Description

Technical Field

[0001] The present invention relates to the technical field of solar street lamps, and specifically to a lamp device with a flip - able photovoltaic panel and its method. Background Art

[0002] An outdoor lighting lamp with a flip - able photovoltaic panel is an environmental protection device that combines solar energy utilization and efficient lighting, and is widely used in outdoor places such as courtyards, parks, and roads. Its main functions include energy conservation and emission reduction, improving safety, facilitating installation, and achieving intelligent control. During the day, the solar photovoltaic panel absorbs sunlight and converts it into electrical energy, which is stored in the built - in battery. At night or when the light is insufficient, the stored electrical energy drives the LED lamp to provide lighting. The flip - able design of the panel allows users to adjust the angle according to the sun's position or actual needs to maximize light energy absorption and improve lighting efficiency. Its structure includes a highly efficient and weather - resistant photovoltaic panel, an angle - adjustable rotating bracket, an LED lamp, a power storage system, and an intelligent control circuit to ensure the stability and long - term use of the device. During operation, during the day, the photovoltaic panel absorbs solar energy, converts it into electrical energy and stores it in the battery; at night or when the environment is dark, the sensor detects the brightness and automatically turns on the lamp, and uses the stored electrical energy to continuously provide lighting; For example, a solar street lamp with a flip - able photovoltaic panel disclosed in the authorized publication number CN119436014B includes a street lamp pole and a lamp body installed on the street lamp pole. A sliding sleeve is slidably arranged on the outer side of the street lamp pole, a hexagonal frame is installed on the sliding sleeve, a receiving groove is formed on the side of the hexagonal frame, a flip - plate is arranged in the receiving groove, a photovoltaic panel is arranged on one side of the flip - plate, and an advertising board is arranged on the other side of the flip - plate. A plurality of fixing plates are arranged on the top of the hexagonal frame. By driving the flip - plate to rotate to an inclined state, a water pump pumps water in the receiving cavity to a nozzle for spraying; a rotary driving member drives a worm to rotate, drives the hexagonal frame to rotate around the sliding sleeve, drives the flip - plate to rotate around the axis of the sliding sleeve, and at the same time the flip - plate can also rotate itself, driving the nozzle to spray water on the photovoltaic panels on different flip - plates to achieve the purpose of cleaning the photovoltaic panels. However, the above - mentioned technical solution also adopts a structural form with the lamp on top and the photovoltaic panel at the bottom, which fails to make full use of the protection feature of the large area of the photovoltaic panel, resulting in the lamp being directly exposed to the external environment for a long time and directly affected by natural factors such as rain, dust, bird droppings, and sandstorms. At this time, the exposed lamp is prone to problems such as water leakage, corrosion, and aging, seriously affecting the lighting effect and service life. Summary of the Invention

When the LED lamps do not work during the day, each LED lamp is retracted into the hollow cross shell for hidden protection. At night, the lifting power connection assembly enables the gear speed increasing transmission structure to be power-connected to the C-axis worm and worm gear rotary machine, so that each link-type pushing structure pushes the LED lamp out of the hollow cross shell to be normally lit, thus solving the problems proposed in the above background technology.

[0012] Preferably, the guide sleeves, the sliding rods, the connecting plate, the return frame, and the swing arm are all made of hard plastic components.

