[0033] Furthermore, the planetary reduction mechanism 204 includes an inner gear ring 204a disposed below the first L-shaped plate 103, a first gear 204b disposed at the end of the gear rod 202d, a gear frame 204c disposed at the bottom of the rotating rod 301, and a plurality of second gears 204d disposed on the surface of the gear frame 204c.

[0034] Furthermore, the rotating rod 301 includes a second limit block 301 a disposed on the rod body thereof, and a second sleeve 301 b disposed on the top of the rotating rod 301 .

[0035] Furthermore, the swing column 302 includes a swing rod 302a disposed on one side thereof, a ball head 302b disposed at the end of the swing rod 302a, a second L-shaped plate 302c disposed on the other side of the swing column 302, and a photovoltaic frame 302d disposed on one side of the second L-shaped plate 302c.

[0036] Furthermore, the lifting ring 303 includes an annular cavity 303a disposed inside the lifting ring 303, an L-shaped rod 303b disposed on one side of the outer wall of the lifting ring 303, and a trigger rod 303c disposed on one side of the L-shaped rod 303b.

[0037] Furthermore, it also includes a photovoltaic panel M arranged on one side of the swing column 302.

[0038] It should be noted that the container 101 is box-shaped, and there is space inside for placing the first motor 201, the battery, the inverter and other devices, and the bottom panel of the container 101 is fixed with bolts. Two symmetrically distributed spherical support frames 102 are fixed on the upper surface of the container 101, and the support surface of the spherical support frame 102 is spherical, which is used to support the hollow ball 203, and the two are in surface contact.

[0039] Preferably, the first motor 201 is fixed to the upper surface of the containing box 101 by bolts and is located at the center between the two spherical support frames 102 , with the rotating shaft facing upward and the body penetrating into the inside of the containing box 101 .

[0040] Preferably, the first L-shaped plate 103 is fixed to the edge of the upper surface of the housing 101 and is located on the symmetry axis of the two spherical support frames 102. The first L-shaped plate 103 is in an inverted L shape and is composed of two horizontal and vertical plates. The horizontal plate is located directly above the rotating shaft of the first motor 201, and a through strip groove 104 is provided at the center of the vertical plate. In addition, a positioning rod 105 is fixed directly above the upper end of the vertical plate.

[0041] Preferably, the strip groove 104 can accommodate the trigger rod 303c, the groove wall is tangent to the rod body of the trigger rod 303c, and the positioning rod 105 completely passes through the center of the crossbar of the L-shaped rod 303b, and the two are movably connected.

[0042] Preferably, the shaft end of the first motor 201 is fixedly connected to the transmission rod 202. Specifically, the connecting rod 202b is sleeved on the shaft end of the first motor 201, and the two are fixed by bolts passing through the side wall of the connecting rod 202b.

[0043] Preferably, a gear rod 202d and a connecting rod 202b are fixed to the upper and lower sides of the first sleeve 202a, respectively, and the axes of the two rods are collinear. A first gear 204b is sleeved on the upper end of the gear rod 202d, and the two are fixedly connected by a key, so that the first motor 201 can drive the first gear 204b to rotate by dragging the transmission rod 202.

[0044] The first sleeve 202a is sleeved on the center of the rod body of the support rod 203a, and a first limit block 203c and a worm gear 203d are fixed on the support rod 203a on both sides of the first sleeve 202a. The support rod 203a is distributed laterally and movably connected with the first sleeve 202a, and the first limit block 203c and the worm gear 203d limit the first sleeve 202a to prevent the hollow ball 203 from moving laterally.

[0045] A U-shaped frame 202c is fixed to one side of the connecting rod 202b, and the U-shaped frame 202c is located on the side with the worm wheel 203d and completely wraps the outer circumference of the worm wheel 203d. Two holes are respectively opened at the upper end of the U-shaped frame 202c, that is, on the two vertical rods of the U-shaped frame 202c, and the two ends of the worm 206 are directly sleeved therein. Therefore, the worm 206 can directly mesh with the worm wheel 203d below.

