Abstract
The utility model provides an otter board with combination formula buoyancy pterygoid lamina, a trawlnet horizontal expansion device that that uses on the trawlnet fishing tackle has a combination formula buoyancy pterygoid lamina is related to, reinforcing plate in the adoption, middle reinforcing plate, the bottom reinforcing plate, the frame is formed in pterygoid lamina and stiffened edge assembly, the pterygoid lamina becomes crank slot shape, pterygoid lamina and last reinforcing plate, middle reinforcing plate, the bottom reinforcing plate all adopts welded connection, characterized by pterygoid lamina inslot inlays the cystosepiment as the buoyancy filler material, the pterygoid lamina groove face covers the engineering plastics board and assembles box -like buoyancy pterygoid lamina in groups with the screw, above -mentioned panel system has prefabricated screw, adopt screwed connection, the stiffened edge is the semicircle strip, and semicircle diameter is the same with the thickness at combination formula buoyancy pterygoid lamina edge, and at the prefabricated screw of combination formula buoyancy pterygoid lamina side, the screw is installed at combination formula buoyancy pterygoid lamina edge for the stiffened edge. A demand that otter board with combination formula buoyancy pterygoid lamina is suitable for the otter -trawl, deep water layer trawlnet and different water layer trawlnets of trawlnet at the middle and upper levels.
Description
Technical field
The utility model relates to the trawlnet horizontal expansion device with combined type buoyant wing plate that Trawl gear uses.
Background technology
Trawlnet horizontal expansion device also claims web plate, is the important component part of Trawl gear.In the process that trawlnet pulls in water, network interface can open by the tension force being assemblied in the web plate generation that trawlnet both sides are draged on guiding principle, and therefore, the performance of web plate is directly connected to fishery harvesting efficiency and the economic benefit of trawling.In the prior art, according to the demand of dissimilar trawlnet, the pattern of web plate is varied, the web plate pattern used both at home and abroad at present mainly contains rectangular otter board, oval web plate, vertical V type otter board etc., the web plate of each pattern also can change structural parameters because of instructions for use, and therefore mesh-plate structure is more diversified.But the material making web plate is more single, and namely the main material of Long-Time Service is iron and steel, and steel web plate has certain advantage, solid and reliable, shock-resistant etc.But along with the development of fishery, some shortcomings of iron and steel web plate self govern the raising of the aspects such as catching rate, and iron and steel easily corrodes in the seawater, and preponderance, be not easy to the folding and unfolding of netting gear, increase the difficulty of operation on the sea; It is excessive that the problem of weight also causes iron and steel web plate to conduct oneself with dignity when submarine, increases towrope resistance, and also bull trawl of conducting oneself with dignity during layer towing in the seawater impacts, and needs to be equipped with in addition the weight that steel web plate is offset in float or floating chamber.At present, a small amount of glass-reinforced plastic material that uses is had to make web plate, the weight of this type of web plate comparatively steel web plate has some superiority, but due to the characteristic of glass-reinforced plastic material self, require higher to web plate manufacture craft, and plastotype process need strictly controls, the web plate be made into is not easy to maintenance and repair in the later stage uses, and the web plate of this kind of material is the main trend improved of non-web plate performance also.In general, web plate material and web plate assembling mode all need to improve, to improve the performance of web plate in trawling and efficiency.
Summary of the invention
The utility model technical issues that need to address are a kind of web plates with combined type buoyant wing plate of design, to improve the performance of web plate in trawling and efficiency.
The technical solution of the utility model adopts upper reinforcing plate, middle stiffener, bottom stiffener, wing plate and stiffened edge to assembly framework, wing plate becomes crank slot shape, wing plate and upper reinforcing plate, middle stiffener, bottom stiffener all adopt and are welded to connect, it is characterized in that the embedded cystosepiment of wing plate groove is as buoyancy filler material, wing plate groove face covers engineering plastic flitch and is assembled into combined type buoyant wing plate with screw, above-mentioned sheet material is shaped with prefabricated screw, adopts screw to connect; Stiffened edge is semicircle strip, and half diameter of a circle is identical with the thickness at combined type buoyant wing plate edge, and at the prefabricated screw of combined type buoyant wing plate side, stiffened edge screw is arranged on combined type buoyant wing plate edge.
The combined type buoyant wing plate of the utility model owing to adopting, wing plate wherein, as the integrally-built support of web plate, ensures the integrally-built rigid demand of web plate; Cystosepiment can provide the buoyancy required for web plate according to demand; Engineering plastic flitch has high strength, and can not corrode, and can ensure smoothness of the surface, reduces the water resistance suffered by web plate, improves the overall hydrodynamic performance of web plate.Combined type buoyant wing plate can a plate multiplex, be suitable for otter-trawl, the demand of profundal zone trawlnet and at the middle and upper levels trawlnet different water levels trawlnet.Combined type buoyant wing plate can regulate web plate buoyancy size, controls the trawling that it is suitable for different water levels, improves the availability of web plate, has better economic benefit.
Accompanying drawing explanation
What Fig. 1 represented is a kind of mesh-plate structure schematic diagram with combined type buoyant wing plate.
What Fig. 2 represented is by stiffened edge fixing threaded hole and. the schematic cross-section of the combined type buoyant wing plate of three layers of fixing threaded hole.
The schematic cross-section of the combined type buoyant wing plate that what Fig. 3 represented is by two-layer fixing threaded hole.
Embodiment
Embodiment 1 (see accompanying drawing): by upper reinforcing plate 1, middle stiffener 4, bottom stiffener 5, wing plate 2, 3, 12, 13 and stiffened edge 7 form framework, wing plate becomes crank slot shape, wing plate and upper reinforcing plate, middle stiffener, the connected mode of bottom stiffener all adopts and is welded to connect, the embedded cystosepiment 9 of wing plate groove is as buoyancy filler material, wing plate groove face 8 covers engineering plastic flitch 10 and is assembled into combined type buoyant wing plate with screw, namely combined type buoyant wing plate adopts wing plate, cystosepiment and each one deck of engineering plastic flitch, the prefabricated screw 15 of above-mentioned sheet material, 16, screw 11 is adopted to connect, stiffened edge is semicircle strip, and half diameter of a circle is identical with the thickness at combined type buoyant wing plate edge, and at the prefabricated screw 14 of combined type buoyant wing plate side, stiffened edge screw 6 is arranged on combined type buoyant wing plate edge.
Embodiment 2: according to the embodiment described in embodiment 1, integral net board size is high 5m × wide 2m.
