[0002] A solar LED street lamp is a road lighting device that uses solar energy to generate electricity. It uses an LED lamp as a light source.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) For this multi-illumination unit solar LED street lamp, when in bad weather such as heavy rain, heavy snow or hail, first drive the first toothed plate to rise by the second servo cylinder so that the first toothed plate is in a meshing relationship with the first transmission gear. Then, drive the threaded rod to rotate by operating the servo motor. When the threaded rod rotates, it can drive the two sliding blocks to move in opposite directions. When the sliding blocks move, they can drive the first toothed plate to move through the second servo cylinder, and then the first toothed plate can drive the first transmission gear to rotate. When the first transmission gear rotates, it can drive the rotating shaft to rotate, and then drive the protective frame to rotate. By controlling the rotation direction of the servo motor, the protective frame is rotated to the upper surface of the support rod. At this time, the support rod can support the protective frame, so that the protective frame covers and protects the solar panel mounting frame, and then protects the solar panels on the upper surface of the solar panel mounting frame and the solar panels inside the two protective frames. In normal weather, the servo motor can drive the two protective frames to unfold, and at this time, the opening area of the solar panels can be enlarged, and more solar energy can be collected.

[0015] (2) For this multi-illumination unit solar LED street lamp, the cleaning mechanism can clean the solar panels on the upper surface of the solar panel mounting frame and the solar panels on the lower surface of the protective frame. When the two protective frames cover and protect the solar panel mounting frame, drive the first toothed plate to descend by operating the second servo cylinder, so that the first toothed plate disengages from the first transmission gear and at the same time, the second toothed plate engages with the second transmission gear. At this time, when the servo motor rotates and drives the sliding block to move under the action of the threaded rod, it can drive the second toothed plate to move. The movement of the second toothed plate can make the second toothed plate drive the second transmission gear to rotate, and then drive the rotating rod to rotate.

[0016] (3) For this kind of solar LED street lamp with multiple lighting units, in case of hail weather, when the two groups of protective frames cover and protect the solar panel mounting frame, the hail will collide with the protective plate at the upper end of the protective frame. At this time, under the action of the moving slider and the second hinge rod, the damping slider will slide on the circumferential surface of the damping slide rod and compress the buffer spring. Among them, under the action of the buffer spring, it can buffer when the protective plate is collided. After buffering, the protective plate enhances the protection effect of the protective plate and also protects the protective plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 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.

[0027] Embodiment 1:

[0028] Please refer to Figures 1-8 , the present invention provides a solar LED street lamp with multiple lighting units, including an adjustment mechanism 10. A protection mechanism 20 is provided at the upper end of the adjustment mechanism 10. A buffer assembly 30 is provided inside the protection mechanism 20. A cleaning mechanism 40 is provided at the upper end of the adjustment mechanism 10. The adjustment mechanism 10 includes a lamp post 11. An LED street lamp body 12 is provided on the side of the lamp post 11. A first rotating seat 13 is provided on the upper surface of the lamp post 11. A solar panel mounting bracket 14 is provided at the upper end of the lamp post 11, and the solar panel mounting bracket 14 is rotatably connected to the first rotating seat 13. A solar panel is installed on the upper surface of the solar panel mounting bracket 14. A slide rail 15 is provided on the side of the lamp post 11. Slide rails 15 are installed on both side ends of the lamp post 11. A first slide bar 17 is provided inside the slide rail 15. A sliding hinge block 18 is slidably connected to the circumferential surface of the first slide bar 17. A first servo cylinder 16 is provided on the side of the slide rail 15, and the output end of the first servo cylinder 16 is connected to the sliding hinge block 18. A hinge seat 110 is provided on the lower surface of the solar panel mounting bracket 14. A first hinge rod 19 is hinged between the sliding hinge block 18 and the hinge seat 110.

[0029] It should be noted that the solar panel mounting frame 14 can adjust the position of the solar panel on the upper surface of the solar panel mounting frame 14 according to the rising and setting of the sun, so that the solar panel surface can always face the vertical direction of the sun, ensuring that the solar panel can always obtain solar energy to the maximum extent, that is, the first servo electric cylinder 16 can be operated to drive the sliding hinge block 18 to slide inside the first slide rod 17. When the sliding hinge block 18 slides, under the action of the first hinge rod 19 and the hinge seat 110, the solar panel mounting frame 14 can be pulled or pushed to rotate in the first rotating seat 13, wherein the slide rail 15, the first servo electric cylinder 16, the first slide rod 17, the sliding hinge block 18, the first hinge rod 19, and the hinge seat 110 are symmetrically arranged with the lamp post 11 as the center. When the solar panel mounting frame 14 rotates, the working mode of the two first servo electric cylinders 16 is that one performs extension output and the other performs contraction output, thereby completing the angle adjustment of the solar panel mounting frame 14 in the first rotating seat 13, so that the solar panel surface can be rotated to the vertical direction facing the sun.

