Description

Technical Field

[0001] The present invention relates to the technical field of solar street lamps, and in particular to a lamp device with a flippable photovoltaic panel and a method thereof. Background Art

[0002] The outdoor lighting with a reversible photovoltaic panel is an environmentally friendly device that combines solar energy utilization and efficient lighting. It is widely used in outdoor places such as courtyards, parks and roads. Its main functions are energy conservation and emission reduction, improved safety, easy installation and intelligent control. By utilizing the solar photovoltaic panel to absorb sunlight during the day, it converts it into electrical energy and stores it in the built-in battery. At night or when there is insufficient light, the stored electrical energy drives the LED lamp to provide lighting. The reversible design of the panel allows users to adjust the angle according to the position of the sun or actual needs, maximizing light energy absorption and improving lighting efficiency. Its structure includes a high-efficiency and weather-resistant photovoltaic panel, an adjustable angle rotating bracket, LED lamps, a power storage system and an intelligent control circuit to ensure the stability and long-term use of the equipment. During operation, the photovoltaic panel absorbs solar energy during the day, converts it into electrical energy and stores it in the battery; at night or when the environment is dark, the sensor detects the brightness, automatically turns on the lamp, and uses the stored electrical energy to continuously provide lighting;

[0003] For example, a solar street light with a flippable photovoltaic panel disclosed in the authorization announcement number CN119436014B includes a street light pole and a lamp body installed on the street light pole. A sliding sleeve is provided on the outer side of the street light pole, and a hexagonal frame is installed on the sliding sleeve. A receiving groove is provided on the side of the hexagonal frame, and a flip plate is provided in the receiving groove. A photovoltaic panel is provided on one side of the flip plate, and a billboard is provided on the other side of the flip plate. A plurality of fixed plates are provided on the top of the hexagonal frame. By driving the flip plate to rotate to an inclined state, a pump draws water in the receiving chamber to the nozzle for spraying; a rotating driving member drives the worm to rotate , driving the hexagonal frame to rotate around the sliding sleeve, driving the flip plate to rotate around the axis of the sliding sleeve, and at the same time the flip plate can also rotate on its own, driving the blower nozzle to spray water towards the photovoltaic panels on different flip plates, so as to achieve the purpose of cleaning the photovoltaic panels. However, the above technical solution also adopts a structural form in which the lamp is on top and the photovoltaic panel is on the bottom. It fails to fully utilize the protective characteristics of the large width of the photovoltaic panel, resulting in the lamp being directly exposed to the external environment for a long time and being directly attacked by natural factors such as rain, dust, bird droppings, and wind and sand. At this time, the exposed lamp is prone to problems such as leakage, corrosion, and aging, which seriously affect the lighting effect and service life. Summary of the Invention

[0015] Preferably, the guide sleeve, slide rod, connecting plate, circular frame and swing arm are all made of hard plastic materials.

[0016] The present invention also provides a method for flipping a photovoltaic panel, such as the above-mentioned flippable photovoltaic panel lamp device, comprising the following steps:

[0017] S101: During the day, the solar photovoltaic panel absorbs sunlight and converts light energy into electrical energy, which is stored in the built-in power storage device. The light sensor continuously monitors the ambient light intensity. When it detects that there is sufficient light during the day, the device enters the standby state, and the LED light is hidden in the hollow cross shell and is in the non-working position. The light sensor sends the detected light signal to the central controller. The central controller controls the C-axis worm gear rotary machine and the A-axis worm gear rotary machine according to the detected signal to control the horizontal and vertical rotation angles of the fish frame and the solar photovoltaic panel.

