[0001] The present invention relates to the technical field of street lamps, and particularly to a solar LED street lamp convenient for maintenance. Background Art

[0002] Street lamps are an important urban facility that can provide lighting at night, helping drivers identify road signs, traffic signals, and other vehicles at night or in low-light conditions, improving nighttime safety and reducing the occurrence of traffic accidents.

[0003] With the development of technology, the street lamps in cities have been replaced with LED street lamps, and the LED street lamps are powered by solar energy, which can save energy. At the same time, the LED street lamps are of a lifting type. When the LED street lamp fails, the LED street lamp can be lowered for maintenance. The lifting structure on the LED street lamp is exposed to the outside. Therefore, the inside of the LED street lamp is not sealed. If passers-by accidentally touch the exposed live parts, an electric shock accident may occur. Moreover, in rainy days, rainwater is also likely to enter the inside of the LED street lamp, causing the electrical components to short-circuit. Summary of the Invention

A solar panel is placed on the top of the placement plate. A storage battery is connected to the bottom of the mounting rod. A screw motor is installed inside the hollow column. The screw of the screw motor is threadedly connected to the sliding column to drive the sliding column to move downward. The sliding column drives the LED lamp and the solar panel to move downward, lowering the LED lamp and the solar panel. The LED lamp, the solar panel, and the screw motor are all electrically connected to the storage battery. A limiting mechanism for limiting the solar panel is provided on the placement plate. A fixing mechanism for fixing the LED lamp is provided on the mounting rod. A sealing mechanism for sealing the opening is provided on the hollow column.

[0006] In addition, it is particularly preferable that the limiting mechanism includes a guide rod, a limiting frame, a first spring, and a stabilizing component. Two guide rods are connected to both the left and right sides of the placement plate.

Slots are formed in the fixing blocks. The contact plates are located in the slots, which can stabilize the limiting frames and prevent the limiting frames from moving left and right. Two contact blocks are connected to the hollow column. First inclined surfaces are provided on the contact blocks. During the downward movement of the contact plates, the contact plates will contact the first inclined surfaces of the contact blocks. Under the action of the first inclined surfaces of the contact blocks, the two contact plates will move away from each other, and the contact plates will drive the two limiting frames to move away from each other, so that the limiting frames no longer limit the solar panel.

[0008] In addition, it is particularly preferable that the fixing mechanism includes a connecting block, an insertion block, a pulling plate, and a second spring. Two connecting blocks are connected to the LED lamp. Sockets are formed in the connecting blocks. Two insertion blocks are slidably connected to the mounting rod. The insertion blocks are inserted into the sockets to fix the LED lamp. A pulling plate is connected between the two insertion blocks. A second spring is connected between the pulling plate and the mounting rod.

[0009] In addition, it is particularly preferable that the sealing mechanism includes an arc-shaped plate, a contact strip, an arc-shaped rod, a third spring, a pushing block, and a fixing component. An arc-shaped groove is formed in the hollow column. An arc-shaped plate for sealing the opening is slidably connected in the arc-shaped groove. The arc-shaped plate contacts the front side of the sliding column. A contact strip is connected to the arc-shaped plate. An arc-shaped rod is connected in the arc-shaped groove. The arc-shaped rod is slidably connected to the arc-shaped plate. A third spring is connected between the hollow column and the arc-shaped plate. A pushing block is connected to the sliding column. A second inclined surface is provided at the bottom of the pushing block. The pushing block pushes the contact strip to move leftward through the second inclined surface, and the contact strip drives the arc-shaped plate to move leftward to open the arc-shaped plate.

[0010] In addition, it is particularly preferable that it further includes a clamping plate. A clamping groove is formed in the arc-shaped plate. A clamping plate is connected to the pushing block. The clamping plate is inserted into the clamping groove to clamp the arc-shaped plate.

[0011] In addition, it is particularly preferable that it further includes a mounting frame, a mounting plate, an electric push rod, and a wiping plate. A mounting frame is connected to the hollow column. A mounting plate is connected to the top of the mounting frame. An electric push rod is connected to the mounting plate. The front end of the telescopic rod of the electric push rod is connected to a wiping plate for wiping the solar panel. The bottom of the wiping plate contacts the top of the solar panel.

[0012] In addition, it is particularly preferred that it further includes a sliding rod, the sliding rod is slidably connected to the mounting plate, and the sliding rod is connected to the wiping plate.

