Description

Technical Field

[0001] The present application relates to the technical field of street lamps, and in particular to a combined LED street lamp. Background Art

[0002] A combined LED street light is a street light composed of multiple LED modules. It can produce different lighting effects and brightness by adjusting the operating modes of different LED modules to meet the road lighting needs in different scenarios. At the same time, the combined LED street light has the advantages of high efficiency, energy saving, environmental protection, and long life. It has now been widely used in the field of road lighting.

[0003] When the combined LED street lamp is turned on at night, the lampshade will produce strong light, and insects will hit the lampshade due to their phototaxis. After hitting the lampshade, the insects will inevitably leave insect spots or corpses on the outer surface of the lampshade. At the same time, under the long-term use of the street lamp, a large amount of dust and other impurities will adhere to the outer surface of the lampshade. After a large amount of accumulation of dirt adhered to the outer surface of the lampshade, the projection efficiency of the lampshade will be significantly reduced, resulting in a decrease in the lighting effect of the street lamp, which is obviously insufficient. Summary of the invention

[0004] In order to achieve automatic cleaning of the lampshade and improve the lighting effect of the street lamp, the present application provides a combined LED street lamp.

[0005] The combined LED street lamp provided in this application adopts the following technical solution: A combined LED street lamp comprises a lamp post, a lamp holder is arranged on the lamp post, a lamp cover is arranged on the lamp holder, a plurality of LED lamp group modules for lighting are arranged inside the lamp cover, a mounting frame is arranged on the lamp post, a cleaning assembly is arranged on the mounting frame, the cleaning assembly comprises a connecting plate slidably connected to the mounting frame, connecting columns are arranged at opposite ends of the connecting plate, a cleaning cylinder is connected and rotated together between the two connecting columns, the cleaning cylinder is made of elastic material, the cleaning cylinder abuts against the outer surface of the lamp cover, and a driving assembly is arranged on the lamp post to make the connecting plate reciprocate along the length direction of the mounting frame.

[0006] By adopting the above technical solution, the driving component drives the connecting plate to move back and forth along the length direction of the mounting frame, and in the process of the connecting plate moving, it drives the two connecting columns to move, and the movement of the connecting columns drives the cleaning barrel to move back and forth along the surface of the lampshade. At the same time, the cleaning barrel is made of elastic material to ensure that the cleaning barrel always fits the outer surface of the lampshade when moving. In the process of the reciprocating movement of the cleaning barrel, the cleaning barrel generates multiple scraping forces on the dirt adhered to the outer surface of the lampshade, and the dirt is finally cleaned out of the lampshade surface by the cleaning barrel. Such an arrangement realizes timely cleaning of the dirt on the lampshade surface, avoids the possibility of reduced light transmittance of the lampshade due to dirt accumulation, and thus improves the lighting effect of the street lamp.

[0007] Optionally, the driving assembly includes a reciprocating screw rotatably arranged on the mounting frame, the connecting plate is threadedly connected to the reciprocating screw, a driving shaft is rotatably connected to the lamp post, one end of the driving shaft extending out of the lamp post is fixedly connected to a wind wheel, and the driving shaft is coaxially and fixedly connected to the reciprocating screw.

[0008] By adopting the above technical solution, when the wind wheel rotates due to wind or rain, it drives the driving shaft to rotate, and the rotation of the driving shaft drives the reciprocating screw to rotate. During the rotation of the reciprocating screw, the connecting plate moves back and forth along the length direction of the reciprocating screw, and the movement of the connecting plate drives the cleaning cylinder to move, thereby finally achieving the cleaning effect of the cleaning component on the surface of the lampshade. The wind wheel drives the reciprocating screw to rotate, which realizes the utilization of natural resources, which is in line with the design concept of energy saving and environmental protection of street lamps.

[0009] Optionally, the driving assembly further comprises a water wheel coaxially fixedly connected to the driving shaft, the water wheel being rotatably connected to the inside of the lamp post, a rain storage box being arranged on the lamp post, a water outlet groove being arranged on the inner bottom surface of the rain storage box, a water blocking assembly for blocking the water outlet groove being arranged at the water outlet groove, a plurality of water outlet holes connected to the water outlet groove being arranged on the bottom surface of the rain storage box, and water outlet directions of the plurality of water outlet holes are all arranged toward the water wheel.

