A rotating cylinder 51 is provided at the top of the pile body 1, and the rotating cylinder 51 is fixedly connected to the street light cross bar 2. The inner wall of the rotating cylinder 51 is fixedly connected to a limiting cylinder 52, and a locking component 6 is provided at the bottom of the limiting cylinder 52; an overspeed unlocking component 7 is provided on the outside of the wind sensing component 4 near the bottom, and the overspeed unlocking component 7 is used to unlock the locking component 6 when the fan blade 42 reaches the set speed; a control rod 53 is provided inside the street light cross bar 2, and a driving steering component 9 is provided at the end of the control rod 53, and the driving steering component 9 is used to drive the control rod 53 to rotate adaptively when the street light cross bar 2 rotates.

[0036] The street lamp post body 1 appearing in the drawings of the present case only shows a partial structure, which represents the overall structure of the street lamp post body 1 .

[0037] Nowadays, some windy areas generally install street lamps that rely on wind power generation. The wind energy is converted into electrical energy and stored through wind energy storage equipment, and then the street lamps are powered. In order to avoid damage to the street lamp crossbar 2 when the wind is too strong, the street lamp crossbar 2 can be allowed to swing slowly with the wind within a set time period until it swings from the windward area to the leeward area, thereby reducing the contact area with the wind, and relying on the street lamp post body 1 to block the wind, thereby achieving the purpose of protecting the street lamp crossbar 2 and the street lamp head 3; not only that, in order to avoid the street lamp head 3 from deflecting the illuminated area when the street lamp crossbar 2 turns, by driving the steering component 9, it can be achieved that when the street lamp crossbar 2 rotates, the driving control rod 53 can be adaptively rotated, thereby achieving the illumination area of ​​the street lamp head 3 remains unchanged, so that even in windy weather, the street lamp can still have the same lighting effect as before.

[0038] See also Figure 4-5In an embodiment further provided by the present invention, the locking component 6 includes a first support plate 61, a first ring plate 62 is fixedly connected to the bottom of the limit cylinder 52, a plurality of first limit plates 63 are fixedly connected to the outer end of the first ring plate 62, a second ring plate 64 is fixedly connected to the top of the first support plate 61, a plurality of guide grooves 65 are provided on the second ring plate 64, a second limit plate 66 is slidably connected to the inner wall of the guide groove 65, a first reset member 67 is fixedly connected between the top of the second limit plate 66 and the inner top of the guide groove 65, and the over-speed unlocking component 7 pushes the plurality of second limit plates 66 to rise when the speed of the fan blade 42 is too fast.

[0039] By setting a plurality of first limiting plates 63 and second limiting plates 66, it can be ensured that the street light cross bar 2 can remain stationary and will not sway freely with the wind when the wind force is relatively small. When the wind force is set to be less than the first speed, the device can normally generate electricity and store energy through wind power. At this time, the street light cross bar 2 remains stationary. When the second limiting plate 66 rises, the first limiting plate 63 can rotate freely. At this time, the street light cross bar 2 can freely change its position with the wind direction until it moves to the leeward position, thereby reducing the impact of the wind on it.

[0040] See also Figure 6 In an embodiment further provided by the present invention, the overspeed unlocking component 7 includes a support rod 71 fixedly connected to the bottom of the rotating rod 41, and a toggle component 8 is arranged at the outer end of the support rod 71. The top of the first support plate 61 is rotatably connected to the third ring plate 72, and a rotation damping is arranged between the first support plate 61 and the third ring plate 72, and the damping method can be air pressure or oil pressure. The outer wall of the third ring plate 72 is fixedly connected to a rotating ring 73, and the top of the rotating ring 73 is fixedly connected to a hemispherical protrusion 74 at the top. The inner wall of the third ring plate 72 is fixedly connected to a driven gear 75. When the fan blade 42 reaches the set speed, the toggle component 8 can rotate with the driven gear 75, so that the protrusion 74 lifts the second limit plate 66. A smooth curved groove is provided at the bottom of the second limit plate 66 near one end of the protrusion 74, and a guide hole is provided on the second limit plate 66. A guide rod is provided in the guide hole, and the guide rod is fixedly connected to the inner wall of the guide groove 65, so that the second limit plate 66 can only slide up and down.

