The design purpose of the dust removing strip mechanism is that when the square water container is filled with rainwater, the whole floating block is positioned in the rainwater, and the buoyancy force borne by the floating block is the largest; at the moment, the floating block enables the guide block to overcome the limit of the limiting block and slide upwards along the trigger groove at a high instantaneous acceleration under the action of buoyancy, and the reset plate spring is stretched; the guide block drives the first rack to move upwards; the first rack drives the second gear to rotate through the first gear, the first one-way clutch, the first transmission shaft, the first bevel gear, the second bevel gear and the second transmission shaft; the second one-way clutch does not form a barrier to the first transmission shaft at this time; the cylindrical water container is filled with rainwater; the third gear slides downwards along the first pin under the action of the gravity of rainwater in the cylindrical water container and is meshed with the second gear and the second rack; the first return spring is compressed; the second gear drives the third gear to rotate; the third gear drives the supporting plate and the first return spring to rotate together through three first pins; the third gear drives the dust removing strip to slide along the bottom surface of the lampshade through a second rack, a connecting rod, a pressure rod, a telescopic outer sleeve and a telescopic inner rod; the second return spring is stretched, and the dust removal work of the dust removal strip is started; meanwhile, the first rack drives the baffle to move upwards through the L-shaped connecting rod; the fourth drain hole is opened; rainwater in the square water container and the trigger cavity is quickly discharged; the buoyancy force borne by the floating block disappears, and under the action of the reset plate spring, the first rack drives the guide block, the floating block, the L-shaped connecting rod and the baffle plate to move downwards together to return to the initial position; the baffle plate blocks the fourth drain hole again; the rotation of the first rack drives the first gear to rotate, and the first gear cannot drive the first transmission shaft to rotate reversely through the first one-way clutch; the first transmission shaft cannot rotate reversely under the action of the second one-way clutch; the first bevel gear, the second transmission shaft, the second gear and the third gear cannot rotate reversely; the second rack can not reversely slide back to the initial position under the action of the second return spring when staying at the original position; when the square water container is quickly filled with rainwater again, the whole floating block is positioned in the rainwater, and the buoyancy force borne by the floating block is maximum; at the moment, the floating block enables the guide block to overcome the limit of the limiting block and slide upwards along the trigger groove at a high instantaneous acceleration under the action of buoyancy, and the reset plate spring is stretched; the guide block drives the first rack to move upwards; the first rack drives the second gear to rotate through the first gear, the first one-way clutch, the first transmission shaft, the first bevel gear, the second bevel gear and the second transmission shaft; the second one-way clutch does not form a barrier to the first transmission shaft at this time; the second gear drives the third gear to rotate; the third gear drives the supporting plate and the first return spring to rotate together through three first pins; the third gear drives the dust removing strip to continuously slide along the bottom surface of the lampshade on the basis of the first sliding through the second rack, the connecting rod, the pressure rod, the telescopic outer sleeve and the telescopic inner rod; the second return spring is further stretched; meanwhile, the first rack drives the baffle to move upwards through the L-shaped connecting rod; the fourth drain hole is opened; rainwater in the square water container and the trigger cavity is quickly discharged; the buoyancy force borne by the floating block disappears, and under the action of the reset plate spring, the first rack drives the guide block, the floating block, the L-shaped connecting rod and the baffle plate to move downwards together to return to the initial position; the baffle plate blocks the fourth drain hole again; the rotation of the first rack drives the first gear to rotate, and the first gear cannot drive the first transmission shaft to rotate reversely through the first one-way clutch; the first transmission shaft cannot rotate reversely under the action of the second one-way clutch; the first bevel gear, the second transmission shaft, the second gear and the third gear cannot rotate reversely; the second rack can not reversely slide back to the initial position under the action of the second return spring when staying at the original position; the rainwater in the square water container and the trigger cavity is filled and emptied repeatedly; the dust removing strips continuously slide along the same direction; until the dust removing strip moves to the other end of the lampshade, the second rack is separated from the third gear and is not meshed with the third gear, and the third gear enables the second rack to be kept still in place under the pulling of a second return spring; when the rain stops, the rain water in the cylindrical water container, the square water container and the trigger groove is emptied; the rainwater gravity acting on the upper end surface of the third gear disappears; under the action of the restoring force of the first return spring, the third gear moves upwards to return to the initial position, and meanwhile, the third gear is separated from the second rack and the second gear; under the action of the restoring force of the second return spring, the connecting rod drives the second rack to return to the initial position; the connecting rod drives the dedusting strip to reversely slide along the bottom surface of the inner wall of the lampshade through the pressure rod, the telescopic outer sleeve and the telescopic inner rod and return to the initial position;

