Abstract
Description
Technical Field
[0001] This application belongs to the field of photovoltaic cell technology, and in particular relates to a clamping device and a photovoltaic support. Background Technology
[0002] A photovoltaic (PV) support system includes bearings and a torque beam. The bearings are mainly used to support the PV panels and allow them to rotate around the bearings, so that the PV panels can be adjusted at an angle according to the position of the sun to achieve the best lighting effect. The torque beam is a long beam that connects the bearings and the PV panels and is used to transmit and distribute the rotational torque of the bearings.
[0003] However, the fit between existing bearings and torque beams is highly dependent on fixed dimensions and shapes. Once the specifications (shape or outer diameter) of the torque beam change, existing bearings may not be able to be installed with the torque beam or provide sufficient support, leading to the need for bearing redesign or replacement, resulting in poor bearing versatility.
[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content
[0005] This application provides a clamping device and a photovoltaic bracket to solve or alleviate one or more technical problems in the prior art.
[0006] The first aspect of this application provides a clamping device for clamping a torque beam supporting a solar cell, the clamping device comprising:
[0007] First cover plate;
[0008] A rotating plate with a through hole in the center for the torque beam to pass through is located on one side of the first cover plate, and the rotating plate is also provided with an arc-shaped hole.
[0009] A rotating blade is disposed on the side of the rotating plate facing the first cover plate. The rotating blade is provided with a connecting hole that communicates with the arc-shaped hole. The projection of the rotating blade and the through hole along the axial direction at least partially overlaps.
[0010] The second cover plate is disposed on the side of the rotating plate away from the first cover plate and is fixedly connected to the first cover plate. A fixing post is provided on one side of the second cover plate, and the fixing post passes through the connecting hole and the arc-shaped hole.
[0011] With the torque beam passing through the through hole, the rotating plate can rotate along its axis, causing the fixed column to move relative to the rotating plate along the arc-shaped hole, thereby driving the rotating blade to rotate, so that the rotating blade abuts against the torque beam.
[0012] Optionally, the first cover plate has a protruding edge on the side facing the second cover plate, the protruding edge surrounding the periphery of the first cover plate to form a receiving groove for accommodating the rotating plate.
[0013] Optionally, an arc-shaped notch is provided on the convex edge to form two opposing cross-sections on the convex edge;
[0014] The clamping device further includes:
[0015] An extension plate, one end of which is connected to the rotating plate, and the other end of which extends out along the arc-shaped notch of the convex edge, wherein the width of the arc-shaped notch is greater than the width of the extension plate;
[0016] An elastic element is connected between a side end of the extension plate and a cross section of the convex edge.
[0017] Optionally, the rotating plate is a circular plate, and the edge of the rotating plate has a straight tangent edge, the straight tangent edge having a first end and a second end opposite to each other;
[0018] The arc-shaped hole has a first end and a second end that are opposite each other;
[0019] The straight distance between the first end of the straight tangent and the first end of the arc-shaped hole is the first distance, and the straight distance between the second end of the straight tangent and the second end of the arc-shaped hole is the second distance;
[0020] Wherein, the first distance is greater than the second distance.
[0021] Optionally, one end of the rotating blade extends beyond the straight tangent edge of the rotating plate, and the extended portion has a retaining edge that extends away from the first cover plate and is close to the straight tangent edge.
[0022] Optionally, the rotating blade includes a contact end for abutting against the torque beam, and the contact end is provided with serrations.
[0023] Optionally, there are four rotating blades, which are evenly distributed around the circumference of the rotating plate.
[0024] A second aspect of this application provides a photovoltaic bracket, including a clamping device as described in any of the preceding claims.
[0025] Optionally, there are two clamping devices;
[0026] The photovoltaic support also includes:
[0027] A spherical bearing, the spherical bearing comprising an arcuate side surface and two opposing planar end faces, each of the planar end faces being fixedly connected to one of the clamping devices;
[0028] A mounting base surrounds the arcuate side of the spherical bearing.
[0029] Optionally, the area of the planar end face of the spherical bearing is smaller than the area of the side of the clamping device facing the planar end face.
[0030] The embodiments of this application employing the above-described technical solution may have the following advantages:
[0031] With the torque beam passing through the through hole, the rotating plate can rotate along its axis, causing the fixed column to move relative to the rotating plate along the arc-shaped hole. This drives the rotating blades to rotate, causing the rotating blades to press against the torque beam. The rotating blades are used to contact the torque beam and apply clamping force. The rotating blades can partially block the opening of the through hole during rotation, creating an adjustable clamping space. The rotation of the rotating blades allows the size and shape of the through hole to be adjusted according to changes in the outer diameter of the torque beam, enabling the rotating blades to firmly abut against the outer wall of the beam. The rotating blades provide a variable clamping surface during clamping, accommodating torque beams of different shapes and outer diameters.
