[0004] However, the current photovoltaic modules are tightly spliced, and when it rains, the rain will wash the bird droppings and other debris on the surface of the upper photovoltaic module downward. The rainwater mixed with debris flows through the lower photovoltaic module, and finally falls off from the roof. In this process, the photovoltaic module in the lower layer always needs to withstand the scouring of the upper layer debris, causing continuous flow scouring damage to the photovoltaic module on the roof, increasing the plating film wear rate of the module surface by 30%, and reducing the power generation efficiency by 15%-20%. Therefore, further improvement can be made. SUMMARY

Similarly, when it rains, the driving unit drives the Z-shaped rotating shafts to rotate reversely, so that the Z-shaped rotating shafts drive the photovoltaic modules to be downwardly turned closed, so that the external rainwater is not easy to enter the indoor. In addition, when the surface of the photovoltaic module is accumulated with sundries such as sand and snow, the driving unit drives the Z-shaped rotating shafts to continuously rotate, at this time, the Z-shaped rotating shafts drive the photovoltaic modules to continuously and periodically swing, so as to shake off the sundries on the surface of the photovoltaic module into the horizontal groove beam, then into the vertical groove beam through the horizontal groove beam, and finally drop out of the roof through the vertical groove beam.

[0022] By adopting the above technical scheme, when the photovoltaic module is installed, the torsion spring on the rotating shaft of the hinged seat is used to rotate and abut the bottom of the waterproof board to the inside of the horizontal groove beam, so as to block the gap between the top of the bottom surface of the photovoltaic module and the horizontal groove beam, so that the water or sundries falling into the horizontal groove beam is not easy to fall into the room through the gap between the top of the bottom surface of the photovoltaic module and the horizontal groove beam. At the same time, the waterproof board covers the locking screw, which can protect the locking screw and delay the rusting and damage of the locking screw.

[0042] The embodiment of the application discloses a photovoltaic integrated building structure.

[0043] Refer to Figure 1 The photovoltaic integrated building structure comprises a roof mounting frame 1 and a photovoltaic module 2 in the form of a square plate, and the roof mounting frame 1 is arranged to be inclined downward, and the photovoltaic module 2 is arranged to be laid on the top of the roof mounting frame 1.

[0044] Specifically, in the embodiment, the roof mounting frame 1 comprises a plurality of U-shaped longitudinal channel beams 11 arranged with openings upward, the plurality of longitudinal channel beams 11 are arranged to be parallel to each other and uniformly spaced in the transverse direction, and each longitudinal channel beam 11 is arranged to be inclined downward in the longitudinal direction. A plurality of transverse channel beams 12 arranged with openings upward are arranged between the adjacent two longitudinal channel beams 11, the plurality of transverse channel beams 12 are arranged on the top of the longitudinal channel beams 11, and the plurality of transverse channel beams 12 are arranged to be spaced along the length direction of the longitudinal channel beams 11, so that the adjacent two transverse channel beams 12 and the corresponding longitudinal channel beams 11 can form a mounting opening 13 for the photovoltaic module 2. The photovoltaic module 2 is arranged to be laid on the mounting opening 13, the adjacent two photovoltaic modules 2 are arranged to be spaced, and the side edge of each photovoltaic module 2 extends to the corresponding longitudinal channel beam 11 or transverse channel beam 12.

[0045] When the rainwater washes the bird droppings and other sundries on the surface of the upper photovoltaic module 2 downward, the washed sundries directly flow into the transverse channel beam 12 below with the rainwater, then flow into the longitudinal channel beam 11 through the transverse channel beam 12 for confluence, and finally flow out of the roof through the longitudinal channel beam 11. In this process, the sundries on the surface of the upper photovoltaic module 2 are not easy to be washed to the surface of the lower photovoltaic module 2, so that the sundries on the upper layer are not easy to cause continuous flow washing damage to the photovoltaic module 2 on the roof, and the cleanliness of the roof can be better maintained.

