[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-9 , a technical solution provided by an embodiment of the present invention: the smart LED street lamp for city use includes a lamp pole 1, a transmission component, a linkage component and an adjustment component. A crossbeam 2 is provided on the top of the lamp pole 1, and a storage groove 30 is provided at the bottom of the crossbeam 2. A lamp head 4 is vertically slidably connected in the storage groove 30, and a baffle 16 is horizontally slidably connected in the crossbeam 2. During the process of the baffle 16 sliding horizontally toward the storage groove 30, a blocking position for blocking the storage groove 30 is provided. A cleaning nozzle 5 is horizontally rotatably connected to the bottom of the crossbeam 2. The transmission component receives the forward rotation drive of the cleaning nozzle 5 to make the lamp head 4 reciprocate in the vertical direction. The linkage component receives the upward movement drive of the lamp head 4 to make the baffle 16 slide toward the storage groove 30. During the reverse movement of the cleaning nozzle 5, The adjusting component drives the cleaning nozzle 5 to slide vertically. Specifically, when the lamp head 4 is working, the lamp head 4 can be cleaned by reversing the cleaning nozzle 5 to improve the lighting effect of the lamp head 4, and the vertical position of the lamp head 4 can be adjusted by the adjusting component to expand the cleaning range of the cleaning nozzle 5. When the lamp head 4 is switched to the off state, the cleaning nozzle 5 is rotated forward, and the lamp head 4 is driven to move up and be stored in the beam 2 through the transmission component. At the same time, the baffle 16 is driven horizontally by the linkage component to seal the storage groove 30 to prevent stains from entering the storage groove 30 and contaminating the lamp head 4, thereby increasing the service life of the lamp head 4 and preventing the lamp head 4 from being exposed to the outside and being damaged. At the same time, the cleaning nozzle 5 continues to be reversed from time to time, and the water droplets sprayed by the cleaning nozzle 5 can increase the humidity in the air.

[0030] As a preferred technical solution, the transmission assembly includes a ratchet 6, a turntable 7, a pawl 8, a rotating shaft 9, a torsion spring 10, a connecting plate 11, a rotating rod 12, a first slider 13 and a bracket 18. The ratchet 6 and the turntable 7 are horizontally rotatably connected in the crossbeam 2, the rotating shaft 9 is vertically arranged at the top of the turntable 7, the pawl 8 is rotatably sleeved on the rotating shaft 9, and the torsion spring 10 is arranged between the pawl 8 and the rotating shaft 9. When the ratchet 6 rotates forward, the pawl 8 abuts against the ratchet 6, and the rotating rod 12 is coaxially fixed to the bottom end of the turntable 7. The first slider 13 is vertically slidably sleeved on the rotating rod 12. The bottom of the first slider 13 is fixedly connected to the lamp head 4, the connecting plate 11 is fixedly connected to the top of the ratchet 6, the connecting plate 11 is fixedly connected to the bracket 18, and the cleaning nozzle 5 is vertically slidably connected in the bracket 18. Specifically, a motor 3 is provided at the top of the crossbeam 2, and the output end of the motor 3 It is coaxially fixedly connected to the top of the ratchet 6. When the lamp head 4 is working, starting the motor 3 can drive the ratchet 6 to reverse. The pawl 8 is always slidably fitted with the ratchet teeth of the ratchet 6 under the action of the torsion spring 10, and does not drive the pawl 8 to rotate. Through the connecting plate 11 and the bracket 18, the cleaning nozzle 5 is driven to rotate, and the lamp head 4 is cleaned 360°, which can improve the lighting effect of the lamp head 4. When the lamp head 4 is in the closed state, starting the motor 3 can drive the ratchet 6 to rotate forward, and the ratchet teeth of the ratchet 6 abut against the pawl 8, pushing the pawl 8 to rotate. At the same time, the pawl 8 drives the turntable 7 to rotate through the rotating shaft 9, and the turntable 7 drives the rotating rod 12 to rotate, so as to drive the first slider 13 to move vertically upward along the length direction of the rotating rod 12, and the first slider 13 drives the lamp head 4 to move upward and move into the beam 2, so as to avoid the lamp head 4 being exposed to the outside and damaged, thereby improving the service life of the lamp head 4.

