Description
Technical field
The present invention relates to a kind of sun power parabolic concentrator focal spot proving installation, this device makes full use of the rectilinear light beam that semiconductor laser produces, and by paraboloidal mirror body reflection measurement optically focused focal spot, its device is simple, easy to implement the method, be widely used in various parabolic concentrator devices.Belong to technical field of solar utilization technique.
Background technology
Setting up solar-energy light collector is the basic fundamental means that realize that sun power utilizes, and particularly in sun power paraboloid trough type solar concentrating generation device, mainly realizes focusing on and finish the photo-thermal conversion by the parabolic concentrator device.Parabolic focusing belongs to line focus, also belongs to mirror image simultaneously and focuses on, and requires the beam condensing unit imaging clear, and the mirror image focal spot becomes an optically focused straight line, can assemble luminous energy to greatest extent, only in this way could guarantee the photo-thermal conversion efficiency maximization.But, owing in mirror body processing and fabricating, installation, truss fabrication and thermal-collecting tube installation process, all can have error, finally can cause optically focused focal spot off-design index, can't guarantee the photo-thermal conversion efficiency maximum.The method of test paraboloid trough type solar beam condensing unit is mainly by photographic equipment such as camera at present, by meniscus camera lens observation thermal-collecting tube position, though method is easy, but can only detect mirror position through the thermal-collecting tube of beam condensing unit reflection, and can not detect the effective width and the focal line position of mirror image focal spot, particularly develop the initial stage of trough type solar power generation in China, a kind of easy proving installation and the method for providing is provided badly, both can detect and debug, and progressively accumulate experience simultaneously and prepare for the parabolic concentrator examination criteria of setting up China field erected beam condensing unit.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of simple and practical optically focused focal spot proving installation for sun power parabolic concentrator device.
The present invention is solved by following technical scheme:
Sun power parabolic concentrator focal spot proving installation is made up of visible light generating laser, laser testing receiving target, fixed support, it is characterized in that: described visible light generating laser is made up of semiconductor LD laser module, focusing optically focused camera lens, power circuit etc., directly restraint the point focusing transmitter as the similar laser that can produce visible wavelength such as red, green such as laser pen, laser level, wherein preferred laser level also claims laser leveler.Described laser testing receiving target is test paper, focussing glass and the translucent plastic plate that has scale, perhaps adopts laser receivers such as photoelectricity laser silicon target, laser raster target, high sensitivity laser pickoff.Described fixed support is the metal support that visible light generating laser and laser testing receiving target are installed, and this support comprises vertical support frame and horizontal stand, has slidably groove and fastener respectively.The visible light generating laser is installed on the vertical support frame, and the laser testing receiving target is installed on the horizontal stand.
Method of testing is: the laser testing receiving target is installed on the horizontal stand, be positioned at parabolic concentrator device optically focused focal spot place, laser testing receiving target central point should be paraboloid focusing device central horizontal extended line and laser testing receiving target center joint, and can move horizontally on extended line; The visible light generating laser is installed on the vertical support frame, and vertical support frame becomes 90 degree vertical angles with paraboloid focusing device central horizontal extended line, and can be moved up and down to condenser body curved surface upper and lower side by condenser body center.Visible light generating laser launch window is towards the condenser body, laser beam becomes horizontality with focalizer center extended line, the irradiation condenser reflexes to the laser testing receiving target, after focusing, guarantee the laser facula minimum, after preliminary work finishes, vertical moving visible light generating laser and the pointwise recording laser hot spot facula position on the test receiving target, move horizontally the laser testing receiving target then, record hot spot centre distance, through debugging repeatedly and measuring, the minimum place of hot spot is best optically focused focal spot and focal spot width.
This device special feature is rectilinearity and the meticulous characteristic of focus that has made full use of the visible light laser beam, and device is simple, and is easy to implement the method, and test and adjustment also can be carried out simultaneously.This device can also be realized operation and record automatically through improving, particularly adopt laser receivers such as photoelectricity laser silicon target, laser raster target, high sensitivity laser pickoff also can directly to be connected, in vertical movement of visible light generating laser or the tangential movement of laser testing receiving target, realize detection of dynamic with computing machine.
