DETAILED DESCRIPTION

[0018] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0019] like Figure 1-3 As shown, a distributed centralized power supply device includes: a base plate 1, the upper end surface of the base plate 1 is provided with a groove, a threaded rod 4 is rotatably connected in the groove, a motor 2 is fixedly arranged on the lower end surface of the base plate 1, and the output shaft of the motor 2 is detachably connected to the threaded rod 4.

[0020] The specific way in which the output shaft of the motor 2 is detachably connected to the threaded rod 4 is as follows: the interior of the threaded rod 4 is hollow, the output shaft of the motor 2 passes through the base plate 1 and one side of the threaded rod 4 and extends into the interior of the threaded rod 4, and corresponding mounting holes are provided on the threaded rod 4 and the output shaft of the motor 2, and an insertion rod 16 is provided at the overlapping part of the threaded rod 4 and the output shaft of the motor 2, and the insertion rod 16 is inserted into the corresponding mounting holes of the threaded rod 4 and the output shaft of the motor 2 to fix the threaded rod 4 and the output shaft of the motor 2, and the insertion rod 16 is removed from the mounting holes on the threaded rod 4 and the output shaft of the motor 2, and the threaded rod 4 can rotate independently.

[0021] A main solar panel 9 is fixedly arranged above the bottom plate 1, and a fixing block 10 is fixedly connected to the lower end face of the main solar panel 9. The top end of the threaded rod 4 is rotatably connected to the inside of the fixing block 10. Both sides of the main solar panel 9 are rotatably connected to extended solar panels 7. The outer side of the threaded rod 4 is threadedly connected to a slider 6. Both sides of the slider 6 are rotatably connected to first connecting rods 8. The number of the first connecting rods 8 is the same as the number of the extended solar panels 7. The end of the first connecting rod 8 away from the slider 6 is rotatably connected to the lower end face of the corresponding extended solar panel 7.

[0022] The output shaft of the motor 2 is connected and fixed to the threaded rod 4, and the motor 2 is started. The output shaft of the motor 2 drives the threaded rod 4 to rotate, so that the slider 6 moves in the vertical direction. The slider 6 drives the corresponding extended solar panel 7 to rotate through the first connecting rod 8, so that the extended solar panel 7 is opened with the main solar panel 9 as the center, so that the sun can better shine on the surface of the main solar panel 9 and the extended solar panel 7.

[0023] The upper end surface of the base plate 1 is symmetrically fixedly connected with a support rod 3, and a double-headed screw rod 14 is rotatably connected between the two support rods 3. The two ends of the outer surface of the double-headed screw rod 14 are respectively provided with threads of opposite rotation directions, and the two ends of the outer side of the double-headed screw rod 14 are threadedly connected with a moving block 11. A fixing hole is provided on the side of the threaded rod 4, and the double-headed screw rod 14 passes through the fixing hole. One end of the double-headed screw rod 14 passes through one of the support rods 3 and is fixedly connected with a handle 15.

[0024] A mounting ring 5 is sleeved on the outside of the threaded rod 4 and below the double-headed screw 14. There is a gap between the inner ring of the mounting ring 5 and the outer side of the threaded rod 4. The outer side of the mounting ring 5 is threadedly connected to a plurality of screws 13, and one end of the screw 13 can contact the outer side of the threaded rod 4.

[0025] A second connecting rod 12 is rotatably connected to the upper surface of the mounting ring 5 near the front, and another second connecting rod 12 is rotatably connected to the upper surface of the mounting ring 5 near the rear. The number of the second connecting rods 12 is the same as the number of the moving blocks 11, and the second connecting rods 12 are rotatably connected to the lower end surfaces of the corresponding moving blocks 11.

[0026] When it is necessary to fine-tune the rotation angle of the extended solar panel 7, the plug rod 16 is removed from the mounting holes on the threaded rod 4 and the output shaft of the motor 2, and the output shaft of the motor 2 is separated from the threaded rod 4, so that the threaded rod 4 can rotate independently, and then the screw rod 13 is rotated so that one end of the screw rod 13 can contact the outer side of the threaded rod 4, and the threaded rod 4 and the mounting ring 5 are fixed, and then the handle 15 is turned, and the handle 15 drives the double-headed screw rod 14 to rotate, so that the two moving blocks 11 move away from each other or move closer to each other, and the two moving blocks 11 move away from each other. When the two moving blocks 11 are separated, the two moving blocks 11 drive their respective second connecting rods 12 to rotate clockwise, and the two second connecting rods 12 work together to drive the mounting ring 5 and the threaded rod 4 to rotate clockwise as a whole. When the two moving blocks 11 are close to each other, the two moving blocks 11 drive their respective second connecting rods 12 to rotate counterclockwise, and the two second connecting rods 12 work together to drive the mounting ring 5 and the threaded rod 4 to rotate counterclockwise as a whole. When the threaded rod 4 rotates clockwise or counterclockwise, it drives the slider 6 to rise or fall, thereby fine-tuning the rotation angle of the extended solar panel 7.

[0027] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
