[0035] The utility model provides a line and dynamic pulley control's heliostat, include: controller 13 is set up in the inner side bottom end of support plate 3, and the connecting mode between controller 13 and self rotating motor 2 is electric connection, and controller 13 still includes: motor 7, install in the inner side of support plate 3, and motor 7 is installed in the right upper side of sliding slot 6, and the connecting mode between motor 7 and controller 13 is electric connection, and motor 7 still includes: first pull rope 10, one end is connected in the top end of reflector 4, and the other end of first pull rope 10 is connected in dynamic pulley 8, and first pull rope 10 is around respectively set in fixed pulley 14 and motor 7, spring 11 is connected respectively on first pull rope 10, and spring 11 makes first pull rope 10 have elastic telescopic structure, and the rotation of motor 7 can drive first pull rope 10 to force and can pull the included angle between reflector 4 and support plate 3 to change, so that reflector 4 can have different angles to the reflection of sunlight, and using first pull rope 10 instead of rigid transmission can make the structure simpler, and the manufacturing cost is lower, and it is more convenient to use.

[0036] Working principle: when using the device, first according to Figures 1-4As shown, the rotation axis of the self-rotating motor 2 is also the target direction, and the height angle of the reflector 4 is controlled by the first pull rope 10 and the inelastic pull rope 12, and the light sensor 5 is synchronously controlled. In the initial position, the inelastic pull rope 12, the sliding groove 6 and the reflector 4 always form an isosceles triangle, the reflector 4 is perpendicular to the rotation axis of the self-rotating motor 2, and the angle a is formed between the reflector 4 and the sliding groove 6. The light sensor 5 is arranged in the middle of the edge of the mirror, and in the initial position, it is parallel to the reflector 4 and has the same angle a with the inelastic pull rope 12. One end of the first pull rope 10 is connected to the edge of the reflector 4, and the other end is connected to the movable pulley 8 through the motor 7 and the fixed pulley 14. One end of the inelastic pull rope 12 is connected to the light sensor 5, and the other end is connected to the bottom end of the sliding groove 6. The motor 7 can pull the first pull rope 10 back and forth to move the movable pulley 8 in the sliding groove 6, and at the same time, the spring 11 in the first pull rope 10 pulls the reflector 4. The movable pulley 8 presses the inelastic pull rope 12 against the bottom of the sliding groove 6. Therefore, the motor 7 can pull the movable pulley 8 back and forth, and at the same time, the reflector 4 is retracted and extended. Part of the inelastic pull rope 12 is pressed against the bottom of the sliding groove 6 by the movable pulley 8, and part of it pulls the light sensor 5, allowing the light sensor 5 to rotate at an angle, and allowing the reflector 4 to rotate at an angle. The other edge of the reflector 4 is pulled by the first pull rope 10 through the spring 11. In this balanced state, the rotation axis of the light sensor 5, the connecting shaft 9 of the reflector 4, and the contact point of the movable pulley 8 and the bottom of the sliding groove 6 always form an isosceles triangle. In this process, the length of the first pull rope 10 needs to change, and the spring 11 in the middle can meet the length change. The rotation axis of the self-rotating motor 2 is also the target direction, but here the first pull rope 10 is used to control the height angle of the reflector 4 and the angle of the light sensor 5, so that the change speed of the inclination angle of the light sensor 5 is twice that of the reflector 4. Thus, the sunlight vertically incident on the light sensor 5 is reflected by the reflector 4 and directed to the target, thus completing the use process of the heliostat controlled by the line and the movable pulley.

[0037] It is worth mentioning that the pull rope spring fixed pulley is not used here, but a torsion spring is used to turn the mirror to one side, and the inelastic rope pulls the other side of the mirror. In other ways, the movable pulley can also achieve the effect of this invention. The second scheme can also be used as a second-best alternative.

[0038] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
