This technology can organically combine the building roof with the photovoltaic power generation function, and becomes one of the key technologies to promote the development of green energy.
[0003] The traditional solar photovoltaic power generation system is generally installed on the ground or a special support. This mode has obvious disadvantages: not only the valuable land resources are occupied, but also the visual incoordination is caused. In comparison, the photovoltaic building integrated roof technology has unique advantages, which ingeniously integrates the photovoltaic module with the building roof, fully utilizes the space of the building roof, and makes the building appearance more beautiful and harmonious. Specifically, the technology realizes the function of converting solar energy into electric energy by installing the photovoltaic module on the building roof.
[0004] However, the traditional photovoltaic building integrated technology also faces many challenges in practical application. First, it usually installs the photovoltaic module at a fixed angle. Moreover, when encountering hail and other severe weather, due to the limitation of structural design and fixing mode, the photovoltaic module is easily broken by hail, thereby threatening the building safety and personnel safety. This situation not only causes the damage of the photovoltaic system, but also may cause serious economic loss and safety hidden danger. SUMMARY

First, it usually installs the photovoltaic module at a fixed angle. Moreover, when encountering hail and other severe weather, due to the limitation of structural design and fixing mode, the photovoltaic module is easily broken by hail, thereby threatening the building safety and personnel safety. This situation not only causes the damage of the photovoltaic system, but also may cause serious economic loss and safety hidden danger.
[0006] In order to achieve the above purpose, the present application adopts the following technical scheme: a photovoltaic building integrated roof: comprising a plurality of bases installed on a bottom plate, further comprising: a turnover assembly arranged on the base, and the bottom plate, the base and the turnover assembly constitute an integrated roof. The turnover assembly comprises a support base fixed on the base, a rotating plate connected with a rotating shaft through internal rotation connection, and photovoltaic tiles installed on the rotating plate.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0018] As Figures 1-10As shown, the photovoltaic building integrated roof provided by the present application comprises a plurality of bases 10 installed on a bottom plate, further comprises: a turnover assembly 20 arranged on the base 10, the turnover assembly 20 comprises a support seat 21 fixed on the base 10, the support seat 21 is connected with a rotating plate 221 through an internal rotating connection rotating shaft 22, the rotating plate 221 is connected with a photovoltaic tile through structural glue, the surface of the rotating plate 221 is finely pretreated to enhance the adhesion performance with the structural glue, then high-performance silicone structural glue is used to uniformly and continuously glue the photovoltaic tile on the rotating plate 221, this connection mode not only ensures that the photovoltaic tile and the rotating plate 221 have very high adhesion strength, can effectively resist various stresses of external environment such as wind force, vibration, etc., one side of the support seat 21 is fixed with an extension frame 23, the outer periphery of the rotating shaft 22 is provided with a slot 222, and the inner wall of the slot 222 is slidably connected with a limiting block 223, the outer periphery of the limiting block 223 is fixed with a rotating gear 224 and a half gear 225 away from each other, the number of gears of the half gear 225 is adjusted according to actual use, and is not fixed as half of the full gear, the outer wall of the extension frame 23 is fixed with an extension plate 24 and a mounting frame 25 away from each other, and the outer wall of the extension frame 23 and the extension plate 24 is rotatably connected with a double-sided gear belt 26 engaged with the rotating gear 224 and the half gear 225, the inner wall of the double-sided gear belt 26 extends into the extension frame 23 and the extension plate 24, the extension plate 24 is provided with an avoiding slot avoiding the inner wall gear of the double-sided gear belt 26, one side of the mounting frame 25 is provided with a driving part, the driving part comprises a servo motor 251 mounted on one side of the mounting frame 25, the output end of the servo motor 251 is connected with a main gear 252 through the mounting frame 25, and the main gear 252 is engaged with the double-sided gear belt 26; In the initial state, the photovoltaic tiles on the rotating plates 221 are sequentially stacked and placed as shown, Figure 2 If hail weather is encountered in the initial state, the photovoltaic tiles on the rotating plates 221 are still arranged upward, and the impact force of the hail will cause damage to the photovoltaic tiles; Therefore, when encountering hail weather, it is necessary to adjust the position of the photovoltaic tile to face down to avoid hail impact. By starting the servo motor 251, the servo motor 251 drives the main gear 252 to rotate together. With the rotation of the main gear 252, the double-sided gear belt 26 is driven to rotate, and the double-sided gear belt 26 further drives the rotating gear 224 to rotate to the left, and simultaneously drives the rotating shaft 22 to rotate. With the rotation of the rotating shaft 22, the photovoltaic tile on one side of the rotating plate 221 is flipped down. At this time, the rotating plate 221 with a higher height is stacked on the rotating plate 221 with a lower height in turn, so that the plurality of rotating plates 221 are arranged in a descending stepped manner. This arrangement can play a protective role for the photovoltaic tile. At the same time, since the plurality of rotating plates 221 are arranged in a descending manner, the falling hail will slide down along the inclined surface of the rotating plate 221 and will not accumulate on the surface of the rotating plate 221, thereby avoiding the support of the support seat 21. When it is necessary to remove the protection of the photovoltaic tile and restore its normal work, only the servo motor 251 needs to be started in reverse. The servo motor 251 drives the main gear 252 to rotate in reverse, thereby driving the double-sided gear belt 26 to rotate. The double-sided gear belt 26 drives the rotating gear 224 to rotate to the right, simultaneously driving the rotating shaft 22 to rotate, so that the photovoltaic tile on one side of the rotating plate 221 is flipped up, restoring the normal working state of the photovoltaic tile.
