Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and in particular to a wind energy and light energy complementary street lamp lighting system. Background Art

[0002] Street lights refer to lamps that provide lighting for roads. They generally refer to lamps within the scope of road lighting in traffic lighting. Street lights are widely used in various places where lighting is needed. Street lights are generally connected to the mains, but with the application and popularization of LEDs, the lighting power is reduced while the lighting brightness is consistent. At the same time, the use of photovoltaic panels has greatly reduced the electricity cost of street lights.

[0003] Most of the existing street lamps are equipped with photovoltaic panels, and some are equipped with wind power generation equipment based on the photovoltaic panels. However, the photovoltaic panels and wind power generation equipment are set separately, which is not conducive to improving the aesthetics of the street lamps. In addition, the power generation equipment on the street lamps is basically fixed and cannot be changed in space. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a wind-solar complementary street lighting system, including a lamp pole, the upper end of which is sleeved with a Y-shaped bracket, a driving motor fixedly connected to the interior of the lamp pole, the output end of the driving motor is vertically arranged, and the output end of the driving motor is fixedly connected to the bottom of the Y-shaped bracket, a lamp is fixedly connected to one end of the upper part of the Y-shaped bracket, and a power generation unit is fixedly connected to the other end of the upper end of the Y-shaped bracket. Starting the driving motor and controlling the rotation of the Y-shaped bracket is more conducive to the power generation of the power generation unit. When lighting is performed at night, the driving motor is started again to reset the Y-shaped bracket.

[0005] The power generation unit includes a support tube, the side wall of the support tube is fixedly connected with a plurality of iron cores, the side wall of the iron core is provided with a groove, and the cross-sectional shape of the iron core is an "I" shape, a coil is wound in the groove, the outer side of the iron core is rotatably connected with a rotating drum, the inner wall of the rotating drum is fixedly connected with a plurality of bar-shaped permanent magnets at equal angles, a plurality of blades are provided on the outer side of the rotating drum, the outer surface of the blades is provided with a photovoltaic panel, the inner wall of the blades is fixedly connected with a second connecting rod, and the other end of the second connecting rod is fixedly connected to the side wall of the rotating drum. The blades rotate under the blowing of the airflow, so that the coil cuts the magnetic field excited by the permanent magnet, thereby generating electricity. At the same time, under sufficient sunlight and in coordination with the angle of the drive motor, photovoltaic power generation with maximum efficiency can be achieved, that is, simultaneous power generation of wind energy and light energy can be achieved.

[0006] In addition, the matching mode of the iron core and the coil, as well as the fixation of the iron core and the support tube, greatly reduce the difficulty of production. At the same time, the longer size is conducive to reducing the diameter of the drum.

[0007] Preferably, the lower end of the lamp pole is fixedly connected to a base, and the upper end of the Y-shaped bracket is fixedly connected to an arc-shaped first connecting rod. The first connecting rod and the base both ensure the stability of the street lamp. Preferably, one end of the support tube is fixedly connected with a flange, and a flange is also provided at the upper end between the Y-shapes, that is, the power generation unit is fixed by means of a flange connection.

[0008] Preferably, the side wall of the support tube is fixedly connected with a bearing, and the outer ring of the bearing is matched with the inner part of the rotating drum. Note that bearings are arranged at both ends of the rotating drum.

[0009] Preferably, both ends of the support tube are fixedly connected with a fixing rod, and the other end of the fixing rod is provided with a brush roller for wiping the surface of the blade. During the rotation of the blade, the brush roller removes stains on the surface of the blade, ensuring the cleanliness of the surface of the blade, which is conducive to improving the efficiency of photovoltaic power generation.

[0010] Preferably, a rotating shaft extends from both ends of the brush roller, and the rotating shaft is slidably matched with a long hole preset at the end of the fixed rod. A cylindrical shell is provided at the end of the rotating shaft, and an electromagnet is fixedly connected to the fixed rod, and the output end of the electromagnet that remains extended is fixedly connected to the side wall of the shell. When the surface of the blade needs to be cleaned, the electromagnet is energized, the output end of the electromagnet retracts, the brush roller contacts the surface of the blade, and the brush roller cleans the surface of the blade during the rotation of the blade.

