As shown in Figure 1, the solar panels 205 of tradition solar tracking system are placed on the support bar 109, support bar 109 is fixed in base 100, its light sensing cell is placed in four orientation, center of solar panels 205 by four light sensing components 101,102,103 and 104, and sleeve 120 cover caps are at sensing component 101,102,103 and 104 peripheries.Photovoltaic element 108 is placed in the surface perimeter of solar panels 205, accepts solar energy, then solar energy is converted into electric energy.When the sun by directly over direct projection during, four light sensing components 101,102,103 and 104 light income homogeneous to this traditional solar tracking system.In order to make photovoltaic element 108 can receive stronger irradiation of sunlight always, photovoltaic element 108 must be always facing to the position at sun place, therefore the orientation of controlling solar panels 205 makes the orientation of its sun-tracing and can automatic always correction position face toward the sun, make photoelectric subassembly 108 can receive the sunlight of direct projection, be very important for solar photovoltaic system always.
As shown in Figure 1, the operation principle of the solar tracking system that this is traditional is: directly over sun skew is left during the position, the limit wall shadow of sleeve 120 can cover contiguous light sensing component gradually, cause four light sensing components to detect the varying strength of light respectively, these signals are sent to after the control unit, just can drive solar tracking system and adjust direction and make photovoltaic element can receive the sunlight of direct projection once again.As shown in Figure 1, when the sun when move on the left side, the following light of light R1 is covered by sleeve 120, can't enter sleeve inner, in other words, be exactly that light sensing component 101 is covered by the shade that the limit wall of sleeve 120 is produced gradually, a little less than light sensing component 101 received light intensities with respect to light sensing component 103 are, these signals are passed to after the control unit, just can drive stepper motor, solar tracking system is turned to certain direction, thereby can reach the solar tracking effect, and make photovoltaic element 108 can maintain stronger irradiate light relatively always.
Be the fundamental diagram of above-mentioned traditional solar tracking system arrangement for deflecting as shown in Figure 2, control unit 12 is coupled in gear train 107 and power supply 13, and gear train 107 is coupled in solar panels 205.Control unit 12 makes power supply 13 drive gear set 107 according to the control power supply 13 that imposes a condition, and makes the certain angle of solar panels 205 deflections.
The shortcoming of above-mentioned traditional solar tracking system is that its gear unit 14 includes gear train 107, driving by power supply 13, adjust the deflection of solar panels 205, this gear train 107 deflection systems need more power consumption, for 205 electric energy that can produce of solar panels, form very big energy efficiency problem.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of bulbs of pressure of using the refrigerant accumulator to be heated and to be produced to promote the deflection solar panels, to save the solar tracking system that promotes the required electric energy of solar panels.
