Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic tracking systems, in particular to a self-locking bearing for a main beam of a photovoltaic tracking system. Background Art

[0002] The main beam and bearing structure design of photovoltaic trackers currently on the market, while ensuring the stable connection between the main beam and the bearing, often does not clearly limit the rotation range of the main beam. Although this design gives the tracker a certain degree of flexibility, allowing the main beam to rotate accordingly with the movement of the sun, it may also bring some potential problems.

[0003] First, there is no limit on the rotation range of the main beam, which means that in actual operation, the main beam may exceed its optimal rotation range due to external factors. This may not only reduce the working efficiency of the tracker, but also cause unnecessary wear on key components such as bearings, thereby shortening their service life.

[0004] Secondly, the unlimited rotation range of the main beam may also increase the complexity of the system. During the operation of the tracker, the rotation angle and speed of the main beam need to be precisely controlled to achieve efficient tracking of the sun. If the rotation range of the main beam is too large, the control system needs to deal with more variables and uncertainties, which increases the complexity of the system and the possibility of error.

[0034] like Figure 1-3 As shown, a self-locking bearing for the main beam of a photovoltaic tracking system includes a supporting component 1, a bearing component 2 and a self-locking component 3;

[0035] The support assembly 1 comprises a bearing seat 11, and the bearing seat 11 is semi-annular;

[0036] The self-locking assembly 3 includes a first self-locking body 31, a second self-locking body 32 and a first fixing member 33;

[0037] The first self-locking body 31 is semi-annular, and is installed above the bearing seat 11, and an annular limiting space is formed between the first self-locking body 31 and the facing surfaces of the bearing seat 11 through the first fixing member 33;

[0038] The bearing assembly 2 is rotatably installed in the annular limiting space;

[0039] The bearing assembly 2 includes a first bearing body 21 and a second bearing body 22. The first bearing body 21 is installed above the second bearing body 22. The facing surfaces of the first bearing body 21 and the second bearing body 22 are both centrally formed with a clamping recess 20. The clamping recess 20 is used to clamp the outer side of the main beam 4 in the photovoltaic tracking system.

[0040] The back side of the first bearing body 21 is provided with a mounting recess 210 , and the mounting recess 210 is provided with the second self-locking body 32 . The facing surfaces of the first self-locking body 31 and the second self-locking body 32 form a limiting rotation portion 34 , and the limiting rotation portion 34 is used to limit the rotation range of the main beam 4 .

[0041] When in use, first clamp the clamping notches 20 of the first bearing body 21 and the second bearing body 22 on the outside of the main beam 4, then install the second bearing body 22 above the bearing seat 11, and then place the second self-locking body 32 in the installation notch 210 on the back of the first bearing body 21, then snap the first self-locking body 31 with the bearing seat 11, and form an annular limiting space after self-locking through the first fixing member 33, so that the first bearing member and the second bearing member are engaged on the main beam 4, forming a radial limit for the main beam 4. Moreover, the limiting rotation parts 34 between the first self-locking body 31 and the second self-locking body 32 cooperate with each other to limit the rotation range of the main beam 4.

[0042] In summary, the present application realizes limited rotation and stable support of the main beam 4 through the cooperation of the supporting assembly 1, the bearing assembly 2 and the self-locking assembly 3, thereby ensuring the stability and tracking accuracy of the photovoltaic tracking system during operation.

[0043] To further explain, the limiting rotation portion 34 includes a first arc-shaped rack 341 and a second arc-shaped rack 342 meshing with each other, and the first arc-shaped rack 341 and the second arc-shaped rack 342 are respectively arranged along the facing surfaces of the first self-locking body 31 and the second self-locking body 32.

[0044] To further explain, the arc length of the first arc-shaped rack 341 is greater than the arc length of the second arc-shaped rack 342 .

[0045] First, the first arc-shaped rack 341 and the second arc-shaped rack 342 are meshed with each other to achieve a firm connection between the first self-locking body 31 and the second self-locking body 32. This meshing design not only improves the stability of the connection, but also enhances the overall strength of the structure, making the entire self-locking assembly 3 less likely to loosen or deform when subjected to external forces.

