Description

Technical Field

[0001] The present invention belongs to the technical field of LED street lamps, and in particular relates to an LED street lamp with a self-cleaning function. Background Art

[0002] Street lights are the main facilities for urban lighting and play an important role in nighttime lighting in cities. Traditional street lights often use high-pressure sodium lamps for 360-degree lighting, and the disadvantage of large light loss causes a huge waste of energy. LED street lights have gradually entered people's field of vision with their advantages of directional lighting, low power consumption, good driving characteristics, fast response speed, high earthquake resistance, long service life and green environmental protection, and have become the world's new generation of energy-saving light sources with the most advantages in replacing traditional light sources. Therefore, LED street lights have become the best choice for energy-saving transformation of road lighting.

[0003] The existing LED street lamp with self-cleaning function can drive the cleaning roller to move upward along the inclined surface of the lamp board and clean the surface through the mutual cooperation between the telescopic slot, auxiliary slot, vertical rod, cleaning roller, axle, second spring, moving rod, moving ring, auxiliary block, first spring, groove, support shaft and rotating ring. After cleaning, the moving ring is released, and the second spring contracts and drives the moving ring to move downward and reset through the moving rod. Then the first spring also contracts and drives the vertical rod to reset, so that the cleaning roller moves downward and resets.

[0004] Although the existing street lamps can realize the self-cleaning function, when the cleaning roller reciprocates to clean the lamp board, the cleaning roller moving upward can clean the impurities on the lamp board, but when the cleaning roller moves downward, its rotation direction is opposite to the direction when it moves upward. This will cause the cleaned impurities to stick to the lamp board again, resulting in poor cleaning efficiency of the lamp board, and then resulting in poor lighting effect of the street lamp. In addition, during the reciprocating cleaning process of the existing street lamp, its own electric parts need to change the working direction in time to realize the reciprocating work of the cleaning roller. This repeated changing of the working direction will affect its own service life to a certain extent, and then increase the maintenance cost of the street lamp.

[0005] Therefore, in view of the above situation, there is an urgent need to develop an LED street lamp with a self-cleaning function to overcome the shortcomings in current practical applications. Summary of the invention

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0054] like Figures 1 to 9 As shown, an LED street lamp with a self-cleaning function provided as an embodiment of the present invention includes a lamp post 1, a lamp body structure 2 and a solar mounting frame 3. The bottom of the lamp post 1 is fixed on a concrete pile foundation, and the two ends of the top of the lamp post 1 are respectively fixed with the lamp body structure 2 and the solar mounting frame 3. The solar mounting frame 3 is provided with solar panels 4. The lamp body structure 2 is composed of a lamp board 21, an outer shell 22, a lampshade 5 and an LED lamp. The lampshade 5 is buckled in the middle of the lamp board 21, and an LED lamp is installed inside the lampshade 5. One side of the lampshade 5 extends to the outside of the lamp board 21, and the lamp board 21 is connected to the outer shell 22 as a whole by screws. The outer shell 22 can prevent rainwater or impurities from the outside from entering the interior of the lamp board 21. The lamp board 21 is provided with guide grooves 23 for the guide frame 6 to slide on both sides around the lampshade 5, and one end of the lamp board 21 is also provided with a slide groove 24 and a heat dissipation hole 25. One end of the guide frame 6 extends to the inner side of the lamp board 21, and the opening direction of the slide groove 24 is parallel to the moving direction of the guide frame 6. It also includes:

[0055] A reciprocating drive control structure 9, which is installed on the inner side of the lamp board 21, and includes a drive control component 91, a screw rod 92, a connecting component 93 and an adjusting component 94, wherein the screw rod 92 is movably installed on the inner side of the lamp board 21;

[0056] The drive control assembly 91 includes a connecting member 917 and two rotating cylinders 914. The two rotating cylinders 914 rotate in opposite directions. The two rotating cylinders 914 are respectively arranged on both sides of the connecting member 917, and the two rotating cylinders 914 are rotatably arranged on the inner side of the lamp board 21. The connecting member 917 is fixed to one end of the screw rod 92, and the two sides of the connecting member 917 are intermittently slidably matched with the tapered grooves 916 opened on one side of the two rotating cylinders 914.

