DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-Figure 9 A roof structure for solar photovoltaic power generation, a roof structure for solar photovoltaic power generation, comprising a plurality of vertical beams 100, a plurality of vertical beams 100 are vertically mounted with a horizontal beam 110 through a mounting mechanism 200, a plurality of vertical beams 100 and a plurality of horizontal beams 110 are mounted with a mounting frame 300 through a plurality of first bolts 120, and a plurality of solar panels 310 are mounted on the mounting frame 300; A reinforcement mechanism 400 is provided on both the vertical beam 100 and the horizontal beam 110, and a support mechanism 500 is provided on the mounting frame 300. The support mechanism 500 is connected to the two reinforcement mechanisms 400 for reinforcement support. The reinforcement mechanism 400 includes a first straight support plate 410, two first L-shaped support plates 420, two second L-shaped support plates 430 and a second straight support plate 440 distributed in a rectangular shape; The two first L-shaped support plates 420 are slidably disposed on the first straight support plate 410, the two second L-shaped support plates 430 are slidably disposed on the two first L-shaped support plates 420, and the second straight support plate 440 is slidably disposed on the two second L-shaped support plates 430; The two reinforcement mechanisms 400 are axially symmetrically distributed along the diagonal formed by the vertical beam 100 and the horizontal beam 110; The reinforcement mechanism 400 further includes two adjustment components 450 symmetrically arranged on the first straight support plate 410 , and the adjustment components 450 are used to achieve the scaling of the rectangle formed by the reinforcement mechanism 400 to adapt to the vertical beam 100 and the horizontal beam 110 ; The support mechanism 500 includes two first support arms 510 and a second support arm 520 . The two first support arms 510 are respectively disposed on two first straight support plates 410 , and the second support arm 520 is disposed on the mounting frame 300 . The two first support arms 510 are slidably connected to the second support arms 520 .

[0032] In this embodiment: the vertical beam 100 can be a steel beam of the building roof itself, or it can be installed on the roof by bolts or welding. The cross beam 110 is detachably fixed to the vertical beam 100 through the mounting mechanism 200 to provide support, and the connection angle is 90°. The vertical beams 100 and the cross beams 110 are arranged in two rows, and the number of each row is equal. The V-shaped mounting frame 300 is then installed on multiple vertical beams 100 and multiple cross beams 110 by multiple first bolts 120. In order to improve the efficiency of photovoltaic power generation, solar panels 310 arranged in a grid are installed on both sides and the middle of the mounting frame 300.

[0033] A rectangular reinforcement mechanism 400 is mounted on both the vertical beam 100 and the horizontal beam 110 . The two reinforcement mechanisms 400 are connected by an inclined support mechanism 500 , thereby reinforcing and supporting the vertical beam 100 and the horizontal beam 110 .

[0034] Since the contact surface between the reinforcement mechanism 400 and the horizontal beam 110 or the vertical beam 100 surrounds the overall surface of the square rod shape, compared with the contact point between the reinforcing rib and the vertical beam 100 or the horizontal beam 110, the stress can be evenly transmitted to the entire surface of the vertical beam 100 or the horizontal beam 110.

[0035] Furthermore, the size of the reinforcement mechanism 400 is also adjustable, and can be adapted to vertical beams 100 or horizontal beams 110 of different models and sizes, which significantly improves the versatility. Correspondingly, the length of the support mechanism 500 is also adjustable.

[0036] Taking a group of reinforcement mechanisms 400 installed on the vertical beam 100 as an example, the reinforcement mechanism 400 installed on the vertical beam 100 includes a first straight support plate 410 attached to the middle of the front end of the vertical beam 100 and a second straight support plate 440 attached to the middle of the rear end of the vertical beam 100. Two first L-shaped support plates 420 are symmetrically slidably installed on the left and right ends of the first straight support plate 410, and two second L-shaped support plates 430 are symmetrically slidably installed on the rear ends of the two first L-shaped support plates 420. The two second L-shaped support plates 430 are symmetrically slidably installed on the left and right ends of the second straight support plate 440.

[0037] A scalable rectangular structure is formed by the first straight support plate 410, two first L-shaped support plates 420, two second L-shaped support plates 430 and the second straight support plate 440, so as to fit vertical beams 100 of different models and sizes, and the scaling of the rectangle is controlled by the adjustment component 450.

