Energy-saving street lamp

Abstract

This invention discloses an energy-saving street light designed to address the problem of easily damaged solar photovoltaic panels in areas with high wind speeds. The street light includes a mounting pole, a lamp body, and a specially designed energy-saving device. The energy-saving device integrates a lifting mechanism, a folding photovoltaic panel assembly, a drive mechanism, and a clutch mechanism. When wind speeds are high, the photovoltaic panel assembly is controlled by the drive mechanism to fold laterally and simultaneously flip upwards to a vertical position. Then, the clutch mechanism switches the drive, allowing the folded photovoltaic panel assembly to be retracted into the mounting pole via the lifting mechanism, effectively preventing wind damage. This design not only improves the energy-saving effect of the street light but also significantly enhances its adaptability and durability under harsh weather conditions, ensuring nighttime lighting needs in remote or mountainous areas.

Description

Technical Field

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

[0002] Energy-saving streetlights, as an important component of modern urban and rural road lighting, not only perform basic lighting functions, but also supplement or replace traditional electricity by integrating renewable energy technologies such as solar photovoltaic panels, thereby significantly reducing energy consumption and carbon emissions.

[0003] However, in the existing technology, energy-saving street lights, especially those equipped with solar photovoltaic panels, face significant challenges when applied in remote mountainous areas or areas with strong winds. Because photovoltaic panels are large in area and are mostly installed at an angle to maximize the reception of sunlight, they are easily damaged by the large area of ​​force when encountering strong winds. Moreover, maintenance is often inconvenient in remote areas, and regular inspections are difficult to guarantee in a timely manner, resulting in gaps in nighttime lighting and causing great inconvenience to local residents traveling at night.

[0004] Therefore, it is particularly important to develop an energy-saving street light that can effectively protect photovoltaic panels in strong winds. Summary of the Invention

[0015] Preferably, the clutch mechanism includes a vertical plate fixed on a fixed frame and having a traction groove, a lifting seat slidably disposed in the traction groove, a curved groove being formed on the slide, the end of the lifting seat away from the traction groove being slidably fitted into the curved groove, the traction groove having two horizontal sections, and the two horizontal sections being connected by an inclined section.

[0037] like Figure 1-11 As shown, this invention provides an energy-saving street light 3, including a mounting pole 1 and a light 3 mounted on the mounting pole 1. A wind sensor is also installed on the mounting pole 1. In areas with high and frequent winds, when using street lights 3 with solar power generation capabilities, the large area of ​​the solar panels, often installed at an angle, means that the large area exposed to strong winds can easily lead to damage. Furthermore, in remote locations, immediate repairs are difficult, often requiring periodic maintenance. This results in nighttime lighting gaps in these areas, making nighttime travel inconvenient for people in remote or mountainous regions. Therefore, to solve this problem, the energy-saving street light 3 also includes features to effectively protect the solar photovoltaic panels 4 in windy conditions.

[0038] The lifting mechanism is installed in the storage cavity 2 outside the mounting rod 1. The lifting mechanism is mounted on the turntable 27 via the lifting frame 35. The turntable 27 is provided with a crossbeam 5 and a fixed frame 24. A folding frame 8 is rotatably mounted on the fixed frame 24. It should be noted that the specific connection between the folding frame 8 and the fixed frame 24 is that plates are welded to the bottom of both the folding frame 8 and the fixed frame 24. The two plates are rotatable relative to each other. This allows the folding frame 8 and the fixed frame 24 to rotate even with a certain gap between them.

[0039] Several photovoltaic panels 4 are connected to each other by hinges 6. One photovoltaic panel 4 at one end is mounted on the fixing frame 24, and another photovoltaic panel 4 at the other end is set on the tightening mechanism and attached to the end of the folding frame 8. Here, the photovoltaic panels 4 are modularly set, abandoning the design of using a whole photovoltaic panel 4. These long strip modular photovoltaic panels 4 are connected to each other by hinges 6, so that multiple photovoltaic panels 4 can be folded from a flat state to a folded state, reducing the overall area.