[0057] The connecting assembly 93 includes a moving member 931, a guide shaft 932 and a spring B933. One end of the moving member 931 is slidably mounted on the guide shaft 932. The middle part of the moving member 931 is threadedly engaged with the screw rod 92. The other end of the moving member 931 is fixedly connected to one end of the guide frame 6. The guide shaft 932 is parallel to the screw rod 92 and fixed to the inner side of the lamp board 21. Both ends of the guide shaft 932 are installed with springs B933 that intermittently contact the moving member 931.

[0058] The adjustment assembly 94 includes a connecting tube 941, an adjusting tube 942 and a sliding member 944. The connecting tube 941 is fixed to the other end of the screw rod 92. The adjusting tube 942 is fixed to the outer wall of the connecting tube 941. Both ends of the outer wall of the adjusting tube 942 are provided with annular limiting grooves 943. The two annular limiting grooves 943 intermittently slide with the sliding member 944 vertically slidably mounted on the inner side of the light board 21.

[0059] Without changing the rotation direction of the two rotating cylinders 914, the two rotating cylinders 914 can reciprocately change the rotation direction of the screw 92 through the moving member 931, the spring B933, the sliding member 944 and the adjusting cylinder 942. The screw 92 can drive the guide frame 6 to reciprocate by reciprocatingly changing the rotation direction.

[0060] A cleaning structure 7, wherein the cleaning structure 7 is rotatably mounted on a guide frame 6 located outside the lamp panel 21, and cleaning brushes and cleaning cloth that contact the outer surface of the lampshade 5 are sequentially mounted on both sides of the cleaning structure 7, and one end of the cleaning structure 7 is connected to a reversing structure 8 installed in a slide groove 24, and the guide frame 6 drives the cleaning structure 7 to move back and forth. The reversing structure 8 can drive the cleaning structure 7 to rotate 180 degrees before changing the moving direction by cooperating with the guide frame 6, so that under the same moving direction, the cleaning brush on the cleaning structure 7 is always located in front of the cleaning cloth, thereby achieving continuous and sufficient cleaning of the outer surface of the lampshade 5.

[0061] In this embodiment, when the sliding member 944 limits the screw 92 by cooperating with an annular limiting groove 943, the connecting member 917 slides with the conical groove 916 on a rotating cylinder 914, and the rotating cylinder 914 drives the screw 92 to rotate through the connecting member 917, and the screw 92 drives the moving member 931 to slide on the guide shaft 932, and the moving member 931 drives the guide frame 6 to move, and the guide frame 6 drives the cleaning structure 7 to move, and the cleaning structure 7 drives the cleaning brush and the cleaning cloth thereon to clean the outer surface of the lampshade 5, so as to realize the self-cleaning function of the street lamp, ensure the light transmittance of the lampshade 5, and improve the lighting effect of the street lamp. Through automatic cleaning, the need for manual cleaning is reduced, especially for high places or dangerous areas that are difficult to reach manually. The automatic cleaning function significantly reduces the maintenance cost, reduces the risk of manual climbing and operation, improves the safety of the staff, and can be cleaned regularly and effectively to reduce the accumulation of dirt and impurities on the lampshade 5, delay the aging and damage of the lampshade 5 and the lighting equipment, and extend the service life of the street lamp;

[0062] When the moving member 931 moves to conflict with a spring B933, the spring B933 cooperates with the guide shaft 932 to slow down the moving speed of the moving member 931. At this time, the moving member 931 will be subject to resistance in the opposite direction of its moving direction. At the same time, the moving member 931 will also transfer the resistance to the screw rod 92 and the adjustment cylinder 942. At this time, the adjustment cylinder 942 will apply a thrust to the sliding member 944 in the opposite direction of the moving direction of the moving member 931.