[0010] By adopting the above technical solution, when it rains, the rain storage box collects rainwater. When encountering windless and rainless weather, the water blocking component cancels the blockage of the water outlet groove, and the water inside the rain storage box passes through the water outlet groove and finally forms a water curtain to flow out from the water outlet hole. During the falling process, the water curtain hits the water wheel blades to rotate, and the rotation of the water wheel drives the reciprocating screw to rotate. When it is windy or rainy, the water blocking component automatically closes the water outlet groove to reduce the loss of water resources inside the rain storage box and ensure the timely supply of water resources inside the rain storage box. This arrangement extends the operating time of the cleaning component under any weather conditions, thereby improving the cleaning effect of the cleaning component on the surface of the lampshade, and at the same time further improves the utilization efficiency of natural resources.

[0011] Optionally, the water blocking assembly includes a water sealing plate slidably connected to the water outlet groove, fixed blocks are arranged on opposite end faces of the water sealing plate, fixed grooves slidably matched with the fixed blocks are provided on inner side walls opposite to the water outlet groove, a receiving groove is provided on the inner side wall of the fixed groove, a wedge block is slidably connected in the receiving groove, the inclined surface of the wedge block is arranged toward the fixed groove, a magnetic block is arranged at one end of the wedge block away from the fixed groove, an electromagnetic block for adsorbing the magnetic block is provided on the inner side wall of the receiving groove, and a first A spring, one end of the first spring is connected to the inner wall of the accommodating groove, and the other end is connected to the magnetic block. A gas spring is arranged in the fixed groove, and the top supporting end of the gas spring is connected to the fixed block. When the first spring is in a natural state, the bottom surface of the wedge block presses against the surface of the fixed block, the gas spring is compressed, and the outer surface of the water sealing plate is tightly fitted with the inner wall of the water outlet groove. A wind sensor and a rainfall sensor are arranged on the outer surface of the rain storage box, and the wind sensor and the rainfall sensor are both electrically connected to the electromagnetic block.

[0012] By adopting the above technical scheme, in natural weather, the first spring is in a natural state, the wedge block abuts against the fixed block and generates downward pressure on the fixed block, and the gas spring is in a compressed state. At this time, the water sealing plate blocks the water outlet groove. When the wind sensor and the rainfall sensor detect that there is no wind and no rain, the electromagnetic block is automatically energized, and the electromagnetic block attracts the magnetic block to move. The movement of the magnetic block drives the wedge block to separate from the fixed block, and the downward pressure on the fixed block disappears. The elastic force generated by the reset of the gas spring pushes the fixed block to move upward, and the upward movement of the fixed block drives the water sealing plate to move upward. At this time, a gap is generated between the water sealing plate and the water outlet groove, and the water in the rain storage box flows out of the water outlet groove. When there is wind and rain, the electromagnetic block is powered off, and the elastic force generated by the reset of the first spring pushes the wedge block to move toward the fixed block. The inclined surface on the wedge block pushes the fixed block to move downward in the fixed groove, and the downward movement of the fixed block drives the water sealing plate to re-block the water outlet groove. In this way, the switching between the water blocking and water discharge states of the water blocking component can be achieved by only turning on and off the power to the electromagnetic block, which further saves the loss of electric power resources and is energy-saving and environmentally friendly.

[0013] Optionally, a cavity is formed on the inner side walls opposite to each other of the mounting frame, a water outlet bag is provided at one end of the cavity, a water supply pipe connected to the water outlet bag is provided on the rain storage box, the water outlet bag is made of elastic material, two water outlet bags are connected with a water supply pipe, a corrugated pipe is connected on the water supply pipe, a connected water flow cavity is formed in the connecting plate, the connecting column and the cleaning barrel, the corrugated pipe is connected to the water flow cavity, a plurality of water outlets connected to the water flow cavity are formed on the surface of the cleaning barrel, and an extrusion component for extruding the water outlet bag is provided inside the cavity.