[0030] The protection mechanism 20 includes a sliding box 21, and the sliding box 21 is arranged on the side of the solar panel mounting frame 14. The interior of the sliding box 21 is rotatably connected to a threaded rod 22. A servo motor 23 is arranged on the side of the sliding box 21, and the output end of the servo motor 23 is transmission-connected to the threaded rod 22. The circumferential surface of the threaded rod 22 is threadedly connected to a sliding block 24. A second servo electric cylinder 25 is arranged on the side of the sliding block 24. The output end of the second servo electric cylinder 25 is connected to a first tooth plate 26 through a connecting plate. A supporting side plate 28 is arranged on the side of the solar panel mounting frame 14. The supporting side plate 28 is arranged on the side of the solar panel mounting frame 14. A rotating frame 29 is provided on the upper surface of the plate 28, and a rotating shaft 210 is rotatably connected inside the rotating frame 29. A protective frame 212 is provided on the circumferential surface of the rotating shaft 210, and a solar panel is installed on the inner side of the protective frame 212. The circumferential surfaces at both ends of the rotating shaft 210 are transmission-connected with a first transmission gear 211, and the first transmission gear 211 can be meshed and connected with the first tooth plate 26. A support rod 213 is provided on the upper surface of the supporting side plate 28. Two groups of protective mechanisms 20 are provided on the side of the solar panel mounting frame 14, and a transmission belt 27 is transmission-connected between the two threaded rods 22.

[0031] It should be noted that in case of bad weather, such as heavy rain, heavy snow or hail, etc., first, the second servo cylinder 25 is driven to drive the first toothed plate 26 to rise, so that the first toothed plate 26 is in a meshing relationship with the first transmission gear 211. Then, the servo motor 23 is operated to drive the threaded rod 22 to rotate. The threads on the circumferential surface of the threaded rod 22 are divided by the midpoint, and the thread directions on both sides are opposite, and sliding blocks 24 are threadedly connected to the threads on both sides. Therefore, when the threaded rod 22 rotates, it can drive the two sliding blocks 24 to move in opposite directions. When the sliding block 24 moves, it can drive the first toothed plate 26 to move through the second servo cylinder 25, and then the first toothed plate 26 can drive the first transmission gear 211 to rotate. When the first transmission gear 211 rotates, it can drive the rotating shaft 210 to rotate, and then drive the protective frame 212 to rotate. By controlling the rotation direction of the servo motor 23, the protective frame 212 is rotated to the upper surface of the support rod 213. At this time, the support rod 213 can support the protective frame 212. Since there are two sets of protection mechanisms 20 and they are linked by a transmission belt 27, when one set works, the other set will also work. Since the protective frames 212 in the two sets of protection mechanisms 20 are arranged in a buttressing manner, and the threads on the circumferential surface of the threaded rod 22 are divided by the midpoint, and the thread directions on both sides are opposite, and sliding blocks 24 are threadedly connected to the threads on both sides. Therefore, when one set of protective frames 212 is driven by the servo motor 23 to rotate to the upper surface of the support rod 213, the other set will also rotate to the upper surface of the corresponding support rod 213. At this time, the two sets of protective frames 212 can cover and protect the solar panel mounting frame 14, and thus protect the solar panels on the upper surface of the solar panel mounting frame 14 and the solar panels inside the two sets of protective frames 212. In case of normal weather, the servo motor 23 can be driven to expand the two sets of protective frames 212. At this time, the opening area of the solar panels can be enlarged, and more solar energy can be collected.

[0032] An installation groove is provided inside the protective frame 212, and the buffer assembly 30 is arranged inside the installation groove. The buffer assembly 30 includes a limit rail 31, and the limit rail 31 is arranged on the inner bottom wall of the installation groove. Mounting seats 32 are provided on the surfaces at both ends of the limit rail 31. A damping slide bar 33 is arranged between the two mounting seats 32. A damping slider 34 is slidably connected to the circumferential surface of the damping slide bar 33, and the damping slider 34 is slidably connected to the limit rail 31. A buffer spring 35 is arranged between the damping slider 34 and the mounting seat 32. A protective plate 37 is slidably connected inside the installation groove. A second slide bar 38 is provided on the lower surface of the protective plate 37. A moving slider 39 is slidably connected to the circumferential surface of the second slide bar 38. A second hinge rod 36 is arranged between the moving slider 39 and the damping slider 34.