[0063] When the resistance of the screw 92 reaches a certain level, the adjusting cylinder 942 pushes the sliding member 944 out of an annular limiting groove 943 and makes it slide and cooperate with another annular limiting groove 943. At the same time, the adjusting cylinder 942 drives the screw 92 to move through the connecting cylinder 941. The screw 92 drives the connecting member 917 to separate from one rotating cylinder 914 and slide and cooperate with the conical groove 916 on the other rotating cylinder 914. The other rotating cylinder 914 drives the screw 92 to rotate in the opposite direction through the connecting member 917. The screw 92 drives the moving member 931 to move in the opposite direction, so that the moving member 931 slowly separates from one spring B933 and moves in the direction of the other spring B933. At this time, the sliding member 944 can resume the limitation and fixation of the screw 92 by cooperating with another annular limiting groove 943.

[0064] Driven by the two rotating cylinders 914 in different rotation directions, the screw 92 can stably drive the moving part 931 to move back and forth, and the moving part 931 drives the guide frame 6 to move back and forth. The guide frame 6 can drive the cleaning structure 7 to move back and forth, so that it can realize continuous cleaning of the outer surface of the lampshade 5, ensure the light transmittance of the lampshade 5, and improve the lighting effect of the street lamp. Before the guide frame 6 drives the cleaning structure 7 to move and change its moving direction, the reversing structure 8 can drive the cleaning structure 7 to rotate 180 degrees, so that under the same moving direction, the cleaning brush on the cleaning structure 7 is always located in front of the cleaning cloth, effectively cleaning the impurities on the outer surface of the lampshade 5, and fully cleaning it with the cleaning cloth, further ensuring the light transmittance of the lampshade 5, which not only improves the lighting efficiency and service life of the street lamp, but also improves the operating efficiency, enhances environmental adaptability, and optimizes energy utilization, providing an effective solution for the modernization and maintenance of urban infrastructure.

[0065] In a preferred embodiment, the moving member 931 preferably adopts a straight-line block structure.

[0066] like Figures 3 to 9 As shown, as a preferred embodiment of the present invention, the drive control component 91 also includes a motor 911, a main bevel gear 912, a secondary bevel gear 913 and a bracket 915. The motor 911 is fixed on the inner side of the lamp board 21. The main bevel gear 912 is fixed on the output end of the motor 911. Both sides of the main bevel gear 912 are meshed with secondary bevel gears 913. The two secondary bevel gears 913 are respectively fixed on the outer walls of two rotating cylinders 914. The two rotating cylinders 914 are rotatably mounted on the inner side of the lamp board 21 through the bracket 915.

[0067] like Figures 3 to 9 As shown, as a preferred embodiment of the present invention, the secondary bevel gear 913, the rotating cylinder 914, the conical groove 916, the connecting piece 917 and the screw 92 are all concentric, the connecting piece 917 preferably adopts a circular block structure, and both sides of the connecting piece 917 are designed to be conical surfaces that slide with the conical groove 916, and a through hole is opened in the middle of the rotating cylinder 914 for the screw 92 to pass through.

[0068] In this embodiment, the motor 911 drives the main bevel gear 912 to rotate, and the main bevel gear 912 simultaneously drives the two sub-bevel gears 913 to rotate and ensure that the rotation directions of the two are opposite, and the two sub-bevel gears 913 simultaneously drive their respective rotating cylinders 914 to rotate, so that the rotation directions of the two rotating cylinders 914 are opposite, so that the two rotating cylinders 914 can drive the screw 92 to rotate reciprocatingly by intermittently cooperating with the connecting piece 917, and then reciprocately change the moving direction of the guide frame 6, so that the cleaning structure 7 can continuously and fully clean the outer surface of the lampshade 5 to ensure its light transmittance and improve the lighting effect of the street lamp. Through automatic cleaning, the need for manual cleaning is reduced, especially for high places or dangerous areas that are difficult to reach manually. The automatic cleaning function significantly reduces the maintenance cost, reduces the risk of manual climbing and operation, improves the safety of the staff, and can regularly and effectively clean and reduce the accumulation of dirt and impurities on the lampshade 5, delays the aging and damage of the lampshade 5 and lighting equipment, and extends the service life of the street lamp.

