Description

Technical Field

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

[0002] A solar LED street lamp is an environment-friendly street lamp that combines solar photovoltaic technology and LED lighting technology. In recent years, it has gradually gained wide popularity. It makes full use of solar energy, a renewable energy source, and has many advantages such as environmental protection, economy, safety and reliability.

[0003] According to a solar LED street lamp with a patent publication number of CN107763545B and a publication date of December 13, 2019, it includes: a solar panel, a rotating device, a lamp post, a lamp fixture assembly and a waste recycling device; the lamp fixture assembly includes an annular mounting body, a plurality of heat dissipation parts and a plurality of LED lamp cores electrically connected to the battery cell assembly. The lamp post is provided with an annular mounting groove, and the annular mounting body is coaxially sleeved in the annular mounting groove; the heat dissipation part includes a heat dissipation groove, a bi-directional memory alloy plate and a plurality of bi-directional memory alloy bars, and the waste recycling device includes a semi-annular body and three waste recycling boxes. The present invention has the following beneficial effects: When installing the solar LED street lamp, the laying of complex circuits is omitted, reducing costs; the heat dissipation efficiency is high, improving the service life of the LED lamp cores; the waste recycling device provided on the lamp post can act as an urban sanitation worker, collecting domestic waste, etc., beautifying the environment, and having practical and beneficial functions. This device can make the solar panel rotate along a preset rotation trajectory through the rotating device, thereby maximizing the conversion of light energy into electrical energy. However, it should be noted that the lamp post of this device does not have a lifting or folding function. When the lamp fixture needs to be maintained or replaced, maintenance personnel must rely on external lifting equipment to reach the position of the lamp fixture for maintenance, which not only increases the maintenance difficulty, but also brings safety hazards due to high-altitude operations, and requires additional scheduling of lifting equipment, thereby increasing the maintenance cost.

[0004] Therefore, we urgently need a solar LED street lamp that is convenient for disassembly and maintenance. Summary of the Invention

[0005] In order to overcome the above-mentioned disadvantages of the prior art, the present invention provides a solar LED street lamp that is convenient for disassembly and maintenance.

[0006] The technical solution is as follows: A solar LED street lamp that is convenient for disassembly and maintenance, including support I, support II, a pull rod, a lifting mechanism, a fixing component, and a lighting mechanism. The middle part of support I is slidably connected to support II. The lower right side of support II is connected to a pull rod. A hole groove is opened on the lower right side of support I. A lifting mechanism is provided on support II. The lifting mechanism includes a motor, a threaded rod, a connecting plate, a rotating plate I, and a rotating plate II. A motor is installed on the rear side of support II. The output shaft of the motor is connected to a threaded rod. A connecting plate is threadedly connected to the threaded rod. A rotating plate I is rotatably connected to the connecting plate. A friction damping structure is provided between the connecting plate and the rotating plate I. The upper part of the rotating plate I is rotatably connected to the rotating plate II. The other end of the rotating plate II is rotatably connected to support II. Friction damping structures are provided between the rotating plate II and both the rotating plate I and support II. A fixing component is provided between support I and support II. A lighting mechanism is provided on support II; It further includes a guide rod, a sliding plate, and a highly elastic spring. The right side of support I is connected to a guide rod. The sliding plate is slidably connected to the guide rod. The sliding plate is located below the pull rod. A highly elastic spring is connected between the sliding plate and support I.

[0007] Optionally, the fixing component includes a fixing rod I, a fixing block, a wedge block, and an elastic member I. A fixing rod I is connected to support I. The fixing block is slidably connected to the fixing rod I. The fixing block fits into the hole groove on support II. The fixing block is slidably connected to support I. A wedge block is connected to the front part of the fixing block. An elastic member I is connected between the fixing block and the fixing rod I.

[0008] Optionally, the lighting mechanism includes a mounting block I, an LED lamp, a mounting block II, and a photovoltaic panel. A mounting block I is connected to the rotating plate II. The LED lamp is slidably connected to the mounting block I. A mounting block II is connected to the rotating plate II. The photovoltaic panel is slidably connected to the mounting block II.

[0009] Optionally, the lighting mechanism further includes a fixing rod II and an elastic member II. A fixing rod II is inserted between the mounting block I and the photovoltaic panel. An elastic member II is connected between the fixing rod II and the mounting block I.

[0010] Optionally, it further includes a wedge plate. The front side of support I is connected to a wedge plate.

[0011] Optionally, it further includes a scraper. The scraper is slidably connected to support II. The upper side of the scraper is in contact with the lower side of the LED lamp.

[0012] Optionally, it further includes a storage box. The rear part of support I is connected to a storage box.

