Description
Technical Field
[0001] This invention belongs to the field of new energy lighting technology, specifically relating to a photovoltaic power generation new energy outdoor lighting device. Background Technology
[0002] Photovoltaic streetlights are independent power supply lighting facilities with solar photovoltaic power generation systems as their core. They convert light energy into electrical energy through solar panels and store it in batteries. At night, the controller supplies power to the lights. This equipment has the characteristics of zero fossil energy consumption and flexible installation, and is suitable for rural areas with poor grid coverage and urban landscape lighting.
[0003] In existing systems, photovoltaic panels and lighting fixtures are mostly fixed installations. During the day, when the photovoltaic panels are working, the lighting fixtures are exposed, easily attracting birds and leaving droppings. This not only affects the cleanliness of the lighting fixtures and the nighttime illumination effect but also requires frequent manual cleaning. In the evening and at night, the photovoltaic panels are still exposed, and birds easily perch on their surfaces. The accumulation of bird droppings blocks sunlight, reducing the photovoltaic conversion efficiency the next day. Furthermore, in outdoor environments, dust, fallen leaves, and other debris easily accumulate on the surface of the photovoltaic panels. If not cleaned in time, this will significantly reduce the photoelectric conversion efficiency. Relying on regular manual wiping results in high maintenance costs, especially in remote outdoor areas where this is difficult to achieve. At the same time, the existing bird-repelling measures of outdoor lighting installations are significantly inadequate, mostly using simple reflectors and static windmills. Birds can easily adapt, resulting in poor long-term bird-repelling effects. Some electric bird-repelling devices require continuous power consumption, increasing the burden on the photovoltaic system. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a new energy outdoor lighting device for photovoltaic power generation.
[0005] The technical solution adopted to solve the above-mentioned technical problems is: a new energy outdoor lighting device for photovoltaic power generation, including a lamp post and a base. The top of both sides of the base are respectively hinged with a lighting lamp and a mounting frame. A photovoltaic panel is installed on the surface of the mounting frame. The interior of the base is provided with a retraction mechanism for adjusting the angle of the lighting lamp and the mounting frame. Both ends of the mounting frame are provided with a dust cleaning mechanism for cleaning the dust on the surface of the photovoltaic panel. The top of the base is provided with a bird deterrent mechanism for deterring birds.
[0006] Furthermore, the retraction mechanism includes a first rotating shaft, of which two pairs are provided, and the two pairs of first rotating shafts are respectively located at the inner top and inner bottom of the bottom compartment. On the same side, two sets of first rotating shafts are equipped with lead screws through universal joints. The two sets of lead screws are inclined. The outer side of the lead screw is provided with an internal threaded ring. The two sets of internal threaded rings are respectively located at the top and bottom of the outer side of the lead screw. The outer side of the internal threaded ring is hinged with a hinge rod, and the ends of the two sets of hinge rods away from the internal threaded rings are respectively hinged to the inner side of the lighting lamp and the mounting bracket. The outer side of the bottom compartment is symmetrically provided with strip-shaped through slots that cooperate with the hinge rods. The inner top of the bottom compartment is provided with a drive device for driving the two sets of lead screws to rotate.
[0007] Through the above technical solution, the drive device drives the lead screw to rotate, and the internal threaded ring moves along the lead screw axis. Through the hinge rod, it pushes the lighting lamp and the mounting bracket to rotate around the hinge axis. When the lead screw rotates counterclockwise, the lighting lamp unfolds and the photovoltaic panel folds up. When it rotates clockwise, the lighting lamp folds up and the photovoltaic panel unfolds, realizing the synchronous counterclockwise unfolding and retraction of the photovoltaic panel and the lighting lamp. During the day, the photovoltaic panel unfolds to receive sunlight while the lighting lamp folds up to prevent bird droppings. In the evening, the photovoltaic panel folds up and the lighting lamp unfolds to provide illumination, preventing birds from landing on the photovoltaic panel. At the same time, the folding up of the photovoltaic panel can reduce the risk of damage in hail weather and improve the durability of the equipment.
