Abstract

A photovoltaic power generation tracker belongs to a solar energy utilization device. The double-shaft tracking for photovoltaic power generation needs more than 40% of electric energy. The known double-shaft tracking is supported by a single column, has poor wind resistance and is easy to blow down by strong wind especially when being installed on a high building. The utility model provides a tracker with good wind resistance, which is characterized in that a plurality of columns are supported and run synchronously, a photovoltaic frame [7] is fixed on two sides of a rotating shaft [3] through a rotating shaft [6], two photovoltaic frames form one, a plurality of photovoltaic frames form one column, the rotating shaft [3] is fixed on a supporting column [1] through a bearing [2], and a motor [14] drives a driving wheel [15] to drive the rotating shaft [3] to drive a row of photovoltaic modules to rotationally track the sun in east and west directions; the motor [13] drives the driving wheel [12] to drive the rotating shaft [6] to rotate through the flexible transmission part [11], so that one row of components rotate to track the sun on the elevation angle, and double-shaft tracking is realized. The investment is saved by using a male shaft for transmission and synchronous operation; the multi-column support has the advantages of gravity center support and good wind resistance, is more suitable for roof installation, and fully utilizes the solar energy of the roof.

Description

The photovoltaic generation tracker
Technical field
The utility model belongs to helioplant.
Background technology
Photovoltaic generation adopts double-axis tracking, get 35~40% electric energy more.Known solar biaxial tracker is to adopt only post to support.This mode area is little, the cost height of unit square rice, and area is big, just supports highly, and wind-force load greatly, especially is installed on the high building and is blown down by strong wind easily.
Summary of the invention
It is low that the purpose of this utility model provides a kind of height, the photovoltaic generation tracker that wind resistance is good.
Fixed rotating shaft [3] in the bearing [2] on many pillars [1] top; Utilization is fixed on the rotating shaft [6] in the rotating shaft [3], and the both sides that two photovoltaic frameworks [7] are fixed on rotating shaft [3] are formed one, is provided with many in the same old way and forms row; Utilizing flexible drive parts [11] to pass the drive [10] that will be fixed in the rotating shaft [6] from bearing [2] is socketed on the driving wheel [12] successively; Driving wheel [12] and motor [13] coupling that is fixed in the rotating shaft [3]; Drive [15] in the rotating shaft [3] is coupled with the motor [14] that is fixed on the pillar [1].
The employing multicolumn supports, and public through-drive, many are rotated synchronously, save material, reduced cost; The height centre of gravity is low, wind resistance good.
Description of drawings
Accompanying drawing 1 is a photovoltaic generation tracker schematic diagram.
Accompanying drawing 2 is to utilize tube material to make rotating shaft [3], the cutaway view of every tracker center.
Accompanying drawing 3 is partial schematic diagrams of making rotating shaft [3] of 2 band steels.
Accompanying drawing 4 is partial schematic diagrams of making rotating shaft [3] of 1 band steel.
Embodiment
Below in conjunction with accompanying drawing 1.2 an explanations embodiment of the present utility model.
Make the pillar [1] that many roots and tops have bearing [2] earlier, pillar can make as the ⊥ shape among the figure, also can make A shape; Otch on steel pipe [4], steel pipe is that garden shape also can be square, notch can be split up and down, at notch two side perforating rigid bearings [5] in order to fixed rotating shaft [6], steel pipe is fixed in the bearing [2] of pillar [1], the fixing photovoltaic framework [7] at bearing [6] two ends, and with connector [8], it is one of one composition that two frame fixation are linked, and forms one for many and is listed as; Photovoltaic module [9] is installed on framework, with flexible drive parts [11] will be fixed on already in the middle of the rotating shaft [6] drive [10] successively with driving wheel [12] socket that is fixed on rotating shaft [3] termination, driving wheel and casual speed motor [13] coupling that is fixed on the rotating shaft [3]; In casual speed motor [14] coupling that is provided with in the rotating shaft [3] on drive [15] and the anchor post [1], tracker south analogy is to (but also east-west direction) is set, under the driving of controller [17], motor [14] drives tracker and follows the tracks of the sun in the East and West direction rotation, and motor [13] drives the assembly of tracker previous column and follow the tracks of the sun on elevation angle.
Also need to go up the top that reaches rotating shaft [3] lid is set, in order to avoid rainwater immerses at notch [4].
Utilize tube material to make rotating shaft [3], flexible drive parts is passed from pipe be protected.
Further improvement of the utility model is seen Fig. 3, is to utilize two band steels [16] (comprise on an empty stomach band steel) to make rotating shaft [3] to be fixed in the bearing [2] on the pillar, and drive [4] and driving wheel [12] are fixed between two band steels.Utilize rotating shaft [6] that two photovoltaic frameworks [7] are fixed on band steel [16] both sides.
Utilize two band steels to do the big or small unrestricted of rotating shaft drive.
A step more of the present utility model improves and sees that Fig. 4 only makes rotating shaft [3] with a band steel [16] (comprising band steel on an empty stomach), be fixed on band steel [16] in the bearing [2] by the fixing photovoltaic framework [7] of rotating shaft [6], driving wheel [12] is fixed on the band steel [16], and drive [4] is fixed on the limit of photovoltaic framework [7].
More simple with band steel making rotating shaft [a 3] structure.
The tracker that the utility model provides is two and forms one, forms row for many, can also multiple row form square formation, is fit to large-scale solar energy power generating.Adopt public axle and many of flexible transmissions even multiple row run-in synchronism to follow the tracks of the sun, can significantly reduce investment, increase the benefit.Its center of gravity is low, and a face is big, wind resistance good, can be installed in ground Anywhere, and use in the place that roof preferably wind-force is bigger, makes full use of the solar energy on roof, plane.
