Description

Technical Field

[0001] This invention relates to the field of tracker equipment technology, and more particularly to a housing, locking mechanism, housing assembly, and photovoltaic system for a photovoltaic system. Background Technology

[0002] The main challenge currently facing photovoltaic (PV) tracking systems lies in their operational stability under wind loads. Especially under high wind protection conditions, the larger area of ​​the PV modules significantly increases the wind load that the bearing housings must withstand, placing more stringent demands on structural stability, as detailed below: Firstly, regarding sudden strong winds, although some manufacturers have implemented corresponding wind protection strategies, choosing to stop at a small angle (i.e., when the photovoltaic modules are nearly level) to reduce wind load or at a large angle (i.e., at the extreme angle of the tracking bracket's rotation) to provide more locking points, the timing of the approaching strong wind is difficult to predict, resulting in a longer response time to rotate to the small or large angle. If the bracket cannot reach the designated protection position in time, it can easily damage the bracket structure. Secondly, for photovoltaic systems with suspended structures, the resistance during rotation is lower, making the bracket structure more susceptible to wind movement in a suspended state. Thirdly, existing technologies employ multi-point electrical drives to rotate the tracking bracket, using the one-way 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 unsuitable for large-scale adoption. Therefore, it is necessary to provide designated protection positions for different operating conditions to improve adaptability, while also reducing the time it takes for the photovoltaic tracking bracket to reach the designated protection position. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a housing for a photovoltaic system, which can cooperate with a locking mechanism to limit the torque tube suspended therein within a smaller preset angle range, thereby improving adaptability to different operating conditions.

[0004] The present invention also provides a locking mechanism that cooperates with the housing of a photovoltaic system.

[0005] The present invention also provides a housing assembly for a photovoltaic system.

[0006] The present invention also provides a photovoltaic system with a housing that is compatible with a photovoltaic system.

[0007] According to a first aspect of the photovoltaic system housing, the housing has an opening that can cooperate with a locking mechanism to limit the torque tube suspended through the opening. The housing includes a body portion, the body portion having a suspension portion, and the body portion extending in a circumferential direction and defining the opening. A stop portion is disposed on the body portion, the stop portion having a first lower stop region and a second lower stop region. When the torque tube swings along a first swing direction to a first lower preset angle α1, the first lower stop region can be used to cooperate with the locking mechanism to keep the torque tube in a position... In the locked state, when the torque tube swings along the second swing direction to the second lower preset angle α2, the second lower stop area can be used to cooperate with the locking mechanism to put the torque tube in the locked state. One of the first swing direction and the second swing direction is clockwise and the other is counterclockwise. When the torque tube is in the locked state, the stop part is disengaged from the locking mechanism by swinging the torque tube in the opposite direction to put the torque tube into the passage state. Both the first lower preset angle α1 and the second lower preset angle α1 are not greater than 45°.

[0008] According to an embodiment of the photovoltaic system of the present invention, the housing is configured with a stop portion having a first lower stop region and a second lower stop region. The first lower stop region engages with a locking mechanism when the torque tube swings a first lower preset angle α1, and the second lower stop region engages with the locking mechanism when the torque tube swings a second lower preset angle α2. This locks the torque tube at the first lower preset angle α1 and the second lower preset angle α2. When the torque tube is in the locked state, the stop portion can disengage from the locking mechanism by reversing the swing, thereby allowing the torque tube to transition from the locked state to the passable state. This achieves the switching between locking and passable states of the torque tube, and the structure is simple, allowing for limiting and adjusting the torque tube at relatively small preset angles, thus improving adaptability.

[0025] According to some embodiments of the present invention, the first lower preset angle α1 has a value range of 0° < α1 ≤ 30°, and the second lower preset angle α2 has a value range of 0° < α2 ≤ 30°.

[0026] According to some embodiments of the present invention, the torque tube can swing from a first upper preset angle β1 to a second upper preset angle β2. The body includes a first upper stop region and a second upper stop region. The first upper stop region is higher than the first lower stop region in the vertical direction, and the second upper stop region is higher than the second lower stop region in the vertical direction. When the torque tube swings around the suspension portion to the first upper preset angle β1, the first upper stop region abuts against the torque tube to act as a fourth stop. When the torque tube swings around the suspension portion to the second upper preset angle β2, the second upper stop region abuts against the torque tube to act as a fifth stop. The first upper preset angle β1 > the first lower preset angle α1, and the second upper preset angle β2 > the second lower preset angle α2.

[0027] According to a second aspect of the present invention, a locking mechanism for a photovoltaic system is capable of cooperating with the housing of the photovoltaic system to limit the torque tube suspended through the housing. The locking mechanism includes a locking support member adapted to be suspended in the suspension portion of the housing; and a locking member having a pivot portion, the locking member being pivotally connected to the locking support member via the pivot portion.

The first lower preset angle α1 and the second lower preset angle α1 are both no greater than 45°.

[0028] According to an embodiment of the photovoltaic system of the present invention, the locking mechanism connects the locking support member to the suspension portion of the housing of the first aspect embodiment of the present invention, thereby causing the torque tube to swing. The locking member is pivotally connected to the locking support member, and the locking member is structured to have a first locking surface and a second locking surface. The first locking surface engages with the stop portion of the housing of the first aspect embodiment of the present invention to lock the torque tube at a first lower preset angle α1, and the second locking surface engages with the stop portion of the housing of the first aspect embodiment of the present invention to lock the torque tube at a second lower preset angle α2. This achieves locking of the torque tube at the first lower preset angle α1 and the second lower preset angle α2. When the torque tube is in the locked state, the locking member can disengage from the stop portion of the housing by swinging in the opposite direction, thereby allowing the torque tube to transition from the locked state to the passage state.

[0038] According to some examples of the present invention, the bending surface includes a first fold and a second fold, wherein the length of the first fold on the cross-section of the locking member is greater than the length of the second fold on the cross-section of the locking member.

[0039] According to some embodiments of the present invention, the locking support member includes: a pin head for pivotally connecting to the suspension portion of the housing; a fixing portion, one end of which is connected to the pin head and the other end of which is connected to the pivot portion, adapted to fix the torque tube; and a locking member mounting member, which is disposed at the other end of the fixing portion, and the locking member is connected to the locking member mounting member through the pivot portion.

