Description

Technical Field

[0001] This utility model relates to the technical field of installation equipment for photovoltaic tracking brackets, and in particular to an installation component for photovoltaic tracking brackets. Background Technology

[0002] A solar photovoltaic tracking bracket is a special bracket designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system.

[0003] Currently, solar photovoltaic (PV) tracking brackets consist of a base, plastic bearings, and clamps. The plastic bearings typically employ an integrated double-sided stepped structure, requiring them to be installed into the base first, followed by the main shaft. While this installation method is usable, the relatively small clearance between the plastic bearings and the PV main shaft makes installation difficult, resulting in low installation efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an installation component for a photovoltaic tracking bracket to solve the problem that plastic bearings usually adopt an integrated double-sided stepped structure, which requires the plastic bearing to be installed into the base first and then the main shaft to be installed. However, due to the relatively small fit clearance between the plastic bearing and the main shaft, this installation method is difficult to operate, resulting in low installation efficiency of the photovoltaic main shaft.

[0005] To achieve the above objectives, this utility model provides an installation assembly for a photovoltaic tracking bracket, comprising a base having a bearing through-slot extending through the base; a photovoltaic main shaft, having an octagonal prism structure, passing through the bearing through-slot and used to connect a photovoltaic panel; a first arc-shaped bearing, slidably fitted within the bearing through-slot and capable of rotating along the inner wall of the bearing through-slot, having a first clamping groove abutting against the five end faces of the photovoltaic main shaft; and a second arc-shaped bearing, slidably fitted within the bearing through-slot and capable of rotating along the inner wall of the bearing through-slot, having a second clamping groove abutting against the five end faces of the photovoltaic main shaft; the first clamping groove and the second clamping groove combined to form a clamping groove for clamping the photovoltaic main shaft.

[0006] In an optional example, one end of the first arc-shaped bearing is provided with an outwardly extending first limiting step, which abuts against one end of the bearing through groove, and one end of the second arc-shaped bearing is provided with an outwardly extending second limiting step, which abuts against one end of the bearing through groove.

[0007] In an optional example, the other end of the first arc-shaped bearing is provided with an outwardly extending first limiting step two, which abuts against the other end of the bearing through groove, and the other end of the second arc-shaped bearing is provided with an outwardly extending second limiting step two, which abuts against the other end of the bearing through groove.

[0008] In one optional example, the first arc-shaped bearing and the first limiting step are integrally formed, the second arc-shaped bearing and the second limiting step are integrally formed, the first arc-shaped bearing and the first limiting step are separate, the first arc-shaped bearing is connected to the first limiting step by a snap-fit, and the second arc-shaped bearing and the second limiting step are separate, the second arc-shaped bearing is connected to the second limiting step by a snap-fit.

[0009] In one optional example, the first arc-shaped bearing and the first limiting step one are integrally formed, the first arc-shaped bearing and the first limiting step two are separate structures, the first arc-shaped bearing is connected to the first limiting step two by a snap-fit, and the second arc-shaped bearing, the second limiting step one, and the second limiting step two are integrally formed.

[0010] In one optional example, the first arc-shaped bearing and the first limiting step one are integrally formed, the second arc-shaped bearing and the second limiting step one and the second limiting step two are integrally formed, the first arc-shaped bearing and the first limiting step two are separate structures, and the first limiting step two is connected to the first arc-shaped bearing by bolts; the first limiting step two includes a stop plate, a sheet metal stop plate, a limiting bolt and a limiting nut, one end of the stop plate abuts against the first arc-shaped bearing, the sheet metal stop plate abuts against the other end of the stop plate, and the limiting bolt passes through the sheet metal stop plate, the stop plate, the first arc-shaped bearing and the first limiting step one in sequence, and is connected to the limiting nut by threads.

[0011] In an optional example, the photovoltaic tracking bracket mounting assembly further includes two symmetrically arranged limiting members. The first arc-shaped bearing and the first limiting step are integrally formed, and the second arc-shaped bearing and the second limiting step are integrally formed. The limiting members are fixedly connected to the photovoltaic main shaft. The end of the limiting member facing the base is provided with an abutting part, which abuts against the first limiting step and the second limiting step, and fixes the first limiting step and the second limiting step.

[0012] In an optional example, the base includes an upper base and a lower base connected to each other. The upper base has an upper arc-shaped portion, and upper connecting lugs extending outward are provided on both sides of the upper arc-shaped portion. The lower base has a lower arc-shaped portion, and lower connecting lugs extending outward are provided on both sides of the lower arc-shaped portion. The upper connecting lugs and the lower connecting lugs are fixedly connected by bolts. The upper arc-shaped portion and the lower arc-shaped portion combine to form a bearing through groove.

