Description
Technical field
The invention belongs to sea fishery fishing tool technical fields, more particularly to a kind of vertical type curved face V-arrangement grid web plate.
Background technique
The main function of trawl board is the horizontal expansion for expanding netting gear, and it is single boat trawl that increase trawlnet, which sweeps sea product,
Important accessory in fishing operation.At present web plate type common in trawl-net fishing have rectangle, ellipse, V-arrangement, vertical type curved face,
Vertical type curved face V-arrangement, split etc..Wherein, vertical type curved face chevron mesh plate uses the high aspect ratio knot at certain upper counterangle and receding angle
Structure design, feature is that expansionary force is big, and horizontal stability is good, is suitable for middle and bottom layers trawlnet.But due to by web plate weight itself and
The influence of structure, when carrying out surface trawl operation, it is more difficult to which guarantee makes web plate be in target water layer, furthermore, it is necessary to which fishing boat has
Higher towing tension and towing speed are not suitable for middle-size and small-size trawler and use.
Summary of the invention
The purpose of the present invention is to provide one kind be suitable for different gross ton fishing boats use, spreading performance is good, be suitable for table,
Middle and bottom layers trawling, the higher vertical type curved face V-arrangement grid web plate of hydrodynamic efficiency.
The purpose of the present invention is achieved through the following technical solutions: it is by baffle upper plate, high aspect ratio and with the V of receding angle
Shape curved surface wing plate drags guiding principle stiffening plate, chin spoiler composition, it is characterized in that being arranged between baffle upper plate and chin spoiler multiple big
Aspect ratio and with receding angle V-arrangement curved surface wing plate, each high aspect ratio and with receding angle V-arrangement curved surface wing plate between with equidistant
It arranges backward, setting drags guiding principle stiffening plate with each high aspect ratio and the V-arrangement curved surface wing plate with receding angle is connected, and whole is in grid
Form, baffle upper plate is identical with chin spoiler specification, and front end is wedge shape, and the length of wedge-shaped outer arcuate and radius of curvature and big
The radius of curvature of aspect ratio and the V-wing plate upper and lower ends outer arcuate with receding angle is identical.
For the prior art, remarkable result of the invention is:
1) a kind of web plate main body of vertical type curved face V-arrangement grid web plate is by multiple high aspect ratios and the V-arrangement with receding angle is bent
On the one hand face wing plate composition, the combination can give full play to that high aspect ratio structure induced drag is low, and the big advantage of expansionary force is another
Aspect wing plate plate face is made into curved, can reduce wing plate back vortex, improve web plate hydrodynamic performance；
2) a kind of web plate main body of vertical type curved face V-arrangement grid web plate is by multiple high aspect ratios and the V-arrangement with receding angle is bent
Face wing plate is composed, and the structure is other than the advantage performance with high aspect ratio web plate, moreover it is possible to play low aspect ratio web plate machine
The dynamic feature that property is good, operation is convenient, to improve the horizontal stability and restoration when web plate operation；
3) a kind of vertical type curved face V-arrangement grid web plate is used by multiple high aspect ratios and with the V-arrangement curved surface wing plate of receding angle
It is combined into the web plate main body an of low aspect ratio, can make web plate under conditions of obtaining same expansionary force, overall dimension miniaturization,
It so not only can be suitable for that medium and small fishing boat uses, but also can meet in table, middle layer water body operation the needs of to board spread force；
4) a kind of vertical type curved face V-arrangement grid web plate is used by multiple high aspect ratios and with the V-arrangement curved surface wing plate of receding angle
It is combined into the web plate main body an of low aspect ratio, the number of wing plate, receding angle, upper anti-can be adjusted according to the condition of fishing boat, netting gear
Angle, curve form and setting angle are to adapt to different trawling needs；
5) for a kind of vertical type curved face V-arrangement grid web plate in operation process, guide functions are equally played in the gap between grid, can
It is further reduced the influence of web plate back vortex, the lift resistance ratio of web plate is improved, can remain higher in wider range of angles of attack
Hydrodynamic performance.
