Description

Technical Field

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

[0002] Street lights are the arteries of urban roads. Street lights are lighting facilities installed on roads to provide necessary visibility for vehicles and pedestrians at night. Street lights can improve traffic conditions, reduce driver fatigue, and help improve road capacity and ensure traffic safety. LED street lights refer to street lights made of LED lamps. They have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. They are of great significance to energy saving in urban lighting.

[0003] Due to the hot summer, frequent rains and rapid weather changes, people cannot always carry umbrellas when traveling. When people are walking or riding on relatively empty roads, if it suddenly rains heavily, they need to take shelter in time. If they continue to walk or ride in the heavy rain, the rain will not only get people wet, but also block pedestrians’ sight and easily cause accidents. On the empty roads, there are relatively few buildings except street lamps. However, most of the existing LED street lamps are just simple poles and lamp heads. They cannot block rain for pedestrians and can only provide lighting, which causes the problem of single function for street lamps and further reduces their practicality. Summary of the invention

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-11 A multifunctional intelligent LED street lamp comprises a lamp post 1, a photovoltaic panel 2 and a lamp holder 3. Four rotating support plates 11 are rotatably arranged on the lamp post 1. A waterproof cover 12 for shielding rainwater is fixedly arranged on the outer peripheral surface of the lamp post 1. One end of each rotating support plate 11 away from the lamp post 1 is fixedly connected to the waterproof cover 12. A lifting box 21 for driving each rotating support plate 11 to rotate is slidably arranged in the lamp post 1. Both sides of the lifting box 21 are fixedly connected with a first water bag 22 for storing water, and the bottom of the lifting box 21 is fixedly connected with a second water bag 23; a shielding component is rotatably arranged on the top of the lamp post 1, and a second telescopic tube 36 is fixedly connected to the lifting box 21. One end of the second telescopic tube 36 away from the lifting box 21 is fixed to the bottom of the lamp holder 3. The lifting box 21 drives each rotating support plate 11 to open the waterproof cover 12 through the gravity of rainwater, and at the same time, the shielding component rotates to shield the photovoltaic panel 2; the photovoltaic panel 2 and the lamp holder 3 are symmetrically arranged on both sides of the top of the lamp post 1, and the bottom end of each rotating support plate 11 is rotatably arranged in the lamp post 1, such as Figure 2As shown, the waterproof cover 12 is set in a funnel shape, and a leaking hole 121 is opened at the bottom of the waterproof cover 12. The bottom of the waterproof cover 12 is not fixed to the rotating support plate 11 and the lamp post 1. In the initial state, each rotating support plate 11 is attached to the outer peripheral surface of the lamp post 1. At this time, the waterproof cover 12 is in a retracted state, and the shielding component is above the lamp head 3. The shielding component can shield the lamp head 3 from sunlight and dust, preventing the lamp head 3 from being directly exposed to sunlight and causing a high internal temperature, thereby affecting the service life of the LED lamp beads and chips. At the same time, it can reduce the dust falling on the cooling fins of the LED lamp, thereby ensuring the heat dissipation effect of the LED street lamp. The two first water bags 22 are symmetrically arranged on both sides of the lifting box 21, and the second water bag 23 is arranged at the bottom of the lifting box 21. When it rains, the first water bag 22 and the second water bag 23 are symmetrically arranged on both sides of the lifting box 21. The second water bag 23 is used to store water and increase gravity. A drainage hole with a smaller aperture (not marked in the figure) is provided at the bottom of the second water bag 23. When it rains heavily, rainwater falling on the photovoltaic panel 2 first flows into the second water bag 23. Since the second water bag 23 has a drainage hole at the bottom, when the water flowing into the second water bag 23 is greater than the water discharged from the second water bag 23 at the same time, the water in the second water bag 23 gradually increases. When the water in the second water bag 23 is full, the rainwater gradually flows into the first water bag 22 through the lifting box 21. When the two first water bags 22 are full, the lifting box 21, the first water bag 22, and the second water bag 23 descend by gravity. The second water bag 23 squeezes the bottom end of each rotating support plate 11 during the descent, so that each rotating support plate 11 drives the waterproof cover 12 to open. At this time, the waterproof cover 12 can protect pedestrians under the street lamp from rain. When each second water bag 23 is full of water, it means that the rainfall at this time is large enough. There is a photovoltaic power generation chip at the bottom of the photovoltaic panel 2. Heavy rain will cause the photovoltaic panel 2 to vibrate and easily damage the photovoltaic chip. When each rotating support plate 11 rotates, it can drive the shielding component to move from the lamp head 3 to the photovoltaic panel 2, thereby protecting the photovoltaic panel 2 and at the same time allowing the heat dissipation fins on the upper surface of the lamp head 3 to be cleaned by rainwater. When the shielding component shields the photovoltaic panel 2, no rainwater on the photovoltaic panel 2 enters the second water bag 23. At this time, the water in the second water bag 23 is gradually discharged, but the water in each first water bag 22 will not be discharged. Since the opened waterproof cover 12 also has the function of storing water with its opening facing upward, When the water in the second water bag 23 gradually decreases, as long as the water collection speed of the waterproof cover 12 is greater than the water discharge speed of the leakage hole 121, the waterproof cover 12 and the rotating support plates 11 will not close. When the rain stops, the rainwater in the waterproof cover 12 is gradually discharged through the leakage hole 121. At this time, the rotating support plates 11 and the waterproof cover 12 are gradually retracted to the outer peripheral surface of the lamp post 1. Because the bottom of the lamp holder 3 has a glass plate or a transparent plastic plate, the light emitted by the LED lamp beads is emitted through the glass plate or the transparent plastic plate. When lighting at night, flying insects will stay on the glass plate or the transparent plastic plate. Since rainwater cannot wash the bottom of the lamp holder 3, after long-term use, the glass plate or the transparent plastic plate will be covered with a lot of dust and insect corpses, affecting the lighting effect of the LED street lamp.When the rotating support plate 11 contracts, it squeezes the two first water bags 22, and the rainwater in the two first water bags 22 is sprayed to the bottom of the lamp head 3 through the second telescopic tube 36, thereby cleaning the glass plate or transparent plastic plate at the bottom of the LED lamp head 3 and improving the lighting effect.