When the torque tube swings to the first lower preset angle α1 or the second lower preset angle α2, the locking surface and the lower stop area make contact and form a fitting structure to lock the torque tube. The line connecting the suspension portion, the pivot portion, and the fitting structure between the projections of the opening onto the plane satisfies: c < a + b, where the line connecting the fitting structure and the pivot portion is a, the line connecting the pivot portion and the suspension portion is b, and the line connecting the suspension portion and the fitting structure is c.

Detailed Implementation

[0081] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0082] The following description, with reference to the accompanying drawings, describes a housing 100 of a photovoltaic system according to a first aspect of the present invention, which is capable of cooperating with a locking mechanism 200 according to a second aspect of the present invention to limit the torque tube 500 in the photovoltaic system.

[0083] like Figures 1 to 49 As shown, the housing 100 of the photovoltaic system according to an embodiment of the present invention includes a body portion 10 and a stop portion 20.

[0084] like Figure 1 The main body 10 is provided with a suspension part 11. The torque tube 500 can be suspended and connected to the main body 10 through the suspension part 11. It should be noted that the torque tube 500 can be directly connected to the main body 10 through the suspension part 11 or indirectly connected to the main body 10 through the suspension part 11.

[0085] The main body 10 extends circumferentially and forms an opening 12 through which the torque tube 500 passes, such as... Figures 1-3 As shown, the body portion 10 can be formed into a closed ring structure, such as... Figure 4 As shown, it can also be formed as an open ring structure. The stop portion 20 is connected to the body portion 10. For example, the stop portion 20 can be integrally formed with the body portion 10, or it can be detachably provided in the stop portion 20. The stop portion 20 has a first lower stop region 215 and a second lower stop region 225. The first lower stop region 215 is configured to lock the torque tube 500 that swings along the first swing direction, and the second lower stop region is configured to lock the torque tube 500 that swings along the first swing direction. like Figure 14 , Figure 26 When the torque tube 500 swings along the first swing direction to the first lower preset angle α1, the first lower stop region 215 can cooperate with the locking mechanism 200 to put the torque tube 500 in a locked state, such as... Figure 16 , Figure 28 When the torque tube 500 swings along the second swing direction to the second lower preset angle α2, the second lower stop region 225 can cooperate with the locking mechanism 200 to lock the torque tube 500. The first swing direction and the second swing direction are opposite, and, as Figure 14 , 16The first preset angle and the second preset angle are the swing angles formed by the torque tube 500 in the locked position and the free-hanging state. The first preset angle α1 ≤ 45° and the second preset angle α2 ≤ 45°, thereby realizing the rapid locking of the torque tube 500 within a small angle range. For example, in some specific embodiments, α1 ≤ 30° or α1 ≤ 15°, α2 ≤ 30° or α2 ≤ 15°, thereby achieving rapid locking of the torque tube 500 at a smaller angle within a smaller response time.

[0086] Furthermore, when the torque tube 500 is in the locked state, the stop part 20 is disengaged from the locking mechanism 200 by reversing the torque tube 500, thereby allowing the torque tube 500 to enter the open state. For example, as shown... Figure 14 In the locked state shown in the figure, the first swing direction is counterclockwise. At this time, the torque tube 500 can be swung in the opposite direction, that is, swung along the second swing direction, so as to realize the stop part 20 and the locking mechanism 200 disengage, thereby allowing the torque tube 500 to quickly enter the passage state.

[0087] Therefore, the housing 100 of the photovoltaic system according to an embodiment of the present invention, by configuring the stop portion 20 to have a first lower stop region 215 and a second lower stop region 225, utilizes the first lower stop region 215 to engage with the locking mechanism 200 when the torque tube 500 swings at a first lower preset angle α1, and the second lower stop region 225 to engage with the locking mechanism 200 when the torque tube 500 swings at a second lower preset angle α2, thereby locking the torque tube 500 at the first lower preset angle α1 and the second lower preset angle α2. When the torque tube 500 is in the locked state, the stop portion 20 can be disengaged from the locking mechanism 200 by swinging in the opposite direction, thereby enabling the torque tube 500 to enter the passage state from the locked state. This achieves rapid locking and passage switching of the torque tube 500, and has a simple structure, allowing for limiting and adjusting the torque tube 500 at a relatively small preset angle, thus improving adaptability.

[0088] like Figure 1-2 , Figure 4-5 , Figure 22 In some embodiments of the present invention, the stop portion 20 includes a first stop member 21 and a second stop member 22. The first stop member 21 is disposed at one end of the body portion 10 away from the suspension portion 11, and the second stop member 22 is disposed at the other end of the body portion 10 away from the suspension portion 11. A first lower stop region 215 is formed on the first stop member 21, and a second lower stop region 225 is formed on the second stop member 22. Thus, by providing the first stop member 21 and the second stop member 22, which can cooperate with the locking mechanism 200, at both ends of the body portion 10, rapid locking of the torque tube 500 in two swing directions can be achieved, thereby performing small-angle locking and reducing response time.

[0089] like Figure 1-2 , Figure 22 In some examples, the first stop 21 and the second stop 22 are arranged spaced apart along the circumferential direction of the body portion 10, and the first stop 21 and the second stop 22 are arranged opposite to each other, thereby enabling small-angle locking of the torque tube 500 in two directions.

[0090] like Figure 4-5 In some examples, the first stop 21 and the second stop 22 are spaced apart along the circumferential direction of the body portion 10, and the first stop 21 and the second stop 22 are offset from each other in the thickness direction of the body portion 10, such as... Figure 4 The thickness direction refers to the normal direction to the plane containing the opening 12, thus making it suitable for cooperation with the locking mechanism 200 of this embodiment of the invention, for example... Figure 8-9 The locking mechanism 200 shown in the figure enables small-angle locking of the torque tube 500 in two directions.

[0091] like Figure 1-2 , Figure 4-5 and Figure 22 As shown, in some examples of the present invention, the first stop 21 protrudes from the inner peripheral side of the body portion 10 and extends obliquely toward the opening 12 in a first direction, and the second stop 22 protrudes from the inner peripheral side of the body portion 10 and extends obliquely toward the opening 12 in a second direction. The projection of the extension line of the first direction onto the plane where the opening 12 is located intersects the projection of the extension line of the second direction onto the plane where the opening 12 is located.

