms of barriers to reduce traffic noise. Similarly, within buildings, if sound insulation requirements are not high, barriers can be used to separate workshops and offices. These commonly used noise reduction barriers, also known as sound barriers, are a common sound insulation facility. To block direct sound between the sound source and the receiver, a barrier is inserted between the source and the receiver, causing a significant additional attenuation of sound wave propagation, thereby reducing the noise impact within a certain area where the receiver is located.

[0003] Existing sound barriers are generally composed of support frames and sound insulation panels. The sound insulation panels are used to block and absorb noise, thereby reducing noise. However, due to certain deviations in the flatness of the road, there are gaps between the sound insulation panels and the ground, which reduces the efficiency of sound insulation and noise reduction.

[0004] According to the utility model disclosed in CN219364369U, a splicing noise reduction barrier is provided, including a noise reduction barrier and a connecting rod disposed between adjacent noise reduction barriers. The bottom of the connecting rod is fixedly connected to a base, and a fixed spike inserted into the ground is disposed through the upper end of the base. A lighting lamp is disposed at the upper end of the connecting rod. Multiple sets of rotating sleeves are rotatably connected to the outer side of the connecting rod through bearings. A connector is fixedly connected to the outer side of the rotating sleeve, and a locking block is fixedly connected to the outer side of the noise reduction barrier. A locking groove for locking and engaging the locking block is opened on the outer side of the connector. A reinforcement mechanism is detachably and fixedly installed at the bottom of the noise reduction barrier.

[0005] The spliced ​​noise reduction barrier described above suffers from the problem mentioned above, where the gaps between the sound insulation panel, connecting rod, and ground result in low sound insulation and noise reduction efficiency. Therefore, we need to propose an environmentally friendly noise reduction device. Utility Model Content

[0006] The purpose of this utility model is to provide an environmentally friendly noise reduction device. Through concave grooves on both sides of the support frame, the sound insulation board is inserted into the inner side of two adjacent sets of support frames, thereby achieving rapid installation of the sound barrier without any assembly gaps, improving noise reduction efficiency. Simultaneously, utilizing the sealing component at the bottom of the sound insulation board, the rubber sheet moves downwards under the action of a spring, causing the bottom of the rubber sheet to adhere and seal against the ground, thus achieving the effect of sealing gaps. Furthermore, the folding sealing plate is also made of rubber material, possessing elasticity to allow for vertical movement of the rubber sheet. At the same time, the folding sealing plate has a certain noise reduction effect, reducing the transmission of noise through the gap between the sound insulation board and the ground, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly noise reduction device, comprising a support frame, wherein concave grooves are provided on both sides of the support frame, and a set of sound insulation boards for noise reduction are inserted into the concave grooves on opposite sides of the two sets of support frames, and a sealing assembly for sealing is installed at the bottom of the sound insulation board; the sealing assembly includes a connecting plate fixedly installed at the bottom of the sound insulation board, and a set of folding sealing plates are fixedly installed on both sides of the bottom of the connecting plate, and a set of rubber plates is installed at the bottom of the two sets of folding sealing plates, and a cavity is formed between the connecting plate, the folding sealing plates, and the rubber plates, and several sets of springs are installed inside the cavity.

[0008] Preferably, one end of several sets of springs is connected to the bottom of the connecting plate, and the other end of several sets of springs is connected to the top of the rubber plate.

[0009] Preferably, the sound insulation panel includes a vacuum panel, and the inner cavity of the vacuum panel has a vacuum cavity for sound insulation.

[0010] Preferably, a reinforcing frame is installed on one side of the vacuum plate, and sound-absorbing cotton is filled in the groove inside the reinforcing frame.

[0011] Preferably, a protective plate for protecting the sound-absorbing cotton is installed on one side of the reinforcing frame, and a sound-absorbing groove is provided through one side of the protective plate.

[0012] Preferably, the top of the support frame has two sets of lock holes, and a set of rainproof plates to protect the sound insulation board is installed on the top of the two adjacent sets of support frames. Two sets of positioning rods are fixedly installed at the bottom of the rainproof plates, and one end of each of the two sets of positioning rods is respectively locked into a set of lock holes on the top of the two adjacent sets of support frames.

[0013] Preferably, a set of mounting plates is fixedly installed at the bottom of each support frame, and four sets of fixing rods are installed through the four corners of the mounting plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a sealing component, through the connection between the connecting plate, sealing rubber plate, spring, and rubber plate. Taking advantage of the stretchability of the folding sealing plate, when encountering uneven ground, the spring compresses the rubber plate downwards. The rubber plate also possesses a certain deformation capacity, allowing it to adhere and seal against the ground under the action of the spring, thus achieving the effect of sealing gaps. This avoids the situation where gaps exist between the moving sound insulation panel and the ground, which would reduce the efficiency of sound insulation and noise reduction, thereby improving the efficiency of noise reduction.

