Solar water heater with protection and adjustment functions

Abstract

The invention relates to a solar water heater with protection and adjustment functions. The solar water heater comprises a base, a support, a transverse plate, a flat plate, a processor, a water tank,an adjusting mechanism, a protection mechanism and a plurality of vacuum pipes, wherein the protection mechanism comprises a protection cover and a light reflecting assembly arranged in the protection cover; and the adjusting mechanism comprises an adjusting box, a rotating shaft, a rotating assembly, a rotating plate, a telescopic assembly, a connecting block and two connecting rods. According to the solar water heater with the protection and adjustment functions, the vacuum pipes can be protected through the protection mechanism when rainfall or snowfall occurs, and the situation that accumulated snow or rainfall falls on the vacuum pipes, and consequently equipment operation is affected is avoided; and in addition, the angle position of the protection cover can be adjusted through theadjusting mechanism, a translation unit is matched to drive a translation block to move, the angle of a light reflecting plate is changed, the light reflecting plate can reflect sunlight to irradiatethe vacuum pipes when the sunlight irradiates from the side close to the water tank, the sunlight radiation quantity absorbed by the vacuum pipes and the heating effect on water are guaranteed, and therefore the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a solar water heater with protection and adjustment functions. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. [0003] However, in the existing solar water heaters, the vacuum tubes are fixed and exposed on the water heaters. On the one hand, after rain or snowfall occurs in winter, the snow o...

Problems solved by technology

[0003] However, in the existing solar water heaters, the vacuum tubes are fixed and exposed on the water heaters. On the one hand, after rain or snowfall occurs in winter, the snow or rainwater hits the surface of the vacuum tubes, which is easy to freeze into ice, which affects the absorption of sunlight by the vacuum tubes. In severe cases, due to snow The form of water frozen into ice changes, which damages the vacuum tube. At the same time, because the vacuum tube is fixedly installed, the direction of sunlight propagation changes with time. When the sunlight no longer shines on the vacuum tube, the heat absorption efficiency of the vacuum tube is likely to decrease. And then reduce the warming effect to water, cause the practicability of existing solar water heater to reduce
