However, on rainy days, the noise generated by rain hitting the photovoltaic panels is relatively large. When they are laid on the roofs of houses and awnings, they seriously affect the daily life of users. At the same time, this shortcoming is also one of the reasons that hinder the large-scale popularization of photovoltaic building integration structures. In response to the above problems, this application is proposed. Summary of the Invention

[0027] The following combination Figure 1-9 The present invention will be described in detail.

[0028] The noise reduction photovoltaic building integrated structure of the present invention includes a frame 1, such as Figure 1 The frame 1 is provided with a photovoltaic panel mounting position 12, and the photovoltaic panel 3 is mounted in the photovoltaic panel mounting position 12. The frame 1 is provided with a first receiving groove 10 and a second receiving groove 11, and two second receiving grooves 11 are provided. The first receiving groove 10 and the second receiving groove 11 are respectively arranged on adjacent sides of the photovoltaic panel 3. The first receiving groove 10 is arranged on one side in the length direction of the photovoltaic panel 3, and the second receiving groove 11 is arranged on one side in the width direction of the photovoltaic panel 3. A shielding net 4 is provided in the first receiving groove 10. The longer first receiving groove 10 can accommodate a larger shielding net 4. A cover plate 101 is provided at the opening of the first receiving groove 10. The side of the cover plate 101 is provided with ridges to increase the friction between the cover plate 10 and the inner wall of the first receiving groove 10, so that it is not easily opened automatically due to vibration, wind, etc. in a natural state. One end of the shielding net 4 is connected to the cover plate 101 . A guide rail assembly 111 is provided in the second receiving slot 11 . The guide rail assembly 111 is rotatably installed in the second receiving slot 11 .

[0029] Multiple frames 1 are spliced ​​to form a roof, awning and other buildings. On rainy days, the guide rail assembly 111 is rotated out from the second receiving groove 11. The guide rail assembly 111 includes a screw rod 112 and a slide 113. The slide 113 is provided with a clamping block 1131. The cover plate 101 is provided with a sliding groove 1011. The width of the sliding groove 1011 is greater than the width of the clamping block 1131. Figure 4 After the guide rail assembly 111 is rotated to a vertical state or rotated out of a certain angle from the second receiving slot 11, the clamping block 1131 slides into the sliding slot 1011. Figure 5 , then the slide 113 in the guide rail assembly 111 drives the cover plate 101 to move along the guide rail assembly 111 to pull out the shielding net 4, and make the shielding net 4 cover the photovoltaic panel, thereby forming a buffer for raindrops and achieving the effect of noise reduction. When the noise reduction function is turned off, since the shielding net occupies a small space, once there is debris stored at the same time, it will lead to unsuccessful storage and increase maintenance costs. In this application, the guide rail assembly 111 is quickly rotated to a vertical state during storage, and in the vertical state, the shielding net 4 is stored back into the first storage groove 10, thereby avoiding the debris that falls on the surface of the photovoltaic panel and the shielding net. The storage solves the problem of loud noise in rainy days while the photovoltaic building integrated component does not affect the power generation effect.

[0030] When the shielding net needs to be replaced, since the cover plate 101 is not connected to other components when the shielding net is stored, the cover plate 101 can be easily removed to replace the shielding net.

[0031] Preferably, if Figure 2 A net rolling shaft 102 is provided in the first storage slot 10, and the shielding net 4 is rolled on the net rolling shaft 102. The volume of the first storage slot 10 is smaller than that of the shielding net 4. The shielding net 4 is elastic. When the shielding net 4 is stored back into the first storage slot 10, the net rolling shaft 102 rotates to forcefully retract the shielding net 4, so that the shielding net 4 is compressed and stored in the first storage slot 10, further saving occupied space.

[0032] like Figure 3 、 Figure 6 The guide rail assembly 111 is installed in the second receiving groove 11 through the rotating shaft 114.

[0033] The frame 1 is provided with a power mechanism for driving the net-rolling shaft 102 to rotate. The power mechanism drives the rotating shaft 114 to rotate so as to rotate the guide rail assembly 111 . The screw rod 112 is connected to the power mechanism via a transmission assembly 21 .

[0034] The power mechanism includes a driving shaft 2, the rotating shaft 114 and the net-winding shaft 102 are both hollow shafts, the driving shaft 2 passes through the rotating shaft 114 and the net-winding shaft 102, and a plurality of telescopic key assemblies 22 are provided on the driving shaft 2, and the connection or separation of the driving shaft 2 with the rotating shaft 114 and the net-winding shaft 102 is realized through the telescopic key assemblies 22. The telescopic key assembly 22 is an electric telescopic structure or a hydraulic telescopic structure, such as an electric telescopic rod, a hydraulic telescopic rod, etc. When the guide rail assembly 111 rotates, the telescopic key assembly 22 extends out and connects with the rotating shaft 114. When the net-winding shaft 102 needs to store the shielding net, the telescopic key assembly 22 extends out and connects with the net-winding shaft 102 to realize transmission.

[0035] The telescopic key assembly 22 and other electrical devices are uniformly controlled by a programmable control assembly, such as a computer or a PLC device.

[0036] The transmission assembly 21 is a bevel gear structure, such as Figure 6 The transmission of the driving shaft 2 to the screw rod 112 is realized through two bevel gears.

[0037] Both ends of the driving shaft 2 can be connected to the driving shafts 2 in the remaining frames, and a horizontal frame can use one motor to drive the driving shaft 2.

[0038] Preferably, the surfaces of the cover plate 101 and the guide rail assembly 111 are flush with the surface of the frame 1 .

[0039] Preferably, the shielding net 4 is made of low-density polyethylene or nylon.

[0040] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
