Description

Technical Field

[0001] This invention relates to the field of tracking bracket technology, and in particular to a limiting mechanism for a tracking bracket and a photovoltaic tracking bracket. Background Technology

[0002] Photovoltaic tracking brackets, as structural devices specifically designed for photovoltaic power generation systems, primarily function to support and fix photovoltaic modules (such as solar panels). They also automatically or manually adjust according to the sun's trajectory to maximize the angle and time at which the photovoltaic modules receive solar radiation, thereby improving power generation efficiency. This type of bracket system not only requires sufficient strength and stability to withstand external forces under various climatic conditions, but also needs good corrosion resistance and durability to ensure long-term stable operation.

[0003] For tracking brackets, one of the major factors causing structural damage is high wind load. Existing tracking brackets have at least one of the following problems when dealing with high winds: 1. Using only a single worm gear reducer located in the middle of a single row as a self-locking point, the torque tube far from the middle position is prone to deformation and damage under strong wind conditions; 2. Although some manufacturers have set up corresponding wind protection strategies, choosing to stop at a small angle (i.e., when the photovoltaic modules are near the flat position) to reduce wind load or at a large angle (i.e., at the extreme angle of the tracking bracket rotation) to provide more locking point protection, the corresponding time to rotate to a small or large angle is relatively long because it is impossible to accurately judge the time when the strong wind will arrive. During the process of rotating to a small or large angle, the bracket structure may be damaged. 3. Existing technologies employ multi-point electrical drives to rotate the tracking bracket. These drives use the unidirectional self-locking function of multiple synchronously rotating worm gear reducers to lock at any angle. However, due to the use of multiple drives and the need for communication between them to achieve synchronous rotation, the cost is high and it is not suitable for large-scale promotion and use. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, a limiting mechanism for a tracking bracket and a photovoltaic tracking bracket are provided.

[0005] The specific technical solution is as follows: Design a limiting mechanism for a tracking bracket to limit the torque tube in the tracking bracket, including: The locking element is rotatably mounted below the torque tube; The housing has a torque tube suspended from it. The housing is provided with an upper stop area, a first lower stop area, a second lower stop area, and a fracture opening. The fracture opening and the upper stop area are higher than the first lower stop area and the second lower stop area in the vertical direction. The torque tube has a passable state or a first locked state when passing through the first lower stop area and the second lower stop area; the torque tube has a passable state or a second locked state when rotating to the upper stop area; In the first locking state, the locking member is locked at the first lower stop region or the second lower stop region in an inclined state; in the second locking state, the torque tube is locked at the upper stop region. The torque tube switches between the passable state and the first or second locked state by rotating in the opposite direction.

[0006] Preferably, the locking member includes a lock head, the bottom of which is provided with a pointed head that cooperates with the first lower stop area and the second lower stop area for locking.

[0007] Preferably, the bottom of the housing is provided with an arc-shaped plate, and the end of the arc-shaped plate forms a corner structure with the housing.

[0008] Preferably, the first lower stop area is set as the corner area formed between the left end of the arc plate and the shell, and the second lower stop area is set as the corner area formed between the right end of the arc plate and the shell.

[0009] Preferably, the arc-shaped plate is integrally formed with the shell or formed separately.

[0010] Preferably, the locking member is mounted below the torque tube via a locking member mounting member.

[0011] Preferably, the locking component mounting component includes a screw, a screw end, and a first mounting portion. The locking component is mounted below the torque tube via the screw, and the screw passes through the torque tube so that the screw end extends out of the torque tube. The locking component is provided with a second mounting portion that cooperates with the screw end for mounting the locking component.

[0012] Preferably, a suspension part is provided on the top of the housing, and the torque tube is suspended from the housing through the first mounting part and the suspension part.

[0013] Preferably, the cross-section of the torque tube is set to be circular, rectangular, hexagonal, octagonal, D-shaped, or square.

[0014] Preferably, the housing is further provided with a reversing part, which is used to guide the locking member and change the tilt direction of the locking member.

[0015] A photovoltaic tracking bracket includes a limiting mechanism for the aforementioned tracking bracket, and further includes a driving component, a driving column, a first non-driving column, a second non-driving column, and a column adapter. The first non-driving column and the second non-driving column are arranged adjacent to each other. The driving component is installed on the top of the driving column and is fixedly connected to a torque tube via a crank. The housing is fixedly installed on the first non-driving column or the second non-driving column via the column adapter.

[0016] Preferably, the housing includes a first housing mounted on a first non-drive column and a second housing mounted on a second non-drive column, wherein the fracture openings on the first housing and the second housing face the same direction.

[0017] Preferably, the housing includes a first housing mounted on a first non-drive column and a second housing mounted on a second non-drive column, wherein the fracture openings on the first housing and the second housing face the same direction.

