Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and in particular relates to a flexible tracking bracket bearing installation structure. Background Technology

[0002] With the continuous maturation of technology and the gradual reduction of costs, flexible photovoltaic tracking brackets have been widely used in many scenarios such as mountainous agricultural-photovoltaic integration, fishery-photovoltaic integration, coastal mudflats, desertification control, and industrial and commercial distributed generation. They have formed a trend of replacing traditional fixed brackets in most scenarios. In the future, with further technological innovation and the continuous growth of market demand, flexible photovoltaic tracking brackets are expected to be more widely used and developed.

[0003] Generally, rigid tracking supports only bear negligible axial forces. However, when a flexible tracking support loses its rigid support, all the forces fall on the two side columns and the slewing support structure of the inclined beam. The rotating shaft, bearings, and support seats must bear the weight of the frame itself, as well as external wind and snow loads. At the same time, because the steel strands are flexible, they need to be pre-tensioned, so the structure must also withstand the tensile force brought about by the pre-tensioning of the steel strands. Therefore, due to its structure and characteristics, the flexible tracking support has extremely high requirements for the force between the side rotating inclined beam and the mounting seat on the column. It must withstand the high-strength pre-tensioning force of the steel strands and meet the various loads of the usage scenario. Designing a simple and durable load-bearing structure is technically challenging and is a problem that urgently needs to be solved. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a flexible tracking bracket bearing mounting structure that is structurally reasonable, has good stability, and allows for flexible rotation.

[0006] A flexible tracking bracket bearing mounting structure includes a column, a support base fixed to the top of the column, a thrust bearing assembly at one end of the support base, and a rotating beam rotatably connected to the support base via the thrust bearing assembly.

Two mounting seats are fixedly connected to the end of the base plate away from the thrust bearing assembly. The two mounting seats are spaced apart and a baffle is fixedly connected between the two mounting seats. The lower end of the baffle is fixedly connected to the base plate. The base plate, the baffle, and the two mounting seats together form a sliding bearing housing. A sliding bearing assembly is installed inside the sliding bearing housing.

[0012] Further optimization: The sliding bearing assembly includes a sliding bearing, which is installed in a sliding bearing housing. Fasteners are provided above the sliding bearing and are detachably fixed to the mounting base by bolts.

Detailed Implementation

[0033] Example 1:

[0034] like Figure 1-7 As shown, a flexible tracking bracket bearing mounting structure includes a column 1, a support base 2 fixedly connected to the top of the column 1, a thrust bearing assembly 3 provided at one end of the support base 2, and a rotating beam 4 rotatably connected to the support base 2 through the thrust bearing assembly 3.

[0035] With this design, the thrust bearing assembly 3 can not only support and rotate the rotating beam 4, but also withstand the axial and radial loads and torque transmitted from the rotating beam 4. Through the reasonable design of the thrust bearing assembly 3, a stable support is formed for the rotating beam 4, and the flexibility of the rotating beam 4's reciprocating swing is improved.

[0036] The thrust bearing assembly 3 includes a thrust bearing housing 301. A second flange 3011 is provided at one end of the thrust bearing housing 301 near the support base 2. The second flange 3011 is fixedly connected to the support base 2. A bearing mounting cavity 3012 is provided inside the thrust bearing housing 301. A thrust bearing 303 is installed in the bearing mounting cavity 3012. A stabilizing shaft 302 is rotatably connected to the thrust bearing housing 301 through the thrust bearing 303. The outer ring of the thrust bearing 303 is fitted inside the thrust bearing housing 301. The inner ring of the thrust bearing 303 is fitted on the stabilizing shaft 302. A third flange 3021 is fixedly connected to one end of the stabilizing shaft 302 near the rotating beam 4. The third flange 3021 is fixedly connected to the rotating beam 4.

[0037] The thrust bearing 303 is a thrust roller bearing, which improves the axial load capacity of the structure and thus improves the ability to withstand overturning moments.

[0038] An axial limiting block 307 is integrally fixed to the side of the third flange 3021 near the thrust bearing 303, and a round nut 306 is provided on the side of the second flange 3011 away from the thrust bearing 303. The round nut 306 is threadedly connected to the stabilizing shaft 302.

[0039] With this design, rotating the round nut 306 brings the third flange 3021 closer to the thrust bearing housing 301, thereby bringing the inner and outer rings of the thrust bearing 303 closer together, thus achieving effective installation of the thrust bearing 303.

[0040] A first oil seal 304 is provided between the thrust bearing housing 301 and the axial limiting block 307, and a second oil seal 305 is provided between the second flange 3011 and the stabilizing shaft 302.

[0041] This design prevents dust, sand, and other impurities from entering the thrust bearing 303 and causing wear, thus affecting its service life.

[0042] The support base 2 includes a base plate 203, which is fixedly connected to the column 1. A support plate 201 is fixedly connected to one end of the base plate 203 near the thrust bearing assembly 3. The support plate 201 is detachably fixed to the second flange 3011 by bolts.

[0043] Two mounting seats 204 are fixedly connected to one end of the base plate 203 away from the thrust bearing assembly 3. The two mounting seats 204 are symmetrically arranged at a certain distance. A baffle 205 is fixedly connected between the two mounting seats 204. The lower end of the baffle 205 is fixedly connected to the base plate 203. The base plate 203, the baffle 205 and the two mounting seats 204 together form a sliding bearing housing 206. A sliding bearing assembly 5 is provided inside the sliding bearing housing 206.

