Solar cell panel for photovoltaic power generation system

Abstract

The invention belongs to the technical field of photovoltaic power generation, and relates to a solar cell panel for a photovoltaic power generation system, which comprises a base, a mounting seat and a solar cell panel, and is characterized in that the base is provided with storable rollers and a linkage mechanism. The mounting base is connected with the sliding block of the second T-shaped sliding groove through the supporting rod of the first T-shaped sliding groove, and the sliding block is in linkage with the toothed plate-gear mechanism to control the abutting plate to move. When the angle is adjusted, the sliding block moves to drive the toothed plate to drive the gear, the abutting plate is made to give way, and the spring pushes the roller to retract to achieve fixation. And the roller extends out and turns into a moving state during reverse operation. The invention has the following three beneficial effects: 1) angle adjustment and state switching are synchronously completed, and the operation is convenient; 2) the base is directly grounded in a fixed state to enhance the stability; and 3) the rollers completely extend out in a moving state and are convenient to carry. The mechanical linkage structure realizes a one-adjustment double-control function, and the practicability and the working efficiency of the photovoltaic system are effectively improved.

Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and relates to a solar panel for a photovoltaic power generation system. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels, controllers, and inverters, and the main components are composed of electronic components. Solar cells can be connected in series and then encapsulated and protected to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device.

[0003] Currently, solar panel systems generally adopt a fixed installation method and are usually permanently installed on building roofs or ground brackets. This traditional installation mode has obvious limitations: on the one hand, since the panels are rigidly connected to the support structure, their positions and orientations are completely fixed and cannot be adjusted in real time according to the change of the solar azimuth angle, seriously affecting the photoelectric conversion efficiency; on the other hand, when the installation position needs to be changed, the entire support structure must be disassembled and reinstalled, which is not only time-consuming and laborious but may also damage the building roof. Although there are movable solar panel designs on the market, these solutions often have difficulty balancing mobility and working stability - when the panels are in a movable state, their wind resistance and seismic performance are significantly reduced, posing safety hazards under harsh weather conditions; and when the fixing measures are strengthened, the due mobility flexibility is lost. This contradiction between mobility and stability severely restricts the application scenarios and usage efficiency of solar energy devices.

[0004] To solve the above problems, the present invention proposes a solar panel for a photovoltaic power generation system. Summary of the Invention

[0010] The present invention is further configured such that through grooves are provided on both sides of the upper end surface of the second T-shaped sliding block, and shift blocks are slidably provided inside the through grooves, and the shift blocks are fixedly connected to the corresponding limit rods.

[0011] The present invention is further configured such that a groove is provided on the upper end surface of the second T-shaped sliding block, and the bottom end of the supporting rod is plug-fitted into the groove.

Detailed implementation manner

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 - 3 shown, the technical solution adopted by the present invention is as follows: A solar panel for a photovoltaic power generation system includes a base 1, a mounting seat 2 is rotatably installed on the base 1, and a solar panel 3 is limit installed on the upper end surface of the mounting seat 2. Specifically, a battery panel groove 27 is opened on the upper end surface of the mounting seat 2, rectangular grooves 28 are opened on both sides of the battery panel groove 27, positioning plates 29 are slidably arranged inside the rectangular grooves 28, a plurality of third springs 30 are fixedly connected inside the rectangular grooves 28, the other ends of the third springs 30 are fixedly connected to the positioning plates 29, and the side of the positioning plate 29 facing away from the third spring 30 is provided with an inclined surface. The inclined surface is provided to facilitate the installation of the solar panel 3 into the battery panel groove 27. The rapid installation and stable fixation of the solar panel 3 are realized, and the solar panel 3 is prevented from being displaced under the action of wind force.

[0027] When installing the solar panel 3, press the solar panel 3 into the battery panel groove 27. During the pressing process, the solar panel 3 is in sliding fit with the inclined surface of the positioning plate 29, so that the positioning plate 29 enters the inside of the rectangular groove 28, causing the third spring 30 to contract. When the solar panel 3 moves to the bottom end inside the battery panel groove 27, the solar panel 3 no longer blocks the positioning plate 29, so that the third spring 30 returns to its original state and drives the positioning plate 29 to extend out of the battery panel groove 27, thereby playing a limiting effect on the solar panel 3. The operation is simple.

[0028] As Figure 5 And Figure 7As shown, a plurality of mounting grooves 4 are formed on the lower end surface of the base 1, and rollers 5 are installed in the mounting grooves 4 in a limited sliding manner. Specifically, limiting sliding grooves 24 are formed on both sides inside the mounting groove 4, and moving blocks 25 are slidably installed inside the limiting sliding grooves 24. The moving blocks 25 are fixedly connected to the rollers 5. A second spring 26 is fixedly connected to the bottom side of the limiting sliding groove 24, and the other end of the second spring 26 is fixedly connected to the lower end surface of the moving block 25. The rollers 5 can be elastically telescoped, which not only ensures the flexibility during movement but also provides conditions for subsequent fixation.

[0029] As Figure 6 shown, a first T-shaped sliding groove 6 is formed on the lower end surface of the mounting base 2, and a support rod 7 is slidably arranged inside the first T-shaped sliding groove 6. Specifically, a first T-shaped sliding block 17 is slidably installed inside the first T-shaped sliding groove 6, and the support rod 7 is hinged to the bottom end of the first T-shaped sliding block 17. The support rod 7 can be retracted and unfolded, which not only saves space but also facilitates angle adjustment.

