[0002] The application of solar energy is usually through solar panels to convert absorbed sunlight into electrical energy. The solar panels are usually arranged on the roof or ground through a support. The support currently used is usually a fixed structure, and the solar panels can only be placed at a fixed angle after being fixed on the support. However, the power generation of the solar panels has a great relationship with the angle of sunlight on the solar panels.

The support plate 6 adjusts its own slope through the deflection mechanism and is vertically flipped through the flip mechanism; the support plate 6 located on the shady side can be controlled to flip upward so that the photovoltaic panel on it can leave the shadow area and be adjusted to face the effective light direction;

The cleaning and protection component includes a cleaning frame 7 and a folding protective plate 8. The folding protective plate 8 is installed on the outside of the cleaning frame 7. The power component is connected to the cleaning frame 7 to drive the cleaning frame 7 to move up and down. When the cleaning frame 7 is lifted upward under power drive, the folding protective plate 8 is subjected to traction and gradually extends from a compressed folded state to an unfolded state. When the cleaning frame 7 is reset downward, the folding protective plate 8 shrinks back to the folded state.

[0025] In this embodiment, the flipping mechanism includes a telescopic cylinder 9 and an adjusting seat 10. The adjusting seat 10 is rotatably assembled on the support 4. The fixed end of the telescopic cylinder 9 is hingedly arranged on the pillar 3. The end of the rotating shaft of the adjusting seat 10 is provided with an eccentric block 11. The piston rod of the telescopic cylinder 9 is hingedly connected to the deflection block. The left and right sides of the rear end surface of the support plate 6 are connected with vertical rods 12, and the tops of the vertical rods 12 on both sides are connected with a cross frame 13.

The output shaft of the motor is sleeved with a second bevel gear 19 that is transmission-connected to the first bevel gear 17.

[0026] The working principle of the light adjustment in this embodiment is as follows:

[0027] 1. Shadow avoidance mechanism: When a photovoltaic panel is on the shaded side, the flip mechanism is activated: the telescopic cylinder 9 pushes the piston rod, acting on the eccentric block 11 at the end of the adjustment seat 10, driving the adjustment seat 10 to rotate around the support 4, and the support plate 6 is then flipped vertically (e.g. 0°~150°), so that the photovoltaic panel can leave the shadow area and turn to the effective light direction; Figure 3 As shown, when the sun is in the front side, the photovoltaic panels located on the rear side can be flipped upward to face the sun; and when the sun is directly overhead at noon, all the support plates 6 can be flipped synchronously to a horizontal state. In the horizontal state, the light-receiving area of ​​the photovoltaic panels is maximized, thereby improving the utilization rate of direct sunlight at noon.

[0028] 2. Precise adjustment of the inclination angle: The first motor 18 at the top of the adjustment seat 10 drives the second bevel gear 19, which meshes with the first bevel gear 17 on the cross frame 13 of the support plate 6, thereby driving the rotating rod 16 to rotate through the first motor 18, so that the support plate 6 deflects around the connecting piece 15 to achieve slope adjustment, and cooperate with the flip adjustment of the flip mechanism to adapt to the change of the solar altitude angle; Figure 3 As shown, the photovoltaic panels located on the side can be synchronously adjusted through the flipping mechanism and the deflection mechanism to turn to the direction of light.

[0031] In the embodiment, the side end of the top plate 22 is provided with a plurality of bases 29 corresponding to the connecting seats 23, each of the bases 29 is hingedly provided with a protective rod 30, and a torsional spring is connected between the rotating shaft of the protective rod 30 and the base 29, and the protective rod 30 is in a vertical state at the initial stage of the torsional spring; the end of the protective rod 30 away from the top plate 22 is provided with an inclined block 31, and the top end of the connecting seat 23 is provided with a corresponding push block 32, when the connecting seat 23 rises, the push block 32 abuts against the inclined block 31, and drives the protective rod 30 to rotate to a horizontal state.

[0032] The cleaning and protection working principle of the embodiment is as follows:

[0033] 1. Cleaning mechanism: when the photovoltaic panel is used for a period of time, such as three months, the cleaning frame 7 is driven to rotate by the motor in the base 1 to drive the lead screw 20 to rotate, and the connecting seat 23 is vertically lifted to drive the cleaning frame 7 to vertically lift along the support column 21; the nylon cleaning bristles on the inner wall of the frame body are flexible and scraped against the surface of the photovoltaic panel during the lifting process, the floating dust is swept away when going up, and the adhered dirt is removed when going down, so that the impurities on the photovoltaic panel are removed and cleaned, and the cleaning bristles are cleaned by manual operation regularly, such as once a year.

[0034] 2. Protection mechanism: the built-in system determines to start the protection mode by integrating meteorological sensors (such as anemometer, rain and snow sensor) or receiving external weather warning, sends a signal to the second motor to drive the lead screw 20 to rotate, drives the cleaning frame 7 to vertically rise, and the nested protective cover 26 (made of lightweight aluminum alloy / composite material) is released layer by layer under the traction of the cleaning frame 7, and the outer protective cover 26 is driven to rise by the moving groove 27 and the limiting block 28 abutting, and after unfolding, a continuous inclined plane barrier is formed, which effectively disperses the impact force of hail and guides the accumulated snow / rain to slide off; and the unfolded barrier can resist strong wind force, avoid strong wind blowing photovoltaic panels, and also resist hard objects (such as gravel, branches, etc.) hitting photovoltaic panels;

[0035] When the cleaning frame 7 vertically rises to the top point, the protective rods 30 at the side end of the top plate 22 are extruded by the push block 32 of the connecting seat 23, and are turned inward to overcome the torsional spring force, thereby synchronously unfolding the protective rods 30 around to form a falling object protection net to protect the photovoltaic panels in the top mounting groove 25, avoid heavy objects from falling from above to damage the top photovoltaic panels, and after the connecting seat 23 is lowered and reset, the protective rods 30 are turned to the vertical state again under the reset force of the torsional spring to avoid affecting the light area of the top photovoltaic panels, and the protective rods 30 can be made of light-transmitting material to avoid blocking the light.