[0031] Furthermore, a quadripod 13 is fixedly provided in the lamp post 1, and the bottom of each rotating support plate 11 is rotatably connected to the quadripod 13. A pressure plate 14 is slidably provided in the lamp post 1, and four abutment rods 141 are fixedly provided on the pressure plate 14, and each abutment rod 141 is slidably connected to each rotating support plate 11 in a one-to-one corresponding manner; the quadripod 13 is fixed at the axial position of the lamp post 1, and the quadripod 13 has four side rods. The bottom of each rotating support plate 11 is rotatably connected to the corresponding side rod of the quadripod 13, and each rotating support plate 11 The bottom is provided with a long strip-shaped through groove, and each abutment rod 141 is arranged in each through groove in a one-to-one manner. When the first water bag 22 and the second water bag 23 are filled with water and move downward, they will squeeze the pressure plate 14 downward. When the pressure plate 14 moves downward, the corresponding rotating support plate 11 is rotated and opened through the abutment rods 141, so that the waterproof cover 12 is opened. When the rain stops and the rainwater in the waterproof cover 12 is gradually discharged, the pressure plate 14 moves up. At this time, the rotating support plates 11 and the waterproof cover 12 are contracted through the abutment rods 141.

[0032] Furthermore, a first fixed plate 17 is fixedly provided in the lamp post 1, and a lower pressure rod 15 is slidably provided on the first fixed plate 17. A first spring 16 is fixedly provided between the first fixed plate 17 and the pressure plate 14, and the lower pressure rod 15 is fixedly connected to the pressure plate 14; a disk for connecting the first spring 16 is fixedly provided at one end of the lower pressure rod 15 close to the pressure plate 14. When the second water bag 23 moves downward, the lower pressure rod 15 is squeezed to move downward, thereby driving the pressure plate 14 to move downward. At this time, the first spring 16 extends, and each rotating support plate 11 rotates. When the rainwater in the waterproof cover 12 is discharged, the rainwater in the second water bag 23 is also discharged. At this time, the first spring 16 contracts, and the lower pressure rod 15 and the pressure plate 14 are raised through the first spring 16, so that each rotating support plate 11 is again attached to the outer peripheral surface of the lamp post 1. It should be noted that the first water bag 22 and the second water bag 23 are water bags that can only shrink. They will not expand or bend significantly when squeezed, and the bottom of the second water bag 23 is made of hard material.