[0018] The above technical solution has the following advantages or beneficial effects: The locking structure, formed by the interplay of the locking element and the first and second lower stop areas, allows the tracking bracket to remain open during normal operation. When strong winds occur, it rotates in the opposite direction to enter the locking state, thus locking the torque tube to a safe position. This provides wind protection for the entire tracking bracket and improves its wind resistance. In particular, locking the tracking bracket within a small angle range offers a significant advantage when parking at night, reducing the rotation angle required for the torque tube to reach the first or second lower stop area, thereby quickly achieving locking protection.

[0019] With the upper stop area set on the housing, the tracking bracket has the function of limiting and locking wind resistance at a large angle. When strong winds strike, the tracking bracket can flexibly choose to rotate to a large or small angle to limit and lock according to the current angle. The response time of the tracking bracket rotating from any position to the protection angle is reduced by at least half, which effectively reduces the response time of the tracking bracket rotating to the protection angle, thereby improving the overall safety and wind resistance of the tracking bracket. When the fracture opening is set in the same direction, the wiring can also be directly routed on the torque tube, reducing cable costs.

[0020] By distributing the wind load borne by the overall tracking bracket to multiple columns, the wind load is effectively dispersed, making full use of the structural strength of each column and improving the safety and wind resistance of the overall tracking bracket.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0026] Reference Figures 1-12 A limiting mechanism for a tracking bracket, used to limit the torque tube 1 in the tracking bracket, comprising: Locking element 9 is rotatably mounted below torque tube 1; The housing 2, the torque tube 1 is suspended on the housing 2, the housing 2 is provided with an upper stop area 25, a first lower stop area 81, a second lower stop area 82 and a fracture opening 24, the fracture opening 24 and the upper stop area 25 are higher than the first lower stop area 81 and the second lower stop area 82 in the vertical direction. The torque tube 1 has a passable state or a first locked state when passing through the first lower stop region 81 and the second lower stop region 82; the torque tube 1 has a passable state or a second locked state when rotating to the upper stop region 25. In the first locking state, the locking member 9 is locked at the first lower stop region 81 or the second lower stop region 82 in an inclined state; in the second locking state, the torque tube 1 is locked at the upper stop region 25. Specifically, such as Figures 3-7 As shown, when the torque tube 1 swings along the first swing direction to the first lower preset angle α1, the first lower stop area 81 is used to cooperate with the locking member 9 to make the torque tube 1 in a locked state. When the torque tube 1 swings along the second swing direction to the second lower preset angle α2, the second lower stop area 82 is used to cooperate with the locking member 9 to make the torque tube 1 in a locked state. like Figure 7 As shown, at the top of a single first non-driving column 5 or second non-driving column 6, when the torque tube 1 swings along the first swing direction to an upper preset angle β1, the upper stop area 25 is used to cooperate with the locking member 9 to put the torque tube 1 in a locked state. When the torque tube 1 swings along the second swing direction, it can pass through the fracture opening 24. One of the first swing direction and the second swing direction is clockwise and the other is counterclockwise. The torque tube 1 switches between the passage state and the first locking state or the second locking state by rotating in the opposite direction. For example, when switching from the passage state to the first locking state, when the locking member 9 rotates counterclockwise to the top of the arc plate 8, the locking member 9 tilts to the left. The driving mechanism 10 changes the rotation direction of the torque tube 1 to the clockwise direction, so that the locking member 9 is locked at the second lower locking area 82, forming the first locking state. When it is necessary to enter the passage state from the first locking state, the torque tube 1 is rotated counterclockwise to enter the passage state.

[0027] In some alternative embodiments, the locking member 9 includes a lock head, the bottom of which is provided with a pointed head 91 that cooperates with the first lower stop region 81 and the second lower stop region 82 for locking.

[0028] The lock head has a spindle-shaped pointed head 91. When the lock head is locked in the first lower stop region 81 or the second lower stop region 82, the pointed head 91 on the lock head is in contact with the first lower stop region 81 or the second stop region 82 to prevent the torque tube 1 from continuing to rotate.

[0029] In some alternative embodiments, an arc-shaped plate 8 is provided at the bottom of the housing 2, and the end of the arc-shaped plate 8 forms a corner structure with the housing 2.

[0030] In some alternative embodiments, the first lower stop region 81 is set as the corner region formed between the left end of the arc plate 8 and the housing 2, and the second lower stop region 82 is set as the corner region formed between the right end of the arc plate 8 and the housing 2.