[0046] Secondly, the arc length of the first arc-shaped rack 341 is greater than the arc length of the second arc-shaped rack 342. This design enables the first arc-shaped rack 341 to completely cover and wrap the second arc-shaped rack 342 during the meshing process, thereby forming a tighter connection. This tight connection not only improves the self-locking effect, but also reduces the gap and looseness problems caused by loose connection.

[0047] In general, the design of the limiting rotation part 34 achieves a firm connection between the first self-locking body 31 and the second self-locking body 32 through the meshing and arc length difference of the first arc-shaped rack 341 and the second arc-shaped rack 342, thereby improving the stability and reliability of the entire self-locking bearing.

[0048] To further explain, the self-locking component 3 also includes two hook springs 35, one hook end of the two hook springs 35 is respectively hung on the two ends of the bottom of the second self-locking body 32, and the other hook end of the two hook springs 35 is hung on the two ends in the installation recess 210.

[0049] Since the two ends of the hook spring 35 are respectively hung on the bottom of the second self-locking body 32 and in the mounting recess 210, this connection method provides an additional support and fixing effect for the second self-locking body 32, thereby enhancing the stability of the entire structure. Secondly, the hook spring 35 has a certain elasticity. When the main beam 4 needs to be restored to the original or preset position after rotation, the hook spring 35 can use its elastic force to help the self-locking component 3 automatically return to the original or preset position, which greatly simplifies the operation process and improves the convenience of use.

[0050] To further illustrate, both ends of the bearing seat 11 extend outward to form a first mounting portion 13, and the first mounting portion 13 is provided with a first mounting hole;

[0051] Both ends of the first self-locking body 31 extend outward to form a second mounting portion 311, and the second mounting portion 311 is provided with a second mounting hole;

[0052] The first fixing member 33 is provided with the second mounting hole and the first mounting hole in sequence from top to bottom.

[0053] For further explanation, a reinforcing rib 14 is provided at the bottom of the first mounting portion 13 , and two ends of the reinforcing rib 14 are respectively fixedly connected to the bottom of the first mounting portion 13 and the outer annular surface of the bearing seat 11 .

[0054] Specifically, the first mounting portion 13 and the second mounting portion 311 can ensure a tight and accurate connection between the first self-locking body 31 and the bearing seat 11, and the addition of the reinforcing ribs 14 can significantly improve the structural strength of the first mounting portion 13 and the second mounting portion 311, reducing the risk of structural deformation and damage.

[0055] To further explain, a supporting seat 12 is provided at the bottom end of the bearing seat 11, and the supporting seat 12 is a U-shaped seat. Two groups of strip connecting holes for fixing the supporting seat 12 are provided at intervals along the length direction at the bottom of the U-shaped seat, and a second fixing member 15 is passed through the strip connecting hole.

[0056] To further explain, the cross section of the supporting seat 12 is a combination of a triangle and an arc.

[0057] It is known that the triangle is a stable geometric shape, so it can provide excellent support and stability in the design of the support seat 12. Combined with the arc design, the force can be further dispersed and balanced, making the support seat 12 more stable when bearing the weight and force from the main beam 4 of the photovoltaic tracking system, reducing the possibility of deformation and displacement.

[0058] To further explain, the front side surface and the rear side surface of the first bearing body 21 and the second bearing body 22 are both protruded with an arc plate 23 , and the arc plate 23 abuts against the edge of the bearing seat 11 .

[0059] First, the design of the arc plate 23 enhances the connection stability between the first bearing body 21 and the second bearing body 22 and the bearing seat 11. By abutting the arc plate 23 against the edge of the bearing seat, the loosening or displacement of the bearing body during operation can be effectively prevented, thereby improving the stability and reliability of the entire bearing structure.

[0060] Secondly, the design of the arc plate also makes the installation and removal process of the bearing easier. During installation, the first bearing body 21 and the second bearing body 22 can be quickly positioned and fixed with the bearing seat through the arc plate, reducing installation time and cost.

[0061] To further explain, the clamping recess 20 is provided with a plastic bushing 201, and the interior of the plastic bushing 201 has a plurality of compartments arranged separately. In a specific implementation, the arrangement of the plastic bushing 201 can be implemented in a variety of embodiments. For example, Figure 3 As shown, in order to reduce the amount of engineering plastics used while ensuring the supporting performance of the plastic bearing 201, the interior of the plastic bearing 201 has a plurality of separated chambers.

[0062] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
