Technical Field
[0001] This utility model relates to the field of lighting lighthouse technology, specifically a solar-powered mobile lighting lighthouse. Background Technology
[0002] In the field of outdoor mobile lighting, solar-powered mobile lighting towers are widely used in construction sites, emergency rescue, field operations, temporary events and other scenarios due to their advantages of being green and energy-saving and requiring no external power source.
[0003] However, traditional mobile lighting towers mostly use solar panels with fixed angles. The sun's altitude and azimuth angles change constantly throughout the day, and fixed-angle solar panels can only receive near-vertical sunlight for a few hours around noon. In the early morning, evening, or during different seasons, the angle between the sunlight's incident angle and the solar panel surface is too large, causing a significant decrease in light absorption efficiency. Therefore, a solar-powered mobile lighting tower is needed. Utility Model Content
[0004] The purpose of this invention is to provide a solar-powered mobile lighting tower, which uses an adjustable component to drive the solar panel to rotate and adjust the angle so that the solar panel can remain nearly perpendicular to the sun, thereby solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A solar-powered mobile lighting tower includes a movable base, a fixed box mounted on the upper part of the base, two sets of solar panels symmetrically mounted on both sides of the fixed box, and an adjustment component for driving the solar panels to rotate mounted in the middle of the fixed box.
[0007] The adjustment assembly includes a lead screw that runs through the middle of the fixed box. A servo motor that drives the active cone wheel to rotate is installed at the lower part of the lead screw. A driven cone wheel that meshes with the active cone wheel is installed at the middle part of the lead screw. Connecting blocks that connect to the solar panel are installed at both ends of the lead screw on both sides of the fixed box.
[0008] Preferably, the sidewall of the solar panel is fitted with a fixing member, which is rotatably connected to the connecting block via a rotating shaft.
[0009] Preferably, a stepper motor for driving the solar panel to rotate is keyed to the end of the rotating shaft, and the rotating shaft is keyed to a fixing component.
[0010] Preferably, a support plate is installed inside the fixed box, and the servo motor is installed on the upper part of the support plate.
[0011] Preferably, a power supply is installed inside the fixed box at the lower part of the support plate, and both sets of solar panels are electrically connected to the power supply through a photovoltaic charging controller.
[0012] Preferably, a support column is installed on the upper part of the base on the side of the fixed box, and a movable column for connecting a lighting lamp is movably installed on the upper part of the support column.
[0013] Preferably, the support column has a cavity in the middle, and an electric push rod for driving the movable column to move is installed inside the cavity. The output end of the electric push rod is connected to the bottom of the movable column.
[0014] Preferably, a support plate is installed on the upper part of the movable column, and several sets of lighting lamps are all arranged on the upper surface of the support plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] By setting up an adjustment assembly consisting of a servo motor, lead screw, and conical wheel assembly, the solar panels on both sides can be driven to adjust their deflection angle synchronously, achieving active tracking of the sun's azimuth and elevation angles. This increases the effective light-receiving time and vertical light-receiving rate, solving the problem of light energy loss caused by the incident light deviating from the optimal angle in traditional fixed solar panels.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides: a solar-powered mobile lighting tower, such as... Figures 1-5 As shown, the lighthouse includes a movable base 1, a fixed box 2 mounted on top of the base 1, two sets of solar panels 3 symmetrically mounted on both sides of the fixed box 2, and an adjustment assembly 4 for driving the rotation of the solar panels 3 mounted in the middle of the fixed box 2. The movable base 1 provides a movable mounting platform for the lighthouse, facilitating its relocation to different locations. The fixed box 2, mounted on top of the movable base 1, provides installation space and protection for important components such as the solar panels 3 and the adjustment assembly 4. The two sets of solar panels 3 are symmetrically mounted on both sides of the fixed box 2, converting solar energy into electrical energy through the photovoltaic effect. The adjustment assembly 4, mounted in the middle of the fixed box 2, is used to drive the rotation of the solar panels 3 to adjust their orientation and angle.