[0033] In another embodiment of the present invention, a second fixing plate 51 is fixedly arranged in the lamp post 1, a fourth spring 52 is fixedly arranged between the second fixing plate 51 and the lifting box 21, two limiting frames 31 are fixedly arranged on the outer circumference of the lamp post 1, and limiting rods 32 are slidably arranged in each limiting frame 31, and third springs 35 are fixedly arranged between each limiting rod 32 and each limiting frame 31 in a one-to-one correspondence; Figure 6 and Fig. 9As shown, one end of each limiting rod 32 close to the lifting box 21 is set to an inclined surface. In the initial state, the inclined surfaces of the two limiting rods 32 are in contact with the bottom of the lifting box 21, and the two limiting frames 31 are symmetrically arranged. When the rainwater in the second water bag 23 and the first water bag 22 gradually increases, the gravity of the lifting box 21 gradually increases, and the force applied by the lifting box 21 to the inclined surface of the limiting rod 32 gradually increases. At this time, the fourth spring 52 is in an extended state. When the first water bag 22 and the second water bag 23 are full of water, the gravity of the lifting box 21 is greater than the sum of the oblique upward thrust applied by the third springs 35 to the lifting box 21 and the elastic force of the fourth spring 52. At this time, the lifting box 21, the first water bag 22, and the second water bag 23 move downward. When the water in the second water bag 23 is discharged, the two first water bags 22 And the total gravity of the lifting box 21 is less than the elastic force of the fourth spring 52. At this time, the lifting box 21, the second water bag 23 and the first water bag 22 are pulled up by the fourth spring 52. When the lifting box 21 is above each limit rod 32, the height of the two first water bags 22 is higher than the height when the rotating support plate 11 is retracted. When the lifting box 21 rises to abut against the bottom of the limit rod 32, it no longer moves up. At this time, the height of the lifting box 21 and each first water bag 22 is slightly lower than the height of the retracted rotating support plate 11. When the rotating support plate 11 is retracted, the two first water bags 22 will be squeezed, so that the water in the first water bag 22 is sprayed onto the glass plate of the lamp holder 3 through the second telescopic tube 36. The end of the second telescopic tube 36 away from the lifting box 21 opens toward the glass plate of the lamp holder 3.

[0034] The cam 33 is provided with a plurality of movable members 34 on both sides of the movable members 34, and the movable members 34 are provided with a plurality of movable members 34 on both sides of the movable members 34. The movable members 34 are provided with a plurality of movable members 34 on both sides of the movable members 34. The movable members 34 are provided with a plurality of movable members 34 on both sides of the movable members 34. The four springs 52 drive the lifting box 21 to rise to the bottom of the limit rod 32. When the first spring 16 drives each rotating support plate 11 to retract, the two rotating support plates 11 close to the limit frame 31 abut against the corresponding first water bag 22, and squeeze the water in the first water bag 22 to the bottom of the lamp head 3. As the rotating support plate 11 rotates, the bottom of each telescopic rod 33 gradually abuts against the corresponding rotating support plate 11, and the rotating support plate 11 pushes the bottom of the telescopic rod 33 to move toward the lifting box 21. At this time, each limit rod 32 moves away from the lifting box 21. As the water in the first water bag 22 is squeezed out, the fourth spring 52 increases the pulling force of the lifting box 21. When the bottom of the limit rod 32 is separated from the lifting box 21, the lifting box 21 is quickly restored to its initial position through the fourth spring 52. Then the rotating support plate 11 is separated from the telescopic rod 33, and each rotating support plate 11 completely returns to its initial position.

[0035] In another embodiment of the present invention: a blocking plate 24 is slidably provided on the inner bottom wall of the lifting box 21, and four communicating holes 25 are provided on the blocking plate 24 and the inner bottom wall of the lifting box 21, a pushing frame 26 is fixedly provided on the bottom of the blocking plate 24, a second spring 27 is fixedly provided between the pushing frame 26 and the second water bag 23, and the pushing frame 26 is slidably connected to the second water bag 23; the top of the second water bag 23 has a non-retractable ring (not shown in the figure), and the pushing frame 26 is slidably sealed with the ring. In the initial state, one of the rotating support plates 11 abuts against the end of the pushing frame 26 away from the second water bag 23, and the connecting rod on the blocking plate 24 is in contact with the end of the pushing frame 26 away from the second water bag 23. The through hole 25 is aligned with the connecting hole on the bottom wall of the lifting box 21, and the second spring 27 is compressed. At this time, rainwater enters the second water bag 23 and can enter the first water bag 22 through the connecting hole 25. When each rotating support plate 11 is opened, the frame moves away from the second water bag 23 under the action of the second spring 27. At this time, the connecting hole 25 on the sealing plate 24 is staggered with the connecting hole 25 on the bottom wall of the lifting box 21, thereby isolating the lifting box 21 from the second water bag 23. When the water in the second water bag 23 leaks out, the water in the first water bag 22 can be preserved, thereby facilitating the cleaning of the bottom of the lamp holder 3 when the rotating support plate 11 retracts.

