Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a multifunctional street light that uses activated carbon to filter air. Background Technology

[0002] Streetlights refer to the lighting fixtures used for road surface illumination in traffic lighting. They are the most common type of light, consisting of a lamp, wires, and a pole, and are widely used in various places requiring lighting to compensate for insufficient moonlight at night and provide safety for people traveling at night. Streetlights are mostly erected on both sides of the road to provide illumination for pedestrians and vehicles. Plants are also planted on both sides of the road to purify the exhaust fumes produced by vehicles. With social development, industrial, automotive, and domestic emissions have increased, and air pollution has become increasingly serious. Relying solely on plants to purify the air is inefficient, while activated carbon has good adsorption properties and can effectively remove a large number of harmful substances from the air. Therefore, a multifunctional streetlight using activated carbon to filter the air is proposed. Summary of the Invention

[0013] Optionally, a hollow collar is rotatably provided on the outside of the water storage tank, a spray head is fixedly provided on the side of the hollow collar away from the water storage tank, a water baffle is fixedly provided inside the hollow collar, a water pump is fixedly provided inside the water storage tank, a third water supply pipe is fixedly provided at the output end of the water pump, a plurality of fourth water supply pipes are connected to one side of the third water supply pipe, and the fourth water supply pipes are fixedly connected to the third water supply pipe, and the end of the fourth water supply pipe away from the third water supply pipe is an arc-shaped pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When rainwater falls into the first water pipe, it squeezes the turbine to rotate, causing the turbine to drive the cover to rotate on the filter plate. The cover drives the cleaning brush to rotate, which cleans the outer wall of the filter plate. The cleaning brush drives the scraper, which pushes away leaves and other debris that fall into the water collection tank, preventing them from clogging the rainwater and allowing it to pass through the filter plate into the water storage tank, thus improving the efficiency of rainwater collection.

[0016] 2. As the fan blades rotate, they draw air from inside the gas tank, causing it to be expelled through the outer shell. Since the air flowing out of the tank needs to be replenished by external air, this external air enters the water tank through the arc-shaped air inlet pipe. As the air passes through the inlet pipe, it undergoes a first filtration process, removing impurities such as lint. When the air enters the water tank and mixes with the water, it undergoes a second filtration, removing dust. The fan blades then draw the filtered air through the air inlet at the bottom of the protective shell, where it undergoes a third filtration process using activated carbon blocks, removing harmful substances such as formaldehyde and benzene. This multiple filtration process ensures cleaner air.

[0017] 3. Start the water pump. The water pump draws water from inside the water storage tank, allowing the water to enter the hollow collar through the third and fourth water supply pipes. Since the end of the fourth water supply pipe furthest from the third water supply pipe is an arc-shaped pipe, the water sprayed through the fourth water supply pipe squeezes the water-blocking plate, causing the water-blocking plate to drive the hollow collar to rotate around the water storage tank. The hollow collar drives the spray head to rotate, and while rotating, the spray head draws water from inside the hollow collar and sprays the water out. At this time, the water sprayed by the spray head irrigates the plants around the water storage tank, ensuring the plants' growth environment. In addition, the water mist sprayed by the spray head can cool the surrounding air while increasing the humidity in the air, further removing dust from the air. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Please see Figures 1 to 9 This invention provides a multifunctional street light that uses activated carbon to filter air, including a light pole 1 and light fixtures 2 fixedly installed on both sides of the light pole 1 to illuminate the road surface. The top of the light pole 1 is provided with a water collection mechanism 3 for collecting rainwater, and the bottom of the light pole 1 is provided with an air filtration mechanism 4 for filtering air. The bottom of the air filtration mechanism 4 is provided with an irrigation mechanism 5 for spraying the rainwater collected by the water collection mechanism 3, and the irrigation mechanism 5 performs secondary filtration on the air drawn in by the air filtration mechanism 4.

