Description

Technical Field

[0001] This invention relates to the field of sound barrier technology, and in particular to a photovoltaic sound barrier device. Background Technology

[0002] Elevated photovoltaic sound barriers typically use photovoltaic modules instead of sound barrier module back panels, integrating the photovoltaic modules and sound barrier modules into a single unit. Due to the influence of the materials and structure of the photovoltaic modules, conventional photovoltaic modules are generally plate-shaped structures. The current installation method of photovoltaic sound barriers means that they can only be installed perpendicular to the ground, and the photovoltaic modules cannot move. This installation method results in low power generation efficiency of the photovoltaic modules, with a power generation efficiency reduction of about 40% compared to horizontal installation or optimal tilt angle installation. Summary of the Invention

[0003] The purpose of this invention is to provide a photovoltaic sound barrier device that effectively improves the noise reduction effect of sound absorption and sound insulation, while also increasing power generation efficiency.

[0004] To achieve the above objectives, the present invention provides a photovoltaic sound barrier device, comprising a sound barrier body and a movable photovoltaic panel. The sound barrier body is assembled from multiple sound barrier units. Each sound barrier unit includes a photovoltaic panel, a sound-absorbing material layer, a sound-insulating back panel, and a frame. The photovoltaic panel includes photovoltaic glass and photovoltaic cells, with the photovoltaic cells sandwiched between two photovoltaic glass panes. An encapsulating material is filled between the photovoltaic cells and the photovoltaic glass panes. Perforations are evenly distributed in the photovoltaic glass panes, except in the area where the photovoltaic cells are located. The sound-absorbing material layer covers one side of the frame, and the photovoltaic panel covers the sound-absorbing material layer, facing a road or railway. The sound-insulating back panel covers the other side of the frame, and the sound-absorbing material layer and the sound-insulating back panel are sandwiched within the frame to form a sound-absorbing cavity. The movable photovoltaic panel includes a photovoltaic module and an adjustment drive mechanism. A flexible sealing material layer is provided on the four sides of the photovoltaic module, which are in close contact with the sound-insulating back panel. Each adjustment drive mechanism includes a first telescopic rod and a second telescopic component. Multiple sets of second telescopic components are arranged in a rectangular pattern and surround the outer periphery of the first telescopic rod. The multiple sets of second telescopic components and the first telescopic rod form a matrix arrangement. Each second telescopic component includes a second telescopic rod and a telescopic connecting rod. The frame is provided with a first mounting slot and multiple second mounting slots. One end of the first telescopic rod is connected to the bottom of the first mounting slot, and the other end of the first telescopic rod is rotatably connected to the photovoltaic module. The second mounting slots are correspondingly arranged with the second telescopic components. One end of the second telescopic rod is connected to the bottom of the second mounting slot, and the other end of the second telescopic rod is rotatably connected to one end of the telescopic connecting rod. The other end of the telescopic connecting rod is rotatably connected to the photovoltaic module. When the adjustment drive mechanism retracts, the first telescopic rod is completely housed in the first mounting slot, the second telescopic component is completely housed in the second mounting slot, the photovoltaic module is tightly attached to the sound insulation back panel, and the movable photovoltaic panels are fully distributed on the sound barrier body in the width direction, with adjacent movable photovoltaic panels closely attached.

[0005] As a preferred embodiment of the present invention, the area of ​​the region in which the via is provided in the photovoltaic glass accounts for 20% to 30% of the total area of ​​the photovoltaic glass.

[0006] As a preferred embodiment of the present invention, the diameter of the via is 2mm to 4mm.

[0007] As a preferred embodiment of the present invention, a sealing strip is provided at the joint between two adjacent sound barrier units.

[0008] As a preferred embodiment of the present invention, the two opposite edges of the sound barrier unit are respectively provided with protrusions and grooves that can fit into each other.

[0009] As a preferred embodiment of the present invention, the two opposite edges of the sound barrier unit have Z-shaped grooves that can fit into each other.

[0010] As a preferred embodiment of the present invention, the photovoltaic module is provided with soundproof glass on both sides, and the thickness of the soundproof glass is 3mm to 4mm.

[0011] As a preferred embodiment of the present invention, the sound insulation back panel is a metal plate.

[0012] As a preferred embodiment of the present invention, the second telescopic component is provided with eight sets and is respectively connected to the four peripheries of the frame, and the first telescopic rod is connected to the center of the frame.

