Description

Technical Field

[0002] With the development of society and the advancement of science and technology, human demand for energy is growing day by day, and solar energy, as a clean and renewable energy source, is widely used in various fields. In the field of lighting, solar street lights, as a green and environmentally friendly lighting method, have been widely used. The core components of solar street lights mainly include solar panels, batteries, LED lights, controllers and sensors. Among them, the controller plays a vital role as the intelligent management part of solar street lights. It can automatically adjust the output voltage and current of solar panels according to weather, time and other conditions, thereby ensuring the normal operation of street lights in different environments. The controller is generally made of microcomputer chips and equipped with a variety of sensors and communication interfaces, which provides users with a more convenient management and maintenance method. Through the controller, users can monitor the working status of street lights in real time, detect and handle faults in time, and greatly improve maintenance efficiency. Among the components of solar street lights, solar panels are the key components responsible for converting light energy into electrical energy. However, solar panels may encounter various damage situations during use. For example, since solar panels are usually installed in outdoor environments, they will inevitably be contaminated by dust, leaves and other debris.

DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0059] See also Figure 1-Figure 12The embodiment of the present invention provides a solar street lamp that is easy to repair and maintain, including a street lamp pillar 1, on which a street lamp pole 5 is fixedly mounted, and further comprising:

[0060] A multifunctional bracket 6, wherein the multifunctional bracket 6 is fixedly connected to the street light pillar 1, and a solar cell panel 8 is also arranged on the multifunctional bracket 6, and the solar cell panel 8 is detachably connected to the multifunctional bracket 6;

[0061] and a maintenance control mechanism, the maintenance control mechanism is respectively connected to the street lamp pillar 1, the multifunctional bracket 6 and the solar cell panel 8, wherein the maintenance control mechanism includes a pulling and lifting component and a guiding and positioning component;

[0062] The pulling and lifting components are respectively connected to the street lamp pillar 1, the multifunctional bracket 6 and the solar panel 8, and the guiding and positioning components are respectively connected to the multifunctional bracket 6 and the solar panel 8. The pulling and lifting components realize the combination and separation between the multifunctional bracket 6 and the guiding and positioning components on the solar panel 8 by pulling the solar panel 8 upward or downward.

[0063] During the use of the solar street light, the solar panel 8 on the multifunctional bracket 6 can supply power to the lamp beads on the end of the street light pole 5, so that the lamp beads on the street light pole 5 illuminate the road surface. The length of the street light pole 5 can be set according to actual needs, and the street light pole 5 and the solar panel 8 are respectively located on opposite sides of the street light pillar 1, so that the multifunctional bracket 6, the solar panel 8 and the maintenance control mechanism can be located on the back of the road. On the one hand, it can save space on the road and avoid affecting the various forms of vehicles on the road. On the other hand, it can minimize the damage to the multifunctional bracket 6, the solar panel 8 and the maintenance control mechanism by external factors such as passers-by, thereby ensuring the safety performance and service life of the equipment. No more details are given here. During the use of the street light, especially in some special areas (such as locations with more birds or areas with more dust), the surface of the multifunctional bracket 6 is easily dirty, thereby affecting the lighting efficiency. At this time, the surface of the multifunctional bracket 6 needs to be cleaned, and the lifting component is pulled by manpower to make the solar The solar panel 8 can be separated from the guide and positioning components on the multi-functional bracket 6, and the solar panel 8 can be slowly moved downward until it reaches the upper surface of the solar panel 8 for the staff to clean (the staff does not need to climb to a high place, thereby ensuring the safety of the staff during the entire cleaning process, and after the solar panel 8 reaches a lower position, the staff can use existing cleaning equipment to fully clean the upper surface of the solar panel 8, especially some stubborn stains, which is conducive to ensuring the cleaning effect). After cleaning, the solar panel 8 is pulled up again by manpower to move the solar panel 8 up and reach the surface of the multi-functional bracket 6. At this time, the multi-functional bracket 6 and the guide and positioning components on the solar panel 8 are combined under the action of tension, thereby ensuring the stability of the solar panel 8 during use. The structure is simple and the cost is low, and the staff can easily clean the obstructions on the multi-functional bracket 6, thereby improving the lighting efficiency, ensuring the lighting effect of the street lamp, and providing convenience for the staff.

