specific Embodiment approach 1
[0026] Specific implementation mode one: combine figure 1 Illustrate this embodiment, the rotary solar concentrating method based on Cassegrain reflection principle described in this embodiment, it comprises the following steps:
[0027] Step 1: Establish a rotating Cassegrain aggregation system:
[0028] Set the quadratic hyperboloid 2 and the primary paraboloid 1 to share a focal point, arrange the receiving surface 3 at the conjugate focal point of the quadric hyperboloid 2, and the focal ratio of the primary paraboloid 1 needs to be less than or equal to 0.25;
[0029] Step 2: Rotate the quadratic hyperboloid 2 of the rotating Cassegrain aggregation system around the primary paraboloid 1, and then obtain the structural parameters of the quadratic hyperboloid 2 according to the position to be set on the receiving surface 3;
[0030] Step 3: According to the structural parameters of the quadratic hyperboloid 2 obtained in step 2, under the condition that the quadratic hyper...

[0032] Specific embodiment 2: This embodiment is a further limitation of the rotating solar concentrating method based on the Cassegrain reflection principle described in the specific embodiment 1. In step 2, the quadratic hyperboloid of the rotating Cassegrain concentrating system 2 rotate around the primary paraboloid 1, and then obtain the structural parameters of the quadratic hyperboloid 2 according to the position to be set on the receiving surface 3:
[0033] First, according to the coordinates of the center position of the receiving surface 3 as (x 0 ,y 0 ), the angle of rotation of the quadratic hyperboloid 2 around the primary paraboloid 1 is α, and the α=arctan (x 0 / (f-y 0 ));
[0034] Then, determine one of a or b of the quadratic hyperboloid 2 according to actual needs;
[0035] then according to a 2 +b 2 =(x 0 2 +y 0 2 ) / 4, find the other of a or b;
[0036] According to said α, a and b at last, determine the surface equation of quadratic hyperboloid ...

[0040] Specific embodiment three: This embodiment is a further limitation of the rotary solar concentrating method based on the Cassegrain reflection principle described in specific embodiment two. In step three, the quadratic hyperboloid 2 calculated according to step two Structural parameters, under the condition that the quadratic hyperboloid 2 in the rotating Cassegrain gathering system can receive all the concentrated rays of the focus, solve the rotation angle of the quadratic hyperboloid 2 around the primary paraboloid 1 based on the principle of geometric optics The method for the maximum value is:
[0041] Calculate the maximum value α of the counterclockwise rotation angle α of the quadratic hyperboloid 2 around the first paraboloid 1 according to the following formula max :
[0042] P 2 ( cos ...
