Description

Adjustable photovoltaic support

technical field

The utility model relates to an adjustable photovoltaic bracket.

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 More and more researchers pay attention to green energy. 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.

Utility model content

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

In order to solve the above problems, the technical solution adopted by the utility model 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 the rear bracket, the front bracket is hinged with a swivel frame, 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; The swivel frame of the support frame is connected.

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 utility model 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 ways

The adjustable photovoltaic bracket described in 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 shape is 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, and the rear bracket 3 includes a base 31 and an arc-shaped U-shaped channel steel 32, and 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 supporting frames further includes at least one diagonal bracing rod 6 , one end of the diagonal bracing rod 6 is connected with the rotating frame 4 , and the other end of the diagonal bracing rod 6 is connected with the horizontal supporting rod 1 .
