Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and more specifically, it relates to a wide-angle LED street lamp. Background Art

[0002] With the acceleration of the urbanization process, street lamps, as an important part of urban infrastructure, have continuously improved their performance and functions. Although traditional LED street lamps have advantages such as energy conservation and environmental protection, during long-term use, their transparent lamp covers are prone to accumulating dust and dirt, affecting the lighting effect. Especially in areas with more rain, water stains and mud stains are likely to remain on the surface of the transparent lamp cover, further reducing the lighting quality. And due to the high height of the street lamps, disassembling and cleaning the lamp covers will consume a large amount of manpower. Some street lamps that can automatically clean mostly rely on electric drive, and the use of these electric components makes the use cost of the street lamps higher. Therefore, how to design an LED street lamp that can automatically clean the transparent lamp cover has become an urgent problem to be solved currently. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an energy-saving and environmentally friendly wide-angle LED street lamp that can automatically clean the lamp cover of the street lamp.

[0016] As a preferred technical solution of the present invention, a filter screen and filter cotton are sequentially installed in the water collecting cover from top to bottom.

[0017] The advantages of the present invention are as follows:

[0018] 1. The present invention uses rainwater as a cleaning medium, and through the cooperation of structures such as a water accumulation cylinder, a piston disk, and a hollow cleaning piece, realizes automatic water spraying and cleaning of the transparent lamp cover. In this process, no electricity and water resources are consumed, which conforms to the concept of energy conservation and environmental protection.

[0019] 2. When a certain amount of rainwater accumulates in the water accumulation cylinder in the present invention, the piston disk is pushed downward, driving the hollow cleaning piece to extend and cooperate with the transparent lamp cover. Under the action of external wind, the water accumulation cylinder rotates, and at the same time drives the hollow cleaning piece to rotate, completing the cleaning of the transparent lamp cover by the cleaning bristles. This process is timely and efficient, without manual intervention, and can significantly improve the lighting quality of the LED street lamp and extend its service life.

[0020] 3. Under windy and rainy weather conditions, the present invention can not only clean the transparent lamp cover by water spraying, but also realize jet cleaning of the transparent lamp cover through the cooperation of structures such as an air pump, an air guide channel, and an exhaust valve. The combination of water spraying cleaning and jet cleaning can significantly improve the cleaning effect, and at the same time accelerate the drying of rainwater on the surface of the transparent lamp cover, avoiding its adsorption of dust.

[0021] 4. Each component of the present invention has a compact structure and reasonable design, and is easy to install and maintain. The transparent lamp cover and the lamp housing are connected by threads, which is convenient for disassembly and replacement. Key components such as the water accumulation cylinder, the piston disk, and the hollow cleaning piece are made of corrosion-resistant and wear-resistant materials, ensuring the long-term stable operation of the street lamp.

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

[0048] Embodiment 1: Please refer to Figure 1-19 the structural schematic diagram. The present invention provides the following technical solutions:

[0049] Specifically, it refers to a wide-angle LED street lamp, 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 at the top and bottom of the fixing sleeve 2. An LED lamp head 4 is installed at the top inside the lamp housing 3 through a lamp holder. The bottom of the lamp housing 3 is threadedly connected with a transparent lamp cover 5. The transparent lamp cover 5 cooperates with the lamp housing 3 and is in a semi-circular ring shape longitudinally cut. Two circles of external thread sleeves are fixed at the top of the transparent lamp cover 5. Two circles of annular internal thread grooves matching the external thread sleeves are provided at the bottom of the lamp housing 3. The transparent lamp cover 5 and the lamp housing 3 are threadedly connected, which is convenient for replacement and maintenance while ensuring the connection sealing performance.

