SU31340A1 - Seabed for fishing on the bottom - Google Patents

Description

The invention relates to seines for fishing on the bottom, consisting of a non-bottom network, spacer boards and tow ropes.

In the proposed net, a lower selection of the net is attached to the cables independent of the network body and serving to transfer the tractive forces of the net. In order to facilitate the casting of the seine into the water, it is provided with a mesh lining fixed to the wings of the net at some distance from the rope. Side grids reinforced to the body of the net are intended to keep the fish in the net. Protection of the coil from wear is achieved by using a plate with holes or notches located under the base of the coil reinforcement.

FIG. 1 is a perspective view of a seine; FIG. 2 is the same view in another version; FIG. 3 is a view of the seine from above; FIG. 4 is a variant of the net in FIG. 2; FIG. 5 is a top view of the upper part of the seine in FIG. 2; FIG. 6 - the same seine is suitably improved; FIG. 1-9 - other improvements of the seine (bottom view); Fig, 10 and 11-part reinforcement of the coil.

The proposed seine. (Fig. 1) contains a net /, blown upwards, which is dragged to the shore by means of m grams 3, 3 and long ropes 5, .5, attached to shields 6, 6, which provide for the opening of the net in width.

A substantial part of the invention consists in the abolition of the usual net bag and in the restriction of the net 7 on each side with a curb rope 8, 8 with a ballastum. Such an arrangement avoids the drawbacks of having a bag and a bead. It may be sufficient to prevent the fish from popping out from under the net of its edges when the bottom is uniform.

But usually, especially at the bottom of an irregular shape, it will be more desirable to use a seine in FIG. 2, in which the ropes 8 are split into two separate ropes P and //: one of these ropes or curb ropes 9 is attached, for example, in the rear part 0 to the other rope or to the coot ropes 4, transferring traction forces to it and continuation of the ropes 5. Preferably, for each of the ropes .5, a hook (not shown in the drawing) is placed in front of the binding point / 5. The distance is 10-75 or the length of the rope 11 is less than the length of the border rope 9 from the husky. end 14, so that all tensions produced by the ropes are transferred to the rope or the guy 7 /, while the curb ropes are flexible enough to follow their load and the contour of the seabed and prevent fish from leaving the net.

When pulling out the nets, the mote can be taken aboard with the help of cables, and not manually lift it loop by loop.

The motn 4 is equipped with a rope 18. similar to the usual board, but not presenting the inconvenience of the latter. This rope is really very short, only rat. veins to the width of the mote (while the normal bead is 30 to 40 m long), so the amount of deposition products it takes is insignificant. Without carrying any load, he is not capable of catching and thus causing spoilage. Finally, it is easy to supply it with coils that can pass over all obstacles.

The motn, being the only part that drags along the bottom, can be equipped with a leather apron or safety net, which was practically impossible for the lower part of the networks of all previous systems.

The body of the net has the sole purpose of being a curtain that prevents the fish from jumping out; the upper part, swollen thanks to floats and attaching the rope 16, forms the genus of the dome, which takes the fish.

For fishing on the bottom, which has irregular shapes, and we, the curb rope 9 can be supplied with a side net 17 (Fig. 4) hanging vertically loaded from the bottom, for example, chains; the marked net supplements the operation of the cable 9. The guys //, regardless of the net, can be taken aboard by means of a winch that can be done before the wind, which greatly facilitates the work with the net.

The proposed seine can be improved by adding a rigid or semi-semi: stiff reinforcement in the part lying in front of the tower, and at the shrouds //. These fittings may consist of a horizontal pole supported by two ridges: a pole.

the skates and legs form a small net with a pole.

In conventional nets, which present themselves as a real funnel, during the descent into the water, the latter penetrates approximately evenly into the whole net, with the net well inflating and reaching the bottom in the proper position. With the proposed device, the absence of the bag makes the seta somewhat unstable. To correct this deficiency (Fig. 8), it is good to add the device of the next device, telling the network an equilibrium. On the underside of the rider 22, located at the entrance to the windrow 4, two ropes 50, 5 / (Fig. 4) of equal length are attached, connected at their lower ends with a rope 52 having a load 53 in its lower part. the floats 54 are attached, either directly on them, or in the same way as when y StroyGstvo has a sinker 53. If necessary, we can arrange the sinkers 55 placed at the point / 5 of the halters 5.

When such a seine is in operation, the rope, the float of the back rope and the load of the ropes P ensure the stability of the net when lowering it into the water, which prevents its inversion.

This adaptation does not in the least interfere with catching, as it rubs the bottom only under the tomb; However, in order to avoid engagement with the ropes 50, 51 and 52 about the unevenness of the bottom and, in order not to cause accidents, the ropes can be given a low resistance so that they can break at the slightest obstacles.

