Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and in particular to a street lamp with a self-cleaning lampshade. Background Art

[0002] Streetlights are typically used to provide nighttime illumination in roads and public spaces. They play a vital role in improving nighttime safety and facilitating the passage of pedestrians and vehicles. With technological advancements, LEDs are increasingly being used in streetlights, in addition to traditional high-pressure sodium and mercury lamps, due to their higher energy efficiency and longer lifespan.

[0003] A search revealed Chinese patent application number CN105020669B, which discloses a self-cleaning street lamp shade. The shade cleaning brush normally surrounds the base of the street lamp shade, preventing it from affecting the lighting. Driven by a brush rotating mechanism, it rotates against the outer wall of the shade, removing dust, insect spots, and insect stains adhering to the outer wall. While this self-cleaning street lamp shade has a reasonable structure and is easy to use, it can maintain a clean and beautiful appearance for a long time. However, this solution still has the following shortcomings in actual use:

[0004] In areas with poor air quality and high PM2.5 concentrations, street lamps exposed to such conditions for extended periods of time not only become contaminated with ordinary dust, but also, under the influence of nighttime dew, these tiny particles adhere and solidify on the lampshade's surface, forming a layer of dust crust that is difficult to remove. This phenomenon not only affects the street lamp's aesthetics but, more importantly, significantly reduces the brightness and diminishes the safety function it is supposed to provide. The cleaning method described above, which uses a light brush to sweep the surface, is limited in its effectiveness in removing this hard deposit formed by the combination of pollution and moisture, and often fails to fully restore the lampshade's light transmittance.

[0018] Beneficial effects of the present invention:

[0019] 1. This type of self-cleaning street lamp with a lampshade realizes dynamic optimization of energy by setting a wind cup and a drive component, and switching between the wind cup and the drive motor. When there is sufficient wind, it uses natural wind energy to drive the cleaning mechanism to reduce power consumption. When the wind is insufficient, it automatically switches to the drive motor to ensure the continuity of the cleaning operation. This design significantly improves energy utilization efficiency and reduces operating costs.

[0020] 2. This type of self-cleaning street lamp has a cleaning component and a humidifying component. The brush roller moves alternately in the linear guide groove and the corrugated guide groove, combined with the rotational motion, to achieve horizontal cleaning, vertical wave cleaning and large-angle water mist coverage of the bottom surface of the lampshade. The synergistic effect of mechanical brushing and atomizing spray can not only remove daily dust, but also break down stubborn attachments such as ash scabs, greatly improving the cleaning effect.

[0021] 3. This type of self-cleaning street lamp has a transmission structure. The brush roller contacts the tooth comb plate during the resetting process, automatically scraping off residual impurities on the bristles and sweeping out the dirt through the synchronous belt to avoid secondary contamination. At the same time, the linkage between the rotary spray of the duct and the piston pump during the entire cleaning process achieves uniform coverage and efficient utilization of water mist, reducing the frequency of manual maintenance.

[0022] 4. This type of self-cleaning street lamp has a lamp pole and lamp housing. The lifting frame is completely stored inside the lamp housing when not in operation, and the bottom surface is flush with the lamp housing. This not only protects the cleaning mechanism from external environmental erosion, but also keeps the appearance of the street lamp simple. The modular design integrates transmission, spraying, drive and other functions into one, achieving a balance between function and form, and is suitable for a variety of street lamp scenarios.

[0037] like Figures 1 to 9 As shown, a lampshade self-cleaning street lamp includes a lamp pole 1 and a wind cup 11 fixedly mounted on the top of the lamp pole 1. The top outer wall of the lamp pole 1 is provided with a lamp housing 2, the bottom surface of the lamp housing 2 is provided with a lampshade 21, the bottom surface of the lamp housing 2 is provided with a cleaning assembly, and the inner side of the lamp pole 1 is provided with a driving assembly adapted to the cleaning assembly.

