Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and particularly to a hoop assembly and a photovoltaic support. Background Art

[0002] In the existing photovoltaic system, split bearings are widely used in the main shaft support part of the photovoltaic system because of their convenient installation and maintenance. A split bearing usually consists of two or more arc-shaped parts, which are assembled on the main shaft and form a gap around the main shaft. Although this structural design is convenient for installation and maintenance, there are also some problems. During the rotation of the main shaft, due to the gap between the split bearing and the main shaft, displacement may occur between the main shaft and the split bearing, resulting in the bearing not rotating with the main shaft. When the bearing deviates from the main shaft and does not rotate with it, torsion will be generated between the bearing and the main shaft. In addition, the bearing and the bearing seat cannot ensure concentricity and are not in the same vertical direction as the column top seat, so that the column top seat receives a greater reaction force and the force distribution is uneven. When the force borne by the column top seat is less than the force borne by the main shaft, the column top seat will be damaged, thereby reducing the service life of the column top seat.

[0003] Therefore, how to improve the technical defects existing in the prior art has always been an urgent problem for those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide a hoop assembly and a photovoltaic support, which can make the main shaft fit with the split bearing, thereby restricting the offset of the split bearing and enabling the split bearing to rotate better.

[0005] The technical solution provided by the present invention is as follows:

[0006] A hoop assembly suitable for a main shaft for installing a split bearing, comprising:

[0007] Two hoop members adapted to surround the outside of the main shaft;

[0008] Each hoop member includes a surrounding portion and a supporting portion. The surrounding portions of the two hoop members are used to jointly surround the main shaft to install the hoop assembly on the main shaft; the supporting portion is connected to the surrounding portion. When the hoop member surrounds the main shaft, the supporting portion is adapted to pass through the gap formed by the split bearing around the main shaft to restrict the relative movement of the split bearing with respect to the main shaft.

[0009] In some embodiments, the surrounding portion has a U-shaped plate structure, and connection portions are provided at both ends of the surrounding portion in terms of arc length; the two surrounding portions are connected through the connection portions, and the U-shaped openings of the two surrounding portions are arranged opposite to each other.

[0010] In some embodiments, one of the two connection portions on the surrounding portion is provided with a supporting portion;

[0011] When two enclosing parts are connected, the two supporting parts on the two enclosing parts are respectively located on both sides of the arc length of the enclosing part, and the two supporting parts are adapted to be respectively inserted into two gaps formed on the circumferential side of the main shaft by the split bearing.

[0012] In some embodiments, both connecting parts on the enclosing part are provided with supporting parts;

[0013] The supporting part has a plate-like structure. When the two enclosing parts are connected, the four supporting parts on the two enclosing parts are pairwise opposite, and the two groups of opposite supporting parts are adapted to be respectively inserted into two gaps formed on the circumferential side of the main shaft by the split bearing.

[0014] In some embodiments, a buffer part is provided between two opposite supporting parts.

[0015] In some embodiments, one end of the supporting part far from the connecting part curls inward toward the opposite supporting part to form a buffer part.

[0016] In some embodiments, the hoop member further includes a first stop portion and a second stop portion;

[0017] The first stop portion is provided on the enclosing part, and the second stop portion is provided at one end of the supporting part far from the enclosing part. When two hoop members are clamped around the main shaft, the first stop portion and the second stop portion are respectively used to abut against both ends of the split bearing in the axial direction of the main shaft.

[0018] In some embodiments, the enclosing part has a U-shaped plate-like structure, and one side of the enclosing part facing the supporting part extends toward the direction away from the U-shaped opening to form a first stop portion;

[0019] The second stop portion is detachably installed on the supporting part, and the distance between the second stop portion and the first stop portion is adjustable.

[0020] In some embodiments, the second stop portion includes a mounting member and an adjusting bolt;

[0021] The mounting member includes a first docking block and a second docking block arranged at an angle. The first docking block is connected to the supporting part, the second docking block is provided with a threaded hole, the adjusting bolt is screwed into the threaded hole, and one end of the adjusting bolt passes through the second docking block to abut against the split bearing;

[0022] When the adjusting bolt is rotated, the adjusting bolt moves toward or away from the enclosing part to change the distance between the second stop portion and the first stop portion.

