DETAILED DESCRIPTION

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Embodiment: A LED municipal street lamp with a photovoltaic panel assembly, such as Figure 1-Figure 5As shown, it includes a base 1, a lamp post 2, a lamp body 3, an electric push rod 4, a pushing rod 5, a lifting rod 7, a photovoltaic panel 8 and a battery 9. The lamp post 2 is welded on the top of the base 1, the lamp body 3 is fixedly installed on the upper part of the lamp post 2, the electric push rod 4 is rotatably installed in the middle of the lamp post 2, the pushing rod of the electric push rod 4 is welded with a pushing rod 5, the upper part of the pushing rod 5 is rotatably connected to the lifting rod 7, the top of the lifting rod 7 is fixedly connected to the photovoltaic panel 8 by means of bolts, the bottom of the photovoltaic panel 8 is fixedly installed by means of bolts, the photovoltaic panel 8 generates electricity through sunlight and stores electrical energy in the battery 9, and the battery 9 can supply power to the lamp body 3 and the electric push rod 4.

[0036] like Figure 4 As shown, a servo motor 6 is also included. The servo motor 6 is fixedly installed on the upper part of the push rod 5 by means of bolts. The output shaft of the servo motor 6 is fixedly connected to the lower part of the lifting rod 7. The battery 9 can supply power to the servo motor 6.

[0037] When the street lamp is in use, the lamp post 2 and the lamp body 3 can be installed on the street or road that needs lighting through the base 1. After installation, it is connected to the municipal street lamp management system through the power system, so that light can be brought to the road conveniently and efficiently.

[0038] After the street lamp is installed, when there is sufficient sunlight, the photovoltaic panel 8 can generate electricity through sunlight and store the electrical energy in the battery 9. In this way, at night, the battery 9 can supply power to the lamp body 3 to improve the utilization efficiency of new energy.

[0039] If the street lamp is installed next to a roadside tree, the branches or leaves of the roadside tree that grow high can easily block the photovoltaic panel 8 from absorbing sunlight, affecting the power generation efficiency of the photovoltaic panel 8. At this time, the electric push rod 4 can be started to drive the push rod 5 and the lifting rod 7 to move upward, so that the photovoltaic panel 8 and the battery 9 can be moved upward to avoid the photovoltaic panel 8 being blocked. At night, the electric push rod 4 can be started to drive the push rod 5 and the lifting rod 7 to move down and retract to reset, so as to avoid the stability of the photovoltaic panel 8 being affected by strong wind at night.

[0040] When the electric push rod 4 pushes the photovoltaic panel 8 and the battery 9 to move up to the limit, if the photovoltaic panel 8 is still blocked, the servo motor 6 can be started, and the output shaft of the servo motor 6 drives the lifting rod 7 to rotate, and then the lifting rod 7 drives the photovoltaic panel 8 and the battery 9 to rotate, so that different angles can be selected according to the blocking situation to ensure that the photovoltaic panel 8 can absorb sunlight.

[0041] like Figure 5-Figure 7As shown, it also includes a fixing ring 101, a gas tank 102, a piston rod 103, a connecting piece 104, a return spring 105, an air pipe 106, a one-way valve 107 and a nozzle 108. A fixing ring 101 is welded on the top of the lamp post 2, and the gas tanks 102 are fixedly connected to the front and rear sides of the upper part of the lifting rod 7. The piston rods 103 are slidably connected inside the two gas tanks 102. Each piston rod 103 extends upward from the corresponding gas tank 102, and a return spring is fixedly connected between each piston rod 103 and the corresponding gas tank 102. 105. The bottom of each piston rod 103 is connected to a connector 104 by bolts. The left side of each gas storage tank 102 is fixedly connected and connected to a gas pipe 106. A one-way valve 107 is fixedly installed on the left side of each gas pipe 106. A nozzle 108 is fixedly installed on the upper end of each gas pipe 106. The outlet of each nozzle 108 is aligned with the upper surface of the photovoltaic panel 8. Each nozzle 108 is fixedly connected to the left side of the photovoltaic panel 8. The piston rod 103 is in sealing contact with the gas storage tank 102 to ensure that the gas in the gas storage tank 102 can be pushed out.

