Abstract

The invention provides a photocell array tracking device which belongs to the field of solar power application. Photocells for large-scale solar power generation are arranged in an array manner. In the prior art, the array is composed of a plurality of tracking devices which are respectively provided with two sets of transmission devices, thus a plurality of motors and gear reducers are needed, resulting in high cost. In the invention, two sets of transmission devices are adopted to drive the array, which comprises the following steps: a photocell frame (8) is fixed at both ends of a stub shaft (4) on a long shaft (3) to constitute a group and a plurality of groups constitute a row; beams (21) are adopted to fix a plurality of rows into the array; and flexible transmission parts (17) are adopted to sequentially sleeve transmission wheels (16) of the long shaft with driving wheels (10) at the end of a motor (9); flexible transmission parts (6) are adopted to sequentially sleeve delivery wheels (7) of a delivery shaft (18) with transmission wheels (5) of the stub shaft (4), thus driven wheels (15) on the delivery shaft (18) are coupled with driving wheels (14) at the end of a motor (13). In the device, two motors are adopted to drive the array and photocells of thousands of square meters track the sun, thus the generation cost is greatly reduced.

Description

Photocell square formation tracking means

Affiliated field

The invention belongs to especially solar energy tracking device of Application of Solar Energy field.

Background technology

The solar power generation of scale, photocell all demanding party's battle array are arranged, known tracking mode is that every table apparatus overlaps Mechanical ﹠ Electrical Transmissions with two, and a square formation is formed by some, and this must use a lot of platform motors and decelerator, and cost is too high.

Summary of the invention

The objective of the invention is provides a kind of easier tracking means to the photocell that square formation is arranged.

Its solution is: fix many minor axises on the major axis of fixing in the bearing of column upper end, at minor axis center fixed drive, minor axis two ends fixed frame constitutes row; Be fixed on the column with crossbeam, multiple row is constituted square formation; Fixed conveyor wheel on major axis, with flexible drive parts successively with drive and the driving wheel socket that is fixed on the slow speed motor termination on the column; Fixing transmission shaft in walking crosswise column top bearing is fixed on transmission shaft on the major axis by bearing with fixture; The fixed-site delivery wheel corresponding with major axis on transmission shaft used flexible drive parts again, with delivery wheel successively with major axis on the drive socket; At fixedly driven pulley and the driving wheel coupling that is fixed on the slow speed motor termination on the column on the transmission shaft.

With the tracking means of many crossbeams with a square formation of multiple row photocell framework formation, since highly low, more because being one puts in order, so wind resistance is good especially; Because only drive a square formation with two cover tumblers, the photocell of thousands of square meters is followed the tracks of the sun, thus can significantly reduce cost, thus reduce electricity price, improve systematic competitiveness.

Description of drawings

Accompanying drawing is the structural representation of photocell square formation tracking means.Dotted line is represented the part that do not paint among the figure.

Embodiment

Fixing major axis [3] in many root posts [1] upper ends bearings [2] utilizes bearing (not drawing among the figure) fix many minor axises [4] on major axis [3], at minor axis [4] center fixed drive [5], and two ends fixed frame [8], two is one group, many groups constitute one and are listed as; Be fixed on column [1] with many crossbeams [21] and upward multiple row constituted square formation; Go up fixed conveyor wheel [16] at major axis [3], and make them point-blank, with flexible drive parts [17] successively with drive [16] and be fixed on driving wheel [10] socket of slow speed motor [9] termination on the column [1]; Fixing transmission shaft [18] in column [11] upper end bearing [12] is fixed on major axis [3] termination by bearing [19] with transmission shaft [18] with fixture [20]; Fixing delivery wheel [7] on transmission shaft [18] position corresponding with major axis [3] center, with flexible drive parts [6] with delivery wheel [7] successively with drive [5] socket that is fixed on the major axis [3]; Going up fixedly at transmission shaft [18], driven pulley [15] is coupled with the driving wheel [14] that is fixed on slow speed motor [13] termination on the column [11].Under the driving of controller (not drawing among the figure), two motors rotate, and just drive the photocell that is fixed on the framework [8] from the motion tracking sun.

Slow speed motor noted earlier is meant that what motor and decelerator were assembled into one, this patent comprise that also motor and decelerator are splits, and at this moment driving wheel [10] and [14] are just on the output shaft of decelerator.

The described major axis [3] that is fixed on pillar [1] top of this patent is a hollow, and available channel-section steel, empty stomach steel, angle steel, band steel or steel pipe manufacturing as long as the centre of axle is empty, all belong to the protection range of this patent.

The position of flexible drive parts [6] is to pass from bearing [2] through the centre of major axis [3].

Driving member [6] can be made of steel wire rope, belt, chain, nylon rope with driving member [17], so long as soft driving member all drops on the protection range of this patent.

This programme further improves, and transmission shaft [18] and relevant transmission mechanism are arranged on the square formation middle part, and promptly the front and back of transmission shaft [18] all are provided with major axis [3] and form square formation, and motor [9] and motor [13] are arranged on the column at square formation center.

Delivery wheel [7] and drive [5] and driving wheel [10], driving wheel [14] driven pulley [15] is all made of nylon.

Delivery wheel [7] and drive [5] are made of engineering nutriment.
