Embodiment

[0046] 1. The pulley assembly 5 can be replaced by a gear assembly of the same size, and the placement position and specific operation mode can be referred to the pulley assembly.

[0047] 2. If Figure 8a , Figure 8b , Figure 8c As shown, the heat collecting pipe 6 can be replaced by a heat pipe group, and the tap water in the water storage tank 7 is rapidly heated by using the heat pipe to transfer heat quickly. Wherein part of the heat pipe group in the water storage tank 7 is the condensation end, and the part in the thermal insulation frame is the evaporation end. When the evaporating end receives the heat emitted by the solar photovoltaic 18 panel, the liquid in the heat pipe evaporates rapidly, and the steam flows to the condensing end under a small pressure difference, and releases heat to heat the water in the water storage tank, and then condenses in the heat pipe group The liquid flows back to the evaporating end by the action of capillary force, so that the re...

Abstract

The invention provides a self-cleaning solar photovoltaic heat collection system based on the hydrophobicity of lotus leaves. The self-cleaning solar photovoltaic heat collection system based on the hydrophobicity of lotus leaves comprises a solar photovoltaic heat collection system body and an automatic cleaning system. The self-cleaning solar photovoltaic heat collection system based on the hydrophobicity of lotus leaves has the effects that the functions of power generation, heat collection, automatic cleaning and the like are achieved, automatic cleaning can be achieved through devices such as a pulley assembly and a spraying pipe according to the hydrophobicity principle of lotus leaves, and the utilization rate of solar energy is increased. Power stored in a solar photovoltaic panelis supplied to electric equipment such as a driving motor, a water pump and a controller, and thus no extra power supply is needed. A control hub is mounted in the system, and thus manual control canbe achieved in certain emergencies. Hot water and electricity used in the cleaning process are all supplied by the system, and thus the self-cleaning solar photovoltaic heat collection system based onthe hydrophobicity of lotus leaves accords with the concept of environmental friendliness, energy saving and sustainability.

Description

technical field [0001] The invention belongs to the field of building energy saving and renewable energy utilization, focusing on the technical field of solar photovoltaic heat collection, specifically a self-cleaning solar photovoltaic heat collection system based on the principle of lotus leaf hydrophobicity. Background technique [0002] With the advent of the energy crisis in the world today, human beings pay more and more attention to renewable energy such as solar energy, so how to improve the utilization rate of solar energy has become a primary issue. In real life, a layer of dust will accumulate on the surface of solar photovoltaic panels, which will reduce the utilization rate of solar energy. Most of the dust removal tools of the current automatic dust removal system use soft brushes. The disadvantage is that the cleaning efficiency will decrease with time, it cannot work in rainy days, and it will inevitably leave scratches on the surface of the photovoltaic pane...