[0018] S102: When sunset or nighttime conditions meet the lighting requirements, the lifting power connection assembly is activated under the control of the central controller. At this time, the lifting power connection assembly enables the gear speed-increasing transmission structure and the C-axis worm gear rotary machine to combine power. The rotational power of the drive shaft of the C-axis worm gear rotary machine is transmitted to the four connecting rod push structures inside the hollow cross housing through the gear speed-increasing transmission structure. The connecting rod push structures convert the rotational motion into linear motion, thereby pushing the LED lamp out of the hollow cross housing. When the LED lamp is pushed to the extreme position, the central controller activates the power supply of the LED lamp to light the lamp;

[0019] S103: At daybreak, the light sensor detects that the light has returned to the daytime level, and the central controller issues a command to start the C-axis worm gear rotary machine to supply rotation power and turn off the power 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 increase transmission structure and the C-axis worm gear rotary machine.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the photovoltaic panel flip lamp device and method thereof are provided with a hollow cross shell, a column head, a C-axis worm gear rotary machine, an A-axis worm gear rotary machine, a solar photovoltaic panel, a light sensor, an LED lamp and a lifting power connection assembly, etc., which 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 installed with a C-axis worm gear rotary machine and an A-axis worm gear rotary machine for controlling the rotation of the solar photovoltaic panel, so as to adjust to the optimal light receiving angle under the detection of the light sensor. When the LED lamp is not working 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 increase transmission structure and the C-axis worm gear rotary machine to be power-coupled, so that each connecting rod push structure pushes the LED lamp out of the hollow cross shell to light up normally, thereby achieving the purpose of hiding the LED lamp for protection during the day and pushing it out at night and being protected by the solar photovoltaic panel.

[0021] During the day, all LED lights are retracted into the hollow cross shell, avoiding the direct impact of sunlight, rain, dust and other environmental factors on the lamps, greatly reducing the risk of corrosion and aging of the lamps, thereby extending the service life of the lamps. In the hidden state, the LED lights are not affected by external mechanical shock or pollution, reducing maintenance frequency and maintenance costs. When sunset or night conditions meet the lighting requirements, the lifting power connection assembly starts, driving the gear speed increase transmission structure and the connecting rod push structure to receive the rotational power from the C-axis worm gear rotary machine, pushing the LED lights out of the hollow cross shell and lighting them normally. This process realizes automated operation, avoiding the inconvenience and error of manual operation, ensuring that the lamps light up in time when needed, and ensuring the continuity and stability of night lighting. At the same time, the solar photovoltaic panel is located above the LED lamp at night. Its sturdy structure can also protect the LED lamp from direct exposure to the environment, reducing the invasion of natural factors such as rain, dust, bird droppings, and wind and sand, and extending the service life of outdoor lamps from the root.

[0022] Secondly, the worm gear transmission structure has good self-locking performance, which can ensure the stability of the LED light in the hidden and extended states, and avoid malfunction due to vibration or external force. The spatial arrangement of the C-axis and A-axis worm gear rotation mechanisms enables the photovoltaic panel to accurately track the trajectory of the sun, and the unique self-locking characteristics ensure that the positioning can be maintained without continuous energy consumption after the angle is adjusted, which not only improves the tracking accuracy but also reduces the system power consumption; finally, the daytime transmission system of the C-axis worm gear rotary machine and the A-axis worm gear 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 increase mechanism and the worm gear, the power is efficiently converted into the linear displacement required for the LED to be launched. The connecting rod push structure converts the rotational motion into precise linear motion, ensuring the synchronous and smooth extension of multiple groups of LEDs. This time-sharing multiplexing transmission path design avoids the addition of independent drive devices, which not only simplifies the mechanical structure but also ensures the reliability of the action.

[0036] A C-axis worm gear rotary machine 3 is installed at the center position of the top of the hollow cross housing 1, an A-axis worm gear rotary machine 4 is installed at the upper end of the drive shaft of the C-axis worm gear rotary machine 3, an upper spline shaft 10 is installed at the lower end of the drive shaft of the C-axis worm gear rotary machine 3, and fish skeletons 5 are installed on the left and right ends of the drive shaft of the A-axis worm gear rotary machine 4, and a solar photovoltaic panel 6 is installed on the upper surface of the fish skeleton 5. The C-axis worm gear rotary machine 3 and the A-axis worm gear rotary machine 4 realize the horizontal and vertical angle adjustment of the fish skeleton 5 and the solar photovoltaic panel 6. Both have high torque transmission and self-locking functions to ensure the stability of the rotation position;

[0037] The hollow cross shell 1 serves as the outer shell 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 light 9;

