Abstract
It closes up to fish the utility model discloses a kind of bottom and revolves net, including tubular dictyosome；Wherein tubular dictyosome one end is formed by knots tied closed end, other end net bottom mouth penetrates bottom steel cable, steel strand rope is equipped with close to bottom steel cable side, and by the plummet being distributed on steel strand rope, it further include the annulus penetrated on steel strand rope, by being distributed between adjacent plummet, above-mentioned bottom steel cable, steel strand rope and annulus pass through a fixed rope and be fixedly secured to one another bottom steel cable, steel strand rope and annulus the annulus, a main steel rope is penetrated in each described annulus, by drawing in two adjacent rings.Therefore, by main steel rope, by net bottom opening's edge river bed or seabed, actively tightening forms a whole string bag, and receiving makes after net the tightening of net bottom mouth lift out the water surface upward, and another knotted end of dictyosome is then downward, and being housed in the intracorporal fish of net, none is slipped through the net and escapes.It is few to solve traditional fishnet netting amount, is easy the problem of escaping.
Description
Technical field
It fishes the utility model relates to one kind and revolves net, specifically a kind of bottom, which closes up to fish, revolves net.
Background technique
Traditional to fish that revolve net tightened by traction steel rope of cable into closed end in the dictyosome one end impaled, the other end is inwardly curved
One section of dictyosome is rolled over, using connecting back wall between this section of dictyosome and main mesh at regular intervals into a base opening string bag, and in base opening
The bending part of the string bag is by being intervally distributed with plummet.When casting net, a hand catches the major network part of traction steel rope of cable and folding, another
After hand catches the base opening string bag, whole dictyosome is thrown in water, falls its rounded opening of base opening string bag in throwing network process
Enter in water.Drawing dictyosome by traction steel rope of cable when hauling makes its base opening string bag gradually be tightened to closure, net under the action of plummet
The fish entered enters in the base opening string bag.Although can net enter some fishes, during receiving net, if the fish number that enters of net is big
In the case of, due to the design structure defect of the fish base opening string bag, when receiving net, fishnet base opening is in gradually distraction procedure due to dictyosome
Middle part can not be closed, this just provides the chance escaped to fish, and most fishes can all run away, and only can catch a small amount of fish, can not
It catches all in one draft.Therefore, it is necessary to be subject to improve and perfect.
Summary of the invention
In view of above-mentioned status, the utility model, which provides a kind of bottom and closes up to fish, revolves net, make its net bottom opening's edge river bed or
Actively tightening forms a whole string bag in seabed.Receive net when net bottom mouth tightening upward first go out the water surface, the fish that net enters none slip through the net.
The technical solution of the utility model is: a kind of bottom, which closes up to fish, revolves net, including tubular dictyosome；Wherein cylinder mesh
Body one end is formed by knots tied closed end, and other end net bottom mouth penetrates bottom steel cable, is equipped with steel strand rope close to bottom steel cable side, and by interval
The plummet being distributed on steel strand rope, further includes the annulus penetrated on steel strand rope, the annulus by be distributed in adjacent plummet it
Between, above-mentioned bottom steel cable, steel strand rope and annulus pass through a fixed rope and bottom steel cable, steel strand rope and annulus are fixed to one another company
It connects, a main steel rope is penetrated in each described annulus, by being drawn in two adjacent rings.It falls into the water when throwing net,
River bed (or seabed) is fallen under the gravity of plummet, is tightened to and is left the water along river bed (or seabed) by traction main steel rope,
Its entire dictyosome is set to form a big string bag.
Among the above, annulus is located at least in the two sides of a plummet.
Further, annulus is fixed on bottom steel cable and steel strand rope.
Among the above, fixed rope is fixed on bottom steel cable and steel strand rope after the two sides of each plummet knot.Prevent plummet
Vibration keeps the stability of uniform position.
Among the above, net bottom mouth closes its tightening by lifting main steel rope, and makes the net bottom mouth of dictyosome towards upper, and another
Knotted end forms net bottom downward.
The utility model beneficial effect is: the bottom of the design, which closes up to fish, revolves net, mainly utilizes main steel rope by net bottom mouth
Along river bed or seabed, actively tightening forms a whole string bag.Receiving tightens net bottom mouth after netting lifts out the water surface upward, and net
Then downward, as long as covering on the intracorporal fish of net, none slips through the net and escapes another knotted end of body.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is Fig. 1 partial schematic diagram；
Fig. 3 is Fig. 1 seine state reference map.
Specific embodiment
Below in conjunction with figure embodiment, the utility model is described in further detail.
See that Fig. 1 closes up to fish to a kind of bottom shown in Fig. 2 and revolve net, including tubular dictyosome 1, the present embodiment are in tubular dictyosome
1 one end fastens a knot and forms closed end, and the other end staggeredly penetrates bottom as net bottom mouth, and in each mesh of net bottom mouth
Steel cable 2 is equipped with steel strand rope 3 close to 2 side of bottom steel cable, by being intervally distributed with plummet 4 on the steel strand rope 3, and penetrates steel
Annulus 6 on twisted rope 3, the annulus 6 of the present embodiment is by being distributed between adjacent plummet 4.Bottom steel cable 2, steel among the above
Twisted rope 3, annulus 6 and plummet 4 are knotted bottom steel cable 2, steel strand rope 3, annulus 6 and plummet 4 fixation by a fixed rope 5 each other
Connection, ensure that the connection between bottom steel cable 2 and steel strand rope 3, while also preventing the vibration of annulus 6 and plummet 4.Described
A main steel rope 7 is penetrated in each annulus 6, by drawing in two adjacent annulus 6 after surrounding.It falls into the water when throwing net,
River bed (or seabed) is fallen under the gravity of plummet 4, and proposition water is tightened to along river bed (or seabed) by traction main steel rope 7
1 one end of dictyosome in face, tying forms net bottom, its entire dictyosome is made to form a big string bag.When fish, by the knotted end of dictyosome 1
Fish network interface is formed after opening.
Among the above, it in addition to annulus 6 is located at the two sides of each plummet 4, can be distributed according to the specification difference of dictyosome
The two sides of every two plummet 4.
Further, annulus 6 can also be also secured to steel strand rope 3 and bottom steel cable 2 in addition to being fixed on steel strand rope 3
On.
Among the above, fixed rope 5 knots in the two sides of each plummet, is fixed on bottom steel cable 2 and steel strand rope 3.Prevent lead
Vibration is fallen, the stability of uniform position is kept.
Among the above, net bottom mouth makes its tightening closing by lifting main steel rope 7, and makes the net bottom mouth of dictyosome 1 towards upper, and another
One knotted net body 1 forms net bottom downward.It avoids the shoal of fish caught to escape, realizes a net and throw into.
Above-mentioned fishnet cast net mode and tradition rotation net mode it is essentially identical.
Fig. 3 provides the state reference map after receiving net.By normally cast net after net bottom mouth enter water it is bottomed after, traction main steel rope 7 by
Net bottom mouth is tightened to by step to be continued to lift dictyosome 1, its net bottom mouth is made to be gradually exposed the water surface upward, and another knotted end of dictyosome 1
Gradually sink to forming one big fishnet pocket under the action of the shoal of fish weight caught, makes the fish covered in dictyosome 1 that can not slip through the net and escape
It is de-.
