Sliding seats are provided at the tops of the support arms, and the sliding seats extend into the sliding grooves. Connecting shafts are installed at one ends of the sliding seats close to the support arms, and the sliding seats are connected to the support arms through the connecting shafts. Support arms are provided at the bottoms of the support arms. First connecting shafts are installed at the tops of the support arms, and the support arms are movably connected to the support arms through the first connecting shafts. It realizes the angle-adjustable installation and fixing of the photovoltaic module installation structure in the photovoltaic building integration, facilitates multi-position adjustment and fixing to receive the maximum light rate, and improves the convenience during installation and adjustment.

[0005] The patent publication number is: CN 219740257 U, which discloses a BIPV photovoltaic building integrated installation and fixing structure, including a framework. An adjusting leg is fixedly connected to the lower surface of the framework. Adjusting holes are provided on the outer surface of the adjusting leg.

DETAILED DESCRIPTION OF THE INVENTION

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Please refer to Figures 1 to 6 , an embodiment provided by the present invention: a BIPV photovoltaic building integrated installation and fixing structure, including a house 1, a BIPV photovoltaic building integrated fixing bracket 3 is fixedly installed on the upper end surface of the house 1, and a plurality of solar panels B4 are fixedly installed on both sides of the upper end surface of the BIPV photovoltaic building integrated fixing bracket 3. A snow sweeping mechanism is fixedly installed at the middle position of the upper end surface of the BIPV photovoltaic building integrated fixing bracket 3. The snow sweeping mechanism includes two snow sweeping rollers 7 and a cyclic synchronous transmission mechanism. The two snow sweeping rollers 7 are respectively located on both sides above the BIPV photovoltaic building integrated fixing bracket 3, and the lower end surface of the snow sweeping roller 7 is in contact with the outer surface of the solar panel B4. Through cyclic synchronous transmission, while driving the two snow sweeping rollers 7 to rotate, they can move cyclically on the outer surface of the BIPV photovoltaic building integrated fixing bracket 3.

[0032] The cyclic synchronous transmission mechanism includes a toothed row 5. One side above the toothed row 5 is provided with a metal housing 6 slidably installed on the upper end surface of the BIPV photovoltaic building integrated fixing bracket 3, and a stepping motor 8 is fixedly installed on the upper side inside the metal housing 6;

[0033] An environmental sensor 22 is provided on one side of the toothed row 5, and the environmental sensor 22 is electrically connected to the stepping motor 8; when it snows outside, it will be detected by the environmental sensor 22, and then the stepping motor 8 electrically connected to the environmental sensor 22 will be automatically started accordingly.

[0034] The output shaft of the stepping motor 8 is connected to a transmission rotating shaft 9 through a coupling. A bevel gear A10 is fixedly sleeved on the lower side of the outer surface of the transmission rotating shaft 9. The bevel gear A10 meshes with a bevel gear B11. The axis of the bevel gear B11 is connected to a rotating shaft A12. Synchronous sprockets A13 are fixedly sleeved on both sides of the outer surface of the rotating shaft A12; during the rotation of the stepping motor 8, the transmission rotating shaft 9 connected to the axis of the stepping motor 8 will rotate accordingly. When the transmission rotating shaft 9 rotates, the bevel gear A10 fixedly sleeved on the outer surface of the transmission rotating shaft 9 and the bevel gear B11 meshing with it will rotate together. The rotating bevel gear B11 will drive the rotating shaft A12 connected to the axis of the bevel gear B11 and the two synchronous sprockets A13 fixedly sleeved on the outer surface of the rotating shaft A12 to rotate.

[0035] Below each of the two synchronous sprockets A13, there is provided a synchronous sprocket B15. The two synchronous sprockets A13 and the two synchronous sprockets B15 are respectively connected in series by a synchronous chain 16. When the synchronous sprocket A13 rotates, the synchronous sprocket B15 connected in series with it through the synchronous chain 16 will rotate together.

[0036] A rotating shaft B14 is connected to the axles of the two synchronous sprockets B15. In the middle position of the outer surface of the rotating shaft B14, a gear 20 meshing with the tooth row 5 is fixedly sleeved. The rotating synchronous sprocket B15 will drive the rotating shaft B14 connected to the axle of the synchronous sprocket B15 and the gear 20 fixedly sleeved in the middle position of the outer surface of the rotating shaft B14 to rotate. When the gear 20 rotates, due to the meshing connection with the tooth row 5, the metal shell 6 slidably mounted on the upper end surface of the BIPV photovoltaic building integration fixing bracket 3 will move along the tooth row 5. And with the forward and reverse rotation of the transmission rotating shaft 9, the metal shell 6 will move back and forth on the tooth row 5.

[0037] On both sides of the outer surface of the rotating shaft B14, a bevel gear C17 is fixedly sleeved. The bevel gear C17 meshes with a bevel gear D18. The axle of the bevel gear D18 is connected to a roller rotating shaft 19. The two roller rotating shafts 19 are respectively fixed to the two snow-sweeping rollers 7. And the other end of the snow-sweeping roller 7 is connected to a slider connection block 21 slidably mounted on the upper end surface of the house 1. When the rotating shaft B14 rotates, the bevel gear C17 fixedly sleeved on the outer surface of the rotating shaft B14 and the bevel gear D18 meshing with it will rotate together. The rotating bevel gear D18 will drive the roller rotating shaft 19 connected to the axle of the bevel gear D18 and the snow-sweeping roller 7 fixed to the roller rotating shaft 19 to rotate. During the rotation of the snow-sweeping roller 7, it will be pulled by the indirectly connected metal shell 6 to move together. By the snow-sweeping roller 7 rotating and moving at the same time, the snow accumulated on the solar panel B4 can be swept down to prevent it from covering the solar panel B4. Through the above technical solution, the power generation efficiency of the device in winter is ensured.