[0013] Compared with the prior art, the photovoltaic sound barrier device of this invention has the following advantages:

[0014] The photovoltaic panel of this invention has through-holes that allow sound to quickly enter the interior of the sound barrier unit, where it is absorbed and consumed by the sound-absorbing material layer, thus attenuating the noise. Combined with the sound-absorbing cavity, this achieves noise reduction. Furthermore, the soundproof back panel enhances the sound insulation effect. When the movable photovoltaic panel is closed, the photovoltaic module can tightly cover the main body of the sound barrier, improving the sound insulation performance of the sound barrier unit panel, reducing the design margin of the main body, achieving better noise reduction with less sound-absorbing material, and lowering the cost of the main body of the sound barrier. Moreover, the photovoltaic panel also functions as a photovoltaic power generation unit, improving space utilization. The first telescopic rod, the second telescopic rod, and the telescopic connecting rod work together to effectively improve the support effect of the adjustment drive mechanism on the photovoltaic module. The angle of the photovoltaic module can be adjusted quickly and easily according to the angle of sunlight, changing the tilt angle and azimuth angle between the photovoltaic module and the sun, increasing the illumination time and area of ​​the photovoltaic module, ensuring the photovoltaic module is always in maximum power generation state, and improving power generation efficiency. This invention effectively improves the noise reduction effect of sound absorption and sound insulation while simultaneously increasing power generation efficiency. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", 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 invention 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 invention.

[0027] like Figures 1 to 7As shown, a preferred embodiment of the photovoltaic sound barrier device of the present invention includes a sound barrier body 1 and a movable photovoltaic panel 2. The sound barrier body 1 is assembled from multiple sound barrier units. Each sound barrier unit includes a photovoltaic panel 11, a sound-absorbing material layer 12, a sound-insulating back panel 13, and a frame 14. The photovoltaic panel 11 includes photovoltaic glass 114 and photovoltaic cells 111. The photovoltaic cells 111 are sandwiched between two photovoltaic glass panels 114. An encapsulation material 113 is filled between the photovoltaic cells 111 and the photovoltaic glass 114. Through-holes 112 are evenly distributed in the photovoltaic glass 114 except for the area where the photovoltaic cells 111 are located. Sound waves enter the sound barrier through the through-holes 112. The sound-absorbing material layer 12 inside the unit reduces noise through sound absorption. The sound-absorbing material layer 12 is covered on one side of the frame 14. The photovoltaic panel 11 is covered on the sound-absorbing material layer 12, and the photovoltaic panel 11 faces the road or railway. The sound-insulating back panel 13 is covered on the other side of the frame 14. The sound-absorbing material layer 12 and the sound-insulating back panel 13 are sandwiched in the frame 14 to form a sound-absorbing cavity 141. The movable photovoltaic panel 2 includes a photovoltaic module 21 and an adjustment drive mechanism. The photovoltaic module 21 is provided with a flexible sealing material layer 26 on its four sides that are in close contact with the sound-insulating back panel 13. When the photovoltaic module 21 is in close contact with the sound-insulating back panel 13, it can reduce the noise barrier. The vibration of the unit panel sound insulation back panel 13 improves the noise reduction effect of the overall structure of the sound photovoltaic sound barrier device, making it easier to meet the nighttime noise emission standards; each set of the adjustment drive mechanism includes a first telescopic rod 22 and a second telescopic component 23. Multiple sets of second telescopic components 23 are arranged in a rectangle and surround the outer periphery of the first telescopic rod 22. Multiple sets of second telescopic components 23 and the first telescopic rod 22 form a matrix arrangement. Each second telescopic component 23 includes a second telescopic rod 24 and a telescopic connecting rod 25. The frame 14 is provided with a first mounting groove 142 and multiple second mounting grooves 143. One end of the first telescopic rod 22 is connected to the bottom of the first mounting groove 142. The other end of 2 is rotatably connected to the photovoltaic module 21. The second mounting groove 143 and the second telescopic component 23 are respectively arranged one-to-one. One end of the second telescopic rod 24 is connected to the bottom of the second mounting groove 143. The other end of the second telescopic rod 24 is rotatably connected to one end of the telescopic connecting rod 25. The other end of the telescopic connecting rod 25 is rotatably connected to the photovoltaic module 21. As the position of the sun changes continuously, by adjusting the extension length of the first telescopic rod 22 and each of the second telescopic rods 24 and the telescopic connecting rod 25, the angle of the photovoltaic module 21 can be arbitrarily adjusted so that the photovoltaic module 21 in the photovoltaic sound barrier device can always face the sun and maximize the power generation of the photovoltaic module 21.When the adjustment drive mechanism retracts, the first telescopic rod 22 is fully housed within the first mounting groove 142, the second telescopic component 23 is fully housed within the second mounting groove 143, the photovoltaic module 21 is tightly attached to the sound insulation back panel 13, and two adjacent movable photovoltaic panels 2 are tightly fitted together. Furthermore, the movable photovoltaic panels 2 are offset from the sound barrier units, covering the joint between two adjacent sound barrier units. This effectively seals the joint between the two sound barrier units, reducing the design margin of the sound barrier body 1, achieving optimal sound absorption and noise reduction with less sound-absorbing material, and lowering the cost of the sound barrier body 1. Thus, a portion of the second telescopic component 23 in the movable photovoltaic panel 2 is connected to the frame 14 of one sound barrier unit, while the remaining portion of the second telescopic component 23 in the movable photovoltaic panel 2 is connected to the frame 14 of another adjacent sound barrier unit. The photovoltaic sound barrier device can be a semi-enclosed or fully enclosed photovoltaic sound barrier device. The vertical sections of the semi-enclosed or fully enclosed photovoltaic sound barrier device are installed vertically, while the top of the fully enclosed photovoltaic sound barrier device is installed horizontally.

