Description

Technical Field

[0001] The present invention belongs to the technical field of solar power generation, and in particular relates to a photovoltaic panel self-adaptive angle adjustment mechanism. Background Art

[0002] A solar panel is a device that responds to light and converts light energy into electricity. Solar power generation is a common form of clean energy generation.

[0003] For example, the Chinese patent publication number CN113285662A discloses a solar power supply device with a self-adjusting function, including a base, a control shaft is rotatably connected to the center position of the upper end surface of the base, the upper end of the control shaft is fixedly connected to a horizontal rotating plate, the rotating plate is fixedly connected to a vertical support plate, the upper end of the support plate and the rotating plate are jointly fixedly connected to an inclined fixed plate, the inclined surface of the fixed plate is fixedly connected to a solar power generation panel, and a self-driving device is provided in the base.

[0004] The technical solution proposed in this application uses solar energy as the driving force and the change in light angle as the judgment driving condition to automatically adjust the angle of the solar panel, so that the solar panel changes with the change of sunlight, improves the efficiency of the solar panel in converting light energy into electrical energy, and increases the power generation. At the same time, a cleaning mechanism is set up to clean the dust or foreign matter on the surface of the solar panel every day, thereby improving the utilization rate of light energy and increasing the service life of the equipment.

[0005] However, in this application, the angle adjustment of the solar panel is determined by the angle of the light. First, the installation location of the solar panel is determined. According to the longitude and latitude of the installation location, the amount of adjustment of the solar panel tilt angle each day can be determined. The solar panel is evenly divided into several parts according to the duration of the sunlight. The solar panel is driven to rotate a specified angle within a unit time, thereby fully utilizing the solar energy. Therefore, there is no need for complex equipment to detect the angle of sunlight.

[0006] When the solar panels are tilted, the windward area of ​​the solar panels is larger. The solar panels are connected by a self-driving device that drives the gears to rotate, which in turn drives the solar panels to rotate. The existing device cannot effectively fix the solar panels. When strong winds blow, the solar panels will be blown and rotated. In view of this, we propose a photovoltaic panel adaptive angle adjustment mechanism. Summary of the Invention

[0007] The purpose of the present invention is to address the above-mentioned technical problems and provide a photovoltaic panel adaptive angle adjustment mechanism to prevent the photovoltaic panel from rotating due to wind when the photovoltaic panel can rotate.

[0008] The yoke is fixedly mounted on the support frame, and the support frame is fixedly mounted on the support frame to adjust the angle of the photovoltaic panel. The support frame is fixedly mounted on the support frame, and the support frame is fixedly mounted on the support frame to adjust the angle of the photovoltaic panel. The support frame is fixedly mounted on the support frame to adjust the angle of the photovoltaic panel.

[0009] Preferably, a spring telescopic sleeve is fixedly mounted on the upper front end of the rotating frame, and the free end of the spring telescopic sleeve is located below the rear end of the solar mounting panel.

[0010] Preferably, the bidirectional hydraulic pull rod includes a sleeve, the interior of the sleeve is slidably connected to a piston pad, both sides of the piston pad are filled with hydraulic oil, a connecting rod is fixedly installed at one end of the piston pad, the connecting rod extends to the outside of the sleeve, and the ball head is fixedly installed at one end of the outside of the connecting rod, and both ends of the sleeve are respectively provided with connecting ports for liquid inlet and discharge.

[0011] Preferably, both ends of the piston pad are provided with protrusions, and the length of the protrusions is greater than the diameter of the communicating port.

[0012] Preferably, the outer surface of the connecting port is connected to and penetrated by a solenoid valve, a valve core is provided in the middle of the solenoid valve, a through hole is opened in the middle of the valve core, the valve core and the inner wall of the solenoid valve are fixedly connected by a reset spring, an iron sheet is fixedly installed at one end of the valve core located on the outside of the solenoid valve, an electromagnet for adsorbing the iron sheet is fixedly installed on the outside of the solenoid valve, the two solenoid valves are connected and penetrated by a DC bidirectional pump, and the electromagnet and the DC bidirectional pump are connected to the circuit together.

