Description

In the proposed device for checking the cleanliness of the fairway, a sweep band, articulated lots, suspended from lot-liners, enveloping blocks on the rods, pivotally connected to the side of the vessel, is provided with a discontinuous part connected with a stick; at the moment of the rupture of the sweep line, in contact with an obstacle, the pole stands on the surface of the water.

In FIG. 1 is a rear view of the fairway inspection device; FIG. 2 - its top view; FIG. 3 is a side view of a lot of fish; FIG. 4- type landmarks.

The hard part of the device consists of two rods 7, one on each side, with the corresponding rigging, fastened at the sides of the vessel with the help of a chain lock, which is pawned. on the deck (at the bead) there are two rods of bullet heel, each of which consists of two gas tubes, screwed together with a threaded coupling 5. A nipple is inserted into the tubes at the junction for rigidity.

On the noka and on the middle of each rod, the bow is set, on the noque with four ears 4, and in the middle with three ears 5. The upper ears of the bows for srutetose 6, lateral for bras 7 and chipmunks 6, and in the fourth lower ear on. A small block 9 is suspended at this time for laying lot-ling lot-fish. The heel of each rod in the eye on the deck has the same JO block for the same purpose.

The rigging of the rods is made up of two pairs of brasses 7 and chipmunks 8, with which you can optionally dump the rods perpendicularly to the board and fill the stern of the ship, and two squirrets 6 with kooshes 7 /. Placing 77 talas with a pendant 75 in thimbles 77, it is possible, if desired, to raise or lower the rod and to keep it at a desired height during the production of trawling.

Through the small blocks 9 and JO, suspended from the rods, from the J4 views installed in the stern of the vessel, the steel lot-line 75 is passed through to the fathoms (flag) and feet (copper wire marks).

Lot-75 ends with lot-fish 76, connected to it with a small chain lock, placed in a couch 75a, which is located on the chassis, the end of a lot-lin, and an average hole in the upper transfer lot (Fig. 3). Trail strip 77 consists of a steel string inserted at its ends at the ends of the lot-lin at the ends 15a. The width of the sweep strip is approximately equal to the length of the rigid part. Approximately in the middle of the sweep strip, the rupture part 18 is inserted. The sweep strip (7) is freely slid by the ring of a small cat (I) connected by a string 20 with a small stick 2 /, which comes apart at the moment of rupture of the sweep strip when it touches the obstacle.

Landmark 21 (Fig. 4) is made of a dry reed rod with a crown drum set on one third of its bottom. At the bottom of the pole there is a weight to hold it on top of the water spout in an upright position and a small ring for inserting the string that connects the pole with the cat. The length of the twine should be somewhat greater depths in the area of trawling.

For the production of verification of fairness, the channels 14 are set in place and bolted to the deck. Rods / with fixed, in place blocks I. lay along the deck with nocks on the stern of the ship with the expectation that their heels fall to frames 2, and a butt in. The rod of the rod is connected to the eye with a chain lock, and the small blocks, W are fastened into place.

The brasses 7 are carried along the board to the bow of the vessel and are passed through the bales 22 and fastened by the bows 23. The chipmunks 8 are fastened on the stern ears 24. Tali / 2 are laid in the thimble // sprite. b and the slack of the spreets is chosen by them, after which the running gears are attached to the shrouds (or where it is more convenient).

.rioT-lines are connected to a lot of fish, and ends of the main strip / 7 are inserted into the bows of the fSa. A ring of a small cat / 5 is put on one of the ends of the trawl strip and both ends are connected by a tearing part / 8. Then a lot of fish is placed in nests 25 near the views, and the trawl strip stretches along the vessel (according to its abilities). The required quantity of lot-lin is dialed from f4 viewpoints and it is put into blocks 9 and 10 suspended on rods, after which the lot-lin slack is picked up by the views. This is where the installation of the trawl on the ship ends.

The lot-fish will come to the place of work with the help of stoppers, gently lower the stern into the water, along with the sweeping strip, while gradually picking up the slack of the lot-ling views, until the lot-fish are under the nozzles of the rods. The rods fall off perpendicularly to the sides, and the lotrats of the grasses are 1-fold to the desired depth. The depth is counted by marks on a lot line directly at the surface of the water.

When trawling a lot of fish go the same way, ka, to and when measuring and carry out the trawling belt. When the engine is automatically suspended, the landmark floats vertically on the surface of the water, during the course of the vessel, the trailing strip is not, it does not go into the water and goes along the line of least resistance. In contact with the obstacle, the obstacle has a discontinuous part of it, designed only for co, photisation of water, tears; the small cat slides off the sweep line and reverts, and the pole appears and shows the place of danger. In addition to the landmarks, the moment when the ladder is touched to the obstacle can also be noted if you follow the lottery at the place of its passage into the water, because at the moment of touching the obstacle, lot-line makes a distinctive stress and makes a specific sound that is different from the ordinary jingle sound. with the passage of the trawl in free water. It is not excluded the possibility of catching an obstacle for a lot-fish directly, and then the lot-fish begins to lag and make noise; in order not to lose it, which is very likely, if it is slaughtered between stones, it is necessary to immediately poison the lot-line and back up or at least stop the motor. Getting close to the lot fish back. By moving or picking up a lot-ling view, when the motor is locked, you can pull out the lot-fish and, after determining the place of danger, continue trawling. In the first case, the discontinuous part of the sweep rvet band; to continue trawling, it is sufficient to select its ends on board and start a new breaking section and a pole.

To change the depth of trawling, it is enough to pick up or poison a lot-line with views. If necessary, you can instantly pick up the main sweep strip close under the hull. During trawling, lots must always be on the views. At the end of the trawling, the lot fish are picked up by the views to the surface; shtangizavali on the stern; the lot of fish, along with the trawl strip, are selected by the catch hooks and placed in their nests 25, and the trawl strip stretches along the deck of the vessel and is smeared with lard to avoid rust.

The subject matter of the invention.

A device for checking the cleanliness of the fairway, characterized by the use of lifting, hingedly attached shipboard rods e, carrying blocks 9, 10 at the ends with lot lines 75 and lotryba 16 at the end of the line, which lots are connected between themselves by a sweep 17 with a breakaway part 18 between them, connected with a pole 21, intended to float to the surface of the water at the moment of rupture of the sweeping strip when it comes into contact with an obstacle.