[0011] Preferably, a circular ring is provided inside the shell, and the circular ring is fixedly connected to the rotating shaft, a spring is radially provided inside the shell, one end of the spring is against a steel ball, and the steel ball fits in a groove preset in the side wall of the circular ring. In the cleaning process, to avoid synchronous rotation of the brush roller and the blades, which makes the cleaning effect of the brush roller unsatisfactory, springs, steel balls, etc. are provided to realize segmented rotation of the brush roller. During cleaning, dust on the blades will gather at the contact part between the brush roller and the blades. When the friction force generated between the brush roller and the blades is greater than the resistance generated by the springs, steel balls, etc., the brush roller is forced to rotate, so that the brush roller and the blades without dust are in contact.

[0012] Preferably, a partition is provided between adjacent coils to improve the electrical performance between the coils.

[0013] The beneficial effects of the present invention are as follows: 1. A Y-shaped bracket is provided, and one side of the upper end of the Y-shaped bracket is a lamp, and the other side is a power generation unit. At the same time, a driving motor is provided on the lamp pole to drive the Y-shaped bracket to rotate, which can not only improve the efficiency of the power generation unit, but also ensure the overall aesthetics of the street lamp.

[0014] 2. The power generation unit integrates photovoltaic power generation and wind power generation, and multiple iron cores can be independently installed on the support tube. This structure is not only conducive to the winding of the coil, but also conducive to disassembly and assembly, reducing the difficulty of production. The iron core, coil, and permanent magnet constitute the main part of the wind power generation. This part is attached to the support tube, which can increase the axial length while reducing the radial size, which is conducive to improving the appearance of the street lamp.

[0015] 3. A brush roller is provided, which can contact the blades under the action of the electromagnet. During the rotation of the blades, the outer surface of the blades can be wiped and cleaned to improve the efficiency of the photovoltaic panel.

[0016] 4. A shell, a spring, a steel ball and a circular ring are arranged at the end of the rotating shaft. Under the action of the spring, the steel ball presses against the preset groove on the side wall of the circular ring, so that there is resistance to the rotation of the rotating shaft. When the friction force between the brush roller and the blades caused by dust is greater than the above resistance, the brush roller can be forced to rotate, ensuring that the brush roller will not rotate at will and ensuring the cleaning effect.

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1 to 5 As shown, a wind-solar complementary street lamp lighting system includes a lamp pole 2, which is a round tube. A Y-shaped bracket 3 is sleeved on the upper end of the lamp pole 2. In order to improve the aesthetics of the street lamp, the diameter of the Y-shaped bracket 3 is gradually reduced from the lower end to the upper end. A driving motor is fixedly connected to the inside of the lamp pole 2. The output end of the driving motor is vertically arranged, and the output end of the driving motor is fixedly connected to the bottom of the Y-shaped bracket 3. That is, the driving motor is started to rotate the Y-shaped bracket 3. A lamp 6 is fixedly connected to one end of the upper part of the Y-shaped bracket 3 for road lighting. The other end of the upper end of the Y-shaped bracket 3 is fixedly connected to a power generation unit 4, which is a device for converting light energy and wind energy into electrical energy. At the same time, during the rotation of the Y-shaped bracket 3, the position of the power generation unit 4 also changes accordingly, which is beneficial to the power generation of the power generation unit 4. When lighting is performed, the driving motor works to reset the Y-shaped bracket 3.

