Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, and in particular to a self-adjusting photovoltaic bracket that follows a light source and its usage method. Background Technology

[0002] Solar energy is renewable, pollution-free, and available year-round, making it particularly prevalent in remote areas lacking power grids, such as deserts, islands, and mountainous regions. Currently, most photovoltaic panel supports are fixed-tilt, which, due to the cosine effect, cannot guarantee perpendicular sunlight, resulting in low solar energy utilization efficiency.

[0003] Chinese patent application CN202410463534.1 discloses a pull-rope type mobile photovoltaic system and a method for calculating the angle adjustment of photovoltaic panels. Compared with traditional photovoltaic panel brackets, this bracket adjusts the angle of the photovoltaic panels by shaking the pull rope, which can effectively match the angle of sunlight and maximize energy utilization. At the same time, it proposes a method for calculating the length of the pull rope and the rotation angle of the photovoltaic panel, which can be used to match the size according to the actual situation.

[0004] Product drawbacks: Due to the structural limitations of the back of the photovoltaic bracket, the angle adjustment range is limited when adjusting the photovoltaic panel angle by pulling the rope; at the same time, the structure requires the use of a hand crank when adjusting the angle, making the adjustment inefficient and unsuitable for large-scale application. Summary of the Invention

[0005] To address the problem of low energy utilization efficiency of photovoltaic panels due to the inconvenience of adjusting the angle of existing photovoltaic brackets, this invention provides a self-adjusting photovoltaic bracket that follows the light source and its usage method.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a self-adjusting photovoltaic bracket that follows the light source, including a photovoltaic panel that can rotate 360°, an anchor rod in the middle of the photovoltaic panel, and roller sets at both ends of the photovoltaic panel for adjusting the changing angle of the photovoltaic panel.

[0007] Furthermore, a ball joint is installed at the bottom center of the photovoltaic panel, and the ball joint is mounted on a ball joint support rod.

[0008] Furthermore, the ball joint support rod is mounted on the base plate of the support rod.

[0009] Furthermore, the ball joint is provided with a ball joint housing, which is fixed to the bottom of the photovoltaic panel.

[0010] Furthermore, anchor rods are provided on both sides of the bottom center of the photovoltaic panel.

[0011] Furthermore, the anchor rod is fixed to the middle of the photovoltaic panel by ropes and hooks.

[0012] Furthermore, the anchor rods are located on both sides of the ball joint.

[0013] Furthermore, the roller assembly includes two rollers mounted on roller support rods, with one end of the rope fixed to the bottom of the photovoltaic panel and the other end connected to the rollers.

[0014] Furthermore, the roller is mounted on the roller support rod via the roller shaft.

[0015] Furthermore, the ropes are secured to the bottom of the photovoltaic panel using hooks.

[0016] A method for using a self-adjusting photovoltaic bracket that follows a light source includes the following steps:

[0017] Step 1: Install the ball joint support rod;

[0018] Step 2: Secure the anchor rod and roller support rod;

[0019] Step 3: Connect the hook to the anchor rod with rope;

[0020] Step 4: Adjust the photovoltaic panel to face the sunrise and place it vertically;

[0021] Step 5: Connect the hook and the roller with a rope, and leave enough rope length to wrap around the roller;

[0022] Step Six: At sunrise, turn on the motor that drives the roller shaft and adjust the roller speed according to the sunshine duration to ensure that the photovoltaic panel moves to the sunlit direction at sunset.

[0023] Step 7: After sunset, reverse the motor to return the photovoltaic panel to the sunlit direction for sunrise the next day.

[0024] The beneficial effects of this invention are as follows: The use of a ball joint structure for angle adjustment ensures that the photovoltaic panel can rotate 360°; the use of anchor rods for bracket fixation ensures the stability of the bracket; the stepper motor controls the rotation speed of the rollers, automatically adjusting the changing angle of the photovoltaic panel to ensure that the adjustment cycle of the photovoltaic panel matches the daily sunshine cycle; and by changing the rotation speed of the stepper motor, the photovoltaic panel can swing at high frequency in heavy snow, preventing it from being covered by snow.

[0039] A self-adjusting photovoltaic bracket that follows the light source includes a photovoltaic panel 1 that can rotate 360°, an anchor rod 9 in the middle of the photovoltaic panel 1, and roller sets at both ends of the photovoltaic panel 1 for adjusting the angle of the photovoltaic panel 1.

[0040] A ball joint 7 is installed at the center of the bottom of the photovoltaic panel 1, and the ball joint 7 is mounted on a ball joint support rod 8. The ball joint support rod 8 is mounted on the support rod base plate 11. A ball joint housing 6 is provided outside the ball joint 7, and the ball joint housing 6 is fixed to the bottom of the photovoltaic panel 1.

[0041] Anchor rods 9 are provided on both sides of the bottom center of the photovoltaic panel 1. The anchor rods 9 are fixed to the middle of the photovoltaic panel 1 by ropes 10 and hooks 2. The anchor rods 9 are located on both sides of the ball joint 7.

[0042] The roller assembly includes two rollers 3, which are mounted on roller support rods 5. One end of a rope 10 is fixed to the bottom of the photovoltaic panel 1, and the other end is connected to the roller 3. The rollers 3 are mounted on the roller support rods 5 via roller shafts 4. The rope 10 is fixed to the bottom of the photovoltaic panel 1 via hooks 2.

