Abstract
The invention discloses a wheel type truss rod dragging net. The wheel type truss rod dragging net is characterized by comprising a truss rod (1), wheels (2) are supported at the two ends of the truss rod (1) respectively in a rotary mode, a plurality of cross ropes (3) are evenly distributed in the axial direction of the truss rod (1), and all the cross ropes (3) are connected with steel warps (5) through connecting rings (4). A plurality of hanging chains (6) are evenly distributed on the truss rod (1), the other ends of the hanging chains (6) are connected with ground ropes (7), the truss rod (1) and the ground ropes (7) are connected with the upper opening edge and the lower opening edge of the dragging net (8) respectively, and a net bag (9) is arranged at the tail end of the dragging net (8). The wheel type truss rod dragging net is simple in structure and exquisite in design, the height of the net opening is not limited by the dragging speed and the wheel type truss rod dragging net does not damage a seabed severely.
Description
Technical field
The present invention relates to a kind of trawlnet, particularly a kind of wheeled boom trawlnet.
Background technology
Traditional boom trawlnet is mainly used in fishing for the marine organisms such as fish, shrimp crab class and shellfish that perch at coastal waters bottom, and its operating water depth is generally less than 20 m.Owing to perching a large amount of juvenile fish and juvenile prawn in offshore sea waters, the catches specification that therefore traditional boom trawlnet is caught is less, and economic worth is lower, but the destruction that fishery resources are caused is larger.In the middle of operation process, height of net opening is subject to towing speed restriction, if towing speed is too high, traditional boom trawlnet can be aweigh, and towing speed is too low, and boom can contact seabed, and network interface is difficult to open, and catches all defy capture in above two kinds of situations.Ground rope due to traditional boom trawlnet is iron chains simultaneously, therefore in towing process, can cause serious destruction to sea bed.In sum, need now a kind of novel boom trawlnet that can address the above problem.
Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, can under any condition, keep network interface to open, and height of net opening is not limited by towing speed, and the wheeled boom trawlnet that can not do great damage to sea bed.
Technical solution of the present invention is: a kind of wheeled boom trawlnet, it is characterized in that: described boom trawlnet comprises boom 1, at the two ends of boom 1, rotational support has roller 2 respectively, boom 1 axially on be evenly distributed with a plurality of fork guiding principles 3, all fork guiding principles 3 all by connecting ring 4 with drag guiding principle 5 and be connected, on boom 1, be also evenly distributed with a plurality of chain slings 6, the other end of all chain slings 6 is all connected with ground rope 7, boom 1 is connected with end opening edge with the upper brim edge of trawlnet 8 respectively with ground rope 7, at the tail end of trawlnet 8, is also provided with net capsule 9.
Described fork guiding principle 3 is divided into 11 two kinds of the little fork guiding principles that are arranged on the large fork guiding principle 10 of boom 1 both sides and are arranged on boom 1 middle part, the end of large fork guiding principle 10 is directly connected with connecting ring 4, the end of little fork guiding principle 11 is connected with little connecting ring 12, and little connecting ring 12 is connected with connecting ring 4 by a fork guiding principle 3.
Described trawlnet 8 is symmetrically arranged two, and its opening is all connected with ground rope 7 with boom 1.
On described ground rope 7, there are a plurality of rubber rolls and the iron sinker that are arranged alternately.
Compared with the existing technology, tool has the following advantages in the present invention:
Because the boom two ends of the wheeled boom trawlnet of this kind of version are provided with the roller that proportion is greater than seawater; thereby can guarantee boom and seabed maintenance fixed range in the process of fishing for; ground rope is positioned at seabed all the time; therefore this kind of boom trawlnet has darker operating water depth; greatly increased working area; when having protected coastal water fishery resource, catches specification increases, and economic benefit also increases thereupon.And its network interface can remain open configuration in operation process, can effectively catch catches.Adopt wheeled ground rope simultaneously, also greatly reduce the destructiveness to sea bed.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing explanation the specific embodiment of the present invention.As shown in Figure 1: a kind of wheeled boom trawlnet, it comprises boom 1, at the both ends of boom 1, rotational support has the roller 2 of irony or other metal materials respectively, boom 1 axially on be evenly distributed with a plurality of fork guiding principles 3, fork guiding principle 3 is divided into 11 two kinds of large fork guiding principle 10 and little fork guiding principles, wherein large fork guiding principle 10 is arranged on the both sides of boom 1 symmetrically, little fork guiding principle 11 is arranged on the middle part of boom 1, the end of all little fork guiding principles 11 is all connected with little connecting ring 12, the end of all large fork guiding principles 10 is all connected with connecting ring 4, connecting ring 4 is connected with little connecting ring 12 by a fork guiding principle 3, connecting ring 4 is connected with the guiding principle 5 that drags being arranged on towboat again simultaneously, on boom 1, be also evenly distributed with a plurality of chain slings 6, the other end of all chain slings 6 is all connected with ground rope 7, what on ground rope 7, replace is provided with a plurality of rubber rolls and iron sinker, ground rope 7 is rolling friction when with boom 1 motion and between seabed like this, can seabed not caused largely and be destroyed, boom 1 is connected with end opening edge with the upper brim edge of trawlnet 8 respectively with ground rope 7, and is also provided with net capsule 9 at the tail end of trawlnet 8.
The course of work of the wheeled boom trawlnet of the embodiment of the present invention is as follows: trawler pulls boom 1 by draging guiding principle 5, the roller 2 at boom 1 two ends is rolled in seabed, because the proportion of ground rope 7 is greater than seawater, therefore ground rope 7 contacts seabed all the time, allow the network interface of trawlnet 8 open, the marine marine products such as fishes and shrimps enter in trawlnet 8, realize trawl fishing.Due to the existence of roller 2, can allow boom 1 keep fixed range, network interface to remain and open with seabed all the time, while therefore fishing for, height of net opening is not subject to the restriction of towing speed.
