[0039] During use, the lamp cover 201 rotates to allow the first cleaning component 202 to clean the lamp cover 201, while the second cleaning component 203 slides up and down to clean the outer surface of the lamp post 101.

[0040] Example 2

[0041] Reference Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0042] The bulb holder 102 includes a first fixing ring 102b fixedly connected to the top of the lamp post 101 via a connecting block 102a, and a second fixing ring 102d fixedly connected above the first fixing ring 102b via a fixing rod 102c. The top of the second fixing ring 102d is arc-shaped, and a first sliding groove 102d-1 is provided inside the second fixing ring 102d.

[0043] The connecting block 102a is used to fix the bulb bracket 102 to the lamp post 101. The second fixing ring 102d is used to fix the position of the lamp cover 201. The fixing rod 102c is used to fix the second fixing ring 102d to the first fixing ring 102b and to install the first cleaning brush 202a and make the surface of the first cleaning brush 202a contact the lamp cover 201.

[0044] The bulb 103 is fixedly connected to the center of the second fixing ring 102d.

[0045] The first cleaning component 202 includes a first cleaning brush 202a fixedly connected to the side wall of the fixed rod 102c. The first cleaning brush 202a rotates and contacts the outside of the lamp cover 201. The first cleaning brush 202a brushes over the lamp cover 201 to clean the dust on the lamp cover 201 and ensure the brightness of the street light.

[0046] The lampshade 201 includes a third fixing ring 201a, a fourth fixing ring 201b disposed above the third fixing ring 201a, and a cover 201c connected between the third fixing ring 201a and the fourth fixing ring 201b.

[0047] The third fixed ring 201a has a second slider 201a-1 on its outside and an internal gear 201a-2 on its inside.

[0048] The fourth fixing ring 201b has a first slider 201b-1 on its outer side. The first slider 201b-1 is rotatably connected in the first slide groove 102d-1. The fourth fixing ring 201b has several water outlet holes 201b-2.

[0049] The third fixing ring 201a is rotatably connected to the lamp post 101 via the second slider 201a-1, and the fourth fixing ring 201b is rotatably connected to the bulb bracket 102 via the first slider 201b-1; the lamp cover 201 is rotatably connected to the street light mechanism 100 via the third fixing ring 201a and the fourth fixing ring 201b.

[0050] The cover 201c is used to protect the internal bulb 103. The brightness of the street light can be maintained by cleaning the cover 201c.

[0051] The top inner wall of the lamp post 101 is provided with a second sliding groove 101a, and the second slider 201a-1 is rotatably connected in the second sliding groove 101a. The side wall of the lamp post 101 is provided with a third sliding groove 101b.

[0052] By matching the second slider 201a-1 with the second slide groove 101a, and matching the first slider 201b-1 with the first slide groove 102d-1, the rotation of the cover 201c is made more stable.

[0053] The internal gear 201a-2 is used to drive the housing 201c to rotate, and the water outlet 201b-2 is used to facilitate water outlet of the water pipe assembly 204 for better cleaning of the housing 201c.

[0054] The second cleaning component 203 includes a motor 203a disposed at the bottom of the lamp post 101, a lead screw 203b fixedly connected to the output shaft of the motor 203a, a fourth slider 203c threadedly connected to the lead screw 203b, an external gear 203d fixedly connected to the top of the lead screw 203b, a mounting bracket 203f fixedly connected to the fourth slider 203c via a third slider 203e, and a second cleaning brush 203g fixedly connected to the mounting bracket 203f.

[0055] The third slider 203e is slidably connected in the third slide groove 101b, the second cleaning brush 203g is in slidable contact with the outer wall of the lamp post 101, and the external gear 203d is meshed with the internal gear 201a-2.

[0056] Motor 203a drives lead screw 203b to rotate. The rotation of lead screw 203b drives fourth slider 203c to move up and down, thereby enabling second cleaning brush 203g to clean the outer surface of lamp post 101. At the same time, the rotation of lead screw 203b drives external gear 203d to rotate, and the rotation of external gear 203d drives internal gear 201a-2 to rotate, which in turn drives cover 201c to rotate, so that first cleaning brush 202a cleans lamp cover 201 and water in nozzle 204a flows out, thus cleaning the street light better.

[0057] The third slider 203e is used to connect the second cleaning brush 203g and the fourth slider 203c.

[0058] The cleaning mechanism 200 also includes a water pipe assembly 204 disposed inside the lamp post 101. The water pipe assembly 204 includes a plurality of nozzles 204a, which slide in contact with the upper wall of the fourth fixing ring 201b. The water pipe assembly 204 is used to supply water to the cleaning mechanism 200.

[0059] When the nozzle 204a contacts the fourth fixing ring 201b, the fourth fixing ring 201b blocks the nozzle 204a, preventing water from flowing out. When the cleaning mechanism 200 is activated, the cover 201c rotates, causing the water outlet 201b-2 to rotate below the nozzle 204a, allowing water to flow out and clean the cover 201c and the lamp post 101.

[0060] Furthermore, the control component 104 is sealed in the housing to prevent short circuits and other malfunctions caused by water flow during cleaning.

[0061] Example 3

[0062] Reference Figures 1-11 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0063] The control component 104 includes a bulb power supply 104a, a cleaning brush power supply 104b, and a timer 104c. The bulb power supply 104a, the cleaning brush power supply 104b, and the timer 104c are electrically connected. The bulb power supply 104a controls the brightness of the bulb 103, the cleaning brush power supply 104b controls the switching of the motor 203a, and the timer 104c controls the switching of the bulb power supply 104a and the cleaning brush power supply 104b.

[0064] Timer 104c can be set to trigger different switches at different time periods, thereby controlling the streetlights to operate in two brightness modes (high and low) and the cleaning mechanism 200 to operate.

[0065] The 104A power supply for the streetlight bulb is designed with two circuits. One circuit directly powers the bulb, while the other circuit uses a diode connected in series with the AC power supply to ensure that the bulb is lit only during half a cycle of current, resulting in half the brightness of the bulb in the high-brightness circuit. This allows for the adjustment of the streetlight bulb's brightness.

[0066] For details, please refer to the appendix. Figure 10 and attached Figure 11 Timer 104c can be set to trigger different switches K1 or K2 at different time periods, where K1 controls the street light to operate at low brightness and K2 controls the street light to operate at high brightness.

[0067] When the set time period is met, the normally open contact K1 or K2 of timer 104c closes, the 220V AC power supply is turned on, the coil of contactor KM1 or KM2 is energized, the contactor is attracted, and the three-phase AC power supply is turned on.

[0068] See attached document Figures 1-11As shown, during use, timer 104c turns on bulb 103 and motor 203a, which in turn turns on motor 203a. Motor 203a drives lead screw 203b to rotate, which in turn moves fourth slider 203c up and down, thereby cleaning the outer surface of lamp post 101 with second cleaning brush 203g. At the same time, the rotation of lead screw 203b drives external gear 203d to rotate, which in turn drives internal gear 201a-2 to rotate, which in turn drives cover 201c to rotate, causing first cleaning brush 202a to clean lamp cover 201. When water outlet 201b-2 rotates to below nozzle 204a, water in nozzle 204a flows out, passing over lamp cover 201 and lamp post 101, increasing the cleaning effect.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
