Abstract
The invention discloses a shape surface error detection method for a lens unit of a solar-powered disc type light-gathering system. The method comprises the following steps that: a laser transmits electron beams onto the lens unit of the solar-powered disc type light-gathering system; the electron beams are reflected onto a receiving target through a surface lens of the lens unit to form a reflected image; video scanning equipment acquires the reflected image on the receiving target, and transmits to a computer; and the computer performs comparison operation on the reflected image from the video scanning equipment and a preset ideal image to obtain the shape surface error of the lens unit and further judge whether the shape surface error of the lens unit is up to a specification. The method has the beneficial effects that: the reflected image formed by transmitting the electron beams to the lens unit through the laser is compared with the preset ideal image, and a judgment on whether the shape surface error of the lens unit is in a designed range is made, so that a lens system of the solar-powered disc type light-gathering system is adjusted, and solar energy is better gathered through the solar-powered disc type light-gathering system.
Description
Technical field
The present invention relates to the solar light-heat power-generation technical field, more particularly, relate to a kind of sun power dish formula condenser system lens unit shape surface error detection method.
Background technology
The solar energy thermal-power-generating technology refers to the sunshine gathering is obtained high temperature, then by conventional heat engine or other generation technologies heat energy is changed into the technology of electric energy.The solar energy thermal-power-generating technology mainly contains tower type thermal generation, tank-type thermal power generation, the generating of dish formula heat.Wherein, dish formula system has following advantage: (1) distributes flexibly, and is little to site requirements, both can form distributed small-scale generating, also can form systematic large-scale and generate electricity by way of merging two or more grid systems.(2) dish formula system adopts Two axle drive, and the optically focused performance is good, throws the electrical efficiency height.Dish formula system optically focused can be heated to gas working medium more than 1000 ℃ than up to more than 2000, and is suitable with baroque tower system, is higher than slot type system (400-500 ℃) far away, and dish formula system is that solar energy thermal-power-generating is most effective at present.(3) simple in structure, the scientific research direction is clear and definite.The disc type solar energy electricity generation system mainly is comprised of condenser, heat dump and stirling generator, can be separately to these three sides and the research of tackling key problems.(4) cost is with the largest potentiality.Plant in the solar heat power generation system at first three, the cost potentiality of dish formula system are maximum.From technical standpoint, the critical process of solar energy thermal-power-generating comprises solar radiation is carried out high-density aggregation and thermal energy storage.The lens systems of sun power dish formula condenser system is that solar radiation is gathered energy accumulating device on the sun power receiving plane, play solar radiation and carry out the effect of high-density aggregation, therefore, the static foozle of the face shape on lens systems surface is one of the gordian technique of the lens systems of sun power dish formula condenser system.
Summary of the invention
The present invention is directed to the proposition of the lens unit shape surface error problem of above detection sun power butterfly condenser system, and develop a kind of sun power dish formula condenser system lens unit shape surface error detection method, detect the shape surface error of each sun power dish formula condenser system lens unit whether within designed scope.
A kind of sun power dish formula condenser system lens unit shape surface error detection method is characterized in that, may further comprise the steps:
S1, the eyeglass of condenser is carried out the unit cut apart, be divided into lens unit, laser instrument divergent bundle on the lens unit of sun power butterfly condenser system;
S2, electron beam reflex on the receiving target by the surperficial eyeglass of lens unit, make lens unit form reflected image at receiving target;
S3, videoscanning equipment gather the reflected image on the receiving target, and the reflected image that collects is emitted to computing machine;
The reflected image that S4, computing machine will come from videoscanning equipment compares computing with default ideal image, knows lens unit shape surface error size, and then whether judge the shape surface error of lens unit up to specification.
Implement sun power dish formula condenser system lens unit shape surface error detection method of the present invention, have following beneficial effect: by laser instrument to the lens unit divergent bundle, and form reflected image at receiving target, reflected image and the ideal image of presetting are compared computing, judge that the shape surface error of lens unit is whether within designed scope, thereby adjust the lens systems of sun power dish formula condenser system, make sun power butterfly condenser system better assemble sun power.