[0013] In an optional example, the base has a through mounting groove along the bearing groove direction, and the bottom of the base has a lower base bolt hole that communicates with the mounting groove. The mounting groove has two bolt fixing clips arranged along the bearing groove direction. The bolt fixing clips are symmetrically arranged with the lower base bolt hole as the center. A fixing nut is inserted between the two bolt fixing clips. A fixing bolt is inserted into the bottom of the lower base bolt hole. The fixing bolt and the fixing nut are fixedly connected by a threaded connection.

[0014] In an optional example, the mounting assembly for the photovoltaic tracking bracket further includes a support base connected to the base by fixing bolts. The support base includes a support portion connected to the base. The support portion is rectangular, with an upwardly extending long side limiting portion on the long side and a downwardly extending short side connecting portion on the short side. The long side limiting portion, the short side connecting portion, and the support portion are integrally formed.

[0015] The beneficial effect of this utility model is that it separates the photovoltaic plastic bearing into a first arc-shaped bearing and a second arc-shaped bearing. The first arc-shaped bearing and the second arc-shaped bearing adopt a split design and combine to form a double-sided stepped structure. This changes the problem of low installation efficiency of the photovoltaic spindle caused by the small assembly gap in the existing technology, where the plastic bearing is installed first and then the photovoltaic spindle is installed. This utility model allows the photovoltaic spindle to be installed into the base first, and then the plastic bearing is installed. The clamping groove of the plastic bearing is clamped on the photovoltaic spindle and pushed laterally into the base. The other end is connected by a buckle or bolt to form a double-step limit, which changes the existing technology. The installation method of the photovoltaic spindle reduces the installation difficulty and improves the installation efficiency. At the same time, the photovoltaic spindle adopts an octagonal column structure, which can effectively improve the structural strength of the photovoltaic spindle, the first arc bearing, and the second arc bearing, increasing the service life of the photovoltaic spindle and the plastic bearing. Furthermore, by adding the first limiting step one, the second limiting step one, the first limiting step two, and the second limiting step two, the two ends of the plastic bearing are restricted, preventing the plastic bearing from slipping off the base and causing failure, thus improving the service life of the installation components for the photovoltaic tracking bracket.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0034] Currently, existing spindles typically use a square tube structure. Since the four sides of the square tube are perpendicular to each other, the stress at the top corner of the plastic inner ring used to fix the square tube is relatively large, which can easily cause the plastic bearing to crack during long-term use.

[0035] In optional embodiment one, please refer to Figures 1 to 3 As shown, the present invention provides an installation assembly for a photovoltaic tracking bracket, comprising: a base 1, a photovoltaic main shaft 2, a first arc bearing 3, and a second arc bearing 4.

[0036] The base 1 has a bearing through groove 11 that runs through the base 1. The bearing through groove 11 is circular. The base 1 is made of metal material, such as aluminum alloy, stainless steel or other high-strength metal materials.

[0037] The photovoltaic spindle 2 has an octagonal prism structure. It passes through the bearing slot 11 and is used to connect the photovoltaic panel. The stress of the octagonal photovoltaic spindle 2 is relatively dispersed, so it has good structural strength, which can effectively reduce the deformation of the photovoltaic spindle 2 caused by rotational torque and improve its service life.

[0038] The first arc-shaped bearing 3 is slidably fitted into the bearing groove 11 and can rotate along the inner wall of the bearing groove 11. It has a first clamping groove 31 that abuts against the five end faces of the photovoltaic main shaft 2. The inner wall of the first arc-shaped bearing 3 has several first weight-reducing grooves. The first weight-reducing grooves can reduce the weight of the first arc-shaped bearing 3 and can generate a certain amount of deformation, which facilitates the insertion and fixing of the photovoltaic main shaft 2. The first arc-shaped bearing 3 can be made of plastic. The plastic first arc-shaped bearing 3 can absorb a certain amount of impact force and has a lighter structural weight.

[0039] The second arc-shaped bearing 4 is slidably fitted into the bearing groove 11 and can rotate along the inner wall of the bearing groove 11. It has a second clamping groove 41 that abuts against the five end faces of the photovoltaic main shaft 2. The inner wall of the second arc-shaped bearing 4 is provided with several second weight-reducing grooves. The second weight-reducing grooves can reduce the weight of the second arc-shaped bearing 4 and can generate a certain amount of deformation, which facilitates the insertion and fixing of the photovoltaic main shaft 2. The second arc-shaped bearing 4 can be made of plastic. The plastic material of the second arc-shaped bearing 4 can absorb a certain impact force and has a lighter structural weight.

