Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a light-tracking distributed photovoltaic module. Background Art

[0002] Photovoltaic power generation is a clean and renewable energy generation method. Its working principle is to use the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The basic fixing method of distributed photovoltaic power generation components is stable, the overall weight is light, and the cost is low.

[0003] The position, orientation and inclination of existing photovoltaic panels are relatively fixed. Since the position of the sun changes dynamically with time and season, fixed photovoltaic panels cannot adjust their orientation and inclination in real time, resulting in a significant reduction in the efficiency of light energy capture. This is especially true during the twilight period or in high-latitude areas, when the solar incident angle deviates from the optimal receiving angle of the photovoltaic panel, which seriously restricts the energy conversion efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a trackable distributed photovoltaic module to solve the problem raised in the above background technology that the position orientation and inclination angle of the existing photovoltaic panels are relatively fixed, resulting in a significant reduction in light energy capture efficiency and seriously restricting the energy conversion efficiency.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a trackable distributed photovoltaic assembly: comprising a support frame, an adjusting plate rotatably connected to the surface of the support frame, a one-way self-locking cylinder rotatably connected to the surface of the support frame, a piston rod of the one-way self-locking cylinder rotatably connected to the bottom of the adjusting plate, the bottom of the adjusting plate is fixedly connected to a servo motor, a worm is fixedly connected to the output shaft of the servo motor, a rotating rod is rotatably connected to the surface of the adjusting plate, the bottom of the adjusting plate is fixedly connected to a worm gear, the top of the adjusting plate is fixedly connected to a facing plate, a telescopic rod is fixedly connected to the surface of the facing plate, the telescopic end of the telescopic rod is fixedly connected to the photovoltaic panel body, a two-way self-locking cylinder is fixedly connected to the surface of the facing plate, the piston end of the two-way self-locking cylinder is fixedly connected to a moving block, the surface of the moving block is rotatably connected to a support rod, and the end of the support rod away from the moving block is rotatably connected to the bottom of the photovoltaic panel body.

[0006] Preferably, the adjustment plate and the photovoltaic panel body are parallel to each other, and the one-way self-locking cylinder pushes the adjustment plate to rotate on the surface of the support frame through the piston rod, and the adjustment plate drives the photovoltaic panel body to rotate synchronously.

[0007] Preferably, the orientation plate rotates on the surface of the adjustment plate via a rotating rod, and the orientation plate drives the photovoltaic panel body to rotate synchronously on the surface of the adjustment plate via a telescopic rod.

[0008] Preferably, the worm and the worm wheel are meshed with each other, the servo motor drives the worm to rotate via the output shaft, and the worm drives the rotating rod to rotate on the surface of the adjustment plate via the worm wheel.

[0009] Preferably, the rotating rod is located in the center of the adjustment plate, the facing plate is in the shape of an elongated plate and is smaller in width than the adjustment plate, and the width of the photovoltaic panel body is also smaller than the adjustment plate.

[0010] Preferably, the moving block is provided with two groups, the piston rod of the bidirectional self-locking cylinder is provided with two groups, and the bidirectional self-locking cylinder pushes the moving block to slide and rise on the surface facing the plate through the two groups of piston rods, and the moving block is overall in an "L" shape.

[0011] Preferably, the photovoltaic panel body is lifted and lowered on the facing plate by the telescopic end of the telescopic rod, and the telescopic rod is provided with two groups.

The adjustment plate drives the photovoltaic panel body to rotate synchronously through the facing plate and the telescopic rod, thereby changing the angle of the photovoltaic panel body on the support frame. The worm is then driven to rotate by the output shaft of the servo motor. The worm drives the rotating rod to rotate through the worm gear. The rotating rod drives the facing plate to rotate on the surface of the adjustment plate. The facing plate drives the photovoltaic panel body to rotate through the telescopic rod, thereby changing the direction of the photovoltaic panel body. By changing its own angle and direction, the photovoltaic panel body can always align with the direction of sunlight, ensuring the optimal angle of receiving light source, thereby improving energy conversion efficiency.

