For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0055] Example 1:

[0056] like Figures 1-22 As shown, a photovoltaic roof includes a roof structure layer 5 and a photovoltaic power generation device 1.

[0057] A track 2 is laid on top of the roof structure layer 5. The photovoltaic power generation device 1 is equipped with a photovoltaic panel 11, a fixing frame 12, a moving part 13 and a fixing part 16. The photovoltaic panel 11 is connected to the upper side of the fixing frame 12.

[0058] The movable component 13 includes two first rollers 131 and two second rollers 132. The two first rollers 131 are respectively connected to the left and right sides of the rear of the fixed frame 12, and the two second rollers 132 are respectively connected to the left and right sides of the front of the fixed frame 12. The movable component 13 can make the photovoltaic power generation device 1 move along the track 2.

[0059] The fixing member 16 is an adjustable clamp. The fixing member 16 includes a first clamp 161 and a second clamp 162. By adjusting the opening and closing degree of the first clamp 161 and the second clamp 162 and clamping them on the track 2, the photovoltaic power generation device 1 can be fixed on the track 2.

[0060] In practical implementation, the roof structure layer 5 serves as the foundation for supporting the photovoltaic power generation device 1, and can be in the form of reinforced concrete cast-in-place slab, precast composite slab, etc. The track 2 is fixed above the roof structure layer 5 by anchor bolts or welding, forming a linear guide path. The rear of the mounting frame 12 of the photovoltaic power generation device 1 is engaged with the track 2 via two first rollers 131, and the front is engaged with the track 2 via two second rollers 132, achieving directional sliding along the track 2. The fixing component 16 adopts an adjustable gripper structure. The opening and closing action of the first gripper 161 and the second gripper 162 can be achieved through mechanical transmission. When the gripper is closed, it clamps the rail head 21 of the track 2, locking the photovoltaic power generation device 1 onto the track 2 by the combined action of friction and mechanical engagement.

[0061] The track 2 is fixed above the roof structure layer 5, forming a continuous rigid constraint; the adjustable claws (first claw 161, second claw 162) of the fastener 16 can form mechanical engagement and friction locking on the track 2, improving the wind overturning resistance of the photovoltaic power generation device 1.

[0062] The photovoltaic power generation device 1 can be quickly slid along the track 2 via the movable component 13 to the edge of the roof or to sheltered areas such as warehouses and sheds, allowing for rapid evacuation from exposed areas before severe weather such as hail. The detachable design of the track 2 and the fixing component 16 allows for quick dismantling and relocation of the device, preventing direct impact from falling hard objects on the photovoltaic panel 11.

[0063] Based on the above technical solutions, this utility model can be used to install solar photovoltaic panels on building roofs that are frequently exposed to extreme weather (such as typhoons, hail, etc.). It is easy to deploy and retract under extreme weather conditions, avoiding damage to the solar photovoltaic panels caused by extreme weather.

[0064] Example 2:

[0065] Furthermore, the fastener 16 also includes a gripper frame 163 and an adjusting bolt 164;

[0066] A claw hinge shaft 1633 is connected between the front wall and the rear wall of the gripper frame 163. The first claw 161 and the second claw 162 are hinged together by the claw hinge shaft 1633 and pass through the inner side of the gripper frame 163.

[0067] The top of the first claw 161 is rotatably connected to an adjusting shaft 1611, and the top of the second claw 162 is rotatably connected to an adjusting shaft 1621. Both the adjusting shaft 1611 and the adjusting shaft 1621 are provided with through holes. The through hole of the adjusting shaft 1611 is a threaded hole. The adjusting bolt 164 passes through the through hole of the adjusting shaft 1621 and is threadedly connected to the through hole of the adjusting shaft 1611. The bolt head of the adjusting bolt 164 abuts against the outside of the adjusting shaft 1621 so that the first claw 161 and the second claw 162 can be clamped or loosened on the track 2.

