Description

Technical Field

[0001] This invention relates to the field of street lighting technology, and more specifically, to an energy-saving device based on urban street lighting. Background Technology

[0002] Streetlights refer to lighting fixtures that provide illumination to roads, broadly encompassing the lighting fixtures within the road surface illumination range of traffic lighting. Streetlights are widely used in various locations requiring illumination. Solar streetlights, on the other hand, use crystalline silicon solar cells for power supply, maintenance-free valve-regulated sealed batteries for energy storage, and ultra-high brightness LED lights as the light source. They are controlled by an intelligent charge and discharge controller and are used to replace traditional public electric lighting, achieving significant energy savings.

[0003] Chinese invention patent publication number CN113790432A discloses an LED street light energy-saving device and method. The device includes an LED street light energy-saving unit, a power supply mechanism fixedly connected to the upper end of a mounting component, and an open box fixedly connected to the lower end of the power supply mechanism. A battery block is fixedly connected inside the open box, and the battery block is connected to the power supply mechanism via wires. The invention uses a light sensor to detect light intensity and transmits the signal to a controller, and a sound sensor to detect sound intensity and transmit the sound signal to the controller. When the sound intensity is less than a set value, all LEDs are turned off. When the sound intensity is greater than a set value and the light intensity is less than a set value, the controller controls the LEDs to turn on. When the sound intensity is greater than a set value and the light intensity is greater than a set value, the controller controls the LEDs to turn off. The LEDs are not turned on when there is no one around or when the light is strong, thus saving energy.

[0004] However, the above-mentioned device still has shortcomings. The wiping block in the device wipes the upper part of the solar panel through the cleaning mechanism, but during a period of wiping, a lot of impurities, dust and other dirt will accumulate on the wiping block. Not only will it fail to achieve the subsequent cleaning effect on the solar panel, but the dirt on the wiping block will also repeatedly come into contact with the solar panel, resulting in a situation where the more you wipe, the dirtier it gets.

[0005] Therefore, it is necessary to provide an energy-saving device based on urban streetlights to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving device based on urban streetlights to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving device based on urban street lighting, comprising a lamp post body and a fixing plate and a solar panel disposed on the upper end of the lamp post body.

[0009] As a further aspect of the present invention: the cleaning mechanism includes cleaning blocks that are symmetrically hinged to the inner wall of the cleaning tank on both sides, and a processing groove is provided at one end of the two cleaning blocks that are close to each other. A cleaning layer is provided on the surface of the processing groove, and the upper and lower ends of the cleaning blocks are connected to the inner wall of the cleaning tank through a first spring.

[0010] As a further aspect of the present invention: a water storage cavity is provided inside the cleaning block, and multiple water inlets and outlets communicating with the water storage cavity are respectively provided on the upper wall of the cleaning block and the outer wall of the treatment groove. A baffle is fixedly connected to the inner wall of the water storage cavity, and a through hole is provided in the middle of the baffle. A sealing component that can block the through hole is provided inside the water storage cavity.

[0011] As a further aspect of the present invention: the sealing assembly includes a second spring fixedly connected to the inner wall of the water storage chamber, the movable end of the second spring being fixedly connected to a sealing ball, the diameter of the sealing ball being larger than the diameter of the through hole, the outer wall of the sealing ball being fixedly connected to a traction rope, and the end of the traction rope away from the sealing ball moving through the outer wall of the cleaning block and fixedly connected to the inner wall of the cleaning tank.

[0012] As a further aspect of the present invention: the outer wall of the cleaning seat is provided with a plurality of discharge holes communicating with the cleaning tank, and the bottom of the cleaning tank is slidably connected with a plurality of tamping rods corresponding to the positions of the discharge holes.

[0016] Compared to existing technologies, the advantages of this invention are as follows: This solution uses a brush cluster to clean the surface of the solar panel, improving the illumination and energy-saving effect of streetlights. Furthermore, the brush cluster undergoes bending deformation due to pressure, resulting in a more thorough cleaning of the solar panel surface, especially effective at removing adhered dirt and dust. When the brush cluster enters the cleaning slot of the cleaning seat, the cleaning mechanism removes impurities and dust from the brush cluster, detaching them from the brush cluster. When the brush cluster is removed, the cleaning mechanism again cleans and wipes away any remaining impurities and dirt from its surface. This significantly reduces the accumulation of impurities and dirt on the brush cluster, ensuring a consistent cleaning effect and preventing further contamination of the solar panel upon subsequent contact. This allows the solar panel to operate effectively for a longer period, improving energy conversion and resulting in more significant energy savings. Furthermore, the cleaning mechanism can organize and gather the cleaning brush clusters, greatly preventing them from splitting during use. This ensures that the cleaning brush clusters can effectively clean the solar panels over a long period, improving the performance of the solar panels. Attached Figure Description

