Low-power water terminal shell

Abstract

This invention relates to a low-power water terminal housing, comprising a base plate and a housing. The housing is mounted on the base plate and contains multiple airbags. Each airbag includes an airbag cavity and a shape memory alloy frame. The shape memory alloy frame is disposed on the inner wall of the housing, and the airbag cavity is disposed on the outer surface of the shape memory alloy frame. The shape memory alloy frame is similar in shape to the airbag. The outer surface of the airbag cavity is coated with a microcapsule coating. An air tube is disposed on the air inlet of the airbag cavity, and an air valve is disposed on the air tube. In this invention, when the water terminal is placed in a deep body of water for water quality collection, the water pressure outside the housing gradually increases. The external water pressure is transmitted to the airbags through the housing, causing the airbags to be compressed. The volume of gas inside the airbags decreases, and the pressure increases. At this time, the airbags expand inward toward the housing, generating reverse pressure on the inner wall of the housing to counteract the external water pressure, thereby balancing the pressure inside and outside the housing and preventing deformation and damage to the housing.
