The Bernoulli principle-based cooling and dust removal LED street lamp according to claim 1, wherein the upper end of the threaded rod (6) extends to the upper end of the lamp holder (1) and is fixedly connected with a vent plate (16), the vent plate (16) is rotatably connected with the upper side wall of the lamp holder (1) and covers the upper ends of the vent holes (14), and two arc-shaped communication ports (17) which are arranged in a central symmetry manner about the central axis of the vent plate (16) are arranged on the vent plate (16).
3. The Bernoulli-principle-based cooling and dust-removing LED street lamp and the system thereof according to claim 1, wherein when the LED lamp tube (3) is lighted during use, each electronic element inside the lamp body can continuously emit heat to gradually raise the temperature inside the lamp body, when the temperature inside the lamp body rises to the abnormal temperature of the memory spring (8), the memory spring (8) can extend, the extended memory spring (8) can push the driving plate (7) at the lower end of the memory spring to move downwards, because the inner side wall of the through hole arranged on the driving plate (7) is meshed and connected with the threaded rod (6), the downward moving driving plate (7) can drive the threaded rod (6) to rotate, and the rotating threaded rod (6) can drive the cooling fan (5) to rotate through the single-row bearing, so that the hot air inside the lamp body is discharged, and the temperature inside the lamp body is reduced;
when the driving plate (7) is pushed by the memory spring (8) to move downwards, the lifting rod (9) at the upper end of the driving plate (7) moves downwards along with the memory spring, and because the middle part of the bottom surface of the lamp holder (1) is arranged in an upward arched manner, the dust removal scraper (12) fixedly connected with the lifting rod (9) through the connecting rope (11) can cling to the upper side wall of the lamp body to slide downwards under the action of gravity, so that the dust removal effect is achieved;
when the LED lamp tube (3) is extinguished, the temperature in the lamp body gradually drops below the metamorphosis temperature of the memory spring (8), the memory spring (8) can be contracted and reset, the driving plate (7) at the lower end can be driven to move upwards, the threaded rod (6) meshed and connected with the through hole in the driving plate (7) can rotate reversely, and the threaded rod (6) rotating reversely can not drive the cooling fan (5) to rotate reversely because the lower end of the threaded rod (6) is connected with the cooling fan (5) through the one-way bearing which can not rotate reversely;
when the driving plate (7) moves upwards along with the reset of the memory spring (8), the lifting rod (9) fixedly connected to the upper end of the driving plate (7) is driven to move upwards, so that the dust removal scraper (12) moves upwards under the pulling of the connecting rope (11) to reset;
when wind blows to the wing plates (10), because the lower edges of the wing plates (10) are arc lines arched downwards, the flow velocity of the lower ends of the wing plates (10) is larger than that of the upper ends of the wing plates (10), the Bernoulli principle shows that the pressure of the lower ends of the wing plates (10) is smaller, and the pressure difference of the upper ends and the lower ends of the wing plates (10) can form downward thrust, so that the wing plates (10) move downwards, the lifting rods (9) at the lower ends of the wing plates (10) move downwards along with the pressure difference, one ends of the connecting ropes (11) and the lifting rods (9) fixedly connected can move downwards, and the dust removal scraper (12) at the other ends of the connecting ropes (11) can slide downwards along the upper side wall of the lamp body under the action of gravity to remove dust;
when the wing plate (10) drives the lifting rod (9) to move downwards, the driving plate (7) moving downwards along with the lifting rod (9) drives the threaded rod (6) to rotate under the action of the threads in the through hole, so that the cooling fan (5) at the lower end of the threaded rod (6) rotates to cool the internal elements of the lamp body;
when pterygoid lamina (10) move up under the effect of wind, can make drive plate (7) extrusion memory spring (8) through lifter (9), when the pressure differential of pterygoid lamina (10) upper and lower extreme reduced to be less than memory spring (8) along with the reduction of wind-force when resumeing elasticity, memory spring (8) can push down drive plate (7), make lifter (9) the downward movement of drive plate 7 upper end to drive dust removal scraper blade (12) and shift up and reset.
