Abstract

It is an object of the invention to provide a kind of " adaptive full-automatic tracking technology ", solve by what tracker change in location caused by typhoon or the change of environment earth's surface was brought largely manually adjusts.For heat collector tracking system of the large area using direct radiant light, maintenance cost and cost of labor are greatly reduced.Such as solar light-heat power-generation system, direct radiant light must be used to realize the maximum utilization of light, and general solar-thermal generating system has ten hundreds of trackers, these trackers must be firmly fixed on ground very much, movement is avoided, the direct radiant light of the daily sun is impinged upon on heat collector.This exacting terms is a kind of hope to unpredictable environment.As we know that the wind in environment is to allow these trackers to move at any time, the change of ground surface is even more unpredictable.So needing manually to be adjusted at any time.This is a huge engineering.The maintenance cost and cost of labor of investor is added, the utilization of solar energy is affected.If using the invention, will thoroughly solve this problem.

Description

Direct solar radiation light twin shaft automatic condensing heat collector

1. technical field：

Direct solar radiation light twin shaft automatic condensing heat collector, be related to direct solar radiation light from motion tracking, be it is complete from The dynamic full-automatic adaptive tracking system for realizing direct solar radiation light.

2. background technology

The development of micro-electromechanical technology, makes original mechanical structure be realized with electric frame mode by integrated circuit.Direct spoke Penetrate optical sensor, angular speed and obliquity sensor etc. to be integrated in 8mmX8mm even more small chips, make these original The function that could be only realized with very big volume is implemented as reality with small integrated circuit now.So that these Technology is applied to be achieved from the system of motion tracking and direct solar radiation light heat collector.And direct radiation can be made full use of Light realizes various applications.Such as light is converted into electricity, light and is converted into heat.Realize that inexhaustible solar energy resources maximizes profit With.Contributed for society.

3. the technical problem to be solved

In existing sun light tracking device, simply realize sunshine track motion tracking, and directly radiant light with Track needs extremely complex system to realize, particularly can not realize adaptive full-automatic regulation.Once tracker is installed After good, tracker cannot be allowed excessive displacement occur.If it is well known that directly radiant light offset by the angle of very little, light It can not just shine directly on the object to be radiated, than the heat collector in such system.So as to which sunshine can not be realized most Big efficiency is utilized.System solves the problem this problem.It has used multiple sensors and electronic gyroscope to constitute a control bit Shifting system.Needing simultaneously at direct radiant light heat collector, placing at the 8 of an optical sensor such as Fig. 1 to receive direct radiation Light, after judging whether position is accurate, feeds back to the position of system single-chip microcomputer de-regulation tracker, if position shifts, just Send an adjustment signal to be proofreaded to tracker single-chip microcomputer, allow tracker to remain the shape for being in and directly radiating with sunlight State.Realize the maximum utilization of light.Form the tracking system of a full-automatic regulation.Different from traditional tracking system, it is necessary to The initial position of tracker is fixed, present concentrator position is positioned by several tons of heavy pillars.And at any time Immovable, such as typhoon or geographical change shift tracker, just have to proofread each tracker again.This is right It is a huge engineering for tens of thousands of individual even hundreds of thousands trackers.The method of the invention to biaxial tracker in itself Position does not have too high requirement.As long as the signal of optical sensor is judged, it is necessary to be adjusted automatically when adjustment The position that direct radiant light shines, it is possible to realize that direct radiant light does not change the incidence angle to heat collector.So as to solve it is existing with Track device, which must fix good position, could accurately track direct radiant light this problem.

4. the content of the invention：

1. it is an object of the invention to provide a kind of " automatic adjusument receives the fully automatic system of direct solar radiation light ".Solution Certainly tracker is due to environmental change or non-artificial displacement, and direct solar radiation light can not be irradiated on required heat collector And ineffective or needs manually readjust incident angle.The present apparatus adds a directly radiation light sensing on tracker 8 in device such as Fig. 1, after tracker produces displacement, it sends deviation model and calibrated automatically to single-chip microcomputer, makes the object moment Keep the direct radiation regimes with sunlight.Fig. 1 is the structure chart of direct solar radiation light twin shaft automatic condensing heat collector, and Fig. 2 is Concentrator position layout drawing in direct solar radiation light twin shaft automatic condensing heat collector, often arranging has 4 concentrating collectors.If It is not that direct radiant light is impinged upon above, then the energy of light can be greatly reduced and reduce, and sunshine is unable to reach highest Efficiency.

2. it is an object of the invention to provide a kind of " adaptive full-automatic tracking technology ", solve due to typhoon or environment earth's surface What tracker change in location caused by change was brought largely manually adjusts.To large area using direct radiant light heat collector with For track system, maintenance cost and cost of labor are greatly reduced.Such as solar light-heat power-generation system, it is necessary to use directly radiation Light could realize the maximum utilization of light, and general solar-thermal generating system has ten hundreds of trackers, and these trackers are necessary It is firmly fixed on ground very much, it is to avoid mobile, daily sunlight is directly radiated on speculum or heat collector.It is this Exacting terms is a kind of hope to unpredictable environment.As we know that the typhoon in environment is to allow these to track at any time Device is moved, and the change of ground surface is even more unpredictable.So needing manually to be adjusted at any time.This is a huge engineering. The maintenance cost and cost of labor of investor is added, the utilization of solar energy is affected.If, will be thorough using the invention Solve this problem.

3. the present invention is once examined using the direct light radiating sensor on tracker, each hour to direct radiant light Survey, so as to realize full-automatic adaptive Gaussian filtering.It was found that self-alignment position after skew.If 8 in Fig. 1 are exactly direct radiation Optical sensor.Adjustment time can freely be set.

4. brief description of the drawings

Fig. 1 is the overall structure figure of direct solar radiation light twin shaft automatic condensing heat collector.1 is heat collector, and it has been It will be utilized after to the multiple amplification to light after the liquid heating in heat collector；2 be fixed heat collector shelf；3 be daylight with Track ring-shaped guide rail；4 be the annular master driver of daylight tracking, by single-chip microcomputer control driving stepper motor operating；5 be daylight tracking ring Shape driven pulley, its material is to use a kind of endurance rubber, when rotated with wear-resisting water-proof function, it is to avoid use pulley, axle Holding etc. needs to lubricate and maintenance materials, can so use for a long time, reduces maintenance cost；6 be the angular driver of daylight；7 It is the angular drive link mechanism of daylight；8 be direct light radiating sensor, judges the irradiating angle of light to adjust the angle of heat collector Degree.During usual illumination daily, the initial position of heat collector is adjusted to one angle signal of single-chip microcomputer.Heat collector is set to be in reception The position of direct radiant light；9 be tracker and ground concrete base rack；10 be geometrical clamp.