[0023] This application also provides a photovoltaic bracket, including:

[0024] A main shaft, a bearing assembly, and the hoop assembly provided in any of the above embodiments;

[0025] The bearing assembly includes a bearing seat and a split bearing. The bearing seat is provided with a bearing hole, and the split bearing is installed in the bearing hole. The main shaft passes through the split bearing so that the main shaft can rotate relative to the bearing seat; and,

[0026] The split bearing includes a first bearing portion and a second bearing portion, and the first bearing portion and the second bearing portion form two gaps on the circumferential side of the main shaft. The clamp assembly is installed on the main shaft, and the support portion in the clamp assembly is passed through the two gaps to limit the movement of the split bearing relative to the main shaft.

[0027] The technical effects of this application are:

[0028] 1. In the present application, by providing a support portion on the clamp component, when the clamp component is clamped to the outside of the main shaft, the support portion can be used to fill the gap between the split bearing and the main shaft, thereby limiting the circumferential movement of the split bearing relative to the main shaft, making it difficult for the split bearing to shift. At the same time, the support portion and the bearing seat outside the split bearing can jointly pressurize the split bearing to limit the radial shaking of the split bearing, so that the split bearing can fit with the main shaft, making it easier for the main shaft to drive the external split bearing to rotate together when rotating, thereby achieving the purpose of following the rotation. Moreover, during the rotation process, the support portion rotates with the main shaft, which can play a role in promoting the rotation of the split bearing, and the following rotation effect is better.

[0029] 2. In the present application, the support part is plate-shaped and is arranged at both ends of the arc length of the enclosed part. When the clamp assembly is clamped on the outside of the main shaft, the two support parts on the two clamp parts that are opposite to each other can be inserted into the gap of the split bearing and limit the split bearing. The structural setting is lighter and simpler, which is conducive to lightweight production. In addition, a buffer part is provided between the two opposing support parts to buffer the collision between the two clamp parts, and at the same time, an adjustment space is reserved, so that the user can fine-tune the first bearing part and the second bearing part without disassembling the entire split bearing, thereby optimizing the operating performance of the split bearing.

[0030] 3. In the present application, the clamping member is provided with a first stopper and a second stopper, which respectively abut against the two ends of the split bearing in the axial direction, and can strengthen the contact fixation between the clamping assembly and the split bearing. At the same time, the first stopper and the second stopper cooperate with the split bearing to limit the axial displacement of the clamping assembly, increase the contact stability between the main shaft and the clamping assembly, and ensure the limiting effect of the support part on the split bearing.

[0031] 4. In this application, the second stop portion is a detachable structure, which is beneficial for users to assemble the hoop component to the main shaft, making the installation convenient. Among them, the second stop portion includes a mounting member and an adjusting bolt. The adjusting bolt is screwed onto the mounting member. By rotating the adjusting bolt, the user can change the distance between it and the first stop portion, thereby finely adjusting the axial clearance of the split bearing and optimizing the operating performance of the split bearing. Moreover, the setting of the adjusting bolt can also make the hoop component adapt to split bearings of more sizes, with a wide range of applications and strong practicability.

[0050] In the embodiments shown in the drawings, the indication of directions (such as up, down, left, right, front, and back) is used to explain that the structures and movements of various components of the present application are not absolute but relative. When these components are in the positions shown in the drawings, these explanations are appropriate.

[0051] In addition, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0052] In the existing photovoltaic system, split bearings are widely used in the main shaft support part of the photovoltaic system because of their characteristics of easy installation and maintenance. The split bearing usually consists of two or more arc-shaped components, which are assembled on the main shaft and form a gap on the circumferential side of the main shaft. Although this structural design is convenient for installation and maintenance, there are also some problems. When the main shaft rotates, due to the gap between the split bearing and the main shaft, the split bearing will shake and displace relative to the main shaft, resulting in the offset and non-rotation following of the split bearing, thereby affecting the performance of the entire photovoltaic bracket.

[0053] In this regard, referring to Figures 1 to 3 , the present application provides a hoop assembly 100, which can be used as an auxiliary installation structure to make the split bearing 300 fit with the main shaft 200, and it is not easy to have relative displacement, so as to achieve the purpose of restricting the offset of the split bearing 300 and enabling the split bearing 300 to rotate better.

