Fishing device
FIELD OF THE INVENTION
The invention relates to a fishing device provided with a frame with near to a front side two sliding members which are spaced apart in a transverse direction and with at least one sehe pin direction located between the sliding members.
BACKGROUND OF THE INVENTION
Such a fishing device is known from WO2011 / 031075. This publication describes a fishing device for catching crustaceans, wherein a scooping member is arranged between two sliding shoes of a slide. The sled is pulled over the seabed behind a fishing vessel. The shellfish heated from the seabed by fingers of the scooping member are scooped separately from sand on a plateau and brought from there into a net floating free from the bottom behind the carriage.
The known fishing device is not suitable for fishing flatfish and for catching shrimp. Fish can also be damaged by contact with the fingers.
Such a fishing device is known from CN 202197678. This publication describes a fishing device that scoops fish and shellfish from the seabed with a plow.
Targeted fishing for sole and other flatfish with trawl nets currently uses three systems in N.W, European waters. The oldest way of fishing is the use of the beam trawl. The sumwing and the pulse trawl have also been added for a number of years. Flatfish hides in the bottom and therefore this fish must first be expelled from it before it can be caught. With the beam trawl and sumwing this is done with chains. The pulse core works with electrodes between which electrical pulses are generated. The fish crawls out of the bottom under the influence of these pulses.
In all three systems, one trawl net is moved across the bottom on both sides of the ship. A beam trawl consists of a tree (steel tube) with a shoe (sliding element) on either side, which keeps the tree at the correct height above the bottom. Between the slippers, low at the bottom, chains of various lengths are arranged with behind the ground string to which the bottom of the net opening is attached. The top of the net opening is on the tree.
At the sumwing, the tree has been replaced by a wing, not touching the ground, which keeps the top of the net at the right height keeping the bottom. The wing has the same length as the tree. The slippers have expired. The chains and ground tendon are pulled through the ends of the wing and sink to the seabed because of their weight and a considerably greater length than the wing. Both systems have a high drag resistance.
Turning the soil with chains causes damage to living organisms. The net of the pulse basket is kept open in the same way. The resistance, and therefore the fuel consumption, of a pulse trawl system is considerably lower due to the absence of chains. The soil disturbance has also been reduced.
The effect of the electrical pulses on the marine eco-system is still under investigation
A beam trawl provided with a water jet system for chasing flat fish out of the bottom is known from EP 0 908 094 in the name of the applicant.
It is an object of the invention to provide a fishing device with which flatfish and / or shrimp can be fished with minimal disturbance of the marine environment on the seabed. It is also an object of the invention to provide a fishing device in which contact with the marine animals and the damage caused thereby are minimized. It is a further object of the invention to provide a fishing device with which marine animals smaller than a predetermined size are caught.
Summary of the invention
To this end, a device according to the invention is characterized in that the sehep device is substantially closed and is located with a forward scoop side below the sliding surface and extends upwardly in a rearward direction from the forward scoop side to a delivery edge - preferably located above the sliding surface, a screen member arranged in the longitudinal direction behind the scooping device with a plurality of divergent conveyor elements for transporting marine animals located on the screen member to a net arranged behind the screen member and located above the sliding surface, the screen member being hingedly attached to the scooping device.
By using the fishing device according to the invention, the fish and organisms (benthos) living in and on the seabed do not come into contact with the scooping device or with heavy chains, a ground string or with the underside of the net and thus remain undamaged. Because the scooping device according to the invention is "substantially closed" - in contrast to the narrow and finger-scooping device according to WO2011 / 031075 -, it has such a width that a layer of soil of approximately 10 centimeters thick is shaved from the ground and lifted to the ground. sieve organ, whereby all marine flora and fauna remain untouched in and on this layer. On the screen member, which is, for example, in the form of a grid, the sand is separated from the sea organisms, whereby small marine animals are separated from large marine animals by falling through the grid from the screen member.
The advantage of the fishing device according to the invention over the beam beam with "jet alarm" known from EP 0 908 094 is that with the device according to the invention, tongue (which disappears into the bottom in the event of a shock) and shrimp can also be caught, while a low resistance is obtained over the bottom and minimal disturbance of the marine environment takes place.
The advantage of the fishing device according to the invention over the fishing device known from CN 202197678 is that with the device according to the invention * through the flexible attachment of the sieve member to the scooping device, a flexible construction is obtained which can easily follow irregularities in the bottom .