[0046] Refer to Figure 2 and 3Specifically, in the embodiment, the top of the bottom surface of the photovoltaic module 2 is hinged to the upper horizontal groove beam 12, and the bottom of the bottom surface of the photovoltaic module 2 is supported on the lower horizontal groove beam 12.

[0047] With reference to Figure 4 and Figure 5 Specifically, the two sides of the bottom of the bottom surface of the photovoltaic module 2 are fixed with slide rails 21, the two slide rails 21 are arranged in parallel with each other, and each slide rail 21 extends towards the top of the photovoltaic module 2. A sliding seat 22 is slidingly installed on the slide rail 21, and at this time the sliding seat 22 can be slidingly adjusted from the bottom to the top of the photovoltaic module 2. The bottom of the sliding seat 22 is fixed with a push rod 23, the bottom of the push rod 23 is rotatably installed with a Z-shaped rotating shaft 24, the end of the Z-shaped rotating shaft 24 away from the sliding seat 22 is rotatably connected to the outer side wall of the longitudinal groove beam 11, and the rotating axis between the Z-shaped rotating shaft 24 and the push rod 23 is arranged in parallel with the photovoltaic module 2, and the rotating axis between the Z-shaped rotating shaft 24 and the push rod 23 is perpendicular to the slide rail 21, so that the Z-shaped rotating shaft 24 can drive the photovoltaic module 2 to be upwardly flipped open or downwardly flipped closed by rotating. The roof mounting frame 1 is installed with a driving unit 3 at a position corresponding to each column of photovoltaic modules 2, and the driving unit 3 is used to drive the Z-shaped rotating shaft 24 in the same column of photovoltaic modules 2 to rotate.

[0048] In the normal use process, the driving unit 3 drives the Z-shaped rotating shaft 24 to rotate forwardly, so that the Z-shaped rotating shaft 24 drives the photovoltaic module 2 to be upwardly flipped open, so as to ventilate the indoor and outdoor. Similarly, when it is raining, the driving unit 3 drives the Z-shaped rotating shaft 24 to rotate reversely, so that the Z-shaped rotating shaft 24 drives the photovoltaic module 2 to be downwardly flipped closed, so that the external rainwater is not easy to enter the indoor. In addition, when the surface of the photovoltaic module 2 is accumulated with sand, snow and other sundries, the driving unit 3 drives the Z-shaped rotating shaft 24 to continuously rotate, at this time the Z-shaped rotating shaft 24 drives the photovoltaic module 2 to continuously and periodically swing, so as to shake off the sundries on the surface of the photovoltaic module 2 into the horizontal groove beam 12, then the horizontal groove beam 12 is converged into the longitudinal groove beam 11, and finally the longitudinal groove beam 11 is dropped off the roof.

[0049] With reference to Figure 2 and Figure 6 Specifically, in the embodiment, the top of the bottom surface of the photovoltaic module 2 is hinged to the upper horizontal groove beam 12, and the bottom of the bottom surface of the photovoltaic module 2 is supported on the lower horizontal groove beam 12.

[0050] In the process of installing the photovoltaic assembly 2, the worker first inserts the inverted U-shaped buckle plate 4 into the top of the side wall of the horizontal groove beam 12, and then locks and fixes the inverted U-shaped buckle plate 4 through the locking screw 43, so as to articulate the top of the bottom surface of the photovoltaic assembly 2 to the upper horizontal groove beam 12, facilitating the worker to complete the installation work of the photovoltaic assembly 2. Similarly, when the photovoltaic assembly 2 needs to be disassembled and repaired due to damage, the worker can loosen the locking screw 43 to release the connection between the top of the photovoltaic assembly 2 and the horizontal groove beam 12, facilitating the worker to complete the disassembly and repair work of the photovoltaic assembly 2.

[0051] Specifically, the first articulating seat 41 is fixedly installed on both sides of the top of the bottom surface of the photovoltaic assembly 2, and correspondingly, the second articulating seat 42 is fixedly installed on both sides of the top of the inverted U-shaped buckle plate 4, and the two first articulating seats 41 are respectively rotationally connected to the two second articulating seats 42, so that the inverted U-shaped buckle plate 4 is articulated to the top of the bottom surface of the photovoltaic assembly 2.

