Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of street lamps, and in particular to a protection device for LED street lamps. Background Art
[0002] LED street lights refer to road lighting fixtures that use light-emitting diodes as light sources. Compared with traditional street lights, LED street lights have higher energy efficiency, longer service life, and better color reproduction. Its working principle is to directly convert electrical energy into light energy, reducing the energy waste caused by heat loss in traditional lamps.
[0003] After searching, the Chinese patent with publication number CN118517660B discloses a protection device for LED street lamps. In the strong wind period, the street lamp crossbar is allowed to swing slowly with the wind 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 to block the wind, thereby achieving the purpose of protecting the street lamp crossbar and the street lamp head; in addition, in order to prevent the street lamp head from deflecting the irradiation area when the street lamp crossbar turns, by driving the steering component, the driving control rod can be adaptively rotated when the street lamp crossbar rotates, thereby achieving the irradiation area of the street lamp head remains unchanged. However, when this solution is actually used, there are still the following shortcomings: In the existing road lighting system, street lamps are usually installed on both sides of the road to ensure the safety of vehicles and pedestrians at night. However, in actual applications, it is found that vehicles may accidentally hit street lamp poles, especially at turns, due to insufficient driver reaction time or driving errors. This collision may not only cause damage to the street lamp itself, but also because the street lamp is supported only by the lamp post body, its structural stability is particularly fragile when it is impacted by external forces. Once a collision occurs, the lamp post may not be able to withstand the impact force and may tilt or even collapse, which will not only interrupt the normal lighting of the area and affect the safety of road traffic, but may also pose a potential threat to surrounding facilities, other vehicles and pedestrians, increasing the risk of traffic accidents and maintenance costs.

[0016] Beneficial effects of the present invention: 1.

[0025] like Figures 1 to 10 As shown, a protective device for an LED street lamp comprises a lamp pole 1 and a support rod 2 hinged at the top of the lamp pole 1, a lamp board 3 is fixedly mounted at the end of the support rod 2, a avoidance component is arranged at the bottom end of the lamp pole 1, a buffer component corresponding to the avoidance component is arranged at the bottom end of the lamp pole 1, and a storage component is arranged between the lamp pole 1 and the support rod 2; The avoidance component includes a base 41 arranged at the bottom end of the lamp pole 1, a buffer groove 42 is provided on the top surface of the base 41, a receiving groove 43 connected to the buffer groove 42 is provided inside the base 41, a base plate 44 is movably installed on the inner wall of the receiving groove 43, and the bottom end of the lamp pole 1 is fixedly connected to the top surface of the base plate 44, the diameter of the base plate 44 is at least smaller than the inner diameter of the receiving groove 43, a buffer airbag ring 45 corresponding to the lamp pole 1 is fixedly installed on the inner wall of the buffer groove 42, the interior of the buffer airbag ring 45 is filled with buffer oil, a cover plate 46 corresponding to the buffer groove 42 is provided on the top surface of the base 41, four grooves 47 distributed in an annular array are provided on the top surface of the base 41, a plug rod 48 is slidably installed on the inner wall of the groove 47, a spring 49 is fixedly installed between the bottom surface of the plug rod 48 and the inner bottom surface of the groove 47, and four sockets 410 distributed in an annular array and corresponding to the plug rod 48 are provided on the top surface of the cover plate 46; When in use, under normal conditions, the support rod 2 is in a fixed state relative to the lamp pole 1, and the lamp panel 3 can be used for normal lighting. The base 41 is located in the concrete foundation of the street lamp and is integrated with the concrete foundation for use. In the initial state, the plug rod 48 is located in the socket 410 on the cover plate 46 under the support of the spring 1 49, and the cover plate 46 is limited so that the cover plate 46 covers the buffer groove 42. Under the action of the buffer component, the plug rod 48 in the socket 410 can be squeezed, so that the plug rod 48 slides downward along the slot 47. , the insertion rod 48 in the socket 410 can be completely squeezed into the groove 47, and the limit on the cover plate 46 and the lamp pole 1 can be released. After the limit on the cover plate 46 and the lamp pole 1 is released, as the vehicle hits, the base plate 44 at the bottom end of the lamp pole 1 can move in the receiving groove 43, producing an evasive effect, leaving the driver with reaction time. At the same time, when the lamp pole 1 and the base plate 44 move to avoid, the lamp pole 1 can squeeze the buffer airbag ring 45 in the buffer groove 42, and the buffer airbag ring 45 is filled with buffer oil, so the lamp pole 1 can be further buffered.
