[0035] Embodiment 1:

[0036] See also Figure 1-Figure 3 As shown, an adjustable intelligent LED lighting street lamp includes a support column 1, an LED lamp housing 2 and an LED lamp bead 3. The LED lamp housing 2 is arranged at the top of the support column 1, and the LED lamp housing 2 is fixed to the top of the support column 1. The LED lamp bead 3 is arranged on the bottom surface of the LED lamp housing 2. The LED lamp bead 3 is embedded and installed at the bottom end of the inner part of the LED lamp housing 2.

[0037] See also Figure 3-Figure 5 As shown, the cylindrical surface of the rotating cylinder 44 is provided with air holes 45 and air grooves 46, and the air holes 45 are located above the air grooves 46, and air can enter the interior of the rotating cylinder 44 from the air holes 45, and enter the interior of the LED lamp housing 2 from the air grooves 46, and the area where the air holes 45 and the air grooves 46 are located is smaller than the area of ​​the reserved grooves 47, and the central angle of the air grooves 46 is less than 90°, and the position of the air holes 45 can be adjusted to adjust the opening size or closing of the ventilation channel, and the air holes 45 can prevent foreign matter from entering the interior of the LED lamp housing 2, and the air holes 45 and the air grooves 46 can also be rotated so that the air holes 45 and the air grooves 46 are staggered with the reserved grooves 47.

[0038] See also Figure 3-Figure 5 As shown, the air hole 45 is located above the top surface of the support column 1, and the air groove 46 is located below the top surface of the LED lamp housing 2. The cold air flows into the rotating cylinder 44 from above the air hole 45, and the air is discharged from the air groove 46 to the interior of the LED lamp housing 2, or the hot air is discharged from the air groove 46 and the air hole 45, thereby dissipating the hot air flow inside the LED lamp housing 2.

[0039] It should be noted that the bottom end of the support column 1 is installed on the ground, and the top end of the support column 1 is welded to the LED lamp housing 2, and the LED lamp beads 3 are installed on the inner lower surface of the LED lamp housing 2. When the LED lamp beads 3 inside the LED lamp housing 2 are working, heat is generated, so the internal heat of the LED lamp housing 2 will affect the normal operation of the LED lamp beads 3, and the inside of the LED lamp housing 2 needs to be dissipated. Specifically, the fixing tube 42 and the reserved hole 41 are interference fit, and the fixing tube 42 is clamped at the reserved hole 41 of the LED lamp housing 2 without external force. The air vent 45 of the fixing tube 42 is located above the top surface of the LED lamp housing 2. At this time, air flows in from the air vent 45. The air vents 45 and the air vents 46 are arranged on the rotating cylinder 44 so as to cool the interior of the LED lamp housing 2. The air vents 46 and the air vents 45 are arranged on the rotating cylinder 44 so as to cool the interior of the LED lamp housing 2. The air vents 46 and the air vents 45 are arranged on the rotating cylinder 44 so as to cool the interior of the LED lamp housing 2. The air vents 45 and the air vents 46 are arranged on the rotating cylinder 44 so as to cool the interior of the LED lamp housing 2.

[0040] See also Figure 2 and Figure 6 As shown, an opening and closing structure 5 for controlling the rotation of the rotating cylinder 44 is provided below the three rotating cylinders 44 of the heat dissipation assembly 4, and the opening and closing structure 5 includes a support plate 51, and three reserved holes 52 are opened inside the support plate 51, and the rotating cylinder 44 is located inside the reserved hole 52 of the support plate 51, and the rotating cylinder 44 is rotatably connected to the inside of the reserved hole 52. Since the rotating cylinder 44 and the fixed cylinder 42 are movably connected through the connecting nail 49, and the support plate 51 is located below the rotating cylinder 44, a worm gear 53 is welded to the bottom end of each rotating cylinder 44, and the axis of the worm gear 53 is adapted to the axis of the rotating cylinder 44. A connecting plate 56 is provided at the edge of the support plate 51, and a driving motor 54 is installed on the lower surface of the connecting plate 56. A worm 55 is provided at the output end of the driving motor 54. The worm 55 is meshed with three worm wheels 53, and the worm wheels 53 rotate synchronously with the rotating cylinder 44. The driving motor 54 on the connecting plate 56 is started, and the driving motor 54 drives the worm 55 to mesh with the three worm wheels 53, so that the three worm wheels 53 rotate with the rotating cylinder 44, so that the air holes 45 and the air grooves 46 can be controlled to be staggered with the reserved grooves 47, and the position of the air grooves 46 can be adjusted to adjust the opening or closing of the fixed cylinder 42.

