Description

Technical Field

[0001] This invention belongs to the field of LED street light technology, specifically an energy-saving solar LED street light. Background Technology

[0002] LED streetlights are lighting devices that use light-emitting diodes as the light source. They have advantages such as energy efficiency, long lifespan, environmental friendliness, high luminous efficacy, and low maintenance costs. They are widely used in lighting urban roads, highways, parks, and public places. In recent years, with technological advancements and cost reductions, LED streetlights have become increasingly popular.

[0003] In existing technologies, LED streetlights can be mainly divided into several types, including conventional road lights, high-mast lights, tunnel lights, solar streetlights, courtyard lights, and landscape lights. Among them, high-mast lights typically refer to large lighting devices with a height of over 15 meters. They are mainly suitable for open environments that require large-scale, highly uniform lighting, such as large transportation hubs, ports, railway stations, stadiums, and large squares. This is because high-mast lights raise the light source to an extremely high position, and each individual light on it can cover a very wide area, effectively reducing the number of ground support columns and avoiding visual clutter. At the same time, its top-down lighting method can significantly reduce glare and provide a uniform and soft light environment, making it very suitable for large venues with dense traffic and high requirements for lighting quality and safety.

[0004] In the aforementioned technologies, high-mast lights, due to their height, often require the use of lifting devices for assembly. The most common lifting device is to use a winch and traction rope to raise and lower the light frame. However, since the support columns are often designed with a large bottom diameter and a small top diameter, and the inner diameter of the light frame is larger than that of the support columns, when the light frame is hoisted to a high altitude, it is very easy for the light frame to sway due to the wind, which can cause it to collide with the support columns, resulting in damage to the light frame or the support columns and increasing the difficulty of assembly.

[0005] Therefore, the present invention provides an energy-saving solar LED street light. Summary of the Invention

[0012] Preferably, the locking device includes a third gear; the top of the connecting rod passes through the connecting seat, and the top of the connecting rod is fixedly connected to the third gear; the outer sides of the third gear are meshed with a toothed ring, and the toothed ring is rotatably connected to the support column; a pair of positioning holes are opened on the surface of the connecting ring, and the included angle between the two positioning holes and the center of the toothed ring is 90 degrees; a pin is slidably connected to the top of the toothed ring on the surface of the support column, and the pin is adapted to the positioning hole.

Thus, when the first gear is engaged with the abutment plate, after the user turns the handle to move the abutment plate away from the support column, the abutment plate can remain in this state. At this time, the user can free up his hand to rotate the other handle, so that one person can complete the adjustment of the two pairs of abutment plates. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown in the embodiment of the present invention, an energy-saving solar LED street light includes a support column 1; the support column 1 is a hollow structure, and the diameter of the bottom of the support column 1 is larger than the diameter of its top; a support frame 2 is sleeved on the outside of the support column 1, and the support frame 2 is arranged in a ring; multiple lamp heads 3 are evenly arranged around the support frame 2; a support plate 4 is fixedly connected to the top surface of the support column 1; four pairs of evenly arranged fixed pulleys 5 are rotatably connected to the top surface of the support plate 4; two pairs of traction ropes 6 are fixedly connected to the top surface of the support frame 2 by hooks; a winch assembly is installed at the bottom of the support frame 2, and the winch assembly is used to wind up the traction ropes 6; multiple evenly arranged connecting boxes 7 are fixedly connected to the bottom of the support frame 2; a stop plate 8 is slidably connected to the side of the connecting box 7 near the support column 1; a pair of springs 9 are fixedly connected between the stop plate 8 and the connecting box 7; a guide wheel 10 is installed at the end of the stop plate 8 near the support column 1; a photovoltaic panel 11 is installed at the top of the support column 1; During the assembly and installation of high-mast streetlights, to prevent damage to the photovoltaic panel 11 or internal circuitry caused by impacts during hoisting, this embodiment of the invention can be used. In this embodiment, when hoisting the support frame 2 and the lamp head 3 on it to the top of the support column 1, the hoisting assembly will lift the support frame 2 through the pull rope and the paired fixed pulleys 5 on the top surface of the support plate 4. During the ascent of the support frame 2, the abutment plate 8 inside the connecting box 7 will press the guide wheel 10 at the end of the abutment plate 8 against the surface of the support column 1 under the compression of the spring 9. Since the number of abutment plates 8 is even and the elasticity of the springs 9 is consistent, it can be ensured that the inner side of the support frame 2 will not collide with the surface of the support column 1. This reduces the risk of the support frame 2 colliding with the support column 1 due to slippage caused by the ambient wind when hoisted to a high altitude, which could lead to damage to the support frame 2 and the photovoltaic panel 11. At the same time, the photovoltaic panel 11 at the top can also provide power to the lamp head 3, thereby achieving an energy-saving effect.

