Description

Technical Field

[0001] The present invention relates to the field of electromagnetic launch; specifically, it relates to an integrated module structure of an electromagnetic launch coil. Background Art

[0002] As a system that converts electrical energy into the kinetic energy of a load, an electromagnetic coil gun consists of multiple groups of electromagnetic launch coil modules, multiple groups of high-power pulsed capacitor modules, multiple groups of power switch tube modules, and control equipment. The control equipment controls multiple power switch tube modules to be turned on at different times. The electrical energy in the high-power pulsed capacitor module enters the corresponding electromagnetic launch coil module through the corresponding power switch tube, so that the electrical energy is converted into the kinetic energy of the load, realizing electromagnetic launch. The electromagnetic launch coil is composed of multiple groups of coil modules connected in series. Each group of coil modules must be connected in series with a group of power switch tubes and a group of high-power pulsed capacitors to form a discharge circuit.

[0003] In common coil guns, the coil modules, power switch tubes, and high-power pulsed capacitors are arranged independently and separately, and are connected by discharge wires. Since the traditional coil gun system disperses the electromagnetic launch coil, high-power pulsed capacitor, power switch tube, and control equipment and connects them through discharge wires in the middle, the coil gun system is bulky, occupies a large space, has a large number of discharge wires, and a conductive slip ring needs to be set when the coil gun performs pitching or slewing functions, resulting in poor equipment reliability; in order to aim at the shooting target, the electromagnetic launch coil after cascading multiple groups of coil modules needs to perform slewing and pitching, and the discharge wires between the coil and the high-power pulsed capacitor seriously affect the flexibility of the electromagnetic gun's pitching and slewing. Summary of the Invention

[0004] In order to meet the requirements of a small volume of the coil gun system, cancel the discharge loop wires or cancel the conductive slip ring at positions where there is a degree of freedom of movement, and solve the problem of the non-compact structure caused by the dispersed arrangement of the traditional electromagnetic launch coil, high-power pulsed capacitor, and power switch tube, the present invention proposes a new electromagnetic coil gun structure that integrates the electromagnetic launch coil, high-power pulsed capacitor, and power switch tube into one.

[0005] The object of the present invention is achieved in the following manner:

[0006] An integrated module structure of an electromagnetic launch coil, comprising a support tube, a coil module, a capacitor, an inner adhesive material layer, a power switch tube, and an outer adhesive material layer. The coil module is wound around the support tube, and the coil module and the support tube are cured into an integral inner layer of the coil gun module through the inner adhesive layer; the two electrode layers and the insulating layer of the capacitor are wound around the circumferential surface of the integral inner layer of the coil gun module, and two capacitor electrode wires are provided. The power switch tube is sleeved on the outer surface of the capacitor, and the two electrodes of the power switch tube are respectively connected to the capacitor electrode wires. The two electrodes of the coil module are respectively connected to the corresponding electrodes of the power switch tube; through overall perfusion encapsulation with the outer adhesive layer, an integrated electromagnetic coil gun module is formed.

[0007] The coil of the coil module is a copper wire, an aluminum wire, or a copper-aluminum composite wire.

[0008] The support tube is made of a non-conductive and non-magnetic material, including one or several materials such as glass fiber, carbon fiber, resin, plastic, or ceramic.

[0009] The inner adhesive material layer is made of a non-magnetic material with adhesiveness, including epoxy resin.

[0010] The power switch tube is a thyristor or a diode.

[0011] The beneficial effects of the present invention: The integrated electromagnetic coil gun module cleverly combines a single-stage launch coil, a single-stage pulsed high-power capacitor, a single-stage control power switch tube, and a discharge wire, realizing the integration from the dispersed layout of the single-stage launch coil, the single-stage pulsed high-power capacitor, the single-stage control power switch tube, and the discharge wire to the overall integration, forming a single-stage integrated electromagnetic coil gun module, canceling the discharge wire in the discharge loop of the pulsed capacitor - electromagnetic launch coil - power switch tube in the composition of the first-stage coil gun, achieving high integration and integration, and solving the problem of difficult layout due to the thick diameter of the discharge wire.
