Embodiment 1
[0039] This embodiment provides a multi-point surface shape automatic adjustment system for heliostats, including a control system 2 and a flexible adjustment unit 1. There are multiple flexible adjustment units 1, and the multiple flexible adjustment units 1 are electrically connected to the control system 2. signal connection;
[0040] The flexible adjustment unit 1 is fixedly connected with the mirror surface of the heliostat, the flexible adjustment unit 1 is used to adjust the surface shape of the heliostat, and the control system 2 is used to calculate and control each flexible adjustment according to the curvature of the mirror surface required by the heliostat. The amount of displacement of the unit 1 makes the curvature of each mirror 4 constituting the heliostat reach the target value.
[0041] The multi-point surface shape automatic adjustment system of the heliostat provided by the present invention can adjust the surface shape of the heliostat by using the flexibl...
Embodiment 2
[0043] On the basis of Embodiment 1, this embodiment provides a multi-point surface shape automatic adjustment system for heliostats. The flexible adjustment unit 1 includes a driver, a telescopic rod 102 and a displacement sensor. The telescopic rod 102 can Driven by the motor, it expands and contracts in the vertical direction, and the top of the telescopic rod 102 is provided with a mirror fixing device, and the displacement sensor is installed on the driver or the telescopic rod 102 .
[0044] The ultra-thin glass used in the heliostat is elastic and can be deformed under the action of an external force. The present invention uses a telescopic rod 102 to act on the reflector 4, and the coordinate point on the glass is adjusted to The target position, and stay at the target position, realize the positioning of the coordinate points on the mirror, and complete the adjustment of the surface shape.
[0045] The driver adopts a motor 101, and the displacement sensor is a rotary...
Embodiment 3
[0048] On the basis of Embodiment 1, this embodiment provides a multi-point surface shape automatic adjustment system for heliostats. The heliostats are installed in a positioning frame 3, and the positioning frame 3 includes a main support beam 301 and an auxiliary The supporting truss 302, the auxiliary supporting truss 302 is fixed on the main supporting beam 301 and both are vertically arranged.
[0049] Such as figure 1 As shown, there are multiple main support beams 301 and auxiliary support trusses 302, which are vertically intersected and divided into multiple frames to position the polygonal mirrors 4 that make up the heliostat. Such as figure 2 As shown, when installed, the top of the telescopic pole 102 passes through the auxiliary support truss 302 .