[0028] In addition, the photovoltaic sound barrier device is also equipped with a wind speed sensor. When the detected wind speed is greater than the preset value, the adjustment drive mechanism retracts the photovoltaic module 21, effectively protecting the photovoltaic module 21 and the adjustment drive mechanism, improving the safety and structural stability of use. When the wind speed is too high, if the adjustment drive mechanism extends the photovoltaic module 21, it is easy to cause the first telescopic rod 22, the second telescopic component 23 and the telescopic connecting rod 25 to deform, resulting in the photovoltaic module 21 not being able to stick tightly to the sound barrier body 1, affecting the sound insulation effect. By retracting the photovoltaic module 21 in time, the service life of the movable photovoltaic panel 2 can be effectively extended.

[0029] The photovoltaic panel 11 of this invention has through holes 112 that allow sound to quickly enter the interior of the sound barrier unit, where it is absorbed and consumed by the sound-absorbing material layer 12, thus attenuating the noise. Combined with the sound absorption effect of the sound-absorbing cavity 141, this achieves noise reduction. Furthermore, the sound-insulating back panel 13 enhances the sound insulation effect. Simultaneously, when the movable photovoltaic panel 2 is closed, the photovoltaic module 21 can tightly cover the sound barrier body 1, improving the sound insulation performance of the sound barrier unit panel, reducing the design margin of the sound barrier body 1, achieving better noise reduction with less sound-absorbing material, and lowering the cost of the sound barrier body 1. Furthermore, the photovoltaic panel 11 can also function as a photovoltaic power generation unit, improving space utilization. The first telescopic rod 22, the second telescopic rod 24, and the telescopic connecting rod 25 work together to effectively improve the support effect of the adjustment drive mechanism on the photovoltaic module 21. According to the angle of solar irradiation, the angle of the photovoltaic module 21 can be adjusted quickly and easily, changing the tilt angle and azimuth angle between the photovoltaic module 21 and the sun, increasing the illumination time and area of ​​the photovoltaic module 21, so that the photovoltaic module 21 is always in the maximum power generation state, improving power generation efficiency. This invention can effectively improve the noise reduction effect of sound absorption and sound insulation, while improving power generation efficiency.

[0030] For example, the area of ​​the photovoltaic glass 114 with the through hole 112 accounts for 20% to 30% of the total area of ​​the photovoltaic glass 114, that is, the area of ​​the photovoltaic glass 114 with the photovoltaic cell 111 accounts for 70% to 80% of the total area of ​​the photovoltaic glass 114. The aperture of the through hole 112 is 2mm to 4mm. This ensures that the sound absorption and noise reduction effect of the sound barrier body 1 is not affected, and at the same time, it can also ensure the strength of the photovoltaic glass 114 with the through hole 112, thereby ensuring the overall structural strength of the photovoltaic panel 11.

[0031] For example, a sealing strip 144144 is provided at the splice between two adjacent sound barrier units, which can reduce the sound leakage defect at the splice between adjacent sound barrier units.

[0032] In this embodiment, as Figure 6 As shown, the two opposite edges of the sound barrier unit are respectively provided with interlocking protrusions 15 and grooves 16. The protrusions 15 and grooves 16 cooperate to form a bent structure, reducing noise leakage from the joints between adjacent sound barrier units and improving the noise reduction effect of the entire photovoltaic sound barrier device. In another embodiment, as... Figure 7 As shown, the two opposite edges of the sound barrier unit have Z-shaped grooves 17 that can fit into each other.

[0033] For example, the photovoltaic module 21 is provided with soundproof glass on both sides, and the thickness of the soundproof glass is 3mm to 4mm. When the movable photovoltaic panel 2 is in the closed state, the sound insulation of the sound barrier body is improved.

[0034] In this embodiment, the sound insulation back panel 13 is a metal plate. Noise enters the sound barrier unit through the through hole 112 on the photovoltaic panel 11. The noise energy is attenuated to a certain extent by the absorption and consumption of the sound-absorbing material layer 12 and the sound-absorbing cavity 141. Then, the noise is controlled by the sound insulation performance of the sound insulation back panel 13, and finally the noise sound pressure level passing through the sound barrier unit is reduced to achieve the purpose of noise reduction.

[0035] like Figure 8 As shown, in this embodiment, the second telescopic component 23 is provided in eight groups and is respectively connected to the four peripheries of the photovoltaic module 21. The second telescopic component 23 includes the second telescopic component I 231, the second telescopic component II 232, the second telescopic component III 233, the second telescopic component IV 234, the second telescopic component V 235, the second telescopic component VI 236, the second telescopic component VII 237 and the second telescopic component VIII 238, that is, the second mounting slot 143 is provided with eight corresponding slots, and the first telescopic rod 22 is connected to the center of the photovoltaic module 21.

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 invention based on the specific circumstances.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