[0033] It should be noted that in the event of hail weather, when the two sets of protective frames 212 cover and protect the solar panel mounting frame 14, the hail will collide with the protective plate 37 at the upper end of the protective frame 212. At this time, under the action of the moving slider 39 and the second hinge rod 36, the damping slider 34 will slide on the circumferential surface of the damping slide rod 33 and compress the buffer spring 35. Among them, under the action of the buffer spring 35, it can buffer the collision suffered by the protective plate 37. After the protective plate 37 is buffered, while increasing the protection effect of the protective plate 37, it also protects the protective plate 37; the sliding between the damping slider 34 and the damping slide rod 33 has a damping effect and can be effective, which can avoid the reciprocating vibration of the protective plate 37 under the action of the buffer spring 35, and at the same time increase the buffering effect of the protective plate 37.

[0034] The cleaning mechanism 40 includes a second toothed plate 41, and the second toothed plate 41 is arranged on the side surface of the first toothed plate 26 through a connecting plate. A second rotating seat 42 is provided on the upper surface of the support side plate 28. A rotating rod 43 is rotatably connected inside the second rotating seat 42. A second transmission gear 44 is provided on the circumferential surface of the rotating rod 43, and the second transmission gear 44 can be meshed with the second toothed plate 41. A cleaning frame 45 is provided on the circumferential surface of the rotating rod 43. An upper cleaning brush 46 is provided on the upper surface of the cleaning frame 45, and a lower cleaning brush 47 is provided on the lower surface of the cleaning frame 45.

[0035] It should be noted that the cleaning mechanism 40 can clean the solar panels on the upper surface of the solar panel mounting frame 14 and the solar panels on the lower surface of the protective frame 212. The working mode of the cleaning mechanism 40 is as follows: when the two sets of protective frames 212 cover and protect the solar panel mounting frame 14, by making the second servo cylinder 25 work to drive the first toothed plate 26 to descend, while the first toothed plate 26 is disengaged from the first transmission gear 211, the second toothed plate 41 is meshed with the second transmission gear 44. At this time, when the servo motor 23 rotates, under the action of the threaded rod 22, when driving the sliding block 24 to move, it can drive the second toothed plate 41 to move. The movement of the second toothed plate 41 can make the second toothed plate 41 drive the second transmission gear 44 to rotate. The rotation of the second transmission gear 44 can drive the rotating rod 43 to rotate, and then the cleaning frame 45 can be rotated. When the cleaning frame 45 rotates, the upper cleaning brush 46 can clean the solar panels on the lower surface of the protective frame 212 and the lower cleaning brush 47 can clean the solar panels on the upper surface of the solar panel mounting frame 14.

[0036] Embodiment 2:

[0037] An environmental detection unit is provided inside the solar panel mounting frame 14 to control the cleaning of the cleaning mechanism 40. The specific steps are as follows;

[0038] 101: When receiving the environmental monitoring and acquisition instruction, the particulate matter sensor is used to acquire the particulate matter concentration in the environment where the solar panel mounting bracket 14 is located.

[0039] 102: When the particulate matter concentration is greater than the preset concentration threshold, the cleaning mechanism 40 is controlled to perform the cleaning work.

[0040] 103: Taking the acquisition time as the abscissa and the particulate matter concentration as the ordinate, a two-dimensional rectangular coordinate system is constructed. Then, the particulate matter concentration is input into the coordinate system according to the corresponding acquisition time. The position of the particulate matter concentration in the coordinate system is recorded as the concentration point. The concentration points are connected in sequence to obtain the relationship diagram of the particulate matter concentration changing with time. The slope Ki of the line segment formed by adjacent concentration points is calculated, where i = 1, 2, 3... n, n represents the total number of slopes, and i represents the serial number of any one slope. The particulate matter concentrations at different acquisition times are averaged to obtain the concentration mean value b; using the formula the fluctuation value s is obtained, where d1 and d2 are respectively set weight coefficients. When the fluctuation value s is greater than the set fluctuation threshold, the interval coefficient is divided by the fluctuation value s to obtain the latest acquisition interval. An environmental detection and acquisition instruction is generated based on the latest acquisition interval and updated to step 101. It can be seen from the formula that the greater the fluctuation value s, the greater the degree of environmental change, and at this time, the generated acquisition interval is smaller.

[0041] The working principle and usage process of the present invention:

[0042] Step 1, the solar panel mounting bracket 14 can adjust the position of the solar panel on the upper surface of the solar panel mounting bracket 14 according to the rising and setting of the sun, so that the solar panel surface can always face the vertical direction of the sun, ensuring that the solar panel can always obtain solar energy to the maximum extent. That is, by making the first servo cylinder 16 work to drive the sliding hinge block 18 to slide inside the first sliding rod 17. When the sliding hinge block 18 slides, under the action of the first hinge rod 19 and the hinge seat 110, the solar panel mounting bracket 14 can be pulled or pushed to rotate within the first rotating seat 13. When the solar panel mounting bracket 14 rotates, the working modes of the two first servo cylinders 16 are that one extends and outputs, and the other contracts and outputs, so as to complete the angle adjustment of the solar panel mounting bracket 14 within the first rotating seat 13, enabling the solar panel surface to rotate to the vertical direction facing the sun.

