Description

Technical Field

[0001] The present invention relates to the technical field of outdoor lighting equipment, and specifically to an LED street lamp with a dust-proof function. Background Art

[0002] In modern urban lighting systems, LED street lamps with dust-proof functions are crucial outdoor lighting equipment, providing stable and efficient lighting services in outdoor places such as roads and squares, ensuring the safe passage of pedestrians and vehicles at night or in low-light environments. Through specially designed dust-proof structures, such as sealed lamp covers and dust-proof filters, dust entering the interior of the lamp is effectively reduced, ensuring the normal operation of LED lamp beads and other electronic components, and maintaining a good lighting effect.

[0003] After long-term use of existing street lamps, dust covers the surface of the lamp body, which will hinder the propagation of light, reducing the amount of light actually projected onto the road surface, lowering the road lighting brightness, affecting the visual recognition of pedestrians and vehicles, and increasing the risk of night travel. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an LED street lamp with a dust-proof function, solving the problem that the lighting effect is affected by dust covering the surface of the lamp body.

An elevating assembly is arranged inside the connecting piece. A rotating assembly is arranged on the front side of the connecting piece. A rotating plate is arranged on the front side of the rotating assembly. The connecting piece is rotatably connected to the rotating plate. A fixed box is fixedly connected to the front side of the rotating plate. A plurality of lamp boards are fixedly connected to the bottom of the fixed box. Heat dissipation fins are fixedly connected to the bottom inner wall of the fixed box. An air pump is fixedly connected to the front side of the rotating plate. The input end of the air pump is fixedly connected to the fixed box. An air delivery pipe is fixedly arranged at the output end of the air pump. A cleaning assembly is arranged on the top of the fixed box.

[0006] By adopting the above technical solutions, it is realized that the connecting piece is driven by the elevating assembly to move up and down on the vertical pole, eliminating the need for workers to climb heights, improving the maintenance efficiency and safety; the flexible adjustment of the lighting angle is realized through the rotating assembly to meet the lighting requirements of different scenarios; the air pump pumps out the gas in the fixed box to accelerate the air flow, enhancing the heat dissipation effect of the lamp board and the heat dissipation fins; the cleaning assembly uses the gas output by the air pump to clean the lamp board and the solar panel, combined with the dust-proof net to block dust from entering, maintaining a good working state.

[0007] Preferably, the cleaning component includes a third motor fixedly connected between the fixed box. A reciprocating screw rod is fixedly arranged at the output end of the third motor. A sliding frame is threadedly connected to the surface of the reciprocating screw rod. A brush is fixedly connected inside the sliding frame, and the upper surface of the brush is in close contact with the lower surfaces of a plurality of lamp boards.

[0008] Preferably, two second gears are rotatably connected to the front side inside the sliding frame. A cleaning roller is fixedly connected to the front end of the upper second gear, and the two second gears are meshed with each other.

[0009] Preferably, a second rack is fixedly connected to the top of the fixed box, and the second rack is meshed with the lower second gear.

[0010] Preferably, the lifting component includes a first motor fixedly connected between the inner wall of the connecting member. A worm is fixedly arranged at the output end of the first motor. A worm gear is meshed with the front side of the worm. A first gear is fixedly connected to the left end of the worm gear, and both the worm gear and the first gear are rotatably connected to the connecting member.

[0011] Preferably, a vertical rod is slidably connected inside the connecting member. A first rack is fixedly connected to the rear side of the vertical rod. The first rack is meshed with the first gear. A base is fixedly connected to the bottom of the vertical rod.

[0012] Preferably, the rotating component includes a second motor fixedly connected to the connecting member. A threaded rod is fixedly arranged at the output end of the second motor. A moving block is threadedly connected to the surface of the threaded rod. Rotating rods are rotatably connected to both the left and right sides of the moving block, and the bottom ends of both rotating rods are rotatably connected to a rotating plate.

[0013] Preferably, a solar panel is fixedly connected to the top of the fixed box, and a dust-proof net is fixedly connected to the front side of the fixed box.

