In this embodiment, the sun-by-day assembly 300 includes a lifting rod 310 and an adjusting structure 320, the lifting rod 310 is vertically disposed, and the adjusting structure 320 is fixed on top of the lifting rod 310 and connected to the photovoltaic power generation assembly 200;
the lifting rod 310 comprises an outer cylinder 311, a middle cylinder 312 and an inner rod 313, the outer cylinder 311 is arranged on the upper platen 101 in a penetrating manner and can slide along the upper platen 101 in a reciprocating manner, the middle cylinder 312 is arranged on the outer cylinder 311 in a penetrating manner and can slide along the outer cylinder 311 in a reciprocating manner, the inner rod 313 is arranged on the middle cylinder 312 in a penetrating manner and can slide along the middle cylinder 312 in a reciprocating manner, the upper end of the outer cylinder 311 can be abutted against the adjusting structure 320, the upper end of the inner rod 313 is connected with the adjusting structure 320, the lower end of the middle cylinder 312 is detachably connected with the lower platen 102, and the inner rod 313 can slide out of the middle cylinder 312 until the two are connected through the fixing structure;
correspondingly, the upper platen 101 is provided with a first through hole 104 which is matched with the outer cylinder 311, the bottom surface of the upper platen 101 is provided with a locking piece 700 which is used for clamping the outer cylinder 311 or the middle cylinder 312, and the top surface of the lower platen 102 is provided with an inserting hole which is matched with the middle cylinder 312 and a limiting plate 801 which is matched with the middle cylinder 312.
Based on the above design, the lifting rod 310 is used for realizing the reciprocating lifting of the sun-by-sun assembly 300, so as to adjust the height of the photovoltaic power generation assembly 200, and the adjusting structure 320 is used for adjusting the direction of photovoltaic power generation, and the two are mutually matched to realize the comprehensive adjustment of the photovoltaic power generation assembly 200.
Further, with respect to the lifting lever 310, the lifting lever 310 includes an outer cylinder 311, an intermediate cylinder 312, and an inner rod 313, and the intermediate cylinder 312 and the inner rod 313 can be housed in the outer cylinder 311, so that the lifting lever 310 reaches a minimum height, space occupation is reduced, the outer cylinder 311 can be lifted relative to the upper platen 101, and the intermediate cylinder 312 and the inner rod 313 can be lifted relative to the outer cylinder 311, so that the range of height adjustment is greatly expanded.
Specifically, when the upper end of the outer cylinder 311 is adjacent to the top surface of the upper platen 101, the lower end of the intermediate cylinder 312 is inserted into the insertion hole, and the lifting lever 310 reaches a minimum height. At this time, the intermediate cylinder 312 is clamped by the limiting plate 801 to fix the position of the intermediate cylinder 312. The outer cylinder 311 moves upwards to enable the photovoltaic power generation assembly 200 to rise, at the moment, the middle cylinder 312 keeps unchanged in position, and the inner rod 313 is connected with the adjusting structure 320, so that the outer cylinder 311 moves upwards; after the outer tub 311 is moved to a desired height, the outer tub 311 is fixed by the locking member 700.
When the outer cylinder 311 moves up to the position where the lower end thereof is adjacent to the upper platen 101, the outer cylinder 311 reaches the upward movement limit position, and the intermediate cylinder 312 is connected with the inner rod 313 by a fixed structure; at this time, if the photovoltaic power generation module 200 is further moved upward, the connection between the limiting plate 801 and the intermediate tube 312 is released, the intermediate tube 312 is moved upward, and the inner rod 313 is moved upward along with the intermediate tube 312, so that the photovoltaic power generation module 200 is moved upward. Meanwhile, the upper end of the outer cylinder 311 is separated from the adjusting structure 320. After the intermediate cylinder 312 is moved to a desired height, the intermediate cylinder 312 is passed through the outer cylinder 311 by the lock 700 and fixed.
