[0048] Referring to Figures 1 to 7 The deicing method for deicing the gate slot of the water conservancy facility according to an embodiment of the present application uses the above-mentioned deicing device for deicing. Specifically, the deicing method comprises:

[0049] S710, hoisting the deicing device above the ice surface.

[0050] Specifically, after the deicing device is assembled and overhauled, the entire deicing device can be suspended above the ice surface at the ice freezing position of the gate slot by using hoisting equipment such as an electric hoist.

[0051] S720, starting the air compression device 4 and slowly lowering the deicing device to the ice surface.

[0052] Specifically, before the ice crushing assembly 1 starts to crush ice, the air compression device 4 is started first, and the entire deicing device is slowly lowered, so that the pneumatic motor 12 reaches a certain rotating speed, to facilitate the planing of the ice surface by the cutter head 144.

[0053] S730, continuously planing the ice surface by the ice crushing assembly 1, and the crushed ice generated by the planing enters the ice discharging cylinder 2 through the ice crushing assembly 1, and is discharged by the ice discharging cylinder 2.

[0054] Specifically, the ice shaving assembly 1 shaves the ice surface and the shaved ice enters the ice discharge cylinder 2 through the straight cylinder 111 as the cutter head 143 rotates, and the shaved ice is finally discharged from the ice discharge cylinder 2 to the outside of the gate slot of the water conservancy facility.

[0055] Further, when the ice removal device is operated for a period of time, the opening degree of the regulating valve 31 of the composite multi-way joint 3 connected with the ice discharge cylinder 2 is increased, so as to increase the air flow of the compressed gas flowing into the ice discharge cylinder 2 from the air compression device 4.

[0057] Further, when the ice surface in the entire gate slot is processed and completed by the ice removal device, the entire ice removal device can be hoisted and recovered by hoisting equipment such as an electric hoist. After the recovery is completed, the idle gate valve of the composite multi-way joint 3 is opened. The construction personnel perform gas impact cleaning on the outer surface of the entire ice removal device and the cavity of the guide cylinder 11 through the steel wire hose connected with the composite multi-way joint.

[0058] In summary, the ice discharge cylinder is connected with a plurality of ice shaving assemblies in the present application, and each ice shaving assembly shaves the ice surface and discharges the shaved ice generated by the ice shaving assembly from the ice discharge port of the ice discharge cylinder under the driving of the air compression device, so as to solve the problem of ice formation in the gate slot of the water conservancy facility in high-cold and high-altitude areas in winter. Further, the sewage suction pump is arranged at the ice discharge port of the ice discharge cylinder in the present application, and when the shaved ice in the transfer conduit is not transferred smoothly, the construction personnel can increase the power of the sewage suction pump to accelerate the discharge rate of the shaved ice in the transfer conduit. Further, the helical blades are arranged along the shaft body of the rotating shaft in the present application, so as to accelerate the discharge rate of the shaved ice.