[0013] Preferably, a threaded column is fixedly installed at one end of the connecting rod located outside the sleeve, the outer surface of the threaded column is threadedly connected to the threaded sleeve, the ball head is fixedly connected to the threaded sleeve, and a fracture groove is opened on the surface of the threaded sleeve.

[0014] Preferably, a rotating boss is fixedly mounted on the bottom end of the rotating frame, and a rotating groove for accommodating the rotating boss is opened in the middle of the upper surface of the fixed frame.

[0015] Preferably, a controller is connected to the circuit of the electromagnet and the DC bidirectional pump, which controls the power-on time, power-on direction and power-on duration, wherein the electromagnet and the DC bidirectional pump corresponding to the rotating frame are controlled separately from the electromagnet and the DC bidirectional pump corresponding to the support platform.

[0016] Preferably, the signal input end of the controller is connected to a detector for monitoring the amount of electricity stored in the existing electricity storage device, and the detector transmits the detection signal to the controller.

[0017] The beneficial effects of the present invention are:

[0018] 1. This photovoltaic panel adaptive angle adjustment mechanism can change the inclination angle of the solar panel by raising and lowering the bidirectional hydraulic pull rod set on the rotating frame, and can change the rotation angle of the solar panel by extending and retracting the bidirectional hydraulic pull rod set above the support platform. At the same time, it is limited that both ends of the piston pad inside the bidirectional hydraulic pull rod are filled with hydraulic oil. Only during the adjustment process can the connecting port be opened to change the volume of the hydraulic oil, thereby ensuring that the piston pad will not move under the action of external force, thereby avoiding the problem of the solar panel rotating due to wind.

[0019] 2. This photovoltaic panel adaptive angle adjustment mechanism can change the telescopic state of the bidirectional hydraulic pull rod by setting a solenoid valve and a DC bidirectional pump according to the direction of power supply, and can change the telescopic amount of the bidirectional hydraulic pull rod by changing the passage time. Through such a setting, multiple groups of solar panels can be easily controlled to adjust to the optimal irradiation angle at the same time.

[0020] 3. This photovoltaic panel adaptive angle adjustment mechanism has a controller whose signal input is connected to a detector that monitors the charge level of the existing energy storage device. The detector transmits a detection signal to the controller. After the energy storage device is fully charged, the charging circuit is separated from the storage circuit. By detecting the energy storage device's charge level and comprehensively analyzing the power generation potential during the remaining sunlight exposure time, the controller is driven to adjust the tilt angle of the solar panel, ensuring that the solar panel is not within the optimal sunlight range and that the energy storage device is fully charged within the remaining sunlight exposure time. This reduces the need for frequent circuit disconnections to avoid overcharging.

[0021] 4. This photovoltaic panel adaptive angle adjustment mechanism features protrusions on both ends of the piston pad, with the protrusions being longer than the diameter of the communication port. These protrusions limit the piston pad's movement, preventing it from directly contacting the inner wall of the sleeve. By limiting the piston pad's range of motion, the protrusions ensure a gap between the piston pad and the inner wall of the sleeve for hydraulic oil exchange. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figures 1-8 This application is described in further detail.

