Description

Underwater purse seine facility for fishing

Technical Field

The utility model relates to a salvage technical field, specifically speaking, the utility model relates to a salvage under water purse seine facility.

Background

The condition that a large amount of goods and materials in a cabin of a ship difficult to overturn can be lost frequently during salvage operation, so that the situation that goods in the cabin drift away from a sunken ship position to cause secondary accidents and the like needs to be effectively blocked around the difficult ship, and the goods and materials in the difficult ship are surrounded in a relatively fixed area. Because the water flow and the surge bring technical difficulty to the underwater fixing purse seine, at present, no related facility and equipment matched with the prior art can meet the blocking requirement of the purse seine in the underwater fixing area.

Disclosure of Invention

The utility model aims to solve the technical problem that a purse seine facility that can use under water is provided, and its main part is single net piece, and the purse seine region can be put, form after enclosing by a plurality of net piece combinations, and the net piece can be hung by operation boats and ships and put to under water, mainly can be used to the shallow water region and prevents that the object from drifting.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a salvage with purse seine facility under water, includes net piece frame, horizontal vaulting pole and wire net, horizontal vaulting pole transversely sets up on two net piece frames, and the wire net is hung on horizontal vaulting pole and net piece frame, the net piece frame includes concrete placement steel box, base bracing, net piece support and net piece bracing, the both sides limit of concrete placement steel box sets up the base bracing, and the middle part of concrete placement steel box sets up the net piece support, and net piece support both sides limit is the A style of calligraphy and sets up the net piece bracing.

Preferably, the anti-skid nails are uniformly distributed at the bottom of the base inclined strut and the bottom of the concrete pouring steel box.

Preferably, hoisting eye plates are arranged on the upper portions of the two side faces of the concrete pouring steel box.

Preferably, the mesh frame, the transverse stay bars and the steel wire meshes form a mesh, and a plurality of meshes are combined together to form the seine facility.

Preferably, the bottom of the mesh is provided with a heavy chain.

Adopt the technical scheme of the utility model, can obtain following beneficial effect:

the utility model discloses a salvage with purse seine facility under water, the construction ship can directly hang single net piece and put under water and carry out the unhook by underwater robot or diver, can overlap the multiunit net piece as required and put and enclose into closed area, will inject sunken ship, the debris in the area and enclose in order to have the unknown object to float out, influence the ship and the salvage operation of surface of water navigation.

The contents of the description and the references in the drawings are briefly described as follows:

FIG. 1 is a schematic view of a mesh frame;

FIG. 2 is a schematic structural view of a single mesh formed by combining two mesh frames;

fig. 3 is a structural diagram of a single mesh.

The labels in the above figures are: 1. pouring a steel box by concrete; 2. a base diagonal brace; 3. a mesh support; 4. a mesh diagonal bracing; 5. hoisting the eye plate; 6. anti-skid nails; 7. a bolt; 8. a transverse strut; 9. a heavy chain; 10. and (5) steel wire meshes.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.

As shown in fig. 1, 2 and 3, the underwater purse seine facility for fishing comprises net piece frames, transverse support rods 8 and a steel wire mesh 10, wherein the transverse support rods 8 are transversely arranged on the two net piece frames, the net piece frames are clamped between the two transverse support rods 8, and the steel wire mesh 10 is fixed on the transverse support rods 8 and the net piece frames through bolts 7.

The net piece frame includes concrete placement steel case 1, base bracing 2, net piece support 3 and net piece bracing 4, the both sides limit of concrete placement steel case 1 sets up base bracing 4, the fixed net piece support 3 in concrete placement steel case 1's middle part, 3 both sides limits of net piece support are the A style of calligraphy and set up net piece bracing 4, the top at net piece support 3 is fixed to the one end of net piece bracing 4, the other end is fixed in concrete placement steel case 1, net piece bracing 4 can form the support to net piece support 3, prevent that net piece support 3 from appearing crooked.

As shown in figure 1, the anti-slip nails 6 are uniformly distributed at the bottoms of the base inclined strut 2 and the concrete pouring steel box 1, the anti-slip nails 6 can prevent the net sheets from sliding on the seabed, the hoisting eye plates 5 are arranged on the upper portions of the two side faces of the concrete pouring steel box 1, and the concrete pouring steel box 1 is convenient to hoist due to the arrangement of the hoisting eye plates 5.

As shown in fig. 3, a net piece is composed of a net piece frame, a transverse stay bar 8 and a steel wire net 10, a plurality of net pieces are combined together to form a purse seine facility, a counterweight chain 9 is arranged at the bottom of the net piece, and the counterweight chain 9 plays a role of counterweight when the net piece is lowered underwater, so that the net piece is conveniently lowered.

When the construction ship is used, the construction ship can directly hoist the net sheets to the underwater and unhook the net sheets by an underwater robot or a diver, the net sheets are connected by bolts 7, a plurality of groups of net sheets can be overlapped and arranged to form a closed area as required, sunken ships and wreckages in the closed area are surrounded to prevent unknown objects from drifting out, and ship and salvage operation of water surface navigation are influenced.

This single net piece is steel construction and wire net, and simple manufacture can adopt the modularization preparation, improves production efficiency, can the multi-disc combination put, suitable use on a large scale. The height of the purse seine and the size of the meshes can be adjusted as required, the influence of water flow is reduced while the efficiency of the fence is improved, and the purse seine facility can be recycled and has small influence on the environment.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