[0038] The cleaning component includes a receiving groove 31 provided on the bottom surface of the lamp housing 2 at the side of the lampshade 21, a lifting frame 32 is slidably installed on the inner wall of the receiving groove 31, and two guide grooves 33 are symmetrically provided on the inner wall of the lifting frame 32. Two corrugated guide grooves 34 connected to the guide grooves 33 are provided on the inner wall of the lifting frame 32 above the two guide grooves 33. A shaft 36 is movably installed on the inner wall of the guide groove 33, and a brush roller 37 is fixedly mounted on the outer wall of the shaft 36. A tooth comb plate 310 adapted to the brush roller 37 is fixedly installed on the inner wall of the lifting frame 32. The inner top of the receiving groove 31 is fixed with a tooth comb plate 310 adapted to the brush roller 37. An electric push rod 311 is fixedly installed on the surface, and the telescopic end of the electric push rod 311 is fixedly connected to the top surface of the lifting frame 32. The inner wall of the lifting frame 32 is provided with a transmission structure corresponding to the shaft 36. The inner wall of the lifting frame 32 is located at the side positions of the guide grooves 33 and the corrugated guide grooves 34 on both sides. A transmission plate 35 is fixedly installed. Both ends of the shaft 36 are fixedly covered with a driven wheel 38 corresponding to the transmission plate 35. The inner wall of the lifting frame 32 is located at the end positions of the guide grooves 33 on both sides. Two magnetic pieces 39 are fixedly installed. The driven wheel 38 is made of metal material.

[0039] In the normal state of daily street lamps, the lifting frame 32 is located in the receiving groove 31, and the bottom surface of the lifting frame 32 can be flush with the bottom surface of the lamp housing 2 to avoid affecting the normal use of the lampshade 21. When it is necessary to clean the attachments on the lampshade 21, the electric push rod 311 can be opened and extended to drive the lifting frame 32 to slide along the receiving groove 31 and slide out of the receiving groove 31. At this time, the lifting frame 32 can be located outside the lampshade 21. In the initial state, the shaft rod 36 is located in the guide groove 33, and the shaft rod 36 can be driven to slide along the guide groove 33. In this state, the brush The bristles on the roller 37 just come into contact with the bottom surface of the lampshade 21, and then the dust on the bottom surface of the lampshade 21 can be cleaned when the shaft 36 moves along the guide groove 33, and with the cooperation of the driven wheel 38 and the transmission plate 35, the shaft 36 can rotate by the fit of the driven wheel 38 and the transmission plate 35 when it moves along the guide groove 33, which can drive the brush roller 37 to rotate, ensuring a better cleaning effect; and when the shaft 36 moves to the end of the guide groove 33 away from the lamp pole 1, the shaft 36 can move to the wave under the magnetic force of the upper magnetic piece 39. The shaft 36 can move in the corrugated guide groove 34 in the reverse direction under the action of the reciprocating screw 41. When the shaft 36 moves along the corrugated guide groove 34, it can also rotate under the action of the driven wheel 38 and the transmission plate 35. Under the action of the shape of the corrugated guide groove 34, the shaft 36 can move in the horizontal direction as well as in the vertical direction, thereby driving the fluctuating movement of the brush roller 37 to brush the bottom surface of the lampshade 21, ensuring that the dust scabs and other attachments that are difficult to clean on the lampshade 21 can be cleaned. When the shaft 36 moves to the end along the corrugated guide groove 34, the shaft 36 can be moved back to the guide groove 33 under the magnetic force of the lower magnetic sheet 39 so as to be used again; and when the shaft 36 moves from the corrugated guide groove 34 to the guide groove 33, the shaft 36 and the brush roller 37 can also rotate under the use of the driven wheel 38 and the transmission plate 35. When the brush roller 37 contacts the tooth comb plate 310 on the inner wall of the lifting frame 32, the tooth comb plate 310 can be used to scrape off impurities on the bristles on the surface of the brush roller 37.

[0040] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8As shown, the transmission structure includes two reciprocating screws 41 symmetrically rotatably mounted on the inner wall of the lifting frame 32, and the two reciprocating screws 41 are both threadedly fitted with guide blocks 42, the side surfaces of the guide blocks 42 fit into the inner wall of the lifting frame 32, and a telescopic link 43 is fixedly mounted on the bottom surface of the guide block 42, and the telescopic end of the telescopic link 43 is rotatably connected to the end of the shaft 36. The ends of the two reciprocating screws 41 and the inner wall of the lifting frame 32 are provided with four transmission wheels 44, and the outer walls of the four transmission wheels 44 are fitted with synchronous belts 45. The outer wall of the synchronous belt 45 is provided with bristles adapted to the tooth comb plate 310, and a transmission shaft 46 is provided through the side of the lifting frame 32, and one end of the transmission shaft 46 located on the inner side of the lifting frame 32 is fixedly mounted with a driving wheel 47 corresponding to the synchronous belt 45, and a clearance opening 48 adapted to the transmission shaft 46 is opened on the lamp housing 2 and the lamp pole 1, and the end of the transmission shaft 46 passes through the clearance opening 48 and is located on the inner side of the lamp pole 1;

