[0059] The embodiment of the present invention provides a mobile photovoltaic power generation device, and its working principle is as follows:

[0060] The entire mobile photovoltaic power generation device is moved to a proper position by the universal wheel 54, and then the first self-locking screw 551 and the second self-locking screw 552 are rotated in the mounting cavity of the base 1. Under the action of the thread, the first movable frame 51 passes through the first positioning groove 531 and moves along the first limiting plate 571 to the upper side of the mounting cavity inside the base 1 under the limit of the first positioning plate 571, and the first guide sleeve 513 on the first limiting plate 511 slides upward along the first guide column 111, and the second guide sleeve 514 on the second limiting plate 512 slides upward along the second guide column 112; at the same time, under the action of the thread, the second movable frame 52 passes through the second positioning groove 532 and moves under the limit of the second positioning plate 572 The first movable frame 51 moves downward and moves along the second limiting plate 572 to the upper part of the installation cavity inside the base 1, and the third guide sleeve 517 on the third limiting plate 515 slides upward along the third guide column 113, and the fourth guide sleeve 518 on the fourth limiting plate 516 slides upward along the fourth guide column 114. At this time, the first movable frame 51 drives the two universal wheels 54 and the second movable frame 52 drives the two wheels to shrink from the corresponding through holes 58 to the inside of the base 1, and then the first self-locking screw 551 and the second self-locking screw 552 are fixed under the action of the first self-locking nut 561 and the second self-locking nut 562, so that the universal wheel 54 is fixed inside the installation cavity of the base 1 and contacts the ground through the lower surface of the base 1;

[0061] The driving motor 35 drives the rotating column 36 to rotate through the connecting shaft. At this time, the rotating column 36 drives the photovoltaic panel 2 to tilt through the mounting plate 37. The telescopic column 312 on the tilted side will shrink, and the telescopic column 312 on the raised side will stretch, thereby stabilizing the photovoltaic panel 2 and improving the safety and reliability. The light sensor 6 will sense the position of the sunlight and then transmit the signal to the adjusting motor 310. Then the adjusting motor 310 drives the rotating disk 31 to rotate through the driving rod 311. At this time, the rotating disk 31 rotates in the limiting groove 39 on the slot 38 through the limiting ring 32. When the rotating disk 31 rotates, the photovoltaic panel 2 follows the sunlight through the first support plate 33 and the second support plate 34. The first sprocket 43 drives the rotating rod 42 to rotate in the fixed column 41, and the rotating rod 42 drives the reciprocating screw 44 to rotate. Under the action of the thread, the threaded sleeve 45 drives the driving rack 46 to move up and down under the limit of the limit rod 47. As the driving rack 46 moves up and down, the half gear 410 drives the positioning rod 48 to rotate back and forth in the fixed column 41, thereby driving the focusing plate 49 to rotate synchronously. When the focusing plate 49 rotates, the concentrated sunlight moves on the photovoltaic panel 2. After absorbing the sunlight, the photovoltaic panel 2 converts it into electrical energy, thereby improving the utilization efficiency of solar energy.
