The invention discloses a nonmetal composite hydrogen conveying hose with a multi-form hydrogen blocking layer, and belongs to the technical field of hydrogen conveying hoses, the nonmetal composite hydrogen conveying hose comprises an external pipe, the bottom end of the external pipe is connected with a butt-joint pipe, the bottom end of the butt-joint pipe is connected with a composite hose, the bottom end of the butt-joint pipe is connected with a first sleeve in a penetrating mode, and the top end of the butt-joint pipe is connected with a second sleeve in a penetrating mode; the first sleeve is sleeved on the outer wall of the composite hose, the second sleeve is sleeved on the outer wall of the external pipe, a cavity is arranged in the butt-joint pipe, and a sealing measuring assembly is slidably connected in the cavity of the butt-joint pipe. A complete hydrogen conveying structure is integrally formed by a composite hose, a butt joint pipe and an external pipe, the butt joint pipe is fixedly connected with the composite hose and the external pipe in a sleeving mode through a first sleeve and a second sleeve, an inner cavity provides an installation and sliding space for a test sealing assembly, and the composite hose is of a multi-layer composite structure of a hydrogen conveying pipe, a first hydrogen blocking layer and a second hydrogen blocking layer. And a multi-form hydrogen blocking system with double hydrogen blocking layers and a hydrogen transporting base layer is formed.

The application discloses a live working under parallel groove clamp electric installation device and a wire connecting method, which comprises a clamp body and an insulating rod, the top of the insulating rod is detachably connected with a clamping mechanism, an assembly groove for placing the clamp body is formed in one side of the clamping mechanism, a wire pre-clamping mechanism is connected to the other side of the clamping mechanism, and a clamp locking mechanism is connected to the bottom of the assembly groove. The clamping mechanism, the wire pre-clamping mechanism and the clamp locking mechanism are arranged, electric driving and mechanical design are adopted, the wire is quickly and accurately connected, the efficiency and safety of wire connection in live working are improved, the labor intensity of operators is reduced, and a powerful guarantee is provided for stable operation of a power system.