[0033] In this application, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," and "horizontal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0034] The embodiment of the present application discloses a photovoltaic panel adaptive angle adjustment mechanism, including a fixed frame 1, a plurality of equally spaced rotating frames 2 are rotatably connected above the fixed frame 1, a hinged support rod 3 is fixedly installed in the middle of the rotating frame 2, a hinged block 4 is hinged in the middle of the hinged support rod 3, a solar mounting panel 11 is fixedly installed at the front end of the hinged block 4, and such an arrangement enables the panel to swing along the center of the hinged block 4, and to swing within a range every day to adapt to the changes in the sun, the rear end of the fixed frame 1 is located at the rear end of the rotating frame 2 and a support platform 6 is fixedly installed, and two annular guide rails 7 are fixedly installed at the rear end of the solar mounting panel 11, the annular guide rail 7 is concentric with the central axis of the hinged block 4, the outer surface of the annular guide rail 7 is slidably connected to a connecting block 8, and the connecting block 8 is away from the annular guide rail. One end of the guide rail 7 is fixedly installed with a limiting guide rail 9, and the rear end of the solar mounting panel 11 is fixedly installed with a center guide rail 10 perpendicular to the limiting guide rail 9. A two-way hydraulic pull rod 5 whose telescopic length can be remotely adjusted is fixedly installed in the middle of the support platform 6 and above the rotating frame 2. A ball head 12 is fixedly installed at the sliding end of the two-way hydraulic pull rod 5. One two-way hydraulic pull rod 5 extends and the other two-way hydraulic pull rod 5 contracts, thereby enabling the solar mounting panel 11 to rotate. Changing the telescopic distance of the two-way hydraulic pull rod 5 per unit time can gradually change the rotation angle of the solar mounting panel 11. The ball head 12 corresponding to the rotating frame 2 is slidably connected to the inside of the center guide rail 10, and the ball head 12 corresponding to the support platform 6 is slidably connected to the inside of the limiting guide rail 9.

[0035] Based on the above structure,

[0036] In one embodiment, a spring-loaded telescopic sleeve 13 is fixedly mounted on the upper front end of the rotating frame 2, with the free end of the spring-loaded telescopic sleeve 13 positioned below the rear end of the solar panel 11. Specifically, the free end of the spring-loaded telescopic sleeve 13 can adjust its extension length according to the tilt angle of the solar panel 11.

[0037] In this embodiment, the solar mounting panel 11 can be supported by providing a spring telescopic sleeve 13 .

[0038] Based on the above structure,

[0039] In one embodiment, the bidirectional hydraulic tie rod 5 includes a sleeve 501, with a piston pad 502 slidably connected to the interior of the sleeve 501. Both sides of the piston pad 502 are filled with hydraulic oil. A connecting rod 503 is fixedly mounted on one end of the piston pad 502. The connecting rod 503 extends through the outside of the sleeve 501. The ball head 12 is fixedly mounted on one end of the outside of the connecting rod 503. Both ends of the sleeve 501 are provided with communication ports 504 for liquid inlet and outlet. Specifically, when the piston pad 502 moves, the side closer to it discharges hydraulic oil, while the side farther away replenishes hydraulic oil.

[0040] In this embodiment, such an arrangement can ensure that both sides of the piston pad 502 are filled with hydraulic oil, thereby ensuring that the piston pad 502 cannot move under the action of external force.

[0041] Based on the above structure,

[0042] In one embodiment, both ends of the piston pad 502 are provided with protrusions 505, and the length of the protrusions 505 is greater than the diameter of the communication port 504. Specifically, the protrusions 505 can limit the movement of the piston pad 502, thereby preventing the piston pad 502 from directly contacting the inner wall of the sleeve 501.

[0043] In this embodiment, the protrusion 505 is provided to limit the movement range of the piston pad 502, thereby ensuring that there is a gap between the piston pad 502 and the inner wall of the sleeve 501 for the exchange of hydraulic oil.

[0044] Based on the above structure,

[0045] In one embodiment, the outer surface of the communication port 504 is connected to and penetrated by a solenoid valve 506. A valve core 507 is provided in the middle of the solenoid valve 506. A through hole 508 is opened in the middle of the valve core 507. The valve core 507 is fixedly connected to the inner wall of the solenoid valve 506 by a return spring 509. An iron sheet 510 is fixedly mounted on one end of the valve core 507 located outside the solenoid valve 506. An electromagnet 511 is fixedly mounted on the outside of the solenoid valve 506 for attracting the iron sheet 510. As long as power is applied, the iron sheet 510 can be attracted to drive the valve core 507 to move regardless of the direction of power supply. Only after the valve core 507 moves can the hydraulic oil be exchanged. The two solenoid valves 506 are connected and penetrated by a DC bidirectional pump 515. The electromagnet 511 and the DC bidirectional pump 515 are connected to the circuit. Specifically, the direction of the current can be changed to change the pumping direction of the DC bidirectional pump 515, thereby changing the direction of the hydraulic oil exchange.