[0014] By adopting the above technical scheme, part of the water resources stored in the rain storage box is moved to the water outlet bag through the water supply pipe. When the extrusion component squeezes the water outlet bag, the water outlet bag is deformed by the extrusion force, and the water inside the water outlet bag is moved to the water flow cavity in the cleaning cylinder through the water supply pipe and the bellows, and finally sprayed to the outer surface of the lampshade from the water outlet. When the dirt on the outer surface of the lampshade is soaked by water, the adhesion of the dirt on the outer surface of the lampshade is reduced, making it easier to be cleaned by the cleaning cylinder. At the same time, the movement of the cleaning cylinder drives the water outlet to spray the outer surface of the lampshade in all directions, further improving the cleaning effect of the cleaning component.

[0015] Optionally, the extrusion assembly includes a rack plate arranged in the cavity, each of the rack plates is meshed with a gear, both ends of the connecting plate extend into the interior of the groove and are rotatably connected to a rotating rod, the gear is coaxially fixedly connected to the rotating rod, a cam is fixedly connected to the rotating rod, and when the raised end of the cam is facing the water outlet bag, the raised end of the cam squeezes the water outlet bag.

[0016] By adopting the above technical solution, during the process of the connecting plate moving along the length direction of the mounting frame, the connecting plate drives the rotating rod to move, and the movement of the rotating rod drives the gear to move along the length direction of the rack plate. At the same time, under the meshing of the gear and the rack plate, the gear rotates during the movement, and the rotation of the gear drives the cam to rotate around the rotating rod. When the raised end of the cam gradually approaches the water outlet bag, the water outlet bag is continuously squeezed by the cam, and the water in the water outlet bag flows into the bellows through the water supply pipe, and finally sprays from the water outlet to the outer surface of the lampshade.

[0017] Optionally, a return water bag is provided at one end of the cavity away from the water outlet bag, and the return water bag is made of elastic material. A drainage plate is provided inside the lamp post, and drainage grooves corresponding to the return water bags are opened on the drainage plate. The return water bag and the drainage grooves are connected through a first return water pipe. A second return water pipe is provided on the return water bag, and the water outlet end of the second return water pipe extends to the inside of the rain storage box. When the raised end of the cam faces the return water bag, the raised end of the cam squeezes the return water bag.

[0018] By adopting the above technical scheme, the water in the rain storage box falls on the drainage plate after passing through the water wheel, and moves to the return water bag through the first return water pipe under the drainage action of the drainage groove. When the raised end of the cam gradually approaches the return water bag, the return water bag is squeezed by the cam, and the water in the return water bag flows back to the inside of the rain storage box through the second return water pipe. The setting of the return water bag realizes the automatic water replenishment of the rain storage box, ensuring the stability of the water resources in the rain storage box. At the same time, the first return water pipe and the second return water pipe realize the recycling of the water resources in the rain storage box. In rainless weather, there is no need for external water resources to replenish the inside of the rain storage box, which further saves the loss of resources and ensures the stable operation of the cleaning component in windless and rainless weather.

[0019] Optionally, a sliding frame is provided at one end of the water return bag close to the drainage groove, and a float is slidably connected in the sliding frame. When the float moves to the water outlet end of the first water return pipe, the float closes the first water return pipe.

