Description
Technical Field
[0001] The invention relates to a fast horizontally movable propulsion device based on the eddy current repulsion principle, belonging to the technical field of switch equipment and control. Background Art
[0002] In recent decades, as missiles have become more and more sophisticated, the requirements for various trigger devices have become higher and higher. They are not only required to be small in size and move quickly, but also to generate at least tens of kilonewtons of thrust. Therefore, in order to solve the above problems, the key to achieving fast and powerful impact lies in the research on horizontally movable propulsion devices. Among them, the power source of the missile trigger operation is the operating mechanism, and the impact force generated by its action determines the accuracy of the missile trigger. The most widely used operating mechanism in the field of fast switching is the electromagnetic repulsion mechanism based on the eddy current repulsion principle. The eddy current repulsion mechanism has a simple structure, extremely short repulsion formation time and action response time, large initial acceleration, and can effectively achieve rapid closing and separation. However, it is difficult to achieve that when the volume required by the structure is very small, it can also meet the various requirements of the missile trigger device. At present, there is an urgent need for a propulsion device with short response time, fast action speed, strong thrust generation, and flexible drive. Summary of the invention
[0003] The purpose of the present invention is to solve the above problems and provide a fast horizontal moving propulsion device based on the eddy current repulsion principle which has a simple structure, is easy to adjust, has a small size and generates large thrust.
[0004] The invention discloses a fast horizontally movable propulsion device based on the eddy current repulsion principle, which is realized in this way and comprises a fixed disk, a coil disk, a repulsion disk, a connecting spring, a connecting rod, a shaft rod and an umbrella buckle structure.
[0005] The fixed plate, coil plate and repulsion plate form a set of eddy current systems. Each set of eddy current systems is fixed by a connecting rod so that the plate surface is perpendicular to the shaft rod. The coil plate is located between the repulsion plate and the fixed plate with a gap, and is installed on the shaft rod that can move horizontally left and right to keep relatively still.
[0006] The present invention provides a fast horizontally movable propulsion device based on the eddy current repulsion principle, which also includes a spring system and a support system. The spring is installed between two adjacent groups of eddy current systems to prevent collision. The shaft rod is arranged horizontally and an umbrella buckle structure is fixedly installed on its surface. The force exerted on the repulsion plate is transmitted to the umbrella buckle structure, and the force is applied to the umbrella buckle structure, thereby driving the shaft rod to move horizontally. The umbrella buckle structure can slide and shrink, and its initial state is to open outwards. The shaft rod is driven to move by the compression of the repulsion plate. After generating its own speed, it will continue to move forward due to inertia. Without the compression of the repulsion plate, the umbrella buckle structure shrinks, making the surface of the shaft rod smooth.
[0007] Among them, due to the existence of a spring system between the repulsion plate and the coil disk, the repulsion plate and the coil disk always maintain relative horizontal movement during operation. The fixed plate, the coil disk and the repulsion plate are fixedly connected by a connecting rod to prevent the disc from rotating, forming an eddy current system. The coil disk and the repulsion plate slide on the shaft. When the external circuit energizes the coil disk, the eddy current repulsion generated can provide a very considerable thrust. As the distance between the magnets of the coil disk and the repulsion disk decreases, and through the mutual superposition of multiple groups of structures, the repulsion increases exponentially, which means that when the volume required by the structure is very small, the use of a fast horizontally moving propulsion device based on the eddy current repulsion principle can meet the various requirements of the missile trigger device.
[0008] The shaft is fixed with umbrella buckle structures around it, which are fixed on the side wall of the shaft so that they can shrink automatically, and a set gap is left between each umbrella buckle structure. The eddy current system can be slidably sleeved on the shaft, and can apply force to the shaft under the action of the umbrella buckle structure.
[0009] A circular hole with a diameter smaller than the diameter of the shaft rod and smaller than the diameter of the coil is reserved at the center of the connecting rod.
[0010] The working mechanism of the present invention is:
[0011] By controlling the external circuit of the coil disk, the energy storage capacitor controls the discharge time of the coil disk. The magnetic field generated by the coil generates eddy current repulsion on the metal repulsion disk to provide thrust. When the repulsion disk is subjected to force, the umbrella buckle structure outside the shaft rod bulges, and the thrust to the left by the repulsion disk drives the shaft rod to move horizontally, thereby achieving the purpose of the shaft rod pulling the fuse. Due to inertia, when the umbrella buckle structure loses contact with the repulsion plate, the umbrella buckle will shrink by itself. Due to the existence of the spring structure, a certain gap can be maintained between each set of eddy current systems. The connecting rod keeps the coil disk and the repulsion disk relatively still, and no angle deviation occurs.
