Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic tracking brackets, and in particular to a photovoltaic tracking synchronization mechanism with flexible transmission. Background Art

[0002] At present, the mounting brackets used for solar photovoltaic modules mainly include fixed type and tracking type. Tracking brackets are further divided into single-axis tracking brackets and dual-axis tracking brackets.

[0003] Usually, the solar tracking bracket is driven by one or more reduction mechanisms, which rotate the main shaft to drive the photovoltaic module to rotate. The reduction mechanisms all have a self-locking function, which can lock the photovoltaic module from rotating when not in operation.

[0004] The speed reduction mechanisms with self-locking function currently used are mostly worm gear speed reduction mechanisms. When a single-row solar tracking bracket is driven by multiple speed reduction mechanisms, a transmission shaft is used to drive each speed reduction mechanism synchronously. However, the input direction of the worm gear is 90° to the output direction of the worm gear. Therefore, when multiple speed reduction mechanisms are driven synchronously, a reversing system must be added to the speed reduction mechanism so that the transmission shaft can be in the same direction as the main shaft; and the transmission shaft transmission has high requirements on the concentricity of the input shafts of the speed reduction mechanisms on both sides, so universal joints are added on both sides of the transmission shaft to ensure that the transmission shaft can smoothly transmit torque. However, the added reversing system and universal joint will not only increase the cost, but also make the installation more difficult. Utility Model Content

[0007] The transmission member is used to be coaxially connected to the input shaft of the transmission mechanism of the photovoltaic tracking bracket, and is used to drive the input shaft to rotate;

[0008] The transmission member is provided with a plurality of transmission ends around its rotation axis, and the corresponding transmission ends between two adjacent transmission members are connected by the transmission rope;

[0009] The multiple transmission ends are staggered along the direction of the rotation axis of the transmission member, and the projections of the multiple transmission ends along the direction of the rotation axis of the transmission member are distributed in a circle around the rotation axis.

[0010] By adopting the above technical scheme, the transmission member is coaxially connected with the input shaft of the transmission mechanism, and a plurality of transmission ends are arranged around the rotation axis of the transmission member to realize reversing transmission, which has a simple structure and low cost. By connecting the transmission rope and the transmission member, flexible transmission is realized, and there is no need to use a universal joint, which is convenient for installation and reduces the concentricity requirements for the input shafts of adjacent transmission mechanisms, further facilitating the installation of the photovoltaic tracking bracket and reducing the cost.

[0055] The photovoltaic tracking bracket comprises a main shaft 1 and a driving assembly for driving the main shaft 1 to rotate around its axis to achieve tracking of the sun.

[0056] The photovoltaic tracking bracket also includes a plurality of beams 2 installed along the length direction of the main shaft 1, and photovoltaic modules can be installed on the beams 2. In order to improve the connection stability between the main shaft 1 and the beams 2, the bracket usually also uses diagonal braces 3 to form a triangular structure with the beams 2 and connect to the main shaft 1, and pads are provided between the beams 2 and the main shaft 1, and between the diagonal braces 3 and the main shaft 1.

[0057] The photovoltaic tracking bracket also includes a supporting column 4 and a driving column 6. A mounting assembly 5 is arranged at the top of the supporting column 4. The main shaft 1 is arranged on the supporting column 4 through the mounting assembly 5, and can be rotated relative to the supporting column 4 through the mounting assembly 5. The transmission mechanism 100 is installed on the driving column 6.

[0059] A second mounting seat 61 is disposed at the top end of the driving column 6 , and the transmission mechanism 100 is mounted on the second mounting seat 61 .

[0060] The driving assembly includes a plurality of transmission mechanisms 100 and a driving member. At least one input shaft 110 of the plurality of transmission mechanisms 100 is drivingly connected to the driving member, and the driving member may be a motor.

[0061] Typically, the transmission mechanism 100 includes an input shaft 110, a driven end 120 fixedly connected to the main shaft 1, and a first transmission member that transmission-connects the input shaft 110 and the driven end 120, thereby transmitting the driving force of the driving member to the main shaft 1 and realizing the rotation of the main shaft 1 around its axis.

[0062] In one embodiment, the transmission mechanism 100 is a reducer, so as to achieve slow rotation of the main shaft 1 and improve its rotation stability. Further, the transmission mechanism 100 is a worm gear reducer, and its input shaft 110 and the motor can be connected to the two ends of the worm respectively, so as to control the cost of the reducer, and at this time, after the transmission mechanism 100 and the main shaft 1 are installed, its input shaft 110 is located on the side of the main shaft 1.

[0063] It is understandable that, in order to achieve tracking position locking, the transmission mechanism 100 may have a self-locking function.

[0064] In order to achieve synchronous rotation of multiple transmission mechanisms 100 and avoid the multiple transmission mechanisms 100 being out of sync, which causes the main shaft 1 to twist on its axis, an embodiment of the present application provides a flexible transmission photovoltaic tracking synchronization mechanism, which is used to be connected to the input shaft 110 of the multiple transmission mechanisms 100 of the photovoltaic tracking bracket to achieve synchronous rotation of the multiple transmission mechanisms 100.

The installation is convenient, and the concentricity requirement for the input shaft 110 of the adjacent transmission mechanism 100 is reduced, which further facilitates the installation of the photovoltaic tracking bracket and reduces the cost. At the same time, the flatness requirement for the installation terrain is low, and the terrain adaptability of the photovoltaic tracking bracket is improved. In addition, by designing the plurality of transmission ends 201 of the transmission member 200, the transmission stability and reliability are improved, thereby ensuring the synchronous rotation of the plurality of transmission mechanisms 100 of the photovoltaic tracking bracket, thereby improving the tracking stability and reliability of the photovoltaic tracking bracket.

[0079] The first groove 511 and the corresponding second groove 521 form a limiting hole, so that the size of the limiting hole can be adjusted by adjusting the stacking position of the first limiting plate 510 and the second limiting plate 520. This is suitable for different models of transmission ropes 400 and different limiting requirements, improves the versatility of the limiting assembly 500, and facilitates installation.