[0038] The reinforcing mechanism 400 installed on the cross beam 110 is similar, and the two reinforcing mechanisms 400 are also symmetrically distributed at an angle of 45° between the vertical beam 100 and the cross beam 110 .

[0039] Two first support arms 510 are also symmetrically fixed on the two first straight support plates 410 , and the two first support arms 510 are symmetrically slidably mounted on the second support arms 520 .

[0040] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 8 The mounting mechanism 200 includes a mounting plate 210 disposed on the vertical beam 100 . The mounting plate 210 is connected to the vertical beam 100 through a plurality of second bolts 220 . The horizontal beam 110 is connected to the mounting plate 210 through a plurality of third bolts 230 .

[0041] In this embodiment: the mounting plate 210 is in a tic-tac-toe shape, and corresponding threaded holes are provided on the mounting plate 210 and the vertical beam 100. The mounting plate 210 is fixed to the vertical beam 100 by a plurality of second bolts 220 symmetrically arranged on both sides, and the cross beam 110 is similarly fixed to the mounting plate 210 by a plurality of third bolts 230, thereby achieving the installation of the cross beam 110 on the vertical beam 100 and being detachable.

[0042] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 3-Figure 9 The first L-shaped support plate 420 includes a first support plate member 421 and a second support plate member 422. The first support plate member 421 is slidably disposed on the first straight support plate 410, and the second L-shaped support plate 430 is slidably disposed on the second support plate member 422. A first rotating drum 423 is rotatably disposed in the first supporting plate member 421 , and a connecting plate 424 is disposed on the second supporting plate member 422 , and the connecting plate 424 is disposed on the first rotating drum 423 ; The second straight support plate 440 includes a third support plate component 441 and a fourth support plate component 442, which are respectively slidably disposed on the two second L-shaped support plates 430, the fourth support plate component 442 is provided with a first magnetic block 443, and the third support plate component 441 is provided with a second magnetic block 444.

[0043] In this embodiment: if the rectangular structure of the reinforcement mechanism 400 itself can only be scaled but cannot be disassembled or the disassembly operation is relatively troublesome, the convenience of installation will be greatly reduced.

[0044] Therefore, the first L-shaped support plate 420 is composed of a first support plate member 421 and a second support plate member 422. The first support plate member 421 is slidably mounted on the first straight support plate 410, and the first rotating cylinder 423 is rotatably mounted on the upper and lower inner walls of the first support plate member 421. A connecting plate 424 is fixed on the first rotating cylinder 423, and the second support plate member 422 is fixed on the connecting plate 424. The second L-shaped support plate 430 is slidably mounted on the second support plate member 422.

[0045] The second straight support plate 440 is also composed of two symmetrical parts, the third support plate component 441 and the fourth support plate component 442. The first magnetic block 443 is fixed on the fourth support plate component 442, and the part of the third support plate component 441 close to the fourth support plate component 442 is the second magnetic block 444 with opposite magnetic properties to the first magnetic block 443.

[0046] Embodiment 4: This embodiment is an improvement on Embodiment 3. For details, please refer to Figure 3-Figure 9 , the adjustment assembly 450 includes a first connection rope 451, and the first connection rope 451 is slidably disposed on the first straight support plate 410 and the first L-shaped support plate 420; One end of the first connecting rope 451 is connected to the second straight support plate 440, and the first connecting rope 451 is wound around the first rotating drum 423, and the other ends of the two first connecting ropes 451 are movable and penetrate to the outside of the first straight support plate 410; The adjustment assembly 450 further includes a second drum 452 rotatably disposed in the second L-shaped support plate 430 , and the first connecting rope 451 is wound around the second drum 452 , and the winding direction of the first connecting rope 451 on the second drum 452 is opposite to the winding direction of the first connecting rope 451 on the first drum 423 ; The adjustment assembly 450 further includes a first torsion spring 453 and a second torsion spring 454. The two ends of the first torsion spring 453 are respectively connected to the inner wall of the first rotating cylinder 423 and the first support plate member 421. The two ends of the second torsion spring 454 are respectively connected to the second rotating cylinder 452 and the inner wall of the second L-shaped support plate 430. The elastic force of the first torsion spring 453 is smaller than the elastic force of the second torsion spring 454 .

