Description

Technical Field

[0001] The present invention relates to the field of lighting technology, specifically to the field of street lamp technology, and in particular to an energy-saving smart lighting street lamp. Background Art

[0002] Based on the green environmental protection concept, more and more public facilities are beginning to use green energy, such as street lights, and more use of photovoltaic power generation or wind power generation to reduce carbon emissions and reduce the pollution of traditional energy to the environment.

[0003] Based on wind power generation, some existing technologies have been found after searching, and they are introduced one by one:

[0004] First, the Chinese invention patent with publication number CN1916395A discloses a comprehensive multifunctional wind-powered street lamp, which uses the power of wind to drive the air compressor through a wind propeller to compress the air. The compressed air is provided to the compressed air power generation unit at night to generate electricity, thereby providing electricity for the street lamp lighting unit, realizing clean and pollution-free natural energy to provide street lamp lighting.

[0005] Secondly, the Chinese invention patent with authorization announcement number CN105627241B discloses an air energy storage photovoltaic LED street light system and control method, which uses photovoltaic power generation from solar panels to provide power for an air compressor, which runs to generate and store compressed air. At night, the compressed air is used to drive a wind turbine to generate electricity, thereby providing power for the street light lighting unit.

[0006] Both of the above solutions generate and store compressed air, generate electricity through compressed air, and provide electricity for street lighting. However, they both have some shortcomings. Air compression storage has a storage limit. When the storage space is full of compressed air, whether it is photovoltaic power generation or wind propeller-driven air compressor, it cannot continue to compress and store air. That is, after the compressed air is full, the energy supplied to the air compressor will be wasted. In addition, the night is long and street lights need to be illuminated for nearly half a day. It is difficult to maintain wind power generation for such a long time simply relying on stored compressed air.

[0007] Based on the above, the present invention proposes an energy-saving smart lighting street lamp. Summary of the invention

[0008] In order to solve the problems mentioned in the above background, the present invention provides an energy-saving smart lighting street lamp.

[0017] As a further improvement and optimization of the present invention, a spring is provided between the bracket and the mounting frame, and the elastic force of the spring is used to drive the bracket to move away from the generator 2.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This solution can not only use external wind power to generate compressed air, but also use wind power to generate electricity and store it when the compressed air is full, so that wind energy will not be wasted.

DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0031] In this solution, wind power generation is mainly adopted, and photovoltaic power generation is supplemented, so the purpose of energy saving can be achieved. In addition, in this solution, it can automatically switch to power storage after the compressed air is full, without wasting energy. The automatic switching method does not require human participation and is more intelligent.

[0032] This solution is suitable for environments with abundant wind resources, such as islands, coastal cities, etc.

[0033] Reference Figure 1-Figure 8 An energy-saving smart lighting street lamp includes a base 100 fixed to the ground, and a vertically arranged lamp post 101 is arranged on the upper end surface of the base 100. The interior of the lamp post 101 is hollow and used to store compressed air. An upper mounting shell 102 is arranged at the upper end of the lamp post 101, and a lamp unit 103 of the street lamp is connected to the outer surface of the upper mounting shell 102. Furthermore, a photovoltaic panel is arranged on the upper surface of the lamp unit 103 for photovoltaic power generation.

[0034] The upper end surface of the upper mounting shell 102 is provided with vertically arranged blades 104 , and the bottom of the blades 104 extends into the upper mounting shell 102 . When wind blows, the blades 104 can be rotated by the wind.

[0035] An air compressor 105, an air motor 106, a generator 107 and a generator 2 108 are arranged in the upper mounting shell 102, wherein a drive assembly 200 is arranged between the blades 104, the air compressor 105 and the generator 2 108, and the drive assembly 200 is configured to switch between a transfer state 1 and a transfer state 2.

[0036] Initially, the driving assembly 200 is in the transmission state 1. When the blades 104 are rotated by the wind, the rotational motion is transmitted to the air compressor 105 through the driving assembly 200 in the transmission state 1, so that the air compressor 105 is operated. The generated compressed air is stored in the lamp post 101. When night falls, the valve on the connecting pipe between the lamp post 101 and the air motor 106 is opened, and the air motor 106 is driven to operate by the compressed air. The air motor 106 is connected to the generator 107, so that the generator 107 can be driven to operate, and the generated electricity is sent to the lamp unit 103.

[0037] When the lamp post 101 is full of compressed air, the drive component 200 will automatically switch to the transfer state 2, and the rotation of the blade 104 will be transmitted to the generator 2 108 by the drive component 200 in the transfer state 2 to make it run. The generated electricity will be stored in the battery. When the compressed air is used up and the external wind is weak and cannot provide new compressed air in time, the battery can be used as a backup power supply to power the lamp unit 103.

[0038] Reference Figure 3-Figure 8 The driving assembly 200 includes a mounting frame arranged in the upper mounting shell 102, and a differential 201 and a planetary reducer 202 are installed on the mounting frame. Both of them can be realized by existing technologies and are not described in detail.

[0039] The differential 201 includes an input shaft 2013 , an output half shaft 1 2011 and an output half shaft 2 2012 . The input shaft 2013 is dynamically connected to the blade 104 , and the output half shaft 2012 is dynamically connected to the air compressor 105 via the planetary reducer 202 .

[0040] The output half shaft 1 2011 and the generator 2 108 are connected in power via a connecting component.

