[0041] The present invention provides a rooftop solar power generation device, which includes an I-shaped chassis 1, two horizontal guide rails 2, two vertical guide rails 3, two horizontal sliding seats 4, two vertical sliding seats 5, a mounting frame 6, a plurality of photovoltaic panels 7, two horizontal racks 8, two horizontal drive mechanisms 9, two vertical racks 10, and two vertical drive mechanisms 11; the rooftop solar power generation device also includes a plurality of fixed teeth 12 and two locking mechanisms 13; the locking mechanism 13 includes a mounting block structure 131, a plurality of locking teeth 132, and a lifting structure 133; the mounting block structure 131 includes a mounting box 1311, a slider 1312, and two springs 1313; the lifting structure 133 includes A threaded barrel 1331, a drive motor 1332 and a screw 1333; the horizontal drive mechanism 9 includes a horizontal motor 91 and a horizontal gear 92; the vertical drive mechanism 11 includes a vertical motor 111 and a vertical gear 112; the fixed tooth 12 has two first inclined surfaces 121; the locking tooth 132 has two second inclined surfaces 1321; the fixed tooth 12 has a first rounded corner 122; the locking tooth 132 has a second rounded corner 1322; the rooftop solar power generation device also includes two reinforcing rods 14; through the above-mentioned scheme, when encountering strong winds, the photovoltaic panel 7 can be adjusted to a flat state to reduce the windward area, thereby reducing the impact of wind pressure and wind lift.

[0042] Furthermore, the two horizontal guide rails 2 are respectively fixedly arranged on the I-shaped chassis 1; the two vertical guide rails 3 are respectively fixedly arranged on the I-shaped chassis 1; a horizontal sliding seat 4 is slidably arranged on each of the horizontal guide rails 2; a vertical sliding seat 5 is slidably arranged on each of the vertical guide rails 3; one end of the mounting frame 6 is rotatably arranged between the two horizontal sliding seats 4, and the other end of the mounting frame 6 is rotatably arranged between the two vertical sliding seats 5; a plurality of photovoltaic panels 7 are fixedly arranged on the mounting frame 6;

[0043] A horizontal rack 8 is fixedly provided at the bottom of each horizontal guide rail 2; a horizontal driving mechanism 9 is provided on each horizontal sliding seat 4 for driving the horizontal sliding seat 4 to slide along the horizontal guide rail 2 through interaction with the horizontal rack 8;

[0044] A vertical rack 10 is fixedly provided on the side of each vertical guide rail 3 ; a vertical driving mechanism 11 is provided on each vertical sliding seat 5 for driving the vertical sliding seat 5 to slide along the vertical guide rail 3 through interaction with the vertical rack 10 .

[0045] In this embodiment, the I-type chassis 1 is used to fix the two horizontal guide rails 2 and the two vertical guide rails 3; the horizontal guide rails 2 and the vertical guide rails 3 on the same side are perpendicular to each other; the mounting frame 6 is used to fix and install multiple photovoltaic panels 7; the horizontal sliding seat 4 can slide along the horizontal guide rail 2 under the interaction of the horizontal driving mechanism 9 and the horizontal rack 8; similarly, the vertical sliding seat 5 can slide along the vertical guide rail 3 under the interaction of the vertical driving mechanism 11 and the vertical rack 10; therefore, in normal use, only the two vertical driving mechanisms 11 are started, and the two vertical sliding seats 5 slide along the two vertical guide rails 3. Driven by the mounting frame 6, the two horizontal sliding seats 4 will slide along the two horizontal guide rails 2, and the mounting When one end of the mounting frame 6 rotatably connected to the vertical sliding seat 5 is adjusted to be higher than the end rotatably connected to the horizontal sliding seat 4, the mounting frame 6 will be in an inclined state, and the inclination angle can be adjusted according to actual needs, so that the photovoltaic panel 7 can better receive sunlight; when encountering strong winds, only the two horizontal driving mechanisms 9 are started, and the two horizontal sliding seats 4 slide along the two horizontal guide rails 2. Driven by the mounting frame 6, the two vertical sliding seats 5 are lowered along the two vertical guide rails 3, and the mounting frame 6 will gradually be flattened until the two vertical sliding seats 5 drop to the lowest point. At this time, the mounting frame 6 is completely flat, and the multiple photovoltaic panels 7 are also flat; therefore, when encountering strong winds, the photovoltaic panels 7 can be adjusted to a flat state to reduce the windward area, thereby reducing the influence of wind pressure and wind lift force.