[0042] When the photovoltaic panel 8 and the battery 9 are pushed upward by the electric push rod 4, the photovoltaic panel 8 drives the gas tank 102 to move upward. Initially, the reset spring 105 is in a stretched state. As the gas tank 102 moves upward, the reset spring 105 gradually resets, and then the reset spring 105 pulls the piston rod 103 to move downward relative to the gas tank 102, so that the piston rod 103 will push the air inside the gas tank 102 to flow along the gas pipe 106 to the nozzle 108, and the air is quickly ejected from the nozzle 108, and the nozzle 108 outlet is aimed at the upper surface of the photovoltaic panel 8, so that the gas ejected from the nozzle 108 will wash the upper surface of the photovoltaic panel 8, and blow off impurities such as leaves and dust that fall from the upper surface of the photovoltaic panel 8, so as to avoid the accumulation of impurities on the photovoltaic panel 8 and affect the power generation efficiency of the photovoltaic panel 8. As the gas tank 102 continues to rise, the connecting piece 104 will no longer be connected with the fixing ring 1 01, and the air inside the gas tank 102 will also be completely squeezed out by the squeezing action of the piston rod 103, and when the photovoltaic panel 8 and the battery 9 are driven downward by the electric push rod 4, the photovoltaic panel 8 drives the gas tank 102 to move downward, and when the gas tank 102 moves down to near the initial position, the connecting piece 104 will contact the fixing ring 101 again, and as the gas tank 102 continues to move downward, the connecting piece 104 will be pushed by the fixing ring 101 to move upward relative to the gas tank 102, at this time, the return spring 105 is stretched, and the piston rod 103 also gradually moves toward the outside of the gas tank 102, so that the piston rod 103 will infuse new air into the gas tank 102 through the gas pipe 106 and the one-way valve 107, so that under the action of the gas pipe 106 and the nozzle 108, the upper surface of the photovoltaic panel 8 can be effectively blown and washed to avoid affecting the power generation efficiency of the photovoltaic panel 8.

[0043] like Figure 8-Figure 10As shown in the figure, it further includes a shielding plate 111, a connecting block 112, a pulling rope 113 and a limiting block 114. The shielding plates 111 are rotatably connected to the front and rear sides of the photovoltaic panel 8. Connecting blocks 112 are fixedly connected to the tops of the two shielding plates 111. A plurality of limiting blocks 114 are fixedly connected to the side and bottom of the photovoltaic panel 8. Pulling ropes 113 are fixedly connected between the connecting blocks 112 and the corresponding connecting members 104. Each pulling rope 113 is restricted to the bottom of the photovoltaic panel 8 by the limiting block 114 on the same side.

[0044] When the piston rod 103 moves downward relative to the gas storage tank 102, the piston rod 103 drives the connecting member 104 to move downward relative to the photovoltaic panel 8. At this time, the connecting member 104 pulls the pulling rope 113 downward, and the pulling rope 113 will pull the shielding plate 111 on the same side to rotate and open along the front and rear sides of the photovoltaic panel 8. In this way, the branches and leaves on the front and rear sides of the photovoltaic panel 8 can be pushed away, so as to prevent the photovoltaic panel 8 from being blocked. And the shielding plates 111 are closed and covered above the photovoltaic panel 8, which can greatly improve the safety of the photovoltaic panel 8 at night. When in use, start the electric push rod 4 to push the photovoltaic panel 8 upward to open the shielding plate 111. When the piston rod 103 moves upward relative to the gas storage tank 102, the connecting member 104 will gradually release the tension of the pulling rope 113, and the shielding plate 111 will gradually reverse and reset under the action of gravity.