[0041] When the transmission shaft 46 rotates, it can drive the driving wheel 47 to rotate, and then drive the four transmission wheels 44 to rotate through the synchronous belt 45. When the transmission wheel 44 rotates, it can drive the reciprocating screw 41 to rotate. Since the guide block 42 is screwed to the reciprocating screw 41, and the side surface is in contact with the inner wall of the lifting frame 32, it can drive the guide block 42 to slide back and forth. At the same time, since the shaft 36 is connected to the guide block 42 through the telescopic connecting rod 43, it can drive the shaft 36 to slide; when the synchronous belt 45 moves, the bristles on its surface can sweep off the attachments brushed off the tooth comb plate 310, preventing the attachments on the tooth comb plate 310 from re-entering the bristles on the brush roller 37.

[0042] like Figure 8 As shown, the drive assembly includes a driven bevel gear 51 fixedly mounted on the transmission shaft 46 at one end of the inner side of the lamp pole 1, a bracket 52 is slidably mounted on the inner wall of the lamp pole 1 through a slide groove and a slider, the bracket 52 is U-shaped, and the inner bottom surface and the inner top surface of the bracket 52 are rotatably mounted with a driving bevel gear 53 that meshes with the driven bevel gear 51, a driving motor 54 is fixedly mounted on the bottom surface of the bracket 52, a telescopic transmission rod 55 is fixedly mounted on the bottom end of the driving shaft of the wind cup 11, the bottom end of the telescopic transmission rod 55 and the output end of the driving motor 54 pass through the bracket 52 and are fixedly connected to the two driving bevel gears 53 respectively, an electric push rod 2 56 is fixedly mounted on the inner wall of the lamp pole 1, and the telescopic end of the electric push rod 2 56 is fixedly connected to the side of the bracket 52;

[0043] When the lifting frame 32 slides, it can drive the transmission shaft 46 to slide through the give way 48. At this time, the driven bevel gear 51 can slide on the inner side of the bracket 52. When the lampshade 21 is cleaned, the driving source can be selected according to the wind force in the environment monitored by the wind cup 11. If the wind force is strong, the electric push rod 2 56 can be opened and shortened, which can drive the bracket 52 to slide downward through the slide groove and the slider, so that the driving bevel gear 53 connected to the telescopic transmission rod 55 can mesh with the driven bevel gear 51, and the telescopic transmission rod 55 can be driven by the wind cup 11 to drive the transmission shaft 46 to rotate accordingly through the driving bevel gear 53 and the driven bevel gear 51. If the wind force is insufficient during cleaning, the electric push rod 2 56 can be extended so that the driving bevel gear 53 connected to the driving motor 54 on the bracket 52 can mesh with the driven bevel gear 51, thereby driving the transmission shaft 46. Through the flexible selection of the driving source, the power source for cleaning the lampshade 21 is ensured, while saving energy.

[0044] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 9 As shown, a humidifying assembly corresponding to the lampshade 21 is provided on the lifting frame 32, and the humidifying assembly includes two conduits 61 symmetrically mounted on the inner wall of the lifting frame 32. The outer walls of the two conduits 61 are provided with a plurality of atomizing nozzles 62 distributed in a linear array. The ends of the two conduits 61 pass through the side of the lifting frame 32 and are fixedly installed with a transmission gear 63. Two driving half gears 64 engaged with the transmission gear 63 are rotatably installed on the side of the lifting frame 32. The two driving half gears 64 are respectively fixedly connected to the two transmission wheels 44. The bottom surface of the lamp housing 2 is provided with a makeshift opening 8 corresponding to the transmission gear 63 and the driving half gear 64. A liquid storage box 65 is fixedly installed on the top surface of the lamp housing 2. Two sealing shells 66 are symmetrically fixedly installed on the end of the lifting frame 32 away from the lamp pole 1. The end of the lamp housing 2 Two openings 7 corresponding to the sealing shell 66 are provided. The lifting frame 32 is located on the side surface inside the sealing shell 66 and is rotatably installed with two reciprocating screws 67. The ends of the two reciprocating screws 67 are respectively fixedly connected to the ends of the two reciprocating screws 41. A piston plate 68 is slidably installed on the inner wall of the sealing shell 66, and the piston plate 68 is screwed to the reciprocating screw 67. A liquid extraction pipe 69 is provided between the top surface of the liquid storage box 65 and the sealing shell 66. A liquid outlet pipe 610 is provided between the bottom surface of the sealing shell 66 and the end of the conduit 61. The liquid outlet pipe 610 and the conduit 61 are connected through a rotary joint. One-way valves with opposite flow directions are installed inside the liquid extraction pipe 69 and the liquid outlet pipe 610. The end of the conduit 61 is provided with a torsion spring 611 with two ends respectively fixedly connected to the conduit 61 and the lifting frame 32.

