Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and more specifically, to a BIPV photovoltaic module with sound insulation function. Background Technology

[0002] BIPV (Building Integrated Photovoltaics) refers to the installation of photovoltaic (PV) modules on the surface of a building envelope to provide electricity while simultaneously serving as a functional part of the building structure, replacing some traditional building components such as roofs, facades, and awnings. PV modules, also known as solar cell modules, are a type of green energy device. In some applications, such as rooftop BIPV, opaque curtain walls, railings, or awning BIPV, the back of the module itself does not need to transmit light. However, existing technologies have the following shortcomings in their application:

[0003] Traditional BIPV photovoltaic modules have significant shortcomings in sound insulation. Ordinary photovoltaic modules generally lack corresponding sound insulation structures, which makes it easy for external sounds to pass through the modules and cannot effectively block external noise, affecting the quiet environment inside the building.

[0004] Therefore, there is an urgent need for a BIPV photovoltaic module with sound insulation function to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a BIPV photovoltaic module with sound insulation function, which can solve the problem that traditional BIPV photovoltaic modules have significant deficiencies in sound insulation. Ordinary photovoltaic modules generally lack corresponding sound insulation structures, causing external sounds to easily pass through the module and failing to effectively block external noise.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The application is as follows:

[0008] A BIPV photovoltaic module with sound insulation function includes a frame body, which includes an outer frame and an inner frame located on the inner surface of the outer frame. The outer frame has two symmetrically distributed slots on its front side, and a photovoltaic panel is installed in both slots. Two symmetrically arranged sealing gaskets are provided between the photovoltaic panel and the outer frame. A sound insulation board is provided on the inner surface of the inner frame. The sound insulation board has several evenly arranged well-shaped grooves, several notches, and several polygonal grooves on its front side. Several hemispherical protrusions are provided on the inner surface of the notches. Several arc-shaped grooves are provided on the front side of the sound insulation board.

[0009] As a preferred technical solution of this application, a plurality of well-shaped grooves and a plurality of polygonal grooves are arranged alternately, and the plurality of well-shaped grooves are respectively located outside a plurality of recesses.

[0010] As a preferred technical solution of this application, the arc-shaped groove is arranged horizontally, and a plurality of the arc-shaped grooves are arranged vertically at equal intervals, and the length of the arc-shaped groove is greater than half the width of the sound insulation board.

[0011] As a preferred technical solution of this application, the photovoltaic panel and the outer frame are connected by two symmetrically arranged fastening bolts.

[0012] As a preferred technical solution of this application, the sealing gasket is U-shaped and is installed on the inner surface of the outer frame by adhesive. The outer surface of the photovoltaic panel is in contact with the two sealing gaskets.

[0013] As a preferred technical solution of this application, the frame body is integrally formed, and the back of the photovoltaic panel is attached to the inner frame and the sound insulation board.

[0014] As a preferred technical solution of this application, the outer surface of the sound insulation board is attached to the inner surface of the inner frame, and the sound insulation board is installed on the back of the photovoltaic panel by adhesive.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, the several well-shaped grooves, notches, polygonal grooves, and arc-shaped grooves opened on the front of the sound insulation panel can reflect, refract, and absorb sound, effectively enhancing the sound insulation effect of the sound insulation panel. This gives the entire photovoltaic module excellent sound insulation performance, effectively blocking external noise. This is beneficial for practical use.

[0017] 2. The integrated design of the frame body and the setting of the sealing gasket ensure the sealing performance of the photovoltaic module, which not only helps to improve the sound insulation effect, but also prevents external dust, moisture and other substances from entering the module, effectively protecting the photovoltaic panel and sound insulation board and other components, which is conducive to its long-term stable use.

[0027] Example:

[0028] like Figure 1-5As shown, this embodiment proposes a BIPV photovoltaic module with sound insulation function, including a frame body 1. The frame body 1 includes an outer frame 2 and an inner frame 3 located on the inner surface of the outer frame 2. The front of the outer frame 2 has two symmetrically distributed slots 4, in which a photovoltaic panel 5 is installed. Two symmetrically arranged sealing gaskets 6 are provided between the photovoltaic panel 5 and the outer frame 2. A sound insulation board 7 is provided on the inner surface of the inner frame 3. The outer surface of the sound insulation board 7 is attached to the inner surface of the inner frame 3. The sound insulation board 7 is installed on the back of the photovoltaic panel 5 by adhesive. When working, when sound travels to the photovoltaic module, it first contacts the photovoltaic panel 5. Some sound passes through the photovoltaic panel 5 and reaches the sound insulation board 7. The front of the sound insulation board 7 has a number of evenly arranged well-shaped grooves 8, a number of notches 9, and a number of... The polygonal groove 10, along with several well-shaped grooves 8 on the front of the sound insulation panel 7, allows incident sound to be reflected multiple times within the well-shaped grooves 8, thus consuming sound energy. Several hemispherical protrusions 11 are provided on the inner surface of the recess 9, which further scatter sound, increasing the sound propagation path and energy loss. Several arc-shaped grooves 12 are provided on the front of the sound insulation panel 7, and the several well-shaped grooves 8 and several polygonal grooves 10 are arranged alternately. The several well-shaped grooves 8 are located on the outer side of the several recesses 9. The sound insulation panel 7 can be made of materials with good sound absorption properties, such as glass wool and rock wool. These materials themselves have many tiny pores that can effectively absorb sound energy. Combined with the above-mentioned groove structures, the sound insulation effect can be further enhanced.

[0029] like Figure 2 and Figure 3 As shown, the arc-shaped groove 12 is arranged horizontally, and several arc-shaped grooves 12 are arranged vertically at equal intervals. The length of the arc-shaped groove 12 is greater than half the width of the sound insulation board 7. By opening several longer arc-shaped grooves 12, more sound can be reflected and absorbed, thus enhancing the sound insulation performance.

[0030] like Figure 1 As shown, the photovoltaic panel 5 is connected to the outer frame 2 by two symmetrically arranged fastening bolts 13 to ensure the stability of the photovoltaic panel 5 installation.

[0031] like Figure 1 and Figure 5 As shown, the sealing gasket 6 is U-shaped and is installed on the inner surface of the outer frame 2 by adhesive. The outer surface of the photovoltaic panel 5 is in contact with the two sealing gaskets 6. The U-shaped sealing gasket 6 can better wrap the edge of the photovoltaic panel 5, ensuring the sealing performance of the module and effectively preventing sound from spreading from the gap.

[0032] like Figure 5 As shown, the frame body 1 is integrally formed, and the back of the photovoltaic panel 5 is attached to the inner frame 3 and the sound insulation board 7. The integrally formed frame body 1 has a more stable structure.

[0033] The working principle of the above embodiment is as follows: When sound travels to the photovoltaic module, it first contacts the photovoltaic panel 5. Some of the sound passes through the photovoltaic panel 5 and reaches the sound insulation board 7. Through the several well-shaped grooves 8 on the front of the sound insulation board 7, the incident sound can be reflected multiple times in the well-shaped grooves 8, consuming sound energy. The hemispherical protrusions 11 in the multiple notches 9 further scatter the sound, increasing the sound propagation path and energy loss. The combination of multiple polygonal grooves 10 and arc-shaped grooves 12 can also reflect and absorb sound. Through the cooperation between the various groove structures, the sound propagation can be effectively blocked. At the same time, the sealing gasket 6 set between the outer frame 2 and the photovoltaic panel 5 ensures the sealing performance of the module and prevents sound from propagating through gaps, so that the entire photovoltaic module has a good sound insulation effect, which is beneficial to practical use.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