[0013] The present invention also provides a method for the photovoltaic panel to be flippable. For the flippable lamp device of the photovoltaic panel as described above, it includes the following steps: S101: During the day, the solar photovoltaic panel absorbs sunlight and converts light energy into electrical energy and stores it in the built-in power storage device. The light sensor continuously monitors the ambient light intensity. When it detects that the daytime light is sufficient, the device enters the standby state. The LED lamp is hidden inside the hollow cross shell and is in a non-working position. The light sensor sends the detected light signal into the central controller. The central controller controls the C-axis worm and worm gear rotary machine and the A-axis worm and worm gear rotary machine to work according to the detected signal to control the horizontal and vertical rotation angles of the fishbone frame and the solar photovoltaic panel; S102: When the sunset or night conditions meet the lighting requirements, the lifting power connection assembly is started under the control of the central controller. At this time, the lifting power connection assembly enables the power combination of the gear speed increasing transmission structure and the C-axis worm and worm gear rotary machine. The rotary power of the drive shaft of the C-axis worm and worm gear rotary machine is transmitted to the four link-type pushing structures inside the hollow cross shell through the gear speed increasing transmission structure. The link-type pushing structure converts the rotational motion into a linear rectilinear motion, thereby pushing the LED lamp out of the hollow cross shell. When the LED lamp is pushed to the limit position, the central controller activates the power supply of the LED lamp to light up the lamp; S103: At dawn, when the light sensor detects that the light has returned to the daytime level, the central controller issues an instruction to start the C-axis worm and worm gear rotary machine to supply rotary power and turn off the power supply of the LED lamp, so that the LED lamp is gradually retracted into the hollow cross shell. After the retraction is completed, the lifting power connection assembly is reset to disconnect the power connection between the gear speed increasing transmission structure and the C-axis worm and worm gear rotary machine.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The lamp device and method with a flipable photovoltaic panel are provided with structures such as a hollow cross shell, a column head, a C-axis worm and worm gear rotary machine, an A-axis worm and worm gear rotary machine, a solar photovoltaic panel, a light sensor, an LED lamp, and a lifting power connection assembly that cooperate with each other. The bottom end of the hollow cross shell is flange bolted to the top end of the lamp post through the column head, and the top end of the hollow cross shell is equipped with a C-axis worm and worm gear rotary machine and an A-axis worm and worm gear rotary machine for controlling the rotation of the solar photovoltaic panel to adjust to the optimal light receiving angle under the detection of the light sensor. When the LED lamp does not work during the day, each LED lamp is retracted into the hollow cross shell for hidden protection. At night, the lifting power connection assembly enables the power combination of the gear speed increasing transmission structure and the C-axis worm and worm gear rotary machine, so that each link-type pushing structure pushes the LED lamp out of the hollow cross shell to be normally lit, thereby achieving the purpose of hiding and protecting the LED lamp during the day, pushing it out at night, and being protected by the solar photovoltaic panel; During the day, all the LED lights are retracted inside the hollow cross-shaped housing, avoiding direct exposure to sunlight, rain, dust, and other environmental factors, greatly reducing the risk of corrosion and aging of the lamps, thus extending the service life of the lamps. In the hidden state, the LED lights are not affected by external mechanical impacts or pollution, reducing the maintenance frequency and cost. When sunset or night conditions meet the lighting requirements, the lifting power connection assembly is activated, driving the gear speed-increasing transmission structure and the link-type pushing structure to receive the rotational power from the C-axis worm gear and worm rotary machine, pushing the LED lights out of the hollow cross-shaped housing and lighting them normally. This process realizes automated operation, avoiding the inconvenience and errors of manual operation, ensuring that the lamps light up in a timely manner when needed, and guaranteeing the continuity and stability of night lighting. At the same time, at night, the solar photovoltaic panel is located above the LED lights, and its sturdy structure can also protect the LED lights from being directly exposed to the environment, reducing the invasion of natural factors such as rain, dust, bird droppings, and sand, and extending the service life of outdoor lamps from the root cause; Secondly, the worm gear and worm transmission structure has good self-locking performance, which can ensure the stability of the LED lights in the hidden and extended states, avoiding misoperation caused by vibration or external forces. Moreover, the spatial arrangement of the C-axis and A-axis worm gear and worm rotary mechanisms enables the photovoltaic panel to accurately track the sun's trajectory. The unique self-locking characteristic ensures that no continuous energy consumption is required to maintain the positioning after the angle adjustment, improving the tracking accuracy and reducing the system power consumption. Finally, the daytime transmission system of the C-axis worm gear and worm rotary machine and the A-axis worm gear and worm rotary machine focuses on the angle adjustment of the photovoltaic panel. At night, through the coupling of the lifting power connection assembly, the gear speed-increasing mechanism and the worm gear, the power is efficiently converted into the linear displacement required for the LED to be pushed out. The link-type pushing structure converts the rotational motion into precise linear motion, ensuring the synchronous and stable extension of multiple groups of LEDs. This design of the time-sharing multiplexing transmission path avoids adding independent drive devices, streamlining the mechanical structure and ensuring the reliability of the actions.

