Description

Technical Field

[0001] This utility model relates to the field of road sound barrier technology, and in particular to an integrated structure of photovoltaic sound barrier. Background Technology

[0002] With the acceleration of urbanization, population density and car ownership are constantly increasing. The distance between residences and roads, especially near elevated highways, is shrinking, and noise from vehicles is severely impacting residents' lives. Therefore, sound barriers with sound-absorbing properties are often installed along highways to reduce the impact of road noise on nearby residents.

[0003] Sound barriers typically only provide noise reduction and insulation, offering a relatively limited function. However, with advancements in photovoltaic (PV) power generation technology, their economic viability and practicality have improved, leading to the idea of ​​combining PV power generation with sound barriers. PV sound barriers not only reduce noise but also generate electricity using solar energy, achieving energy conservation and environmental protection. However, the fully enclosed structure of PV sound barriers is composed of multiple components, such as the joints between PV panels and between the panels and the frame. Improper sealing at these joints can allow rainwater to seep in, affecting power generation efficiency and lifespan. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an integrated photovoltaic sound barrier structure that combines photovoltaic power generation and sound insulation, while also preventing the photovoltaic modules from being affected by rainwater and extending their service life.

A plurality of screen components are covered on the side of the frame facing away from the ground. Each screen component includes a photovoltaic sound barrier, side screens, and corner screens. The photovoltaic sound barrier includes a single frame and photovoltaic modules, with the photovoltaic modules housed within the single frame. Multiple photovoltaic sound barriers are spliced ​​together to cover the top of the frame. A second drainage channel is provided within the single frame to collect and drain rainwater, preventing rainwater from seeping into the photovoltaic modules. Side screens are located on the outer sidewall of the frame. Corner screens are located at the top corner of the frame, with one end connected to the photovoltaic sound barrier and the other end connected to the side screen.

[0006] According to an embodiment of this utility model, an integrated photovoltaic sound barrier structure has at least the following technical effects: Multiple screen components completely cover the frame, forming a fully enclosed sound barrier. The photovoltaic sound barrier directly serves as the top sound-absorbing screen of the fully enclosed sound barrier, integrating photovoltaic power generation and sound insulation. This reduces urban noise pollution on the one hand, and alleviates the pressure on urban photovoltaic construction land on the other. The photovoltaic sound barrier includes a single frame and photovoltaic modules. The single frame serves to connect, fix, and protect the photovoltaic modules. A second drainage channel is provided inside the single frame. When water droplets seep in from the single frame, the water droplets will flow into the second drainage channel instead of continuing to seep into the photovoltaic modules, preventing the photovoltaic modules from being affected by rainwater and improving their service life.

[0007] According to some embodiments of the present invention, a photovoltaic module includes a cover plate and a photovoltaic panel. The cover plate is disposed on the side of the photovoltaic panel away from the frame and is used to protect the photovoltaic panel.

[0008] According to some embodiments of the present invention, the single frame has a mounting cavity that matches the size of the photovoltaic panel and can be used to install the photovoltaic panel; the upper part of the mounting cavity is recessed inward toward the single frame to form a first groove, which can be used to insert the edge of the cover plate.

[0009] According to some embodiments of the present invention, the single frame includes a main frame and a frame cover. The frame cover is detachably disposed on the top of the main frame. A first groove is formed at the top of the main frame where it connects with the frame cover. The main frame and the frame cover cooperate to limit the upper and lower positions of the cover plate.

[0010] According to some embodiments of the present invention, the second guide channel is opened on one side of the bottom of the first groove and communicates with the first groove to receive water entering the first groove; the second guide channel extends along the length direction of the single frame, penetrates the single frame and forms a drainage hole on its surface.

[0011] According to some embodiments of this utility model, several photovoltaic sound shields are spliced ​​together along the length of the second guide channel, and the second guide channel is aligned and connected to form a drainage channel.

[0012] According to some embodiments of the present invention, a water-absorbing strip is attached to the opening of the second guide channel to prevent water in the second guide channel from flowing back.

[0013] According to some embodiments of the present invention, the photovoltaic module further includes a sound-absorbing structure, which includes sound-absorbing cotton and a sound-absorbing metal plate. The sound-absorbing metal plate is disposed at the bottom of the frame of the unit, and the sound-absorbing cotton is placed between the sound-absorbing metal plate and the photovoltaic panel.

