Description

The solar automatic tracking device
Technical field
The utility model relates to a kind of solar automatic tracking device.
Background technology
The mankind directly utilize sun power that three big technical fields are arranged, i.e. photo-thermal conversion, opto-electronic conversion and photochemistry conversion in addition, also have energy storage technology.The product of sunlight heat switch technology is a lot, like water heater, boiler, exsiccator, heating and refrigeration, and greenhouse and solar energy housing, solar cooker and high temperature furnace, sea water desalinating unit, water pump, thermal power generation device and solar energy therapy utensil.
Sun power is the energy that a kind of low-density, intermittence, space distribution constantly change, and this just has higher requirement to the collection and the utilization of sun power, although work out a series of solar energy equipment such as solar water heater, solar dryer, solar cell or the like in succession; But the utilization of sun power also is nowhere near, and traces it to its cause, and mainly is that utilization factor is not high; With regard to present solar energy equipment, how to improve solar energy utilization rate to greatest extent, still be the research focus of Chinese scholars; Address this problem and should start with from two aspects, the one, the energy conversion rate of raising solar energy equipment, the 2nd, the receiving efficiency of raising sun power; The former belongs to field of energy conversion, is still waiting research, and the latter utilizes existing technology then can solve; Solar tracking system provides possibility for addressing this problem; No matter which kind of solar utilizing equipment, vertical if its heat collector can remain with sunshine, and collect the sunshine on more multi-direction; So, it just can collect more sun power in limited usable floor area.But the sun all is to move all the time, and if heat collector want is collected the sunshine on more multi-direction, and that just must follow the tracks of the sun; The professor of Architecture Department of Hong Kong University has studied the relation of sun light irradiation angle and sun power acceptance rate; Theoretical analysis shows: the tracking of the sun and non-tracking; The acceptance rate of energy differs 37.7%; The accurate sun of following the tracks of can make the receiving efficiency of receiver improve greatly, and then has improved the solar energy utilization ratio of solar energy equipment, has widened the field that utilizes of sun power.
The utility model content
The purpose of the utility model is exactly the influence that receives sun light irradiation angle for the conversion efficiency that solves solar panel; And a kind of solar automatic tracking device that provides; This device can rotate along with the sun; Make the sunlight direct projection on solar panel, make solar panel keep higher conversion efficiency.
The utility model solves the technical scheme that its technical matters adopted:
The solar automatic tracking device is characterized in that comprising: a base, base are provided with a rotating shaft one of vertically placing; The lower end of rotating shaft one is connected through gearing and motor one; The upper end of rotating shaft one is provided with a support, and support is provided with a rotating shaft two, and rotating shaft two is provided with a coaxial fluted disc; The top of fluted disc is connected with a solar panel; Bottom and a gearing mesh that is driven by motor two evenly are provided with four photoresistance on the periphery of described solar panel, two wherein relative photoresistance constitute a comparer; Contrast signal is passed to control device, and control described motor one or motor two by control device.
Described gearing can be selected gear drive, band transmission or chain transmission.
The mechanism structure of this device: motor one is fixed on the base, and the output shaft of motor one connects pinion wheel, pinion wheel and gear wheel engagement; Gear wheel is connected in the rotating shaft one, and rotating shaft one is installed in (rotating shaft one can be rotated with respect to base) on the base, and a support is installed in the rotating shaft one; Support can rotate with rotating shaft one, motor two is installed, the output shaft connection gear of motor two on the support; Gear and fluted disc engagement; Fluted disc is connected with rotating shaft two, and rotating shaft two is rack-mount, is connecting solar panel on the fluted disc.
Mechanism realizes the principle from motion tracking: system adopts photoresistance light intensity relative method; Design a kind of brand-new photoelectric conversion device; Well realized opto-electronic conversion; It can utilize the photoresistance relative method to realize the omnidirectional tracking to sun level, vertical direction, and just automatically reset evening, when skew takes place for the level of the sun or upright position; Must there be one to receive solar radiation in photoresistance R1, R2 or R3, four photoelectric tubes of R4 (another organizes control circuit), so just can have confirmed the direction of solar motion.
Control circuit has two groups of identical circuit, and photoelectric tube is directly to be connected with control circuit, when solar panels over against the solar time, R1, R2 are high resistance; Two point voltages equate that the voltage of output is identical, and the signal difference that control device is received is zero, do not rotate so control device is not controlled motor; If the sunlight run-off the straight makes Rl hit by sunlight and is low resistance, then the R2 current potential is higher than the R1 point; Signal is through amplifying and conversion, and then control device makes motor rotate and drags solar panels and rotates, and makes solar panels aim at the sun again; When R1, R2 transferred high resistance to again, the motor stall made R2 hit by sunlight during as if sunlight deflection and is low resistance; Then motor counter-rotating, though which kind of situation, always thereby the direction of the direction of motor movement and solar motion is consistent. reached the purpose of following the tracks of.Light weakens in weighing down to sun west, and the resistance of photoelectric tube R5 (level, vertical reset shared) raises, the BG5 conducting, and the motor counter-rotating, when getting back to original position, limit switch breaks off, the motor stall.When sunray departed from, control device sent control signal drive motor one and drives pinion rotation, and pinion wheel drives gear wheel and rotating shaft one is rotated; Control signal drive motor two driven gears simultaneously, the gear driven fluted disc rotates with solar panel, and the co-operation realization through motor one, motor two is to the tracking of solar azimuth and elevation angle.
The beneficial effect of the utility model be this device through photoresistance light intensity relative method, realize tracking by the co-operation of control device control motor one, motor two to solar azimuth and elevation angle; The control of photoresistance light intensity relative method is more accurate, and the circuit ratio is easier to realize.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings:
Fig. 1 is the front view of the utility model;
Fig. 2 is the side view of the utility model.
