The invention provides a millisecond-level fast reconfiguration method and system for a power supply network after a power grid fault. Fast network reconfiguration The main station collects grid status information from substations or substations of power plants, and compares it with the built-in control strategy table that may fail; The corresponding sub-station sends a closing pre-start signal; when the fault is cleared, the sub-station identifies the clearing time according to the local information, and sends a detection synchronous closing signal to the corresponding local recovery network circuit breaker; at the same time, the main station independently monitors To clear the fault, send a backup inspection synchronous closing signal to the corresponding recovery network circuit breaker, based on the above mechanism, the disconnected power grid will be re-connected to the grid within 150ms after decommissioning. After the power grid is restored to interconnection, the circuit breakers forming the electromagnetic ring network are opened.

The invention provides a shield construction system, which includes a shield receiving shaft and a turn-back belt conveyor assembly, wherein the shield receiving shaft is arranged on the tunneling route of the shield machine, and in the direction of tunneling of the shield machine, the shield The first tunnel and the second tunnel are respectively formed on both sides of the machine receiving shaft, and the shield receiving shaft is used to initiate the second shield machine and receive the first shield machine; at least a part of the return belt conveyor assembly is arranged in the second tunnel , to be used to automatically transport the muck produced by the second shield machine to the ground when excavating the second tunnel; in the direction of shield machine excavation, the width of the part of the return belt conveyor assembly located in the shield receiving shaft is the same as The ratio of the width of the shield receiving well is greater than 0 and less than or equal to 30%. The invention solves the unreasonable layout of the belt conveyor and the receiving shaft of the shield machine in the prior art, which causes the shield machine to be unable to be received normally, slows down the progress of the shield machine construction, prolongs the construction period of the shield machine, and improves the construction efficiency of the shield machine. The cost of shield construction.

The invention discloses a nasogastric feeding tube body device which can conveniently monitor the temperature of liquid food. The bottom of the second hollow rectangular tube is fixedly connected with a food inlet, the outside of the food inlet is fixedly connected with an external thread, the external thread is fixedly connected with a connecting pipe, and one side of the connecting pipe is provided with a water and food inlet , baffles are fixedly connected on both sides inside the main body of the pipeline connection device. The present invention communicates with the main body of the pipeline connection device by setting the first hollow rectangular tube and the second hollow rectangular tube, and can connect two pipelines at the same time. The liquid food and water can be entered respectively, and the infusion pipeline can be connected through the set feeding port and the connecting pipe, and the connecting pipe can be easily disassembled in time through the set external thread, and the pipeline can be replaced conveniently.

The invention discloses a charging base with a conductive needle, which includes a body, and a conductive needle telescopically positioned on the body through an elastic mechanism. The conductive needle forms a charging electrode, and the part protruding from the body is at least as high as The distance between the main unit and the main body when charging, after pressing, the conductive needle is supported by the elastic mechanism, and keeps in pressure contact with the charging electrode on the main unit. In this application, the conductive needle is used as the charging electrode to contact the charging electrode of the host for charging. Since the conductive needle is telescopically positioned on the body through the elastic mechanism, the elastic mechanism shrinks under pressure during charging, keeping the pressure contact between the conductive needle and the charging electrode on the host. , to ensure effective contact between the charging electrodes of the host and the charging stand during charging, and improve stability.