[0052] Referring to Figure 3 and Figure 5 , specifically, in the embodiment, the driving unit 3 includes a driving motor 31, a transmission chain 32, and a first transmission sprocket 33; wherein the number of the first transmission sprocket 33 is multiple, and the multiple first transmission sprockets 33 are respectively arranged one by one corresponding to the multiple photovoltaic assemblies 2; each first transmission sprocket 33 is fixedly sleeved and installed at the end of the right Z-shaped rotating shaft 24 away from the photovoltaic assembly 2, and the multiple first transmission sprockets 33 are located in the same plane. The driving motor 31 is fixedly installed on the outer side wall of the right longitudinal groove beam 11, and a driving sprocket 34 is fixedly installed on the motor shaft of the driving motor 31, and the driving sprocket 34 is located in the same plane as the transmission sprocket. The transmission chain 32 is simultaneously meshingly connected to the driving sprocket 34 and the transmission sprocket, so that the driving motor 31 can drive the multiple transmission sprockets to rotate simultaneously through the driving sprocket 34 and the transmission chain 32.

[0053] When the surface of the photovoltaic assembly 2 is accumulated with sand, snow and other sundries, the driving motor 31 drives the driving sprocket 34 to rotate, and the driving sprocket 34 drives the multiple transmission sprockets to rotate simultaneously through the transmission chain 32, so as to control the Z-shaped rotating shaft 24 in the same column of photovoltaic assemblies 2 to rotate, and further control the photovoltaic assembly 2 to rotate and swing.

[0054] Referring to Figure 4 , in the embodiment, the sliding seat 22 is also articulated with a telescopic rod 5, and the end of the telescopic rod 5 away from the sliding seat 22 is articulated to the lower horizontal groove beam 12. During the swinging of the photovoltaic assembly 2, due to the arrangement of the telescopic rod 5, the telescopic rod 5 can further guide the swinging of the photovoltaic assembly 2, and further prevent the photovoltaic assembly 2 from shaking, so as to further improve the swinging stability of the photovoltaic assembly 2.

[0055] Referring to Figure 7Specifically, in the embodiment, the cross-groove beam 12 has an isosceles trapezoidal cross-sectional profile, and the cross-groove beam 12 continuously narrows from top to bottom, so that the top opening of the cross-groove beam 12 is relatively large, which is conducive to the collection of rainwater and sundries. Meanwhile, the sundries falling into the cross-groove beam 12 can continuously fall to the bottom of the cross-groove beam 12 for accumulation.

[0056] With reference to Figure 5 and Figure 7 , the bottom of the cross-groove beam 12 is provided with a material pushing opening 121 extending through the bottom of the cross-groove beam 12. A material pushing soft film 122 is fixedly installed on the inner bottom surface of the cross-groove beam 12 and is in a relaxed state. A material pushing roller 123 is installed at a position of the bottom of the cross-groove beam 12 in alignment with the material pushing opening 121. Two roller seats are fixed to the bottom of the cross-groove beam 12, and the material pushing roller 123 is rotatably installed at two ends of the material pushing roller 123. A spiral material pushing blade 124 is fixed to the material pushing roller 123 and supports the material pushing soft film 122.

[0057] When the driving motor 31 drives the photovoltaic module 2 to continuously and periodically swing through the transmission chain 32, the first transmission sprocket 33 and the Z-shaped rotating shaft 24, the driving motor 31 drives the material pushing roller 123 to rotate through the transmission chain 32 and the second transmission sprocket 125 at the same time, so that the spiral material pushing blade 124 on the material pushing roller 123 pushes the sundries in the cross-groove beam 12 into the longitudinal groove beam 11 along the length direction of the cross-groove beam 12, so that the sundries are not easily accumulated and blocked in the cross-groove beam 12.

[0058] In the embodiment, the number of the spiral material pushing blades 124 is two, and the two spiral material pushing blades 124 are fixedly installed at two ends of the material pushing roller 123, and the rotation directions of the two spiral material pushing blades 124 are opposite. During the process of pushing the sundries, the two spiral material pushing blades 124 can push the sundries on both sides of the cross-groove beam 12 to the two longitudinal groove beams 11, which is conducive to the pushing and moving of the sundries.