[0040] A drive mechanism is mounted on the slide 36, which is slidably mounted on the lifting frame 35. The drive mechanism is connected to the tightening mechanism. When the drive mechanism is activated, the tightening mechanism drives the end photovoltaic panels 4 to move closer to the fixed frame 24, causing the photovoltaic panels 4 to fold laterally and detach from the folding frame 8. The turntable 27 is connected to the tightening mechanism via an elastic connector. When the photovoltaic panels 4 fold laterally, the turntable 27 drives the crossbeam 5 and the fixed frame 24 to rotate upwards via the elastic connector, achieving synchronous folding and rotation of the photovoltaic panels 4. As the wind gradually increases... The wind sensor uses a preset threshold, such as wind force level 10 or higher. At this time, the wind sensor controls the start of the drive mechanism through the controller. The drive mechanism uses the tightening mechanism to fold several photovoltaic panels 4 laterally until several photovoltaic panels 4 are folded through the hinge 6. At this time, all photovoltaic panels 4 are detached from the folding frame 8 and are folded. They are all attached to the position of the fixed frame 24. At the same time, through the set elastic connector, the crossbeam 5 and the fixed frame 24 are also flipped upward until the maximum stroke is reached. At this time, the lateral folding of multiple modular photovoltaic panels 4 and the erection of the folded photovoltaic panels 4 are completed.

[0041] A clutch mechanism is mounted on a fixed frame 24, and a lifting seat 21 is mounted on the clutch mechanism. When the photovoltaic panel 4 is folded horizontally and flipped upward to its maximum stroke, the clutch mechanism is used to disengage the drive mechanism from the tightening mechanism and connect it to the lifting mechanism, so that the folded photovoltaic panel 4 moves vertically into the storage cavity 2. At this time, the clutch mechanism disengages the drive mechanism from the tightening mechanism and connects it to the lifting mechanism, so that the folded photovoltaic panel 4 is put into the storage cavity 2 by the lifting mechanism to prevent damage to the photovoltaic panel 4 in the event of strong winds, thereby preventing the occurrence of abnormal lighting problems in remote areas or mountainous areas.

[0042] In one embodiment of the present invention, the tightening mechanism includes a gear disk 26 rotatably mounted on a lifting frame 35, a lead screw 29 mounted on the gear disk 26, and a lead screw 13 mounted on the lead screw 29 after extending into the fixed frame 24 via a shaft. A lead screw 9 is mounted on the lead screw 13 via a universal joint 33. A lead screw nut 10 is threaded onto the lead screw 9. The photovoltaic panel 4 at the end is mounted on the lead screw nut 10. When excessive wind force is detected, the drive mechanism is activated, causing the gear disk 26 to rotate, thereby causing the lead screw 29, lead screw 13, and lead screw 9 to rotate synchronously. When the lead screw 9 rotates, the lead screw nut 10 moves, thereby pulling the photovoltaic panel 4 at the end to move, thus realizing the folding of the photovoltaic panel 4.

[0043] Since there is a gap between the folding frame 8 and the fixed frame 24, the gap size is smaller than the width of the screw block 10, and the side view section diameter of the universal shaft 33 is smaller than the side view section diameter of the lead screw 9 and the lead screw 13, and the length of the universal shaft 33 is smaller than the width of the screw block 10, and the lead screw 9 and the lead screw 13 have the same specifications, the screw block 10 can be moved from the lead screw 9 to the lead screw 13 when it moves. Here, the gap between the folding frame 8 and the fixed frame 24 and the design of the universal shaft 33 will not affect the movement of the screw block 10. When the screw block 10 moves from the lead screw 9 to the lead screw 13, it moves all the photovoltaic panels 4 to the position where they abut against the fixed frame 24, and at this time the folding of all the photovoltaic panels 4 is completed.

