Problems solved by technology

[0002] Existing concentrating reflectors such as trough parabolic mirrors, butterfly reflectors and other reflectors have only one focal point, and can only focus when the sunlight is parallel to its focal line. When the angle is high, it cannot focus. In order to focus the sunlight, the reflector must always face the sun. The cost of tracking drive and bracket is very high, which affects the utilization of solar energy.

Embodiment Construction

[0059] figure 1 It is a local schematic diagram of the above-mentioned curved mirror, X and Y are two directions of Cartesian coordinates respectively, and the curvature of the curved surface in the X and Y directions can be the same or different, preferably the same; figure 2 It is a schematic diagram of the end of the small arc surface of the arc mirror, and R is the radius of the circle tangent to it in the figure; image 3 It is a schematic diagram of the sunlight reflection of a section perpendicular to the Y direction of the arc mirror. The arc shape of the section makes the incident sunlight reflect to a circular track tangent to a point on the arc mirror no matter from any angle. On or near the garden arc, there can be many kinds of arc shapes, one of which is a preferred arc shape The above-mentioned X and Y are respectively the coordinates of the curve in the plane coordinate system, and R is the radius of the above-mentioned garden arc, and R is preferably one ...

Abstract

The invention discloses a reflecting mirror and a light concentrating and energy storing device and belongs to the field of solar energy utilization. The invention discloses the reflecting mirror which can be fixed on the ground, solar light is enabled to be focused no matter what angle the solar light is incident at, a secondary light concentrating system is mounted on a focal point and a focal line, solar light can be concentrated on a point-like or linear zone after going through the secondary light concentrating system, a triple reflection mirror is mounted in the point-like or linear zone, the solar light is enabled to be reflected on a receiver positioned on or under the ground, and solid state or liquid state mediums positioned in the receiver can be used for energy storing.

Description

technical field [0001] The invention relates to a reflecting mirror and a light concentrating and energy storage device, belonging to the field of solar energy utilization. Background technique [0002] Existing concentrating reflectors such as trough-type parabolic mirrors, butterfly reflectors and other reflectors have only one focal point, and can only focus when the sunlight is parallel to its focal line. When the angle is lower, the focus cannot be achieved. In order to focus the sunlight, the reflector must always face the sun. The cost of tracking drive and bracket is very high, which affects the utilization of solar energy. [0003] The purpose of the present invention is to invent a reflector fixed on the ground, no matter how the incident sunlight moves, it can be concentrated into a point-shaped or linear or narrow-band focal point or focal line with this mirror, and the focusing Light and energy storage devices. Contents of the invention [0004] For realizin...
