Description

Reflection tracing solar energy water heater

The utility model has related to the use device of solar energy, is particularly for a kind of skin tracking formula solar water heater, is applicable to that hotel, restaurant and residential building use.

Along with science and technology development, solar energy is widely used in national economy, and is outstanding and be various forms of solar water heaters, constantly promoted and use, and made things convenient for people's lives, saved the energy.Existing water heater mostly is tube-sheet type greatly, and the thermal efficiency is low, and solar energy utilizes insufficient, and consumptive material is many.A kind of solar tracking water heater is arranged, and is to utilize a condenser to the heating of the water heater on its focus, and utilizes a simple electronic circuit control condenser to follow the sun and rotate, and has prolonged heat time heating time, has improved the thermal efficiency.But this solar water heater is a unenclosed construction, and heating tube and thermal-arrest plate are directly sudden and violent to be leaked outside, has influenced the thermal efficiency and the service life of water heater.

It is long that the purpose of this utility model is to disclose a kind of thermal efficiency height, service time, can make full use of the safe and reliable solar water heater skin tracking formula solar water heater that not influenced by external condition of solar energy, so that solar water heater obtains better application.

Design of the present utility model is to manage the solar energy focus utilization is gathered sunshine to greatest extent, increases operation rate and is not subjected to the influence of atmosphere outside.

Task of the present utility model is to finish by the cooperating of a reflective focused type heat-collecting box and a cover drive unit.

Concrete heat-collecting box is made up of shell, thermal-collecting tube and glass plate.Shell is a parabolic housing, is coated with one deck reflectorized material on parabolic (daylighting face), and a upper cover plate and a lower cover are housed on shell, and a glass plate is equipped with in the front of shell, constitutes a heat collecting tank that seals with shell.Thermal-collecting tube is a metal tube of vertically laying, and is positioned on the focus of parabolic shell, and the two ends of thermal-collecting tube are connected mutually with the circulating water pipe of water tank, and is connected and fixed on externally the fixing support by being contained in two connecting plates up and down on the pipe.The towing plate of half garden shape also is housed in the upper end of thermal-collecting tube, and towing plate is to be fixed on the heat-collecting box upper cover plate, and is connected with a drive unit by dress chain rope thereon.Drive unit includes a light-operated switch and a transmission mechanism.Transmission mechanism is by motor, and worm gear, worm screw, leading screw, sprocket wheel and chain rope are formed, and the chain rope has two, and the one end is connected to the two ends of leading screw, and the other end passes through the reverse solderless wrapped connection of sprocket wheel on the towing plate of heat-collecting box.Light-operated switch is a phototriode, is contained on the right edge of heat-collecting box shell, is connected in the power circuit of motor by a simple electronic amplification circuit, and the control motor is done and is rotated in the forward.Drive unit of the present utility model is that arrangement is set like this, when the sunlight front illuminated is on the daylighting face of heat-collecting box, is positioned at light-operated switch on the heat-collecting box right edge and adopts less than sunlight and be in open position.The drive unit dead electricity is not worked, and at this moment the parabolic shape daylighting face in the heat-collecting box can be concentrated sunlight to greatest extent and reflex on the thermal-collecting tube, has made full use of solar energy.When sunshine moves 1 degree (about 4 minutes) westwards, the light-operated switch that is positioned on the heat-collecting box right edge just collects sunshine and closure, connected the power circuit of drive unit, drive unit work, the chain rope drives heat-collecting box dextrad by towing plate and rotates, when turning to 1 when spending, light-operated switch can disconnect because of avoiding sunlight once more, the drive unit power down is not worked, like this, and along with sunshine rotation from east to west, the heat-collecting box of water heater under the mirror control of light-operated switch slowly tracks sunlight rotate synchronously, guaranteed that in the process that sunshine moves heat-collecting box can reflex to sunshine on the thermal-collecting tube to greatest extent, the high efficiency solar energy that utilized.Also be connected to a limit switch in the circuit of this practical motor at drive unit, (among the figure draw in the end), in heat-collecting box rotates during certain position (before roughly the sun sets), limit switch is affected closure, oppositely connected motor, drive unit oppositely leads the cover drive unit and can drive a plurality of heat-collecting boxes and follow the sun and synchronously rotate, and simplified structure has enlarged the scope of application.

Novel great advantage is at an airtight heat-collecting box, the thermal-arrest plate of parabolic shape can be concentrated sunlight and reflex on the thermal-arrest water pipe that is positioned at the focus place, and heat-collecting box can be followed the tracks of moving of sunray and synchronously rotate, thereby guaranteed to make full use of solar energy, improved the thermal efficiency of water heater.