[0033] Furthermore, the water collection mechanism 3 collects rainwater on rainy days to improve the recycling of water resources. The collected rainwater is also convenient for secondary use in air purification. The air is filtered by the air filtration mechanism 4 to improve air quality. The irrigation mechanism 5 sprays the collected rainwater to irrigate the surrounding plants and increase the humidity of the surrounding air, thus removing dust from the air again.

[0034] The water collection mechanism 3 includes a first water supply pipe 31 fixedly installed at the top of the lamp post 1. A water collection trough 32 is fixedly installed at the end of the first water supply pipe 31 away from the lamp post 1, and the interior of the water collection trough 32 is inverted conical. The water collection trough 32 is connected to the first water supply pipe 31. A second water supply pipe 33 is fixedly installed on the outer side of the end of the first water supply pipe 31 near the lamp post 1, and the second water supply pipe 33 is connected to the first water supply pipe 31.

[0035] When rainwater falls into the water collection trough 32, the inverted cone shape of the water collection trough 32 makes it easier for water to flow into the interior of the first water supply pipe 31, which is conducive to the recycling of water resources.

[0036] A filter plate 34 is fixedly installed at the center of the water collection tank 32. A cover 35 is rotatably installed at the top of the filter plate 34. Multiple cleaning brushes 36 are fixedly installed at an eccentric position at one end of the cover 35 near the filter plate 34. The multiple cleaning brushes 36 are located on the outside of the filter plate 34 and are pressed and connected to the outer surface of the filter plate 34. A scraper 37 is fixedly installed at the bottom of the cleaning brush 36 and is pressed and connected to the inner wall of the water collection tank 32.

[0037] Furthermore, rainwater falls into the interior of the water collection trough 32 and flows along the inner wall of the water collection trough 32. The rainwater flows into the interior of the first water supply pipe 31 through the filter plate 34. The filter plate 34 filters out the impurities mixed in the rainwater, making it convenient for the reuse of rainwater and preventing impurities from entering the interior of the water storage tank 51.

[0038] A connecting rod 38 is fixedly installed at the center of the bottom end of the cover 35, and the end of the connecting rod 38 away from the cover 35 is located inside the first water supply pipe 31. A turbine 39 is fixedly installed at the end of the connecting rod 38 located inside the first water supply pipe 31.

[0039] Furthermore, when rainwater falls into the first water pipe 31, it compresses the turbine 39 to rotate, causing the turbine 39 to drive the cover 35 to rotate on the filter plate 34. The cover 35 drives the cleaning brush 36 to rotate, causing the cleaning brush 36 to clean the outer wall of the filter plate 34. The cleaning brush 36 drives the scraper 37, which pushes away leaves and other debris that fall into the water collection tank 32, preventing leaves and other debris from clogging the rainwater and causing it to enter the water storage tank 51 through the filter plate 34, thus affecting the efficiency of use.

[0040] The air filtration mechanism 4 includes an air storage tank 41 fixedly installed at the bottom of the lamp post 1, and the air filtration mechanism 4 also includes an exhaust assembly 42 fixedly installed on one side of the air storage tank 41.

[0041] The exhaust assembly 42 includes a housing 421 fixedly mounted on one side of the gas storage tank 41. A fan blade 422 is rotatably mounted inside the housing 421. A motor is fixedly mounted inside the housing 421, and the output end of the motor is fixedly connected to the fan blade 422. A sealing cover 423 is slidably mounted on one end of the housing 421 located outside the gas storage tank 41. A slide rod 424 is fixedly mounted on the side of the sealing cover 423 near the housing 421. A sliding groove is opened inside the housing 421, and the slide rod 424 slides inside the sliding groove. A telescopic spring 425 is fixedly mounted at the bottom end of the sliding groove, and the other end of the telescopic spring 425 is fixedly connected to the slide rod 424.

[0042] An arc-shaped protrusion 426 is fixedly provided at the center of one end of the sealing cover 423 near the outer shell 421. A rotating rod 427 is fixedly provided on one side of the fan blade 422 near the sealing cover 423. An L-shaped connecting rod 428 is fixedly provided on one side of the rotating rod 427. The L-shaped connecting rod 428 is L-shaped. A pulley 429 is rotatably provided at the end of the L-shaped connecting rod 428 away from the rotating rod 427. The pulley 429 is movably pressed and connected to the arc-shaped protrusion 426.