[0014] Preferably, a sliding rod is fixedly connected to the top of the fixed box, and the sliding rod is slidably connected to the sliding frame.

[0015] Preferably, an air delivery pipe is fixedly connected to the sliding frame, and a plurality of air jet nozzles are fixedly connected to the surface of the air delivery pipe.

[0016] Working principle: Start the first motor to drive the worm to rotate, driving the worm gear and the first gear to rotate. Since the first rack and the first gear are meshed with each other, the rotation of the first gear causes the connecting member to slide up and down along the vertical rod, facilitating the staff to lower the connecting member without the need for the staff to climb a ladder to a high place for maintenance;

[0017] When it is necessary to adjust the lighting angle of the street lamp, the second motor is turned on to drive the threaded rod to rotate, thereby driving the moving block to move. The rotating rod moves along with the moving block, driving the rotating plate to rotate around the connecting piece, so as to realize the adjustment of the lighting angles of components such as the rotating plate, the fixed box and the lamp panel to meet different lighting requirements;

[0018] The air pump is started to extract the gas inside the fixed box. The air in the fixed box accelerates to flow, improving the heat dissipation effect of the lamp panel and the heat dissipation fins. At the same time, a plurality of air nozzles are fixed on the surface of the air delivery pipe. When the sliding frame moves, it drives the air nozzles to move, expanding the range of air blowing and cleaning, so as to blow off the dust and sundries on the surfaces of the lamp panel and the solar panel;

[0019] The third motor drives the reciprocating lead screw to rotate. At this time, the sliding frame makes a reciprocating motion along the reciprocating lead screw. The brush moves along with the sliding frame to wipe and clean the lower surface of the lamp panel, removing the dust and impurities on the surface of the lamp panel. During the movement of the sliding frame, since the second gear at the bottom meshes with the second rack, the second rack will drive the second gear at the bottom to rotate, and the second gear at the bottom drives the second gear at the top to rotate in the reverse direction. The cleaning roller will rotate along with the rotation of the second gear, so as to realize the cleaning of the surface of the solar panel.

[0020] The present invention provides an LED street lamp with a dust-proof function. It has the following beneficial effects:

[0021] 1. In the present invention, the gas inside the fixed box is extracted by the air pump, conveyed to the air nozzles through the air delivery pipe, and then blown to the lamp panel and the solar panel by the air nozzles to blow off the dust and sundries on their surfaces. While cleaning the lamp panel and the solar panel, the air pump is used to extract the gas inside the fixed box, accelerating the air flow inside the fixed box and improving the heat dissipation effect of the lamp panel and the heat dissipation fins.

[0022] 2. In the present invention, the third motor drives the reciprocating lead screw to rotate, thereby driving the sliding frame to slide on the surface of the sliding rod. While the sliding frame is moving, the brush at the bottom cleans the lamp panel. At the same time, since the second gear at the bottom meshes with the second rack, when the sliding frame moves, it drives the two second gears to rotate, thereby driving the cleaning roller to rotate to clean the solar panel, realizing secondary cleaning again after the surface dust is blown off by the air nozzles to prevent dust from affecting the lighting and daylighting effects.

[0023] 3. In the present invention, the first motor drives the worm to rotate, thereby driving the worm wheel and the first gear to rotate. Since the first gear meshes with the first rack, it realizes driving the connecting piece to slide on the vertical rod, and realizes lowering the whole for maintenance when it is necessary to overhaul and maintain the lamp body, solving the problem that when the existing lamp body needs to be overhauled, the staff needs to set up a ladder, which affects the work efficiency.

[0024] 4. The present invention drives the threaded rod to rotate through the second motor. When the threaded rod rotates, it drives the moving block to move, thereby driving the rotating rod to move. The rotating rod jacks up the rotating plate and the fixed box, thereby realizing the adjustment of the irradiation angle of the lamp board to meet the diverse requirements of different road conditions and environments for the lighting angle.