[0092] In some examples of the present invention, the body portion 10 includes an arcuate member 16, such as... Figure 1-3 , Figure 5 When the main body 10 is a closed annular structure, the arc portion between the first stop 21 and the second stop 22 is an arc-shaped member 16, thereby enabling small-angle locking of the torque tube 500 in the direction of the torque tube 500, such as... Figure 4 When the main body 10 is an unclosed annular structure, the main body 10 is formed into an arc-shaped member 16, the first stop member 21 protrudes from one end of the arc-shaped member 16 and the second stop member 22 protrudes from the other end of the arc-shaped member 16, thereby achieving a small-angle locking of the direction relative to the torque tube 500, further simplifying the structure of the housing 100.

[0093] like Figure 22 In some examples, the body 10 includes an arc-shaped member 16 and a locking bracket 15 connected to the arc-shaped member 16. The locking bracket 15 can be a separate structure from the body 10. A first stop member 21 protrudes from one end of the locking bracket 15 and a second stop member 22 protrudes from the other end of the locking bracket 15. Thus, the separate structure design facilitates manufacturing, installation, and maintenance.

[0094] like Figures 1-5 , Figure 13-16 In some examples of the present invention, in order to quickly reverse direction and thereby lock the torque tube 500 in different directions, the body portion 10 is provided with a first reversing groove 41 and a second reversing groove 43 recessed outward along the radial direction of the body portion 10 on the circumferential side surface of the body portion 10. The first reversing groove 41 is provided in the circumferential direction on the side of the first stop member 21 away from the second stop member 22, and the second reversing groove 43 is provided in the circumferential direction on the side of the second stop member 22 away from the first stop member 21. This cooperates with the locking mechanism 200 of the embodiment of the present invention, so that the pivoting direction of the free end 222 of the locking mechanism 200 changes, thereby realizing reversing locking.

[0095] like Figure 2 In some examples of the present invention, in order to further improve the response speed, when the first stop 21 and the second stop 22 are arranged opposite to each other, the body portion 10 is also provided with a third reversing groove 43 that is recessed outward along the radial direction of the body portion 10 on the peripheral side surface of the body portion 10. The third reversing groove 43 is provided between the first stop 21 and the second stop 22. Thus, by arranging the first reversing groove 41 and the third reversing groove 43, and the second reversing groove 43 and the third reversing groove 43, the free end 222 of the locking mechanism 200 of the embodiment of the present invention can change its pivoting direction between the first reversing groove 41 and the third reversing groove 43, and between the second reversing groove 43 and the third reversing groove 43, thereby reducing the reversing stroke, further improving the response speed, and realizing reversing locking.

[0096] like Figure 3 In other examples of the invention, the stop 20 includes a third stop 23 having a first lower stop region 215 and a second lower stop region 225 arranged opposite each other in the circumferential direction, thereby simplifying the structure by providing a single third stop 23 to lock the torque tube 500 at a small angle in two directions.

[0097] like Figure 3 Furthermore, the third stop 23 is provided below the suspension part 11. The third stop 23 protrudes inward in the body part 10 along the radial direction of the body part 10. For example, the third stop 23 is a cuboid structure.

[0098] Optionally, the body part 10 includes an arc-shaped member 16 and a locking bracket 15 connected to the arc-shaped member 16. The third stop member 23 is formed as a protrusion protruding inward from the locking bracket 15 in the radial direction of the locking bracket 15, thereby simplifying the structure and facilitating installation and maintenance.

[0099] like Figure 22In some embodiments of the present invention, the main body 10 includes a first sub-shell 13 and a second sub-shell 14, and a locking bracket 15 sandwiched between the first sub-shell 13 and the second sub-shell 14. The first sub-shell 13 and the second sub-shell 14 each have an opening 12 that extends through their thickness direction, and the first sub-shell 13 and the second sub-shell 14 are arranged spaced apart in the normal direction of the plane where the opening 12 is located. A stop portion 20 is formed in the locking bracket 15, thereby simplifying the structure and facilitating installation and maintenance.

[0100] Optionally, the lock holder 15 has an arcuate surface, and the center of the projection of the arcuate surface onto the plane containing the opening 12 is on the same side as the center of the opening 12, for example, as shown in the image. Figure 22 The locking bracket 15 is an arc-shaped plate structure, and on the plane where the opening 12 is located, the protruding direction of the arc-shaped plate is away from the opening 12.

[0101] like Figure 22 In some embodiments of the present invention, the stop portion 20 includes a first stop 21 and a second stop 22. The first stop 21 protrudes from one end of the arc-shaped surface along the side facing the opening 12, and the second stop 22 protrudes from the other end of the arc-shaped surface along the side facing the opening 12. The first stop 21 and the second stop 22 are arranged opposite to each other. A first lower stop region 215 is formed on the first stop 21, and a second lower stop region 225 is formed on the second stop 22. Thus, the split structure design facilitates the installation and maintenance of the housing 100.

[0102] In some embodiments of the present invention, the stop portion 20 includes a first stop 21 and a second stop 22. The first stop 21 protrudes from one end of the arc-shaped surface along the side facing the opening 12, and the second stop 22 protrudes from the other end of the arc-shaped surface along the side facing the opening 12. The first stop 21 and the second stop 22 are offset from each other in the thickness direction of the locking bracket 15. A first lower stop region 215 is formed in the first stop 21, and a second lower stop region 225 is formed in the second stop 22. Thus, the split structure design facilitates the installation and maintenance of the housing 100.

[0103] In some embodiments of the present invention, the stop portion 20 includes a third stop member 23, which protrudes from the arcuate surface in the radial direction. The third stop member 23 has a first lower stop region 215 and a second lower stop region 225 arranged opposite to each other in the extending direction of the arcuate surface. Thus, by providing a single third stop member 23, small-angle locking of the torque tube 500 can be achieved in two directions, simplifying the structure.

[0104] In some embodiments of the present invention, such as Figure 14 , Figure 16In order to further achieve rapid locking at small angles, the first lower preset angle α1 has a value range of 0° < α1 ≤ 30°, and the second lower preset angle α2 has a value range of 0° < α2 ≤ 30°.