in the whole rain falling process, the dust removing strip continuously slides along the same direction all the time; when the rain stops, the dust removing strip slides to the initial position under the action of the second return spring; the dust removing strip realizes that the next rain slides in the lampshade to and fro.

The third drain hole and the fifth drain hole have the function that when the rain stops, the rain water in the square water container is drained out slowly and completely through the third drain hole; rainwater in the cylindrical water container is slowly drained out through the fifth drain hole, so that the third gear is separated from the second gear and the second rack under the action of the first return spring and returns to the initial position.

The diameters of the third drain hole and the fifth drain hole are very small, and the drainage speed of the third drain hole and the fifth drain hole is far less than the speed of injecting rainwater into the container; as long as the rain does not stop, the drainage of the third drain hole and the fifth drain hole does not play any role; when the rain stops, the third drain hole on the square water container slowly drains the water in the square water container and empties the square water container; a fifth drain hole on the cylindrical water container slowly drains the water in the cylindrical water container and empties the cylindrical water container; the internal structure of the street lamp mechanism is completely reset to the initial position.

The design purpose that the appearance size of the fourth drain hole is larger than that of the third drain hole, and the lower end face of the fourth drain hole is flush with the lower end face of the floating block at the initial position and is equal to the height of the floating block is that the appearance size of the fourth drain hole is larger than that of the third drain hole so as to increase the drainage speed of the fourth drain hole; when the square water container is filled with rainwater and the whole floating block is positioned in the rainwater, the floating block is subjected to the largest buoyancy; at the moment, the floating block enables the guide block to overcome the limit of the limiting block and slide upwards along the trigger groove at a high instantaneous acceleration under the action of buoyancy, and the reset plate spring is stretched; the guide block drives the first rack to move upwards; the first rack drives the second gear to rotate through the first gear, the first one-way clutch, the first transmission shaft, the first bevel gear, the second bevel gear and the second transmission shaft; the second one-way clutch does not form a barrier to the first transmission shaft at this time; the cylindrical water container is filled with rainwater; the third gear slides downwards along the first pin under the action of the gravity of rainwater in the cylindrical water container and is meshed with the second gear and the second rack; the first return spring is compressed; the second gear drives the third gear to rotate; the third gear drives the supporting plate and the first return spring to rotate together through three first pins; the third gear drives the dust removing strip to slide along the bottom surface of the lampshade through a second rack, a connecting rod, a pressure rod, a telescopic outer sleeve and a telescopic inner rod; the second return spring is stretched, and the dust removal work of the dust removal strip is started; meanwhile, the first rack drives the baffle to move upwards through the L-shaped connecting rod; the fourth drain hole is opened; rainwater in the square water container and the trigger cavity is quickly discharged; the buoyancy force borne by the floating block disappears, and under the action of the reset plate spring, the first rack drives the guide block, the floating block, the L-shaped connecting rod and the baffle plate to move downwards together to return to the initial position; the baffle plate blocks the fourth drain hole again; the rotation of the first rack drives the first gear to rotate, and the first gear cannot drive the first transmission shaft to rotate reversely through the first one-way clutch; the first transmission shaft cannot rotate reversely under the action of the second one-way clutch; the first bevel gear, the second transmission shaft, the second gear and the third gear cannot rotate reversely; the second rack can not reversely slide back to the initial position under the action of the second return spring when staying at the original position; the lower end surface of the fourth drain hole is flush with the lower end surface of the floating block at the initial position and is equal in height, so that when the water level of rainwater in the square water container and the trigger cavity is lowered to be flush with the fourth drain hole, the rainwater level does not fall; at the moment, the floating block just falls back to the initial position and just contacts with the water surface, and buoyancy does not exist; when the water is accumulated again in the square water container and the square water container is filled with the water, the time required by the square water container is shorter than the time required by the square water container which is filled with the rainwater for the first time, so that the time interval of the movement of the dust removing strip towards the same direction is shortened.