[0019] As shown in Figure 1 , Figure 3 , Figure 5 , Figure 6 , the inner wall of the extension frame 23 is provided with a pushing assembly 30. The pushing assembly 30 includes a fixed plate 31 fixed to the inner wall of the extension frame 23 and a circular ring 34 fixed to the side of the half gear 225 away from the rotating gear 224. One side of the fixed plate 31 is provided with an electric push rod 32, and the extension end of the electric push rod 32 is fixedly connected with a pushing plate 33. The inside of the circular ring 34 is provided with an embedded groove 341, and the pushing plate 33 is movably embedded in the embedded groove 341. When the circular ring 34 rotates, the pushing plate 33 is still embedded in the embedded groove 341 and will not cause obstruction. When encountering hail weather, not only hail will fall on the back surface of the rotating plate 221, but also leaves and other debris will be blown into the inside surface of the rotating plate 221. The accumulation of leaves and other debris can cause some hail to stay on the back surface of the rotating plate 221 and further accumulate, which can affect the support of the support seat 21. To solve this problem, the electric push rod 32 can be started, the electric push rod 32 pushes the push plate 33, because the push plate 33 is embedded in the ring 34, the push plate 33 will push the ring 34, and then make the ring 34 drive the half gear 225 and the limiting block 223 move, with the movement of the limiting block 223, the rotating gear 224 will also move synchronously, so that the rotating gear 224 is disengaged from the meshing state with the double-sided gear belt 26, with the electric push rod 32 continuing to extend, the half gear 225 will engage with the double-sided gear belt 26; When the half gear 225 engages with the double-sided gear belt 26, the servo motor 251 is started in reverse, the servo motor 251 drives the main gear 252 to rotate together, with the rotation of the main gear 252, the double-sided gear belt 26 is driven to rotate, the double-sided gear belt 26 drives the half gear 225 to rotate to the right, because the plurality of rotating plates 221 are inclinedly arranged, under the influence of their own weight and gravity, the half gear 225 is always in the downward rotating trend, when the double-sided gear belt 26 moves and contacts the downward half gear 225, it will drive the half gear 225 to rotate the rotating shaft 22, with the rotation of the rotating shaft 22, the rotating plate 221 will slightly swing upward, so that the accumulated material on the back surface of the rotating plate 221 is shaken off.
[0020] As shown in Figure 1 , Figure 3 , Figure 8 , Figure 9 , Figure 10 The base 10 is provided with a buffer assembly 40, the buffer assembly 40 includes a clamping plate 41 fixed between the inner walls of the base 10, the top of the clamping plate 41 is fixed with an extension block 42, and the inner wall of the extension block 42 is slidably connected with a sliding rod 421, one side of the sliding rod 421 is fixed with a contact plate 422 in contact with the rotating gear 224, the bottom of the sliding rod 421 is fixed with a plurality of first gear teeth 423, one side of the extension block 42 is fixed with a positioning column 43, the bottom of the sliding rod 421 is fixed with an extrusion plate 431, the outer periphery of the positioning column 43 is sleeved with a first spring 432 in contact with the extrusion plate 431, the base 10 is fixed with a connecting plate 44, and one side of the connecting plate 44 close to the extension block 42 is fixed with an extension cylinder 45, the inner wall of the extension cylinder 45 is rotatably connected with a rotating rod 46, and the outer periphery of the rotating rod 46 is connected with a plurality of second gear teeth 461 engaged with the first gear teeth 423, the outer periphery of the extension cylinder 45 is provided with a limiting groove 451, the outer periphery of the rotating rod 46 is fixed with a clamping rod 47 in contact with the limiting groove 451, and the inner wall of the clamping rod 47 is provided with an inner cavity 471, the inner wall of the inner cavity 471 is slidably connected with a buffer column 473 in contact with the photovoltaic tile, the length of each buffer column 473 is adjusted according to different heights, and the second spring 472 is connected between the buffer column 473 and the inner cavity 471; In the above operation process, as the rotating gear 224 moves, it will move synchronously with the contact plate 422, when the contact plate 422 moves, it will drive the sliding rod 421 to move, at this time, the first gear teeth 423 at the bottom of the sliding rod 421 will drive the second gear teeth 461, and then make the second gear teeth 461 drive the rotating rod 46 to rotate in the extension cylinder 45; At the same time, as the sliding rod 421 moves, the extrusion plate 431 at the bottom of the sliding rod 421 will slide along the outer periphery of the