[0046] Furthermore, the rooftop solar power generation device further includes a plurality of fixing teeth 12 and two locking mechanisms 13;

[0047] A plurality of fixed teeth 12 are fixedly provided on the top of each horizontal guide rail 2; a locking mechanism 13 is provided on each horizontal sliding seat 4;

[0048] The locking mechanism 13 includes a mounting block structure 131 , a plurality of locking teeth 132 and a lifting structure 133 ;

[0049] The mounting block structure 131 is slidably arranged in the horizontal sliding seat 4; the multiple locking teeth 132 are respectively fixedly arranged at the bottom of the mounting block structure 131; the lifting structure 133 is arranged on the horizontal sliding seat 4, and is used to drive the mounting block structure 131 to rise and fall.

[0050] In this embodiment, the tooth pitch of two adjacent fixed teeth 12 is consistent with the tooth thickness of the locking teeth 132, and the tooth pitch of two adjacent locking teeth 132 is consistent with the tooth thickness of the fixed teeth 12, so that multiple locking teeth 132 can engage with multiple fixed teeth 12; after the horizontal sliding seat 4 is adjusted to a position on the horizontal guide rail 2, the lifting structure 133 drives the mounting block structure 131 to move downward, and the mounting block structure 131 drives the multiple locking teeth 132 to move downward, engage with the multiple fixed teeth 12, and lock the horizontal sliding seat 4.

[0051] Furthermore, the mounting block structure 131 includes a mounting box 1311 , a slider 1312 and two springs 1313 ;

[0052] The installation box 1311 is slidably set in the horizontal sliding seat 4; the slider 1312 is slidably set in the installation box 1311, and the multiple locking teeth 132 are respectively fixedly set at the bottom of the slider 1312; the two springs 1313 are respectively set in the installation box 1311 and located on both sides of the slider 1312.

[0053] In this embodiment, the installation box 1311 is used to slide and install the slider 1312, and the bottom of the slider 1312 is used to install multiple locking teeth 132. The slider 1312 has a certain sliding space in the installation box 1311 (there are movable gaps on the left and right sides), so the multiple locking teeth 132 also have a certain horizontal adjustment space; the two springs 1313 have the same specifications and are both in a certain compression state, constraining the slider 1312 to the center position; when the horizontal sliding seat 4 slides to a certain position and needs to be locked, but at this time the multiple locking teeth 132 are not aligned with the gaps between the multiple fixed teeth 12, but are opposite to the multiple fixed teeth 12, at this time the lifting structure 133 drives the installation box 1311 to move downward, and when driving the multiple locking teeth 132 to move downward, the multiple locking teeth 132 first contact with the multiple fixed teeth 12, Since the multiple locking teeth 132 are installed on the slider 1312 and can be moved and have a certain horizontal adjustment space, under the continuous drive of the lifting structure 133, the locking teeth 132 are gradually staggered with the fixed teeth 12. At this time, the multiple locking teeth 132 are inserted into the gaps between the multiple fixed teeth 12 to achieve complete engagement. At this time, the slider 1312 is also closer to the side of the installation box 1311, and the spring 1313 on this side is further compressed; although this will cause the horizontal sliding seat 4 to not be completely locked, but locked within a certain distance, and can rock within a certain distance, but this rocking distance is quite small and within a controllable range, and does not affect the overall stability; when the multiple locking teeth 132 move up and disengage from the gaps between the multiple fixed teeth 12, the two springs 1313 will adjust the slider 1312 to the center position. Figure 7 What is shown is the situation where the plurality of locking teeth 132 are just aligned with the gaps between the plurality of fixing teeth 12 and then inserted, and at this time the slider 1312 is still in the center position.

