Although street lights in cities are usually not directly exposed to strong vibrations caused by extreme natural disasters such as earthquakes, the urban environment is complex and changeable, and street lights need to withstand small vibrations and impacts from different directions, such as heavy traffic, construction activities or strong winds. Long-term vibrations will cause impacts on the internal structure of street lights, affecting the stability of the internal structure of street lights, causing the internal structure of street lights to become loose, deformed or even damaged, thereby affecting the normal lighting function and service life of the street lights. Summary of the invention

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] Embodiment: A heat-dissipating and earthquake-resistant street lamp, such as Figure 1-Figure 8As shown, it includes a shell 1 fixedly connected to a lamp pole fixedly installed on the ground, and the shell 1 is fixedly connected to the lamp pole by bolts or other fixing methods, and the shell 1 can play a dust-proof role; it is worth noting that the lamp pole is a prior art and is not shown in the figure; the inner wall of the shell 1 is equidistantly provided with a plurality of groups of recesses 101, and the recesses 101 can play a guiding and limiting role; the inner wall of the recess 101 is equidistantly provided with a plurality of groups of heat dissipation holes 102, and the heat dissipation holes 102 are obliquely provided on the inner wall of the recess 101, and the heat dissipation holes 102 are obliquely provided, so that the heat generated in the shell 1 can be dissipated, so that the interior of the shell 1 can be lowered; it is worth noting that a filter net can be clamped inside the heat dissipation hole 102 to achieve the purpose of dust prevention, so as to prevent external dust from entering the interior of the shell 1 through the interior of the heat dissipation hole 102; Among them, a lampshade 2 is fixedly installed on the lower end of the shell 1 by bolts. By setting the lampshade 2, it is possible to effectively prevent the invasion of pollutants such as dust, keep the inside of the street lamp clean, extend the service life of the street lamp, and prevent damage to the street lamp caused by accidental touch or collision, thereby playing a protective role; a light source 3 is provided between the shell 1 and the lampshade 2. By setting the light source 3, it can emit light when power is turned on, thereby achieving the purpose of lighting.

[0020] Combined with Figure 1 -Attached Figure 8 , by providing a buffer component 4 for buffering the force generated when the housing 1 is vibrated, when the street lamp is vibrated by the outside, the force generated can be buffered and offset, thereby protecting the internal components of the street lamp; the buffer component 4 includes a disc 401, the disc 401 is arranged between the housing 1 and the lampshade 2, a controller is integrated inside the disc 401, the lower end of the disc 401 is fixedly connected to the light source 3, and the light source 3 is electrically connected to the controller, and by providing the disc 401, the light source 3 can be limited, so that the light source 3 can maintain a fixed position, and can cooperate with the electrically connected controller to realize the function of on and off power; Among them, a plurality of groups of rubber rods 402 are equidistantly installed on the upper surface of the disc 401. By setting the rubber rods 402, since the rubber rods 402 are made of rubber material and have significant elasticity and resilience, they can absorb and disperse the energy generated when the street lamp is vibrated, thereby achieving the purpose of protecting the components between the shell 1 and the lampshade 2; a ball 403 is fixedly installed on the upper end of the rubber rod 402, and the upper end of the ball 403 is movably connected to the inner wall of the shell 1. By setting the ball 403, the disc 401 and the rubber rod 402 can be movably connected to the shell 1, so that when the street lamp is vibrated, the energy generated by the vibration will be absorbed and dispersed by the rubber rod 402 before it acts on the disc 401, and the disc 401 will drive the rubber rod 402 to move slightly, so that the excess energy can be offset, thereby achieving the purpose of protecting the components and avoiding the shaking of the components due to rigid connection, thereby affecting the service life.

[0021] The outer surface of the disk 401 is sleeved with an outer ring 404, and the inner wall of the outer ring 404 is elastically connected to the outer surface of the disk 401 through multiple groups of equidistantly distributed shock-absorbing springs 405. By providing the outer ring 404 and the shock-absorbing springs 405, a positioning function can be achieved, so that the disk 401 can only move slightly when it is vibrated. It is worth noting that by providing the shock-absorbing springs 405, when the disk 401 is vibrated and displaced, the shock-absorbing springs 405 can be squeezed to deform and generate a reaction force, so that the force acting on the disk 401 can be offset, ensuring that the disk 401 can be in a stable state in a vibrating environment, and ensuring the normal lighting and service life of the street lamp. Among them, the surface of the outer ring 404 is provided with multiple groups of grooves 4041 at equal intervals, and the interior of the outer ring 404 is provided with an annular cavity 4042, and the annular cavity 4042 is communicated with the groove 4041. By providing the groove 4041 and the annular cavity 4042, it can play a guiding and limiting role; a temperature vibration sensor is fixedly installed at the lower end of the outer ring 404, and the temperature vibration sensor is electrically connected to the controller integrated inside the disc 401. By setting the temperature vibration sensor, the vibration frequency of the street lamp and the internal temperature thereof can be monitored, so that the staff can formulate a repair and maintenance plan for the street lamp according to the vibration frequency. At the same time, when the temperature between the outer shell 1 and the lampshade 2 rises, the heat dissipation in the outer shell 1 can be controlled to achieve the purpose of cooling.

