Abstract
The utility model relates to a large-mesh trawlnet comprising a sleeve net, a body net, a bag net and the accessory of the large-mesh trawlnet. The utility model is characterized in that the mesh size of the net sheets of the sleeve net at the net mouth and the body net is 1.0-2.5 meters. The large-mesh trawlnet has the advantages of small water resistance of unit area, expansion of the sweeping area and increase of the catching quantity. The utility model can be used for trawling in the 50-200 meters deep water.
Description
The utility model relates to a kind of netting gear.
The trawlnet that existing fishery is used, a kind of is the used trawlnet of inshore fishing, and its network interface place net sheet mesh size is between 10～40 centimetres, and this trawlnet so the unit are water resistance is big, is unfavorable for protecting juvenile fish because mesh is less.Another kind is the rope net that the ocean is used, and the mesh size of network interface place net sheet is between 16～30 meters, and this net only is applicable to the ocean operation, can not be used for off-shore operation.
The utility model purpose provides a kind of off-shore operation depth of water that is used at 50～200 meters, and the unit are water resistance is less, sweeps the long-pending bigger trawlnet in sea.
Solution of the present utility model is: a kind of Large-mesh trawlnet is made of sleeve net, body net, keed and accessory thereof, and the mesh size of network interface place net sheet should be 0.7 meter～3 meters, and optional 1 meter～2.5 meters, the best is 1.3 meters～1.7 meters.
Described sleeve net is by last sleeve net and the net of tucking inside the sleeve down constitutes.Upper and lower sleeve net is sewed up by some network of quadrilaterals sheets respectively and is formed, and upper and lower sleeve net removes lastblock net sheet, and the outside of other each piece net sheet is sewed up with the outside, forms the swallow-tail form net of tucking inside the sleeve.
Described body net is made up of 4～10 joints, each joint by more than two eight be stitched into big down young bag shape suitable for reading with lower net plate.Near the net sheet mesh size maximum at network interface place, the net sheet mesh size away from the network interface place is just more little more, and the net sheet mesh size of each joint body net is identical.
Described keed is to be made of a upper and lower opening bag of a size shape net sheet.
Described accessory comprises the headline that is contained in network interface upper end and is contained in float on the headline, is contained in the ground rope of network interface lower end and is contained in the sinker on the ground rope and be contained in side guiding principle on the netting gear side.
Described net sheet is a network of quadrilaterals purpose net sheet.
Tuck inside the sleeve end off the net and body holds stitching, body end off the net and keed upper end to sew up on the net.The sleeve net is inboard holds mid portion to form network interface on the net with body, and headline is pricked the first half at network interface, and float is pricked on headline.Ground rope is pricked the latter half at network interface, and sinker is pricked on ground rope.The side guiding principle is pricked on the side of net.
The utility model is compared with existing netting gear to have under the constant situation of towing tension, can increase the network interface area, increases that to sweep the sea long-pending, improves the advantage of single net output.
Accompanying drawing is an embodiment of the present utility model, wherein:
1, sleeve net 2, body net 3, keed 4, headline 5, ground rope
Embodiment: 212 orders * 600 horsepowers of two hull bottom trawlnets of 1500mm, adopt polyethylene quadrangle mesh net sheet to make, concrete data see the following form:
Steel wire rope, 73.48 meters of length, the ground rope of headline employing diameter 15.5mm adopts the steel wire rope of diameter 18.5mm, long 85.82 meters.It is 13 kilograms that float adopts its each buoyancy of plastic float of diameter 300mm, totally 55 floats, and gross buoyancy is 715 kilograms, sinker adopts plastic cement roller sinker, joins 831 kilograms of sinkers altogether, existing the getting final product of keed employing.Above each several part rolled to assemble up get final product.
Claims (2)
1, a kind of Large-mesh trawlnet is made of sleeve net [1], body net [2], keed [3] and accessory thereof, and it is characterized in that: the sleeve net [1] at network interface place, the net sheet mesh size of body net [2] is 1.0～2.5 meters.
2, Large-mesh trawlnet according to claim 1 is characterized in that: the sleeve net ［ 1 ］ at described network interface place, the net sheet mesh size of body net ［ 2 ］ is preferably 1.3～1.7 meters.
