[0002] Photovoltaic solar panels, also known as solar panels, are a type of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. The working principle of photovoltaic solar panels is based on the photovoltaic effect, that is, when sunlight shines on semiconductor materials (such as silicon), photons will excite electrons in the material, causing them to jump from the valence band to the conduction band, thereby generating current. In this process, light energy is directly converted into electrical energy, so photovoltaic solar panels need to be regularly maintained and serviced to ensure their long-term stable operation. At the same time, in order to improve the efficiency of photovoltaic power generation, the direction of the photovoltaic solar panels is adjusted so that they can receive direct sunlight, thereby increasing power generation.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 and Figure 2 As shown, a steering device capable of adjusting the direction of a photovoltaic solar panel comprises a base 1, a fixing mechanism 5 is rotatably connected to the middle of the upper end of the base 1, a retraction mechanism 3 is symmetrically arranged on the upper part of the fixing mechanism 5, three photovoltaic panels 4 are fixedly connected to the two retraction mechanisms 3, a transmission mechanism 6 is fixedly connected to the front side of the upper end of the base 1, and a cleaning mechanism 2 is symmetrically arranged on the upper end of the base 1.

[0034] When installing the photovoltaic solar panel, the inclination angle of the fixing mechanism 5 is adjusted according to the geographical location of the installation, and the entire device is fixed to the ground through the base 1, so that the fixing mechanism 5 cooperates with the two retracting mechanisms 3 to drive the three photovoltaic panels 4 during operation, which can ensure that the photovoltaic solar panel is always facing the sun, thereby capturing more sunlight and converting it into electrical energy. At the same time, the transmission mechanism 6 drives the fixing mechanism 5 to rotate, so that the three photovoltaic panels 4 always track the position of the sun in real time. Similarly, the transmission mechanism 6 can cooperate with the cleaning mechanism 2 to clean the surface of the three photovoltaic panels 4 to avoid the situation where dust accumulated on the photovoltaic panels 4 during long-term operation affects the solar energy that can be captured by the photovoltaic panels 4. At the same time, the cleaning mechanism 2 and the retracting mechanism 3 cooperate to gather or unfold the three photovoltaic panels 4 to avoid damage to the surface of the photovoltaic panels 4 caused by extreme weather such as rain and snow, thereby affecting the service life of the photovoltaic panels 4.

[0035] During the operation of this embodiment, the fixing mechanism 5 cooperates with the transmission mechanism 6 to ensure that the photovoltaic panel 4 is always facing the sun, and at the same time, the photovoltaic panel 4 can achieve smooth and impact-free rotation when adjusting the angle. Similarly, the retraction mechanism 3 cooperates with the cleaning mechanism 2 to clean the surface of the photovoltaic panel 4 before folding it up, so as to avoid dust and dirt accumulated on the surface that will reduce the photoelectric conversion efficiency, and to protect the surface of the photovoltaic panel 4 from being scratched or broken in extreme weather, thereby ensuring the normal operation of the system.

[0036] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve precise adjustment of the angle of the photovoltaic panel 4 to ensure that the photovoltaic panel 4 is always facing the sun, thereby maximizing the effect of power generation efficiency.

[0037] See also Figure 3 A guide groove 11 is provided at the upper end of the base 1, and a limiting groove 12 is provided at the left side of the upper end of the base 1.

[0038] By cooperating with the cleaning mechanism 2 through the guide groove 11, when adjusting the orientation of the entire photovoltaic panel 4, there will be no overall position deviation.

[0039] See also Figure 3 The transmission mechanism 6 includes a motor 61 fixedly connected to the upper end of the base 1, a one-way rotating shaft 3 64 is fixedly connected to the middle of the outer surface of the output end of the motor 61, a one-way rotating shaft 2 63 is fixedly connected to the left side of the outer surface of the output end of the motor 61, a worm 62 is fixedly connected to the outer surface of the one-way rotating shaft 3 64, a friction wheel 3 65 is fixedly connected to the outer surface of the one-way rotating shaft 2 63, and the outer surface of the friction wheel 3 65 is in close contact with the inner surface of the limiting groove 12.

[0040] The one-way rotating shaft 2 63 and the one-way rotating shaft 3 64 are both conventionally designed in the prior art, and are composed of an outer ring, an inner ring, a roller, and a spring. The working principle is as follows:

[0041] Outer ring: usually fixed to the housing or connected to other components to form a cylinder-like structure;

[0042] Inner ring: The structure of the inner ring is relatively special. It has a circle with a slope. This slope is a one-way shaft that realizes one-way rotation and locking functions.

