As shown in FIG. 2 , the automatic light-shielding device 4 is composed of a device casing 41 , a threaded rod 42 , an electromagnet block 43 , and an upper-rotating and shrinking mechanism 44 . And connected by electric welding, the threaded rod 42 is vertically arranged in the middle of the device casing 41 , the electromagnet block 43 is arranged on the upper end of the threaded rod 42 , and the upper-screwing contraction mechanism 44 is sleeved on the outer surface of the threaded rod 42 . And through the meshing and movable connection, the upper-rotation and contraction mechanism 44 is movably connected with the movable lamp bracket 2 through a hinge.

The two sides of the device casing 41 are provided with vertical strip-shaped through slits, and the traction rod of the upper-rotation and contraction mechanism 44 penetrates through the slit and is movably connected with the movable lamp bracket 2 through hinges, so as to realize the sliding of the traction rod and the traction of the movable lamp. The bracket is placed under the solar panel.

The outer surface of the threaded rod 42 is evenly and equally spaced with threads, and the threads and the threaded rod 42 are in an integrated molding structure. Under the action of its own gravity, the light bracket and the street lamp, the up-swinging and retracting mechanism can slowly rotate downward to put down the lamp bracket to ensure its normal operation.

The electromagnet block 43 is electrically connected to the solar panel, so that in sunlight and when the solar panel generates photovoltaic power, the electromagnet block 43 is energized to generate a magnetic attracting and twisting mechanism to provide driving force for the shrinkage of the lamp bracket and the street lamp.

As shown in FIG. 3 , the upper rotation and contraction mechanism 44 is composed of a rotating member 441, a central helical hole 442, a return chute 443, an engaging sliding member 444, and a traction rod 445. The rotating member 441 has a circular structure, The central helical hole 442 is located in the center of the rotating member 441 and is integrally formed. The rotating member 441 is engaged and movably connected to the threaded rod 42 through the central helical hole 442 , and the return chute 443 is provided outside the rotating member 441 The surface is integrally formed. The engaging slide 444 is embedded in the return chute 443 and is slidably connected.

To sum up, the present invention can supply power to the electromagnet block 43 when the sun is shining, that is, when the solar panel can generate photovoltaic power generation, and its energization will generate greater magnetic attraction and upspin. The retracting mechanism 44 rotates upward, and pulls the movable lamp bracket 2 through the traction rod 445 to swing up and retract under the solar panel, so as to prevent the lamp bracket and the street lamp from being exposed to direct sunlight, slow down the aging speed and reduce the cost of road facilities.

The specific realization principle is as follows: when there is sun, that is, when the intensity of sunlight can make the solar panel generate photovoltaic power generation, part of the electric energy generated by the solar panel is supplied to the electromagnet block 43, and the electromagnet block 43 is energized to generate greater magnetic attraction. The iron rotating member 441, the rotating member 441 slowly rotates upward along the threaded rod 42, while the engaging sliding member 444 rotates and rolls relatively along the return chute 443, and the rotating connecting member 444c rotates in the rotating groove 444b to ensure the traction rod. 445 does not affect the rotation of the rotating member 441, and at the same time, one end of the traction rod 445 moves up, and the other end pulls the movable lamp bracket upward and folds and shrinks under the solar panel to prevent the lamp bracket and street lamp from being exposed to direct sunlight and slow down its aging speed; When there is no sun, that is, when it is cloudy and rainy or when it is dark, when the solar panel cannot generate photovoltaic benefits, the electromagnet block 43 is powered off and loses power, and the rotating member 441 slowly rotates downward under the gravity of its own gravity, the lamp bracket and the street lamp. Put the light bracket down to make sure it works properly.

The problem solved by the present invention is that the prior art LED lamp bracket cannot be automatically folded and contracted under the solar panel when there is sunlight, that is, when the solar panel can absorb photovoltaic power generation, resulting in the lamp bracket and the street lamp being exposed to sunlight for a long time. Direct exposure to sunlight can accelerate its aging and increase the cost of road facilities. The present invention combines the above components with each other, and through the automatic light-shielding device provided, when the sun is shining, that is, when the solar panel can generate photovoltaic power, the lamp bracket can be placed on the lamp bracket. The pendulum is retracted under the solar panel to prevent the lamp bracket and street lamp from being exposed to direct sunlight, slowing down its aging speed and reducing the cost of road facilities; when there is no sunlight, slowly lower the lamp bracket to restore the original angle to ensure its normal lighting.
