Example 1
Referring to fig. 1-3, a self-cleaning type LED street lamp includes a lamp post 1 and a lampshade 2 fixedly connected to an upper end of the lamp post 1, the lower end of the lampshade 2 is open and provided with a transparent cover 4, a lamp body 3 is fixedly mounted between inner walls of the lampshade 2, sliding plug cylinders 6 are fixedly connected to opposite side walls of the lampshade 2, magnetic sliding plugs 9 are hermetically and slidably connected in the sliding plug cylinders 6, the magnetic sliding plugs 9 divide the interior of the sliding plug cylinders 6 into two cavities, and an evaporation liquid is filled in one of the cavities.
Furthermore, the sliding plug cylinder 6 is transparent, so that heat in sunlight can be better transferred to the evaporating liquid, the evaporating liquid is butyl acetate, the boiling point of the butyl acetate is 26.5 ℃, and the evaporating liquid can absorb heat to reach the boiling point temperature in spring, summer and autumn under the irradiation of the sunlight, so that the evaporating liquid is converted into a gaseous state, and the air pressure in the cavity where the evaporating liquid is located is increased.
The side wall of the sliding plug cylinder 6 is fixedly connected with a protective cover 10 corresponding to the position of the evaporated liquid, the side wall of the protective cover is rotatably connected with an axial fan 11 through a rotating shaft, the rotating shaft extends into the protective cover 10 and is coaxially and fixedly connected with a dynamic friction disc 12, a fixed friction disc 13 in contact with the dynamic friction disc 12 is fixedly connected between the inner walls of the protective cover 10, a heat conduction plate 8 in contact with the evaporated liquid is embedded in the side wall of the sliding plug cylinder 6 corresponding to the protective cover 10, and a wiping mechanism for wiping the surface of the transparent cover 4 is installed between the opposite side walls of the two sliding plug cylinders 6.
Furthermore, the dynamic friction disc 12 and the static friction disc 13 are both made of elastic materials and are tightly abutted, so that the situation that the dynamic friction disc and the static friction disc cannot be continuously contacted and rubbed due to abrasion after being used for a period of time does not occur.
The wiping mechanism comprises two first permanent magnets 5 which are respectively connected to the opposite side walls of the two sliding plug cylinders 6 in a sliding mode, a cleaning brush 7 is fixedly connected between the opposite side walls of the two first permanent magnets 5, and the surface of the cleaning brush 7 is attached to the surface of the transparent cover 4.
The different poles of the magnetic sliding plug 9 and the first permanent magnet 5 close to the magnetic sliding plug are opposite, so that attraction force is generated between the magnetic sliding plug 9 and the first permanent magnet 5, meanwhile, the sliding plug cylinder 6 is made of non-magnetic shielding materials, and the sliding of the magnetic sliding plug 9 can drive the first permanent magnet 5 to synchronously slide.
It should be noted that the inner wall of the cavity in which the non-evaporative liquid is located in the sliding plug cylinder 6 is provided with an air hole communicated with the outside for maintaining a constant pressure and avoiding blocking the sliding of the magnetic sliding plug 9.
In this embodiment, in the time of the higher air temperature in spring, summer and autumn, sunshine shines on sliding plug section of thick bamboo 6 for the evaporation liquid heat absorption evaporation is gaseous, thereby makes the increase of atmospheric pressure in its place cavity, promotes the slip of magnetism sliding plug 9, and the slip of magnetism sliding plug 9 drives and slides in step with the first permanent magnetism piece 5 that is close to rather than, thereby drives cleaning brush 7 horizontal displacement, cleans the translucent cover 4 surface, strikes off translucent cover 4 surface dust, improves the illumination performance of street lamp.
When the temperature is lower in winter, the evaporating liquid can not reach the boiling point temperature only by the air temperature, but the general wind power in winter is larger, the axial fan 11 can be driven by the air flow to rotate continuously, thereby driving the dynamic friction disc 12 to rotate continuously, and generating friction with the fixed friction disc 13, and further generating a large amount of heat, the heat is transferred to the evaporating liquid through the heat conduction plate 8, and the evaporating liquid can be heated and evaporated into gas, thereby driving the cleaning brush to move horizontally through the magnetic sliding plug 9 and the first permanent magnet block 5, wiping the surface of the transparent cover 4, scraping the dust on the surface of the transparent cover 4, and improving the lighting performance of the street lamp.
When the temperature is reduced in the evening or the wind power is reduced in the day in winter, the temperature of the evaporating liquid is reduced and liquefied, negative pressure is generated in the cavity where the evaporating liquid is located, the magnetic sliding plug 9 is reset, and in the process, the first permanent magnet block 5 and the cleaning brush 7 are driven to horizontally displace once again, namely, the surface of the transparent cover 4 is wiped once again.
