The invention relates to the field of mechanical technology, and provides an embedded bow ice-breaking device based on the principle of resonance, which is mainly composed of three parts: a resonance wheel, a power system and a position scheduling system. The resonance wheel is mainly composed of a hub, a ring gear and a shaft, which is used to drive the bow structure to vibrate at a specific frequency after the icebreaker climbs onto the ice layer; The device structure is used to provide power to the resonance wheel; the position adjustment system is composed of a pair of synchronous hydraulic cylinders, buckles and leaf springs, which are used to adjust the position of the resonance wheel and buffer the impact load of the ice layer on the resonance wheel. The remarkable advantage of the present invention is that the device can effectively improve the ice-breaking capacity without significantly increasing the displacement, effectively avoid being jammed by crushed ice, and can ensure the strength and wear resistance of the gear teeth, improving the mobility of the structure.

The invention discloses an efficient starter. The efficient starter comprises an electromagnetic switch. The electromagnetic switch comprises a switch cover assembly and a switch body which are connected in a sealed mode; a movable contact assembly is arranged inside the switch body; a static contact assembly matched with the movable contact assembly is arranged inside the switch cover assembly; the movable contact assembly comprises an arch-shaped movable contact; the static contact assembly comprises two static contacts matched with the movable contact; and the end faces, close to the movable contact, of the two static contacts are in an annular rib shape. Compared with the prior art, the movable contact in the movable contact assembly is designed to be in an arch shape, the end faces, close to the movable contact, of the two static contacts are in an annular rib shape, and accordingly the overlapping area of two corresponding faces between the movable contact and the static contactsis reduced, when the electromagnetic switch is connected, the pressure intensity between the movable contact and the static contacts is increased, and accordingly the ice breaking capacity is improved and the purpose of improving the communication capacity of the electromagnetic switch is achieved.

An unmanned ice-breaking submersible
ActiveCN107856816BImprove ice breaking abilityStrong ice breaking abilityIce breakersUnderwater vesselsMarine engineeringHigh pressure
The invention provides an unmanned under-ice ice-breaking submersible. The tail part of a hull is a hull ballast tail provided with ballast; an ice-breaking drill is arranged at the front end of a bowof the hull; a watertight transverse bulkhead is arranged at the middle in the middle part of the hull; the watertight transverse bulkhead divides the space in the middle part of the hull into a first ballast tank and a second ballast tank; the top ends of the first ballast tank and the second ballast tank are respectively provided with high-pressure air cylinders and high-pressure air pipes; oneend of each high-pressure air pipe communicates with the corresponding high-pressure air cylinder and the other end of each high-pressure air pipe is a closed end; the first ballast tank and the second ballast tank are both provided with seacocks and air vent valves at the bottom ends; each high-pressure air pipe is also provided with a corresponding high-pressure air valve switch; the two high-pressure air cylinders communicate with each other; and the high-pressure air cylinder in the second ballast tank also communicates with an external umbilical cable. The unmanned under-ice ice-breakingsubmersible is simple in structure. When a polar ship encounters an ice area requiring higher ice-breaking capacity than the ice-breaking capacity of the ship, the polar ship can break the ice and navigate by virtue of the unmanned under-ice ice-breaking submersible, so that the ice-breaking capability of the ship under extreme conditions at the ice area can be greatly improved.
