[0020] like Figure 1 As shown, the present invention provides an air cavity icebreaking test device, which includes a water pool 100, a test ship 200, an air supply component 300 and a traveling component 400; the test ship 200 is arranged on the water pool 100 and can travel on the water surface; the air supply component 300 is installed on the test ship 200, and along the traveling direction of the test ship 200, the air supply component 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 traveling component 400 is installed on the water pool 100 and connected to the test ship 200, and is used to drive the test ship 200 to move.

[0021] During implementation, the test ship 200 simulates the main structure of the hovercraft, and the air supply component 300 can deliver gas to the bottom of the ice layer, thereby forming an air cavity under the ice layer. 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 influence of the relationship between the travel route of the hull and the air cavity on the icebreaking effect.

[0022] In this embodiment, the pool 100 is filled with water, and ice plates M can be made on the water surface by ice making equipment.

[0023] The test vessel 200 in this embodiment has a common hull structure and is lower in cost than a hovercraft.

[0024] The air supply assembly 300 in this embodiment is installed on the test vessel 200. Along the travel direction of the test vessel 200, the air supply assembly 300 has an air supply end extending to the front of the test vessel 200 and located at the bottom of the test vessel 200. The air supply assembly 300 can deliver air to the water below the ice sheet M. The air rises to the bottom of the ice sheet M and forms an air cavity between the ice sheet M and the water surface.

[0025] like Figure 2As shown, in one embodiment, the air supply assembly 300 includes an air pump 310, an air supply pipe 320 and an air nozzle 330. The air pump 310 is installed on the test ship 200. The air outlet end of the air pump 310 is connected to one end of the air supply pipe 320. 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.

[0026] The air pump 310 is a structure for conveying air that can be imagined by those skilled in the art.

[0027] 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 to prevent the air supply pipe 320 from affecting the icebreaking process of the test ship 200, the portion of the air supply pipe 320 located above the water surface should not be located in front of the test ship 200. In other words, the portion of the air supply pipe 320 located above the water surface can be located on both sides or at the rear of the test ship 200.

[0028] The air supply pipe 320 in this embodiment is arranged at the tail of the test ship 200, wherein the air supply pipe 320 includes a fixed pipe 321 and a cross pipe 322.

It is understood that the height adjustment member 340 can be implemented using a cylinder, an electric push rod, or other structures.

[0030] To allow for vertical displacement of the connection between the fixed tube 321 and the transverse tube 322, in one embodiment, the air supply tube 320 further includes a bellows 323. The fixed tube 321 communicates with the transverse tube 322 via the bellows 323. The deformation of the bellows 323 allows the transverse tube 322 to move vertically relative to the fixed tube 321.

[0031] To test the ice-breaking effect at different air supply angles, in one embodiment, the air supply assembly 300 further includes a hose and an angle adjustment member. The air supply pipe 320 is connected to the air nozzle 330 via the hose. The angle adjustment member is mounted on the air supply pipe 320, with its output end connected to the air nozzle 330, for driving the air nozzle 330 to rotate. The angle adjustment member can use a structure such as a cylinder or an electric push rod to drive the air nozzle 330.

[0032] In another embodiment, the air supply pipe 320 and the air nozzle 330 may be connected by a ball joint.

The two sides of the trolley 410 are slidingly connected to the two guide rails 420, and the bottom of the trolley 410 is connected to the test ship 200.

[0036] During the icebreaking process, the test ship 200 vibrates. Therefore, the traveling assembly 400 in this embodiment further includes a shock absorber 430 , and the traveling vehicle 410 is connected to the test ship 200 via the shock absorber 430 .

[0037] Among them, the shock absorber 430 includes multiple connecting rods and multiple shock-absorbing springs. The top ends of the multiple connecting rods are all passed through the traveling crane 410 and are all slidably connected to the traveling crane 410 in the vertical direction. The bottom ends of the multiple connecting rods are fixedly connected to the test ship 200. The multiple connecting rods are respectively passed through the multiple shock-absorbing springs. The top ends of the multiple shock-absorbing springs are all fixedly connected to the traveling crane 410, and the bottom ends of the multiple shock-absorbing springs are fixedly connected to the test ship 200.

It is understood that the traveling assembly 400 is a structure for driving the test vessel 200 to travel, and this embodiment of the present invention is not limited thereto.

[0039] Compared with the existing technology: the test ship 200 simulates the main structure of the hovercraft, the air supply component 300 can transport 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.