[0064] In one embodiment of the present invention, see Figure 1-Figure 12 , the pulling and lifting assembly comprises:

[0065] A reel 29, the reel 29 is rotatably mounted in the street lamp support 1, and a plurality of reel baffles 30 are provided on the reel 29;

[0066] A driving wheel 2, wherein the driving wheel 2 is fixedly connected to one end of the winding shaft 29;

[0067] And a pull-up unit and a pull-down unit, wherein the pull-up unit and the pull-down unit are respectively connected to two ends of the solar cell panel 8 , and the pull-up unit and the pull-down unit are also connected to the winding shaft 29 .

[0068] It also includes: a positioning screw 10, one end of which is threadedly connected to the street lamp pillar 1 and is detachably connected to the driving wheel 2.

[0069] The pull-up unit comprises:

[0070] A directional pulley 11, wherein the number of the directional pulleys 11 is two, and the two directional pulleys 11 are both rotatably mounted on the multifunctional bracket 6;

[0071] A second sliding guide frame 9, wherein the second sliding guide frame 9 is fixedly connected to the street light pillar 1 and communicates with the street light pillar 1;

[0072] and a pull-up wire rope 7, one end of which is fixedly connected to the top of the solar panel 8, and the other end of which passes around the directional pulley 11, passes through the sliding guide frame 29, and then extends into the street lamp pillar 1 and is wound around the reel 29;

[0073] A buffer spring 31 is fixedly mounted on the pull-up wire rope 7 , and the buffer spring 31 is located inside the street lamp pillar 1 .

[0074] The pull-down unit comprises:

[0075] A sliding guide frame 3, wherein the sliding guide frame 3 is fixedly mounted on the street light pillar 1 and is connected to the street light pillar 1;

[0076] and a pull-down steel wire rope 4, one end of which is fixedly connected to the bottom end of the solar panel 8, and the other end of which passes through the sliding guide frame 3 and then extends into the street lamp pillar 1 and is wound around the reel 29;

[0077] The direction in which the pull-down steel wire rope 4 is wound around the winding shaft 29 is opposite to the direction in which the pull-up steel wire rope 7 is wound around the winding shaft 29 .

[0078] When the solar panel 8 needs to be cleaned, first, the positioning screw 10 is removed from the street lamp pillar 1 and the driving wheel 2. The driving part of the positioning screw 10 can adopt a special structure, such as a triangle, a pentagon, etc. The positioning screw 10 can only be removed by a corresponding special tool to prevent other non-staff from rotating the driving wheel 2 privately, thereby ensuring the safety of the equipment during use. In addition, the positioning screw 10 can also play a positioning role to prevent the driving wheel 2 from automatically rotating during use, thereby affecting the stability of the solar panel 8 on the multi-functional bracket 6. After the positioning screw 10 is removed, the driving wheel 2 is rotated by manpower to drive the winding shaft 29 to rotate counterclockwise (such as Fig.12As shown in the figure), the pull-down steel wire rope 4 can be gradually wound on the winding shaft 29, while the pull-up steel wire rope 7 wound on the winding shaft 29 is gradually loosened. The winding shaft 29 can be divided into multiple winding positions by multiple winding baffles 30 to avoid the entanglement of multiple ropes. In addition, by extending or contracting the buffer spring 31, the position state of the solar panel 8 changes (for example, when the solar panel 8 enters or leaves the multi-functional bracket 6, the angle of the solar panel 8 changes), so that the steel wire rope is tightened, thereby affecting the upward or downward movement of the solar panel 8. As the pull-down steel wire rope 4 is continuously wound on the winding shaft 29, the solar panel 8 can be moved downward, so that the multi-functional bracket 6 and the guide positioning assembly on the solar panel 8 are separated, and the solar panel 8 is slowly moved. The solar panel 8 is moved upward or downward to a position convenient for cleaning. In addition, during the movement of the rope, the upper pulley 7 is always clamped on the directional pulley 11, and since there are multiple ropes, it is possible to ensure that the solar panel 8 moves upward or downward in a certain placement state, thereby avoiding the solar panel 8 from tilting, thereby affecting the combination between the multi-functional bracket 6 and the solar panel 8. The structures of the sliding guide frame 1 3 and the sliding guide frame 2 9 are similar, both of which are hollow rod-shaped structures, and guide components such as balls or guide wheels are arranged inside the hollow to make the lower pulley 4 or the street light pole 5 slide in a certain direction. The above are all prior arts, similar to the form of a fixed pulley, which is simplified here. It mainly plays a guiding role for the rope. On the contrary, after the solar panel 8 is cleaned, the driving wheel 2 is rotated in the opposite direction to move the solar panel 8 upward and finally reach the multi-functional bracket 6 for fixation.