[0043] Roller: The roller is always in contact with the inner and outer rings, and its working surface is also a slope;

[0044] Spring: The spring is in contact with the roller to maintain the position of the roller and provide a return force when needed;

[0045] Therefore, the one-way rotating shaft 2 63 and the one-way rotating shaft 3 64 mentioned above are conventional arrangements in the prior art and will not be elaborated in detail in this solution.

[0046] After the installation is completed, the motor 61 is stimulated to run. Through the setting of the one-way shaft three 64 and the one-way shaft two 63, when the output end of the motor 61 rotates forward, the output end of the motor 61 drives the one-way shaft three 64 to rotate, thereby causing the worm 62 to rotate. At this time, the one-way shaft two 63 and the friction wheel three 65 are in a non-rotating state. When the output end of the motor 61 reverses, the one-way shaft three 64 and the worm 62 do not rotate, and the one-way shaft two 63 and the friction wheel three 65 rotate.

[0047] See also Figure 4 The fixing mechanism 5 includes a support shaft 51 rotatably connected to the middle part of the upper end of the base 1, a worm gear 52 is fixedly connected to the middle part of the outer surface of the support shaft 51, the outer surface of the worm gear 52 is meshed with the worm 62, and a U-shaped support plate 53 is fixedly connected to the upper end of the support shaft 51.

[0048] Furthermore, when the output end of the motor 61 rotates forward, the worm 62 is driven to rotate, and then the worm wheel 52 is driven to rotate through meshing, and then the worm wheel 52 will drive the support shaft 51 and the U-shaped support plate 53 to rotate in the same direction, that is, the photovoltaic panel 4 can be smoothly rotated in the horizontal direction to adjust the angle, and then the sun can be tracked in real time, so that the optimal illumination angle between the photovoltaic panel 4 and the sun is achieved, thereby improving the photoelectric conversion efficiency.

[0049] When the worm wheel 52 cooperates with the worm 62 to drive the U-shaped support plate 53 and the support shaft 51 to rotate, the three photovoltaic panels 4 as well as the cleaning mechanism 2 and the retracting mechanism 3 are driven to rotate around the axis of the worm wheel 52 as a whole.

[0050] See also Figure 4 A rectangular through hole 531 is provided at the front upper part of the two vertical parts of the U-shaped support plate 53, and a guide block 532 is fixedly connected to the upper end of the horizontal part of the U-shaped support plate 53.

[0051] Furthermore, during the installation of the photovoltaic panel 4, the inclination angle of the vertical portion of the U-shaped support plate 53 is adjusted according to the longitude and latitude of the desired installation location, that is, the inclination angle of the photovoltaic panel 4 in the vertical direction after installation is adjusted.

[0052] Then, during use, rain, snow, etc. falling on the upper end of the horizontal portion of the U-shaped support plate 53 are guided through the rectangular through hole 531 to avoid damage to the entire device.

[0053] Therefore, this solution achieves smooth adjustment of the angle of the photovoltaic panel 4 through the worm 62 in conjunction with the worm wheel 52 and the U-shaped support plate 53, ensuring that the photovoltaic panel 4 will not be damaged by vibration or impact during the adjustment process. At the same time, it can also ensure that the photovoltaic panel 4 always remains at the best angle for receiving solar energy, thereby improving the utilization efficiency of solar energy.

[0054] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment can realize the effect of folding the photovoltaic panels 4 while cleaning them to prevent them from being damaged by extreme weather.

[0055] See also Figure 5 The contraction mechanism 3 includes three gears 31 rotatably connected to the inner surface of a rectangular through hole 531, and the upper parts of the outer surfaces of the three gears 31 are fixedly connected with triangular support plates 37, and the left parts of the outer surfaces of the two gears 31 located on the right side of the inner surface of the rectangular through hole 531 are meshed with gears 2 32, and the outer surface of the gear 31 located on the left side of the inner surface of the rectangular through hole 531 is meshed with gear 35, and the left parts of the outer surfaces of the two gears 2 32 are fixedly connected with rectangular plates 1 33, and the left parts of the rear sides of the two rectangular plates 1 33 are rotatably connected with rectangular plates 2 34, and the lower part of the outer surface of the gear 1 31 located on the right side of the inner surface of the rectangular through hole 531 is meshed with gear 4 36, and the two rectangular plates 2 34 are respectively fixedly connected to the rear sides of the two matching gears 31, and the two triangular support plates 37 on the same side are jointly fixedly connected with the photovoltaic panel 4, and the middle part of the rear end of the gear 4 36 is fixedly connected with the friction wheel 2 361.

