When the gate needs to be maintained, a diver carries the device to submerge into a position to be maintained, the device is fixed on the gate through the electromagnet 18, the position to be maintained is positioned at the left side of the motion cavity 44, the second motor 31 is started, the second motor 31 works to drive the driving shaft 28 and the fourth bevel gear 29 and the third bevel gear 25 on the driving shaft 28 to rotate, the third bevel gear 25 rotates to drive the second bevel gear 23 meshed with the third bevel gear to rotate, so as to drive the rotating shaft 24 and the rotating gear 22 on the rotating shaft 24 to rotate, the rotating gear 22 rotates to drive the moving block 26 meshed with the rotating shaft through the rack 27 to move leftwards, so as to drive the sealing block 12 to move leftwards, the sealing block 12 moves leftwards to drive the sealing ring 14 to move leftwards and abut against the gate, after the sealing ring 14 is tightly sealed with the end face of the gate, the sealing block 12 continues to, at this time, the pumping port 45 is communicated with the communication channel 50, the floating plate 51 moves upwards under the buoyancy of water to release the pulling rope 71, the movable block 100 loses the upward movement under the action of the pulling force of the pulling rope 71, the locking rod 79 abuts against the lower end of the fixed rod 77, when the sealing ring 14 is sealed with the gate and moves rightwards, the fixed rod 77 is pushed to move rightwards, so as to drive the locking rod 79 entering the clamping groove 76 to move rightwards, the locking rod 79 moves rightwards to drive the displacement block 72 to move rightwards and tension the rope 57, the sliding gear 55 moves upwards under the action of the pulling force of the rope 57 to be meshed with the driving gear 60, the first motor 63 is started, the first motor 63 works to drive the driving shaft 62 and the driving gear 60 and the driving gear 95 on the driving shaft 62 to rotate, the driving gear 60 rotates to drive the sliding gear 55 meshed with the driving gear to, the reel 61 rotates to tighten the chain 67, the baffle 49 moves rightwards under the action of the tension of the chain 67 and opens the communication channel 50, the driving pulley 65 rotates to drive the driven pulley 46 which is in transmission connection with the driven pulley 46 to rotate, so as to drive the fan shaft 47 and the fan blade 48 on the fan shaft 47 to rotate, the fan blade 48 rotates to draw water in the motion cavity 44 away, after the water in the motion cavity 44 and the communication channel 50 is completely drawn away, the floating plate 51 loses the buoyancy effect of the water to move downwards to tighten the pull rope 71, the movable block 100 and the locking rod 79 move downwards under the tension of the pull rope 71 to reset, the displacement block 72 loses the limit of the locking rod 79 and moves leftwards under the action of the tension of the second spring 85 to reset, the rope 57 is loosened, the sliding gear 55 moves downwards under the tension of the rope 57 to disengage with the driving gear 60, the baffle 49 moves leftwards under the action of the elasticity of the pressure spring 68 to close the communication channel 50 again, thereby forming the moving chamber 44 as a water-free sealed space; when the gate is subjected to rust removal, the driving gear 95 rotates to drive the gear shaft 35 meshed with the driving gear to move leftwards, so that the grinding block 89 at the left end of the moving shaft 11 and the moving shaft 11 is driven to move leftwards, after the grinding block 89 moves leftwards and is contacted with a part to be subjected to rust removal of the gate, the driving gear 95 just rotates to a position where the driving gear is separated from the gear shaft 35, the moving shaft 11 and the grinding block 89 stop moving leftwards continuously, the fourth bevel gear 29 rotates to drive the fifth bevel gear 32 meshed with the fourth bevel gear to rotate, so that the rotating shaft 33 and the first bevel gear 34 at the lower end of the rotating shaft 33 are driven to rotate, the first bevel gear 34 rotates to drive the sliding bevel gear 41 meshed with the first bevel gear to rotate, so that the moving shaft 11 and the grinding block 89 are driven to rotate; when carrying out the touch-up paint to the gate again, start first motor 63 and reverse, thereby drive removal axle 11 through mechanical transmission and move right on fixed pipeline 94, fixed pipeline 94 left end promotes two movable plates 88 and upwards and downstream respectively, thereby the left end of fixed pipeline 94 stretches out from board groove 96, start pump 39, the paint in paint chamber 37 is through drawing away pipeline 38 and fixed pipeline 94 blowout to pump 39 work, thereby mend the paint to the gate that polishes, only need start the reversal of second motor 31 during the reset, drive sealed block 12 through mechanical transmission and move right and reset.
