The invention also provides an operation method of the winter anti-freezing river channel water-blocking gate for the hydraulic engineering, and the winter anti-freezing river channel water-blocking gate for the hydraulic engineering is implemented by the following steps:

step 1, when a gate needs to be opened and closed, starting a driving motor 45, starting the driving motor 45 to drive a driving conical pulley to rotate so as to drive a driven conical pulley to rotate, driving a driving screw rod 48 to rotate by the rotation of the driven conical pulley and further driving a rotating toothed belt 43 to rotate, driving a driven gear 46 to rotate by the rotation of the rotating toothed belt 43, further driving a driven screw rod 41 to rotate, driving a sealing gate plate 6 to slide on the inner side of a fixed side wall 2 by the rotation of the driven screw rod 41 and the driving screw rod 48, moving the sealing gate plate 6 upwards, and opening the gate;

step 2, when the contact surface between the fixed side wall 2 and the sliding side plate 5 needs to be subjected to anti-freezing treatment, the electric heating block 33 is started to generate heat, the electric heating block 33 generates heat to heat the air in the inner cavity of the installation side box 31, the temperature of the air in the inner cavity of the installation side box 31 is increased, the temperature of the outer wall of the installation side box 31 is increased to melt the ice crystals, and the hot air in the installation side box 31 flows to the inner side of the fixed side wall 2 through the ventilation bevel 34 to melt the ice crystals in the inner side of the fixed side wall 2;

step 3, river water floats to drive the floating mounting plate 52 to float, the floating mounting plate 52 drives the lifting sliding wheel 53 to slide on the inner side of the fixed side groove 51, and the floating mounting plate 52 drives the anti-freezing mechanism 7 to move to a specified position;

step 4, starting inflation by a high-pressure air pump 70, electrifying a heating block to heat air in the inner cavity of the heating box 79, leading hot air to the inner cavity of an air inlet pipeline 78 by the high-pressure air pump 70, leading the hot air into the inner cavity of an air bubble generating pipe 72 through the air inlet pipeline 78, further leading the hot air into river water, leading the hot air to generate bubbles under the pressure action of the river water, floating the bubbles to drive the river water to move, raising the temperature of the local river water, leading the hot air into a closed space formed by the ventilation installation box 71 and an air pipe supporting plate 77, and pushing the lifting vibration block 75 to move upwards;

step 5, when the high-pressure air pump 70 stops working, the lifting vibration block 75 moves downward under the action of its own gravity, the lifting vibration block 75 squeezes air when moving downward, the air flows to the inner cavity of the air inlet pipeline 78 through the pressurizing air pipe 73 and then enters the inner cavity of the air bubble generating pipe 72 to generate air bubbles, and the high-pressure air pump 70 intermittently operates to drive the lifting vibration block 75 to move up and down.