[0105] In some embodiments of the present invention, such as Figures 1-5 The torque tube 500 can swing from a first upper preset angle β1 to a second upper preset angle β2. The main body 10 includes a first upper stop region 31 and a second upper stop region 32. The first upper stop region 31 is higher than the first lower stop region 215 in the vertical direction, and the second upper stop region 32 is higher than the second lower stop region 225 in the vertical direction. When the torque tube 500 swings around the suspension part 11 to the first upper preset angle β1, the first upper stop area 31 stops the torque tube 500 as a fourth stop. When the torque tube 500 swings around the suspension part 11 to the second upper preset angle β2, the second upper stop region 32 stops the torque tube 500 as a fifth stop. Wherein, the first upper preset angle β1 > the first lower preset angle α1, and the second upper preset angle β2 < the second lower preset angle α2.

[0106] Therefore, by setting the first upper stop area 31 and the second upper stop area 32, small-angle fast locking can be achieved in the first lower stop area 215 and the second lower stop area 225, while large-angle locking of the torque tube 500 can also be achieved, further improving the adaptability to different working conditions.

[0107] In some examples, such as Figures 1-5 The stop portion 20 has a first upper inner arc surface and a second upper inner arc surface adapted to fit against the outer peripheral wall of the torque tube 500. The first upper inner arc surface is formed as a first upper stop region 31, and the second upper inner arc surface is formed as a second upper stop region 32.

[0108] The locking mechanism 200 of a photovoltaic system 1000 according to a second aspect embodiment of the present invention is described below with reference to the accompanying drawings. The locking mechanism 200 is capable of cooperating with the housing 100 of the first aspect embodiment of the present invention to limit the torque tube 500 in the photovoltaic system.

[0109] like Figures 1 to 49 As shown, the locking mechanism 200 of the photovoltaic system 1000 according to an embodiment of the present invention includes a locking support member 210 and a locking member 220.

[0110] like Figures 6-10The locking support member 210 is adapted to be suspended in the suspension part 11 of the housing 100. The locking member 220 has a pivot part 221. The locking member 220 is pivotally connected to the locking support member 210 through the pivot part 221. The locking member 220 has a first locking surface 2221 and a second locking surface 2222.

[0111] like Figure 14 , Figure 26 When the torque tube 500 swings along the first swing direction to a first lower preset angle α1, the first locking surface 2221 can be used to cooperate with the housing 100 to put the torque tube 500 in a locked state, such as... Figure 16 , Figure 28 When the torque tube 500 swings along the second swing direction to the second lower preset angle α2, the second locking surface 2222 can be used to cooperate with the housing 100 to lock the torque tube 500. One of the first swing direction and the second swing direction is clockwise and the other is counterclockwise. Furthermore, as... Figure 14 , 16 The first preset angle and the second preset angle are the swing angles formed by the torque tube 500 in the locked position and the free hanging state, wherein the first preset angle α1≤45° and the second preset angle α2≤45°, thereby realizing the rapid locking of the torque tube 500 within a small angle range.

[0112] Furthermore, when the torque tube 500 is in the locked state, the locking mechanism 200 is disengaged from the stop portion 20 of the housing 100 by reversing the torque tube 500, thereby allowing the torque tube 500 to enter the open state. For example, as shown... Figure 14 In the locked state shown in the figure, the first swing direction is counterclockwise. At this time, the torque tube 500 can be swung in the opposite direction, that is, swung along the second swing direction, so as to realize the disengagement of the locking mechanism 200 from the stop part 20 of the housing 100, thereby allowing the torque tube 500 to quickly enter the passage state.

[0113] Therefore, in the photovoltaic system 1000 according to an embodiment of the present invention, the locking mechanism 200 drives the torque tube 500 to swing through the locking support member 210, and the locking member 220 is provided with a first locking surface 2221 and a second locking surface 2222. The first locking surface 2221 engages with the housing 100 when the torque tube 500 swings at a first lower preset angle α1, and the second locking surface 2222 engages with the housing 100 when the torque tube 500 swings at a second lower preset angle α2. Thus, the torque tube 500 is locked at the first lower preset angle α1 and the second lower preset angle α2. When the torque tube 500 is in the locked state, the stop part 20 can disengage from the locking mechanism 200 by swinging in the opposite direction, thereby allowing the torque tube 500 to enter the passage state from the locked state. This achieves rapid locking and passage switching of the torque tube 500, and the structure is simple, allowing for limiting and adjusting the torque tube 500 at relatively small preset angles, thus improving adaptability.

[0114] In some embodiments of the present invention, such as Figure 14 When the first locking surface 2221 engages with the first lower stop region 215 of the housing 100 to lock the torque tube 500, a first fitting structure is formed between the first locking surface 2221 and the housing 100. On the cross-section of the locking mechanism 200, the line connecting the first fitting structure and the pivot 221 is a1, the line connecting the pivot 221 and the suspension 11 is b, and the line connecting the suspension 11 and the first fitting structure is c1, where c1 < a1 + b.

[0115] like Figure 16 When the second locking surface 2222 is used to cooperate with the housing 100 to put the torque tube 500 in a locked state, a second fitting structure is formed between the second locking surface 2222 and the housing 100. On the cross-section of the locking mechanism 200, the line connecting the second fitting structure and the pivot part 221 is a2, the line connecting the pivot part 221 and the suspension part 11 is b, and the line connecting the suspension part 11 and the second fitting structure is c2, where c2 < a2 + b.

[0116] Therefore, through the above-mentioned dimensional design, the first locking surface 2221 and the second locking surface 2222 can cooperate with the housing 100 of the present invention to achieve locking of the torque tube 500 at two angles: a first lower preset angle and a second lower preset angle.

[0117] like Figure 6 , 7 In some embodiments of the present invention, the locking member 220 is a single unit, with the first locking surface 2221 and the second locking surface 2222 respectively formed on two adjacent sides of the locking member 220. Thus, locking of the torque tube 500 in two directions can be achieved with a single locking member 220, effectively simplifying the structure.

[0118] like Figure 6 In some examples, the first locking surface 2221 and the second locking surface 2222 are integrally formed as bent surfaces that bulge outwards from the pivot portion 221, for example... Figure 6 In the middle, the first locking surface 2221 and the second locking surface 2222 are formed into a wedge-shaped structure with a cross-section that is approximately V-shaped.

