Adjustable solar street lamp

Abstract

The invention belongs to the field of solar lighting, and concretely relates to an adjustable solar street lamp, which comprises a base under an earth surface, and a support fixedly arranged on the base. A transparent semicircular ball cavity is fixedly arranged on the top part of the support; water is filled in the ball cavity; a solar energy storage plate for receiving solar energy is further connected to the top part of a vertical rod; a wind shielding barrel fixedly arranged on the support is further arranged outside the ball cavity; a baffle ring for separating a placed floating ball is arranged on an opening of the ball cavity; a water pump is arranged on an outer wall of the ball cavity; a support rod fixedly arranged on the support is arranged under the ball cavity; a lighting lampelectrically connected with the solar energy storage plate is arranged on the end part of the support rod; a pipeline connected with an external water source is arranged in the support; the bottom part of the water pump communicates with the pipeline; and a water pipe connecting into the ball cavity is arranged on the top part of the water pump. According to the adjustable solar street lamp provided by the invention, a direction or a position of the solar energy storage plate is adjusted, so that solar energy can be efficiently utilized through the solar energy storage plate.

Description

technical field [0001] The invention belongs to the field of solar lighting, and in particular relates to an adjustable solar street lamp. Background technique [0002] Solar street lights are composed of solar panels that use sunlight to generate electricity and batteries that store electricity generated by solar cells, solar panels that are powered by solar panels to emit light, and supporting solar panels, batteries, and lighting It consists of the pillars of the device. The solar street lamp constructed in this way stores the electricity generated by the solar cell in the battery, and then supplies the electricity from the battery to the lighting device, thereby driving the lighting device. Solar street lights use sunlight to generate electricity during the day, and then send the generated electricity to the battery. The electricity stored in the storage battery is supplied to the lighting device at night. Therefore, since the lamp of the lighting device emits light a...

Problems solved by technology

[0003] The problem with the existing solar street lights is that most of the current solar street lights are installed outdoors, and the angle of the sun’s light will change with time. When the sun is incident vertically at noon in a day, the solar storage panels can maximize Limit the absorption of light energy, but in the morning and evening, the sunlight is not vertically incident and there is an angle with the solar storage panel, and because the position of the solar storage panel is fixed, the sunlight changes all the time, which leads to The solar storage panels cannot exert maximum efficiency to absorb the energy of sunlight, resulting in low luminous intensity of solar street lights and low energy utilization rate.
