Memory alloy driving device by adoption of gas isolating cold and hot working media

Abstract

The invention discloses a memory alloy driving device by adoption of gas isolating cold and hot working media. The memory driving device by adoption of the gas isolating the cold and hot working media comprises a moving structure, a driving structure and a cold-hot water and gas circulating control structure, wherein the moving structure is composed of blades, connecting rods, hinge pins and supporting frame firming pieces. The driving structure of each blade is composed of memory alloy springs, air cylinders, two fixing round plates, pressure springs and push rods. Three holes of the front section fixing round plate are connected with ends of the three air cylinders in a threaded mode, and three square holes of the rear section fixing round plate are connected with the three supporting frame firming pieces in a interference fitted mode. The cold-hot water and gas circulating control structure is composed of a cold water pump, a hot water pump, a cavity, an electronic control unit box, an air pump, a two-position and three-way electromagnetic directional valve, a vent valve, an enter stroke hose, a return stroke hose, various connecting pieces and the like. The memory alloy driving device by adoption of the gas isolating the cold and hot working media has the characteristics of being low in noise, less in environmental influence, low in energy consumption, high in theoretical thermal efficiency and low in cost, and is mainly applied to the field of water transportation tools.

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.
