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

[0003] Rapid economic development is often accompanied by serious environmental pollution. Many cities are prone to smog and dust weather in winter. Haze refers to fine particles and droplets suspended in the atmosphere, generally including smoke, dust, sulfates, nitrates, organic matter, etc. In order to improve the air quality, it is currently required that areas with more serious pollution install sprinkler heads on lamp poles to use spray mist to purify the air.

[0004] When adding sprinklers to street lamps to reduce dust, since sprinklers are generally exposed to the air, dust, sand, leaf fragments, insect corpses and other impurities in the air can easily enter the sprinkler heads over time. Dust raised by driving vehicles will continue to accumulate on the sprinkler heads. If these impurities enter the spray holes inside the sprinkler heads, the spray holes will be blocked, making it impossible for the sprinkler heads to spray water normally or spray water unevenly.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example:

[0043] See also Figure 1-Figure 10The present invention provides a technical solution: a street lamp lighting device with a spraying function, comprising 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, a spray head 8 is connected to the connecting pipe 10 through a thread, and spray holes are opened through the bottom wall of the spray head 8 at equal intervals, and a reciprocating cleaning mechanism is arranged in the connecting pipe 10, which can prevent the spray head 8 from being blocked by impurities, thereby ensuring 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, the cleaning needles 24 are driven by the needle plate 23 to reciprocate and clean the spray holes in the spray head 8 to prevent the spray holes of the spray head 8 from being clogged by dust, debris and scale.

[0045] In this embodiment, a water pipe 4 is provided in the connecting column 2, and a connecting frame 11 is fixedly installed. The connecting frame 11 is located above the water pipe 4, and the water pipe 4 is located above the connecting pipe 10. The water pipe 4 and the connecting pipe 10 are connected to each other. A piston plate 16 is movably installed inside the connecting frame 11, and a pressure plate 7 is fixedly installed on the top of several piston plates 16. A third extrusion spring is fixedly installed between the pressure plate 7 and the connecting column 2. A motor 5 is fixedly installed on the connecting column 2, and a cam column 6 is fixedly installed on the output shaft of the motor 5. The cam column 6 is in movably contact with the pressure plate 7. When the motor 5 rotates, it will drive the cam column 6 to rotate, and the cam column 6 will indirectly contact with the pressure plate 7 when it rotates. When the cam column 6 contacts the pressure plate 7, it will drive the pressure plate 7 to move downward, and the third extrusion spring will be compressed. At the same time, when the pressure 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, and the gas will enter 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 provided with a first branch pipe 13 and a second branch pipe 14. The second branch pipe 14 is provided with a third branch pipe 17. Part of the gas entering the second branch pipe 14 will enter the blowing nozzle 25 through the third branch pipe 17.

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

[0048] In this embodiment, the reciprocating cleaning mechanism also includes a fixed plate 28, a rotating plate 29 and a second connecting rod 30. The fixed plate 28 is arranged below the connecting frame 11. A second rotating block 32 is movably installed in the fixed 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 between the second connecting rod 30 and the rotating plate 29 deviates from the central axis of the rotating plate 29, so that the rotating plate 29 can drive the second connecting rod 30 to make up and down reciprocating motion when rotating, so as to drive the sliding block 21 to make up and down reciprocating motion in the connecting frame 11, thereby driving the needle plate 23 to make up and down reciprocating motion through the first connecting rod 21, so that the needle plate 23 and the cleaning needle 24 clean the spray hole in the spray head 8, and remove the dust, debris, scale, etc. attached to the spray hole.

[0050] In this embodiment, a tooth block portion is disposed on the first push column 31 , and the first push column 31 is meshedly connected with the gear portion 33 via the tooth block portion.

[0051] When the first push column 31 moves downward, it will drive the second rotating block 32 to rotate on one side of the fixed 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 make up and down reciprocating motion in the connecting tube 10 through the second connecting rod 30.

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

[0053] In this embodiment, the top 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, and the blowing nozzle 25 is located above the needle plate 23. The third branch pipe 17 is made of a retractable material, so 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 light pole 1, and each street light pole 1 is provided with a controller and an electronic water valve. Meanwhile, the controller is connected to the motor 5, and 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 sprinkler head 8 through the connecting pipe 10 for spraying. In this way, in haze weather and in dry weather, the sprinkler head 8 will spray water mist, which can reduce haze weather and dust in the air. At the same time, it can also water the plants under the street lights in dry weather, and can also cool the road surface and pedestrians.