In an embodiment of a fishing device according to the invention, the scooping member is attached to the frame via a length-adjustable cable, whereby the scooping member is pulled through the frame during operation.
Due to the flexible attachment of the scooping device to the frame via the cable, when passing over unevennesses in the bottom, such as sand dunes and / or stones, the scooping member can easily move upwards relative to the frame to pass over the unevenness.
The depth at which the scooping device penetrates the soil can be adjusted by adjusting the length of the cable attachment.
Resilient sorting knives can be arranged behind the screen member. With these sorting knives, smaller fish can be left in the sea and larger fish can be led through a net surrounded by nets to the nets pulled behind the frame.
In one embodiment, a second gliding hen is arranged behind the screening member. When the ground is being raised, the second sliding shoe prevents skewed pockets from the frame in the loosened soil.
In a further embodiment of a fishing device according to the invention, a number of tunnels extend along the frame and are each connected to a separate safety net at the rear of the frame.
The use of several relatively small safety nets results in a lower resistance of the fishing device in comparison with a single safety net with a larger size.
The invention also relates to a sanitary set of a fishing device with two neck lines at width ends of the frame and a vessel provided with a drum extending at a distance above the deck over at least the width of the frame in the longitudinal direction of the vessel , for which drum the story lines of the fish mricliting can be wound.
When the fishing device is brought on board, it is suspended vertically from a boom that extends transversely to the ship. By wrapping the line line around the drum, the frame and the nets attached thereto are brought in from the boom with the width of the fishing device parallel to the longitudinal direction of the ship.
The invention further relates to a vessel provided with at least one boom for attachment to a fishing device and with at least one drum with a length of at least two meters, which drum extends in a longitudinal direction of the ship and at a distance of at least two meters above the deck.

Detailed description of the invention
FIG. 1 shows a fishing device 1 with a frame 2, which is pulled on a cable 3 via a fishing vessel over the seabed 5. A scooping member 7 is attached to the frame 2 on a front side 6.
The frame 2 has two sliding members or side carriers 8, 9 (see also Fig. 2) which slide over the seabed 5. The side supports 8, 9 are kept at the right distance from each other by round and square tubes. These tubes are interconnected by thinner tubes and angular steel profile in order to obtain a strong and rigid construction.
Three scooping members or planers 7,12,13 are attached to the frame 2 (see also Fig. 3 and Fig. 4). The scooping members 7, 12, 13 are closed and relatively wide, so that scooped-up sand cannot pass through the scooping members in downward direction. The scooping members 7, 12, 13 run obliquely upwards from a forward sezp side 15 back to release edge 16. From the release edge 16, scooped-up seabed with sea animals therein falls on a screen member 17 located behind the scooping member 7, which via a universal hinge 18 scooping member is connected and thereby pulled. The layer of soil that is shaved by the scooping members 7, 12, 13 is raised and falls on and between grid bars of the screen member 17.
The openings at the top and sides of the frame 2 are covered with a network 20. The fish of most flatfish species flee upwards and are prevented therein by forcing nets 22, one per scooping member 7,12,13. The forcing net 22 is at the front rigidly attached to tube 23 and by means of a stretchable rubber tendon 24 on the scooping member 7.
Smaller fish and benthos will be carried by the downward movement of soil and water at the location of the grid 19, 21 (see Fig. 4) of the strainer 17 and end up between the grid bars. Larger fish remains on the grid bars.
A row of fingers or knives 26 then separates the smaller and larger fish. The blades 26 are attached to pipe 27 and are provided with a rubber damper 28 to prevent damage to the blades by stones on the seabed. Smaller fish remains in the sea and larger fish is transported via four tunnels 30-33 to four nets 35,36,37 and 38.
The fishing gear is pulled by a fishing line 3 connected to a block in the top of the boom 40, 40 "of the fishing vessel 41 (see Fig. 5). Via a sprout 42 the traction force is transferred to two pull point adjustments 43,44 which are bolted to the front of the fishing gear 1. The purpose of the pull gear adjustment is to make the pull point bow on the fishing gear dependent on the angle of the fishing line 3.