In some cases with seines of FIG. 2 it happens that in front of the catcher 4 (fig. 5) there are sometimes side pockets 25, resulting from the fact that the wings 24 are not stretched, and that the water flow tends to push them back, while the fences 25 are 18 tons Nuts forward guys //. If there are no devices in the network to resist this distribution of forces, the loops of the network are stretched and deformed between points 25 and 26 and, the particles at the bottom, the deposition products, and so on. The pins are collected in the pocket of 2J, which causes the network to be defaulted and damaged.

To correct this flaw, the lower edge of the wings 2 # can be unfastened.

from the barrier 18 and from the curb ropes 9 between points 27 (fig. 6) and 28, which allows the wing to return to its normal position, eliminates the formation of pocket 23 and the stretching of loops between points 25 and 26. The lower edge of the wing between points 27 and 28 may be provided with a cable with weights or a chain in order to remain in contact with the bottom. In practice, you dreamed that, if we consider the curvature that ropes 9 take to points 25, then these ropes maintain curvature even when the edge of the wing is separated from fencing 18, and the ropes 9 and the reduced network work satisfactorily without nyat flaws.

Triangle 27-28-25 can be left empty, in which case the cable is provided with a curtain that prevents the fish from slipping. If desired, the triangle can be filled with parts of the nets of any shape or with a braided line, the ease of changing forms of which will be easily adapted to minor changes in the forms in this part. Of course, the shape and dimensions of this triangle are determined in each individual case according to the degree of necessity in preliminary tests, taking into account the length between the cables 77 and the curb rope 9.

FIG. 6 shows the shields at the wings 29, which are also arranged to prevent the formation of pockets in front of the wind 4, stretching the wings wide. It is also advantageous to arrange the extending connecting parts of the network at points 25, where the cables 7 / are attached to the I-ropes in order to avoid tangling the curb cables 9 with the cables 77, as schematically shown in FIG. 6, where the sinkers 30 are located around the rotating connecting parts 25. Thanks to these parts, arranged on the cables 77, which are strongly tensioned with the weight of the coil 4 and the sinker 30 and therefore very rigid, the ropes 9 can rotate freely to keep rubbing about bottom and circumvent the obstacle.

FIG. 7 shows an embodiment in which the cables / 7 are anchored in the middle of the fence at a common point 31, the inner edge 32 of the rod 4 is separated from the network 18 and provided with another grid, which

remains completely free, so that it accepts a form in which balance is maintained, which does not cause the loops to stretch.

FIG. The bridge is divided into two parts 4a and 4b, which have a common point 57, beyond which the cables 77.

With some bottom surfaces, it is more advantageous to replace the mesh with a rigid cross bar 33 (Fig. 9), for example, with a steel tube with rollers 34 of proper dimensions. The ends of this crossmember are attached to the cables 77 at points 26; if the traction parts of the ropes are separated from the curb ropes 9, or if these organs work together, then the cross member is attached to the ropes 8 (Fig. 1). Fitting this eliminates the possibility of tangling the ropes 9--77 and ensures proper operation if the ropes are tied to a sturdy part. Ropes 9 can be attached to the cross member using a ring or hook. The crossbar contributes to the lowering of the net into the water - the weight of the device gives the net greater stability. The rollers prevent sinking and make it easier to bypass the obstacles without putting them at risk.

A bagless seine is sometimes difficult to lower into water. Indeed, in ordinary seines with a bag of water, break into this funnel. facilitates the expansion of networks. In addition, when extracting nets from water, a bag from ordinary nets prevents wings from spreading out and, by that, allows that part of the fish that has not yet penetrated the mote to break free. At the same time, it can be seen that the bag is an inconvenience during fishing. To gain the benefit that the bag represents during fishing, you can adapt a safety tape or lining, the role of which is specifically to facilitate launching the seine into the water and removing it from the water, but which during fishing would not remove any of the advantages represented by the abolition of the bag and the pull of the rope directly with a pull rope. This safety tape, being completely independent of the network design, is not introduced in order to give it the correct shape, but may, therefore, break, and be caught fishing time.

To obtain these advantages, you can use a mesh lining (Fig. 9) or an old unnecessary network tied to the cables 7 / or to the ropes 9 with light ties or tearing slings, which could break or squeeze without any difficulty. STV. Do not disrupt network advancement. This mesh lining may have the dimensions of a regular bag or be only a transverse band that does not reach the pelt, in the latter case it should be taken into account that the permanent bodies that could be picked up by the rope 36 located in front of the lining 55 do not . Risks to get into the motnk, as they are again. fall to the bottom, leaving through the rear edge of the 37 tape.

To protect the coils 4 from wear, a plate 9 with holes is placed under the base 37--38 of the armature fittings (Fig. 10). „

According to another method, which protects 37-38 parts of the reinforcement located under water, loops of the network

or nettings tying it to the reinforcement are passed through the notches 40 (Fig. 11) .I