[0020] By adopting the above technical scheme, as the water level in the return water bag rises, the float moves upward along the sliding frame. When the float moves to the water outlet end of the first return water pipe, the float closes the first return water pipe. When the return water bag is squeezed, most of the water flows through the second return water pipe to the rain storage box, thereby avoiding the phenomenon of water in the return water bag flowing back to the drainage trough, thereby improving the recycling efficiency of water resources. When the water level in the return water bag drops, the float drops to open the water inlet channel of the first return water pipe, and the water in the drainage trough flows through the first return water pipe to the inside of the return water bag.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application sets a driving component and a cleaning component. The driving component drives the cleaning cylinder to move back and forth along the outer surface of the lampshade. The cleaning cylinder generates multiple scraping forces on the dirt when moving. The dirt is finally cleaned out of the lampshade surface by the cleaning cylinder. Such a setting realizes the timely cleaning of the dirt on the lampshade surface, avoids the possibility of the light transmittance of the lampshade decreasing due to the accumulation of dirt, and thus improves the lighting effect of the street lamp; 2. The present application provides a rain storage box and a water blocking component, and realizes the utilization of the rain storage box in different weather conditions by switching the water blocking and water releasing states of the water blocking component, thereby extending the operation time of the cleaning component under any weather conditions, thereby improving the cleaning effect of the cleaning component on the surface of the lampshade, and further improving the utilization efficiency of natural resources; 3. The present application arranges an extrusion component, a water outlet bag and a water return bag, and achieves the effects of water outlet from the water outlet bag and water return from the water return bag simultaneously through the extrusion component, thereby improving the cleaning effect of the outer surface of the lampshade and realizing the recycling of water resources.

[0031] The following is combined with Figure 1-8 This application is described in further detail.

[0032] The embodiment of the present application discloses a combined LED street lamp.

When the lighting environment required by the road surface changes, the control system automatically controls the LED lamp group modules to adjust the operating mode to achieve different lighting effects.

[0034] Reference Figure 1 and Figure 2The lamp post 01 is located above the lamp frame 02 and is fixedly installed with a mounting frame 1. The mounting frame 1 is provided with a cleaning assembly 2. The cleaning assembly 2 includes a connecting plate 21 slidably connected to the mounting frame 1. Sliding grooves 101 are provided on the opposite side walls of the mounting frame 1. The sliding grooves 101 extend along the length direction of the mounting frame 1. Both ends of the connecting plate 21 are slidably connected inside the sliding grooves 101. Connecting columns 22 are fixedly installed at both ends of the connecting plate 21 parallel to the length direction. The length between the two connecting columns 22 is greater than the width of the lampshade 03. The connecting columns 22 are vertically arranged. The bottom ends of the two connecting columns 22 are rotatably connected with a cleaning barrel 23. The outer surface of the cleaning barrel 23 is made of elastic material. In this embodiment, the connecting column 22 is made of polycarbonate material with high light transmittance, and the cleaning barrel 23 is made of transparent rubber material with high light transmittance. The center of the cleaning barrel 23 is flush with the lowermost end of the lampshade 03, and the cleaning barrel 23 abuts against the outer surface of the lampshade 03. A driving assembly 3 is provided on the lamp post 01.

[0035] Reference Figure 2 and Figure 3 The driving assembly 3 includes a reciprocating screw rod 31 rotatably connected to the inside of the mounting frame 1, the thread of the connecting plate 21 is connected to the reciprocating screw rod 31, and a driving shaft 32 is rotatably connected to the inside of the lamp post 01. The driving shaft 32 is coaxially and fixedly connected to the reciprocating screw rod 31. One end of the driving shaft 32 away from the reciprocating screw rod 31 extends out of the lamp post 01 and is fixedly connected to a wind wheel 33, which is rotatably connected to the outer surface of the lamp post 01.

[0036] When the wind wheel 33 rotates due to wind or rain, it drives the driving shaft 32 to rotate, and the driving shaft 32 drives the reciprocating screw rod 31 to rotate. During the rotation of the reciprocating screw rod 31, the connecting plate 21 reciprocates along the length direction of the reciprocating screw rod 31. During the movement of the connecting plate 21, it drives the two connecting columns 22 to move. The movement of the connecting columns 22 drives the cleaning barrel 23 to reciprocate along the surface of the lampshade 03. At the same time, the cleaning barrel 23 made of transparent rubber can ensure that the cleaning barrel 23 always fits the outer surface of the lampshade 03 and avoids the cleaning barrel 23 from being damaged. The influence of the cleaning cylinder 23 on the illumination. During the reciprocating movement of the cleaning cylinder 23, the cleaning cylinder 23 generates multiple scraping forces on the dirt adhered to the outer surface of the lampshade 03, and the dirt is finally cleaned out of the surface of the lampshade 03 by the cleaning cylinder 23. Such a setting can realize the timely cleaning of the dirt on the surface of the lampshade 03, avoid the possibility of the light transmittance of the lampshade 03 decreasing due to the accumulation of dirt, thereby improving the lighting effect of the street lamp. At the same time, the wind wheel 33 drives the reciprocating screw rod 31 to rotate to realize the utilization of natural resources, which is in line with the design concept of energy saving and environmental protection of street lamps.