[0013] The present invention has the following advantages: 1. The present invention can provide illumination through the LED lamp, improving the safety at night. The LED lamp and the solar panel can be driven to move downward by the lead screw, and the LED lamp and the solar panel can be lowered to a height convenient for maintenance by the staff, facilitating the maintenance of the LED lamp and the solar panel, and having higher safety.

[0015] 3. The top of the solar panel can be wiped by the wiping plate to clean the garbage on the top of the solar panel, preventing the garbage from blocking sunlight and reducing the light-receiving area of the solar panel, and ensuring the amount of solar radiation absorbed by the solar panel.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Such as Figures 1-11As shown in the figure, a solar LED street lamp convenient for maintenance includes a hollow column 1, a sliding column 2, a mounting rod 3, an LED lamp 5, a plug rod 6, a connecting plate 7, a placement plate 8, a solar panel 9, a storage battery 10, a screw motor 11, a limiting mechanism, a fixing mechanism and a sealing mechanism. An opening 101 is formed in the front side of the hollow column 1. A sliding column 2 is slidably connected inside the hollow column 1. A mounting rod 3 is connected to the front side of the sliding column 2. The mounting rod 3 extends out of the hollow column 1 through the opening 101. A circular groove 4 is formed in the front end of the mounting rod 3. A plug rod 6 is connected to the middle part of the rear side of the LED lamp 5. The plug rod 6 is inserted into the circular groove 4. Positioning grooves are formed in the upper and lower sides inside the circular groove 4. Positioning parts adapted to the positioning grooves are provided on the upper and lower sides of the plug rod 6. The positioning parts of the plug rod 6 are located in the positioning grooves, which can make the angle of the LED lamp 5 more accurate. The LED lamp 5 is obliquely arranged, which can make the light cover the areas that need lighting more, such as sidewalks, intersections, etc. A connecting plate 7 is connected to the top of the mounting rod 3. A placement plate 8 is connected to the top of the connecting plate 7. A solar panel 9 is placed on the top of the placement plate 8. Limiting parts are provided on the front and rear sides of the top of the placement plate 8. The limiting parts of the placement plate 8 can limit the solar panel 9 and prevent the solar panel 9 from sliding down. The solar panel 9 is obliquely arranged, which can make the rain flow down naturally and take away some dust and dirt. A storage battery 10 is connected to the bottom of the mounting rod 3. A screw motor 11 is installed inside the hollow column 1. The screw of the screw motor 11 is threadedly connected to the sliding column 2. The screw motor 11 is vertically arranged and can drive the sliding column 2 to move up and down. The LED lamp 5, the solar panel 9 and the screw motor 11 are all electrically connected to the storage battery 10. A limiting mechanism for limiting the solar panel 9 is provided on the placement plate 8. A fixing mechanism for fixing the LED lamp 5 is provided on the mounting rod 3. A sealing mechanism for sealing the opening 101 is provided on the hollow column 1.

[0031] As Figures 5-7 shown, the limiting mechanism includes a guide rod 12, a limiting frame 13, a first spring 14 and a stabilizing component. Guide rods 12 are symmetrically connected to the front and rear of the left and right sides of the placement plate 8. A limiting frame 13 is slidably connected to the two guide rods 12 on the left side together. A limiting frame 13 is also slidably connected to the two guide rods 12 on the right side together. First springs 14 are sleeved on the guide rods 12. The two ends of the first spring 14 are respectively connected to the placement plate 8 and the limiting frame 13. The first spring 14 is sleeved on the guide rod 12, which can prevent the first spring 14 from bending. A stabilizing component for stabilizing the limiting frame 13 is provided on the hollow column 1.

[0032] As Figures 5-7As shown, the stabilizing component includes a connecting frame 15, a contact plate 16, a fixing block 17 and a contact block 19. Connecting frames 15 are connected to the rear sides of the bottoms of the limiting frames 13. Contact plates 16 are connected to the bottoms of the connecting frames 15. Fixing blocks 17 are connected to the upper left and right sides of the front side of the hollow column 1. Slots 18 are formed in the front sides of the fixing blocks 17. The contact plates 16 are located in the slots 18. Contact blocks 19 are connected to the lower left and right sides of the front side of the hollow column 1. First inclined surfaces 20 are provided on the mutually remote sides of the two contact blocks 19. The contact plates 16 will contact the first inclined surfaces 20 of the contact blocks 19 during the downward movement.