[0040] The first clamping groove 31 and the second clamping groove 41 combine to form a clamping groove for holding the eight end faces of the photovoltaic spindle 2. The two ends of the first clamping groove 31 and the second clamping groove 41 are located on the same end face, and the clamping groove is octagonal. This effectively improves the structural strength of the clamping groove, reduces the torque generated by the rotation of the photovoltaic spindle 2, avoids deformation of the clamping groove due to excessive torque, and improves the service life of the plastic bearing.

[0041] Specifically, this invention separates the photovoltaic plastic bearing into a first arc-shaped bearing 3 and a second arc-shaped bearing 4. The first arc-shaped bearing 3 and the second arc-shaped bearing 4 adopt a split design and combine to form a double-sided stepped structure. This changes the problem of low installation efficiency of the photovoltaic spindle 2 caused by the small assembly clearance when the plastic bearing is installed first and then the photovoltaic spindle 2 is installed. This invention allows the photovoltaic spindle 2 to be installed into the base 1 first, and then the plastic bearing is installed. The clamping groove of the plastic bearing is clamped on the photovoltaic spindle 2 and pushed laterally into the base 1. The other end is connected by a buckle or bolt to form a double-step limit. This changes the installation method of the photovoltaic spindle 2, reduces the installation difficulty of the photovoltaic spindle 2, and improves the installation efficiency of the photovoltaic spindle 2. At the same time, the photovoltaic spindle 2 adopts an octagonal prism structure, which can effectively improve the structural strength of the photovoltaic spindle 2, the first arc-shaped bearing 3 and the second arc-shaped bearing 4, and increase the service life of the photovoltaic spindle 2 and the plastic bearing.

[0042] Please see Figures 1 to 3 As shown, in order to limit the displacement of the plastic bearing along the spindle axis, one end of the first arc bearing 3 is provided with an outwardly extending first limiting step 32, which abuts against one end of the bearing through groove 11. One end of the second arc bearing 4 is provided with an outwardly extending second limiting step 42, which abuts against one end of the bearing through groove 11.

[0043] Specifically, this embodiment avoids the slippage failure of the first arc bearing 3 and the second arc bearing 4 from one side of the base 1 during rotation by adding a first limiting step 32 and a second limiting step 42, thus ensuring the stability and reliability of the photovoltaic tracking system.

[0044] Please see Figures 1 to 3 As shown, in order to limit the displacement of the plastic bearing along the spindle axis, the other end of the first arc bearing 3 is provided with an outwardly extending first limiting step 33, which abuts against the other end of the bearing through groove 11. The other end of the second arc bearing 4 is provided with an outwardly extending second limiting step 43, which abuts against the other end of the bearing through groove 11.

[0045] Specifically, this embodiment prevents the first arc bearing 3 and the second arc bearing 4 from falling off from the other side of the base 1 during rotation by adding a first limiting step 33 and a second limiting step 43, thus ensuring the stability and reliability of the photovoltaic tracking system.

[0046] Please see Figures 1 to 4As shown, the first arc-shaped bearing 3 and the first limiting step 32 are integrally formed, the second arc-shaped bearing 4 and the second limiting step 42 are integrally formed, and the first arc-shaped bearing 3 and the first limiting step 33 are separate structures. The first arc-shaped bearing 3 is connected to the first limiting step 33 by a snap-fit ​​mechanism, and the second arc-shaped bearing 4 and the second limiting step 43 are separate structures, with the second arc-shaped bearing 4 connected to the second limiting step 43 by a snap-fit ​​mechanism. The first arc-shaped bearing 3 and the second arc-shaped bearing 4 have the same structure. The end of the first arc-shaped bearing 3 facing the first limiting step 33 has a snap-fit ​​part 331 extending away from the first arc-shaped bearing 3. The first limiting step 33 has a snap-fit ​​groove 332, and a guide slope matching the snap-fit ​​part 331 is provided in the snap-fit ​​groove 332. The first arc-shaped bearing 3 and the second arc-shaped bearing 4 can be injection molded to form an integral structure.

[0047] Specifically, in this embodiment, the first arc-shaped bearing 3 and the second arc-shaped bearing 4 are connected to the first limiting step 33 and the second limiting step 43 respectively by means of a snap-fit ​​mechanism. This facilitates the assembly of the inner ring of the plastic bearing, reduces the installation difficulty of the photovoltaic main shaft 2, improves the installation efficiency of the photovoltaic main shaft 2, and makes it less likely for the first limiting step 33 and the second limiting step 43 to fall off. This solves the problem of loosening and failure of traditional bolt connections and ensures the stability and reliability of the photovoltaic tracking system.