[0038] A light sensor 7 is installed on one side of the top of the fish skeleton 5, and a central controller 13 is installed on the inner wall of one side of the column head 2. The output end of the central controller 13 is electrically connected to the input end of the C-axis worm gear rotary machine 3 and the A-axis worm gear rotary machine 4, respectively, and the input end of the central controller 13 is electrically connected to the output end of the light sensor 7;

[0039] A connecting rod type sliding structure 8, four connecting rod type sliding structures 8 are installed in a circular and equidistant manner inside the hollow cross shell 1, and an LED light 9 is installed on the movable end of the connecting rod type sliding structure 8. A gear speed-increasing transmission structure 12 for power connection is installed between the four connecting rod type sliding structures 8. A lifting power connection assembly 11 for power connection between the gear speed-increasing transmission structure 12 and the upper spline shaft 10 is installed inside the column head 2. The input end of the lifting power connection assembly 11 is electrically connected to the output end of the central controller 13;

[0040] A photovoltaic panel reversible method of this embodiment, such as the above-mentioned photovoltaic panel reversible lamp device, includes the following steps:

[0041] 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 that there is sufficient light during the day, the device enters a standby state, and the LED light 9 is hidden in the hollow cross shell 1 and is in a non-working position. The light sensor 7 sends the detected light signal to the central controller 13. The central controller 13 controls the C-axis worm gear rotary machine 3 and the A-axis worm gear rotary machine 4 to operate 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;

[0042] S102: When sunset or nighttime conditions meet the lighting requirement, 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 gear rotary machine 3 to combine power. The driving shaft rotational power of the C-axis worm gear rotary machine 3 is transmitted to the four connecting rod push structures 8 inside the hollow cross housing 1 through the gear speed-increasing transmission structure 12. The connecting rod push structures 8 convert the rotational motion into linear motion, thereby pushing the LED lamp 9 out of the hollow cross housing 1. When the LED lamp 9 is pushed to the extreme position, the central controller 13 activates the power supply of the LED lamp 9 to light the lamp;

[0043] S103: At daybreak, the light sensor 7 detects that the light has returned to the daytime level, and the central controller 13 issues a command to start the C-axis 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 is reset to disconnect the power connection between the gear speed increase transmission structure 12 and the C-axis worm gear rotary machine 3.

[0044] Example 2, based on Example 1, Figure 7 and Figure 8 The C-axis worm gear rotary machine 3 includes a cylindrical casing 301 fixed at the top center of the hollow cross casing 1, a vertical shaft rotatably installed at the vertical center position inside the cylindrical casing 301, and a stepper motor 303 installed on the outer wall of one side of the cylindrical casing 301. One end of the driving shaft of the stepper motor 303 extends to the inside of the cylindrical casing 301 and is installed with a worm. One end of the surface of the vertical shaft is installed with a worm wheel that meshes with the worm. A turntable 302 is fixed to the top of the vertical shaft. The bottom end is fixedly connected to the top of the upper spline shaft 10, the A-axis worm gear rotary machine 4 is installed on the upper surface of the turntable 302, and the input end of the stepper motor 303 is electrically connected to the output end of the central controller 13. When the C-axis worm gear rotary machine 3 is working, the driving shaft of the stepper motor 303 drives the upper spline shaft 10 and the turntable 302 to rotate through the worm and the worm wheel, and drives the A-axis worm gear rotary machine 4, the fish skeleton 5, and the solar photovoltaic panel 6 to rotate horizontally through the turntable 302;

[0045] 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 passes through 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 make the gear speed increase transmission structure 12 and the upper spline shaft 10 power combined, the central controller 13 sends a working signal to the electric push rod 1102, so that the electric push rod 1102 pushes the lower spline shaft 1103 to move 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, so that the C-axis worm gear rotary machine 3 can transmit rotational power to the gear speed increase transmission structure 12 when working.

