Description
Technical field
The invention belongs to sea fishery fishing tool technical field, more particularly to a kind of vertical V-arrangement grid web plate.
Background technology
Trawl board is the important accessory in single boat trawl fishing operation, its main function is the horizontal expansion for realizing netting gear
, sea product is swept in increase.At present, there is rectangle, ellipse, V-arrangement, vertical using more web plate type in world's trawl-net fishing
（High aspect ratio）, vertical type curved face V-arrangement, slat formula etc..Wherein chevron mesh plate the advantages of be low cost, easy to operate, stability compared with
It is good, possess stronger obstacle-overpass ability and lodging resistance.But since its plate face form is substantially similar to rectangular otter board, make
Back can form larger vortex during industry, so the expansion force difference of chevron mesh plate, hydrodynamic efficiency be not high.Although China's fishery
Worker has carried out some improvement, such as plate face is made nearly ellipse, or slot etc. is opened up among web plate, is carried with this
Its high hydrodynamic efficiency, but overall hydrodynamic efficiency is still in reduced levels.
According to the operation principle of web plate, high aspect ratio structure helps to reduce streaming for web plate both ends, reduces luring for web plate
Resistance is led, improves the lift resistance ratio of web plate, and then improve the efficiency of web plate.And bottom trawlnet is generally made due to the limitation in seabed
It is poor with low aspect ratio web plate, hydrodynamic performance.Therefore, the hydrodynamic performance of low aspect ratio web plate how is improved, becomes net
Difficult point in harden structure optimization design.
The content of the invention
The purpose of the present invention is design it is a kind of by multiple high aspect ratios and with receding angle V-wing plate be composed it is small
The vertical V-arrangement grid web plate of aspect ratio, has and is used suitable for different gross ton fishing boats, the operation of different water levels water body, stability
The advantages of more excellent, lodging resistance is more preferable, and hydrodynamic efficiency is high, and web plate back vortex is few.
The purpose of the present invention is achieved through the following technical solutions：It by baffle upper plate, high aspect ratio and with receding angle V
Shape wing plate, drag guiding principle reinforcing plate, chin spoiler composition, it is characterized in that baffle upper plate is identical with chin spoiler specification, front end is wedge shape,
Rear end is arc, and multiple high aspect ratios and the V-wing plate with receding angle, each wing plate are set between baffle upper plate and chin spoiler
Upper and lower side be connected along the angle of baffle upper plate and chin spoiler front end wedge shape with baffle upper plate and chin spoiler, with equidistant
Setting arranged in parallel backward, and set between baffle upper plate and chin spoiler and drag guiding principle reinforcing plate, and the shape that is connected with each wing plate
Into the web plate main body of a low aspect ratio structure, overall formula in form of a grid.
Compared with prior art, remarkable result of the invention is：
1）A kind of vertical V-arrangement grid web plate is using multiple high aspect ratios and has the combination of the V-wing plate of receding angle, can
It is low to give full play to high aspect ratio wing plate induced drag, the high advantage of expansionary force, improves the hydrodynamic efficiency of common web plate；
2）A kind of vertical V-arrangement grid web plate is used by multiple high aspect ratios and the V-wing plate with receding angle is combined into
One low aspect ratio structure can keep that low aspect ratio web plate mobility is good, the convenient advantage of operation as web plate main body；
3）The high aspect ratio that a kind of vertical V-arrangement grid web plate uses and the V-wing plate with receding angle, compared to ordinary rectangular
Web plate, has certain receding angle and the upper counterangle.The advantage of increase receding angle is to reduce the power that incoming is centrally formed with wing plate
Square, is more advantageous to improving the horizontal stability of web plate, and the advantage for increasing the upper counterangle is to improve the energy that web plate crosses seabed obstacle
Power, increases the lodging resistance of web plate entirety（Vertical stability）；
4）A kind of vertical V-arrangement grid web plate by multiple high aspect ratios and with receding angle V-wing plate be combined into it is one small
The web plate main body of aspect ratio, can adjust the number and setting angle, each wing plate of high aspect ratio wing plate according to the condition of fishing boat, netting gear
The angle at receding angle and the upper counterangle is to adapt to different job requirements；
5）A kind of vertical V-arrangement grid web plate can make web plate under the conditions of equal expansionary force is obtained, overall dimension miniaturization, this
Sample not only can suitably medium and small fishing boat use, but also can meet in table, middle level water body operation the needs of to board spread force；
6）A kind of vertical V-arrangement grid web plate is in operation process, by the guide functions that the gap between grid is played, phase
Than the influence that conventional low aspect ratio web plate can reduce web plate back vortex, higher hydrodynamic(al) can be maintained in wider range of angles of attack
Power performance.

Embodiment
The embodiment of the present invention is described in further detail below in conjunction with brief description of the drawings, but the present embodiment is not used to limit
The system present invention, every similar structure using the present invention and its similar change, should all be included in protection scope of the present invention.
As shown in Fig. 1 to Fig. 3, a kind of vertical V-arrangement grid web plate that the embodiment of the present invention is provided, its by baffle upper plate 1,
High aspect ratio and with receding angle V-wing plate 2, drag guiding principle reinforcing plate 3, chin spoiler 4 is formed, in baffle upper plate 1 and lower water conservancy diversion
Multiple high aspect ratios and the V-wing plate 2 with receding angle are equipped between plate 4 at equal intervals, drags guiding principle reinforcing plate 3 and each high aspect ratio
And the V-wing plate 2 with receding angle is sequentially connected, the web plate main body of a low aspect ratio structure is formed.
The baffle upper plate 1 is identical with 4 specification of chin spoiler, and one end is wedge shaped, and the other end is arc-shaped.
Each high aspect ratio and with receding angle V-wing plate 2 specification it is identical, structure is V-arrangement, symmetrical above and below, and
Meeting stream direction in wing plate has certain retrogressing angle.
Described to drag in guiding principle reinforcing plate 3 equipped with draging guiding principle stent, plate face is parallelogram sturcutre, the angle of its front and back end with it is upper