[0043] Furthermore, the motor inside the outer casing 421 is activated. The motor's output drives the fan blade 422 to rotate. When the fan blade 422 rotates, it drives the rotating rod 427 to rotate. The rotating rod 427 drives the pulley 429 to rotate through the L-shaped connecting rod 428. This causes the pulley 429 to press against the arc-shaped protrusion 426 and move it. The arc-shaped protrusion 426 then drives the sealing cover 423 to move. This causes the sealing cover 423 to drive the sliding rod 424 to move along the groove inside the outer casing 421, facilitating the flow of air through the outer casing 421. When the sliding rod 424 moves, it pulls the telescopic spring 425. When the pulley 429 is no longer pressing against the arc-shaped protrusion 426, the telescopic spring 425 drives the sliding rod 424 to move. The sliding rod 424 then drives the sealing cover 423 back to its initial position, causing the sealing cover 423 to press against the outer casing 421. This prevents external air from carrying dust into the air tank 41 when not in use, thus avoiding affecting the air filtration effect.

[0044] The air filtration mechanism 4 also includes an activated carbon component 43 fixedly installed at the bottom of the air storage tank 41, and the activated carbon component 43 penetrates the air storage tank 41. The activated carbon component 43 includes a protective shell 431, and an activated carbon block 432 is fixedly installed inside the protective shell 431. An air inlet 433 is opened at the bottom of the activated carbon block 432.

[0045] Furthermore, the filtered air is drawn into the interior of the protective shell 431 through the air inlet 433 at the bottom of the protective shell 431, and then undergoes a third filtration by the activated carbon block 432 to remove harmful substances such as formaldehyde and benzene from the air, making the air cleaner.

[0046] The irrigation mechanism 5 includes a water storage tank 51 fixedly installed at the bottom of the air storage tank 41. An arc-shaped air inlet pipe 44 is fixedly installed on the outside of the water storage tank 51 and is connected to the water storage tank 51. A filter screen 45 is fixedly installed at one end of the arc-shaped air inlet pipe 44 located on the outside of the water storage tank 51. The end of the second water supply pipe 33 away from the first water supply pipe 31 passes through the air storage tank 41 and the water storage tank 51 and is connected to the water storage tank 51.

[0047] Furthermore, as the fan blades 422 rotate, they draw air from inside the air tank 41, causing the air inside the air tank 41 to be discharged through the outer casing 421. Since the air inside the air tank 41 is flowing out, it needs to be replenished by external air. Therefore, external air flows into the water tank 51 through the arc-shaped air inlet pipe 44. When the air flowing into the water tank 51 passes through the arc-shaped air inlet pipe 44, it undergoes a first filtration through the filter screen 45, which removes impurities such as lint from the air, thereby increasing the efficiency of air filtration. When the air enters the water tank 51 and mixes with the water inside the water tank 51, the water performs a second filtration of dust from the air.

[0048] A hollow collar 52 is rotatably mounted on the outside of the water storage tank 51. A spray head 53 is fixedly mounted on the side of the hollow collar 52 away from the water storage tank 51. A water baffle 54 is fixedly mounted inside the hollow collar 52. A water pump 55 is fixedly mounted inside the water storage tank 51. A third water supply pipe 56 is fixedly mounted at the output end of the water pump 55. Multiple fourth water supply pipes 57 are connected to one side of the third water supply pipe 56, and the fourth water supply pipes 57 are fixedly connected to the third water supply pipe 56. The end of the fourth water supply pipe 57 away from the third water supply pipe 56 is an arc-shaped pipe.

