when a person is required to balance the weight of the person falling by sliding down onto the liferaft 2, it may be divided into three parts:
1. when the gravity difference between the two persons is not much, the driving motor 43 always keeps rotating forward, so that the driving motor 43 drives the sixth connecting shaft 46 to rotate, and therefore drives the third gear 23 to rotate, and therefore drives the second gear 22 to rotate, and further drives the first gear 21 to rotate, when the first gear 21 and the second gear 22 rotate, the third connecting shaft 19 and the fourth connecting shaft 20 will be driven to rotate, because the third gear 23 rotates forward, the second gear 22 will be driven to rotate backward, and therefore the first gear 21 will be driven to rotate forward, and therefore when the fourth connecting shaft 20 rotates backward and the third connecting shaft 19 rotates forward, because of the action of the limiting block 24 and the movable block 25, the second belt pulley 17 and the third belt pulley 18 will be driven to rotate when the third connecting shaft 19 and the fourth connecting shaft 20 rotate, and then the first belt 16 drives the two sets of first belt pulleys 15 to rotate, the first belt pulley 15 connected with the second belt pulley 17 is rotated forward, the first belt pulley 15 connected with the third belt pulley 18 is rotated backward, thereby driving the two sets of second connecting shafts 14 to rotate, namely forward rotation and reverse rotation, when the second connecting shafts 14 rotate, the pinions 30 will be driven to rotate, and the second bevel gears 13 will be driven to rotate, and further, the first bevel gear 12 is rotated by the second bevel gear 13, thereby rotating the first connecting shaft 10, thereby driving the first propeller 11 to rotate, when the propeller rotates, the propeller generates upward force through the action of water, thereby balancing the falling gravity of the personnel and further achieving the balancing effect, when the pinion 30 rotates, the first gearwheel 31 will be driven to rotate, due to the action of the ratchet wheel 33 and the pawl 34, the large gear does not transmit power downwards, so that the rotation of the two groups of first propellers is not influenced;
2. when the gravity of one side is large, the rotating speed of the driving motor 43 is increased at the moment, and then the driving motor 43 drives the second propeller 47 to rotate, so that a large force is generated between the second propeller 47 and the water, and the generated force is larger than the pulling force of the tension spring 44, so that the driving motor 43 is pulled to move, and further the second gearwheel 48 is driven to move, after the second gearwheel 48 moves, the second gearwheel 48 is meshed with the rack 55, and at the moment, the second gearwheel 48 moves rightwards under the condition of being meshed with the rack 55;
through the reverse rotation of the driving motor 43, at the moment, through the action of the spring and the movable plate 51, the threaded groove 52 is in threaded connection with the third fixed seat 53, so that the driving motor 43 is driven to move forward, and meanwhile, the second gearwheel 48 is driven to move forward and further to be meshed with the rack 55, due to the reverse rotation of the driving motor 43, the second gearwheel 48 is driven to move leftward, due to the reverse rotation of the driving motor 43, the third flat gear 23 is driven to rotate reversely, the second flat gear 22 is driven to rotate forward, and the first flat gear 21 is driven to rotate reversely, at the moment, due to the action of the limiting block 24 and the movable block 25, the second belt pulley 17 and the third belt pulley 18 cannot rotate at the moment, and further, transmission interference cannot occur;
when the second gearwheel 48 moves to the left and right ends of the rack 55 in the leftward or rightward direction, the limiting member 56 will stop the movement of the second gearwheel 48, and when the second gearwheel 48 moves in the leftward or rightward direction, the third pinion 23 is disengaged from the second pinion 22, so that the first propeller 11 will not be driven to rotate by the second pinion 22 and the first pinion 21, and no transmission interference will occur, and at this time, the second gearwheel 48 is just engaged with the first gearwheel 31, and the first gearwheel 31 is driven to rotate, and the pinion 30 is driven to rotate, so as to drive the second connecting shaft 14 to rotate, and when the second gearwheel 48 rotates, the fifth connecting shaft 37 will be driven to rotate by the action of the ratchet wheel 33 and the pawl 34, and the fourth belt pulley 38 will be driven to rotate, so that the fifth belt pulley 39 fixedly connected to another set of second connecting shafts 14 will be driven to rotate by the action of the second belt 40, and then drive another group of second connecting shafts 14 to rotate, at this moment, the second connecting shaft 14 will drive the pinion 30 fixedly connected with it to rotate, and then drive another group of first bull gears 31 to rotate, because another group of ratchet gears 33 and pawls 34 and the previous group of ratchet gears 33 and pawls 34 are mirror images, and then will not drive the fifth connecting shaft 37 fixedly connected with it to rotate, so no transmission interference occurs, when two groups of second connecting shafts 14 rotate, will drive the first connecting shaft 10 and the first propeller 11 to rotate through the meshing of the first bevel gear 12 and the second bevel gear 13, because the first bull gear 31 drives the pinion 30 to rotate, so will increase the rotational speed of the pinion 30, and then increase the rotational speed of the second connecting shaft 14, and thus increase the rotational speed of the first propeller 11, and then provide the ground force to be bigger, and another group of second connecting shafts 14 rotates the same as the first bull gear 31, therefore, the second large gear 48 is engaged with the first large gear 31 on which side, the rotating speed of the first propeller 11 on which side is higher than that of the first propeller 11 in the other group, so as to balance the unequal gravity on the two sides;
3. when the two sides accelerate and the gravity of the two sides are equal, the rotation speed of the driving motor 43 is restored to the initial state and rotates forward, and the tension spring 44 pulls the driving motor 43, so that the second large gear 48 and the rack 55 are disengaged, meanwhile, the third flat gear 23 is engaged with the second flat gear 22, and the rotation speeds of the first propellers 11 on the two sides are equal;
in the present embodiment, the weight of the person on both sides is detected by the pressure sensors provided on the slide 5.