[0079] In one embodiment of the present invention, see Figure 1-Figure 12 , further comprising: a guide baffle 18, wherein the number of the guide baffles 18 is two, and the two guide baffles 18 are respectively fixedly mounted on both sides of the multifunctional bracket 6;

[0080] And a roller 19, wherein the number of the rollers 19 is plural, and the plural rollers 19 are rotatably connected to the two guide baffles 18 respectively.

[0081] In the process of the solar panel 8 reaching the multi-functional bracket 6, the guide baffle 18 and the roller 19 can play a guiding role and reduce the friction between the solar panel 8 and the multi-functional bracket 6, so that the solar panel 8 can smoothly enter the multi-functional bracket 6 or be separated from the multi-functional bracket 6.

[0082] In one embodiment of the present invention, see Figure 1-Figure 12 , the guiding and positioning component comprises:

[0083] Anti-slip columns 15, the number of the anti-slip columns 15 is two, and the two anti-slip columns 15 are fixedly mounted on the solar cell panel 8;

[0084] And the elastic card seat 14, the number of the elastic card seat 14 is also two, the two elastic card seats 14 are fixedly connected to the multi-functional bracket 6, and the two elastic card seats 14 are detachably connected to the two anti-slip columns 15 respectively.

[0085] The guiding and positioning assembly also includes:

[0086] A self-locking socket 17, wherein the self-locking socket 17 is fixedly connected to the top of the multi-functional bracket 6, and a U-shaped groove is provided on the self-locking socket 17;

[0087] An L-shaped positioning plug plate 23, one end of which is fixedly connected to the solar panel 8, and the other end of which is detachably connected to a U-shaped groove provided on the self-locking socket 17;

[0088] And a loosening control unit, which is connected to the solar panel 8, the self-locking socket 17 and the L-shaped positioning plug plate 23 respectively.

[0089] The release control unit comprises:

[0090] A self-locking controller 20, wherein the self-locking controller 20 is fixedly mounted on the self-locking socket 17, wherein the self-locking controller 20 is composed of a cylinder, a spring and a latch, one end of the latch is located in the cylinder and is slidably connected to the cylinder, and the two ends of the spring are fixedly connected to the cylinder and the latch respectively;

[0091] A through hole 21, which is provided on the self-locking socket 17 and the L-shaped positioning plug plate 23 and is arranged opposite to the latch on the self-locking controller 20;

[0092] A movable connecting plate 25, wherein the movable connecting plate 25 is located in a cavity provided on the solar cell panel 8 and is slidably connected to the cavity via a slider 24, and the slider 24 is fixedly connected to the pulling and lifting assembly;

[0093] A return spring 27, two ends of which are fixedly connected to the inner wall of the cavity on the solar cell panel 8 and the movable connecting plate 25 respectively;

[0094] and an adsorption portion 28 , wherein the adsorption portion 28 is located on the movable connecting plate 25 . Under normal working conditions, the adsorption portion 28 drives the latch to overcome the elastic force of the spring and be inserted into the through hole 21 .

[0095] See also Figure 1-Figure 12, further comprising: a flow gap 12, wherein the flow gap 12 is located on the bottom of the multifunctional bracket 6;

[0096] A component integrated box 13, wherein the component integrated box 13 is fixedly mounted on the solar panel 8, and an integrated power plug 22 is also fixedly mounted on the component integrated box 13;

[0097] And a circuit conducting support rod 16 , wherein the circuit conducting support rod 16 is fixedly connected to the street light pillar 1 and electrically connected to the street light pole 5 , and the circuit conducting support rod 16 is also detachably connected to the power connection integrated plug 22 .

