Description

Technical Field

[0001] The invention relates to the field of urban street lamps, and in particular to an urban street lamp capable of adjusting light intensity. Background Art

[0002] Urban street lights with adjustable light intensity are able to monitor the natural light intensity of the surrounding environment in real time through light sensors. During the day or when there is sufficient light, the street lights can automatically reduce their brightness or even turn off to avoid unnecessary energy waste; at night or when there is insufficient light, they can automatically adjust to the appropriate brightness to ensure road lighting.

[0003] The publication number is CN116202067B, which specifically refers to an urban street lamp with adjustable light intensity. It includes a street lamp body, a reversing device, an automatic pre-tightening device, a wind driving mechanism and a light sensing element protection device. The reversing device is arranged on the street lamp body, the automatic pre-tightening device is arranged on the reversing device, and the wind driving mechanism is arranged on the automatic pre-tightening device. With the acceleration of urbanization, urban street lamps with adjustable light intensity are widely used in urban lighting systems. This type of street lamp uses a photosensitive element to sense the light intensity of the surrounding environment, and then automatically adjusts the brightness of the street lamp to achieve the dual goals of energy saving and meeting lighting needs. However, the street lamp is exposed to the outdoor environment for a long time, and the photosensitive element is easily affected by dust, dirt, insect secretions and other contaminants. To solve this problem, the current common practice is to use a combination of rubber and a brush to clean the outer protective cover of the photosensitive element. Rubber has a certain degree of flexibility and friction. When it comes into contact with the surface of the protective cover, it can use its own elasticity to fit the curved surface and effectively remove some of the dirt adsorbed on the protective cover; the brush can penetrate into some tiny gaps and textures to clean dust and small particles that are difficult for rubber to reach. The combination of the two can ensure the cleanliness of the protective cover of the photosensitive element to a certain extent and maintain the normal operation of the photosensitive element, but the existing cleaning method has obvious defects. In the process of cleaning the protective cover back and forth, after the rubber and brush absorb the dirt, due to the lack of an effective dirt locking mechanism, the dirt sometimes adheres to the outside of the rubber and the brush. When the rubber and the brush return, the absorbed dirt may re-adhere to the outside of the protective cover, causing secondary pollution, which not only reduces the cleaning effect, but also may cause the light sensing element to perceive the light intensity to deviate, affecting the dimming accuracy of the street lamp. For example, in some areas with severe industrial pollution, there is a lot of dust and pollutants in the air, and the dirt on the protective cover of the street light sensing element accumulates quickly. Even if the rubber and brush are frequently used for cleaning, due to the existence of the secondary pollution problem, the surface of the protective cover is always difficult to keep clean, resulting in frequent abnormal brightness adjustment of the street lamp.

[0004] To solve the above problems, a city street lamp with adjustable light intensity is proposed. Summary of the invention

An elastic telescopic rod 609 is fixedly connected to one side of a support plate 3, and a cleaning plate 610 is fixedly connected to one end of the elastic telescopic rod 609 close to the first support plate 3. A first guide rod 611 fixedly connected to the elastic telescopic rod 609 is arranged on the inner side of the first guide groove 608, a point a is arranged on the outer side of one end of the first guide groove 608, a point b is arranged on the inner side of one end of the first guide groove 608, a point c is arranged on the outer side of the other end of the first guide groove 608, and a point d is arranged on the inner side of the other end of the first guide groove 608. When the first elastic telescopic rod 609 is in a natural state, the vertical height of the first guide rod 611 is higher than the vertical height of point c of the first guide groove 608 and lower than the vertical height of point d. Point a of the first guide groove 608 is closer to the vertical center axis of the first support plate 3 than point b, and point c of the first guide groove 608 is farther away from the vertical center axis of the first support plate 3 than point d.