[0046] In this embodiment, the extension and contraction state of the bidirectional hydraulic pull rod 5 can be controlled by passing current in different directions into the circuit, thereby adjusting the rotation angle of the solar mounting panel 11.

[0047] Based on the above structure,

[0048] In one embodiment, a threaded post 512 is fixedly mounted on one end of the connecting rod 503 outside the sleeve 501. A threaded sleeve 513 is threadedly connected to the outer surface of the threaded post 512. The ball head 12 is fixedly connected to the threaded sleeve 513. The surface of the threaded sleeve 513 is provided with a fracture groove 514. Specifically, the fracture groove 514 protects the connecting rod 503, preventing the connecting rod 503 and the ball head 12 from separating due to fracture at the fracture groove 514 under extreme stress. The threaded connection facilitates replacement.

[0049] In this embodiment, the provision of the fracture groove 514 enables the device to fracture when subjected to an ultimate tensile force, thereby preventing the bidirectional hydraulic pull rod 5 from being damaged.

[0050] Based on the above structure,

[0051] In one embodiment, a rotating boss 14 is fixedly mounted on the bottom end of the rotating frame 2, and a rotating groove 15 for accommodating the rotating boss 14 is formed in the middle of the upper surface of the fixed frame 1. Specifically, the rotating boss 14 is rotatably connected to the inside of the rotating groove 15.

[0052] In this embodiment, the rotational position of the rotating frame 2 can be limited by providing the rotating boss 14 and the rotating groove 15 .

[0053] Based on the above structure,

[0054] In one embodiment, a controller is connected to the circuits of the electromagnet 511 and the DC bidirectional pump 515. The controller controls the power-on time, power-on direction, and power-on duration. The electromagnet 511 and DC bidirectional pump 515 corresponding to the rotating frame 2 are controlled separately from the electromagnet 511 and DC bidirectional pump 515 corresponding to the support platform 6. Specifically, the electromagnet 511 and DC bidirectional pump 515 corresponding to the rotating frame 2 only need to be adjusted once a day, while the other electromagnets need to be adjusted multiple times a day.

[0055] In this embodiment, the controller can be set to pre-set the adjustment plan for the position in order to obtain the optimal lighting effect. The controller can adjust the tilt angle and rotation angle of multiple groups of solar panels at one time.

[0056] Based on the above structure,

[0057] In one embodiment, a detector for monitoring the charge level of the current energy storage device is connected to the controller's signal input terminal, and the detector transmits a detection signal to the controller. Specifically, after the energy storage device is fully charged, the charging circuit and the storage circuit are separated. By detecting the charge level of the energy storage device and comprehensively analyzing the power generation capacity during the remaining sunlight exposure time, the controller is driven to adjust the tilt angle of the solar panel 11, so that the solar panel 11 is not located within the optimal sunlight range and the energy storage device is fully charged within the remaining sunlight exposure time. This can reduce the need to frequently disconnect the circuit to avoid overcharging.

[0058] When in use, the photovoltaic panel adaptive angle adjustment mechanism of this embodiment can change the inclination angle of the solar mounting panel 11 by raising and lowering the bidirectional hydraulic pull rod 5 arranged on the rotating frame 2, and can change the rotation angle of the solar mounting panel 11 by extending and retracting the bidirectional hydraulic pull rod 5 arranged above the support platform 6. At the same time, it is limited that both ends of the internal piston pad 502 of the bidirectional hydraulic pull rod 5 are filled with hydraulic oil. Only during the adjustment process can the connecting port 504 be opened to change the volume of the hydraulic oil, thereby ensuring that the piston pad 502 will not move under the action of external force, thereby avoiding the problem of the solar mounting panel 11 rotating due to wind.

[0059] By setting the solenoid valve 506 and the DC bidirectional pump 515, the telescopic state of the bidirectional hydraulic pull rod 5 can be changed by the power supply direction, and the telescopic amount of the bidirectional hydraulic pull rod 5 can be changed by changing the passage time. Through such a setting, multiple groups of solar panels can be easily controlled to adjust to the optimal irradiation angle at the same time.