[0031] Example 1:

[0032] Please see Figure 1-2 and Figure 4-5An energy-saving device based on urban street lighting includes a lamp post body 1 and a fixing plate 2 and a solar panel 3 disposed on the upper end of the lamp post body 1. The upper and lower ends of the fixing plate 2 are fixedly connected to the solar panel 3 and the lamp post body 1, respectively. A transmission seat 4, a placement seat 5 and a cleaning seat 6 are fixedly connected to the side wall of the fixing plate 2, respectively. An installation rod 7 is provided above the placement seat 5. A transmission mechanism 8 that drives the installation rod 7 to move is provided inside the transmission seat 4. Multiple cleaning brush clusters 9 are fixedly installed at the bottom of the installation rod 7. A cleaning groove 10 is opened on the upper wall of the cleaning seat 6. Multiple cleaning mechanisms 11 that clean the cleaning brush clusters 9 are provided inside the cleaning groove 10. When using this device, after a period of use, the streetlight moves via the transmission mechanism 8, driving the mounting rod 7 and the cleaning brush cluster 9. The cleaning brush cluster 9 first moves out of the mounting base 5 and then contacts the surface of the solar panel 3. As the mounting rod 7 moves the cleaning brush cluster 9, it cleans the surface of the solar panel 3, preventing the accumulation of dust and dirt. This ensures the solar panel 3 receives sunlight effectively, greatly improving its performance and thus enhancing the streetlight's illumination and energy efficiency, meeting usage requirements. Furthermore, the cleaning brush cluster 9 bends under pressure, allowing for more thorough cleaning of the surface of the solar panel 3, especially adhering dirt and dust, resulting in a superior cleaning effect.

[0033] When the cleaning brush cluster 9 moves from the side of the solar panel 3 where it rests on the seat 5 to the side of the cleaning seat 6, it enters the cleaning groove 10 of the cleaning seat 6. There, with the assistance of the cleaning mechanism 11, the cleaning brush cluster 9 removes impurities and dust, detaching them from the brush cluster 9. When the mounting rod 7 moves the cleaning brush cluster 9 away to clean the surface of the solar panel 3 again, the cleaning mechanism 11 cleans and wipes away any remaining impurities and dirt. This ensures a good cleaning effect and greatly avoids the accumulation of impurities and dirt on the cleaning brush cluster 9. This not only guarantees the cleaning effect of the cleaning brush cluster 9 but also prevents the solar panel 3 from becoming even dirtier after subsequent contact with the brush cluster 9. This allows the solar panel 3 to work effectively for a long time, improving energy utilization and conversion, and resulting in more significant energy savings. Furthermore, the cleaning mechanism 11 can organize and gather the cleaning brush clusters 9, greatly preventing the cleaning brush clusters 9 from splitting too much during use. This ensures that the cleaning brush clusters 9 can effectively clean the solar panel 3 for a long time, thereby further improving the performance of the solar panel 3 and enhancing the energy-saving effect of the street light.

[0034] In this embodiment, preferably, please refer to [reference needed]. Figure 2-3 The transmission mechanism 8 includes a lead screw 801 rotatably connected to the left and right inner walls of the transmission base 4. A motor 802, which is driven and connected to the lead screw 801, is fixedly installed on the outer wall of the transmission base 4. A moving groove 803 is provided on the side wall of the transmission base 4. A connecting block 804 is slidably connected to the inner wall of the moving groove 803. One end of the connecting block 804 is fixedly connected to the mounting rod 7, and the other end of the connecting block 804 is threadedly connected to the lead screw 801. When the motor 802 is started, it drives the lead screw 801 to rotate. The lead screw 801 then drives the connecting block 804 to move along the moving groove 803. The connecting block 804 then drives the mounting rod 7 to move together, and the mounting rod 7 then drives the cleaning brush cluster 9 to move.

