Description
Technical field
The invention belongs to technical field of ships, are related to a kind of fishing boat, especially a kind of structure improved boom type trawler
Ship.
Background technique
In reality, since the tonnage of fishing boat is smaller, it is affected when carrying out long range fishing by stormy waves, especially cantilever crane
Formula trawler, because the trawlnet cantilever crane being arranged in Ship Structure is generally longer, under non-job state, trawlnet cantilever crane is in straight
The upper end of vertical state, cantilever crane causes fishing boat in stormy waves much higher than the residential area on fishing boat so that the center of gravity of fishing boat entirety is higher
Stability it is poor, secondly under job state, trawlnet cantilever crane be in horizontality, and the free end stretching Ship Structure of cantilever crane is very
It is more, and the drag force by fishing net is larger, and fishing boat is caused to be easy to pour out or destroy jib structure, so how to improve
The stability of trawler and effective use wave energy etc. are our problems to be solved.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, proposes a kind of structure improved boom type and drag

On the rotor plate 10 is rotatably arranged in the grooves on two sides 8b of ontology 8d, by by the rotor plate 10 of bow be tuned into
Angle on forward direction will be tuned into downward angle backward by the rotor plate 10 of stern, enable ship when fully loaded voyage
Bigger climbing power is accessed, drinking water is reduced；Opposite, it will be tuned into downward angle forward by the rotor plate 10 of bow, will leaned on
The rotor plate 10 of stern is tuned into angle upward backward, and ship is enabled to increase drinking water when zero load is advanced, and improves ship
The stability of oceangoing ship navigation, secondly by the angular adjustment of head and the tail rotor plate 10 at symmetrically upwardly or downwardly, can reduce ship
Oceangoing ship trim amplitude can be increased to subtract and be shaken effect finally by the angle of adjustment rotor plate 10 with the forced area of Indirect method stabilizer 8
Fruit；Furthermore the speed of two 11c shaft of motor output is adjusted by one 11a of gear and two 11b of gear, and gear drive has
Have the advantages that compact-sized, transmission efficiency is high, long service life.
Specifically, two 10d of several through-holes is offered on the rotor plate 10, passes through bracket in two 10d of through-hole
Be installed with one 10b of generator, the end of the input shaft of one 10b of generator is equipped with one 10c of impeller, one 10c of impeller with
Two 10d of through-hole coaxial arrangement, the generator 5d are electrically connected with battery 3f.
When two 11c of motor driving rotor plate 10 is rotated around one 10a of shaft, water flow can scour two 10d of through-hole,
One 10c of the impeller rotation in two 10d of through-hole is driven, so that one 10b of generator is generated electricity, then electric energy is stored in battery 3f,
Energy regenerating is realized, and reduces impact of the water flow to rotor plate 10, avoids two 11c of motor because frequently being impacted
And be damaged, extend the service life of rotor plate 10.
Preferably, the thickness of 10 cross section of rotor plate is gradually reduced from one end to the other end, 10 thickness of rotor plate compared with
The small outside for being mounted on groove 8b on one side reduces the resistance of seawater generation, next also reduces rotor when ship advances
The weight of plate 10 reduces by two 11c driving load of motor, i.e., energy saving, and can extend the use time of two 11c of motor.
Those skilled in the art can various modifications may be made to described specific embodiment, supplement or
It is substituted using similar method, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