[0033] As Figure 8 and Figure 9 As shown, the fixing mechanism includes a connecting block 21, an inserting block 23, a pulling plate 24 and a second spring 25. Connecting blocks 21 are connected to the upper left and right sides of the rear side of the LED lamp 5. Sockets 22 are formed in the middles of the connecting blocks 21. Inserting blocks 23 are slidably connected to the upper left and right sides of the front part of the mounting rod 3. The inserting blocks 23 are located in the sockets 22. A pulling plate 24 is connected between the two inserting blocks 23. Two second springs 25 are connected between the bottom of the pulling plate 24 and the mounting rod 3.

[0034] Install the hollow column 1 at the designated position. The LED lamp 5 can provide illumination to improve the safety at night. When the LED lamp 5 or the solar panel 9 fails and needs to be repaired, control the lead screw motor 11 to drive the sliding column 2 to move downward. The sliding column 2 drives the mounting rod 3 to move downward. The mounting rod 3 drives the LED lamp 5 and the solar panel 9 to move downward, lowering the LED lamp 5 and the solar panel 9 to a height convenient for the staff to repair, facilitating the repair of the LED lamp 5 and the solar panel 9, and with higher safety. The downward movement of the mounting rod 3 can also drive the limit frame 13 to move downward. The limit frame 13 drives the connecting frame 15 and the contact plate 16 to move downward. The contact plate 16 moves out of the slot 18. Subsequently, the contact plate 16 continues to move downward. During the downward movement of the contact plate 16, it will contact the first inclined surface 20 of the contact block 19. Under the action of the first inclined surface 20 of the contact block 19, the two contact plates 16 will move away from each other. The contact plate 16 drives the two connecting frames 15 to move away from each other. The connecting frame 15 drives the two limit frames 13 to move away from each other, automatically releasing the limit on the solar panel 9, making the operation more convenient. The first spring 14 is compressed, and the staff can repair or replace the solar panel 9. After the repair is completed, place the solar panel 9 on the placement plate 8. The limiting part of the placement plate 8 can limit the solar panel 9 to prevent it from sliding down. The staff pulls up the pull plate 24, stretching the second spring 25. The pull plate 24 drives the plug 23 to move upward. The plug 23 moves out of the socket 22, releasing the LED lamp 5. The staff can then repair or replace the LED lamp 5. After the repair is completed, insert the insertion rod 6 into the circular groove 4. The positioning part of the insertion rod 6 will insert into the positioning groove to ensure the accuracy of the angle of the LED lamp 5. Then release the pull plate 24. Under the action of the second spring 25, the pull plate 24 moves downward. The pull plate 24 drives the plug 23 to move downward. The plug 23 inserts into the socket 22 to fix the LED lamp 5. Control the lead screw motor 11 to drive the sliding column 2 to move upward. The sliding column 2 drives the LED lamp 5 and the solar panel 9 to move upward, raising the LED lamp 5 and the solar panel 9. The upward movement of the mounting rod 3 can also drive the contact plate 16 to move upward. The contact plate 16 disengages from the first inclined surface 20 of the contact block 19. Under the action of the first spring 14, the two limit frames 13 move closer to each other, limiting the solar panel 9 to prevent it from moving, and automatically limiting the solar panel 9, making the operation more convenient. Subsequently, the contact plate 16 will insert into the slot 18, which can stabilize the limit frame 13 and prevent the limit frame 13 from moving left and right. The sunlight shines on the solar panel 9. The solar panel 9 converts light energy into electrical energy, and the electrical energy is stored in the storage battery 10. The storage battery 10 supplies power to the LED lamp 5 and the lead screw motor 11, saving resources.

