Description

Technical Field

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

[0002] The LED solar street lamp is a green and energy-saving street lamp, and has the advantages of high luminous efficiency, low power consumption, long service life, low working temperature, and safe, stable and reliable. It is more and more widely used in today's roads. The LED street lamp receives sunlight through a solar panel and converts it into electrical energy to provide light for the LED lamp, without additional power supply, and has high economic benefits in the later stage.

[0003] However, the lamp body and the solar panel of the existing LED solar street lamp are separately installed at the top of the lamp post, which makes the installation troublesome and results in low installation efficiency. Moreover, in conventional street lamps, the lamp body and the solar panel are set as an integral body, which makes it inconvenient to adjust the orientation of the solar panel and the lamp body. It is necessary to adjust the orientation of the solar panel and the lamp body before pre-installing the lamp post. Adjusting the overall angles of the lamp post, the lamp body and the solar panel also causes trouble in installing the street lamp and inconvenience in adjusting the angle of the LED lamp, affecting the overall construction efficiency. Summary of the Invention

[0004] The present invention provides an LED solar street lamp, which has the advantages of high installation efficiency of the street lamp and convenient separate adjustment of the orientations of the solar panel and the lamp body, and solves the technical problems mentioned in the background art.

[0007] Optionally, a positioning vertical tube is fixedly sleeved in the middle of the top end of the crossbeam frame plate. The folding support assembly includes a lower supporting plate movably sleeved outside the positioning vertical tube. The tops of both sides of the lower supporting plate are fixedly connected with upper supporting plates, and the upper supporting plates are perpendicular to the lower supporting plate. The middle parts of the two upper supporting plates are respectively coaxially rotatably connected with two lower supporting plates. The two lower supporting plates on each upper supporting plate are mutually offset. The tops of the two lower supporting plates are respectively rotatably connected with upper supporting plates. The tops of the two upper supporting plates are movably sleeved with upper supporting shafts. The tops of the two upper supporting shafts are respectively fixedly connected with supporting blocks. Both supporting blocks are fixedly connected with the bottom of the solar panel. A plurality of equally spaced slots are formed in the lower supporting plates. The two upper supporting plates and the two lower supporting plates on each upper supporting plate form a diamond-shaped support. The two ends of each upper supporting plate are respectively rotatably connected with adjusting support plates, and the tops of the two adjusting support plates are respectively movably sleeved with the slots on the two lower supporting plates through bolts.

[0008] Optionally, a groove is formed in the middle of the top end of the upper supporting plate, and the bottom end of the adjusting support plate is arranged in the groove at the top of the upper supporting plate.

[0009] Optionally, a passive gear ring is movably sleeved outside the positioning vertical tube. The top of the passive gear ring is movably connected with a pressing ring, and the pressing ring is movably sleeved outside the positioning vertical tube. An adjusting nut is threadedly sleeved on the positioning vertical tube. The top of the lower supporting plate is fixedly connected with a limiting gear ring located inside the passive gear ring. Refer to the figure. The outer cross-section of the positioning vertical tube is hexagonal, and the outer side wall of the positioning vertical tube is attached to the inner side wall of the passive gear ring. The outer teeth of the passive gear ring are meshed with the inner teeth of the limiting gear ring.

[0010] Optionally, a supporting block is arranged at the bottom of the side surface of the limiting sleeve. One end of the movable support frame plate away from the positioning support frame plate is clamped with the supporting block. A limiting device away from one side of the crossbeam frame plate is arranged at the bottom of the positioning support frame plate.

[0011] Optionally, the limiting device includes a limiting box fixedly installed at the bottom of the positioning support frame plate. A piston plate is movably sleeved inside the limiting box. One side of the piston plate facing the positioning support frame plate is fixedly connected with a baffle plate. One end of the baffle plate extends to the inside of the positioning support frame plate and is movably connected with one end of the moving support frame plate. The other side of the piston plate is fixedly connected with a pull shaft. The end of the pull shaft away from the piston plate extends to the outside of the limiting box and is fixedly connected with a pull ring.

