This application discloses a fireproof sealing device for vertical pipes in high-rise buildings, relating to the field of building fire protection sealing technology. It includes a shell and a fixing plate, with the fixing plate fixed to the side wall of the shell. It also includes a screw, fire-arresting blocks, a fixing ring, a push plate, and a placement cavity. The placement cavity is formed inside the shell, with the push plate slidably connected within it. The screw passes through the side wall of the shell and is threaded onto the shell. The fixing ring is fixed within the placement cavity and located inside the push plate. The fixing ring is circular, and multiple fire-arresting blocks are fixed on it. Each fire-arresting block consists of a fixed block and a movable block. Two fixed blocks are provided, fixed to the inner wall of the fixing ring. The fixed blocks are arc-shaped, and the movable blocks are the same arc-shaped blocks, slidably connected to the inner wall of the fixing ring. Multiple movable blocks and fixed blocks are sequentially assembled to form a complete ring structure. This design, with an adjustable inner diameter, can adapt to various pipes with different outer diameters, reducing procurement costs.

The present application relates to a kind of micro-nano bubble generation processes, belong to bubble generation field, including the following steps: S1, make water flow have preset speed into beam cavity, and in beam cavity, flow in jet form, the beam that flows out from beam cavity and after mixing from air inlet cavity into gas, into flow guide cavity;S2, gas-liquid mixture from flow guide cavity into collision cavity, and in collision cavity, bubble micronization;S3, after impact and the gas-liquid mixture of forming turbulent flow, into rotating cavity, by rotating piece in rotating cavity, impact again, finally with high-speed rotating state shoots out rotating cavity, and high-speed rotating water flow and negative pressure cavity can continuously cut gas bubble, to further produce micro-nano bubble.The present application has the advantages that: water flow and gas are rotated and sheared in turn through beam cavity, flow guide cavity, collision cavity and rotating cavity, and the phenomenon of rotating and shearing breakage or mutual impact occurs, to realize the breakage of gas bubble several times.

The invention discloses a closed-loop positioning collaborative scheduling double-galvanized-wire self-adaptive unbundling robot system which comprises an overline movable single-sliding-table truss module which stretches across a first galvanized-wire steel coil trolley channel and is parallel to a second galvanized-wire unbundling stepping beam. A long-acting operation and maintenance integrated structure and a closed-loop positioning switching module are arranged on the side wall of the second galvanized wire unbundling stepping beam, and the closed-loop positioning switching module and the long-acting operation and maintenance integrated structure achieve precise positioning of the robot between two production lines. The industrial six-axis robot is inversely installed and connected with the tail end in a floating mode, adaptation to steel coils of different specifications is achieved, a single robot conducts double-line-crossing operation, the vacancy rate of equipment is decreased, the utilization rate is increased, and the purchase cost is saved by half compared with double-robot configuration. And the closed-loop positioning switching module ensures that the unbundling device is accurately aligned with the steel coil, so that the unbundling success rate is stable.

According to the anesthesia depth evaluation method based on the electroencephalogram quantitative indexes, the anesthesia depth can be comprehensively and accurately evaluated by combining coupling of frequency domain analysis and information dynamics analysis; by combining electroencephalogram low-frequency energy ratio and electroencephalogram complexity analysis, nonlinear dynamic characteristics and frequency domain energy changes in electroencephalogram signals can be comprehensively captured, multi-dimensional anesthesia depth evaluation is provided, errors and lagging existing in the prior art are effectively avoided, and accuracy and stability of anesthesia depth evaluation are ensured; according to the method, the change of frequency band energy in the anesthesia process can be more rapidly captured, especially the rapid change of delta waves, electroencephalogram complexity analysis has high sensitivity to the complexity change of signals, and the response capacity of the system to the rapid change of anesthesia depth is remarkably improved by combining frequency domain analysis.