[0014] 2. This photovoltaic module uses two sets of piston rods of a bidirectional self-locking cylinder to push two sets of moving blocks to move in opposite directions on the surface of the facing plate. During the movement, the two sets of moving blocks drive the photovoltaic panel body to rise and fall on the facing plate, thereby changing the distance between the photovoltaic panel body and the adjustment plate. By changing the distance between the photovoltaic panel body and the adjustment plate, the photovoltaic panel body is prevented from colliding with the support frame during the process of changing the direction, thereby ensuring the stability of the photovoltaic panel body in adjusting the direction.

[0021] See also Figure 1-5 , an embodiment provided by the present invention:

[0022] A trackable distributed photovoltaic assembly: comprising a support frame 1, an adjustment plate 2 is rotatably connected to the surface of the support frame 1, a one-way self-locking cylinder 21 is rotatably connected to the surface of the support frame 1, a piston rod of the one-way self-locking cylinder 21 is rotatably connected to the bottom of the adjustment plate 2, a servo motor 26 is fixedly connected to the bottom of the adjustment plate 2, a worm 22 is fixedly connected to the output shaft of the servo motor 26, a rotating rod 23 is rotatably connected to the surface of the adjustment plate 2, a worm gear 24 is fixedly connected to the bottom of the adjustment plate 2, a facing plate 25 is fixedly connected to the top of the adjustment plate 2, a telescopic rod 3 is fixedly connected to the surface of the facing plate 25, a telescopic end of the telescopic rod 3 is fixedly connected to the photovoltaic panel body 11, and a worm 24 is fixedly connected to the surface of the facing plate 25. It is connected to a two-way self-locking cylinder 31, and the piston end of the two-way self-locking cylinder 31 is fixedly connected to a moving block 32. A support rod 33 is rotatably connected to the surface of the moving block 32. The end of the support rod 33 away from the moving block 32 is rotatably connected to the bottom of the photovoltaic panel body 11. The photovoltaic panel body 11 has a built-in optical module, and the optical module inside the photovoltaic panel body 11 inputs the light-tracking electrical signal into the one-way self-locking cylinder 21, the servo motor 26 and the control system inside the two-way self-locking cylinder 31, so that the photovoltaic panel body 11 can adjust the angle and direction on the support frame 1, so that the photovoltaic panel body 11 is always aligned with the direction of sunlight, ensuring the best angle for receiving the light source, thereby improving the energy conversion efficiency.

[0023] Furthermore, the adjustment plate 2 and the photovoltaic panel body 11 are parallel to each other, and the adjustment plate 2 and the photovoltaic panel body 11 always remain parallel. The one-way self-locking cylinder 21 pushes the adjustment plate 2 to rotate on the surface of the support frame 1 through the piston rod, and the adjustment plate 2 drives the photovoltaic panel body 11 to rotate synchronously, thereby changing the inclination angle of the photovoltaic panel body 11 on the support frame 1, and ensuring stable support for the inclination angle of the photovoltaic panel body 11 after the photovoltaic panel body 11 is tilted.

[0024] Furthermore, the facing plate 25 rotates on the surface of the adjustment plate 2 through the rotating rod 23, and the facing plate 25 drives the photovoltaic panel body 11 to rotate synchronously on the surface of the adjustment plate 2 through the telescopic rod 3. The photovoltaic panel body 11 changes its orientation on the support frame 1 through rotation, so that it can move upward in the direction of the sun.

[0025] Furthermore, the worm 22 and the worm wheel 24 are meshed with each other, and the servo motor 26 drives the worm 22 to rotate through the output shaft. The worm 22 drives the rotating rod 23 to rotate on the surface of the adjustment plate 2 through the worm wheel 24. The servo motor 26 has a built-in self-locking mechanism, which can limit the position of the worm 22 after rotation. The worm 22 limits the angle of the rotating rod 23 on the adjustment plate 2 through the worm wheel 24, thereby ensuring the orientation of the orientation plate 25 on the adjustment plate 2.

