Description

A kind of array Dual-spindle linked hurricane resistant sun tracker
Technical field
The present invention relates to field of solar thermal power generation, specifically a kind of array Dual-spindle linked Hurricane resistant sun tracker.
Background technology
In existing solar energy tracking device, biaxial movement can be realized, can realize that array links again It is less, can the hilly and mountainous land that suitably can just rise and fall again of hurricane resistant install few, because It is relatively difficult that too many aspect control is taken into account for such array Dual-spindle linked tracks of device.
Describe in number of patent application CN201520544695.X patent and a kind of easily to realize Array Dual-spindle linked tracks of device, the device controls every group of photovoltaic in array by turbine and worm The Bearings tracking of system, this is relatively good technology in current azimuth tracking device, still It is this that the technology for realizing Bearings tracking is rotated by the occlusion of turbine worm, if for twin shaft connection Dynamic using effect will have a greatly reduced quality, because worm gear and worm screw are used to during single shaft linkage be all the time tightly Occlusion, that is because the two ends of oblique single shaft are fixed, if for the oblique single shaft of Dual-spindle linked Rear portion must just be fallen at daily noon sooner or later raise, due to oblique single shaft rear portion track the sun Elevation angle needs the yardstick raised larger, is also exactly that semi-circle gear is arranged on into photovoltaic panel peace Frame up bearing of the frame foremost on preceding pedestal or distant, when the rear portion of oblique single shaft is in morning When late two periods are elevated one meter or so, turbine and worm screw are changed into loose from snapping tight against Occlusion, the photovoltaic panel installation frame of 1.8 meters or 2.6 meters 5 meters or longer of length of width is only It will hold very much running into high wind photovoltaic panel installation frame by the occlusion fixation of several teeth foremost Easily swung by blast and cause gear or worm gear broken teeth phenomenon, be also exactly hundred meters of arrays by some Power transmission shaft connects into an installation, then is fixed on through countless bearings and bearing on preceding pedestal, array In countless light pay plate framework be it is ratcheting and rotate by the worm gear on semi-circle gear and power transmission shaft, Countless light pay plate framework be also by the worm gear on semi-circle gear and power transmission shaft is ratcheting and wind resistance, 50 groups of every group ten squares of photovoltaic board components in hundred meters of arrays are attacked suddenly when high wind to put down for 500 altogether Aspect product is in be swung to a direction wound to hit power transmission shaft by blast simultaneously, now whole transmission system The bonding strength of the joint gap of middle power transmission shaft and power transmission shaft, power transmission shaft and bearing, bearing exists Bearing close in left and right gap, joint gap of the turbine on power transmission shaft, turbine controlled half Teeth of Knucle-gear etc., each link is likely to occur failure, is chained up without several Each module lifting, due to many load weights of module, all very likely holds in power transmission shaft driving array Caused to damage distortion by incessantly blast or even deformed, these all give the accuracy of manufacture of photovoltaic module The requirement of challenge is proposed with installation quality.
It can reduce and invest into for the photovoltaic plant with certain installed capacity in a word This, reduce driving quantity, be easily installed, design simple and durable it is easy to maintenance, wind resistance and Desertification performance etc. is also all epochmaking integrated survey factor.NORTHWEST CHINA area light application time is long But desert, hilly and mountainous land hurricane are more, typhoon is frequent again for the southeastern coastal areas, photovoltaic panel peace Frame up frame can by all directions pressure.This anti-wind control to photovoltaic panel installation frame is carried The requirement of challenge is gone out.Other destruction of the dust storm to photovoltaic generation tracking transmission system is not allowed more Ignore, worm gear drive is not suitable for sandy region, snaps tight against worm and gear top and fill after the grains of sand Being compressed in again in the middle of worm and gear directly can wrack transmission system and cause greatly damage Lose.
In summary, current field of photovoltaic power generation, which lacks one kind, can control a row or multi-row battle array High parallactic angle linkage energy controlling party parallactic angle linkage again simultaneously in row subsystem, it is anti-with extremely strong wind resistance Husky ability adapts to desert, coastal, hilly and mountainous land large area laying again, is easily installed, if Count the convenient photovoltaic module array tracking device of simple-to-maintain.
The content of the invention
It is low that the purpose of the present invention provides a kind of cost for deficiencies of the prior art It is honest and clean, design is simple, be easily installed, a kind of array Dual-spindle linked hurricane resistant easy to maintenance too Positive tracks of device.
The present invention is realized by next mode:A kind of array Dual-spindle linked hurricane resistant sun Tracks of device, including motor, driving axial winding drum, photovoltaic panel installation frame, photovoltaic face Plate installation frame support base, fixed pulley, azimuth steel wire rope tensioning system, high-order angle steel silk Rope tensioning system,
