Double energy-saving street lamps can use solar energy and rainwater to generate electricity, which solves the drawbacks of being unable to rely on solar power due to rainy days. The solar tracking system captures the most favorable angle at any time, improves solar energy utilization, saves resources, protects the environment, and saves energy. The substantial technical characteristics of the row. 1. Double energy-saving street lamp development background Most of the existing street lamps rely on solar panels to generate electricity, which not only uses solar energy, but also cannot generate electricity by itself when it rains. In order to solve these two problems, the double-energy-saving street lamp adds a reflective device to the solar panel, which can reflect the sunlight around the panel in the case of automatically tracking the sunlight, and utilize solar energy more efficiently. . In addition, the street light can collect rainwater as much as possible when it rains, and then it can use rainwater to generate electricity in rainy days. 2. Design and display of double energy-saving street lamps (1) Overall display: a plastic round table reflector, in which a circular battery panel is embedded in the round table reflector, the battery panel is parallel to the bottom surface of the round table reflector, and the front of the panel faces the wide mouth of the round table reflector. Reflective tin foil is attached to the inner wall of the truncated reflective device between the wide mouth of the truncated reflective device and the panel. According to the principle of light reflection, the sunlight irradiated on the inner wall of the reflective reflector can be sufficiently reflected to the panel. At the same time, the device can also collect rainwater, that is, a water tank is arranged at the lower end of the battery board, a water pipeline is connected to the bottom of the water tank, a water wheel and a generator are placed at the bottom of the pipeline, and the gravity force and free fall motion of the rain water are used to drive the power generation. The machine is operated to achieve the function of generating electricity by using rainwater, as shown in Figure 1. figure 1 (2) Electrical control: photosensitive control module stepping motor to realize solar tracking; use rainwater collecting module to control stepping motor to ensure that the battery board can maintain the level when it rains, and collect rainwater to the maximum; photosensitive control module controls the street lamp in the shade It starts automatically when it is dark and dark. (3) Round table reflecting device and rainwater collecting device: the angle between the inclined surface of the round table reflecting device and the plane of the panel is 120 degrees, and the height of the reflecting device is 10 cm, which ensures that the reflected light can shine on the solar energy when the vertical sunlight is irradiated. On the battery board. When there is sunlight, due to the solar tracking system, the sunlight around the solar panel is always reflected to the panel. When it rains, the stepper motor is controlled by the single-chip microcomputer to make the solar round table reflective device horizontally, so that the round table reflective device becomes a rainwater collecting device, and then the rainwater is stored in the water tank, and the potential energy of the rainwater is used to prepare the generator for power generation.