When raining, the square water container is filled with rainwater, the whole floating block is positioned in the rainwater, and the buoyancy force borne by the floating block is maximum; at the moment, the floating block enables the guide block to overcome the limit of the limiting block and slide upwards along the trigger groove at a high instantaneous acceleration under the action of buoyancy, and the reset plate spring is stretched; the guide block drives the first rack to move upwards; the first rack drives the second gear to rotate through the first gear, the first one-way clutch, the first transmission shaft, the first bevel gear, the second bevel gear and the second transmission shaft; the second one-way clutch does not form a barrier to the first transmission shaft at this time; the cylindrical water container is filled with rainwater; the third gear slides downwards along the first pin under the action of the gravity of rainwater in the cylindrical water container and is meshed with the second gear and the second rack; the first return spring is compressed; the second gear drives the third gear to rotate; the third gear drives the supporting plate and the first return spring to rotate together through three first pins; the third gear drives the dust removing strip to slide along the bottom surface of the lampshade through a second rack, a connecting rod, a pressure rod, a telescopic outer sleeve and a telescopic inner rod; the second return spring is stretched, and the dust removal work of the dust removal strip is started; meanwhile, the first rack drives the baffle to move upwards through the L-shaped connecting rod; the fourth drain hole is opened; rainwater in the square water container and the trigger cavity is quickly discharged; the buoyancy force borne by the floating block disappears, and under the action of the reset plate spring, the first rack drives the guide block, the floating block, the L-shaped connecting rod and the baffle plate to move downwards together to return to the initial position; the baffle plate blocks the fourth drain hole again; the rotation of the first rack drives the first gear to rotate, and the first gear cannot drive the first transmission shaft to rotate reversely through the first one-way clutch; the first transmission shaft cannot rotate reversely under the action of the second one-way clutch; the first bevel gear, the second transmission shaft, the second gear and the third gear cannot rotate reversely; the second rack is not to be slid back to the initial position in place under the action of the second return spring.

When the square water container is quickly filled with rainwater again, the whole floating block is positioned in the rainwater, and the buoyancy force borne by the floating block is maximum; at the moment, the floating block enables the guide block to overcome the limit of the limiting block and slide upwards along the trigger groove at a high instantaneous acceleration under the action of buoyancy, and the reset plate spring is stretched; the guide block drives the first rack to move upwards; the first rack drives the second gear to rotate through the first gear, the first one-way clutch, the first transmission shaft, the first bevel gear, the second bevel gear and the second transmission shaft; the second one-way clutch does not form a barrier to the first transmission shaft at this time; the second gear drives the third gear to rotate; the third gear drives the supporting plate and the first return spring to rotate together through three first pins; the third gear drives the dust removing strip to continuously slide along the bottom surface of the lampshade on the basis of the first sliding through the second rack, the connecting rod, the pressure rod, the telescopic outer sleeve and the telescopic inner rod; the second return spring is further stretched; meanwhile, the first rack drives the baffle to move upwards through the L-shaped connecting rod; the fourth drain hole is opened; rainwater in the square water container and the trigger cavity is quickly discharged; the buoyancy force borne by the floating block disappears, and under the action of the reset plate spring, the first rack drives the guide block, the floating block, the L-shaped connecting rod and the baffle plate to move downwards together to return to the initial position; the baffle plate blocks the fourth drain hole again; the rotation of the first rack drives the first gear to rotate, and the first gear cannot drive the first transmission shaft to rotate reversely through the first one-way clutch; the first transmission shaft cannot rotate reversely under the action of the second one-way clutch; the first bevel gear, the second transmission shaft, the second gear and the third gear cannot rotate reversely; the second rack can not reversely slide back to the initial position under the action of the second return spring when staying at the original position; the rainwater in the square water container and the trigger cavity is filled and emptied repeatedly; the dust removing strips continuously slide along the same direction; and the second rack is separated from the third gear and is not meshed with the third gear until the dust removing strip moves to the other end of the lampshade, and the third gear enables the second rack to be kept still in place under the pulling of the second return spring.