[0047] In this embodiment, in order to achieve scaling and splicing of the rectangular structure of the reinforcement mechanism 400 and to facilitate installation, a process of splicing first and then scaling is implemented.

[0048] Therefore, the second rotating drum 452 is rotatably mounted on both second L-shaped support plates 430. Two first connecting ropes 451 are symmetrically arranged on both sides of the first straight support plate 410, and the first connecting rope 451 movably passes through the first straight support plate 410, the first support plate member 421, the second support plate member 422 and the second L-shaped support plate 430. The first connecting rope 451 is wound around the first rotating drum 423, and after passing the first rotating drum 423, it is wound around the second rotating drum 452 in the opposite direction, and is fixed to the third support plate member 441 or the fourth support plate member 442.

[0049] The first rotating cylinder 423 and the second rotating cylinder 452 are hollow, and a first torsion spring 453 is arranged in the first rotating cylinder 423, and a second torsion spring 454 is arranged in the second rotating cylinder 452, wherein two ends of the first torsion spring 453 are respectively fixed to the inner wall of the first support plate member 421 and the inner wall of the first rotating cylinder 423, and two ends of the second torsion spring 454 are respectively fixed to the inner wall of the second L-shaped support plate 430 and the inner wall of the second rotating cylinder 452.

[0050] And the elastic force of the first torsion spring 453 is set to be smaller than the second torsion spring 454, so that when the first connecting rope 451 is not pulled, the first L-shaped support plate 420 and the second L-shaped support plate 430 on both sides are open under the elastic force of the first torsion spring 453, and by pulling the first connecting rope 451 toward the outside of the first straight support plate 410, the first rotating drum 423 can be driven to rotate first, and then the first L-shaped support plate 420 and the second L-shaped support plate 430 on both sides can be driven to rotate inward, and at this time, the first magnetic block 443 will also be assembled with the second magnetic block 444 due to the magnetic attraction.

[0051] Then, the first connecting rope 451 is continuously pulled, and the first rotating drum 423 does not rotate because the rectangle is completed, while the second rotating drum 452 is pulled to rotate, thereby driving the two second L-shaped support plates 430 and the two first L-shaped support plates 420 to scale based on the first straight support plate 410 until they are aligned with the vertical beam 100 or the horizontal beam 110 and then stop; Embodiment 5: This embodiment is an improvement made on the basis of Embodiment 4. For details, please refer to Figure 3-Figure 9 , the support mechanism 500 further includes two second connection ropes 530, and the two second connection ropes 530 are respectively connected to the four first connection ropes 451; A rotating rod 540 is rotatably disposed in the second supporting arm 520, and two second connecting ropes 530 are wound around the rotating rod 540 in opposite directions; The support mechanism 500 also includes a mounting block 550 , which is connected to the vertical beam 100 via a fourth bolt 560 . A screw rod 570 is rotatably provided on the mounting block 550 . The rotating rod 540 is connected to the screw rod 570 . The second support arm 520 is threadedly connected to the screw rod 570 .

[0052] In this embodiment, after the two first connecting ropes 451 in one reinforcement mechanism 400 extend out of the first straight support plate 410, they are combined into one strand through the second connecting rope 530. A rotating rod 540 is rotatably mounted on the second support arm 520, and the two second connecting ropes 530 are wound around the rotating rod 540 in opposite directions. By rotating the rotating rod 540, the four first connecting ropes 451 can be pulled at the same time, so that the two reinforcement mechanisms 400 can be expanded and contracted at the same time.

[0053] A mounting block 550 is detachably mounted on the front end of the vertical beam 100 through a fourth bolt 560, and the inclined surface of the mounting block 550 is parallel to the second support arm 520. A screw rod 570 is rotatably mounted on the inclined surface of the mounting block 550, and the second support arm 520 is threadedly connected to the screw rod 570.

[0054] By rotating the rotating rod 540, the two reinforcement mechanisms 400 will be spliced ​​and scaled, and the screw rod 570 will also be driven to rotate, thereby driving the second support arm 520 to move toward the angle between the vertical beam 100 and the horizontal beam 110 to adapt to the scaling of the two reinforcement mechanisms 400, until the two reinforcement mechanisms 400 are in fit with the vertical beam 100 and the horizontal beam 110, and the installation is completed.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