[0021] The power generation unit 4 includes a support tube 44, which is a pipe with a circular cross-section. A plurality of iron cores 411 are fixedly connected to the side wall of the support tube 44, that is, all the iron cores 411 are fixed around the side wall of the support tube 44, and the side wall of the iron core 411 is provided with a groove, and the cross-sectional shape of the iron core 411 is an "I" shape, and a coil 412 is wound in the groove. The structure of the iron core 411 is conducive to the winding of the coil 412. At the same time, the independent design of the iron core 411 can realize the disassembly and assembly of a single iron core 411 at the upper end of the support tube 44, which is conducive to improving production efficiency. At the same time, this design can greatly increase the length of the iron core 411. The outer side of the iron core 411 is rotatably connected to a rotating drum 45, and the inner wall of the rotating drum 45 is fixedly connected with a plurality of bar-shaped permanent magnets 48 at equal angles. As the rotating drum 45 rotates, the permanent magnets 48 cut the coil 412 Magnetic field, thereby generating electric current. A plurality of blades 41 are arranged on the outside of the rotating drum 45, that is, under the action of wind force, the blades 41 push the rotating drum 45 to rotate. It should be noted that the type of wind turbine used here is a vertical axis wind turbine. Since the vertical axis wind turbine is not affected by the wind direction, in this scheme, tilting it will not affect the efficiency of power generation. A photovoltaic panel 42 is arranged on the outer surface of the blade 41, that is, when there is sufficient sunshine, the photovoltaic panel 42 also generates electricity. However, the height of the sun is different at different times, which seriously affects the power generation of the photovoltaic panel 42. Therefore, the position of the power generation unit 4 can be changed by driving the motor, so as to maximize the power generation efficiency of the photovoltaic panel 42. The inner wall of the blade 41 is fixedly connected with a second connecting rod 410, and the other end of the second connecting rod 410 is fixedly connected to the side wall of the rotating drum 45.

[0022] The lower end of the lamp pole 2 is fixedly connected to the base 1, and a charging and discharging module and a battery are arranged inside the base 1 to store the electric energy generated by the power generation unit 4. The upper end of the Y-shaped bracket 3 is fixedly connected to the arc-shaped first connecting rod 5, and the first connecting rod 5 and the base 1 are both used to improve the overall structural strength of the street lamp.

[0023] One end of the support tube 44 is fixedly connected to a flange 43 , that is, the power generation unit 43 is fixedly connected to the Y-shaped bracket 3 through a plurality of bolts passing through preset through holes on the flange 43 .

[0024] A bearing 49 is fixedly connected to the side wall of the support tube 44. The outer ring of the bearing 49 fits with the interior of the rotating drum 45. Two bearings 49 are provided here, respectively located at the two ends of the rotating drum 45, to reduce the rotational resistance of the rotating drum 45. At the same time, O-rings are provided at both ends of the rotating drum 45.

[0025] Both ends of the support tube 44 are fixedly connected with fixing rods 47, and the fixing rods 47 are bent to avoid blocking the blades 41. The other end of the fixing rod 47 is provided with a brush roller 46 for wiping the surface of the blade 41. During the rotation of the blade 41, the brush roller 46 contacts the surface of the blade 41 to clean the surface of the blade 41, thereby improving the power generation efficiency of the photovoltaic panel 42.

[0026] A rotating shaft 417 is extended from both ends of the brush roller 46, and the rotating shaft 417 is slidably fitted in a long hole preset at the end of the fixed rod 47, and the long hole is set to extend radially about the rotating drum 45, that is, the brush roller 46 can move away from and close to the blade 41, and a cylindrical shell 414 is provided at the end of the rotating shaft 417, and an electromagnet 415 is fixedly connected to the fixed rod 47. The output end of the electromagnet 415 is maintained in an extended state and is fixedly connected to the side wall of the shell 414. When the blade is cleaned, the electromagnet 415 is started, its output end is retracted, and the shell 414 is pulled, so that the brush roller 46 and the outer side of the blade 41 are in contact.

[0027] A circular ring 418 is provided inside the shell 414, and the circular ring 418 is fixedly connected to the rotating shaft 417. A spring 416 is radially provided inside the shell 414, and one end of the spring 416 is against a steel ball 419. The steel ball 419 fits in a groove preset on the side wall of the circular ring 418, and a plurality of grooves are provided at equal angles on the side wall of the circular ring 418. Under the action of the spring 416, the steel ball 419 fits in the groove, so that the rotation of the brush roller 46 has a sense of segmentation. That is, during the cleaning process, if a large amount of dust will accumulate between the contact between the brush roller 46 and the blade 41, if the friction force produced is greater than the resistance generated by the spring 416, the steel ball 419, etc., the brush roller 46 will rotate, so that the dust-free brush roller 46 and the blade 41 will contact, thereby improving the cleaning effect.

[0028] A partition 413 is provided between adjacent coils 412 to prevent the adjacent coils 412 from being damaged or short-circuited due to friction.

[0029] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