[0037] Reference Figure 4 and Figure 5When there is no wind or rain, the wind wheel 33 cannot rotate effectively, so that the cleaning component 2 cannot effectively clean the outer surface of the lampshade 03. At this time, the dirt remaining on the outer surface of the lampshade 03 will still affect the lighting effect of the street lamp.

[0038] Reference Figure 4 and Figure 5 In order to solve the above problems, the driving component 3 also includes a water wheel 34 coaxially fixedly connected to the driving shaft 32, the water wheel 34 is rotatably connected to the inside of the lamp post 01, and the top of the lamp post 01 is fixedly connected to a rain storage box 4, the inner bottom surface of the rain storage box 4 is provided with a water outlet groove 5, and the water outlet groove 5 is provided with a water blocking component 6 for blocking the water outlet groove 5, the outer bottom surface of the rain storage box 4 extends to the inside of the lamp post 01 and is provided with a plurality of water outlet holes 41 connected with the water outlet groove 5, and the water outlet direction of the water outlet holes 41 is set toward the water wheel 34.

[0039] When it rains, the rain storage box 4 collects rainwater. When there is no wind or rain, the water blocking component 6 cancels the blockage of the water outlet 5. The water inside the rain storage box 4 passes through the water outlet 5 and finally forms a water curtain to flow out from the water outlet 41. During the falling process, the water curtain hits the blades of the water wheel 34 to rotate, and the rotation of the water wheel 34 drives the reciprocating screw 31 to rotate. When there is wind or rain, the water blocking component 6 automatically closes the water outlet 5 to reduce the loss of water resources inside the rain storage box 4 and ensure the timely supply of water resources inside the rain storage box 4. The cooperation of the water blocking component 6 and the water wheel 34 extends the operating time of the cleaning component 2 under any weather conditions, thereby improving the cleaning effect of the cleaning component 2 on the surface of the lampshade 03, and further improving the utilization efficiency of natural resources. Reference Figure 4 and Figure 5 The water blocking assembly 6 includes a water sealing plate 61 slidably connected to the water outlet groove 5. The water sealing plate 61 is door-shaped. Fixed blocks 62 are fixedly connected to the opposite end faces of the water sealing plate 61. Fixed grooves 51 that slide with the fixed blocks 62 are provided on the opposite inner walls of the water outlet groove 5. The fixed grooves 51 are vertically arranged. Under the sliding cooperation of the fixed blocks 62 and the fixed grooves 51, the water sealing plate 61 can only be lifted and lowered in the vertical direction along the accommodating grooves 52.

[0040] Reference Figure 4 and Figure 5Each fixed groove 51 has an inner side wall with a receiving groove 52, the length direction of the receiving groove 52 is perpendicular to the length direction of the fixed groove 51, each receiving groove 52 is slidably connected with a wedge block 63, the inclined surface of the wedge block 63 is arranged toward the fixed groove 51, the end of the wedge block 63 away from the fixed groove 51 is fixedly connected with a magnetic block 64, the magnetic block 64 is slidably connected inside the receiving groove 52, and the inner side wall of the receiving groove 52 away from the slide groove is fixedly connected with an electromagnetic block 65 for adsorbing the magnetic block 64. 2 is provided with a first spring 66, one end of the first spring 66 is connected to the inner bottom wall of the accommodating groove 52 near the electromagnetic block 65, and the other end is fixedly connected to the magnetic block 64. A gas spring 67 is fixedly connected to the inner side wall of the fixed groove 51, and the top support end of the gas spring 67 is fixedly connected to the bottom surface of the fixed block 62. When the first spring 66 is in a natural state, the bottom surface of the wedge block 63 presses against the surface of the fixed block 62, the gas spring 67 is compressed by the fixed block 62, and the outer surface of the water sealing plate 61 is tightly fitted with the inner side wall of the water outlet groove 5.

