An adjustable solar street light

Abstract

This invention discloses an adjustable solar street light, belonging to the field of solar street light technology. It includes a base, on which a pole is fixedly mounted. A mounting block is fixedly mounted at the top of the pole, and mounting frames are symmetrically mounted on the mounting blocks. Solar panels are fixedly mounted on the mounting frames. This design utilizes the cooperation between the vertical pole and the lamp housing. In the early morning, a motor drives a spiral groove to rotate via a transmission rod, causing a protrusion to push the lamp housing upwards via a sliding plate and a linkage block, thus raising the overall height of the lamp body. Simultaneously, the lamp housing deflects under the pushing action of the vertical pole during the ascent, adjusting the lamp's illumination angle and expanding the lighting range to meet the basic lighting needs of roads in the early morning. In the evening, when all streetlights are turned on, the lamp body returns to its original position, lowering its height and adjusting its angle to concentrate the lighting intensity, precisely covering the road and sidewalk, avoiding wasted lighting, and improving the safety of pedestrians and vehicles.

Description

Technical Field

[0001] This invention relates to the field of solar street light technology, and more specifically, to an adjustable solar street light. Background Technology

[0002] A solar street light is a street lighting system that uses solar energy for charging and power. It typically consists of solar panels, batteries, a controller, and LED lights. The working principle of a solar street light is as follows: the solar panels absorb sunlight during the day and convert it into electrical energy, which is then stored in the batteries. At night or when there is insufficient light, the controller automatically senses this and activates the LED lights, using the stored electrical energy for illumination.

[0003] Most existing solar streetlights are fixedly installed on both sides of the road using poles, making it impossible to adjust the lighting angle. However, lighting needs often change in actual use: before dawn, pedestrian and vehicular traffic is high, requiring ample lighting to reduce safety hazards; after dawn, as most people sleep, pedestrian and vehicular traffic is sparse, and some streetlights are usually turned off to minimize resource waste, but a few still need to be on to meet basic lighting requirements. Because pedestrian traffic is lower at night, what is often needed is not higher lighting intensity, but a more suitable lighting range. However, most existing streetlights are fixed on poles, making it impossible to raise or rotate them for adjustment, thus limiting the lighting range and reducing the effectiveness of the streetlights. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide an adjustable solar street light that can improve the lighting effect of the street light.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An adjustable solar street light includes a base, a pole fixedly mounted on the base, a mounting block fixedly mounted on the top of the pole, mounting frames symmetrically mounted on the mounting blocks, a solar panel fixedly mounted on the mounting frames, and a battery electrically connected to the solar panel fixedly mounted on the base. The pole is provided with an adjustment component. The adjustment assembly includes a slide groove on a mounting bracket, a linkage block slidably mounted in the slide groove, a horizontal rod symmetrically fixedly mounted on the linkage block, a rotating rod fixedly mounted on the horizontal rod, a lamp housing rotatably mounted on the rotating rod, a controller electrically connected to a battery fixedly mounted on the base, a lamp body electrically connected to the controller fixedly mounted on the lamp housing, a slide groove on the top wall of the lamp housing, a slider slidably mounted in the slide groove, a connecting rod hinged to the slider, a mounting plate fixedly mounted on the linkage block, and the end of the connecting rod away from the slider rotatably connected to the mounting plate, and a vertical rod for pushing the lamp housing to rotate on the mounting bracket.

[0007] Furthermore, a motor electrically connected to the controller is fixedly installed on the base, a transmission rod is fixedly installed on the output end of the motor, a vertical groove is provided on the side wall of the rod, a sliding plate fixedly connected to the linkage block is slidably installed in the vertical groove, a spiral groove is provided on the transmission rod, a protrusion that slides with the spiral groove is fixedly installed on the sliding plate, and a spring is installed between the rotating rod and the horizontal rod.

[0008] Furthermore, a limiting rod is horizontally slidably installed on the horizontal rod, and a first spring is installed between the limiting rod and the horizontal rod. The rotating rod is evenly provided with limiting grooves that cooperate with the limiting rod. A magnet is fixedly installed on the limiting rod, and an electromagnet that cooperates with the magnet is fixedly installed on the horizontal rod. The electromagnet is electrically connected to the motor.

[0009] Furthermore, a first telescopic tube is installed between the top wall of the linkage block and the mounting block, an mounting plate is fixedly installed on the rod, and a second telescopic tube is installed between the linkage block and the mounting plate.