[0044] When the photovoltaic panel 4 is folded, it is also necessary to gradually stand it up. In another embodiment of the present invention, the elastic connector includes a plug 25 that is spring-loaded on the outer surface of the lead screw 29. The turntable 27 is sleeved on the outside of the lead screw 29, and the plug 25 is inserted into a slot on the turntable 27. A connecting frame 31 is also threaded onto the lead screw 29, and the end of the connecting frame 31 is inserted into the fixing frame 24. The shaft of the end of the photovoltaic panel 4 connected to the fixing frame 24 extends to the fixing frame 24. The transverse block 30 is installed inside the frame 24 via a spring, with the end of the transverse block 30 abutting against the surface of the connecting frame 31. The other side of the connecting frame 31 abuts against the surface of the insert block 25. The photovoltaic panel 4 gradually folds, meaning the drive mechanism is in the activated state at this time. The lead screw 4 29 on the tightening mechanism rotates, and the connecting frame 31 moves away from the turntable 27 through the threaded structure with the lead screw 4 29. The spring gradually returns to its original deformation, carrying the insert block 25 away from the slot on the turntable 27. When the insert block 25 is inserted into the slot, the insert block 25 and the slot... A transmission mechanism is formed, causing the turntable 27 to rotate, which in turn causes the crossbeam 5 and the fixing frame 24 to flip, thereby gradually raising the photovoltaic panel 4 during the folding process. After the photovoltaic panel 4 is raised, that is, when it reaches the angle that can enter the storage cavity 2, the connecting frame 31 moves to disengage the insert 25 from the slot. At this time, the rotation of the lead screw 29 on the turntable 27 is released, and the turntable 27 stops rotating, thereby fixing the angle of the photovoltaic panel 4 after it is raised. Then, through the continuous drive of the drive mechanism, the photovoltaic panel 4 is folded until it is completed. During the folding of the photovoltaic panel 4, the elastic connector can raise the photovoltaic panel 4 during the folding process. Since the stroke during the folding process is much greater than that during the raising process, after the raising is completed, the elastic connector releases the transmission of the lead screw 29 on the turntable 27, thereby fixing the angle of the photovoltaic panel 4 after it is raised. Then, through the drive device, the photovoltaic panel 4 can continue to be folded laterally until it is folded to the maximum stroke.

[0045] It should be noted that a stretcher 11 is fixedly installed on the lifting frame 35, and a stretcher 2 12 is installed on the shell of the storage cavity 2. When the photovoltaic panel 4 is in the unfolded state, that is, in normal use, the crossbeam 5 rests on the stretcher 2 12, thereby supporting the crossbeam 5 and the photovoltaic panel 4 on the fixed frame 24 and the folding frame 8, reducing the pressure on the turntable 27 and the insert block 25, which is suitable for long-term use. When the photovoltaic panel 4 is erected to the maximum stroke, the crossbeam 5 abuts against the surface of the stretcher 11, thereby fixing the erection angle of the photovoltaic panel 4. That is to say, the crossbeam 5 is not vertical, but has a certain angle, so that after the crossbeam 5 is erected, it is similar to leaning against the crossbeam 5. The specific angle is not required, as long as the photovoltaic panel 4 can enter the storage cavity 2 after descending.

[0046] When the photovoltaic panel 4 is folded, the folding action of the photovoltaic panel 4 can be terminated by the clutch mechanism. In one embodiment of the present invention, the clutch mechanism includes a vertical plate 17 fixed on the fixed frame 24 and having a pull groove 19. A lifting seat 21 is slidably arranged in the pull groove 19. A curved groove 42 is provided on the slide 36. The end of the lifting seat 21 away from the pull groove 19 is slidably fitted into the curved groove 42. The pull groove 19 has two horizontal sections, and the two horizontal sections are connected by an inclined section. The clutch mechanism also includes a lead screw 20 and a rotating rod 22. The lifting seat 21 is threadedly connected to the lead screw 20. The end of the lead screw 20 is set as an opening, and a sliding rod 18 is slidably arranged in the opening. The rotating rod 22 is connected to the drive mechanism and has a hollow structure. A push plate 23 is fixedly arranged on the inner end surface. When the photovoltaic panel 4 is folded laterally, the lead screw block 10 moves against the lifting seat 21, realizing the action of the sliding rod 18 being inserted into the rotating rod 22.

