Solar water heater water tank

Abstract

The invention provides a solar water heater water tank. The solar water heater water tank solves the problem that existing water tanks have poor heat preservation effects on rainy and snowy days, andconsequently the service life is shortened due to scouring of rain and snow. An shielding device is arranged on the water tank, the action of shielding the rain and snow can be played for the water tank on the rainy and snowy days, the water tank is prevented from being scoured by the rain and snow, the rain and snow are prevented from accumulating on the water tank, and thus the effect of heat preservation is achieved; the flexibility is greatly improved and practicability is enhanced by the telescopic folding shape of the shielding device, and the shielding device can be unfolded on the rainy and snowy days or folded on a sunny day; a first assembly, a second assembly and a third assembly extend or contract through a driving rod, a main fixing seat and a secondary fixing seat, so as to drive a lifting seat to ascend or descend, unfolding and folding of a waterproof cloth are driven through a telescopic part and a transmission rod; and through a humidity sensor and a programmable logic controller, automatic operation of the shielding device is realized, the degree of automation is increased, and the manpower is saved.

Description

Technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a solar water heater water tank. Background technique [0002] As the world's energy resources become more and more tense, solar energy is more and more widely used. Solar energy is produced by the hydrogen nuclear fusion of the hydrogen atoms in the sun to release huge nuclear energy. Solar energy is a new type of renewable energy. Energy and solar energy can be used in two ways: photothermal conversion and photoelectric conversion. Currently, the technology of photothermal conversion is the most mature, such as solar water heaters. [0003] Solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet people's hot water use in life and production. Solar water heaters usually include water storage tanks and heat collectors. The water tank is a device used in solar concentrated hot ...

AI Technical Summary

Problems solved by technology

However, in the weather of hail, rain and snow, the heat preservation effect of the existing water tank is obviously reduced, and the service life of the water tank is also reduced due to the erosion of rain, snow and hail.
