Solar water heater with protection function for home automation

Abstract

The invention relates to a solar water heater with a protection function for home automation. The solar water heater comprises a base, a processor, a support post, a flat plate, a support plate, a water tank, a protection plate, a cleaning mechanism, a rotating mechanism and a plurality of vacuum tubes. The cleaning mechanism comprises a translation assembly, a translation block and a cleaning assembly, wherein the cleaning assembly comprises an electromagnet, a spring, a cleaning plate and four directional units. The rotating mechanism comprises a vertical plate, a transverse plate, a rotating box, a rotating assembly and a pull wire, wherein the rotating assembly comprises a first motor, a rotating shaft, a sleeve pipe and a wire coil. According to the solar water heater with the protection function for home automation, the rotating mechanism drives the protection plate to rotate, so that at night dust-proof protection can be realized, and in snowy days the situation that the vacuumtubes can not absorb sunlight because of being accumulated with snow so as to fail to heat water can be avoided; and in addition, through the cleaning mechanism, dust and sundries on the vacuum tubescan be cleaned out, which is convenient for the vacuum tubes to fully absorb sunlight, in this way, the water heating efficiency is improved, and the usability of the device is further increased.

Description

technical field [0001] The invention relates to the field of solar photovoltaic applications, in particular to a solar water heater with protection function for smart homes. 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] Existing solar water heaters passively receive sunlight during use, and convert all received solar energy into thermal energy for heating water. Therefore, in sunn...

Problems solved by technology

[0003] Existing solar water heaters passively receive sunlight during use, and convert all received solar energy into thermal energy for heating water. Therefore, in sunny weather, especially in sunny days in summer, The water temperature in the water tank of the solar water heater can quickly reach a higher temperature. At this time, when the user is on a business trip or traveling, the water heater will not produce water for a long time, so that the water tank is in a state of high temperature and high pressure for a long time, which will promote the aging of the sealing ring. , Accelerate the aging and shrinkage of polyurethane, and sometimes the exhaust is not smooth, and the pressure is too high, which will cause the water tank to swell, scale, and shorten the life of the water tank. After snowing in winter, snow covers the surface of the vacuum tube, blocking The transmission of sunlight makes it impossible to heat the water flow in the vacuum tube. Not only that, but in the existing solar water heaters, the vacuum tube is exposed to the outside for a long time, and it is easy to accumulate dust. The dust in the air is adsorbed on the surface of the vacuum tube, so that the vacuum tube cannot fully absorb the sun. light, which directly leads to the reduction of heating efficiency of existing solar water heaters
