The working principle of the invention is as follows: and (3) ice crack cleaning operation: before use, the air bottle mechanism 2 is filled with compressed air. The air supply valve 2-1 is closed, and the air outlet valve 2-3 is opened. The compressed air reaches the air outlet valve 2-3 through the air pipe, reaches the nozzle 5 through the air outlet valve 2-3, is sprayed out through the nozzle 5, and blows out ice chips and sundries in the ice crack. And sundries and ice scraps are left in the protective wall 4-5 under the action of the protective wall 4-5. And closing the air outlet valve 2-3.
And (3) water replenishing at the ice gaps: a certain amount of water is injected into the water tank mechanism 1, the air compensating valve 2-1 is opened, and compressed air is injected into the water tank mechanism 1, so that the internal pressure of the water tank mechanism 1 is increased. And closing the air compensating valve 2-1. When the water valve 1-5 is opened, the water in the water tank mechanism 1 will follow the water pipe under the action of the air above to reach the water valve 1-5 and then reach the nozzle 5 through the three-way pipe. The nozzle sprays water into the ice crack; after injecting proper amount of water, the water valve 1-5 is closed. And slightly opening the air outlet valve 2-3 to blow out the water in the water pipe so as to prevent the water in the pipe from condensing and cracking the water pipe.
Refrigeration and condensation: the nitrogen gas valve 3-3 is opened, and liquid nitrogen gas flows out from the nitrogen gas cylinder mechanism 3 and flows into the nitrogen sprayer 4 through the nitrogen gas pipe. The nitrogen gas fills the buffer ring 4-3 of the nitrogen sprayer 4 and flows into the ice crack through the nitrogen outlet 4-4. The liquid nitrogen quickly refrigerates and condenses the water in the ice crack;
polishing an ice seam: the sanding plate 11 is pushed over the ice crevice. The motor mechanism 7 is switched into the circuit. And starting the motor. The motor rotates to drive the belt pulley 7-1 to rotate, the belt pulley 7-1 is connected with the rest belt pulley 9-2 through the belt 7-2, and the belt pulley 9-2 rotates. The belt wheel 9-2 is fixed on the upper part of the rotating shaft mechanism 9, and the rotating shaft mechanism 9 rotates. The rotating shaft mechanism 9 drives the lower grinding plate 11 to rotate;
when the cam mechanism 6 is rotated, the lower part of the cam mechanism 6 is contacted with the rotating shaft mechanism 9, the cam mechanism 6 presses the rotating shaft mechanism 9 downwards, the upper part of the rotating shaft mechanism 9 is fixed on the bearing 8-3, and the bearing 8-3 is fixed on the sliding support rod 8 through the bearing cover 8-2. The rotating shaft moves downwards to drive the sliding support rod 8 to slide downwards, and the sliding block 8-1 moves downwards to press the lower spring.
