Description

Technical Field

[0001] The utility model belongs to the technical field of mounting brackets, and in particular relates to a roof mounting structure for a solar photovoltaic panel. Background Art

[0002] A solar photovoltaic panel is a device that converts sunlight radiation into electrical energy. It consists of many solar cell modules, which can be connected in series or in parallel to form a solar power generation system.

[0003] Solar photovoltaic panel roof mounting brackets are bracket systems used to install photovoltaic panels on the roof of a building. These brackets are usually made of high-strength aluminum alloy or stainless steel, and are lightweight, corrosion-resistant and easy to install;

[0004] There is one installation situation of photovoltaic panels, where there is a reserved installation position, in which case there is sufficient and reasonable installation space. There is another situation for later installation, in which case no suitable position is reserved. Therefore, in actual installation, the installation site is limited. At this time, although the bottom bracket can be fixed on the ground, the space for installing photovoltaic panels on the upper part is limited. At this time, it is necessary to extend the photovoltaic panel laying bracket outward according to the actual situation, so as to increase the photovoltaic panel laying area as much as possible while ensuring stable installation. The existing method requires extension by welding, drilling holes, and bolting, which is difficult to operate and inefficient. The flatness of the bracket may also be affected after extension.

[0005] In order to solve the above problems, a solar photovoltaic panel roof installation structure is proposed in the present application. Utility Model Content

[0017] The utility model can simultaneously drive the first screw and the second screw to rotate through a separate second gear, and then drive the side extension frames at both ends and the upper extension frame at the upper end to be simultaneously unfolded or retracted through the first internal thread block, the second extension rod and the support rod, which is convenient for the retraction and deployment of the side extension frames and the upper extension frame, and can also ensure the stability of the structure after adjustment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] See also Figure 1-5 As shown, the utility model is a solar photovoltaic panel roof mounting structure, including a support foot 1, a combined frame 2 is fixed on the support foot 1, a mounting frame 3 is laid on the combined frame 2, a slidable side extension frame 4 is provided on the side of the mounting frame 3, a slidable upper extension frame 5 is provided on the upper end of the combined frame 2, the side extension frame 4 and the upper extension frame 5 are flush with the mounting surface of the mounting frame 3, a rotatable first lead screw 6 and a second lead screw 7 are installed at the lower end of the combined frame 2, the first lead screw 6 drives the upper extension frame 5 to slide on the combined frame 2 through a thread, the second lead screw 7 drives the side extension frame 4 to slide on the mounting frame 3 through a spiral drive, and the first lead screw 6 and the second lead screw 7 are linked to each other, and a mounting seat 12 is fixedly provided at the bottom of the combined frame 2.

[0030] Among them, a first extension rod 8 is fixed on the upper extension frame 5, and a first slide rail 9 is provided between the first extension rod 8 and the combined frame 2. A cross plate 10 is fixed to the end of the first extension rod 8 away from the upper extension frame 5, and a first internal thread block 11 is fixed to the bottom of the cross plate 10. The first internal thread block 11 is threadedly connected to the first lead screw 6, and the first lead screw 6 is rotatably installed on the mounting seat 12. The upper extension frame 5 slides on the combined frame 2 through the spiral moving force of the first lead screw 6 and the first internal thread block 11. The structure driven by thread in this embodiment is simple and reliable. The upper extension frame 5, the first extension rod 8, the cross plate 10, and the first internal thread block 11 can also be set to a disassembly structure. When the extension space on one side of the upper extension frame 5 is limited, the upper extension frame 5 is dismantled at this time, and the retraction and release of the side extension frame 4 will not be affected.

[0031] Among them, a second extension rod 13 is fixed on the side extension frame 4, and a second slide rail 14 is arranged between the second extension rod 13 and the mounting frame 3. The side extension frame 4 is slidably connected to the combined frame 2 through the second extension rod 13 and the second slide rail 14. A support rod 16 is installed at the lower end of the side extension frame 4. The second lead screw 7 is spirally connected to the second internal thread block 15 on the outside, and a connecting rod 17 is hinged between the second internal thread block 15 and the support rod 16. The second lead screw 7 is rotatably installed on the mounting seat 12 and is located directly below the first lead screw 6. The side extension frame 4 slides on the side of the mounting frame 3 through the moving force of the second lead screw 7 and the second internal thread block 15 spirally. In this embodiment, the two connecting rods 17 are driven by the movement of a single second internal thread block 15 and the side extension frames 4 on both sides are driven to slide synchronously, which has a high degree of structural coordination. The side extension frame 4 and the connecting rod 17 can also be set as a detachable structure. When the mounting bracket is fixed, if the position of one side is limited and the mounting frame cannot be extended, the side extension frame 4 and the connecting rod 17 on that side can be removed without affecting the normal use of the side extension frame 4 and the upper extension frame 5 that have not been removed.

[0032] Among them, a first gear 18 is fixed to one end of the first lead screw 6, and a second gear 19 is fixed to the same end of the second lead screw 7. The first gear 18 and the second gear 19 are meshed with each other, and a hand wheel 20 is fixed to the other end of the second lead screw 7. In this embodiment, the first gear 18 and the second gear 19 are consistent in size, so that the number of rotations of the first lead screw 6 and the second lead screw 7 after the two are meshed is consistent. The size of the first gear 18 can also be smaller than the second gear 19, but at this time, the pitch of the first lead screw 6 and the second lead screw 7 is the same, which mainly drives the first internal thread block 11 and the second internal thread block 15 to move different distances, thereby ensuring the consistency of the deployment distance of the side extension frame 4 and the upper extension frame 5.

[0033] Among them, the pitch of the first screw 6 is smaller than the pitch formed on the second screw 7. In this embodiment, through the pitch difference between the first screw 6 and the second screw 7, the side extension frame 4 and the upper extension frame 5 connected in different ways can be unfolded to the same distance when the hand wheel 20 is rotated the same number of times, which facilitates operation while ensuring the consistency of unfolding.

[0034] It can be understood that firstly, the slidable side extension frame 4 and the upper extension frame 5 are provided, which can increase the upper space of the mounting frame without changing the installation range of the support leg 1, thereby increasing the installation space of the photovoltaic panel while ensuring stability; secondly, the retraction and extension of the two side extension frames 4 and the upper extension frame 5 are controlled by the second gear 19 and two linked lead screws with different pitches, which has the advantages of convenient operation and stable structure.

[0035] A specific application of this embodiment is: the bottom of the combined frame 2 is fixedly installed on the roof. Although the installation space of the support leg 1 is limited, after the combined frame 2 and the mounting frame 3 are supported to a certain height, exceeding the height of the roof obstacle, the side extension frame 4 and the upper extension frame 5 can be unfolded;

[0036] Deployment of the side extension frame 4 and the upper extension frame 5: the second screw 7 is rotated by the second gear 19, and then the first screw 6 is driven to rotate synchronously under the meshing of the connecting rod 17 at one end and the first gear 18. At this time, the first screw 6 and the second screw 7 rotate synchronously on the mounting seat 12, and the first internal thread block 11 slides with the first screw 6 in a spiral motion. After the first internal thread block 11 slides, it drives the cross plate 10, the first extension rod 8, and the upper extension frame 5 to slide upward. At this time, the first extension rod 8 slides on the side of the combined frame 2 through the first slide rail 9, and the second extension rod 13 slides with the second screw 7 in a spiral motion. After the second extension rod 13 slides, it drives the side extension frames 4 on both sides to be deployed at the same time through the support rod 16. At this time, after the side extension frame 4 and the upper extension frame 5 are deployed, a plane for neatly laying photovoltaic panels is formed.