[0046] A second motor 205 is also fixed on the side wall of the U-shaped frame 202c, and the shaft end of the second motor 205 is fixedly connected to the end of the worm 206, so that the second motor 205 can directly drive the worm 206 to rotate, thereby driving the support rod 203a to rotate. Therefore, the hollow ball 203 can rotate with the support rod 203a as the axis.

[0047] Preferably, both ends of the support rod 203a are fixedly connected to the inner wall of the hollow ball 203. Figure 5 The O-shaped inclined groove 203b is opened around the outer wall of the hollow ball 203 and penetrates the spherical surface. In addition, the O-shaped inclined groove 203b is a symmetrical structure, and the direction of the groove needs to pass through the two ends of the support rod 203a at the same time. Figure 5 In the figure, the support rod 203a is located at the center of the O-shaped inclined groove 203b.

[0048] When the centers of the two through openings of the hollow ball 203 are on the axis of the gear rod 202d, the hollow ball 203 is in the initial position, the O-shaped inclined groove 203b has an inclination and a height difference, and the trigger rod 303c can extend into it. When the transmission rod 202 rotates, the hollow ball 203 can rotate with the gear rod 202d as the axis, thereby driving the trigger rod 303c to move up and down repeatedly. It should be noted that the slot width of the O-shaped inclined groove 203b is slightly larger than the rod diameter of the trigger rod 303c.

[0049] Preferably, an inner gear ring 204a is fixed on the lower surface of the horizontal plate of the first L-shaped plate 103, and the center of the inner gear ring 204a is collinear with the axis of the gear rod 202d. The rotating rod 301 completely passes through the horizontal plate, and the rotating rod 301 is limited by the second limit block 301a fixed on the rod body and the gear rack 204c at the bottom of the rod, but the rotating rod 301 can rotate around its own axis, and the axis of the rotating rod 301 is also collinear with the axis of the gear rod 202d.

[0050] Preferably, the gear rack 204c is triangular in shape, and limiting rods for penetrating the center of the second gear 204d are fixed at the three corner positions. The second gear 204d can rotate around the limiting rods as the axis. In addition, there are three second gears 204d, all of which are engaged with the inner gear ring 204a.

[0051] The first gear 204b is respectively meshed with each second gear 204d. Since the transmission rod 202 is fixedly connected to the first gear 204b, when the transmission rod 202 rotates, the gear frame 204c can be driven to rotate through the second gear 204d, thereby causing the rotating rod 301 to rotate, which has a deceleration effect on the rotating rod 301.

[0052] Preferably, the planetary reduction mechanism 204 is arranged between the transmission rod 202 and the rotating rod 301, so that when the hollow ball 203 rotates one circle, that is, when the trigger rod 303c rises and falls once, the rotating rod 301 rotates half a circle or less to meet the light tracking needs of the photovoltaic panel M.

[0053] Preferably, the first limiting block 203c and the second limiting block 301a are both annular.

[0054] Preferably, a second sleeve 301b is fixed on the top of the rotating rod 301, which can cooperate with the body of the swing column 302 and be movably connected therebetween. The second sleeve 301b has a swing rod 302a and a second L-shaped plate 302c to limit the second sleeve 301b. Therefore, the swing column 302 can rotate with its own axis as the center.

[0055] When the rotating rod 301 rotates, it can drive the swing column 302 to rotate. The swing rod 302a is fixed on the outer wall of the swing column 302 and extends radially along the swing column 302. A ball head 302b is also fixed at the end of the swing rod 302a. The ball head 302b can extend into the annular cavity 303a inside the lifting ring 303. When the lifting ring 303 moves up and down, it can drive the swing rod 302a to swing, so that the swing column 302 rotates accordingly.

[0056] Preferably, a second L-shaped plate 302c is fixed at the end surface of the swing column 302, and the second L-shaped plate 302c is also divided into two plates, and the surface of one plate points to the end surface of the swing column 302. The surface of the other plate points to the axis of the swing column 302, and the photovoltaic frame 302d for supporting the photovoltaic panel M is fixed on the other surface of the plate. When the swing column 302 rotates, the pitch angle of the photovoltaic panel M changes accordingly.

