Description

Solar Intermittent Tracking Mechanical System

Technical field:

The utility model relates to a solar battery panel tracking technology, in particular to a mechanical transmission system that can be used in a solar battery panel automatic tracking system. The mechanical transmission system can form a solar battery panel automatic tracking together with a sunlight automatic tracking motor control system system.

Background technique:

Solar energy utilization is the development direction of clean energy utilization for human beings in the future, and various solar energy application products continue to emerge. However, in real life, most of the solar receiving elements receive sunlight in a fixed position, resulting in a low utilization rate of solar energy. To this end, various tracking methods have been studied,

There are two types of existing daylighting devices that track the sun: one is a tracking device that calculates the trajectory of the daylighting and lighting device according to the laws of the earth's orbit around the sun; the other is to detect the position of the sun relative to the ground in real time and control the tracking of the angle of the sun by the daylighting device device. Both types of tracking devices have disadvantages such as complex mechanical structure, high cost of tracking devices, inaccurate positioning, and poor wind resistance.

Invention content:

In order to overcome the disadvantages of the existing tracking device, such as complex mechanical structure, high cost of tracking device, inaccurate positioning, and poor wind resistance, the present invention aims at the shortcomings of the existing technology, improves the existing technology, and proposes a structure Simple and reliable solar tracking device with strong wind resistance, it can be driven by a motor to complete the horizontal and vertical rotation of the solar panel.

The technical solution adopted by the present invention to solve the technical problem is: a motor, two spur gears, a worm, and a worm wheel are installed in a strong casing. The center of the worm gear is connected with a main shaft, and the main shaft extends out of the casing and is connected with the center of the solar panel through a rotating shaft. A circular tube concentric with the main shaft is fixed outside the box, the lower end of the circular tube is fixed to the box body, and the upper end is cut into two symmetrical arcs. A circular ring is set on the main shaft, two cylinders are symmetrically fixed on the circular ring and the two cylinders smoothly connect with the arc of the upper end of the circular pipe. The symmetrical positions on both sides of the lower end of the solar panel are respectively connected to the two poles through a rotating shaft, and the other ends of the two poles are respectively connected to the ring through a rotating shaft. The spindle slides up and down. When the motor rotates, the two spur gears drive the worm to rotate and the worm to drive the worm wheel to rotate. The worm wheel drives the main shaft and the solar panel through the main shaft to complete the horizontal rotation. At the same time, the rotation of the main shaft also drives the ring and drives the two cylinders to move along the arc of the upper end of the circular tube through the ring, so that the ring slides up and down along the main shaft. The ring slides up and down along the main shaft to drive the pole, and through the pole, the solar panel is driven to rotate vertically along the center of the solar panel.

When the plane of the solar panel deviates from the vertical position of the sun's rays, the motor is energized by the control system to rotate, and through the transmission of spur gears, worms, worm gears, main shafts, rings, circular tubes, etc., the horizontal and vertical directions are completed. Rotate to restore the plane of the solar panel to a position perpendicular to the sun's rays. At this point, the motor is powered off by the control system.

When the motor rotates without power, due to the unidirectional and irreversible nature of the worm and worm gear transmission, the solar panel will not move under the action of wind and other external forces. Therefore, the device has good wind resistance.

The beneficial effect of the utility model is that the movement of two degrees of freedom can be completed by one motor,

And the unidirectional and irreversible properties of worm and worm gear drive can realize good wind resistance performance. The cost is low, the structure is simple and reliable.
