Description

Technical Field

[0001] The present invention relates to the technical field of solar street lamps, and in particular to an adjustable solar street lamp. Background Art

[0002] Solar street lights, as lighting devices that convert solar energy into electricity, not only save energy and reduce electricity consumption, but also reduce carbon emissions, meeting the modern society's demand for environmental protection and energy conservation. Therefore, solar street lights have been increasingly widely used in cities, villages, parks, roads and other fields.

[0003] Despite the numerous advantages of solar street lights, their performance and efficiency in practical applications still have certain shortcomings. Patent application publication number CN118208686A discloses a solar street light with adjustable photovoltaic panel angle, comprising a lamp post with a fixed cylinder fixed at the top, a support plate rotatably mounted on the top of the fixed cylinder, and a photovoltaic panel rotatably mounted on the support plate; an angle adjustment mechanism comprising an adjustment screw rotatably mounted within the fixed cylinder for adjusting the angle and orientation of the photovoltaic panel, the top of the adjustment screw rotatably connected to the photovoltaic panel, a ratchet threadedly connected to the outer circumference of the adjustment screw, the ratchet rotatably mounted within the fixed cylinder, and a locking structure for securing the ratchet; and an azimuth adjustment mechanism comprising two synchronized arc plates fixed and symmetrically disposed between the ratchet and the support plate, and an unlocking mechanism rotatably mounted on the end of the adjustment screw away from the photovoltaic panel.

[0004] This patent and the prior art have the following technical problems in actual use:

[0005] 1. The photovoltaic panels of existing solar street lights are mostly flat. This means that in order to fully utilize solar energy, it is necessary to add an angle adjustment structure to track the sun, which is difficult to adjust. In addition, the photovoltaic panels and lamps are designed separately, which makes them less aesthetically pleasing.

[0006] 2. The existing lamps are fixed in position, and the illumination angle and illumination method cannot be adjusted, which limits the use scenarios of street lamps. Summary of the Invention

[0007] In order to solve the above problems, the present invention provides an adjustable solar street light.

[0008] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0011] Furthermore, outer plates are provided on both sides of the guide ring, and guide grooves are provided inside the outer plates. The distance between the guide grooves and the center of the rotating shaft gradually increases from bottom to top. A guide rod is fixedly installed on one end of the photovoltaic panel lampshade close to the slide. A guide hole is provided inside the slide, and the guide rod passes through the guide hole. A sliding column is provided on the end of the guide rod away from the slide, and the sliding column is slidably connected in the guide groove.

[0012] Furthermore, the outer ring of the mounting rod is provided with an outer convex strip, and the outer convex strip is designed to correspond to the inner elastic rope. The outer side of the mounting rod is sleeved with a rope guide disc, and the rope guide disc can slide along the outer convex strip. The inner ring of the rope guide disc is provided with multiple groups of clamping grooves, and the clamping grooves are designed to correspond to the inner elastic rope. The inner sliding connection of the clamping groove is provided with a clamping plate, and the end of the clamping plate close to the outer convex strip is inclined. The end of the clamping groove away from the mounting rod is provided with a spring piece, and rope holes are penetrated through the interior of the clamping groove and the interior of the clamping plate. When the clamping plate is pressed against the mounting rod, the center lines of the rope holes on the clamping groove and the clamping plate coincide.

[0013] Furthermore, the inner elastic rope consists of an elastic part and a tensile part, the length of the elastic part is greater than that of the tensile part, and the tensile part passes through the rope hole.

[0014] Furthermore, a lifting screw is rotatably installed inside the slide seat, a nut block is welded on the outer side of the rope guide disc, and the nut block is threadedly connected to the lifting screw.

[0015] Furthermore, a driving motor is provided inside the lamp pole, and an output shaft is provided at the output end of the driving motor, the output shaft passes through the guide ring, and a driving wheel 2 is fixedly installed on the top end of the output shaft. The rotating shaft is rotatably installed between two sets of outer plates, and a transmission wheel is fixedly installed on the outer side of the rotating shaft, and the transmission wheel is engaged with the driving wheel 2.

