Description

Technical Field

[0001] The present invention relates to the field of urban street lamps, and particularly to an urban street lamp with adjustable light intensity. Background Art

[0002] An urban street lamp with adjustable light intensity is a kind of street lamp that can real-time monitor the natural illuminance of the surrounding environment through a light sensor. During the day or when the light is sufficient, the street lamp can automatically reduce its brightness or even turn off to avoid unnecessary energy waste; at night or when the light is insufficient, it can automatically adjust to an appropriate brightness to ensure road lighting.

[0003] The publication number is CN116202067B, specifically referring to an urban street lamp with adjustable light intensity. It includes a street lamp body, a commutation device, an automatic pre-tightening device, a wind driving mechanism, and a light sensor protection device. The commutation device is arranged on the street lamp body, the automatic pre-tightening device is arranged on the commutation device, and the wind driving mechanism is arranged on the automatic pre-tightening device. With the acceleration of the urbanization process, urban street lamps with adjustable light intensity are widely used in urban lighting systems. These street lamps use light sensors to sense the light intensity of the surrounding environment and then automatically adjust the brightness of the street lamps to achieve the dual purposes of energy conservation and meeting lighting requirements. However, since the street lamps are long-term exposed to the outdoor environment, the light sensors are extremely vulnerable to the influence of dirt such as dust, dirt, and insect secretions. To solve this problem, the common current practice is to use a combination of rubber and a brush to clean the outer protective cover of the light sensor. Rubber has a certain 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 fine gaps and textures to clean the dust and small particle impurities that are difficult for the rubber to reach. The two cooperate to ensure the cleanliness of the light sensor protective cover to a certain extent and maintain the normal operation of the light sensor. However, the existing cleaning method has obvious defects. During the process of cleaning the protective cover back and forth, after the rubber and the brush adsorb 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 adsorbed dirt may re-adhere to the outside of the protective cover, causing secondary pollution. This not only reduces the cleaning effect but also may cause the light sensor to have a deviation in the perception of light intensity, affecting the dimming accuracy of the street lamp. For example, in some areas with relatively serious industrial pollution, there are more dust and pollutants in the air, and the dirt on the protective cover of the street lamp light sensor accumulates quickly. Even if the rubber and the brush are frequently used for cleaning, due to the existence of secondary pollution problems, 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 kind of urban street lamp with adjustable light intensity is proposed. Summary of the Invention

[0032] Please refer to Figures 1-9 , the present invention provides a technical solution: an urban street lamp with adjustable light intensity, including a street lamp main body 1, a rotating rod 2 arranged above the street lamp main body 1, a first support plate 3 fixedly connected above the rotating rod 2, a protective cover 4 fixedly connected to one side above the first support plate 3, a photosensitive member 5 arranged inside the protective cover 4, a rotating mechanism 6 arranged above the first support plate 3, and a swinging mechanism 7 arranged on one side of the first support plate 3;

[0034] The rotating mechanism 6 includes a first rotating shaft 601 rotatably connected to the inner side of the first support plate 3. Spoon-shaped blades 602 are fixedly connected to both ends of the first rotating shaft 601. A residual gear 603 fixedly connected to the first rotating shaft 601 is arranged between the first support plate 3 and the spoon-shaped blades 602. A first gear 604 is arranged outside the residual gear 603. A second rotating shaft 605 is fixedly connected to the inside of the first gear 604. A torsion spring 606 is fixedly connected between the first gear 604 and the first support plate 3. On the other side above the first support plate 3, a second support plate 607 is fixedly connected. The central axis of the second support plate 607 is perpendicular to the central axis of the first support plate 3, and the outer appearance structure of the second support plate 607 is arc-shaped. A first guide groove 608 is arranged on the inner side surface of the second support plate 607. Both the upper and lower ends of the first guide groove 608 are arc-shaped. An elastic telescopic rod 609 is fixedly connected to the side of the second rotating shaft 605 away from the first support plate 3. A cleaning plate 610 is fixedly connected to the 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 inside the first guide groove 608. A point a is arranged outside one end of the first guide groove 608, a point b is arranged inside one end of the first guide groove 608, a point c is arranged outside the other end of the first guide groove 608, and a point d is arranged inside the other end of the first guide groove 608. When the 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 central axis of the first support plate 3 than point b, and point c of the first guide groove 608 is farther from the vertical central axis of the first support plate 3 than point d.

[0035] The sliding component 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 outside the second gear 7101. A chute 7103 is disposed on the side of the rack 7102 away from the second gear 7101 and close to the first support plate 3. A first slider 7104 is disposed inside the chute 7103. One end of the first slider 7104 away from the second gear 7101 is fixedly connected to a linear telescopic rod 7105. The linear telescopic rod 7105 is fixedly connected to the first support plate 3. A second guiding groove 7106 is formed on the outer side surface of the second support plate 607. A second guiding rod 7107 fixedly connected to the rack 7102 is disposed inside the second guiding groove 7106. The vertical central axis of the chute 7103 is parallel to the vertical central axis of the rack 7102, and the inner side surface of the chute 7103 is in contact with the outer side surface of the first slider 7104. Moreover, 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, so that the first slider 7104 can slide inside the chute 7103 but will not move out of the inside of the chute 7103. The horizontal central axis of the linear telescopic rod 7105 is perpendicular to the vertical central axis of the rack 7102, so that the rack 7102 can move horizontally. The upper outer vertex of the second guiding groove 7106 is closer to the linear telescopic rod 7105 than the upper inner vertex of the second guiding groove 7106, and the lower outer vertex of the second guiding groove 7106 is farther from the linear telescopic rod 7105 than the lower inner vertex of the second guiding groove 7106, so that when the second guiding rod 7107 moves downward to the upper end of the second guiding groove 7106, the second guiding rod 7107 can move into the inner side of the second guiding groove 7106 close to the linear telescopic rod 7105. Similarly, when the second guiding rod 7107 moves upward to the lower end of the second guiding groove 7106, the second guiding rod 7107 can move into the inner side of the second guiding groove 7106 away from the linear telescopic rod 7105.

