Problems solved by technology

However, the icebreaker adopting the continuous icebreaking method breaks ice slowly, and the icebreaking efficiency is low, and it can only be used in sea areas with small ice thickness and thin thickness, and has high requirements on the strength of the ship itself; Low energy consumption, high energy consumption, the biggest problem is that the hull is easily stuck by ice, and because the two types of icebreakers depend on the hull and speed of the icebreaker, the hull structure, propulsion device and ancillary facilities of the two types of icebreakers are equally important. It has high requirements and high cost. In addition, due to the adjustment of ballast water tanks in shallow sea areas, neither of the two types of icebreakers can break ice in shallow sea areas.

Embodiment 1

[0031] This embodiment proposes an icebreaker, the stern of the hull is provided with a propeller traveler 1, the bow of the hull is provided with a fixed support plate 3, the bottom surface of the fixed support plate 3 is fixedly connected with a support rib 16, and the middle part of the front end of the fixed support plate 3 is provided with a Groove; fixed support plate 3 is provided with motor base 17, two raised bases 7 and four bearing support bases 15; motor base 17 is provided with two main motors 4, and the motor is connected with pulley I19, pulley I19 Connect the pulley II14 by the belt 5, the pulley II14 is fixedly connected on the rotating shaft 20, the rotating shaft 20 is provided with a saw blade 6, and the saw blade 6 is positioned in the groove at the middle part of the front end of the fixed support plate 3; Bearing 23 is arranged, and bearing 23 is fixedly connected with rotating shaft 20; Rotating shaft 20 is also provided with two cams 13, is provided wit...

Embodiment 2

[0038] This embodiment proposes an icebreaker, including the entire structure of the icebreaker described in Embodiment 1. The difference from Embodiment 1 is that two spring supports 2 are also provided on the fixed support plate 3, and the spring supports 2 are located on the lifting lugs. The front end of I8 is fixedly connected with spring 18 on the spring support 2, and the other end of spring 18 is fixedly connected with spacer 33, and spacer 33 contacts with hammer handle 10 and is connected, and the both sides of spring 18 are provided with limit baffle 11, position-limiting The baffle 11 is fixedly connected with the spring support 2 , and the height of the limit baffle 11 is higher than that of the spring 18 .

Embodiment 3

[0040] Such as Figure 1~5 As shown, this embodiment proposes an icebreaker, including all the structures of Embodiment 1 and Embodiment 2. The difference from Embodiment 1 and Embodiment 2 is that in an optional implementation of this embodiment, the hull also includes a transmission area 32 , the transmission area 32 is provided with an auxiliary motor 31; the auxiliary motor 31 is connected to the crankshaft 30, the other end of the crankshaft 30 is connected to the bearing housing 29, and the crankshaft 30 is also connected to nineteen connecting rods; the other end of each connecting rod is connected to a small icebreaker 21. The small ice-breaking hammer 21 is set in the slot 24 on the side of the hull; the slot 24 is also provided with a bearing 23 and a pin shaft II22, and the other end of the small ice-breaking hammer 21 is fixed on the slot 24 through the bearing 23 and the pin shaft II22 Inside; connecting rod comprises rod I27 and rod II25, and rod I27 and rod II25...

Abstract

The invention relates to the technical field of ships, in particular to an icebreaker and an icebreaking method. The icebreaker is characterized in that a fixed supporting plate is arranged at the head of the icebreaker, a supporting rib plate is fixedly connected to the bottom face of the fixed supporting plate, and a groove is formed in the middle of the front end of the fixed supporting plate; a motor seat, two heightened bases and four bearing supporting seats are arranged on the fixed supporting plate; two main motors are arranged on the motor base, the motors are connected with rotating shafts through belts, and saw blades are arranged on the rotating shafts. A bearing is arranged on the bearing supporting seat and is fixedly connected with the rotating shaft; two cams are further arranged on the rotating shaft, a lifting lug I is arranged on the heightened base, the lifting lug I is fixedly connected with a pin shaft I, the pin shaft I is fixedly connected with a hammer handle, the hammer handle is fixedly connected with a hammer body, and the hammer handle is located above the cams and is in contact connection with the cams. The ice breaker is simple in structure, reasonable in design and capable of breaking the ice surface with large thickness and effectively improving the ice breaking efficiency.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an icebreaker and an icebreaking method thereof. Background technique [0002] An icebreaker is a service ship used to break the ice on the water surface, open up waterways, ensure ships enter and leave ice-covered ports, anchorages, or guide ships sailing in ice areas. There are mainly two kinds of existing ice-breaking methods: a continuous ice-breaking method and an impact ice-breaking method. Based on these two ice-breaking methods, there are mainly two types of existing ice-breaking ships: the ice-breaking ship adopting the continuous ice-breaking method and the ice-breaking ship adopting the ram-type ice-breaking method. When the thickness of the ice layer does not exceed 1.5 meters, the icebreaker adopts the continuous icebreaking method to break the ice. During the icebreaking process, the icebreaker moves steadily forward through the ice layer at a speed of 3 to 5 knots p...
