Description
Technical Field
The invention belongs to the field of non-ferrous metal material products, and particularly relates to a full copper chain type connecting mechanism for a sheet type and box type device and equipment in ocean engineering and application thereof.
Background
The copper alloy material is widely applied to the field of ocean engineering due to the advantages of corrosion resistance, marine organism pollution inhibition, high conductivity, safety, reliability, practicability and the like, and mainly comprises the fields of seawater desalination, marine culture, ships, ocean oil gas development, coastal power stations, harbor buildings, ocean facilities and the like. Therefore, the design and development of the copper alloy and the connecting structural member thereof have great promoting effect on the structure and function integrated construction of the ocean engineering facility.
In the field of ocean engineering, copper alloy meshes and netting are one of the most widely used structures, such as offshore square and circular net cages, offshore spherical and polyhedral net cages, large-scale purse nets, aquaculture ships, antifouling nets, water inlet and outlet intercepting nets and the like. According to the manufacturing method, the copper alloy mesh and the netting can be divided into an oblique square woven mesh, a warp and weft woven mesh, a stretching mesh and a welding mesh. The copper alloy oblique square net is widely applied, a plurality of copper wires of the copper alloy oblique square net are parallelly penetrated and hung and are similar to a wavy structure, and a box body formed by the box body has the advantages of strong strain capacity, difficulty in breaking and damage, convenience in connection between the net and the net, axial rolling and folding of net sheets, convenience in transportation and the like under the condition of ocean currents. The copper alloy stretching net has the advantages of stable meshes, firm structure, non-contact moving abrasion and the like, and has the defects that the connection among net sheets is complex, the difficulty is high in the process of installing and constructing the box body, and the strain capacity of the rigid structure box body under the condition of ocean current is poor. The copper alloy mesh type structures of the copper alloy woven mesh and the copper alloy welded mesh have the same defects as those of the stretched mesh due to the rigid characteristics of the copper alloy woven mesh and the copper alloy welded mesh, and also have the defects of an oblique square mesh due to the movable or fragile state at the mesh joint point, so that the copper alloy mesh type structures of the two structures are less applied to ocean engineering. Therefore, the selection of the copper alloy net type will depend on the requirement of the field service environment of the ocean and the stress state of the equipment, and a multi-net type ocean engineering facility can also be formed. Such structures are not designed and selected independently of the connection, which becomes an important part of the assembly of the installation and is an important factor in the stability of the structure and the safe service.
In the actual engineering structures such as current copper alloy box with a net, purse seine, breed worker's ship, antifouling net, the connected mode who adopts between copper net and frame, copper net and copper net mainly has according to its structural circumstance: metal connection of the woven net-framework, nonmetal connection of the woven net-framework, connection between the woven net and the woven net, connection of the tensile net-nonmetal part, connection of the tensile net and the cabin body of the industrial ship and the like. (1) Metal connection of mesh-frame: the connection is mostly bundled by adopting double strands or similar metal wires, and the connection has the advantages of keeping the strength and the rigidity of the structure and effectively prolonging the service life, but has the defects of low bundling efficiency and high maintenance difficulty. (2) Non-metallic connection of mesh-grid-frame: the connection is mostly sewn by polyamide threads or bound by high-density polyethylene ropes, and has the advantages of high flexibility, abrasion resistance and wide material selection range, and has the defects of use of a large amount of non-copper structures and easy attachment of marine organisms. (3) Woven mesh-woven mesh connection: usually, the meshes of the side part are firstly threaded through a steel wire, and then two pieces of netting are directly connected by using a binding wire. The marine organism pollution prevention device has the advantages of material homogenization, effective marine organism pollution prevention, convenient operation and difficult disassembly and replacement if the marine organism pollution prevention device is damaged. (4) Connection of the tensile web to the non-metallic pieces: if a polyester canvas standard assembly part is prefabricated at first, then the copper alloy stretching net is connected with the polyester canvas standard module, and the quick assembly of the rigid-flexible combined copper alloy stretching net box body is realized; the advantage of this mode is that copper net, canvas and connecting piece all can be prepared into standard module in advance, realize quick installation, but because the corrosion resistance and the intensity of canvas and non-copper connecting piece all are less than the copper net, can lead to whole device destruction because of the junction is damaged in advance. (5) Connecting the stretching net with the cabin body of the industrial ship: the connection mode mainly aims at the cultivation ship, a ship body of a cultivation ship cabin is arranged below a water level line, rectangular windows are uniformly distributed on the ship body, and a prefabricated stretching net piece is arranged in the windows through fixing pieces. The mode has the advantages that the installation is convenient, the seawater throughput can be effectively improved under the condition of improving the mesh structure, and the stepped connection part has higher fatigue resistance, but the direct compression structure easily causes gap corrosion, so that the structure or parts fail in advance.