[0069] like Figures 3 to 9 As shown, as a preferred embodiment of the present invention, the adjustment component 94 also includes a mounting cylinder 945 and a spring C946. The mounting cylinder 945 is fixed on the inner side of the lamp board 21. A sliding member 944 is vertically slidably installed in the mounting cylinder 945.

The other end of the sliding member 944 is connected to the inner wall of the mounting cylinder 945 through the spring C946.

[0070] In this embodiment, the spring C946 drives the sliding member 944 to move toward the direction close to the annular limiting groove 943 through its own elastic force, so that the sliding member 944 can effectively slide with the annular limiting groove 943, thereby effectively limiting the screw rod 92, ensuring the movement stability of the moving member 931 and the guide frame 6;

[0071] When the adjusting cylinder 942 pushes the sliding member 944 out of an annular limit groove 943, the sliding member 944 moves toward the inside of the mounting cylinder 945, thereby squeezing the spring C946. When the sliding member 944 is separated from an annular limit groove 943, the spring C946 drives the sliding member 944 to always fit with the outer wall of the adjusting cylinder 942 through its own elastic force. When another annular limit groove 943 on the adjusting cylinder 942 moves to a position matching with the sliding member 944, the spring C946 drives the sliding member 944 to move toward the other annular limit groove 943 through its own elastic force, so that the sliding member 944 slides and fits with the other annular limit groove 943, and restores the limiting of the screw 92, thereby ensuring the movement stability of the moving member 931 and the guide frame 6 again, so that the cleaning structure 7 can stably and effectively clean the outer surface of the lampshade 5.

[0072] In a preferred embodiment, the sliding member 944 preferably adopts a sliding structure composed of a strip rod and a ball, the ball is slidably matched with the annular limiting groove 943, and the two sides of the annular limiting groove 943 are set as inclined surfaces, so that not only the ball can effectively slide with the annular limiting groove 943, but also the adjustment cylinder 942 can be convenient for pushing the ball, thereby facilitating the intermittent sliding cooperation between the ball and the two annular limiting grooves 943;

[0073] The connecting tube 941 and the adjusting tube 942 are preferably of a circular cylindrical structure, and the connecting tube 941 and the adjusting tube 942 are concentric with the screw rod 92 .

[0074] like Figure 3 , Figure 4 , Figure 7 and Fig.10 As a preferred embodiment of the present invention, the cleaning structure 7 includes a main mounting plate 71, a mounting shaft 72, a sub-mounting plate 73, a spring A74, a hinge seat 75 and a mounting cross plate 76. The middle part of the main mounting plate 71 is rotatably mounted on the middle part of the guide frame 6 through the mounting shaft 72. One end of the mounting shaft 72 is connected to the reversing structure 8. Sub-mounting plates 73 are vertically slidably mounted on both sides of the main mounting plate 71. The two sub-mounting plates 73 are located on both sides of the guide frame 6, and one side of the two sub-mounting plates 73 is movably connected to the main mounting plate 71 through the spring A74. The other sides of the two sub-mounting plates 73 are distributed with hinge seats 75. Two mounting cross plates 76 are provided. The two mounting cross plates 76 are mounted on the two sub-mounting plates 73 through the hinge seats 75. Cleaning brushes and cleaning cloths are respectively mounted on the two mounting cross plates 76.

[0075] like Figure 3 , Figure 4 , Figure 7 and Fig.10 As a preferred embodiment of the present invention, the articulated seat 75 preferably adopts a unidirectional rotating articulated seat 75, and the articulated seat 75 can drive the mounting cross plate 76 to deflect in the direction away from the guide frame 6, and the articulated seat 75 is equipped with a spring clip that can drive the mounting cross plate 76 to quickly reset, so that the cleaning brush and the cleaning cloth can fit the outer surface of the lampshade 5 again after changing direction.

