Description

A kind of sea cable centralized positioning protection device
Technical field
The present invention relates to a kind of sea cable centralized positioning protection device, be applied to the field such as oil platform, wind-powered electricity generation sea cable, it is made With being to protect sea cable, the centralized positioning in protection pipe of the sea cable and traction etc..
Background technology
Marine cable is the wire by wrapped with insulation, be laid on seabed in order to set up between country and country, island And between inland, between oil platform and inland, the important communication equipment in the place such as military installations over strait.Along with China is to the energy Demand increases day by day, and the dynamics of marine oil and gas, offshore wind farm exploitation the most rapidly strengthens.The important matchmaker that sea cable transmits as electric power Being situated between, security reliability in use is most important.Oil platform or offshore wind farm marine sea cable are to be protected by rigidity Pipe is worn above platform from seabed, smooth for poling, and sea cable pillar internal diameter is usually about 3 times of sea cable external diameter.Therefore sea cable Can freely swing in pillar, particularly in exit, pillar lower end, at this, cable feeling the current in sea is the most violent, at ocean current Can not stop under Zuo Yong dynamic, constantly collide pillar simultaneously, the endurance failure of cable can be caused under long duration of action, cause cable Cannot transmit electricity, ultimately result in whole power system paralysis, thus cause huge economic loss.
The most conventional guard method is to utilize weight to push down going out pillar sea cable, stops sea cable to move, and the method can Having the movement controlling sea cable in short time, but under long-term ocean current effect, weight can be flushed away, sea cable can arbitrarily be put again Dynamic.Therefore exploitation one is capable of sea cable centralized positioning in pillar, and the device stoping sea cable arbitrarily to swing in pillar is outstanding For important.
Summary of the invention
The invention aims to solve deficiency of the prior art, it is provided that one can be pillar lower port section sea cable It is limited in pillar center, effectively controls sea cable and swing in pillar, prevent from producing collision with rigidity pillar, it is to avoid sea cable exists Endurance failure occurs under the long term of ocean current, and simple in construction, easy for installation, reliability is high, in the extra large cable of service life length Heart positioning protection device.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of sea cable centralized positioning Protection device, including transition connecting apparatus and flange, described flange is arranged on one end of transition connecting apparatus, described transition The inside of attachment means is provided with installation draw-in groove and centre bore, and described transition connecting apparatus and flange are all divided into two by centrage Hemihedrism structure, the external margin of described transition connecting apparatus is respectively arranged with, by centrage, the dormant bolt that symmetry is offered Hole, also include bolt, described bolt be arranged in the dormant bolt hole that symmetry is offered by two halves transition connecting apparatus pretension in One overall transition connecting apparatus.
In a preferred embodiment of the present invention, the described cross section crossing attachment means and flange is circular configuration.
In a preferred embodiment of the present invention, the described diameter crossing attachment means is less than the diameter of flange.
In a preferred embodiment of the present invention, described flange is provided with multiple evenly distributed bolt hole.
In a preferred embodiment of the present invention, the diameter of described centre bore is more than the external diameter of sea cable.
In a preferred embodiment of the present invention, the described outer surface crossing attachment means is coated with corrosion-inhibiting coating.
The invention has the beneficial effects as follows: a kind of sea cable centralized positioning protection device of the present invention, it is possible to sea cable bending limit Device processed couples together with J-type pipe, it is possible to sea cable is limited in J-type pipeline center position, can be effectively protected sea cable and make it avoid The collision of rigidity, impacting and be conducive to the traction of sea cable, it has simple in construction, intensity is high, corrosion-resistant, easy for installation, make By advantages such as year limits for length.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only some embodiments of the present invention, for From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings Accompanying drawing, wherein:
Fig. 1 is the perspective view of a preferred embodiment of the extra large cable centralized positioning protection device of the present invention;
Being labeled as in accompanying drawing: 1, transition connecting apparatus, 2, flange, 3, bolt, 11, draw-in groove is installed, 12, centre bore, 13, countersunk head Bolt hole, 21, bolt hole.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common All other embodiments that technical staff is obtained under not making creative work premise, broadly fall into the model of present invention protection Enclose.
As it is shown in figure 1, the embodiment of the present invention includes:
A kind of sea cable centralized positioning protection device, including transition connecting apparatus 1 and flange 2, described flange 2 is arranged on transition even One end of connection device 1, the inside of described transition connecting apparatus 1 is provided with installation draw-in groove 11 and centre bore 12, and described transition is even Connection device 1 and flange 2 are all by centrage dimidiation symmetrical structure, and the external margin of described transition connecting apparatus 1 passes through Centrage is respectively arranged with the dormant bolt hole 13 that symmetry is offered, and also includes that bolt 3, described bolt 3 are arranged on symmetry and offer Dormant bolt hole 13 in be an overall transition connecting apparatus 1 by two halves transition connecting apparatus 1 pretension.
