By adopting the technical scheme, the tubular motor, the electric push rod, the miniature motor speed reducer and the lamp are all connected with the controller through the power supply control line. The solar cell panel is micro-light, and can perform photoelectric conversion operation under the condition of weak sunlight, so that the photoelectric efficiency is greatly improved.
The sunlight tracking sensor provides sunlight tracking sensing signals for the controller, the controller sends starting signals to the electric push rod and the micro motor speed reducer, the output shaft of the micro motor speed reducer drives the upper rotary table to rotate, and the supporting balls at the bottom of the upper rotary table roll in the circular groove, so that the sunlight tracking sensor has good supporting and friction force reducing effects. The outer sleeve which is fixedly integrated with the upper rotary table synchronously rotates on the outer tube of the lamp post, the effect that the upper rotary table can only rotate is achieved, the mounting box and the support which are fixedly arranged at the tops of the outer sleeve and the upper rotary table also synchronously rotate, so that the solar cell panel is driven to rotate, meanwhile, the electric push rod stretches or shortens, the solar cell panel is driven to conduct inclination angle adjustment by taking the two first hinges as supporting points, and under the combined action of the electric push rod and the miniature motor speed reducer, the surface of the solar cell panel can be kept perpendicular to solar rays, and therefore photoelectric conversion efficiency is further improved.

When the solar panel runs for a period of time, such as one month, dust is attached to the surface of the transparent PVC film above the solar panel, even bird droppings are arranged, the light transmittance is reduced, a controller sends an instruction to a tubular motor, the tubular motor is started to pull the transparent PVC film upwards to be wound on an upper winding drum through an upper guide roller, the transparent PVC film wound on a lower winding drum is moved to the surface of the solar panel through a lower guide roller, the transparent PVC film only needing to update the surface of the solar panel is adopted, the solar panel is not required to be cleaned, and after snow falls in winter, if snow covers the surface of the transparent PVC film, the tubular motor can be started to pull the transparent PVC film upwards to update the transparent PVC film on the surface of the solar panel in order to improve the power generation efficiency. The torsion spring plays a role in enabling the transparent PVC film to be in a certain tension state, ensures that the transparent PVC film is unfolded on the surface of the solar cell panel, and also prevents the transparent PVC film from being blown up by wind power. The transparent PVC film and the solar cell panel are contacted with each other, and the surface of the transparent PVC film and the surface of the solar cell panel are uniformly provided with a plurality of dot particles, so that the transparent PVC film and the surface of the solar cell panel can be prevented from being completely attached, and a ventilation gap is formed between the transparent PVC film and the solar cell panel, so that the transparent PVC film can be updated and moved conveniently, and the tensile force of the tubular motor is reduced. The cover shell plays a role in avoiding the transparent PVC film wound on the winding drum under the irradiation of sunlight and also avoids the transparent PVC film from adhering dust before being paved on the solar cell panel. The PVC material has good high temperature resistance and ageing resistance, the thickness of the transparent PVC film can be 1-3mm, and the transparent PVC film has good toughness.
When the transparent PVC film wound on the lower winding drum is used up, street lamp maintenance personnel replace the new transparent PVC film through a street lamp maintenance vehicle (a lifting platform vehicle or an overhead working vehicle), and the transparent PVC film on the upper winding drum is pulled out downwards or cut off directly. And then taking down the limiting snap spring and the torsion spring, drawing out the central shaft, taking out the lower winding drum from the housing, placing a new transparent PVC film wound on the lower winding drum in advance into the housing, penetrating the central shaft, installing the torsion spring and the limiting snap spring, pulling out the transparent PVC film from the long hole, bypassing the lower guide roller and the upper guide roller, and fixing the transparent PVC film on the upper winding drum.
When the lamp is installed, after three lower fixing blocks at the top of the lamp are basically corresponding to three upper fixing blocks on the lower surface of the upper fixing plate, the horizontal part of the T-shaped block stretches into the insertion port, the horizontal part of the T-shaped block stretches into the rectangular blind hole, the lower surface of the upper contact fixing block contacts with the upper surface of the lower fixing block, then the lamp is horizontally pushed or pulled, the vertical part of the T-shaped block moves to the other end of the guide hole along the guide hole, meanwhile, the horizontal part of the T-shaped block moves along the rectangular blind hole, at the moment, the upper fixing block and the lower fixing block are correspondingly flush up and down, the limiting plate which is horizontally arranged rotates upwards by 90 degrees by taking the screw as the center, the upper part of the limiting plate contacts with the side surface of the upper fixing block, and finally the screw is screwed by using a spanner or a screw driver, so that the upper fixing block and the lower fixing block are positioned.
The lamp and the cantilever rod adopt a push-pull type connecting structure, are positioned through the rotary limiting plate, are convenient and quick to install, and when the lamp is required to be disassembled, the limiting plate is rotated for 90 degrees to be in a horizontal state, and the upper part of the limiting plate is not contacted with the side surface of the upper fixing block. And then the lamp is horizontally moved, and when the horizontal part of the T-shaped block is moved to the inserting port, the lamp is downwards moved, so that the lamp can be separated from the cantilever. The lamp adopts an LED lamp, so that the brightness is high, and the energy-saving effect is good.
Because fifth through wires hole and fourth through wires hole have been seted up respectively to the top of mounting box top and lamps and lanterns, in order to avoid the rainwater of raining to enter into the through wires hole, set up waterproof seal structure in the upper portion of through wires hole, the upper port of external screw thread boss is higher than mounting box top surface and lamps and lanterns top surface to set up the sealing cap, the sealing cap has the elasticity effect, plays the fastening seal effect to the line of penetrating, just so plays good rain-proof effect.
In conclusion, the solar panel angle adjusting device is scientific in principle, compact in structure and convenient to install, and the angle of the solar panel is adjusted, so that the solar panel can be kept in a state perpendicular to sunlight, and the solar energy utilization efficiency is improved to the greatest extent. Meanwhile, a new mode is provided for cleaning the solar cell panel, and the surface film is coated and the set time is updated, so that the photoelectric conversion efficiency of the solar cell panel is improved; in addition, a lamp structure convenient to install and detach is provided, so that the installation efficiency is improved.