[0013] The present invention has the following advantages: 1. By installing a lifting mechanism in the present invention, the wedge block drives the fixed block to move rightward. At this time, the first elastic member will be compressed, and the fixed block will withdraw from the hole groove. The second bracket will descend due to the loss of the supporting force, and the components mounted on itself will also move downward together, thereby reducing the heights of the LED lamp and the photovoltaic panel, enabling maintenance personnel to perform maintenance operations without the aid of additional lifting equipment, greatly reducing the maintenance difficulty and cost, and ensuring the safety of the maintenance personnel.

[0014] 2. By installing a highly elastic spring in the present invention, when the pull rod contacts the sliding plate during the downward movement of the second bracket, the highly elastic spring will be compressed. Since the highly elastic spring has a relatively high elastic coefficient, when the pull rod drives the second bracket to move downward to the position of the sliding plate, the highly elastic spring can effectively absorb the impact force, enabling the second bracket to descend smoothly and avoiding collision with the first bracket caused by rapid descent, protecting the second bracket and the components mounted on itself from damage.

It is hereby declared that the orientation terms such as upper, lower, left, right, front, rear, inner and outer that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0026] Embodiment: A solar LED street lamp that is convenient for disassembly and maintenance, as Figure 1 、 Figure 3 and Figure 4 shown, includes Bracket I 1, Bracket II 101, Tie rod 102, Lifting mechanism 2, Fixing assembly and Lighting mechanism 3. The middle part of Bracket I 1 is slidably connected up and down with Bracket II 101. The lower right side of Bracket II 101 is connected with Tie rod 102. A hole groove 1011 is provided on the lower right side of Bracket I 1. A lifting mechanism 2 is provided on Bracket II 101. The lifting mechanism 2 includes Motor 21, Threaded rod 22, Connecting plate 23, Rotating plate I 24 and Rotating plate II 25. A motor 21 is installed on the rear side of Bracket II 101 through a fixing member. The output shaft of the motor 21 is connected with a threaded rod 22 through a coupling. A connecting plate 23 is threadedly connected to the threaded rod 22. A rotating plate I 24 is rotatably connected to the connecting plate 23. A friction damping structure is provided between the connecting plate 23 and the rotating plate I 24. The upper part of the rotating plate I 24 is rotatably connected with a rotating plate II 25. The other end of the rotating plate II 25 is rotatably connected with Bracket II 101. Friction damping structures are provided between the rotating plate II 25 and the rotating plate I 24 and Bracket II 101 respectively. Start the motor 21, and the output shaft of the motor 21 will drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, the connecting plate 23 threadedly connected thereto will move downward, thereby driving the rotating plate I 24 and the rotating plate II 25 to move downward together. During this process, the angle between the rotating plate I 24 and the rotating plate II 25 will gradually increase. A fixing assembly is provided between Bracket I 1 and Bracket II 101. A lighting mechanism 3 is provided on Bracket II 101.

[0027] As Figure 7As shown, the fixing component includes a fixing rod I 103, a fixing block 104, a wedge block 1041 and an elastic member I 105. A fixing rod I 103 is connected to the support I 1. A fixing block 104 is slidably connected to the fixing rod I 103. The fixing block 104 fits into the hole 1011 on the support II 101. The fixing block 104 is slidably connected to the support I 1. A wedge block 1041 is connected to the front of the fixing block 104. An elastic member I 105 is connected between the fixing block 104 and the fixing rod I 103.

[0028] As Figure 2 shown, it further includes a guide rod 107, a sliding plate 108 and a highly elastic spring 109. A guide rod 107 is connected to the right side of the support I 1. A sliding plate 108 is slidably connected to the guide rod 107. The sliding plate 108 is located below the pull rod 102. A highly elastic spring 109 is connected between the sliding plate 108 and the support I 1.

[0029] As Figure 5 and Figure 6 shown, the lighting mechanism 3 includes a mounting block I 31, an LED lamp 32, a mounting block II 33, a photovoltaic panel 34, a fixing rod II 35 and an elastic member II 36. A mounting block I 31 is connected to the rotating plate II 25. The LED lamp 32 is slidably connected up and down to the mounting block I 31. A mounting block II 33 is connected to the rotating plate II 25. The photovoltaic panel 34 is slidably connected back and forth to the mounting block II 33. A fixing rod II 35 for fixing the photovoltaic panel 34 is inserted between the mounting block I 31 and the photovoltaic panel 34. An elastic member II 36 is connected between the fixing rod II 35 and the mounting block I 31 through a spring seat. The connecting plate 23 will move down along the inclined surface of the wedge block 1041 and push the wedge block 1041 to the right. The wedge block 1041 will drive the fixing block 104 to move to the right. The fixing block 104 will withdraw from the hole 1011. The support II 101 will descend due to the loss of support force and drive the components mounted on itself to move down together, thereby reducing the heights of the LED lamp 32 and the photovoltaic panel 34, enabling maintenance personnel to perform maintenance operations without the need for additional lifting equipment, greatly reducing the maintenance difficulty and cost, and ensuring the safety of maintenance personnel.