[0025] The adjustment assembly 4 includes a lead screw 41 that runs through the middle of the fixed box 2. A servo motor 42 is installed at the lower part of the lead screw 41 to drive the active conical wheel 43 to rotate. A driven conical wheel 44 that meshes with the active conical wheel 43 is installed at the middle part of the lead screw 41. Connecting blocks 45 that connect to the solar panel 3 are installed at both ends of the lead screw 41 on both sides of the fixed box 2. When the servo motor 42 is powered on, it outputs power to drive the active conical wheel 43 to rotate. The active conical wheel 43 meshes with the driven conical wheel 44, transmitting power to the lead screw 41, causing the lead screw 41 to rotate around its own axis. The connecting blocks 45 at both ends of the lead screw 41 are connected to the solar panel 3. As the lead screw 41 rotates, the connecting blocks 45 move axially on the lead screw 41, thereby causing the solar panel 3 to rotate synchronously. This achieves the adjustment of the azimuth angle of the solar panel 3, enabling the solar panel 3 to rotate according to the change of the sun's azimuth, always maintaining a better incident angle with the sunlight, increasing the effective light reception time of the solar panel 3, and improving the light energy absorption efficiency.
[0026] The servo motor 42 is a DC servo motor with a rated power of 50-100W, a rated speed of 3000-5000rpm, and a torque of 0.15-0.3N·m, equipped with a 1000-line encoder. This power range can meet the load requirements of the lead screw 41 driving the solar panels 3 on both sides to rotate synchronously, avoiding adjustment jamming due to insufficient power; the speed of 3000-5000rpm, combined with the deceleration of the conical wheel group, can achieve a slow deflection of 0.5-2° per minute for the solar panel 3, which is consistent with the rate of change of the solar azimuth angle; the torque of 0.15-0.3N·m can ensure stable driving under conditions such as strong winds; the 1000-line encoder can provide an angular resolution of 0.36°, ensuring the accuracy of azimuth angle adjustment, so that the solar panel 3 is always aligned with the sun, improving the light energy absorption efficiency.
[0027] Preferably, a fixing member 46 is installed on the side wall of the solar panel 3, and the fixing member 46 is rotatably connected to the connecting block 45 via a rotating shaft 47. The fixing member 46 installed on the side wall of the solar panel 3 is used to connect the solar panel 3 to the rotating shaft 47, allowing the solar panel 3 to rotate around the rotating shaft 47. The rotating shaft 47 is connected to the fixing member 46 and the stepper motor 48 via a key connection, which serves to transmit torque. The stepper motor 48, as a driving component, outputs precise rotational power after being powered on, driving the fixing member 46 and the solar panel 3 to rotate around the rotating shaft 47, facilitating the storage of the solar panel 3 and thus reducing the overall size of the device.
[0028] Preferably, a stepper motor 48 for driving the solar panel 3 to rotate is keyed to the end of the rotating shaft 47, and the rotating shaft 47 is keyed to the fixing member 46. When the solar panel 3 needs to be adjusted, the stepper motor 48 starts, driving the solar panel 3 to rotate around the fixing member 46 via the rotating shaft 47, thereby changing the angle between the solar panel 3 and the horizontal plane. Combined with the adjustment component 4 for adjusting the azimuth angle, the solar panel 3 can actively track the changes in the azimuth and altitude angles of the sun in two-dimensional space, further increasing the vertical light absorption rate of the solar panel 3, reducing light energy loss caused by the incident light deviating from the optimal angle, and significantly improving the light energy absorption efficiency and power generation capacity.
[0029] Stepper motor 48 is a two-phase hybrid stepper motor with a step angle of 1.8° (down to 0.09° after microstepping), a holding torque of 0.5-1 N·m, and a rated current of 1.5-2 A. The 1.8° step angle, combined with 16 microstepping, achieves an adjustment accuracy of 0.09°, meeting the needs of subtle changes in the solar altitude angle at different times. The 0.5-1 N·m holding torque ensures that the solar panel 3 maintains its current angle stably after adjustment. The 1.5-2 A rated current matches the output capacity of the power supply 6, ensuring power while avoiding excessive energy consumption.
[0030] Furthermore, a support plate 5 is installed inside the fixed housing 2, and the servo motor 42 is mounted on the upper part of the support plate 5. The support plate 5 inside the fixed housing 2 provides a stable mounting platform for the servo motor 42, ensuring that the servo motor 42 remains stable during operation and avoiding the impact of vibration and other factors on its driving performance. The servo motor 42 is mounted on the upper part of the support plate 5 and connected to the support plate 5 by bolts or other fixing methods, reliably transmitting power to the adjustment component 4 and ensuring that the adjustment component 4 can work stably. This structural design makes reasonable use of the internal space of the fixed housing 2, making the layout of each component compact and enhancing the stability and reliability of the entire adjustment system.