The design purpose of the dust removing strip mechanism 56 in the invention is that when the square water container 21 is filled with rainwater, the whole floating block 34 is positioned in the rainwater, and the buoyancy force applied to the floating block 34 is the largest; at this time, the floating block 34 makes the guide block 35 slide upwards along the trigger groove 29 with a very high instantaneous acceleration against the limit of the limit block 37 under the action of the floating force, and the reset plate spring 73 is stretched; the guide block 35 drives the first rack 36 to move upwards; the first rack 36 drives the second gear 49 to rotate through the first gear 41, the first one-way clutch 42, the first transmission shaft 43, the first bevel gear 44, the second bevel gear 45 and the second transmission shaft 46;

the fourth drain hole 27 is opened; rainwater in the square water container 21 and the trigger cavity 26 is quickly drained; the buoyancy force applied to the floating block 34 disappears, and under the action of the reset plate spring 73, the first rack 36 drives the guide block 35, the floating block 34, the L-shaped connecting rod 39 and the baffle 40 to move downwards together to return to the initial position; the baffle 40 blocks the fourth drain hole 27 again; the rotation of the first rack 36 drives the first gear 41 to rotate, and the first gear 41 does not drive the first transmission shaft 43 to rotate reversely through the first one-way clutch 42; the first transmission shaft 43 does not rotate reversely due to the second one-way clutch 72; the first bevel gear 44, the second bevel gear 45, the second transmission shaft 46, the second gear 49 and the third gear 50 do not rotate reversely; the second rack 57 is to be in place not to slide back to the initial position under the action of the second return spring 64; when the square water container 21 is filled with rainwater quickly again, the whole floating block 34 is positioned in the rainwater, and the buoyancy force applied to the floating block 34 is the maximum; at this time, the floating block 34 makes the guide block 35 slide upwards along the trigger groove 29 with a very high instantaneous acceleration against the limit of the limit block 37 under the action of the floating force, and the reset plate spring 73 is stretched; the guide block 35 drives the first rack 36 to move upwards; the first rack 36 drives the second gear 49 to rotate through the first gear 41, the first one-way clutch 42, the first transmission shaft 43, the first bevel gear 44, the second bevel gear 45 and the second transmission shaft 46; the second one-way clutch 72 does not obstruct the first transmission shaft 43 at this time; the second gear 49 drives the third gear 50 to rotate; the third gear 50 rotates the support plate 54 and the first return spring 52 together through three first pins 53; the third gear 50 drives the dust removing strip 62 to continuously slide along the bottom surface of the lampshade 15 on the basis of the first sliding through the second rack 57, the connecting rod 58, the pressure rod 59, the telescopic outer sleeve 60 and the telescopic inner rod 61; the second return spring 64 is further stretched; meanwhile, the first rack 36 drives the baffle 40 to move upwards through the L-shaped connecting rod 39; the fourth drain hole 27 is opened; rainwater in the square water container 21 and the trigger cavity 26 is quickly drained; the buoyancy force applied to the floating block 34 disappears, and under the action of the reset plate spring 73, the first rack 36 drives the guide block 35, the floating block 34, the L-shaped connecting rod 39 and the baffle 40 to move downwards together to return to the initial position; the baffle 40 blocks the fourth drain hole 27 again; the rotation of the first rack 36 drives the first gear 41 to rotate, and the first gear 41 does not drive the first transmission shaft 43 to rotate reversely through the first one-way clutch 42; the first transmission shaft 43 does not rotate reversely due to the second one-way clutch 72; the first bevel gear 44, the second bevel gear 45, the second transmission shaft 46, the second gear 49 and the third gear 50 do not rotate reversely; the second rack 57 is to be in place not to slide back to the initial position under the action of the second return spring 64; the rainwater in the water square container 21 and the trigger chamber 26 is repeatedly filled and emptied; the dusting strips 62 continue to slide in the same direction; until the dust removing bar 62 moves to the other end of the lampshade 15, the second bar 57 is disengaged from the third gear 50 and is not meshed any more, and the second bar 57 is made to stand still by the third gear 50 under the pulling of the second return spring 64; when the rain stops, the rainwater in the cylindrical water container 31, the square water container 21 and the trigger groove 29 is emptied; the gravity of the rainwater acting on the upper end surface of the third gear 50 disappears; the third gear 50 moves back up to the initial position by the restoring force of the first return spring 52, and at the same time, the third gear 50 is separated from the second rack 57 and the second gear 49; under the restoring force of the second return spring 64, the connecting rod 58 drives the second rack 57 to return to the initial position; the connecting rod 58 drives the dedusting strip 62 to reversely slide along the bottom surface of the inner wall of the lampshade 15 through the pressure rod 59, the telescopic outer sleeve 60 and the telescopic inner rod 61 and returns to the initial position; under the action of the reset plate spring 73, the first rack 36 drives the first gear 41 to rotate and simultaneously drives the baffle 40, the guide block 35 and the floating block 34 to return to the initial position, and the baffle 40 blocks the fourth drain hole 27 again; in the whole rain process, the dust removing strip 62 continuously slides along the same direction all the time; when the rain stops, the dust removal strip 62 slides to the initial position under the action of the second return spring 64; the dusting strips 62 allow the next rain to slide one round trip within the globe 15.

