DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A photovoltaic assembly adjustment mechanism includes a support assembly and an adjustment assembly, wherein the adjustment assembly is mounted on the support assembly; the support assembly is used to install and support the photovoltaic panel assembly, and the adjustment assembly is used to adjust the installation inclination angle of the support assembly, thereby adjusting the inclination angle of the solar cell panel.

[0022] Reference Figure 1 The supporting assembly includes a fixing plate 11, a U-shaped vertical shell 12, a lifting column 14, a side frame 15 and a cross frame 17. The fixing plate 11 is circular and is installed on the prefabricated piles by bolts. The fitting area is larger and more stable. The prefabricated piles are counterweights made of cement, which are used to improve the overall quality and prevent the solar panel assembly from being blown down by the wind after installation. The U-shaped vertical shell 12 is fixedly connected to the fixing plate 11 by bolts. The lifting column 14 is slidably connected to the inner side wall of the U-shaped vertical shell 12. The side frame 15 is welded to the lifting column 14, and the cross frame 17 is rotatably connected to the side frame 15. A reinforcing rod 16 is welded on one side of the lifting column 14. The top of the reinforcing rod 16 is fixedly connected to the side frame 15. The reinforcing rod 16 is used to strengthen the stability of the side frame 15. The lifting column 14 of the utility model can be lifted up and down by adjusting the assembly. The height difference between the upper and lower ends of the photovoltaic panel assembly is increased by lifting the lifting column 14, thereby changing the inclination angle of the photovoltaic panel.

[0023] Reference Figure 2 and Figure 3 The adjusting assembly includes a screw rod 21 and a knob 22. A bottom groove 13 is provided at the bottom of the U-shaped housing 12. The knob 22 is arranged in the bottom groove 13. One end of the screw rod 21 passes through the bottom of the U-shaped housing 12 and is rotatably connected thereto. The upper end of the screw rod 21 passes through the lifting column 14 and is threadedly connected to the lifting column 14. The bottom of the lifting column 14 is thickened to increase the contact area with the screw rod 21 and improve stability. The interior is a hollow structure to reduce the overall manufacturing cost. When the screw rod 21 rotates, it will drive the lifting column 14 to move up and down. The top end of the screw rod 21 is rotatably connected to a square slide, and the square slide is slidably connected to the inner side wall of the lifting column 14. When the lifting column 14 rises to a certain height, its inner bottom contacts the square slide to limit its continued rise. The knob 22 is welded to the bottom end of the screw rod 21, and the rotation of the screw rod 21 is controlled by the knob 22.

[0024] Specifically, the support assembly also includes a bracket 19 and a rotating seat 111. The rotating seat 111 is rotatably connected to the top of the bracket 19. The top of the rotating seat 111 is fixedly connected to the cross frame 17 by bolts. The bottom of both sides of the bracket 19 are symmetrically installed with L-shaped steel plates 110 by bolts. The L-shaped steel plates 110 are installed on the prefabricated concrete piles by bolts. The position of the bracket 19 can move with the bottom prefabricated concrete piles, which is convenient for adjusting the operation of the assembly.

[0025] Specifically, a longitudinal frame 18 is installed on the top of the horizontal frame 17 by bolts. A track groove is opened on the longitudinal frame 18. Photovoltaic components are clamped on the longitudinal frame 18. Photovoltaic solar panels are installed on the longitudinal frame 18. When the inclination angle of the longitudinal frame 18 changes, the inclination angle of the photovoltaic solar panels changes synchronously.

[0026] Specifically, a pin ring 23 is provided on the knob 22, and two symmetrically arranged pins 24 are fixedly connected to the bottom of the pin ring 23. Four holes distributed in an annular pattern are provided on the knob 22, and the pins 24 pass through the holes. A pin disk 25 is welded on the fixing plate 11, and four pin holes 26 distributed in an annular pattern are provided on the pin disk 25, and the bottom end of the pin 24 is inserted into the pin hole 26. When rotating the knob 22, the pin ring 23 needs to be pulled up to pull the pin 24 out of the pin disk 25. After the knob 22 is rotated, the pin ring 23 is released, and the pin 24 on it is inserted into the pin hole 26 of the pin disk 25 under the action of gravity, thereby fixing the knob 22 and the screw rod 21, and preventing the height of the lifting column 14 from being offset.

[0027] The U-shaped housing 12 of the utility model is provided with scale lines, and the lifting columns 14 are provided with reference scales, so that the staff can grasp the specific lifting height of the lifting columns 14 conveniently.

[0028] Working principle: first determine the inclination angle of the photovoltaic module according to the specific environment, pull up the pin ring 23, pull the pin rod 24 out of the pin disk 25, rotate the knob 22, drive the screw rod 21 to rotate, and drive the lifting column 14 to move up and down, so as to adjust the height position of the side frame 15, that is, adjust the height of the left end of the photovoltaic module. When the inclination angle of the photovoltaic module reaches the preset value, loosen the pin ring 23, and under the action of gravity, the pin rod 24 thereon is inserted into the pin hole 26 of the pin disk 25 to complete self-locking, thereby fixing the knob 22 and the screw rod 21 to prevent the height of the lifting column 14 from shifting. The support assembly is installed on the prefabricated cement pile at the bottom by screws, and then the photovoltaic module is installed on the vertical frame 18. The operation is simple, convenient and fast, and it will not take up more ground area.
