[0031] The specific implementation of the present application is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1 As shown, a polar icebreaking vehicle is provided in an embodiment of the present application, and the vehicle includes: a main body and a water jet cutting device 500.

[0033] The water jet cutting device 500 is arranged on the main body, and the water jet cutting device 500 includes a high-pressure pump 510 and a cutting nozzle 520. The input end of the high-pressure pump 510 is used to suck water flow from the outside of the main body, and the output end of the high-pressure pump 510 is connected to the cutting nozzle 520 through a first conduit. The high-pressure pump 510 is used to provide high-pressure power for the water flow, and the cutting nozzle 520 is used to spray a water jet to cut the ice layer on the water surface.

[0034] In this embodiment, water flow is sucked from the water area where the aircraft is traveling by the high-pressure pump 510 and pressurized. The pressurized water flow passes through the first conduit to the cutting nozzle 520 and is ejected through the cutting nozzle 520 to form a water jet to cut the ice layer on the water surface. In this way, water flow is sucked from the water area where the aircraft is traveling and used to cut the ice layer. There is enough water flow for cutting, and the aircraft can work for a long time to achieve continuous ice breaking.

[0035] like Figure 5As shown, as a preferred embodiment of the present application, the main body includes a shell 110, the shell 110 has a first cavity, the water jet cutting device 500 also includes a base 530 arranged in the first cavity, the high-pressure pump 510 is fixedly arranged on the base 530, the cutting nozzle 520 is connected to the base 530 through a first telescopic component 540, the first telescopic component 540 is used to drive the cutting nozzle 520 to extend or retract the shell 110, and the shell 110 is provided with an avoidance hole 111 for the cutting nozzle 520 to extend.

[0036] In this embodiment, the cutting nozzle 520 is driven to extend or retract into the shell 110 through the first telescopic component 540. The cutting nozzle 520 is extended when cutting is required, and is retracted during navigation or when cutting is not required, thereby reducing navigation resistance.

In some embodiments of the present application, a second sealing member is also provided on the cutting nozzle 520, and when the cutting nozzle 520 extends out of the avoidance hole 111, the second sealing member blocks the avoidance hole 111.

The water pressure sensor is used to monitor the water pressure at the location of the vehicle. When the water pressure reaches a preset threshold, the controller controls the second telescopic component 550 to contract to open the avoidance hole 111, and controls the transverse drive device and the first telescopic component 540 to drive the cutting nozzle 520 and the infrared sensor 590 to extend out of the avoidance hole 111.

[0040] In this embodiment, the preset threshold value may be a water pressure value at 2 meters underwater, or a water pressure value at other depths, as long as the infrared sensor 590 can detect the ice layer on the water surface at the depth. The water pressure sensor feeds back water pressure information to control the aircraft to float to a predetermined position on the water surface, and then the infrared sensor 590 and the cutting nozzle 520 are extended out of the housing 110, and the infrared sensor 590 takes over the work of the water pressure sensor to detect the distance between the cutting nozzle 520 and the ice layer on the water surface, so as to control the aircraft to continue to float until the cutting nozzle 520 reaches a suitable position to cut the ice layer. In this way, through the cooperation of the water pressure sensor and the infrared sensor 590, the aircraft can be accurately controlled to float.

[0041] In some embodiments of the present application, the water jet cutting device further includes a heating tube for heating the water flow, the input end of the high-pressure pump is connected to one end of the heating tube, and the other end of the heating tube is used to suck the water flow from the outside of the main body.
