[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] Example 1:

[0035] like Figures 1 to 5 As shown, in the technical solution of Example 1 of the present application, a photovoltaic sound insulation mechanism is provided, which mainly includes: a mounting frame 10, a first sound insulation component 20 and a plurality of photovoltaic components 30, the mounting frame 10 includes a base 11 and a plurality of vertical poles 12, the vertical poles 12 are fixed on the base 11, and a mounting position 13 is formed between adjacent vertical poles 12; the first sound insulation component 20 includes a first sound insulation structure 21, and the two ends of the first sound insulation structure 21 are respectively connected to the adjacent vertical poles 12; the photovoltaic component 30 includes at least one second sound insulation structure 31 and two light receiving structures 32, the second sound insulation structure 31 is arranged between the two light receiving structures 32, and the light receiving surface 321 of the light receiving structure 32 is arranged away from the second sound insulation structure 31, and the first sound insulation structure 21 and one or more photovoltaic components 30 are arranged in the mounting position 13.

[0036] The main sound insulation effect is achieved by the arrangement of the first sound insulation component 20, and one or more photovoltaic components 30 having at least two light receiving structures 32 are arranged between the first sound insulation structure 21 of the first sound insulation component 20, and their light receiving surfaces 321 are respectively facing different directions, which can adapt to sunlight at different illumination angles, make full use of the illumination of light, avoid waste of light, and increase power generation. This application effectively solves the problem that the actual light receiving time of the current sound insulation wall integrated with photovoltaic panels is short during application, which affects the power generation efficiency.

[0037] At the same time, the second sound insulation structure 31 between the two light receiving structures 32 also increases the sound insulation effect at the installation position of the photovoltaic component 30, thereby avoiding the reduction of the sound insulation effect caused by the sound waves generated by the photovoltaic component 30 passing through.

[0038] It should be noted that in the technical solution of embodiment 1, the vertical pole 12 can specifically be an I-beam, and the two side grooves of the I-beam are used to clamp the first sound insulation component 20. The vertical pole 12 is also provided with a plurality of through holes 14 that can be used for assembly, fixation or wiring.

[0039] like Figure 2 As shown, in the technical solution of Example 1, a snap-in groove 211 is formed on the side of the first sound insulation structure 21 facing the photovoltaic module 30, and the photovoltaic module 30 is snap-fitted into the snap-in groove 211. The provision of the snap-in groove 211 can form a circumferential limit for the photovoltaic module 30, so that the circumference of the photovoltaic module 30 is completely fixed, making installation more convenient and reliable.

[0040] Both side end surfaces of the first sound insulation structure 21 are engaged with the vertical pole 12 , and the end surfaces adjacent to the both side end surfaces form engaging grooves 211 , so that at least the side facing the photovoltaic component 30 can form a fit with the photovoltaic component 30 .

[0041] It can be understood that multiple first sound insulation structures 21 can be assembled between adjacent vertical poles 12 to achieve first sound insulation components 20 of different heights. On the first sound insulation structure 21 that is not in contact with the photovoltaic component 30, one end is set as a snap-in groove 211 and the other end is set as a snap-in protrusion that fits the snap-in groove 211. The two are snap-fitted together to achieve the combination of the first sound insulation structure 21. Such a setting realizes snap-fit ​​fixation without the need to use other fixing materials to fix the adjacent first sound insulation structures 21. At the same time, the snap-fitting at multiple positions makes the integrity better, and the overall structural strength can meet the requirements of the sound insulation effect.

[0042] like Figure 2 As shown, in the technical solution of Example 1, the first sound insulation structure 21 includes a flexible abutment member 212 disposed within the engaging groove 211, and the wire assembly 33 of the photovoltaic module 30 abuts against the flexible abutment member 212. The provision of the flexible abutment member 212 provides a certain buffering effect, which can adapt to the placement of the wire assembly 33 without causing damage, and also provides protection for the wire assembly 33.

[0043] The flexible abutment member 212 is made of a cushioning material, specifically a foam material, which is easy to manufacture and has high plasticity, making it easy to form into a desired shape. Specifically, it can be formed into a shape that wraps around the wire assembly 33. This prevents moisture or raindrops from invading the wire assembly 33 even in rainy weather, thereby preventing the wire assembly from being damaged and thus improving its service life.