[0035] In this embodiment, preferably, please refer to [reference needed]. Figure 4-6 The cleaning mechanism 11 includes cleaning blocks 1101 that are symmetrically hinged to the inner wall of the cleaning tank 10. A processing groove 1102 is provided at one end of the two cleaning blocks 1101 that are close to each other. A cleaning layer is provided on the surface of the processing groove 1102. The upper and lower ends of the cleaning blocks 1101 are connected to the inner wall of the cleaning tank 10 through the first spring 1103. The processing groove 1102 is a cone shape with a radius smaller than that of the lower part, so that the cleaning brush cluster 9 can drive the two cleaning blocks 1101 to rotate downward after entering the cleaning tank 10, and will also cause the cleaning blocks 1101 to rotate upward when leaving the cleaning tank 10. When the cleaning brush cluster 9 enters the cleaning groove 10 of the cleaning seat 6, the cleaning block 1101 will rotate downward and open, stretching the upper first spring 1103 and compressing the lower first spring 1103. Then, the cleaning brush cluster 9 will pass through the cleaning blocks 1101 on both sides and enter the depth of the cleaning groove 10. As the cleaning brush cluster 9 moves downward from the cleaning blocks 1101 on both sides, the cleaning blocks 1101 can initially clean the impurities and dust on the cleaning brush cluster 9, causing them to detach from the cleaning brush cluster 9. When the cleaning brush cluster 9 is completely inside the cleaning groove 10, the cleaning brush cluster 9 will also be completely located between the two processing grooves 1102 on both sides. When the mounting rod 7 moves the cleaning brush cluster 9 away, the cleaning brush cluster 9 will gradually move away from the processing groove 1102. At this time, the surface of the cleaning brush cluster 9 can be cleaned and wiped again through the processing groove 1102, resulting in a good cleaning effect and greatly avoiding the accumulation of a lot of impurities and dirt on the cleaning brush cluster 9.

[0036] When the cleaning brush cluster 9 is removed from the processing grooves 1102 of the cleaning blocks 1101 on both sides, the processing grooves 1102 can also achieve the effect of tidying up and gathering the cleaning brush cluster 9, which greatly prevents the cleaning brush cluster 9 from splitting too much during use, so that the cleaning brush cluster 9 can ensure the long-term effective cleaning effect of the solar panel 3.

[0037] The upper wall of the placement seat 5 is provided with a placement groove 27, and the outer wall of the placement seat 5 is provided with an outlet 28 that communicates with the placement groove 27. When the cleaning brush cluster 9 is not in use, the cleaning brush cluster 9 can be moved to the placement groove 27 of the placement seat 5 for placement by the transmission mechanism 8. Rainwater that enters the placement groove 27 in rainy weather will flow out from the outlet 28.

[0038] Example 2:

[0039] Based on Example 1, please refer to Figure 7-8 and Figure 10 The cleaning block 1101 has a water storage cavity 12 inside. The upper wall of the cleaning block 1101 and the outer wall of the treatment groove 1102 have multiple water inlets 13 and outlets 14 that communicate with the water storage cavity 1103. A baffle 15 is fixedly connected to the inner wall of the water storage cavity 12. A through hole 16 is opened in the middle of the baffle 15. A sealing component that can block the through hole 16 is provided inside the water storage cavity 12. The sealing component includes a second spring 17 fixedly connected to the inner wall of the water storage cavity 12. A sealing ball 18 is fixedly connected to the movable end of the second spring 17. The diameter of the sealing ball 18 is larger than the diameter of the through hole 16. A traction rope 19 is fixedly connected to the outer wall of the sealing ball 18. The end of the traction rope 19 away from the sealing ball 18 moves through the outer wall of the cleaning block 1101 and is fixedly connected to the inner wall of the cleaning tank 10. During normal rainy days, rainwater enters the water storage chamber 12 through the inlet 13 on the cleaning block 1101 and is stored above the baffle 15. When the cleaning brush cluster 9 enters the cleaning trough 10, it causes the cleaning blocks 1101 on both sides to flip downwards. At the same time, the traction rope 19 connected to the inner wall of the cleaning block 1101 and the cleaning trough 10 is pulled. At this time, the traction rope 19 pulls the sealing ball 18 inside the cleaning block 1101. The sealing ball 18 is gradually disengaged from the through hole 16 by the pull of the traction rope 19. At this time, the through hole 16 is no longer blocked by the sealing ball 18. Figure 10As shown, at this time, some water in the water storage chamber 12 will enter the area below the baffle 15 through the through hole 16, and then flow out from the water outlet 14. The flowing water will fall onto the cleaning brush cluster 9, which can clean the cleaning brush cluster 9 and further improve the cleaning effect of the cleaning block 1101 and the treatment groove 1102 on the cleaning brush cluster 9. On the other hand, the water on the cleaning brush cluster 9 can make the cleaning effect better when cleaning the solar panel 3 later, and can better remove the residual dirt from the solar panel 3. Similarly, when the cleaning brush cluster 9 is removed from the cleaning tank 10, it will cause the cleaning block 1101 to rotate upward. Water will also flow out from the water storage chamber 12 of the cleaning block 1101 onto the cleaning brush cluster 9, and the cleaning blocks 1101 on both sides can squeeze the cleaning brush cluster 9, so that some sewage falls to the bottom of the cleaning tank 10. Finally, the water falling from the outlet 14 and the cleaning brush cluster 9 will be discharged from the drain hole 20 to the cleaning seat 6, which greatly improves the sustainable use of the cleaning brush cluster 9, thereby improving the working performance of the solar panel 3 and achieving good energy saving.