[0054] In a specific embodiment, the hoop assembly 100 includes two hoop members 110, and the two hoop members 110 can surround the outside of the main shaft 200. Each of the two hoop members 110 further includes a surrounding portion 111 and a supporting portion 112. The surrounding portion 111 is preferably adapted to the outer wall contour of the main shaft 200, and the surrounding portions 111 of the two hoop members 110 can jointly embrace the main shaft 200 to install the hoop assembly 100 on the main shaft 200. The supporting portion 112 is connected to the surrounding portion 111. When the hoop member 110 embraces the main shaft 200, the supporting portion 112 is adapted to pass through the gap 330 formed by the split bearing 300 on the circumferential side of the main shaft 200 to limit the movement of the split bearing 300 relative to the main shaft 200.

[0055] The split bearing 300 usually includes a first bearing portion 310 and a second bearing portion 320 which are arranged oppositely up and down, and there are two gaps 330 formed by the first bearing portion 310 and the second bearing portion 320 on the circumferential side of the main shaft 200. In this embodiment, by providing the supporting portion 112 on the hoop member 110, when the hoop assembly 100 is embraced on the outside of the main shaft 200, the supporting portion 112 can be used to fill the two gaps 330 between the split bearing 300 and the main shaft 200, and resist the first bearing portion 310 and the second bearing portion 320, thereby restricting the circumferential movement of the split bearing 300 relative to the main shaft 200. The split bearing 300 is not easy to offset, ensuring that the split bearing 300 is concentric with the bearing seat 400 and in the same vertical direction as the column top seat 500, and thus extending the service life of the column top seat 500.

[0056] In another embodiment, the first bearing portion 310 includes two first split bearings disposed opposite to each other left and right, the second bearing portion 320 includes two second split bearings disposed opposite to each other left and right, and four gaps 330 are formed on the circumferential side of the main shaft 200 between the two first split bearings and the two second split bearings. When the hoop assembly 100 is clamped to the outside of the main shaft 200, it can fill the four gaps 330 between the split bearing 300 and the main shaft 200 by means of the support portion 112, and respectively abut against the two first split bearings and the two second split bearings, thereby restricting the circumferential movement of the split bearing 300 relative to the main shaft 200.

[0057] In addition, the support portion 112 in this embodiment can also press the inner and outer sides of the split bearing 300 together with the bearing seat 400, thereby restricting the radial sway of the split bearing 300, enabling the split bearing 300 to fit with the main shaft 200, reducing the friction and collision between the split bearing 300 and the main shaft 200, and making it easier for the main shaft 200 to drive the split bearing 300 to rotate together when rotating, thereby achieving the purpose of following rotation. Moreover, during the rotation process, the support portion 112 rotates together with the main shaft 200, and at the same time, the support portion 112 abuts against the first bearing portion 310 and the second bearing portion 320, thereby playing a role in promoting the rotation of the split bearing 300, and the following rotation effect is better.

[0058] Specifically, referring to Figure 1 、 Figure 3 and Figure 4 , the enclosing portion 111 has a U-shaped plate-like structure, and connecting portions 113 are provided at both ends of the enclosing portion 111 in terms of arc length. The two enclosing portions 111 are connected through the connecting portions 113, and the U-shaped openings of the two connected enclosing portions 111 are disposed opposite to each other. In this embodiment, by providing the enclosing portion 111 with a U-shaped plate-like structure, while ensuring the degree of fit with the main shaft 200, the material cost can be reduced, and lightweight production can be achieved. Moreover, the lighter hoop assembly 100 is also more conducive to on-site assembly by users, and the installation difficulty is low.

[0059] In an exemplary embodiment, one of the two connecting portions 113 on the enclosing portion 111 is provided with a support portion 112. When the two enclosing portions 111 are connected, the two support portions 112 on the two enclosing portions 111 are respectively located on both sides of the enclosing portion 111 in terms of arc length. In practical applications, two gaps 330 are mostly formed on the circumferential side of the main shaft 200 between the first bearing portion 310 and the second bearing portion 320. Thus, the two support portions 112 can respectively pass through the two gaps 330 to support and limit the first bearing portion 310 and the second bearing portion 320.

[0060] In this embodiment, the two supporting parts 112 simultaneously support and limit the upper and lower first bearing parts 310 and second bearing parts 320. The supporting part 112 may be in a block structure, and the upper and lower opposite side walls thereof respectively abut against one ends of the first bearing part 310 and the second bearing part 320 that are close to each other; alternatively, the supporting part 112 may include two supporting plates arranged oppositely, and the two supporting plates are connected to the surrounding part 111 and respectively abut against one ends of the first bearing part 310 and the second bearing part 320 that are close to each other. There is no limitation here, and all are within the protection scope of this application.

