Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, specifically relating to a stable bracket for photovoltaic power generation modules. Background Technology

[0002] A photovoltaic (PV) module support is a supporting device used in a solar photovoltaic (PV) power generation system to place, install, and fix PV modules. Its main function is to ensure that the solar panels can operate stably under various environmental conditions and to maximize the absorption of solar radiation. PV module supports need to be customized according to the size and shape of the solar panels to meet the installation requirements in different environments.

[0003] Patent application CN202320455538.6 discloses a ground-mounted photovoltaic (PV) module support bracket. By setting an abutment plate and supporting components, during PV module installation, the main body of the bracket is first installed on the ground, then the bottom surface of the PV module is bolted to the supporting components, and finally the abutment plate is tightened onto the supporting components with bolts, so that the bottom surface of the abutment plate abuts against the top surface of the PV module. The PV module is sandwiched between the supporting components and the abutment plate, and is not easily detached from the supporting components due to the pressure and friction of the abutment plate. However, the bracket component disclosed in this utility model has a fixed orientation and cannot change the orientation of the solar PV panel, resulting in low power generation efficiency. Existing technologies also disclose some solutions for adjusting the orientation of solar PV panels, but most of them can only adjust the angle in a single orientation.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a stable support for photovoltaic power generation modules, so as to solve the problem that the orientation of the support modules is fixed and it is inconvenient to adjust the orientation of the solar photovoltaic panels.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A robust support structure for photovoltaic power generation modules, comprising:

[0008] The base has a mounting plate in the middle and fixing plates at both ends; the fixing plates have limiting components on both sides above.

[0009] The first sliding assembly, located above the base, includes a drive motor and two symmetrically arranged sliding frames. An arc-shaped guide groove is provided on the top of each sliding frame, and the bottoms of the two sliding frames are connected by a connecting plate. An L-shaped limiting plate, which mates with the corresponding limiting member, is rotatably connected to the outer side of each sliding frame. The drive motor is fixed to the mounting plate, and its output shaft is connected to a transmission screw. The transmission screw is threaded into the connecting plate, and its end away from the drive motor is rotatably connected to the fixed plate.

[0010] The second sliding component has the same structure as the first sliding component and is symmetrically arranged on the base with the first sliding component.

[0011] A solar photovoltaic panel is located above the base, and its outer frame has guide posts at both ends that slide in conjunction with the guide groove; one end of the guide post passes through the guide groove and is rotatably connected to the top of the limiting plate.

[0012] Preferably, the limiting component includes a limiting frame and a second limiting plate; the limiting frame is welded and fixed to the upper sides of the fixed plate, with an opening on the side facing the drive motor; the limiting frame is provided with a compression spring inside, and two symmetrical sliding grooves are provided at its top and bottom; the front end of the second limiting plate extends out of the limiting frame and cooperates with the first limiting plate, and its rear end abuts against the compression spring; the top and bottom of the second limiting plate are provided with sliders, and the two sliders are respectively located in the corresponding sliding grooves.

[0013] Preferably, the limiting plate includes a first plate and a second plate arranged vertically; one end of the first plate is rotatably connected to the guide post, and the end of the second plate away from the first plate cooperates with the limiting plate.

[0014] Preferably, the base is provided with slide rails on both sides; the bottom of the sliding frame is provided with pulleys, which are located inside the slide rails.

[0015] Preferably, the upper half of the sliding frame has a fan-shaped hollow groove one, and the lower half has a square hollow groove two; the middle part of the fixing plate has a square hollow groove three.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The sturdy photovoltaic power generation module bracket of this utility model, by setting a symmetrical first sliding component and a second sliding component on the base, allows the guide column on the outer frame of the solar photovoltaic panel to slide along the arc-shaped guide groove under the drive of the drive motor, which can change the orientation of the solar photovoltaic panel and improve the power generation efficiency.

[0018] (2) The sturdy photovoltaic power generation module support of this utility model has pulleys at the bottom of the sliding frame, which can move along the slide rail on the base, thereby reducing the friction between the sliding frame and the base when moving.

[0019] (3) The sturdy photovoltaic power generation module bracket of this utility model has a limiting component on the base. When the sliding frame moves to contact the fixed plate, the limiting component cooperates with the limiting plate on the side of the sliding frame to prevent the two sliding components from affecting each other when sliding.

[0029] See attached document Figure 1-3 A robust support structure for photovoltaic power generation modules, comprising:

[0030] The base 1 has a mounting plate 2 in the middle and fixing plates 3 on both ends above it; the fixing plates 3 have limiting parts 4 on both sides above them.

