An L-shaped rod 10 is rotatably set on the top surface of the rear support frame 2 via a bearing seat 2. An installation plate 11 is horizontally fixed at the other end of the L-shaped rod 10. Light sensors are evenly fixed on the top surface of the installation plate 11. By setting the installation plate 11 with light sensors above the support frame 2, the system can adjust the angle of the heat collection plate 501 in real time according to the angle of sunlight.

[0036] A rain guide pipe 601 is vertically fixed on the bottom surface of the reflector plate 6. The rain guide pipe 601 is a flexible hose. A second heat collection pipe 602 is laid on the rain guide pipe 601. The front end of the second heat collection pipe 602 passes through the front support frame 2 and is connected to a second water supply pipe 9.

By setting the second heat collection pipe 602 inside the reflector plate 6, the solar thermal efficiency of the device is further improved.

[0037] In use, after moving the reflector plate 6 under the two L-shaped frames 4, pull open the C-shaped rod 705 so that the two movable plates 701 limit the left and right ends of the reflector plate 6, and cooperate with the two support frames 2 to limit the four sides of the reflector plate 6; then press the movable plate 701 down so that the toothed plate 708 at the bottom of the movable plate 701 and the movable toothed plate 710 are locked together, making the installation of the reflector plate 6 more stable. When it is necessary to replace or repair the reflector plate 6, pull the lever 712 outward to disengage the movable toothed plate 710 from the toothed plate 708, so that the movable plate 701 is quickly lifted. By setting the mounting plate 11 with the light sensor above the support frame 2, the system can adjust the angle of the heat collection plate 501 in real time according to the angle of sunlight.