[0010] Furthermore, a horizontal groove is provided on the lamp housing, a cleaning block is slidably installed in the horizontal groove, a brush plate is fixedly installed on the cleaning block, and a third telescopic tube is installed between the cleaning block and the horizontal groove. A first cavity is provided on the first telescopic tube, and an air pipe communicating with the third telescopic tube is inserted into the first cavity.

[0011] Furthermore, the mounting block is provided with a water collection trough, the brush plate is provided with a water cavity, the water cavity is provided with water holes evenly distributed, the second telescopic tube is provided with a second cavity, a first one-way valve is inserted into the second cavity, a first water pipe communicating with the water collection trough is fixedly installed on the input end of the first one-way valve, a second one-way valve is inserted into the second cavity, and a second water pipe communicating with the water cavity is fixedly installed on the output end of the second one-way valve.

[0012] Furthermore, a filter screen is fixedly installed on the water collection tank, a scraper is rotatably installed on the top wall of the filter screen, and the scraper is fixedly connected to the transmission rod. A drain port is opened on the water cavity, and a guide plate is fixedly installed on the side wall of the mounting block.

[0013] Furthermore, baffles are symmetrically fixedly installed on the slider.

[0014] Furthermore, a ball bearing is fixedly installed at the bottom end of the vertical rod.

[0015] Furthermore, a linkage rod is fixedly installed on the mounting bracket, and the vertical rod is threaded onto the bottom end of the linkage rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this scheme, the vertical rod and the lamp housing cooperate. In the early morning, the motor drives the spiral groove to rotate through the transmission rod, so that the protrusion pushes the lamp housing through the sliding plate and the linkage block, thereby realizing the overall height of the lamp body. Simultaneously, the lamp housing is deflected by the pushing action of the vertical rod during the rising process, thereby adjusting the illumination angle of the lamp body, expanding the lighting range, and meeting the basic lighting needs of the road in the early morning. When all the street lights are turned on in the evening, the lamp body is reset to reduce the height and adjust the angle, concentrate the lighting intensity, accurately cover the road and sidewalk, avoid lighting waste, and improve the safety of pedestrians and vehicles.

[0017] (2) This solution uses the combination of limit rod, electromagnet and spring to lock the rotating rod after the lamp body angle is adjusted, to prevent the lamp body from swinging due to external wind force, to ensure lighting stability and extend the service life of the street lamp.

[0018] (3) This solution sets up a cleaning structure. During the movement of the linkage block, the first telescopic tube will be squeezed back and forth. The airflow in the first cavity flows back and forth through the air pipe to the third telescopic tube, thereby driving the cleaning block and brush plate to move back and forth to wipe the surface of the lamp body and remove the dust and stains attached to the surface. It has the ability to self-clean the fluid. When there is precipitation, the water collection tank collects the precipitation and, in conjunction with the pumping action of the second telescopic tube, sprays the water onto the surface of the lamp body to soften stubborn stains. Under dry and waterless conditions, the airflow generated by the compression of the first telescopic tube blows and removes dust from the surface of the lamp body, always ensuring the light transmittance of the lamp body and avoiding the lighting effect being affected by stains.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8An adjustable solar street light includes a base 101, a pole 102 fixedly mounted on the base 101, a mounting block 103 fixedly mounted on the top of the pole 102, mounting frames 104 symmetrically fixedly mounted on the mounting blocks 103, a solar panel 105 fixedly mounted on the mounting frames 104, and a battery 106 electrically connected to the solar panel 105 fixedly mounted on the base 101. An adjustment component is provided on the pole 102. The adjustment assembly includes a slide groove 208 formed on the mounting frame 104. A linkage block 201 is slidably installed in the slide groove 208. A horizontal rod 202 is symmetrically fixedly installed on the linkage block 201. A rotating rod 203 is fixedly installed on the horizontal rod 202. A lamp housing 204 is rotatably installed on the rotating rod 203. A controller 205 electrically connected to a storage battery 106 is fixedly installed on the base 101. A lamp body 206 electrically connected to the controller 205 is fixedly installed on the lamp housing 204. A slide groove 208 is formed on the top wall of the lamp housing 204. A slider 207 is slidably installed in the slide groove 208. A connecting rod 209 is hinged to the slider 207. A mounting plate 210 is fixedly installed on the linkage block 201. The end of the connecting rod 209 away from the slider 207 is rotatably connected to the mounting plate 210. A vertical rod 211 for pushing the lamp housing 204 to rotate is provided on the mounting frame 104.