[0068] In practice, when the adjusting bolt 164 is rotated, the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621 changes because the adjusting bolt 164 is threadedly connected to the adjusting shaft 1611. When it is necessary for the first claw 161 and the second claw 162 to be clamped on the track 2, rotating the adjusting bolt 164 reduces the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621, thereby causing the first claw 161 and the second claw 162 to rotate around the claw hinge shaft 1633, thus achieving the clamping or loosening of the first claw 161 and the second claw 162 on the track 2. When it is necessary to loosen the first claw 161 and the second claw 162 on the track 2, rotating the adjusting bolt 164 increases the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621, and the first claw 161 and the second claw 162 will be released from the clamped state. The opening and closing of the first claw 161 and the second claw 162 can be controlled by adjusting the bolt 164, facilitating quick switching between fixing and moving the device on the track 2. The rotatable connection between the gripper frame 163 and the left plate 141 and right plate 143 allows the fixing component 16 to adapt to different positions and angles on the track 2, thereby improving the adaptability of the device. The clamping action of the first claw 161 and the second claw 162 can firmly fix the device on the track 2, preventing the device from moving during operation.

[0069] The front, rear, left, and right walls of the gripper frame 163 can be designed to be detachably connected by bolts, allowing each wall to be disassembled individually for easy replacement or maintenance of components such as the first gripper 161 and the second gripper 162 inside the gripper frame 163. The bolt head of the adjusting bolt 164 can directly abut against the outside of the adjusting shaft 1621, or it can abut against the outside of the adjusting shaft 1621 via a collar. More specifically, the adjusting bolt 164 includes a threaded section and a smooth section. The threaded section engages with the threaded hole of the adjusting shaft 1611 to achieve axial displacement adjustment, while the smooth section passes through the through hole of the adjusting shaft 1621. The through hole of the adjusting shaft 1621 can also be a threaded hole, allowing the adjusting bolt 164, including the threaded section and the smooth section, to also pass through the through hole of the adjusting shaft 1611 and be threadedly connected to the through hole of the adjusting shaft 1621, thereby increasing the applicability of the workpiece.

[0070] Example 3:

[0071] Furthermore, a foundation beam 51 is provided above the roof structure layer 5, and the track 2 is laid on the foundation beam 51.

[0072] In practice, a foundation beam 51 is installed above the roof structure layer 5, and the track 2 is fixed to the top surface of the foundation beam 51 with bolts. The foundation beam 51 can be a concrete beam or a steel beam, and they are arranged at intervals on the roof. The gaps between adjacent foundation beams 51 can be used to lay water pipes, air ducts, electrical conduits and other pipelines. The pipelines and the track 2 are arranged in layers to avoid cross-interference.

[0073] Example 4:

[0074] Furthermore, a truss 52 is provided above the roof structure layer 5, and the track 2 is laid on the truss 52.

[0075] In practice, the truss 52 can be formed by welding or bolting steel members to create a grid-like support system. As a result, the area below the photovoltaic power generation device 1 can be used as a multi-functional space such as a roof garden, sunroom, and leisure platform, making full use of the roof space structure.

[0076] Example 5:

[0077] Furthermore, the first roller 131 is connected to the fixed frame 12 via the bracket 14, and the second roller 132 is connected to the fixed frame 12 via the support rod assembly 15. The support rod assembly 15 includes a first support rod 151 and a second support rod 152. The upper part of the first support rod 151 is detachably connected to the fixed frame 12, and the lower part of the first support rod 151 is rotatably connected to one end of the wheel axle of the second roller 132. The upper part of the second support rod 152 is hinged to the fixed frame 12, and the lower part of the second support rod 152 is connected to the other end of the wheel axle of the second roller 132, so that when the photovoltaic power generation device 1 is in the upright state, an angle is formed between the photovoltaic panel 11 and the track 2.

[0078] In specific implementation, this utility model can achieve the photovoltaic power generation device 1 in a standing state and form an inclination angle by connecting the first support rod 151 and the second support rod 152 with the fixed frame 12. The design of this inclination angle can be adjusted in combination with the optimal inclination angle determined by factors such as the latitude and season of the local area, so as to ensure that the photovoltaic panel 11 can receive sunlight to the maximum extent and improve the power generation efficiency.