[0036] In another embodiment of the present invention: the shielding assembly includes a fixing frame 43 fixedly arranged on the top of the lamp post 1, and a shielding plate 41 is rotatably arranged on the fixing frame 43; in the initial state, the shielding plate 41 shields the lamp head 3, and when the rain is heavy, the rotating support plate 11 rotates to shield the pedestrians from the rain while driving the shielding plate 41 to rotate to shield the photovoltaic panel 2 from the rain, thereby preventing the electronic components under the photovoltaic panel 2 from being damaged by the heavy rain.

[0037] Specifically, two torsion springs 44 are fixedly arranged between the shielding plate 41 and the fixing frame 43, and a pull rope 42 is fixedly arranged at one end of the lower pressure rod 15 away from the pressure plate 14, and one end of the pull rope 42 away from the lower pressure rod 15 is fixedly connected to one end of the shielding plate 41 close to the fixing frame 43; the shielding plate 41 is rotatably connected to the fixing frame 43, and one end of the pull rope 42 is fixed to the rotating shaft of the shielding plate 41. When the second water bag 23 presses down the lower pressure rod 15, the shielding plate 41 is driven to rotate through the pull rope 42, and when the rotating support plate 11 is closed, the shielding plate 41 is rotated to the top of the lamp head 3 through the torsion spring 44;

[0038] A water collecting trough 29 is provided at the bottom of the photovoltaic panel 2, and a first telescopic tube 28 is fixedly connected to the bottom of the water collecting trough 29. One end of the first telescopic tube 28 away from the water collecting trough 29 is fixedly connected to the second water bag 23; one end of the first telescopic tube 28 away from the water collecting trough 29 is connected to the top of the second water bag 23. Rainwater on the photovoltaic panel 2 is collected through the water collecting trough 29, and then transported to the second water bag 23 through the first telescopic tube 28, so that the waterproof cover 12 can be automatically opened when it rains.

[0039] Working principle: When it rains heavily, rainwater falling on the photovoltaic panel 2 flows into the second water bag 23 through the first telescopic tube 28. When the first water bag 22 and the second water bag 23 are filled with rainwater, the lifting box 21 moves down. At this time, the limit rod 32 moves outward, and the fourth spring 52 stretches. As the second water bag 23 moves down, the second water bag 23 presses down the pressing rod 15 to drive the pressure plate 14 to move down. When the pressure plate 14 moves down, the abutting rod 141 is used to expand each rotating support plate 11 outward, thereby driving the waterproof cover 12 to open. At this time, the rainwater around the lamp post 1 can be shielded. When the rotating support plate 11 is opened, the push frame 26 moves, thereby isolating the first water bag 22 from the lifting box 21. At this time, the water in the first water bag 22 will not be discharged. When the pressing rod 15 is pressed down, the water in the first water bag 22 will not be discharged. When moving downward, the pull rope 42 is used to rotate the shielding plate 41 originally used to shield the lamp head 3 to between the photovoltaic panels 2, so as to protect the electronic devices under the photovoltaic panels 2. When the rain stops, the first spring 16 drives the lower pressure rod 15 and the pressure plate 14 to move upward, so that the rotating support plate 11 drives the waterproof cover 12 to close. When closing, the rotating support plate 11 squeezes the first water bag 22, so that the water in the first water bag 22 is sprayed on the bottom of the lamp head 3 to clean the glass plate at the bottom of the lamp head 3. As the rotating support plate 11 is retracted, the limit rod 32 is moved outward again through the contact between the telescopic rod 33 and the rotating support plate 11. At this time, the lifting box 21 is pulled back to the initial position by the fourth spring 52, and the shielding plate 41 also returns to the initial position, which is convenient for use next time it rains.

[0040] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
