Abstract
Description
Technical Field
[0001] This application relates to the field of solar energy support technology, and in particular to a limiting component and a photovoltaic tracking bracket. Background Technology
[0002] Photovoltaic power generation devices are one of the most important forms of solar energy utilization today. Based on the photovoltaic effect, they directly convert sunlight into electrical energy. Existing photovoltaic power generation devices typically use photovoltaic tracking brackets to support and fix the photovoltaic modules. The main beam on the tracking bracket can drive the photovoltaic modules to rotate as the sun moves, ensuring that sunlight hits the photovoltaic modules as perpendicularly as possible.
[0003] In related technologies, the tracking angle of photovoltaic (PV) tracking brackets needs to be limited to prevent excessively large tracking angles from increasing the windward area of the PV modules and resulting in greater wind loads on the brackets. In extreme weather conditions, this could even damage the modules or the brackets. Therefore, a limiting component and a PV tracking bracket need to be designed to address these issues.

[0036] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.
[0037] like Figures 1-5 As shown, in a first aspect, embodiments of this application may provide a limiting member for restricting the rotation angle of the main beam 3. This limiting member may include:
[0038] The limiting cylinder 1 has a limiting through hole 11 through it, and the main beam 3 rotates and passes through the limiting through hole 11; the main beam 3 has an edge length 4, and the two ends of the edge length 4 rotate in contact with the inner wall of the limiting through hole 11.
[0039] The limiting part 2 is provided on the inner wall of the circumferential arc corresponding to the edge length 4 and can abut against the edge length 4; the limiting part 2 is used to limit the rotation angle of the main beam 3 in the limiting cylinder 1.
[0040] In this embodiment, the limiting member is disposed on the side of the bearing seat 5. The main beam 3 passes through the limiting cylinder 1 and is rotatably disposed in the bearing seat 5. During the rotation of the main beam 3, the limiting part 2 will abut against the edge length 4 of the main beam 3 to limit the circumference of the main beam 3, that is, to limit the rotation angle of the main beam 3, thereby improving the problem of the main beam 3 being damaged due to excessive rotation angle.
[0041] It should be noted that the cross-sectional shape of the main beam 3 is not circular. In this embodiment, the cross-sectional shape of the main beam 3 is square. As the main beam 3 rotates, the first position of the edge length 4 of the main beam 3 is abutted by the limiting part 2 in the limiting cylinder 1, thereby restricting the rotation of the main beam 3 in the limiting cylinder 1. When the main beam 3 rotates in the opposite direction, the limiting part 2 abuts against the second position of the edge length 4, thereby restricting the rotation of the main beam 3 in the limiting cylinder 1, thus realizing the limitation of the rotation angle of the main beam 3 by the limiting member. It is worth mentioning that the distance from the first position to the second position corresponds to the central angle of the circumferential arc of 60°, that is, the rotation angle of the main beam 3 in the cylinder 1 is limited to no more than 60°.
[0042] In an optional embodiment, the limiting part 2 includes a first arc curve 21, a second arc curve 22, and a limiting protrusion 23. The ends of the first arc curve 21 and the second arc curve 22 that are far apart from each other are both connected to the limiting cylinder 1. The sides of the first arc curve 21 and the second arc curve 22 that face each other extend toward the axis of the limiting through hole 11 and connect to form the limiting protrusion 23. The end of the limiting protrusion 23 that is close to the axis of the limiting through hole 11 can abut against the edge length 4.
[0043] In this embodiment, the first arc curve 21 and the second arc curve 22 are arranged to protrude outward in the circumferential direction of the limiting cylinder 1, and the side of the first arc curve 21 and the second arc curve 22 facing each other extends towards the axis of the limiting through hole 11 and connects to form the limiting protrusion 23. The limiting protrusion 23 can limit the rotation angle of the main beam 3 by abutting against the edge length 4.
[0044] In an optional embodiment, the central angles corresponding to the first circular arc curve 21 and the second circular arc curve 22 are 15°~20° respectively and independently.
