Embodiment Construction

[0018] The key to this invention is to "steer" concentrated sunlight where we need it. The most critical first step is to turn the sunlight at the focus of the "solar cooker" into parallel light. Parallel light can be reflected by a plane mirror to change the light path.

[0019] The characteristics of a paraboloid of revolution are known: parallel rays of light parallel to the symmetry axis of the paraboloid of revolution are reflected by the mirror and focus on a point. i.e. focus. Conversely, the rays passing through the focus become parallel rays parallel to the axis after being reflected by the rotating paraboloid. The original solar cooker used the former, and we mainly emphasize the latter. The former condenses sunlight into a single point, while the latter turns the light into parallel light again. Therefore, the "concave turning head" is also a rotating parabolic mirror. It is just that it is different from the size and curve equation of the concentrating parabol...

Abstract

The invention relates to a system for turning focused sunlight spots into parallel light capable of being transmitted at high density in any direction. At present, solar energy is mainly utilized in two modes, namely focusing sunlight and directly focusing heat, and utilizes solar panels to convert into electric energy. A solar cooker technology is an ideal technological case for focusing sunlight, but has lower power and can only work close to a focus so that the utilization of the solar energy and the development of a solar energy utilization enterprise in a focusing mode are limited. Sunlight at the focus in the solar cooker technology can be transferred to an indoor point for indoor watering and cooking, and the process can be repeated to transfer sunlight in other places to the point so as to multiply the power until limitless multiplication, therefore, sunlight transfer at the solar cooker focus turns to be a key. A half of a revolving paraboloid (namely a concave light-transferring head) solves an initial problem of transferring the sunlight at the focus and converts the focused sunlight at the focus into parallel light rays which can be parallel to a principal axis and can randomly change directions, and afterwards, a flat mirror is utilized to reflect the parallel light rays into the point. The focusing mode collects high energy and finally realizes solar power generation.

Description

Technical field: [0001] solar energy, energy, energy conversion Background technique: [0002] At present, the use of solar energy in the world is mainly based on the use of solar panels. It is slow to develop because of its high price and low conversion rate. And solar cooker technology is also struggling in its more than 50 years of development history because of its low technical content. The invention cleverly utilizes the original concentrating technology of the solar cooker to transfer the condensing focus of the solar cooker to any position in the room, which can not only open the cooker indoors but also increase the power several times and dozens of times, and can make full use of the solar energy to boil water. , heating, cooling, power generation. The solar energy is converted into electric energy without the use of solar panels, creating a precedent for converting solar energy into thermal energy, thermal energy into mechanical energy, and mechanical energy int...