[0041] Reference Figure 4 and Figure 5 A wind sensor 42 and a rain sensor 43 for detecting climate conditions are fixedly mounted on the outer surface of the rain storage box 4. The wind sensor 42 and the rain sensor 43 are both electrically connected to the electromagnetic block 65 through a control system.

[0042] In natural weather, the first spring 66 is in a natural state, the wedge block 63 abuts against the fixed block 62 and generates downward pressure on the fixed block 62, and the gas spring 67 is in a compressed state. At this time, the water sealing plate 61 blocks the water outlet trough 5. When the wind sensor 42 and the rain sensor 43 detect that there is no wind or rain, the electromagnetic block 65 is automatically energized, and the electromagnetic block 65 attracts the magnetic block 64 to move. The movement of the magnetic block 64 drives the wedge block 63 to separate from the fixed block 62, and the downward pressure on the fixed block 62 disappears. The elastic force generated by the reset of the gas spring 67 pushes the fixed block 62 to move upward, and the fixed block 62 moves upward to drive the water sealing plate 61 When it moves upward, a gap is generated between the water sealing plate 61 and the water outlet trough 5, and the water in the rain storage box 4 flows out of the water outlet trough 5. When it is windy and rainy, the electromagnetic block 65 is powered off, and the elastic force generated by the reset of the first spring 66 pushes the wedge block 63 to move toward the fixed block 62. The inclined surface on the wedge block 63 pushes the fixed block 62 to move downward along the fixed groove 51. The downward movement of the fixed block 62 drives the water sealing plate 61 to re-block the water outlet trough 5. In this way, the water blocking component 6 can be switched between the water blocking and water discharge states by only turning the electromagnetic block 65 on and off, which further saves the loss of electric power resources and is energy-saving and environmentally friendly.

In the present embodiment, the water outlet bag 7 and the water return bag 8 are made of elastic rubber material. An inclined drainage plate 9 is fixedly installed inside the lamp post 01, and the inclined direction of the drainage plate 9 is set toward the mounting frame 1. A drainage groove 91 corresponding to the water return bag 8 is provided on the drainage plate 9. The water outlet end of the drainage groove 91 is connected to the inside of the water return bag 8 through the first water return pipe 81. Each water return bag 8 is connected with a second water return pipe 82, and the water outlet end of the second water return pipe 82 extends to the inside of the rain storage box 4.

[0044] Reference Figure 6 and Figure 7 The surface of the rain storage box 4 facing the mounting frame 1 is connected with a water pipe 44 corresponding to the water outlet bag 7. The water outlet end of the water pipe 44 is connected with the corresponding water outlet bag 7. The two water outlet bags 7 are commonly connected with a water delivery pipe 71. The water delivery pipe 71 is arranged perpendicular to the water outlet bag 7. Each water delivery pipe 71 is connected with a bellows 72. The water outlet end of the bellows 72 extends to the connecting plate 21 and is connected with the inside of the connecting plate 21. The connecting plate 21, the connecting column 22 and the cleaning cylinder 23 are all provided with a connected water passage cavity 10. The surface of the cleaning cylinder 23 is provided with a plurality of water outlets 1001 connected with the water passage cavity 10. The cavity 102 is provided with an extrusion component 11 for squeezing the water outlet bag 7 and the water return bag 8.

[0045] Reference Figure 6 and Figure 7 The extrusion assembly 11 includes a rack plate 111 fixedly installed inside the cavity 102, the rack plate 111 extends along the length direction of the mounting frame 1, and each rack plate 111 is meshed with a gear 112. Both ends of the connecting plate 21 extend into the cavity 102 and are rotatably connected to a rotating rod 113. The gear 112 and the rotating rod 113 are coaxially fixedly connected, and a cam 114 is fixedly connected to the outer surface of the rotating rod 113. When the cam 114 rotates until the length direction of the cam 114 is perpendicular to the length direction of the rotating rod 113, the opposite outer surfaces of the cam 114 respectively abut against the return water bag 8 and the outlet water bag 7.