[0008] Furthermore, the drive device includes a servo motor located at the top of the bottom compartment, the output shaft of the servo motor is equipped with a drive gear, and the outer sides of the top pair of first rotating shafts are each equipped with a driven gear that meshes with the drive gear.
[0009] Through the above technical solution, the servo motor drives the active gear to rotate, and through the meshing transmission with the driven gear, drives the two sets of lead screws to rotate synchronously, realizing precise control of the retraction and extension actions. The servo motor provides stable power, and the gear transmission ensures the synchronization of the two sets of lead screws, ensuring the precise retraction and extension angle of the photovoltaic panel and the lighting lamp, adapting to the needs of day and night switching, and improving the degree of automation.
[0010] Furthermore, the dust removal mechanism includes a rotating rod positioned horizontally in the middle of the bottom chamber. Both ends of the rotating rod extend to the outside of the bottom chamber and are symmetrically equipped with connecting rods. Both ends of the mounting frame are provided with slidable sliding seats, and cleaning brushes are installed on the outer sides of the two sets of connecting rods. The end of the connecting rod away from the rotating rod is hinged to an adjacent set of sliding seats. A fixing ring is installed in the middle of the outer side of the rotating rod. Torsion springs are symmetrically sleeved at both ends of the outer side of the rotating rod, and the two ends of the torsion springs are fixedly connected to the fixing ring and the inner wall of the bottom chamber, respectively.
[0011] With the above technical solution, when the photovoltaic panel is folded up, the mounting frame rotates and drives the sliding seat to move. With the torque of the torsion spring, the rotating rod drives the connecting rod to rotate, and the cleaning brush slides along the surface of the photovoltaic panel to clean the dust. When the photovoltaic panel is unfolded, the reverse action is used to clean the dust again. The mechanical movement of the photovoltaic panel unfolding and retracting drives the dust cleaning, which does not require additional power and automatically removes surface dust, ensuring photovoltaic conversion efficiency and reducing manual maintenance costs.
[0012] Furthermore, the bird-repelling mechanism includes a top compartment located at the top of the bottom compartment. A bell assembly is installed at a non-central position at the bottom of the top compartment. A power assembly that cooperates with the bell assembly is installed at the central position at the bottom of the top compartment. A bird-repelling windmill is installed on the top of the top compartment, and the rotating shaft of the bird-repelling windmill provides power to the power assembly through a reduction gear set. An auxiliary winding mechanism that cooperates with the drive gear is installed inside the top compartment.
[0013] Through the above technical solution, the wind drives the bird-repelling windmill to rotate, and the energy is stored in the power component through the reduction gear set. When the energy is released, it triggers the bell component to make a sound. When the retraction device is activated, the auxiliary winding mechanism simultaneously replenishes the energy of the power component. The wind power and mechanical motion energy are integrated to drive the bird repelling mechanism. The visual deterrence of the windmill and the auditory bird repelling effect of the bell are combined to improve the bird repelling effect. Moreover, the energy is recycled, reducing power consumption.
[0014] Furthermore, the bell assembly includes a copper bell located at the bottom of the top compartment, a rotatable striking plate is fixedly mounted at a non-central position at the bottom of the top compartment, a fixing block is installed at the bottom of the top compartment near the striking plate, and a tension spring is installed on one side of the fixing block and fixedly connected to one side of the striking plate.
[0015] Through the above technical solution, the power component drives the striking plate to rotate against the tension of the spring, striking the copper bell to produce a sound. Then the spring resets, causing the striking plate to return to its original position. The repeated action produces a continuous sound. The intermittent bell sound is achieved through mechanical transmission. The sound is used to scare away birds. Combined with the visual deterrence of the windmill, the bird-scaring effect is enhanced. The structure is simple and durable.
[0016] Furthermore, the power assembly includes a rotatable inner ring located at the center of the bottom of the top compartment. The inner ring is fitted around the bottom of the outer side of the bird-repelling windmill shaft. A coil spring is provided on the outer ring of the inner ring, and a rotating outer ring is provided on the outer ring of the coil spring. The inner and outer ends of the coil spring are fixedly connected to the inner and outer rings, respectively. An actuating block that cooperates with the striking plate is installed on the outer ring of the rotating outer ring.