[0022] Combined with Figure 1 -Attached Figure 8, and also includes a heat dissipation component 5 for dissipating heat between the shell 1 and the inside of the lampshade 2, so that after the temperature inside the shell 1 and the lampshade 2 rises, the heat inside the shell 1 and the lampshade 2 can be dissipated to achieve the purpose of cooling, the purpose of protecting the street lamp parts, slowing down the aging speed of the parts, and extending the lighting time; the heat dissipation component 5 includes a plurality of groups of equally spaced moving rods 501, and by setting the moving rods 501, it can play a connecting role; the upper end of the moving rod 501 is fixedly installed with a bonding plate 502, the bonding plate 502 is arranged inside the recess 101 and slidably cooperates with the inner wall of the recess 101, and by setting the bonding plate 502, it can slide inside the recess 101, and the heat dissipation hole 102 is sealed to prevent dust from entering the shell 1 and the interior of the lampshade 2; The surface of the bonding plate 502 is equidistantly penetrated with a plurality of through holes 503 corresponding to the heat dissipation holes 102, and the through holes 503 are initially offset from the heat dissipation holes 102. By setting the through holes 503, the heat dissipation holes 102 can be coordinated with each other to dissipate heat inside the housing 1 and the lampshade 2, thereby achieving the purpose of cooling. The lower end of the moving rod 501 passes through the groove 4041 and is fixedly connected with a rotating ring 504. By setting the rotating ring 504, the moving rod 501 can be driven to rotate synchronously through its rotation, so that the bonding plate 502 follows the moving rod 501 synchronously. The through hole 503 and the heat dissipation hole 102 are moved to align them, so as to achieve heat dissipation; the rotating ring 504 is arranged inside the annular cavity 4042, and the inner wall of the rotating ring 504 is elastically connected to the inner wall of the annular cavity 4042 through a connecting spring. By setting a connecting spring (existing technology, not shown in the figure), the reaction force generated by its deformation can drive the moving rod 501 and the bonding plate 502 to move, so that the through hole 503 and the heat dissipation hole 102 can be aligned; it is worth noting that when the bonding plate 502 and the heat dissipation hole 102 are not aligned, the connecting spring is in a deformed state; The lower surface of the rotating ring 504 is provided with a plurality of driving grooves 505 at equal intervals, and the inner wall of the driving groove 505 is slidably matched with a telescopic rod 506. By setting the driving groove 505 and the telescopic rod 506, the purpose of driving the rotating ring 504 to rotate can be achieved through the cooperation between the two. It is worth noting that the inner wall of the driving groove 505 is provided with an inclined surface, and the surface of the telescopic rod 506 is correspondingly provided with a matching surface, so that when the telescopic rod 506 enters the interior of the driving groove 505, it can better drive the rotating ring 50 4 rotation; the telescopic rod 506 is fixedly mounted on the bottom surface of the annular cavity 4042, and the telescopic rod 506 is electrically connected to the controller integrated in the disc 401. When the housing 1 and the lampshade 2 need to dissipate heat, the telescopic rod 506 can be powered off, so that the telescopic rod 506 can be moved out of the driving groove 505, so that the rotating ring 504 can drive the bonding plate 502 to move through the moving rod 501, so that the through hole 503 is aligned with the heat dissipation hole 102 for heat dissipation.

[0023] Specifically, when the street lamp is subjected to external vibration during use, it will be recorded in time by the temperature vibration sensor, and the energy generated by the vibration will first be transferred to the rubber rod 402. After being absorbed and dispersed by the rubber rod 402, the remaining energy will act on the disc 401. Since the disc 401 and the rubber rod 402 are movably connected to the inner wall of the shell 1 through the ball 403, the disc 401 will deviate; when the disc 401 deviates, it will squeeze the shock-absorbing spring 405 fixedly connected to its surface, causing the shock-absorbing spring 405 to deform and generate a reaction force, thereby offsetting the energy acting on the disc 401, ensuring the stability of the disc 401 and the light source 3, and achieving the purpose of normal lighting; When the internal temperature of the housing 1 and the lampshade 2 rises and needs to be cooled, the temperature vibration sensor will send an electrical signal to the controller, which will cut off the power to the telescopic rod 506, so that the telescopic rod 506 is restored to its original position, and then moves out from the inside of the driving groove 505, releasing the restriction on the rotating ring 504. When the rotating ring 504 is released from the restriction, the connecting spring in the deformed state will drive the rotating ring 504 to start rotating, and then drive the moving rod 501 to slide inside the groove 4041. The moving moving rod 501 will drive the fitting plate 502 to slide inside the notch 101, so that the through hole 503 Aligned with the heat dissipation hole 102, the heat dissipation of the inside of the shell 1 and the lampshade 2 begins, thereby extending the service life of the street lamp; when the heat dissipation is completed, the temperature vibration sensor sends an electrical signal to the controller, and starts to energize the telescopic rod 506, so that the telescopic rod 506 begins to extend, and the matching surface opened on its surface is squeezed with the inclined surface opened on the inner wall of the driving groove 505, so that the rotating ring 504 begins to rotate in the opposite direction and drives the connecting spring to deform, thereby driving the moving rod 501 and the bonding plate 502 to return to their original position, and the heat dissipation hole 102 is sealed to prevent external dust from entering the inside of the shell 1 and the lampshade 2.
