Detailed ways

In order to describe in detail the technical content, the achieved purpose and the effect of the present application, the following description will be given in conjunction with the embodiments and the accompanying drawings.

The traditional solar power generation device adjusts the angle of solar panels and stores them through multiple sets of adjustment mechanisms, which improves the solar energy acquisition rate to a certain extent, but its structure is complicated and its working stability cannot be guaranteed.

The most critical idea of the present application is to realize the storage, deployment and angle adjustment of the photovoltaic panel by rotating the flip seat. Further angle adjustment is performed by rotating the photovoltaic panel. Obtain the accurate sunlight position through the information interaction function of the smart street lamp. The structure is simple to ensure the maximum solar energy harvest rate.

Please refer to FIG. 1 to FIG. 6, which is an embodiment of this application. A smart street light 1 in which a solar power generation component 2 is installed on the top of the smart street light 1. A storage battery 12 and a main control board 11 are installed in the equipment compartment of the smart street light 1, and the storage battery 12 is electrically connected to the main control board 11. The solar power assembly 2 includes a main body 21, a flip seat 23 and a photovoltaic panel 24. One end of the flip seat 23 is rotatably connected to the main body 21. Such a solar power generation module has a simple structure. Specifically, the main body 21 is a regular prism. The turning seat 23 is located on the side of the main body 21 and is connected with the main body 21 through a hinge. The photovoltaic panel 24 is rotatably connected to the flip seat 23. The main body 21 is provided with a first turning mechanism 22 connected to the turning base 23, and the first turning mechanism 22 is used to control the turning base 23 to be deployed, stored and angularly deflected on the main body 21. The turning base 23 is provided with a second turning mechanism connected to the photovoltaic panel 24. The second turning mechanism is used to control the angle deflection of the photovoltaic panel 24 on the turning seat 23. 4 and 5, the flip seat 23 is provided with an altitude sensor 234 for monitoring the angular position of the flip seat 23, and the photovoltaic panel 24 is provided with an azimuth sensor 241 for detecting the angular position of the photovoltaic panel 24. The height angle sensor 234, the azimuth angle sensor 241, the first turning mechanism 22, the second turning mechanism and the photovoltaic panel 24 are electrically connected to the main control board 11, respectively. In this way, a complete set of automatic sunlight following system can be formed by combining the above-mentioned structure, and the automatic sunlight following system adopts the sun-based motion trajectory tracking method. Since the trajectory of the vertical projection of sunlight on the ground has a functional relationship with time, latitude and longitude, the azimuth and altitude angle of sunlight can be calculated as long as the latitude and longitude and time of the location where the sunlight follows the system is known. The latitude, longitude and time of the smart street light 1 can be obtained by using the GPS and networking functions of the smart street light 1. The main control board 11 calculates the current azimuth and altitude angle of the sunlight and the best deflection angle of the photovoltaic panel 24 through the sunlight projection function, and Compare with the angles fed back by the altitude angle sensor 234 and the azimuth angle sensor 241. After that, a current signal is output to drive the first turning mechanism 22 and the second turning mechanism to adjust the photovoltaic panel 24 to a proper position, so that the photovoltaic panel 24 is perpendicular to the sunlight at all times, and the maximum light energy acquisition rate is obtained. Since this automatic sunlight following system does not use sunlight intensity conversion as the basis for angle adjustment, it is not affected by bad weather and has strong structural stability.

The storage state of the smart street light 1 means that all the photovoltaic panels 24 in the solar power generation module 2 are vertical to the ground, and the system does not generate electricity at this time. The unfolded state is a normal working state, that is, the photovoltaic panel 24 is unfolded to obtain sunlight, and the angle is adjusted to follow the sunlight to achieve the purpose of vertical sunlight. When the smart street light 1 is in the storage state, the system will automatically turn off the sun light auto-following system, and automatically turn on the sun light auto-following system when it is deployed.

Optionally, the main body 21 is a regular prism, and at least one side surface of the main body 21 is connected with a turning seat 23. In other words, the main body 21 may be a regular triangular prism, a regular quadrangular prism, a regular pentagonal prism, or the like. The setting of the specific edge number can be set reasonably according to actual application requirements.