[0047] When the photovoltaic panel 4 is folded using the nut block 10, the nut block 10, upon moving onto the lead screw 13, pushes the lifting seat 21. The lifting seat 21 moves in the horizontal section above the traction groove 19, causing the lead screw 20 to move closer to the rotating rod 22 until it is inserted into the inside of the rotating rod 22. Since the rotating rod 22 is connected to the drive mechanism, the drive mechanism is in the activated state at this time. After the lead screw 20 is inserted into the rotating rod 22, the push plate 23 pushes the slide rod 18 to rotate the lead screw 20. As the lead screw 20 rotates, it causes the lifting seat 21 to slide, moving from the upper horizontal section of the traction groove 19 to the lower section via the inclined section. Within the horizontal section, that is, the entire lifting seat 21 tilts downward a certain distance, so that the slide 36 can be pulled downward by the screw 20 and the rotating rod 22 that are inserted into each other and the lifting seat 21 that is tilted downward. This causes the entire drive mechanism to move downward. The downward-moving drive mechanism is separated from the tightening mechanism and then connected to the lifting mechanism. At this time, the photovoltaic panel 4, which is folded and erected at a certain angle, can be put into the storage cavity 2 by the lifting mechanism. Here, a cover plate can also be installed at the end of the crossbeam 5. After the crossbeam 5 and the photovoltaic panel 4 have all entered the storage cavity 2, the cover plate closes the top opening of the storage cavity 2 to prevent water from entering.

[0048] It should be noted that the lead of lead screw 20 is designed to be self-locking, which means that when lead screw nut 10 pushes lifting seat 21 to move, it will not cause lead screw 20 to rotate in the opposite direction.

[0049] It should be noted that when the push plate 23 pushes the slide rod 18 to rotate, the slide rod 18 rotates to the lower half of the lead screw 20. At this time, under the influence of gravity, the slide rod 18 moves downward and disengages from the push plate 23. At this time, even if the rotating rod 22 continues to rotate, it will not cause the lead screw 20 to rotate again. In other words, the lead screw 20 and the rotating rod 22 are also designed to be disengaged. This prevents the lead screw 20 from continuing to rotate after the lifting seat 21 moves to the horizontal section below the traction groove 19, which would cause the lifting seat 21 to move beyond its limit.

[0050] The two ends of the slide rod 18 are both arc-shaped. This arc design is to prevent the slide rod 18 from directly abutting the push plate 23 on the rotating rod 22 when it is inserted into the rotating rod 22. If it does abut, the arc design can push the slide rod 18 upward so that it can pass over the push plate 23 and prevent it from getting stuck.

[0051] Furthermore, when the lifting seat 21 moves, a channel for the lifting seat 21 to slide is provided on the fixed frame 24. The shape of the channel is the same as that of the traction groove 19. This makes the lifting seat 21 more stable under force, with force on both ends, preventing the lifting seat 21 from being stuck due to force deviation.

[0052] It should also be noted that the purpose of the curved groove 42 on the slide 36 is as follows: Since the crossbeam 5, the fixed frame 24 and the photovoltaic panel 4 need to be rotated and erected by the turntable 27, and the lifting seat 21 is not on the same axis of rotation as the fixed frame 24 when it rotates, the lifting seat 21 will generate an arc when it rotates with the fixed frame 24. The curvature of this arc is the same as the curvature of the curved groove 42. Thus, the curved groove 42 adapts to the rotation of the lifting seat 21. The slide 36 and the lifting frame 35 are designed with damping. Only when the force of the lifting seat 21 pressing down on the curved groove 42 overcomes the damping force will the slide 36 descend. Under normal conditions, the damping force is greater than the weight generated by the slide 36 and the drive mechanism.

[0053] In another embodiment of the present invention, the drive mechanism includes a motor 14 mounted on a slide 36, a worm gear 37 mounted on the motor 14, and a gear disk 39 rotatably mounted on the slide 36 on the worm gear 37. The gear disk 39 meshes with a gear disk 26, so that the gear disk 26 can rotate when the motor 14 is started. The drive mechanism also includes a gear disk 38 rotatably mounted on the slide 36 and connected to the worm gear 37. A cone is provided on the rotation axis of the gear disk 38. Gear 2 16; The lifting mechanism includes a lead screw 5 41 rotatably installed in the storage cavity 2. The lifting frame 35 is threadedly connected to the lead screw 5 41 through a screw sleeve 34. A bevel gear 15 is set on the screw sleeve 34 at the position corresponding to the bevel gear 2 16. After the slide 36 is pressed down by the lifting seat 21, the gear plate 39 separates from the gear plate 1 26, and the bevel gear 15 meshes with the bevel gear 2 16, thereby causing the screw sleeve 34 to rotate and drive the lifting frame 35 to move down into the storage cavity 2.

