Description

Technical Field

[0001] This application relates to the technical field of photovoltaic and sound barrier integration, specifically a photovoltaic sound barrier heat dissipation backplate frame structure. Background Technology

[0002] With the rapid development of new energy technologies, photovoltaic power generation has become an important part of renewable energy. However, photovoltaic panels generate a lot of heat due to solar radiation during operation, which leads to temperature rise and reduces power generation efficiency. At present, sound barriers are widely used as traffic noise reduction facilities, but there are still technical bottlenecks in the integration of their structure with photovoltaic panels. In particular, how to effectively dissipate heat without increasing additional energy consumption has become a problem that needs to be solved.

[0003] Existing technologies have found that natural wind cooling relies on ambient wind power to dissipate heat from photovoltaic panels. Most existing sound barrier back panels are planar structures, which cannot effectively guide airflow, resulting in low heat dissipation efficiency on the back of the photovoltaic panels. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a photovoltaic sound barrier backplate frame structure with airflow guiding and heat dissipation characteristics. This structure has the advantages of forming vortices in the airflow through the airflow guide channels, enhancing the convective heat transfer effect, reducing temperature rise, and lowering operation and maintenance costs. It solves the problem that existing sound barrier backplates are mostly planar structures, which cannot effectively guide airflow and result in low heat dissipation efficiency on the back of the photovoltaic panel.

[0005] To achieve the above objectives, this application provides the following technical solution: a photovoltaic sound barrier heat dissipation backplate frame structure, including a mounting frame one, a backplate body fixedly mounted on the inner wall of the mounting frame one, and a backplate body with equidistantly arranged flow channels on the back of the backplate body. A mounting frame two is fixedly mounted on the upper surface of the mounting frame one, and the inner sidewall of the mounting frame two is fixedly connected to the outer surface of the backplate body. There are gaps between the upper and bottom surfaces of the backplate body and the inner walls of the mounting frame one and the mounting frame two. A photovoltaic panel body is provided on the inner wall of the mounting frame two, and there is a gap between the front of the backplate body and the back of the photovoltaic panel body.

[0006] The above scheme guides airflow, utilizes natural wind to enhance heat dissipation, and reduces the temperature rise of the photovoltaic panel. A backplate is installed on the inner wall of mounting frame one, with a guide channel on the back of the backplate. This longitudinal guide channel creates an internal vortex in the airflow. Mounting frame two is positioned on the upper surface of mounting frame one, and the backplate is fixed to mounting frame two. Since there is a certain distance between the upper and lower surfaces of the backplate and mounting frames one and two, and a gap between the front of the backplate and the back of the photovoltaic panel, when natural wind enters the gap between the backplate and the photovoltaic panel through the guide channel, the airflow forms a vortex, enhancing convective heat transfer and carrying away heat from the back of the photovoltaic panel, thus reducing temperature rise. The structure is simple, requires no additional energy consumption, and reduces operating and maintenance costs.

[0007] Furthermore, two sound barrier panels are fixedly installed on the inner wall of the mounting frame one, and each sound barrier panel has a sound-absorbing hole on its front side. A sound-absorbing layer is fixedly installed on the inner wall of the mounting frame one.

[0008] The above solution involves installing two sound barrier panels on the inner wall of mounting frame one. These panels are fixed together. Sound-absorbing holes are made on the front of the sound barrier panels. When sound waves propagate to the sound barrier panels, these holes allow the sound waves to smoothly enter the sound-absorbing material behind the sound barrier panels. Without these holes, most of the sound waves would be reflected by the sound barrier panels, with only a small amount able to enter the interior through the gap between the sound barrier panels and mounting frame one. A sound-absorbing layer is installed on the inner wall of mounting frame one. When sound travels to the rear through the sound-absorbing holes, the sound-absorbing layer can absorb the sound.

[0009] Furthermore, the sound-absorbing layer is made of centrifugal glass wool, and there is a gap between the back of the sound-absorbing layer and the front of the back panel body.

