The power in the acceleration process comes from the electromagnetic force between the acceleration module consisting of the electromagnetic module and the ejection trailer, and in order to avoid speed loss caused by electromagnetic repulsion, the acceleration trailer and the conductive bars form an intermittent electrifying system to realize intermittent acceleration. The electromagnetic repulsion is prevented from generating adverse effects on the acceleration process through intermittent acceleration and mutual conversion between the ejection trailer and the acceleration module, and meanwhile, the movement displacement of the ejection trailer after the ejection is finished is reduced;
at the tail end of the ejection track, the ejection trailer enters the acceleration track to be converted into an acceleration module, and the acceleration module at the starting point of the acceleration track enters the ejection track to be converted into the ejection trailer; the synchronous power-on and synchronous power-off of the acceleration modules and the ejection trailer at different positions are realized by the dislocation of the same group of wires on the wire row on the acceleration track and the ejection track. The catapult trailer comprises a left electromagnetic module and a right electromagnetic module, the electromagnetic polarities of the left electromagnetic module and the right electromagnetic module are opposite, and synchronous motion of the two catapult trailers is realized through homopolar repulsion and heteropolar attraction in a magnetic field.

The number of the accelerating tracks 1 and the number of the ejection tracks 2 are two respectively, wherein the two accelerating tracks 1 are located on two sides of the tracks, and the two ejection tracks 2 are located in the centers of the tracks.
2) The conducting bar is a flat plate consisting of conductors, is flatly laid on the surface of the track and provides electric energy for the electromagnetic module, and is divided into a positive terminal 6, a negative terminal 7, an accelerating track left contact 8, an accelerating track right contact 9, an ejection track left contact 10 and an ejection track right contact 11, wherein the positive terminal 6 is used for positive level input, the negative terminal 7 is used for negative level input, the conducting bars on the two sides of the contacts 8, 9, 10 and 11 are switched on when the electromagnetic module passes through, and the two sides of the contacts form a passage. In the conductive row, the adjacent ejection track left contact 10 and the ejection track right contact 11 are connected, each contact comprises a positive contact and a negative contact, and the contacts are grouped in pairs.
3) The electromagnetic module is composed of energized solenoids, and structurally comprises a magnet 12, a contact rod 13, spherical wheels 14 and a towing hook 15, wherein the electromagnetic module exists as a left acceleration module 16 and a right acceleration module 17 when being on an acceleration track, and exists as a left ejection trailer 18 and a right ejection trailer 19 when being on an ejection track, the magnetic polarities of the left acceleration module and the right acceleration module are opposite to those of the left ejection trailer and the right ejection trailer, two front wheels in 4 spherical wheels are connected by a lead, two rear wheels are connected by a lead, the front wheels are used as the power supply anode of an electromagnet in the magnet, and the rear wheels are used as the cathode of the electromagnet 17 in the magnet.

4) The positive terminal 6 and the negative terminal 7 which are arranged on the track and are connected with the conducting bar are arranged at intervals in a belt shape, and whether the circuit is conducted or not is determined by the movement position of the acceleration trailer, so that the movement of the acceleration trailer on the acceleration runway can enable the electromagnetic modules to be electrified discontinuously, the electromagnetic repulsion can be avoided by the discontinuous electrification, and the acceleration trailer can be in an inertia sliding state when the acceleration trailer moves in an electrodeless area between the belt-shaped positive terminal 6 and the negative terminal 7.
The control principle of the intermittent acceleration type electromagnetic ejection device is as follows:
in the initial stage of acceleration, the left catapult trailer 18 and the right catapult trailer 19 are located at the initial position of the catapult track 2, the spherical wheel 14 of the left catapult trailer 18 is pressed on the acceleration track left contact 8 and the catapult track left contact 10 at the same time, the spherical wheel 14 of the right catapult trailer 19 is pressed on the acceleration track right contact 9 and the catapult track right contact 11 at the same time, because the inside of 2 front wheels and 2 rear wheels of the four spherical wheels 14 are connected by wires, the first group of wires of the wire row is conducted, and the electric potential difference exists at the two ends of the left acceleration module 16 and the right acceleration module 17 on the conducted wire row, the inside of the left catapult trailer 18 and the right catapult trailer 19 is also electrified to generate a magnetic field, the polarities of the left catapult trailer 18 and the right catapult trailer 19 are opposite, the polarities of the magnetic fields of the left acceleration module 16 and the right acceleration module 17 are opposite, the generated magnetic fields are as shown in fig. 8, wherein N represents S, S represents S, at this time, the left catapult trailer 18 and the right catapult trailer 19 are subjected to the attraction force of the left catapult trailer 19 and the left catapult trailer 19 are subjected to move synchronously.
As the left and right catapult trailers 18, 19 move forward, the distance from the N pole of the left catapult trailer 18 to the N pole of the left acceleration module 16 is less than the distance from the S pole of the left acceleration module 16, the attraction force of the left and right acceleration modules 16, 17 to the left and right catapult trailers 18, 19 becomes a repulsive force, but the moving left and right catapult trailers 18, 19 have passed the wire row, the circuit is not conducted, the magnetic field disappears, and the left and right catapult trailers 18, 19 will slide in inertia until reaching the next set of left and right acceleration rail contacts 8, 9 and left and right catapult rail contacts 10, 11, at which point the process will repeat.
When the left and right catapult trailers 18 and 19 reach the end point of the catapult runway 2, the left and right catapult trailers 18 and 19 are separated under the restraint of the forked guide track 3, move to the extension lines of the two acceleration tracks 1 respectively and finally stop at the end point cart 4, at the moment, the end point cart 4 pushes the left and right catapult trailers 18 and 19 to move to the starting point along the acceleration tracks 1 and pushes all the acceleration modules to move when the left and right catapult trailers 1819 contact the left and right acceleration modules 16 and 17 at the end point, the contact rod 13 plays a role in transferring the power of the motion at the moment, when the left and right acceleration modules 16 and 17 at the starting point are pushed by the contact rod 13 to reach the position of the starting point cart 5, the starting point cart 5 pushes the right acceleration modules 16 and 17 to move in the direction perpendicular to the catapult runway 2, at the moment, the catapult reaches the position of the left and right catapult trailers 18 and 19 at the initial time, at the moment, the electromagnetic modules which originally serve as the left and right acceleration modules 16 and 17 at the starting point are converted into the end point of the left and right catapult trailers 18 and 17 without the start point, so that the whole catapult trailer 18 and 19 can be directly returned to the starting point without the start point, thereby greatly shortening of the catapult trailer 18 and the catapult trailer
In summary, the invention is an intermittent electromagnetic catapult, the catapult power is from electromagnetic force, but the catapult trailer and the accelerating module providing the catapult power are completely consistent, so after one catapult cycle is completed, the catapult trailer directly enters the terminal of the catapult track to become the accelerating module, the accelerating module at the starting point enters the catapult track to become the catapult trailer, and the discontinuous conduction of the circuit is realized through the cooperation of the catapult trailer and the lead wire row, thereby avoiding the adverse effect of electromagnetic repulsion force on the accelerating color generation of the catapult trailer. After the ejection process is finished, the ejection trailer does not need to return to the ejection starting point, so that the moving distance and the preparation time of the ejection trailer in the preparation process are reduced.