In one possible implementation, the upper end of the middle cylinder 312 is provided with a clamping ring 301 located between the middle cylinder 312 and the inner rod 313, the lower end of the inner rod 313 is provided with a clamping hook 302 adapted to the clamping ring 301, the inner rod 313 can slide out of the middle cylinder 312 until the clamping hook 302 is clamped to the clamping ring 301, and accordingly, the clamping ring 301 and the clamping hook 302 form a fixed structure. Based on the above design, when the clamping hook 302 is clamped to the clamping ring 301, the middle cylinder 312 and the inner rod 313 are fixed to each other, so that the upward movement of the middle cylinder 312 is transmitted to the photovoltaic power generation module 200 through the inner rod 313, so that the photovoltaic power generation module 200 moves upward. Conversely, the inner rod 313 is depressed until the snap hooks 302 disengage from the snap rings 301, such that the inner rod 313 can again slide relative to the intermediate barrel 312.
Considering that the connection between the clamping hook 302 and the clamping ring 301 is realized by friction force, and the contact surface between the clamping hook 302 and the clamping ring 301 becomes smooth gradually after multiple uses, it is preferable to detachably connect the clamping hook 302 to the inner rod 313, so as to periodically replace the clamping hook 302, and ensure the stability of fixing the middle cylinder 312 and the inner rod 313.
Alternatively, the experimenter manually moves the outer cylinder 311 or the intermediate cylinder 312, based on which the structure of the lifting lever 310 is simple, also contributing to lower economic costs.
In this embodiment, the locking member 700 includes a case 710, a driving part 720, a clamping part 730, and a positioning part 740;
the box body 710 is provided with a second through hole 701 which is adapted to the outer cylinder 311, the box body 710 is internally provided with an installation space 702, and correspondingly, the driving part 720, the clamping part 730 and the positioning part 740 are all positioned in the installation space 702;
the driving part 720 comprises a driving motor 721, a driving ring 722 and a transmission block 723, wherein the output end of the driving motor 721 is connected with the driving ring 722 through a transmission gear, the driving ring 722 is rotatably arranged, the outer periphery of the driving ring 722 is configured as an adaptive transmission tooth surface, at least two transmission blocks 723 are arranged on the inner periphery of the driving ring 722, and the side surface of the transmission block 723 facing the second through hole 701 is configured as a clamping inclined surface;

The driving part 720 provides power to reciprocate the clamping part 730, thereby achieving clamping and unclamping. The positioning portion 740 is used for fixing the position of the clamping portion 730, so that the clamping portion 730 is kept at a certain position, and false touch is avoided.
Specifically: when it is desired to clamp the lifting rod 310, the driving motor 721 is activated and rotates the driving ring 722, and the rotation of the driving ring 722 is transmitted to the clamping plate 731 through the transmission block 723. Meanwhile, since the driving block 723 abuts the clamping plate 731 through the clamping slope, the clamping plate 731 is moved toward the second through hole 701 by the slope change of the clamping slope until the clamping surface of the clamping plate 731 contacts and abuts the lifting rod 310, thereby achieving clamping. The positioning part 740 is restarted, and the telescopic rod 741 extends outwards and is inserted into the positioning hole 703, so that the position of the driving ring 722 is fixed.
Conversely, when the lifting lever 310 needs to be released, the positioning portion 740 is activated, and the telescopic lever 741 is retracted and released from the positioning hole 703. The driving motor 721 is restarted to rotate and reset the driving ring 722, the driving block 723 is also gradually separated from the clamping plate 731, and the clamping plate 731 is reset under the action of the reset spring. After resetting, the clamping plate 731 is retracted in the case 710 and is disengaged from the lifter 310, at which time the experimenter can move the lifter 310 again.

Based on the above design, the upper case 711 and the lower case 712 are fastened to form the case 710, otherwise, the upper case 711 and the lower case 712 may be separated to inspect and maintain the driving portion 720, the clamping portion 730 and the positioning portion 740, so as to improve the service life of the locking member 700.