[0032] The clamping device in this embodiment can be installed on the side of the bearing of the photovoltaic bracket to clamp the torque beam passing through the bearing. For torque beams with different shapes and outer diameters, the clamping device can rotate the rotating plate to drive the rotating blade to rotate, thereby changing the area of the rotating blade blocking the through hole, thus adjusting the shape and size of the through hole. The rotating blade can also abut against the outer wall of the torque beam to clamp torque beams with different shapes and outer diameters. The device has high overall versatility.

[0050] This application provides a clamping device and a photovoltaic support technical solution. This addresses the problem of poor versatility of bearings. See below for details.
[0051] 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.
[0052] Please see Figures 1 to 6 This application provides a clamping device for clamping a torque beam supporting a solar cell. The clamping device includes a first cover plate 11, a rotating plate 13, a rotating blade 14, and a second cover plate 12. Detailed description follows:
[0053] The first cover plate 11 and the second cover plate 12 are used to provide a limit, clamping and restricting the rotating plate 13 and the rotating blade 14 between the first cover plate 11 and the second cover plate 12.
[0054] The rotating plate 13 has a through hole 131 at its center for the torque beam to pass through. The rotating plate 13 is located on one side of the first cover plate 11. The rotating plate 13 also has an arc-shaped hole 133.
[0055] A rotating blade 14 is disposed on the side of the rotating plate 13 facing the first cover plate 11. The rotating blade 14 has a connecting hole 141 communicating with the arc-shaped hole 133. The projections of the rotating blade 14 and the through hole 131 along the axial direction at least partially overlap. When the rotating blade 14 rotates along the length direction of the arc-shaped hole 133, the overlapping area of the projections of the rotating blade 14 and the through hole 131 along the axial direction changes. The end face of the rotating blade 14 that contacts the torque beam can be a convex arc surface. Compared with a planar contact surface, the arc surface can better adapt to the shape of the torque beam.
[0056] The second cover plate 12 is disposed on the side of the rotating plate 13 away from the first cover plate 11 and is fixedly connected to the first cover plate 11. A fixing post 121 is provided on one side of the second cover plate 12, and the fixing post 121 passes through the connecting hole 141 and the arc-shaped hole 133. When the rotating plate 13 rotates, the arc-shaped hole 133 and the fixing post 121 move relative to each other, which can be regarded as the fixing post 121 moving within the arc-shaped hole 133. The shape of the arc-shaped hole 133 limits the fixing post 121, thereby limiting the travel direction of the fixing post 121, and thus limiting the rotation direction of the rotating blade 14, so as to drive the rotating blade 14 to open and close. In some embodiments, corresponding threaded holes can be provided on both the first cover plate 11 and the second cover plate 12 to connect the first cover plate 11 and the second cover plate 12 by connecting parts such as screws / rivets.
[0057] With the torque beam passing through the through hole 131, the rotating plate 13 can rotate along its axis, causing the fixed post 121 to move relative to the rotating plate 13 along the arc-shaped hole 133, thereby driving the rotating blade 14 to rotate so that the rotating blade 14 abuts against the torque beam. The rotating blade 14 is used to contact the torque beam and apply clamping force. The rotating blade 14 can partially block the opening of the through hole 131 during rotation, forming an adjustable clamping space. By rotating the rotating blade 14, the size and shape of the through hole 131 can be adjusted according to the change of the outer diameter of the torque beam, so that the rotating blade 14 can be firmly abutted against the outer wall of the beam. The rotating blade 14 provides a variable clamping surface during clamping, which can accommodate torque beams of different shapes and outer diameters.
[0058] The clamping device in this embodiment can be installed on the side of the bearing of the photovoltaic bracket to clamp the torque beam passing through the bearing. For torque beams with different shapes and outer diameters, the clamping device can rotate the rotating plate 13 to drive the rotating blade 14 to rotate, thereby changing the area of the rotating blade 14 blocking the through hole 131, thus adjusting the shape and size of the through hole 131. The rotating blade 14 can also abut against the outer wall of the torque beam to clamp torque beams with different shapes and outer diameters, making it highly versatile.
[0059] Furthermore, in this embodiment, the first cover plate 11 has a protruding edge 111 on the side facing the second cover plate 12, and the protruding edge 111 surrounds the periphery of the first cover plate 11 to form a receiving groove 115, which is used to receive the rotating plate 13.