[0018] Embodiment 1, given by Figures 1 to 6 The present invention includes a hollow cross shell 1. A column head 2 is welded at the center position of the bottom end of the hollow cross shell 1. The bottom end of the hollow cross shell 1 is flange bolted to the top end of the lamp post through the column head 2 to ensure that the device can be stably installed at the top end of the lamp post and form a structure with an upper photovoltaic panel and a lower lamp; A C-axis worm and worm gear rotary machine 3 is installed at the center position of the top end of the hollow cross shell 1. The upper end of the drive shaft of the C-axis worm and worm gear rotary machine 3 is installed with an A-axis worm and worm gear rotary machine 4. The lower end of the drive shaft of the C-axis worm and worm gear rotary machine 3 is installed with an upper spline shaft 10. The left and right ends of the drive shaft of the A-axis worm and worm gear rotary machine 4 are both installed with fishbone frames 5, and solar photovoltaic panels 6 are installed on the upper surfaces of the fishbone frames 5. The C-axis worm and worm gear rotary machine 3 and the A-axis worm and worm gear rotary machine 4 realize the horizontal and vertical angle adjustment of the fishbone frames 5 and the solar photovoltaic panels 6. Both of them have high torque transmission and self-locking functions to ensure the stability of the rotation position; The hollow cross-shaped housing 1 serves as the housing of the mechanical structure, providing good mechanical strength to protect the internal gear speed increasing transmission structure 12, the connecting rod type pushing structure 8, and the LED lamp 9; On one side of the top of the fishbone frame 5, a light sensor 7 is installed, and on the inner wall of one side of the column head 2, a central controller 13 is installed. The output ends of the central controller 13 are respectively electrically connected to the input ends of the C-axis worm and worm gear rotary machine 3 and the A-axis worm and worm gear rotary machine 4, and the input end of the central controller 13 is electrically connected to the output end of the light sensor 7; For the connecting rod type pushing structure 8, four connecting rod type pushing structures 8 are annularly and equidistantly installed inside the hollow cross-shaped housing 1. An LED lamp 9 is installed at the moving end of the connecting rod type pushing structure 8. A gear speed increasing transmission structure 12 for power connection is installed between the four connecting rod type pushing structures 8. Inside the column head 2, a lifting type power connection assembly 11 for power combination of the gear speed increasing transmission structure 12 and the upper spline shaft 10 is installed. The input end of the lifting type power connection assembly 11 is electrically connected to the output end of the central controller 13; A method for flipping a photovoltaic panel in this embodiment, such as the lamp device with a flippable photovoltaic panel described above, includes the following steps: S101: During the day, the solar photovoltaic panel 6 absorbs sunlight and converts light energy into electrical energy, which is stored in the built-in power storage device. The light sensor 7 continuously monitors the ambient light intensity. When it detects sufficient daylight, the device enters the standby state. The LED lamp 9 is hidden inside the hollow cross-shaped housing 1 at a non-working position. The light sensor 7 sends the detected light signal into the central controller 13, and the central controller 13 controls the C-axis worm and worm gear rotary machine 3 and the A-axis worm and worm gear rotary machine 4 to work according to the detected signal to control the horizontal and vertical rotation angles of the fishbone frame 5 and the solar photovoltaic panel 6; S102: When the sunset or night conditions meet the lighting requirements, the lifting type power connection assembly 11 is started under the control of the central controller 13. At this time, the lifting type power connection assembly 11 enables the power combination of the gear speed increasing transmission structure 12 and the C-axis worm and worm gear rotary machine 3. The rotary power of the drive shaft of the C-axis worm and worm gear rotary machine 3 is transmitted to the four connecting rod type pushing structures 8 inside the hollow cross-shaped housing 1 through the gear speed increasing transmission structure 12. The connecting rod type pushing structure 8 converts the rotary motion into a linear straight motion, thereby pushing the LED lamp 9 out of the hollow cross-shaped housing 1. When the LED lamp 9 is pushed to the limit position, the central controller 13 activates the power supply of the LED lamp 9 to light up the lamp; S103: At dawn, when the light sensor 7 detects that the light has returned to the daytime level, the central controller 13 issues an instruction to start the C-axis worm and worm gear rotary machine 3 to supply rotary power and turn off the power supply of the LED lamp 9, causing the LED lamp 9 to gradually retract into the hollow cross shell 1. After the retraction is complete, the lifting power connection assembly 11 resets to disconnect the power connection between the gear speed increasing transmission structure 12 and the C-axis worm and worm gear rotary machine 3.

