The basic structure of the solar thermal collector plate includes a coating 13 , a transparent partition 14 , a transparent cover 15 , a thermal insulation layer 16 and a shell 17 . Referring to Fig. 4 for the internal structure of the solar thermal collector plate, the coating 13 covers the upper surface of the bottom heat insulation layer 16. The coating material has a high solar short-wave radiation absorption rate and a low long-wave thermal radiation emissivity, and can absorb as much solar energy as possible. hot. The surface of the coating 13 is covered with a layer of extremely thin transparent partition 14 with minimal thermal resistance, the purpose is to separate the coating from the water to be heated, prevent the coating material from polluting the water, and play a waterproof role. The water to be heated passes into the heat collecting plate and is heated in the space interlayer between the transparent partition 14 and the transparent cover 15 . The transparent cover 15 adopts double-layer hollow flat glass, which has three functions, one is to project solar radiation on the heat-absorbing plate; the other is to isolate water and outside air, and has the function of heat preservation; , to prevent the coating from dissipating heat to the surrounding environment through long-wave radiation after the temperature rises. The heat insulation layer 16 is installed on the bottom of the solar thermal collector plate, and the purpose is to suppress the heat dissipation of the coating and the water body to the surrounding environment through conduction. The shell 17 (rectangular cavity surrounded by four plates, front, rear, left, and right, without bottom plate and cover plate) is a part to protect and fix the transparent cover plate 15 and the heat insulation layer 16 in the heat collecting plate, and the transparent cover plate 15 constitutes a rectangular cavity. The cover plate, the coating 13, the transparent partition 14 and the heat insulating layer 16 together form the bottom plate of the rectangular chamber. Each heat collecting plate 1 includes two water inlets and two water outlets.

The cold water in the thermal insulation water tank 2 flows out from the lower circulation pipe 11, and is affected by the density difference and the height difference, flows through each solar collector plate 1 sequentially from bottom to top, and returns to the thermal insulation water tank 2 through the upper circulation pipe 12 after being heated one by one. This cycle goes on and on, constantly heating the water in the thermal insulation water tank. The thermal water tank is provided with a hot water pipe, and the heated water flows out through the hot water pipe for various occasions that require hot water. The heat preservation water tank is connected with the water replenishment tank through the replenishment pipe at the same time, when the water in the heat preservation water tank is reduced due to use, it can be replenished through the water replenishment tank.

Rotate hand crank 6 when needing daylighting, output rotating shaft drives steel wire stay cord 7 and pulls the bottom slide block 5 to move upwards. The hinge 9 between the bottom group of solar heat collecting plates is rotated towards the prescribed direction under force, so that the bottom group of two solar heat collecting plates begins to fold. When the corresponding sliders of the lower group touch the sliders of the upper group, the lower sliders push the upper sliders to slide upwards, and the second group starts to fold according to the same principle, thus making each solar collector plate 1 from Stack and rise successively from bottom to top until being guided to the rear fixed position on the bay window top by guide rail 4. When sunshade is required, turn the hand crank 6 in the opposite direction, and the steel wire rope 7 is loosened. The solar collector plate 1 descends from the top along the guide rail 4 in turn by gravity, and returns to the vertical state to form a sunshade surface. At the same time, it absorbs solar energy and water heating. Since the solar collector plates 1 are connected by flexible pipes, they will not be disconnected. If you are worried that the connecting force is not enough, you can increase the flexible wire connection between the solar collector plates 1 .