[0026] Furthermore, the rotating rod 23 is located at the center of the adjustment plate 2, and the facing plate 25 is in the shape of a long plate and has a width smaller than the adjustment plate 2. The rotating rod 23 drives the facing plate 25 to rotate at the center of the adjustment plate 2, ensuring that the facing plate 25 has sufficient rotation space. The width of the photovoltaic panel body 11 is also smaller than the adjustment plate 2, and the width of the photovoltaic panel body 11 is greater than the facing plate 25, ensuring the receiving area of the photovoltaic panel body 11 on the adjustment plate 2.

[0027] Furthermore, two groups of moving blocks 32 are provided, and two groups of piston rods of the two-way self-locking cylinder 31 are provided, and the two-way self-locking cylinder 31 pushes the moving block 32 to slide and rise and fall on the surface of the facing plate 25 through the two groups of piston rods. The moving block 32 is generally "L"-shaped, and the moving directions of the two groups of moving blocks 32 are opposite. After the movement is completed, it is restricted by the piston scraper of the two-way self-locking cylinder 31, and the position of the moving block 32 on the facing plate 25 is relatively stable.

[0028] Furthermore, the photovoltaic panel body 11 is raised and lowered on the facing plate 25 through the telescopic end of the telescopic rod 3. Two groups of telescopic rods 3 are provided. The moving block 32 pushes the photovoltaic panel body 11 to rise and fall on the facing plate 25 through the support rod 33 during the sliding process. The support rod 33 pushes the photovoltaic panel body 11 to rise and fall by rotating on the surface of the moving block 32, thereby changing the distance between the photovoltaic panel body 11 and the adjustment plate 2. By changing the distance between the photovoltaic panel body 11 and the adjustment plate 2, the photovoltaic panel body 11 is avoided from colliding with the support frame 1 during the process of changing the direction, thereby ensuring the stability of the photovoltaic panel body 11 in adjusting the direction.

[0029] Working principle: The piston rod of the adjusting plate 2 drives the adjusting plate 2 to rotate on the surface of the support frame 1, and the adjusting plate 2 drives the photovoltaic panel body 11 to rotate synchronously through the facing plate 25 and the telescopic rod 3, thereby changing the angle of the photovoltaic panel body 11 on the support frame 1, and then the output shaft of the servo motor 26 drives the worm 22 to rotate, and the worm 22 drives the rotating rod 23 to rotate through the worm gear 24, and the rotating rod 23 drives the facing plate 25 to rotate on the surface of the adjusting plate 2, and the facing plate 25 drives the photovoltaic panel body 11 to rotate through the telescopic rod 3, thereby changing the orientation of the photovoltaic panel body 11. By changing its own angle and orientation, the photovoltaic panel body 11 can always be aligned with the direction of sunlight, ensuring the best angle for receiving the light source, thereby improving the energy conversion efficiency.

[0030] The photovoltaic panel body 11 is raised and lowered on the surface of the facing plate 25 by the telescopic rod 3, and the two groups of piston rods of the two-way self-locking cylinder 31 push the two groups of moving blocks 32 to move in opposite directions on the surface of the facing plate 25. During the movement, the two groups of moving blocks 32 drive the photovoltaic panel body 11 to rise and fall on the facing plate 25, thereby changing the distance between the photovoltaic panel body 11 and the adjustment plate 2. By changing the distance between the photovoltaic panel body 11 and the adjustment plate 2, the photovoltaic panel body 11 is avoided from colliding with the support frame 1 during the process of changing its direction, thereby ensuring the stability of the photovoltaic panel body 11 in adjusting its direction.
