Description

Adjustable photovoltaic support

technical field

The invention relates to an adjustable photovoltaic support.

Background technique

Due to the shortage, non-renewability and pollution of natural resources such as oil, coal and natural gas, the development of renewable and pollution-free energy has become an important direction of energy research. Solar energy is an inexhaustible and inexhaustible Green energy has attracted more and more attention from researchers. The application of solar energy usually converts the absorbed sunlight into electrical energy through solar panels. Solar panels are usually installed on the roof or on the ground through brackets. Currently used brackets are usually of a fixed structure, and after the solar panel is fixed on the bracket, it can only be placed at a fixed inclination angle. But the amount of power generated by a solar panel has a lot to do with the angle at which sunlight hits the solar panel.

The movement law of the sun's light angle: On the same day, the sun rises from the east and sets from the west, and rises to the highest point at 12 noon, but the sun does not rise from the due east and set due to the west every day. The direction of sunrise and sunset changes greatly. As a result, the above-mentioned photovoltaic support cannot achieve maximum power generation for different seasons in different seasons.

Contents of the invention

The technical problem to be solved by the present invention is to provide an adjustable photovoltaic support with adjustable inclination angle.

In order to solve the above problems, the technical solution adopted by the present invention is: the adjustable photovoltaic support includes at least two sets of support frames and horizontal support bars arranged above the support frames, and each set of support frames includes a front support fixed to the foundation and a The rear bracket is hinged with a swivel frame on the front bracket, the front end of the swivel frame is hinged with the front bracket, the rear end of the swivel frame is movably arranged in the rear bracket, and can be locked with the rear bracket; Connected to the swivel frame of the frame.

The swivel frame has a fan-shaped structure, and its rear end is shaped as a circular arc centered at the hinge point between the swivel frame and the front frame. The shape of the rear frame is an arc matching the shape of the rear end of the rotary frame.

The rear support includes a base and an arc-shaped U-shaped channel steel, and the rear end of the rotating frame is arranged in the U-shaped channel of the U-shaped channel steel.

The corresponding positions of the rotating frame and the rear bracket are respectively provided with several locking holes, and the locking of the rotating frame and the rear bracket is realized by setting the pin shafts in the locking holes.

Each set of supporting frames further includes at least one diagonal bracing rod, one end of the diagonal bracing rod is connected with the rotating frame, and the other end of the diagonal bracing rod is connected with the horizontal supporting rod.

The beneficial effects of the present invention are: the above-mentioned adjustable photovoltaic support has a simple structure and is easy to use, and the inclination angle can be adjusted according to different geographical locations and seasons, and the inclination angle range is generally designed between 20 degrees and 45 degrees. It can keep the solar panel at the best sunlight receiving angle, so as to achieve the maximum power generation in a year, and it will not increase much cost due to the single-angle fixed bracket. And with a solid construction and no moving parts, it requires little to no ongoing maintenance.

detailed description

The adjustable photovoltaic support of the present invention will be further described in detail through specific embodiments below.

As shown in Figure 1, the adjustable photovoltaic support includes at least two sets of support frames and a horizontal support bar 1 arranged above the support frames. In this embodiment, four sets of support frames are included, and each set of support frames includes a front fixed to the foundation. Support 2 and rear support 3, front support 2 is hinged with swivel frame 4, the front end of swivel frame 4 is hinged with front support 2, and the rear end of swivel frame 4 is movably arranged in rear support 3, and can be connected with rear support 3 Locking; the horizontal support bar 1 is connected with the rotating frame 4 of each group of supporting frames. The swivel frame 4 is a fan-shaped structure composed of several materials, and its rear end is shaped as a circular arc with the hinge point between the swivel frame 4 and the front bracket 2 as the center of the circle. As shown in Figure 2, the rear bracket 3 The shape is an arc shape matched with the shape of the rear end of the swivel frame 4. The rear bracket 3 includes a base 31 and an arc-shaped U-shaped channel steel 32. The rear end of the swivel frame 4 is arranged on the U-shaped groove. In the U-shaped groove of the steel 32, several locking holes 5 are respectively arranged at the corresponding positions of the swivel frame 4 and the rear bracket 3, and the locking of the swivel frame 4 and the rear bracket 3 is realized by being arranged in the locking holes 5 by pin shafts. Each set of support frames further includes at least one diagonal brace 6 , one end of the diagonal brace 6 is connected to the swivel frame 4 , and the other end of the diagonal brace 6 is connected to the horizontal support rod 1 . The cross-section of the arc-shaped bracket of the above-mentioned rear bracket 3 can also be in other shapes, not necessarily U-shaped, for example, it can be in the shape of a flat plate. As long as it can form a sliding and fixed connection with the rotating frame 4 .

When the above-mentioned adjustable photovoltaic bracket is in use, fix the solar panel and the horizontal support rod 1, and rotate the rotating frame 4 to a suitable angle according to the direction change of sunrise and sunset in different seasons, and pass the pin Insert it into the locking hole 5, so that the swing frame and the rear bracket 3 are relatively fixed, so that the solar panel maintains the best sunlight receiving angle, so as to achieve the maximum power generation without increasing the cost.

The above-mentioned embodiment only illustrates the principle of the present invention and its effect, and the embodiment of partial use, but is not intended to limit the present invention; It should be pointed out that for those of ordinary skill in the art, without departing from the Under the premise of creating ideas, some modifications and improvements can also be made, which all belong to the protection scope of the present invention.