[0098] After the solar panel 8 is cleaned, the upward pulling wire rope 7 will pull the solar panel 8 upward. When the solar panel 8 moves to the multi-functional bracket 6, as the solar panel 8 continues to move on the roller 19 on the multi-functional bracket 6, the anti-detachment column 15 can be brought into contact with the elastic holder 14, and under the action of the thrust, the elastic holder 14 can be elastically deformed, thereby enlarging the opening on the elastic holder 14, and finally making the anti-detachment column 15 snap into the larger grooved part on the elastic holder 14, and the opening part on the elastic holder 14 returns to its original shape, so that the anti-detachment column 15 can be limited to ensure the stability of the solar panel 8 on the multi-functional bracket 6, especially after the equipment fails and loses the pulling force on the solar panel 8 In addition, during the upward movement of the solar panel 8, the L-shaped positioning plate 23 can be inserted into the U-shaped groove on the self-locking socket 17, wherein the end of the L-shaped positioning plate 23 is a V-shaped structure or an inclined structure. When the L-shaped positioning plate 23 enters the U-shaped groove, since the end of the pin is also located in the U-shaped groove, when the end of the pin contacts the end of the L-shaped positioning plate 23, under the pushing action of the inclined surface, the pin can overcome the elastic force of the spring and extend into the cylinder for a distance until the through hole 21 opened on the L-shaped positioning plate 23 is opened. When aligned with the through hole 21 provided on the self-locking socket 17, the pin will be inserted into the through hole 21 on the L-shaped positioning plate 23 under the elastic force of the spring, thereby limiting the L-shaped positioning plate 23, further ensuring the stability of the solar panel 8 placed on the multi-functional bracket 6, and thus ensuring the safety performance of the equipment during use. Among them, a magnet is provided at the end of the pin, and it has the same magnetic pole as the adsorption portion 28 on the movable connecting plate 25. When the solar panel 8 reaches the specified position on the multi-functional bracket 6, the adsorption portion 28 in the cavity also just reaches the upper part of the self-locking controller 20. At this time, the adsorption portion 28 is closest to the magnet on the pin and is arranged opposite to it. At this time, under the action of the magnetic repulsion, the pin can overcome the elastic force of the spring and , and moves toward the through hole 21 on the L-shaped positioning plug plate 23, thereby forming an automatic locking function, wherein the mobile connecting plate 25 is detachably provided with an inspection cover 26, and the adsorption portion 28 can be replaced and repaired. In addition, the adsorption portion 28 can also be in the form of an electromagnet, which will not be described in detail here. When the solar panel 8 needs to be cleaned, under the pulling action of the pull-down wire rope 4, the slider 24 will first slide downward in the cavity, and drive the mobile connecting plate 25 and the adsorption portion 28 to move synchronously. At this time, the reset spring 27 is gradually in a compressed state. As the adsorption portion 28 gradually moves away from the self-locking controller 20, when the pin loses the effect of the magnetic repulsion, under the elastic action of the spring, the pin can move upward and separate from the through hole 21 on the L-shaped positioning plug plate 23.Thereby, the self-locking function between the self-locking socket 17 and the L-shaped positioning plug plate 23 is lost. Under the continuous pulling action of the pull-down wire rope 4, when the slider 24 reaches the bottom of the cavity, the slider 24 and the movable connecting plate 25 cannot continue to slide in the cavity. At this time, the solar panel 8 as a whole will move downward under the pulling force of the pull-down wire rope 4, so that the anti-detachment column 15 can be separated from the elastic holder 14. After the solar panel 8 completely loses its positioning function, it can be smoothly detached from the multifunctional bracket 6 and moved downward for cleaning.

[0099] In addition, since electrical components are more susceptible to damage than the solar panel 8, the power connection integrated plug 22 is provided to cooperate with the circuit conduction support rod 16. After the solar panel 8 reaches the multi-functional bracket 6, the power connection integrated plug 22 will be inserted into the circuit conduction support rod 16, thereby automatically energizing the entire circuit. When the solar panel 8 is separated from the multi-functional bracket 6, the power connection integrated plug 22 will also be separated from the circuit conduction support rod 16, so that the component integrated box 13 also reaches a position that is convenient for the staff to replace and repair, thereby ensuring the safety of the maintenance work and providing convenience for the staff. No further details will be given here.
