Embodiment Construction

[0023] The present invention will be further described in conjunction with accompanying drawing:

[0024] A parabolic solar energy concentrator, the energy concentrator adopts a parabolic shape, and its equation is:

[0025] x a A + y b B = Z ,

[0026] Wherein A and B are constants, the value range of a and b is 1.65-1.75, and a and b can be equal or unequal.

[0027] Among them, A and B are constants, and the specific constants are determined according to the orbit of the sun at the geographical location where the solar concentrator is installed.

[0028] Such as image 3 As shown in the schematic diagram of this parabolic solar concentrator with figure 2 In comparison with the elliptical parabolic solar concentrator in the same depth, the area of ​​the parabolic solar concentrator is much larger t...

Abstract

The invention discloses a paraboloid solar energy concentrator which has an equation shown in the specification, wherein A and B in the equation are both constants, and the numeral range of a and b is 1.65-1.75. In the invention, a spherical solar heat energy converter is adopted, therefore, the sunlight reflection region is largened, and the solar energy utilization ratio is improved; the energy concentrator and a support seat are fixed through the support at a node and the stretch-draw of a cable, therefore, the support is stable; and furthermore, the cable has high strength and lighter weight, and the support seat adopts a spherical or hyperbolic-type support seat, therefore, the load-carrying capacity is good, and the shock resistance is strong.

Description

technical field [0001] The invention belongs to the technical field of solar energy collection, in particular to a parabolic solar energy concentrator. Background technique [0002] Among all kinds of energy, solar energy has the most abundant reserves, the widest distribution, and the cleanest. Solar energy is the energy with the most utilization potential for sustainable development of human beings. At present, solar cookers use reflectors to reflect sunlight and focus solar energy directly at their focal points. The reflector generally adopts the paraboloid of revolution and the paraboloid of ellipse. For example, the equation is: [0003] x a A + y b B = Z , A paraboloid where a=b=2. [0004] The diameter and depth of the above-mentioned parabolic concentrator have a fixed relationship. The lar...
