Abstract
The invention discloses a marine tuck net-shaped sacrificial anode which comprises a tuck net-shaped matrix, wherein the tuck net-shaped matrix is formed by a plurality of wire ropes via connection; and a plurality of sacrificial anode bodies are arranged on the tuck net-shaped matrix. Through the tuck net-shaped sacrificial anode provided by the invention, a traditional large national-standard anode is made into a plurality of small tuck nets, so that the anode water contact resistance can be decreased by increasing the anode water contact area as large as possible and the anode generation current and the anode efficiency can be greatly improved under the same anode weight; and during the mounting, the tuck net-shaped sacrificial anode can be directly tiled underwater or suspended around structures without contacting water, so that the preliminary construction and the later change, especially the change of deepwater areas are very convenient.
Description
Technical field
The present invention relates to a kind of string bag shape sacrificial anode.
Background technology
When the ocean steel construction thing just descended water, galvanic protection was in the polarization stage at initial stage, and this stage needs sacrificial anode that very big electric current is provided.And after getting into the stage of stable development, the needed electric current of keeping can reduce greatly.In order to satisfy initial stage polar needs, get required high current density of initial stage usually and come design calculation during cathodic Protection Design, this has increased the anode consumption greatly.Not only cause anode material waste, increased the load behind the steelwork welding anode, increased the pollution of anode, and increased energy consumption seawater.Therefore, must research and development can polarize in the early stage the sacrificial anode of big electric current extremely is provided.
Summary of the invention
The purpose of this invention is to provide a kind of maritime works with string bag shape sacrificial anode, the mode that through changing traditional GB anode shape and size, take to increase anode water receiving area, reduces anodic water receiving resistance improves unit volume anodic generation electric current.
A kind of maritime works provided by the invention comprises the string bag shape matrix that is formed by connecting on some wireropes with string bag shape sacrificial anode; Said string bag shape matrix is provided with several sacrificial anode bodies.
Above-mentioned string bag shape sacrificial anode, said some wireropes can connect through welding process.
Above-mentioned string bag shape sacrificial anode, the diameter of sizing grid, size and the said wirerope of said string bag shape matrix can be confirmed according to the gross weight and the construction requirement of said sacrificial anode body.
Above-mentioned string bag shape sacrificial anode, said sacrificial anode body can be aluminium sacrificial anode, magnalium sacrificial anode or zinc sacrificial anode.
Above-mentioned string bag shape sacrificial anode, the shape of said sacrificial anode body can be trapezoidal or spherical.
Above-mentioned string bag shape sacrificial anode, the quantity of said sacrificial anode body can be confirmed according to calculation result.
Above-mentioned string bag shape sacrificial anode is connected with negative electrode utmost point tie cable on the tie point of said string bag shape matrix, be used for being electrically connected with protected object.
When using above-mentioned string bag shape sacrificial anode, can said string bag shape sacrificial anode be placed under water with the tiling mode, perhaps invest on the structures with hang.
String bag shape sacrificial anode provided by the invention; Traditional bulk GB anode is made the fritter volume to be become string bag shape to increase anode water receiving area just can to reduce anode water receiving resistance as far as possible; Under same anode weight, can improve anode generation electric current greatly, improve anode efficiency; Can directly throw in during installation and be tiled under water, also can take hang, can connect under water attached to around the structures, no matter to the initial stage construction still the later stage change, especially change very convenient to deepwater regions.
Description of drawings
Fig. 1 is the structural representation of string bag shape sacrificial anode of the present invention.
Each mark is following among the figure: 1 flexible wirerope, 2 welds, 3 aluminium sacrificial anodes, 4 negative electrode tie cables.
Embodiment
The following accompanying drawing that combines further specifies the present invention, but the present invention is not limited to following examples.
The string bag shape sacrificial anode that present embodiment provides comprises the string bag shape matrix that is formed by connecting through weld 2 on 6 flexible wireropes 1; Be provided with 24 aluminium sacrificial anodes 3 altogether on this string bag shape matrix, wherein every flexible wirerope 1 is provided with 4 aluminium sacrificial anodes 3; This aluminium sacrificial anode 3 is trapezoidal; Be connected with negative electrode tie cable 4 on 2 welds 2, be used for being electrically connected with protected object.
In the above-mentioned string bag shape sacrificial anode, the sacrificial anode body also can be magnalium sacrificial anode or zinc sacrificial anode; The shape of sacrificial anode body also can be sphere; The quantity of sacrificial anode body can be confirmed according to calculation result; The diameter of the sizing grid of string bag shape matrix, size and flexible wirerope 1 can be confirmed according to the gross weight and the construction requirement of sacrificial anode body; Also can connect between the flexible wirerope 1 through alternate manner.
When using above-mentioned string bag shape sacrificial anode; Can this pocketed sacrificial anode be suspended on by the protective surface and perhaps directly be tiled in bottom; With the negative electrode tie cable be electrically connected by protective, this pocketed sacrificial anode sends protective current, by protective be able to the polarization and the protection.
