Description

Technical Field

[0001] This utility model belongs to the field of aerospace technology, specifically, it relates to a solar panel with adaptive angle adjustment. Background Technology

[0002] Solar panels are core energy supply components for the operation of spacecraft such as artificial satellites and space stations in orbit. Their power generation efficiency and reliability are directly related to the lifespan of the spacecraft and the success or failure of the mission. Currently, traditional solar panels generally adopt sun-oriented technology, which uses light sensors (such as sun sensors) to detect the sun's position and a drive mechanism to control the rotation of the panel so that its surface is as perpendicular as possible to the sunlight, thereby maximizing the efficiency of light energy collection.

[0003] However, existing technologies have the following obvious limitations: Single-dimensional optimization problem: Most existing adaptive systems focus only on the single dimension of "angle adjustment." While they can effectively track the sun's azimuth and elevation angles, they fail to comprehensively consider the combined effects of changes in the spacecraft's distance from the sun as it orbits in an elliptical orbit. When the spacecraft approaches the sun (such as near perihelion), solar irradiance increases dramatically, generating more electricity but also causing a significant rise in the temperature of the photovoltaic panels. Excessive operating temperature not only reduces the conversion efficiency of photovoltaic materials (negative temperature coefficient) but also poses a risk of overloading the power management system or even causing permanent damage. Conversely, at aphelion, irradiance decreases, and as much energy as possible needs to be collected; existing systems lack the ability to self-manage such power fluctuations.

[0004] Insufficient flexibility and reliability of mechanical structure: In terms of angle adjustment mechanism, traditional hinge or shaft structure may cause problems such as transmission mechanism interference or connecting cable entanglement when adjusting within a large angle range. In addition, if the connection between the drive component and the fixed component cannot adapt to the relative position change caused by the angle change, it may generate additional stress, affecting the smoothness of the mechanism's movement and long service life. To address the aforementioned issues, this application proposes an adaptive angle-adjustable solar panel. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an adaptive angle-adjustable solar panel to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adaptive angle-adjustable solar panel includes a simulated satellite. Mounting rollers are movably connected to both sides of the simulated satellite. Mounting frames are fixedly installed on the sides of the two mounting rollers that are far apart from each other. Multiple photovoltaic panels are installed on the top of the mounting frames. A controller is installed inside the simulated satellite, and a four-quadrant sensor is installed on the outside of the simulated satellite. An angle rotation mechanism includes a fixed cylinder, which is fixedly installed on one side of the simulated satellite, and an installation roller is movably installed on the inner wall of the fixed cylinder; An adaptive photovoltaic connection mechanism includes a drive rod that is slidably mounted on the bottom of a mounting frame. A wiring rod is fixedly mounted on the bottom of the mounting frame. One end of the wiring rod is slidably connected to a telescopic rod. The telescopic rod is fixedly connected to the drive rod, and the telescopic rod and the drive rod are respectively electrically connected to the corresponding photovoltaic panels.

[0007] Preferably, the angle rotation mechanism further includes a motor, which is fixedly mounted on the bottom of the mounting frame. A screw is fixedly mounted on the output shaft of the motor, and a sleeve is threaded onto the screw, which is fixedly connected to the fixed cylinder.

[0008] The motor's output shaft drives the screw to rotate. The screw is connected to the sleeve via a thread, which allows the distance between the motor and the fixed cylinder to be adjusted.

[0009] Preferably, a positioning ring is rotatably connected to the outer side of the fixed cylinder, and the positioning ring is fixedly connected to the sleeve.

[0010] The rotatable connection between the positioning ring and the fixed cylinder allows the mounting bracket to maintain its connection with the fixed cylinder through the sleeve when the angle changes.

[0011] Preferably, the outer side of the mounting roller is provided with an arc-shaped groove, and a slider is fixedly installed on the inner wall of the fixed cylinder, with the slider slidably connected to the arc-shaped groove.

[0012] The movable installation roller is connected to the slider through an arc-shaped groove, allowing it to rotate and change angle on its own, which in turn drives the photovoltaic panel to change angle.

[0013] Preferably, the adaptive photovoltaic connection mechanism further includes a drive cylinder, which is fixedly installed at the bottom of the mounting frame. The end of the drive cylinder away from the simulated satellite is open, and a piston block is slidably connected to the inner wall of the drive cylinder. A top rod is fixedly installed on one side of the piston block and is fixedly connected to the drive rod.

[0014] The drive cylinder contains air and is located at the end where the piston block and the drive cylinder are closed. By changing the volume of air inside the drive cylinder, the piston block is driven to move back and forth, which in turn drives the push rod and the drive rod to move.

[0015] Preferably, both sides of the mounting bracket are slidably connected to limit blocks, and both limit blocks are fixedly connected to the drive rod.

[0016] The drive rod can be limited by the sliding connection between the limit block and the mounting bracket.

[0017] In summary, the technical effects and advantages of this utility model are as follows: 1. Temperature serves as a bridge connecting the mechanical and electrical systems. When changes in the distance between the satellite and the sun cause changes in the ambient temperature, the system not only adjusts the angle of the motor to pursue optimal sunlight, but also automatically changes the number of photovoltaic panels connected to the circuit based on the principle of thermal expansion and contraction, achieving a coordinated and intelligent response between the mechanical and electrical systems.