[0044] like Figure 2 As shown, in the technical solution of Example 1, the first sound insulation structure 21 comprises a first sound-absorbing material layer 213 and two partitions 214. The first sound-absorbing material layer 213 is positioned between the two partitions 214, and the engaging groove 211 is formed between the two partitions 214. This three-layered first sound insulation structure 21 effectively blocks noise transmission and provides excellent sound insulation. The engaging groove 211 is formed directly into the two partitions 214, eliminating the need for additional components. This highly integrated structure facilitates transportation and installation, making it more convenient to operate.

[0045] In some optional embodiments, the partition 214 can be made of sound insulation material, and can be made of heavy and dense materials such as steel plates, lead plates, brick walls, etc., which are required to be dense without pores or gaps and have a large weight.

[0046] The first sound-absorbing material layer 213 is made of a sound-absorbing material, which is a loose and porous material such as slag wool, blanket, sound-insulating foam, foam, etc. The sound waves penetrate into the pores of the material, and the pores are mostly open holes that penetrate each other. The sound waves are subjected to friction and viscous resistance of air molecules, and the fine fibers are mechanically vibrated, thereby converting the sound energy into heat energy.

[0047] The use of the partition 214 reflects most of the noise and reduces the amount of transmission, while the first sound-absorbing material layer 213 converts a small amount of noise into heat energy to hinder the propagation of noise. The combination of the two has a good sound insulation effect.

[0048] like Figure 2 As shown, in the technical solution of Example 1, the second sound insulation structure 31 includes a second sound absorbing material layer 311, and the first sound absorbing material layer 213 is connected to the second sound absorbing material layer 311. The second sound absorbing material layer 311 is provided to absorb noise passing through the light receiving structure 32, thereby reducing noise propagation at the location of the photovoltaic module 30.

[0049] The first sound absorbing material layer 213 and the second sound absorbing material layer 311 are connected to each other to achieve noise blocking consistency, and can be combined together by extrusion contact or integral molding.

[0050] The first sound absorbing material layer 213 and the second sound absorbing material layer 311 are optionally integrated into one body by an integral molding method, and specifically can be a silicone pad with dense holes or sound-absorbing cotton, etc., which can also play a buffering role.

[0051] The thickness of the second sound-absorbing material layer 311 is greater than or equal to the first sound-absorbing material layer 213. This setting is based on the fact that the sound insulation effect of the light-receiving structure 32 is lower than the sound insulation effect of the partition 214. The thickness of the second sound-absorbing material layer 311 can be increased to increase the sound absorption effect, while providing a more effective buffering effect for the light-receiving structure 32.

[0052] It is understood that in the technical solution of Example 1, the number and position of photovoltaic modules 30 are not limited and can be increased or decreased according to the actual light-receiving surface 321. The back side of a light-receiving surface 321 of a photovoltaic module 30 can be either a partition 214 or another light-receiving structure 32, which can be selected according to actual use. The number of second sound insulation structures 31 can also be increased or decreased according to the actual scenario, as well as the combination of sound-absorbing and sound-insulating materials, which can achieve better adaptability.

[0053] Example 2:

[0054] like Figure 6 As shown, the technical solution of Example 2 differs from Example 1 in that the first sound insulation structure 21 in Example 2 includes two opposing partitions 214, and the second sound insulation structure 31 includes two opposing first safety glass panels 312. A negative pressure space is formed between the two partitions 214 and the two first safety glass panels 312. This arrangement eliminates the medium conditions for noise transmission between the two partitions 214 and the two first safety glass panels 312, thereby effectively blocking noise transmission and achieving excellent sound insulation.

[0055] It can be understood that the channel formed by the two partitions 214 is connected to the channel formed between the two first safety glasses 312, so that the formation of a negative pressure space can be achieved with only one negative pressure generating source. The negative pressure generating source can directly use the electric energy generated by the photovoltaic assembly 30 to achieve the purpose of automatic operation.

[0056] The first safety glass 312 is a type that will not break even after severe vibration or impact, and even if it breaks, it is unlikely to produce fragments. It can effectively protect the photovoltaic layer 322 it is connected to, while meeting the installation requirements of the light-receiving structure 32 and providing a certain quality to increase the overall structural stability of the photovoltaic module.

[0057] In some optional embodiments, the partition 214 is made of the same material as the first safety glass 312, and the two are an integrally formed structure. Such a configuration is more compact, easier to assemble, and has a higher degree of structural integration.