[0010] The above solution uses centrifugal glass wool as the material for the sound-absorbing layer. Centrifugal glass wool has a porous structure. When sound waves enter the sound-absorbing layer through the sound barrier panel, the centrifugal glass wool can absorb the sound into its internal pores. When the sound waves propagate in the fiber gaps and pores of the centrifugal glass wool, they will rub against the fibers and be continuously reflected in the pores. These processes will gradually convert sound energy into heat energy, thereby achieving the sound absorption effect. A certain gap is placed between the back of the sound-absorbing layer and the main body of the back panel to facilitate airflow.

[0011] Furthermore, a waterproof layer is provided on the front side of the sound-absorbing layer, and the waterproof layer is made of polyvinyl fluoride.

[0012] The above solution places the waterproof layer on the front of the sound-absorbing layer, and the waterproof layer is made of polyvinyl fluoride (PVC). This effectively blocks the intrusion of rainwater, dew, and other moisture, keeping the sound-absorbing material dry. The main function of the waterproof layer is to prevent moisture from entering the interior of the sound-absorbing layer behind it. PVC also has a certain degree of resistance, providing corrosion resistance. In addition, PVC has good UV resistance, absorbing and reflecting most ultraviolet rays, reducing UV damage to the sound-absorbing layer.

[0013] Furthermore, the inner bottom wall of the second mounting bracket is fixedly connected to two fixing blocks, and the inner bottom wall of the second mounting bracket is fixedly connected to two fixing blocks.

[0014] The above scheme involves installing fixing block one on the inner bottom wall of mounting frame two for a fixed connection, and simultaneously installing fixing block two on the inner bottom wall of mounting frame two for a fixed connection. This allows for the installation of fixing blocks one and two, which can limit the lower half of the photovoltaic panel body and achieve positioning installation.

[0015] Furthermore, a top plate is fixedly installed on the upper surface of the second mounting bracket, and two fixing blocks are fixedly connected to the inner sidewall of the second mounting bracket.

[0016] The above scheme involves placing the top plate on the upper surface of the mounting frame two and fixing it with bolts, allowing the top plate to be installed and removed. The fixing block three is installed on the inner side wall of the mounting frame two and set as a fixed connection to achieve the installation of the fixing block three.

[0017] Furthermore, a fixing bolt is fixedly installed on the inner wall of each fixing block three, and a fixing block four is fixedly installed on the outer surface of each fixing bolt.

[0018] With the above scheme, the fixing bolts are installed on the inner wall of the fixing block three, and the fixing block four is installed on the surface of the corresponding fixing bolts. Through the fixing block three, the fixing bolts and the fixing block four, the photovoltaic panel body can be clamped, so that the photovoltaic panel body can be fastened and installed.

[0019] Furthermore, a connecting rod is provided above the main body of the back plate, and the left and right ends of the connecting rod are fixedly connected to the outer surface of the corresponding fixing block four.

[0020] With the above solution, the connecting rod is placed above the main body of the back panel, and the left and right ends of the connecting rod are connected to the corresponding fixing block four respectively. After the fixing block four is installed by fixing bolts, the stability of the photovoltaic panel main body after installation can be improved by the connecting rod.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This photovoltaic sound barrier features a heat-dissipating backplate frame structure. It comprises a backplate main body, a flow channel, a second mounting frame, and a photovoltaic panel main body. The backplate main body is fixed to the inner wall of the first mounting frame, and a flow channel is formed on the back of the backplate main body. The second mounting frame is fixed to the upper surface of the first mounting frame, and the photovoltaic panel main body is then mounted thereon. Because there are gaps between the backplate main body and the first, second, and photovoltaic panels, natural wind can enter the gap between the backplate main body and the photovoltaic panel main body through the flow channel. The airflow forms vortices, enhancing the convective heat transfer effect, thereby removing heat from the back of the photovoltaic panel main body and reducing temperature rise. The structure is simple, requires no additional energy consumption, and reduces operating and maintenance costs. A waterproof layer protects the sound-absorbing layer, preventing water intrusion and reducing UV damage, thus extending the lifespan of the sound-absorbing layer. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 3 , Figure 4 and Figure 5This embodiment of a photovoltaic sound barrier heat dissipation backplate frame structure includes a mounting frame 1, a backplate body 2 fixedly mounted on the inner wall of the mounting frame 1, and a backplate body 2 with equidistantly arranged flow channels 3 on the back side of the backplate body 2. A mounting frame 4 is fixedly mounted on the upper surface of the mounting frame 1, and the inner side wall of the mounting frame 4 is fixedly connected to the outer surface of the backplate body 2. There are gaps between the upper and bottom surfaces of the backplate body 2 and the inner walls of the mounting frame 1 and the mounting frame 4. A photovoltaic panel body 5 is provided on the inner wall of the mounting frame 4, and there is a gap between the front side of the backplate body 2 and the back side of the photovoltaic panel body 5.