[0035] The sliding assembly 71 includes a second gear 7101 disposed between the residual gear 603 and the spoon-shaped blade 602 and fixedly connected to the first rotating shaft 601, a rack 7102 is disposed on the outer side of the second gear 7101, a slide groove 7103 is disposed on the side of the rack 7102 away from the second gear 7101 and close to the first supporting plate 3, a first slider 7104 is disposed on the inner side of the slide groove 7103, and a linear telescopic rod 7105 is fixedly connected to the end of the first slider 7104 away from the second gear 7101, and the linear telescopic rod 7105 is fixedly connected to the end of the first slider 7104 away from the second gear 7101. The connection mode between the first support plate 7105 and the first support plate 3 is a fixed connection. The outer side surface of the second support plate 607 is provided with a second guide groove 7106. The inner side of the second guide groove 7106 is provided with a second guide rod 7107 fixedly connected to the rack 7102. The vertical center axis of the slide groove 7103 is parallel to the vertical center axis of the rack 7102, and the inner side surface of the slide groove 7103 is in contact with the outer side surface of the first slider 7104. The width of the first slider 7104 close to the second gear 7101 is greater than the width of the first slider 7104 away from the second gear 7101. The width of the second gear 7101 allows the first slider 7104 to slide inside the slide groove 7103, but will not move out of the slide groove 7103. The horizontal center axis of the linear telescopic rod 7105 is perpendicular to the vertical center axis of the rack 7102, so that the rack 7102 can move laterally. The upper outer vertex of the second guide groove 7106 is closer to the linear telescopic rod 7105 than the upper inner vertex of the second guide groove 7106, and the lower outer vertex of the second guide groove 7106 is closer to the linear telescopic rod 7105 than the upper inner vertex of the second guide groove 7106. The inner vertex of the lower end of the groove 7106 is further away from the linear telescopic rod 7105, so that when the second guide rod 7107 moves to the upper end of the second guide groove 7106 and moves downward, the second guide rod 7107 can move to the inside of a side of the second guide groove 7106 close to the linear telescopic rod 7105. Similarly, when the second guide rod 7107 moves to the lower end of the second guide groove 7106 and moves upward, the second guide rod 7107 can move to the inside of a side of the second guide groove 7106 away from the linear telescopic rod 7105.

[0036] The pulling assembly 72 includes a third support plate 7201 fixedly connected to the outer side above the rotating rod 2, a connecting plate 7202 is rotatably connected to the inner side of the third support plate 7201, the central axis of the connecting plate 7202 is parallel to the upper plane of the first support plate 3, one end of the connecting plate 7202 is fixedly connected to a reversing plate 7203, a third guide groove 7204 is provided on the side of the rack 7102 away from the second gear 7101 and away from the first support plate 3, a third guide rod 7205 is provided on the inner side of the third guide groove 7204, one end of the third guide rod 7205 is fixedly connected to a pull rod 7207, and the connecting plate 7202 A second slider 7206 is slidingly connected to one side close to the first gear 604, and the connection between the pull rod 7207 and the second slider 7206 is a rotational connection. The third guide groove 7204 is composed of a plurality of vertical straight grooves connected to an arc groove, and the third guide groove 7204 and the third guide rod 7205 are matched in a clearance fit, so that the third guide rod 7205 will not rock left and right when moving on the inner side of the vertical straight groove of the third guide groove 7204, but will rock left and right when moving on the inner side of the arc groove of the third guide groove 7204, and the connection between the pull rod 7207 and the first support plate 3 is a sliding connection.