[0023] like Figures 3 to 5As shown, both sides of the connecting box 7 are provided with sliding grooves 12; sliders 13 are slidably connected in the sliding grooves 12; rotating rods 14 are rotatably connected between the sliders 13; gear 15 is fixedly connected to the rotating rod 14 inside the connecting box 7, and gear 15 can mesh with the bottom surface of the abutment plate 8; transmission plates 16 are fixedly connected to the sides of the two sliders 13 that are far apart from each other; the top surface of the transmission plate 16 is slidably connected to the support frame 2; connecting rings 17 are installed on the top surfaces of the pairs of transmission plates 16; during operation, when the support frame 2 is hoisted, the support frame 2 will initially be located at the bottom of the support column 1, at which time the diameter of the support column 1 is the largest. In order to facilitate the support frame 2 to be smoothly fitted onto the outside of the support column 1, the user needs to lift the connecting rings 17. Pull the transmission plate 16, which in turn drives the slider 13 in the slide groove 12 to move towards the abutment plate 8. This causes the gear 15 between the sliders 13 to mesh with the abutment plate 8. Then, the user rotates the rotating rod 14. The rotating rod 14 drives the abutment plate 8 away from the support column 1 through the gear and stretches the spring 9. This makes it easier for the user to put the support frame 2 on the surface of the support rod 36. After the support frame 2 is put on the surface of the support column 1, the user releases the connecting ring 17. Under the action of gravity, the connecting ring 17 drives the slider 13 and the gear 15 away from the abutment plate 8 through the transmission plate 16. This causes the gear 15 to disengage from the base plate, and the stretched spring 9 to recover. This causes the abutment plate 8 and its end guide wheel 10 to press against the surface of the support column 1 again.

[0024] like Figure 3 and Figure 6 As shown, the connecting ring 17 is rotatably connected to the top surface of the transmission plate 16; a plurality of evenly arranged rollers 18 are rotatably connected to the bottom surface of the connecting ring 17; a plurality of evenly arranged support seats 19 are fixedly connected to the top surface of the support frame 2 at the bottom of the connecting ring 17; the support seats 19 are arc-shaped and located between two adjacent rollers 18; during operation, when the user needs to pull the connecting ring 17 so that the gear 15 can engage with the plate 8, the user needs to rotate the connecting ring 17 and make the rollers 18 on the surface of the connecting ring 17 move along the surface of the support seat 19 to the top surface of the support seat 19. At this time, the connecting ring 17 will be lifted by the support seat 19, thereby driving the gear 15 to engage with the base plate through the transmission plate 16, the slider 13 and the rotating rod 14. Thus, the user does not need to keep pulling the rotating ring, which makes it convenient for the user to rotate the rotating rod 14.

[0025] like Figures 4 to 5As shown, one end of the rotating rod 14 is fixedly connected to a gear 20; the surface of the gear 20 is meshed with a worm gear 21; a mounting box 22 is provided at the bottom of the support frame 2 at the corresponding position of the worm gear 21; both the worm gear 21 and the gear 20 are rotatably connected inside the mounting box 22, and the bottom of the worm gear 21 extends to the outside of the mounting box 22; the mounting box 22 is fixedly connected to the connecting box; a handle 23 is fixedly connected to the bottom surface of the worm gear 21; during operation, when the user needs to rotate the rotating rod 14, the user needs to rotate the handle 23, and the handle 23 will drive the worm gear 21 inside the mounting box 22 to rotate, and the worm gear 21 will then drive the gear meshing with it to rotate. The gear 20 rotates, which in turn drives the rotating rod 14 to rotate. Since the transmission between the worm 21 and the gear 20 is unidirectional, meaning that only the worm 21 can drive the gear 20 to rotate, while the gear 20 cannot drive the worm 21, the engagement between the worm 21 and the gear 20 also acts as a lock. This allows the gear 15 to engage with the abutment 8. When the user rotates the handle 23 to move the abutment 8 away from the support column 1, the abutment 8 can remain in this state. At this time, the user can free up their hand to rotate the other handle 23, thus allowing one person to adjust both pairs of abutments 8.