[0050] A water accumulation cylinder 6 is rotatably installed inside the fixing sleeve 2. The top of the water accumulation cylinder 6 extends to the top of the fixing sleeve 2 and is fixed with a water collection cover 7. The inner cavity of the water collection cover 7 is communicated with the inner cavity of the water accumulation cylinder 6. The first driving blade 8 and the second driving blade 9 are fixed on the outer surface of the water collection cover 7. The first driving blade 8 and the second driving blade 9 push the water accumulation cylinder 6 and the water collection cover 7 to rotate under the push of the external wind force. A filter screen 34 and a filter cotton 35 are installed in the water collection cover 7 from top to bottom in sequence. 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, ensure the cleanliness and hygiene of clean rainwater, and be more environmentally friendly.

[0051] A conical support cover 32 matching the water collection cover 7 is fixed at the top of the mounting bracket 1. Bearings 33 for supporting the water collection cover 7 are installed at the inner bottom and inner top of the conical support cover 32. A driving gap for cooperating with the second driving blade 9 is left between the inner surface of the conical support cover 32 and the outer surface of the water collection cover 7. It provides support for the water collection cover 7 and reduces the friction between structural components, ensuring that the water accumulation cylinder 6 and the water collection cover 7 can rotate under the action of wind force.

[0052] A piston disk 10 matching the water accumulation cylinder 6 is arranged inside the water accumulation cylinder 6. A support frame 11 is fixed at the bottom of the water accumulation cylinder 6. A spring 12 with its top end tightly abutted against the bottom of the piston disk 10 is installed at the center of the top of the support frame 11. A water blocking ring 13 concentric with the piston disk 10 is arranged inside the piston disk 10. A water outlet hole 14 penetrating through the piston disk 10 and communicating with the inner cavity of the piston disk 10 is opened at the inner bottom edge of the piston disk 10. An adjusting column 15 penetrates through the piston disk 10. The length of the adjusting column 15 is greater than the compressed length of the spring 12, ensuring that the water blocking ring 13 inside the piston disk 10 can be lifted before the spring 12 is completely compressed, and ensuring that rainwater can smoothly enter the hollow cleaning piece 18 through the water outlet hole 14. An installation frame 16 is fixed at the top of the adjusting column 15. The installation frame 16 is filled with a water-absorbing sponge 17. The water-absorbing sponge 17 is an antibacterial sponge. The weight of the water-absorbing sponge 17 when it is full of water plus the weight of the structure applied to the top of the spring 12 can offset the elongation amount of the spring 12. The outer surface of the bottom of the installation frame 16 is fixedly connected with the water blocking ring 13 through a connecting rod.

[0053] A number of hollow cleaning pieces 18 are fixedly connected to the bottom of the piston disk 10. The hollow cleaning pieces 18 not only have a small width, but also have a large enough gap between adjacent hollow cleaning pieces 18, and are close to the transparent lamp cover 5. Therefore, during cleaning, the influence on street lamp lighting is small. The inner cavity of the hollow cleaning piece 18 is communicated with the water outlet hole 14. A cleaning brush is installed on one surface of the hollow cleaning piece 18 facing the inner wall of the water collecting cylinder 6. A water spraying hole is opened on one surface of the hollow cleaning piece 18 facing the inner wall of the water collecting cylinder 6. A magnetic adsorption ring 19 matching with the hollow cleaning piece 18 is sleeved on the outer surface of the bottom of the lamp housing 3. A through hole 20 matching with the hollow cleaning piece 18 is opened on the support frame 11. The through hole 20 is also arc-shaped and concentric with the transparent lamp cover 5. The transparent lamp cover 5 is matched with the lamp housing 3 and is in a semi-circular ring shape longitudinally cut. Two circles of external thread sleeves are fixed on the top of the transparent lamp cover 5. Two circles of annular internal thread grooves matching with the external thread sleeves are opened at the bottom of the lamp housing 3. A section of the bottom of the water collecting cylinder 6 is in an arc shape that diffuses outward. The arc shape of a section of the bottom of the water collecting cylinder 6 is concentric with the lamp housing 3 and the transparent lamp cover 5.