[0023] A motor 301 electrically connected to a controller 205 is fixedly mounted on the base 101. A transmission rod 302 is fixedly mounted on the output end of the motor 301. A vertical groove is provided on the side wall of the rod 102. A sliding plate 303 fixedly connected to a linkage block 201 is slidably mounted in the vertical groove. A spiral groove 304 is provided on the transmission rod 302. A protrusion 305 that slides with the spiral groove 304 is fixedly mounted on the sliding plate 303. A spring 306 is installed between the rotating rod 203 and the horizontal rod 202.

[0024] A limiting rod 401 is horizontally slidably mounted on the horizontal rod 202, and a first spring 402 is installed between the limiting rod 401 and the horizontal rod 202. The rotating rod 203 is evenly provided with limiting grooves 403 that cooperate with the limiting rod 401. A magnet block 404 is fixedly mounted on the limiting rod 401. An electromagnet 405 that cooperates with the magnet block 404 is fixedly mounted on the horizontal rod 202, and the electromagnet 405 is electrically connected to the motor 301.

[0025] During the day, the solar panel 105 converts solar energy into electrical energy and stores it in the battery 106. When the light dims and lighting is needed, the controller 205 connects the battery 106 to the lamp body 206 to provide illumination. After midnight, as some solar streetlights turn off, the controller 205 controls the motor 301 to rotate the transmission rod 302. During the rotation of the transmission rod 302, the spiral groove 304 rotates. Because the protrusion 305 and the spiral groove 304 are in sliding engagement, and the sliding plate 303, which is slidably mounted on the rod 102, is fixedly connected to the protrusion 305, the protrusion 305 cannot rotate. When the spiral groove 304 rotates, the protrusion 305 drives the sliding plate 303 to move upward along the vertical groove. During the upward movement of the sliding plate 303, the linkage block 201 moves upward, and during the upward movement of the linkage block 201, the lamp body 206 moves upward, thereby expanding the illumination range of the lamp body 206. Simultaneously, as the linkage block 201 drives the lamp body 206 upward, the vertical rod 211 gradually contacts the top wall of the lamp housing 204 near the mounting block 103, applying a pushing force to the top wall of the lamp housing 204. Under the action of the pushing force, the lamp housing 204 drives the rotating rod 203 to rotate around the horizontal rod 202. During the rotation of the lamp housing 204, the slider 207 slides along the slide groove 208. During the sliding of the slider 207, the connecting rod 209 rotates around the mounting plate 210, thereby improving the stability of the lamp housing 204. The lamp housing 204 drives the lamp body 206 to rotate as the rotating rod 203 rotates around the horizontal rod 202, thereby achieving the purpose of adjusting the angle of the lamp body 206. When the lamp body 206 rotates away from the rod 102, the illumination range of the lamp body 206 can be further expanded, thereby improving the lighting effect of the solar street light.

[0026] As the lamp housing 204 drives the rotating rod 203 to rotate, the spring 306 begins to store power and tends to return to its original position. Later that evening, all the solar streetlights are turned on. At this time, the motor 301 drives the transmission rod 302 to reverse. During the reversal of the transmission rod 302, the linkage block 201 is driven downwards to reset via the spiral groove 304, protrusion 305, and sliding plate 303. The downward reset of the linkage block 201 causes the lamp housing 204 and lamp body 206 to move downwards. At this time, the spring 306 extends and drives the lamp housing 204 to reverse and reset. Since all the solar streetlights are on at this time, large-area illumination is not required. By lowering the height of the lamp body 206 and rotating its angle, the illumination intensity of the solar streetlights on the road and sidewalk can be increased, further improving the lighting effect.

[0027] When motor 301 is energized, electromagnet 405 is energized and generates a magnetic field. Under the action of the magnetic field, magnet block 404 drives limit rod 401 to move towards electromagnet 405. At this time, first spring 402 is stretched and has a tendency to return to its original state. After the limit rod 401 moves, it gradually disengages from the limit groove 403, and rotating rod 203 can rotate normally. When the lamp body 206 angle adjustment is completed, motor 301 is de-energized, electromagnet 405 is de-energized and the magnetic field disappears. First spring 402 contracts and drives limit rod 401 to insert into limit groove 403, thereby locking rotating rod 203 and effectively preventing external wind from causing lamp body 206 to sway, affecting lighting effect and stability.

[0028] like Figures 3 to 8 As shown, a first telescopic tube 501 is installed between the top wall of the linkage block 201 and the mounting block 103, an mounting plate 502 is fixedly installed on the rod body 102, and a second telescopic tube 503 is installed between the linkage block 201 and the mounting plate 502.