[0043] Step 2: When inclement weather such as heavy rain, heavy snow or hail is required, first drive the first toothed plate 26 to rise by the second servo cylinder 25, so that the first toothed plate 26 is in a meshing relationship with the first transmission gear 211. Then, drive the threaded rod 22 to rotate by operating the servo motor 23. When the threaded rod 22 rotates, it can drive the two sliding blocks 24 to move in opposite directions. When the sliding blocks 24 move, they can drive the first toothed plate 26 to move through the second servo cylinder 25. Furthermore, the first toothed plate 26 can drive the first transmission gear 211 to rotate. When the first transmission gear 211 rotates, it can drive the rotating shaft 210 to rotate, and then drive the protective frame 212 to rotate. By controlling the rotation direction of the servo motor 23, the protective frame 212 is rotated to the upper surface of the support rod 213. At this time, the support rod 213 can support the protective frame 212. When one set of protective frames 212 is rotated to the upper surface of the support rod 213 under the driving action of the servo motor 23, the other set will also rotate to the upper surface of the corresponding support rod 213. At this time, the two sets of protective frames 212 can cover and protect the solar panel mounting frame 14, and thus protect the solar panels on the upper surface of the solar panel mounting frame 14 and the solar panels inside the two sets of protective frames 212. In normal weather, the two sets of protective frames 212 can be driven by the servo motor 23 to expand, and at this time, the opening area of the solar panels can be increased, and thus more solar energy can be collected;

[0044] Step 3: In the event of hail, when the two sets of protective frames 212 cover and protect the solar panel mounting frame 14, the hail will collide with the protective plate 37 at the upper end of the protective frame 212. At this time, under the action of the moving slider 39 and the second hinge rod 36, the damping slider 34 will slide on the circumferential surface of the damping slide rod 33 and compress the buffer spring 35. Among them, under the action of the buffer spring 35, it can buffer the impact when the protective plate 37 is collided. After the buffer of the protective plate 37, while increasing the protection effect of the protective plate 37, it also protects the protective plate 37;

[0045] Step 4: The cleaning mechanism 40 can clean the solar panels on the upper surface of the solar panel mounting frame 14 and the solar panels on the lower surface of the protective frame 212. The working mode of the cleaning mechanism 40 is as follows:

[0046] 101: When receiving the environmental monitoring and collection instruction, the particulate matter concentration of the environment where the solar panel mounting frame 14 is located is collected by using the particulate matter sensor,

[0047] 102: When the particulate matter concentration is greater than the preset concentration threshold, the cleaning mechanism 40 is controlled to perform cleaning work. That is, first, the two sets of protective frames 212 cover the solar panel mounting frame 14. Then, the second servo cylinder 25 operates to drive the first toothed plate 26 to descend, so that the first toothed plate 26 disengages from the first transmission gear 211 and at the same time the second toothed plate 41 engages with the second transmission gear 44. At this time, when the servo motor 23 rotates, under the action of the threaded rod 22, when driving the slider 24 to move, the second toothed plate 41 can be driven to move. Furthermore, the second toothed plate 41 drives the second transmission gear 44 to rotate, and the rotation of the second transmission gear 44 can drive the rotating rod 43 to rotate. Furthermore, the cleaning frame 45 can be rotated. When the cleaning frame 45 rotates, the upper cleaning brush 46 can clean the solar panels on the lower surface of the protective frame 212 and the lower cleaning brush 47 can clean the solar panels on the upper surface of the solar panel mounting frame 14.

[0048] 103: Taking the collection time as the abscissa and the particulate matter concentration as the ordinate, a two-dimensional rectangular coordinate system is constructed. Then, the particulate matter concentration is input into the coordinate system according to the corresponding collection time. The position of the particulate matter concentration in the coordinate system is recorded as the concentration point. The concentration points are connected in sequence to obtain a graph of the change of particulate matter concentration with time. The slope Ki of the line segment formed by adjacent concentration points is calculated, where i = 1, 2, 3... n, n represents the total number of slopes, and i represents the serial number of any one of the slopes. The particulate matter concentrations at different collection times are averaged to obtain the concentration average value b. Using the formula the fluctuation value s is obtained, where d1 and d2 are respectively set weight coefficients. When the fluctuation value s is greater than the set fluctuation threshold, the interval coefficient is divided by the fluctuation value s to obtain the latest collection interval. An environmental monitoring collection instruction is generated based on the latest collection interval and updated to step 101.