[0012] Optionally, sliding grooves are formed on the inner walls of both sides of the positioning support frame plate. Convex strips are provided on both sides of the moving support frame plate. The convex strips are movably sleeved in the sliding grooves.

[0013] Optionally, the opening of the cross beam frame plate faces downward, and ventilation grooves are formed on both sides of the cross beam frame plate at a position away from one end of the box body. The ventilation grooves are located at a position away from one end of the box body. A wire arranging box is fixedly connected to the bottom of the inner cavity of the cross beam frame plate. The outer width value of the wire arranging box is smaller than the inner width value of the moving support frame plate.

[0014] The present invention provides an LED solar street lamp, which has the following beneficial effects:

[0015] 1. For this LED solar street lamp, the rubber friction sleeve inside the limiting sleeve closely adheres to the outside of the lamp post, and the pressing blocks on both sides of the insertion tube inserted into the lamp post press the inner wall of the insertion tube, so that the pressure of the outer side of the rubber friction sleeve against the lamp post is large enough. By using its friction force and the pressing blocks inside the lamp post, the limiting sleeve and the balance block are kept in a stable state as a whole, which is convenient for construction workers to install. Moreover, the limiting sleeve, the balance block and the rubber friction sleeve can be fixedly installed at any angle on the lamp post. Compared with the existing solar street lamps, it is convenient for installation and setting the angle of the LED lamp, ensuring that the LED lamp can face the road directly, avoiding the problem that the LED lamp can only be fixedly installed on one side of the lamp post and cannot be arbitrarily adjusted in the installation angle on the lamp post. When installing the street lamp, it is necessary to adjust the overall angles of the lamp post, the LED lamp and the solar panel, resulting in troublesome installation of the street lamp and inconvenient adjustment of the angle of the LED lamp.

[0016] 2. For this LED solar street lamp, the cross beam frame plate is rotatably connected to the balance block, and the positioning support frame plate is rotatably connected to the cross beam frame plate. Thus, a triangular support structure is formed by using the limiting sleeve, the cross beam frame plate, the positioning support frame plate and the moving support frame plate to support the solar panel, making the solar street lamp stable after installation and use. At the same time, the foldable support assembly provided on the cross beam frame plate is used to support the solar panel, which is convenient for construction workers to carry and install, and there is no need to install the LED lamp and the solar panel on the top of the lamp post in batches, further improving the installation efficiency.