[0041] See also Figure 6As shown, a plurality of rotating bearings 57 are provided on the lower surface of the support plate 51, and the rotating bearings 57 are located between the rotating cylinders 44. Each rotating bearing 57 is rotatably connected to the worm 55, and the worm 55 can be supported by the rotating bearing 57 to prevent the worm 55 from bending and causing the worm 55 to be unable to mesh with the worm wheel 53. The rotation angle of each rotating cylinder 44 is 90°, and the worm wheel 53 can be driven to rotate by the worm 55. The rotation of the rotating cylinder 44 can stagger or overlap the air holes 45 and the air grooves 46 with the reserved grooves 47.

[0042] It should be noted that, since the fixed cylinder 42 is engaged with the inside of the reserved hole 41, the rotating cylinder 44 can be initially placed inside the fixed cylinder 42. When the rotating cylinder 44 needs to be automatically rotated, the driving motor 54 can be started. The rotation of the driving motor 54 can drive the worm 55 to mesh with the three worm gears 53. The three rotating cylinders 44 rotate along with the worm gears 53, thereby rotating the rotating cylinders 44 inside their respective fixed cylinders 42 until the air holes 45 and the air grooves 46 of the rotating cylinders 44 are rotated. The rotating cylinders 44 can be rotated according to the needs. The areas of the air holes 45 and the air grooves 46 are aligned with or staggered with the areas of the reserved grooves 47. When the air holes 45 and the air grooves 46 are aligned with the reserved grooves 47, the cold air flow and the hot air flow can exchange the LED lamp housing 2 through the rotating cylinder 44, which is beneficial to the heat inside the LED lamp housing 2 to be dissipated. When the air holes 45 and the air grooves 46 are staggered with the reserved grooves 47, foreign matter can be blocked from entering the interior of the LED lamp housing 2 from the reserved grooves 47, and there is no need to manually rotate the rotating cylinder 44, which is more convenient.

[0043] See also Figure 2 , Figure 6 and Figure 7As shown, two sets of lifting structures 6 are arranged below the support plate 51 and at the rotating cylinder 44 in the middle. The lifting structure 6 includes teeth 61, and the teeth 61 are opened at the bottom edge of the rotating cylinder 44. A fixing box 63 is welded below the support plate 51, and a gear 64 is arranged inside the fixing box 63. The gears 64 of the two lifting structures 6 are meshed with the teeth 61. The rotating cylinder 44 driven by the worm 55 will cause the teeth 61 to rotate, so that the teeth 61 of the rotating cylinder 44 and the gear 64 rotate. A guide block 65 is arranged in the middle of the gear 64, and a screw rod 62 is arranged in the middle of the gear 64, and the screw rod 62 passes through the support plate 51 and the fixing box 63. 3, the screw rod 62 is threadedly connected with the support plate 51, and the side wall of the screw rod 62 is provided with a guide groove 66, which is matched with the guide block 65. The rotating gear 64 drives the screw rod 62 to rotate, so that the screw rod 62 is threadedly connected with the support plate 51 so that the support plate 51 is lifted and lowered, and the heat dissipation component 4 and the opening and closing structure 5 on the support plate 51 are synchronously moved up and down, the guide block 65 of the gear 64 is slidably connected with the guide groove 66 of the screw rod 62, and the gear 64 is rotatably connected with the inside of the fixed box 63. When the support plate 51 is located at the time when the screw rod 62 is lifted and lowered, the gear 64 is located inside the fixed box 63 and rotates, and the gear 64 is restricted inside the fixed box 63.