The third drain hole 22 and the fifth drain hole 32 of the present invention are used for draining the rainwater in the water container 21 through the third drain hole 22 slowly and completely after the rain stops; the rainwater in the cylindrical water container 31 is slowly drained through the fifth drain hole 32 to the maximum, so that the third gear 50 is separated from the second gear 49 and the second rack 57 by the first return spring 52 and returns to the initial position.

The diameters of the third drain hole 22 and the fifth drain hole 32 are very small, and the drainage speed of the third drain hole 22 and the fifth drain hole 32 is far less than the speed of injecting rainwater into the container; as long as the rain does not stop, the drainage of the third drain hole 22 and the fifth drain hole 32 does not play any role; when the rain stops, the third drain hole 22 on the square water container 21 slowly drains and empties the water therein; the fifth drain hole 32 on the cylindrical water container 31 slowly drains and empties the water therein; the internal structure of the street lamp mechanism 2 is reset to the initial position.

The design purpose of the invention is that the appearance size of the fourth drain hole 27 is larger than that of the third drain hole 22, and the lower end surface of the fourth drain hole 27 is flush with the lower end surface of the floating block 34 at the initial position and has the same height, and the reason that the appearance size of the fourth drain hole 27 is larger than that of the third drain hole 22 is to increase the drainage speed of the fourth drain hole 27; when the square water container 21 is filled with rainwater and the whole floating block 34 is positioned in the rainwater, the buoyancy force applied to the floating block 34 is the largest; at this time, the floating block 34 makes the guide block 35 slide upwards along the trigger groove 29 with a very high instantaneous acceleration against the limit of the limit block 37 under the action of the floating force, and the reset plate spring 73 is stretched; the guide block 35 drives the first rack 36 to move upwards; the first rack 36 drives the second gear 49 to rotate through the first gear 41, the first one-way clutch 42, the first transmission shaft 43, the first bevel gear 44, the second bevel gear 45 and the second transmission shaft 46; the second one-way clutch 72 does not obstruct the first transmission shaft 43 at this time; the cylindrical water container 31 is also filled with rainwater; the third gear 50 slides down the first pin 53 and engages with the second gear 49 and the second rack 57 by the gravity of the rainwater in the cylindrical water container 31; the first return spring 52 is compressed; the second gear 49 drives the third gear 50 to rotate; the third gear 50 rotates the support plate 54 and the first return spring 52 together through three first pins 53; the third gear 50 drives the dust removing strip 62 to slide along the bottom surface of the lampshade 15 through the second rack 57, the connecting rod 58, the pressure rod 59, the telescopic outer sleeve 60 and the telescopic inner rod 61; the second return spring 64 is stretched and the dusting operation of the dusting strip 62 is started; meanwhile, the first rack 36 drives the baffle 40 to move upwards through the L-shaped connecting rod 39; the fourth drain hole 27 is opened; rainwater in the square water container 21 and the trigger cavity 26 is quickly drained; the buoyancy force applied to the floating block 34 disappears, and under the action of the reset plate spring 73, the first rack 36 drives the guide block 35, the floating block 34, the L-shaped connecting rod 39 and the baffle 40 to move downwards together to return to the initial position; the baffle 40 blocks the fourth drain hole 27 again; the rotation of the first rack 36 drives the first gear 41 to rotate, and the first gear 41 does not drive the first transmission shaft 43 to rotate reversely through the first one-way clutch 42; the first transmission shaft 43 does not rotate reversely due to the second one-way clutch 72; the first bevel gear 44, the second bevel gear 45, the second transmission shaft 46, the second gear 49 and the third gear 50 do not rotate reversely; the second rack 57 is to be in place not to slide back to the initial position under the action of the second return spring 64; since the lower end surface of the fourth drain hole 27 is flush with and level with the lower end surface of the floating block 34 at the initial position, when the rainwater level in the water square container 21 and the trigger chamber 26 drops to be flush with the fourth drain hole 27, the rainwater level does not drop; at this point, the float 34 just falls back to the initial position and just touches the water surface and there is no buoyancy; the time required when the water tank 21 is filled again is shorter than the time required when the water tank is filled with rainwater for the first time, so that the time interval of the movement of the dust removing strip 62 in the same direction is shortened.

