[0002] Solar energy refers to the thermal radiation energy of the sun, which is mainly manifested in the so-called sunlight. It is a renewable resource and is generally used to generate electricity or provide energy for water heaters in modern times. Its technology is very mature.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] See also Figure 1-Figure 4 The energy-saving lighting device based on solar energy includes a landscape lamp body 1, which includes a lamp post 2. The upper wall of the lamp post 2 is connected to an LED lamp head 24 through a connecting rod 23. A control box 3 is fixedly installed on the top of the lamp post 2. The control box 3 includes a box body 31. The central part of the bottom surface of the box body 31 is rotatably connected to a rotating shaft 32, and the top of the rotating shaft 32 passes through the top surface of the box body 31. A U-shaped frame 4 is fixedly arranged on the top of the rotating shaft 32. An L-shaped connecting rod 33 is welded on the part of the rotating shaft 32 passing through the top surface of the box body 31 and the wall surface in the vertical direction of the U-shaped frame 4. An electric push rod 5 is fixedly connected to the top surface of one end of the L-shaped connecting rod 33 away from the rotating shaft 32. A photovoltaic module 7 is rotatably connected between the two vertical sections of the U-shaped frame 4. The top of the electric push rod 5 is hinged to the photovoltaic module 7 through a rotating component 6, and a light tracking device 8 is fixedly installed on the top surface of the photovoltaic module 7.

[0032] In this embodiment, the bottom of the lamp post 2 is integrally formed with a fixed base 21 extending outward, and each corner of the fixed base 21 is provided with a bolt hole 211 for fixing to the ground by bolts. The upper end wall of the lamp post 2 is located below the connecting rod 23 and is provided with an infrared sensor 22 for sensing pedestrians and vehicles. When the landscape lamp body 1 is installed at a specified position, it can be fixed by bolts passing through the bolt holes 211. When pedestrians or vehicles pass by, the infrared sensor 22 sends a signal to the PLC controller 37, and the PLC controller 37 starts its own timing switch program. The energy storage battery 38 transmits current to the LED lamp head 24 through the wire. When there are no pedestrians or vehicles passing by, the infrared sensor 22 does not work, and the timing switch program of the PLC controller 37 is in a closed state, thereby saving energy.

[0033] In this embodiment, a reset rotating motor 36 is installed on one side of the rotating shaft 32 inside the box 31. The rotating shaft 32 is located at the upper end of the box 31 and is fixedly sleeved with a transmission gear 34. The output shaft of the reset rotating motor 36 is coaxially sleeved with a driving gear 35. The transmission gear 34 and the driving gear 35 are located at the same horizontal height and are meshed with each other. The bottom surface of the reset rotating motor 36 is fixedly installed on the bottom surface of the box 31 by bolts. During a clear day, the reset rotating motor, under the action of the light tracking device 8, will cause the photovoltaic component 7 to rotate with the change of the angle of sunlight, that is, to make a semicircular motion from east to west. At night, the reset rotating motor 36 controls the photovoltaic component 7 to return along the original rotation path through the implanted special chip, that is, to make a semicircular motion from west to east, in preparation for welcoming the sunlight of the next day. In this way, solar energy can be collected more efficiently and the wires inside the box 31 can be effectively prevented from being entangled with each other.

[0034] In addition, a PLC controller 37 and an energy storage battery 38 are fixedly installed inside the box 31. When the solar photovoltaic panel 72 converts the collected solar energy into electrical energy and stores the electrical energy in the energy storage battery 38 through electrical connection, the PLC controller 37 can receive signals from the infrared sensor 22 and the light tracker 8, and then issue an instruction to reset the rotating motor 36 to allow the entire device system to work normally.

[0035] In this embodiment, two symmetrical pins 41 are detachably installed at the upper ends of the two vertical sections of the U-shaped frame 4. The pins 41 pass through the corresponding vertical sections of the U-shaped frame 4 and are plugged into the photovoltaic component 7. The reason for adopting the rotating plug-in method is to enable the photovoltaic component 7 to rotate as the angle of sunlight changes. At the same time, the electric push rod 5 can also rotate in a vertical angle to follow the light through the telescopic change, so as to receive sunlight in a wider range.