[0026] like Figure 4 , Figure 5 , Figure 6 As shown, the buffer assembly includes two collars 51 slidably mounted on the outer wall of the lamp pole 1, the outer walls of the two collars 51 are fixedly mounted with a plurality of reinforcing ribs 52 distributed in a circular array, a plurality of elastic ribs 53 are fixedly mounted on the plurality of reinforcing ribs 52, the outer wall of the lamp pole 1 is provided with two guide openings 54 corresponding to the collars 51, the inner walls of the two collars 51 are fixedly mounted with guide blocks 55, and the guide blocks 55 are slidably connected with the guide openings 54, the outer wall of the collar 51 located at the lower part of the two collars 51 is fixedly mounted with four support plates 56 distributed in a circular array, the bottom surfaces of the ends of the four support plates 56 are fixedly mounted with top rods 57 adapted to the insertion rod 48, and the length of the top rod 57 is the same as the depth of the socket 410; When the LED street lamps on both sides of the road are hit by a vehicle, the reinforcing ribs 52 and the elastic ribs 53 are located at the outer side of the bottom end of the lamp pole 1. When the vehicle hits, the reinforcing ribs 52 and the elastic ribs 53 are first contacted. When the reinforcing ribs 52 and the elastic ribs 53 are used together, the reinforcing ribs 52 are normally protruding outward. Therefore, when the vehicle contacts the protruding part of the reinforcing ribs 52, the protruding part can be hit, so that the reinforcing ribs 52 are bent and deformed. In the process of deformation, the elastic ribs 53 have a certain elastic force, and as the reinforcing ribs 52 are deformed, the reinforcing ribs 52 are deformed. The variable elastic ribs 53 can support the reinforcing ribs 52 so as to provide preliminary buffering for the vehicle. At the same time, when the reinforcing ribs 52 are deformed, they can push the two rings 51 at both ends, so that the guide blocks 55 on the inner walls of the rings 51 slide along the guide openings 54. When the lower ring 51 slides, it can drive the four support plates 56 and the top rod 57 to slide. Before the lamp pole 1 collapses, the coordinated use of the reinforcing ribs 52 and the elastic ribs 53 can provide greater tensile force to the lamp pole 1. Compared with normal street lamps, the LED street lamps proposed in this scheme have a lower probability of collapse and better protective performance.
[0027] like Figure 7 , Figure 8 , Fig.10 As shown, the storage assembly includes a pin rod 61 that is arranged through the outer wall of the lamp pole 1, the outer wall of the pin rod 61 located on the outer side of the lamp pole 1 is sleeved with a spring 2 62, and the two ends of the spring 2 62 are respectively fixedly connected to the pin rod 61 and the lamp pole 1, a pin groove 63 corresponding to the pin rod 61 is provided at one end of the support rod 2 away from the lamp board 3, a U-shaped frame 64 is arranged through the outer wall of the lamp pole 1 at a position below the support rod 2, a hoop plate 65 is fixedly installed at one end of the U-shaped frame 64 located on the outer side of the lamp pole 1, a plurality of convex hulls are provided on the inner wall of the hoop plate 65, and the inner diameter of the hoop plate 65 is adapted to the outer diameter of the support rod 2, two springs 3 66 are sleeved on the outer wall of the U-shaped frame 64, and the two ends of the spring 3 66 are respectively fixedly connected to the U-shaped frame 64 and the lamp pole 1, a transmission plate 67 is slidably installed on the inner wall of the lamp pole 1, and the bottom end of the transmission plate 67 is fixedly connected to the side of an upper guide block 55, and a yield opening 68 corresponding to the pin rod 61 is provided on the side of the transmission plate 67; When the reinforcing rib 52 deforms and drives the two collars 51 to slide, the upper collar 51 can drive the transmission plate 67 to slide upward through the guide block 55. In the initial state, the pin rod 61 abuts against the transmission plate 67, so it can be inserted into the pin groove 63 at the end of the support rod 2, ensuring the stability of the pin groove 63 during normal use. As the transmission plate 67 slides, the clearance opening 68 on the transmission plate 67 can be opposite to the pin rod 61. At this time, under the action of the second spring 62, the pin rod 61 can slide toward the inside of the lamp pole 1. The pin rod 61 moves out of the pin groove 63, releasing the limit on the support rod 2. With the inertia of the lamp pole 1 when it is hit and the gravity of the support rod 2 and the lamp board 3, the support rod 2 can drive the lamp board 3 to rotate toward the ground after the limit is released; and when the support rod 2 rotates, it can be engaged into the hoop plate 65. Under the engaging action of the hoop plate 65, the support rod 2 can be fixed, so that the support rod 2 is stored from the original horizontal state to the vertical state, ensuring that the covered area is smaller when the lamp pole 1 collapses due to a hit, thereby increasing safety.