[0014] According to some embodiments of this utility model, a second groove is provided at the bottom of the single frame, and the second groove matches the sound-absorbing metal plate so that the edge part of the sound-absorbing metal plate can be inserted.

[0015] According to some embodiments of this utility model, the single frame is provided with a connecting hole, which passes through the frame cover, the first groove, the main frame and communicates with the second groove in sequence.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Reference Figures 1 to 4 An integrated photovoltaic sound barrier structure according to an embodiment of the present invention includes an arched frame 100, a photovoltaic sound barrier body 200, a side screen body 300, and a corner screen body 400.

[0031] An arched frame 100 is supported on the ground and spans across both sides of the road. The side of the frame 100 facing away from the ground is covered with several screen components, including a photovoltaic sound screen 200, a side screen 300, and a corner screen 400.

[0032] Multiple photovoltaic sound screens 200 are spliced ​​together and cover the top of the frame 100. Side screens 300 are set on the outer side of the side wall of the frame 100. Corner screens 400 are set at the top corner of the frame 100, with one end connected to the photovoltaic sound screen 200 and the other end connected to the side screen 300.

[0033] The frame 100 is fully covered by multiple screen components to form a fully enclosed sound barrier. The gaps between the photovoltaic sound barrier 200, the side screens 300, and the corner screens 400 are filled with waterproof sealing strips to ensure that noise does not leak out. The waterproof sealing strips can be neoprene rubber strips or EPDM rubber strips. The photovoltaic sound barrier 200 is directly used as the top sound-absorbing screen of the fully enclosed sound barrier, integrating photovoltaic power generation and sound insulation and noise reduction. On the one hand, it reduces urban noise pollution, and on the other hand, it alleviates the pressure on urban photovoltaic construction land.

[0034] Reference Figure 2 The photovoltaic sound shield 200 includes a single frame 210 and a photovoltaic module 220. The photovoltaic module 220 is located inside the single frame 210. The single frame 210 can connect, fix and protect the photovoltaic module 220. Multiple first guide grooves 211 are provided on the single frame 210 to guide rainwater out and prevent the photovoltaic module 220 from being in contact with water for a long time.

[0035] However, in extremely humid conditions, water droplets may flow from the individual frame 210 into the photovoltaic module 220. Therefore, in this embodiment, a second guide channel 212 is provided inside the individual frame 210. When water droplets seep in from the individual frame 210, the water droplets will flow into the second guide channel 212 and will not continue to seep into the photovoltaic module 220.

[0036] Reference Figure 3 In some embodiments of this utility model, the photovoltaic module 220 includes a cover plate 221 and a photovoltaic panel 222. The cover plate 221 is located on the side of the photovoltaic panel 222 away from the frame 100. The cover plate 221 can be a transparent glass plate, which can prevent the photovoltaic panel 222 from being directly exposed to the external environment, avoid the erosion and damage of wind and rain to the photovoltaic panel 222, and play a good protective role for the photovoltaic panel 222.

[0037] Reference Figures 3 to 4 In a further embodiment of this utility model, the single frame 210 has a mounting cavity 214, which matches the size of the photovoltaic panel 222 and can be used to install the photovoltaic panel 222. In order to fully protect the photovoltaic panel 222, the cover plate 221 is larger than the photovoltaic panel 222 to fully cover the photovoltaic panel 222. Correspondingly, the cross-sectional area of ​​the mounting space of the cover plate 221 is also larger than the cross-sectional area of ​​the mounting cavity 214. In this embodiment, a first groove 217 is formed recessed above the mounting cavity 214 facing the single frame 210, and the edge of the cover plate 221 can be inserted into the first groove 217.

[0038] Reference Figures 3 to 4In a further embodiment of this utility model, the single frame 210 includes a main frame 215 and a frame cover 216. The frame cover 216 is detachably mounted on the top of the main frame 215. A first groove 217 is formed at the top of the main frame 215 where it meets the frame cover 216. After the cover plate 221 is installed, the main frame 215 and the frame cover 216 cooperate and are fixedly connected by screws, which can limit the upper and lower position of the cover plate 221.

