Abstract
The utility model relates to a fishing net, in particular to a fishing net for towboat, comprising a drag rope, a float line, a sinker line and a net handle. The knot of the net handle and an upper pull rope is positioned behind the knot of the net handle and a lower pull rope; the cross section of the opening of the fishing net is in trapezoid shape which contracts along with the drooping of the fishing net; and the knot of the net handle and the upper pull rope forms an acute angle with the knot of the net handle and the lower pull rope and with the sinker line, and the angle is smaller than 70 degrees and larger than 15 degrees, with the optimal angle being between 55 degrees and 25 degrees. The fishing net has the advantages that the cross section of the opening of the fishing net is in trapezoid shape when the towboat pulls the fishing net, therefore, the dragging power of the towboat is reduced, the oil consumption is reduced and the fishing yield is increased.
Description
Technical field
The utility model relates to a kind of fishing net, the used fishing net of especially a kind of towboat.
Background technology
The fishing net of the present towboat that generally adopts, form by floating guiding principle, heavy guiding principle, net hand and mesh, generally speaking, the net hand equates in the position, node place of stay cord up and down, so when under the effect of the speed of ship, water speed, advancing, present after fishing net trails in water cylindric, so bear identical pressure up and down, as a gassiness sack, resistance is very big.Such pressure passes to boats and ships then needs very big power to go to drag it, and the fuel oil that towboat consumes is many, and fishing net is difficult for crashing into too dark seabed.
Summary of the invention
The utility model be to provide a kind of go into extra large sinker dark, drag than the labour-saving fishing net.
The utility model is achieved in that a kind of fishing net, comprises tow strap, headline, infraclass, net hand, and the node of net hand and last stay cord is positioned at after the node place of net hand and following stay cord.
The opening part cross section of fishing net is trapezoidal, and fishing net is sagging to be trapezoidal and to dwindle.
And the node of net hand and last stay cord, acutangulate with the node of net hand and play stay cord and with the angle of heavy guiding principle, angle is less than the sounds of 70 degree to 15 degree, better angle be 55 spend spend to 25 between.Best angle is that 45 degree are between 40 degree.
Advantage of the present utility model be since behind the last node in following node, so when towboat pulling fishing net, the opening part cross section of fishing net is trapezoidal, fishing net is sagging to be trapezoidal and to dwindle, so the floating guiding principle on the top of fishing net does not have pressure drag, the power that drags of towboat reduces, and the degree of depth that fishing net sinks to the sea increases, so reduced the oil consumption of fishing boat, increased the results of fishing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Wherein 1 is that last stay cord, 2 is following stay cord, and 3 be the last node of net hand and last stay cord, and 4 be the net hand and the following node of following stay cord, and 5 is to float guiding principle, and 6 is to sink guiding principle, and 7 is the fishing net eye, and 8 is the net hand.Because of rear portion, the too big Therefore, omited of fishing net mesh.
Embodiment
A kind of fishing net comprises tow strap, floating guiding principle, heavy guiding principle, net hand, and behind the last node place of net hand and last stay cord in the following node place of net hand and following stay cord.
In the fishing net of towboat, this kind fishing net is generally advanced in tow together by two ships, through after the certain sea area, thereby the fishing net of road through the marine site is obtained results therein.A stay cord that links to each other with every fishing boat, this stay cord is divided into stay cord and following stay cord after leaving a segment distance of towboat, article two, connect by floating guiding principle between the last stay cord of ship, floating guiding principle is a kind of rope that has buoyancy, article two, connect by heavy guiding principle between the following stay cord, the effect of heavy guiding principle is to make fishing net to sinking, because the fish in field, deep-sea can be more more.The net hand connects to be gone up between stay cord and the following stay cord, the node of its net hand of original fishing net and last stay cord and following stay cord is substantially at same position, as receive when net its site position or length identical, and both are basic identical on the upright position during working time, thus whole net presents taper shape when work.
And the net hand that is not both of the present utility model connect to be gone up behind the node of stay cord in connecting the node of stay cord down.When receiving net, the node of net hand and last stay cord is positioned at after net hand and the drop-down knot point.Thereby upon deployment, last node is after following node, and promptly the node of net hand and last stay cord will be longer than the length of the node of net hand and following stay cord apart from towboat apart from the length of towboat.
Floating guiding principle can be neatly and node between the last stay cord, regulate the length between the node at any time, thereby can regulate the downward degree of depth of fishing net.
And the node of net hand and last stay cord, acutangulate with the node of net hand and play stay cord and with the angle of being formed of heavy guiding principle, angle less than 70 degree between 15 degree, best angle is between 55 degree are spent to 25.See from the side more to like acute triangle, thus also difference to some extent on the weaving manner of mesh, and no longer side and net hand weaving are made into semicircular arc.Better angle is that 45 degree are between 40 degree.
Claims (6)
1. a fishing net comprises tow strap, headline, infraclass, net hand, it is characterized in that: the node of net hand and last stay cord is positioned at after the node of net hand and following stay cord.
2. fishing net according to claim 1 is characterized in that: the node of net hand and last stay cord, acutangulate with the node of net hand and following stay cord and with the angle of heavy guiding principle.
3. fishing net according to claim 2 is characterized in that: above-mentioned angle is between 70 degree are spent to 15.
4. fishing net according to claim 3 is characterized in that: the angle of above-mentioned the best is that 55 degree are between 25 degree.
5. fishing net according to claim 4 is characterized in that: its angle is that 45 degree are between 40 degree.
