Abstract

The invention provides a two-way water-jet propeller based on shape memory alloys and a control method of the two-way water-jet propeller. The two-way water-jet propeller based on shape memory alloys comprises a memory alloy driving module, a two-way water-jet propulsion module, a water flow one-way distribution module and a controller, wherein the memory alloy driving module comprises a cylinder body, a piston and two shape memory alloy springs; the two-way water-jet propulsion module comprises two water-jet pipes; the water flow one-way distribution module comprises a first valve group and a second valve group; the first valve group comprises a one-way valve 1, a one-way valve 2, a two-position three-way valve 1 and a two-position three-way valve 2; the second valve group comprises a one-way valve 3, a one-way valve 4, a two-position three-way valve 3 and a two-position three-way valve 4; and the shape memory alloy springs, two-position three-way valve 1, two-position three-way valve 2, two-position three-way valve 3 and two-position three-way valve 4 are respectively connected with the controller. The noise of the two-way water-jet propeller based on the shape memory alloys is decreased, and the working efficiency is improved.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a bidirectional water jet propeller based on a shape memory alloy and a control method thereof. Background technique [0002] The current propulsion method for surface and underwater transportation is mainly the propeller propeller. The propeller propulsion method will cause cavitation during operation, which will generate huge noise and seriously affect the concealment of underwater operation. For this reason, people have invented water-jet propulsion device, and common water-jet propulsion device is to generate thrust by propulsion pump, utilizes the reaction force of the water jet of pump to propel aircraft forward. However, in actual use, the noise generated by the operation of the water pump is relatively large. How to design a water jet propeller with low noise and high working efficiency is the technical problem to be solved by the present invention. Contents of the invention ...