[0039] Reference Figure 4 In a further embodiment of this utility model, a second guide channel 212 is formed on one side of the bottom of the first groove 217 and communicates with the first groove 217 to receive water entering the first groove 217; the second guide channel 212 extends along the length of the single frame 210, penetrates the single frame 210, and forms a drain hole 213 on its surface. When water droplets falling on the single frame 210 and the cover plate 221 flow into the first groove 217, the water droplets will further flow into the second guide channel 212 under the action of gravity, and after gathering in the second guide channel 212, they will be discharged from the drain hole 213.

[0040] In a further embodiment of this utility model, several photovoltaic sound barrier bodies 200 are spliced ​​along the length direction of the second guide channel 212 to form a photovoltaic sound barrier group. Multiple photovoltaic sound barrier groups are spliced ​​along a direction perpendicular to the second guide channel 212, and finally the top of the frame 100 is covered. The second guide channel 212 is aligned and connected to form a drainage channel. After the rainwater is collected, it is discharged from the drainage hole 213 on the outermost photovoltaic sound barrier body 200.

[0041] Reference Figure 3 In a further embodiment of the present invention, a water-absorbing strip 227 is attached to the opening of the second guide channel 212 to prevent water in the second guide channel 212 from flowing back.

[0042] Specifically, the water-absorbing strip 227 is attached to the bottom of the first groove 217 and the opening of the second guide channel 212. The water-absorbing strip 227 can be made of sponge material. When water droplets falling on the unit frame 210 and the cover plate 221 flow into the first groove 217, the water-absorbing strip 227 absorbs the water droplets. Even if the water droplets are not absorbed and directly enter the second guide channel 212, the water in the second guide channel 212 will not flow out of the first groove 217. The setting of the water-absorbing strip 227 can not only prevent water backflow, but also absorb the small amount of water in the second guide channel 212 in time, keeping the connection between the unit frame 210 and the cover plate 221 dry, which is more conducive to protecting the photovoltaic panel 222.

[0043] Furthermore, referring to Figure 3The edge of the cover plate 221 inserted into the first groove 217 is slightly shorter than the first groove 217. When the cover plate 221 is inserted into the first groove 217, the edge of the cover plate 221 abuts against the water-absorbing strip 227, pressing the water-absorbing strip 227 while also allowing the water-absorbing strip 227 to maintain a certain space for expansion and deformation, so that the water-absorbing strip 227 can absorb water in time.

[0044] Reference Figure 3 In some embodiments of this utility model, the photovoltaic module 220 further includes a sound-absorbing structure 223, which includes a sound-absorbing cotton 224 and a sound-absorbing metal plate 225. The sound-absorbing metal plate 225 is disposed at the bottom of the single frame 210, and the sound-absorbing cotton 224 is placed between the sound-absorbing metal plate 225 and the photovoltaic panel 222.

[0045] With this configuration, some noise is reflected by the sound-absorbing metal plate 225, while the rest passes through the metal plate 225 and is absorbed by the sound-absorbing cotton 224, resulting in better sound insulation and noise reduction compared to traditional sound barriers. The sound-absorbing cotton 224 can be centrifugal cotton, rock wool, or slag wool.

[0046] Furthermore, the sound-absorbing metal plate 225 is evenly covered with micropores so that noise can pass through the sound-absorbing metal plate 225 and be absorbed by the sound-absorbing cotton 224.

[0047] Reference Figure 3 In a further embodiment of the present invention, a second groove 218 is provided at the bottom of the single frame 210, and the second groove 218 matches the sound-absorbing metal plate 225 so that the edge portion of the sound-absorbing metal plate 225 can be inserted.

[0048] In a further embodiment of this utility model, the single frame 210 is provided with a connecting hole 219, which passes through the frame cover 216, the first groove 217, and the main frame 215 in sequence and communicates with the second groove 218. The cover plate 221 and the sound-absorbing metal plate 225 are provided with mounting holes 226 that match the connecting hole 219. The connecting hole 219 and the mounting hole 226 are aligned to allow for the insertion of a connector. The connector can be a bolt. The single frame 210 and the photovoltaic module 220 are connected and fixed by the connector.

[0049] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
