These ropes can be connected with the swingle 206 at 204 back side of reflector.Swingle 206 is rotated in one direction can be with Rope is tightened up, is rotated in the opposite direction, the rope that releasably tightens up.Rope can be shortened or be lengthened to tightening up and discharging for rope Son bypasses the part at reflecting surface and the reflector back side, so as to increase or mitigate the tension force on the opposition of reflector 204 both sides.Swingle has Independent Motor drive and control system（Do not show in figure）.In instances, swingle 206 can add rotary shaft and by electronic Machine 209 drives.

Condenser can also be equipped with various sensors or feedback device (not shown) to provide condenser and environmental information Position, shape, operating parameter, the position of the sun, the direction of wind and speed, temperature, humidity, rain, snow, sand and dust such as condenser Deng.The signal of sensor or feedback device can send control system to by wired or wireless communication.

The adjustment in 202 direction of reflecting surface can change the position of focal line.The adjustment of 202 shape of reflecting surface can change reflecting surface 202 focal length.Therefore, in conjunction with the two adjustment modes, condenser can make solar light focusing to target receiver.

Give an example, in a particular instance, reflecting surface 202 in parabolic troughs form, if incident illumination parallel to The focal plane (plane crosses the summit of focal line and groove) of parabola groove, i.e., angle of incidence is zero, then reflected sunlight can be focused on On the focal line of parabola groove, receptor is installed at focal line.If the angle of incidence of incident illumination is pressed from both sides in 60 degree with the focal plane of parabola groove Angle, if the direction of groove does not shift 60 degree, by the focusing length of reflected sunlight slightly shorter than the distance to groove summit, then reflects Sunlight will not be focused onto on the focal line of groove.In this patent, parabolic reflector 202 can be adjusted, for example, tune up focal length.Adjustment Afterwards, angle of incidence is the position that 60 degree of incident illumination can be gathered in that a target receiver is located.

Therefore, by the deformation of 202 parabola groove of reflecting surface or adjust its focal length and second focal length changed to from first focal length, Still same position can be focused on relative to parabola groove focal plane in the sunlight that 60 degree i.e. angle of incidence is 60 degree.

The concentration ratio of reflecting surface is with regard to solar angle and the function of reflecting surface width and target focal length.For example, focus on Width is 0.04m, and the angle of incidence of sunlight is 60 degree, and the focal length of reflecting surface is 8m, and width 2m, concentration ratio are 50 (2m/ 0.04m)；For another example, focal width 0.01m, the angle of incidence of sunlight is 60 degree, the focal length 8m of reflecting surface, width 1m, then optically focused Rate is 100（1m/0.01m）, for another example, focal width is 0.003m, and the angle of incidence of sunlight is 60 degree, and the focal length of reflecting surface is 8m, width 0.5m, concentration ratio are 166 (0.5m/0.003m).