[0056] Water holes are formed inside the sliding plate 21 and the needle plate 23 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 air blowing nozzle 25, and the connection between the needle plate 23 and the cleaning needle 24 are all fixedly connected.

[0057] When in use, the motor 5 works, and when the motor 5 works, the cam column 6 and the third extrusion spring drive the pressure plate 7 to make up and down reciprocating motion on the connecting column 2. When the pressure plate 7 moves downward, the gas in the connecting frame 11 enters the first branch pipe 13 and the second branch pipe 14 through the connecting main pipe 12 respectively. The gas entering the fixed frame 20 through the first branch pipe 13 prompts the first movable plate 26 to move downward in the fixed frame 20, squeezes the first extrusion spring 27, and drives the first push column 31 to move downward. When the first push column 31 moves downward, The second rotating block 32 is driven to rotate through the tooth block portion and the gear portion 33, and the rotating plate 29 is driven to rotate at the same time. When the rotating plate 29 rotates, it will drive the second connecting rod 30 to move, and 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, the sliding block 21 will be driven to make up and down reciprocating motion in the connecting tube 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 impurities in the spray hole in 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 tube 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 of the spray head through the spray hole, so as to prevent impurities from remaining on the cleaning needle 24, and at the same time, no impurities will remain inside the spray head 8, and at the same time, no water will be retained on the needle plate 23, so as to prevent water from remaining on the needle plate 23 and the cleaning needle 24.

[0059] See also Figure 11-Figure 12 The present invention provides a technical solution: 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, a second extrusion spring 35 and a push block 36 are fixedly installed at the bottom end of the second movable plate 34, the push block 36 is located below the fixed cylinder 15 and is not located inside the fixed cylinder 15, the second extrusion 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 arranged 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.

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 outer side of the push block 36, and a spiral groove matching the protrusion is provided on the outer side of the first rotating block 18. The push block 36 is slidably connected with 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, and a part of it 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, and the pushing block 36 is slidably connected with the spiral groove on the first rotating block 18 through the protrusion. In this way, when the pushing block 36 moves downward, the first rotating block 18 will rotate. When the first rotating block 18 rotates, it will drive the scraper 9 to rotate through the rotating column 19. When the scraper 9 rotates, it will scrape the bottom end surface of the spray head 8 clean to prevent dust and other impurities from remaining. At the same time, it can also prevent the bottom of the spray head 8 from freezing in winter, and the spray head 8 cannot perform the spraying function.

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

[0064] Working principle of this embodiment: When the motor 5 is working, it will drive the pressure plate 7 to make up and down reciprocating motion on the connecting column 2 through the cam column 6 and the third extrusion spring. When the pressure 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, squeeze the first extrusion spring 27, and at the same time drive the first push column 31 to move downward. When the first push column 31 moves downward, it will pass through The tooth block portion and the gear portion 33 drive the second rotating block 32 to rotate, 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, and 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, the sliding block 21 will be driven to reciprocate up and down in the connecting tube 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 impurities in the spray hole in the spray head 8 to prevent 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, and a part of the gas 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, the impurities cleaned by the cleaning needle 24 will be blown out of the spray head through the spray hole to prevent impurities from remaining on the cleaning needle 24. At the same time, no impurities will remain inside the spray head 8, and no water will be retained on the needle plate 23 to prevent water from remaining on the needle plate 23 and the cleaning needle 24.

[0066] At the same time, when the second movable plate 34 moves downward, the pushing block 36 will be driven to move downward, and the pushing block 36 is slidably connected with the spiral groove on the first rotating block 18 through the protrusion, so that when the pushing block 36 moves downward, the first rotating block 18 will be rotated, and when the first rotating block 18 rotates, the scraper 9 will be driven to rotate through the rotating column 19. When the scraper 9 rotates, the bottom end surface of the spray head 8 will be scraped clean to prevent dust and other impurities from remaining. At the same time, it can also prevent the bottom of the spray head 8 from freezing in winter, and the spray head 8 cannot perform the spraying function.