[0049] Furthermore, the water pump 55 is activated, drawing water from the water storage tank 51. The water then flows through the third water pipe 56 and the fourth water pipe 57 into the hollow collar 52. Since the end of the fourth water pipe 57 furthest from the third water pipe 56 is an arc-shaped pipe, the water sprayed through the fourth water pipe 57 pushes the water-blocking plate 54 to move, causing the water-blocking plate 54 to drive the hollow collar 52 to rotate around the water storage tank 51. The hollow collar 52 drives the spray head 53 to rotate. While rotating, the spray head 53 draws water from the hollow collar 52 and sprays the water out. At this time, the water sprayed by the spray head 53 irrigates the plants around the water storage tank 51, ensuring the plant's growth environment. In addition, the water mist sprayed by the spray head 53 can cool the surrounding air while increasing the humidity in the air, thus further removing dust from the air.

[0050] Working principle: At night, lamp 2 is activated to illuminate the road surface, improving the safety of vehicles and pedestrians at night. When it rains, rainwater falls into the water collection trough 32 and flows along its inner wall. The rainwater then flows through filter plate 34 into the first water pipe 31. Filter plate 34 filters out impurities in the rainwater. As the rainwater falls into the first water pipe 31, it compresses turbine 39, causing turbine 39 to rotate and cover 35 to rotate on filter plate 34. Cover 35 then rotates cleaning brush 36, which cleans the outer wall of filter plate 34. Cleaning brush 36 drives scraper 37, which removes leaves and other debris that have fallen into the water collection trough 32. When rainwater from inside the first water pipe 31 flows through the first water pipe... The water flows into the second water supply pipe 33 through pipe 31, and then continues to flow into the water storage tank 51. The motor inside the outer casing 421 is activated, and its output drives the fan blade 422 to rotate. The rotation of the fan blade 422 drives the rotating rod 427 to rotate. The rotating rod 427 drives the pulley 429 to rotate via the L-shaped connecting rod 428, causing the pulley 429 to press against the arc-shaped protrusion 426. The arc-shaped protrusion 426 drives the sealing cover 423 to move, causing the sealing cover 423 to drive the sliding rod 424 to move along the groove inside the outer casing 421, facilitating air flow through the outer casing 421. As the sliding rod 424 moves, it pulls the telescopic spring 425. When the pulley 429 no longer presses against the arc-shaped protrusion 426, the telescopic spring 425 drives the sliding rod 424 to move along the groove inside the outer casing 421. 24. The slide bar 424 moves the sealing cover 423 back to its initial position, causing the sealing cover 423 to be pressed against the outer shell 421, preventing external air from entering the air tank 41 when not in use. As the fan blade 422 rotates, it draws air from inside the air tank 41, causing the air inside the air tank 41 to be discharged through the outer shell 421. Since the air inside the air tank 41 is flowing out, it needs to be replenished by external air. Therefore, external air flows into the water tank 51 through the arc-shaped air inlet pipe 44. When the air flowing into the water tank 51 passes through the arc-shaped air inlet pipe 44, it undergoes a first filtration through the filter screen 45, removing impurities such as lint from the air. When the air enters the water tank 51 and the air mixes with the water... When the water inside tank 51 is mixed, it filters the dust in the air a second time. The air is then drawn in through the air inlet 433 at the bottom of the protective shell 431 by the rotation of the fan blade 422. After passing through the activated carbon block 432, the air undergoes a third filtration, removing harmful substances such as formaldehyde and benzene, making the air cleaner. The air then flows into the gas storage tank 41 through the protective shell 431. The fan blade 422 then draws air from inside the gas storage tank 41, causing the filtered air to be discharged through the outer shell 421. On sunny days, the water pump 55 is activated, drawing water from the storage tank 51 and channeling it through the third water pipe 56 and the fourth water pipe 57 into the hollow collar 52.Because the end of the fourth water pipe 57 furthest from the third water pipe 56 is an arc-shaped pipe, the water sprayed through the fourth water pipe 57 forces the water-blocking plate 54 to move, causing the water-blocking plate 54 to drive the hollow collar 52 to rotate around the water storage tank 51. The hollow collar 52 drives the spray head 53 to rotate, and while rotating, the spray head 53 draws water from inside the hollow collar 52 and sprays the water out. At this time, the water sprayed by the spray head 53 irrigates the plants around the water storage tank 51, ensuring the plants' growing environment.
