Abstract
An automatic propeller entanglement cutting device comprises a cutting tool, and is characterized in that the cutting tool is arranged on the outer wall of the stern tube of a ship, and spans across a groove between the stern tube and the propeller drum. The cutting tool has a blade edge facing the end face and the outer lateral surface of the impeller. The automatic propeller entanglement cutting device can automatically cut the entanglement on the propeller along with the rotation of the propeller, and has the advantages of simple structure, complete cutting and high efficiency. The automatic propeller entanglement cutting device is applicable to various ships to avoid the faults caused by the entanglement of the propeller.
Description
Technical field
The present invention relates to the Equipment of Vessel auxiliary device, relate in particular to a kind of auto cutting device for twister of propeller.
Technical background
When boats and ships ride the sea, the screw propeller of boats and ships is usually twined by the floating debris in the seawater (the various cables that fishing net, hawser or underwater engineering are left over), have influence on the normal operation of screw propeller, cause boats and ships to run out of steam sometimes, cause a serious accident, so, need a kind of device that the various materials that are wrapped on the screw propeller are cut voluntarily.
The automatic cutting technique of screw propeller twister has developed for many years abroad, mainly contains three kinds of forms: efficient rope diced system (quicKutter
TMRope cutter system), disc type cutter (disc cutters) and scissor cutter (scissor cutters).Preceding a kind of efficient rope diced system design is comparatively reasonable, can produce additional resistance and water noise hardly, on large tonnage boats and ships, use, but, efficient rope diced system only is provided with blade at the end face of cutter, the side is not provided with blade, and therefore, this system is not good to the cutting effect that large-area fishing net twines; Second and the cutting tool of the third form mainly be arranged on the tailing axle, its cutter blade is vertical with tailing axle, produces bigger resistance and noise, mainly is used in above the canoe.
Above-mentioned cutting method ubiquity cutting is not thorough, the problem that effect is not so good.
Summary of the invention
The objective of the invention is in order to solve the cutting that the above-mentioned background technology exists not thoroughly, the problem that effect is not so good proposes a kind of simple in structurely, can thoroughly excise the auto cutting device for twister of propeller that is wrapped in various materials on the screw propeller automatically.
For achieving the above object, the present invention adopts following technical scheme: a kind of auto cutting device for twister of propeller, comprise cutting tool, it is characterized in that described cutting tool be installed on the outer wall of boats and ships stern pipe or beauty's frame and stride across boats and ships stern pipe or beauty's frame and screw propeller oar drum between groove, described cutting tool is provided with blade towards the end face and the lateral surface of screw propeller.
Described cutting tool is installed on the outer wall of boats and ships stern pipe or beauty's frame along the direction with boats and ships stern pipe or beauty's frame axially parallel.
Described cutting tool is installed on the outer wall of boats and ships stern pipe or beauty's frame along the direction with boats and ships stern pipe or beauty's frame axioversion.
The described cutting tool that is installed on boats and ships stern pipe or the beauty's frame outer wall is evenly arranged along boats and ships stern pipe or beauty's frame circumferencial direction.
The described cutter that are installed on the boats and ships stern pipe outer wall have two, and they are installed in the both sides of symmetry on the boats and ships stern pipe outer wall respectively.
Described cutting tool is the prismatic bar, and the blade of its cutter is arranged on the outer corner angle.
Described cutting tool is provided with blade towards the corner angle of the end face of screw propeller.
Described cutting tool is made up of blade and guide rod, and described blade is embedded in the knife bar, or is welded on the knife bar, or is fastened on the knife bar by screw.
Principle of work of the present invention is as follows: when screw propeller is twined by hawser, hawser rotates around the stern pipe under propeller-driven, progressively embed in the groove between stern pipe and the screw propeller oar drum, under the combined action of the groove between screw propeller and stern pipe and the screw propeller oar drum, hawser is pressed on the cutter, at this moment, the blade of cutter cuts hawser, ruptures until hawser.When large-area fishing net was wrapped on propeller hub and the tailing axle, the side edge of cutter cut fishing net, until fracture.
The present invention is owing to all be provided with blade in the end face and the side of cutter, therefore, utilize the end face blade to be used to cut thicker hawser, utilize the side blade can also cut the bigger twisters such as fishing net of area, particularly adopt cutting tool to stride across feature on the outer wall that groove between boats and ships stern pipe and the screw propeller oar drum is installed in boats and ships stern pipe, make it can increase substantially cutting efficiency, thoroughly excision is wrapped in various materials on the screw propeller, and has the long life-span.
Auto cutting device for twister of propeller of the present invention utilizes the energy of rotation of screw propeller automatically twister to be cut, and it is simple in structure, and cutting thoroughly, efficient is high, can be applicable to various boats and ships, prevents to be wound and the fault that causes by screw propeller.
