Abstract: Provided is an insulating coating device for an electric wire, including a pressing pipe. The pressing pipe includes two first pressing parts which are configured to divide the pressing pipe into two parts along a longitudinal cross section of the pressing pipe, an inner wall of the pressing pipe is provided with an air bag, and the air bag is provided with an air pipe joint which penetrates to an outside of the pressing pipe. In the insulating coating device for the electric wire, a self-curing insulating material is coated on joints of the electric wires, the air bag is used to squeeze the self-curing insulating material such that the self-curing insulating material is shaped and compacted, so that cavities generated in a coating process is reduced, and the self-curing insulating material is uniformly attached to the joints of the electric wires.

Abstract: A utility vehicle for power emergency repair includes a cab, a carriage and a lighting device, including mounting bases, a wire pole, a rotary base and a lamp assembly. A rotary shaft is bridged between the mounting bases, and the rotary base is fixedly connected to the rotary shaft. First and second positioning units are provided on the top of the carriage. The rotary base has first and second positioning surfaces, the first positioning unit includes a first limiting platform, and the second positioning unit includes a rotation limiting plate and positioning plates. The positioning plates is supported on a lower end surface of the rotation limiting plate. The utility vehicle further includes a driving assembly and first and second contacts. A trigger signal is generated and the driving assembly is controlled to release braking on the rotary shaft when the first and second contacts contact each other.

Abstract: The invention claims an engine surge fault prediction system and method based on fusion neural network model, belonging to the technical field of time series data prediction. The system comprises a prediction module, used for generating prediction time series with a specified length through 3D structure time series data of the engine; a feature extraction module, used for extracting the local features of the prediction time series, semantic relations among data, and overall trend features of the series; a classification module, used for judging if there is a surge fault according to the local features of the prediction time series, semantic relations among data, and overall trend features of the series.
