Embodiment
Embodiment one
With work the petering out of earth energy, be the basis with solar energy utilization, material engineering and bionics techniques progress, arise at the historic moment in conjunction with the present embodiment of ancient clockwork spring principle.The solar energy storage apparatus of present embodiment is mounted with sunlight aggregation apparatus, energy conversion device and mechanical energy accumulator device on the frame 1 shown in Fig. 1 to 4.The sunlight aggregation apparatus is can be with the focus lamp 2 of solar light focusing on marmem 3.Energy conversion device is for converting memory alloy 3 deformation to the driving mechanism of one-way rotation; This driving mechanism by the middle part hinged on frame 1 lever 4, with frame 1 constitute sliding pair tooth bar 5, with the accumulation of energy gear 6 of tooth bar 5 engagement; And constitute with the ratchet 7 of accumulation of energy gear 6 through ratchet 8 coaxial engagements in unidirectional, a side of ratchet 7 is equipped with stopping ratchet 14.The mechanical energy accumulator device is an end and frame 1 relative fixed, the other end and ratchet shaft 9 relatively-stationary accumulation of energy wind springs 10.One end of marmem 3 is fixed near the focal position of focus lamp 2, and an end of the other end and lever 4 is hinged.The other end of lever 4 has the chute that forms sliding pair with tooth bar 5 upper pins 11.
In addition, hinged on the frame 1 have a light barrier 12 that is positioned on the focus lamp 2 tunnel, and the hinging supporting shaft of this light barrier meshes with tooth bar 5 through driven gear 13 and connects.
When sunlight was focused on the memory alloy, the deformation that memory alloy produces was ordered about the tooth bar translation through lever, drove the accumulation of energy gear and turned an angle, and then through ratchet mechanism rolling-in accumulation of energy wind spring, realize that changing solar energy into mechanical energy accumulates.When memory alloy tightened the accumulation of energy wind spring through driving mechanism, light barrier forwarded the position that covers condenser to, thereby memory alloy no longer is heated; When memory alloy turns cold recovery; Lever and tooth bar, accumulation of energy gear all reset (under the unilateral constrain effect of interior ratchet; Ratchet does not turn round); Light barrier then returns to the position of opening condenser once more under the drive of driven gear; Make solar light focusing once more on marmem, circulation does not automatically stop circular energy storage thus; Solar energy is constantly accumulated in the accumulation of energy wind spring in a steady stream, until it is rolled up to the tightest state.
The memory alloy of present embodiment adopts nickel-titanium alloy material to make, and its bending deformation quantity is big, and plasticity is high, and fatigue life is long, stretches bent number of times and can reach 10