[0057] Preferably, the lifting ring 303 is sleeved on the periphery of the rotating rod 301, and an annular cavity 303a is opened on the inner wall. The ball head 302b is tangent to the inner wall of the annular cavity 303a. Since the annular cavity 303a is deeper, even if there is some positional deviation during the swinging process of the ball head 302b, the pitch angle of the photovoltaic panel M can be changed.

[0058] An L-shaped rod 303b is fixed on the outer wall of the lifting ring 303, and the positioning rod 105 directly penetrates the crossbar part of the L-shaped rod 303b to ensure that the lifting ring 303 can perform lifting movement. A trigger rod 303c pointing to the O-shaped inclined groove 203b is also fixed at the end of the longitudinal rod of the L-shaped rod 303b.

[0059] Preferably, the trigger rod 303c passes through the strip groove 104, and the strip groove 104 can ensure that the lifting ring 303 does not rotate. When the hollow ball 203 rotates, the trigger rod 303c moves in the vertical direction along the track of the O-shaped inclined groove 203b.

[0060] When in use, first fix the containing box 101 by bolts, and then adjust the rotating rod 301 and the planetary reduction mechanism 204 to make the photovoltaic panel M face east. At this time, the trigger rod 303c should be located at the lowest position of the O-shaped inclined groove 203b.

[0061] When the sun rises, the first motor 201 starts to work, the transmission rod 202 drives the hollow ball 203 to start rotating with the connecting rod 202b as the rotation center. Under the deceleration of the planetary reduction mechanism 204, the transmission rod 202 rotates one circle, the hollow ball 203 also rotates one circle, and the rotating rod 301 rotates half a circle, that is, the photovoltaic panel M rotates from east to west, and the sun sets at this time. Under the action of the O-shaped inclined groove 203b, the trigger rod 303c at this time also moves from low to high, and then from high to low, corresponding to the process of the sun rising from the horizon to high altitude and then falling back to the horizon.

[0062] Specifically, the rotating rod 301 drives the photovoltaic panel M to rotate half a circle. At the same time, the lifting ring 303 drives the photovoltaic panel M to rise and then fall, corresponding to the movement trajectory of the sun.

[0063] Preferably, the trajectory of the sun's movement in each season is similar but different, and is a dynamic process. In summer, the daytime is longer and the sun is higher, while in winter, the daytime is shorter and the sun is lower. Therefore, the operation time of the first motor 201 should be consistent with the daytime. The time of sunrise and sunset can now be predicted, so the first motor 201 can accurately control the operation time.

[0064] As the season changes, the second motor 205 can be controlled to drive the worm 206 to drive the worm wheel 203d to rotate, so that the hollow ball 203 starts to rotate with the support rod 203a as the rotation center. At this time, the highest and lowest points of the O-shaped inclined groove 203b change. Figure 6 When rotating clockwise, the height difference increases, and when rotating counterclockwise, the height difference decreases to cope with the change in the height of the sun. Since the highest and lowest points of the O-shaped inclined groove 203b change, the corresponding stroke of the lifting ring 303 also increases or decreases accordingly, so the pitch angle range of the photovoltaic panel M during operation can be controlled. Under the premise that the photovoltaic panel M has a fixed stroke trajectory every day, it can also adapt to the light-chasing path throughout the year and improve the efficiency of photovoltaic power generation.

[0065] Preferably, the second motor 205 takes the number of days of the whole year as the operation cycle, and the setting is also simple and reliable. The cooperation between the worm 206 and the worm wheel 203d can ensure that the tilt angle of the hollow ball 203 is locked.

[0066] Preferably, on the second day, the photovoltaic panel M can be further rotated to the position of the previous day for reset, or rotated in the opposite direction for reset.

[0067] In summary, this design enables the photovoltaic panel M to change according to the curved trajectory of the sun under the drive of the first motor 201. It can also adjust the operation mode of the photovoltaic panel M according to different seasonal conditions and different running trajectories of the sun.

[0068] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