[0028] like Fig. 9 , Fig.10 As shown, an emergency component is provided at the top of the lamp pole 1, and the emergency component includes a fixed shell 71 fixedly installed on the top of the lamp pole 1, a lifting plate 72 is slidably installed on the inner wall of the fixed shell 71, and the outer wall of the lifting plate 72 is fitted with the inner wall of the fixed shell 71, and a top cover 73 is fixedly installed on the top of the lifting plate 72, and the top cover 73 is adapted to the open end of the fixed shell 71, and an expansion airbag ring 74 is fixedly installed on the inner wall of the lifting plate 72, and a pull rod 75 is fixedly installed on the bottom surface of the lifting plate 72, and the bottom end of the pull rod 75 passes through the bottom surface of the fixed shell 71 and is located at the position of the U-shaped frame 64, and a spring four 76 is sleeved on the pull rod 75, and the two ends of the spring four 76 are fixedly connected to the fixed shell 71 and the pull rod 75, respectively, and a limiting rod 77 is fixedly installed on the outer wall of the U-shaped frame 64, and a limiting groove 78 corresponding to the limiting rod 77 is opened at the bottom end of the pull rod 75, and the expansion airbag ring 74 and the buffer airbag ring 45 are connected through a conduit 79; When the support rod 2 enters the hoop plate 65, it can hit the hoop plate 65, so that the U-shaped frame 64 can also slide in the direction of entering the interior of the lamp pole 1. As the U-shaped frame 64 slides, the limiting rod 77 on the U-shaped frame 64 moves out of the limiting groove 78 at the bottom end of the pull rod 75, thereby releasing the limit on the pull rod 75. At this time, under the support of the spring 4 76, the pull rod 75, the lifting plate 72 and the top cover 73 can slide upward, so that the lifting plate 72 moves out of the fixed shell 71. When the lifting plate 72 is located in the fixed shell 71, the airbag ring 74 is inflated. When the buffer airbag ring 45 is in the stored state and under the limiting action of the fixed shell 71, the buffer oil in it cannot enter into the expansion airbag ring 74 when it is squeezed. As the lifting plate 72 moves out of the fixed shell 71, the expansion airbag ring 74 is released from the limit, and the buffer oil in the buffer airbag ring 45 can enter into the expansion airbag ring 74 through the conduit 79, so that the expansion airbag ring 74 expands and opens, so as to provide support for the lamp pole 1 when the lamp pole 1 collapses, so that the lamp pole 1 will not directly contact the ground, leaving a certain space to avoid crushing surrounding people.
