Description

Portable Fresnel light-gathering range
Technical Field
The invention relates to a Fresnel light-gathering stove, in particular to a box-type portable Fresnel light-gathering stove which can be opened and folded.
Background
The light-gathering solar cooker is characterized by that after the incident sunlight with large area is reflected by condenser, it can produce hot light mass, and the hot light mass can be focused on the bottom of cooker so as to meet the cooking requirements. The key part of the light-gathering stove is a light-gathering lens, and the light-gathering stove not only has the selection of mirror surface materials, but also has the design of geometric shapes. The most common reflective mirror is a silver-plated or aluminum-plated glass mirror, and also has an aluminum polished mirror surface and a polyester film aluminum-plated material.
The mirror design of the light-gathering solar cooker mostly adopts the light-gathering principle of a rotating paraboloid. A surface obtained by mathematically rotating a parabola one turn around a principal axis is called a "paraboloid of revolution". If a beam of parallel light is emitted to the paraboloid along the main axis and meets the reflection of the paraboloid, the light rays are reflected to the position of the focal point in a concentrated manner, and then the effect of light condensation or focusing is formed. When the energy-saving heating device is used as a light-gathering stove, a coke surface is required to be formed at the bottom of a pot to achieve the purpose of heating. According to the experience of popularizing a light-gathering stove in China, a light-gathering solar stove with the power of 500-700 watts is designed, and the light-gathering area is about 1.5-2.0 square meters generally. The individual large steam light-gathering stove can also be regarded as a light-gathering solar stove, but the light-gathering area is large, and some of the light-gathering areas are more than 5 square meters.
The concentrating solar cooker adopts a rotating paraboloid reflector, and also adopts a reflector which divides the paraboloid into a plurality of sections and has a focus, which is called as a Fresnel lens in optics, and the Fresnel lens is also made into a continuous spiral type reflecting strip sheet. The mirror surface of the light-gathering solar cooker is formed by integral hot bending of glass, and also is formed by sticking broken glass of common glass lenses on a designed bottom plate or pasting an aluminized polyester film with high light reflection rate on the bottom plate. The bottom plate can be made of cement or made of iron sheet and calcium plastic materials. The reflector can also be made by directly polishing with an aluminum plate and coating with an anti-oxidant. The frame body of the light-focusing solar cooker is made of metal pipes by bending, the height of the pot support is moderate, the operation is convenient, and the elevation angle and the azimuth angle of the mirror surface can be flexibly adjusted. In order to move conveniently, two small wheels can be arranged at the bottom of the frame, but the stability of the oven body must be ensured. In windy places, the light-gathering stove is required to resist wind and fall. The wind-proof cover can be added on the pot wall to reduce the power drop of the pot due to the influence of wind. Some light-focusing cookers are equipped with trackers that automatically track the sun, but this is generally believed to increase the cost of the entire cooker.
The existing Fresnel light-gathering range is made up by cutting metal or plastic plate into individual circular or spiral strips with different radiuses as reflecting base surface and sticking film reflecting material on the reflecting base surface. The ring surfaces form different inclination angles by adopting cushion blocks. The ring surfaces may also be connected together by a metal frame. However, the inclination angles of the rings of the Fresnel light-gathering stove have large manufacturing errors, the structure is rough, the manual manufacturing process is backward, the rings cannot be folded structurally, the rings are difficult to store and carry, and the Fresnel light-gathering stove is not suitable for industrial production.
Therefore, it is obvious that the above-mentioned existing fresnel light-gathering stove still has inconvenience and defects in structure and use, and further improvement is needed. In order to solve the problems of the fresnel focus, the relevant manufacturers have tried to solve the problems without diligent effort, but it has not been known that suitable designs have been developed and completed for a long time, and general products have no suitable structures to solve the problems, which is obviously a problem that the relevant manufacturers want to solve.
In view of the above-mentioned shortcomings of the existing fresnel light-focusing range, the inventor of the present invention has made active research and innovation based on the practical experience and professional knowledge of many years of design and manufacture of such products, and by using the theory, in order to create a novel structure of portable fresnel light-focusing range, which can improve the existing fresnel light-focusing range and make it more practical.
