Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic devices, and specifically to a photovoltaic device with self-adjusting ability. Background Art

[0002] A photovoltaic device is a power generation device that generates direct current when exposed to sunlight. It consists of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). When sunlight shines on the photovoltaic panel, solar energy can be converted into electrical energy for use. However, the photovoltaic panel is fixedly installed and cannot adjust the angle of the photovoltaic panel following the rotation of the sun, so that the photovoltaic panel cannot fully utilize sunlight.

[0003] For this reason, the Chinese patent with the publication number "CN219918819U" discloses "a solar photovoltaic panel capable of automatic adjustment". Its main structure includes a mounting plate, a support plate and a mounting table. A first connection block is installed on the top of the mounting plate, a support plate is installed on the top of the mounting plate, a second connection block is installed on the front of the support plate, and a mounting table is installed on the top of the mounting plate. A driving motor is installed on the front of the mounting table through bolts. A connecting rod is installed on the top of the mounting plate through the first connection block. A connection fixing member is arranged on the outer side of the connecting rod, and a mounting frame is installed on the outer side of the connection fixing member. For this solar photovoltaic panel capable of automatic adjustment, the controller is used to regularly control the operation of the driving motor, so that it drives the photovoltaic panel to rotate a certain angle every once in a while. After the driving motor is powered on, it converts electrical energy into kinetic energy, drives the first connecting wheel to rotate, and under the connection action of the transmission belt, makes the second connecting wheel rotate, thereby driving the connecting rod to rotate. Since both ends of the connecting rod are movably connected to the first connection block and the second connection block through connecting shafts, the connecting rod can rotate. Since the connecting rod is connected to the mounting frame through the connection fixing member, the mounting frame is driven to rotate. The photovoltaic panel body is located in the mounting frame, and the angle of the photovoltaic panel body can be adjusted following the movement of the sun.

[0004] Obviously, when adjusting the angle of the photovoltaic panel body of the above-mentioned solar photovoltaic panel capable of automatic adjustment, it is realized by the controller that is constantly working sending signals to the driving motor. The controller that is constantly working itself will cause waste of electricity, and the operation of the driving motor will cause power output again. At the same time, since the controller is constantly working, the waste of electricity caused by it is relatively large. At the same time, the adjustment angle of the above-mentioned photovoltaic panel body is relatively narrow, and for workplaces near the equator, the phenomenon of insufficient angle adjustment will occur. Summary of the Invention

In addition, the device can make the driving motor drive the photovoltaic panel body to quickly reset, thereby reducing the power consumption of the device itself.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 and Figure 2, a photovoltaic device with self - regulating ability, including a photovoltaic panel mounting frame 2 installed with a photovoltaic panel body 1, two first rotating shafts 3 arranged on the outer side of the middle area of the photovoltaic panel mounting frame 2, a first support base 4 installed around the first rotating shaft 3 through bearings and playing a supporting role, a central fixed shaft 5 fixedly installed between the two first support bases 4, and a pin shaft structure 6 fixedly installed at both ends of the photovoltaic panel mounting frame 2 in the length direction. The first support base 4 and the bottom mounting substrate 71 are fixedly installed on the ground or the workbench surface. Among them, the flipping angle of the photovoltaic panel body 1 needs to be consistent with the movement route of the sun.

[0021] To achieve the driving - type reset function of the photovoltaic panel body 1, please refer to Figure 1 , Figure 2 and Figure 3 , it is necessary to set up a winch - type traction mechanism 7, which internally has a winch wheel 76 installed below the photovoltaic panel mounting frame 2 and capable of rotating, a cable 78 installed between the winch wheel 76 and one of the pin shaft structures 6 and capable of being wound around the winch wheel 76, and a driving motor 73 capable of driving the winch wheel 76 to rotate in a specific direction. When the sun rises, the driving motor 73 is started, and the rotor 74 drives the winch wheel 76 to wind. This winding causes the cable 78 to pull the photovoltaic panel mounting frame 2 to flip until the photovoltaic panel mounting frame 2 and the photovoltaic panel body 1 can no longer flip. At this time, the absorption surface of the photovoltaic panel body 1 needs to face the angle when the sun rises, so as to achieve the driving - type reset function of the photovoltaic panel body 1.

