Abstract

The utility model relates to a photovoltaic power generation tracker, which belongs to solar energy utilizing devices. The photovoltaic power generation used dual spindle tracking produce 40% electrical energy more. A known dual spindle tracker is supported with a single prop, the wind resistance performance is bad, and the dual spindle tracker is easily blown down by wind when the dual spindle tracker is installed on a high building. The utility model provides a tracker with good wind resistance performance. The tracker is characterized in that the tracker is supported by a plurality of props to operate synchronously, photovoltaic frames [7] are fixed on two sides of a rotary shaft [3] through a rotary shaft [6], two components are combined into one machine, a plurality of machines are combined into one array, the rotary shaft [3] is fixed on a prop [1] through a bearing [2], a motor [14] drives a driving wheel [15], which enables the rotary shaft [3] to drive an array of photovoltaic components to rotate southwards and westwards to tract the sun, a motor [13] drives an action wheel [12] to rotate the rotary shaft [6] through a flexible driving component [11], which enables an array of components to rotate on a height angle to track the sun, and dual spindle tracking is realized. Public shaft driving and synchronous operation save investment, the tractor is supported by a plurality of props, the centre of gravity is low, the wind resistance performance is good, the tracker is more suitable for being installed on the top of the building, and the solar energy on roof is fully utilized.

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.