[0119] like Figure 7 In some examples, the first locking surface 2221 and the second locking surface 2222 are integrally formed as bent surfaces that are concave inward toward the pivot portion 221, for example, Figure 7 In the middle, the first locking surface 2221 and the second locking surface 2222 form a bayonet structure, and the cross-section is roughly inverted V-shaped.

[0120] Preferably, the first locking surface 2221 and the second locking surface 2222 have a smooth transition, thereby reducing stress concentration on the locking surface in the locked state and improving reliability.

[0121] like Figure 8-10 In some embodiments of the present invention, the locking member 220 includes a first locking sub-member 223 and a second locking sub-member 224. The first locking sub-member 223 and the second locking sub-member 224 are pivotally connected to the other end of the locking support member 210 via a pivot portion 221. A first locking surface 2221 is formed on the first locking sub-member 223, and a second locking surface 2222 is formed on the second locking sub-member 224. Therefore, by providing locking surfaces on two independent first locking sub-members 223 and second locking sub-members 224, fatigue damage to a single locking member 220 during engagement is reduced, and reliability is improved.

[0122] like Figure 8 , 9 In some examples, the first locking element 223 and the second locking element 224 are coaxially pivoted and offset in the axial direction, thereby intersecting with the stop portion 20 in the housing 100 of the present invention (e.g., Figure 4 , Figure 5 ( ) In combination, a small-angle locking of the torque tube 500 is achieved in both swing directions.

[0123] like Figure 10 In some examples, the first locking sub-component 223 and the second locking sub-component 224 are arranged spaced apart along the outer periphery of the locking support member 210 and pivot parallel to the locking support member 210.

[0124] Furthermore, the locking support member 210 is provided with a first pivot mounting member 2123 and a second pivot mounting member 2124. The first locking sub-member 223 and the second locking sub-member 224 are connected to the first pivot mounting member 2123 and the second pivot mounting member 2124 in a one-to-one correspondence, thereby locking the torque tube 500 at a small angle in two swing directions.

[0125] like Figure 8-10 In some embodiments, in order to improve the fit between the locking member 220 and the stop portion 20 of the housing 100, both the first locking member 223 and the second locking member 224 are formed as bent surfaces that are recessed inward toward the pivot portion 221. The first locking surface 2221 is formed on the bent surface of the first locking member 223, and the second locking surface 2222 is formed on the bent surface of the second locking member 224.

[0126] Furthermore, the bending surface includes a first fold and a second fold, wherein the length of the first fold on the cross-section of the locking member 220 is greater than the length of the second fold on the cross-section of the locking member 220. When the locking support member 210 is in a free state, the first fold is positioned relative to the stop member adjacent to the second fold. This improves the effective stop-locking fit between the locking member 220 and the stop member of the housing 100.

[0127] like Figures 6-10 In some embodiments, the locking support member 210 includes a pin head 211, a fixing portion 212, and a locking member 220 mounting member 213. The pin head 211 is pivotally connected to the suspension portion 11 of the housing 100. One end of the fixing portion 212 is connected to the pin head 211, and the other end is connected to the pivot portion 221, which is suitable for fixing the torque tube 500. The locking member 220 mounting member 213 is located at the other end of the fixing portion 212, and the locking member 220 is connected to the locking member 220 mounting member 213 through the pivot portion 221. This causes the torque tube 500 to swing and the locking member 220 to pivot.

[0128] Optionally, the fixing part 212 can be a pin structure, a clamp structure, or a sleeve structure.

[0129] like Figure 6 , 8 -9. In some embodiments, when the fixing part 212 is a pin structure, the pin structure can be inserted into the torque tube 500, thereby fixing the torque tube 500 by means of the pin structure.

[0130] like Figure 7 In some embodiments, when the fixing part 212 is a clamping structure, the clamping structure includes a first clamping plate 2121, a second clamping plate 2122, and fasteners. The arc length of the first clamping plate 2121 is greater than the arc length of the second clamping plate 2122. The first clamping plate 2121 and the second clamping plate 2122 can be clamped on the outer periphery of the torque tube 500 and fastened by fasteners. Further, one of the pin head 211 and the locking member 220 mounting member 213 is provided at one end of the first clamping plate 2121, and the other of the pin head 211 and the locking member 220 mounting member 213 is provided at the other end of the first clamping plate 2121.

[0131] Therefore, the fixing reliability of the torque tube 500 can be improved by using the clamp structure.

[0132] like Figure 10 In some embodiments, when the fixing part 212 is a jacket structure, the jacket structure includes a first clamping plate 2121, a second clamping plate 2122 and fasteners, and the first clamping plate 2121 and the second clamping plate 2122 are connected by fasteners to form a ring.

[0133] Furthermore, when the fixing part 212 is a jacket structure, the jacket structure includes a first clamping plate 2121, a second clamping plate 2122, and fasteners. The first clamping plate 2121 and the second clamping plate 2122 are connected by fasteners to form a ring. Thus, the fixing reliability of the torque tube 500 can be improved by the jacket structure.

[0134] In some examples, the locking member 220 mounting member 213 includes two members, which are respectively disposed on the first clamping plate 2121 and the second clamping plate 2122, and are symmetrically arranged in the vertical direction. The arrangement of the two locking members 220 mounting members 213, along with the stop members of the housing 100 in this embodiment of the invention (such as…), Figure 3 This combination allows for small-angle locking of the torque tube 500 in both swing directions.

[0135] The housing assembly 300 of a photovoltaic system 1000 according to a third aspect of the present invention is described below with reference to the accompanying drawings. It is capable of limiting the torque tube 500 in the photovoltaic system.

[0136] like Figures 1 to 49 As shown, the housing assembly 300 of the photovoltaic system 1000 according to an embodiment of the present invention includes a housing 100 and a locking mechanism 200.

[0137] The housing 100 includes a body portion 10 and a stop portion 20. The body portion 10 is provided with a suspension portion 11. The body portion 10 extends in the circumferential direction and surrounds an opening 12 through which the torque tube 500 passes. The stop portion 20 is provided on the body portion 10. For example, the stop portion 20 can be integrally formed on the body portion 10 or separately assembled on the body portion 10. The stop portion 20 has a lower stop area.

