Example 1
Referring to fig. 1, a self-cleaning device for an LED street lamp, including a lamp post 1 and a lamp holder 3 fixedly mounted at the top of the lamp post 1 through a connecting frame 2, a lamp body is fixedly mounted at the lower end of the lamp holder 3, a first gear ring 4 is rotatably connected to the lower end of the side wall of the lamp holder 3, a lampshade 5 is fixedly connected to the lower end of the first gear ring 4, a device cavity 6 is formed in the side wall of the upper end of the lamp post 1, a threaded rod 7 is rotatably connected in the device cavity 6, a sliding plug 8 is slidably connected in the device cavity 6 in a sealing manner, the sliding plug 8 is in threaded connection with the threaded rod 7, a gear 15 is coaxially and fixedly connected to the upper end of the threaded rod 7, the gear 15 extends to the outside of the lamp post 1, and the gear 15 is meshed with the first gear ring 4.
It should be noted that, in this embodiment, the connection between the gear 15 and the lamp post 1 is not sealed, so when the sliding plug 8 slides upwards, air at the upper end of the device cavity 6 can be discharged from the gap between the gear 15 and the lamp post 1 without obstructing the movement of the sliding plug 8, and the sliding plug 8 and the device cavity 6 are both designed into a diamond-shaped cross section, which can ensure that the sliding plug 8 does not rotate when moving upwards, so as to generate a force for rotating the threaded rod 7.
A sliding cavity 9 is formed in the ground, a sealing plate 10 is connected in the sliding cavity 9 in a sealing and sliding mode, the sealing plate 10 is elastically connected to the bottom of the sliding cavity 9 through uniformly distributed springs 11, a speed reducing belt 13 is arranged on the ground, the speed reducing belt 13 is fixedly connected with the sealing plate 10 through a sliding rod 12 penetrating into the sliding cavity 9, the lower end portion of the sliding cavity 9 is communicated with the lower end portion of a device cavity 6 through an air guide cavity 14, and a wiping mechanism used for wiping the surface of a lampshade 5 is installed on a lamp holder 3.
Wiping mechanism is including setting up at lamp shade 5 outside and rather than assorted arc pole 17, and the lateral wall fixed connection of connecting rod 16 and lamp stand 3 is passed through to the upper end of arc pole 17, and arc 18 is scraped to the concave arc fixedly connected with arc of arc pole 17, and arc 18 is scraped and is laminated mutually with the surface of lamp shade 5.
In this embodiment, since the LED street lamp is located at a place where attention is needed, which is similar to a place where automobiles need to be decelerated, such as a school, a community, or a curve, the LED street lamp is mostly located with a deceleration strip 13, when an automobile runs through a road beside the street lamp, the deceleration strip 13 and a sealing plate 10 can be pressed down under the action of the self weight of the automobile, the sealing plate 10 squeezes air at the lower end of a sliding cavity 9 into a device cavity 6, so as to push the sliding plug 8 to move up, the sliding plug 8 drives a threaded rod 7 to rotate, the threaded rod 7 drives a gear 15 to rotate, the gear 15 engages with a first gear ring 4 to rotate, the first gear ring 4 drives a lampshade 5 to rotate synchronously, after the automobile runs, the deceleration strip 13 and the sealing plate 10 reset under the elastic force of a spring 11, negative pressure is generated in the sliding cavity 9, so as to pull down the sliding plug 8, so that the threaded rod 7, the gear 15, and the first gear ring 4 all rotate in opposite directions, because the arc scraping strip 18 and the lamp holder 3 are always fixed, when the first gear ring 4 rotates, the arc scraping strip 18 scrapes off dust on the surface of the lampshade 5, so that the surface of the lampshade 5 is kept clean, and the lighting performance of the street lamp is not affected.
Example 2
Referring to fig. 2 to 3, the difference from embodiment 1 is that: fixedly connected with upper end opening and packing have the water tank 19 of water on the lateral wall of lamp pole 1, it has the chamber 21 that catchments of water to open up to have the packing in the lamp stand 3, water tank 19 passes through aqueduct 20 and catchments the chamber 21 intercommunication, install the check valve that only allows water to flow to catchment the chamber 21 from aqueduct 20 in the aqueduct 20, cavity 22 has been seted up in connecting rod 16 and the arc pole 17, cavity 22 and catchment chamber 21 intercommunication, the concave arc face of arc pole 17 all is equipped with the hole 23 of drawing with cavity 22 intercommunication, install the check valve that only allows water to flow to cavity 22 from catchment chamber 21 in the cavity 22, and link 2 cavity setting, link 2 intercommunication catchments chamber 21 and device chamber 6 upper end.
It should be noted that, in this embodiment, in order to ensure that when the sliding plug 8 moves upwards, the air at the upper end of the device cavity 6 can enter the water collecting cavity 21 from the hollow connecting frame 2, the sealing process is required at the sealing position between the gear 15 and the lamp post 1, and a through hole needs to be formed in the gear 15, which is difficult to implement, so that the gear 15 is replaced by a second gear ring 15a which is rotatably connected to the side wall of the lamp post 1 at the same position and is meshed with the first gear ring 4, a disc 24 is fixedly and coaxially connected to the position of the yard line mounting gear 15 on the threaded rod 7, two ends of the disc 24 are respectively and fixedly connected with a first magnetic block 25, two ends of the second gear ring 15a are respectively and fixedly connected with a second magnetic block 26 which has magnetic attraction opposite to the opposite poles of the first magnetic block 25 (as shown in fig. 4), when the threaded rod 7 rotates, through the magnetic action of the first magnetic block 25 and the second magnetic block 26 and the meshing action of the first gear ring 4 and the second gear ring 15a, the same function of driving the first ring gear 4 to rotate as in embodiment 1 can be achieved, and the volume of the device chamber 6 is large, and when the air at the upper end portion enters the water collecting chamber 21, the water in the water collecting chamber 21 can be completely squeezed into the cavity 22.
In this embodiment, when the sliding plug 8 moves up, the air at the upper end of the device cavity 6 is squeezed into the water collecting cavity 21, so that the water in the water collecting cavity 21 is squeezed into the cavity 22, the arc-shaped wiper strip 18 sucks the water in the cavity 22 through the water sucking holes 23, and the moisture state is kept, so that the cleaning effect of the arc-shaped wiper strip 18 is better when the lampshade 5 is wiped, when the sliding plug 8 resets, the upper end of the device cavity 6 generates negative pressure, so that the negative pressure is generated in the water collecting cavity 21, and the water in the water tank 19 is sucked into the water collecting cavity 21 through the water guide pipe 20, so as to supplement the lost water.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
