Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and specifically to a street lamp lighting device with a spraying function. Background Art

[0002] At present, street lamps are installed on both sides or in the middle of roads to provide lighting. They are usually used at night or under low light conditions to improve the visibility and safety of roads. Street lamps can not only provide lighting for pedestrians and vehicles, but also improve the aesthetics of the city and the convenience of night activities.

[0003] The rapid economic development is often accompanied by serious environmental pollution. In many cities, haze weather and dust weather are likely to occur in winter. Haze refers to fine particulate matter and droplets suspended in the atmosphere, generally including soot, dust, sulfates, nitrates, organic matter, etc. At present, in order to improve the air quality, it is required to install spray heads on street lamp poles in areas with relatively serious pollution to purify the air by spraying.

[0004] When adding nozzles to street lamps for dust reduction, since the nozzles are generally exposed to the air, impurities such as dust, sand grains, leaf fragments, and insect corpses in the air are likely to enter the nozzles over time. The dust raised by vehicle driving will continuously accumulate on the nozzles. If these impurities enter the spray holes inside the nozzles, it will cause the spray holes to be blocked, making the nozzles unable to spray water normally or spray water unevenly.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment:

[0043] Please refer to Figures 1 - 10, the present invention provides a technical solution: a street lamp lighting device with a spraying function, including a street lamp pole 1, a connecting column 2 is fixedly installed on the side of the street lamp pole 1, and a street lamp 3 is fixedly connected through the connecting column 2. A connecting pipe 10 is fixedly installed in the connecting column 2. The connecting pipe 10 is threadedly connected with a spray head 8. The bottom wall of the spray head 8 is equidistantly penetrated with spray holes. A reciprocating cleaning mechanism is arranged in the connecting pipe 10. The reciprocating cleaning mechanism can prevent the spray head 8 from being blocked by impurities and ensure the normal spraying function of the spray head 8;

[0044] The reciprocating cleaning mechanism includes a needle plate 23 and cleaning needles 24. The cleaning needles 24 are fixedly installed at equal intervals below the needle plate 23. When the reciprocating cleaning mechanism works, it will drive the cleaning needles 24 through the needle plate 23 to reciprocally clean the spray holes in the spray head 8, preventing the spray holes of the spray head 8 from being blocked by dust, sundries, and water scale.

[0045] In this embodiment, a water pipe 4 is arranged in the connecting column 2, and a connecting frame 11 is fixedly installed. The connecting frame 11 is located above the water pipe 4. The water pipe 4 is located above the connecting pipe 10. The water pipe 4 and the connecting pipe 10 are interconnected. A piston plate 16 is movably installed inside the connecting frame 11. A pressing plate 7 is fixedly installed at the top of several piston plates 16. A third compression spring is fixedly installed between the pressing plate 7 and the connecting column 2. A motor 5 is fixedly installed on the connecting column 2. A cam column 6 is fixedly installed on the output shaft of the motor 5. The cam column 6 is in movable contact with the pressing plate 7. When the motor 5 rotates, it will drive the cam column 6 to rotate. When the cam column 6 rotates, it will intermittently contact the pressing plate 7. When the cam column 6 contacts the pressing plate 7, it will drive the pressing plate 7 to move downward, and the third compression spring will be compressed. At the same time, when the pressing plate 7 moves downward, it will drive the piston plate 16 to move downward in the connecting frame 11, and the gas in the connecting frame 11 will enter the connecting main pipe 12. The gas enters the first branch pipe 13 and the second branch pipe 14 respectively through the connecting main pipe 12.

[0046] A connecting main pipe 12 is fixedly installed through the side wall of the connecting frame 11. The end of the connecting main pipe 12 is divided into a first branch pipe 13 and a second branch pipe 14. The second branch pipe 14 is divided into a third branch pipe 17. A part of the gas entering the second branch pipe 14 will enter the blowing spray head 25 through the third branch pipe 17.

[0047] In this embodiment, a fixing frame 20 is fixedly installed on the connecting pipe 10. The first branch pipe 13 enters the connecting pipe 10 and extends deep into the fixing frame 20. A first movable plate 26 and a first compression spring 27 are respectively movably installed in the fixing frame 20. The first movable plate 26 is located below the first air pipe 13, and the first compression spring 27 is located below the first movable plate 26. A first pushing column 31 is fixedly installed at the bottom end of the first movable plate 26, and the first pushing column 31 penetrates through the inner wall of the bottom end of the fixing frame 20 and extends downward. After the gas in the first branch pipe 13 enters the fixing frame 20, it will press down the first movable plate 26, compress the first compression spring 27, and drive the first pushing column 31 to move downward. The first pushing column 31 is connected to the reciprocating cleaning mechanism.

[0048] In this embodiment, the reciprocating cleaning mechanism further includes a fixing plate 28, a rotating plate 29 and a second connecting rod 30. The fixing plate 28 is arranged below the connecting frame 11. A second rotating block 32 is movably installed in the fixing plate 28. A gear portion 33 is arranged on the outer side of the second rotating block 32, and the end is fixedly connected to the rotating plate 29. The rotating plate 29 is movably connected to the second connecting rod 30.

