[0002] A heliostat is an optical device that reflects light from the sun or other celestial bodies in a fixed direction. It is also called a heliostat and is usually used in the fields of solar power generation and solar thermal utilization. The angle rotation mechanism of the heliostat tracking device is one of its core components, which is used to adjust the angle of the heliostat to ensure that the sun's rays are always reflected on the target. The angle rotation mechanism is usually composed of a motor, a reducer, gears, chains, etc. The motor is used to provide power, the reducer is used to reduce the speed of the motor and increase the torque, the gears are used to transmit power and change the transmission ratio, and the chain is used to connect the gears and the heliostat.

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings. Example

[0022] like Figure 1-Figure 4 As shown, an angular rotation mechanism of a heliostat sun tracking device includes a base 1, a support column 2, a connecting rod 3, a mounting plate 4, a reserved hole 5, a reflector 6 and a rotating mechanism. A support column 2 is provided at the center of the top surface of the base 1, and connecting rods 3 are provided on both sides of the support column 2. A mounting plate 4 is fixedly installed at one end of the connecting rod 3 away from the support column 2. A plurality of reserved holes 5 are opened on the surface of the mounting plate 4. A reflector 6 is detachably installed on the surface of the mounting plate 4. The reflector 6 is normally inclined. A first bearing 7 is inserted at the center of the top surface of the base 1, a second bearing 9 is provided on one side of the first bearing 7, and the second bearing 9 is installed on the top surface of the base 1. The rotating mechanism includes a first gear disc 8, a support shaft 10, a second gear disc 11, a first bevel gear 12, a second bevel gear 13, a metal seat 14, a motor 15, a reducer 16, and a rotating shaft 17. The bottom end of the support column 2 is fixed at The first toothed disc 8 is fixedly installed on the inner wall of the first bearing 7 and the outer surface of the bottom of the support column 2. The second toothed disc 11 is meshedly connected to one side of the first toothed disc 8. The support shaft 10 is fixedly connected to the center of the second toothed disc 11. The bottom end of the support shaft 10 is fixed to the inner wall of the second bearing 9. The top of the support shaft 10 is fixedly installed with a first bevel gear 12. The second bevel gear 13 is meshedly connected to one side of the first bevel gear 12. A metal seat 14 is fixedly installed on the top surface of the base 1. A motor 15 is fixedly installed on the top surface of the metal seat 14. A reducer 16 is connected to the output end of the motor 15. The output end of the reducer 16 is rotatably matched with a rotating shaft 17. The end face of the rotating shaft 17 is fixed on the surface of the second bevel gear 13. A bearing frame 18 fixed to the top surface of the base 1 is provided between the metal seat 14 and the second toothed disc 11. The inner wall of the bearing frame 18 is fixedly connected to the outer surface of the rotating shaft 17.

[0023] The working principle of the above technical solution is as follows:

[0024] When it is necessary to adjust the angle of the use position of the reflector 6 to follow the sunlight position, the motor 15 and the reducer 16 are driven, and then the shaft 17 can be rotated at a reduced speed due to the rotation of the reducer 16. When the shaft 17 rotates, the second bevel gear 13 rotates and meshes with the first bevel gear 12. At this time, the first bevel gear 12 also rotates due to the meshing action of the second bevel gear 13. When the first bevel gear 12 rotates, the support shaft 10 rotates and rotates with the second toothed disc 11. When the second toothed disc 11 rotates, the first toothed disc 8 on one side starts to mesh and rotate, and then the support column 2 starts to rotate following the rotation of the first toothed disc 8. When the support column 2 rotates, the reflector 6 can be moved away from the original position for angle change.

[0025] In another embodiment, if Figure 2 and Figure 4 As shown, an adjusting cavity 19 is provided inside the support column 2, and adjusting sleeves 20 are fixedly installed on both sides of the support column 2, and the adjusting sleeves 20 are communicated with the adjusting cavity 19, the connecting rod 3 rotates on the inner wall of the adjusting sleeve 20, and the inner wall of the adjusting cavity 19 is rotatably matched with a rotating ball 21, the opposite ends of the two connecting rods 3 are fixed on the surface of the rotating ball 21, and the outer surface of the connecting rod 3 is sleeved with a positioning sleeve 22, and the end of the connecting rod 3 away from the rotating ball 21 is provided with a circumferentially distributed sliding groove 23, and the inner wall of the sliding groove 23 is slidably matched with a slider 24, the end of the slider 24 is fixed on one side of the positioning sleeve 22, and the end of the slider 24 away from the positioning sleeve 22 is fixedly installed with an anti-skid plug 25, the slider 24 and the anti-skid plug 25 are integrated and L-shaped, and the end face of the adjusting sleeve 20 is provided with six circumferentially distributed limit sockets 26, and the anti-skid plug 25 is inserted and matched with the limit socket 26.

[0026] After the reflector 6 is installed, the use surface needs to be adjusted. The connecting rod 3 can be directly rotated to make the rotating ball 21 rotate on the inner wall of the adjustment cavity 19. During the process, the connecting rod 3 will rotate on the inner wall of the adjustment sleeve 20. When the angle of the reflector 6 is adjusted to the normal use angle, the positioning sleeve 22 is pushed close to the adjustment sleeve 20. During the process, the slider 24 will slide on the inner wall of the slide groove 23, and then the anti-slip plug 25 can be inserted into the inner wall of the limit socket 26 as the slider 24 slides.

[0027] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
