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.

[0022] 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, the rotating rod 12 is coaxially fixedly connected 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 holder 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 with the top end of the ratchet 6. When the lamp holder 4 is working, starting the motor 3 can drive the ratchet 6 to reverse. Under the action of the torsion spring 10, the pawl 8 always slides and fits with the ratchet teeth of the ratchet 6, 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 holder 4 is cleaned 360°, which can improve the lighting effect of the lamp holder 4. When the lamp holder 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 holder 4 to move upward and move into the crossbeam 2, so as to avoid the lamp holder 4 being exposed to the outside and damaged, thereby improving the service life of the lamp holder 4.

[0023] As a preferred technical solution, two spiral grooves 14 connected end to end are symmetrically opened 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 opened 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.

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 displacement of the baffle 16 in the vertical direction, the other end of the swing arm 20 can only move horizontally, so that the swing arm 20 drives the baffle 16 to move toward the lamp holder 4 to block the storage groove 30. When the baffle 16 is located at the blocking position, the baffle 16 is located directly below the lamp holder 4, which can prevent stains from entering the storage groove 30 and contaminating the lamp holder 4, thereby improving the service life of the lamp holder 4.

[0025] 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.

Specifically, when the lamp holder 4 is working, the baffle 16 moves to the farthest position. 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 meshed with the bevel gear ring, the bevel gear 19 rotates, and the end of the rocker arm 20 and the first connecting column 21 that is rotatably sleeved rotates 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 bevel 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.

[0026] 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 set 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.

[0027] 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.

[0028] 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 holder 4 and the cleaning nozzle 5. Specifically, by providing 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.

[0029] Working principle: When the lamp holder 4 is working, the motor 3 is started to drive the ratchet 6 to reverse, and the ratchet 8 is always slidably fitted with the ratchet teeth of the ratchet 6 under the action of the torsion spring 10, without driving the ratchet 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, and the bracket 18 drives the second slider 22 to rotate, and the second slider 22 drives the bevel gear 19 to revolve through the swing rod 20, and when the bevel gear 19 is aligned with the bevel gear 19, the bevel gear 19 is rotated. When the gear ring is meshed, the bevel gear 19 rotates, and one end of the swing rod 20 that is rotatably sleeved with the first connecting column 21 rotates along with the bevel gear 19, and 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 on the lamp head 4. The ratchet wheel 6 can be reversed for multiple turns to intermittently change the vertical position of the cleaning nozzle 5, so as to have a wider cleaning range for 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 rod 20 makes the other end of the swing rod 20 only move horizontally, so that the swing rod 20 drives the baffle 16 to move toward the lamp holder 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 holder 4, which can prevent stains from entering the storage groove 30 to pollute the lamp holder 4, thereby increasing the service life of the lamp holder 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 and suppress dust in the air, thereby preventing dead leaves from spontaneous combustion and pedestrians from inhaling dust.