[0031] Specifically, such as Figure 5 , Figure 6 As shown, when the torque tube 1 swings along the first swing direction to the first lower preset angle α1, the first lower stop area 81 is in contact with the pointed head on the lock head to put the torque tube 1 in the first locked state. When the torque tube 1 swings along the second swing direction to the second lower preset angle α2, the second lower stop area 82 is in contact with the pointed head on the lock head to put the torque tube 1 in the first locked state.

[0032] In some alternative embodiments, the arc-shaped plate 8 is integrally formed with the shell 2 or formed separately. For example, the arc-shaped plate 8 and the shell 2 are integrally cast, or the arc-shaped plate 8 is an independent structure that is fixedly connected to the shell 2 by bolts.

[0033] In some alternative embodiments, the locking member 9 is mounted below the torque tube 1 via a locking member mounting member.

[0034] As an optional solution, the locking component mounting component includes a screw 71, a screw end, and a first mounting part 73. The locking component 9 is mounted below the torque tube 1 via the screw 71. The screw 71 passes through the torque tube 1 so that the screw end extends out of the torque tube 1. The locking component 9 is provided with a second mounting part 92 that cooperates with the screw end for mounting the locking component 9.

[0035] As an optional solution, a suspension part 23 is provided on the top of the housing 2, and the torque tube 1 is suspended on the housing 2 through the first mounting part 73 and the suspension part 23.

[0036] The first mounting part 73 is specifically configured as a screw head with a through hole, and the corresponding suspension part 23 is provided with a through hole. The first mounting part 73 and the suspension part 23 are connected by the first fastener 72, so that the locking member mounting part rotates on the suspension part 23 of the housing 2.

[0037] Furthermore, the screw 71 passes through the torque tube 1 so that the screw head extends out of the torque tube 1. More specifically, a washer is provided at the connection between the torque tube 1 and the outer contour of the screw 71, and a nut is used to lock the screw at the end, so that the torque tube 1 is suspended from the housing 2.

[0038] Specifically, such as Figure 8 As shown, the lock head is specifically composed of a pointed head 91 and a second mounting part 92. The pointed head 91 and the second mounting part 92 are integrally formed. The second mounting part 92 is set as a pair of ear plates. Both the ear plates and the screw end are provided with through holes. The second mounting part 92 and the screw end are connected by a second fastener, so that the locking member 9 rotates below the torque tube 1.

[0039] In some alternative embodiments, the cross-section of the torque tube 1 is set to be circular, rectangular, hexagonal, octagonal, D-shaped, or square.

[0040] Correspondingly, the outline of the upper stop region 25 is the same as the outline of the torque tube 1 when it rotates to that position. That is, part of the outer outline of the torque tube 1 can fit with the upper stop region 25 in the second locking state. For example, when the cross-section of the torque tube 1 is set to a circle, the outline of the upper stop region 25 is set to an arc shape.

[0041] In some alternative embodiments, the housing 2 is further provided with a reversing part 26, which is used to guide the locking member 9 and change the tilt direction of the locking member 9.

[0042] The reversing part 26 is configured as a block-shaped structure on the housing 2 located at the end of the arc plate 8 and protruding relative to the arc plate 8. The reversing part 26 is used to guide the locking member 9 when it rotates and change the tilt direction of the locking member 9, such as adjusting it from tilting to the left to tilting to the right or from tilting to the right to tilting to the left. When the locking member 9 is in the area outside the arc plate 8 and does not contact the housing 2, the locking member 9 is in a vertical state under the action of gravity. When the locking member 9 contacts the reversing part 26, the locking member 9 is in a tilted state.

[0043] A photovoltaic tracking bracket includes the aforementioned limiting mechanism for the tracking bracket, and further includes a driving component 10, a driving column 4, a first non-driving column 5, a second non-driving column 6, and a column adapter 51. The first non-driving column 5 and the second non-driving column 6 are arranged adjacent to each other in sequence. For example, counting from the end of a single row of tracking brackets, odd-numbered columns are the first non-driving columns 5, and even-numbered columns are the second non-driving columns 6. The driving component 10 is installed on the top of the driving column 4 and is fixedly connected to the torque tube 1 via a crank 3. The driving component 10 is preferably a worm gear reducer. The housing 2 is fixedly installed on the first non-driving column 5 or the second non-driving column 6 via the column adapter 51.

[0044] like Figure 9 , Figure 10 As shown, in some optional embodiments, the housing 2 includes a first housing 21 installed on the first non-drive column 5 and a second housing 22 installed on the second non-drive column 6. The fracture openings 24 on the first housing 21 and the second housing 22 face the same direction, so that the photovoltaic cables of multiple photovoltaic modules can be directly attached to the end of the torque tube 1 near the fracture opening 24 for arrangement, reducing the waste caused by the winding of photovoltaic cables and thus reducing the cost of photovoltaic cables.