[0030] As Figure 8 shown, a second T-shaped sliding groove 8 is formed on the upper end surface of the base 1, and a second T-shaped sliding block 9 is installed in the second T-shaped sliding groove 8 in a limited sliding manner. Specifically, limiting grooves 18 are evenly formed on both sides of the inner wall of the second T-shaped sliding groove 8, circular grooves 19 are formed on both sides of the second T-shaped sliding block 9, limiting rods 20 are slidably installed inside the circular grooves 19, the limiting rods 20 are inserted and matched with the limiting grooves 18, and a first spring 21 is fixedly connected to the inside of each circular groove 19. The other end of the first spring 21 is fixedly connected to the limiting rod 20. Through grooves are formed on both sides of the upper end surface of the second T-shaped sliding block 9, and shifting blocks 22 are slidably arranged inside the through grooves. The shifting blocks 22 are fixedly connected to the corresponding limiting rods 20.

[0031] As Figure 8 shown, one end of the support rod 7 away from the first T-shaped sliding groove 6 is inserted and matched with the second T-shaped sliding block 9. Specifically, a groove 23 is formed on the upper end surface of the second T-shaped sliding block 9, and the bottom end of the support rod 7 is inserted and matched with the groove 23.

[0032] As Figure 5 As Figure 7 shown, a first sliding groove 10 is formed inside the base 1 corresponding to the position of the mounting groove 4, a contact plate 11 is slidably installed inside the first sliding groove 10, and through holes 12 corresponding to the rollers 5 are formed on the contact plate 11. Initially, the through holes 12 on the contact plate 11 do not correspond to the rollers 5, and the moving blocks 25 and the rollers 5 are located below the contact plate 11. Due to the contact of the contact plate 11, the rollers 5 and the moving blocks 25 cannot move upward inside the mounting groove 4, thereby ensuring that the rollers 5 are in direct contact with the ground when the device is in a movable state.

[0033] As Figure 5 As Figure 8As shown, a linkage assembly is provided between the second T-shaped slider 9 and the abutment plate 11. The linkage assembly includes a tooth plate 13 and a gear 14. A second slide groove 15 is provided inside the base 1 corresponding to the lower portion of the second T-shaped slider 9. The tooth plate 13 is slidably mounted inside the second slide groove 15. The tooth plate 13 is fixedly connected to the bottom end of the second T-shaped slider 9. Gears 14 are rotatably mounted at positions inside the base 1 corresponding to the abutment plate 11. A tooth groove 16 is provided on the side wall of the abutment plate 11. The bottom end of the side wall of the gear 14 is meshed with the tooth groove 16, and the top end of the side wall of the gear 14 is meshed with the tooth plate 13.

[0034] In the initial state, the clearance hole 12 of the abutment plate 11 and the roller 5 are in a misaligned position, and the moving block 25 and the roller 5 are confined in the space below the abutment plate 11. Since the solid part of the abutment plate 11 forms a mechanical barrier to the moving block 25, the roller 5 and the moving block 25 are firmly confined in the lower position of the installation groove 4 under the preload of the second spring 26, ensuring that the bearing surface of the roller 5 protrudes from the lower surface of the base 1, providing good mobile support for the equipment. At this time, the whole system is in a freely movable state, and the operator can easily push the equipment to the desired working position.

[0035] When the solar panel 3 needs to be fixed and the angle needs to be adjusted, the operator first turns the mounting base 2 upwards with the hinge axis between the base 1 and the mounting base 2 as the rotation center. In the initial stage of turning, the support rod 7 originally stored in the first T-shaped slide groove 6 will automatically slide out with the turning action. The operator needs to accurately align the connector at the bottom of the support rod 7 with the groove 23 on the second T-shaped slide block 9 and apply pressure to complete the plug-in fit.

[0036] During the angle adjustment stage, the operator needs to simultaneously pinch the two side blocks 22 to allow the limit rod 20 to overcome the elastic force of the first spring 21 and completely escape from the limit slot 18. After unlocking, the second T-shaped slider 9 is pushed axially along the second T-shaped slide slot 8. During the advancement process, the angle of the mounting seat 2 changes by about 5° for every 10mm of movement. When the second T-shaped slider 9 moves to a position 100-150mm away from the hinge axis, the mounting seat 2 can reach the optimal working angle (usually 30-45°).

[0037] During the movement of the second T-shaped slider 9, the tooth plate 13 connected to its bottom moves synchronously. The tooth plate 13 adopts a modular tooth segment design, with an effective meshing length of 80 mm and a tooth profile of an involute tooth profile with a pressure angle of 20°. When the tooth plate 13 moves, its teeth form a precise meshing with the gear 14, and the transmission ratio is set to 1:1. The rotation of the gear 14 drives the tooth groove 16 meshing with it to cause the abutment plate 11 to produce a lateral displacement. The displacement is accurately calculated to ensure that the clearance hole 12 can be completely aligned with the axis of the roller 5.

[0038] When the abutment plate 11 moves to the end of the designed stroke, the toothless section of the tooth plate 13 just reaches the meshing position, and the gear 14 automatically disengages from the transmission state. This ingenious design allows the abutment plate 11 to stop accurately at the predetermined position, allowing the positioning hole 12 to fully align with the center line of the roller 5. At this time, the pre-compressed second spring 26 releases its elastic force, pushing the moving block 25 to drive the roller 5 to rise steadily, and finally the roller 5 is completely retracted into the installation groove 4, so that the lower surface of the base 1 is in full contact with the ground.

[0039] The entire linkage process has three key mechanical characteristics: first, the progressive meshing design is adopted to ensure smooth transmission without impact; second, a hard limit structure is set to limit the maximum displacement of the abutment plate 11; third, the linearity of each moving part is ensured by the precision-machined guide groove. These designs make the system state switching time control quickly completed in a short time, simple operation, and improve work efficiency.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