[0054] When a certain amount of rainwater accumulates in the water collecting cylinder 6, it will squeeze the spring 12 at the bottom of the piston disk 10, causing the piston disk 10 to move downward, thereby driving the hollow cleaning piece 18 fixed to the bottom of the piston disk 10 to move downward. The hollow cleaning piece 18 extends to the bottom of the water collecting cylinder 6 through the through hole 20, and under the action of the arc-shaped through hole 20 and the arc at the bottom of the water collecting cylinder 6, the part extending out of the water collecting cylinder 6 will bend. Since the hollow cleaning piece 18 is made of elastic and magnetic metal, and with the magnetic adsorption of the magnetic adsorption ring 19, the hollow cleaning piece 18 will cooperate with the transparent lamp cover 5 at a certain arc. At this time, the cleaning brush on the hollow cleaning piece 18 contacts the transparent lamp cover 5. At the same time, since the water collecting cylinder 6 is fixedly connected to the support frame 11, under the action of external wind, when the water collecting cylinder 6 rotates, it will drive the support frame 11 to rotate, and the hollow cleaning piece 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 piece 18 to rotate. At this time, the cleaning brush can complete the cleaning of the transparent lamp cover 5 through the rotation of the hollow cleaning piece 18.

[0055] When enough water accumulates in the water collecting cylinder 6 (the state where the water absorption sponge 17 is full of water), the water collecting cylinder 6 moves downward to the limit (the weight of the water absorption sponge 17 full of water can offset the deformation amount of the spring 12, so that the set amount of the spring 12 is completely compressed). At this time, the adjusting column 15 is pushed up, so that the water outlet hole 14 sealed by the water blocking ring 13 leaks out. The filtered rainwater can enter the hollow cleaning piece 18 through the water outlet hole 14 and be sprayed out through the water spraying holes opened on the hollow cleaning piece 18 to wash the transparent lamp cover 5, and cooperate with the cleaning brush to brush while rotating, improving the cleaning effect on the transparent lamp cover 5, without consuming electricity and water resources, being energy-saving and environment-friendly.

[0056] When the water in the water accumulation cylinder 6 is consumed, the spring 12 is restricted by the water-absorbing sponge 17 filled with water. At this time, the piston disk 10 is not lifted. As the water accumulation cylinder 6 rotates, under the action of centrifugal force, the water in the water-absorbing sponge 17 is thrown out and enters the hollow cleaning piece 18 through the water outlet hole 14 for cleaning the transparent lamp cover 5. As the water in the water-absorbing sponge 17 is thrown out, the piston disk 10 is gradually lifted. At the same time, the hollow cleaning piece 18 begins to retract into the water accumulation cylinder 6, and the adjusting column 15 also gradually drops until the adjusting column 15 completely drops, and the water-blocking ring 13 contacts the inner bottom of the piston disk 10 to complete the sealing of the water outlet hole 14, and no longer injects rainwater into the hollow cleaning piece 18. Along with the entry of the rainwater filtered by the filter screen 34 and the filter cotton 35, the above process is carried out until the rainwater stops entering.

[0057] After the rainwater stops entering, as the rainwater in the water-absorbing sponge 17 is gradually discharged and evaporated, the piston disk 10 will rise to the top, and the hollow cleaning piece 18 will completely shrink into the water accumulation cylinder 6, while the bottom part of the hollow cleaning piece 18 is still located in the through hole 20, waiting for the next accumulation of water in the water accumulation cylinder 6 for cleaning work.

[0058] Embodiment 2: On the basis of the specific Embodiment 1, the difference in this embodiment is as follows:

[0059] As Figure 1-4 As shown in FIGS. 13-19, it further includes a dust-proof cover 21 and a driving gear 22. The driving gear 22 is sleeved on the outer circumferential surface of the top of the water accumulation cylinder 6. The dust-proof cover 21 is sleeved outside the fixed sleeve 2 and is fixedly connected to the mounting frame 1 by screws. There is enough space between the inner wall of the dust-proof cover 21 and the outer wall of the fixed sleeve 2 to form a transmission chamber 23. The dust-proof cover 21 is provided with a ventilation window with a dust-proof net to facilitate the entry of external air into the transmission chamber 23, which is convenient for the air pump 31 to inhale air during operation.

