Description
Technical field
The invention belongs to the telescope technical field, be specifically related to a kind of radio telescope.
Background technology
Existing radio telescope comprises principal reflection mirror, and this principal reflection mirror is the antenna of paraboloid structure, and at the focus place of principal reflection mirror feed is installed, and the reflector focus of principal reflection mirror drops on the signal acquisition point of this feed.Utilize the parabola of principal reflection mirror to collect, catch radio radiation signal from remote celestial body, after the radio radiation signal is reflected to feed point, send to signal processing mechanism by feed, processing mechanism identifies the different characteristic of remote celestial body according to different radio radiation signal messages.The reflecting surface that is limited by principal reflection mirror can't infinitely increase, and therefore, tends to set up several radio telescopes, by each independently radio telescope carry out joint observation, can improve observation effect greatly.
Because feed is arranged in the reflector focus place of principal reflection mirror, and principal reflection mirror tends to sunlight also reflexed to and converges on the feed, thereby causes the feed temperature too high, damages feed.Therefore, prior art is to carry out diffuse reflection to handle on the reflecting surface of principal reflection mirror, and its structure mainly contains two kinds.
One, metal substrate layer is set, and applies one deck diffuse reflection lacquer, paint the plating transparent protective film in diffuse reflection again at the reflecting surface of metal substrate.
Two, the non-metal base flaggy is set, at the concave surface plating rete of non-metal base flaggy, the reflecting surface at metallic diaphragm applies one deck diffuse reflection lacquer again, paints the plating transparent protective film in diffuse reflection at last.
Though such structure has been protected feed, also lost part radio radiation signal.
The disc type solar energy heat generating system utilizes parabolic reflector with low-density solar energy collecting to a focus, its parabolic reflector just need be handled very smoothly, so that sunlight is fully converged to produces higher temperature on the heating device of Stirling engine, drive the Stirling engine running with heat energy, and then drive generator for electricity generation.A plurality of independently disc type solar energy heat generating systems can be formed a huge solar energy thermal-power-generating power station.
The shortcoming of prior art is: though the radio telescope array has similar agent structure with disc type solar energy heat generating system array, but mutual operation principle is different, therefore, prior art can not installed Stirling engine and generator on radio telescope, radio telescope can only carry out the radio radiation signal processing, and does not possess electricity generate function.
As a kind of generation mode of zero CO2 emission efficiently, disc type solar energy heat generating initial investment cost is higher.As the radio telescope that is used for scientific observation purely, invest huge and without any economically repayment, thereby its manufacturing depend on government's grant and patronage among the people, by the huge single radio telescope forming array of the quantity dream that is the astronomer always.
Summary of the invention
The invention provides a kind of radio telescope that carries out solar energy thermal-power-generating, by its array of forming, the collection, the processing capacity that had both possessed the radio radiation signal of radio telescope, the function that possesses the generating of disc type solar energy heat again, carry out solar energy thermal-power-generating daytime, carry out astronomical observation night, the equipment that integrates as two kinds of functions, construction cost can be saved greatly, the common development in generation of electricity by new energy and two fields of astronomical device fabrication can be promoted.