[0044] See also Figure 7-Figure 9 As shown, a connecting plate 2 67 is welded to the inner wall of the LED lamp housing 2, and a rotating bearing 2 68 is arranged between the connecting plate 2 67 and the top surface of the LED lamp housing 2, and both ends of the screw rod 62 are connected to the rotating bearing 2 68, the inner diameter of the gear 64 is matched with the outer diameter of the screw rod 62, and the two ends of the screw rod 62 can rotate around the rotating bearing 2 68, and there is a gap at the intersection of the screw rod 62 and the fixed box 63.

[0045] See also Figure 8 As shown, the two gears 64 of the two lifting structures 6 are symmetrical about the axis center of the worm gear 53, and the two gears 64 rotate in the same direction, and the two gears 64 are lifted and lowered synchronously. The lifting height of the gear 64 is matched with the height of the air vent 45. Rotating the rotating cylinder 44 can drive the gear 64 and the screw 62 to rotate, so that the support plate 51 can be lifted and lowered, ensuring that the lifting height of the entire support plate 51 is the same.

[0046] It should be noted that, since the screw rod 62 is located between the end of the second connecting plate 67 and the top surface of the LED lamp housing 2, the positions of the two ends of the screw rod 62 will not change, but the screw rod 62 can rotate around the second rotating bearing 68. When the lifting structure 6 is working, the worm wheel 53 driven by the worm 55 rotates, and the worm wheel 53 in the middle position can drive the teeth 61 on the rotating cylinder 44 to rotate. The teeth 61 of the rotating cylinder 44 can drive the gears 64 of the two lifting structures 6 to rotate. The gears 64 can be lifted and lowered with the fixing box 63 of the support plate 51 without affecting the meshing of the gears 64 and the teeth 61. When the screw rod 62 rotates with the gear 64, the screw rod 62 can mesh with the support plate 51. The screw transmission is carried out so that the support plate 51 is lifted and lowered. At this time, the fixed cylinder 42 is affected by the support plate 51. When the force acting on the lifting and lowering of the fixed cylinder 42 is greater than the force acting on the fixed cylinder 42 to be clamped inside the reserved hole 41, the fixed cylinder 42 can be lifted and lowered in the reserved hole 41. During this period, the guide block 65 of the gear 64 is lifted and lowered along the guide groove 66 of the screw rod 62 to ensure that the gear 64 can rotate while being lifted and lowered, so that the heat dissipation component 4 and the opening and closing structure 5 can be lifted and lowered as a whole. The rotating cylinder 44 is raised to exchange airflow between the LED lamp housing 2 and the external air. The rotating cylinder 44 is lowered to close the fixed cylinder 42 to prevent foreign matter or rainwater from entering the interior of the LED lamp housing 2.

[0047] See also Figure 2 and Fig.10 As shown, a sealing component 7 is provided at the top of the LED lamp housing 2, and the sealing component 7 includes a boss 71. The shape of the boss 71 is adapted to the shape of the reserved hole 41, and a reserved opening 72 is opened on the upper surface of the boss 71. A sealing gasket 73 is provided inside the reserved opening 72, and the sealing gasket 73 is placed inside the reserved opening 72. The shape of the sealing gasket 73 is adapted to the shape of the fixed cylinder 42. When the fixed cylinder 42 is lowered, the fixed cylinder 42 can be in contact with the sealing gasket 73, thereby preventing rainwater from entering the reserved hole 41; the shape of the fixed cylinder 42 and the shape of the sealing gasket 73 are both "8"-shaped, and the fixed cylinder 42 covers the surface of the sealing gasket 73. The fixed cylinder 42 fits with the sealing gasket 73, and rainwater cannot enter the interior of the LED lamp housing 2, thereby preventing rainwater from entering the interior of the LED lamp housing 2 and damaging the electronic components inside the LED lamp housing 2. When the fixed cylinder 42 is separated from the boss 71, the fixed cylinder 42 can be used normally.

