Technical Field
[0001] This utility model relates to the field of solar street light technology, specifically to an adjustable solar street light. Background Technology
[0002] Solar streetlights are an environmentally friendly and energy-saving streetlight system that uses solar energy to convert into electrical energy to power LED lighting fixtures. Solar streetlights typically consist of solar panels, energy storage batteries, LED lights, controllers, and brackets. Solar streetlights have advantages such as environmental protection and energy saving, automatic light control, independent power supply, convenient maintenance, and long lifespan, which help promote the development of urban lighting towards energy conservation and environmental protection.
[0003] According to patent number CN115899638A, a solar street light is disclosed, including: a lamp, a solar panel, and an angle adjustment component; the angle adjustment component is provided with a horizontal adjustment part and a tilt adjustment part, the tilt adjustment part and the horizontal adjustment part being perpendicular to each other; the angle adjustment component is located between the lamp and the solar panel, and the lamp is rotatably connected to the horizontal adjustment part, and the solar panel is rotatably connected.
[0004] In existing technologies, including the aforementioned patents, the angle of photovoltaic panels on solar streetlights is adjusted to improve light collection. Currently, this adjustment is achieved either manually or by using motors or electric actuators. Motor-driven adjustments allow for remote angle adjustments without requiring manual climbing of the light pole. However, remote electric actuator adjustments lack precise control over the photovoltaic panel's angle, relying solely on visual observation. This results in poor angle collection and wasted energy. Therefore, we propose an adjustable solar streetlight that enables remote adjustment of the photovoltaic panel angle while improving adjustment accuracy and allowing excess energy to be fed back to the grid, preventing energy waste. Utility Model Content
[0005] To address the problems in the existing technology, this utility model provides an adjustable solar street light.
[0006] The technical solution adopted by this utility model to solve its technical problem is an adjustable solar street light, including a light pole, a lamp body for illumination at the arm of the light pole, and a base plate for supporting the light pole at the bottom of the pole. The light pole wall is characterized by a light intensity detection sensor connected to a bracket, and a control device at the pole wall, the control device comprising: The timer, based on the 24-hour time system used to record the sun's deflection position, periodically transmits the 24-hour signal to the controller. The controller sends signals to the actuator to rotate the motor and adjust the brightness of the lamp body light source, based on the 24-hour input signal of the timer and the input signal of the light detection sensor. The actuator controls the operation of the motor and adjusts the intensity of the lamp's brightness based on signals from the controller; An inverter converts direct current (DC) to alternating current (AC) and transmits excess electrical energy to the power grid. It stores power to supply power to other electrical components of the control device, as well as to the motor and lamp body.
[0007] Preferably, the lamp post has a sleeve at the top, and a fixing plate for connecting a motor is welded to the top of the sleeve. The motor is connected to the wall of the fixing plate by bolts, and a gear B is provided at the output shaft end of the motor.
[0008] Preferably, a rotating shaft is rotatably connected to the wall of the fixed plate, a gear A is provided on the shaft wall, and a frame for installing photovoltaic panels is provided at the other end of the rotating shaft, with photovoltaic panels for power generation provided on the frame wall.
[0009] Preferably, the tooth groove of gear A is meshed with the tooth groove of gear B, and when gear B rotates, it drives gear A to rotate, and the rotation of gear A drives the shaft to rotate.
[0010] Preferably, the sleeve and the lamp post are at the same vertical angle, the angle between the sleeve and the fixing plate is less than 90 degrees, and the photovoltaic panel is tilted.
[0011] Preferably, the bottom plate has a through hole in its wall for connecting the externally cast threaded rod.
