The tracking of the elevation angle in transmeridional Bearings tracking and north-south can be realized in the utility model by solar energy device following the sun, all the time just to solar illumination angle, thus the object improving solar energy utilization ratio can be reached to reach heat collector; Therefore knuckle section first demand fulfillment can carry out freely rotating of East and West direction and north-south.After improving, sun-following system cost design is as described in Figure 4 cheap, reliability is high, structure is simple; Mechanical steering gear structurally will accomplish compact conformation, rationally distributed.
This structure has very large rotation space in East and West direction and north-south, and structure is simple, and consumptive material is less, is relatively applicable to small-sized solar energy tracking electricity generation system.As figure, this mechanical steering gear basic composition mainly contains: base, lower floor's platform, upper platform, drive motors, deceleration device, cell panel fixed frame etc.
In the utility model, during enforcement, claimed structure is compact, and the motor volume therefore will selected can not be too large, and due to the restriction of structure, the power of motor and moment of torsion also can not be very large, directly driving mechanical steering mechanism can not do tracking sun's motion.Therefore suitable reducing gear to be selected to improve moment of torsion, steering mechanism is run well.In order to meet whole system compact conformation, requirement that volume is little, the decelerator can selected in this mechanical steering gear has following three kinds: turbine and worm decelerator, harmonic speed reducer and planetary reduction gear.
These three kinds of decelerators feature is separately as follows:
(1) main feature of worm type of reduction gearing has reverse self-locking function, can have larger speed reducing ratio, power shaft and output shaft not on the same axis, also not at grade.But general volume is comparatively large, and transmission efficiency is not high.
(2) harmonic drive of harmonic speed reducer is that motion and power are transmitted in the elastic deformation that utilizes flexible member controlled, and volume not quite, precision is very high, but shortcoming is flexbile gear restricted lifetime, not shock-resistant, and rigidity is poor compared with metalwork.Input speed can not be too high.
(3) its advantage of planetary reduction gear is that structure comparison is compact, and backhaul gap is little, precision is higher, and service life is very long, and it is very large that specified output torque can do.But price is slightly expensive.
Native system due to start-stop relatively frequent, impact comparatively large, be therefore not suitable for selecting harmonic speed reducer.Although planetary reduction gear precision is higher, expensive, the design original intention of this solar photovoltaic generation system can not be met.Therefore, in this double-shaft tracking mechanism, it is comparatively suitable for choosing turbine and worm decelerator.
The utility model requires can tracking position of sun more accurately, therefore requires that drive motors can accurately the angular displacement that transform electrical signals is on motor shaft.Native system chosen steps motor is as drive motors.The stepper motor that the design selects is 85BYGH350A.
The AT89C51 type single-chip microcomputer that single-chip microcomputer subassembly selection atmel corp in this control produces.AT89C15 is a kind of low-power consumption, high performance 8 single-chip microcomputers, and its adopts CMOS technology and high-density nonvolatile memory (NURAM) technology, and pin and instruction system all compatible with MCS 1.AT89C51 is that a kind of function is strong, flexibility is high and the single-chip microcomputer of reasonable price, can well meet the designing requirement of native system.
Native system designing requirement can carry out record to the time, and monolithic function reads the instant moment of program setting, and a timing chip therefore will be selected to provide extraction and the record of time for system.In this tracking system, what select is 8563 timing chips.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