[0019] Embodiment 2, based on Embodiment 1, is given by Figure 7 and Figure 8 The C-axis worm and worm gear rotary machine 3 includes a cylindrical machine shell 301 fixed at the center position of the top end of the hollow cross shell 1, a vertical shaft rotatably installed at the vertical center position inside the cylindrical machine shell 301, and a stepping motor 303 installed on the outer wall of one side of the cylindrical machine shell 301. One end of the drive shaft of the stepping motor 303 extends into the cylindrical machine shell 301 and is equipped with a worm. One end of the surface of the vertical shaft is equipped with a worm gear meshing with the worm. The top end of the vertical shaft is fixed with a turntable 302, and the bottom end of the vertical shaft is fixedly connected to the top end of the upper spline shaft 10. The A-axis worm and worm gear rotary machine 4 is installed on the upper surface of the turntable 302. The input end of the stepping motor 303 is electrically connected to the output end of the central controller 13. When the C-axis worm and worm gear rotary machine 3 is working, the drive shaft of the stepping motor 303 drives the upper spline shaft 10 and the turntable 302 to rotate through the worm and the worm gear, and drives the A-axis worm and worm gear rotary machine 4, the fishbone frame 5, and the solar photovoltaic panel 6 to rotate horizontally through the turntable 302; The lifting power connection assembly 11 includes a base 1101 installed at the center position of the bottom end of the hollow cross shell 1, an electric push rod 1102 installed at the bottom end of the base 1101, and a lower spline shaft 1103 rotatably installed at the top end of the push rod part of the electric push rod 1102. The top end of the lower spline shaft 1103 penetrates to the outside of the hollow cross shell 1 and is coaxial with the upper spline shaft 10. When the lifting power connection assembly 11 needs to couple the gear speed increasing transmission structure 12 and the upper spline shaft 10 for power, the central controller 13 sends a working signal to the electric push rod 1102, causing the electric push rod 1102 to push the lower spline shaft 1103 upward until the upper end of the lower spline shaft 1103 and the lower end of the upper spline shaft 10 are stably docked. At this time, the lower spline shaft 1103 and the upper spline shaft 10 complete the power connection, enabling the C-axis worm and worm gear rotary machine 3 to transmit rotary power to the gear speed increasing transmission structure 12 during operation.

[0020] Embodiment 3, based on Embodiment 2, is given by Figure 9 and Figure 10Given that the gear speed increasing transmission structure 12 includes a hollow shaft sleeve 1201 fixed at the center position of the bottom of the hollow cross shell 1, a middle shaft 1202 rotatably installed inside the hollow shaft sleeve 1201, and a central gear disc 1203 fixed at one end of the surface of the middle shaft 1202. The lower spline shaft 1103 and the middle shaft 1202 are coaxial, and the top end of the lower spline shaft 1103 passes through the middle shaft 1202. There is a straight-mouth notch on one side of the surface of the middle shaft 1202, and a protruding head that penetrates to the outside of the straight-mouth notch is integrally formed at one end of the surface of the lower spline shaft 1103. When the lower spline shaft 1103 moves upward and is docked with the upper spline shaft 10, the C-axis worm and worm rotary machine 3 drives the upper spline shaft 10 and the lower spline shaft 1103 to rotate. Since the lower spline shaft 1103 and the middle shaft 1202 adopt a keyway fit, the middle shaft 1202 and the central gear disc 1203 rotate downward together under the drive of the lower spline shaft 1103, so as to drive the four driven gears 1204 to rotate synchronously through the central gear disc 1203, so as to drive the link-type pushing structure 8 to start operating; The link-type pushing structure 8 includes a driven shaft 801 rotatably installed on one side inside the hollow cross shell 1, a swing arm 802 fixed at one end of the surface of the driven shaft 801, and a link arm 803 slidably installed on one side inside the hollow cross shell 1. A return frame 804 is hinged between the outer wall of one side of the link arm 803 and the end of the swing arm 802. The LED lamp 9 is installed at the bottom end of the link arm 803. A driven gear 1204 that meshes with the central gear disc 1203 is fixed at one end of the surface of the driven shaft 801. Hollowed-out parts for the LED lamp 9 to pass through are provided on the outer walls around the hollow cross shell 1; The link arm 803 includes two guide sleeves fixed on the inner wall of one side of the hollow cross shell 1, sliding rods slidably installed inside the guide sleeves, and a connecting plate fixed jointly at both ends of the two sliding rods. One side outer wall of one of the connecting plates is hinged to one end of the return frame 804. The guide sleeves, the sliding rods, the connecting plate, the return frame 804, and the swing arm 802 are all made of components of hard plastic material. The driven gear 1204 drives the driven shaft 801 to rotate. At this time, the swing arm 802 deflects around the driven shaft 801. During the deflection of the driven shaft 801, the link arm 803 and the LED lamp 9 are gradually moved out of the hollow cross shell 1 through the return frame 804 until the LED lamp 9 is pushed to the limit position. The link-type pushing structure 8 has the advantages of simple structure, fast response, and smooth movement, and can realize stable linear pushing movement.