[0076] In this embodiment, the spring A74 can drive the cleaning brushes and the cleaning cloth on the two mounting horizontal plates 76 to effectively and fully fit the outer surface of the lampshade 5 through its own elastic force, so that the cleaning brushes and the cleaning cloth can effectively and fully clean the outer surface of the lampshade 5;

[0077] When the guide frame 6 drives the main mounting plate 71 to move back and forth, the main mounting plate 71 moves back and forth through the auxiliary mounting plate 73, the hinge seat 75 and the mounting cross plate 76. When the reversing structure 8 drives the main mounting plate 71 to rotate 180 degrees through the mounting shaft 72, the main mounting plate 71 drives the auxiliary mounting plate 73 to rotate, and the auxiliary mounting plate 73 rotates through the hinge seat 75 and the mounting cross plate 76. The mounting cross plate 76 drives the cleaning brush and the cleaning cloth to rotate. The cleaning brush and the cleaning cloth will inevitably collide with the guide frame 6 during the rotation process. At this time, the hinge seat 75 can drive the mounting cross plate 76 to deflect. , so that the cleaning brush and the cleaning cloth are deflected and pass smoothly through the guide frame 6, thereby realizing effective reversal of the cleaning brush and the cleaning cloth, so that under the same moving direction, the cleaning brush on the cleaning structure 7 is always located in front of the cleaning cloth, effectively cleaning the impurities on the outer surface of the lampshade 5, and fully cleaning it with the cleaning cloth, further ensuring the light transmittance of the lampshade 5, not only improving the lighting efficiency and service life of the street lamp, but also improving the operating efficiency, enhancing environmental adaptability, and optimizing energy utilization, providing an effective solution for the modernization and maintenance of urban infrastructure.

[0078] In a preferred embodiment, the outer shape of the mounting cross plate 76 can be contoured to the outer surface of the lampshade 5, so that the cleaning brush and cleaning cloth thereon can effectively and fully fit with the outer surface of the lampshade 5, further improving the cleaning quality and cleaning efficiency of the lampshade 5, thereby improving the lighting efficiency of the street lamp.

[0079] like Figure 3 and Fig.10 As shown, as a preferred embodiment of the present invention, the reversing structure 8 includes a transmission member 81, a rotating shaft 82, a spur gear 83 and a rack 84, one end of the transmission member 81 is fixed on the mounting shaft 72, the other end of the transmission member 81 is fixed on the rotating shaft 82, the rotating shaft 82 is rotatably mounted on the slider, the slider is slidably mounted on the slide groove 24, a spur gear 83 is fixed on the rotating shaft 82, the spur gear 83 is intermittently meshed with two racks 84 distributed at both ends of the slide groove 24, the two racks 84 are fixed on the outside of the light board 21, and the design direction of the two racks 84 is parallel to the opening direction of the slide groove 24.

[0080] In this embodiment, the installation shaft 72 drives the rotating shaft 82 to move synchronously through the transmission member 81, and the rotating shaft 82 drives the slider to slide in the slide groove 24, and at the same time, drives the spur gear 83 to move;

[0081] Before the moving part 931 is about to contact the spring B933, the spur gear 83 moves to a position meshing with the rack 84, and the rack 84 drives the rotating shaft 82 to rotate 180 degrees through the spur gear 83, and the rotating shaft 82 drives the transmission part 81 to rotate 180 degrees, and the transmission part 81 drives the installation shaft 72 to rotate 180 degrees, and the installation shaft 72 drives the main installation plate 71 to rotate 180 degrees, thereby realizing effective reversal of the cleaning brush and the cleaning cloth, so that in the same moving direction, the cleaning brush on the cleaning structure 7 is always located in front of the cleaning cloth, effectively cleaning the impurities on the outer surface of the lampshade 5, and fully cleaning it with the cleaning cloth, further ensuring the light transmittance of the lampshade 5, and improving the lighting efficiency and service life of the street lamp.

[0082] In a preferred embodiment, the transmission member 81 preferably adopts a transmission structure composed of a pulley and a belt. The installation shaft 72 will have a certain resistance when rotating. Only when the transmission member 81 rotates normally can it effectively drive the installation shaft 72 to rotate normally.