[0012] Furthermore, the force applied to the shaft increases exponentially with the increase of the eddy current group. The number of coils wound around the coil disk is directly related to the thrust applied to the repulsion disk. The more coils there are, the stronger the magnetic field strength is, and the more significant the eddy current effect is. Therefore, if the structure and function allow, the number of coils wound around the coil disk and the number of eddy current system groups can be set according to the needs of use to generate the required thrust.
[0013] The beneficial effects of the present invention are:
[0014] The fast horizontally movable propulsion device of the present invention based on the eddy current repulsion principle can generate a large thrust while meeting the requirement of a small volume, which is specifically embodied in the following aspects:
[0015] 1) The eddy current between the coil disks is used to provide repulsion, and the repulsion increases exponentially with the increase of the eddy current group, which has outstanding advantages over the traditional structure;
[0016] 2) With a relatively small volume, it can still generate a large range of thrust in a short time and has a wide range of applications;
[0017] 3) The structure used is simple, the loss is small, the performance is more stable, and the maintenance is more convenient.
[0018] In summary, the fast horizontally movable propulsion device based on the eddy current repulsion principle of the present invention has the advantages of simple structure, convenient adjustment, and the ability to generate a wide range of thrust. Compared with the shortcomings of traditional propulsion devices, the fast horizontally movable propulsion device based on the eddy current repulsion principle is an ideal alternative. It has a higher cost-effectiveness and can be widely used in missile fuze triggering systems, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the working principle of the present invention more clear, the present invention is described in conjunction with pictures, but the present invention is not limited to this embodiment.
[0027] like Figure 1-Figure 3 The present invention provides a fast horizontally movable propulsion device based on the eddy current repulsion principle, comprising a fixed disk A, a repulsion disk B, a coil disk C, a connecting spring D, a connecting rod E, a shaft rod F, and an umbrella buckle structure G.
[0028] The fast horizontally movable propulsion device based on the eddy current repulsion principle includes an eddy current system. The eddy current system includes a fixed disk A, a repulsion disk B and a coil C. The three are fixedly connected to a shaft that can move horizontally left and right through a connecting rod E. At the same time, the plate surface of the coil disk and the repulsion plate is set perpendicular to the shaft. The three move relative to each other to form a set of eddy current system modules. The coil is wound on the coil disk as shown in FIG. Figure 3 As shown, through this connection method, a set of coil disks of the eddy current system can generate a large thrust. By superimposing multiple sets of systems, the magnitude of the force increases exponentially. The magnitude of the thrust can be controlled according to the required number of coil groups and the distribution method.
[0029] The fast horizontally movable propulsion device based on the eddy current repulsion principle also includes a spring system. The spring system includes a connecting spring and a connecting rod, the connecting spring is sleeved on the adjacent eddy current system, the fixed end of the connecting spring is fixed to the left eddy current system, and the free end is fixed to the adjacent right eddy current system, and the connecting rod is sleeved on the eddy current system and penetrates and connects all the eddy current systems in the horizontal direction to keep their relative positions unchanged.
[0030] The fast horizontal moving propulsion device based on the eddy current repulsion principle includes a support system, which is composed of a shaft and an umbrella buckle structure. The shaft is horizontally arranged and the umbrella buckle structure is fixedly installed on the surface of the shaft.
[0031] In this embodiment, the discharge time of the coil disk is controlled by controlling the external circuit of the coil disk, and the magnetic field generated by the coil generates an eddy current effect on the metal repulsion disk to provide thrust. Figure 2 As shown, a stopper with an umbrella buckle structure is arranged on the outside of the shaft rod. The initial position of the stopper of the outer umbrella buckle structure is unfolded and protrudes outside the shaft rod, and the repulsion plate is in close contact with it. The shaft rod is driven by the extrusion of the repulsion plate, and after generating speed, it will continue to move forward due to inertia. Without the extrusion of the repulsion plate, the umbrella buckle structure shrinks, making the surface of the shaft rod smooth. When the coil disk is energized, each group of four umbrella buckle structures evenly fixed on the outer tube of the shaft rod unfolds, and the generated force is applied to the umbrella buckle structure, pushing the shaft rod to move horizontally.
[0032] Due to the existence of the spring structure, a certain gap can be maintained between each set of eddy current systems, and the connecting rod keeps the coil disk and the repulsion disk relatively still without angular deviation.
[0033] In this embodiment, the force applied to the shaft increases exponentially with the increase of eddy current groups, and is related to the number of coil groups on the coil disk and the winding method.
[0034] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