[0026] like Figure 1 and Figure 7 As shown, the bottom of the support column 1 is fixedly connected to a plurality of evenly arranged connecting seats 24; a connecting rod 25 is rotatably connected between pairs of connecting seats 24; a support plate 26 is fixedly connected to the surface of each connecting rod 25; the support plate 26 is arc-shaped; a locking device is installed on the top of the support plate 26 to lock the rotation angle of the support plate 26; during operation, before hoisting the user, the user needs to rotate the support plate 26 in a direction away from the support column 1, and then the support frame 2 can be placed on the surface of the support column 1, so that the user can easily fix the traction rope 6 to the support frame 2. During transportation, the user can also fasten the support plate 26 back to the surface of the support column 1, thereby avoiding the problem of the protruding support plate 26 being easily hooked.

[0027] like Figure 7As shown, the locking device includes a gear 27; the top of the connecting rod 25 passes through the connecting seat 24, and the top of the connecting rod 25 is fixedly connected to the gear 27; the outer sides of the gear 27 are meshed with a toothed ring 28, and the toothed ring 28 is rotatably connected to the support column 1; a pair of positioning holes 29 are provided on the surface of the connecting ring 17, and the included angle between the two positioning holes 29 and the center of the toothed ring 28 is 90 degrees; a pin 30 is slidably connected to the top of the toothed ring 28 on the surface of the support column 1, and the pin 30 is adapted to the positioning holes 29; during operation, when the user rotates one of the support plates 26, the support plate 26 will drive the connecting rod 25 to rotate synchronously with it. The connecting rod 25 will drive the gear 27 on it to rotate together. Since the gear 27 is meshed with the gear ring 28, the rotating gear 27 will drive the gear ring 28 to rotate. The rotating gear ring 28 will drive the other gears 27 to rotate together. The other gears 27 can then drive the other support plates 26 to rotate synchronously through the connecting rod 25. Thus, the user only needs to rotate one of the support plates 26, and the other support plates 26 can be opened synchronously. Then, the user can insert the pin 30 into the positioning hole 29 to restrict the rotation of the gear ring 28, thereby synchronously restricting the rotation of the gear 27, the connecting rod 25 and the support plate 26.

[0028] like Figure 1 and Figure 8 As shown, the winch assembly includes a winch 31; the winch 31 is fixedly connected to the bottom of the support column 1, and an inspection door is installed on the surface of the support column 1 at the corresponding position of the winch 31; the end of the steel rope of the winch 31 is fixedly connected to a connecting disc 32; the traction rope 6 is fixedly connected around the connecting disc 32; during operation, when the user is lifting the support frame 2, the user only needs to pull the connecting disc 32 down by the winch 31, and then pull each traction rope 6 down by the connecting plate 40, and then change the direction of the tension in the traction rope 6 by the pair of fixed pulleys 5, thereby driving the support frame 2 to rise. Since the steel rope of the winch 31 only needs to be connected to one connecting disc 32, the problem of the traction rope 6 easily getting tangled is avoided, which is caused by multiple tractions being wound by one winch 31.

[0029] like Figure 1 and Figure 7As shown, the outer surface of the toothed ring 28 is provided with a plurality of grooves 33, which are adapted to the traction rope 6; the surface of the support plate 26 is provided with insertion holes 34, which are adapted to the hooks at the ends of the traction rope 6; the surface of the support column 1 is fixedly connected with a stop block 35 at the corresponding position of the insertion hole 34; during operation, in the process of transporting the embodiment of the present invention, the user can pass the end of the traction rope 6 away from the connecting plate 32 through the groove 33 and the insertion hole 34 on the surface of the support plate 26, and then fasten the support plate 26 to the support column 1. At this time, the support plate 26 and the stop block 35 will clamp the end of the traction rope 6 away from the connecting plate 32, thereby avoiding the problem of the traction rope 6 getting tangled during the process, and also avoiding the problem of the traction rope 6 being completely drawn into the support column 1, thus facilitating the subsequent hoisting operation.

[0030] like Figure 1 and Figure 9 As shown, the top surface of the support plate 4 is fixedly connected to a pair of fixed pulleys 5 with support rods 36; the top surfaces of the support rods 36 are all fixedly connected to a cover 37; the diameter of the cover 37 is larger than that of the support plate 4, and the top is arc-shaped; the photovoltaic panel 11 is fixedly connected to the surface of the cover 37 by a bracket; a straight rod 38 is fixedly connected to the bottom surface of the cover 37; a magnet 39 is fixedly connected to the end of the straight rod 38 away from the cover 37; the connecting plate 32 is made of magnetizable metal; during operation, after the support column 1 is erected on the ground, the magnet 39 at the bottom of the straight rod 38 will attract the column connecting plate 32 and place it at the top of the support column 1. At this time, the connecting plate 32 will not slip to the bottom of the support column 1 due to its own weight, thereby causing the traction rope 6 to be pulled into the support column 1, which makes it convenient for the user to fix the traction rope 6 to the support frame 2.