[0041] During the rotation of the swivel 73, the plurality of protrusions 74 will rotate with it. The protrusions 74 and the smooth curved grooves of the second limiting plate 66 are adapted to each other, so that the rotation of the protrusions 74 will cause the second limiting plate 66 nearby to rise, thereby helping the first limiting plate 63 to be unlocked and rotate freely.

[0042] See also Figure 7-8In the embodiment provided by the present invention, the toggle component 8 includes a driving sleeve 81 fixedly sleeved on the outer end of the support rod 71, and a movable groove 82 is opened at the outer end of the driving sleeve 81. The inner wall of the movable groove 82 is slidably connected with a toggle column 83, and the end of the toggle column 83 is fixedly connected with a toggle tooth 84. A second reset member 85 is fixedly connected between the inner wall of the movable groove 82 and the toggle column 83. When the driving sleeve 81 reaches the set speed, the centrifugal force is used to extend the toggle tooth 84 and rotate the driven gear 75. In this case, the first reset member 67 and the second reset member 85 are both compression springs.

[0043] When the rotation speed of the fan blade 42 reaches the second speed, the rotation speed is too fast. The driving sleeve 81 rotates rapidly through the rotating rod 41 and the supporting rod. Under the action of centrifugal force, the toggle column 83 overcomes the elastic force of the second reset member 85 and slides outward, so that the latching tooth is close to the driven gear 75, so that the latching tooth will also rotate with the driven gear 75 during the high-speed rotation. The driven gear 75 in turn rotates with the rotating ring 73 and the protrusion 74, helping the second limit plate 66 to rise, thereby achieving the effect of unlocking the first limit plate 63.

[0044] See also Fig. 9 In the solution further provided by the present invention, the driving steering component 9 and the street lamp post body 1 are fixedly connected with a second support plate 91, a gear shaft 92 is rotatably connected between the second support plate 91 and the first support plate 61, and an outer end of the gear shaft 92 is fixedly sleeved with an axis gear 93, and a first annular groove 94 and a second annular groove 95 are respectively provided on the top of the second support plate 91, and a third annular groove is provided on the bottom of the first support plate 61, and a first gear rod 96 is rotatably connected between the first annular groove 94 and the third annular groove, and a driving wheel 97 is fixedly sleeved on the outer wall of the first gear rod 96, and the limit A rotating hole is opened on the position tube 52, and the inner wall of the rotating hole is rotatably connected to the second gear rod 98, and the bottom of the gear rod extends to the inside of the second annular groove 95. The outer end of the second gear rod 98 near the top is fixedly sleeved with a first bevel gear 99, and the end of the control rod 53 is fixedly connected to a third gear rod 910, and the end of the third gear rod 910 is fixedly sleeved with a second bevel gear 911. The first bevel gear 99 is meshingly connected with the second bevel gear 911. When the second gear rod 98 rotates around the axis gear 93, it drives the second bevel gear 911 to rotate, so as to adaptively adjust the illumination angle of the street lamp head 3.

[0045] The outer ends of the gear shaft 92, the first gear rod 96 and the second gear rod 98 are movably sleeved with a first sleeve 912, a second sleeve 913 and a third sleeve 914 respectively, a first transmission rod 915 is fixedly connected between the first sleeve 912 and the second sleeve 913, a second transmission rod 916 is fixedly connected between the second sleeve 913 and the third sleeve 914, and limiting rings are arranged on the upper and lower parts of the first sleeve 912, the second sleeve 913 and the third sleeve 914.