[0046] Reference Figure 6 and Figure 7 , part of the water resources stored in the rain storage box 4 is moved to the water outlet bag 7 through the water delivery pipe 44, and at the same time, the water in the rain storage box 4 falls on the drainage plate 9 after passing through the water wheel 34, and moves to the return water bag 8 through the first return water pipe 81 under the drainage effect of the drainage groove 91; When the driving assembly 3 drives the connecting plate 21 to move along the length direction of the mounting frame 1, the connecting plate 21 drives the rotating rod 113 to move, and the movement of the rotating rod 113 drives the gear 112 to move along the length direction of the rack plate 111. At the same time, under the meshing of the gear 112 and the rack plate 111, the gear 112 rotates during the movement, and the rotation of the gear 112 drives the cam 114 to rotate around the rotating rod 113. When the cam 114 rotates, the raised end of the cam 114 gradually approaches the water outlet bag 7 or the water return bag 8, and the water outlet bag 7 and the water return bag 8 are continuously squeezed by the cam 114, wherein the water in the water outlet bag 7 flows into the bellows 72 through the water supply pipe 71, and is finally sprayed from the water outlet 1001 to the outside of the lampshade 03 When the dirt on the outer surface of the lampshade 03 is soaked by water, the adhesion of the dirt on the outer surface of the lampshade 03 is reduced, and it is easier to be cleaned by the cleaning tube 23. At the same time, the cleaning tube 23 moves to drive the water outlet 1001 to spray the outer surface of the lampshade 03 in all directions, further improving the cleaning effect of the cleaning component 2. When the return water bag 8 is squeezed by the cam 114, the water in the return water bag 8 flows back to the inside of the rain storage box 4 through the second return water pipe 82. The first return water pipe 81 and the second return water pipe 82 realize the recycling of water resources in the rain storage box 4. In rainless weather, there is no need to connect external water resources to replenish water in the rain storage box 4, which further saves resource loss and ensures the stable operation of the cleaning component 2 in windless and rainless weather. Reference Figure 7 and Figure 8 One end of the return water bag 8 close to the drainage groove 91 is fixedly connected to a sliding frame 12, the sliding frame 12 is vertically arranged, and a float 121 is slidably connected inside the sliding frame 12. As the water level in the return water bag 8 rises, the float 121 moves upward along the sliding frame 12. When the float 121 moves to the water outlet end of the first return water pipe 81, the float 121 closes the first return water pipe 81. When the return water bag 8 is squeezed, the water in the return water bag 8 moves to the rain storage box 4 through the second return water pipe 82. At this time, the water level in the return water bag 8 drops, and the float 121 drops to open the water inlet channel of the first return water pipe 81, and the water in the drainage groove 91 flows to the inside of the return water bag 8 through the first return water pipe 81.

[0047] The implementation principle of a combined LED street lamp in the embodiment of the present application is as follows: when the wind wheel 33 or the water wheel 34 rotates due to wind blowing or water curtain hitting, the wind wheel 33 or the water wheel 34 drives the driving shaft 32 to rotate, and the driving shaft 32 drives the reciprocating screw rod 31 to rotate. During the rotation of the reciprocating screw rod 31, the connecting plate 21 reciprocates along the length direction of the reciprocating screw rod 31, and during the movement of the connecting plate 21, the two connecting columns 22 are driven to move, and the movement of the connecting column 22 drives the cleaning cylinder 23 to reciprocate along the surface of the lampshade 03. At the same time, the cleaning barrel 23 made of transparent rubber can ensure that the cleaning barrel 23 always fits the outer surface of the lampshade 03 and avoids the influence of the cleaning barrel 23 on the lighting. In the process of reciprocating movement of the cleaning barrel 23, the cleaning barrel 23 generates multiple scraping forces on the dirt adhering to the outer surface of the lampshade 03, and the dirt is finally cleaned out of the surface of the lampshade 03 by the cleaning barrel 23. Such a setting realizes the timely cleaning of the dirt on the surface of the lampshade 03, avoids the possibility of the light transmittance of the lampshade 03 decreasing due to the accumulation of dirt, thereby improving the lighting effect of the street lamp.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