[0031] like Figures 1 to 2As shown, two pairs of evenly arranged connecting plates 40 are fixedly connected to the top of the support column 1; hooks 41 are rotatably connected to the surface of each connecting plate 40 and fixedly connected to the surface of a rotating column, with the rotating column located at the top of the hooks 41; the center of gravity of each hook 41 is located at its bottom, and the edges of each hook 41 are arc-shaped; a support ring 42 is fixedly connected inside the support frame 2; during operation, when the support frame 2 rises to the top of the support column 1, the inner support ring 42 touches the bottom inclined surface of the hook 41, thereby causing the hook 41 to rotate. When the support ring 42 rises to the center position of the hook 41, the deflected hook 41 will naturally fall back to its original position. At this time, the support frame 2 descends, causing the support ring 42 to rotate. 42 lands precisely on the hanging hook 41, completing the hooking process. When unhooking, the support frame 2 continues to rise until the height of the support ring exceeds the height of the hook 41. Then, the support frame 2 drives the support ring to descend. During this process, the support ring will squeeze the upper end of the hook 41, and as the support ring descends, the hook 41 will be forced to rotate 360°. At this point, the hook 41 ring of the support frame 2 is completely detached from the hook 41 range, and the unhooking is successful. Thus, by supporting the support ring with the hook 41, it is possible to prevent the traction rope 6 from breaking due to corrosion and causing the support frame 2 to fall. It is also possible to unlock the support ring with the hook 41 without adding an additional power source, which is convenient for users to carry out future inspection and maintenance.

[0032] During operation, when assembling and installing high-mast streetlights, to prevent damage to the photovoltaic panel 11 or internal circuitry caused by impacts during hoisting, this embodiment of the invention can be used. In this embodiment, when hoisting the support frame 2 and the lamp head 3 on it to the top of the support column 1, the hoisting assembly will lift the support frame 2 through the pull rope and the paired fixed pulleys 5 on the top surface of the support plate 4. During the ascent of the support frame 2, the abutment plate 8 inside the connecting box 7 will press the guide wheel 10 at the end of the abutment plate 8 against the surface of the support column 1 under the compression of the spring 9. Since the number of abutment plates 8 is even and the elasticity of the springs 9 is consistent, it can be ensured that the inner side of the support frame 2 will not collide with the surface of the support column 1. This reduces the risk of the support frame 2 colliding with the support column 1 due to slippage caused by the ambient wind when hoisted to a high altitude, which could lead to damage to the support frame 2 and the photovoltaic panel 11. At the same time, the photovoltaic panel 11 at the top can also provide power to the lamp head 3, thereby achieving an energy-saving effect.

[0033] When hoisting the support frame 2, it will initially be located at the bottom of the support column 1, at which point the diameter of the support column 1 is at its maximum. To facilitate the smooth mounting of the support frame 2 onto the outside of the support column 1, the user needs to pull the connecting ring 17. The connecting ring 17 pulls the transmission plate 16, which in turn drives the slider 13 in the slide groove 12 to move towards the abutment plate 8. This causes the gear 15 between the sliders 13 to mesh with the abutment plate 8. Afterward, the user rotates the rotating rod 14, which, through the gear, drives the abutment plate 8. The support frame 2 moves away from the support column 1 and stretches the spring 9, making it easier for the user to put the support frame 2 on the surface of the support rod 36. After the support frame 2 is put on the surface of the support column 1, the user releases the connecting ring 17. Under the action of gravity, the connecting ring 17 drives the slider 13 and the gear 15 to move away from the abutment plate 8 through the transmission plate 16. This causes the gear 15 to disengage from the base plate, the stretched spring 9 returns to its original position, and then drives the abutment plate 8 and its end guide wheel 10 to press against the surface of the support column 1 again.

[0034] When the user needs to pull the connecting ring 17 so that the gear 15 can engage with the plate 8, the user needs to rotate the connecting ring 17 and make the roller 18 on the surface of the connecting ring 17 move along the surface of the support base 19 to the top surface of the support base 19. At this time, the connecting ring 17 will be lifted by the support base 19, thereby driving the gear 15 to engage with the base plate through the transmission plate 16, the slider 13 and the rotating rod 14. Thus, the user does not need to keep pulling the rotating ring, which makes it convenient for the user to rotate the rotating rod 14.