[0138] The stop part 20 includes a locking support member 210 and a locking member 220. The locking support member 210 is connected to the suspension part 11 and is used to fix the torque tube 500 and drive the torque tube 500 to swing between at least a first lower preset angle α1 and a second lower preset angle α2. The locking member 220 has a pivot part 221 and is connected to the locking support member 210 through the pivot part 221. One end of the locking member 220 facing away from the pivot part 221 forms a free end 222 that can pivot around the pivot part 221 under its own weight. The free end 222 has a locking surface.

[0139] like Figure 14 , 16 26, 28. When the torque tube 500 swings to the first lower preset angle α1 or the second lower preset angle α2, the locking surface and the lower stop area make contact and form a fitting structure so that the torque tube 500 is in a locked state. The line connecting the suspension part 11, the pivot part 221 and the fitting structure in the plane projection of the opening 12 satisfies: c < a + b, where the line connecting the fitting structure and the pivot part 221 is a, the line connecting the pivot part 221 and the suspension part 11 is b, and the line connecting the suspension part 11 and the fitting structure is c.

[0140] For example, such as Figure 14 When the torque tube 500 swings to the first preset angle α1, the line a connecting the fitting structure and the pivot 221 is a1, and the line c connecting the suspension part 11 and the fitting structure is c1, as shown. Figure 16 When the torque tube 500 swings to the second lower preset angle α2, the line a connecting the fitting structure and the pivot part 221 is a2, and the line c connecting the suspension part 11 and the fitting structure is c2.

[0141] Therefore, in the photovoltaic system 1000 according to an embodiment of the present invention, the housing assembly 300 is configured such that the line connecting the suspension part 11, the pivot part 221, and the bonding structure projected onto the plane where the opening 12 is located is set to c < a + b. This ensures that when the torque tube 500 swings to a first lower preset angle α1 or a second lower preset angle α2, the locking surface and the lower stop region come into contact and form a bonding structure, thereby locking the torque tube 500. This achieves rapid locking of the torque tube 500, has a simple structure, and allows for limiting and adjusting the torque tube 500 at relatively small preset angles, improving adaptability.

[0142] like Figure 13-16 25-28, 38, 40-45, In some embodiments of the present invention, the free end 222 has a first pivoting direction and a second pivoting direction in the free state, the first pivoting direction and the second pivoting direction are opposite to each other, and the locking bearing member 210 has a first swinging direction and a second swinging direction in the free state, the first swinging direction and the second swinging direction are opposite to each other; When the torque tube 500 is in the locked state, the free end 222 has a pivoting tendency toward the first pivoting direction. The locking bearing 210 swings toward the first swinging direction to lock the free end 222 at the fitting structure. The first swinging direction is in the same direction as the first pivoting direction. Among the first pivoting direction and the second pivoting direction, one is clockwise and the other is counterclockwise.

[0143] like Figure 14As shown, the torque tube 500 tends to swing clockwise under the action of wind (at this time, clockwise is the first swing direction), and the locking member 220 has a pivoting tendency in the clockwise direction under the action of the locking support member 210 and the stop part 20 (at this time, clockwise is the first pivoting direction). Thus, the torque tube 500 swings towards the first swing direction to form a fitting structure between the locking member 220 and the stop part 20, thereby achieving locking.

[0144] like Figure 14 , 16 In some examples, such as 26 and 28, when the torque tube 500 is in the locked state, the locking support member 210 is swung along the second swing direction to disengage the locking surface from the lower stop area, and the torque tube 500 enters the passing state. This enables a rapid switch from the locked state to the passing state, improving response time.

[0145] like Figure 13 , 15 25, 27, in some examples, such as Figure 13 , 25 The swing direction of the locking support member 210 is clockwise, that is, the first swing direction is clockwise. The free end 222 of the locking member 220 has a counterclockwise pivoting tendency. For example, under the action of the locking bracket 15 of the body part 10 or under the action of the stop part 20, the other degree of freedom of the free end 222 is restricted, that is, the first pivoting direction is counterclockwise. Or, as Figure 15 , 27 The swing direction of the locking support member 210 is counterclockwise, that is, the second swing direction is counterclockwise. The free end 222 of the locking member 220 has a counterclockwise pivoting tendency. For example, under the action of the locking bracket 15 of the body part 10 or under the action of the stop part 20, the other degree of freedom of the free end 222 is restricted, that is, the second pivoting direction is clockwise. At this time, the swing direction of the locking support member 210 is opposite to the pivoting tendency direction of the free end 222 of the locking member 220.

[0146] like Figure 1-5 11-46, In some embodiments of the present invention, the housing 100 further includes a reversing portion disposed adjacent to the stop portion 20. For example, the reversing portion is disposed in the body portion 10 and located below the stop portion 20 in the swing direction of the torque tube 500. When the locking member 220 passes through the reversing portion, it realizes the reversal of the pivoting tendency direction of the free end 222.

[0147] like Figure 13-16 In some embodiments of the present invention, the torque tube 500 is switched through the switching section before entering the locking state from the passing state.

[0148] Furthermore, during the reversing process of the torque tube 500, the swing direction of the locking bearing member 210 is opposite to the pivoting trend direction of the free end 222, thereby changing the pivoting trend direction of the free end 222 after the reversing, so that when the torque tube 500 swings under the action of wind, it can achieve a stop-locking engagement with the locking member 220.

[0149] like Figures 1-5 , Figure 13-16 In some examples of the present invention, in order to quickly reverse the direction and thereby lock the torque tube 500 in different directions, the body portion 10 is provided with a first reversing groove 41 and a second reversing groove 43 recessed outward along the radial direction of the body portion 10 on the circumferential side surface of the body portion 10. The first reversing groove 41 is provided in the circumferential direction on the side of the first stop member 21 away from the second stop member 22, and the second reversing groove 43 is provided in the circumferential direction on the side of the second stop member 22 away from the first stop member 21, thereby changing the pivoting tendency direction of the free end 222 and thereby achieving reversing lock.

