Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific implementation mode of the present invention.
As shown in Figure 1, the overall structure diagram of present invention sea pipe sacrificial anode card, including sacrificial anode block 1, for solid
Fixing device 2, a pair of of baffle 3 and the position limiting structure 4 being scheduled on extra large pipe;Sacrificial anode block 1 casts in fixing device 2 respectively
Left and right outside;Baffle 3 is arranged in 2 bottom of fixing device and is rotatably connected with fixing device 2;The setting of position limiting structure 4 is being kept off
3 lower part of plate limits the slewing area of baffle 3.
The sacrificial anode block 1 is higher than the materials synthesis of extra large pipe steel sea tube layer, such as zinc, aluminium alloy by chemical activity
Equal materials play the role of protection extra large tube layer surface;In addition, sacrificial anode block is fixedly connected on fixed dress by modes such as casting
It sets on 2, the area of sacrificial anode block is big, can cover 2 both sides of fixing device, resistance to consumption, and service life is long;Meanwhile with sacrificial
The consumption of domestic animal anode block, sacrificial anode are also not easy to loosen or fall off.
The fixing device 2 is used as sacrificial anode card main structure, and there is higher intensity can carry sacrificial anode block, passes through
Collision is also less likely to be damaged, while also having good conductive property.Therefore fixing device 2 can by carbon steel, synthesize metal etc.
The high and material with excellent conductive performance of intensity is made;In addition, the opening shape of fixing device 2 and size are according to extra large pipe
What model and size were made, the opening width tapers into from the bottom to top, when extra large pipe is completely into in opening, Hai Guan
Top half can be bonded with 2 inner surface of fixing device completely.
2 bottom of the fixing device is provided with baffle 3, and baffle 3 is rotatablely connected with fixing device 2, can be connected by screw rod
It connects, naturally it is also possible to rotation connection be achieved by other means;Further, position limiting structure 4 is set in 3 lower end of baffle, such as
Iron staff, steel plate etc. prevent baffle 3 from rotating down.Under natural conditions, baffle 3 is stuck on position limiting structure 4, the length setting of baffle 3
So that opening width is less than the diameter of extra large pipe at baffle 3, under external force, extra large pipe pushes baffle 3 to be rotated up, when sea has been managed
It enters in fixing device 2, disappears to the active force of baffle 3, baffle 3 is stuck in again on position limiting structure 4 entirely.Further, it keeps off
The design strength of plate 3 is less than extra large pipe outer ring structure intensity, when fishing net or other seabed objects are outer to the application of sacrificial anode card structure
Power and applied stress intensity reaches certain value, when inevitably bringing damage, 3 structure of baffle is first corrupted such that sacrifice
Anode card is detached from sea pipe, and extra large pipe is avoided to be damaged.
Further, the top of the fixing device 2 is provided with T-type thread handle 5, the T-type thread handle 5 with it is described solid
Device 2 is determined by being detachably connected through the screw hole 6 at 2 top of the fixing device;The length of T-type thread handle 5 is more than spiral shell
The length in hole 6, and beyond partial action in making sea pipe contact with baffle 3 on extra large pipe enough.In addition, T-type thread handle 5 is also unsuitable
Long, the part that 2 outside of fixing device is exposed after installation is complete is less than the height of handle 7, avoids the objects such as fishing net in seabed
It hangs on T-type thread handle 5, applies external force, destroy sacrificial anode card;In addition, the quantity of screw hole 6 can be multiple, in fixation
2 top different location of device is respectively arranged, and T-type thread handle 5 may be selected position appropriate and carry out spiral reinforcing;Certainly, also may be used
Two or more T-type thread handles are according to circumstances arranged to be fixed.
Another preferred embodiment is provided at both ends with handle 7 in 2 top outer of the fixing device.The handle 7 is just
In ROV carry out underwater operation, can Fast Installation, improve efficiency, and stability is good;Meanwhile the sea pipe of the present embodiment being installed
Anode loss protection card, does not need diver, reduces cost.
The extra large pipe sacrificial anode card installation process of the present invention is further illustrated in conjunction with attached drawing 2-4, before installation, by T-type spiral shell
Line handle 5 rotates to a bit of position in screw hole 6, does not get higher than fixing device 2 or is detached from fixing device 2;Operate ROV manipulators
The sacrificial anode card extra large pipe of alignment that is open is inserted into, baffle can be opened slowly, is rotated up under external force, when sea pipe completely into
Enter into fixing device 2, baffle can be automatically closed;ROV manipulators are operated again and tighten T-type thread handle 5, and extra large tube top is risen, is pushed away
Dynamic sea pipe contacts baffle 3, and extra large pipe sacrificial anode card is secured firmly on extra large pipe, completes installation.
It should be understood that above example only expresses the preferred embodiment of the present invention, description is more specific and detailed
Carefully, but it cannot be construed as a limitation to the scope of the present invention;It should be pointed out that for the common skill of this field
For art personnel, without departing from the inventive concept of the premise, above-mentioned technical characterstic can be freely combined, can also be done
Go out several modifications and improvements, these are all within the scope of protection of the present invention;Therefore, all to be done with scope of the invention as claimed
Equivalents and modification, should all belong to the covering scope of the claims in the present invention.
