Lens greenhouse light target linked solar collecting device

Abstract

The invention discloses a lens greenhouse light target linked solar collecting device. The lens greenhouse light target linked solar collecting device comprises a greenhouse support and a greenhouse frame. The support and the frame form the skeleton of the greenhouse. The frame is provided with a roof. The roof is spliced by a long-strip Fresnel lens. A light target is arranged below the frame. The Fresnel lens corresponds to the light target. The sunlight forms a spotlight zone through the Fresnel lens to be focused on the light target. The light target is arranged on parallel supports. Each of the parallel supports comprises a warp slide rail. Both ends of the light target are fixed on the warp slide rail. The warp slide rails are arranged on the fixed frame and are connected with the fixed frame through guide rail pairs. Weft slide rails are arranged below the fixed frame. The weft slide rails are connected with the fixed frame through the guide rail pairs. A sunshine tracking mechanism is connected with the roof, the light target and the parallel supports respectively. The parallel supports moves in the warp and weft directions under the action of the sunshine tracking mechanism so that the light target can track the spotlight zone of the Fresnel lens.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a solar energy collection device. Background technique [0002] Solar energy is widely distributed, inexhaustible and inexhaustible clean and environmentally friendly energy. Today, when the problem of energy shortage is becoming more and more prominent, the development and utilization of solar energy has become the focus of realizing the sustainable development of energy. Solar thermal and solar photovoltaic are the hot spots of research and application in recent years, but there is always a problem in solar energy application, which is the energy density of solar energy. It's too low, and the sun is still running all the time, making it difficult to collect solar energy on a large scale and economically. People have thought of a lot of methods, such as trough concentrator, heliostat concentrator, and dish concentrator, such as Chinese patents CN1004114093C, CN1687669A, CN101368764A...

Today, the problem of energy scarcity is becoming more and more prominent, and the development and utilization of solar energy has become the focus of achieving sustainable energy development. Solar thermal and solar photovoltaic are the hot spots of research and application in recent years, but there has always been a problem in the application of solar energy, which is the energy density of solar energy. Too low, and the sun is running non-stop, making it difficult to collect solar energy on a large scale and economically

People have thought a lot of ways, have trough type concentrator, have heliostat concentrator, have disc concentrator, as Chinese patent CN1004114093C, CN1687669A, CN101368764A, CN1779381A, CN100460320C, CN101371369A, CN1143999C, CN1677012A etc., this The three types of devices all have a common feature, they track the sun by rotating the mirror, the parts involved in the movement are bulky, consume a lot of energy, and operate outdoors all the year round, withstanding wind and rain, high equipment requirements and high cost , and a large amount of maintenance

There are also fixed reflective condenser moving light targets, such as Chinese patents CN101609853A, CN201466042U, CN1263241A, etc., which have solved some problems to a certain extent, but these products have low weather resistance of fixed reflective condenser moving light target mode, inconvenient cleaning and maintenance, and The structure is complex and the cost is relatively high, which is not conducive to promotion