[0031] The first sliding assembly 5, located above the base 1, includes a drive motor 6 and two symmetrically arranged sliding frames 7; the top of the sliding frame 7 is provided with an arc-shaped guide groove 8, and the bottoms of the two sliding frames 7 are connected by a connecting plate 9; the outer side of the sliding frame 7 is rotatably connected to an L-shaped limiting plate 10 that cooperates with the limiting member 4 at the corresponding position; the drive motor 6 is fixed on the mounting plate 2, and its output shaft is connected to a transmission screw 11; the transmission screw 11 is threadedly engaged with the connecting plate 9, and its end away from the drive motor 6 is rotatably connected to the fixed plate 3;

[0032] The second sliding component 12 has the same structure as the first sliding component 5 and is symmetrically arranged on the base 1 with the first sliding component 5; when different sliding components are switched to move, the orientation of the solar photovoltaic panel 13 can be changed.

[0033] The solar photovoltaic panel 13 is located above the base 1, and its outer frame has guide posts 14 at both ends that slide in cooperation with the guide groove 8. When the guide posts 14 slide along the guide groove 8, the tilt angle of the solar photovoltaic panel 13 can be changed. One end of the guide post 14 passes through the guide groove 8 and is rotatably connected to the top of the limiting plate 10, which can drive the limiting plate 10 to rotate.

[0034] In this embodiment, the limiting component 4 includes a limiting frame 15 and a second limiting plate 16. The limiting frame 15 is welded and fixed to the upper sides of the fixing plate 3, with an opening on the side facing the drive motor 6. A compression spring 17 is provided inside the limiting frame 15, and two symmetrical sliding grooves 18 are provided at its top and bottom. The front end of the second limiting plate 16 extends out of the limiting frame 15 and cooperates with the first limiting plate 10, while its rear end abuts against the compression spring 17. Slider 19s are provided at the top and bottom of the second limiting plate 16, and the two sliders 19 are respectively located in the corresponding sliding grooves 18. The first limiting plate 10 includes a first plate and a second plate arranged vertically. One end of the first plate is rotatably connected to the guide post 14, and the end of the second plate away from the first plate cooperates with the second limiting plate 16.

[0035] It should be noted that when the drive motor 6 drives the sliding frame 7 to move toward the fixed seat, the guide column 14 on the solar photovoltaic panel 13 slides along the guide groove 8; since the first plate of the limiting plate 10 is rotatably connected to the guide column 14, the guide column 14 will drive the limiting plate 10 to rotate when it slides, so that the second plate of the limiting plate 10 rotates synchronously and slowly approaches the limiting plate 2 16.

[0036] See attached document Figure 3 Taking the first sliding assembly 5 as an example, when the drive motor 6 is started, the transmission screw 11 rotates, driving the connecting plate 9 and the two sliding frames 7 to move towards the fixed plate 3. When the first sliding assembly 5 moves close to the fixed plate 3, the second plate of the first limiting plate 10 will contact the second limiting plate 16, compressing the second limiting plate 16 and compressing the compression spring 17. During the contact between the second plate of the first limiting plate 10 and the second limiting plate 16, the slider 19 on the second limiting plate 16 will slide a short distance in the corresponding groove 18 until the second plate of the first limiting plate 10 rotates to a horizontal state. The second limiting plate 16 then rebounds back to its initial position under the elastic force of the compression spring 17. At this time, the sliding frame 7 contacts the fixed seat, the drive motor 6 stops working, the two sliding frames 7 will no longer move, and the second plate of the first limiting plate 10 will be limited by the second limiting plate 16. (See attached diagram.) Figure 1 When it is necessary to adjust the orientation of the solar photovoltaic panel 13 so that it faces the second sliding component 12, the drive motor 6 inside the second sliding component 12 can be activated to move the second component toward the first component. Since the second plate of the limiting plate 10 of the first component is limited by the corresponding limiting member 4, when the drive motor 6 inside the second sliding component 12 starts working, the sliding frame 7 of the first sliding component 5 will not move, thus maintaining the stability of the support structure.

[0037] On the other hand, in order to reduce the frictional resistance between the sliding frame 7 and the base 1 when moving, the base 1 is provided with slide rails 20 on both sides, and the bottom of the sliding frame 7 is provided with pulleys 21. The pulleys 21 are located inside the slide rails 20 and can move along the slide rails 20. The upper half of the sliding frame 7 has a fan-shaped hollow groove 22, and the lower half has a square hollow groove 23; the middle of the fixing plate 3 has a square hollow groove 24. The multiple hollow grooves can reduce the stress area when the wind blows, which is conducive to enhancing the overall wind resistance of the support structure and maintaining structural stability in windy weather.

[0038] This utility model provides a stable support for photovoltaic power generation modules. By setting symmetrical first sliding components 5 and second sliding components 12 on the base 1, and with the alternating operation of two drive motors 6, the guide column 14 on the solar photovoltaic panel 13 slides along the arc-shaped guide groove 8. This can adjust the tilt angle of the solar photovoltaic panel 13 and change its orientation, which is beneficial to improving power generation efficiency. It is very practical and has good market application prospects.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