[0040] In this embodiment, preferably, please refer to [reference needed]. Figure 7 and Figure 9 A steering wheel 26 is fixedly installed on the outer wall of the cleaning block 1101. The traction rope 19 on the sealing ball 18 passes through the steering wheel 26 and is fixedly connected to the inner wall of the cleaning tank 10. The traction rope 19 rotates through the steering wheel 26, thereby better cooperating with the sealing ball 18. The setting of the steering wheel 26 can greatly avoid excessive wear on the traction rope 19 on the cleaning block 1101, which can greatly improve the service life of the traction rope 19 and also improve the subsequent effect on the sealing ball 18.

[0041] Example 3:

[0042] Based on Example 1, please refer to Figure 5-6 and Figure 11-12The outer wall of the cleaning seat 6 has multiple discharge holes 20 communicating with the cleaning tank 10. Multiple tamping rods 21 corresponding to the positions of the discharge holes 20 are slidably connected to the bottom of the cleaning tank 10. Connecting rods 22 are hinged to the upper outer wall of each tamping rod 21, and the upper end of each connecting rod 22 is hinged to the bottom of a corresponding cleaning block 1101. Support plates 23 fixed to the bottom wall of the cleaning tank 10 are provided on both the front and rear sides of the tamping rods 21. A sliding groove 24 is provided on the side of the support plate 23 closest to the tamping rod 21. A slider 25 is slidably connected to the inner wall of the sliding groove 24, and the end of the slider 25 away from the sliding groove 24 is fixedly connected to the outer wall of the tamping rod 21. During use, dust and impurities may accumulate in the discharge holes 20 communicating with the outside of the cleaning tank 10 and the cleaning seat 6, causing the discharge holes 20 to become blocked and preventing effective drainage of water from the cleaning tank 10. As the cleaning brush cluster 9 rotates downwards, causing the cleaning blocks 1101 on both sides to rotate, the cleaning block 1101 on the left side simultaneously drives the tamping rod 21 via the connecting rod 22 to slide along the slide groove 24 via the slider 25. At this time, the tamping rod 21 moves towards the discharge hole 20, eventually passing through the discharge hole 20. The tamping rod 21 effectively clears the discharge hole 20, greatly preventing blockage and thus avoiding affecting the subsequent cleaning effect and normal operation of the cleaning brush cluster 9. After the cleaning brush cluster 9 is removed from the cleaning groove 10, the cleaning block 1101 returns to its original position, and the tamping rod 21 returns to its initial position, no longer blocking the discharge hole 20.

[0043] Working Principle: When using this device, after the street light has been in use for a period of time, the starting motor 802 drives the lead screw 801 to rotate. The lead screw 801 then drives the connecting block 804 to move along the moving groove 803. The connecting block 804 then drives the mounting rod 7 to move together. The mounting rod 7 then drives the cleaning brush cluster 9 to move. The cleaning brush cluster 9 first moves out of the placement seat 5 and then contacts the surface of the solar panel 3. When the mounting rod 7 drives the cleaning brush cluster 9 to move, the cleaning brush cluster 9 will wipe and clean the surface of the solar panel 3, preventing the solar panel 3 from not receiving sunlight fully and thoroughly, thus greatly improving the performance of the solar panel 3. Furthermore, the cleaning brush cluster 9 will bend and deform due to the pressure, allowing it to clean the dirt on the surface of the solar panel 3 more thoroughly.

