The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] Example 1: Please refer to Figures 1-19 Structural diagram; the present invention provides the following technical solution:

[0049] Specifically, it refers to a wide-angle LED street light, including a mounting bracket 1, a fixing sleeve 2, and a lamp housing 3. The mounting bracket 1 and the lamp housing 3 are respectively installed on the top and bottom of the fixing sleeve 2. An LED lamp head 4 is installed on the top of the lamp housing 3 through a lamp holder. A transparent lamp cover 5 is threadedly connected to the bottom of the lamp housing 3. The transparent lamp cover 5 fits with the lamp housing 3 and is a semi-circular ring that is longitudinally cut. Two external threaded sleeves are fixed on the top of the transparent lamp cover 5. Two annular internal threaded grooves that fit with the external threaded sleeves are opened on the bottom of the lamp housing 3. The transparent lamp cover 5 and the lamp housing 3 are connected by threads, which ensures the connection is sealed and facilitates replacement and maintenance.

[0050] A water collection cylinder 6 is rotatably installed inside the fixed sleeve 2. The top of the water collection cylinder 6 extends to the top of the fixed sleeve 2 and is fixed with a water collection cover 7. The inner cavity of the water collection cover 7 is connected to the inner cavity of the water collection cylinder 6. A first drive blade 8 and a second drive blade 9 are fixed on the outer surface of the water collection cover 7. The first drive blade 8 and the second drive blade 9 drive the water collection cylinder 6 and the water collection cover 7 to rotate under the push of external wind. Inside the water collection cover 7, from top to bottom, a filter screen 34 and a filter cotton 35 are installed. The filter screen 34 is preferably a nano-silver filter screen, and the filter cotton 35 is preferably an antibacterial filter cotton, which can disinfect and sterilize rainwater, ensuring the cleanliness and hygiene of the rainwater and making it more environmentally friendly.

[0051] The top of the mounting bracket 1 is fixed with a conical support cover 32 that mates with the water collection cover 7. Bearings 33 for supporting the water collection cover 7 are installed at both the bottom and top of the conical support cover 32. A driving clearance is provided between the inner surface of the conical support cover 32 and the outer surface of the water collection cover 7 to mate with the second drive blade 9. This provides support for the water collection cover 7, reduces friction between structural components, and ensures that the water collection cylinder 6 and the water collection cover 7 can rotate under wind force.

[0052] The water collection cylinder 6 has a piston disc 10 that mates with it. A support frame 11 is fixed to the bottom of the water collection cylinder 6. A spring 12 is installed at the center of the top of the support frame 11, with its top end pressed against the bottom of the piston disc 10. A water-retaining ring 13 with the same center as the piston disc 10 is installed inside the piston disc 10. A water outlet hole 14 is opened at the bottom edge of the piston disc 10, penetrating the piston disc 10 and communicating with the inner cavity of the piston disc 10. An adjusting column 15 passes through the piston disc 10, and the length of the adjusting column 15 is greater than the length of the spring 12 after compression. The water-retaining ring 13 inside the piston disc 10 is lifted before the spring 12 is fully compressed, ensuring that rainwater can smoothly enter the hollow cleaning plate 18 through the water outlet 14. The top of the adjusting column 15 is fixed with a mounting frame 16, which is filled with an absorbent sponge 17. The absorbent sponge 17 is an antibacterial sponge, and its weight when fully soaked with water, plus the weight of the structure applied to the top of the spring 12, can offset the elongation of the spring 12. The bottom outer surface of the mounting frame 16 is fixedly connected to the water-retaining ring 13 through a connecting rod.

[0053] Several hollow cleaning plates 18 are fixedly connected to the bottom of the piston disc 10. These hollow cleaning plates 18 are not only small in width and have sufficiently large gaps between adjacent plates, but they are also close to the transparent lampshade 5. Therefore, they have minimal impact on streetlight illumination during cleaning. The inner cavity of each hollow cleaning plate 18 is connected to the water outlet 14. Cleaning bristles are installed on the surface of each hollow cleaning plate 18 facing the inner wall of the water collection tank 6, and water spray holes are opened on the same surface. A sleeve is fitted onto the bottom outer surface of the lamp housing 3, corresponding to the hollow cleaning plates 18. The magnetic adsorption ring 19 is matched with the support frame 11, which has a through hole 20 that matches the hollow cleaning plate 18. The through hole 20 is also arc-shaped and is concentric with the transparent lampshade 5. The transparent lampshade 5 matches the lamp housing 3 and is a semi-circular ring that is longitudinally cut. The top of the transparent lampshade 5 is fixed with two external thread sleeves. The bottom of the lamp housing 3 has two annular internal thread grooves that match the external thread sleeves. The bottom section of the water collection tube 6 is an outwardly spreading arc shape. The arc shape of the bottom section of the water collection tube 6 is concentric with the lamp housing 3 and the transparent lampshade 5.