[0056] Specifically, when the three photovoltaic panels 4 are working normally, the two gears 1 31 on the same side cooperate with the triangular support plate 37 to support the photovoltaic panel 4, the two gears 2 32 are meshed with the two gears 1 31, and the one gear 35 is meshed with the gear 1 31. At the same time, the two rectangular plates 2 34 cooperate with the two gears 2 32 and the three gears 1 31 to support the triangular support plate 37 and the photovoltaic panel 4.

[0057] See also Figure 6 and Figure 7The cleaning mechanism 2 includes four fixed columns 21 slidably connected to the inner surface of the guide groove 11, and the four fixed columns 21 are symmetrically arranged. The two fixed columns 21 on the same side are connected to the bidirectional screw rod 22 for rotation together. The left sides of the outer surfaces of the two bidirectional screw rods 22 are slidably connected to rectangular sliders 23. The two rectangular sliders 23 are fixedly connected to a cleaning plate 24. A friction wheel 25 is arranged at the left end of the front bidirectional screw rod 22, and the outer surface of the friction wheel 25 is in close contact with the outer surface of the friction wheel 3 65.

[0058] Furthermore, when the three photovoltaic panels 4 are working normally, the horizontal angles of the three photovoltaic panels 4 are adjusted by the worm gear 52 cooperating with the worm 62, which will drive the cleaning mechanism 2 as a whole to rotate in the same direction as the U-shaped support plate 53 and the three photovoltaic panels 4. At this time, the four fixed columns 21 slide along the inner surface of the guide groove 11, and the output end of the motor 61 rotates forward to adjust the horizontal rotation of the photovoltaic panel 4. When the friction wheel 25 rotates to be in close contact with the outer surface of the friction wheel three 65, the friction wheel 25 is driven to continue to rotate around the axis of the worm gear 52. The friction wheel three 65 cooperates with the friction wheel 25 to make the friction wheel 25 rotate itself. At this time, only the friction wheel 25 rotates, and the cleaning plate 24 is located on the left part of the upper end of the left photovoltaic panel 4. The two rectangular sliders 23 are both located on the left side of the bidirectional screw 22, and the three photovoltaic panels 4 are adjusted in angle around the axis of the worm gear 52 in real time following the direction of the sun.

[0059] See also Figure 6 The left ends of the two fixed columns 21 on the right side are fixedly connected with guide rods 211, and the two guide rods 211 are respectively slidably connected with the adapted rectangular sliders 23. The upper ends of the two rectangular sliders 23 are fixedly connected with friction plates 231. The two rectangular sliders 23 are fixedly connected with fixed rods 232 on the sides away from each other. The two fixed rods 232 are fixedly connected with the cleaning plate 24 together. The inner surface of the friction wheel 25 is fixedly connected with a roller 251, and the right end of the roller 251 is fixedly connected with a one-way shaft 221. The outer surface of the one-way shaft 221 is fixedly connected to the bidirectional screw rod 22 on the front side, and a transmission device is arranged between the two bidirectional screw rods 22.

[0060] See also Figure 7 The one-way rotating shaft 1 221 mentioned above and the one-way rotating shaft 3 64 and the one-way rotating shaft 2 63 mentioned above are devices of the same principle, and will not be described again in this solution;

[0061] At the same time, power is transmitted between the two bidirectional screw rods 22 through a transmission device in the prior art.

[0062] Furthermore, when the output end of the motor 61 rotates forward and drives the photovoltaic panel 4 to adjust its horizontal direction, when the friction wheel 25 and the friction wheel 3 65 are in close contact and drive the friction wheel 25 to rotate, the friction wheel 25 will drive the roller 251 to rotate, and then the bidirectional screw rod 22 will not rotate at this time through the matching setting of the one-way rotating shaft 221 and the roller 251.

[0063] Furthermore, when the surfaces of the three photovoltaic panels 4 need to be cleaned or the photovoltaic panels 4 need to be folded to avoid damage to the photovoltaic panels 4 due to extreme weather, the motor 61 is reversed, so that the worm 62 does not rotate, and the friction wheel three 65 continues to rotate through the setting of the one-way shaft two 63. At this time, the friction wheel three 65 is in close contact with the surface of the friction wheel one 25. When the friction wheel three 65 rotates, it drives the friction wheel one 25 to rotate in the opposite direction, and then drives the roller 251 to rotate in the opposite direction, and then the roller 251 cooperates with the one-way shaft one 221 to rotate the bidirectional screw rod 22 on the front side, and similarly, the bidirectional screw rod 22 on the rear side is rotated through the transmission device;

[0064] Furthermore, during the rotation of the two bidirectional screw rods 22, the two rectangular sliders 23 slide to the right along the bidirectional screw rods 22 through the two guide rods 211, and at the same time, the cleaning plate 24 fixed by the two fixing rods 232 slides to the right along the upper ends of the three photovoltaic panels 4, see Figure 8 , wiping and cleaning the upper end of the photovoltaic panel 4 during the sliding process;

[0065] See also Fig.10 The upper ends of the two friction plates 231 can be in close contact with the outer surface of the matching friction wheel 2 361 .