[0061] In a preferred embodiment, referring to Figures 3 to 5 , supporting parts 112 are provided on both connecting parts 113 of the surrounding part 111, and the supporting part 112 is preferably in a plate structure. When the two surrounding parts 111 are connected, the four supporting parts 112 on the two surrounding parts 111 are opposite to each other in pairs. Taking two opposite supporting parts 112 as a group, the two groups of supporting parts 112 can be respectively inserted into two gaps 330 formed on the circumferential side of the split bearing 300 around the main shaft 200 to support and limit the first bearing part 310 and the second bearing part 320.

[0062] In this embodiment, the supporting part 112 of the upper hoop member 110 is only used to support and limit the upper first bearing part 310, and the supporting part 112 of the lower hoop member 110 is only used to support and limit the lower second bearing part 320, which is more conducive to the user to adjust the upper or lower hoop member 110 to achieve the individual adjustment of the first bearing part 310 and the second bearing part 320, and the operability is better. Moreover, the plate structure of the supporting part 112 in this embodiment is set to be lighter and simpler, which is conducive to lightweight production.

[0063] In actual production, due to the different functions of the connecting part 113 and the supporting part 112, there will be a height difference between them. The distance between the connecting plates of the two hoop members 110 is smaller for the user to lock and fix, so that the connection strength of the hoop assembly 100 is higher and the stability between the structures is ensured; while the distance between the supporting parts 112 of the two hoop members 110 will be a little larger so as to apply pressure to the first bearing part 310 and the second bearing part 320 together with the bearing seat 400.

[0064] At this time, considering the distance between the supporting portions 112 of the two hoop members 110, it is preferably to provide a buffer portion 114 between the two opposite supporting portions 112, which can buffer the collision between the two hoop members 110 and improve the structural stability. In addition, the provision of the buffer portion 114 can also reserve an adjustment space for the first bearing portion 310 and the second bearing portion 320, facilitating the user to finely adjust the first bearing portion 310 and the second bearing portion 320 without disassembling the entire split bearing 300. For example, adjusting the radial clearance of the split bearing 300 to optimize the operating performance of the split bearing 300. Preferably, the connecting portions 113 of the two hoop members 110 are fixed by bolts, which is more conducive to the user to adjust the distance between the two hoop members 110, thereby adjusting the radial clearance of the split bearing 300, and the operation is convenient and fast.

[0065] In a specific embodiment, the ends of the two opposite supporting portions 112 away from the connecting portion 113 are curled inward in a direction approaching each other to form the above-mentioned buffer portion 114; this structure can be formed by bending a plate through machining, with convenient forming and low production cost. Preferably, the hoop member 110 in this embodiment is integrally formed and can be mass-produced and used.

[0066] Of course, in actual production, it can also be that one of the two opposite supporting portions 112 is provided with a buffer portion 114, that is, one of the two opposite supporting portions 112, the end away from the connecting portion 113 is curled inward in the direction of the other supporting portion 112 to form the buffer portion 114.

[0067] Furthermore, referring to Figures 1 to 3 , the hoop member 110 further includes a first blocking portion 115 and a second blocking portion 116. The first blocking portion 115 is provided on the surrounding portion 111, and the second blocking portion 116 is provided at the end of the supporting portion 112 away from the surrounding portion 111. When the two hoop members 110 are clamped around the outer side of the main shaft 200, the first blocking portion 115 and the second blocking portion 116 are respectively used to abut against the two ends of the split bearing 300 in the axial direction of the main shaft 200, which can strengthen the contact fixation between the hoop assembly 100 and the split bearing 300. At the same time, the first blocking portion 115 and the second blocking portion 116 cooperate with the split bearing 300 to also limit the axial displacement of the hoop assembly 100, increasing the contact stability between the main shaft 200 and the hoop assembly 100, and ensuring that the supporting portion 112 can play a role in restricting and supporting the split bearing 300.

[0068] Specifically, referring to Figure 3, the enclosing portion 111 extends toward one side of the support portion 112 in a direction away from the U-shaped opening to form the above-mentioned first stop portion 115. This structure can be formed by bending a plate through machining, which is convenient to form and has low production costs. Among them, the second stop portion 116 is preferably detachably mounted on the support portion 112. In this way, when assembling the clamp assembly 100, the user can directly insert the end of the support portion 112 away from the enclosing portion 111 into the gap 330 between the split bearing 300 and the main shaft 200 until the first stop portion 115 on the enclosing portion 111 abuts against one end of the split bearing 300, and then the two clamp components 110 are locked and connected; after the two clamp components 110 are assembled, the second stop portion 116 is installed, which is convenient and quick to install, and there is no need to consider structural interference issues.

