AI Technical Summary

Technical Problem

Existing cryogenic gas in-hole energy storage rock fracturing expansion devices lack specialized transport trolleys and fixing clamps, which increases the risk of liquid oxygen leakage and container damage during transportation. Furthermore, the disassembly process is cumbersome and cannot meet the need for rapid replacement.

Method used

A device comprising a mobile cart, a fixed frame, and mobile wheels was designed. The device achieves precise positioning and stable fixation of the liquid oxygen Dewar canister through a snap-fit component, enables quick unlocking and replacement by combining it with an unlocking component, and facilitates convenient transportation and rapid replacement by utilizing the cooperation of a mobile sleeve and a spring.

Benefits of technology

It improves the transportation efficiency and safety of liquid oxygen Dewar canisters, ensures fast and accurate fixing and unlocking operations, reduces safety hazards, and meets the needs of rapid replacement in field operations.