[0016] Furthermore, an electric telescopic rod is fixedly installed inside the lamp pole, and a driving motor is fixedly installed on the top of the telescopic end of the electric telescopic rod, and a driving wheel 1 is fixedly installed on the outside of the output shaft, and an arc-shaped slide groove is opened inside the outer plate, and the center of the arc-shaped slide groove is located on the axis of the rotating shaft, and an arc-shaped slide groove is slidably connected inside the arc-shaped slide groove, and the curvature of the arc-shaped slide groove is smaller than the curvature of the arc-shaped slide groove, and an outer arc-shaped driving bar is fixedly installed on the outside of the arc-shaped slide groove, and an inner arc-shaped driving bar is fixedly installed on the inside of the arc-shaped slide groove.

[0017] Furthermore, the guide groove and the arc-shaped sliding groove are both designed to be symmetrical about the rotation axis.

[0018] Furthermore, mounting holes are provided at the bottom end of the outer plate and the top end of the lamp pole.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The photovoltaic panel lampshade of the present invention adopts a trumpet-shaped design. During the day, the opening of the photovoltaic panel lampshade faces upward, so that the photovoltaic panel can capture a wider range of solar radiation. Compared with flat photovoltaic panels, the curved surface of the trumpet-shaped photovoltaic panel can better receive sunlight at different angles and directions. Especially in cases where the angle of sunlight varies greatly (such as in the morning and evening or in winter), the trumpet-shaped design can more effectively capture sunlight and improve the overall efficiency of the photovoltaic panel. At night, the elastic reflective liner retracts into the inside of the photovoltaic panel lampshade, and the opening of the photovoltaic panel lampshade faces obliquely downward, which can reflect light and evenly diffuse the light to a wider area, reducing the situation where light directly hits the eyes, thereby reducing glare. Therefore, the lamp and photovoltaic panel are integrated into a design with a compact structure and high aesthetics.

[0021] 2. The present invention adopts the provision of an elastic reflective inner liner. When the photovoltaic panel lampshade is raised or lowered relative to the light source, the reflective elastic cover wipes the light-receiving surface of the photovoltaic panel lampshade, thereby solving the problem that the light-receiving surface of the trumpet-shaped photovoltaic panel is difficult to clean.

[0022] 3. The present invention can pull the inner elastic rope inward by pulling it toward the slide, thereby changing the reflection angle. At the same time, by controlling the rotation of the shaft, the shaft drives the slide to slide along the guide groove, so that the light source can be directed toward the back or front, and has a wide range of application scenarios.

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] like Figures 1-6 As shown, the adjustable solar street light includes a lamp pole 1, a guide ring 2 is welded to the top of the lamp pole 1, a guide groove 21 is opened inside the guide ring 2, a slide seat 5 is slidably connected inside the guide groove 21, a friction damper is provided between the slide seat 5 and the guide groove 21, and the device can be fixed by the design of the friction damper. A rotating shaft 4 is rotatably installed inside the guide ring 2, and the slide seat 5 is connected to the rotating shaft 4 through a transmission rod 51;

[0032] A mounting rod 52 is welded to the side of the slide 5 away from the rotating shaft 4, and a light source 6 is fixedly installed on the end of the mounting rod 52 away from the slide 5. A photovoltaic panel lampshade 7 is sleeved on the outside of the light source 6, and the photovoltaic panel lampshade 7 can be raised and lowered along the direction of the mounting rod 52. An elastic reflective liner 8 is provided on the inner side of the photovoltaic panel lampshade 7. The elastic reflective liner 8 is provided with multiple groups of external pull ropes 81 in a ring shape at one end away from the slide 5, and multiple groups of internal elastic ropes 82 are provided in a ring shape at the other end. The external pull ropes 81 and the internal elastic ropes 82 are both fixedly mounted on the slide 5, and the external pull ropes 81 are located on the outside of the photovoltaic panel lampshade 7, and the internal elastic ropes 82 are located on the inside of the photovoltaic panel lampshade 7.