[0017] 3. The LED solar street lamp is equipped with a folding support assembly composed of a lower support plate, an upper support plate, a lower support branch, an upper support branch, and an upper support shaft that are movably sleeved on the crossbeam frame plate. In cooperation with the passive gear ring sleeved outside the positioning vertical pipe at the top of the crossbeam frame plate, it is convenient for folding, carrying, and installation. At the same time, it can also adjust the orientation angle of the solar panel horizontally and vertically to ensure that the solar panel can receive sufficient sunlight and provide sufficient power for the illumination of the LED lamp.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 - Figure 2 , an LED solar street lamp, including a limit sleeve 1 sleeved outside the top of a lamp post 24. The top of the limit sleeve 1 is fixedly connected with a balance block 2, and the limit sleeve 1 and the balance block 2 are of an integral structure. On one side of the top of the balance block 2, there is a foldable LED lamp 6 and a solar panel 10. The inner side of the limit sleeve 1 is fixedly sleeved with a rubber friction sleeve 3. The inner side of the rubber friction sleeve 3 is closely attached to the outer side of the limit sleeve 1. The limit sleeve 1 and the rubber friction sleeve 3 are both semi-circular cylinders. Please refer to Figure 3 - Figure 5, a central part at the bottom end of the balance block 2 is fixedly connected with an insertion tube 19 located inside the lamp post 24. A group of pressing blocks 20 are movably sleeved on both sides of the insertion tube 19 respectively. The number of each group of pressing blocks 20 is three, and the three pressing blocks 20 are longitudinally linearly arrayed on the insertion tube 19. The inner side of the pressing block 20 is an inclined surface. A regulating screw shaft 22 is threadedly sleeved in the middle of the balance block 2. A gap is reserved between the outer side of the regulating screw shaft 22 and the inner side of the pressing block 20 to ensure that the outer side of the pressing block 20 can be retracted into the insertion tube 19, so as to facilitate inserting the insertion tube 19 into the lamp post 24. Three regulating plates 21 are fixedly sleeved on the regulating screw shaft 22, and the tops of the three regulating plates 21 are respectively movably connected with the inclined surfaces of the three pressing blocks 20 on both sides of the insertion tube 19. The top of the regulating screw shaft 22 is fixedly connected with a regulating turning plate 23 located outside the balance block 2. After inserting the insertion tube 19 at the bottom end of the balance block 2 into the lamp post 24, at this time, the rubber friction sleeve 3 just abuts against the outer side of the lamp post 24, and the inner wall of the lamp post 24 on the side away from the rubber friction sleeve 3 contacts the outer side of the insertion tube 19. Then, by rotating the regulating turning plate 23 to drive the regulating screw shaft 22 to rotate, controlling the regulating screw shaft 22 to drive the regulating plate 21 to move upward, the regulating plate 21 acts on the inclined surfaces of the two pressing blocks 20 on both sides, so that the two pressing blocks 20 extend out of the insertion tube 19 and fit against the inner wall of the lamp post 24. Under the extrusion of the two pressing blocks 20 on the inner wall of the lamp post 24, the lamp post 24 moves toward the side of the rubber friction sleeve 3, pressing the rubber friction sleeve 3. Thus, by using the frictional resistance of the inner side of the rubber friction sleeve 3 against the outer side of the lamp post 24, the whole of the limit sleeve 1, the balance block 2 and the insertion tube 19 is firmly fixed on the lamp post 24 and will not rotate. Therefore, the limit sleeve 1, the balance block 2 and the rubber friction sleeve 3 can be fixedly installed at any angle on the lamp post 24. Compared with the existing solar street lamps, it is convenient for installation and setting the angle of the LED lamp 6, ensuring that the LED lamp 6 can be directly facing the road surface, avoiding the problem that because the LED lamp 6 can only be fixedly installed on one side of the lamp post 24 and the installation angle of the LED lamp 6 on the lamp post 24 cannot be adjusted arbitrarily, when installing the street lamp, it is necessary to adjust the overall angles of the lamp post 24, the LED lamp 6 and the solar panel 10, resulting in troublesome installation of the street lamp and inconvenient adjustment of the angle of the LED lamp 6.

[0031] A through hole is formed in the middle of the regulating turning plate 23, which is convenient for construction workers to use a column to pass through the through hole, so as to facilitate rotating the regulating turning plate 23.

[0032] Please continue to refer to Figure 1 - Figure 2 , one side at the top of the balance block 2 is rotatably connected with a cross beam frame plate 4. The cross beam frame plate 4 can be rotated to a state parallel to the limit sleeve 1 by rotating relative to the balance block 2. One end of the cross beam frame plate 4 away from the balance block 2 is fixedly connected with a box body 5. The LED lamp 6 is arranged at the bottom of the box body 5. A folding support assembly is arranged at the top of the cross beam frame plate 4. The solar panel 10 is fixedly installed at the top of the folding support assembly.

