TECHNICAL FIELD

[0001] The present application relates to the technical field of support accessory, in particular to a hoop device, a support structure and a photovoltaic device. BACKGROUND

[0002] Currently, a support structure such as a photovoltaic support can be installed on a support surface such as the ground or a roof for supporting photovoltaic panels.

[0003] In the related art, a support structure mainly includes a first component (such as a column), a second component (such as a beam), and a bolt fastener. The beam is generally vertically attached to one side of the column, and then the bolt fastener is connected to the bolt hole of the column and the bolt hole of the beam.

[0004] However, in this way of fixing the beam to the outside of the edge of the column through a bolt, the centroid line of the beam is far away from the centroid point of the main section of the column, thus exerting a torsional disadvantageous stress on the column, which is not conducive to the structural stability of the column and the entire support structure. CONTENT OF THE INVENTION

[0005] One or more embodiments of the present application aim to solve or at least partially alleviate at least one of the problems in the related art.

[0006] One or more embodiments of the present application provide a hoop device, including a hoop body configured to be clamped to a first component of a support structure through a clamping portion, at least one side of the hoop body further including a bent portion extending outwardly in a direction away from the first component, the extension direction of the bent portion being perpendicular to the axis of the first component; and a fastening structure including a first fastener for connecting and fixing a second component of the support structure with the bent portion.

[0007] Compared with the related art, one or more embodiments of the present application include the following technical effects:

[0008] The hoop device can connect and fix a first component of the support structure with at least one second component, and can make the centroid line of the second component collinear with the cross-sectional centroid of the second component, thereby reducing the torsional force exerted by the second component on the first component, and improving the stability of the entire support structure. Specifically, when the hoop device fixes the support structure, the hoop body can be first tightly held on the first component, wherein the hoop body can be tightly held on the first component by the abutting part on each side, and at least one side of the hoop body includes a bending part extending outwardly away from the first component. In this way, the bending part can be inserted into the end of the second component, and the second component and the bending part are connected and fixed by the first fastener, so as to realize the connection and fixation of the first component and the at least one second component. Wherein, the bending part can be located at the middle position of the side where the hoop body is located, and since the extension direction of the bending part is perpendicular to the axis of the first component, the end of the second component connected thereto can be guaranteed to face the middle part of the corresponding side wall of the first component, that is, the centroid line of the second component is collinear with the cross-sectional centroid of the second component, and finally the stability of the entire support structure is improved.

[0009] In addition, one or more embodiments of the present application provide a support structure comprising a first component, a second component and a hoop device as described above.

A second fastener 22 can then be inserted through the first a connecting hole 241 of the two locking blocks 24 and the first b connecting hole 311 of the first component 31. After the clamp body 1 is clamped to the first component 31, the second fastener 22 can further lock the relative position between the clamp body 1 and the first component 31, resulting in a more stable overall connection. Then, the bent portions 12 on the left and right sides are inserted into the ends of the corresponding second components 32, and the second components 32 are connected and fixed to the corresponding bent portions 12 using the first fastener 21.

When connecting one first member 31 and three second members 32 through the hoop device, the first hoop 1a and the second hoop 1b can be placed on the opposite sides of the first member 31 at a suitable height of the first member 31 respectively; then the two bending edge buckles 13 at one end are clamped together through a clamping block 24, and then the limiting piece 25 is abutted on the two protruding portions 14 away from the first member 31, after that, the second fastener 22 can pass through the first a connecting hole 241 of the clamping block 24, the first b connecting hole 311 of the first member 31 and the first c connecting hole 2511 of the limiting piece 25, so as to realize the hoop body 1 being tightly held on the first member 31, and the second fastener 22 can further lock the relative position between the hoop body 1 and the first member 31, and the overall connection effect is more stable; then the integral bending portions on the left and right sides can be inserted into the end portions of the corresponding second members 32 respectively, the split bending portion on the rear side (the side of the negative direction of the X axis) is inserted into the end portion of the corresponding second member 32, and the second member 32 is connected and fixed with the corresponding bending portion 12 through the first fastener 21.

