Problems solved by technology

However, the ice-breaking thickness of traditional air-cushion icebreakers is small and the efficiency is not high. The invention patent with the application number CN201610487788.2 discloses a pressure-type air-cushion icebreaker, which relies on the self-weight of the hull to compress the ice surface to achieve ice-breaking, but it is thicker for the polar regions. It is difficult to achieve the ice-breaking effect only by relying on its own weight to compress the ice surface, so there is an urgent need for an air-cushion icebreaker that can not only drive on the ice surface, but also break through thicker ice as needed.

Embodiment 1

[0026] like Figure 1-3 As shown in the figure, the vertical pressurized air-cushion icebreaker assisted by the robotic arm of the present embodiment includes an icebreaker body 1, an inflatable air cushion 2 is arranged around the icebreaker body 1, and a cab 3, The power machine 4 , the control cabinet 5 and the cargo box 12 are respectively provided with a robotic arm 6 on both sides of the front end of the icebreaker body 1 , an ice breaking mechanism is provided at the front end of the robotic arm, and the front and rear ends of the left and right sides of the icebreaker body 1 are respectively provided There are propellers 7 , several through holes are symmetrically arranged in the middle of the left and right sides of the icebreaker body 1 , several lifters 8 are arranged on the through holes, and several pressure sensors 11 are arranged at the bottom of the icebreaker body 1 .

[0027] The number of the propellers 7 is four, which are respectively arranged on the four ...

Embodiment 2

[0036] like Figure 4 As shown in, the difference between this embodiment and Embodiment 1 is:

[0037] A connecting rod 9 is installed at the middle of the rear end of the icebreaker body through a flange, and an ice discharge blade 10 is provided at the end of the connecting rod 9 .

[0038]When this embodiment is in use, when it is necessary to break ice at the edge of the ice layer, firstly driven by the pitch motor 705, the propeller 7 located at the rear of the icebreaker body 1 is lowered, and the propeller 7 located at the front of the icebreaker body 1 is lowered. The front part of the hull is tilted up, and the robotic arm 6 is supported on the ice surface to balance the hull. Under the thrust provided by the propeller 7, the front part of the icebreaker can jump on the ice layer. At this time, the propeller 7 is restored to the horizontal state, and the lifter 8 continuously discharges air to the lower part of the icebreaker, so that the ice layer is separated from...

Embodiment 3

[0042] like Figure 5 , Figure 7 The difference between this embodiment and Embodiment 2 is:

[0043] The ice breaking device is a tooth saw 608. The two ends of the tooth saw rotating shaft of the tooth saw are installed between two connecting plates 610. The rear part of the connecting plate 610 is hinged with the boom 604, A front-end hydraulic cylinder 606 is hinged between the arms 604 , and the saw shaft is connected to an output shaft of a saw motor 607 .

[0044] When this embodiment is in use, when it encounters a high ice dam and it is difficult for the icebreaker to jump on the ice surface, the tooth saw is driven by the tooth saw motor 607 to rotate at a high speed, and the tooth saw 608 can be used to cut the ice dam and break it. Then use the working method of Example 2 to break the ice.

Abstract

The invention discloses a mechanical arm-assisted vertical supercharged air cushion icebreaker. The mechanical arm-assisted vertical supercharged air cushion icebreaker includes an icebreaker body. Aninflatable air cushion is arranged around the icebreaker body. A cab, a power machine, a control cabinet and a cargo carrying box are arranged in the middle of the icebreaker body from front to rear.Mechanical arms are arranged on both sides of the front end of the icebreaker body respectively, ice-breaking mechanisms are arranged at the front ends of the mechanical arms, thrusters are arrangedat the front end and the rear end of the left side and the right side of the icebreaker body respectively, a plurality of through holes are symmetrically formed in the middles of the left side and theright side of the icebreaker body, lifting devices are arranged above the through holes, and a plurality of pressure sensors are arranged at the bottom of the icebreaker body. The mechanical arm-assisted vertical supercharged air cushion icebreaker adopts the form of a hovercraft so that the air cushion icebreaker can travel on an ice surface for cargo transportation and can also perform icebreaking on ice layers with different thicknesses as required. The application range is wide.

Description

Technical field: [0001] The invention relates to a vertical pressurized air cushion icebreaker assisted by a mechanical arm, belonging to the field of icebreaking equipment. Background technique: [0002] In the cold winter, parts of the Bohai Sea in my country and most of the northern rivers will be frozen, affecting ships entering and leaving the port and normal navigation, requiring ice-breaking equipment to open the channel; when the weather turns warm and the ice in the river melts, in order to avoid the area Larger ice blocks impact the dam, and ice-breaking equipment is often used to break the large block of ice. Therefore, icebreaking equipment plays an important role in opening up ship channels and ensuring the safety of currents. In addition, the polar regions are frozen all year round. With the increase of polar activities, the thick ice layer on the sea surface has brought difficulties to polar activities. Therefore, there is an urgent need for a device that can...