[0022] Regarding the specific structure of the winch - type traction mechanism 7, please refer to Figure 3 , including a bottom mounting substrate 71. On the upper surface of the bottom mounting substrate 71, there are fixedly installed an opposing second support base 72 and a third support base 75. On the top of the second support base 72, a driving motor 73 is fixedly installed. On the top of the third support base 75, a winch wheel 76 is installed through bearings and can indirectly rotate with the rotor 74 of the driving motor 73. The winch wheel 76 is provided with a first shaft body fixing groove 77 with an in - concave structure at the end facing the rotor 74. The cable 78 is wound in the concave area of the winch wheel 76. One end of the cable 78 is fixedly installed with a first sleeve 79, and the sleeve hole of the first sleeve 79 is sleeved around the outer periphery of the shaft of one of the pin shaft structures 6. When the driving motor 73 is turned off and paused, its rotor 73 can be driven to rotate by an external force.

[0023] To achieve the driving function of the energy - storage type photovoltaic panel body 1, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, it is necessary to set up a controllable telescopic mechanism 8, which is internally provided with a hollow rod body 81 and an axial telescopic rod 88 that expand and contract relative to the movement of the photovoltaic panel mounting frame 2 and the central fixed shaft 5, a first helical spring 89 capable of causing the hollow rod body 81 and the axial telescopic rod 88 to contract, and a second gas flow hole 810 capable of controlling the speed of the hollow rod body 81 and the axial telescopic rod 88 during contraction by controlling the gas flow rate. When the cable 78 pulls the photovoltaic panel mounting frame 2 to flip, the outside gas will simultaneously enter the inside of the first component activity cavity 83 along the first gas flow hole 85 and the second gas flow hole 810, thereby reducing the resistance of the gas negative pressure to the flipping movement of the photovoltaic panel body 1. At the same time, the hollow rod body 81 and the axial telescopic rod 88 extend until the first helical spring 89 is compressed to the end of the movement, and then the driving motor 73 is turned off. At this time, the elastic potential energy of the first helical spring 89 is released, which will cause the hollow rod body 81 and the axial telescopic rod 88 to have a contraction trend. At the same time, the piston plate 87 will move, and the movement of the piston plate 87 will cause the gas at one end of it to be compressed. The compressed gas can only be discharged outward along the second gas flow hole 810, and the resistance formed by the air flow movement will delay the speed of the hollow rod body 81 and the axial telescopic rod 88 during contraction. By controlling the aperture of the second gas flow hole 810, the flipping speed of the photovoltaic panel body 1 following the movement of the sun can be controlled. Using this principle, the flipping angle of the photovoltaic panel body 1 is kept consistent with the travel during the movement of the sun until the sun goes down and the flipping of the photovoltaic panel body 1 is completed, thereby realizing the driving function of the energy storage type photovoltaic panel body 1.

[0024] For the specific structure of the controllable telescopic mechanism 8, please refer to Figure 4 and Figure 5, including a hollow rod body 81, one end of the hollow rod body 81 is provided with a second sleeve 82 of an integral structure therewith, the socket hole of the second sleeve 82 is sleeved around the outer periphery of the shaft body of another pin shaft structure 6, a first component moving cavity 83 is arranged inside the second sleeve 82, the other end of the second sleeve 82 is provided with a first shaft body through hole 84 communicating the external space and one end face of the first component moving cavity 83, the hollow rod body 81 is provided with a first gas flow hole 85 communicating the external space and the other end of the first component moving cavity 83 inside the second sleeve 82, a gas check valve 86 is installed inside the hollow rod body 81 at the position of the first gas flow hole 85, a piston plate 87 capable of moving axially along the first component moving cavity 83 is placed inside the hollow rod body 81 at the position of the first component moving cavity 83, an axial telescopic rod 88 penetrating the first shaft body through hole 84 is fixedly installed on one end face of the piston plate 87 facing the first shaft body through hole 84, a third sleeve 811 is fixedly installed at the end of the axial telescopic rod 88 outside the hollow rod body 81, the socket hole of the third sleeve 811 is sleeved around the outer periphery of the central fixed shaft 5, a second gas flow hole 810 with both ends in an open state and one end close to the third sleeve 811 is arranged inside the axial telescopic rod 88 and the piston plate 87, a first spiral spring 89 is sleeved around the rod body of the axial telescopic rod 88 inside the first component moving cavity 83, the air inlet of the gas check valve 86 is close to the second sleeve 82, the air outlet of the gas check valve 86 is close to the first component moving cavity 83, the aperture of the first gas flow hole 85 is larger than the aperture of the second gas flow hole 810, the initial length of the first spiral spring 89 is greater than the axial depth of the first component moving cavity 83, and the elastic strength of the first spiral spring 89 after compression is sufficient to drive the photovoltaic panel body 1 to turn during operation.

