Abstract

The utility model relates to a float trawl net which belongs to a hollow sphere which is machined from rigid plastic. The utility model is characterized in that four ear rings are arranged on the sphere, and the four ear rings are arranged on same tangent plane of the sphere symmetrically and pairwise. The utility model has the advantages of simple structure and convenient tie application, the resistance and cost of the trawl net can not be increased, and the float trawl net is particularly suitable for sparse meshes of trawl net.

Description

Float trawlnet

The utility model relates to a kind of fishing net annex, specifically a kind of Float trawlnet.

We know that float is the necessary parts of trawlnet netting gear, and at present, Float trawlnet generally is by rigid plastics processing, is hollow sphere, has two earrings, so that tie up knot with headline.Development along with the trawlnet netting gear, size of mesh also increasing gradually, has reached tens meters, tens meters, do like this and can reduce trawl resistance greatly, improve trawlnet speed, it is long-pending that the sea is swept in increase, improves catch, but above-mentioned Float trawlnet is unsuitable for dredging the order trawlnet, easily " cover is floating ", promptly the Lecideales footmuff is hung float and is tangled, and causes and tears the online story event, particularly the big-holed net clothing tears the back and mends the net difficulty, both increase crewman's labour intensity, reduced the activity duration again, seriously influenced work production, and solve " cover floating " relatively effective method be to adopt two headlines, promptly add an additional guiding principle in the float outer, above-mentioned float is wrapped with the small-eyed net clothing, clone is to additional guiding principle, doing shortcoming like this is to have wasted material, increased trawl resistance, and, easily come off because the ligation of small-eyed net etting is not really firm.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, and it is convenient to tie up knot, does not increase the novel Float trawlnet of trawl resistance and cost.

For achieving the above object, a kind of Float trawlnet, it is characterized in that for the hollow sphere of rigid plastics processing spheroid is provided with four earrings, they are symmetrically distributed on the same tangent plane of spheroid in twos.Four earrings of the utility model are pricked knot in twos on the headline and additional guiding principle of trawlnet, have solved " cover is floating " phenomenon of trawlnet well.It is simple in structure, the bundle knot is convenient, can not increase trawl resistance and cost.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model user mode schematic diagram.

As can be seen from Figure 1, a kind of Float trawlnet, it is a hollow sphere, spheroid 1 is made by rigid plastics.The spheroid outside is processed with four earrings 2, and they are symmetrically distributed on the same tangent plane.During use, as shown in Figure 2, two earrings are pricked knot on Float trawlnet guiding principle 3, and two earrings are pricked knot on additional guiding principle 4 in addition, can save raw material, and can not increase trawl resistance without small-eyed net clothing wrapping float like this.It is convenient to tie up knot, has prevented etting " cover is floating " and damaged.

The utility model is simple in structure, and is easy to use, can improve the catch of trawlnet greatly, is very suitable for dredging the order trawlnet and uses.

Claims

1, a kind of Float trawlnet, it is characterized in that for the hollow sphere of rigid plastics processing spheroid is provided with four earrings, they are symmetrically distributed on the same tangent plane of spheroid in twos.