[0066] When the two rectangular sliders 23 continue to slide to the right until the upper end of the friction plate 231 begins to cling to the outer surface of the matching friction wheel 2 361, at this time, the lower end of the cleaning plate 24 is just separated from the upper end of the right photovoltaic panel 4, and then the rectangular slider 23 continues to drive the friction plate 231 to move to the right, and then the friction plate 231 cooperates with the friction wheel 2 361 to rotate the friction wheel 2 361, which in turn causes the gear 4 36 to rotate, and then the gear 4 36 drives the gear 1 31 to rotate in the opposite direction by a certain angle through meshing, and then the gear 1 31 located on the right side of the inner surface of the two rectangular through holes 531 rotates, driving the triangular support plate 37 and the photovoltaic panel 4 on the right side to rotate and lift up;

[0067] At the same time, during the rotation of gear 1 31, gear 2 32 on the right side of the inner surface of the rectangular through hole 531 is driven to rotate through meshing, thereby causing rectangular plate 1 33 to rotate downward around the axis of gear 2 32, and while rectangular plate 1 33 rotates downward, rectangular plate 2 34 is driven downward, and rectangular plate 2 34 and gear 1 31 fixedly connected to rectangular plate 2 34 are driven to the right side. Further, while rectangular plate 2 34 is driven downward by rectangular plate 1 33, gear 1 31 located in the middle of the inner surface of the rectangular through hole 531 and gear 1 31 on the right side of the inner surface of the rectangular through hole 531 rotate in the same manner.

[0068] See also Fig. 9 That is, through the meshing of gear 1 31 and gear 2 32, and the cooperation of rectangular plate 1 33 and rectangular plate 2 34, as well as the cooperation of gear 1 31 and gear 3 35 on the left side of the inner surface of the rectangular through hole 531, the six gears 1 31 on both sides drive the six triangular support plates 37 and the three photovoltaic panels 4 to rotate right around the axis of their respective gears 1 31 at the same time. At the same time, the two gears 1 31 located on the left side of the inner surface of the rectangular through hole 531 will gradually move closer to the right side of the inner surface of the rectangular through hole 531 through the cooperation of rectangular plate 1 33 and rectangular plate 2 34, so that the three photovoltaic panels 4 are smoothly folded together.

[0069] When three photovoltaic panels 4 need to be unfolded, the motor 61 continues to reverse and the two bidirectional screws 22 continue to rotate, so that the rectangular slider 23 drives the friction plate 231 to move to the left, and then the friction plate 231 cooperates with the friction wheel 2 361 to make the gear 1 31 drive the triangular support plate 37 and the photovoltaic panel 4 to rotate in the opposite direction, and the three photovoltaic panels 4 are unfolded at the same time. After the gear 1 31 cooperates with the gear 2 32 and the rectangular plate 1 33 and the rectangular plate 2 34 to unfold the three photovoltaic panels 4 again, the two fixing rods 232 cooperate with the cleaning plate 24 to clean the upper end of the photovoltaic panel 4 again to prevent rain or dust on the upper end of the photovoltaic panel 4 from affecting the photoelectric conversion efficiency of the photovoltaic panel 4.

[0070] Therefore, the present invention drives the rectangular slider 23 to move by rotating the bidirectional screw rod 22, so as to wipe and clean the surface of the photovoltaic panel 4 while allowing the photovoltaic panel 4 to more fully receive sunlight and improve power generation efficiency. The friction plate 231 can also cooperate with the friction wheel 2 361 to retract the photovoltaic panel 4, thereby reducing the direct impact of extreme weather on the photovoltaic panel 4 and avoiding the breakage of the photovoltaic panel 4, thereby further protecting the photovoltaic panel 4 from damage. Similarly, retracting the photovoltaic panel 4 in extreme weather can avoid the situation where the power generation efficiency of the photovoltaic panel 4 is reduced due to damage or obstruction, thereby making the output of the photovoltaic power generation system more stable.

[0071] It should be noted that the specific installation method of the motor 61, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