[0048] As an optional embodiment two, please refer to Figure 5 As shown, to further improve the service life of the mounting components for the photovoltaic tracking bracket, the first arc-shaped bearing 3 and the first limiting step 32 are integrally molded, while the first arc-shaped bearing 3 and the first limiting step 33 are separate structures. The first arc-shaped bearing 3 is connected to the first limiting step 33 by a snap-fit ​​mechanism. The second arc-shaped bearing 4, the second limiting step 42, and the second limiting step 43 are integrally molded. The first arc-shaped bearing 3 and the second arc-shaped bearing 4 can be injection molded to form an integral structure; the snap-fit ​​mechanism of the first arc-shaped bearing 3 can be the same as that in Embodiment 1.

[0049] Specifically, this embodiment improves the structural strength of the second arc bearing 4 by designing the second arc bearing 4, the second limiting step 1 42, and the second limiting step 2 43 as an integral structure, enabling the second arc bearing 4 to withstand more loads and further improving the service life of the installation components for the photovoltaic tracking bracket.

[0050] As an optional embodiment three, please refer to Figures 6 to 7As shown, in order to facilitate the assembly of the inner ring of the plastic bearing, the first arc bearing 3 and the first limiting step 32 adopt an integral molding structure, the second arc bearing 4 adopts an integral molding structure with the second limiting step 42 and the second limiting step 43, the first arc bearing 3 and the first limiting step 33 adopt a separate structure, and the first limiting step 33 is connected to the first arc bearing 3 by bolt connection.

[0051] The first limiting step 33 includes a stop plate 301, a sheet metal stop plate 302, a limiting bolt 303, and a limiting nut 304. One end of the stop plate 301 abuts against the first arc-shaped bearing 3, and the other end of the sheet metal stop plate 302 abuts against the stop plate 301. The limiting bolt 303 passes through the sheet metal stop plate 302, the stop plate 301, the first arc-shaped bearing 3, and the first limiting step 32 in sequence, and is connected to the limiting nut 304 by a threaded connection. The stop plate 301 is fan-shaped and can be made of plastic. The sheet metal stop plate 302 has a through-hole, the stop plate 301 has a through-hole, and the first arc-shaped bearing 3 has a through-hole. The limiting bolt 303 passes through the sheet metal through-hole, the stop plate through-hole, and the inner ring through-hole in sequence. The lower end of the stop plate 301 abuts against the outer wall of the photovoltaic main shaft 2.

[0052] Specifically, in this embodiment, the limiting bolt 303 connects the second arc-shaped bearing 4 and the first limiting step 33, simplifying the installation structure, facilitating the assembly of the inner ring of the plastic bearing, reducing the installation difficulty of the photovoltaic spindle 2, and improving the installation efficiency of the photovoltaic spindle 2. Furthermore, the photovoltaic spindle 2 adopts an octahedral structure, with the baffle plate 301 abutting against one end face of the photovoltaic spindle 2, reducing the deflection force generated by the contact between the first limiting step 33 and the second limiting step 43, causing the limiting bolt 303 to rotate under force, preventing the limiting bolt 303 from failing due to rotation, and improving the service life of the installation components for the photovoltaic tracking bracket. At the same time, the baffle plate 301, sheet metal baffle 302, limiting bolt 303, and limiting nut 304 have fewer structural components and less weight, which helps to reduce the installation cost of photovoltaics.

[0053] As an optional embodiment four, please refer to Figures 8 to 9As shown, the mounting assembly for the photovoltaic tracking bracket also includes two symmetrically arranged limiting members 5. The first arc-shaped bearing 3 and the first limiting step 32 are integrally formed, and the second arc-shaped bearing 4 and the second limiting step 42 are integrally formed. The limiting members 5 are fixedly connected to the photovoltaic main shaft 2. The end of the limiting member 5 facing the base 1 is provided with an abutment part 51, which abuts against the first limiting step 32 and the second limiting step 42, and fixes the first limiting step 32 and the second limiting step 42. The limiting members 5 are made of metal, such as high-strength metal materials like aluminum alloy or stainless steel; the limiting members 5 and the abutment part 51 are integrally formed, for example, by stamping.

