[0021] A screw block 17 is fixed to the front surface of the outer cylinder 13, and the inside of the screw block 17 is threadedly connected to the screw rod 12. The upper surface of the inner part of the outer cylinder 13 is rotatably connected to the rotating cylinder 20. Two bevel gears 25 are symmetrically fixed above the outer surface of the rotating cylinder 20. A spiral blade 21 is provided at the lower surface of the outer surface of the rotating cylinder 20. A slide rod 22 is slidably connected to the lower inside of the rotating cylinder 20. The bottom of the slide rod 22 is fixedly connected to the center of the upper surface of the turntable 19. The inner wall of the inner cylinder 18 is rotatably connected to the transmission gear 23. The rear surface of the inner part of the outer cylinder 13 is rotatably connected to the incomplete gear 26. The rear end of the incomplete gear 26 passes through the rear surface of the outer cylinder 13 and is fixed with a bevel gear 27. The bottom of the bevel gear 27 is meshed with a bevel gear 3 29. The bottom of the bevel gear 3 29 is fixedly connected to a spur gear 30. The bottom of the spur gear 30 is rotatably connected to a bracket 28.

The ice-breaking ring 42 is fixed to the outer side of the ice-breaking cone 41. During use, the hydraulic rod 2 is extended to cause the lifting frame 1 and its internal structure to descend, so that the ice-breaking wheel 15 contacts the ice surface, and the motor 2 16 drives the ice-breaking wheel 15 to rotate. At the same time, the motor 11 drives the screw rod 12 to rotate, so that the two ice-breaking mechanisms 5 move relative to each other, thereby performing horizontal ice-breaking operations at the gate; during movement, the spur gear 30 is rotated by the meshing of the rack 31, and then the incomplete gear 26 is continuously rotated under the transmission of the bevel gear 3 29 and the bevel gear 2 27. During the rotation of the incomplete gear 26, it is intermittently meshed with the upper and lower bevel gears 1 25 for transmission, so that the rotating drum 20 rotates axially back and forth, and the transmission gear 23 is driven to rotate forward and backward through the spiral blade 21, and then the transmission gear 23 is meshed with the tooth groove 24, so that the inner drum 18 drives the turntable 19 and other internal structures to perform repeated lifting and retracting operations. When the two ice-breaking mechanisms 5 are close, the two connecting plates 6 will push the lifting plate 7 and the ice-breaking blade 10 downward, and the cross-shaped ice-breaking blade 10 will contact the ice surface and press down the ice layer between the two ice-breaking mechanisms 5.
[0024] Reference Figure 9A spring 35 is fixed between the slide 33 and the inner wall of the slide groove 32. When the slide 33 is pressed and moves inward relative to each other, the slide 33 will move and compress the spring 35 under the drive of the connecting frame 38. When the compression is lost, the spring 35 will assist the slide 33, the connecting frame 38 and other structures to reset.
[0025] Reference Figure 2 The bottom of the ice-breaking ring 42 and the outer surface of the ice-breaking wheel 15 are both provided with a number of triangular cutting teeth. The four ice-breaking cones 41 form a cone structure, and the ice-breaking blade 10 is a cross-shaped structure. The four ice-breaking mechanisms are used simultaneously to better perform ice-breaking operations.
[0026] Reference Figure 1 The mounting plate 3 is fixedly connected to the top of the external gate frame by bolts, so that the device can be conveniently installed on the inside of the water conservancy gate structure.
[0027] Reference Figure 7 The slide rod 22 is a rectangular rod structure, so that when the drum 20 rotates, the slide rod 22 will drive the turntable 19 to rotate accordingly. The incomplete gear 26 is adapted to the two bevel gears 25. When the incomplete gear 26 rotates, it can be meshed and connected with any one of the bevel gears 25, but can only be meshed and connected with a single bevel gear 25 above or below at the same time.