[0046] Example 3, based on Example 2, Figure 9 and Figure 10 The gear speed increasing transmission structure 12 includes a hollow shaft sleeve 1201 fixed at the bottom center of the hollow cross shell 1, a middle shaft 1202 rotatably installed inside the hollow shaft sleeve 1201, and a center toothed 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. A straight-mouth notch is provided on one side of the surface of the middle shaft 1202, and a straight-mouth notch is integrally formed on one end of the surface of the lower spline shaft 1103. The raised head outside the notch, after the lower spline shaft 1103 moves up and completes docking with the upper spline shaft 10, the C-axis worm gear 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 are matched with keyways, the middle shaft 1202 and the center gear plate 1203 rotate downward together under the drive of the lower spline shaft 1103, thereby driving the four driven gears 1204 to rotate synchronously through the center gear plate 1203, thereby driving the connecting rod type push structure 8 to start action;

[0047] The connecting rod type pushing structure 8 includes a driven shaft 801 rotatably mounted on one side of the interior of the hollow cross housing 1, a swing arm 802 fixed to one end of the surface of the driven shaft 801, and a connecting rod arm 803 slidably mounted on one side of the interior of the hollow cross housing 1. A circular frame 804 is hingedly mounted between the outer wall of one side of the connecting rod arm 803 and the end of the swing arm 802. The LED lamp 9 is mounted on the bottom end of the connecting rod arm 803. A driven gear 1204 is fixed to one end of the surface of the driven shaft 801 and meshes with the central gear disc 1203. The outer walls of the hollow cross housing 1 are all provided with hollow portions for the LED lamp 9 to pass through.

[0048] The connecting rod arm 803 includes two guide sleeves fixed on the inner wall of one side of the hollow cross shell 1, a sliding rod slidably installed inside the guide sleeve, and a connecting plate fixed at both ends of the two sliding rods. The outer wall of one side of one connecting plate is hinged to one end of the circular frame 804. The guide sleeve, sliding rod, connecting plate, circular frame 804, and swing arm 802 are all made of hard plastic components. 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 connecting rod arm 803 and the LED lamp 9 are gradually moved out of the hollow cross shell 1 through the circular frame 804 until the LED lamp 9 is pushed to the extreme position. The connecting rod push structure 8 has the advantages of simple structure, fast response, and smooth movement, and can achieve stable linear push motion.

[0049] When the embodiment of the present application is in use, the solar photovoltaic panel 6 absorbs sunlight during the day and converts light energy into electrical energy and stores it in the built-in power storage device. At the same time, the light sensor 7 continuously monitors the ambient light intensity. When it detects that there is sufficient light during the day, the device enters the standby state. The LED light 9 is hidden in 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, and the central controller 13 controls the C-axis worm gear rotary machine 3 and the A-axis worm gear rotary machine 4 to work according to the detected signal. , to control the horizontal and vertical rotation angles of the fish frame 5 and the solar photovoltaic panel 6, so as to accurately track the trajectory of the sun and maintain the appropriate lighting angle; when the 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 gear rotary machine 3 to combine power, and the driving shaft rotation power of the C-axis worm gear rotary machine 3 is transmitted to the four connecting rod pushers inside the hollow cross shell 1 through the gear speed-increasing transmission structure 12. On the structure 8, the connecting rod push structure 8 converts the rotational motion into linear motion, thereby pushing the LED lamp 9 out of the hollow cross shell 1. When the LED lamp 9 is pushed out to the limit position, the central controller 13 activates the power supply of the LED lamp 9 and lights the lamp. At this time, the self-locking characteristics of the worm gear transmission are used to ensure that the LED lamp 9 can stably maintain the pushed-out state when there is no external force, avoiding malfunction or position displacement. After the LED lamp 9 is pushed out, the power storage device connected to the solar photovoltaic panel 6 serves as the main energy supply source to provide power to the LED lamp 9, and the solar The solar photovoltaic panel 6 plays a protective role; at dawn, the light sensor 7 detects that the light has returned to the daytime level, and the central controller 13 issues a command to start the C-axis worm gear rotary machine 3 to supply rotational power and turn off the power of the LED lamp 9, so that the LED lamp 9 is gradually retracted into the hollow cross shell 1. After the collection is completed, the lifting power connection assembly 11 is reset to disconnect the power connection between the gear speed increase transmission structure 12 and the C-axis 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.