[0017] With the above technical solution, when the inner ring is driven to rotate, the coil spring is twisted to store energy. When the coiling force exceeds the limit of the tension spring, the outer ring rotates to drive the toggle block to rotate, pushing the striking plate to strike the copper bell. After the coiling force is released, it re-stores energy. Energy storage and release are achieved through the coil spring, so that the bell sound is emitted intermittently, preventing birds from adapting, improving the bird deterrence effect, and reducing the dependence on electricity by using mechanical energy storage.
[0018] Furthermore, the reduction gear set includes a second large gear installed on the outer side of the rotating inner ring, a second rotating shaft is provided at the bottom non-center position of the top compartment, and a first large gear and a second small gear are installed sequentially from top to bottom on the outer side of the second rotating shaft. The second small gear meshes with the second large gear. The rotating shaft of the bird-repelling windmill extends into the interior of the top compartment and is equipped with a first small gear that meshes with the first large gear.
[0019] Through the above technical solution, the bird-repelling windmill shaft drives the first small gear to rotate. Through the reduction transmission of the first large gear, the second small gear, and the second large gear, the rotation speed of the inner ring is reduced, and the torque is increased to drive the coil spring to store energy. The reduction gear set increases the torque output, ensuring that the coil spring can effectively store energy. Even at low wind speeds, it can provide sufficient power to the power components and enhance the adaptability of the device.
[0020] Furthermore, the top chamber has a frustum-shaped structure, and a protective cover is installed on the outside of the bird-repelling windmill shaft, with the protective cover located above the top chamber.
[0021] Through the above technical solutions, the frustum-shaped top compartment reduces wind resistance and is not conducive to birds landing. The protective cover shields against rain and dust, protects the internal gear set and power components, extends the life of internal components, and adapts to complex outdoor environments.
[0022] Furthermore, the auxiliary gear-up mechanism includes a third rotating shaft located at a non-central position at the bottom of the top compartment. The bottom end of the third rotating shaft extends into the interior of the bottom compartment and is equipped with a transmission gear that meshes with the drive gear. A turntable is installed at the top of the third rotating shaft, and plastic actuating plates that cooperate with the second large gear are evenly installed on the outer ring of the turntable.
[0023] Through the above technical solution, when the active gear rotates, it drives the transmission gear and the third rotating shaft to rotate. The plastic actuating piece on the turntable actuates the second large gear, which assists in rotating the inner ring, thus tightening the coil spring. The power of the retraction device is used to replenish the energy of the coil spring, improving energy utilization efficiency, ensuring sufficient energy storage of the coil spring, and maintaining the continuous bird-repelling effect.
[0024] The beneficial effects of the present invention are as follows: (1) The present invention can automatically extend the photovoltaic panel during the day and simultaneously retract the lighting lamp downwards through the extension and retraction mechanism, avoiding birds from staying on the lighting lamp during the day and thus getting bird droppings. In the evening, the photovoltaic panel is retracted and the lighting lamp is extended for illumination, avoiding birds from staying on the photovoltaic panel after dusk and getting bird droppings, which would affect the subsequent conversion efficiency of the photovoltaic panel; (2) During the extension or retraction of the photovoltaic panel, the present invention can automatically clean the surface of the photovoltaic panel by utilizing the change in the position of the photovoltaic panel mounting frame. (3) This invention utilizes wind power to drive the bird-repelling windmill to rotate, thereby automatically tightening the coil spring. When the coiling force of the coil spring exceeds the limits of the striking plate and tension spring, it can automatically release the coiling force and drive the striking plate to strike the copper bell, thereby producing a sound. Combined with the bird-repelling windmill, it can further improve the bird-repelling effect, and it can still have the bird-repelling function when the bird-repelling windmill loses its function in the evening. At the same time, the winding and unwinding mechanism can also automatically tighten the coil spring through the auxiliary winding mechanism during the winding and unwinding process of driving the photovoltaic panel and lighting lamp, thereby improving the utilization efficiency of electricity.