A solar water heater with protective function for smart home

Abstract

The invention relates to a solar water heater with protective function for smart home, including a base, a processor, a pillar, a plate, a support plate, a water tank, a protective plate, a cleaning mechanism, a rotating mechanism and several vacuum tubes. The cleaning mechanism includes a translation component, Translating block and cleaning assembly, cleaning assembly includes electromagnet, spring, cleaning plate and four orientation units, rotating mechanism includes vertical plate, horizontal plate, rotating box, rotating assembly and pull wire, rotating assembly includes first motor, rotating shaft, casing And wire reel, the solar water heater with protective function for smart home can drive the protective plate to rotate through the rotating mechanism, realize dustproof protection at night, and prevent the vacuum tube from being unable to receive sunlight and heat the water in snowy days Not only that, the dust and debris on the vacuum tube can be removed through the cleaning mechanism, so that the vacuum tube can fully absorb sunlight and improve the efficiency of heating water, thereby improving the practicability of the equipment.

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