[0049] The connection position of the second connecting rod 30 and the rotating plate 29 deviates from the central axis of the rotating plate 29. In this way, when the rotating plate 29 rotates, it can drive the second connecting rod 30 to do up-and-down reciprocating motion, which is convenient for driving the sliding block 21 to do up-and-down reciprocating motion in the connecting frame 11. Thus, the needle plate 23 is driven to do up-and-down reciprocating motion through the first connecting rod 21, so that the needle plate 23 and the cleaning needles 24 clean the spray holes in the spray head 8, and remove the dust, sundries, water scale, etc. attached to the spray holes.

[0050] In this embodiment, a tooth block portion is arranged on the first pushing column 31, and the first pushing column 31 is meshed and connected to the gear portion 33 through the tooth block portion.

[0051] When the first pushing column 31 moves downward, it will drive the second rotating block 32 to rotate on one side of the fixing plate 28 through the tooth block portion and the gear portion 33. When the second rotating block 32 rotates, it will drive the rotating plate 29 to rotate. When the rotating plate 29 rotates, it will drive the sliding block 21 to do up-and-down reciprocating motion in the connecting pipe 10 through the second connecting rod 30.

[0052] In this embodiment, the ends of a plurality of second connecting rods 30 are fixedly connected to a sliding block 21 through a hinge seat. A first connecting rod 22 is fixedly installed at the bottom end of the sliding block 21, and the bottom end of the first connecting rod 22 is fixedly connected to the needle plate 23.

[0053] In this embodiment, the upper part of the sliding block 21 is connected to the third branch pipe 17, and the third branch pipe 17 passes through the sliding block 21 and is fixedly installed with a blowing nozzle 25. The blowing nozzle 25 is located above the needle plate 23. The third branch pipe 17 is made of a telescopic material. In this way, when the sliding block 21 moves downward, the third branch pipe 17 will also be fixedly connected to the sliding block 21 to prevent the third branch pipe 17 from being pulled off.

[0054] The water pipe 4 is connected to the municipal water pipe in the street lamp pole 1, and a controller and an electronic water valve are provided in each street lamp pole 1. At the same time, the controller is connected to the motor 5. The controller can control the operation of the motor 5 at any time. The controller, the electronic water valve and the motor 5 all adopt existing mature technologies.

[0055] The water in the water pipe 4 can enter the spray head 8 through the connecting pipe 10 for spraying. In this way, in haze weather and in dry weather, the spray head 8 will spray water mist. The water mist can reduce the haze and the dust in the air. At the same time, in dry weather, it can water the plants under the street lamps and can also cool the road surface and pedestrians.

[0056] Both the sliding plate 21 and the needle plate 23 are provided with water through holes inside to facilitate the water flow in the water pipe 4 to enter the connecting pipe 10 without being blocked. At the same time, the connection between the sliding block 21 and the blowing nozzle 25 and the connection between the needle plate 23 and the cleaning needle 24 are both fixedly connected.

[0057] During use, when the motor 5 operates, the motor 5 will drive the pressing plate 7 to move up and down on the connecting column 2 through the cam column 6 and the third compression spring. When the pressing plate 7 moves downward, the gas in the connecting frame 11 will enter the first branch pipe 13 and the second branch pipe 14 respectively through the connecting main pipe 12. The gas entering the fixed frame 20 through the first branch pipe 13 will cause the first movable plate 26 to move downward in the fixed frame 20, compress the first compression spring 27, and at the same time drive the first pushing column 31 to move downward. When the first pushing column 31 moves downward, it will drive the second rotating block 32 to rotate through the tooth block part and the gear part 33, and at the same time drive the rotating plate 29 to rotate. When the rotating plate 29 rotates, it will drive the second connecting rod 30 to move. The bottom end of the second connecting rod 30 is connected to the sliding block 21 through a hinge seat. In this way, when the rotating plate 29 rotates, it will drive the sliding block 21 to move up and down reciprocally in the connecting pipe 10 through the second connecting rod 30. At the same time, when the sliding block 21 moves, it will drive the needle plate 23 through the first connecting rod 22 so that the cleaning needle 24 can remove the impurities in the spray holes of the spray head 8 to prevent the spray head 8 from being blocked.

[0058] The gas entering the second branch pipe 14 will flow into the third branch pipe 17 through the fixed cylinder 15, and the gas entering the third branch pipe 17 will be blown out through the blowing nozzle 25. When the blowing nozzle 25 blows air, the impurities cleaned by the cleaning needle 24 will be blown out through the spray holes of the spray head, preventing impurities from remaining on the cleaning needle 24. At the same time, it can make the inside of the spray head 8 free of impurities, and can also prevent water from staying on the needle plate 23, preventing water from remaining between the needle plate 23 and the cleaning needle 24.