[0045] During the entire cleaning process, the reciprocating screw 1 41 can synchronously drive the reciprocating screw 2 67 to rotate when it rotates. Since the piston plate 68 is screwed to the reciprocating screw 2 67 and is slidably connected to the inner wall of the sealing shell 66, the reciprocating screw 2 67 can drive the piston plate 68 to slide back and forth along the inner wall of the sealing shell 66 when it rotates. During the reciprocating sliding of the piston plate 68, under the action of the one-way valve in the liquid extraction pipe 69 and the liquid outlet pipe 610, the liquid in the liquid storage box 65 can be pumped into the sealing shell 66 through the liquid extraction pipe 69, and the liquid in the sealing shell 66 can be pushed into the conduit 61 through the liquid outlet pipe 610 and sprayed along the atomizing nozzle 62. In the process of the atomizing nozzle 62 spraying water mist, the driving wheel 44 can drive the driving half gear 64 to rotate when it rotates, and the driving half gear 64 is meshed with the transmission gear 63, and then when the driving half gear 64 is meshed with the transmission gear 63, The transmission gear 63 and the guide tube 61 are driven to rotate, and when the driving half gear 64 is separated from the teeth on the transmission gear 63, the transmission gear 63 and the guide tube 61 can be reversed under the action of the torsion spring 611, thereby realizing the reciprocating rotation of the guide tube 61, so that the atomizing nozzle 62 can spray water mist at a large angle, ensuring that the bottom surface of the lampshade 21 can be covered. When the shaft rod 36 slides in the guide groove 33, the water mist spraying can soften the attachments on the lampshade 21, and when the shaft rod 36 moves in the corrugated guide groove 34, the water mist spraying can ensure that the attachments are cleaned. After the lampshade 21 is cleaned as a whole, the electric push rod 2 56 can be reset to separate the driving bevel gear 53 from the driven bevel gear 51, and then the electric push rod 1 311 can be shortened to drive the lifting frame 32 to be reset to the receiving groove 31 to complete the storage, and the entire street lamp can be used normally.

[0046] The technical solution provided by the present invention is that when in use, under normal conditions of daily street lamps, the lifting frame 32 is located in the receiving groove 31, and the bottom surface of the lifting frame 32 can be flush with the bottom surface of the lamp housing 2 to avoid affecting the normal use of the lampshade 21. When it is necessary to clean the attachments on the lampshade 21, the electric push rod 311 can be opened and extended to drive the lifting frame 32 to slide along the receiving groove 31 and slide out of the receiving groove 31. At this time, the lifting frame 32 can be located on the outside of the lampshade 21. When the lifting frame 32 slides, it can drive the transmission shaft 46 to slide from the yielding port 48. At this time, the driven bevel gear 51 can slide on the inside of the bracket 52. When cleaning the lampshade 21, the driving source can be selected according to the wind force in the environment monitored by the wind cup 11. If the wind force is relatively strong, the lifting frame 32 can be opened and extended to drive the lifting frame 32 to slide along the receiving groove 31 and slide out of the receiving groove 31. When the wind speed is high, the second electric push rod 56 can be opened and shortened, and the bracket 52 can be driven to slide downward through the slide groove and the slider, so that the driving bevel gear 53 connected to the telescopic transmission rod 55 can mesh with the driven bevel gear 51, and the telescopic transmission rod 55 can be driven by the wind cup 11, thereby correspondingly driving the transmission shaft 46 through the driving bevel gear 53 and the driven bevel gear 51 to rotate. If the wind force is insufficient during cleaning, the second electric push rod 56 can be extended so that the driving bevel gear 53 connected to the driving motor 54 on the bracket 52 can mesh with the driven bevel gear 51, thereby driving the transmission shaft 46. By flexible selection of the driving source, the power source for cleaning the lampshade 21 is ensured, and energy is saved at the same time.