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0041] like Figures 1-7 , Figures 9-10 and Figure 13As shown in the figure, a photovoltaic power generation outdoor lighting device of this embodiment includes a lamp post 1 and a base 2. A lighting lamp 3 and a mounting frame 4 are respectively hinged to the top of both sides of the base 2. A photovoltaic panel 5 is mounted on the surface of the mounting frame 4. The interior of the base 2 is provided with a retraction mechanism 6 for adjusting the angle of the lighting lamp 3 and the mounting frame 4. The retraction mechanism 6 includes two pairs of first rotating shafts 601, located at the inner top and inner bottom of the base 2 respectively. On the same side, two sets of first rotating shafts 601 are connected to lead screws 602 via universal joints. The two sets of lead screws 602 are inclined. The lead screw 602 has an internal threaded ring 603 on its outer thread. Two sets of internal threaded rings 603 are located at the top and bottom of the lead screw 602, respectively. A hinge rod 604 is hinged to the outer side of each internal threaded ring 603, and the ends of the two hinge rods 604 away from the internal threaded rings 603 are respectively hinged to the inner sides of the lighting lamp 3 and the mounting bracket 4. The outer side of the base 2 has symmetrically opened strip-shaped through slots 605 that cooperate with the hinge rods 604. A drive device 606 for driving the two sets of lead screws 602 to rotate is located at the top of the base 2. The drive device 606 includes a servo motor 6061 located at the top of the base 2. The output shaft of 061 is equipped with a drive gear 6062. On the outer sides of the top pair of first rotating shafts 601, driven gears 6063 mesh with the drive gear 6062. The servo motor 6061 drives the drive gear 6062 to rotate. Through meshing with the two sets of driven gears 6063, it drives the two pairs of first rotating shafts 601 and the lead screw 602 to rotate synchronously. When the lead screw 602 rotates, the outer internal threaded ring 603 moves axially along the lead screw, pushing the lighting lamp 3 and the mounting bracket 4 to rotate around the hinge axis of the base chamber 2 via the hinge rod 604 (passing through the strip groove 605). The lead screw 602 rotates counterclockwise. When rotating, the lighting lamp 3 flips outward and unfolds, while the mounting frame 4 rotates downward and folds the photovoltaic panel 5. When the lead screw 602 rotates clockwise, the lighting lamp 3 folds inward and unfolds, while the mounting frame 4 rotates upward and unfolds the photovoltaic panel 5. This achieves synchronous and reverse unfolding and folding of the photovoltaic panel 5 and the lighting lamp 3. During the day, the photovoltaic panel emits light to receive illumination, while the lighting lamp folds to prevent birds from landing and getting bird droppings. In the evening, the photovoltaic panel folds up and the lighting lamp emits light to prevent birds from landing on the photovoltaic panel. Folding up the photovoltaic panel reduces direct impact from hail and extends its service life. The gear transmission of the drive device ensures precise and synchronized movements, improving the automation level of the device.
[0042] like Figures 1-6 , Figure 8 and Figure 13As shown, in this embodiment, the mounting frame 4 has a dust removal mechanism 7 at both ends for cleaning dust from the surface of the photovoltaic panel 5. The dust removal mechanism 7 includes a rotating rod 701 positioned horizontally in the middle of the bottom chamber 2. Both ends of the rotating rod 701 extend to the outside of the bottom chamber 2 and are symmetrically equipped with connecting rods 702. Both ends of the mounting frame 4 are provided with sliding seats 703, and cleaning brushes 704 are installed on the outer sides of the two sets of connecting rods 702. The end of the connecting rod 702 away from the rotating rod 701 is hinged to an adjacent set of sliding seats 703. The middle of the outer side of the rotating rod 701... A fixing ring 705 is installed at the position. Torsion springs 706 are symmetrically sleeved at both ends of the outer side of the rotating rod 701. The two ends of the torsion springs 706 are fixedly connected to the fixing ring 705 and the inner wall of the bottom chamber 2, respectively. When the photovoltaic panel 5 is extended or retracted, the mounting frame 4 rotates to drive the sliding seat 703 to move. With the torque of the torsion springs 706, the rotating rod 701 drives the connecting rod 702 to rotate. The connecting rod drives the cleaning brush 704 to move synchronously with the sliding seat and slide along the surface of the photovoltaic panel 5. When the photovoltaic panel 5 is extended, the reverse action is performed to clean the dust again. The mechanical movement of the photovoltaic panel 5 extending and retracting drives the dust cleaning.
