When strong, after the water temperature in water storage tank reaches sets requirement, water supply tank can be automatically switched to, is mainly used for heat to electricity conversion, it will
Power storage is in battery.
After sunlight is focused on vacuum tube by reflecting piece, although spiral heat absorption pipe is in vacuum tube, sunlight is irradiated to vacuum
Guan Hou is transferred heat on spiral heat absorption pipe and is still needed medium, and medium can consume a certain amount of during transmitting heat
Heat, so the temperature of spiral heat absorption pipe and the temperature of vacuum tube are different, the heat that the water in spiral heat absorption pipe receives
It is also different for measuring from the temperature of vacuum tube, in order to guarantee the accuracy of water heating, so need to check vacuum tube Current Temperatures, with
It is matching conducive to subsequent step.
In step s 102, according to the pass between the Current Temperatures of the vacuum tube and the temperature of spiral heat absorption Guan Zhongshui
System, determines the target temperature of vacuum tube.
The Current Temperatures of vacuum tube are higher, and the temperature of spiral heat absorption Guan Zhongshui also can be higher, in order to accurately determine spiral
The temperature of water in absorbing pipe, so the heating of the water in spiral heat absorption pipe is from vacuum it needs to be determined that the target temperature of vacuum tube
Heat is absorbed in pipe, for example, heating the water to 60 degree, determination needs for the temperature of vacuum tube to be adjusted to 180 degree, spiral heat absorption pipe
Water is heated after absorbing the temperature of vacuum tube.
If it is desired to accurately heating the water to specified temperature, need that vacuum tube is accurately heated to specified temperature,
The position of the sun is in variation, if not changing the position of reflecting piece, sunlight is irradiated to the focus level on vacuum tube and also can
Weaken, in order to preferably control the temperature of vacuum tube, the position and reflecting piece product, stepper motor for needing to adjust reflecting piece drive anti-
Mating plate rotation, postrotational reflecting piece refocus sunlight on vacuum tube, the sunlight that the temperature of vacuum tube is completely refocused
It heats again, temperature sensor detects the temperature of vacuum tube, after the temperature of vacuum tube reaches estimated temperature, passes through control

In step s 103, according to the target temperature of the vacuum tube, the initial target location of reflecting piece is determined.
After the temperature of the target of vacuum tube determines, need that reflecting piece is adjusted to suitable position according to previous experience,
Temperature sensor detects the temperature of vacuum tube at this time, if the temperature of vacuum tube does not reach temperature estimated in advance, determining is needed
The position for readjusting reflecting piece, focuses on sunlight preferably on vacuum tube, and the temperature of controller on the estimation calculates
Lighting angle uses and determines initial target location according to lighting angle.
In step S104, the position of reflecting piece is adjusted to initial target location.
After reflecting piece initial target location determines, controller starts the position of stepper motor and electric putter adjustment reflecting piece,
The position of reflecting piece is set to reach initial target location, controller records the collapsing length of stepper motor turned position and electric putter,
After the temperature of vacuum tube reduces, controller will start the position of stepper motor and electric putter adjustment reflecting piece, to make sunlight
It refocuses on vacuum tube, the position of reflecting piece adjusts based on initial target location, if reflecting piece is in the mistake of adjustment
No adjustment basis in journey, the efficiency of adjustment can be very low, it may appear that adjusts repeatedly but vacuum tube arrival can not always expected
Temperature phenomenon uses using based on initial target location as object of reference in order to avoid this phenomenon, improves the tune of adjustment reflecting piece
Whole efficiency.
In step s105, it analyzes in the spiral heat absorption pipe, the temperature and semiconductor temperature differential power generating sheet output voltage of water

Degree after vacuum tube reaches suitable temperature, makes spiral heat absorption pipe reach estimated temperature, so that the temperature of water be made to reach estimated
The temperature difference of temperature, hot water and cold water reaches estimated standard, it is ensured that the stability of output voltage.
Referring to Fig. 2, in one possible exemplary embodiment of the disclosure, use can according to according to vacuum tube and
Temperature relation between spiral heat absorption pipe determines the target temperature of vacuum tube.
In step s 201, the temperature of spiral heat absorption Guan Zhongshui is detected,
Heat is transmitted between vacuum pipe outer wall and spiral heat absorption pipe and needs medium, and medium is during transmitting heat
A part of heat can be consumed, in order to rationally accurately control the heating temperature of water, so need to detect the temperature of spiral heat absorption pipe,
To reasonably control the temperature of water.
In step S202, judge the temperature of spiral heat absorption Guan Zhongshui whether within the scope of default temperature.
The temperature of water is judged whether between 30~90 DEG C, and the temperature difference of hot water and cold water generates electricity output voltage at 60 degree
Effect is best.
In step S203, judge that the temperature of spiral heat absorption Guan Zhongshui whether within the scope of default temperature, determines vacuum
The target temperature of pipe.

The temperature difference of water and cold water generate electricity at 60 degree output voltage effect it is best, water temperature reaches 90 DEG C, and the temperature needs of vacuum tube reach
To 200 DEG C.
In step S204, if the temperature of spiral heat absorption Guan Zhongshui not within the scope of default temperature, again to spiral
Water in absorbing pipe is heated.
Preset temperature range is between 30~90 DEG C, if the temperature of spiral heat absorption Guan Zhongshui is not in preset temperature model
In enclosing between 30~90 DEG C, the water in spiral heat absorption pipe is heated again.
Against the sun, sunlight is radiated in the reflecting piece of square face arc reflecting piece, and sunlight is reflected, focused on by reflecting piece
On vacuum tube, heat is transmitted to the water in spiral heat absorption pipe by the spiral heat absorption pipe in vacuum tube, and water is transported to the temperature difference by water pump
Enter water storage tank after the hot end water-cooling head of generating set, the cold water in water storage tank flows through semiconductor temperature difference under the action of water pump
It heats, so constantly recycles, in the cold of thermo-electric generation unit in the spiral heat absorption pipe entered in vacuum tube after the cold end of power generation sheet
Hot both ends form the temperature difference, are allowed to generate electricity, and electric energy is stored into battery by charging circuit, semiconductor temperature differential power generating sheet hair
While electric, water is stored in water storage tank by circulating-heating.When temperature sensor detects the (temperature when the temperature is excessively high in vacuum tube
Degree is no more than 200C DEG C), temperature controller just will start stepper motor, shrinks reflecting surface and reduces area, light energy is reduced, temperature
Degree decline, guarantees that vacuum tube is unlikely to burn out；When temperature sensor detect thermoelectric generation film temperature it is too low when, temperature control
Device will start stepper motor and electric putter again, and spread reflection face increases area, and light energy increases, and temperature increases, and guarantee semiconductor
Thermoelectric generation film works under the big temperature difference, improves conversion efficiency of thermoelectric.When sun in summer light is excessively fierce, in water storage tank
Water temperature reach sets requirement after, water supply tank can be automatically switched to, be mainly used for heat to electricity conversion, by power storage in battery
In, rated limits are carried out for temperature of the highest stabilizing to vacuum tube with 200 degree, water temperature is maintained at optimum temperature always, also will

Predetermined temperature is 200 DEG C, carries out real-time monitoring, the temperature of vacuum tube by temperature of the temperature sensor to vacuum tube
When being 200 DEG C, the heating temperature of water can reach most preferably, while spiral heat absorption pipe will not be damaged because temperature is excessively high, thus
Need to judge the temperature of vacuum tube whether at 200 DEG C.
In step S303, if the real time temperature of vacuum tube reaches predetermined temperature, determine that the location of reflecting piece is
Initial target location.