[0041] Further, see Figure 6The generator 2 108 is coaxial with the output half shaft 1 2011, and there is a connecting sleeve shaft 203 and a limiting sleeve 204 between the two. The connecting sleeve shaft 203 and the limiting sleeve 204 are both cylindrical with openings at both ends, and are coaxial with the output half shaft 1 2011, wherein the limiting sleeve 204 is fixed on the mounting frame. Initially, the connecting sleeve shaft 203 is arranged in the limiting sleeve 204 through a spline coaxial sleeve, and the end of the output half shaft 1 2011 is also arranged in the connecting sleeve shaft 203 through a spline coaxial sleeve. In addition, the connecting sleeve shaft 203 and the generator 2 The output shafts of 108 can also be connected by splines, but initially, the connecting sleeve shaft 203 and the generator 2 108 are not connected. Therefore, initially, the limit sleeve 204 limits the rotation of the connecting sleeve shaft 203, thereby limiting the rotation of the output half shaft 1 2011. Based on the working principle of the differential 201, the power brought by the rotation of the blade 104 is completely transmitted to the air compressor 105 through the output half shaft 2 2012 of the differential 201 and the planetary reducer 202, and the drive assembly 200 is in the transmission state one.

[0042] Reference Figure 7 and Figure 8 The outside of the connecting sleeve shaft 203 is connected with a bracket 205 .

[0043] A cover 207 is installed on the mounting frame, and a piston 209 is sleeved in the cover 207. The sliding direction of the piston 209 is parallel to the axial direction of the connecting sleeve shaft 203. A connecting rod 210 extends from the end of the piston 209. The end of the connecting rod 210 extends out of the cover 207 and is connected to the bracket 205. The cover 207 and the lamp post 101 are connected through the air pipe 208.

[0044] A spring 206 is arranged between the bracket 205 and the mounting frame, and the elastic force of the spring 206 is used to drive the bracket 205 to move away from the generator 108; when the air compressor 105 is running, the compressed air is stored in the lamp post 101. During this process, since the cover 207 and the lamp post 101 are connected, as the air pressure in the lamp post 101 increases, it will gradually overcome the elastic force of the spring 206 and drive the piston 209 to move, thereby driving the bracket 205 to move closer to the generator 108, and the bracket 205 moves with the connecting sleeve shaft 203. When the lamp post 101 is full of compressed air, the connecting sleeve shaft 203 is simultaneously sleeved between the generator 108 and the output half shaft 1 2011, and is separated from the limit sleeve 204. Therefore, based on the working principle of the differential 201, the power brought by the rotation of the blade 104 is completely transmitted to the generator 108 through the output half shaft 1 2011 and the connecting sleeve shaft 203 of the differential 201.

[0045] Working principle of the present invention:

[0046] First, the driving assembly 200 is in the transmission state 1, and the limit sleeve 204 limits the rotation of the connecting sleeve shaft 203, thereby limiting the rotation of the output half shaft 1 2011. Based on the working principle of the differential 201, the power brought by the rotation of the blade 104 is fully transmitted to the air compressor 105 through the output half shaft 2 2012 of the differential 201 and the planetary reducer 202, so that it can run, and the generated compressed air is stored in the lamp post 101. When night falls, the valve on the connecting pipe between the lamp post 101 and the pneumatic motor 106 is opened, and the pneumatic motor 106 is driven to run by compressed air. The pneumatic motor 106 is connected to the generator 107, so it can drive the generator 107 to run, and the generated electricity is sent to the lamp unit 103;

[0047] Secondly, during the process of storing compressed air in the lamp post 101, since the cover 207 is connected to the lamp post 101, as the air pressure in the lamp post 101 increases, it will gradually overcome the elastic force of the spring 206 and drive the piston 209 to move, thereby driving the bracket 205 to move closer to the generator 2 108, and the bracket 205 moves with the connecting sleeve shaft 203. When the lamp post 101 is full of compressed air, the connecting sleeve shaft 203 is simultaneously sleeved between the generator 2 108 and the output half shaft 1 2011, and is separated from the limit sleeve 204, and the drive assembly 200 switches to the transmission state 2. Based on the working principle of the differential 201, the power brought by the rotation of the blade 104 is fully transmitted to the generator 2 108 through the output half shaft 1 2011 and the connecting sleeve shaft 203 of the differential 201, so that it runs, and the generated electricity is stored in the battery;

[0048] When the compressed air in the lamp post 101 is used, the air pressure in the lamp post 101 decreases, and the spring 206 releases its elastic force, thereby switching the drive assembly 200 to the transmission state one.

[0049] From the above, we can know that:

[0050] This solution can not only use external wind power to generate compressed air, but also use wind power to generate electricity and store it when the compressed air is full, so that wind energy will not be wasted. On this basis: in this solution, as a driving component for power connection between generator 2, air compressor and blades, it can transfer all the power brought by the rotating action of the blades, that is, the power brought by the external wind, to the air compressor when the compressed air is not full, so as to ensure the storage of compressed air, so that at night, the compressed air drives the pneumatic motor and generator 1 to operate and provide power for the lighting unit. This process is not affected, and when the compressed air is full, the power brought by the external wind can be transferred to generator 2. The electricity generated by generator 2 can be stored in the battery as a backup power supply, and the utilization rate of external wind energy is higher.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