[0033] Please refer to Figure 6 - Figure 7 , a positioning vertical pipe 25 is fixedly sleeved in the middle of the top end of the cross beam frame plate 4. The folding support assembly includes a lower support plate 11 movably sleeved outside the positioning vertical pipe 25. At the top of both sides of the lower support plate 11, upper support plates 12 are fixedly connected. The upper support plates 12 are perpendicular to the lower support plate 11. In the middle of the two upper support plates 12, two lower support plates 13 are coaxially rotatably connected respectively. The two lower support plates 13 on each upper support plate 12 are offset from each other. At the top ends of the two lower support plates 13, upper support plates 14 are rotatably connected respectively. At the top ends of the two upper support plates 14, upper support shafts 15 are movably sleeved. At the top ends of the two upper support shafts 15, support blocks 16 are fixedly connected respectively. Both support blocks 16 are fixedly connected to the bottom of the solar panel 10. A number of equally spaced slots are formed in the lower support plates 13. The two upper support plates 14 and the two lower support plates 13 on each upper support plate 12 form a diamond-shaped support. At both ends of each upper support plate 12, adjusting support plates 17 are rotatably connected respectively. At the top ends of the two adjusting support plates 17, they are movably sleeved with the slots on the two lower support plates 13 through bolts. By using the adjusting support plates 17 at both ends of the upper support plate 12 to support the lower support plates 13, while being convenient for folding and carrying, the longitudinal angle of the solar panel 10 can be adjusted and fixed, ensuring that the solar panel 10 can maintain an angle with sufficient sunlight reception.

[0034] Please refer to Figure 7 , a groove is formed in the middle of the top end of the upper support plate 12. The bottom end of the adjusting support plate 17 is arranged in the groove at the top of the upper support plate 12. Through the adjusting support plate 17, it can be completely wound into the groove. At the same time, the support for the lower support plate 13 is cancelled, so that the solar panel 10 can be laid flat above the cross beam frame plate 4, facilitating the operator to carry and install.

[0035] Please continue to refer to Figure 1 - Figure 3 , a positioning support frame plate 7 is rotatably connected to one side of the cross beam frame plate 4 away from the balance block 2. The positioning support frame plate 7 is located outside the cross beam frame plate 4. The opening of the positioning support frame plate 7 faces upward. A movable support frame plate 8 is movably sleeved in the positioning support frame plate 7. The bottom end of the movable support frame plate 8 is clamped with a support block 9 arranged at the bottom of the limit sleeve 1. A limiting device 18 is arranged at the bottom of the positioning support frame plate 7 on the side away from the cross beam frame plate 4. After the movable support frame plate 8 is clamped with the support block 9, the limiting device 18 limits the upward movement of the movable support frame plate 8 along the inclined upward direction of the cross beam frame plate 4, thereby ensuring that the limit sleeve 1, the cross beam frame plate 4, the positioning support frame plate 7 and the movable support frame plate 8 form a triangular support structure to support the solar panel 10, making the solar street lamp stable after installation and use.

[0036] Please refer to Figure 8, the limiting device 18 includes a limiting box 181 fixedly installed at the bottom of the positioning support frame plate 7. A piston plate 182 is movably sleeved inside the limiting box 181. One side of the piston plate 182 facing the positioning support frame plate 7 is fixedly connected with a baffle plate 183. One end of the baffle plate 183 extends to the inside of the positioning support frame plate 7 and is movably connected with one end of the moving support frame plate 8. The other side of the piston plate 182 is fixedly connected with a pull shaft 184. One end of the pull shaft 184 away from the piston plate 182 extends to the outside of the limiting box 181 and is fixedly connected with a pull ring, which is convenient for the operator to pull out the pull ring, thereby pulling the pull shaft 184 to move. Springs are arranged on both sides of the pull shaft 184 between the piston plate 182 and the side of the limiting box 181 away from the positioning support frame plate 7. By using the elastic force of the springs, the baffle plate 183 is kept in a state of clamping the moving support frame plate 8.

[0037] Please refer to Figure 6 and Figure 8 , chute 701 is provided on the inner walls of both sides of the positioning support frame plate 7. Please refer to Figure 2 , protrusions 801 are provided on both sides of the moving support frame plate 8. The protrusions 801 are movably sleeved with the chute 701. By limiting the protrusions 801 by the chute 701, it is ensured that the moving support frame plate 8 can move stably along the positioning support frame plate 7.