[0033] During the day, the rotating shaft 4 drives the slide 5 to slide upwards through the transmission rod 51, and the slide 5 drives the light source 6 and the photovoltaic panel lampshade 7 to slide upwards, and the photovoltaic panel lampshade 7 opens upwards. Figure 2 As shown, at the same time, the photovoltaic panel lampshade 7 slides relative to the sliding seat 5 and the elastic reflective inner liner 8 in the direction away from the guide ring 2. Since the outer pull rope 81 has no elastic force, the inner elastic rope 82 has elastic force and can be stretched. Therefore, when the photovoltaic panel lampshade 7 slides upward relative to the elastic reflective inner liner 8, the elastic reflective inner liner 8 slides from the inside of the photovoltaic panel lampshade 7 to the outside of the photovoltaic panel lampshade 7. It should be noted that a small part of the elastic reflective inner liner 8 is still located in the photovoltaic panel lampshade 7, and this part does not cause light blocking, and can also ensure that the elastic reflective inner liner 8 is smoothly reset. At this time, the light receiving surface inside the photovoltaic panel lampshade 7 is illuminated by sunlight, and the photovoltaic panel lampshade 7 generates electricity. The trumpet-shaped photovoltaic panel lampshade 7 enables the photovoltaic panel to capture a wider range of solar radiation. Compared with a flat photovoltaic panel, the curved surface of the trumpet-shaped photovoltaic panel can better receive sunlight at different angles and directions. Especially when the angle of sunlight varies greatly (such as in the morning and evening or in winter), the trumpet-shaped design can more effectively capture sunlight and improve the overall efficiency of the photovoltaic panel.

[0034] At night, the rotating shaft 4 drives the slide 5 to slide downward through the transmission rod 51, and the slide 5 drives the light source 6 and the photovoltaic panel lampshade 7 to slide downward. The opening of the photovoltaic panel lampshade 7 is tilted downward. Figure 1 As shown, the photovoltaic panel lampshade 7 is reset and the elastic reflective liner 8 is retracted into the photovoltaic panel lampshade 7. At this time, the light receiving surface of the photovoltaic panel lampshade 7 can reflect the light through the elastic reflective liner 8, and evenly diffuse the light to a wider area, reducing the situation where light directly hits the eyes, thereby reducing glare. Therefore, the lamp and the photovoltaic panel are integrated into a design with a compact structure and high aesthetics.

[0035] When the trumpet-shaped photovoltaic panel lampshade 7 needs to be cleaned, the slide 5 is controlled to slide up and down along the guide groove 21, and the elastic reflective liner 8 can wipe the light receiving surface of the photovoltaic panel lampshade 7, solving the problem that the trumpet-shaped photovoltaic panel lampshade 7 is difficult to clean.

[0036] The maximum diameter of the photovoltaic panel lampshade 7 is 0.9m and the minimum diameter is 0.6m. The depth design of the trumpet shape should take into account the optimal lighting angle and diffusion effect. Under normal circumstances, the depth is 1 / 3 to 1 / 2 of the maximum diameter. This can ensure that low-angle sunlight is effectively captured. The depth can be designed to be 0.3m to 0.45m. The material thickness of the elastic reflective liner 8 is designed to be between 1-2mm, and the inner surface is coated with a reflective coating. The outer surface, which is the fitting surface with the photovoltaic panel lampshade 7, is bonded with a plush layer to improve the cleaning effect. The inner elastic rope 82 is made of highly elastic synthetic rubber material. This type of material has strong elasticity, durability and weather resistance. The rubber material can maintain elasticity during long-term use and adapt to temperature changes and sunlight exposure. The diameter of the inner elastic rope 82 is designed to be between 3mm and 5mm, which can provide the necessary strength without affecting the sliding process. The elastic reflective liner 8 needs to have a certain degree of elasticity, but its elasticity requirement is relatively low. Its design goal is to ensure a good reflection effect by adapting to the shape of the photovoltaic panel lampshade 7, without necessarily over-stretching. Excessive elasticity may cause the elastic reflective liner 8 to deform during the sliding process of the photovoltaic panel lampshade 7, affecting the light reflection effect. Therefore, the elasticity of the elastic reflective liner 8 can be relatively moderate, providing a certain flexibility, but it does not need to have strong elasticity like the inner elastic rope 82. The material of the elastic reflective liner 8 is thermoplastic elastomer. These materials have good elasticity and durability, can be deformed to a certain extent without losing their original shape, and have strong weather resistance and heat resistance.

[0037] It also includes that outer plates 3 are provided on both sides of the guide ring 2, and a guide groove 31 is opened inside the outer plate 3. The center distance between the guide groove 31 and the rotating shaft 4 gradually increases from bottom to top. A guide rod 71 is fixedly installed on the end of the photovoltaic panel lampshade 7 close to the slide 5. A guide hole is opened inside the slide 5, and the guide rod 71 passes through the guide hole. A sliding column is provided on the end of the guide rod 71 away from the slide 5, and the sliding column is slidably connected in the guide groove 31.

