Solar energy is a kind of renewable energy sources of huge and environmentally safe, and is inexhaustible, because of use fossil energy emission greenhouse gas, befouling environment and fossil energy will exhausted situation under, the utilization of solar energy is extremely important.Present many countries have turned one's attention to nuclear energy once more, but the cost height of nuclear energy, and potential harmfulness is big, and uranium ore also is limited.

Solar energy can be described as human ultimate energy, drops into much examinations that all is worth repaying in the research and development of its utilization, the hydraulic energy that has now developed, wind energy. tidal energy, biological energy source, fossil energy etc. all are the forms of expression of solar energy.Here said solar energy utilization is meant the direct utilization to solar energy.

At present, the conversion using mode of solar energy has light-heat, light-electricity conversion and photochemistry conversion.In light-thermal conversion,, all can only be disposable application, can not use and store as secondary energy based on the application and the research of solar water heater, solar range, solar energy heating agent air-conditioning etc.; With the research of photovoltaic cell be applied as the master, electric transferable application also can be by batteries to store energy and brine electrolysis production Hydrogen Energy in the conversion of light-electricity, but the technology content of photovoltaic cell is high, cost of production is also high, and is not high to the utilization ratio of sunlight, so the popularization and application difficulty is big.Because the energy density of sunlight is little, problems such as the collection of solar energy, the conveying of heat, storage, heat exchange have to be solved, restricted the utilization of solar heat conversion, insult at German's cloth and all only to have mentioned contents such as photovoltaic cell about energy part in " 100 kinds of variations of future world " that lattice show, in " glamour front line science-glance back ", and do not mention that transform light energy becomes mechanical kinetic energy to be used for generating or directly uses 2006.

Three, the problem of the confidential solution of solar power and technological scheme

The problem of the confidential solution of solar power is: under the prerequisite of few loss thermal medium, the heat energy that the medium that solar thermal collector is heated stores converts mechanical kinetic energy to by the device of similar steam turbine, and the oneself's circulation that promotes thermal medium of a part of utilizing the mechanical kinetic energy produced to be finishing exchange heat, to make thermal medium flow to solar thermal collector to be repeated to finish heat-moving transfer process by heating once more, thereby mechanical kinetic energy is constantly exported in circulation.

Concrete technological scheme is as follows:

1, makes a relative isolated obturator with external environment.Top is the dish shape of flat-top, can be described as the moving switch room of heat, and the moving transducer of heat of similar steam turbine is installed by portion within it, and circular folding formula (" S " type) pipeline that is used for exchange heat; The effect of the moving switch room of heat be finish thermal power transfer become the exchange between gas-liquid phase thermal medium of mechanical kinetic energy and outside output kinetic energy, after-heat, gaseous state thermal medium through heat exchange and by dish shape shell to extraneous cooling fluidization in order to recycling.The bottom is round barrel shape, can be described as the storage medium chamber, and its diameter is less than the moving switch room of heat, is mainly used in to store the liquid heat medium medium that presets and the medium after the liquefaction in order to recycling, and the pipeline of fed sheet of a media is by storage medium chamber turnover obturator.Belt pulley and gear train assembly are installed on the shell of obturator, are made it to connect mutually, drive the Lever type pressure pump medium that storage medium is indoor and be pressed into cycle cooling plating drum with the hot kinetic energy output terminal of moving device.

2, will import the moving transducer of heat by the high pressure high temperature vapor (the supposition medium is a water) that the solar thermal collector heating produces from bottom to top through pipeline, high compressed steam is through the jetburner ejection of the moving transducer of heat, because of the recoil effect produces rotation function, simultaneously, heat is moved device and by belt pulley part kinetic energy is sent to gear train, drive the Lever type pressure pump hydraulic pressure is gone into circulating line, high-pressure water flow is moved the chamber and high-temperature vapor carries out exchange heat through heat, flows to solar thermal collector thereafter and is heated vaporization once more and finishes the moving conversion of heat again.Because volume can enlarge 1000 times behind the vaporizing liquid, must effective kinetic energy output.

3, carry the pipeline of thermal medium to handle, to reduce the heat loss of heat energy in course of conveying with thermal-protective material.

4, the effect of Lever type pressure pump is under the drive of gear, produces high pressure, is pressed into circulating line with the liquid medium of guaranteeing the storage medium chamber, finishes the cyclic process of thermal medium.

The heat energy that solar energy driven machine is transformed with solar energy is power; and can need not heat-storage medium, greatly reduce thermal medium loss and automatic cycle and utilize under the situation of thermal medium; improve efficiency of utilization by heat exchange; for in the desert, the arid area of lack of water and on building energy conservation, utilize solar energy to create condition; and can be as required; use independent the dispersion, but also the concentrating type scale is installed.The output kinetic energy of solar energy driven machine is mainly used in generating, directly uses for the user, also can be used for batteries to store energy or brine electrolysis production Hydrogen Energy; Also can be used as mechanical energy directly is applied.In the collection of solar energy, for economical with materials and produce high temperature, should adopt reflecting condensation formula solar thermal collector.The solar energy driven machine apparatus system is the integrated of current material and technology, its manufacture cost and technical requirements are far below photovoltaic cell, be easy to improve the solar energy utilization ratio by technological means, be easy to produce and popularization and application, and to improve the efficient of photovoltaic cell, except technical factor, also need to cross over the restriction on the physics, be extremely difficult the breakthrough.