[0150] like Figure 14 , Figure 26 In some examples of the present invention, the lower stop region includes a first lower stop region 215 and a second lower stop region 225, and the locking surface includes a first locking surface 2221 and a second locking surface 2222. When the torque tube 500 swings along the first swing direction to a first lower preset angle α1, the first locking surface 2221 can be used to cooperate with the housing 100 to put the torque tube 500 in a locked state, such as... Figure 16 , Figure 28 When the torque tube 500 swings along the second swing direction to the second lower preset angle α2, the second locking surface 2222 can be used to cooperate with the housing 100 to lock the torque tube 500. One of the first swing direction and the second swing direction is clockwise and the other is counterclockwise. Furthermore, as... Figure 14 , 16 The first preset angle and the second preset angle are the swing angles formed by the torque tube 500 in the locked position and the free hanging state, wherein the first preset angle α1≤45° and the second preset angle α2≤45°, thereby realizing the rapid locking of the torque tube 500 within a small angle range.

[0151] like Figure 13-1625-28, In some examples of the present invention, the locking member 220 is a single unit, with a first locking surface 2221 and a second locking surface 2222 respectively formed on two adjacent sides of the locking member 220; the stop portion 20 includes a first stop member 21 and a second stop member 22, with a first lower stop region 215 formed on the first stop member 21 and a second lower stop region 225 formed on the second stop member 22. Thus, by having one locking member 220 cooperate with two stop members respectively, small-angle locking of the torque tube 500 can be achieved in two directions.

[0152] In some examples of the present invention, such as Figure 13-16 The first locking surface 2221 and the second locking surface 2222 are integrally formed as bent surfaces that bulge outwards from the pivot portion 221, for example, Figure 13 In the middle, the first locking surface 2221 and the second locking surface 2222 are formed into a wedge-shaped structure, with a cross-section that is approximately V-shaped, such as... Figure 25-28 The first locking surface 2221 and the second locking surface 2222 are integrally formed as bent surfaces that are concave inward toward the pivot portion 221, for example, Figure 7 In the middle, the first locking surface 2221 and the second locking surface 2222 form a bayonet structure, and the cross-section is roughly inverted V-shaped.

[0153] like Figures 42-46 In some embodiments of the present invention, there are two locking members 220, namely a first locking sub-member 223 and a second locking sub-member 224. A first locking surface 2221 is formed on the first locking sub-member 223 and a second locking surface 2222 is formed on the second locking sub-member 224. The stop part 20 is a third stop member 23. The third stop member 23 has a first lower stop region 215 and a second lower stop region 225 arranged opposite to each other in the circumferential direction. Thus, by setting a single third stop member 23, the torque tube 500 can be locked at a small angle in two directions, simplifying the structure.

[0154] like Figure 3 Furthermore, the third stop 23 is provided below the suspension part 11. The third stop 23 protrudes inward in the body part 10 along the radial direction of the body part 10. For example, the third stop 23 is a cuboid structure.

[0155] Optionally, the stop 20 includes a third stop 23, which has a first lower stop region 215 and a second lower stop region 225 arranged opposite to each other in the circumferential direction. Thus, by providing a single third stop 23, the torque tube 500 can be locked at a small angle in two directions, simplifying the structure.

[0156] like Figure 43Furthermore, the third stop 23 is provided below the suspension part 11. The third stop 23 protrudes inward in the body part 10 along the radial direction of the body part 10. For example, the third stop 23 is a cuboid structure.

[0157] Optionally, the third stop 23 protrudes inwardly from the body portion 10 along the radial direction, and the first locking sub-part 223 and the second locking sub-part 224 are arranged spaced apart along the outer periphery of the locking support member 210 and pivot parallel to the locking support member 210, thereby simplifying the structure and facilitating installation and maintenance.

[0158] like Figure 43 In some examples, in order to achieve the locking engagement of the first locking sub-component 223 with the first lower stop region 215 and the second locking sub-component 224 with the second lower stop region 225, the distance between the pivot axis of the first locking sub-component 223 and the pivot axis of the second locking sub-component 224 is greater than the distance between the first lower stop region 215 and the second lower stop region 225.

[0159] like Figure 37-41 In some embodiments of the present invention, there are two locking members 220, namely a first locking sub-member 223 and a second locking sub-member 224. A first locking surface 2221 is formed on the first locking sub-member 223, and a second locking surface 2222 is formed on the second locking sub-member 224. The stop part 20 includes a first stop member 21 and a second stop member 22. A first lower stop region 215 is formed on the first stop member 21, and a second lower stop region 225 is formed on the second stop member 22. Thus, by having two locking members 220 and two stop members cooperate one-to-one, the torque tube 500 is locked in two swing directions, effectively reducing stress damage to a single component and improving reliability.

[0160] like Figure 37-41 In some embodiments of the present invention, the first locking member 223 and the second locking member 224 are coaxially pivoted and staggered in the axial direction, and the first stop member 21 and the second stop member 22 are spaced apart in the circumferential direction of the body portion 10. The first stop member 21 and the first locking member 223 are correspondingly provided, and the second stop member 22 and the second locking member 224 are correspondingly provided.

[0161] In some examples of the present invention, such as Figure 37-41 The first locking surface 2221 and the second locking surface 2222 are integrally formed as bent surfaces protruding outward from the pivot portion 221. For example, the first locking surface 2221 and the second locking surface 2222 are formed as wedge-shaped structures with a cross-section that is approximately V-shaped. Figure 37-41The first locking surface 2221 and the second locking surface 2222 are integrally formed as bent surfaces that are recessed inward toward the pivot portion 221. For example, the first locking surface 2221 and the second locking surface 2222 are formed as a bayonet structure with a cross-section that is approximately inverted V-shaped.

[0162] like Figure 8-10 In some embodiments, in order to improve the fit between the locking member 220 and the stop portion 20 of the housing 100, both the first locking member 223 and the second locking member 224 are formed as bent surfaces that are recessed inward toward the pivot portion 221. The first locking surface 2221 is formed on the bent surface of the first locking member 223, and the second locking surface 2222 is formed on the bent surface of the second locking member 224.

[0163] Furthermore, the bending surface includes a first fold and a second fold, wherein the length of the first fold on the cross-section of the locking member 220 is greater than the length of the second fold on the cross-section of the locking member 220. When the locking support member 210 is in a free state, the first fold is positioned relative to the stop member adjacent to the second fold. This improves the effective stop-locking fit between the locking member 220 and the stop member of the housing 100.