[0030] As Figure 1 、 Figure 2 、 Figure 5 and Figure 9As shown, it also includes a wedge plate 106, a scraper 4 and a storage box 5. The front side of the bracket I1 is connected to the wedge plate 106, and the fixing rod II35 will contact the wedge plate 106 and continue to move downward along the inclined surface of the wedge plate 106. During this process, the fixing rod II35 will move to the right and disengage from the photovoltaic panel 34, so that the photovoltaic panel 34 is no longer constrained by the fixing rod II35. The maintenance personnel only need to move the photovoltaic panel 34 upward to dismantle it, thus reducing the steps of releasing the fixation of the photovoltaic panel 34; the bracket II101 is connected to the scraper 4 in a front-to-back sliding manner, and the upper side of the scraper 4 is in contact with the lower side of the LED lamp 32, so that the front-to-back sliding scraper 4 can scrape off the dust on the lower side of the LED lamp 32; the rear part of the bracket I1 is connected to the storage box 5, and the tools required for maintenance are placed in the storage box 5, and the storage box 5 is locked to prevent the tools from being lost, which can effectively reduce the burden on the maintenance personnel.

[0031] When using this device, the device should first be transported to the installation site using a hoisting device, and then firmly fixed to the ground at the installation site using fasteners. Tools required for maintenance should be placed into the storage box 5 and the storage box 5 should be locked to prevent the loss of tools, which can effectively reduce the burden on maintenance personnel. When it is necessary to repair the LED lamp 32 or the photovoltaic panel 34, start the motor 21. The output shaft of the motor 21 will drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, the connecting plate 23 threadedly connected thereto will move downward, thereby driving the rotating plate I 24 and the rotating plate II 25 to move downward together. During this process, the angle between the rotating plate I 24 and the rotating plate II 25 will gradually increase. When the connecting plate 23 contacts the inclined surface of the wedge block 1041, the connecting plate 23 will move downward along the inclined surface of the wedge block 1041 and push the wedge block 1041 to the right. The wedge block 1041 will drive the fixed block 104 to move to the right. At this time, the elastic member I 105 will be compressed, and the fixed block 104 will withdraw from the hole groove 1011. The support bracket II 101 will descend due to the loss of the supporting force and will drive the components mounted on itself to move downward together, thereby reducing the heights of the LED lamp 32 and the photovoltaic panel 34, enabling maintenance personnel to perform maintenance operations without the need to rely on additional lifting equipment, greatly reducing the maintenance difficulty and cost, and ensuring the safety of maintenance personnel. When the pull rod 102 contacts the sliding plate 108 during the downward movement of the support bracket II 101, the sliding plate 108 will be driven to move downward, and the highly elastic spring 109 will also be compressed accordingly. Since the highly elastic spring 109 has a relatively high elastic coefficient, when the pull rod 102 drives the support bracket II 101 to move downward to the position of the sliding plate 108, the highly elastic spring 109 can effectively absorb the impact force, enabling the support bracket II 101 to descend smoothly and avoiding damage caused by a rapid descent resulting in a collision with the support bracket I 1, protecting the support bracket II 101 and the components mounted on itself from being damaged. As the support bracket II 101 and the lighting mechanism 3 mounted on the support bracket II 101 move downward together, the fixed rod II 35 will contact the wedge-shaped plate 106 and continue to move downward along the inclined surface of the wedge-shaped plate 106. At this time, the elastic member II 36 will be stretched. During this process, the fixed rod II 35 will move to the right and disengage from the photovoltaic panel 34, enabling the photovoltaic panel 34 to no longer be restricted by the fixed rod II 35. Maintenance personnel only need to move the photovoltaic panel 34 upward to disassemble it, and then disassemble or repair the LED lamp 32. This reduces the steps of releasing the fixation of the photovoltaic panel 34, and the sliding installation method facilitates the disassembly of the photovoltaic panel 34 and the LED lamp 32, improving the maintenance efficiency. In addition, pulling the scraper 4 up and down can remove the dust on the cover of the LED lamp 32, thereby expanding the illumination range of the LED lamp 32 and enhancing the illumination intensity.When the reset device is required to complete the repair work, the pull rod 102 should be lifted upward to make the support II 101 and the components thereon rise together. As the pull rod 102 rises, the highly elastic spring 109 will push the slide plate 108 to gradually return to its original position. When the hole groove 1011 on the support II 101 is aligned with the fixed block 104, the elastic member I 105 will automatically rebound, causing the fixed block 104 to re-embed into the hole groove 1011, thereby fixing the position of the support II 101. At this time, start the motor 21 again, and the output shaft of the motor 21 will drive the threaded rod 22 to rotate in the reverse direction, causing the connecting plate 23 to move upward and reset, and finally driving the entire lighting mechanism 3 to reset.

[0032] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