[0037] When the airflow passes through, it drives the spoon-shaped blade 602 to rotate, and then drives the first rotating shaft 601 to rotate, and drives the residual gear 603 fixed on the outside of the first rotating shaft 601 to rotate. When the residual gear 603 has teeth in contact with the outer surface of the first gear 604, the first gear 604 rotates, driving the second rotating shaft 605 and the elastic telescopic rod 609 to rotate, driving the cleaning plate 610 to rotate to clean the outer side of the protective cover 4. At this time, the elastic telescopic rod 609 drives the first guide rod 611 to rotate, and the first guide rod 611 rotates. 11 is arranged on the lower inner side of the first guide groove 608. After the cleaning plate 610 is cleaned, when the residual gear 603 has no teeth in contact with the outer surface of the first gear 604, the torsion spring 606 accumulates force when the first gear 604 rotates. At this time, the torsion spring 606 drives the first gear 604 to reset, and drives the elastic telescopic rod 609 and the first guide rod 611 to reset. Because point a of the first guide groove 608 is closer to the central axis of the first support plate 3 than point b, and point c of the first guide groove 608 is farther away from the central axis of the first support plate 3 than point d. The elastic telescopic rod 609 drives the first guide rod 611 to rotate. The first guide rod 611 is arranged on the lower inner side of the first guide groove 608, and is located at point c of the first guide groove 608 at this time. At this time, the first elastic telescopic rod 609 is in a natural state. The height of the first elastic telescopic rod 609 in the natural state is higher than the height of point c, so that when the first gear 604 rotates in the opposite direction, the first guide rod 611 will move to the upper inner side of the first guide groove 608, so that the cleaning plate 610 will not contact the protective cover 4, and the cleaning plate 610 will not contact the protective cover 4. After the gear 604 is reset, the first guide rod 611 is located at point a. Since the first elastic telescopic rod 609 is in a natural state, the height of the first guide rod 611 is lower than the height of point d. When the residual gear 603 drives the first gear 604 to rotate again, the first guide rod 611 will move to the lower inner side of the first guide groove 608 to work again. Since the cleaning plate 610 will not contact the protective cover 4 when it is reset, the protective cover 4 is cleaned in one direction, which reduces secondary pollution, makes the cleaning effect better, and reduces the abnormality of street lamp brightness adjustment.

[0038] Because the torsion spring 606 accumulates force when the first gear 604 rotates, the accumulated force is released in a short time when the torsion spring 606 resets, so that the reset impact force of the elastic telescopic rod 609 and the cleaning plate 610 becomes larger, and the adhesion on the cleaning plate 610 can be partially detached under the action of inertia, so that the cleaning effect is better.

[0039] When the first rotating shaft 601 rotates, it drives the second gear 7101 to rotate, drives the rack 7102 to move upward, and drives the second guide rod 7107 to move upward on the inner side of the second guide groove 7106. Because the outer vertex of the upper end of the second guide groove 7106 is closer to the linear telescopic rod 7105 than the inner vertex of the upper end of the second guide groove 7106, and the outer vertex of the lower end of the second guide groove 7106 is farther away from the linear telescopic rod 7105 than the inner vertex of the lower end of the second guide groove 7106, when the second guide rod 7107 moves to the upper outer side of the second guide groove 7106, the second gear 7101 loses control of the rack 7102. At this time, the second guide rod 7107 moves to the side away from the linear telescopic rod 7105 under the action of gravity, and the rack 7102 realizes reciprocating motion up and down. When moving up and down, the third guide groove 7204 is driven to perform up and down reciprocating motion. Since the third guide groove 7204 is composed of a plurality of vertical straight grooves connected with an arc groove, and the third guide groove 7204 and the third guide rod 7205 are matched in a clearance match, the third guide groove 7204 of the rack 7102 intermittently drives the third guide rod 7205 to perform lateral reciprocating motion. Since the connecting plate 7202 and the third support plate 7201 are rotationally connected, the connecting plate 7202 and the second slider 7206 are slidingly connected, and the connection mode of the pull rod 7207 and the second slider 7206 is a rotational connection, the third guide rod 7205 drives the pull rod 7207, the second slider 7206 and the connecting plate 7202 to perform intermittent reciprocating swing, so that the reversing plate 7203 indirectly swings, thereby increasing the wind receiving range of the reversing plate 7203 and enhancing the wind energy utilization efficiency.

[0040] When the reversing plate 7203 swings indirectly, the airflow is intercepted, and the airflow pushes the reversing plate 7203 to rotate. The force is transmitted from the reversing plate 7203 to the connecting plate 7202, and then to the second slider 7206, the pull rod 7207 and the third guide rod 7205, and then to the rack 7102, the linear telescopic rod 7105 and the top of the first support plate 3, so that the first support plate 3 rotates, so that the first support plate 3 can face the airflow in multiple directions, and the protective cover 4 is cleaned, so that the cleaning effect is better.

[0041] By increasing the wind receiving range of the reversing plate 7203, the wind direction can be changed in time, reducing the reverse movement of the spoon-shaped blade 602 caused by a sudden change in wind direction, thereby reducing the possibility of direct reverse movement of the cleaning plate 610 during the cleaning process and reducing secondary pollution.