[0044] Two vertical plates 202 are fixedly connected between the support plate 201 and the baffle 205. The two vertical plates 202 are arranged in parallel at a certain distance. The lower end of the vertical plate 202 is fixedly connected to the base plate 203, thereby improving the overall strength of the support base 2.

[0045] The rotating beam 4 includes a rotating beam frame 402. A first flange 401 is fixedly connected to the side of the rotating beam frame 402 near the thrust bearing assembly 3. The first flange 401 is detachably fixed to a third flange 3021 by bolts.

[0046] The rotating beam frame 402 is a single beam structure, made of rectangular tube. Both ends of the rotating beam frame 402 are fixed with mounting blocks for installing steel strands.

[0047] Figure 1 The direction of the middle arrow indicates the direction of tension of the steel strand, which is the direction of force on the rotating beam frame 402.

[0048] The sliding bearing assembly 5 includes a sliding bearing 501, which is installed in the sliding bearing housing 206. A fastener 502 is provided above the sliding bearing 501. The fastener 502 is detachably fixed to the mounting base 204 by bolts, thereby enabling the sliding bearing 501 to be securely installed in the sliding bearing housing 206.

[0049] The end of the stabilizing shaft 302 away from the rotating beam 4 extends into the interior of the sliding bearing 501 and is rotatably connected to it. The outer surface of the stabilizing shaft 302 matches the inner hole size of the sliding bearing 501, thus serving to stabilize the thrust bearing assembly 3.

[0050] This design allows the sliding bearing 501 to provide further support to the stabilizing shaft 302, thereby increasing the stability of the rotating beam 4.

[0051] Example 2:

[0052] like Figure 8 and 9 As shown, the rotating beam 4 includes a rotating beam frame 402. Unlike the structure in Embodiment 1 above, the rotating beam frame 402 is a frame structure, which is spliced ​​together from rectangular tubes and angle steel. A first flange 401 and an auxiliary support shaft 403 are fixedly connected to the rotating beam frame 402. The first flange 401 is detachably fixed to the third flange 3021 by bolts. The auxiliary support shaft 403 is rotatably connected to the sliding bearing 501.

[0053] With this design, part of the load of the thrust bearing 303 is distributed to the rotating beam 4 through the frame structure. At the same time, the stabilizing shaft 302 is no longer connected to the sliding bearing 501. An auxiliary support shaft 403 is welded to the other side of the rotating beam frame 402 to replace the load of the stabilizing shaft 302.

[0054] Both ends of the rotating beam frame 402 are fixed with mounting blocks for installing steel strands.

[0055] Figure 8 The direction of the middle arrow indicates the direction of tension of the steel strand, which is the direction of force on the rotating beam frame 402.

[0056] Example 3:

[0057] like Figure 10-12 As shown, the thrust bearing assembly 3 includes a thrust bearing housing 301. A second flange 3011 is fixedly connected to one end of the thrust bearing housing 301 near the support base 2. The second flange 3011 is fixedly connected to the support base 2. A bearing mounting cavity 3012 is provided inside the thrust bearing housing 301. A thrust bearing 303 is installed in the bearing mounting cavity 3012. A stabilizing shaft 302 is rotatably connected to the thrust bearing housing 301 through the thrust bearing 303. The outer ring of the thrust bearing 303 is fitted inside the thrust bearing housing 301, and the inner ring of the thrust bearing 303 is fitted on the stabilizing shaft 302. A third flange 3021 is fixedly connected to one end of the stabilizing shaft 302 near the rotating beam 4. The third flange 3021 is fixedly connected to the rotating beam 4.

[0058] The second flange 3011 has a nut mounting cavity 3013. A retaining ring 3014 is provided between the nut mounting cavity 3013 and the bearing mounting cavity 3012. The retaining ring 3014 is integrally fixed to the second flange 3011.

[0059] The stabilizer shaft 302 is an integral three-section structure, including a sealing section 3022, a bearing mounting section 3023 and a threaded section 3024. The sealing section 3022 is fixedly connected to the third flange 3021. The sealing section 3022 and the bearing mounting section 3023 are located in the bearing mounting cavity 3012, and the threaded section 3024 is located in the nut mounting cavity 3013.

[0060] The inner ring of the thrust bearing 303 is fitted onto the bearing mounting section 3023. A round nut 306 is provided on the side of the retaining ring 3014 away from the thrust bearing 303. The round nut 306 is threadedly connected to the threaded section 3024.

[0061] With this design, the thrust bearing assembly 3 has no protruding parts. By using a stretching tool to create a certain gap between the rotating beam 4 and the support base 2, the thrust bearing assembly 3 can be removed as a whole, which greatly facilitates the installation and disassembly of the thrust bearing assembly 3.

[0062] A first oil seal 304 is provided between the thrust bearing housing 301 and the sealing section 3022, and a second oil seal 305 is provided between the retaining ring 3014 and the bearing mounting section 3023.

[0063] This design prevents dust, sand, and other impurities from entering the thrust bearing 303 and causing wear, thus affecting its service life.

[0064] Example 4:

[0065] like Figure 13 As shown, unlike the integral bearing with a central opening in embodiments 1-3, the sliding bearing 501 in this embodiment is a bearing with two halves and an arc-shaped groove, and the two halves of the bearing are used together.

[0066] This design makes the installation and disassembly of the rotating beam 4 more convenient.

[0067] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