[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model, through the cooperation of the control device and the light detection sensor, enables the controller in the control device to issue instructions to the actuator. According to the detected light intensity, the actuator controls the opening and closing of the lamp body, and adjusts the brightness of the lamp body light source according to the light intensity, thereby realizing the energy-saving effect of the solar street light. Then, the power storage power can store the electrical energy generated by the photovoltaic panel. The excess electrical energy is converted from DC to AC through the grid-connected inverter and sent to the grid to deal with the excessive electrical energy generated by the photovoltaic panel, thereby solving the problem of energy waste in the background technology and realizing the regulation and use of the photovoltaic panel electrical energy. (2) In this utility model, the timer in the controller sets 24 signals for 24 hours. Before the actuator releases the rotation drive signal to the motor, the timer transmits the 24-hour signal to the controller. The controller releases the signal to the actuator, so the actuator releases the rotation signal to the motor. After the motor drives the gear B at the output shaft end to rotate, the tooth groove of gear B meshes with the tooth groove of gear A, so that gear B drives the rotation of gear A, so that gear A drives the rotating shaft to rotate at the fixed plate. The rotating shaft drives the frame for installing photovoltaic panels to rotate, and the frame drives the photovoltaic panels to rotate. After the controller receives the feedback signal that the actuator has completed its action, the motor stops rotating. Thus, the photovoltaic panels are rotated and adjusted through the 24-hour signal, so that the photovoltaic panels face the sun, improving the power generation efficiency of the photovoltaic panels. This solves the problem of inconvenient adjustment of the photovoltaic panel angle and thus solves the problem of inaccurate control of the light-collecting angle of the photovoltaic panels in the background art.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] As one embodiment of this utility model, such as Figures 1-6 As shown, the adjustable solar street light of this utility model includes a light pole 1, a lamp body 3 for illumination is provided at the support arm of the light pole 1, and a base plate 5 for supporting the light pole 1 is provided at the bottom of the light pole 1. The light pole 1 is characterized by having a light intensity detection sensor 13 connected to the pole wall via a bracket, and a control device 2 provided at the pole wall of the light pole 1. The control device 2 includes: The timer, based on the 24-hour time system used to record the sun's deflection position, periodically transmits the 24-hour signal to the controller. The controller sends signals to the actuator, based on the 24-hour input signal of the timer and the input signal of the light detection sensor 13, to drive the gear B12 to rotate and adjust the brightness of the light source of the lamp body 3. The actuator controls the operation of the motor 9 and adjusts the brightness of the lamp body 3 according to the signal from the controller; An inverter converts direct current (DC) to alternating current (AC) and transmits excess electrical energy to the power grid. The power is stored to supply power to other electrical components of the control device 2, as well as to the motor 9 and the lamp body 3.
[0018] In use, through the cooperation of the controller 2 and the light detection sensor 13, the controller in the controller 2 can issue commands to the actuator. According to the detected light intensity, the actuator controls the opening and closing of the lamp body 3, and adjusts the brightness of the light source of the lamp body 3 according to the light intensity, so as to realize the energy-saving effect of the solar street light. Then, the power generation of the photovoltaic panel 4 is stored through the storage power supply. The excess power is converted from DC to AC through the grid-connected inverter and sent to the grid to cope with the excessive power generated by the photovoltaic panel 4, thereby solving the problem of power waste in the background technology and realizing the regulation and use of the power of the photovoltaic panel 4.
[0019] like Figure 1-6As shown, the top of the lamp post 1 is provided with a sleeve 7. The top of the sleeve 7 is welded with a fixing plate 6 for connecting a motor 9. The wall of the fixing plate 6 is connected to the motor 9 by bolts. The output shaft end of the motor 9 is provided with a gear B12. The wall of the fixing plate 6 is rotatably connected to a rotating shaft 10. The shaft wall of the rotating shaft 10 is provided with a gear A11. The other end of the rotating shaft 10 is provided with a frame 8 for installing photovoltaic panels 4. The frame wall of the frame 8 is provided with photovoltaic panels 4 for generating electricity. The tooth groove of the gear A11 meshes with the tooth groove of the gear B12. When the gear B12 rotates, it drives the gear A11 to rotate. The rotation of the gear A11 drives the rotating shaft 10 to rotate.