The specific implementation mode is as follows: when raining, the square water container 21 is filled with rainwater, the whole floating block 34 is positioned in the rainwater, and the buoyancy force borne by the floating block 34 is the largest; at this time, the floating block 34 makes the guide block 35 slide upwards along the trigger groove 29 with a very high instantaneous acceleration against the limit of the limit block 37 under the action of the floating force, and the reset plate spring 73 is stretched; the guide block 35 drives the first rack 36 to move upwards; the first rack 36 drives the second gear 49 to rotate through the first gear 41, the first one-way clutch 42, the first transmission shaft 43, the first bevel gear 44, the second bevel gear 45 and the second transmission shaft 46; the second one-way clutch 72 does not obstruct the first transmission shaft 43 at this time; the cylindrical water container 31 is also filled with rainwater; the third gear 50 slides down the first pin 53 and engages with the second gear 49 and the second rack 57 by the gravity of the rainwater in the cylindrical water container 31; the first return spring 52 is compressed; the second gear 49 drives the third gear 50 to rotate; the third gear 50 rotates the support plate 54 and the first return spring 52 together through three first pins 53; the third gear 50 drives the dust removing strip 62 to slide along the bottom surface of the lampshade 15 through the second rack 57, the connecting rod 58, the pressure rod 59, the telescopic outer sleeve 60 and the telescopic inner rod 61; the second return spring 64 is stretched and the dusting operation of the dusting strip 62 is started; meanwhile, the first rack 36 drives the baffle 40 to move upwards through the L-shaped connecting rod 39; the fourth drain hole 27 is opened; rainwater in the square water container 21 and the trigger cavity 26 is quickly drained; the buoyancy force applied to the floating block 34 disappears, and under the action of the reset plate spring 73, the first rack 36 drives the guide block 35, the floating block 34, the L-shaped connecting rod 39 and the baffle 40 to move downwards together to return to the initial position; the baffle 40 blocks the fourth drain hole 27 again; the rotation of the first rack 36 drives the first gear 41 to rotate, and the first gear 41 does not drive the first transmission shaft 43 to rotate reversely through the first one-way clutch 42; the first transmission shaft 43 does not rotate reversely due to the second one-way clutch 72; the first bevel gear 44, the second bevel gear 45, the second transmission shaft 46, the second gear 49 and the third gear 50 do not rotate reversely; the second rack 57 is to be in place not to slide back to the initial position under the action of the second return spring 64.