The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5This utility model provides an environmentally friendly noise reduction device, including a support frame 1. The support frame 1 has concave grooves 2 on both sides. A set of sound insulation panels 3 for noise reduction is inserted into the concave grooves 2 on opposite sides of the two sets of support frames 1. A sealing assembly 4 for sealing is installed at the bottom of the sound insulation panel 3. The sealing assembly 4 includes a connecting plate 41 fixedly installed at the bottom of the sound insulation panel 3. A set of folding sealing plates 42 are fixedly installed on both sides of the bottom of the connecting plate 41. A set of rubber plates 43 is installed at the bottom of the two sets of folding sealing plates 42. A cavity groove 44 is formed between the connecting plate 41, the folding sealing plates 42, and the rubber plates 43. Several sets of springs 45 are installed inside the cavity groove 44.

[0025] In use, the support frame 1 is installed in the designated position, and the sound insulation panel 3 is inserted into the inner side of the two adjacent sets of support frames 1 through the concave groove 2, thereby achieving the effect of rapid installation of the sound barrier without any assembly gaps, improving the efficiency of noise reduction. At the same time, with the sealing component 4 at the bottom of the sound insulation panel 3, the rubber plate 43 moves downward under the action of the spring 45, so that the bottom of the rubber plate 43 fits and seals with the ground, thereby achieving the effect of sealing the gap. The folding sealing plate 42 is also made of rubber material and has elasticity to meet the effect of the rubber plate 43 moving up and down. At the same time, the folding sealing plate 42 has a certain noise reduction effect, reducing the transmission of noise through the gap between the sound insulation panel 3 and the ground.

[0026] One end of several sets of springs 45 is connected to the bottom of the connecting plate 41, and the other end of several sets of springs 45 is connected to the top of the rubber plate 43. Through the connection relationship between the connecting plate 41, springs 45, and rubber plate 43, the effect of fixing the springs 45 is achieved. When the ground is uneven, each set of springs 45 will squeeze the rubber plate 43. The rubber plate 43 has a certain deformation capacity and can fit and seal with the ground under the action of the springs 45, thereby achieving the effect of sealing the gap.

[0027] The sound insulation panel 3 includes a vacuum panel 31. The inner cavity of the vacuum panel 31 is provided with a vacuum cavity for sound insulation. By utilizing the vacuum panel 31, the vacuum panel 31 effectively blocks sound using its own cavity groove 44, thereby improving the efficiency of noise reduction.

[0028] A reinforcing frame 32 is installed on one side of the vacuum plate 31. Sound-absorbing cotton 33 is filled in the groove inside the reinforcing frame 32. The reinforcing frame 32 strengthens the structure of the entire soundproof plate, and the sound-absorbing cotton 33 absorbs and blocks noise, further improving the noise reduction effect.

[0029] A protective plate 34 is installed on one side of the reinforcing frame 32 to protect the sound-absorbing cotton 33. A sound-absorbing groove 35 is opened through one side of the protective plate 34. The protective plate 34 is located on the side of the noise source. The sound insulation plate 3 emits part of the sound to reduce noise. At the same time, several sets of sound-absorbing grooves 35 are used to transmit the noise to the inside of the sound-absorbing cotton 33 for further noise reduction. The sound-absorbing grooves 35 are opened at an angle downward, which has the effect of rainwater backflow and prevents rainwater from entering the inside of the sound-absorbing cotton 33.

[0030] The top of the support frame 1 has two sets of locking holes 5. A set of rainproof plates 6 for protecting the sound insulation board 3 is installed on the top of the two adjacent sets of support frames 1. Two sets of positioning rods 7 are fixedly installed at the bottom of the rainproof plate 6. One end of the two sets of positioning rods 7 is respectively inserted into a set of locking holes 5 on the top of the two adjacent sets of support frames 1. The rainproof plate 6 is set at an angle to prevent rainwater from directly hitting the sound insulation board 3 and to avoid the sound insulation board 3 from being eroded by rainwater, which would reduce its service life. At the same time, the protective plate 34 can further reduce the transmission of noise.

[0031] A set of mounting plates 8 are fixedly installed at the bottom of each support frame 1. Four sets of fixing rods 9 are installed through the four corners of the mounting plates 8. The support frame 1 is fixedly installed through the connection between the support frame 1, the mounting plates 8 and the fixing rods 9.

[0032] In practical use, the mounting plate 8 of the support frame 1 is installed in the designated position through the fixing rod 9, thereby achieving the effect of fixed installation of the support frame 1. Then, the sound insulation board 3 is inserted into the concave groove 2 of the two adjacent sets of support frames 1, thus installing the solid sound insulation board 3. Then, the rainproof board 6 is installed on the top of the support frame 1 through the positioning rod 7. The rainproof board 6 plays a protective and fixing role for the sound insulation board 3, preventing the sound insulation board 3 from moving upward and also playing a rainproof role. The rubber plate 43 moves downward under the action of the spring 45, so that the bottom of the rubber plate 43 fits and seals with the ground, thereby achieving the effect of sealing the gap. The folding sealing plate 42 is also made of rubber material and has elasticity, which meets the effect of the rubber plate 43 moving up and down. At the same time, the folding sealing plate 42 has a certain noise reduction effect.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