Meanwhile, the optimization design is also carried out on the basis of a typical engineering connection method, and the optimization design comprises the following steps:
the patent CN108293932A provides a copper alloy woven net connecting method, wherein two nylon rods are respectively connected to the vertical edges of two pieces of pre-connected copper alloy woven nets, and weft copper wires of the copper alloy woven nets are wound around the nylon rods for one circle and then twisted with the copper alloy woven nets for 3-5 circles; and then, bundling the two nylon rods at the vertical edges of the two copper alloy woven nets, namely, bundling the two nylon rods to align the meshes of the left and right copper alloy woven nets, bundling the two nylon rods by using a cotton rope, and bundling by using a line pressing method. The invention changes the connection of copper wires at the edge of the copper alloy braided net into the connection of nylon rods, and simultaneously uses a thread rope to carry out bundling by a thread pressing method.
The patent CN 108184722A provides a quick connecting mechanism and a method for a copper alloy woven mesh, the quick connecting mechanism comprises two copper alloy woven meshes, two edge connecting rods, an intermediate connecting rod and a plurality of double-hole connecting pieces, wherein the two edge connecting rods are respectively connected to the vertical edges of the two copper alloy woven meshes, and the intermediate connecting rod is connected between the two edge connecting rods through the plurality of double-hole connecting pieces; the connecting mechanism is connected by inserting the middle connecting rod, so that offshore installation and operation are facilitated.
A connection structure and a connection method for rigid-flexible combination of a copper alloy stretching net and a copper alloy stretching net are provided in the document 'rigid-flexible combination copper alloy stretching net netting net box performance and application research', the net box designed and manufactured by the method is composed of a high-density polyethylene double pipe with the circumference of 40m and the diameter of 250mm and a handrail pipe, and the net clothing is composed of an overwater anti-escape nylon net, a nylon bottom net and a side combined type copper alloy net. The combined netting is formed by splicing two layers of copper alloy stretching netting and soft connection, wherein each layer is provided with 44 copper alloy stretching net sheets; and 2 meshes, 2 layers of copper alloy stretching meshes, an upper layer of copper alloy stretching meshes and an anti-escape net, and a lower layer of copper alloy stretching meshes and a bottom net are connected by high-strength polyester canvas. Each subassembly of this structural net case is through standardization, modular production and concatenation in advance, is favorable to marine rapid Assembly and maintenance, and this net case can also avoid the tensile net piece of copper alloy to warp and the corner is lost the problem, but because the rerum natura difference of copper net and canvas is big, leads to the junction wearing and tearing easily, the canvas bears the weight big and fracture and the dirty scheduling problem that decreases of marine life of non-copper connecting piece.
In summary, although the connection structure described in the prior patents and documents can ensure the overall strength, stability and durability of the structure and the equipment, and avoid deformation and abrasion of copper wires caused by stress on the mesh sheet and the net cage, the above method has problems of marine organism pollution damage, partial advanced damage, reduced service life and the like due to the introduction of connection materials and structures such as nylon, canvas and the like, and is difficult to meet the requirements of marine engineering equipment. In the existing research and development and application processes of the connection structure of the ocean engineering equipment, most of work is concentrated on how to realize connection, and the research on the structure design such as material selection of the whole connection structure, corrosion resistance analysis of the whole structure and the like is lacked.