[0060] The receiving groove 115 can be used to limit the rotation plate 13, preventing it from shaking or shifting during rotation and ensuring that the rotation plate 13 is always in the correct position. Furthermore, the receiving groove 115 formed by the protruding edge 111 can seal the surrounding space of the rotation plate 13, protecting it. The protruding edge 111 can effectively prevent dust, sand, or other foreign objects from entering the gap between the rotation plate 13 and the first cover plate 11, avoiding wear or jamming caused by the accumulation of foreign objects. The receiving groove 115 also provides positioning for the installation of the rotation plate 13, facilitating the operator's assembly of the rotation plate 13.
[0061] Further, please refer to Figure 2 An arc-shaped notch 113 is provided on the protruding edge 111 to form two opposing cross-sections on the protruding edge 111.
[0062] The clamping device further includes an extension plate 16 and an elastic element 17. One end of the extension plate 16 is connected to the rotating plate 13, and the other end extends along the arc-shaped notch 113 of the protruding edge 111. The width of the arc-shaped notch 113 is greater than the width of the extension plate 16, so that the extension plate 16 can move within the arc-shaped notch 113. The elastic element 17 spans between the side end of the extension plate 16 and a cross section of the protruding edge 111.
[0063] The elastic element 17 is connected between the side end of the extension plate 16 and the cross section of the protrusion 111. When the rotating plate 13 drives the extension plate 16 to rotate, the elastic element 17 is compressed. The elastic potential energy generated by the compression of the elastic element 17 will provide a thrust to the extension plate 16. On the one hand, it can drive the extension plate 16 to reset, and on the other hand, it can drive the rotating blade 14 to keep clamped.
[0064] In addition, the elastic element 17 can also reduce the mechanical wear of the clamping device. The elastic element 17 can smoothly absorb and disperse the impact force during the clamping and releasing process, thereby reducing the rigid stress on the clamping device during use, reducing wear, and reducing maintenance frequency and cost.
[0065] Specifically, the elastic element 17 can be a spring, and the inner wall of the arc-shaped notch 113 can be provided with an arc-shaped groove to accommodate the elastic element 17 and limit the compression and elastic direction of the elastic element 17.
[0066] In this embodiment, the extension plate 16 extends along the arc-shaped notch 113 of the protruding edge 111, and the rotating plate 13 can be rotated by driving the extension plate 16.
[0067] In an alternative embodiment, please combine Figures 2 to 4 See Figure 5The rotating plate 13 is a circular plate, and the edge of the rotating plate 13 has a straight tangent 135. The straight tangent 135 has a first end and a second end opposite to each other, and the arc-shaped hole 133 has a first end and a second end opposite to each other.
[0068] The straight-line distance between the first end of the straight cut edge 135 and the first end of the arc-shaped hole 133 is a first distance, and the straight-line distance between the second end of the straight cut edge 135 and the second end of the arc-shaped hole 133 is a second distance. The first distance is greater than the second distance.
[0069] Since the first distance is greater than the second distance, when the rotating plate 13 rotates along the first direction, the rotating blade 14 rotates along the arc-shaped hole 133 toward the central region away from the rotating plate 13, thereby reducing the overlap between the rotating blade 14 and the through hole 131, allowing the torque beam to enter the through hole 131. After the torque beam is placed in the through hole 131, during the clamping process, the rotating plate 13 rotates in the opposite direction of the first direction, and the rotating blade 14 rotates along the arc-shaped hole 133 toward the central region of the rotating plate 13, thereby applying uniform pressure to the torque beam.
[0070] Furthermore, in this embodiment, one end of the rotating blade 14 extends out of the straight cut edge 135 of the rotating plate 13, and the extended portion has a retaining edge 143, which extends toward the side away from the first cover plate 11 and closely abuts the straight cut edge 135.
[0071] When the rotating blade 14 rotates, the flange 143 can limit the end of the rotating blade 14. When one end of the rotating blade 14 is limited, the rotating blade 14 can swing around the flange 143 as the center when it rotates along the arc hole 133, thereby further limiting the rotation path of the rotating blade 14 and ensuring the stability of the rotating blade 14 clamping the torque beam.
[0072] The rotating blade 14 includes a contact end for abutting against the torque beam, and the contact end is provided with serrations 145.
[0073] The serrations 145 on the rotating blade 14 increase the friction between the rotating blade 14 and the torque beam, thereby enabling the rotating blade 14 to better adapt to torque beams of different shapes and surface characteristics. Whether the surface is smooth or rough, the serrations 145 provide better gripping ability, ensuring that the rotating blade 14 can firmly press against the torque beam under different conditions, preventing the torque beam from slipping due to vibration or external forces, thus improving the stability of clamping.