[0054] When a certain amount of rainwater accumulates in the water collection cylinder 6, it will compress the spring 12 at the bottom of the piston disc 10, causing the piston disc 10 to move downwards. This will cause the hollow cleaning plate 18, which is fixed at the bottom of the piston disc 10, to move downwards. The hollow cleaning plate 18 extends to the bottom of the water collection cylinder 6 through the through hole 20. Under the action of the arc-shaped through hole 20 and the arc at the bottom of the water collection cylinder 6, the part extending out of the water collection cylinder 6 will bend. Since the hollow cleaning plate 18 is made of elastic and magnetic metal, with the magnetic attraction of the magnetic adsorption ring 19, the hollow cleaning plate 18 will match the transparent lampshade 5 at a certain arc. At this time, the cleaning bristles on the hollow cleaning plate 18 will contact the transparent lampshade 5. Meanwhile, since the water collection tube 6 is fixedly connected to the support frame 11, when the external wind blows, the water collection tube 6 rotates and drives the support frame 11 to rotate. The hollow cleaning plate 18 passes through the support frame 11 through the through hole 20. Therefore, the rotation of the support frame 11 will also drive the hollow cleaning plate 18 to rotate. At this time, the cleaning brush bristles can be used to clean the transparent lampshade 5 by the rotation of the hollow cleaning plate 18.

[0055] When enough water accumulates in the water collection cylinder 6 (the water-absorbing sponge 17 is fully saturated), the water collection cylinder 6 moves downward to its limit (the weight of the water-absorbing sponge 17 fully saturated with water can offset the deformation of the spring 12, so that the amount set by the spring 12 is fully compressed). At this time, the adjusting column 15 is lifted, causing the water outlet 14, which is sealed by the water-blocking ring 13, to leak out. The filtered rainwater can enter the hollow cleaning plate 18 through the water outlet 14 and be sprayed out through the spray holes on the hollow cleaning plate 18 to rinse the transparent lampshade 5. The cleaning brush rotates while brushing, improving the cleaning effect of the transparent lampshade 5. It does not require the consumption of electricity and water resources, making it energy-saving and environmentally friendly.

[0056] When the water in the water collection tank 6 is depleted, the spring 12 is constrained by the water-absorbing sponge 17, which is saturated with water. At this time, the piston disc 10 is not lifted. As the water collection tank 6 rotates, the water in the water-absorbing sponge 17 is thrown out under the action of centrifugal force and enters the hollow cleaning plate 18 through the water outlet 14 to clean the transparent lampshade 5. As the water in the water-absorbing sponge 17 is thrown out, the piston disc 10 is gradually lifted. At the same time, the hollow cleaning plate 18 begins to retract into the water collection tank 6, and the adjusting column 15 also gradually falls down until the adjusting column 15 falls completely. The water-blocking ring 13 contacts the bottom of the piston disc 10, completing the sealing of the water outlet 14 and preventing rainwater from being injected into the hollow cleaning plate 18. The above process continues with the entry of rainwater filtered by the filter screen 34 and filter cotton 35 until the rainwater stops entering.

[0057] When the rain stops entering, as the rainwater in the absorbent sponge 17 is gradually discharged and evaporated, the piston disc 10 will rise to the top, and the hollow cleaning plate 18 will completely retract into the water collection cylinder 6, while the bottom part of the hollow cleaning plate 18 will still be located in the through hole 20, waiting for the next water collection cylinder 6 to be used for cleaning.