[0075] In at least one embodiment, as shown in Figure 32As shown in the fifteenth illustrated example, in the case of two split bending parts of the hoop body, that is, the first hoop 1a is provided with a first bending piece 1a1 at both ends of its extension direction, the second hoop 1b is provided with a second bending piece 1b1 at both ends of its extension direction, and the first bending piece 1a1 and the corresponding second bending piece 1b1 together constitute the split bending part; At this time, each of the first bending piece 1a1 and the corresponding second bending piece 1b1 is provided with a protruding part 14 facing each other. On this basis, the hoop device can at least connect and fix one first member 31 and at least two second members 32 through two split bending parts. Specifically, during installation, the following steps can be taken: first, place the first hoop 1a and the second hoop 1b on the opposite sides of the first member 31 respectively and at an appropriate height of the first member 31; Then abut the first limiting piece 25 at the two protruding parts 14 on one side, and then abut the second limiting piece 25 at the two protruding parts 14 on the other side; Then the second fastener 22 can be inserted through the first c connecting hole 2511 of the first limiting block 25, the first b connecting hole 311 of the one side wall of the first member 31, the first b connecting hole 311 of the other side wall of the first member 31 and the first c connecting hole 2511 of the second limiting piece 25, so as to realize the clamping of the hoop body 1 on the first member 31, and the second fastener 22 can further lock the relative position between the hoop body 1 and the first member 31, and the overall connection effect is more stable; Then, the split bending parts on both sides can be inserted into the end of the corresponding second member 32 respectively, and the second member 32 and the corresponding split bending part can be connected and fixed through the first fastener 21.

[0076] In some embodiments, as shown, Figures 6-7 As shown, the limiting piece 25 includes a limiting base plate 251 and a limiting side plate 252, the first c connecting hole 2511 is provided on the limiting base plate 251, the limiting base plate 251 is located between the first bending piece 1a1 and the second bending piece 1b1, and the limiting base plate 251 is used to abut on one side of the two protruding parts 14 away from the clamping block 24, the limiting base plate 251 is provided with the limiting side plate 252 at least one end along the length direction of the first member 31, the limiting side plate 252 is arranged at an angle with the limiting base plate 251, and the limiting side plate 252 is abutted on the corresponding end of the two protruding parts 14 along the length direction of the first member 31.

[0077] In at least one embodiment, as shown, Figures 6-7Taking the second type of clamp device as an example, the limiting base plate 251 of the limiting member 25 simultaneously abuts against the side of the two protrusions 14 away from the first member 31, and the limiting base plate 251 is provided with a first c connecting hole 2511 for the second fastener 22 to pass through. The limiting base plate 251 is located between the first bent piece 1a1 and the second bent piece 1b1. The first bent piece 1a1 and the second bent piece 1b1 can limit the middle limiting base plate 251 laterally. Secondly, the limiting member 25 also includes a limiting side plate 252 set at an angle to the limiting base plate 251. There is at least one limiting side plate 252, which simultaneously abuts against the top of the two protrusions 14. That is, the limiting member 25 overlaps the two protrusions 14 through the limiting side plate 252, which can prevent the limiting member 25 from falling off and facilitate the subsequent insertion of the second fastener 22.

[0078] The limiting side plate 252 and the limiting base plate 251 can be set at 90° and can be an integral structure to ensure the structural strength of the limiting component 25; two limiting side plates 252 can be provided (e.g., Figure 6 As shown, there are two limiting side plates 252, one on the top and one on the bottom, located at the upper and lower ends of the limiting base plate 251 respectively. These limiting members 25 are C-shaped and can limit each other with the clamp body 1, which helps to improve the overall stability of the clamp device.

[0079] In some embodiments, such as Figures 19-31 As shown, the clamp body 1 is an integral clamp, and the integral clamp is bent at both ends in its extension direction to form a first bending piece 1a1 and a second bending piece 1b1 respectively; wherein, the first bending piece 1a1 and the corresponding second bending piece 1b1 together constitute the bending part 12, and the bending part 12 constituted by the first bending piece 1a1 and the corresponding second bending piece 1b1 is a split bending part.

[0080] In at least one embodiment, the clamp body 1 is an integral structure. One end of the integral clamp in the extension direction is provided with a first bending piece 1a1, and the other end is provided with a second bending piece 1b1. The first bending piece 1a1 and the corresponding second bending piece 1b1 together constitute a split bending part. When using this integral clamp, the integral clamp can be first fitted onto the first component 31 at a suitable height from one end of the first component 31, and then the split bending part can be inserted into the end of the corresponding second component 32. The split bending part can then be connected and fixed to the corresponding second component 32 by the first fastener 21.

[0081] In at least one embodiment, such as Figures 19-31As shown, the bending portions 12 are provided in plurality, one of the bending portions 12 is a split bending portion, and the others are integral bending portions; at least one side of the opposite sides of the integral hoop comprises the integral bending portion, or / and, the side opposite to the split bending portion of the integral hoop comprises the integral bending portion.