[0044] When the cleaning brush cluster 9 moves from the side of the solar panel 3 where the mounting base 5 is placed to the side of the cleaning base 6, the cleaning brush cluster 9 will enter the cleaning groove 10 of the cleaning base 6. At this time, the cleaning brush cluster 9 will cause the cleaning blocks 1101 on the left and right sides of the cleaning groove 10 to rotate downwards and open, stretching the first spring 1103 on the upper side and compressing the first spring 1103 on the lower side. Then the cleaning brush cluster 9 will pass through the cleaning blocks 1101 on both sides and enter the depth of the cleaning groove 10. As the cleaning brush cluster 9 moves downwards from the cleaning blocks 1101 on both sides, the cleaning blocks 1101 can initially clean the impurities and dust on the cleaning brush cluster 9, causing them to detach from the cleaning brush cluster 9. When the cleaning brush cluster 9 is completely inside the cleaning groove 10, the cleaning brush cluster 9 will also be completely located between the two processing grooves 1102 on both sides. When the mounting rod 7 moves the cleaning brush cluster 9 away to clean the surface of the solar panel 3 again, the cleaning brush cluster 9 will gradually move away from the processing groove 1102 of the cleaning block 1101. At this time, the processing groove 1102 can clean and wipe away the impurities and dirt on the surface of the cleaning brush cluster 9 again. This not only ensures that the cleaning brush cluster 9 can achieve the corresponding cleaning effect afterward, but also avoids that too much dirt remaining on the cleaning brush cluster 9 will make the solar panel 3 even dirtier after subsequent contact, resulting in a more significant energy-saving effect. Furthermore, when the cleaning brush cluster 9 moves away from the processing groove 1102 of the cleaning blocks 1101 on both sides, the processing groove 1102 can also achieve a tidying and binding effect on the cleaning brush cluster 9, greatly preventing the cleaning brush cluster 9 from splitting too much during use, thus ensuring that the cleaning brush cluster 9 can maintain a long-term and effective cleaning effect on the solar panel 3.

[0045] During normal rainy days, rainwater enters the water storage chamber 12 through the inlet 13 on the cleaning block 1101 and is stored above the baffle 15. When the cleaning brush cluster 9 enters the cleaning trough 10, it causes the cleaning blocks 1101 on both sides to flip downwards. At the same time, the traction rope 19 connected to the inner wall of the cleaning block 1101 and the cleaning trough 10 is pulled. At this time, the traction rope 19 pulls the sealing ball 18 inside the cleaning block 1101. The sealing ball 18 is gradually disengaged from the through hole 16 by the pull of the traction rope 19. At this time, the through hole 16 is no longer blocked by the sealing ball 18. Figure 10As shown, at this time, some water in the water storage chamber 12 will enter the area below the baffle 15 through the through hole 16, and then flow out from the water outlet 14. The flowing water will fall onto the cleaning brush cluster 9, which can clean the cleaning brush cluster 9. The water on the cleaning brush cluster 9 will also make the cleaning effect better when cleaning the solar panel 3 later. Similarly, when the cleaning brush cluster 9 is removed from the cleaning tank 10, it will cause the cleaning block 1101 to rotate upward. Water will also flow out from the water storage chamber 12 of the cleaning block 1101 onto the cleaning brush cluster 9. The cleaning blocks 1101 on both sides can squeeze the cleaning brush cluster 9, causing some sewage to fall to the bottom of the cleaning tank 10. Finally, the water falling from the water outlet 14 and the cleaning brush cluster 9 will be discharged from the discharge hole 20 to the cleaning seat 6.

[0046] During use, dust and impurities may accumulate in the discharge hole 20, which connects the cleaning tank 10 and the external cleaning seat 6, causing the discharge hole 20 to become blocked and preventing the water in the cleaning tank 10 from draining effectively. When the cleaning brush cluster 9 drives the cleaning blocks 1101 on both sides to rotate downwards, the cleaning block 1101 on the left side will simultaneously drive the tamping rod 21 via the connecting rod 22 to slide along the slide groove 24 via the slider 25. At this time, the tamping rod 21 will move towards the discharge hole 20, eventually passing through it and clearing the blockage. When the cleaning brush cluster 9 is removed from the cleaning tank 10, the cleaning block 1101 will return to its original position. Then, the connecting rod 22 will drive the tamping rod 21 to move inwards towards the interior of the cleaning tank 10, eventually returning the tamping rod 21 to its initial position and no longer blocking the discharge hole 20.