[0058] Example 2: Based on Example 1, the difference in this example is as follows:

[0059] like Figures 1-4 As shown in Figures 13-19, the system also includes a dust cover 21 and a drive gear 22. The drive gear 22 is sleeved on the outer circular surface of the top of the water collection cylinder 6. The dust cover 21 is sleeved on the outside of the fixed sleeve 2 and is fixedly connected to the mounting bracket 1 by screws. Sufficient space is left between the inner wall of the dust cover 21 and the outer wall of the fixed sleeve 2 to form a transmission chamber 23. The dust cover 21 has a ventilation window with a dustproof net to facilitate the entry of outside air into the transmission chamber 23, so that the air pump 31 can draw in air when working.

[0060] A reciprocating screw 24 is installed inside the transmission chamber 23. The top and bottom ends of the reciprocating screw 24 are rotatably connected to the bottom of the mounting bracket 1 and the top of the lamp housing 3, respectively. A driven gear 25 is fixedly sleeved on the reciprocating screw 24. The driven gear 25 passes through the fixed sleeve 2 and meshes with the drive gear 22. A drive block 26 is sleeved on the reciprocating screw 24 and is connected to the reciprocating screw 24. A connecting plate is fixed on one surface of the drive block 26.

[0061] An annular air delivery groove 27 is provided at the top of the lamp housing 3 and inside the transmission chamber 23. Several air guide channels 28 are provided in the lamp housing 3. The air inlet end of the air guide channel 28 is connected to the annular air delivery groove 27. The air outlet end of the air guide channel 28 is located at the bottom end face of the lamp housing 3. An exhaust valve 29 is installed at the air outlet end of the air guide channel 28. An arc-shaped air outlet pipe with the same center as the transparent lamp cover 5 is installed at the exhaust end of the exhaust valve 29. The arc-shaped air outlet pipe can play a guiding role, so that clean air can be sprayed along the outer surface of the transparent lamp cover 5 for cleaning. A secondary air outlet is provided on the outer circular surface of the air outlet pipe facing the transparent lamp cover 5. Multiple air outlets can spray air to clean the transparent lamp cover 5 from multiple angles, thereby ensuring the air spray cleaning effect of the transparent lamp cover 5.

[0062] An annular concave sealing cover 30, which mates with the annular air supply groove 27, is fixed to the top of the lamp housing 3 and inside the transmission chamber 23 by screws. An air pump 31 is fixed to the top of the annular concave sealing cover 30 (in this application, multiple sets of air pumps 31 can be set to improve inflation efficiency). The air outlet of the air pump 31 is connected to the inner cavity of the annular concave sealing cover 30 through an air supply hose. The piston rod of the air pump 31 is fixedly connected to the drive block 26 through a connecting plate.

[0063] Compared to Embodiment 1, in this embodiment, the surface of the transparent lampshade 5 can be cleaned as long as there is wind blowing across the street lamp, regardless of whether there is rain or not. In the absence of rain but with wind, when the wind drives the water collection cylinder 6 to rotate through the first drive blade 8 and the second drive blade 9, the drive gear 22, which is fixedly installed on the water collection cylinder 6, also rotates. This rotation, through the meshing of the drive gear 22 and the driven gear 25, drives the reciprocating screw 24 to rotate. The reciprocating screw 24 drives the drive block 26 on it to reciprocate. Since the drive block 26 is connected to the piston rod of the air pump 31 through the connecting plate, the reciprocating motion of the piston rod of the air pump 31 draws outside air into the air guide channel 28 and the annular concave sealing cover 30 through the air supply hose. When the pressure in the air guide channel 28 and the annular concave sealing cover 30 reaches the threshold set by the exhaust valve 29, the exhaust valve 29 opens. The air in the air guide channel 28 and the annular concave sealing cover 30 acts on the transparent lampshade 5 through the arc-shaped air outlet and the secondary air outlet, cleaning the dust and dirt on it with air jets to ensure the cleanliness of the surface of the transparent lampshade 5.

[0064] In windy or rainy weather, this embodiment is carried out in conjunction with the water spray cleaning of embodiment one, thereby improving the cleaning effect on the surface of the transparent lampshade 5. Furthermore, the air spray cleaning in this embodiment can accelerate the drying of rainwater on the surface of the transparent lampshade 5, prevent it from adsorbing dust, and further improve the cleaning effect.

[0065] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