[0021] In the use of the embodiment of the present application, during the day, the solar photovoltaic panel 6 absorbs sunlight and converts light energy into electrical energy, which is stored in the built-in electricity storage device. At the same time, the light sensor 7 continuously monitors the ambient light intensity. When it detects sufficient daylight, the device enters the standby state. The LED lamp 9 is hidden inside the hollow cross shell 1 and is in a non-working position. During this process, the light sensor 7 sends the detected light signal to the central controller 13. The central controller 13 controls the C-axis worm and worm gear rotary machine 3 and the A-axis worm and worm gear rotary machine 4 to work according to the detected signal, so as to control the horizontal and vertical rotation angles of the fish skeleton 5 and the solar photovoltaic panel 6, thereby accurately tracking the sun's trajectory and maintaining at a suitable illumination angle. When sunset or night conditions meet the lighting requirements, the lifting power connection assembly 11 is started under the control of the central controller 13. At this time, the lifting power connection assembly 11 enables the gear speed increasing transmission structure 12 and the C-axis worm and worm gear rotary machine 3 to be power-connected. Then, the rotary power of the drive shaft of the C-axis worm and worm gear rotary machine 3 is transmitted to the four link-type pushing structures 8 inside the hollow cross shell 1 through the gear speed increasing transmission structure 12. The link-type pushing structure 8 converts the rotary motion into a linear straight motion, thereby pushing the LED lamp 9 out of the hollow cross shell 1. When the LED lamp 9 is pushed to the limit position, the central controller 13 activates the power supply of the LED lamp 9 to light up the lamp. At this time, the self-locking characteristic of the worm and worm gear transmission is utilized to ensure that the LED lamp 9 can stably maintain the pushed-out state without external force, avoiding misoperation or position deviation. After the LED lamp 9 is pushed out, the electricity storage device connected to the solar photovoltaic panel 6 serves as the main energy supply source to provide power for the LED lamp 9, and the solar photovoltaic panel 6 plays a protective role. When it gets bright, the light sensor 7 detects that the light has returned to the daytime level. The central controller 13 issues an instruction to start the C-axis worm and worm gear rotary machine 3 to supply rotary power and turn off the power supply of the LED lamp 9, so that the LED lamp 9 gradually retracts into the hollow cross shell 1. After the retraction is completed, the lifting power connection assembly 11 resets to disconnect the power connection between the gear speed increasing transmission structure 12 and the C-axis worm and worm gear rotary machine 3. After the device completes the retraction of the lamp, the LED lamp 9 is turned off, and the device enters the standby state, waiting for the next working cycle.

10. A method for the flip of a photovoltaic panel, comprising the photovoltaic panel flip lamp device according to any one of claims 1-9, characterized in that: It includes the following steps: S101: During the day, the solar photovoltaic panel (6) absorbs sunlight and converts light energy into electrical energy, which is stored in the built - in power storage device. The light sensor (7) continuously monitors the ambient light intensity. When it detects sufficient daylight, the device enters the standby state. The LED lamp (9) is hidden inside the hollow cross shell (1) in a non - working position. The light sensor (7) sends the detected light signal into the central controller (13). The central controller (13) controls the C - axis worm and worm gear rotary machine (3) and the A - axis worm and worm gear rotary machine (4) to work according to the detected signal, so as to control the horizontal and vertical rotation angles of the fish - bone frame (5) and the solar photovoltaic panel (6). S102: When the sunset or night conditions meet the lighting requirements, the lifting power connection assembly (11) starts under the control of the central controller (13). At this time, the lifting power connection assembly (11) enables the power combination of the gear speed increasing transmission structure (12) and the C-axis worm and worm gear rotary machine (3). The rotational power of the drive shaft of the C-axis worm and worm gear rotary machine (3) is transmitted to the four link-type pushing structures (8) inside the hollow cross shell (1) through the gear speed increasing transmission structure (12). The link-type pushing structure (8) converts the rotational motion into a linear rectilinear motion, thereby pushing the LED lamp (9) out of the hollow cross shell (1). When the LED lamp (9) is pushed to the limit position, the central controller (13) activates the power supply of the LED lamp (9) to light up the lamp. S103: At dawn, when the light sensor (7) detects that the light has returned to the daytime level, the central controller (13) issues an instruction to start the C-axis worm and worm gear rotary machine (3) to supply rotational power and turn off the power supply of the LED lamp (9), so that the LED lamp (9) is gradually retracted into the hollow cross shell (1). After the retraction is completed, the lifting power connection assembly (11) resets to disconnect the power connection between the gear speed increasing transmission structure (12) and the C-axis worm and worm gear rotary machine (3).