[0018] 2. The sliding connection between the arc-shaped groove and the slider allows the moving installation roller and the fixed cylinder to rotate at their own angle, thereby driving the photovoltaic panel to change angle. The motor is driven by a four-quadrant sensor and a controller. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An adaptive angle-adjustable solar panel includes a simulated satellite 1, with mounting rollers 2 movably connected to both sides of the simulated satellite 1. Mounting frames 3 are fixedly installed on the sides of the two mounting rollers 2 that are far apart from each other. Multiple photovoltaic panels 4 are installed on the top of the mounting frames 3. The simulated satellite 1 is equipped with a controller, and a four-quadrant sensor is provided on the outside of the simulated satellite 1. The angle rotation mechanism 5 includes a fixed cylinder 51, which is fixedly installed on one side of the simulated satellite 1, and the mounting roller 2 is movably installed on the inner wall of the fixed cylinder 51. The adaptive photovoltaic connection mechanism 6 includes a drive rod 61, which is slidably mounted on the bottom of the mounting frame 3. A wiring rod 62 is fixedly mounted on the bottom of the mounting frame 3. One end of the wiring rod 62 is slidably connected to a telescopic rod 63. The telescopic rod 63 is fixedly connected to the drive rod 61, and the telescopic rod 63 and the drive rod 61 are respectively electrically connected to the corresponding photovoltaic panels 4.

[0023] Reference Figure 1 and Figure 4 The angle rotation mechanism 5 also includes a motor 55, which is fixedly installed at the bottom of the mounting bracket 3. A screw 56 is fixedly installed on the output shaft of the motor 55. A sleeve 57 is threaded onto the screw 56 and is fixedly connected to the fixed cylinder 51. A positioning ring 52 is rotatably connected to the outside of the fixed cylinder 51 and is fixedly connected to the sleeve 57. The output shaft of the motor 55 drives the screw 56 to rotate. The screw 56 is threadedly connected to the sleeve 57, thereby adjusting the distance between the motor 55 and the fixed cylinder 51. The rotational connection between the positioning ring 52 and the fixed cylinder 51 ensures that the mounting bracket 3 remains connected to the fixed cylinder 51 through the sleeve 57 when the angle changes.

[0024] Reference Figure 4 An arc-shaped groove 54 is provided on the outer side of the installation roller 2, and a slider 53 is fixedly installed on the inner wall of the fixed cylinder 51. The slider 53 is slidably connected to the arc-shaped groove 54. The moving installation roller 2 can rotate and change its angle by itself through the sliding connection between the arc-shaped groove 54 and the slider 53, thereby driving the photovoltaic panel 4 to change its angle.

[0025] Reference Figure 2 The adaptive photovoltaic connection mechanism 6 also includes a drive cylinder 65, which is fixedly installed at the bottom of the mounting frame 3. The end of the drive cylinder 65 away from the simulated satellite 1 is open, and a piston block 66 is slidably connected to the inner wall of the drive cylinder 65. A top rod 67 is fixedly installed on one side of the piston block 66 and is fixedly connected to the drive rod 61. Limiting blocks 64 are slidably connected to both sides of the mounting frame 3. Both limiting blocks 64 are fixedly connected to the drive rod 61. The drive cylinder 65 stores air and is located at the end where the piston block 66 and the drive cylinder 65 are closed. By changing the volume of air in the drive cylinder 65, the piston block 66 is driven to move back and forth, which in turn drives the top rod 67 and the drive rod 61 to move. Through the sliding connection between the limiting blocks 64 and the mounting frame 3, the drive rod 61 can be limited.

[0026] Working principle: During operation, the light source is monitored by a four-quadrant sensor, and the motor 55 is rotated by the controller to ensure that the photovoltaic panel 4 is directly exposed to sunlight. The output shaft of the motor 55 drives the screw 56 to rotate. The screw 56 is threadedly connected to the sleeve 57, thereby adjusting the distance between the motor 55 and the fixed cylinder 51. The positioning ring 52 is rotatably connected to the fixed cylinder 51, so that when the angle of the mounting frame 3 changes, it can maintain the connection with the fixed cylinder 51 through the sleeve 57. The moving mounting roller 2 is slidably connected to the slider 53 through the arc-shaped groove 54, thereby enabling it to rotate and change angle independently. This allows the photovoltaic panel 4 to change its angle. When the simulated satellite 1 approaches or moves away from the sun, the temperature changes, causing the gas volume inside the drive cylinder 65 to change. This change in air volume inside the drive cylinder 65 drives the piston block 66 to move back and forth, which in turn drives the top rod 67 and the drive rod 61 to move. The drive rod 61 drives the telescopic rod 63 to move, thereby adjusting the number of photovoltaic panels 4 connected by cooperating with the wiring rod 62. This reduces the number of photovoltaic panels 4 connected when the temperature is high and increases the number of photovoltaic panels 4 connected when the temperature is low, preventing the power supply from being overloaded due to excessive temperature.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