[0043] like Figures 1-6 , Figures 9-11 and Figure 14As shown, in this embodiment, a bird-repelling mechanism 8 for repelling birds is provided on the top of the bottom compartment 2. The bird-repelling mechanism 8 includes a top compartment 801 located on the top of the bottom compartment 2. A bell assembly 802 is provided at a non-central position at the bottom of the top compartment 801. A power assembly 803 that cooperates with the bell assembly 802 is provided at the center position at the bottom of the top compartment 801. A bird-repelling windmill 805 is provided on the top of the top compartment 801, and the rotating shaft of the bird-repelling windmill 805 provides power to the power assembly 803 through a reduction gear set 804. The bell assembly 802 includes a copper bell 8021 located at the bottom of the top compartment 801. A rotatable striking plate 8022 is fixedly provided at a non-central position at the bottom of the top compartment 801. A bell is installed at the bottom of the top compartment 801 near the striking plate 8022. The device includes a fixing block 8023, with a tension spring 8024 fixedly connected to one side of the striking plate 8022. The power assembly 803 includes a rotating inner ring 8031 rotatable at the center of the bottom of the top chamber 801. The rotating inner ring 8031 is sleeved on the bottom end of the outer side of the bird-repelling windmill 805 shaft. A coil spring 8032 is provided on the outer ring of the rotating inner ring 8031, and a rotating outer ring 8033 is provided on the outer ring of the coil spring 8032. The inner and outer ends of the coil spring 8032 are fixedly connected to the rotating inner ring 8031 and the rotating outer ring 8033, respectively. A toggle block 8034 cooperating with the striking plate 8022 is installed on the outer ring of the rotating outer ring 8033. The reduction gear set 804 includes gears installed on the outer side of the rotating inner ring 8031. The second large gear 8045, and the second rotating shaft 8042 located at the bottom non-center position inside the top chamber 801, with the first large gear 8043 and the second small gear 8044 sequentially installed on the outer side of the second rotating shaft 8042 from top to bottom. The second small gear 8044 meshes with the second large gear 8045. The rotating shaft of the bird-repelling windmill 805 extends into the interior of the top chamber 801 and is equipped with a first small gear 8041 that meshes with the first large gear 8043. The top chamber 801 has a frustum-shaped structure. A protective cover 806 is installed on the outer side of the rotating shaft of the bird-repelling windmill 805, and the protective cover 806 is located above the top chamber 801. The wind drives the bird-repelling windmill 805 to rotate, and its rotating shaft is connected by the first small gear 8041 and the first large gear 8045. 3. The reduction gear set 804, composed of the second small gear 8044 and the second large gear 8045, reduces speed and increases torque, driving the inner rotating ring 8031 to rotate. This causes the coil spring 8032 to be twisted and store energy (at this time, the outer rotating ring 8033 cannot rotate due to the limit of the striking plate 8022). When the energy stored in the coil spring 8032 reaches the tension limit of the tension spring 8024, the outer rotating ring 8033 suddenly rotates. The actuating block 8034 of the outer ring pushes the striking plate 8022 to rotate around a fixed axis. One end of the striking plate strikes the copper bell 8021 and makes a sound. Then the tension spring 8024 pulls the striking plate to reset, and the coil spring re-stores energy, forming a periodic striking. The dynamic visual deterrence of the bird-repelling windmill 805 combined with the intermittent sound of the copper bell 8021 provides a double stimulus to birds, significantly improving the bird-repelling effect.Utilizing wind power for automatic energy storage and release, it eliminates the need for photovoltaic power, making it energy-efficient and environmentally friendly; the frustum-shaped top chamber 801 reduces wind resistance, and the protective cover 806 protects the internal components, adapting to complex outdoor environments.