[0082] In at least one embodiment, the integral hoop can have multiple bending portions 12, such as Figures 19-20 As shown in the ninth hoop device, the hoop body 1 is an integral hoop, and has two bending portions 12, one end of the extending direction of the hoop body 1 is provided with a first bending piece 1a1, and the other end is provided with a second bending piece 1b1, the first bending piece 1a1 and the second bending piece 1b1 jointly constitute a split bending portion, in addition, the side opposite to the split bending portion of the integral hoop can also be provided with an integral bending portion (the left side shown in the figure). In this way, when using the hoop device, the integral hoop can be sleeved on the first member 31 at a suitable height from one end of the first member 31, and then the split bending portion is inserted into the end of the corresponding second member 32, and then the split bending portion is connected and fixed with the corresponding second member 32 through a first fastener 21, and the integral bending portion is connected and fixed with the corresponding second member 32 through another first fastener 21, so as to finally realize the connection and fixation of the hoop device to one first member 31 and two second members 32.

[0083] In at least one embodiment, the integral hoop can have multiple bending portions 12, such as Figure 24 As shown in the eleventh hoop device, the hoop body 1 is an integral hoop, and has three bending portions 12, one end of the extending direction of the hoop body 1 is provided with a first bending piece 1a1, and the other end is provided with a second bending piece 1b1, the first bending piece 1a1 and the second bending piece 1b1 jointly constitute a split bending portion, in addition, the opposite sides (the left and right sides shown in the figure) of the integral hoop each have an integral bending portion. In this way, when using the hoop device, the integral hoop can be sleeved on the first member 31 at a suitable height from one end of the first member 31, and then the split bending portion is inserted into the end of the corresponding second member 32, and the integral bending portions on the left and right sides are respectively inserted into the end of the corresponding second member 32, and then the three bending portions 12 (one split bending portion and two integral bending portions) are connected and fixed with the corresponding second member 32 through three first fasteners 21, so as to finally realize the connection and fixation of the hoop device to one first member 31 and three second members 32.

[0084] In at least one embodiment, the integral hoop can have multiple bending portions 12, such as Figure 28The thirteenth clamp device shown has a clamp body 1 that is an integral clamp and has four bends 12. One end of the clamp body 1 in the extension direction is provided with a first bend 1a1 and the other end is provided with a second bend 1b1. The first bend 1a1 and the second bend 1b1 together form a split bend. In addition, the two sides opposite to the integral clamp (the left and right sides in the figure) and the side opposite to the split bend have an integral bend. Thus, when using this clamp device, the integrated clamp can first be fitted onto the first component 31 at a suitable height from one end of the first component 31, and then the split bending part can be inserted into the end of the corresponding second component 32. The integrated bending parts on the left, right and front sides can be inserted into the end of the corresponding second component 32 respectively. Then, the four bending parts 12 (one split bending part and three integrated bending parts) can be connected and fixed to the corresponding second component 32 by the four first fasteners 21. Finally, the clamp device can connect and fix one first component 31 and four second components 32.

[0085] In some embodiments, such as Figures 1-5 or Figures 6-7 or Figure 19 or Figure 28 As shown, the integrated bending part includes two opposing connecting side plates 121. The distance between the two connecting side plates 121 gradually decreases in the direction that gradually moves away from the first component 31. The connecting side plate 121 is provided with a second a connecting hole 1211, and the second component 32 is provided with a second b connecting hole 321. The first fastener 21 is used to pass through the second a connecting hole 1211 and the second b connecting hole 321.

[0086] In at least one embodiment, whether it is an integral clamp or a split clamp, the integral bent portion of the clamp body 1 includes two opposing connecting side plates 121. Figures 1-5 Taking the first type of clamp device as an example, when connecting a first component 31 and two second components 32 through this clamp device, the first clamp 1a and the second clamp 1b can be placed on opposite sides of the first component 31 and at a suitable height. Then, the two bent edge buckles 13 at one end are clamped together by a snap-fit ​​block 24, and the two bent edge buckles 13 at the other end are clamped together by another snap-fit ​​block 24. With the snap-fit ​​block 24 clamping the two bent edge buckles 13 together, the clamp body 1 clamps the first component 31 once.

