Abstract
The invention discloses a novel solar secondary reflecting surface and a supporting device thereof. The novel solar secondary reflecting surface is of a composite parabolic structure, wherein the composite parabolic structure is characterized in that a top involute is combined with a side parabolic surface; and an abduction angle of the top involute is greater than a standard involute by 1-2 degrees. The supporting device of the novel solar secondary reflecting surface comprises a support composite parabolic panel, supporting side panels and secondary reflecting external enclosing plates, wherein the support composite parabolic panel is fixed at the upper part of a secondary reflecting surface and is matched with the secondary reflecting surface in shape; the supporting side panels are fixed on two sides outside the support composite parabolic panel; the secondary reflecting external enclosing plates are fixed outside the supporting side panels to form a full-enclosing structure; and support upper plates are fixed at the tops of the supporting side panels and the tops of the secondary reflecting external enclosing plates. The collision and the contact between heat collecting tube glass outer tubes and the secondary reflecting surface are avoided, the loss of the reflecting surface is avoided and the condensing and reflecting functions of the secondary reflecting surface are ensured, and thus the light-heat conversion efficiency is increased. Meanwhile, the novel solar secondary reflecting surface has the advantages of simpleness in manufacturing and mounting, accuracy in forming and remarkable effect.
Description
Technical field
The present invention relates to technical field of solar utilization technique, be specifically related to a kind of new type solar energy secondary reflection face and bracing or strutting arrangement thereof.
Background technology
The energy resources reserves of China allow of no optimist, and per capita resources is not abundant.Many places lack the conventional energy resource resource, but solar energy resources is abundant.For improving solar energy thermal-power-generating efficient, need to improve the performance and the thermal transition efficient of each assembly of solar energy thermal-power-generating, parts.Line focus secondary reflection device is greatly to improve Salar light-gathering ratio and light-thermal conversion efficiency.Composite parabolic shape and fixed structure in the secondary reflection face of using for solar energy thermal-power-generating, state, inside and outside research are less, need carry out primary study and development.
At present for improving line-focusing solar heat generating temperature; The general glass-metal vacuum heat collection pipe that adopts; So; For example must adopt the secondary reflection device, the reverberation of primary event device is carried out secondary focusing as the hot generation technology of Fresnel solar energy, could the maximized solar radiation energy that utilizes.Have only the metal inner pipe of thermal-collecting tube to be positioned at the along of secondary reflection minute surface; The maximized absorption solar radiation energy of ability; But the general outer glass pipe of glass-metal vacuum heat collection pipe is than big many of metal inner pipe radius; Outer glass pipe will touch on the secondary reflection device of standard, and inconvenience is made and installed.Generally take to dwindle the way of glass-metal vacuum heat collection pipe radius, solve this type of problem.
Summary of the invention
For solving the problem that exists in the above-mentioned prior art; The object of the present invention is to provide a kind of new type solar energy secondary reflection face and bracing or strutting arrangement thereof; Secondary reflection face shape of the present invention can be avoided the collector tube glass outer tube to bump with the secondary reflection face and contact; Avoid the reflecting surface loss, guaranteed the optically focused reflection function of secondary reflection face, thereby improve light-thermal conversion efficiency.
For achieving the above object, the technical scheme that the present invention adopted is:
A kind of new type solar energy secondary reflection face, said secondary reflection face 2-1 is a composite paraboloid structure, and said composite paraboloid structure is involute and side parabolic combined at top, and the exhibition angle of said involute is bigger by 1 than the exhibition angle of standard involute