[0045] In this embodiment, the central angles corresponding to the first arc curve 21 and the second arc curve 22 can be the same. When the central angles corresponding to the first arc curve 21 and the second arc curve 22 are 15°~20° respectively and independently, the height of the limiting protrusion 23 can achieve the limiting effect on the rotation of the main beam 3. When the central angles corresponding to the first arc curve 21 and the second arc curve 22 are both less than 15°, the height of the limiting protrusion 23 is insufficient to achieve the limiting effect on the rotation of the main beam 3. When the central angles corresponding to the first arc curve 21 and the second arc curve 22 are both greater than 20°, the limiting protrusion 23 will rub against the edge length 4 due to its excessive height during the rotation of the main beam 3, resulting in excessive resistance to the main beam 3 during the rotation and affecting its normal movement.
[0046] In an optional embodiment, both the first arc curve 21 and the second arc curve 22 are integrally formed with the limiting cylinder 1. The integral forming design of the first arc curve 21 and the second arc curve 22 with the limiting cylinder 1 facilitates the mass production of the limiting component.
[0047] In an optional embodiment, the limiting part 2 includes a limiting ridge 24; the limiting ridge 24 is disposed on the inner wall forming the limiting through hole 11 along the axial direction parallel to the limiting through hole 11; one end of the limiting ridge 24 near the axis of the limiting through hole 11 can abut against the ridge length 4.
[0048] In this embodiment, the limiting rib 24 can be integrally formed with the limiting cylinder 1, and one end of the limiting rib 24 near the axis of the limiting through hole 11 can abut against the rib length 4, thereby realizing the limiting effect on the main beam 3 during rotation.
[0049] In an optional embodiment, the height of the limiting ridge 24 is 100~200mm.
[0050] In this embodiment, when the height of the limiting edge 24 is less than 100mm, it cannot effectively limit the main beam 3. The main beam 3 will exceed the predetermined rotation angle due to inertia or external force. When the limiting edge 24 is higher than 200mm, the excessively high limiting edge 24 will rub against the edge length 4, which will cause the main beam 3 to be subjected to too much resistance during rotation, affecting its normal movement and reducing the service life of the main beam 3.
[0051] In an optional embodiment, a connecting piece 12 is provided on the periphery of the limiting cylinder 1, and the connecting piece 12 is used to connect with the bearing seat 5.
[0052] In this embodiment, the connecting piece 12 can be connected to the side of the bearing seat 5 by bolts, screws or welding, so that the limiting cylinder 1 and the bearing seat 5 are arranged coaxially, thus completing the installation of the limiting component.
[0053] In an optional embodiment, the number of connecting pieces 12 is several, and the several connecting pieces 12 are evenly spaced on the periphery of the limiting cylinder 1. The multiple connecting pieces 12 spaced apart can improve the stability of the limiting member installation.
[0054] In an optional embodiment, the number of limiting parts 2 is several, and each limiting part 2 is evenly spaced on the inner wall forming the limiting through hole 11; the number of limiting parts 2 is consistent with the number of edge lengths 4.
[0055] In this embodiment, the arrangement of multiple limiting parts 2 can improve the stability of limiting the rotation angle of the main beam 3, reduce the situation where the main beam 3 exceeds the predetermined rotation angle due to inertia or external force, and ensure the safe operation of the tracking bracket.
[0056] Secondly, embodiments of this application may provide a photovoltaic tracking bracket, comprising:
[0057] The bearing housing 5, bearing 6, main beam 3, column 7, and limiting member of any of the above embodiments; the bearing housing 5 is disposed on the column 7, the bearing 6 is rotatably disposed in the bearing housing 5, the main beam 3 is disposed in the bearing 6, and the main beam 3 rotates synchronously with the bearing 6; the limiting member is disposed on one side of the bearing housing 5 and is used to limit the rotation angle of the main beam 3.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0059] For ease of description, directional terms such as "front, back, up, down, left, right," "horizontal, vertical, horizontal," and "top, bottom" generally indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as limiting the scope of protection of this application. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the components themselves. For example, if a device in the drawings is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.
[0060] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0061] Unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0062] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0063] It should also be noted that the terms "one embodiment," "another embodiment," or "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.
[0064] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0065] It should also be noted that the above are merely preferred embodiments of this application and do not limit the scope of patent protection of this application. Any equivalent structural or procedural changes made using the content of this application’s specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
