Abstract
The utility model discloses an orientation regulation and cooling integrated device for a photovoltaic pump solar panel. The device comprises the solar panel, cooling pipelines, a ratchet wheel, a pawl, a support, a supporting shaft, a lower shaft, light dependent resistors, an electromagnetism slide valve, a water pump and a water storage tank. The cooling pipelines are symmetrically laid on the back surface of the solar panel, the solar panel is fixed to the supporting shaft which can rotate around the axis of the support, the ratchet wheel and the pawl are installed between the solar panel and the support, and the light dependent resistors are symmetrically pasted on the surface of the solar panel. The water pump is driven by power generated in a photovoltaic mode to pump water, and the pumped water passes through the cooling pipelines to cool the solar panel. The light dependent resistors detect the illumination incidence. The potential difference regulates a valve core of the electromagnetism slide valve to move axially. The flow of the two symmetrical sides of the solar panel is controlled by inlets of the cooling pipelines through the electromagnetism slide valve. When flows of the cooling pipelines on the two sides are not equal, the solar panel inclines towards the side with larger flow under the supporting of the support and the action of gravity, the pawl rotates, and the orientation of the solar panel changes so that the solar panel can face to the direct lighting direction. By employing a fluid cooling gravity lever method, integration of cooling and orientation changing for the solar panel is achieved, so that the photovoltaic power generation efficiency is improved, and the service lifetime of the solar panel is prolonged.