[0079] This invention can also achieve folding of the support rod assembly 15 by disconnecting the first support rod 151 from the fixing frame 12. When a folded state is required, by disconnecting the first support rod 151 from the fixing frame 12, and since the upper part of the second support rod 152 is hinged to the fixing frame 12 and can rotate, and the lower part of the first support rod 151 is rotatable from the axle of the second roller 132, the support rod assembly 15 can be rotated towards the fixing frame 12, causing the support rod assembly 15 to fold up (e.g., ...). Figure 10 As shown in the figure, this reduces the overall size of the device, making it easier to deploy and store the photovoltaic power generation device 1 in a shaded area during inclement weather.

[0080] More specifically, a folding fixing hole 1511 can be provided on the first support rod 151 for bolt connection with the corresponding reserved hole on the fixing frame 12 to maintain the folded state, thereby facilitating transportation and storage. If the folding fixing hole 1511 is not provided, the first support rod 151 can also be tied to the fixing frame 12 by cable ties or wire.

[0081] Example 6:

[0082] Furthermore, the upper end of the first support rod 151 is detachably connected to the angle adjustment hole 125 of the fixing frame 12, so that the photovoltaic power generation device 1 can fold the support rod assembly 15 by disconnecting the first support rod 151 from the angle adjustment hole 125, and adjust the angle of the support rod assembly 15 by adjusting the connection between the first support rod 151 and the angle adjustment hole 125.

[0083] In practical implementation, the angle adjustment hole 125 can be designed as a strip-shaped hole to achieve stepless adjustment of the tilt angle within a certain range (e.g., Figure 11 , Figure 12 (As shown). Multiple circular holes at different positions can also be set to achieve a specified angle adjustment. When angle adjustment is required, the connection of the angle adjustment hole 125 (strip hole) on the fixing frame 12 at different positions can be changed, or the connection of the first support rod 151 to the angle adjustment hole 125 (circular hole) at different positions can be changed. This can change the included angle between the first support rod 151 and the second support rod 152 and the fixing frame 12, thereby changing the tilt angle between the fixing frame 12 and the track 2, and realizing the adjustment of the tilt angle of the photovoltaic panel 11 to adapt to different lighting conditions.

[0084] Example 7:

[0085] Furthermore, the fixing member 16 is connected to the bracket 14 via the gripper frame 163. The bracket 14 includes a left plate 141, a connecting plate 142, and a right plate 143 connected in sequence. The left plate 141 and the right plate 143 are respectively connected to the two ends of the wheel axle of the moving member 13. The left wall of the gripper frame 163 is rotatably connected to the left plate 141 via the left rotating shaft 1631, and the right wall of the gripper frame 163 is rotatably connected to the right plate 143 via the right rotating shaft 1632.

[0086] In practice, the gripper frame 163 of the fixing member 16 is connected to the left plate 141 and the right plate 143 of the bracket 14 via the left rotating shaft 1631 and the right rotating shaft 1632, which allows the fixing member 16 to rotate around the axis, making it convenient to adjust the clamping angle of the fixing member 16.

[0087] Preferably, the left wall of the gripper frame 163 is provided with a left fixing inner hole 1636, and the left plate 141 is provided with a left fixing outer hole 1411; when the left fixing inner hole 1636 and the left fixing outer hole 1411 are connected by a connector, the gripper frame 163 cannot rotate relative to the left plate 141 via the left rotating shaft 1631, so as to realize the folding of the fixing member 16;

[0088] And / or, the right wall of the gripper frame 163 is provided with a right fixing inner hole 1637, and the right plate 143 is provided with a right fixing outer hole 1431; when the right fixing inner hole 1637 and the right fixing outer hole 1431 are connected by a connector, the gripper frame 163 cannot rotate relative to the right plate 143 by the right rotating shaft 1632, so as to realize the folding of the fixing member 16.

[0089] Preferably, the left plate 141 is provided with a left adjustment hole 1412. The adjustment bolt 164 can be adjusted by passing an adjustment tool through the left adjustment hole 1412 to change the opening and closing degree of the first claw 161 and the second claw 162.

[0090] And / or, the right plate 143 is provided with a right adjustment hole 1432, and the adjustment bolt 164 can be adjusted by passing an adjustment tool through the right adjustment hole 1432 to change the opening degree of the first claw 161 and the second claw 162.

