Abstract
The utility model discloses a trawl net plate in different water layers. The trawl net plate comprises a net plate body which comprises an upper face plate, a lower face plate and a steel warp plate. The upper face plate and the lower face plate are arranged on two sides of the steel warp plate. A dragging iron is arranged at the lower end of the lower face plate, and an accommodating portion used for placing balance weight plates is arranged in the dragging iron. Through increase or decrease of the balance weight plates on the net plate, the weight of the net plate can be adjusted, so the net plate can be used in the different water layers.
Description
Technical field
The utility model relates to the web plate that the expansion netting gear is used in the single boat trawl operation.
Background technology
Early stage otter-trawl operation uses framework to fix the shape of network interface.But for comparatively large-scale trawlnet, because the size of framework such as is operated, lays at the restriction of aspect, great restriction has also been received in its development.In the twenties in 20th century, people have invented web plate, have substituted framework, so just make netting gear break away from the restriction of framework, make the possibility of the oriented large scale development of netting gear.
The web plate General Requirements its under water during operation hydrodynamic performance reach optimum regime.Should be according to the sea area characteristics during use, the power of fishing boat, fish for object, operation fishing ground, fish for water layer, facility condition etc., select suitable web plate type.Traditional a kind of web plate can only be applicable to use in a water layer,, when fishing in the middle level, ocean, can only use corresponding marine site, middle level web plate that is; When bottom is fished for, then need again to change the bottom marine site web plate that is applicable to accordingly the bottom use for needs.If when so just having caused same fishing boat need to carry out simultaneously fishing for of marine site, middle level and bottom marine site, need to carry simultaneously marine site, middle level web plate and bottom marine site web plate, because web plate itself has larger quality and face area, the inconvenience that has caused web plate to carry.
Summary of the invention
For the deficiencies in the prior art, a kind of change water layer trawl board is provided, can under the condition of not changing web plate, realize that web plate uses at different water layers.
The utility model is achieved through the following technical solutions: become the water layer trawl board, comprise the web plate body, described web plate body comprises top panel, lower faceplate and warp plate, described top panel and lower faceplate are arranged at the warp plate both sides, be provided with in described lower faceplate lower end and drag iron, in the described accommodation section that is provided with in the iron for placing Weight plate of dragging.
In the technique scheme, described accommodation section comprises horizontally disposed base plate, is fixedly installed vertical baffle plate in the both sides of base plate, and the described accommodation section is fixedly installed on the web plate body by wear bolt in base plate.
The utility model compared with prior art has following beneficial effect: by increasing at web plate or reducing Weight plate, the weight of regulating web plate is so that web plate can use in different water layers.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation that the utility model drags the iron part.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1 to Fig. 3, become the water layer trawl board, comprise web plate body 1, described web plate body 1 comprises top panel 2, lower faceplate 3 and warp plate 4, described top panel 2 and lower faceplate 3 are arranged at warp plate 4 both sides, in described upper and lower panel, be provided with the sealing 20 that water supply stream passes through, be provided with in described lower faceplate 4 lower ends and drag iron 5, in the described accommodation section 6 that is provided with in the iron 5 for placing Weight plate 7 of dragging.
Described accommodation section 6 comprises horizontally disposed base plate 60, is fixedly installed vertical baffle plate 61 in the both sides of base plate 60, and described accommodation section 6 is fixedly installed on the web plate body 1 by wear bolt 62 in base plate 60.
When needs carry out operation in the deep layer waters, can in accommodation section 6, install the Weight plate 7 of some additional, increase the weight of web plate body 1, so that web plate can carry out operation in the deep layer waters; When needs carry out operation in the waters, middle level, only need to remove the Weight plate 7 that accommodation section 6 arranges, thereby do not need the web plate that again more renews, use convenience very.
Because for sealing 20, generally be the little passage of the large water side of water intake end opening opening, the problem that the structure of this passage is easy to produce is to drag when capable in subsea level at web plate, and larger stone etc. easily stop up sealing 20, affects the hydrodynamic performance of web plate.In the situation that seriously can cause web plate to occur teetertottering or the situation of flip horizontal.For above-mentioned situation, filter screen 70 is set in web plate sealing 20, the number of the mesh of described filter screen should not arrange too much, otherwise can affect the hydrodynamic performance of web plate.