[0045] As Figure 11-13 As shown in the figure, it further includes a cylinder body 121, a piston member 122, a protection plate 123, a cylinder body 124, an extrusion rod 125, a connecting pipe 126, a return spring 127 and a top block 128. The cylinder bodies 121 are fixedly connected to the front and rear sides of the bottom of the photovoltaic panel 8. The piston members 122 are slidably connected to the left and right sides inside each cylinder body 121. A protection plate 123 is fixedly connected between the two piston members 122 on the left side by bolts. A protection plate 123 is also fixedly connected between the two piston members 122 on the right side by bolts. The two protection plates 123 are located on the left and right sides of the photovoltaic panel 8. Each cylinder body 121 is fixedly connected and communicated with a connecting pipe 126 at the bottom. The other ends of the two connecting pipes 126 are fixedly connected and communicated with a cylinder body 124. The extrusion rods 125 are slidably connected inside the cylinder bodies 124. A return spring 127 is connected between each extrusion rod 125 and the corresponding cylinder body 124. Top blocks 128 are fixedly connected to the mutually separated sides of the two connecting members 104. The tops of the two top blocks 128 are in contact with the extrusion rods 125 on the same side. The cylinder bodies 121, the cylinder bodies 124 and the connecting pipes 126 are all filled with hydraulic oil. The piston members 122 are in sealed contact with the cylinder bodies 121. The extrusion rods 125 are in sealed contact with the cylinder bodies 124.

[0046] Initially, the return spring 127 is in a stretched state. When the piston rod 103 and the connecting piece 104 move downward relative to the gas tank 102, the top block 128 also moves downward relative to the gas tank 102, so that the top block 128 will gradually reduce the top force on the extrusion rod 125, and the extrusion rod 125 will slide into the inside of the second cylinder 124 under the reset action of the return spring 127. In this way, the extrusion rod 125 squeezes the hydraulic oil in the inside of the second cylinder 124 to flow into the inside of the first cylinder 121 along the connecting pipe 126, and the hydraulic oil in the first cylinder 121 pushes the pistons 122 on both sides to move outward, and the protective plate 123 moves to the side away from the photovoltaic panel 8 under the drive of the piston 122 on the same side, so that the protective plate 123 can be automatically moved when the photovoltaic panel 8 moves upward. The guard plate 123 opens outward to push away the branches and leaves on the left and right sides of the photovoltaic panel 8 to ensure sufficient exposure to sunlight above the photovoltaic panel 8. When the photovoltaic panel 8 moves downward, the top block 128 will gradually push the extrusion rod 125 to slide upward inside the cylinder body 124. At this time, the return spring 127 is stretched, and the extrusion rod 125 will also draw the hydraulic oil inside the cylinder body 121 along the connecting pipe 126 into the cylinder body 124. In this way, the pistons 122 on both sides of the cylinder body 121 will also gradually retract into the cylinder body 121, and the guard plate 123 will also gradually move to the initial position. At this point, under the action of the guard plate 123, the photovoltaic panel 8 can be effectively prevented from being blocked by the branches or leaves on the left and right sides, ensuring the effective power generation of the photovoltaic panel 8.

[0047] like Fig.14 and Fig.15 As shown, it also includes a worm 131, a connecting rod 132 and a turbine 133. The worm 131 is rotatably connected to the right side of the lower part of the lamp post 2, the connecting rod 132 is fixedly connected to the bottom of the electric push rod 4, and the turbine 133 is fixedly connected to the bottom of the connecting rod 132. The turbine 133 is meshed with the worm 131.

[0048] When the photovoltaic panel 8 generates electricity through solar energy, in order to improve the accuracy of the photovoltaic panel 8 being exposed to sunlight, the photovoltaic panel 8 is pushed up by the electric push rod 4 to avoid being blocked. If the photovoltaic panel 8 is still blocked after being raised, the servo motor 6 can be started to adjust the three-dimensional angle of the lifting rod 7 and the photovoltaic panel 8. At the same time, according to the on-site situation, the worm 131 can be rotated to drive the turbine 133 and the connecting rod 132 to rotate, thereby driving the electric push rod 4, the lifting rod 7 and the photovoltaic panel 8 to rotate, so as to adjust the plane angle of the photovoltaic panel 8. At this point, the height, three-dimensional angle and plane angle of the photovoltaic panel 8 can be adjusted through a variety of adjustment methods to ensure that the street lamp can effectively generate electricity through the photovoltaic panel 8 during the day, thereby improving the utilization efficiency of new energy.

[0049] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
