Description

Fish driving device

Technical Field

The utility model belongs to the technical field of aquaculture, in particular to catch up with fish device.

Background

For years, the resource advantages of Lincang city are fully exerted, the development concept of 'ecological fishery, efficient fishery, brand fishery and sightseeing fishery' is adhered to around the target of Lincang creating important plateau special freshwater fishery production bases in Yunnan and even nationwide, and the ecological fishery development of the Lancang river power station reservoir area is promoted. The small bay reservoir area belongs to an adjustable hydropower station, is a high mountain gorge lake, is deep and long, has large reservoir capacity, is complex in underwater landform, surges in undercurrent, is staggered with cliffs, and stands in a tree stump forest. In the combined large fishing theory of blocking, stabbing, driving and opening, under the premise of finding out the position of fish school, a fence net is used for surrounding, a lower opening net is arranged, an 'splayed' door is arranged between the fence net and the opening net, then the fishnet is used for driving, wherein the fish is most difficult to be driven; because the water is too deep and the underwater landform is complex, the traditional barbed net cannot fall to the bottom of a river, and a plurality of fish schools escape from the net bottom. If the net is lowered to the deepest, the netting gear is often torn by rocks and stakes, or the net has to be actively cut, causing fish to escape. Therefore, it is necessary to design a fish catching device which can be deep enough to catch the fish, prevent the fish from escaping from the bottom of the net, and prevent the fish from being caught by rocks and stumps.

Disclosure of Invention

In order to overcome the problems in the background technology, the utility model provides a barbed wire bottom which is scratched on the complex underwater ground by scratching teeth, so as to avoid the barbed wire being hung by rocks and stumps and torn or the net sheet has to be actively cut off, thus leading the fish school to run away; the rowing teeth make sound in the process of dragging and rowing on the ground and stir water to play a role in driving fish schools.

In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a catch up with fish device mainly includes acanthopore, float, draws tooth, safety rope, stay cord, string rope, the float on be equipped with acanthopore, evenly weave the safety rope that has the longitude and latitude direction on the acanthopore net surface, evenly tie through hanging the rope on the safety rope of acanthopore bottom and draw the tooth, acanthopore top both ends are tied and are had the stay cord, the buoyancy of float be less than the gravity of drawing the tooth.

The utility model discloses a wire netting machine, including the thorn net, draw the tooth and be equipped with the ear knot for the cone structure, draw the top of tooth, the ear knot is smooth circular cross section ear knot, draw the tooth through ear knot by even system on the horizontal rope of thorn net bottom.

The floater is a pneumatic tyre or an inflatable bag.

The utility model has the advantages that:

the utility model adopts the cutting teeth to cut on the complex ground under water, thereby avoiding the barbed wire net from being hung by rocks and stumps and torn or having to actively cut off the net sheet, so that the fish school escapes; the rowing teeth make sound and stir water to repel fish during the dragging and rowing process on the ground; the buoyancy of the floater is smaller than the gravity of the rowing teeth, so that the bottom of the rowing teeth is ensured to be in contact with the ground, the floater is suspended in water, when the ground fluctuates, the fish catching device automatically floats upwards or sinks, the rowing teeth are ensured to be in contact with the ground, and fish schools are prevented from escaping.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

The utility model discloses a catch up with fish device, a catch up with fish device mainly include gill net 1, float 2, draw tooth 3, safety rope 4, stay cord 5, hang rope 6. The top of the barbed wire net 1 is provided with a floater 2, the floater 2 is a pneumatic tire, the inflation and deflation are convenient, and the suspension effect is good; the barbed wire 1 is uniformly provided with safety ropes 4, the safety ropes 4 comprise longitudinal ropes 41 and transverse ropes 42, and the longitudinal ropes 41 and the transverse ropes 42 are uniformly woven on the wire surface of the barbed wire 1; the transverse rope 42 at the bottom of the barbed net 1 is connected with the hanging rope 6, and the gravity and the pulling force of the scratching teeth 3 are mainly born by the safety rope 4 and the hanging rope 6 in the working process, so that the barbed net is prevented from being torn due to overlarge stress; the scratching tooth 3 is of a cone structure, the top of the scratching tooth 3 is provided with an ear buckle 31, the ear buckle 31 is a smooth round-section ear buckle, and the scratching tooth 3 is uniformly tied on a transverse rope 42 at the bottom of the barbed wire net 1 through the ear buckle 31 by a hanging rope 6; as shown in fig. 3, the scratching tooth 3 is of a cone structure, which is beneficial to scratching on a complex ground, the ear button 31 is a smooth round-section ear button, which can reduce the abrasion of the ear button 31 on the hanging rope 6 in the working process and is beneficial to improving the service life, the scratching tooth makes a sound and stirs water when scratching on the complex ground underwater, which plays a role of driving fish schools and avoiding the escape of the fish schools from the net bottom, when the scratching tooth 3 encounters the rock 8 and the stump 9, the scratching tooth 3 correspondingly scratches in states of 31 and 33 in fig. 3 under the pulling of the pulling rope 5, so that the pricking net is prevented from being hung by the rock 8 and the stump 9 to be torn or the net sheet has to be actively cut off, which causes the escape of the fish schools; when meeting the ditch hollow 7, the rowing teeth 3 are in a vertical 32 state, so that the fish is prevented from escaping; the buoyancy of the floater 2 is smaller than the gravity of the rowing teeth 3, so that the bottom of the rowing teeth 3 is ensured to be in contact with the ground, the floater 2 is suspended in water, when the ground fluctuates, the fish catching device automatically floats upwards or sinks, the rowing teeth 3 are ensured to be in contact with the ground, and fish schools are prevented from escaping.

The working process is as follows:

after the purse net, the fence net and the net are ready, the barbed net is connected with the fishing boat through the pull rope 5, after the floater 2 is inflated, the barbed net is put into water along the purse net, when the scratching teeth 3 fall on the ground, the scratching teeth 3 drop the inflated floater 2 to the ground, the barbed net is submerged in the water and is in a suspension state, the barbed net 1 is pulled open by the buoyancy of the floater 2 and the gravity of the scratching teeth 4 to be in a vertical state, and the fishing boat pulls the fish catching device to move towards the net opening direction to catch fish herds to escape forwards; the rowing teeth 3 make sound and stir water to play a role in driving fish shoals in the process of dragging and rowing the ground; and (5) after the fish catching is finished, collecting the net to finish the fish catching work.

The utility model adopts the scraping teeth 3 to drag and scrape on the complex underwater ground, thereby avoiding the barbed wire net 1 from being torn by the rocks 8 and the stumps 9, or having to actively cut off the net sheets to cause the fish to run away; the rowing teeth 3 make sound and stir water to play a role in driving fish shoals in the process of dragging and rowing the ground; the buoyancy of the floater 2 is smaller than the gravity of the rowing teeth 3, so that the bottom of the rowing teeth 3 is ensured to be in contact with the ground, the floater 2 is suspended in water, when the ground fluctuates, the fish catching device automatically floats upwards or sinks, the rowing teeth 3 are ensured to be in contact with the ground, and fish schools are prevented from escaping.