[0020] In use, the timer in the controller 2 sets 24 signals for 24 hours. Before the actuator releases the rotation drive signal to the motor 9, the timer transmits the 24-hour signal to the controller. The controller then releases a signal to the actuator, which in turn releases a rotation signal to the motor 9. The motor 9 drives the gear B12 at its output shaft to rotate, and the tooth groove of gear B12 meshes with the tooth groove of gear A11. Thus, gear B12 drives the rotation of gear A11, which in turn drives the rotating shaft 10 to rotate at the fixed plate 6. The rotating shaft 10 drives the frame 8 used to install the photovoltaic panel 4 to rotate, and the frame 8 drives the photovoltaic panel 4 to rotate. After the controller receives the feedback signal that the actuator has completed its action, the motor 9 stops rotating. Thus, the rotation of the photovoltaic panel 4 is adjusted through the 24-hour signal, so that the photovoltaic panel 4 faces the sun, improving the power generation efficiency of the photovoltaic panel 4. This addresses the problem of inconvenient angle adjustment of the photovoltaic panel 4 and solves the problem of inaccurate control of the light-receiving angle of the photovoltaic panel 4 in the background technology.
[0021] like Figure 1-2 As shown, the sleeve 7 and the lamp post 1 are at the same vertical angle, the angle between the sleeve 7 and the fixing plate 6 is less than 90 degrees, and the photovoltaic panel 4 is tilted.
[0022] When in use, after the sleeve 7 and the lamp post 1 are at the same vertical angle, there is an angle between the sleeve 7 and the fixing plate 6, so that the photovoltaic panel 4 is in an inclined state. The inclined photovoltaic panel 4 is less likely to retain rainwater and dust, and is more likely to be directly exposed to sunlight, thus improving power generation efficiency.
[0023] like Figure 1 As shown, the bottom plate 5 has a through hole on its wall for connecting the externally cast threaded rod.
[0024] When in use, after the externally cast screw is inserted into the through hole, the external nut is connected to the screw, so that the nut presses against the base plate 5 to fix the lamp post 1.
[0025] In use, this invention, through the cooperation of the controller 2 and the light detection sensor 13, enables the controller in the controller 2 to issue commands to the actuator. Based on the detected light intensity, the actuator controls the opening and closing of the lamp body 3, and adjusts the brightness of the light source of the lamp body 3 according to the light intensity, achieving the energy-saving effect of the solar street light. Furthermore, the electrical energy generated by the photovoltaic panel 4 is stored through a storage power source. Excess electrical energy is converted from DC to AC by a grid-connected inverter and transmitted to the power grid to address the excessive electrical energy generated by the photovoltaic panel 4, thus solving the problem of energy waste in the prior art and realizing the regulated use of the electrical energy from the photovoltaic panel 4. The timer in the controller 2 sets 24 signals for 24 hours. Before the actuator releases the rotation drive signal to the motor 9, the timer sets 24 signals for 24 hours. The time signal is transmitted to the controller, which releases a signal to the actuator, which in turn releases a rotation signal to the motor 9. The motor 9 drives the gear B12 at the output shaft to rotate, and the tooth groove of gear B12 meshes with the tooth groove of gear A11. Thus, gear B12 drives the rotation of gear A11, which in turn drives the rotating shaft 10 to rotate at the fixed plate 6. The rotating shaft 10 drives the frame 8 used to install the photovoltaic panel 4 to rotate, and the frame 8 drives the photovoltaic panel 4 to rotate. After the controller receives the feedback signal that the actuator has completed its action, the motor 9 stops rotating. Thus, the rotation of the photovoltaic panel 4 is adjusted through the 24-hour signal, so that the photovoltaic panel 4 faces the sun, improving the power generation efficiency of the photovoltaic panel 4. This addresses the problem of inconvenient angle adjustment of the photovoltaic panel 4 and solves the problem of not being able to accurately control the light-receiving angle of the photovoltaic panel 4 in the background technology.