[0054] Since bevel gear 16 and slide 36 are integrally set, while bevel gear 15 is integrally set with lifting frame 35 via screw sleeve 34, when the lifting seat 21 presses the slide 36 and bevel gear 15 and bevel gear 26 mesh, and the lifting frame 35 is lowered as a whole, the turntable 27 also lowers the crossbeam 5 and the fixed frame 24 as a whole, thereby lowering the vertical plate 17 as a whole. In this way, the lifting seat 21 lowers the slide 36 as a whole, so that bevel gear 15 and bevel gear 26 will also lower synchronously as a whole without separation.

[0055] After the windy weather ends, the photovoltaic panel 4 needs to be re-expanded. At this time, the motor 14 is driven in reverse by the control device. The screw sleeve 34 rotates in reverse, driving the lifting frame 35 to rise as a whole until it moves to the highest position. During this process, since the outer peripheral surface of the lead screw 20 away from the slide rod 18 is provided with teeth, and the rack 7 is fixedly installed at the position of the corresponding teeth in the storage cavity 2, when the teeth mesh with the rack 7, the lead screw 20 rotates, thereby causing the slide rod 18 to rotate upward. Under the influence of gravity, it again abuts against the push plate 23. The push plate 23 pushes the slide rod 18 to rotate in reverse, thereby causing the lifting seat 21 to move in reverse to the initial position. At this time, the bevel gear 15 disengages from the bevel gear 26, and the gear disk 16 meshes with the gear disk 39. At this time, the lead screw 9 rotates, and the photovoltaic panel 4 is re-expanded through the lead screw block 10.

[0056] It should be noted that the screw 29 is constructed such that the half near the turntable 27 has a spiral pattern, while the part away from the turntable 27 does not. When storing the photovoltaic panel 4, as the screw 29 rotates, the spring on the insertion block 25 returns to its original deformation, and the insertion block 25 is separated from the turntable 27. Due to the design of the screw 29, the continuous rotation of the screw 29 during the storage of the photovoltaic panel 4 will cause the spiral patterned part of the screw 29 to separate from the connecting frame 31. At this time, the rotation of the screw 29 will not cause any damage to the connecting frame 31. Driven by the mother block 10, when the photovoltaic panel 4 is unfolded by the mother block 10 to make the photovoltaic panel 4 on the fixed frame 24 rotate, the transverse block 30 will rotate. The transverse block 30 will push the connecting frame 31 by rotating, so that the connecting frame 31 will push the insert 25 to be inserted into the slot on the turntable 27. In order to make the insert 25 easy to insert, the insert 25 is elastically set. After the insert 25 is inserted into the slot, the turntable 27 rotates in the opposite direction, so that the crossarm 5 and the photovoltaic panel 4 are flipped to the unfolded state. At this time, the photovoltaic panel 4 is unfolded again.

[0057] It should also be noted that both the lifting seat 21 and the wire nut block 10 are made of permanent magnet material. When the wire nut block 10 unfolds with the photovoltaic panel 4 at the end, it will pull the lifting seat 21 and the lead screw 20 on it to move, so that the lead screw 20 will disengage from the rotating rod 22 and return to its original position. This continues until the lifting seat 21 moves to its maximum stroke, which is the edge of the pulling groove 19, and can no longer move. The lifting seat 21 then disengages from the wire nut block 10, and all components return to their original positions for the next storage of the photovoltaic panel 4.

[0058] It should be noted that the transverse block 30 is mounted on the rotating shaft of the photovoltaic panel 4 on the fixed frame 24 via a spring. When the photovoltaic panel 4 is in the unfolded state, the transverse block 30 is horizontal. Then, during the process of folding the photovoltaic panel 4, when the lead screw 29 rotates, the connecting frame 31 moves, pushing the spring on the transverse block 30 to contract, causing the transverse block 30 to move. Then, the photovoltaic panel 4 is folded horizontally. At this time, the shaft of the photovoltaic panel 4 connected to the fixed frame 24 rotates, and the transverse block 30 rotates to a vertical state. When the photovoltaic panel 4 is unfolded, since the transverse block 30 is vertical and the spring is also vertical, when it rotates and abuts against the connecting frame 31, the spring on the transverse block 30 will not immediately deform, but will generate a lateral thrust. This lateral thrust can reconnect the connecting frame 31 to the lead screw 29.

[0059] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, 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 foregoing 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.