[0025] To prevent damage to components caused by excessive torque strength formed by the drive motor 73, please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8, it is necessary to set up a detachable linkage mechanism 9, which is provided with a hollow disk body 91 that can rotate with the rotor 74, an inner rotating column 910 that can drive the winch wheel 76 to rotate, and an arc-shaped contact plate 99 that can link the hollow disk body 91 and the inner rotating column 910 by friction. When the cable 78 pulls the photovoltaic panel mounting frame 2 to flip to the end of the stroke, the resistance between the hollow disk body 91 and the inner rotating column 910 will increase. When the torque resistance is greater than the force formed by the maximum static friction between the inner rotating column 910 and the arc-shaped contact plate 99, the rotor 74 will rotate normally, and relative rotation will occur between the hollow disk body 91 and the arc-shaped contact plate 99, which will not cause the torque resistance to continue to increase, thereby preventing the torque strength formed by the drive motor 73 from being too large and causing damage to the components.

[0026] For the specific structure of the detachable linkage mechanism 9, please refer to Figure 6 , Figure 7 and Figure 8 , including a hollow disk body 91 and an inner rotating column 910, one end surface of the hollow disk body 91 is provided with a No. 2 shaft body fixing groove 92 for fixing and installing the rotor 74, the center of the hollow disk body 91 is provided with a columnar component mounting cavity 93, the bottom center of the hollow disk body 91 is provided with a No. 1 shaft body mounting hole 94, the interior of the No. 1 shaft body mounting hole 94 is fixedly installed with a No. 2 rotating shaft 912 through a bearing, the center of the columnar component mounting cavity 93 is provided with an inner rotating column 910, one end of the inner rotating column 910 is provided with a No. 3 shaft body fixing groove 911 for installing the No. 2 rotating shaft 912, the other end of the No. 2 rotating shaft 912 is fixedly installed inside the No. 1 shaft body fixing groove 77, the hollow disk body 91 is provided with a plurality of No. 2 component active cavities 95 in an annular array at the periphery of the columnar component mounting cavity 93, the No. 2 component active cavities 95 and the columnar component The circumferential side surfaces of the mounting cavity 93 are connected through the No. 1 and No. 2 shaft body through-holes 96. The hollow disk body 91 is provided with an inner movable plate 97 capable of axially moving along the cylindrical component mounting cavity 93, and a No. 2 coil spring 98 is placed at one end of the inner movable plate 97. A connecting shaft body penetrating the No. 1 and No. 2 shaft body through-holes 96 is fixedly installed at the other end of the inner movable plate 97. An arc-shaped contact plate 99 that abuts against the circumferential surface of the inner rotating column 910 is fixedly installed at one end of the connecting shaft body located inside the cylindrical component mounting cavity 93. One end of the No. 2 coil spring 98 abuts against one end surface of the inner movable plate 97, and the other end abuts against one end surface of the No. 2 component movable cavity 95. The No. 2 coil spring 98 is in a compressed state, and the structural radius of the inner concave surface of the arc-shaped contact plate 99 matches the structural radius of the inner rotating column 910.

[0027] In use, the first support base 4 and the bottom mounting substrate 71 are fixedly installed on the ground or the workbench surface. The flipping angle of the photovoltaic panel body 1 needs to be consistent with the movement route of the sun. When the sun rises, the driving motor 73 is started, and the rotor 74 drives the winding pulley 76 to wind. This winding causes the cable 78 to pull the photovoltaic panel mounting frame 2 to flip. At the same time, the outside air will enter the inside of the first component activity cavity 83 along the first gas flow hole 85 and the second gas flow hole 810, thereby reducing the resistance of the gas negative pressure to the flipping movement of the photovoltaic panel body 1. At the same time, the hollow rod body 81 and the axial telescopic rod 88 extend until the first spiral spring 89 is compressed to the end of the movement, and then the driving motor 73 is turned off. At this time, the absorption surface of the photovoltaic panel body 1 needs to face the angle when the sun rises. At this time, the elastic potential energy of the first spiral spring 89 is released, which will cause the hollow rod body 81 and the axial telescopic rod 88 to tend to contract. At the same time, the piston plate 87 will move. The movement of the piston plate 87 will cause the gas at one end of it to be compressed. The compressed gas can only be discharged outward along the second gas flow hole 810. The resistance formed by the air flow movement will slow down the speed of the hollow rod body 81 and the axial telescopic rod 88 during contraction. By controlling the aperture of the second gas flow hole 810, the flipping speed of the photovoltaic panel body 1 following the movement of the sun can be controlled. Using this principle, the flipping angle of the photovoltaic panel body 1 is kept consistent with the travel when the sun moves until the sun sets and the flipping of the photovoltaic panel body 1 is completed.
