Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic support technical field, concretely is a kind of adjustable angle photovoltaic support. BACKGROUND

[0002] Traditional photovoltaic support mostly adopts fixed angle installation mode. Since the position of the sun in the sky will change significantly with time and season, the fixed angle photovoltaic panel cannot always maintain the best incident angle with the sunlight. For example, in the morning and evening, when the solar elevation angle is low, the fixed angle photovoltaic panel cannot fully receive sunlight, resulting in a significant reduction in power generation efficiency. In different seasons, the range of change of solar elevation angle and azimuth angle is large, and the solar elevation angle becomes smaller in winter. If the angle of the photovoltaic panel cannot be adjusted accordingly, the amount of solar radiation received will be significantly reduced. Similarly, the geographical environment and climate conditions are quite different in different regions. In some windy areas, the fixed angle photovoltaic support has a large wind resistance due to the fixed windward area, and is easily damaged by strong winds. In high-latitude areas, the problem of snow accumulation is serious in winter, and the fixed angle photovoltaic panel is not easy to slide snow, increasing the load bearing burden of the support, and even may cause the support to deform or be damaged. At the same time, the fixed angle support cannot be flexibly adjusted according to the local terrain conditions, and when installed in complex terrain such as mountains and hills, it is difficult to ensure that each photovoltaic panel can obtain good lighting conditions.

[0043] In this embodiment, the cross bar 102 and the vertical bar 103 are fixed in a cross manner on the outer frame 101, which enhances the overall strength of the support frame assembly 1, so that it can stably bear the photovoltaic panel. The inclined bars 104 are cross-connected to form an "X" type structure, one end of which is connected with the outer frame 101, and the other end is connected with the cross bar 102, which further disperses and bears the gravity from the photovoltaic panel and the external force such as wind force. This structure design improves the rigidity and stability of the support frame assembly 1, guarantees the safety and reliability of the photovoltaic support in use, and ensures that the photovoltaic panel can be stably supported under different environmental conditions.

[0044] Working principle:

[0045] Step one: check tools and equipment

[0046] Confirm that the handle 605 is in good condition, the connecting part 607 is not deformed or damaged, and it can tightly fit with the internal hexagonal groove 606 of the rotating shaft 603. Check the locking pin used for locking for bending, rusting and other conditions, and ensure that it can be smoothly inserted into the locking hole and the locking slot.

[0047] Check if the chain is properly tensioned, and there is no sign of falling off, breaking or serious wear. If the chain is too loose or too tight, it needs to be adjusted accordingly. If it is too loose, the chain can be tensioned by moving the second belt shaft bearing seat 604, and if it is too tight, it can be loosened appropriately.

[0048] Observe the support frame 2, support frame assembly 1 and the connection site for deformation, cracks or loose. If found abnormal, should be repaired or reinforced to ensure the overall stability of the structure of the support.

[0049] Step two: determine the adjustment needs

[0050] According to the current time, season, local latitude and longitude and photovoltaic panel power generation efficiency monitoring data and other information, calculate or query the appropriate angle of photovoltaic panel. For example, in summer, the sun's altitude angle is higher, the photovoltaic panel should be adjusted to a smaller pitch angle; winter is the opposite. At the same time, considering the surrounding environmental factors, such as buildings, trees and other obstructions, the angle is appropriately corrected.

[0051] Step three: angle adjustment operation phase

[0052] 1. Unlock operation

[0053] Check the locking assembly 7, if the locking pin is inserted into the locking disc 701 and the locking shell 702, pull it out and properly store it to ensure that the locking disc 701 can rotate freely.

[0054] 2. Manual adjustment of angle

[0055] Insert the connecting part 607 of the crank 605 into the internal hexagonal groove 606 of the rotating shaft 603, and rotate the crank 605 according to the predetermined rotation direction. The main sprocket 602 rotates with the rotating shaft 603, drives the secondary sprocket 601 to rotate through the chain, and then makes the connecting shaft 3 rotate. The connecting shaft 3 drives the connecting seat 4 and the support frame assembly 1 to change the angle.

[0056] During the rotation process, it needs to be done slowly and the angle change situation needs to be observed, and angle measuring instruments are used to assist to ensure that the adjusted angle is close to the target angle.

[0057] 3. Fine adjustment and confirmation

[0058] When close to the target angle, fine adjustment is performed. Rotate the crank 605 in small amplitude, and observe the incidence of light on the photovoltaic panel or use professional light detection equipment to ensure that the photovoltaic panel can receive sunlight to the greatest extent. After confirming that the adjusted angle meets the requirements, stop rotating the crank 605.

[0059] 4. Locking and fixing stage

[0060] According to the adjusted angle, the relative positions of the first locking hole 705 or the second locking hole 706 on the locking disc 701 and the first locking notch 707 or the second locking notch 708 on the locking shell 702 are observed. A set of closest and stable fixing is selected for locking and inserting the locking pin. The locking disc 701 and the locking shell 702 are tightly combined and cannot rotate relative to each other. The angle of the photovoltaic panel is checked again to see whether it is offset due to the locking operation. If there is a slight offset, the fine adjustment can be performed again and then locked.