When the square water container 21 is filled with rainwater quickly again, the whole floating block 34 is positioned in the rainwater, and the buoyancy force applied to the floating block 34 is the maximum; at this time, the floating block 34 makes the guide block 35 slide upwards along the trigger groove 29 with a very high instantaneous acceleration against the limit of the limit block 37 under the action of the floating force, and the reset plate spring 73 is stretched; the guide block 35 drives the first rack 36 to move upwards; the first rack 36 drives the second gear 49 to rotate through the first gear 41, the first one-way clutch 42, the first transmission shaft 43, the first bevel gear 44, the second bevel gear 45 and the second transmission shaft 46; the second one-way clutch 72 does not obstruct the first transmission shaft 43 at this time; the second gear 49 drives the third gear 50 to rotate; the third gear 50 rotates the support plate 54 and the first return spring 52 together through three first pins 53; the third gear 50 drives the dust removing strip 62 to continuously slide along the bottom surface of the lampshade 15 on the basis of the first sliding through the second rack 57, the connecting rod 58, the pressure rod 59, the telescopic outer sleeve 60 and the telescopic inner rod 61; the second return spring 64 is further stretched; meanwhile, the first rack 36 drives the baffle 40 to move upwards through the L-shaped connecting rod 39; the fourth drain hole 27 is opened; rainwater in the square water container 21 and the trigger cavity 26 is quickly drained; the buoyancy force applied to the floating block 34 disappears, and under the action of the reset plate spring 73, the first rack 36 drives the guide block 35, the floating block 34, the L-shaped connecting rod 39 and the baffle 40 to move downwards together to return to the initial position; the baffle 40 blocks the fourth drain hole 27 again; the rotation of the first rack 36 drives the first gear 41 to rotate, and the first gear 41 does not drive the first transmission shaft 43 to rotate reversely through the first one-way clutch 42; the first transmission shaft 43 does not rotate reversely due to the second one-way clutch 72; the first bevel gear 44, the second bevel gear 45, the second transmission shaft 46, the second gear 49 and the third gear 50 do not rotate reversely; the second rack 57 is to be in place not to slide back to the initial position under the action of the second return spring 64; the rainwater in the water square container 21 and the trigger chamber 26 is repeatedly filled and emptied; the dusting strips 62 continue to slide in the same direction; until the dust removing bar 62 moves to the other end of the lamp housing 15, the second bar 57 is disengaged from the third gear 50 and is not engaged, and the second bar 57 is left to be stationary by the third gear 50 under the pulling force of the second return spring 64.

When the rain stops, the rainwater in the cylindrical water container 31, the square water container 21 and the trigger groove 29 is emptied; the gravity of the rainwater acting on the upper end surface of the third gear 50 disappears; the third gear 50 moves back up to the initial position by the restoring force of the first return spring 52, and at the same time, the third gear 50 is separated from the second rack 57 and the second gear 49; under the restoring force of the second return spring 64, the connecting rod 58 drives the second rack 57 to return to the initial position; the connecting rod 58 drives the dedusting strip 62 to reversely slide along the bottom surface of the inner wall of the lampshade 15 through the pressure rod 59, the telescopic outer sleeve 60 and the telescopic inner rod 61 and returns to the initial position; under the action of the reset plate spring 73, the first rack 36 drives the first gear 41 to rotate and simultaneously drives the baffle 40, the guide block 35 and the floating block 34 to return to the initial position, and the baffle 40 blocks the fourth drain hole 27 again; in the whole rain process, the dust removing strip 62 continuously slides along the same direction all the time; when the rain stops, the dust removal strip 62 slides toward the initial position by the second return spring 64.

In conclusion, the invention has the beneficial effects that: the dust removing strip 62 returns once in the whole rain process, so that the dust in the lampshade 15 is cleaned, and meanwhile, the dust cleaned by the dust removing strip 62 is washed clean by the water discharged from the square water container 21 and the cylindrical water container 31, so that the dust removing effect in the lampshade 15 is better; the dust removal of the whole street lamp is realized by utilizing rainwater, so that the dust removal cost of the street lamp is saved, and the potential safety hazard caused by manual dust removal is avoided.
