The invention relates to a
solar water heater with cleaning and protection functions. The
solar water heater comprises a base, a water tank, a supporting plate, a supporting column, a connection box and multiple heat collection pipes and further comprises a
protection mechanism and a cleaning mechanism. The
protection mechanism comprises a supporting shaft, a hinge rod, a baffle, a slide block anda lifting
assembly, the cleansing mechanism comprises a driving
assembly and multiple cleaning assemblies, and each cleaning
assembly comprises a gear, a bearing, a cleaning plate, a connection rod,two supporting rods, two connection rings and two connection units. According to the
solar water heater with the cleaning and protection functions, through the
protection mechanism, the heat collection pipes and the water tank can be shielded, and the situation is avoided that due to rainwater
corrosion, normal work of the solar
water heater is influenced; through the cleaning mechanism, dust on the heat collection pipes can be removed through cleaning, and the situation is avoided that since the dust covers the heat collection pipes, the heat collection effect of the heat collection pipes isinfluenced.