[0091] Example 8:

[0092] Furthermore, the track 2 is an I-shaped track, and the track 2 includes a rail head 21, a rail web 22 and a rail bottom 23 connected from top to bottom. The clamping parts of the first claw 161 and the second claw 162 are used to clamp the rail head 21.

[0093] The clamping part of the first claw 161 includes claw segment 1612, claw segment 2 1613 and claw segment 3 1614 connected from top to bottom, and the clamping part of the second claw 162 includes claw segment 4 1622, claw segment 5 1623 and claw segment 6 1624 connected from top to bottom.

[0094] When the first claw 161 and the second claw 162 are clamped on the rail head 21, claw segment 1612 and claw segment 41622 abut against the upper oblique end of the rail head 21, claw segment 21613 and claw segment 51623 abut against the lower oblique end of the rail head 21, and claw segment 31614 and claw segment 61624 are located on the lower side of the rail head 21.

[0095] In practice, the first claw segment 1612, the second claw segment 1613, and the third claw segment 1614 of the first claw 161, together with the fourth claw segment 1622, the fifth claw segment 1623, and the sixth claw segment 1624 of the second claw 162, can form a ring-shaped fixation around the rail head 21, ensuring a stable clamping and preventing slippage, thus avoiding the equipment from falling off under vibration or storm conditions. Furthermore, the clamping process will not cause wear to the running surface of the rail 2 (i.e., the upper surface of the rail head 21), extending the service life of the rail 2.

[0096] Example 9:

[0097] Furthermore, the fastener 16 is detachably connected to the limiting member 165;

[0098] The front wall of the gripper frame 163 is provided with a front limiting hole 1634, and the rear wall of the gripper frame 163 is provided with a rear limiting hole 1635. The limiting member 165 can pass through the front limiting hole 1634 and exit through the rear limiting hole 1635. The portion of the limiting member 165 located inside the gripper frame 163 can form a stop on the first claw 161 and / or the second claw 162 to limit the maximum opening degree of the first claw 161 and the second claw 162.

[0099] In practical implementation, although the clamping or loosening of the first claw 161 and the second claw 162 on the track 2 can be achieved by rotating the adjusting bolt 164, there are still some application scenarios where it is necessary to keep the first claw 161 and the second claw 162 clamped on the track 2 without disengaging, but also to maintain a certain amount of room for movement. In this case, the role of the limiting member 165 becomes particularly important. By setting the limiting member 165, it can form a stop on the first claw 161 and / or the second claw 162 (e.g., Figure 18 As shown in the diagram, even if the adjusting bolt 164 is adjusted further, the first claw 161 and the second claw 162 cannot open further, ensuring both stability and flexibility of the device on the track 2. This prevents accidental dislodgement while allowing necessary fine-tuning. Simultaneously, by removing the limiting component 165, the first claw 161 and the second claw 162 can be fully opened again, facilitating coarse adjustment, disassembly, or replacement of the device. The limiting component 165 can be a bolt, pin, shaft pin, elastic pin, etc., and can be adjusted according to actual needs.

[0100] Existing technologies for gripper designs rarely address their application in fixing and fine-tuning equipment on tracks, thus seldom include designs that limit the maximum opening of the grippers using detachable limiting components. This invention, by adding a limiting component 165, effectively solves the problem of excessive opening of the grippers during use, improving the stability and reliability of the fixation.

[0101] Example 10:

[0102] Furthermore, there are at least two photovoltaic power generation devices 1, which are arranged at an angle to each other and the front ends of the two photovoltaic power generation devices 1 are connected by splicing parts 19.

[0103] In practical implementation, when it is necessary to connect two photovoltaic power generation devices 1, the two devices can be fixed together by splicing parts 19, so that the two devices form a more stable force-bearing system. There are various types of splicing parts 19, such as steel rope, steel plate, steel pipe, angle steel, etc.

[0104] Preferably, the photovoltaic power generation device 1 is connected to a lifting frame 17, and the lifting frame 17 is provided with lifting rings.

[0105] The hoisting frame 17 facilitates the hoisting of the photovoltaic power generation device 1. Furthermore, the hoisting frame 17 can also be used to connect two photovoltaic power generation devices 1 into one unit.

[0106] In summary, this utility model can make full use of the unused area on the roof for flexible arrangement of photovoltaic power generation devices.
