Abstract

The utility model relates to a novel solar cell panel steering mechanism apparatus. A dual-shaft automatic tracking system capable of automatically tracking the irradiation angle of the sunlight is utilized to improve the photoelectric conversion rate of the solar cell. According to apparatus, a single-chip microcomputer is used as a core; and a timing chip and a stepping motor are utilized to drive the dual-shaft tracking system. Therefore, a solar cell panel can be perpendicular to the incident light of the sun all the time, thereby improving the absorption efficiency of the solar energy.

Description

Novel solar battery plate steering mechanism device

Affiliated technical field

The utility model relates to solar panel, and especially a kind of solar panel steering mechanism is provided with.

Background technology

In order to improve solar energy utilization rate, present stage has had multiple tracking means both at home and abroad, and these tracking means have improved solar energy utilization rate really to a certain extent, but make a general survey of these products, also have the following disadvantages:

1. incident ray can not be parallel with the energy conversion primary optical axis partly of solar facilities all the time, and the effect that receives sun power is unsatisfactory.For example: the uniaxiality tracking device.

2. tracking accuracy is not enough, need regularly proofread and correct.For example: the clock type sun tracker.

3. have cumulative errors, and self can not eliminate.For example: the program control sun tracker.

4. do not have enough work spaces, can not finish automatically the sun is travelled to and fro between the tracking of moving between the tropic of north and south, ratio of precision is lower.For example: simple and easy fluid pressure type tracker.

5. can not automatically reset, it is excessive to satisfy day and night change track demand or tracking afterwards.For example: the formula sun tracker is put in control.

The utility model content

In order to solve the low excessively problem of solar energy utilization ratio, it is a kind of by solar collecting device that the utility model provides; Steering mechanism; Control section; Energy storage device; The a kind of of inverter formation is core with the single-chip microcomputer, and utilizes timing chip and step motor drive double-axis tracking system, makes solar panel all the time perpendicular to solar incident ray, realizes the bi-directional tracking to the sun, thereby improves the absorption efficiency of sun power.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of light-electric conversion ratio that can improve solar cell from the double-shaft auto-tracking system of motion tracking solar light irradiation angle that utilizes design.This system is to be core with the single-chip microcomputer, and utilizes timing chip and step motor drive double-axis tracking system, makes solar panel all the time perpendicular to solar incident ray, thereby improves the absorption efficiency of sun power.

The beneficial effects of the utility model are, make the solar attachment can be all the time over against the sun, thereby have realized absorption efficiency is improved in the tracking and the location of the sun.And make economic, simple in structure, dependable performance, be convenient to installation and maintenance.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the basic comprising of tracker

Embodiment

Among Fig. 1 the overall framework of whole tracker: when sunray, control section is started working, the timing chip can be monitored in real time and effectively read the time, determine the position angle of the sun, steering mechanism follows the tracks of the real time position of the sun, aim at the sun up to solar collecting device, through solar collecting device solar energy is converted into available electrical energy, the manufacturing purpose of energy storage device native system is that sun power is gathered, and the inverter native system that is used can be absorbed and transformed solar energy, and the electric energy of its generation stored, the alternating current by inverter produces just can be widely used in common AC electric appliance.

Tracker is judged, is compared and extract the time by low-power consumption, high performance AT89C51 type single-chip microcomputer among Fig. 2, making solar panel carry out corresponding angle according to different time control step motors again changes, the 8563 timing chips of wherein selecting for use that include I2C bus interface function and have an extremely low power dissipation carry out automatic computing time, and the step motor drive chip with the A3759 stepping motor drive integrated circuit connects single-chip microcomputer and stepper motor simultaneously.

Composite stepper motor 85BYGH350A is converted into corresponding angular on the motor shaft as drive motor with pulse electrical signal among Fig. 3, motor rotates an angle and drives NMRV04O turbine and worm reducer casing casing, swing arm rotation, thereby battery board bracket is rotated, finish the tracking of the elevation angle in tracking of transmeridional position angle and north-south, make solar panel reach the purpose that improves solar energy utilization ratio thereby reach all the time over against solar illumination angle.

The time data of timing chip reads in single-chip microcomputer for two mouthfuls by P1.0, P1.1 among Fig. 4, and single-chip microcomputer is controlled solar panel all the time over against the sun to the step motor drive chip transmission of control signals of control east-west direction and North and South direction respectively by P0.1～P0.4 and P2.0～P2.4 after treatment.