[0054] Specifically, this embodiment improves the structure of the limiting member 5 so that the limiting member 5 can fully abut against the first limiting step 32 and the second limiting step 42, ensuring the stability and reliability of the bearing inner ring and improving the service life of the installation components for the photovoltaic tracking bracket. At the same time, the limiting member 5 adopts an integral molding structure, which can be manufactured by stamping process, resulting in lower manufacturing cost and facilitating the assembly of the limiting member 5.

[0055] As an optional embodiment five, please refer to Figures 10 to 11 As shown, the base 1 includes an upper base 101 and a lower base 102 connected to each other. The upper base 101 has an upper arc-shaped portion 1011, and upper connecting ears 1012 extending outward on both sides of the upper arc-shaped portion 1011. The lower base 102 has a lower arc-shaped portion 1021, and lower connecting ears 1022 extending outward on both sides of the lower arc-shaped portion 1021. The upper connecting ears 1012 and the lower connecting ears 1022 are fixedly connected by bolts. The upper arc-shaped portion 1011 and the lower arc-shaped portion 1021 combine to form a bearing through groove 11. The upper base 101 and the lower base 102 are made of metal, such as high-strength metal materials like aluminum alloy; the upper base 101 and the lower base 102 adopt an integrally formed structure, such as through a stamping process.

[0056] Specifically, this embodiment splits the base 1 into an upper base 101 and a lower base 102, enabling the photovoltaic spindle 2 to be quickly assembled. This changes the existing side-plug assembly method, reduces the installation difficulty of the photovoltaic spindle 2, and improves the installation efficiency of the photovoltaic spindle 2.

[0057] As an optional embodiment six, please refer to Figures 12 to 13As shown, a through mounting groove 12 is formed on the base 1 along the bearing through groove 11. A lower base bolt hole 13, communicating with the mounting groove 12, is formed vertically at the bottom of the base 1. Two bolt fixing clips 14 are provided on the mounting groove 12 along the bearing through groove 11. The bolt fixing clips 14 are symmetrically arranged with respect to the lower base bolt hole 13. A fixing nut 15 is inserted between the two bolt fixing clips 14. A fixing bolt 16 is inserted into the bottom of the lower base bolt hole 13. The fixing bolt 16 and the fixing nut 15 are fixedly connected by a threaded connection. Specifically, the fixing bolt 16 is inserted into the lower base bolt hole 13 from below, and the fixing nut 15 is inserted from one side of the mounting groove 12. The bolt fixing clips 14 abut against the side wall of the fixing nut 15 on the base 1, restricting the rotation of the fixing nut 15, thus changing the existing installation method of the base 1.

[0058] Specifically, in this embodiment, the fixing bolt 16 is screwed into the fixing nut 15 from bottom to top through the lower base bolt hole 13 of the base 1. The fixing nut 15 automatically fixes the device, and only the fixing bolt 16 needs to be tightened. This simplifies the installation process, reduces the installation time of the base 1, and improves the installation efficiency of the photovoltaic tracking bracket installation components.

[0059] As an optional embodiment, please refer to Figures 1 to 14 As shown, the mounting assembly for the photovoltaic tracking bracket also includes a support base 6, which is connected to the base 1 via fixing bolts 16. The support base 6 includes a support portion 61 connected to the base 1. The support portion 61 is rectangular, with an upwardly extending long-side limiting portion 62 on its long side and a downwardly extending short-side connecting portion 63 on its short side. The long-side limiting portion 62, the short-side connecting portion 63, and the support portion 61 are integrally formed. The short-side connecting portion 63 has mounting holes, which are connected to the column via bolts.

[0060] Specifically, in this embodiment, the long side limiting part 62 can improve the structural rigidity of the support part 61, and the short side connecting part 63 is connected to the external column, so that the lower part of the base 1 has a certain operating space, which facilitates the assembly of the fixing bolts 16.

[0061] In summary, this utility model changes the installation method of the photovoltaic main shaft 2 by splitting the photovoltaic plastic bearing into a first arc bearing 3 and a second arc bearing 4, reducing the installation difficulty of the photovoltaic main shaft 2 and improving the installation efficiency of the photovoltaic main shaft 2. At the same time, the photovoltaic main shaft 2 adopts an octagonal prism structure, which can effectively improve the structural strength of the photovoltaic main shaft 2, the first arc bearing 3 and the second arc bearing 4, and increase the service life of the photovoltaic main shaft 2 and the plastic bearing. In addition, by adding a first limiting step 32, a second limiting step 42, a first limiting step 33 and a second limiting step 43, the first arc bearing 3 and the second arc bearing 4 are prevented from falling off from both sides of the base 1 during rotation, thereby improving the service life of the installation components for the photovoltaic tracking bracket.