[0035] When the user needs to rotate the rotating rod 14, the user needs to rotate the handle 23, which in turn drives the worm gear 21 in the mounting box 22 to rotate. The worm gear 21 then drives the gear 20 that meshes with it to rotate, and finally the gear 20 drives the rotating rod 14 to rotate. Since the transmission between the worm gear 21 and the gear 20 is unidirectional, that is, only the worm gear 21 can drive the gear 20 to rotate, while the gear 20 cannot drive the worm gear 21 to rotate, the cooperation between the worm gear 21 and the gear 20 can also play a locking role. Thus, when the gear 15 is engaged with the abutment plate 8, after the user rotates the handle 23 to move the abutment plate 8 away from the support column 1, the abutment plate 8 can remain in this state. At this time, the user can free up his hand to rotate the other handle 23, so that one person can complete the adjustment of the two pairs of abutment plates 8.

[0036] Before hoisting the user, the user needs to rotate the support plate 26 away from the support column 1. Then the support frame 2 can be placed on the surface of the support column 1, which makes it easy for the user to fix the traction rope 6 to the support frame 2. During transportation, the user can also fasten the support plate 26 back to the surface of the support column 1 to avoid the problem of the protruding support plate 26 being easily hooked.

[0037] When the user rotates one of the support plates 26, the support plate 26 will drive the connecting rod 25 to rotate synchronously, and the connecting rod 25 will drive the gear 27 on it to rotate together. Since the gear 27 is meshed with the gear ring 28, the rotating gear 27 will drive the gear ring 28 to rotate, and the rotating gear ring 28 will drive the remaining gears 27 to rotate together. The remaining gears 27 can then drive the remaining support plates 26 to rotate synchronously through the connecting rod 25. Thus, the user only needs to rotate one of the support plates 26, and the remaining support plates 26 can be opened synchronously. Then, the user can insert the pin 30 into the positioning hole 29 to restrict the rotation of the gear ring 28, thereby synchronously restricting the rotation of the gear 27, the connecting rod 25 and the support plate 26.

[0038] When the user is lifting the support frame 2, the user only needs to pull the connecting plate 32 down by the winch 31, and then pull each traction rope 6 down by the connecting plate 40. Then, the direction of the tension in the traction rope 6 is changed by the pair of fixed pulleys 5, thereby driving the support frame 2 up. Since the steel rope of the winch 31 only needs to be connected to one connecting plate 32, the problem of the traction rope 6 being easily tangled is avoided, which is caused by multiple tractions being wound by one winch 31.

[0039] During the transportation of this embodiment of the invention, the user can pass the end of the traction rope 6 away from the connecting plate 32 through the groove 33 and the insertion hole 34 on the surface of the support plate 26, and then fasten the support plate 26 to the support column 1. At this time, the support plate 26 and the abutment block 35 will clamp the end of the traction rope 6 away from the connecting plate 32, thereby avoiding the problem of the traction rope 6 getting tangled during the process, and also avoiding the problem of the traction rope 6 being completely drawn into the support column 1, thus facilitating the subsequent hoisting operation.

[0040] After the support column 1 is erected on the ground, the magnet 39 at the bottom of the straight rod 38 will attract the column connecting plate 32 and place it at the top of the support column 1. At this time, the connecting plate 32 will not slip to the bottom of the support column 1 due to its own weight, which will cause the traction rope 6 to be pulled into the support column 1, thus making it easier for the user to fix the traction rope 6 to the support frame 2.

[0041] When the support frame 2 rises to the top of the support column 1, its inner support ring 42 touches the bottom slope of the hook 41, thereby causing the hook 41 to rotate. When the support ring 42 rises to the center position of the hook 41, the deflected hook 41 will naturally fall back to its original position. At this time, the support frame 2 descends, and the support ring 42 falls exactly on the falling hook 41 to complete the hooking. To unhook, the support frame 2 continues to rise until the height of the support ring exceeds the height of the hook 41. Then the support frame 2 drives the support ring to descend. During this process, the support ring will squeeze the upper end of the hook 41, and as the support ring descends, the hook 41 will be forced to rotate 360°. At this time, the hook ring of the support frame 2 is completely separated from the hook 41 and successfully unhooked. Thus, by supporting the support ring with the hook 41, it is not only possible to prevent the traction rope 6 from breaking due to corrosion and causing the support frame 2 to fall, but also to unlock the support ring with the hook 41 without adding an additional power source, which is convenient for users to carry out future maintenance.
