Description

A photovoltaic panel angle-adjustable solar street light

Technical Field

The invention relates to the technical field of solar street lamps, and in particular to a solar street lamp with adjustable photovoltaic panel angle.

Background technique

As traditional energy sources become increasingly scarce, solar energy is increasingly being used, especially in the field of solar power generation, which has developed into a mature and promising industry in just a few years. At the same time, with the development and progress of solar photovoltaic technology, the dual advantages of solar lighting products in environmental protection and energy saving, the application of solar street lights has gradually become large-scale;

Solar street lights rely on photovoltaic panels to generate electricity and store it in batteries as one of the energy sources for street lights. Generally speaking, the best direction for the photovoltaic panel surface is due south, and the peak time of solar radiation energy is after noon, which means that when the sun shines on the photovoltaic panel surface at a vertical angle of 90 degrees from 12 noon to 1 o'clock, it is the peak time for photovoltaic panels to generate electricity. If the photovoltaic panel is deviated 30 degrees east or west from due south, the power generation of the photovoltaic panel will be reduced by 10% to 20% accordingly; the power generation of photovoltaic panels in different longitude and latitude regions and different seasons will have certain differences.

The photovoltaic panels of existing solar street lights are mostly set at a fixed angle. In order to make the photovoltaic panels face due south, the orientation of the street lights is often adjusted by crane and manual work during the installation of solar street lights. This adjustment method is time-consuming and labor-intensive, and often cannot make the photovoltaic panels face due south accurately. In addition, since the sunshine angles in different regions and seasons are different, the fixed photovoltaic panels cannot be adjusted in angle. In addition, the photovoltaic panels cannot face due south during installation, which greatly reduces the utilization rate of solar energy by solar panels.

When the lamp post 1 of the solar street lamp is installed, the adjusting screw 12 is rotated clockwise, and the adjusting screw 12 gradually moves upward, so that the angle between the photovoltaic panel 6 and the ground gradually increases. As the adjusting screw 12 rises, the unlocking mechanism gradually abuts against the locking mechanism. When the end of the thread groove at the bottom of the adjusting screw 12 abuts against the ratchet 13, the unlocking mechanism completely separates the locking mechanism from the ratchet 13. At this time, the angle between the photovoltaic panel 6 and the horizontal plane is the largest. At this time, the adjusting screw 12 continues to be rotated clockwise, and the adjusting screw 12 will drive the ratchet 13 to rotate together, and the support plate 22 is driven to rotate through the two synchronous arc plates 21, thereby driving The photovoltaic panel 6 is movable to rotate clockwise around the adjusting screw 12, so that the orientation of the photovoltaic panel 6 can be easily adjusted and the photovoltaic panel 6 can be accurately oriented to the south. After the orientation of the photovoltaic panel 6 is adjusted, the adjusting screw 12 is rotated counterclockwise. At this time, the adjusting screw 12 moves downward through the ratchet 13 threadedly connected to it. During the downward movement of the adjusting screw 12, the locking mechanism fixes the ratchet 13 again. At this time, the adjusting screw 12 continues to be rotated counterclockwise, and the adjusting screw 12 continues to move downward, so that the inclination angle of the photovoltaic panel 6 can be reduced to an appropriate range, thereby making the photovoltaic panel 6 face the sunlight, which greatly improves the power generation efficiency of the photovoltaic panel 6.

Furthermore, a plurality of positioning holes 14 are provided on the ratchet 13, and the locking mechanism includes two fixed blocks 15 fixedly arranged on the inner wall of the fixed cylinder 3, and a positioning rod 16 adapted to the positioning hole 14 is slidably arranged on each fixed block 15, and a top plate 161 is fixedly arranged at one end of each positioning rod 16 close to the photovoltaic panel 6, and springs 17 are fixedly arranged one by one between each top plate 161 and each fixed block 15; in the initial state, each positioning rod 16 is inserted into the positioning hole 14 of the ratchet 13 by the elastic force of the spring 17, and the ratchet 13 is in a fixed state at this time, so that the adjusting screw 12 can move upward when it rotates clockwise.

As the adjusting screw 12 moves upward, the push rods 19 push out the two positioning rods 16 in the positioning hole 14. At this time, the end of the thread groove of the adjusting screw 12 moves to the ratchet 13, and the adjusting screw 12 continues to be rotated clockwise, and the ratchet 13 rotates with the adjusting screw 12.

Specifically, two fixing frames 42 are fixedly arranged in the fixing cylinder 3, and a limit plate 41 is rotatably arranged in each fixing frame 42, and a torsion spring 43 is fixedly arranged between each limit plate 41 and each fixing frame 42 in a one-to-one correspondence, and an abutment plate 44 is fixedly arranged on the side wall of each fixing frame 42; a plurality of ratchet teeth are arranged on the outer peripheral surface of the ratchet wheel 13, and the two fixing frames 42 are fixedly arranged in the annular groove 301, and when the ratchet wheel 13 rotates clockwise with the adjusting screw 12, each limit plate 41 is squeezed to make each The limit plate 41 rotates, so that the ratchet 13 rotates normally with the adjusting screw 12. When the adjusting screw 12 rotates counterclockwise, the limit plate 41 cannot rotate through the abutment plate 44, and the ratchet teeth on the ratchet 13 can only rotate clockwise but not counterclockwise, so that the adjusting screw 12 moves downward when rotating counterclockwise, and then each push rod 19 can be smoothly moved out of the positioning hole 14, so that the positioning rod 16 falls into the positioning hole 14 again to fix the ratchet 13.