[0046] When the first limiting plate 63 is separated from the second limiting plate 66, the clamping of the first limiting plate 63 is lost, and the street light crossbar 2 will rotate with the wind force. At this time, the rotating cylinder 51 rotates with the limiting cylinder 52, and the limiting cylinder 52 rotates with the first gear rod 96 through the second gear rod 98, the first transmission rod 915 and the second transmission rod 916. Since the shaft gear 93 is fixed and the driving wheel 97 rotates around the shaft gear 93, the driving wheel 97 can rotate around the shaft gear 93 and at the same time rotate on its own. By meshing with the driven wheel, the force is transmitted to the second gear rod 98, so that the second gear rod 98 can also rotate around the shaft gear 93 and at the same time rotate on its own. Taking the bird's-eye view as an example, initially, the street light crossbar 2 is in the east direction. When the street light crossbar 2 rotates clockwise, the driving wheel 97 also rotates clockwise, and the driven wheel rotates counterclockwise. Since the first bevel gear 99 is meshed with the second bevel gear 911, the control rod 53 rotates counterclockwise from the right side perspective; when the street light crossbar 2 rotates toward the south (still from a bird's-eye view), the street light head 3 rotates toward the north, thereby adaptively compensating the illumination angle of the street light head 3 to ensure that the illumination area of ​​the street light head 3 will not change due to the street light crossbar 2 turning to avoid the wind.

[0047] See also Fig.11 In a solution further provided by the present invention, a buffer component 10 is also provided at the bottom of the limiting cylinder 52, and the buffer component 10 includes a third support plate 101 fixedly connected to the inner wall of the street lamp post body 1, and a buffer box 102 is fixedly connected to the top of the third support plate 101, and an annular sealing plate 103 is rotatably connected to the inner wall of the buffer box 102. An annular hole 104 is provided on the top of the buffer box 102, and a ring connecting plate 105 is fixedly connected between the annular sealing plate 103 and the limiting cylinder 52. A buffer plate 106 is fixedly connected to the bottom of the annular sealing plate 103, and a limiting flow hole 107 is provided on the buffer plate 106. The interior of the buffer box 102 is filled with liquid, and the liquid can be water or hydraulic oil.

[0048] In order to prevent the street light cross bar 2 from rotating too fast due to strong wind, causing the street light cross bar 2 to continue rotating under inertia when the wind stops, a buffer plate 106 can be set to make it rotate in the liquid, thereby providing appropriate resistance for the street light cross bar 2 during rotation. Not only can the liquid pressure be used to consume wind force and reduce the impact force caused by the wind, but it can also effectively prevent the street light cross bar 2 from continuing to rotate under the action of inertia when the wind stops.

[0049] See also Fig.10 In a solution further provided by the present invention, a manual unlocking component 11 is further provided at the bottom of the rotating rod 41, and the manual unlocking component 11 includes a touch rod 111 rotatably connected to the bottom of the rotating rod 41, and the bottom end of the touch rod 111 successively moves through the limiting cylinder 52 and the driving sleeve 81, and extends to the inside of the movable groove 82, and the bottom of the touch rod 111 is fixedly connected to a pushing block 112, and the top of the toggle column 83 is provided with an inclined groove 113, and the bottom of the pushing block 112 is in an inclined shape, and when the rotating rod 41 moves downward, the latch tooth extends.

[0050] After each period of strong winds, maintenance personnel will come to check. By pressing the rotating rod 41, the touch rod 111 can be moved down, and the pushing block 112 can be used to push out the toggle column 83, so that the latching tooth is delayed and meshes with the driven gear 75. Then, the rotating rod 41 is rotated to rotate the driven gear 75 and the rotating ring 73. The principle is the same as the above-mentioned over-speed enzyme component. The second limit plate 66 is lifted up by the protrusion 74, so that the street light crossbar 2 can be rotated to the initial position.

[0051] The top of the first support plate 61 is fixedly connected to a support tube 114, the inner wall of the support tube 114 is slidably connected to a top plate 115, the top surface of the top plate 115 is fixedly connected to the bottom surface of the support rod 71, and an elastic member 116 is fixedly connected between the top of the first support plate 61 and the top plate 115, and the elastic member 116 is a compression spring.

[0052] A plurality of strong elastic ropes are fixedly connected between the outer end of the limiting cylinder 52 and the inner wall of the street lamp post body 1 , and are made of strong elastic material. The top of the street lamp post body 1 is rotatably connected to the rotating cylinder 51 via a convex ring plate.

[0053] By utilizing the elastic force of the strong elastic rope, the street light crossbar 2 can be automatically rotated to the initial position at the moment the first limit plate 63 is unlocked. The use of the convex plate can make the rotating drum 51 and the street light post body 1 more tightly combined, and the rotating drum 51 will not separate from the street light post body 1 due to excessive rotation speed.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