[0164] In some examples of the present invention, the body portion 10 includes an arcuate member 16, such as... Figure 1-3 , Figure 5 When the main body 10 is a closed annular structure, the arc portion between the first stop 21 and the second stop 22 is an arc-shaped member 16, thereby enabling small-angle locking of the torque tube 500 in the direction of the torque tube 500, such as... Figure 4 When the main body 10 is an unclosed annular structure, the main body 10 is formed into an arc-shaped member 16, the first stop member 21 protrudes from one end of the arc-shaped member 16 and the second stop member 22 protrudes from the other end of the arc-shaped member 16, thereby achieving a small-angle locking of the direction relative to the torque tube 500, further simplifying the structure of the housing 100.

[0165] like Figure 22 In some examples, the body 10 includes an arc-shaped member 16 and a locking bracket 15 connected to the arc-shaped member 16. The locking bracket 15 can be a separate structure from the body 10. A first stop member 21 protrudes from one end of the locking bracket 15 and a second stop member 22 protrudes from the other end of the locking bracket 15. Thus, the separate structure design facilitates manufacturing, installation, and maintenance.

[0166] like Figure 14 , 1626, 28. When the torque tube 500 swings to the first lower preset angle α1 or the second lower preset angle α2, the locking surface and the lower stop area make contact and form a fitting structure so that the torque tube 500 is in a locked state. The line connecting the suspension part 11, the pivot part 221 and the fitting structure in the plane projection of the opening 12 satisfies: c < a + b, where the line connecting the fitting structure and the pivot part 221 is a, the line connecting the pivot part 221 and the suspension part 11 is b, and the line connecting the suspension part 11 and the fitting structure is c.

[0167] For example, such as Figure 14 When the torque tube 500 swings to the first preset angle α1, the line a connecting the fitting structure and the pivot 221 is a1, and the line c connecting the suspension part 11 and the fitting structure is c1, as shown. Figure 16 When the torque tube 500 swings to the second lower preset angle α2, the line a connecting the fitting structure and the pivot part 221 is a2, and the line c connecting the suspension part 11 and the fitting structure is c2.

[0168] like Figure 22 In some embodiments of the present invention, the main body 10 includes a first sub-shell 13 and a second sub-shell 14, and a locking bracket 15 sandwiched between the first sub-shell 13 and the second sub-shell 14. The first sub-shell 13 and the second sub-shell 14 each have an opening 12 that extends through their thickness direction, and the first sub-shell 13 and the second sub-shell 14 are arranged spaced apart in the normal direction of the plane where the opening 12 is located. A stop portion 20 is formed in the locking bracket 15, thereby simplifying the structure and facilitating installation and maintenance.

[0169] In some embodiments of the present invention, such as Figures 1-5 11-46, the torque tube 500 can swing from a first upper preset angle β1 to a second upper preset angle β2. The main body 10 includes a first upper stop region 31 and a second upper stop region 32. The first upper stop region 31 is higher than the first lower stop region 215 in the vertical direction, and the second upper stop region 32 is higher than the second lower stop region 225 in the vertical direction. When the torque tube 500 swings around the suspension part 11 to the first upper preset angle β1, the first upper stop area 31 stops the torque tube 500 as a fourth stop. When the torque tube 500 swings around the suspension part 11 to the second upper preset angle β2, the second upper stop region 32 stops the torque tube 500 as a fifth stop. Wherein, the first upper preset angle β1 > the first lower preset angle α1, and the second upper preset angle β2 < the second lower preset angle α2.

[0170] Therefore, by setting the first upper stop area 31 and the second upper stop area 32, small-angle fast locking can be achieved in the first lower stop area 215 and the second lower stop area 225, while large-angle locking of the torque tube 500 can also be achieved, further improving the adaptability to different working conditions.

[0171] In some examples, such as Figures 1-5 The stop portion 20 has a first upper inner arc surface and a second upper inner arc surface adapted to fit against the outer peripheral wall of the torque tube 500. The first upper inner arc surface is formed as a first upper stop region 31, and the second upper inner arc surface is formed as a second upper stop region 32.

[0172] like Figures 6-10 In some embodiments, the locking support member 210 includes a pin head 211, a fixing portion 212, and a locking member 220 mounting member 213. The pin head 211 is pivotally connected to the suspension portion 11 of the housing 100. One end of the fixing portion 212 is connected to the pin head 211, and the other end is connected to the pivot portion 221, which is suitable for fixing the torque tube 500. The locking member 220 mounting member 213 is located at the other end of the fixing portion 212, and the locking member 220 is connected to the locking member 220 mounting member 213 through the pivot portion 221. This causes the torque tube 500 to swing and the locking member 220 to pivot.

[0173] A photovoltaic system 1000 according to a fourth aspect of the present invention will now be described with reference to the accompanying drawings.

[0174] like Figure 1-50 According to an embodiment of the present invention, a photovoltaic system 1000 includes a column 400, a housing assembly 300 according to a third aspect of the present invention, and a torque tube 500. The housing assembly 300 is disposed on the column 400; the torque tube 500 is disposed on a locking support member 210 and passes through an opening 12, and the torque tube 500 is configured to oscillate at least between a first lower preset angle α1 and a second lower preset angle α2.

[0175] Therefore, the photovoltaic system 1000 according to the present invention uses the housing component 300 of the present invention to achieve rapid locking of the torque tube 500, and has a simple structure that can limit the adjustment of the torque tube 500 at a relatively small preset angle, thereby improving adaptability.

[0176] In some embodiments of the present invention, the range of the first preset angle α1 is 0° < α1 ≤ 30°, and the range of the second preset angle α2 is 0° < α2 ≤ 30°.

[0177] like Figures 47-50In some embodiments of the present invention, the photovoltaic system 1000 includes a drive component 600, which is connected to the torque tube 500 to drive the torque tube 500 to rotate, so as to realize the switching of the state of the torque tube 500 under different wind conditions.

[0178] like Figures 49-50 In some embodiments of the present invention, the drive assembly 600 is a push rod 610 arm, one end of which is mounted on the column 400 and the other end is connected to the torque tube 500.
