Description
Affiliated technical field:
The present invention relates to a kind of solar panel tracking technique, particularly a kind of sunlight tracking system that can be used for automatically tracing sun by solar cell panel, this system can drive automatically tracing sun by solar cell panel light.
Background technology:
Solar energy is a kind of clean energy resource, inexhaustible, nexhaustible, can not cause environmental pollution yet, nowadays, no matter in coastal cities, still in inland city, solar product enters people's the visual field just more and more, solar street light, solar lawn lamp, solar energy garden lamp, solar corridor lamp, bus station's desk lamp, traffic lights or the like.But the solar energy receiving element of these solar products receives sunshine in the fixed-site mode mostly, because of can not whole day keeping vertical with sunshine, causes solar energy utilization ratio low.Therefore can the solar energy receiving element in use aim at the sun all the time, just becomes the problem of paying close attention to the most when people utilize solar energy.
In recent years, external in the photovoltaic matrix of some solar power stations, realized sunshine from motion tracking, domestic also have similar experimental rig, but these apparatus structure complexity, the cost height is difficult to use in small-sized home-use solar energy receiving equipments such as solar street light, solar lawn lamp.
Summary of the invention:
Bulky in order to overcome existing tracking means complicated in mechanical structure, and tracking means cost height, shortcomings such as energy consumption is big. the present invention is directed to the deficiency that prior art exists, prior art is improved, proposed that a kind of volume is little, simple and reliable for structure, cost is low, follow the tracks of the solar tracking device that energy consumption is little, wind loading rating is strong, it can drive solar panel and finish level and the vertically tracking of both direction.
The technical solution adopted for the present invention to solve the technical problems is: a motor, two spur gears, a worm screw and a worm gear have been installed in the good deceleration box of intensity.The circular hole that main shaft passes the worm gear center is fixed on the worm gear, and main shaft stretches out from deceleration box top, and is connected with the seat, center of solar panel with a connecting plate by a bearing pin.A bearing is fixed on the deceleration box bottom, one end of a length-adjustable support bar is fixed on the bearing, the other end is connected with an end of a length-adjustable connecting rod with a bearing pin by a back shaft, connecting rod can be done around back shaft and horizontally rotate and do vertical rotation around bearing pin, the other end of connecting rod is connected with the base of solar panel with a connecting plate by a tee T bearing pin, a brace summer, and connecting rod can be done around the tee T bearing pin and horizontally rotate and do vertical rotation around brace summer.
When motor rotates, driving worm screw by a motor shaft and two spur gears rotates, good mutually meshing of worm and wheel, the rotation of worm gear drives the main shaft rotation and drives solar panel by main shaft and horizontally rotates, the solar panel base horizontally rotate the rotation that has driven connecting rod, and the rotation by connecting rod, driven solar panel and finished around the vertical rotation that is fixed on the bearing pin on the seat, solar panel center.
When solar cell board plane and sunray depart from the upright position, motor powers up rotation by control system, transmission by spur gear, worm screw, worm gear, main shaft, connecting rod etc., finish level and the vertically tracking rotation of both direction, the solar cell board plane is returned to and the sunray upright position.At this moment, motor is cut off the power supply by control system.
When motor did not power up rotation, because of the one-way and the irreversibility of worm screw, worm-drive, solar panel can not move under wind-force and other external force effects.Therefore this device has good wind resistance.
The invention has the beneficial effects as follows, can finish the motion of two frees degree, and can realize good wind resistance by the one-way and the irreversibility of worm screw, worm-drive by a motor.The tracking energy consumption is little, cost is low, and is simple in structure, reliable.
