[0020] During implementation, the test ship 200 simulates the main structure of the hovercraft, the air supply component 300 can deliver gas to the bottom of the ice layer, thereby forming an air cavity under the ice layer, and the traveling component 400 drives the test ship 200 to press on the ice layer above the air cavity, thereby realizing the air cavity icebreaking process. The cooperation of the test ship 200 and the air supply component 300 can replace the hovercraft, effectively reducing the equipment cost. At the same time, through the setting of the air supply component 300, it is convenient to control the air supply direction, so that the delivered gas can be accurately delivered to the predetermined position, and the formation position of the air cavity can be effectively controlled, which is convenient for studying the relationship between the travel route of the hull and the air cavity on the icebreaking effect.

[0021] The pool 100 in this embodiment is filled with water, and ice plates M can be made on the water surface by ice making equipment.

[0022] The test ship 200 in this embodiment is a common hull structure and has a lower cost than a hovercraft.

[0023] The air supply assembly 300 in this embodiment is installed on the test ship 200. Along the traveling direction of the test ship 200, the air supply assembly 300 has an air supply end extending to the front of the test ship 200 and located at the bottom of the test ship 200.

The other end of the air supply pipe 320 extends to the front of the test ship 200 and is located at the bottom of the test ship 200, and is connected to the air nozzle 330.

[0025] The air pump 310 is a structure for conveying air that can be imagined by those skilled in the art.

[0026] The air supply pipe 320 in this embodiment is a structure connecting the air pump 310 and the air nozzle 330, and is used to transfer the air delivered by the air pump 310 to the air nozzle 330. It should be noted that in order to prevent the air supply pipe 320 from affecting the icebreaking process of the test ship 200, the part of the air supply pipe 320 located above the water surface should not be set in front of the test ship 200, that is, the part of the air supply pipe 320 located above the water surface can be set on both sides or the tail of the test ship 200.

[0027] The air supply pipe 320 in this embodiment is arranged at the stern of the test ship 200, wherein the air supply pipe 320 includes a fixed pipe 321 and a transverse pipe 322, one end of the fixed pipe 321 is connected to the air outlet end of the air pump 310, the other end of the fixed pipe 321 extends along the stern of the test ship 200 and is connected to one end of the transverse pipe 322, the other end of the transverse pipe 322 extends to the front of the test ship 200, and the transverse pipe 322 is located at the bottom of the test ship 200.

It can be understood that the traveling assembly 400 is a structure for driving the test ship 200 to travel, and the embodiment of the present invention does not limit this.

[0038] Compared with the prior art: the test ship 200 simulates the main body structure of the hovercraft, the air supply component 300 can deliver gas to the bottom of the ice layer, thereby forming an air cavity under the ice layer, and the traveling component 400 drives the test ship 200 to press on the ice layer above the air cavity, thereby realizing the air cavity icebreaking process.
