Embodiment
Below in conjunction with accompanying drawing, invention is described in further detail.
Embodiment 1: device of solar generating, comprises multiple thin-film solar cells, 10 N type semiconductors, 10 P type semiconductors, thermal conductive water pipe, secondary battery unit, controller unit, 40 temperature sensors, water pump, 10 electric control valves, 10 water pipes and 1 radiating tube; The length of 10 water pipes is respectively 5 meters, 10 meters, 15 meters, 20 meters, 25 meters, 50 meters, 75 meters, 100 meters, 125 meters, 150 meters, is all arranged at below ground perpendicular to ground.N type semiconductor, P type semiconductor are all in " work " font; The cross section of thermal conductive water pipe is square; N type semiconductor and P type semiconductor are spaced, and connect between adjacent N type semiconductor and P type semiconductor; Multiple thin-film solar cells series connection, then connects with N type semiconductor and P type semiconductor, last accumulators unit charging; Multiple thin-film solar cells is arranged at the upper surface of N type semiconductor, P type semiconductor, and the contact-making surface of thin-film solar cells and N type semiconductor, P type semiconductor insulate; The lower surface insulated contact of the outer surface of described thermal conductive water pipe and N type semiconductor, P type semiconductor; The upper surface of N type semiconductor, P type semiconductor and the equal set temperature transducer of lower surface, temperature sensor is electrically connected with controller unit; Described N number of water pipe all perpendicular to ground, and is arranged at below ground; Described water pipe connects the water inlet of water pump respectively by electric control valve, and the delivery port of water pump connects the water inlet of thermal conductive water pipe; The IO port of the control end equal connection control device unit of electric control valve, such controller unit can control conducting and the closedown of each electrically operated valve, and controller unit controls startup and the stopping of water pump simultaneously.
As shown in Figures 4 and 5, radiating tube bends the bottom be arranged between spaced N type semiconductor and P type semiconductor, directly can be placed on the top of N type semiconductor and P type semiconductor bottom wing plate when mounted, make between adjacent N type semiconductor and P type semiconductor, to be equipped with " U " shape bending segment, and the U-shaped mouth of each " U " shape bending segment is towards identical; The water inlet of radiating tube is connected with the delivery port of water pump.
Wherein, described controller unit adopts AT89S52 single-chip microcomputer.The water inlet of described water pump is the delivery outlet of the electric control valve being connected each water pipe by the conversion equipment of a multiple input single output.
Wherein, temperature sensor is arranged at the upper and lower surface of N type semiconductor, the upper and lower surface of P type semiconductor respectively, the data of the temperature sensor collection that upper surface is all are averaged, the data of the temperature sensor collection that lower surface is all are averaged, so latter two mean value gets difference, and when difference is maximum, thermo-electric generation is most effective.
Operation principle of the present invention illustrates: the length of multiple water pipe is not identical and be vertically installed in subsurface and be all connected with water pump, because underground water is constant temperature, and degree of depth different temperatures is different, such as when summer, outdoor temperature is high, and the temperature of underground water is low, solar light irradiation thin-film solar cells generating when daytime in summer, certain heat can be produced while generating, this part heat is delivered to N type semiconductor, the upper surface of P type semiconductor, as hot junction, and the temperature of underground water is lower, N type semiconductor is passed to by thermal conductive water pipe, the lower surface of P type semiconductor, also be delivered to N type semiconductor by radiating tube simultaneously, bottom (on downside) between P type semiconductor, as cold junction, thus be beneficial to cold and hot end thermo-electric generation, otherwise when winter, when winter, outdoor temperature is low and the temperature of underground water is high.
When change in depth is larger, namely from macroscopic view, more deep water temperature is higher for underground water.From ground down often dark 100 meters, temperature approximately increases 2-3 degrees centigrade.The formation temperature of 5 ~ 10 meters below earth's surface does not just change with the change of outside atmosphere temperature, maintains 15 ~ 17 DEG C throughout the year.
As for why have employed 4M temperature sensor? reason is as follows: the numerical value of the temperature sensor collection of the upper surface of N type semiconductor, P type semiconductor is averaged to average with the numerical value of the temperature sensor collection of the lower surface of N type semiconductor, P type semiconductor and done difference, and difference larger thermo-electric generation efficiency is higher; It is more accurate that exact value of averaging difference judges.
As for why have employed multiple water pipe? reason is as follows: when summer, and underground water temperature is lower, but the underground water temperature near earth's surface is also higher, and when the degree of depth acquires a certain degree, water temperature can be more and more higher; When winter, underground water temperature can be higher, but the underground water temperature near earth's surface also can be lower, and when the degree of depth acquires a certain degree, water temperature can be more and more higher; Such water pump, by connecting multiple water pipe, needs can select that water pipe (namely the upper and lower surface temperature approach of N type semiconductor, P type semiconductor is maximum) being conducive to thermo-electric generation most when generating.
Controller unit controls starting mode of pump, then the water in different water pipe is extracted in circulation, this time N type semiconductor, the temperature of temperature sensor collection that arranges of the upper surface of P type semiconductor and lower surface does difference, when if water pump connects 20 meters of dark water pipes, temperature approach is maximum, and so the water pump water pipe that just employing 20 meters is dark always supplies water, and the generating efficiency of such thermo-electric generation is maximum, and the delivery port of thermal conductive water pipe can connect water supply installation, such as water tank etc.