positioning column 43 and extrude the first spring 432, as the rotating rod 46 rotates, it will drive the clamping rod 47 to move in the limiting groove 451, so that the clamping rod 47 changes from a horizontal state to a vertical state, when the clamping rod 47 moves to the vertical state, the rotating plate 221 swings slightly upward, and then falls under the influence of its own weight and gravity, at this time, the rotating plate 221 will contact the buffer column 473, and the buffer column 473 will extrude the second spring 472, through the buffering effect of the second spring 472, the falling of the rotating plate 221 can be buffered, reducing the damage to the photovoltaic tile and improving the protection effect of the photovoltaic tile; When it is needed to switch to the full tooth state, the electric push rod 32 is started, the electric push rod 32 pulls the pushing plate 33, because the pushing plate 33 is embedded in the circular ring 34, so the circular ring 34 will be pulled, and then the circular ring 34 drives the half gear 225 and the limiting block 223 to move, as the limiting block 223 moves, the rotating gear 224 will move synchronously, so that the half gear 225 is disengaged from the meshing state with the double-sided gear belt 26, as the electric push rod 32 contracts, the rotating gear 224 will engage with the double-sided gear belt 26. At the same time, as the rotating gear 224 moves, the first spring 432 in the extrusion state will rebound, pushing the extrusion plate 431 to reset, the extrusion plate 431 drives the sliding rod 421 to move, so that the first gear teeth 423 drive the second gear teeth 461, and the second gear teeth 461 drive the rotating rod 46 to rotate, so that the clamping rod 47 switches from the vertical state to the horizontal state.
[0021] Working principle: in the initial state, the photovoltaic tiles on the rotating plates 221 are stacked in sequence, if at this time it encounters hail weather, and the photovoltaic tiles are still upward, the impact force of the hail will cause damage to them, therefore, the position of the photovoltaic tiles needs to be adjusted to downward to avoid impact in the hail weather, the servo motor 251 is started, driving the main gear 252 to rotate, and then driving the double-sided gear belt 26 to rotate, the double-sided gear belt 26 drives the rotating gear 224 to rotate to the left, so that the rotating shaft 22 rotates, and the photovoltaic tiles on one side of the rotating plate 221 are turned downward, the rotating plates 221 with high height are stacked on the rotating plates 221 with low height, and are arranged in a descending step type, which can not only protect the photovoltaic tiles, but also make the hail slide down along the inclined rotating plate 221, avoiding the accumulation to affect the support of the support seat 21; When it is hail weather, the hail will drop on the back of the rotating plate 221, and the wind will also blow the leaves and other sundries into the inside of the rotating plate 221. The accumulation of the sundries will make the hail further accumulate, and affect the supporting property of the supporting seat 21. In order to solve this problem, the electric push rod 32 is started, and the pushing plate 33 is abutted and pushed. Because the pushing plate 33 is embedded in the ring 34, the ring 34, the half gear 225 and the limiting block 223 will be moved, so that the rotating gear 224 is disengaged from the meshing with the double-sided gear belt 26. The electric push rod 32 continues to extend, the half gear 225 meshes with the double-sided gear belt 26, the servo motor 251 is started in reverse, the main gear 252 is rotated, the double-sided gear belt 26 is driven to rotate, the half gear 225 is rotated to the right, because the rotating plate 221 is inclined, the half gear 225 has a downward rotating trend, when the double-sided gear belt 26 moves to contact the half gear 225, it will drive the rotating shaft 22 to rotate, so that the rotating plate 221 slightly swings upward, and the back accumulated material is shaken off. In operation, the movement of the rotating gear 224 abuts against the contact plate 422, drives the sliding rod 421 to move, the first gear teeth 423 at the bottom of the sliding rod 421 drive the second gear teeth 461, so that the rotating rod 46 rotates in the extension cylinder 45. At the same time, the movement of the sliding rod 421 makes the pressing plate 431 slide along the positioning column 43 and press the first spring 432. The rotation of the rotating rod 46 drives the clamping rod 47 to move in the limiting groove 451, and changes from horizontal to vertical state. After the clamping rod 47 is vertical, the rotating plate 221 slightly swings upward and falls, contacts the buffer column 473 and presses the second spring 472. The buffer of the second spring 472 can reduce the damage to the photovoltaic tile, and improve the protection effect.
[0022] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
