Description
Technical field
The present invention relates to a kind of solar tracking heat collection device for adjustable mirror, belong to technical field of solar utilization technique.
Background technology:
Current global energy situation is more and more severe; though the energy resource consumption of many industrialized countries tends towards stability; but developing country speeds up owing to process of industrialization; make the increase of energy resource consumption also accelerate; cause global energy consumption on average to be the trend of exponential increase; in the face of the potential collision hazard of fossil energy and the continuous deterioration of ecological environment, renewable resources such as development and use solar energy are important channel and the effective measures that realize the energy industry sustainable development.
The utilization of solar energy comprises the direct conversion of solar photoelectric, the direct utilization and the solar energy thermal-power-generating of solar heat, wherein the major technique of solar heat utilization is to solve the collection efficiency of solar energy and the manufacturing cost of equipment, current because the industrialization production of vacuum heat collection pipe, the solar water heater Industry Promotion of low-temperature water heating is used in obtaining, obtained bigger economic benefit and social benefit, but the utilization that obtains the solar collecting device of elevated temperature heat working medium also is in the elementary step.Current, the heat collection that obtains high-temperature medium in the world mainly contains three classes: the groove type line-focusing system, tower collecting system and dish formula collecting system, tower and dish formula also is in the experimental prototype stage, have only the groove type line-focusing thermal-arrest to produce the generating of steam pushing turbine and realized commercialization, 9 trough type solar power generation stations building up in the Southern California of U.S. LUZ company for example, what condenser mirror adopted is the glass silver of hot bending process, the reflection collecting efficiency is about 60%, total installation of generating capacity 354MW, current is worldwide largest, the solar electrical energy generation engineering of the groove type line-focusing system that commercialization is the most successful.
Groove type line-focusing thermal-arrest principle is to utilize parabolic reflector that sunlight is focused on the heat pipe, and hot working fluid in the heat pipe is heated to the condition of high temperature, the shortcoming of this thermal-arrest mode is the manufacture difficulty height of parabolic reflector, the accuracy of manufacture is difficult to guarantee, the hot bending process of speculum is complicated and yielding, manufacturing cost is very high, and along with long-play in adverse circumstances, the distortion of frame causes parabolic mirror also to deform, the focusing efficiency of sunshine is reduced, thereby solve the manufacture difficulty of the curved surface of slot light collection solar collector, the accuracy of manufacture, the long-term stability of focusing efficiency and manufacturing cost and focusing accuracy is the basic of decision slot type thermal-arrest generating commercialization popularization.
Summary of the invention:
The purpose of this invention is to provide a kind of make simple, focusing accuracy is high and adjustable, solar heat collection efficiency height and the low solar tracking heat collection device for adjustable mirror of cost.
For realizing above purpose, the present invention has adopted following scheme: speculum adopts the combination of many cover regulating reflection mirror units, each sheet speculum all can adopt a kind of simple mechanism to carry out the adjustment of reflection angle, the heat pipe of line focus solar heat gathering-device is fixed on the top of cylinder support, the regulating reflection mirror unit is installed on the cylinder support, the cross section of cylinder support can be an also curved section of broken line, and the single shaft auto-tracking sun device is installed on the cylinder support.This heat collector is that East and West direction is installed along the length direction of heat pipe, two-sided photovoltaic module detects the running of the relative position of sunshine and heat collector by comparison circuit control uniaxiality tracking device, make the cylinder support do the rotation of following the tracks of the sun in sun angle of site direction, the angle of the speculum by adjusting the regulating reflection mirror unit makes the sunshine that is radiated on the adjustable mirror to reflex on the heat pipe.By the heat pipe assembly that comprises joint, a reflection thermal-arrest unit is formed in many cover regulating reflection mirror units, cylinder support, tracking rotating shaft and support, if a plurality of such thermal-arrest units in series are East and West direction installs, and in sun angle of site direction under the situation of the motion tracking sun, just can make the working medium in the heat pipe obtain higher temperature, can be used for the heat utilization of high temperature or carry out the heat generating.
Support among the present invention that the cylinder support of regulating reflection mirror unit does not need high precision, the member of regulating reflection mirror unit all is cheap reliable parts, when first the installation, once focus on adjustment, after operation a period of time, treat again the angle of speculum once to be adjusted after all part distortion are stablized, so can remain high solar heat collection efficiency, the reflection collecting efficiency can reach more than 80%, so just overcome the manufacture difficulty of traditional groove type line-focusing device parabolic cylinder support, the hot bending cost height of parabolic minute surface, precision is difficult to guarantee and distortion in the future and reduce the problems such as collection efficiency of solar energy, thereby the present invention is easier to commercialization and applies.
