AI Technical Summary

Technical Problem

Existing ecological enclosures in cold northern waters suffer from long periods of ice cover and low water temperatures, leading to the tearing and damage of soft enclosures due to the frost heave of ice. Furthermore, they lack the capacity to actively improve water quality and are not self-sufficient in energy, making it difficult to support the growth of submerged plants and meet their light requirements.

Method used

The enclosure is made of rigid mesh material, combined with mechanical lifting cylindrical columns, floating components and counterweights. It uses the frost heave force of ice to drive the lifting columns to rise. It is equipped with a solar power supply system and a spectrum supplementary lighting system, combined with a heat-absorbing and anti-icing coating to achieve adaptive lifting and energy self-sufficiency.

Benefits of technology

It effectively prevents the enclosure from tearing due to freezing and heave of ice, improves the overwintering survival rate of submerged plants, enhances water purification efficiency, adapts to remote waters without external power supply, reduces maintenance costs, is highly adaptable, and is easy to install.

Abstract

The application discloses a kind of northern cold water body anti-ice expansion self-lifting ecological enclosure systems, belong to aquatic ecological restoration technical field, the system includes: enclosure main body;Mechanical lifting cylinder type column, including fixed bottom column and sliding sleeve in its inside lifting column, fixed bottom column lower end is anchored to water bottom, lifting column upper end is fixedly connected with enclosure main body;Floating body assembly, fixedly connected to the top of lifting column;And counterweight, set in the lower part of lifting column, ice cover is frozen as a whole with floating body assembly when icing, the upward jacking force generated by ice layer frost heaving drives lifting column to slide upwards along fixed bottom column, so that enclosure main body is lifted as a whole to above ice layer frost heaving influence area;After ice layer melts, enclosure main body is automatically dropped to the design water level position under the joint action of dead weight and counterweight gravity, and the lifting mechanism is pure physical passive self-adapting structure, without any electrical or mechanical drive, fundamentally solve the technical problem that traditional enclosure is torn and damaged due to ice layer frost heaving in northern cold water body.