[0031] Furthermore, a power supply 6 is installed inside the mounting box 2, located below the support plate 5. Both sets of solar panels 3 are electrically connected to the power supply 6 via a photovoltaic charging controller. The power supply 6 inside the mounting box 2 stores the electrical energy converted from the solar panels 3, providing power to the lighthouse's lighting system and various drive components. The photovoltaic charging controller converts the unstable electrical energy generated by the solar panels 3 into stable electrical energy and charges the power supply 6, while preventing overcharging or over-discharging. When the lighthouse needs to operate, the power supply 6 provides power to components such as the servo motor 42, stepper motor 48, electric push rod 10, and lighting lamp 12, ensuring the normal operation of each component. This design achieves energy self-sufficiency for the lighthouse, extends the lighting duration, and enhances the lighthouse's adaptability in outdoor environments without external power.
[0032] Power supply 6 uses a 12V / 24V DC lithium battery pack with a capacity of 100-200Ah, supporting 500-1000W instantaneous discharge and featuring overcharge, over-discharge, and short-circuit protection. The 12V / 24V voltage is compatible with the operating voltages of components such as the servo motor 42, stepper motor 48, and electric actuator 10, eliminating the need for additional transformers. The 100-200Ah capacity can store one day's worth of electricity generated by the solar panel 3 (assuming an average daily power generation of 5-10kWh), meeting the continuous lighting and equipment operation needs of the lighthouse. The 500-1000W instantaneous discharge capability supports the simultaneous operation of multiple lighting lamps 12. Multiple protection functions prevent overcharging risks during solar panel 3 charging and over-discharge and short-circuit problems during equipment operation, extending battery life and ensuring the stability of the lighthouse's energy supply in outdoor environments.
[0033] It is worth noting that a support column 7 is installed on the upper part of the base 1, located on the side of the fixed box 2. A movable column 8, connecting the lighting lamp 12, is movably installed on the upper part of the support column 7. The support column 7 on the upper part of the base 1 provides a vertical track for the movable column 8. The movable column 8 is movably installed on the upper part of the support column 7 to support the lighting lamp 12. Driven by the electric push rod 10, it moves up and down along the support column 7 to adjust the height of the lighting lamp 12. This allows the lighting lamp 12 to be adjusted according to actual lighting needs, meeting the lighting requirements in different scenarios and improving the practicality of the lighthouse.
[0034] Specifically, a cavity 9 is provided in the middle of the support column 7. An electric push rod 10, which drives the movable column 8, is installed inside the cavity 9. The output end of the electric push rod 10 is connected to the bottom of the movable column 8. The cavity 9 provides installation space for the electric push rod 10, allowing it to be hidden inside the support column 7, thus protecting it from external environmental influences. The electric push rod 10 is installed inside the cavity 9, and its output end is connected to the bottom of the movable column 8. When powered on, the internal motor and transmission mechanism convert the rotational motion of the motor into linear reciprocating motion at the output end, thereby driving the movable column 8 to move up and down. This ensures that the lighting lamp 12 accurately reaches the required height, meeting the height requirements of different lighting scenarios and improving the intelligence and ease of use of the lighthouse.
[0035] More specifically, a support plate 11 is installed on the upper part of the movable column 8, and several sets of lighting lamps 12 are all set on the upper surface of the support plate 11. The support plate 11 on the upper part of the movable column 8 provides a stable mounting platform for the several sets of lighting lamps 12. The several sets of lighting lamps 12 are set on the upper surface of the support plate 11 and emit light after being powered on, realizing the lighting function. The reasonable distribution of the several sets of lighting lamps 12 on the support plate 11 can expand the lighting range, improve the lighting brightness, and meet the lighting needs of different sites. At the same time, the structural strength and stability of the support plate 11 ensures that the lighting lamps 12 will not loosen or be damaged due to vibration or other factors during operation, thus enhancing the reliability of the lighthouse lighting system.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
