The photovoltaic panel comprises three states, namely an overhaul state, a working state and a protection state.
In the maintenance state, the motor 6 is used for driving the mounting frames 3 to drive the photovoltaic panels 4 to rotate by 90 degrees by taking the first rotating rod 31 as a rotating shaft and fixing the photovoltaic panels, so that the plane of each photovoltaic panel 4 is perpendicular to the axis of the second rotating rod 33, and in the state, a space for a worker to walk is formed between two adjacent mounting frames 3, thereby being convenient for the worker to carry out maintenance and repair operation on the photovoltaic panels 4 at any position.
The working state is that the plane of each photovoltaic panel 4 is kept parallel to the axis of the second rotating rod 33, the mounting frame 3 is driven by the motor 6 to drive the photovoltaic panels 4 to rotate by taking the second rotating rod 33 as a rotating shaft according to the solar altitude angle, each photovoltaic panel 4 is adjusted to be in a state of being completely irradiated by sunlight, and in the state, the problem that two adjacent photovoltaic panels 4 are shielded by light is avoided, and the photovoltaic panels 4 can be cooled to different degrees according to the difference of horizontal angles between the photovoltaic panels 4 and the base 1, so that the photoelectric conversion rate of each photovoltaic panel 4 to light is ensured;
The protection state is that on the basis of the working state, the motor 6 is utilized to drive the mounting frame 3 to rotate by taking the second rotating rod 33 as a rotating shaft until the horizontal included angle between the mounting frame 3 and the base 1 reaches the minimum value, and referring to fig. 8, in the state, the photovoltaic panel 4 can be effectively prevented from being damaged in strong wind weather, so that the photoelectric conversion rate of the photovoltaic panel 4 in use can be ensured.
Specific:
When any photovoltaic panel 4 needs to be overhauled and maintained, the motor 6 is started to rotate positively, the sleeved driving cam 72 between the driving rod 71 and the cam 72 can be utilized to rotate in the process of the positive rotation of the motor 6, so that the first rotating rod 31 is driven to rotate by utilizing the transmission effect between the cam 72 and the driving rack 73, the driving wheel 74, the second rotating rod 33, the second bevel gear 76, the first bevel gear 75 and the first rotating rod 31, when the first rotating rod 31 rotates, the corresponding photovoltaic panel 4 can be driven to rotate by the mounting frame 3 until the plane of the photovoltaic panel 4 is in a vertical state with the axis of the second rotating rod 33, in this state, the gap between the two adjacent mounting frames 3 is the largest, the overhauling and maintenance operation of the photovoltaic panel 4 at any position can be conveniently carried out by a worker without drilling the bottom of the corresponding photovoltaic panel 4, and after the overhauling, the motor 6 continues to rotate positively until the plane of the photovoltaic panel 4 is parallel with the axis of the second rotating rod 33;
When the solar elevation angle is increased in summer, the driving motor 6 is reversed, the reciprocating screw rod 81 is driven to rotate through the sleeving connection between the driving rod 71 and the reciprocating screw rod 81 in the reversing process of the motor 6, so that the left end of the mounting frame 3 is driven to be lifted upwards by utilizing the transmission effect between the reciprocating screw rod 81 and the sliding block 82, the connecting rod II 83, the supporting piece 84, the supporting plate 85, the connecting rod III 86 and the connecting rod III 34, the horizontal mounting angle of the photovoltaic panel 4 is increased, the photoelectric conversion rate of the photovoltaic panel 4 is ensured by properly reducing the illumination angle under the high-temperature condition, and in the process, the two ends of the supporting piece 84 respectively drive the corresponding baffle plates 10 to move leftwards, so that the two baffle plates 10 are respectively staggered with the corresponding air inlets 9111 on the diversion box 9, the caliber of the air inlets 9111 is increased, and air flow can be blown upwards to the back of the photovoltaic panel 4 from the air inlet III 9131 after entering the air guide groove 9121 through the air inlets 9111, so that the photovoltaic panel 4 is effectively cooled, and the photoelectric conversion rate of the photovoltaic panel 4 in the limited range of a roof is prevented;
on the contrary, when the solar altitude angle is reduced in winter, the left end height of the mounting frame 3 is adjusted downwards, the exposed caliber of the air inlet 9111 is reduced, and the convection heat dissipation of the back surface of the photovoltaic panel 4 is reduced, so that the photovoltaic panel 4 can ensure the photoelectric conversion rate of light rays in a limited range of a roof under a low-temperature environment.
