Description

Technical Field

[0001] The present invention relates to the technical field of dual-axis tracking azimuth angle adjustment equipment, and in particular to a dual-axis tracking azimuth angle adjustment method and device. Background Art

[0002] As a renewable energy technology, solar power generation is one of the green power development energy projects that the country encourages most. However, the position of the sun changes every moment, so how to efficiently utilize sunlight is a core issue that must be solved. Since the position of the sun is constantly changing, the receiving surface must also be constantly oriented to the optimal position, so it is necessary to track the sun. At this stage, the most common tracking device is an electric push rod drive. After the motor is reduced by gears or worm gears, it drives a pair of lead screw nuts to convert the motor's rotational motion into linear motion. The motor uses forward and reverse rotation to complete the up and down movement of the push rod, thereby achieving azimuth angle adjustment.

[0003] The traditional dual-axis tracking azimuth angle adjustment device adopts several methods such as electric push rod drive, hydraulic push rod drive, and worm gear reducer. These traditional driving methods and traditional installation methods are high in cost, low in precision, and inconvenient in installation and maintenance. They are technical problems that need to be urgently solved in the prior art. Among them, the most important disadvantage of these traditional methods is that they need to purchase relatively expensive drivers and reducers, so it is difficult for traditional dual-axis tracking azimuth angle adjustment devices to achieve cost reduction and efficiency improvement in this regard. The azimuth angle adjustment device of the present invention adopts an innovative solution that combines a drive rope with a linear drive structure and uses an ordinary motor and reducer drive, which well achieves cost reduction and efficiency improvement in this regard, making the product more competitive in the market. Summary of the invention

[0004] The object of the present invention is to provide a method and device for adjusting the azimuth angle of dual-axis tracking to solve the problems raised in the above-mentioned background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a method and device for adjusting the azimuth angle of dual-axis tracking, comprising a driving wheel, a driving groove being provided on the surface of the driving wheel, a column being rotatably connected to the inner wall of the driving wheel, an upper transmission wheel being rotatably connected to the surface of the column, a transmission rope fixing piece being fixedly connected to the inner wall of the driving groove, a driving rope being rotatably connected to the inner wall of the driving groove, a lower surface of the driving rope being rotatably connected to the lower transmission wheel, and a linear driving mechanism being arranged at the end of the driving rope.

[0006] Furthermore, the surface of the driving rope is slidably connected to the surface of the lower transmission wheel, four columns are provided, and the four columns are symmetrically distributed with the driving wheel as the center. The surface of the driving rope is slidably connected to the surface of the upper transmission wheel, and the top of the column is fixedly connected to a limit transmission device.

[0007] Furthermore, the linear drive mechanism includes a motor, the output end of the motor is fixedly connected to a screw, the surface of the screw is threadedly connected to a screw movable plate, the inner wall of the screw movable plate is fixedly connected to round rod one, the end of the screw movable plate away from round rod one is fixedly connected to round rod two, the surface of the column is fixedly connected to an outer shell, the surface of the outer shell is fixedly connected to a fixed plate, the end of round rod one is fixedly connected to round rod connecting plate one, and the end of round rod one away from round rod connecting plate one is fixedly connected to round rod connecting plate two.

[0008] Furthermore, the end of the screw rod is rotatably connected to the inner wall of the shell, the motor fixed connection body is at the bottom of the shell, the end of the drive rope is fixedly connected to the surface of a round rod connecting plate, and the surface of the fixed plate is fixedly connected to the surface of the column.

[0009] Furthermore, the method for dual-axis tracking azimuth angle adjustment comprises the following steps: S1: When the dual-axis tracking azimuth angle needs to be adjusted during use, the linear drive mechanism is started, and the motor of the linear drive mechanism drives the screw to rotate; S2: The screw rod rotates to drive the round rod connecting plate to move up and down, and the driving rope is fixedly connected to the round rod connecting plate. When the round rod connecting plate moves up and down, the driving rope is driven to reciprocate; S3: The driving rope drives the driving wheel to rotate, and the driving wheel drives the main beam to rotate, thereby finally driving the angle adjustment of the dual-axis tracking azimuth; S4: When the drive rope is driven into place, it will be sensed by the limit actuator, and then it will be limited by the encoder inside the motor.

[0010] The present invention has the following beneficial effects: The invention discloses a method and device for adjusting the azimuth angle of dual-axis tracking, comprising a driving wheel, an upper transmission wheel, a transmission rope fixing part, a linear driving structure, a driving rope, a lower transmission wheel, and a column. The rotation of a motor in the linear driving structure drives a screw rod to rotate, and the rotation of the screw rod causes a round rod to move up and down. A driving rope is installed on a round rod connecting plate, and the driving rope bypasses the transmission wheel to reach the driving wheel. When the round rod moves up and down, the driving rope drives the driving wheel to rotate to adjust the azimuth angle. The azimuth angle adjustment device of the invention adopts an innovative solution combining a driving rope with a linear driving structure, which greatly improves the installation method of a traditional driving system, while ensuring the accuracy of the driving system, and facilitating the sealing protection and later maintenance of an external push rod. Compared with a traditional dual-axis tracking azimuth angle adjustment device that adopts an electric push rod drive, a hydraulic push rod drive, and a worm gear reducer, the driving cost of a dual-axis tracking bracket is greatly reduced, and the accuracy and reliability are improved.

[0011] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