[0074] In some embodiments, a silicone contact layer can be provided at the contact end of the rotating blade 14. The silicone contact layer has good frictional properties, which can increase the contact friction between the rotating blade 14 and the torque beam. Furthermore, the silicone can better adapt to torque beams of different shapes and surfaces. When the surface of the torque beam has minor unevenness or irregularities, the softness of the silicone allows it to fill these gaps, thereby ensuring a tighter contact and improving the clamping effect. Moreover, because the silicone is soft, it can prevent the rotating blade 14 from directly and rigidly contacting the torque beam, reducing the possibility of indentations on the torque beam when the rotating blade 14 clamps it.
[0075] In a preferred embodiment, there are four rotating blades 14, which are evenly distributed around the circumference of the rotating plate 13. That is, the center point of each rotating blade 14 and the center point of the through hole 131 form a straight line, and the included angle between any two adjacent straight lines is 90°.
[0076] When clamping the torque beam, the clamping force applied by the four rotating blades 14 can be evenly distributed across multiple contact points of the torque beam. On the one hand, this ensures that the torque beam is subjected to a uniform clamping force, preventing rotation or displacement of the torque beam, and also evenly distributing the clamping force on the torque beam, avoiding wear caused by excessive stress at a single contact point. On the other hand, it avoids localized over-clamping or slackness, thereby improving the clamping effect and overall stability.
[0077] Furthermore, the presence of multiple rotating blades 14 makes clamping and releasing actions simpler and more efficient. Simply rotating the rotating plate 13 can drive the four rotating blades 14 to open and close simultaneously, achieving rapid clamping and releasing and improving the ease of operation.
[0078] In other embodiments, the number of rotating blades 14 can also be other numbers, such as three, five, six, eight, etc., and the multiple rotating blades 14 can be evenly distributed along the circumference of the rotating plate 13.
[0079] This application also provides a photovoltaic bracket, including the clamping device 100 in any of the above embodiments.
[0080] Specifically, please refer to Figure 7 and Figure 8 In this embodiment, there are two clamping devices 100, and the photovoltaic bracket also includes a ball bearing 32 and a fixing seat 31.
[0081] The spherical bearing 32 includes an arcuate side surface 321 and two opposing planar end surfaces 322, each of the planar end surfaces 322 being fixedly connected to one of the clamping devices 100. The fixing seat 31 surrounds the arcuate side surface 321 of the spherical bearing 32.
[0082] A connecting post can be provided on the flat end face 322 of the ball bearing 32. The connecting post passes through the first cover plate and the second cover plate of the clamping device 100 in sequence, so as to connect the first cover plate and the second cover plate to the side of the ball bearing 32.
[0083] The fixed base 31 may include two arc-shaped clamps that enclose a hollow ring structure to accommodate the ball bearing 32.
[0084] The mounting base 31 surrounds the spherical bearing 32 and is fixed to the external structure to provide support for the spherical bearing 32. The spherical bearing 32 is installed in the mounting base 31 and is used for the torque beam to pass through. When the torque beam passes through the spherical bearing 32, the clamping devices 100 on both sides of the spherical bearing 32 can clamp the torque beam to prevent the torque beam from shaking.
[0085] Specifically, the outer ring (i.e. the arc-shaped side 321) of the spherical bearing 32 can be lubricated so that the spherical bearing 32 can rotate around its axis. At the same time, the spherical bearing 32 can drive the torque beam to rotate, thereby driving the photovoltaic panel supported by the photovoltaic bracket to rotate.
[0086] Furthermore, in this embodiment, the area of the planar end face 322 of the ball bearing 32 is smaller than the area of the side of the clamping device 100 facing the planar end face 322, that is, the area of the planar end face 322 of the ball bearing 32 is smaller than the area of the first cover plate or the second cover plate.
[0087] like Figure 8 As shown, when the ball bearing 32 deflects, because the end face of the clamping device 100 is large, when it rotates to a predetermined angle, one end face of the clamping device 100 will abut against the fixed seat 31, thereby limiting the deflection of the ball bearing 32 and preventing the ball bearing 32 from deflecting excessively and falling out of the fixed seat 31.
[0088] When adjusting the large angle of the north and south slope groups of the photovoltaic panel, the clamping devices on both sides of the spherical bearing can play a role in blocking and limiting, thereby improving the problem of the spherical bearing falling off.
