Abstract
The invention provides a general automatic condensation precision detection device for a solar parabolic concentrator, which is designed in a modular manner, can realize detection of concentrators with different focuses by only replacing the concentrators with different focuses and regulating a height position of a fixed receiver, is simple in operation and can rapidly, accurately and actually reflect a focusing precision of a concentrator to be detected. The invention belongs to the technical field of solar heat energy utilization. The detection device has the technical scheme as follows: the concentrator to be detected is fixed on a concentrator installation and fixation module, and a receiver is regulated and fixed in a corresponding focal line position. A positioning and walking mechanism is started according to a programmed procedure so that a light-emitting source walks in an S-shaped manner on an X-Y plane, the concentrator to be detected is subjected to grid point irradiation, the data analysis and processing is carried out according to a position signal of the receiver, and the condensation precision of the concentrator is calculated.
Description
Technical field
The present invention relates to a kind of sun power parabolic concentrator optically focused precision automatic detection system; The rectilinear light beam that this equipment utilization laser generator produces; Reflex on the receiver that is installed on the parabolic focal line through condenser; According to the reflected light signal distribution results that receiver receives, directly judge the optically focused precision of condenser through computational analysis.Belong to solar energy and utilize technical field.
Background technology
The key element that the sun power parabolic concentrator utilizes as groove type solar heat energy, its optically focused precision is most important, because sunshine is exactly to realize focusing on and accomplish the photo-thermal conversion by condenser.But condenser is in manufacturing process, and can there be error in its parabolic shape, is difficult to the parabolic shape that reaches desirable, influences the solar energy thermal conversion efficiency.At present, have only some general shape scanning survey equipment,, can not directly reflect the spotlight effect of condenser though can measure its geomery more exactly.Particularly at the initial stage of China's groove type solar heat energy utilization development, needing badly provides a kind of special checkout equipment, for optically focused checkout equipment and the method for setting up China's sun power parabolic concentrator standard are prepared.
?
Summary of the invention
The technical matters that the present invention will solve is for the sun power parabolic concentrator a kind of general optically focused precision automatic detection system to be provided.
The alleged problem of the present invention is solved by following technical scheme:
Sun power parabolic concentrator optically focused precision automatic detection system is made up of four module, and promptly light emitted device and location walking module, condenser install and fix module, condenser heliogram receiver module, programmed control and data processing module.The light emitted device is selected the instrument that can produce visible straight Shu Guang like laser pen etc. for use, is fixed on the travel mechanism of X-Y plane location, realizes the control of displacement accurately, and condenser is carried out trickle net point irradiation.It is to be used for fixing the primary steel structural member that supports condenser that condenser installs and fixes module, can be suitable for the condenser of different focal.Condenser heliogram receiver module is to be fixed on the focal line support of condenser to be detected by special heliogram receiver, only need adjust height dimension for the condenser of different focal and get final product.Programmed control and data processing module are made up of touch-screen, scrambler and self-compiling program, carry out data analysis according to the position signalling of receiver and handle, and calculate the optically focused precision of condenser.
The condenser that needs are detected is fixed on condenser and installs and fixes on the module, and with the receiver adjustment, be fixed on the corresponding focal line position.Open the location travel mechanism according to the program of finishing, make light emitting source on X-Y plane, carry out snakelike walking, condenser to be detected is carried out the net point irradiation, the position signalling according to receiver carries out the data analysis processing again, calculates the optically focused precision of condenser.
This checkout equipment adopts modular design; Only need to change the condenser of different focal, and adjust the fixedly height and position of receiver, just can realize the detection of different focal condenser; Simple to operate, can reflect the focusing accuracy of tested condenser fast, accurately, truly.