[0038] Furthermore, mounting holes are provided at the bottom end of the outer panel 3 and the top end of the lamp pole 1 to improve the stability of the outer panel 3 .

[0039] During the day, the rotating shaft 4 drives the slide 5 to slide upward through the transmission rod 51, and the slide 5 drives the light source 6 and the photovoltaic panel lampshade 7 to slide upward, with the opening of the photovoltaic panel lampshade 7 facing upward. At the same time, the slide 5 drives the slide column to slide along the guide groove 31. Since the center distance between the guide groove 31 and the rotating shaft 4 gradually increases from bottom to top, the slide column pushes the photovoltaic panel lampshade 7 to slide away from the guide ring 2 relative to the slide 5 and the elastic reflective inner liner 8 through the guide rod 71. No additional drive is required. When the slide 5 slides, the photovoltaic panel lampshade 7 also extends and retracts at the same time, and the structure is simple and compact.

[0040] On the basis of the above embodiment, it also includes that the outer ring of the mounting rod 52 is provided with an outer convex strip 53, and the outer convex strip 53 is designed corresponding to the inner elastic rope 82. The outer side of the mounting rod 52 is sleeved with a rope guide disc 54, and the rope guide disc 54 can slide along the outer convex strip 53. The inner ring of the rope guide disc 54 is provided with multiple groups of clamping grooves 55, and the clamping grooves 55 are designed corresponding to the inner elastic rope 82. The inner sliding connection of the clamping groove 55 is provided with a splint 56, and the end of the splint 56 close to the outer convex strip 53 is inclined. The end of the clamping groove 55 away from the mounting rod 52 is provided with a spring piece 57. Rope holes are penetrated through the interior of the clamping groove 55 and the interior of the splint 56. When the splint 56 is pressed against the mounting rod 52, the center lines of the rope holes on the clamping groove 55 and the splint 56 coincide.

[0041] Furthermore, the inner elastic cord 82 is composed of an elastic portion 821 and a tensile portion 822 . The elastic portion 821 is longer than the tensile portion 822 , and the tensile portion 822 passes through the cord hole.

[0042] When the reflection angle of the elastic reflective liner 8 needs to be adjusted, the rope guide disc 54 is controlled to slide toward the guide ring 2. At this time, the outer convex strip 53 pushes the splint 56 away from the mounting rod 52 through the inclined surface of the splint 56. The splint 56 squeezes the spring piece 57, and the rope hole on the splint 56 is misaligned with the rope hole on the clamping groove 55, so that the tensile part 822 clamps it. At this time, the rope guide disc 54 pulls the elastic reflective liner 8 through the tensile part 822, and the other end of the elastic reflective liner 8 is restricted by the external pull rope 81. At this time, the elastic reflective liner 8 is retracted toward the light source 6, and the taper of the elastic reflective liner 8 changes, thereby changing the reflection angle.

[0043] On the basis of the above embodiment, the present invention further includes that a lifting screw 59 is rotatably installed inside the slide 5 , a nut block 58 is welded to the outer side of the rope guide disc 54 , and the nut block 58 is threadedly connected to the lifting screw 59 .

[0044] By controlling the rotation of the lifting screw 59 , the lifting screw 59 drives the rope guide disc 54 to slide along the outer protruding strip 53 through the nut block 58 .

[0045] On the basis of the above embodiment, it also includes that a driving motor 12 is provided inside the lamp pole 1, and an output shaft is provided at the output end of the driving motor 12, the output shaft passes through the guide ring 2, and a driving wheel 2 14 is fixedly installed on the top of the output shaft, the rotating shaft 4 is rotatably installed between the two groups of outer plates 3, and a transmission wheel 41 is fixedly installed on the outer side of the rotating shaft 4, and the transmission wheel 41 is engaged with the driving wheel 2 14.

[0046] The driving motor 12 of this embodiment is arranged in a vertical direction and is hidden in the lamp pole 1, which is aesthetically pleasing. When the driving motor 12 is energized, it drives the second driving wheel 14 to rotate, and the second driving wheel 14 drives the rotating shaft 4 to rotate through the transmission wheel 41, and the transmission is stable.

