Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: an electromagnet-based self-propelled mechanism comprises a rear vehicle body 1 and a front vehicle body 2,

The utility model discloses from running gear's based on electro-magnet working process as follows: first on the front body 2, in particularIs thatA mechanism capable of cleaning a scale layer, such as a grinding machine, is arranged on a second front frame 11 on the front vehicle body 2, then the mechanism is arranged on the outer shell of the ship body, and the mechanism is started, so that the mechanism can start to work under the control of a preset program;

in an initial state, the electromagnets 16 in the two sets of electromagnet mechanisms are electrified and show magnetism, and the two electromagnets 16 are adsorbed on the hull shell to fix the mechanism; after the rear vehicle body 1 starts to work, the electromagnet 16 on the rear vehicle body 1 loses power, the motor 5 works and drives the driven tooth 7 and the screw 8 to rotate through the driving tooth 6, and the screw 8 and the screw seat 13 are in threaded connection at the other end, so that the screw and the screw transmission pair can pull the rear vehicle body 1 to move towards the front vehicle body 2;

after the rear vehicle body 1 moves to a position close to the front vehicle body 2 (the movement distance of the vehicle body can be controlled by controlling the revolution of the motor 5), the electromagnet 16 on the rear vehicle body 1 is electrified to adsorb the rear vehicle body 1 on the hull shell, and the electromagnet 16 on the front vehicle body 2 is electrified, so that the front vehicle body 2 recovers the degree of freedom, and the motor 5 rotates reversely for the same revolution to push the front vehicle body 2 to move towards the direction far away from the rear vehicle body 1;

the working process of the electromagnet mechanism is as follows: the electromagnet 16 shows magnetism after being electrified, under the action of the magnetic force, the electromagnet 16 moves towards the direction of the ship shell and is finally adsorbed on the shell of the ship, and all the springs 15 are compressed at the moment; the electromagnet 16 is no longer magnetic after power failure, under the action of the spring 15, the electromagnet 16 moves reversely and returns to the initial position, and at the moment, the rear wheel 4 or the front wheel 12 can rotate; in the process, the guide post 18 and the guide groove 17 slide relatively to play a role in guiding;

the stepping type advancing of the mechanism can be realized by repeating the circulating action according to the mode; in the advancing process, the automatic cleaning mechanism arranged on the front vehicle body 2 can clean the hull shell;

in the whole working process, the mechanism always ensures that at least one electromagnet is in an electrified state, so the mechanism can be always attached to a hull shell; that is, the mechanism can work normally no matter where the mechanism is positioned on the hull shell, and can work normally even if the mechanism is in an inverted state; when the mechanism is in an inverted state, the buoyancy tank 19 can provide buoyancy force with one direction always upward for the device, and the buoyancy force can enable the device to be tightly pressed on a hull shell and act together with the two electromagnets 16 to ensure the cleaning effect;

the front vehicle body 2 in the mechanism consists of a first front frame 10 and a second front frame 11 which are hinged with each other, and the structure can ensure that the self-propelled mechanism can still realize better fixation and attachment when meeting a non-planar hull shell, thereby ensuring the walking effect of the mechanism;

because the maximum buoyancy that two flotation tanks 19 can provide is greater than this self-propelled mechanism's gross weight power, therefore after some shell cleaning work, through control system control two electro-magnets 16 lose the electricity, under the buoyancy that flotation tanks 19 provided, whole mechanism floats to the surface of water, and the operator only need salvage it up, and reset on the position that next needs shell cleaning, carry out next part shell cleaning work.

The control system used in the mechanism can preset corresponding programs to control each actuating mechanism, and can also be provided with a module capable of realizing wireless data transmission, and sends signals to the control system through a wireless network to control the mechanism in real time. In any case, the program or software preset in the control system is implemented by those skilled in the art through the existing technical means.