[0045] When the torque tube 1 swings along the first swing direction to an upper preset angle β1, the upper stop area 25 is used to cooperate with the locking member 9 to lock the torque tube 1. When the torque tube 1 swings along the second swing direction, it can pass through the fracture opening 24. One of the first swing direction and the second swing direction is clockwise and the other is counterclockwise.

[0046] like Figure 11 , Figure 12As shown, the housing 2 includes a first housing 21 installed on the first non-drive column 5 and a second housing 22 installed on the second non-drive column 6. The fracture openings 24 on the first housing and the second housing face opposite directions, so that when the left side is limited at a large angle, the first housing 21 with the opening to the right is used for limiting, and when the right side is limited at a large angle, the first housing 22 with the opening to the left is used for limiting.

[0047] like Figure 7 As shown, taking the normal tracking of the sun's rotation during the day as an example, in the early morning, the photovoltaic modules installed on the tracking bracket face the direction of the rising sun in the east, and in the evening, the photovoltaic modules installed on the tracking bracket face the direction of the setting sun in the west. During this process, the tracking bracket rotates counterclockwise from west to east. During the daytime sun tracking process, the torque tube 1 is always in the open state, and the locking member 9 moves from the upper left through the first lower stop area 81 and the second lower stop area 82 to the upper right upper stop area 25. During this process, the locking member 9 exhibits different postures, as detailed below: In the morning, the locking member 9 is located on the upper left of the arc plate 8 and is in a vertical state under the action of gravity. As the sun rises, the locking member 9 rotates counterclockwise toward the reversing part 26 on the left side and begins to tilt to the left after its bottom contacts the reversing part 26 on the left side. After passing the first lower stop area 81, it enters the arc plate 8 and slides across the arc plate 8 in a state of tilting to the left. When passing the second lower stop area 82, the pointed head 91 on the locking member 9 does not lock with the second lower stop area 82, and the locking member 9 can smoothly pass through the second lower stop area 82. After disengaging from the reversing part 26 on the right side, the locking member 9 is in a vertical state under the action of gravity until the sun sets in the evening. Finally, it locks at the upper stop area 25 to complete the daytime tracking process. Therefore, it can be seen that the locking member 9 is always in a passable state when tracking the sun normally during the day.

[0048] Similarly, during the night return process, when the tracking bracket rotates back to face the photovoltaic module eastward, the locking component 9 remains in a passable state during the rotation. This demonstrates that the locking component 9 and the arc plate 8 do not affect the normal operation of the tracking bracket.

[0049] When strong winds occur, when the locking element 9 is located between the first lower stop area 81 and the second lower stop area 82 on the arc plate 8, or is located outside the arc plate 8 but near the reversing part 26, the rotation direction of the tracking bracket is controlled according to the position of the locking element 9, as follows: When the locking member 9 is between the first lower stop area 81 and the second lower stop area 82 on the arc plate 8, if the locking member 9 is tilted to the left (i.e., during normal daytime tracking), the torque tube 1 is controlled to rotate clockwise instead of counterclockwise, so that the pointed head on the locking member 9 is in contact with the first lower stop area 81, thereby limiting the torque tube 1 and preventing it from rotating further; if the locking member 9 is tilted to the right (i.e., during nighttime return), the torque tube 1 is controlled to rotate counterclockwise instead of clockwise, so that the pointed head 91 on the locking member 9 is in contact with the second lower stop area 82, thus limiting the torque tube 1. When the locking member 9 is located outside the arc plate 8 but near the reversing part 26, if the locking member 9 is in the upper left position of the arc plate 8, the torque tube 1 is adjusted to enter the first lower stop area 81 and the second lower stop area 82 counterclockwise and then rotated clockwise in the opposite direction so that the locking member 9 abuts against the first lower stop area 81; similarly, when the locking member 9 is in the upper right position of the arc plate 8, the torque tube 1 is adjusted to enter the first lower stop area 81 and the second lower stop area 82 clockwise and then rotated counterclockwise in the opposite direction so that the locking member 9 abuts against the second lower stop area 82.

[0050] In addition, at night, the torque tube 1 can be positioned between the first lower stop area 81 and the second lower stop area 82 on the arc plate 8, such as near 0° when the tracking bracket is flat. This reduces the rotation angle required for the torque tube 1 to rotate to the first lower stop area 81 or the second lower stop area 82, thereby quickly achieving locking protection.

[0051] The locking mechanism described above allows the tracking bracket to remain open during normal operation. When strong winds occur, it rotates in the opposite direction to enter the locking state, thereby locking the torque tube 1 to a safe position. This provides wind protection for the entire tracking bracket and improves its wind resistance.

[0052] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
