The electromagnetic shielding layer 72 mainly plays a role in shielding external interference and protecting, and the outermost hydrophobic coating can be coated by fluorocarbon paint, organic silicon and other coatings, mainly in order to increase the contact angle between the outer surface and water drops, so that the water drops are not easy to stay on the outer surface, and the probability of the water drops permeating into the composite material substrate is greatly reduced; the substrate layer can be made of composite materials made of A-151 and Wolland treated glass fibers, mainly plays a role in moisture resistance and heat resistance, and can also keep good conductivity per se; the hydraulic ring is arranged to avoid that the material deformation generated by cold and hot stress damages the structure in the shielding layer, so that the performance of the shielding layer is reduced and even damaged, and mainly to weaken the influence of the stress on the internal structure of the base layer, the hydraulic ring is selected according to actual conditions, if the accelerated emission carrier 8 is not large in quality, low in bore discharging speed, small in required driving magnetic field and the like, the generated stress is small, the hydraulic ring is not needed to be arranged, otherwise, the hydraulic ring needs to be arranged, and otherwise, the electromagnetic shielding layer 72 can be deformed and even broken, and cannot work normally; the ceramic insulating layer and the magnetic field shielding layer mainly play a role in blocking an internal magnetic field and an external magnetic field in order to ensure that the external magnetic field cannot interfere with the magnetic field inside the guide rail and that the magnetic field inside the guide rail cannot cause harm to external equipment or human bodies, and the like, wherein the magnetic field shielding layer is made of metal such as iron, nickel, chromium, cobalt and the like and compound materials thereof.

Furthermore, the main power supply bank 1 and the guide rail power supply bank 6 are powered by batteries. The main power supply base 1 is mainly used for supplying power to all modules of the electromagnetic gun, the guide rail power supply base 6 is mainly used for supplying power to the guide rail main body 7 and serving as a standby power supply base, and when the electromagnetic gun is used, the electromagnetic gun is set according to actual conditions, if power is supplied for a short time and the requirement on a launching task is not high, the guide rail power supply base 6 can be omitted, and power can be directly supplied through the main power supply base 1; if necessary requirements such as ultra-long-time power supply and fixed-position use are needed, the main power supply bank 1 can be changed into 220V mains supply for direct power supply, and only a matched voltage and current control circuit needs to be added.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