[0087] In addition, since the left side and the right side of the hoop body 1 are respectively provided with the integral bending part, the two connecting side plates 121 of the integral bending part are respectively provided with the second connecting hole 1211 for the first fastener 21, and the spacing between the two connecting side plates 121 gradually decreases in the direction away from the first component 31, which is equivalent to that the two connecting side plates 121 are arranged at an angle. Thus, in the case that the cross-sectional shape of the second component 32 corresponding to the integral bending part is an open ring shape with an opening, for example, the second component 32 is a C-shaped crossbeam, as shown in Figure 3 the first bolt in the first fastener 21 can be sequentially inserted into the second connecting hole 321 of the C-shaped crossbeam and the second connecting hole 1211 of the two connecting side plates 121, and then the first nut in the first fastener 21 can be locked on the first bolt from the cross-sectional opening of the C-shaped crossbeam. With the locking of the first nut, the two connecting side plates 121 gradually approach each other. Since the two connecting side plates 121 are initially arranged at an angle rather than in parallel, with the gradual locking of the first nut, the two connecting side plates 121 are more easily deformed in opposite directions to drive the adjacent side of the fitting part 11 on the side of the bending part 12 to further tightly hold the first component 31, that is, to realize the secondary holding of the first component 31 in the process of locking the first nut on the first bolt.

[0088] In some embodiments, as shown in Figures 9-10 or Figures 12-13 or Figure 16 one of the first bending piece 1a1 and the corresponding second bending piece 1b1 is a set bending piece, and the other is a marked bending piece, and the end of the set bending piece is bent towards the direction of the marked bending piece.

[0089] In at least one embodiment, regardless of whether the hoop body 1 is an integral hoop or a split hoop, as long as the bending part 12 is a split bending part, one of the first bending piece 1a1 and the corresponding second bending piece 1b1 in the split bending part can be a set bending piece, and the other can be a marked bending piece, and the end of the set bending piece can be provided with a first bending edge rib 171 towards the direction of the marked bending part 12.

[0090] In at least one embodiment, as shown in Figures 9-10The third type of hoop device is shown as an example, the first bending piece 1a1 of the first end of the first hoop 1a is a set bending piece, and the second bending piece 1b1 of the first end of the second hoop 1b is a designated bending piece. In this case, the first bending edge rib 171 is provided on the first bending piece 1a1 of the first end of the first hoop 1a towards the corresponding second bending piece 1b1; the first bending piece 1a1 of the second end of the first hoop 1a is a designated bending piece, and the second bending piece 1b1 of the second end of the second hoop 1b is a set bending piece. In this case, the second bending piece 1b1 of the second end of the second hoop 1b is provided with a first bending edge rib 171 towards the corresponding first bending piece 1a1. In the case where the hoop device is not used, there is a gap between the first bending edge rib 171 and the corresponding designated bending piece. When the hoop device is used, as the first nut in the first fastener 21 gradually locks on the first bolt, the first bending edge rib 171 gradually approaches and abuts against the designated bending piece. The first bending edge rib 171 plays a role in limiting the relative deformation displacement amount of the first bending piece 1a1 and the second bending piece 1b1, and can prevent the relative deformation amount of the first bending piece 1a1 and the second bending piece 1b1 from being too large to recover. In addition, the presence of the first bending piece 1a1 can also ensure that after the hoop body 1 is tightly held on the first member 31, the first bending piece 1a1 and the second bending piece 1b1 can be supported by the first bending edge rib 171, which is beneficial to the stability of the entire hoop device.

[0091] In some embodiments, as shown in Figures 9-10 or Figures 12-13 or Figure 16 The angle between the first bending edge rib 171 and the set bending piece is less than 90°.

[0092] In at least one embodiment, still taking the third type of hoop device shown in Figures 9-10 The angle between the first bending edge rib 171 and the adjacent set bending piece is less than 90°, that is, the bending angle of the first bending edge rib 171 relative to the set bending piece is greater than 90°. In this way, the first bending edge rib 171 not only plays a role in limiting the relative deformation displacement amount of the first bending piece 1a1 and the second bending piece 1b1, but also allows a certain deformation, that is, as the first nut in the first fastener 21 gradually locks, the first bending edge rib 171 with this angle contacts the designated bending piece, which can deform by a larger angle, while preventing the deformation from being too large, to ensure that the first bending piece 1a1 and the second bending piece 1b1 can continue to deform relative to the displacement, which is more conducive to the tightening of the hoop.

[0093] In some embodiments, as shown in Figure 11 or Figures 14-15 or Figure 18 orFigure 21 or Figures 24-25 or Figures 28-29 As shown, the end of the calibration bending piece is bent toward the direction of the setting bending piece and is provided with a second bending edge rib 172, wherein the first bending edge rib 171 is located inside the second bending edge rib 172.