[0038] A solar panel expansion mechanism 2 is installed on the outer surface of the BIPV photovoltaic building integration fixing bracket 3. The solar panel expansion mechanism 2 includes a strip-shaped installation groove 201, an L-shaped clamping plate A202, a rotating shaft connecting plate 203, an L-shaped fixing base 204, a solar panel fixing plate 206, an L-shaped clamping plate B207, and a solar panel A209. The L-shaped clamping plate A202 is clamped inside the strip-shaped installation groove 201. The rotating shaft connecting plate 203 is connected to the lower end surface of the L-shaped clamping plate A202 through a rotating shaft. The L-shaped fixing base 204 is connected to the lower end surface of the rotating shaft connecting plate 203 through a rotating shaft. The L-shaped clamping plate B207 is fixed to the upper end surface of the solar panel fixing plate 206. The shape of the top end of the L-shaped clamping plate B207 corresponds to the shape of the inner wall of the L-shaped fixing base 204. And the solar panel A209 is fixed inside the solar panel fixing plate 206.

[0039] The solar panel expansion mechanism 2 further includes two bolt fixing through holes 205, which are respectively located on both sides of the outer surface of the L-shaped fixing base 204. Below the two bolt fixing through holes 205, there is an L-shaped connecting base 208 fixed to the lower end surface of the solar panel fixing plate 206, and the shape of the inner wall of the L-shaped connecting base 208 corresponds to the shape of the top end of the L-shaped clamping plate B207. When installing the solar panel A209, first buckle the L-shaped clamping plate A202 into the inside of the strip-shaped installation groove 201 and use bolts to fix the L-shaped clamping plate A202. After the L-shaped clamping plate A202 is fixed, pick up the L-shaped fixing base 204 connected to the bolt fixing through hole 205 through the rotating shaft connecting plate 203, and make the surface of the L-shaped fixing base 204 facing the house 1 fit against the outer surface of the house 1. After the L-shaped fixing base 204 and the house 1 are mutually fitted, fix the L-shaped fixing base 204 on the wall surface of the house 1 through the bolt fixing through hole 205 located on the outer surface of the L-shaped fixing base 204. After the L-shaped fixing base 204 is fixed, pick up the solar panel fixing plate 206 with the solar panel A209 fixed inside, and snap the L-shaped clamping plate B207 fixed to the upper end surface of the solar panel fixing plate 206 into the inside of the L-shaped fixing base 204.

[0040] On both sides of the outer surface of the solar panel fixing plate 206, there is a bolt fixing groove 210, and on both sides inside the bolt fixing groove 210, there is a bolt fixing hole penetrating through the solar panel fixing plate 206. After snapping the L-shaped clamping plate B207 into the inside of the L-shaped fixing base 204, fix the solar panel fixing plate 206 on the wall surface through the bolt fixing hole. If there is still a large distance between the lower end surface of this solar panel fixing plate 206 and the ground after fixing one solar panel fixing plate 206, you can pick up another solar panel fixing plate 206 and snap the L-shaped clamping plate B207 fixed to the upper end surface of this solar panel fixing plate 206 into the inside of the L-shaped connecting base 208 at the lower end surface of the solar panel fixing plate 206 that has been fixed to the wall surface. Then, fix the newly installed solar panel fixing plate 206 through bolts until the distance between the lower end surface of the lowermost solar panel fixing plate 206 and the ground no longer allows the installation of a new solar panel fixing plate. Through the above technical solution, the solar panel A209 can be installed on the side of the house 1, increasing the maximum installation quantity of the solar panels, thereby improving the overall power generation rate of the device;

[0041] When installing the solar panel A209, do not install it at the window opening on the outer surface of the house 1 to prevent affecting its lighting;

[0042] On both sides of the front end face of the solar panel fixing plate 206, there is a connection through hole 211 penetrating the solar panel fixing plate 206. Behind each of the two connection through holes 211, there is a connection threaded rod 212. In front of and behind the connection threaded rod 212, there is a fixing nut 213 respectively; when a new row of solar panels A209 needs to be installed, pick up a new L-shaped clamping plate A202 and fix this L-shaped clamping plate A202 behind the already fixed L-shaped clamping plate A202, and ensure that they fit together. After the new row of solar panels A209 is fixed, pass the connection threaded rod 212 through the connection through hole 211 on the outer surface of the solar panel fixing plate 206 in the same row. Then, sleuth the two fixing nuts 213 respectively on both sides of the outer surface of the connection threaded rod 212, and ensure that the two fixing nuts 213 can respectively fit against one side between the two solar panel fixing plates 206 to fix them. Through the above technical solution, the stability and strength between the multiple installed solar panel fixing plates 206 can be increased.

[0043] Above the stepping motor 8, there is a metal cover plate located on the upper end face of the metal housing 6, and the metal housing 6 and the metal cover plate are fixed by screws; the metal cover plate can protect the stepping motor 8, and when the stepping motor 8 fails, the metal cover plate can be removed for maintenance.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