[0044] like Figures 9-10 and Figure 12 As shown, the top compartment 801 of this embodiment is internally provided with an auxiliary gearing mechanism 9 that cooperates with the drive gear 6062. The auxiliary gearing mechanism 9 includes a third rotating shaft 901 located at a non-central position at the bottom of the top compartment 801. The bottom end of the third rotating shaft 901 extends into the interior of the bottom compartment 2 and is equipped with a transmission gear 902 that meshes with the drive gear 6062. A turntable 903 is installed at the top end of the third rotating shaft 901, and plastic actuating plates 904 that cooperate with the second large gear 8045 are evenly installed on the outer ring of the turntable 903. The rotation of the drive gear 6062 drives the meshing transmission gear 902 to rotate, which in turn drives the third rotating shaft 901 to rotate. When the disc 903 rotates, the plastic actuating piece 904 on the outer ring of the disc rotates with the disc and actuates the second large gear 8045 to rotate, which in turn drives the inner ring 8031 to rotate, replenishing the energy stored in the coil spring 8032. When the bird-repelling windmill 805 drives the second large gear 8045 to rotate clockwise, the plastic actuating piece 904, due to its flexible and deformable material, does not affect the normal rotation of the windmill. It converts the mechanical motion energy of the retraction mechanism into the energy stored in the coil spring 8032, supplementing the energy demand when the wind is insufficient, ensuring that the coil spring continuously and effectively stores energy, and maintaining the regularity of the bird-repelling bell sound. The unidirectional transmission design of the plastic actuating piece avoids energy loss, improves the overall energy utilization efficiency, and enhances the stability of the bird-repelling function.
[0045] The working principle of this embodiment is as follows: In the evening, the servo motor 6061 drives the drive gear 6062 to rotate. Through the transmission of the drive gear 6062 and the driven gear 6063, the two sets of lead screws 602 rotate synchronously and counterclockwise, forcing the internal thread ring 603 to cooperate with the hinge rod 604 to drive the lighting lamp 3 to flip outward and open with its hinge shaft axis on the outside of the bottom compartment 2. Meanwhile, the mounting bracket 4, along with the photovoltaic panel 5, rotates downward and retracts. Then, the lighting lamp 3 is controlled to provide illumination. During this process, the torque of the torsion spring 706 forces the rotating rod 701 to rotate with the connecting rod 702, causing the sliding seat 703 to carry the cleaning brush 704. The photovoltaic panel 5 slides downwards on the mounting bracket 4, and the cleaning brush 704 cleans the surface of the photovoltaic panel 5. During the day, the two sets of lead screws 602 are controlled to rotate clockwise, causing the lighting lamp 3 to rotate and retract, while the mounting bracket 4 rotates and unfolds the photovoltaic panel 5. During this process, the cleaning brush 704 can clean the surface of the photovoltaic panel 5 again. When the wind drives the bird-repelling windmill 805 to rotate, the rotating rod of the bird-repelling windmill 805 drives the inner ring 8031 to rotate through the transmission of the first small gear 8041, the first large gear 8043, the second small gear 8044, and the second large gear 8045, while the striking plate 8022... One end of the spring abuts against the actuating block 8034, preventing the outer rotating ring 8033 from rotating. As the inner rotating ring 8031 rotates continuously, it applies increasing tension to the coil spring 8032. When the coiling force of the coil spring 8032 overcomes the restriction imposed on the actuating block 8034 by the tension spring 8024 and the striking plate 8022, the coil spring 8032 drives the outer rotating ring 8033 and the actuating block 8034 to rotate rapidly. During this process, the actuating block 8034 continuously pushes the striking plate 8022 to rotate around its hinge axis. Combined with the tension spring 8024, this causes the striking plate 8022 to swing back and forth continuously, causing one end of the striking plate 8022 to continuously strike the copper bell 80. 21. A sound is emitted. When the coiling force of the coil spring 8032 is less than the restriction of the striking plate 8022 on the toggle block 8034, the outer ring 8033 can no longer rotate. When the drive gear 6062 rotates clockwise, the drive gear 6062 drives the turntable 903 to rotate counterclockwise through the transmission gear 902. The plastic toggle piece 904 on the outside of the turntable 903 will drive the second large gear 8045 to rotate, which will tighten the coil spring 8032. When the bird-repelling windmill 805 drives the second large gear 8045 to rotate clockwise, the second large gear 8045 cannot drive the turntable 903 to rotate through the plastic toggle piece 904.
