DETAILED DESCRIPTION

[0017] 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.

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] See also Figure 1-7 As shown in the figure, this embodiment provides a photovoltaic bracket that is easy to install, such as Figure 1-2 As shown, it includes two vertical support arms 1, and two upper and lower transverse supporting columns 2 are fixedly connected between the vertical support arms 1. A retracting and unfolding mechanism 4 is provided on one side of the transverse supporting column 2. A plurality of photovoltaic modules 3 are slidably connected between the transverse supporting columns 2 through the retracting and unfolding mechanism 4. When installing, lifting the retracting and unfolding mechanism 4 can drive the plurality of photovoltaic modules 3 to disperse and rotate synchronously. When storing, lowering the retracting and unfolding mechanism 4 can drive the plurality of photovoltaic modules 3 to be retracted to the center position.

[0020] Reference Figure 3-4As shown, the retractable and unfolding mechanism 4 includes a retractable and unfolding adjustment plate 42 slidably connected between the two vertical supporting arms 1, and a plurality of slide grooves 43 are provided on the retractable and unfolding adjustment plate 42. The plurality of slide grooves 43 are all arranged in an inclined state and move toward the center position of the retractable and unfolding adjustment plate 42 from bottom to top. A plurality of connecting transmission kits 44 are movably sleeved on the upper transverse supporting column 2, and the side of the connecting transmission kit 44 close to the retractable and unfolding adjustment plate 42 is slidably connected in the slide groove 43, and the photovoltaic component 3 is rotatably connected to the bottom of the connecting transmission kit 44. In the initial state, the connecting transmission kit 44 is at the top position of the slide groove 43. When the retractable and unfolding adjustment plate 42 is lifted, the connecting transmission kit 44 can slide to the bottom of the slide groove 43 and drive the photovoltaic component 3 to translate to both sides along the transverse supporting column 2.

[0021] Combination Figure 5 As shown, a protective cross plate 47 is provided on one side of the transverse bearing column 2 located below, and a plurality of directional racks 48 are fixedly connected to the protective cross plate 47. Specifically, the protective cross plate 47 is fixedly connected between the vertical supporting arms 1 on both sides, and the protective cross plate 47 is arranged in parallel with the transverse bearing column 2.

[0022] A plurality of rings 45 are slidably sleeved on the horizontal supporting column 2 located at the bottom, and the upper end of the ring 45 is rotatably connected to a rotating gear 46. The upper end of the rotating gear 46 is fixedly connected to the lower end of the photovoltaic component 3, and the rotating gear 46 is matched with the directional rack 48. When the ring 45 translates, the directional rack 48 can drive the rotating gear 46 to rotate, thereby driving the photovoltaic component 3 to rotate.

[0023] It can be understood that during installation, the user can lift the retractable and unfolding adjustment plate 42 in the retractable and unfolding mechanism 4 to make the connecting transmission kit 44 slide from the top of the slide slot 43 to the bottom position of the slide slot 43. During the sliding process of the connecting transmission kit 44, the connecting sliding kit will also translate on the horizontal bearing column 2 located above, thereby driving the photovoltaic components 3 to translate to both sides along the direction of the horizontal bearing column 2, thereby increasing the spacing between the photovoltaic components 3 and realizing the synchronous dispersion of multiple photovoltaic components 3; at the same time, during the dispersion of the photovoltaic components 3, the horizontal bearing column 2 located below will also be driven The ring 45 on the protective cross plate 47 is translated synchronously, thereby driving the rotating gear 46 on the ring 45 to translate on the directional rack 48 of the protective cross plate 47, so that the rotating gear 46 can rotate while translating, thereby driving the photovoltaic assembly 3 to rotate, so that multiple photovoltaic assemblies 3 can be rotated while being synchronously dispersed, and multiple photovoltaic assemblies 3 can be quickly deployed in a short time, thereby improving the installation efficiency of multiple photovoltaic assemblies 3; optionally, the size of the rotating gear 46 can be different, and the gear closer to the center position can be smaller, so that the photovoltaic assembly 3 can complete a larger angle of rotation within a short distance. In the practical use of the photovoltaic assembly 3, the user can also adjust the deflection angle of the photovoltaic assembly 3 by adjusting the position of the retracting and unfolding adjustment plate 42 in the retracting and unfolding mechanism 4, so that it can better receive light and improve the photovoltaic conversion efficiency. During storage, in contrast to the installation process, the user can lower the position of the retractable and unfoldable adjustment plate 42 in the retractable and unfoldable mechanism 4 so that multiple photovoltaic modules 3 can gather toward the center position. At the same time, the photovoltaic modules 3 rotate inward so that the photovoltaic modules 3 can be stacked on each other, which saves storage space while also protecting the surface of the photovoltaic modules 3.