[0038] Please refer to Figure 6 and Figure 9 , a passive gear ring 26 is movably sleeved outside the positioning vertical pipe 25. A pressure ring 27 is movably connected to the top of the passive gear ring 26, and the pressure ring 27 is movably sleeved outside the positioning vertical pipe 25. An adjusting nut 28 is threadedly sleeved on the positioning vertical pipe 25. A limiting gear ring 29 located inside the passive gear ring 26 is fixedly connected to the top of the lower support plate 11. Please refer to Figure 10 , the outer cross-section of the positioning vertical pipe 25 is hexagonal, and the outer wall of the positioning vertical pipe 25 is in contact with the inner wall of the passive gear ring 26. The outer teeth of the passive gear ring 26 are engaged with the inner teeth of the limiting gear ring 29. By moving the passive gear ring 26 upward to separate it from the limiting gear ring 29, the lower support plate 11 can be rotated, and thus the angle of the solar panel 10 in the horizontal direction can be adjusted. Then, by moving the passive gear ring 26 downward, the outer teeth of the passive gear ring 26 are re-engaged with the inner teeth of the limiting gear ring 29, so as to achieve the effect of fixing the solar panel 10 at any angle in the horizontal direction after adjustment.

[0039] Please refer to Figure 1 - Figure 3, the opening of the crossbeam frame plate 4 faces downward, and ventilation slots 401 are provided on both sides of the crossbeam frame plate 4 away from one end of the box body 5. Through the opening of the ventilation slots 401, it is convenient for heat dissipation inside the crossbeam frame plate 4. At the same time, the opening position of the ventilation slots 401 is located at one end away from the box body 5. Thus, when a heat dissipation slot is opened on the box body 5 inside the crossbeam frame plate 4, while facilitating heat dissipation of the box body 5, it can ensure that rainwater will not seep into the box body 5, effectively preventing damage to electronic components inside the box body 5 due to the seepage of rainwater. Please refer to Figure 3 and Figure 9 , a wiring box 402 is fixedly connected to the bottom of the inner cavity of the crossbeam frame plate 4. The outer width value of the wiring box 402 is smaller than the inner width value of the movable support frame plate 8, ensuring that when folded, the movable support frame plate 8 can be retracted into the crossbeam frame plate 4. At the same time, the wires on the solar panel 10 are connected to the inside of the box body 5 through the positioning vertical pipe 25 and the wiring box 402.

[0040] Before the LED solar street lamp is used, the crossbeam frame plate 4 and the limit sleeve 1 are placed horizontally, and the movable support frame plate 8 is retracted into the positioning support frame plate 7, and the positioning support frame plate 7 is retracted into the crossbeam frame plate 4. After the construction personnel carry the whole LED solar street lamp and climb to the top of the lamp post 24, the insertion pipe 19 is inserted from the top of the lamp post 24. Then, rotate the balance block 2 and the limit sleeve 1 so that one side of the crossbeam frame plate 4 on the balance block 2 faces the road surface. Then, rotate the adjusting rotating plate 23 to drive the adjusting screw shaft 22 to move upward, so that one side of the pressing block 20 closely adheres to the inner wall of the lamp post 24. After the inner wall of the rubber friction sleeve 3 is tightly fitted and fixed with the outer side of the lamp post 24, rotate the crossbeam frame plate 4 to the horizontal state, and rotate the positioning support frame plate 7 to pull out the movable support frame plate 8 so that one end of the movable support frame plate 8 is clamped on the support block 9, and fix the movable support frame plate 8 through the limiting device 18. Then, prop up the two lower support plates 13, and fix one of the lower support plates 13 through the adjusting support plate 17, that is Figure 7 the adjusting support plate 17 on the top left of the middle and upper support plate 12 first fixes the lower support plate 13, then adjusts the angles of the upper support plate 14 and the lower support plate 13 on the other side to adjust the longitudinal deflection angle of the solar panel 10, and then rotate the adjusting support plate 17 on the other side of the upper support plate 12 to fix the lower support plate 13 so that the solar panel 10 maintains a fixed state of being supported. Finally, rotate the upper support plate 12 so that the inclined surface of the solar panel 10 faces south to ensure that the solar panel 10 receives sunlight for a long enough time, and that's it.