[0035] As Figure 10 and Figure 11As shown in the figure, the sealing mechanism includes an arc-shaped plate 27, a contact strip 271, an arc-shaped rod 28, a third spring 29, a push block 30 and a fixing component. An arc-shaped groove 26 is formed on the hollow column 1. An arc-shaped plate 27 is slidably connected in the arc-shaped groove 26. The arc-shaped plate 27 contacts the front side of the sliding column 2. The right part of the front side of the arc-shaped plate 27 is connected with a contact strip 271. Four arc-shaped rods 28 are evenly spaced and connected in the arc-shaped groove 26. The arc-shaped rods 28 are slidably connected with the arc-shaped plate 27. The four arc-shaped rods 28 jointly guide and support the arc-shaped plate 27, which can prevent the arc-shaped plate 27 from tilting. Third springs 29 are sleeved on the arc-shaped rods 28. The two ends of the third spring 29 are respectively connected with the hollow column 1 and the arc-shaped plate 27. The third spring 29 is sleeved on the arc-shaped rod 28, which can prevent the third spring 29 from bending. The front side of the sliding column 2 is connected with a push block 30. A second inclined surface 31 is provided at the bottom of the push block 30. The contact strip 271 is vertically arranged. After the push block 30 pushes the contact strip 271 to move leftward, the push block 30 can always push the contact strip 271, keeping the arc-shaped plate 27 in an open state all the time.

[0036] As Figure 10 and Figure 11 shown in the figure, it further includes a clamping plate 33. A clamping groove 32 is formed in the upper part of the front side of the arc-shaped plate 27. The left part of the front side of the push block 30 is connected with a clamping plate 33. The clamping plate 33 is located in the clamping groove 32.

[0037] The arc-shaped plate 27 seals the opening 101, preventing rainwater from entering the hollow column 1 and causing short circuits of electrical components, and can also prevent passers-by from accidentally touching the electrical components in the hollow column 1, thus avoiding electric shock accidents. The clamping plate 33 is inserted into the clamping groove 32, which can clamp the arc-shaped plate 27 and prevent passers-by from opening the arc-shaped plate 27 at will. When the sliding column 2 moves downward, it will drive the push block 30 and the clamping plate 33 to move downward. The clamping plate 33 moves out of the clamping groove 32, releasing the arc-shaped plate 27. Then the second inclined surface 31 of the push block 30 will contact the contact strip 271. The push block 30 pushes the contact strip 271 to move leftward through the second inclined surface 31. The contact strip 271 drives the arc-shaped plate 27 to move leftward, opening the arc-shaped plate 27 and preventing the installation rod 3 from colliding with the arc-shaped plate 27. The third spring 29 is compressed. When the sliding column 2 moves upward, it will drive the push block 30 and the clamping plate 33 to move upward. After the second inclined surface 31 of the push block 30 separates from the contact strip 271, under the action of the third spring 29, the arc-shaped plate 27 moves rightward to close the arc-shaped plate 27. Then the clamping plate 33 will be inserted into the clamping groove 32 to re-clamp the arc-shaped plate 27.

[0038] As Figure 1 and Figure 12As shown in the figure, it further includes a mounting bracket 34, a mounting plate 35, an electric push rod 36 and a wiping plate 37. The upper end of the hollow column 1 is connected to the mounting bracket 34. The top of the mounting bracket 34 is connected to the mounting plate 35. The middle of the top of the mounting plate 35 is connected to the electric push rod 36. The front end of the telescopic rod of the electric push rod 36 is connected to the wiping plate 37. The bottom of the wiping plate 37 contacts the top of the solar panel 9. The electric push rod 36 is inclined, and the inclination angle of the electric push rod 36 is the same as the inclination angle of the solar panel 9, so that the moving track of the wiping plate 37 can cover the top of the solar panel 9, thereby being able to better clean the solar panel 9.

[0039] As Figure 12 shown in the figure, it further includes sliding rods 38. The left and right sides of the top of the mounting plate 35 are both slidably connected to the sliding rods 38. The front ends of the sliding rods 38 are connected to the rear side of the wiping plate 37. The two sliding rods 38 jointly guide the wiping plate 37 to make the wiping plate 37 move more smoothly.

[0040] When it is necessary to clean the solar panel 9, control the telescopic rod of the electric push rod 36 to extend, drive the wiping plate 37 to move forward. The wiping plate 37 can wipe the top of the solar panel 9 and clean the garbage on the top of the solar panel 9, avoiding the reduction of the light-receiving area of the solar panel 9 caused by the garbage blocking the sunlight, ensuring the amount of solar radiation absorbed by the solar panel 9. The sliding rods 38 can guide the wiping plate 37 to make the wiping plate 37 move more smoothly.

[0041] The above are only examples of the present invention and are not used to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art in the technical field of the present specialty.
