Abstract
The utility model provides a bottom trawl sinker line structure comprises a lower line, a plurality of connectors, a steel rope and iron rings. The lower line is connected to a net by winding and sewing. One ends of the connectors are arranged on the lower line. The steel rope is connected to the other ends of the connectors. The iron rings are arranged among the connectors. According to the bottom trawl sinker line structure, the steel rope penetrates the iron rings and rubber sheets alternately, when the lower line fitting to the bottom is dragged, the iron rings and the rubber sheets rotate with the dragging of a fishing boat, the dragging resistance is reduced accordingly, the degree of sediment embedding is lowered, and sinker weighing adjustment is simplified greatly through the connecting manner; frictions among the iron rings is buffered through the rubber sheets, and the durability of the sinker line is improved; the lower line can be connected to the sinker line conveniently through the connectors, working intensity of the assembling operation is reduced, and fishing cost is saved.
Description
Technical field
The utility model relates to ground rope structural design in bottom trawlnet, particularly a kind of otter-trawl ground rope structure.
Background technology
Bottom trawlnet ground rope major function is to keep network interface expansion, make netting gear infraclass can be close to seabed and move, generally adopt at present iron chains as the main selection of ground rope, be mounted to infraclass by blind stitching, be connected with netting gear, move although iron chains can make netting gear be close to seabed preferably, easily embed silt, towrope resistance is larger, the counterweight adjustment of iron chains ground rope is more loaded down with trivial details simultaneously, therefore in order to make up the defect of above-mentioned iron chains ground rope, need a kind of optimal design, have no at present relevant report.
Utility model content
The utility model provides a kind of otter-trawl that can make to reduce the otter-trawl ground rope structure that embeds silt degree, reduces towrope resistance.
For solving the problems of the technologies described above, the utility model otter-trawl ground rope structure, comprising: infraclass, and described infraclass is connected with etting by blind stitching; Connector, the quantity of described connector is multiple, one end of multiple described connectors is arranged in described infraclass; Steel wire rope, steel wire rope is connected with the other end of described connector; And iron hoop, described iron hoop is arranged between multiple described connectors.
Preferably, between multiple described connectors, the quantity of described iron hoop is two.
Preferably, be provided with sheet rubber in the outside of connector between adjacent described iron hoop, between described iron hoop and described in two ends.
The utility model otter-trawl ground rope structure iron hoop and sheet rubber are respectively gone here and there and are worn to steel wire rope, when infraclass subsides end towing, iron hoop and sheet rubber rotate with fishing boat towing, thereby reduce towrope resistance, reduce to embed silt degree, this connected mode has been simplified sinker counterweight adjustment work greatly; Sheet rubber can reduce the proportion of iron hoop, meeting under the requirement of settling capacity configuration, also can reduce to embed silt degree; Friction between sheet rubber buffering iron hoop, increases ground rope durability; Connector can facilitate being connected of infraclass and ground rope, reduces the labour intensity of installment work, saves fishery cost.
Brief description of the drawings
Fig. 1 is the utility model otter-trawl ground rope structure structural representation.
Description of reference numerals in the utility model otter-trawl ground rope structure accompanying drawing:
1-connector 2-iron hoop 3-sheet rubber
4-steel wire rope 5-infraclass 6-etting
Embodiment
Below in conjunction with accompanying drawing, the utility model otter-trawl ground rope structure is described in further detail.
As shown in Figure 1, the utility model otter-trawl ground rope structure adopts iron hoop 2 strings to wear to steel wire rope 4, and every adjacent two iron hoop 2 use sheet rubbers 3 separate, and every 2 iron hoops 2 arrange 1 connector 1.Ground rope is connected to infraclass 5 by connector 1, and steel wire rope 4 is connected with infraclass or manrope by the Chinese lute ring at two ends, and infraclass 5 is connected with etting 6 by blind stitching.
The utility model otter-trawl ground rope structure iron hoop and sheet rubber are respectively gone here and there and are worn to steel wire rope, when infraclass subsides end towing, iron hoop and sheet rubber rotate with fishing boat towing, thereby reduce towrope resistance, reduce to embed silt degree, this connected mode has been simplified sinker counterweight adjustment work greatly; Sheet rubber can reduce the proportion of iron hoop, meeting under the requirement of settling capacity configuration, also can reduce to embed silt degree; Friction between sheet rubber buffering iron hoop, increases ground rope durability; Connector can facilitate being connected of infraclass and ground rope, reduces the labour intensity of installment work, saves fishery cost.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
