Description
Technical field
Marine equipment technical field is the utility model is related to, more specifically, it relates to a kind of propeller for vessels self-shield
Device.
Background technology
In general, the engine of ship is arranged on afterbody, engine is connected by transmission shaft with propeller, i.e. ship
Propeller is typically the exposed bottom after hull, and easily there are following security risk in the process of moving for this ship：When in river
There are weeds or fishing net when debris, be easily wrapped on propeller, aggravate engine load, or even propeller is not rotated.
Therefore, the propeller of spot ship needs installed protection device, so that the debris such as weeds or fishing net is not easy to be wrapped on propeller.
Utility model content
The purpose of this utility model is to provide a kind of propeller for vessels self-protecting device, so that the debris such as weeds or fishing net is not
Easily it is wrapped on propeller.
To achieve the above object, realized by following technological means：A kind of propeller for vessels self-protecting device, including it is spiral
Paddle, propeller include blade and transmission shaft, and the one end of transmission shaft away from blade is provided with some groups of cutting blades, per adjacent two
The blade direction of group blade is opposite.
Through the above technical solutions, cutting blade is arranged on the one end of transmission shaft away from blade, that is, it is arranged on foot side
To front end, then in the process of moving, contact weeds or fishing net first is exactly cutting blade to ship, and cutting blade can be by weeds
Or fishing net is cut off, chopping, in addition cutting blade is installed on transmission shaft, can be rotated by the band cutting blade of transmission shaft,
Can the debris such as comprehensive cutting water plant or fishing net, cutting blade is provided with multigroup, is in order to by cuttings such as water plant or fishing nets
More completely, the blade direction of two adjacent groups blade then touches spiral shell on the contrary, also for that can cut water plant from different perspectives
Revolve paddle blade is exactly weeds chopped or fishing net, blade would not be wound, so as to play protective effect to propeller.
Further it is optimized for：Cutting blade is provided with two groups.
Through the above technical solutions, cutting blade is arranged on the front end of transmission shaft, to cut the debris such as water plant or fishing net,
The group number of cutting blade is set The more the better in theory, so can be by the complete of the cuttings such as water plant, but blade is set
The load of transmission shaft can excessively be increased, in order to guarantee, by the complete of water plant cutting, at least to need the opposite cutting of two groups of blades
Blade, in order not to influence the working condition of transmission shaft, so cutting blade is arranged to two groups is advisable.
Further it is optimized for：The blade of the blade and transmission shaft radial direction are in 15~30 ° of angles.
Through the above technical solutions, when cutting blade cuts water plant, water plant is moved towards transmission shaft axial direction,
Also it is subject to the horizontal component itself pullled when mobile, so water plant and transmission shaft radial direction are at an angle, thus in order to more
Good cuts to water plant, should be by the blade of blade and transmission shaft radial direction at an angle, the radial load being subject to due to water plant
It is not very big, so blade and the angle of transmission shaft radial direction should not also set excessive, being arranged to 15~30 ° is advisable.
Further it is optimized for：The length of the blade is bigger 10~15cm than the length of blade.
Through the above technical solutions, the setting of cutting blade is to touch propeller paddle in the debris such as water plant or fishing net
Shredded before piece, blade is arranged on the front end of blade, can stop the debris such as water plant, so in order into contact with blade
Water plant is all shredded as far as possible, and the length of blade should be longer than the length of blade, it is contemplated that the processing of blade and the design of hull,
Blade is also unsuitable long, so the big 10~15cm of ratio blade length that the length of blade is set is advisable.
Further it is optimized for：The spacing of two adjacent groups blade is 20~30cm.
Through the above technical solutions, two adjacent groups knife-blades be oppositely arranged be in order to cut water plant from different perspectives,
Water plant is blended using the swirling force formed between two groups of opposite blades at the same time, what the spacing of two adjacent groups blade cannot be set
It is too big, the generation of swirling force is otherwise influenced, influences blending for water plant, what in addition can not be set is too small, too small two adjacent groups knife
Piece suffers too near, the water plant limited amount touched, influences to cut water plant, thus the spacing of two adjacent groups blade be arranged to 20~
30cm is advisable.
Further it is optimized for：Each blade is provided with thread segment with respect to one end of transmission shaft, and transmission shaft is opposite with thread segment
The position answered is recessed the thread groove screwed in for thread segment.
Through the above technical solutions, blade is screwed in by thread segment in the thread groove of transmission shaft, the spiral shell with transmission shaft is realized
Line connects, and such staff as needed at any time can get off blade removal maintenance or replacement, contribute to propeller from
The use of protective device.
Further it is optimized for：A water conservancy diversion filter screen for carrying filter hole is provided between blade and cutting blade.
Through the above technical solutions, being provided with filter hole on filter screen, current can be guided to pass through and water plant or fishing net etc.
Debris cannot pass through, and water plant or fishing net can only be from filtering network edges by the way that such filter screen is then by water that is chopping or not shredding
The debris such as grass are all kept off outside propeller blade so that blade does not reach the debris such as water plant or fishing net, would not be by them
Winding, protects propeller blade so that propeller works are smooth.
Further it is optimized for, the diameter of the water conservancy diversion filter screen is bigger 10~15cm than the diameter of blade.
Through the above technical solutions, the setting of water conservancy diversion filter screen is in order to by chopping or the water plant do not shredded or fishing net etc.
Debris is kept off outside propeller blade, so the diameter for the ratio blade that the diameter of filter screen should be set is big, so can just be played
The effect blocked, but the diameter of filter screen can not set too big, too big processing trouble, while also add to transmission shaft negative
Lotus, so the big 10~15cm of diameter for the ratio blade that the diameter of water conservancy diversion filter screen is set is advisable.
Further it is optimized for：The water conservancy diversion filter screen is made of polytetrafluoroethylene material.
Through the above technical solutions, polytetrafluoroethylene material quality is slim and graceful, chemical resistance is good, good weatherability, intensity
Height, water conservancy diversion filter screen is once stamped to form with polytetrafluoroethylene material, and manufacture craft is simple, and obtained filter screen chemically-resistant is rotten
Corrosion is good, and intensity is high, suitably works long hours in water.
The utility model compared with prior art the advantages of be：Cutting blade is installed on transmission shaft, cutting blade can
With by weeds or fishing net cut-out, chopping, cutting blade be provided with it is multigroup, can by the cuttings such as water plant or fishing net more completely, phase
The blade directions of adjacent two groups of blades on the contrary, water plant can be cut from different perspectives, the weeds or fishing net after chopping due to more broken,
Blade would not be wound, so as to play protective effect to propeller.The setting of filter screen can guide current to pass through and water plant
Or the debris such as fishing net cannot pass through, water plant or fishing net can only from filtering network edge by, such filter screen then by chopping or not
The debris such as the water plant of chopping are all kept off outside propeller blade so that blade does not reach the debris such as water plant or fishing net, just not
It can be wound by them, protect propeller blade so that propeller works are smooth.