[0029] A horizontal groove is provided on the lamp housing 204. A cleaning block 504 is slidably installed in the horizontal groove. A brush plate 505 is fixedly installed on the cleaning block 504. A third telescopic tube 506 is installed between the cleaning block 504 and the horizontal groove. A first cavity 507 is provided on the first telescopic tube 501. An air pipe 508 communicating with the third telescopic tube 506 is inserted into the first cavity 507.

[0030] The mounting block 103 has a water collection tank 601, the brush plate 505 has a water cavity 602, the water cavity 602 has water holes evenly distributed, the second telescopic tube 503 has a second cavity 603, the second cavity 603 has a first one-way valve 604 inserted into the second cavity 603, the input end of the first one-way valve 604 is fixedly installed with a first water pipe 605 communicating with the water collection tank 601, the second cavity 603 has a second one-way valve 606 inserted into the second cavity 603, the output end of the second one-way valve 606 is fixedly installed with a second water pipe 607 communicating with the water cavity 602.

[0031] By adopting the above technical solution, during the movement of the linkage block 201, the first telescopic tube 501 and the second telescopic tube 503 will be compressed or stretched respectively. During the reciprocating extension and retraction of the first telescopic tube 501 and the second telescopic tube 503, the vertical groove can be blocked, thereby preventing external impurities from entering the spiral groove 304 through the vertical groove and affecting the normal sliding of the protrusion 305 along the spiral groove 304, thus improving the stability of the device operation. Furthermore, when the linkage block 201 moves upward, the first telescopic tube 501 is compressed, at which point the first telescopic tube 505... Airflow in the first cavity 507 of the telescopic tube 501 flows through the air pipe 508 to the third telescopic tube 506, increasing the pressure inside the third telescopic tube 506. Under the action of pressure, the third telescopic tube 506 extends and drives the cleaning block 504 to slide along the horizontal groove. During the movement of the cleaning block 504, the brush plate 505 moves. During the movement of the brush plate 505, the stains on the surface of the lamp body 206 can be cleaned, thereby avoiding excessive stains on the surface of the lamp body 206 after long-term use, which would affect the lighting effect.

[0032] In some parts of my country, there are many mosquitoes and rain in summer, and places with light sources easily attract mosquitoes, causing insect residue to easily adhere to the surface of the lamp body 206, which is difficult to clean and seriously affects the lighting effect. When it rains, the water collection tank 601 collects rainwater. During the upward movement of the linkage block 201, the second telescopic tube 503 is stretched. At this time, the second cavity 603 draws rainwater from the water collection tank 601 through the first one-way valve 604 and the first water pipe 605. Then, when the linkage block 201 moves downward, the first telescopic tube 501 extends, and the first cavity 503 draws rainwater from the water collection tank 601. 07. Air is drawn in from the third telescopic tube 506 through the air pipe 508, causing the third telescopic tube 506 to contract and drive the brush plate 505 to reset through the cleaning block 504. At the same time, the second telescopic tube 503 is compressed. At this time, the rainwater in the second cavity 603 flows into the water cavity 602 through the second one-way valve 606 and the second water pipe 607, and is evenly sprayed onto the surface of the lamp body 206 through the water holes on the water cavity 602. This can wet the insect glue on the surface of the lamp body 206, making it easier for the brush plate 505 to clean the insect glue and effectively improve the lighting effect.

[0033] During the dry autumn and winter seasons with less rain, the air is dry and dust easily floats in. At this time, there may be no rainwater in the water collection tank 601. The second cavity 603 will draw air from the water collection tank 601 through the first one-way valve 604 and the first water pipe 605. When the second telescopic pipe 503 is compressed, the airflow in the second cavity 603 will be blown through the second one-way valve 606, the second water pipe 607, the water cavity 602, and the water hole onto the surface of the lamp body 206 being cleaned by the brush plate 505, so that the dust will be separated from the surface of the lamp body 206, effectively improving the lighting effect.

[0034] like Figure 7As shown, a filter screen 701 is fixedly installed on the water collection tank 601, a scraper 702 is rotatably installed on the top wall of the filter screen 701, and the scraper 702 is fixedly connected to the transmission rod 302. A drain port is provided on the water cavity 602, and a guide plate 703 is fixedly installed on the side wall of the mounting block 103.

[0035] By adopting the above technical solution, when rainwater and airflow pass through the filter screen 701, the filter screen 701 filters the dirt in the rainwater and airflow. Then, during the rotation of the transmission rod 302, the transmission rod 302 drives the scraper 702 to rotate, and during the rotation of the scraper 702, the dirt is driven to rotate. Then, under the action of centrifugal force, the dirt flows out through the drain and guide plate 703, thereby preventing the dirt from affecting the normal flow of airflow and rainwater to the water collection tank 601.