[0031] As a preferred technical solution, two spiral grooves 14 connected end to end are symmetrically provided on the rotating rod 12, and a protrusion is provided in the first slider 13, which slides with the two spiral grooves 14 in turn, and a third slide groove 28 is vertically provided in the crossbeam 2, and the first slider 13 is slidably connected in the third slide groove 28. Specifically, through the cooperation between the protrusion and the spiral groove 14, the third slide groove 28 limits the axial rotation of the first slider 13, and the first slider 13 is driven to move along the length direction of the rotating rod 12 through the spiral transmission. The ratchet 6 rotates half a circle forward, and the lamp head 4 can be stored in the crossbeam 2, which improves the storage speed. When the lamp head 4 needs to work, the ratchet 6 can be rotated half a circle forward again to expose the lamp head 4 to illuminate the bottom.

[0032] As a preferred technical solution, the linkage assembly includes a connecting rod 15, and a hinge seat is provided on the top of the baffle 16 and one side of the first slider 13. The two ends of the connecting rod 15 are respectively hinged to the two hinge seats, and a second slide groove 25 is horizontally opened in the crossbeam 2. The baffle 16 is horizontally slidably connected in the second slide groove 25. Specifically, the first slider 13 moves upward, driving one end of the connecting rod 15 to move upward. Since the second slide groove 25 limits the vertical displacement of the baffle 16, the other end of the rocker arm 20 can only move horizontally, so that the rocker arm 20 drives the baffle 16 to move toward the lamp head 4 to block the storage groove 30. When the baffle 16 is at the blocking position, the baffle 16 is located directly below the lamp head 4, which can prevent stains from entering the storage groove 30 and contaminating the lamp head 4, thereby improving the service life of the lamp head 4.

[0033] As a preferred technical solution, the adjustment component includes a bevel gear ring 17, a bevel gear 19 meshing with the bevel gear ring 17, a rocker arm 20, a first connecting column 21, a second slider 22 and a second connecting column 26. The bevel gear ring 17 is arranged on the side of the baffle 16 close to the cleaning nozzle 5, the bevel gear 19 is rotatably connected in the crossbeam 2, the first connecting column 21 is arranged at one end of the bevel gear 19 close to the cleaning nozzle 5, the second slider 22 is vertically slidably connected in the bracket 18, the cleaning nozzle 5 is inserted in the second slider 22, the second connecting column 26 is arranged on the side of the second slider 22 close to the bevel gear 19, and the two ends of the rocker arm 20 are rotatably sleeved with the first connecting column 21 and the second connecting column 26 respectively. Specifically, when the lamp holder 4 is working, the baffle 16 moves to the far side. The cleaning nozzle 5 is away from the lamp holder 4, and when the ratchet 6 reverses to drive the cleaning nozzle 5 to clean the lamp holder 4, the bracket 18 drives the second slider 22 to rotate, and the second slider 22 drives the bevel gear 19 to revolve through the rocker arm 20, and when the bevel gear 19 is engaged with the bevel gear ring, the bevel gear 19 rotates, and the end of the rocker arm 20 that is connected to the first connecting column 21 rotates along with the bevel gear 19, and the other end of the rocker arm 20 drives the second slider 22 to move vertically, which can change the vertical position of the cleaning nozzle 5, thereby expanding the cleaning range and improving the cleaning effect of the lamp holder 4. The transmission ratio of the helical gear ring 17 and the bevel gear 19 is 1:2, and the ratchet 6 can be reversed for multiple turns to intermittently change the vertical position of the cleaning nozzle 5, so that the cleaning range of the lamp holder 4 is wider.

