A memory alloy driving device using gas to isolate cold and hot working fluids

Abstract

The invention discloses a memory alloy driving device that uses gas to isolate hot and cold working fluids, including a motion structure, a driving structure and a hot and cold water gas circulation control structure; the motion structure is mainly composed of blades, connecting rods, pins, and bracket stabilizers. . The driving mechanism of each blade mainly consists of a memory alloy spring, a cylinder, two fixed discs, a compression spring, and a push rod. The three holes of the disc are threadedly connected to the ends of the three cylinders respectively, and the three pairs of square holes of the disc are connected to the three bracket stabilizers using an interference fit. The hot and cold water gas circulation control structure mainly consists of a cold water pump, a hot water pump, a cavity, an electronic control component box, an air pump, a two-position three-way electromagnetic reversing valve, a gas storage tank, an exhaust valve, a process hose, a return hose, Composed of various connectors, etc. This device has the characteristics of low noise, little impact on the environment, low energy consumption, high theoretical thermal efficiency, and relatively low cost. It is mainly used in the field of water surface transportation vehicles.

Description

technical field [0001] The invention relates to the technical field of water surface and underwater vehicle drives, in particular to a memory alloy drive device using gas to isolate cold and hot working fluids. Background technique [0002] Today's nuclear submarines generally use the materials in the nuclear reactor to undergo nuclear fission under artificial control to generate high temperature, and use the obtained high temperature to heat the high-pressure water in the primary circuit. After passing through the steam generator, the high-heat and high-pressure water transfers heat to the secondary circuit. The circuit makes the water in the secondary circuit be heated into steam, and then use the steam to drive the steam engine. The steam engine can directly drive the propeller, or it can be connected to a generator to generate electricity, so as to achieve the purpose of nuclear submarine navigation. But on the one hand, the process of these energy conversions has caused...

Problems solved by technology

But on the one hand, the process of these energy conversions has caused a lot of energy loss; on the other hand, the process of nuclear fission of nuclear materials is extremely dangerous. In addition to strong radiation, nuclear leakage may also occur, resulting in irreversible nuclear pollution.