[0048] When the present invention is in use, the bottom end of the support column 1 is installed on the ground, and the top end of the support column 1 is welded to the LED lamp housing 2, and the LED lamp beads 3 are installed on the inner lower surface of the LED lamp housing 2. When the LED lamp beads 3 inside the LED lamp housing 2 are working, heat is generated, so that the internal heat of the LED lamp housing 2 will affect the normal operation of the LED lamp beads 3, and the inside of the LED lamp housing 2 needs to be heat-dissipated. The fixing cylinder 42 is interference-fitted with the inside of the reserved hole 41, and the connecting nail 49 is connected to the end of the intermediate shaft 48. Since the fixing cylinder 42 is fixed inside the reserved hole 41, the rotating cylinder 44 rotates inside the fixing cylinder 42, and the rotating cylinder 44 rotates relative to the intermediate shaft 48, and the rotating fan blades 43 rotate relative to the intermediate shaft 48. When the airflow is blown from the reserved groove 47 into the interior of the fixed cylinder 42 and the rotating fan blade 43 rotates, the air hole 45 can prevent foreign matter from entering the interior of the LED lamp housing 2, and the air hole 45 and the air groove 46 can be rotated so that the air hole 45 and the air groove 46 are staggered with the reserved groove 47 to prevent foreign matter from entering the interior of the fixed cylinder 42 or the LED lamp housing 2; when the fixed cylinder 42 is lowered, the fixed cylinder 42 can be brought into contact with the sealing gasket 73, thereby preventing rainwater from entering the interior of the reserved hole 41, and the fixed cylinder 42 fits with the sealing gasket 73, so that rainwater cannot enter the interior of the LED lamp housing 2, thereby preventing rainwater from entering the interior of the LED lamp housing 2 and damaging the electronic components inside the LED lamp housing 2;

[0049] Since the fixed cylinder 42 is engaged with the inside of the reserved hole 41, the rotating cylinder 44 can be initially placed inside the fixed cylinder 42. When necessary, a rain sensor module can be installed on the surface of the fixed cylinder 42. The rain sensor can be used to sense whether there is rain. After sensing rain, the module can be used to control the start of the driving motor 54. When sensing no rain, the driving motor 54 can be turned off. When it is necessary to automatically rotate the rotating cylinder 44 in rainy weather, the driving motor 54 can be started. The rotation of the driving motor 54 can drive the worm 55 to mesh with the three worm gears 53. The three rotating cylinders 44 rotate with the worm gears 53, so that the rotating cylinders 44 are rotated inside their respective fixed cylinders 42, and the air holes 45 and the air grooves 46 can be rotated relative to the reserved grooves 47. When the positions of the air holes 45 and the air grooves 46 are aligned with the reserved grooves 47, the air flow can be exchanged. The positions of the air holes 45 and the air grooves 46 and the reserved grooves 47 are staggered to prevent foreign matter from entering the LED lamp housing 2.

[0050] Since the screw rod 62 is located between the end of the second connecting plate 67 and the top surface of the LED lamp housing 2, the positions of the two ends of the screw rod 62 will not change. During this period, the screw rod 62 can rotate around the second rotating bearing 68. When the lifting structure 6 is working, the worm wheel 53 driven by the worm 55 rotates, and the worm wheel 53 in the middle position can drive the teeth 61 on the rotating cylinder 44 to rotate. The teeth 61 of the rotating cylinder 44 can drive the gears 64 of the two lifting structures 6 to rotate. The gears 64 can be lifted and lowered with the fixing box 63 of the support plate 51 without affecting the meshing of the gears 64 and the teeth 61. The screw rod 62 moves with When the gear 64 rotates, the screw rod 62 can be threadedly driven with the support plate 51. At this time, the fixed cylinder 42 is affected by the support plate 51. When the force of the support plate 51 and the screw rod 62 is greater than the force of the fixed cylinder 42 clamped inside the reserved hole 41, the fixed cylinder 42 can be lifted and lowered in the reserved hole 41. During this period, the guide block 65 of the gear 64 is lifted and lowered along the guide groove 66 of the screw rod 62 to ensure that the gear 64 can rotate while being lifted and lowered, so that the heat dissipation component 4 and the opening and closing structure 5 can be lifted and lowered as a whole. The rotating cylinder 44 is raised to exchange airflow between the LED lamp housing 2 and the external air.

[0051] The rotating cylinder 44 descends to close the fixed cylinder 42 to prevent foreign matter or rainwater from entering the interior of the LED lamp housing 2.