[0043] A method for using a self-adjusting photovoltaic bracket that follows a light source includes the following steps:

[0044] Step 1: Install ball joint support rod 8;

[0045] Step 2: Fix the anchor rod 9 and the roller support rod 5;

[0046] Step 3: Connect the hook 2 to the anchor rod 9 using rope 10;

[0047] Step 4: Adjust photovoltaic panel 1 to face the sunrise and place it vertically;

[0048] Step 5: Connect the hook 2 and the roller 3 with rope 10, and leave enough rope 10 to wrap around the roller 3;

[0049] Step Six: At sunrise, turn on the motor that drives roller shaft 4, and adjust the speed of roller 3 according to the sunshine duration to ensure that photovoltaic panel 1 moves to the sunlit direction at sunset.

[0050] Step 7: After sunset, control the motor to reverse and restore photovoltaic panel 1 to the sun-facing direction for sunrise the next day.

[0051] The process of adjusting the bracket angle:

[0052] 1. Ensure that the movement trajectory of photovoltaic panel 1 matches the movement trajectory of the sun.

[0053] The ball joint 7 can rotate freely inside the ball joint housing 6. When the photovoltaic panel 1 is bound to the anchor rod 9 and the hook 2 on both sides, the ball joint 7's degree of freedom of movement is only the swinging left and right sides, which is exactly in line with the alternation of the sun's movement throughout the day.

[0054] 2. Ensure that photovoltaic panel 1 can swing left and right.

[0055] There are two sets of rollers on each of the front and rear sides of the photovoltaic panel 1. The rollers 3 are connected to the hook 2 by the rope 10. When the rollers 3 start to rotate, the rope 10 is tightened by the rollers 3, which causes the force on both sides of the photovoltaic panel 1 to be uneven, and the overall orientation of the photovoltaic panel 1 tilts towards the side with the force.

[0056] 3. Ensure the oscillation period of photovoltaic panel 1 is adjustable.

[0057] By controlling the rotation speed of the rollers 3 on both sides of the photovoltaic panel 1, the time it takes for the photovoltaic panel 1 to swing left and right can be equivalent to the duration of sunlight in a day.

[0058] 4. Angle adjustment process during heavy snow weather

[0059] By controlling the rollers 3 on both sides of the photovoltaic panel 1 to reciprocate at high frequency, the photovoltaic panel 1 can be oscillated left and right at high frequency, ensuring that snow does not cover the photovoltaic panel 1.

[0060] Method for adjusting the angle of photovoltaic panel 1:

[0061] The motion of photovoltaic panel 1 can be approximated as circular motion around the center of photovoltaic panel 1, according to the attached... Figure 8 As shown, the length of OA at this time can be approximated as the radius of the circular motion, while the arc length AB is the change in length of the rope 10 corresponding to the swing of the photovoltaic panel 1. According to our setting of the swing speed of the photovoltaic panel 1, we only need to ensure that the distance traversed by the rotational angular velocity ω of the roller 3 multiplied by the radius r of the roller 3 within the corresponding time t is the arc length AB.

[0062] This can be expressed as a formula:

[0063]

[0064] With attachment Figure 5-7 Taking the three postures as an example, the initial state of photovoltaic panel 1 each day should be a left-swinging posture facing the sun. At this time, the left roller 3 needs to be reversed to release rope 10, while the right roller 3 rotates clockwise to tighten rope 10, ensuring that photovoltaic panel 1 can slowly swing to the right. After photovoltaic panel 1 has followed the sun all day, it needs to be restored to the left-swinging posture in the evening. At this time, the above process is reversed, with the left roller 3 rotating clockwise to tighten and the right roller 3 rotating counterclockwise to release.

[0065] Considering that the sunshine duration t1 varies each day, while the arc length AB of the photovoltaic panel 1 and the radius r1 of the roller 3 are both constant, the rotational angular velocity ω of the roller 3 needs to be adjusted in real time according to the sunshine duration t1.

[0066] To improve the energy utilization efficiency of photovoltaic panel 1, an adjustable tilt photovoltaic panel 1 can be used to change the tilt angle of the solar panel, so that it faces the sun directly, thereby increasing the amount of solar radiation absorbed by photovoltaic panel 1 and achieving the purpose of increasing power generation.

[0067] The power generation efficiency of photovoltaic panel 1 is improved by adjusting its angle. A ball joint 7 on the back of photovoltaic panel 1 allows for 360° rotation without dead angles. Two anchor rods 9 on photovoltaic panel 1 are used, with two hooks 2 fixed to the sides of the ball joint housing 6 on the back of the panel. Ropes 10 connect the hooks 2 to the anchor rods 9 at the bottom, restricting the rotation and swaying of photovoltaic panel 1. The lengths of the ropes 10 at both ends can be adjusted according to the geographical location of photovoltaic panel 1 and its relationship to the sun, determining the left and right tilt angles of photovoltaic panel 1. During heavy snowfall, the rotational speed and frequency of the power source's direction changes are increased, increasing the swaying amplitude and frequency of photovoltaic panel 1 to prevent snow accumulation on the panel surface.

[0068] The present invention adopts a ball joint 7 structure, which facilitates the adjustment of the angle; anchor rods 9 are placed on both sides of the photovoltaic panel 1 and connected to the photovoltaic panel 1 by ropes 10 to ensure the stability of the photovoltaic panel 1; by adjusting the rotation speed of the roller 3, the oscillation period of the photovoltaic panel 1 can be ensured to conform to the daily sunshine cycle; by adjusting the rotation speed of the roller 3, the photovoltaic panel 1 can be prevented from being covered by heavy snow in heavy snow weather.