In this embodiment, the main body 21 is a regular quadrangular prism body, and the four sides of the main body 21 are respectively provided with turning seats 23, and the turning seats 23 are respectively connected with the main body 21 through two hinges. Correspondingly, the four sides of the main body 21 are respectively provided with installation grooves 211 for installing the first turning mechanism 22. The first turning mechanism 22 includes a pitch motor 222 and a ball screw device installed in the installation slot 211, and also includes a support rod 225. One end of the support rod 225 is rotatably connected with the ball screw device, and the other end is rotatably connected with the turning seat 23. The ball screw device includes a screw 221, a sliding block 223, a connection base 224, and a coupling 227. The lead screw 221 is rotatably arranged on the connecting base 224. The slider 223 is provided with an internal thread, the screw 221 is provided with an external thread that fits with the internal thread of the slider 223, and the slider 223 and the screw 221 are connected by threading. A pitch motor 222 is installed at one end of the connection base 224. The output shaft of the pitch motor 222 is connected to the lead screw 221 through a coupling 227. The rotation of the pitch motor 222 can drive the lead screw 221 to rotate. The sliding block 223 can convert the rotary motion of the lead screw 221 into a linear reciprocating motion. The sliding block 223 is provided with a hinge support 226, and the support rod 225 is hinged with the hinge support 226 through rivets. When the pitch motor 222 rotates, the screw 221 is driven to rotate, and the rotation of the screw 221 can drive the sliding block 223 to make a vertical movement, thereby pushing the flip seat 23 to rotate around the hinge through the support rod 225 to complete the storage and unfolding of the flip seat 23. And the angle adjustment in the unfolded state.

An installation cavity 231 for installing the photovoltaic panel 24 is opened on the side of the flip seat 23 close to the photovoltaic panel 24. The second turning mechanism includes a rotating shaft 232 rotatably disposed in the mounting cavity 231 and a horizontal motor 233, and the horizontal motor 233 is used to drive the rotating shaft 232 to rotate. Specifically, two ends of the rotating shaft 232 are respectively connected with a bearing 235, and are connected to the turning seat 23 through the bearing 235. A gear 236 is also provided on the rotating shaft 232 and meshes with the gear 236 at the output end of the horizontal motor 233. Two supporting seats 242 are installed on the back of the photovoltaic panel 24, and the photovoltaic panel 24 is fixedly connected to the rotating shaft 232 through the two supporting seats 242. When the horizontal motor 233 rotates, it will drive the gear 236 on the rotating shaft 232 to rotate, thereby driving the photovoltaic panel 24 to rotate so as to complete the angle adjustment of the photovoltaic panel 24 on the turning seat 23. In addition, a hinge support 226 is installed at the bottom of the flip seat 23, and the hinge support 226 is hinged with the support rod 225 by rivets.

In one or more of the embodiments, a weather sensor 25 is installed on the top of the main body 21. It is easy to understand that the weather sensor 25 can monitor light, wind speed and other information at any time. When the light intensity is lower than the preset value or the wind speed is greater than the preset value, the weather sensor 25 will transmit the signal to the main control board 11 in time. The main control board 11 issues instructions to drive the horizontal motor 233 and the tilt motor 222 to rotate, so that the photovoltaic panel 24 is transformed from the unfolded state to the stored state, and at the same time, the automatic sunlight following system is turned off. Similarly, when the light intensity is greater than the preset value and the wind speed is less than the preset value, the horizontal motor 233 and the tilt motor 222 are driven to convert the photovoltaic panel 24 from the storage state to the unfolded state. When unfolding, the automatic sunlight following system is turned on to make the photovoltaic panel 24 Vertical to the sun.

The working principle of the smart street lamp 1 in this embodiment is: as the sun rises, the intensity of the sun's light gradually increases. When the light intensity received by the weather sensor 25 is greater than the system preset value, a signal is sent to the main control board 11. After the main control board 11 receives the signal, it starts the automatic sunlight following system, calculates the azimuth and altitude of the sunlight at this time, and compares it with the angle of the photovoltaic panel 24 fed back by the azimuth sensor 241 and the altitude sensor 234 to drive The horizontal motor 233 and the tilt motor 222 make a rotating movement, so that the four photovoltaic panels 24 are moved from being stored to unfolded, and the angles are adjusted respectively, so that the four photovoltaic panels 24 are perpendicular to the sunlight.

Over time, the sun will continue to drift. Similarly, the main control board 11 continuously corrects the azimuth and altitude of the sunlight according to time, and continuously drives the horizontal motor 233 and the pitch motor 222 to adjust the angle of the photovoltaic panel 24, so that the photovoltaic panel 24 is always vertical to the sunlight until the sun sets. . When the light intensity is less than the preset value of the system, the main control board 11 receives the signal of the weather sensor 25, drives the horizontal motor 233 and the tilt motor 222, so that the photovoltaic panel 24 is converted from the unfolded state to the stored state, and the automatic sunlight following system is turned off . In this way, the smart street light 1 will go back and forth as the sun rises from the east to the west, and goes from storage to expansion to storage.

When the smart street light 1 is in the unfolded state, if it encounters strong wind or rainy weather with insufficient light, the weather sensor 25 will immediately send a signal to the main control board 11, and the main control board 11 drives the tilt motor 222 and the horizontal motor 233, and the photovoltaic panel 24 storage, and turn off the sun's automatic follow system. Until the weather returns to normal, it will start again, and the automatic sunlight following system will be turned on to make the solar photovoltaic panel 24 perpendicular to the sunlight again.

In addition, when the photovoltaic panel 24 is unfolded to storage, dust and snow accumulated on the surface of the photovoltaic panel 24 will also fall, and the rain will also wash the surface of the photovoltaic panel 24 in the storage state, which has a cleaning effect.
