Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic damping technology, and in particular relates to an electromagnetic damping for adjustable photovoltaic brackets. Background Technology

[0002] In photovoltaic (PV) power generation applications, PV modules are typically mounted on adjustable supports. These supports periodically adjust the tilt angle of the modules to increase the amount of solar radiation received by the modules throughout the year, thereby increasing the annual power generation. However, because the rotation angle of the adjustable supports is adjustable, PV modules are significantly affected by wind during windy weather. During normal power generation, wind can prevent PV modules from receiving direct sunlight, thus hindering their ability to reach maximum power generation efficiency. Utility Model Content

[0003] To address the problem described in the background art of existing adjustable photovoltaic supports being difficult to generate stable power due to wind influence, this utility model proposes the following technical solution:

[0004] An electromagnetic damper for an adjustable photovoltaic bracket includes: a protective cover, multiple electromagnets, multiple sets of coils, and a rotating shaft; the surface of the protective cover is provided with a guide hole, the interior of the protective cover is provided with an annular cavity, and the outer side of the protective cover is fixedly mounted on the photovoltaic bracket; each electromagnet is arranged in pairs in the annular cavity, and each electromagnet is arranged circumferentially around the inner annular surface of the annular cavity with the guide hole as the center; each set of coils is wound around the corresponding electromagnet, and the rotating shaft passes through the guide hole and is rotatably connected to the external photovoltaic bracket; multiple solar photovoltaic panels are fixedly mounted on the outer circumference of the rotating shaft.

[0005] Furthermore, the included angles between each electromagnet are equal, and the dimension of the side of each electromagnet closer to the annular cavity is larger than the dimension of the side of each electromagnet closer to the guide hole.

[0006] Furthermore, the annular cavity protrudes to form a boss coaxial with the protective cover, and the guide hole passes through the boss and is coaxial with the boss.

[0007] Furthermore, each of the electromagnets has the same thickness, and the thickness of each of the electromagnets is less than the thickness of the boss.

[0008] Furthermore, the end face of each electromagnet is an arc surface, and the end faces on the same side of each electromagnet are located on the same arc surface.

[0009] Beneficial effects: This utility model uses an electromagnet installed inside the protective cover and a photovoltaic support to form a damper, which stabilizes the installation tilt angle of the solar photovoltaic panel under the action of electromagnetic force to resist the action of external wind force.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

Figure 2 This is a schematic diagram of the internal structure of an electromagnetic damper for an adjustable photovoltaic bracket according to an embodiment of the present invention.

[0015] Reference Figure 1 An electromagnetic damper for an adjustable photovoltaic bracket according to an embodiment of the present invention includes: a protective cover 1, multiple electromagnets 2, multiple sets of coils 2, and a rotating shaft 3. The protective cover 1 is generally cylindrical, with its narrow outer surface fixed to the photovoltaic bracket, and a guide hole 12 provided on its wide outer surface. An annular cavity 11 is provided inside the protective cover 1, and the annular cavity 11 is not connected to the guide hole 12. (Refer to...) Figure 2Each electromagnet 2 is arranged in pairs within the annular cavity 11, and each electromagnet 2 is arranged circumferentially around the inner annular surface of the annular cavity 11 with the guide hole 12 as the center. Each set of coils 2 is respectively sleeved on the corresponding electromagnet 2 to form electrodes. The rotating shaft 3 passes through the guide hole 12 and is rotatably connected to the external photovoltaic bracket. The rotating shaft 3 is rotatably mounted on the photovoltaic bracket through bearings and other components, and multiple solar photovoltaic panels are arranged in an array on the outer circumference of the rotating shaft 3.

[0016] Specifically, a boss 13, coaxial with the protective cover 1, protrudes within the annular cavity 11. The entire boss 13 is cylindrical, and a guide hole 12, coaxial with the boss 13, passes through its center. The thickness of the boss 13 is greater than the thickness of each electromagnet 2, and each electromagnet 2 is located between the outer peripheral wall of the boss 13 and the inner sidewall of the protective cover 1. The portion of the rotating shaft 3 passing through the guide hole 12 serves as the rotor of the entire damper within the annular cavity 11, while each electromagnet 2 acts as the stator of the entire damper. When the solar photovoltaic panel on the rotating shaft 3 rotates under wind force, the resistance generated between each set of electromagnets 2 hinders the rotational tendency of the rotating shaft 3, thereby stabilizing the posture of the solar photovoltaic panel installed on the rotating shaft 3. During power generation, the rotating shaft 3 is driven to rotate by setting an induced current flowing into the coil 2, so as to maintain a suitable tilt angle during photovoltaic power generation.

[0017] Each electromagnet 2 has an arc-shaped end face and a fan-shaped block structure. The included angle between adjacent electromagnets 2 is equal, and the diameter of the side of each electromagnet 2 closest to the inner wall of the protective cover 1 is larger than the diameter of the side of each electromagnet 2 closest to the boss 13. The end faces of each electromagnet 2 closest to the boss 13 are all located on the same arc surface, and the end faces of each electromagnet 2 closest to the inner wall of the protective cover 1 are all located on a uniform arc surface. The electromagnets 2 are arranged at intervals, and each electromagnet 2 is coupled to a set of coils 2. The coils 2 in each electromagnet 2 have the same winding direction. Each set of coils 2 is connected to an external power supply and a control system to control the rotation of the shaft 3.

[0018] In summary, this utility model uses an electromagnet installed inside the protective cover and a photovoltaic support to form a damper, which stabilizes the installation tilt angle of the solar photovoltaic panel under the action of electromagnetic force to counteract the effects of external wind.
