Background
Many people have already achieved research results on the problem that sunlight with a larger area is reflected to a heat collection device by utilizing a light-gathering reflector to enhance the heat collection effect and improve the temperature of a medium in the heat collection device, some reflector plates adopt a V-shaped reflector plate, some reflector plates adopt a barrel-shaped reflector plate with a cross section line being an arc, some reflector plates adopt an arc-shaped reflector plate with a cross section line being connected by arcs with different curvature radiuses, and some reflector plates adopt an involute line with a cross section line being a circle.
As the non-tracking light-gathering reflecting plate has large change of the incident angle of sunlight, a large amount of sunlight which cannot be reflected to a heat-gathering device still cannot achieve satisfactory light-gathering effect, and a part of strong light is usually leaked out while some weak light is captured.

The invention adopts a plurality of segments of parabolas to form a reflecting surface sectional line of a light-gathering reflecting plate, the incident rays of the sun parallel to any parabolic axis can be gathered to the focus of the corresponding parabola, because the heat-collecting element arranged at the pole (also at the focus of each parabola) has a certain volume, the incident rays of the sun with an included angle with the corresponding parabolic axis smaller than a certain value can be reflected to the heat-collecting element by the reflecting surface of the parabolic segment, the light-gathering reflecting plate gathers relatively strong incident rays in a certain time range before and after noon to obtain the best light-gathering effect relative to the light-gathering reflecting surfaces of other shapes, the segments of the parabolas are different in distance from the focus, so the time for gathering the sunlight in the certain time range before and after noon is different in initial time, the incident rays of the sun arriving at the reflecting surface of each parabolic segment are all reflected and gathered to the surface of the heat-collecting element in the whole time with relatively strong sunlight intensity, the heat-gathering efficiency is higher, and an expensive tracking device is unnecessary. The space curved surface is used as a light reflecting and condensing surface, and a certain amount of relatively weak solar rays cannot be condensed on the heat collecting element in one day because the space curved surface is not tracked, but the space curved surface is used as the non-tracking light reflecting and condensing surface to have the best light condensing effect theoretically. The invention can be used as a light-gathering reflector of various non-tracking solar heat collectors, a light-gathering reflector in heat collecting pipes, a light-gathering reflector of non-tracking solar cookers and the like.
The space curved surface may have two structures, one of which is formed by stretching the sectional line in a direction perpendicular to a plane in which the sectional line is located. The focus of each sectional line is stretched to form a straight line, and a solar heat collecting pipe can be arranged along the straight line to form a non-tracking solar heat collector. And secondly, the space curved surface is formed by rotating the section line, and the rotating shaft is a symmetrical shaft of the section line. Each section line has a common focus (polar point), and a heat collecting element can be arranged on the focus to manufacture the non-tracking solar cooker.