[0059] Please refer to Figures 11 - 12 In this embodiment, a fixed cylinder 15 is fixedly installed at the end of the second branch pipe 14. A second movable plate 34 is movably installed in the fixed cylinder 15. The bottom end of the second movable plate 34 is fixedly installed with a second compression spring 35 and a pushing block 36 respectively. The pushing block 36 is located below the fixed cylinder 15 and not inside the fixed cylinder 15. The second compression spring 35 is located inside the fixed cylinder 15 and is fixedly connected to the bottom end of the second movable plate 34. The third branch pipe 17 is located below the second movable plate 34. A limiting ring is provided inside the fixed cylinder 15. The second movable plate 34 is located above the limiting ring, and the connection port between the third branch pipe 17 and the fixed cylinder 15 is located below the limiting ring.

[0060] In this embodiment, a rotating column 19 is movably installed through the connecting column 2. A scraping plate 9 is fixedly installed at the bottom end of the rotating column 19. The scraping plate 9 is located below the spray head 8. A first rotating block 18 is fixedly installed at the top end of the rotating column 19.

[0061] In this embodiment, a protrusion is provided on the outside of the pushing block 36, and a spiral groove matching the protrusion is provided on the outside of the first rotating block 18. The pushing block 36 is slidably connected to the spiral groove on the first rotating block 18 through the protrusion.

[0062] The gas entering the second branch pipe 14 will cause the second movable plate 34 to move downward in the fixed cylinder 15. Part of the gas will enter the third branch pipe 17. At the same time, when the second movable plate 34 moves downward, it will drive the pushing block 36 to move downward. Since the pushing block 36 is slidably connected to the spiral groove on the first rotating block 18 through the protrusion, when the pushing block 36 moves downward, it will cause the first rotating block 18 to rotate. When the first rotating block 18 rotates, it will drive the scraping plate 9 to rotate through the rotating column 19. When the scraping plate 9 rotates, it will scrape the bottom end surface of the spray head 8 clean, preventing impurities such as dust from remaining. At the same time, in winter, it can also prevent the bottom end of the spray head 8 from freezing, so that the spray head 8 cannot perform the spraying function.

[0063] When the cam column 6 is separated from the pressing plate 7, under the action of the first compression spring 27, the second compression spring 35 and the third compression spring, the gas in the first branch pipe 13 and the second branch pipe 14 will flow back to the communication main pipe 12 to prepare for the next downward movement of the pressing plate 7.

[0064] Working principle of this embodiment: When the motor 5 operates, it drives the pressing plate 7 to move up and down on the connecting column 2 through the cam column 6 and the third compression spring. When the pressing plate 7 moves downward, the gas in the connecting frame 11 will enter the first branch pipe 13 and the second branch pipe 14 respectively through the connecting main pipe 12. The gas entering the fixed frame 20 through the first branch pipe 13 will cause the first movable plate 26 to move downward in the fixed frame 20, compress the first compression spring 27, and at the same time drive the first pushing column 31 to move downward. When the first pushing column 31 moves downward, it will drive the second rotating block 32 to rotate through the tooth block part and the gear part 33, and at the same time drive the rotating plate 29 to rotate. When the rotating plate 29 rotates, it will drive the second connecting rod 30 to move. The bottom end of the second connecting rod 30 is connected to the sliding block 21 through a hinge seat. In this way, when the rotating plate 29 rotates, it will drive the sliding block 21 to move up and down reciprocally in the connecting pipe 10. At the same time, when the sliding block 21 moves, it will drive the needle plate 23 through the first connecting rod 22 so that the cleaning needles 24 remove the impurities in the spray holes of the spray head 8, preventing the spray head 8 from being blocked.

[0065] The gas entering the second branch pipe 14 will cause the second movable plate 34 to move downward in the fixed cylinder 15. Part of it will enter the third branch pipe 17. The gas entering the third branch pipe 17 will be blown out through the blowing nozzle 25. When the blowing nozzle 25 blows air, it will blow out the impurities cleaned by the cleaning needles 24 through the spray holes of the spray head, preventing impurities from remaining on the cleaning needles 24. At the same time, it can make the inside of the spray head 8 free of impurities, and also can make the needle plate 23 free of water retention, preventing water from remaining on the needle plate 23 and the cleaning needles 24.

[0066] At the same time, when the second movable plate 34 moves downward, it will drive the pushing block 36 to move downward. The pushing block 36 is slidably connected to the spiral groove on the first rotating block 18 through a protrusion. In this way, when the pushing block 36 moves downward, it will cause the first rotating block 18 to rotate. When the first rotating block 18 rotates, it will drive the scraping plate 9 to rotate through the rotating column 19. When the scraping plate 9 rotates, it will scrape the bottom end surface of the spray head 8 clean, preventing impurities such as dust from remaining. At the same time, in winter, it can also prevent the bottom end of the spray head 8 from freezing, so that the spray head 8 cannot perform the spraying function.

[0067] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