[0032] Please see Figure 1 , Figure 2 and Figure 4 Two sound barrier panels 6 are fixedly installed on the inner wall of the mounting frame 1. Each sound barrier panel 6 has sound-absorbing holes on its front side. A sound-absorbing layer 8 is fixedly installed on the inner wall of the mounting frame 1. The sound barrier panels 6 are installed on the inner wall of the mounting frame 1, and two sound barrier panels 6 are set up and fixed between the two sound barrier panels 6. By opening sound-absorbing holes on the front side of the sound barrier panels 6, when sound waves propagate to the sound barrier panels 6, the sound-absorbing holes allow the sound waves to smoothly enter the sound-absorbing material behind the sound barrier panels 6. Without these sound-absorbing holes, most of the sound waves will be reflected by the sound barrier panels 6, and only a small amount can enter the interior through the gap between the sound barrier panels 6 and the mounting frame 1. The sound-absorbing layer 8 is installed on the inner wall of the mounting frame 1 to realize the installation of the sound-absorbing layer 8. When the sound propagates to the rear through the sound-absorbing holes, the sound can be absorbed by the sound-absorbing layer 8.

[0033] Please see Figure 4 The sound-absorbing layer 8 is made of centrifugal glass wool. There is a gap between the back of the sound-absorbing layer 8 and the front of the back panel 2. The sound-absorbing layer 8 is made of centrifugal glass wool, which has a porous structure. When sound waves enter the sound-absorbing layer 8 through the sound barrier panel 6, the centrifugal glass wool can absorb the sound into its internal pores. When the sound waves propagate in the fiber gaps and pores of the centrifugal glass wool, they will rub against the fibers and be continuously reflected in the pores. These processes will gradually convert the sound energy into heat energy, thereby achieving the sound absorption effect. There is a certain gap between the back of the sound-absorbing layer 8 and the back panel 2 to facilitate the passage of airflow.

[0034] Please see Figure 4A waterproof layer 7 is provided on the front side of the sound-absorbing layer 8. The waterproof layer 7 is made of polyvinyl fluoride. The waterproof layer 7 is placed on the front side of the sound-absorbing layer 8 and is made of polyvinyl fluoride. It can effectively block the intrusion of rainwater, dew and other moisture, and keep the sound-absorbing material dry. The main function of the waterproof layer 7 is to prevent moisture from entering the interior of the sound-absorbing layer 8 behind it. In addition, polyvinyl fluoride has a certain degree of resistance and plays an anti-corrosion role. At the same time, polyvinyl fluoride has good anti-ultraviolet properties. It can absorb and reflect most ultraviolet rays, reducing the damage of ultraviolet rays to the sound-absorbing layer 8.

[0035] Please see Figure 1 , Figure 2 and Figure 5 The inner bottom wall of the second mounting bracket 4 is fixedly connected to two fixing blocks 9 and two fixing blocks 10. Fixing blocks 9 are installed on the inner bottom wall of the second mounting bracket 4 to form a fixed connection, and fixing blocks 10 are installed on the inner bottom wall of the second mounting bracket 4 to form a fixed connection. This realizes the installation of fixing blocks 9 and fixing blocks 10. Fixing blocks 9 and fixing blocks 10 can limit the lower half of the photovoltaic panel body 5 to achieve positioning installation.

[0036] Please see Figure 1 , Figure 2 and Figure 5 A top plate 11 is fixedly installed on the upper surface of the mounting bracket 2 4. Two fixing blocks 3 12 are fixedly connected to the inner side wall of the mounting bracket 2 4. The top plate 11 is placed on the upper surface of the mounting bracket 2 4 and fixed by bolts, so that the top plate 11 can be installed and removed. The fixing blocks 3 12 are installed on the inner side wall of the mounting bracket 2 4 and set as a fixed connection to realize the installation of the fixing blocks 3 12.