[0054] Furthermore, the lifting structure 133 includes a threaded barrel 1331 , a driving motor 1332 and a screw 1333 ;

[0055] The threaded barrel 1331 is fixedly arranged on the top of the mounting box 1311, and is slidingly connected to the horizontal sliding seat 4 and passes through the horizontal sliding seat 4; the driving motor 1332 is fixedly arranged on the top of the horizontal sliding seat 4; the screw 1333 is threadedly connected to the threaded barrel 1331 and is located inside the threaded barrel 1331, and the top end of the screw 1333 is fixedly connected to the output end of the driving motor 1332.

[0056] In this embodiment, the driving motor 1332 drives the screw 1333 to rotate, the screw 1333 drives the threaded barrel 1331 to move up and down, and the threaded barrel 1331 drives the installation box 1311 to move up and down.

[0057] Furthermore, the horizontal driving mechanism 9 includes a horizontal motor 91 and a horizontal gear 92;

[0058] The horizontal motor 91 is fixedly arranged on one side of the horizontal sliding seat 4 ; the horizontal gear 92 is fixedly arranged at the output end of the horizontal motor 91 and meshes with the horizontal rack 8 .

[0059] In this embodiment, the horizontal motor 91 drives the horizontal gear 92 to rotate, and the horizontal gear 92 meshes and rolls along the horizontal rack 8 , thereby driving the horizontal sliding seat 4 to slide along the horizontal guide rail 2 .

[0060] Furthermore, the vertical driving mechanism 11 includes a vertical motor 111 and a vertical gear 112;

[0061] The vertical motor 111 is fixedly arranged on one side of the vertical sliding seat 5 ; the vertical gear 112 is fixedly arranged at the output end of the vertical motor 111 and meshes with the vertical rack 10 .

[0062] In this embodiment, the vertical motor 111 drives the vertical gear 112 to rotate, and the vertical gear 112 meshes and rolls along the vertical rack 10 , thereby driving the vertical sliding seat 5 to slide along the vertical guide rail 3 .

[0063] Furthermore, the fixing tooth 12 has two first inclined surfaces 121 ; the locking tooth 132 has two second inclined surfaces 1321 .

[0064] In this embodiment, when the fixing tooth 12 is in relative contact with the locking tooth 132 , the first inclined surface 121 and the second inclined surface 1321 are in contact, and preferably staggered.

[0065] Furthermore, the fixing tooth 12 has a first rounded corner 122 ; the locking tooth 132 has a second rounded corner 1322 .

[0066] In this embodiment, when the fixing teeth 12 and the locking teeth 132 are completely opposite to each other, the first rounded corners 122 and the second rounded corners 1322 are in contact, and preferably staggered.

[0067] Furthermore, the rooftop solar power generation device further includes two reinforcing rods 14;

[0068] The two reinforcing rods 14 are respectively fixedly connected to the I-shaped chassis 1 and respectively fixedly connected to the two vertical guide rails 3 , and are respectively located on one side of the two vertical guide rails 3 .

[0069] In this embodiment, the reinforcing rod 14 , the I-shaped chassis 1 and the vertical guide rail 3 form a triangular structure, which is more stable.

[0070] The rooftop solar power generation device described in this embodiment, during normal use, only the two vertical drive mechanisms 11 are started, the two vertical sliding seats 5 slide along the two vertical guide rails 3, and driven by the mounting frame 6, the two horizontal sliding seats 4 slide along the two horizontal guide rails 2, and the end of the mounting frame 6 that is rotatably connected to the vertical sliding seat 5 is adjusted to be higher than the end that is rotatably connected to the horizontal sliding seat 4, and the mounting frame 6 is tilted, and the inclination angle can be adjusted according to actual needs, so that the photovoltaic panel 7 can better receive the solar radiation. Sunlight; when encountering strong winds, only the two horizontal drive mechanisms 9 are started, and the two horizontal sliding seats 4 slide along the two horizontal guide rails 2. Driven by the mounting frame 6, the two vertical sliding seats 5 descend along the two vertical guide rails 3, and the mounting frame 6 will gradually be flattened until the two vertical sliding seats 5 descend to the lowest point. At this time, the mounting frame 6 is completely flat, and the multiple photovoltaic panels 7 are also flat; therefore, when encountering strong winds, the photovoltaic panels 7 can be adjusted to a flat state to reduce the windward area, thereby reducing the impact of wind pressure and wind lift.
