But the solar water heater under prior art does not solve the problems of the technologies described above, it can only be contained on roof or balcony regularly.The track of the sun can not be followed the tracks of, just can not absorb solar energy to greatest extent.At weather not good enough or in the winter time time can therefore cause heat production not enough.On the other hand, because it is fixedly mounted in roof or balcony, so it can not meet by changing the absorption protection solar water heater that external corner reduces heat when water temperature over-high.
Summary of the invention
Automatically can regulate according to time and water temperature to make solar water heater and meet external corner (the angle degree of the maximum heat-absorbent surface of solar water heater and sunray); solar energy and protection solar water heater can be absorbed to large extent; this invention takes following technical measures: solar water heater is movably arranged on ground or balcony; the thermometer of solar water heater water tank connects computer; computer connects electric machine controller; electric machine controller connects motor, and motor rotates by actuator drives solar water heater.Solar water heater can under control of the computer water tank water temperature lower than during setting value keep maximum heat-absorbent surface towards the sun, when water tank water temperature higher than during setting value keep minimum heat-absorbent surface towards the sun.
The benefit done like this is: solar water heater can rotate under the driving of the control of computer and motor, obtains maximum heat energy and protection solar water heater creates necessary condition for solar water heater.When concrete benefit is solar water heater work, computer is according to time (clock in computer), and command motor drives solar water heater to rotate, and the maximum heat-absorbent surface holding surface of solar water heater can be made to the sun, namely follow the tracks of the sun, obtain maximum heat energy.Simultaneous computer is connected to the thermometer in water tank; when the water temperature over-high in water tank or when reaching setting value; computer drives solar water heater to rotate by motor; make the minimum heat-absorbent surface holding surface of solar water heater to the sun; reduce heat energy to greatest extent to obtain; prevent water temperature over-high, make solar water heater protected.