[0029] The technical solution provided by the present invention is that when in use, under normal conditions, the support rod 2 is in a fixed state relative to the lamp pole 1, the lamp panel 3 can be used for normal lighting, the base 41 is located in the concrete foundation of the street lamp, and is used in an integrated manner with the concrete foundation. If the LED street lamps on both sides of the road are hit by a vehicle, first, the reinforcing ribs 52 and the elastic ribs 53 are located at the outer position of the bottom end of the lamp pole 1. When the vehicle hits, the reinforcing ribs 52 and the elastic ribs 53 can first be in contact with the reinforcing ribs 52 and the elastic ribs 53. When the reinforcing ribs 52 and the elastic ribs 53 are used in coordination, the normal state of the reinforcing ribs 52 is a shape that protrudes outward. Therefore, when the vehicle contacts the protrusion on the reinforcing rib 52, the protrusion can be hit, thereby causing the reinforcing rib 52 to bend and deform. In the process of deformation, the elastic ribs 53 have a certain elastic force, and as the reinforcing ribs 52 are deformed, the elastic ribs 53 can support the reinforcing ribs 52 The support is used to provide a preliminary buffer for the vehicle. At the same time, when the reinforcing rib 52 is deformed, the two collars 51 at both ends can be pushed, so that the guide block 55 on the inner wall of the collar 51 slides along the guide opening 54. When the collar 51 at the bottom slides, it can drive the four support plates 56 and the top rod 57 to slide. In the initial state, under the support of the spring 1 49, the plug rod 48 is located in the socket 410 on the cover plate 46, and the cover plate 46 is limited so that the cover plate 46 covers the buffer groove 42. When the top rod 57 slides with the collar 51, it can be inserted into the socket 410 and squeeze the plug rod 48 in the socket 410, so that the plug rod 48 slides downward along the slot 47. At the same time, the top rod 57 has the same depth as the socket 410, so the plug rod 48 in the socket 410 can be completely squeezed into the slot 47, thereby releasing the limit on the cover plate 46 and the lamp pole 1. After the cover plate 46 and the lamp pole 1 are released from the limit, as the vehicle hits, the reinforcing ribs 52 and the elastic ribs 53 can push the lamp pole 1, so that the base plate 44 at the bottom of the lamp pole 1 can move in the receiving groove 43, producing an evasive effect, leaving the driver with reaction time. At the same time, when the lamp pole 1 and the base plate 44 move to evade, the lamp pole 1 can squeeze the buffer airbag ring 45 in the buffer groove 42, and the buffer airbag ring 45 is filled with buffer oil, so the lamp pole 1 can be further buffered; when the reinforcing rib 52 deforms and drives the two rings 51 to slide, the upper ring 51 can slide through the guide block 55 to drive the transmission The plate 67 slides upwards. In the initial state, the pin rod 61 abuts against the transmission plate 67, so that it can be inserted into the pin groove 63 at the end of the support rod 2, ensuring the stability of the pin groove 63 during normal use. As the transmission plate 67 slides, the clearance opening 68 on the transmission plate 67 can be opposite to the pin rod 61. At this time, under the action of the second spring 62, the pin rod 61 can slide toward the inside of the lamp pole 1, so that the pin rod 61 moves out of the pin groove 63, and the limit on the support rod 2 is released. With the inertia of the lamp pole 1 when it is hit and the gravity of the support rod 2 and the lamp board 3, the support rod 2 can drive the lamp board 3 to rotate toward the ground after the limit is released; When the support rod 2 rotates, it can be engaged into the hoop plate 65. Under the engaging effect of the hoop plate 65, the support rod 2 can be fixed, so that the support rod 2 is stored from the original horizontal state to the vertical state, ensuring that the covered area is smaller when the lamp pole 1 collapses due to impact, thereby increasing safety; and when the support rod 2 enters the hoop plate 65, it can impact the hoop plate 65, so that the U-shaped frame 64 can also slide in the direction of entering the interior of the lamp pole 1. As the U-shaped frame 64 slides, the limiting rod 77 on the U-shaped frame 64 moves out of the limiting groove 78 at the bottom end of the pull rod 75, thereby releasing the limit on the pull rod 75. At this time, under the support of the spring four 76, the pull rod 75, the lifting plate 72 and the top cover 73 can slide upward, so that the lifting plate 72 moves out of the fixed shell 71, and the lifting plate 72 is located in the fixed shell 71. When the expansion airbag ring 74 is in a retracted state, and under the limiting action of the fixed shell 71, the buffer oil in the buffer airbag ring 45 cannot enter the expansion airbag ring 74 when it is squeezed, and as the lifting plate 72 moves out of the fixed shell 71, the expansion airbag ring 74 is released from the limit, and the buffer oil in the buffer airbag ring 45 can enter the expansion airbag ring 74 through the conduit 79, so that the expansion airbag ring 74 expands and opens, so as to provide support for the lamp pole 1 when the lamp pole 1 collapses, so that the lamp pole 1 will not directly contact the ground, leaving a certain space to avoid crushing surrounding personnel, and at the same time, before the lamp pole 1 collapses, the coordinated use of the reinforcing ribs 52 and the elastic ribs 53 can provide greater tensile force to the lamp pole 1. Compared with normal street lamps, the LED street lamps proposed in this scheme have a smaller probability of collapse and better protection performance.