[0069] Preferably, the distance between the second stopper 116 and the first stopper 115 is adjustable, and the user can adjust the axial clearance of the split bearing 300 by changing the distance between the first stopper 115 and the second stopper 116, thereby optimizing the operating performance of the split bearing 300. Moreover, the adjustable distance between the first stopper 115 and the second stopper 116 can also make the clamp assembly 100 adaptable to split bearings 300 of more sizes, with a wide range of applications and strong practicality.

[0070] Specifically, see Figures 4 to 6 The second stopper 116 includes a mounting member 1161 and an adjusting bolt 1162, wherein the mounting member 1161 is generally "L"-shaped, including a first docking block 11611 and a second docking block 11612 arranged at an angle, the first docking block 11611 is connected to the support portion 112, and the second docking block 11612 is provided with a threaded hole, the adjusting bolt 1162 is screwed into the threaded hole, and one end of the adjusting bolt 1162 passes through the second docking block 11612 to abut against the split bearing 300; when the adjusting bolt 1162 is rotated, the adjusting bolt 1162 moves toward or away from the enclosing portion 111 to change the distance between the second stopper 116 and the first stopper 115.

[0071] In this embodiment, the adjusting bolt 1162 is used as an adjusting structure and can also support the end of the split bearing 300 away from the first stopper 115, and the structural integration is relatively high; and by setting the adjusting bolt 1162 to adjust the spacing, the spacing between the first stopper 115 and the second stopper 116 can be fine-tuned, which is more conducive to the user to adjust the axial clearance of the split bearing 300, and the adjustment accuracy is high. In addition, the threaded fit between the adjusting bolt 1162 and the threaded hole also has a self-locking function, the stability after adjustment is better, and the structural setting is more reasonable and practical.

[0072] See also Figure 1 and Figure 2, this application also discloses a photovoltaic support, which includes a main shaft 200, a bearing assembly, and the hoop assembly 100 provided in any of the above embodiments. The bearing assembly includes a bearing seat 400 and a split bearing 300. The bearing seat 400 is provided with a bearing hole, and the split bearing 300 is installed in the bearing hole; the main shaft 200 passes through the split bearing 300 so that the main shaft 200 can rotate relative to the bearing seat 400. Among them, the split bearing 300 includes a first bearing portion 310 and a second bearing portion 320 that are oppositely arranged up and down. The first bearing portion 310 and the second bearing portion 320 form two gaps 330 on the circumferential side of the main shaft 200. The hoop assembly 100 is installed on the main shaft 200, and the support portion 112 in the hoop assembly 100 can pass through the two gaps 330, thereby restricting the movement of the split bearing 300 relative to the main shaft 200, enabling the split bearing 300 to fit with the main shaft 200, so that the main shaft 200 can more easily drive the split bearing 300 to rotate together when rotating, and further achieving the purpose of following rotation. Moreover, during the rotation process, the support portion 112 can also push the split bearing 300 to rotate. Compared with only relying on the main shaft 200 to drive the rotation, the following rotation effect is better, which is beneficial to improving the response speed of the photovoltaic support and ensuring that the photovoltaic support can accurately drive the photovoltaic module to follow the sun's movement.

[0073] Specifically, the photovoltaic support further includes a plurality of columns and purlins. The plurality of columns are arranged at intervals in a straight line in sequence, and column top seats 500 are provided at the tops of the plurality of columns for docking with the bearing assembly. The main shaft 200 sequentially passes through the split bearings 300 on the plurality of column top seats 500, and the plurality of purlins are sequentially installed on the main shaft 200 for installing photovoltaic modules. The main shaft 200 can rotate relative to the bearing seat 400 within the split bearing 300, thereby driving the purlins and the photovoltaic modules to rotate synchronously.

[0074] In this embodiment, in addition to improving the following rotation effect of the split bearing 300, the hoop assembly 100 can also limit the offset of the split bearing 300, ensuring that the split bearing 300 is concentric with the bearing seat 400 and in the same vertical direction as the column top seat 500, thereby extending the service life of the column top seat 500.

[0075] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0076] It should be noted that the above embodiments can be freely combined according to needs. The above are only the preferred embodiments of this application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of this application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this application.
