Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic installation equipment, and particularly relates to an adjustable fixing bracket for photovoltaic panels. Background Art

[0002] The photovoltaic bracket is one of the key equipment for building a photovoltaic power station; the photovoltaic bracket is divided into a fixed bracket and a tracking bracket according to whether it can track the sun's rotation. The fixed bracket can be further divided into a common fixed bracket and an adjustable fixed bracket. Although the tracking bracket can increase the power generation, it requires a power device, has low stability, and high operating costs; while the common fixed bracket has a simple structure and a low price, but its power generation efficiency is low. The adjustable fixed bracket adjusts the angle in different months or seasons to improve the power generation. However, when the current adjustable fixed bracket is adjusted, the bolts that play a fixing role need to be loosened, and then the elevation angle of the bracket is adjusted according to experience. After the adjustment is completed, the bolts are tightened again, and this operation is relatively troublesome. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and to provide an adjustable fixing bracket for photovoltaic panels.

The telescopic rods include an inner rod and an outer pipe sleeved and connected with each other. At least two first locking holes are arranged on the inner rod along the axial direction, and a second locking hole is correspondingly arranged on the outer pipe; a second connecting rod is connected between a pair of outer pipes. The second connecting rod is provided with a locking structure. The locking structure includes a movable pin, a pressure member, and a driving member. A hollow channel is arranged in the second connecting rod corresponding to the second locking hole. The movable pin can be movably arranged in the hollow channel, and has a locking position where it is inserted into the first locking hole and the second locking hole to keep the telescopic rod at the telescopic height locked and an unlocking position where it leaves the first locking hole to enable the telescopic rod to be telescopic.

The second limiting groove 1001 is arranged on the upper connecting seat 1002. The upper connecting seat 1002 and the lower connecting seat 1003 are provided with a threaded fastening assembly 11. The mating rail 406 is located between the upper connecting seat 1002 and the lower connecting seat 1003. By means of the threaded fastening assembly 11, the upper connecting seat 1002 and the lower connecting seat 1003 can be switched between clearance fit and tight fit with the mating rail 406. The limiting member 10 can be detached by means of the threaded fastening assembly 11, that is, the driving member 9 is detachable. On-site, the driving member 9 and the limiting member 10 can be not installed on the fixed bracket. When the inclination angle needs to be adjusted, the adjustment operation can be realized by installing the driving member 9 and the limiting member 10. For multiple fixed brackets, a set of driving member 9 and limiting member 10 can be shared.

[0043] As Figure 1 shown, in this embodiment, the driving member 9 is arranged below the second connecting rod 4. Such an arrangement conforms more to the principle of human mechanics and is more convenient for applying force.