[0058] like Figure 6 As shown, in the technical solution of Example 2, the spacing distance between the two partitions 214 is equal to the spacing distance between the two first safety glasses 312. In such a setting, there will be no change in fluid pressure between the channel formed by the two partitions 214 and the channel formed between the two first safety glasses 312. It can be understood that the process of generating negative pressure is not a complete vacuum state, and the negative pressure equipment is required to continuously absorb the air in the channel. During the absorption process, the flow of air will generate fluid pressure on the two partitions 214 and the two first safety glasses 312 located on both sides of the channel. If the channel formed by the two changes, the fluid pressure will change, which can easily cause the joint position of the two to move or be damaged, resulting in failure of the negative pressure, thereby affecting the sound insulation effect.

[0059] like Figure 6As shown, in the technical solution of Example 2, at least one light-receiving structure 32 includes a photovoltaic layer 322 and a second safety glass 323. The photovoltaic layer 322 is located between the first safety glass 312 and the second safety glass 323, forming a negative pressure space between the first safety glass 312 and the second safety glass 323. This arrangement firstly allows the first safety glass 312 and the second safety glass 323 to be more tightly bonded to the photovoltaic layer 322, while the negative pressure space between the first safety glass 312 and the second safety glass 323 provides good sound insulation, thereby enhancing the sound insulation effect of the photovoltaic sound insulation mechanism.

[0060] like Figure 6 As shown, in the technical solution of Example 2, the negative pressure space formed between the two partitions 214 and the two first safety glasses 312 is connected to the negative pressure space formed between the first safety glasses 312 and the second safety glasses 323. This arrangement ensures that the channels formed by the two partitions 214, the channel formed between the two first safety glasses 312, and the two channels formed by the first safety glasses 312 and the second safety glasses 323 in the two photovoltaic modules 30 are all interconnected. This allows the formation of a negative pressure space to be achieved using only a single negative pressure generating source.

[0061] It can be understood that the above-mentioned setting causes the second safety glass 323 in the two outermost photovoltaic components 30 to be respectively subjected to the action of atmospheric pressure and squeezed inward at the same time. At this time, the overall structural stability is better, the first safety glass 312 does not generate force, and the internal structure is more stable and reliable.

[0062] In order to facilitate the stabilization of the negative pressure space formed between the two partitions 214 and the two first safety glasses 312, and the negative pressure space formed between the first safety glass 312 and the second safety glass 323, partitions can be set between the two partitions 214 and the two first safety glasses 312. The partitions serve to separate the space to avoid the two partitions 214 and the two first safety glasses 312 being directly squeezed together under negative pressure, resulting in no negative pressure space, and then the noise is transmitted through the contacting partitions 214 and the first safety glasses 312.

[0063] Both the above-mentioned embodiment 1 and embodiment 2 can flexibly use photovoltaic sound insulation mechanisms to solve the noise pollution problem in life according to different regions, different locations, and different noise reduction levels. They not only improve the effective conversion of solar energy, increase economic benefits and energy utilization, but also can meet the requirements of multiple scenarios in terms of sound insulation effects, thereby broadening the application field of photovoltaic technology.

[0064] Secondly, some exemplary embodiments of the present application further provide a photovoltaic soundproof wall, comprising a power supply circuit and multiple photovoltaic soundproofing mechanisms such as those described in any of the above embodiments. The mounting frames 10 of the photovoltaic soundproofing mechanisms are sequentially connected, and each photovoltaic module 30 is electrically connected to the power supply circuit. The beneficial effects of the photovoltaic soundproofing mechanisms are described in the above embodiments and will not be further elaborated here.

[0065] The power connection circuit includes a junction box, inverter, transformer and other equipment that are suitable for the DC conversion of the photovoltaic sound insulation mechanism. When the DC power generated by the photovoltaic sound insulation mechanism passes through a certain electrical connection method and passes through the junction box, inverter, transformer and other equipment, it can be directly used. For example, electrical appliances such as street lights can also be directly connected to the power grid to complete the recycling of current.

[0066] It is understood that the mounting brackets 10 of the photovoltaic sound insulation mechanism can be connected sequentially, and the connection angles can be adapted to different roads or scenes, and can be flexibly used according to different areas, different locations, and different noise reduction levels. It meets relevant standards such as highway environmental protection and civil building sound insulation design specifications.

[0067] So far, the various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.

Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application.