In some places in the sea the bottom 5 is not flat, but there are rocks or underwater dunes. If the fishing gear is pulled against a slope, the angle of the fishing line 3 will become smaller, starting from a slope it will become larger. The pressure from the bottom on the fishing gear must engage approximately half the length of the fishing gear. If the pressure point comes forward too much at a smaller angle and a fixed draw point, there is a chance that the front of the gear will dig itself in. The draw point adjustment is formed by a fork 45 with two steel rollers 46, 47 moving along a curved track 51.
The scooping members 7, 12, 13 are each pulled by double, endless steel wires 48 arranged on their sides. These steel wires 48 are guided over the tube 23 and are connected to an adjusting device 49. With this, the thickness of the shaved layer of soil can be adjusted.
A chain 50 is attached to either side of each scooping member 7, 12, 13. The purpose of this chain 50 is to allow the various components to be prevented during the overtaking and expansion of the fishing gear present at that moment in the water column between the water surface and the seabed from being damaged due to "beating" of the scooping member.
Large stones pass on the underside of the scooping member 7, the grid of screening member 17 and the resilient knife 26 and remain on the seabed. The scooping member will be lifted and the side plates 52 will not touch the stop 53 and the pipe 54. The fishing gear 1 then comes to the front of the ground.
Upon contact with a knife 26, the rear of the fishing gear 1 is pushed upwards. Small stones will eventually end up in the net 35 via the top of the scooping member 7, the screen of the screening member 17, the knife 26 and the tunnel 30. In the bottom of each net 35-38 there is a portion of two overlapping pieces of network in the longitudinal direction, which are not connected to each other. The tensile forces in the net in the towing direction ensure that the two sections remain against each other without significant opening between them. Due to their weight, the stones that are dropped will push open the overlap and get out of the net. A fish does not have the weight to do this, passes the overlap and enters the pit 55 (see Fig. 2).
Screen boards 56, 56 "arranged on the top of the net must prevent the net from touching the bottom due to the generated force.
The tensile force of the scooping member 7 on the screen member 17 is transmitted by means of a flexible connection 18. A shaft 58 is attached to the scooping member 7. There is a bracket on each gridable van that grips around the axis. The radius of the bracket is greater than that of the axis. To keep the distance between the grating bars constant, rubber fillings are provided between the brackets.
The soil is broken and filled up when falling through the screen of the screen member. A consequence of this is that the carrying capacity of the side carriers 8, 9 decreases at the rear of the gear and the gear can thereby sink slightly. The distance between the bottom of the blades 26 then becomes smaller. Whether or not to sink away depends on the sport ground. In case one or more carriages 59 can then be mounted between the side carriers which can overcome this disadvantage.
For targeted shrimp fishing, coercive nephew 22 is canceled. Due to agitation of the bottom, shrimp jump up. Captured fish can be left in the sea as much as possible by using seheidingspanels in het, a well-known technique.
A yiskotter 41 according to the invention as shown in FIG. 5 and FIG. 6, is equipped with two booms 40, 40 ". (l) the fishing gears 1,1 "are connected via fishing lines" 60 to a fishing winch located in a casing 61.
The booms are horizontal while fishing. On the port side of Fig. 6, the fishing gear 1 is drawn in the position for emptying the nets. On the starboard side, the situation when gear 1 "is on deck when there is no fishing. The side view in Fig. 5 shows only the port gear.
In order to empty the nets, the fishing lines 60 are wound up to such an extent that the fishing gear hangs vertically, just above the water. l) The ends of the shark lines 62,63 can now be caught with a hook and the air-filled bladders 66 removed. By pulling the shark lines by hand, the fishing gear can be rotated 90 degrees so that they are parallel to the longitudinal direction of ship 41 and parallel to the bulwark 64.
By having the booms 40,40 "lifted", the harnesses 1, 1 "came closer to the ship. The story lines 62, 63 are wound on the drums 67, 68 and as a result, the harnesses hit the fenders 69.
A steel wire 70 is stretched between the two side supports at the top of the frame 2 (see Fig. 4). Four silage ropes 71-74 are attached to this steel wire 70. Hook 75 can be reached by hand and can be disconnected from pit rope 74.
The four pit ropes can now be connected to a jumper wire 80 already present on the cutter. The rear parts of the nets, the pits 55, are then hoisted on board. Distance lines 81 of different lengths between the pits and a fixed point 82 cause the pits to hang in line under the jomper block 83 above the cistern 84.
