The actuating lever 51 is connected to the output of the motor 40 so that the actuating lever 51 can be driven by the motor 40 to rotate about the axis of the output of the motor 40. That is, upon actuation of the motor 40, the actuation lever 51 may rotate about the axis of the output of the motor 40.

Wherein the starting rod 51 is connected with the output end of the motor 40 mainly through a driving shaft 55. The driving shaft 55 is fixedly connected to the output end of the motor 40 and can rotate relative to the bracket 10. The start rod 51 is sleeved on the driving shaft 55 and rotates synchronously with the driving shaft 55, so that the start rod 51 can rotate around the axis of the output end of the motor 40 when the output end of the motor 40 rotates.

One end of the connecting rod 52 is connected to the end of the actuating rod 51 facing away from the motor 40, and the other end is connected to the slider 53. Thus, when the motor 40 is started, the connecting rod 52 can be moved by the starting rod 51. One end of the connecting rod 52 is rotatably connected to the actuating rod 51, and the other end is rotatably connected to the slider 53.

The slider 53 is provided in the chute 11 and is reciprocatingly movable in the chute 11 in the height direction of the bracket 10. Specifically, when the connecting rod 52 is moved by the actuating rod 51, the connecting rod 52 may drive the slider 53 to reciprocate in the height direction of the bracket 10 within the chute 11.

The description will be given taking an example in which the plate 20 moves toward the bracket 10, that is, the angle between the plate 20 and the bracket 10 is reduced. The output end of the motor 40 rotates in a clockwise direction, the start rod 51 and the driving shaft 55 synchronously rotate in a clockwise direction, and the end of the start rod 51 away from the driving shaft 55 pulls the connecting rod 52 to move downwards, so that the sliding block 53 is pulled to move downwards through the connecting rod 52. At the same time, the traction rod 54 connected to the slider 53 is pulled by the slider 53 to move downward to pull the flat plate 20 to rotate downward, thereby reducing the angle between the flat plate 20 and the stand 10.

The description will be given taking as an example that the plate 20 moves away from the bracket 10, i.e. the angle between the plate 20 and the bracket 10 is increased. The output end of the motor 40 rotates in a counterclockwise direction, the start rod 51 and the driving shaft 55 rotate in a counterclockwise direction simultaneously, and the end of the start rod 51 away from the driving shaft 55 pushes the connecting rod 52 to move upwards, so that the slide block 53 is pushed to move upwards through the connecting rod 52. Meanwhile, the traction rod 54 connected to the slider 53 is pushed by the slider 53 to move upward to push the flat plate 20 to rotate upward, thereby increasing the angle between the flat plate 20 and the bracket 10.

In a specific implementation, the number of the adjusting assemblies 50 is two, and the two adjusting assemblies 50 are respectively arranged at two opposite sides of the bracket 10, so that stability of controlling the flat plate 20 is realized. The number of slide grooves 11 opposite to the adjusting assembly 50 may be two or one.

The slide rail may be disposed at the left and right inner walls or at the bottom of the chute 11, and two slide blocks 53 are disposed correspondingly. The specific arrangement form of the slide groove 11 and the slide rail is not limited.

According to the embodiment of the utility model, the rotation angle of the flat plate 20 is regulated by arranging the regulating component 50, so that the angle of the solar panel 30 arranged in the flat plate 20 can be changed along with the movement direction of the sun, and the solar panel 30 can receive more sunlight, thereby improving the light energy conversion rate. In addition, the adjusting assembly 50 in the embodiment of the utility model comprises the actuating rod 51, the connecting rod 52, the sliding block 53 and the traction rod 54, and the rotation of the flat plate 20 can be controlled by arranging the form of matching three connecting rods with one sliding block 53, so that the stability in the rotation process of the flat plate 20 can be ensured, and the actuating rod 51, the connecting rod 52, the sliding block 53 and the traction rod 54 do not occupy excessive installation space, thereby being beneficial to saving the installation space.

With continued reference to fig. 1, the edge of the flat plate 20 is provided with an elongated slot 22, the extending direction of the elongated slot 22 is the same as that of the placement slot 21, and the elongated slot 22 is disposed adjacent to and communicates with the placement slot 21. The photovoltaic power generation device further includes a clamping block 60 and a securing assembly 70. The clamp block 60 is movably disposed within the elongated slot 22. Since the long groove 22 is adjacent to and communicates with the placement groove 21, and the solar panel 30 is disposed in the placement groove 21, the clip 60 can move in the direction approaching or separating from the solar panel 30 in the long groove 22. The fixing assembly 70 is connected to the flat plate 20 and the clamping block 60, respectively, to adjust the distance between the clamping block 60 and the solar panel 30.

