Abstract
The utility model relates to a solar water heater comprising a transparent shell and a transparent tank (water storage), the bottom of the tank is provided with a layer of black material which plays a role in heat collecting; the top of the shell has a convex lens, and the convex lens focuses on the black material at the bottom of the tank; the shell and the tank can be made of glass; the black material can be a dope or a ceramics. In order to utilize the function of convex lens in maximum, the utility model is provided with a solar tracker device, and the solar tracker device comprises a photodetector and an actuating unit; the convex lens is faced to the sun all the time. The utility model has the advantages of higher utilization rate and thermal efficiency.
Description
Technical field the utility model relates to a kind of solar water heater.
Background technology is present, and known solar water heater is made up of water tank and thermal-collecting tube, and water tank is loaded on the top of thermal-collecting tube, and whole solar water heater is fixed, and solar energy utilization ratio is lower, and this is its shortcoming.
The summary of the invention the purpose of this utility model is to provide a kind of solar energy utilization ratio higher solar energy water heater.
The utility model is made up of a transparent outer cover and a transparent inner bag (water receiver), the inner bag bottom has one deck to play the black material of thermal-arrest effect, shell upper has convex lens, convex lens focus is on the black material of inner bag bottom, shell and inner bag can adopt glass to make, and described black material can be coating or pottery.In order to bring into play the effect of convex lens to greatest extent, the utility model is provided with sun tracker, and sun tracker is made up of photodetector and actuating unit, makes convex lens always facing to the sun.For the ease of regulating and daylighting, shell of the present utility model and inner bag can be made egg type or sphere.In order to improve the thermal efficiency, the state that can be evacuated of the space between shell and the inner bag.
The beneficial effect of the utility model structure is: the solar energy utilization rate and the thermal efficiency are higher.
Description of drawings further specifies the utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a photodetector schematic diagram of the present utility model.
Fig. 3 is a sun tracker functional-block diagram of the present utility model.
Among the figure: 1. shell, 2. water inlet pipe and water outlet pipe, 3. black material layer, 4. inner bag (water receiver), the 5. convex lens on the shell, 6. photodetector; 61. the photodetector base, 62. shelters, 63A, 63B, 63C, 63D. optoelectronic induction head; R1, R2, R3, R4. resistance, V. power supply, 64. amplifiers, 65. actuating units.
Embodiment is referring to Fig. 1, and the utility model is made up of shell 1, inner bag 4 and black material layer 3, it is characterized in that: shell 1 adopts transparent material to make, and its top is a protruding ytterbium 5; Inner bag 4 adopts transparent material to make, and black material layer 3 is arranged at its bottom.Water inlet pipe and water outlet pipe 2 is arranged on the inner bag 4.A photodetector 6 is arranged in the outside of convex lens 5.In embodiment of the present utility model, inner bag, shell adopt glass to make.Black material layer 3 adopts pottery to make.
Referring to Fig. 2, in embodiment of the present utility model, the optoelectronic induction head of photodetector 6 adopts 4 photo resistance 63A, 63B, 63C, 63D to be loaded on the base 61, the centre has shelter 62 to separate, shelter 62 is higher than photo resistance, 4 photo resistance are all shined upon when sun direct projection, and when sun oblique fire, certain 1 or 2 photo resistance thing 62 that is blocked stops.
63A and 63B, 63C and 63D combo consist of two groups of balanced bridges, are connected with two groups of amplifiers respectively, and two groups of amplifiers are connected with two groups of actuating units respectively, follow the tracks of the sun from east-west direction for one group, and another group is followed the tracks of the sun from North and South direction.The drawn combo electric bridge of 63A and 63B of Fig. 3, this electric bridge is made up of resistance R 1, R2, R3, R4, power supply V and photo resistance 63A, 63B, and the electric bridge output is connected with an amplifier 64, and amplifier 64 is connected with actuating unit 65, form sun tracker, make convex lens over against the sun.Mechanical part in the actuating unit can be screw regulator or fluid pressure governor, adopts water-pressure regulating device in the utility model, and this is well-known to those skilled in the art, no longer describes in detail.When the sun during over against photodetector, photo resistance 63A is identical with the resistance of 63B, the bridge balance no-output; When the sun casted oblique rays on, a certain photo resistance thing 62 that is blocked blocked and is not shined upon, and resistance changes, electric bridge is unbalance, and potential difference output is arranged, and is exaggerated device 64 and amplifies 65 actions of back control actuating unit, regulate the inclination angle of solar water heater, make convex lens always over against the sun.
For the ease of regulating and using, shell of the present utility model and inner bag can be made egg type or sphere.And the state that is evacuated of the space between shell and the inner bag.
