Abstract: Disclosed is a carbon-dioxide-responsive self-thickening intelligent fluid based on supramolecular self-assembly, which comprises a Gemini surfactant, a single-chain amide molecule having a tertiary amine head group and water, wherein the Gemini surfactant and the single-chain amide molecule are self-assembled to form a vesicle structure dispersed in water, with a hydrophilic head group being located outside and a hydrophobic tail group located inside. The method for preparing the carbon-dioxide-responsive self-thickening intelligent fluid of the present invention is simple, the injection viscosity is low, and the fluid is converted into a gel when encountering carbon dioxide, so that the viscosity is greatly increased.

Abstract: A system synchronization method includes: connecting synchronization modules of a plurality of devices together through a synchronization bus. The synchronization modules include a signal generation module, a switch control module, a synchronization bus monitoring module, and a switch S1. A signal output terminal of the signal generation module is connected to a first terminal of the switch S1, and a timing overflow terminal of the signal generation module is connected to the switch control module configured to control the switch S1. The switch control module is connected to the synchronization bus monitoring module. A second terminal of the switch S1 is connected to the switch control module and the synchronization bus monitoring module. The system synchronization method has the advantages of simple structure, low cost, high reliability, and good practicability.

Abstract: Disclosed is an adjustable roller carrier, comprising a roller carrier base (1), rollers (2) and a motor speed reducing driver, wherein both ends of the roller carrier base are each articulated with a roller bearing (3) and a roller carrier hydraulic jack (5), with the roller carrier hydraulic jack (5) being articulated with the roller bearing (3) and the roller (2) being mounted on the roller bearing. The roller carrier hydraulic jack and a hydraulic pump station thereof, and an electromagnetic valve are all placed inside a hollow roller carrier support so that not only the height and the center-to-center distance of the rollers are adjustable, but also the adjustable roller carrier has the advantages of being integrally compact in structure, and small in terms of occupied space. The adjustable roller carrier enables the steel pipe to rotate in a narrow space, can be fast lifted, and transported by railway. The adjustable roller carrier is convenient to operate and has high safety.