[0094] In at least one embodiment, in addition to the first bending edge rib 171 being provided in the direction of the setting bending piece toward the calibration bending piece, the calibration bending piece is also provided with a second bending edge rib 172 toward the setting bending piece, and the first bending edge rib 171 is located inside the second bending edge rib 172. The second bending edge rib 172 can shield the first bending edge rib 171, which can improve the overall aesthetics. Furthermore, when the cross-sectional shape of the second member 32 is an open ring shape with an opening, the second bending edge rib 172 can also protect the first bending edge rib 171.

[0095] In at least one embodiment, such as Figure 11 As shown, a fourth type of clamping device is provided. Compared with the aforementioned third type of clamping device, the fourth type of clamping device differs in that a second bending edge rib 172 is provided at the end of the calibration bending piece facing the direction of the setting bending piece. In at least one embodiment, as... Figures 14-15 As shown, a sixth type of clamping device is provided. Compared with the aforementioned fifth type of clamping device, the sixth type of clamping device differs in that a second bending edge rib 172 is provided at the end of the calibration bending piece facing the direction of the setting bending piece. In at least one embodiment, as... Figure 18 As shown, an eighth type of clamping device is provided. Compared with the aforementioned seventh type of clamping device, the eighth type of clamping device is different in that a second bending edge rib 172 is provided at the end of the calibration bending piece in the direction of the setting bending piece.

[0096] In some embodiments, such as Figures 1-7 or Figure 19 or Figure 21 or Figures 24-25 or Figure 29 As shown, the calibration side of the clamp body 1 is the side adjacent to the side of the clamp body 1 with the bent part 12, and the end of the calibration side of the clamp body 1 is provided with a protruding rib 15 in the direction away from the first component 31.

[0097] In at least one embodiment, to Figures 1-5 Taking the first type of clamp device shown as an example, the clamp body 1 has a protruding rib 15 on the side adjacent to the bent portion 12, that is, Figures 1-5The end of the front side and the rear side of the shown hoop body 1 has a convex rib 15, which is not in contact with the first component 31, and the convex rib 15 corresponds to a space for avoiding, and specifically forms a space for avoiding between the convex rib 15 and the first component 31. When the first nut in the first fastener 21 is locked, the two connecting side plates 121 of the integral bending part are relatively deformed and displaced, which can drive the space for avoiding at the adjacent convex rib 15 to be reduced, and thus it is more convenient to drive the further holding of the abutting part 11 adjacent to the bending part 12 to the first component 31.

[0098] In some embodiments, as shown in Figures 21-23 or Figures 25-27 or Figures 29-31 As shown, the abutting part 11 of the opposite sides of the hoop body 1 is respectively provided with a third a connecting hole 16, and the opposite side walls of the first component 31 are respectively provided with a third b connecting hole 312; and the fastening structure further comprises a third fastener 23, and the third fastener 23 is used for penetrating the third a connecting hole 16 and the third b connecting hole 312.

The third fastener 23 can be a third bolt, which penetrates the third a connecting hole 16 of the abutting part 11 of the opposite sides of the hoop body 1 and the third b connecting hole 312 of the opposite side walls of the first component 31. The third fastener 23 can also be a rivet, and the third a connecting hole 16 of the abutting part 11 of one side of the hoop body 1 and the third b connecting hole 312 of the side wall of the first component 31 are fixed by one rivet, and the third a connecting hole 16 of the abutting part 11 of the other side of the hoop body 1 and the third b connecting hole 312 of the side wall of the first component 31 are fixed by another rivet.

In at least one embodiment, as shown in Figures 25-27 A twelfth hoop device is provided, and compared with the eleventh hoop device, the difference between the twelfth hoop device and the eleventh hoop device is that the opposite sides of the hoop body 1 are respectively provided with a third a connecting hole 16. In at least one embodiment, as shown in Figures 29-31 A fourteenth hoop device is provided, and compared with the thirteenth hoop device, the difference between the fourteenth hoop device and the thirteenth hoop device is that the opposite sides of the hoop body 1 are respectively provided with a third a connecting hole 16.

[0103] In some embodiments, the cross-sectional shape of the first member 31 is a closed loop shape, and / or the cross-sectional shape of the second member 32 is a closed loop shape or an open loop shape with an opening on at least one side.

[0104] In at least one embodiment, such as Figures 1-20 As shown, the cross-sectional shape of the first component 31 can be a closed loop shape, for example, the first component 31 is a square column, and the cross-sectional shape of the second component 32 can also be an open loop shape with an opening on at least one side, for example, the second component 32 is a C-shaped beam. Figures 22-31 As shown, the cross-sectional shape of the second component 32 can also be a closed loop shape, such as a square beam; in this case, the second component 32 has second b connecting holes 321 on opposite sides for the first fastener 21 to pass through.
