Fast and continuous ice breaking mechanism

Abstract

The invention provides a fast and continuous ice breaking mechanism, which comprises a spiral saw, a saw frame, a pneumatic arm, a support arm and speed reduction gear sets, wherein the spiral saw is arranged on the saw frame; the whole spiral saw is of a row type spiral structure; the row type spiral structure adopts a clockwise direction design; the saw frame is provided with a dismountable structure; the saw frame is of a parallelogram shape; a power supply driving mechanism is arranged on the saw frame, and is connected with the spiral saw driving mechanism; a pneumatic arm and two support arms are arranged on an outer frame of the saw frame; the pneumatic arm and the two support arms form a structure; three force arms extend out from the center point of the structure; a three-force-arm structure forms a triangular stable and firm structure; the two support arms have the same size; the two support arms are arranged in the same horizontal line; the pneumatic arm is arranged above the two support arms; the connecting part of the back end of each of the two support arms and a boat body is provided with the speed reduction gear set; gears of each gear set are mutually connected and engaged and are matched with the corresponding support arms; an air cylinder is arranged in the pneumatic arm; and the design that the whole saw frame is rotatablely arranged at the outer side of a broad side is used, so that the work efficiency of an ice breaking boat is improved.

Description

Technical field: [0001] The present invention and an icebreaking device, in particular, relate to a rapid and continuous icebreaking mechanism, which utilizes the cutting principle of a pneumatic arm belt-row combined spiral saw to increase the icebreaking capability of an icebreaker, and can realize rapid and continuous icebreaking, which is a field where mechanical automation icebreaking operations are required. Background technique: [0002] The current working method of the icebreaker is to crush the ice through the gravity drop formed by the pressurized water tanks at the bow and stern of the ship. When encountering an ice block whose thickness exceeds half a meter, it is necessary to use the impact of the ship to subdue it. One kind of ice breaking is purely using the ship's own gravity or power, and the hull fracturing method and hull impact method have low work efficiency, long ice breaking operation time, slow ice breaking operation speed, and a small ice breaking ar...

Problems solved by technology

There are disadvantages in this patent: 1. It is feasible to saw thin ice with a saw blade, but it is more difficult to saw thick ice or icebergs; 2. The design structure of this patent is not reasonable. The design is relatively rigid, and the saw blade cannot work in a large area, but can only be carried out in a small area. It is very laborious to work on the big ocean, and the effect is not good.

The patented design has disadvantages: 1. The bracket is fixed on the icebreaker, which limits the ice-breaking flexibility of the toothed wheel, and cannot be deployed well in a large area. At the same time, it will not be possible to carry out work in shallow lakes with aquatic plants; 2. The bracket is on the icebreaker. Below the bottom of the ice layer, when the ship is moving forward, the bracket lifts up the ice layer, and the ice breaking work is performed by the bracket. If it works for a long time, the bracket will be seriously damaged.