In some embodiments, the length of the slot 22 is less than the length of the placement slot 21, thereby preventing the solar panel 30 from backing out of the slot 22. Wherein the width of the placement groove 21 is larger than the width of the solar panel 30, and the width of the long groove 22 is larger than the width of the clamping block 60. The specific widths of the placement groove 21, the elongated groove 22, and the clamping block 60 can be adaptively adjusted according to the actual width of the solar panel 30, which is not described herein.

In some embodiments, the elongated slot 22, the clamp block 60, and the securing assembly 70 are disposed in a one-to-one correspondence. Wherein the number of elongated slots 22 is one or two.

Specifically, the number of elongated slots 22 is one, the number of clamping blocks 60 is one, and the number of fixing assemblies 70 is one. The slot 22, the clamp block 60 and the securing assembly 70 are disposed on either side of the plate 20.

With continued reference to FIG. 1, the number of elongated slots 22 is two, the number of clamping blocks 60 is two, and the number of securing assemblies 70 is two. At this time, the long groove 22, the clamping block 60 and the fixing member 70 are disposed on opposite sides of the flat plate 20.

In some embodiments, the securing assembly 70 includes a T-bar 71 and a connector 72. The middle vertical rod of the T-shaped rod 71 is connected with the clamping block 60, and the middle vertical rod and the clamping block can be fixedly connected. The middle vertical rod of the T-shaped rod 71 can push the clamping block 60 to move along the long groove 22 towards the direction of the placement groove 21, so that the clamping block 60 moves to a preset position and abuts against the solar panel 30, and the solar panel 30 is clamped.

Wherein, the both ends of T type pole 71 are provided with first connecting hole 711, are provided with the second connecting hole 23 on the flat board 20, and the axial projection coincidence of first connecting hole 711 and second connecting hole 23. The connection member 72 sequentially passes through the first connection hole 711 and the second connection hole 23 to fix the T-bar 71 to the flat plate 20 so that the clamping block 60 moves to a predetermined position to clamp the solar panel 30.

In some embodiments, the first and second connection holes 711 and 23 are threaded holes, and the connection member 72 is a threaded member. Wherein the first and second connection holes 711 and 23 may have internal threads, and the connection member 72 may have external threads. When the connection member 72 is penetrated in the first connection hole 711 and the second connection hole 23, the connection member 72 may be screw-coupled with the first connection hole 711 and the second connection hole 23, thereby allowing the T-bar 71 to be fixed to the flat plate 20 by screwing the connection member 72. By fixing the T-bar 71 to the flat plate 20, the clamping block 60 is moved to a preset position so that the clamping block 60 can clamp the solar panel 30. When the solar panel 30 needs to be replaced or overhauled, the solar panel 30 can be disassembled only by reversely rotating the connecting piece 72, so that the solar panel 30 is convenient to disassemble and assemble.

The number of fixing members 70 may be one or two, as already described above. But in each set of the fixing members 70, the number of the first connection holes 711 and the connection members 72 is two. Each set of fixing members 70 corresponds to two second connection holes 23.

With continued reference to fig. 1, first connection holes 711 are provided at both end portions of the cross bar of the T-bar 71, and second connection holes 23 are provided at positions corresponding to the flat plates 20 such that axial projections of the first connection holes 711 and the second connection holes 23 coincide.

With continued reference to fig. 1, the clamping process of the securing assembly 70 will be described using the connecting member 72 as a threaded member.

Pushing the T-bar 71 causes the T-bar 71 to drive the clamping block 60 to move from the elongated slot 22 to the placement slot 21, thereby reducing the distance between the clamping block 60 and the solar panel 30. The connecting piece 72 is sequentially inserted into the first connecting hole 711 and the second connecting hole 23, and the connecting piece 72 is screwed. As the connector 72 is tightened, the distance between the clamping block 60 and the solar panel 30 is reduced until the clamping block 60 moves to a predetermined position, at which time the connector 72 has been tightened to its maximum extent, the T-bar 71 is secured to the flat plate 20, and the solar panel 30 is clamped.

It should be noted that the mounting sequence of the two sets of fixing assemblies 70 is not limited, and the mounting sequence of the fixing assemblies 70 and the solar panel 30 is not limited.