[0059] With reference to Figure 6 and Figure 8In the embodiment, the waterproof plate 6 is hingedly installed on the top side of the photovoltaic module 2. Specifically, two first hinged ears 61 are fixed on the top side of the photovoltaic module 2, two second hinged ears 62 are fixed on the top side of the waterproof plate 6, and the two first hinged ears 61 and the two second hinged ears 62 are rotationally connected through the rotating shaft 63, so that the waterproof plate 6 can rotate relative to the photovoltaic module 2. The rotating shaft 63 is sleeved with a torsional spring 64 at both ends, and one end of the torsional spring 64 is fixed on the rotating shaft 63 and the other end is fixed on the corresponding first hinged ear 61 or second hinged ear 62, so that the torsional spring 64 can rotate the bottom of the waterproof plate 6 to be buckled in the inner side of the horizontal groove beam 12.

[0060] When the photovoltaic module 2 is installed, the torsional spring 64 sleeved on the rotating shaft 63 of the hinged seat rotates the bottom of the waterproof plate 6 to be buckled in the inner side of the horizontal groove beam 12, so as to block the gap between the top of the bottom surface of the photovoltaic module 2 and the horizontal groove beam 12, and the water or sundries falling into the horizontal groove beam 12 is not easy to fall into the room through the gap between the top of the bottom surface of the photovoltaic module 2 and the horizontal groove beam 12. At the same time, the waterproof plate 6 covers the locking screw 43, which can protect the locking screw 43 and delay the rusting and damage of the locking screw 43.

[0061] Referring to Figure 6 Specifically, in the embodiment, the bottom of the waterproof plate 6 is in a coiled cylindrical shape. When the photovoltaic module 2 is turned over, the top of the photovoltaic module 2 drives the corresponding movement of the waterproof plate 6, so that the contact position of the bottom of the waterproof plate 6 with the inner side of the horizontal groove beam 12 moves. Since the bottom of the waterproof plate 6 is in a coiled cylindrical shape, the bottom of the waterproof plate 6 and the inner side of the horizontal groove beam 12 form a circular arc tangent state at this time, which can facilitate the relative movement between the waterproof plate 6 and the inner side of the horizontal groove beam 12.

[0062] The implementation principle is that: in the normal use process, the driving unit 3 drives the Z-shaped rotating shaft 24 to rotate forward, so that the Z-shaped rotating shaft 24 drives the photovoltaic module 2 to turn upward and open, so as to ventilate the room and the outside. Similarly, when it rains, the driving unit 3 drives the Z-shaped rotating shaft 24 to rotate reversely, so that the Z-shaped rotating shaft 24 drives the photovoltaic module 2 to turn downward and close, so that the external rainwater is not easy to enter the room.

[0063] In addition, when the surface of the photovoltaic module 2 is accumulated with sand, snow and other sundries, the driving motor 31 drives the driving sprocket 34 to rotate, and the driving sprocket 34 drives multiple transmission sprockets to rotate through the transmission chain 32, so as to control the Z-shaped rotating shaft 24 in the same column of photovoltaic modules 2 to rotate, and then control the photovoltaic module 2 to make continuous periodic swing, so as to shake off the sundries on the surface of the photovoltaic module 2 to the horizontal groove beam 12.

[0064] Meanwhile, when the driving motor 31 drives the photovoltaic module 2 to continuously and periodically swing through the transmission chain 32, the first transmission sprocket 33 and the Z-shaped rotating shaft 24, the driving motor 31 drives the material stirring roller 123 to rotate through the transmission chain 32 and the second transmission sprocket 125 at the same time, so that the spiral stirring blades 124 on the material stirring roller 123 push the sundries in the horizontal groove beam 12 into the longitudinal groove beam 11 along the length direction of the horizontal groove beam 12, and finally fall through the longitudinal groove beam 11, so that the sundries are not easily accumulated and blocked in the horizontal groove beam 12.