[0036] The pulling component 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 guiding 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 guiding rod 7205 is provided inside the third guiding groove 7204. One end of the third guiding rod 7205 is fixedly connected to a pull rod 7207. A second slider 7206 is slidably connected to the side of the connecting plate 7202 close to the first gear 604. The pull rod 7207 is rotatably connected to the second slider 7206. The third guiding groove 7204 is composed of a plurality of vertical straight grooves communicated with arc grooves, and the third guiding groove 7204 and the third guiding rod 7205 are in clearance fit, so that the third guiding rod 7205 will not sway left and right when moving inside the vertical straight groove of the third guiding groove 7204, and will sway left and right when moving inside the arc groove of the third guiding groove 7204. The pull rod 7207 is slidably connected to the first support plate 3.

[0037] When the air flow passes by, it will drive the spoon-shaped blade 602 to rotate, and then drive the first rotating shaft 601 to rotate, driving the incomplete gear 603 fixed on the outside of the first rotating shaft 601 to rotate. When there are teeth on the incomplete gear 603 in contact with the outer surface of the first gear 604, the first gear 604 will be driven to rotate, 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. The first guide rod 611 is arranged on the inner side below the first guide groove 608. After the cleaning plate 610 finishes cleaning, when there are no teeth on the incomplete gear 603 in contact with the outer surface of the first gear 604, the torsion spring 606 is energized when the first gear 604 rotates. At this time, the torsion spring 606 drives the first gear 604 to reset, driving the elastic telescopic rod 609 and the first guide rod 611 to reset. Since 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 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 inner side below the first guide groove 608. At this time, it is located at point c of the first guide groove 608. At this time, the elastic telescopic rod 609 is in a natural state. The height of the first guide rod 611 in the natural state of the elastic telescopic rod 609 is higher than the height of point c, so that when the first gear 604 rotates in the reverse direction, the first guide rod 611 will move to the inner side above the first guide groove 608, so that the cleaning plate 610 will not contact the protective cover 4. After the first gear 604 is reset, the first guide rod 611 is located at point a. Since the height of the first guide rod 611 in the natural state of the elastic telescopic rod 609 is lower than the height of point d, when the incomplete gear 603 drives the first gear 604 to rotate again, the first guide rod 611 will move to the inner side below the first guide groove 608 to work again. Since the cleaning plate 610 is reset and will not contact the protective cover 4, the protective cover 4 is cleaned unidirectionally, reducing secondary pollution, making the cleaning effect better, and reducing the abnormal situation of street lamp brightness adjustment.

[0038] When the first gear 604 rotates, the torsion spring 606 is energized. When the torsion spring 606 resets, its stored energy is released in a short time, making the reset impact force of the elastic telescopic rod 609 and the cleaning plate 610 larger. The adhesion on the upper part of the cleaning plate 610 can be partially separated under the action of inertia, making the cleaning effect better.

[0039] When the first rotating shaft 601 rotates, it drives the second gear 7101 to rotate, drives the rack 7102 to move upward, drives the second guide rod 7107 to move upward inside the second guide groove 7106. Since the outer vertex at the upper end of the second guide groove 7106 is closer to the linear telescopic rod 7105 than the inner vertex at the upper end of the second guide groove 7106, and the outer vertex at the lower end of the second guide groove 7106 is farther from the linear telescopic rod 7105 than the inner vertex at 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 up and down movement. When the rack 7102 moves up and down, it drives the third guide groove 7204 to perform reciprocating up and down movement. Since the third guide groove 7204 is composed of a plurality of vertical linear grooves connected to arc grooves, and the cooperation mode between the third guide groove 7204 and the third guide rod 7205 is clearance fit, the third guide groove 7204 of the rack 7102 intermittently drives the third guide rod 7205 to perform reciprocating lateral movement. Since the connecting plate 7202 is rotatably connected to the third support plate 7201, the connecting plate 7202 is slidably connected to the second slider 7206, and the connecting mode between the pull rod 7207 and the second slider 7206 is rotatable 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 swings intermittently, improving the wind receiving range of the reversing plate 7203 and enhancing the wind energy utilization efficiency.

[0040] When the reversing plate 7203 swings intermittently, it intercepts the airflow. The airflow will push the reversing plate 7203 to rotate, and its acting force acts from the reversing plate 7203 to the connecting plate 7202, then to the second slider 7206, the pull rod 7207 and the third guide rod 7205, and then to the upper part of the rack 7102, the linear telescopic rod 7105 and the first support plate 3, so that the first support plate 3 rotates, enabling the first support plate 3 to face the airflow in multiple directions to clean the protective cover 4, making the cleaning effect better.

[0041] Since the wind receiving range of the reversing plate 7203 is increased, the wind direction can be changed in time, reducing the possibility that the spoon-shaped blade 602 moves in the reverse direction due to a sudden change in the wind direction, and further reducing the possibility of the cleaning plate 610 moving directly in the reverse direction during the cleaning process, reducing secondary pollution.

[0042] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

The scope of the present invention is defined by the appended claims and their equivalents.