[0036] In order to realize the vertical rotation of the above-mentioned photovoltaic component 7, it is also necessary to supplement that the rotating component 6 includes a fixed block 61 welded and fixed on the top surface of the electric push rod 5, and the fixed block 61 is hinged with a sliding block 62 through a pin shaft. The top of the sliding block 62 is slidably connected to the bottom surface of the photovoltaic component 7. The rotating component 6 realizes the vertical rotation of the photovoltaic component 7 through the electric push rod 5 fixedly connected thereto under the action of the reset rotating motor 36. It should be noted that the fixed block 61 does not contact the bottom surface of the photovoltaic component 7, the sliding block 62 does not contact the top surface of the electric push rod 5, or the upper end of the fixed block 61 and the lower end of the sliding block 62 are both convex arc structures, thereby ensuring that the photovoltaic component 7 can rotate smoothly at a vertical angle.

[0037] The photovoltaic assembly includes a mounting plate 71 with a groove on the top surface, and a solar photovoltaic panel 72 is embedded in the groove of the mounting plate 71.

[0038] In this embodiment, the infrared sensor 22, the LED lamp head 24, the reset rotating motor 36, the PLC controller 37, the solar photovoltaic panel 72, the electric push rod 5 and the light tracker 8 are electrically connected to the energy storage battery 38 through wires, and the infrared sensor 22, the LED lamp head 24, the reset rotating motor 36, the electric push rod 5 and the light tracker 8 are signal-connected to the PLC controller 37 through signal lines, so that each component in the entire device can be electrically connected or signal-connected accordingly, each performing its own function to ensure the normal operation of the device.

[0039] Finally, it should be noted that the infrared sensor 22, LED lamp head 24, reset rotating motor 36, PLC controller 37, energy storage battery 38, solar photovoltaic panel 72, electric push rod 5 and light tracker 8 involved in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In an environment where the device needs to be installed, the above-mentioned device is fixed to the ground with bolts. The corresponding working procedures between each component should refer to the working principle of the device. The electrical connection and signal connection between the components are completed in a certain working order, and the detailed connection means are all well-known technologies in the field.

[0040] Working principle: When the energy-saving lighting device based on solar energy of this embodiment is working, the light tracker 8 arranged on the top surface of the photovoltaic module 7 sends a corresponding signal to the PLC controller 37 according to the change of the irradiation angle of the sunlight, and the PLC controller 37 sends a command to the reset rotating motor 36. The reset rotating motor 36 is electrically connected to the energy storage battery 38 through a wire. After the reset rotating motor 36 is turned on, it drives the rotating shaft 32 on the top surface fixed with the U-shaped frame 4 to rotate through the driving gear 35 and the transmission gear 34, thereby driving the photovoltaic module 7 rotatably connected to the U-shaped frame 4 to rotate with the change of the irradiation angle of the sunlight, thereby realizing the collection of solar energy from a wider range at all times, and converting a larger amount of solar energy into electrical energy and storing it in the energy storage battery 38 through electrical connection;

[0041] In addition, the electric push rod 5 will also be compressed or stretched according to the change of the sunlight angle sensed by the PLC controller 37 under the action of the reset rotating motor 36, and at the same time, the photovoltaic component 7 is rotated vertically by the auxiliary action of the rotating component 6, thereby further realizing the collection of solar energy in a wider range;

[0042] The collected solar energy is converted into electrical energy through the solar photovoltaic panel 72, and the electrical energy is stored in the energy storage battery 38 through an electrically connected wire. The electrical energy in the energy storage battery 38 is transmitted through the electrically connected PLC controller 37. When the timing switch program in the PLC controller 37 reaches the set time, when the infrared sensor 22 sends a signal that a pedestrian or a vehicle is passing, the timing switch program is turned on, and the electrical energy stored in the energy storage battery 38 is sent to the LED lamp head 24 electrically connected to the energy storage battery 38, so that the LED light source can work normally. When the pedestrian or vehicle leaves the range that the infrared sensor 22 can perceive, the timing switch program is in a closed state, thereby saving electricity.

Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