[0024] Furthermore, the connecting transmission kit 44, the slide groove 43, the photovoltaic assembly 3, the collar 45, the rotating gear 46 and the directional rack 48 are arranged in a one-to-one correspondence.

[0025] Of course, the collection and expansion mechanism 4 can also be further specifically designed, as shown below:

[0026] Furthermore, at the same time, refer to Figure 4 As shown, the retractable and unfoldable mechanism 4 further includes a vertical sliding frame 41 fixedly connected to the vertical support arm 1 , the vertical sliding frame 41 is slidably connected to the retractable and unfoldable adjustment plate 42 , and the retractable and unfoldable adjustment plate 42 can slide up and down in the vertical sliding frame 41 .

[0027] Combination Figure 4 and Figure 6-7As shown, a driving carrier frame 49 is fixedly connected between the two vertical support arms 1, and a threaded transmission rod 410 is rotatably connected to the driving carrier frame 49 at the vertical center line position. The outer wall of the threaded transmission rod 410 is threadedly connected to a lifting and lowering adjustment sleeve 411 fixedly connected to the retraction and extension adjustment plate 42. When the threaded transmission rod 410 rotates, it can drive the retraction and extension adjustment plate 42 to be lifted or lowered.

[0028] It can be understood that in actual use, by rotating the threaded transmission rod 410, the lifting adjustment sleeve 411 can drive the retractable and extended adjustment plate 42 to move up and down on its outer wall. As the up and down positions of the retractable and extended adjustment plate 42 change, multiple connecting transmission kits 44 can be synchronously slid at different positions of the inner cavity of the slide groove 43, so that the distance between two corresponding connecting transmission kits 44 changes equidistantly, thereby changing the distance between the corresponding two photovoltaic components 3. Optionally, the threaded transmission rod 410 can be rotated manually without additional power, which is energy-saving and environmentally friendly, or it can be driven by a motor, which is convenient and fast, and this embodiment does not impose any specific restrictions.

[0029] It should be noted that, in order to further improve the photoelectric conversion efficiency of the photovoltaic module 3, a rotating adjustment base 5 can also be specifically designed, as shown in detail below:

[0030] More preferably, referring to Figure 6 and Figure 2-3 As shown, it also includes a rotation adjustment base 5, which includes a supporting bottom plate 51, and first support seats 52 are fixedly connected to both sides of the top surface of the supporting bottom plate 51. A rotation connecting rod 53 is rotatably connected between the first support seats 52, and an auxiliary support plate 54 is fixedly connected to the rotation connecting rod 53.

[0031] Specifically, the auxiliary support plate 54 can play an auxiliary supporting role for the vertical support arm 1, making the entire structure more stable.

[0032] The top surface of the supporting base plate 51 is also fixedly connected to a second support seat 55 on both sides, and an electric telescopic rod 56 is rotatably connected inside the second support seat 55. The other end of the electric telescopic rod 56 is rotatably connected to a limit linkage rod 57 fixedly connected to the vertical support arm 1, and the limit linkage rod 57 is fixedly connected to the rotating connecting rod 53.

[0033] It is understandable that when it is necessary to adjust the illumination angle of the photovoltaic assembly 3, the electric telescopic rod 56 can be driven to extend it, and then the limit linkage rod 57 can be pushed to drive the rotating connecting rod 53 to rotate inside the first support seat 52, so that the auxiliary support plate 54 combined with the limit linkage rod 57 drives the vertical support arm 1, the horizontal load-bearing column 2 and multiple photovoltaic assemblies 3 as a whole to deflect around the center of the rotating connecting rod 53 until the surface of the photovoltaic assembly 3 is facing direct sunlight, thereby increasing the light receiving time of the photovoltaic assembly 3 and capturing more sunlight energy, thereby improving the power generation efficiency of the photovoltaic assembly 3; at the same time, when storage is needed, the user can continue to drive the electric telescopic rod 56 to extend it further until the vertical support arm 1 rotates to a position parallel to the supporting base plate 51, so as to minimize the space occupied by the entire structure and make it easier to store and transport.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
