Description

Technical Field

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

[0002] In the current photovoltaic tracking system, the main beam and bearing structure of the tracker generally adopts a combination design of square tubes and square detachable bearings. The main feature of this structure is that the main beam and the bearing are fixed together by inlaying. Although it achieves structural stability to a certain extent, it exposes some problems during the actual installation process.

[0003] First, the original intention of the square removable bearing design is to facilitate disassembly and assembly, but in actual operation, due to the limitations of the structural design, the disassembly and assembly of the bearing is not as quick and convenient as expected. This leads to a relatively limited fixing effect on the square tube during installation and maintenance, and it is difficult to ensure that the square tube can resist the anti-slip effect of torque after being fixed. This not only affects the overall stability of the tracker, but also increases safety hazards.

[0004] Secondly, after long-term use of this structure, the bearings tend to wear out. Since the square detachable bearings are inconvenient to disassemble and assemble, once the bearings are severely worn, they cannot be quickly replaced. This will not only cause the bearings to wear further, but also increase the resistance of the overall operation, thereby increasing the mechanical energy loss in subsequent use. This not only affects the operating efficiency of the photovoltaic tracking system, but also increases energy waste.

[0005] In addition, when the bearing needs to be replaced, the square tube needs to be disassembled. This process is not only time-consuming and labor-intensive, but may also cause damage to other parts of the tracker. Therefore, the existing square tube with square detachable bearing structure has certain limitations in the application of photovoltaic tracking systems and needs to be improved and optimized.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] A photovoltaic tracking system main beam half bearing, comprising a supporting component 1, a half bearing component 2 and a fixing component 3;

[0051] The support assembly 1 comprises a bearing seat 101, the bearing seat 101 is annular, and an annular through hole 100 is formed in the bearing seat 101;

[0052] The half-bearing assembly 2 comprises at least one pair of symmetrically arranged half-bearing bodies 201, and the facing surfaces of the pair of half-bearing bodies 201 are centrally formed with a clamping recess, and the clamping recess is used to clamp on the outer side of the main beam of the photovoltaic tracking system;

[0053] At least one side of a pair of half bearing bodies 201 is provided with the fixing assembly 3 , and the fixing assembly 3 is used to rotatably install the half bearing body 201 in the annular through hole 100 .

[0054] The present application supports the main beam in the photovoltaic tracking system through the supporting component 1, clamps the half-bearing component 2 on the outside of the main beam, and fixes the position of the half-bearing component 2 through the fixing component 3, so that the main beam can rotate in the supporting component 1. Specifically, the bearing seat 101 is sleeved on the main beam of the tracker in the photovoltaic tracking system (hereinafter referred to as the main beam) through the annular through hole 100, and then at least one pair of half-bearing bodies 201 are clamped on the outside of the main beam, and the fixing component 3 is used to complete the fixing of several half-bearing bodies 201, so that they are symmetrically installed in the annular through hole 100 of the bearing seat 101. After the fixing is completed, the half-bearing component 2 is rotatably set in the bearing seat 101, so that it rotates synchronously with the bearing seat when the main beam rotates.

[0055] Further explanation, since the several half-bearing bodies 201 of the half-bearing assembly 2 adopt a half-symmetrical design, during maintenance or disassembly, the specific half-bearing body 201 can be disassembled and replaced by releasing the fixation of the fixing assembly 3 on the several half-bearing bodies 201 and pulling them out, and the main beam can be fixed in conjunction with the clamping recesses formed between the several half-bearing bodies 201 to ensure the anti-slip effect of the torque after the main beam is fixed.

Timely maintenance can reduce the overall operation resistance and reduce the mechanical energy loss in subsequent use.

[0056] Further explanation, several half-bearing bodies 201 are fixed on the main beam through the fixing component 3, and separate fixing measures are adopted with the bearing seat 101, so that the interaction frequency with the bearing seat 101 is reduced during the disassembly and installation process, which makes it easier to disassemble and assemble the half-bearing body 101, saving time and effort.