[0060] A reciprocating lead screw 24 is installed inside the transmission chamber 23. The top and bottom of the reciprocating lead screw 24 are respectively rotationally connected to the bottom of the mounting frame 1 and the top of the lamp housing 3. A driven gear 25 is fixedly sleeved on the reciprocating lead screw 24. The driven gear 25 penetrates the fixed sleeve 2 and meshes with the driving gear 22. A driving block 26 that is in transmission connection with the reciprocating lead screw 24 is sleeved on the reciprocating lead screw 24. A connecting plate is fixed on one surface of the driving block 26.

[0061] At the top of the lamp housing 3 and inside the transmission chamber 23, an annular air delivery groove 27 is provided. In the housing of the lamp housing 3, a number of air guiding channels 28 are provided. The air inlet end of the air guiding channel 28 communicates with the annular air delivery groove 27. The air outlet end of the air guiding 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 guiding channel 28. An arc-shaped air outlet pipe concentric with 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 role in guiding the flow, so that the cleaning air can blow and clean along the outer surface of the transparent lamp cover 5. The air outlet pipe is provided with auxiliary air outlet openings on the outer circular surface facing the transparent lamp cover 5. Multiple air outlet openings can blow and clean the transparent lamp cover 5 from multiple angles, so as to ensure the blowing and cleaning effect on the transparent lamp cover 5.

[0062] At the top of the lamp housing 3 and inside the transmission chamber 23, an annular concave sealing cover 30 that cooperates with the annular air delivery groove 27 is fixed by screws. A pump 31 (in this application, multiple groups of pumps 31 can be correspondingly set to improve the inflation efficiency) is fixed at the top of the annular concave sealing cover 30. The air outlet end of the pump 31 communicates with the inner cavity of the annular concave sealing cover 30 through an air delivery hose. The piston rod of the pump 31 is fixedly connected with the driving block 26 through a connecting plate.

[0063] Compared with the first embodiment, in this embodiment, under the conditions of whether there is rain or not, as long as there is wind blowing through the street lamp, the surface of the transparent lamp cover 5 can be cleaned. When there is no rain and there is wind, when the wind drives the water accumulation cylinder 6 to rotate through the first driving blade 8 and the second driving blade 9, since the driving gear 22 is fixedly installed on the water accumulation cylinder 6, the driving gear 22 also rotates accordingly. Thus, the reciprocating lead screw 24 is driven to rotate through the meshing of the driving gear 22 and the driven gear 25. The reciprocating lead screw 24 drives the driving block 26 thereon to reciprocate. Since the driving block 26 is connected with the piston rod of the pump 31 through a connecting plate, therefore, the piston rod of the pump 31 reciprocates, and the outside air is input into the air guiding channel 28 and the annular concave sealing cover 30 through the air delivery hose. When the pressure in the air guiding channel 28 and the annular concave sealing cover 30 reaches the threshold value set by the exhaust valve 29, the exhaust valve 29 opens, and the air in the air guiding channel 28 and the annular concave sealing cover 30 acts on the transparent lamp cover 5 through the arc-shaped air outlet pipe and the auxiliary air outlet openings, and the dust and dirt on it are cleaned by blowing, so as to ensure the cleanliness of the surface of the transparent lamp cover 5.

[0064] In the weather with wind and rain, this embodiment is carried out together with the water spraying cleaning of the first embodiment, so as to improve the cleaning effect on the surface of the transparent lamp cover 5. And the blowing and cleaning in this embodiment can accelerate the drying of the rainwater on the surface of the transparent lamp cover 5, avoid its adsorption of dust, and further improve the cleaning effect.

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