Description
Technical field
The utility model is related to a kind of ocean platform impressed current cathodic protection facility, more particularly to a kind of ocean platform
Auxiliary anode device in impressed current cathodic protection system.
Background technology
In the prior art, if being protected to in-service ocean platform, with reference to gravity type anode system, mainly there are three kinds at present
Mode.
1. fixation clamp is installed：Anode is fixed on the clamp of jacket, advantage is to install relatively to fix, and cable is protected
Shield is convenient, and shortcoming is that underwater construction operation project and task amount are more, and due to that can only be fixed on below ocean platform, extremely
Easily cause the shielding of electric current.
2. piling mode, underwater steel pile support is mounted on by anode, and advantage is more closed for anode position can be positioned over
The position of reason, fixed relatively to stablize, shortcoming is that construction workload is larger, costly；
3. concrete sticks together again：Anode is mounted on and is placed on the concrete in seabed and is sticked together again, advantage is construction more letter
Single, expense is relatively low, and shortcoming is marine site when being shale sea bed, and sea bed is unstable, because sticking together movement again, and can cause cable breakage.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of ocean platform impressed current cathodic protection system
Middle auxiliary anode device, by the technical program, the installation for solving anode is fixed, while having economy higher.
In order to achieve the above object, the technical solution of the utility model is realized in：
Auxiliary anode device in a kind of ocean platform impressed current cathodic protection system, including support spud leg and anode electricity
Cable, also including anode, anode rod, anode base, concrete anchor block, the support spud leg is three and is laid out in isosceles triangle, branch
Support spud leg top is provided with anode and fixes stull, and the two ends that each anode fixes stull are mutually fixed with adjacent support spud leg respectively
Connection, the anode rod upper end is fixedly connected with anode, and anode rod lower end is fixedly connected with anode base, anode base and anode rod
The superstructure of bottom and support spud leg is cast in concrete anchor block, and anode cable is reserved in concrete anchor block,
And be connected with anode base.
Used as further technical scheme, the concrete anchor block is square bucking ladder, the concrete anchor block
Angle between surrounding four sides and concrete anchor block bottom surface is 60 ° -80 °.
Used as further technical scheme, the concrete anchor block outside is provided with glass fibre reinforced plastics casing.
Used as further technical scheme, the anode is ball anode.
It is using the beneficial effect after above-mentioned technical proposal：Aided in a kind of ocean platform impressed current cathodic protection system
Anode assembly, by the technical program, enables impressed current anode to be fixedly mounted faster in seabed, and simple structure, manufacture
Easily, low cost, is the preferred plan of aged ocean platform reconstruction ocean platform protection.
Brief description of the drawings
Fig. 1 is that unitary side of the present utility model regards schematic cross-sectional view.
Fig. 2 be Fig. 1 in A-A to schematic cross-sectional view.
In figure, 1 support spud leg, 2 anode cables, 3 anodes, 4 anode rods, 5 anode bases, 6 concrete anchor blocks, 7 anodes
Fixed stull, 8 glass fibre reinforced plastics casings.
Specific embodiment
Specific embodiment in the utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, impressed current anode in the ocean platform impressed current cathodic protection system that the utility model is related to
Device, including support spud leg 1 and anode cable 2, also including anode 3, anode rod 4, anode base 5, concrete anchor block 6, institute
Support spud leg 1 is stated for three are laid out in isosceles triangle, support spud leg 1 top is provided with anode and fixes stull 7, each anode fixes horizontal stroke
The two ends of support 7 are mutually fixedly connected with adjacent support spud leg 1 respectively, and the upper end of the anode rod 4 is fixedly connected with anode 3, anode rod 4
Lower end is fixedly connected with anode base 5, and the superstructure and anode of the bottom and support spud leg 1 of anode base 5 and anode rod 4 are fixed
Stull 7 is cast in concrete anchor block 6, and anode cable 2 is reserved in concrete anchor block 6, and is connected with anode base 5
It is logical.
Used as further embodiment, the concrete anchor block 6 is square bucking ladder, the concrete anchor block 6
Angle between surrounding four sides and the bottom surface of concrete anchor block 6 is 75.
Used as further embodiment, the outside of the concrete anchor block 6 is provided with glass fibre reinforced plastics casing 8.
Used as further technical scheme, the anode 3 is ball anode.
The utility model when mounted, is supported on the harder position of sea bed lower floor by supporting spud leg 1, and concrete is fixed
Pier 6 is sunk in the ooze of sea bed, is slowly sunk, and the concrete anchor block 6 is buried by ooze, due to concrete anchor block
Go up greatly small under 6, the muddy water of surrounding is crowded on concrete anchor block 6, and in the effect of support spud leg 1, substantially increase entirety
Stability, effectively prevent displacement, the glass fibre reinforced plastics casing 8 of the outer cladding of concrete anchor block 6 has effectively isolated seawater pair
The erosion of concrete anchor block 6, substantially increases work service life.
The bottom of support spud leg 1 can be pointed by being made in the utility model, to be inserted into the ooze of sea bed.
The above, preferable possible embodiments only of the present utility model are not limited to of the present utility model
Scope.