[0047] On the basis of the above embodiment, it also includes an electric telescopic rod 11 fixedly installed inside the lamp pole 1, a drive motor 12 fixedly installed on the top of the telescopic end of the electric telescopic rod 11, a drive wheel 13 fixedly installed on the outside of the output shaft, an arc-shaped slide 32 is opened inside the outer plate 3, the center of the arc-shaped slide 32 is located on the axis of the rotating shaft 4, and an arc-shaped slide 33 is slidably connected to the inside of the arc-shaped slide 32. The curvature of the arc-shaped slide 33 is smaller than the curvature of the arc-shaped slide 32. An outer arc-shaped drive bar 34 is fixedly installed on the outside of the arc-shaped slide 33. An inner arc-shaped drive bar 35 is fixedly installed on the inner side. When the driving wheel 2 14 is engaged with the transmission wheel 41, the driving wheel 13 is located above the inner arc-shaped drive bar 35. A lifting wheel 510 is fixedly installed on the end of the lifting screw 59 away from the rope guide disc 54. The lifting wheel 510 is engaged with the outer arc-shaped drive bar 34. When the slide 5 is at the bottom, the lifting wheel 510 is located above the outer arc-shaped drive bar 34. Through this design, it is ensured that when the slide 5 swings upward, the lifting wheel 510 will not engage with the outer arc-shaped drive bar 34, and the splint 56 will not clamp the tensile part 822.

[0048] At night, the driving motor 12 is energized to drive the second driving wheel 14 to rotate, and the second driving wheel 14 drives the rotating shaft 4 to rotate through the transmission wheel 41. The rotating shaft 4 drives the slide 5 to slide downward through the transmission rod 51. The slide 5 drives the light source 6 and the photovoltaic panel lampshade 7 to slide downward. The opening of the photovoltaic panel lampshade 7 is tilted downward. Figure 1 As shown, the photovoltaic panel lampshade 7 is reset under the action of the guide rod 71 and the guide groove 31, and the elastic reflective liner 8 is retracted into the photovoltaic panel lampshade 7. At this time, the light receiving surface of the photovoltaic panel lampshade 7 passes through the elastic reflective liner 8 and can reflect the light;

[0049] When the reflection angle needs to be adjusted, the electric telescopic rod 11 is controlled to operate, the electric telescopic rod 11 drives the driving motor 12 to descend, the driving motor 12 drives the output shaft to descend, the output shaft drives the driving wheel 13 and the driving wheel 2 14 to descend, at this time the driving wheel 2 14 is away from the transmission wheel 41, the driving wheel 13 is engaged with the inner arc driving strip 35, and then the driving motor 12 is controlled to be energized, the driving motor 12 drives the output shaft to rotate, the conveying shaft drives the driving wheel 13 to rotate, the driving wheel 13 drives the arc slide 33 to slide along the arc slide groove 32 through the inner arc driving strip 35, the arc slide 33 drives the outer arc driving strip 34 to engage with the lifting wheel 510, and the outer arc driving strip 34 drives the lifting wheel 510 to rotate, and the lifting wheel 510 is lifted. The lowering wheel 510 drives the lifting screw 59 to rotate, and the lifting screw 59 drives the guide rope disc 54 to slide along the outer convex strip 53 through the nut block 58. The guide rope disc 54 slides toward the guide ring 2. At this time, the outer convex strip 53 pushes the splint 56 away from the mounting rod 52 through the inclined surface of the splint 56. The splint 56 squeezes the spring piece 57, and the rope hole on the splint 56 is misaligned with the rope hole on the clamping groove 55 to achieve clamping of the tensile part 822. At this time, the guide rope disc 54 pulls the elastic reflective inner liner 8 through the tensile part 822. The other end of the elastic reflective inner liner 8 is restricted by the external pull rope 81. At this time, the elastic reflective inner liner 8 is retracted toward the light source 6, and the taper of the elastic reflective inner liner 8 changes, thereby changing the reflection angle. There is no need to set up multiple sets of drives, and the control is simple.

[0050] On the basis of the above embodiment, the guide groove 31 and the arc-shaped sliding groove 32 are both designed to be symmetrical with respect to the rotating shaft 4 .

[0051] With this design, the photovoltaic panel lampshade 7 and the lifting screw 59 can be driven regardless of whether the slide 5 turns to the left or the right.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
