A heliostat mounted on an inner mounting frame (1) of a heliostat frame according to claim 2, characterized in that: It comprises a heliostat body (9), one end of which is inserted into the central cylinder (11), and the other end of which is overlapped on the outer ring body (13) and fixed by an arc-shaped fixing seat (15); The shape of the heliostat body (9) is set to be fan-shaped, an inner limit convex strip (91) is integrally formed on the inner cylindrical surface of the heliostat body (9), and an outer limit convex strip (92) is integrally formed on the outer cylindrical surface of the heliostat body (9); A side limiting convex strip (94) is integrally formed on one side of the heliostat body (9), and a limiting groove (95) that slidably cooperates with the side limiting convex strip (94) is provided on the other side.

9. A heliostat according to claim 8, characterized in that: The central cylinder (11) is provided with an annular groove (111) matching with the inner limiting convex strip (91), and the arc-shaped fixing seat (15) is provided with an arc-shaped groove (151) matching with the outer limiting convex strip (92); The arc-shaped fixing seat (15) locks the heliostat body (9) and the outer ring body (13) together through a fastener (153); the outer limit convex strip (92) is provided with a first bolt hole (93) for the fastener (153) to pass through, and the outer ring body (13) is provided with a second bolt hole (133) for the fastener (153) to pass through; A sliding block (152) is provided at the bottom of the arc-shaped fixing seat (15), and the sliding block (152) is slidably matched with the sliding groove (132) on the outer ring body (13).

10. A heliostat frame and a method for installing a heliostat, using a heliostat frame according to any one of claims 1 to 7 and a heliostat according to any one of claims 8 to 9, characterized in that: The following steps are involved: S1: driving the middle ring body (2) to rotate to an angle that is convenient for installing the heliostat body (9) through the second motor (41); S2: The installer inserts the front end of the heliostat body (9) into the annular groove (111) of the central cylinder (11), and then pushes the arc-shaped fixing seat (15) to slide along the slide groove (132) until the rear end of the heliostat body (9) is inserted into the arc-shaped groove (151), and then the heliostat body (9) and the outer ring body (13) are locked by the fastener (153), thus completing the installation of the first heliostat body (9); S3: driving the inner mounting frame (1) to rotate by means of the first driving mechanism (3) so that the next mounting position is located at the bottom, so as to facilitate installation by the installer; S4: The installer inserts the front end of the heliostat body (9) into the annular groove (111) of the central cylinder (11). During the inserting process, the side limiting convex strip (94) cooperates with the limiting groove (95) so that the two adjacent heliostat bodies (9) are locked together. Then, the heliostat body (9) and the outer ring body (13) are locked by the arc-shaped fixing seat (15), and the installation of the second heliostat body (9) is completed. S5: Complete the installation of all heliostat bodies (9) in sequence.
