and (3) equilibrium state:
the first state: when the ice breaker is vertically placed in water, the acting force of water flow on the ice breaker and the centroid point of the ice breaker are horizontally collinear and offset, so that a vertical rotating moment cannot be generated, and the ice breaker reaches balance in a vertical state under the action of the gravity of the pump body structure and the design action of the main body cavity and the annular wing-shaped cavity structure;
and a second state: when the upper end of the ice breaker is placed in water in a left-inclined state, namely the right side of the annular wing-shaped cavity body is higher than the left side structure, the water flow generates an upward thrust on the left side of the annular wing-shaped cavity body, and because the direction of the upward thrust is not collinear with the centroid point and has a certain angle with the centroid line, the water flow has a clockwise rotation moment on the left side of the annular wing-shaped cavity body; meanwhile, the pump body structure has large gravity and a certain angle between the gravity and the centroid point, the pump body structure can also generate a clockwise rotation moment, and at the moment, the ice breaker can rotate clockwise to adjust the position until the ice breaker is balanced in a vertical state; if the ice breaker is placed in water, the right side of the annular wing-shaped cavity body is lower than the left side structure, and the ice breaker rotates anticlockwise to adjust the position until the ice breaker is balanced in a vertical state according to the principle;
and a third state: when the ice breaker is placed in water in a horizontal state, the action force of water flow on the annular wing-shaped cavity body on the left side of the ice breaker is collinear with the centroid point, so that the rotating moment at the position is zero; due to the fact that the gravity of the pump body structure is large, under the action of the gravity generated at the position of the pump body structure, a certain angle is formed between the gravity and the centroid point, a clockwise rotating moment is generated, and therefore the ice breaker can rotate clockwise, pass through the state II and finally reach the state I, and further reach balance in a vertical state;
water pumping balance: when the ice breaker starts to work normally, the motor drives the blades and the wheel hub to rotate, negative pressure is generated in the pump body shell, water flow near the pump body structure enters the pump body shell through a filter screen on the filter device frame under the action of pressure intensity, and the water passing section of the cavity of the pump body is larger than that of the annular water diversion pipe; the water passing section of the annular water diversion pipe is larger than that of the water spraying pipe, so that the water flowing through the water spraying pipe is increased in speed, and the water cannot freeze;