[0083] like Figure 3 and Fig.10 As shown, as a preferred embodiment of the present invention, the spur gear 83 and the two racks 84 are made of a plastic with good wear resistance or a metal material with good corrosion resistance, so as to ensure that the spur gear 83 and the two racks 84 exposed to the outside can work effectively and continuously, thereby extending the service life of the reversing structure 8, and the two racks 84 can be distributed on the same side of the spur gear 83, or on both sides of the spur gear 83, and both can drive the mounting shaft 72 to rotate 180 degrees, thereby driving the cleaning cloth and the cleaning brush to rotate 180 degrees.

[0084] The working principle of the present invention is:

[0085] The motor 911 drives the main bevel gear 912 to rotate, and the main bevel gear 912 drives the two auxiliary bevel gears 913 to rotate at the same time and ensures that the two rotation directions are opposite, and the two auxiliary bevel gears 913 drive their respective rotating cylinders 914 to rotate at the same time, so that the two rotating cylinders 914 rotate in opposite directions;

[0086] The spring C946 drives the sliding member 944 to move toward the direction close to the annular limiting groove 943 through its own elastic force, so that the sliding member 944 can effectively slide with the annular limiting groove 943, thereby effectively limiting the screw rod 92, ensuring the movement stability of the moving member 931 and the guide frame 6;

[0087] When the connecting member 917 is slidably matched with the tapered groove 916 on a rotating cylinder 914, the rotating cylinder 914 drives the screw 92 to rotate through the connecting member 917, the screw 92 drives the moving member 931 to slide on the guide shaft 932, and the moving member 931 drives the guide frame 6 to move;

[0088] When the moving member 931 moves to conflict with a spring B933, the spring B933 cooperates with the guide shaft 932 to slow down the moving speed of the moving member 931. At this time, the moving member 931 will be subject to resistance in the opposite direction of its moving direction. At the same time, the moving member 931 will also transfer the resistance to the screw rod 92 and the adjustment cylinder 942. At this time, the adjustment cylinder 942 will apply a thrust to the sliding member 944 in the opposite direction of the moving direction of the moving member 931.

[0089] When the resistance of the screw 92 reaches a certain level, the adjusting cylinder 942 pushes the sliding member 944 out of an annular limiting groove 943 and makes it slide and cooperate with another annular limiting groove 943. At the same time, the adjusting cylinder 942 drives the screw 92 to move through the connecting cylinder 941. The screw 92 drives the connecting member 917 to separate from one rotating cylinder 914 and slide and cooperate with the conical groove 916 on the other rotating cylinder 914. The other rotating cylinder 914 drives the screw 92 to rotate in the opposite direction through the connecting member 917. The screw 92 drives the moving member 931 to move in the opposite direction, so that the moving member 931 slowly separates from one spring B933 and moves in the direction of the other spring B933. At this time, the sliding member 944 can resume the limitation and fixation of the screw 92 by cooperating with another annular limiting groove 943.

[0090] Driven by the two rotating cylinders 914 in different rotation directions, the screw 92 can stably drive the moving member 931 to reciprocate, the moving member 931 drives the guide frame 6 to reciprocate, and the guide frame 6 can drive the cleaning structure 7 to reciprocate, so that it can realize continuous cleaning of the outer surface of the lampshade 5;

[0091] Before the moving member 931 is about to contact the spring B933, the spur gear 83 moves to a position meshing with the rack 84, the rack 84 drives the rotating shaft 82 to rotate 180 degrees through the spur gear 83, the rotating shaft 82 drives the transmission member 81 to rotate 180 degrees, the transmission member 81 drives the installation shaft 72 to rotate 180 degrees, and the installation shaft 72 drives the main installation plate 71 to rotate 180 degrees, thereby realizing effective reversal of the cleaning brush and the cleaning cloth, so that under the same moving direction, the cleaning brush on the cleaning structure 7 is always located in front of the cleaning cloth, effectively cleaning the impurities on the outer surface of the lampshade 5, and fully cleaning it with the cleaning cloth;

[0092] The above is the working principle of the LED street light with self-cleaning function.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