[0037] Please see Figure 3 and Figure 5 Each fixing block 12 has a fixing bolt 13 fixedly installed on its inner wall, and a fixing block 14 is fixedly installed on the outer surface of each fixing bolt 13. The fixing bolt 13 is installed on the inner wall of the fixing block 12, and the fixing block 14 is installed on the surface of the corresponding fixing bolt 13. Through the fixing block 12, fixing bolt 13 and fixing block 14, the photovoltaic panel body 5 can be clamped, so that the photovoltaic panel body 5 can be fastened.

[0038] Please see Figure 3 and Figure 5A connecting rod 15 is provided above the back panel body 2. The left and right ends of the connecting rod 15 are fixedly connected to the outer surface of the corresponding fixing block 4 14. The connecting rod 15 is set above the back panel body 2, and the left and right ends of the connecting rod 15 are respectively connected to the corresponding fixing block 4 14. After the fixing block 4 14 is installed by the fixing bolt 13, the stability of the photovoltaic panel body 5 after installation can be improved by the connecting rod 15.

[0039] This embodiment presents a photovoltaic sound barrier heat dissipation backplate frame structure. It comprises a backplate body 2, a flow channel 3, a second mounting bracket 4, and a photovoltaic panel body 5. The backplate body 2 is fixed to the inner wall of the first mounting bracket 1, and the flow channel 3 is formed on the back of the backplate body 2. The second mounting bracket 4 is fixed to the upper surface of the first mounting bracket 1, and the photovoltaic panel body 5 is then mounted. Because there are gaps between the backplate body 2 and the first mounting bracket 1, the second mounting bracket 4, and the photovoltaic panel body 5, natural wind can enter the gap between the backplate body 2 and the photovoltaic panel body 5 through the flow channel 3. The airflow forms vortices, enhancing the convective heat transfer effect, thereby removing heat from the back of the photovoltaic panel body 5, reducing temperature rise. The structure is simple, requires no additional energy consumption, and reduces operating and maintenance costs. A waterproof layer 7 protects the sound-absorbing layer 8, preventing water intrusion and reducing UV damage, thus extending the service life of the sound-absorbing layer 8.

[0040] It should be noted that there is a distance between the upper surface of the back panel body 2 and the inner top wall of the mounting frame 2 4, and a distance between the bottom surface of the back panel body 2 and the inner bottom wall of the mounting frame 1. At the same time, there is a distance between the back panel body 2 and the photovoltaic panel body 5 and the sound-absorbing layer 8, so that natural wind is guided through the guide channel 3, enters the gap between the back panel body 2 and the photovoltaic panel body 5, and then exits through the gap below the back panel body 2.

[0041] The working principle of the above embodiments is as follows:

[0042] The back panel body 2 is fixed to the mounting bracket 1 and mounting bracket 2, and a guide groove 3 is opened on the back of the back panel body 2. The photovoltaic panel body 5 is set on the inner wall of the mounting bracket 2. Since there are gaps between the back panel body 2 and the mounting bracket 1, mounting bracket 2, photovoltaic panel body 5 and sound-absorbing layer 8, natural wind can enter the gap between the back panel body 2 and the photovoltaic panel body 5 through the guide groove 3. The airflow forms a vortex, which enhances the convective heat transfer effect, thereby removing the heat on the back of the photovoltaic panel body 5, reducing the temperature rise. The structure is simple, requires no additional energy consumption, and reduces the operation and maintenance costs. By setting a waterproof layer 7 on the front of the sound-absorbing layer 8, the sound-absorbing layer 8 can be protected to prevent rainwater from entering the sound-absorbing layer 8 and reduce the damage of ultraviolet rays to the sound-absorbing layer 8, thus improving the service life of the sound-absorbing layer 8. By setting a fixing block 3 12, fixing bolt 13 and fixing block 4 14, the photovoltaic panel body 5 can be installed. By setting a connecting rod 15, the stability of the photovoltaic panel body 5 after installation can be improved.