[0047] When the transmission shaft 46 rotates, it can drive the driving wheel 47 to rotate, and then drive the four transmission wheels 44 to rotate through the synchronous belt 45. When the transmission wheel 44 rotates, it can drive the reciprocating screw 41 to rotate. Since the guide block 42 is screwed to the reciprocating screw 41 and the side surface is in contact with the inner wall of the lifting frame 32, it can drive the guide block 42 to slide back and forth. At the same time, since the shaft 36 is connected to the guide block 42 through the telescopic connecting rod 43, it can drive the shaft 36 to slide. In the initial state, the shaft 36 is 6 is located in the guide groove 33, which can drive the shaft 36 to slide along the guide groove 33. In this state, the bristles on the brush roller 37 just contact the bottom surface of the lampshade 21, and then when the shaft 36 moves along the guide groove 33, the dust on the bottom surface of the lampshade 21 can be cleaned. In addition, under the cooperation of the driven wheel 38 and the transmission plate 35, when the shaft 36 moves along the guide groove 33, it can rotate through the contact of the driven wheel 38 and the transmission plate 35, which can drive the brush roller 37 to rotate, ensuring a better cleaning effect.

[0048] When the shaft 36 moves to the end of the guide groove 33 away from the lamp pole 1, the shaft 36 can move into the corrugated guide groove 34 under the magnetic force of the upper magnetic piece 39. At the same time, under the action of the reciprocating screw 41, the shaft 36 can move in the opposite direction along the corrugated guide groove 34. When the shaft 36 moves along the corrugated guide groove 34, it can also rotate under the action of the driven wheel 38 and the transmission plate 35. Under the action of the shape of the corrugated guide groove 34, the shaft 36 can move in the horizontal direction as well as in the vertical direction, thereby driving the fluctuating movement of the brush roller 37 to brush the bottom surface of the lamp shade 21, ensuring that the dust scabs and other attachments that are difficult to clean attached to the lamp shade 21 can be cleaned up. When the shaft 36 moves to the end along the corrugated guide groove 34, the shaft 36 can be moved back into the guide groove 33 under the magnetic force of the lower magnetic sheet 39 so as to be used again. When the shaft 36 moves from the corrugated guide groove 34 to the guide groove 33, the shaft 36 and the brush roller 37 can also rotate under the use of the driven wheel 38 and the transmission plate 35. When the brush roller 37 contacts the tooth comb plate 310 on the inner wall of the lifting frame 32, the tooth comb plate 310 can be used to scrape off the impurities on the bristles of the brush roller 37. At the same time, with the movement of the synchronous belt 45, the bristles on its surface can sweep off the attachments brushed off by the tooth comb plate 310, preventing the attachments on the tooth comb plate 310 from re-entering the bristles on the brush roller 37.

[0049] During the entire cleaning process, the reciprocating screw 1 41 can synchronously drive the reciprocating screw 2 67 to rotate when it rotates. Since the piston plate 68 is screwed to the reciprocating screw 2 67 and is slidably connected to the inner wall of the sealing shell 66, the reciprocating screw 2 67 can drive the piston plate 68 to slide back and forth along the inner wall of the sealing shell 66 when it rotates. During the reciprocating sliding of the piston plate 68, under the action of the one-way valve in the liquid extraction pipe 69 and the liquid outlet pipe 610, the liquid in the liquid storage box 65 can be pumped into the sealing shell 66 through the liquid extraction pipe 69, and the liquid in the sealing shell 66 can be pushed into the conduit 61 through the liquid outlet pipe 610 and sprayed along the atomizing nozzle 62. In the process of the atomizing nozzle 62 spraying water mist, the driving wheel 44 can drive the driving half gear 64 to rotate when it rotates, and the driving half gear 64 is meshed with the transmission gear 63, and then when the driving half gear 64 is meshed with the transmission gear 63, The transmission gear 63 and the guide tube 61 are driven to rotate, and when the driving half gear 64 is separated from the teeth on the transmission gear 63, the transmission gear 63 and the guide tube 61 can be reversed under the action of the torsion spring 611, thereby realizing the reciprocating rotation of the guide tube 61, so that the atomizing nozzle 62 can spray water mist at a large angle, ensuring that the bottom surface of the lampshade 21 can be covered. When the shaft rod 36 slides in the guide groove 33, the water mist spraying can soften the attachments on the lampshade 21, and when the shaft rod 36 moves in the corrugated guide groove 34, the water mist spraying can ensure that the attachments are cleaned. After the lampshade 21 is cleaned as a whole, the electric push rod 2 56 can be reset to separate the driving bevel gear 53 from the driven bevel gear 51, and then the electric push rod 1 311 can be shortened to drive the lifting frame 32 to be reset to the receiving groove 31 to complete the storage, and the entire street lamp can be used normally.