[0036] like Figure 2 As shown, baffles 801 are symmetrically fixedly installed on the slider 207.

[0037] A ball bearing 802 is fixedly installed at the bottom end of the vertical rod 211.

[0038] A linkage rod 803 is fixedly installed on the mounting bracket 104, and the vertical rod 211 is threaded onto the bottom end of the linkage rod 803.

[0039] By adopting the above technical solution, when the slider 207 moves along the slide groove 208, the slide groove 208 can be blocked by setting the baffle 801, thereby preventing dirt from entering the slide groove 208 and affecting the movement of the slider 207; and the ball bearing 802 set at the bottom of the vertical rod 211 can convert the sliding friction between the vertical rod 211 and the top wall of the lamp body 206 into rolling friction, thereby reducing the wear of the vertical rod 211 and the lamp body 206. When it is necessary to adjust the rotation angle of the lamp body 206, the user can rotate the vertical rod 211. Since the vertical rod 211 is threadedly engaged with the linkage rod 803, the height of the ball bearing 802 at the bottom of the vertical rod 211 can be adjusted. When the lamp housing 204 moves the lamp body 206 upward, the ball bearing 802 at the bottom of the vertical rod 211 will push the lamp housing 204 to rotate the lamp body 206. The height to which the lamp housing 204 rises is fixed. By adjusting the height of the ball bearing 802, the rotation angle of the lamp body 206 can be adjusted.

[0040] Instructions for use: First, during the day when there is sunlight, the solar panel 105 installed on the lamp holder will automatically absorb solar energy, convert it into electrical energy, and store it in the battery 106 of the base 101; when the light dims, such as at dusk, and the lighting needs are met, the controller 205 will automatically connect the battery 106 to the lamp body 206, and the lamp body 206 will automatically light up to provide lighting for the road and sidewalk; after midnight, some streetlights will be turned off.

[0041] Early morning adjustment: After midnight, the controller 205 controls the motor 301 to start, which drives the transmission rod 302 to rotate. Through the cooperation of the spiral groove 304 and the protrusion 305, the sliding plate 303 and the linkage block 201 move upward, thereby raising the lamp body 206. At the same time, the vertical rod 211 pushes the lamp housing 204 to rotate, adjusting the angle of the lamp body 206 and expanding the illumination range to adapt to the scene where the light is dim in the early morning and the lighting needs are wider.

[0042] Evening reset: At dusk, all streetlights are turned on, motor 301 drives transmission rod 302 to reverse, linkage block 201 and lamp body 206 synchronously reset downwards, spring 306 extends and drives lamp housing 204 to reverse, lamp body 206 angle and height return to a state suitable for concentrated road lighting, improve lighting intensity and meet the needs of pedestrians and vehicles.

[0043] In addition, after the lamp body 206 angle is adjusted, the motor 301 automatically cuts off the power, the electromagnet 405 loses its magnetic field, the first spring 402 contracts, and drives the limit rod 401 to insert into the limit groove 403 of the rotating rod 203, locking the rotating rod 203 to prevent the lamp body 206 from swinging due to external wind force.

[0044] Then, when the linkage block 201 moves upward, the first telescopic tube 501 is compressed. At this time, the airflow in the first cavity 507 of the first telescopic tube 501 flows through the air pipe 508 into the third telescopic tube 506, causing the third telescopic tube 506 to extend. The cleaning block 504 drives the brush plate 505 to move, cleaning the stains on the surface of the lamp body 206.

[0045] Simultaneously, as the linkage block 201 moves upward, the second telescopic tube 503 is stretched. At this time, the second cavity 603 draws rainwater from the water collection tank 601 through the first one-way valve 604 and the first water pipe 605. When the linkage block 201 moves downward, the first telescopic tube 501 extends, and the first cavity 507 draws air from the third telescopic tube 506 through the air pipe 508, thereby causing the third telescopic tube 506 to contract and drive the brush plate 505 to reset through the cleaning block 504. At the same time, the second telescopic tube 503 is compressed. At this time, the rainwater in the second cavity 603 flows into the water cavity 602 through the second one-way valve 606 and the second water pipe 607, and is evenly sprayed onto the surface of the lamp body 206 through the water holes on the water cavity 602, which can wet the insect glue on the surface of the lamp body 206, thus making it easier for the brush plate 505 to clean the insect glue.