[0034] As a preferred technical solution, a first slide groove 23 is vertically opened in the bracket 18, and the second slider 22 is vertically slidably connected to the first slide groove 23, and a guide groove 27 communicating with the first slide groove 23 is vertically opened in the bracket 18. A guide rod 24 is vertically provided on the top of the second slider 22, and the guide rod 24 is slidably connected in the guide groove 27. Specifically, through the sliding cooperation between the guide groove 27 and the guide rod 24, the second slider 22 only moves in the vertical direction, thereby improving the cleaning effect of the cleaning nozzle 5.

[0035] As a preferred technical solution, a socket is provided in the second slider 22, and a rubber ring is provided on the inner wall of the socket. The cleaning nozzle 5 is inserted into the rubber ring. Specifically, the setting of the rubber ring can play a shock-absorbing role, which can absorb the vibration and impact generated when the cleaning nozzle 5 is working, protect the safety and stable operation of the equipment, and prevent the cleaning nozzle 5 from falling. The rubber ring can also play a buffering role, alleviate the friction and noise generated when the cleaning nozzle 5 is working, and ensure the smooth operation of the equipment.

[0036] As a preferred technical solution, a plurality of through holes 29 are provided in a circular array in the crossbeam 2, and each through hole 29 is located between the lamp head 4 and the cleaning nozzle 5. Specifically, through the arrangement of each through hole 29, the water droplets sprayed by the cleaning nozzle 5 can be refined, which can further expand the cleaning range, save water to a certain extent, reduce the spraying cost, and prevent mosquitoes from drilling into the equipment.

[0037] Working principle: When the lamp holder 4 is working, the motor 3 is started to drive the ratchet 6 to reverse. The pawl 8 is always in sliding contact with the ratchet teeth of the ratchet 6 under the action of the torsion spring 10, and does not drive the pawl 8 to rotate. The cleaning nozzle 5 is driven to rotate through the connecting plate 11 and the bracket 18, and the lamp holder 4 is cleaned 360 degrees, which can improve the lighting effect of the lamp holder 4. The bracket 18 drives the second slider 22 to rotate, and the second slider 22 drives the bevel gear 19 to revolve through the rocker 20. When the bevel gear 19 is aligned with the bevel gear 19, the bevel gear 19 rotates. When the gear ring is engaged, the bevel gear 19 rotates, and the end of the swing rod 20 that is sleeved with the first connecting column 21 rotates along with the bevel gear 19. The other end of the swing rod 20 drives the second slider 22 to move vertically, which can change the vertical position of the cleaning nozzle 5, thereby expanding the cleaning range and improving the cleaning effect of the lamp head 4. The ratchet 6 can be reversed for multiple turns to intermittently change the vertical position of the cleaning nozzle 5, thereby widening the cleaning range of the lamp head 4. When the lamp head 4 is in the off state, the motor 3 can be started to drive The movable ratchet 6 rotates forward, and the ratchet teeth of the ratchet 6 abut against the pawl 8, pushing the pawl 8 to rotate. At the same time, the pawl 8 drives the turntable 7 to rotate through the rotating shaft 9, and the turntable 7 drives the rotating rod 12 to rotate, so as to drive the first slider 13 to move vertically upward along the length direction of the rotating rod 12, and the first slider 13 drives the lamp head 4 to move upward and move into the crossbeam 2 to prevent the lamp head 4 from being exposed to the outside and damaged. The first slider 13 moves upward, driving one end of the connecting rod 15 to move upward. Since the second slide groove 25 limits the baffle 16 in the vertical direction The displacement of the swing arm 20 makes the other end of the swing arm 20 only able to move horizontally, so that the swing arm 20 drives the baffle 16 to move toward the lamp head 4 to block the storage groove 30. When the baffle 16 is at the blocking position, the baffle 16 is located directly below the lamp head 4, which can prevent stains from entering the storage groove 30 and contaminating the lamp head 4, thereby increasing the service life of the lamp head 4. At the same time, the cleaning nozzle 5 continues to be reversed from time to time. The cleaning nozzle 5 can increase the humidity in the air and suppress dust, thereby preventing dead leaves from spontaneous combustion and pedestrians from inhaling dust.
