Description

Technical Field

[0001] This utility model relates to the field of metal corrosion protection structures, and in particular to an anode block mounting frame and a sacrificial anode block assembly. Background Technology

[0002] Sacrificial anode cathodic protection is a commonly used metal protection method in marine engineering. The sacrificial anodes frequently used in ports and marine engineering are usually aluminum alloy anodes or zinc alloy anodes. In the cathodic protection system, an oxidation reaction occurs, and current is guided to the protected structure through a conductor, thereby causing the protected structure to undergo a reduction reaction and become a cathode. This inhibits the oxidation reaction on the protected structure, thereby slowing down or preventing the corrosion process of the protected structure.

[0003] Since the corrosion protection provided by a single anode block is limited, existing marine engineering projects generally connect multiple anode blocks in series and float them in the water, or integrate multiple anode blocks together to form an anode stack and fix it on the seabed. However, floating anode blocks are very easy to shift and affect the passage of ships, while anode stacks installed on the seabed require manual diving for welding and fixing operations. Diving operations pose huge safety risks and have significant potential construction hazards. In addition, the rental cost of diving auxiliary equipment is high, resulting in high installation costs and low efficiency of underwater anode stacks. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the need for manual diving for welding and fixing of existing anode stacks underwater, which is risky, costly and inefficient. This invention provides an anode block mounting frame and a sacrificial anode block assembly.

[0005] In a first aspect, the present invention provides an anode block mounting frame, comprising:

[0006] The bottom frame is equipped with a junction box and a counterweight casting cavity. The junction box is used to connect the anode cable, and the counterweight casting cavity is equipped with a steel mesh structure, which is welded to the bottom frame.

[0007] A top frame is disposed above the bottom frame and connected to the bottom frame by several connecting rods. The top frame is provided with lifting lugs.

[0008] This utility model discloses an anode block mounting frame. By providing an anode block mounting frame with a counterweight casting cavity, counterweight material can be cast into the counterweight casting cavity according to actual needs to set the counterweight. The mounting frame can sink to the bottom of the water and be fixed under its own weight. The mounting frame can be easily prefabricated, and the anode blocks can be pre-welded to the mounting frame. Multiple anode blocks can be fixed underwater without underwater welding operations, reducing the risks of diving operations. Moreover, the counterweight can be changed by adjusting the casting volume according to actual conditions to adapt to the smooth installation of anode blocks at different water levels, reducing the risks and costs of underwater installation of anode blocks and improving installation efficiency.

[0009] Preferably, both the bottom frame and the top frame are welded steel structural components, and the connecting rod is a steel rod-shaped structural component.

[0010] Preferably, both the top frame and the bottom frame are polygonal frame structures, and the connecting rods are connected to the corners of the top frame and the bottom frame. This forms a cage-like mounting frame, providing more mounting positions for the anode blocks.

[0011] Preferably, the projected area of ​​the top frame on the bottom frame is smaller than that of the bottom frame. The mounting frame, forming a frustum-shaped structure, lowers the overall center of gravity and improves its stability.

[0012] Preferably, the junction box includes an outer frame component and a top cover, the top cover being detachably connected to the outer frame component, and the outer frame component having a through hole adapted to the anode cable. This ensures that the welding position of the anode cable to the mounting frame is well protected by the junction box, guaranteeing a long-term effective connection between the anode cable and the mounting frame.

[0013] Preferably, the bottom frame is provided with several wire clamping sections, each wire clamping section is detachably connected to a crimping member, and a rubber pad is provided between the crimping member and the wire clamping section. This further ensures that the anode cable and the mounting frame are effectively connected for a long period of time.

[0014] Preferably, the bottom frame is provided with a plurality of limiting posts at its bottom, and each limiting post has a pointed end. This allows the limiting posts to penetrate the seabed after the mounting frame sinks to the bottom, further improving the underwater stability of the mounting frame.

[0015] Preferably, a circular winding member is provided on one side of the bottom frame. This member is used to wind the anode cable to prevent the connection between the anode cable and the mounting frame from being affected by the tension during the sinking process.

[0016] In a second embodiment, the present invention provides a sacrificial anode block assembly, including an anode block mounting frame as described above, and further including a plurality of anode blocks and anode cables. The anode blocks are provided with adapters, which are detachably connected to the connecting rods. The anode cables are welded to the bottom frame inside the junction box, and a plate-shaped structural component is cast in the counterweight casting cavity.

[0017] This utility model discloses a sacrificial anode block assembly. By detachably mounting the anode blocks on the connecting rods of the mounting frame, it is convenient to install and adjust the number of anode blocks. Furthermore, the number of connecting rods and the number of anode blocks on each connecting rod can be adjusted according to actual conditions to form a sacrificial anode block assembly integrating different numbers of anode blocks.

[0018] Preferably, the adapter includes an arc-shaped rod and a snap-fit ​​component. The arc-shaped rod is connected to the anode block, and the snap-fit ​​component has bolt holes. The snap-fit ​​component is detachably connected to the connecting rod by bolts.

[0049] In one or more embodiments, the steel mesh structure 3 can be a pre-woven mesh structure, a steel cage, or a mesh structure formed by multiple steel bars arranged in an interlaced manner. The steel mesh structure 3 can be welded to the bottom frame 1 or connected by steel bar insertion, so that the steel mesh structure 3 and the bottom frame 1 are connected as a whole, and can be cast into a plate-shaped structure for counterweight.

[0050] In an optional embodiment, concrete can be poured into the counterweight pouring cavity 11 to form a reinforced concrete slab, so that the steel mesh structure 3 is embedded in the concrete. The pouring volume can be adjusted according to the actual situation to adjust the center of gravity of the installation frame.

[0051] In an optional embodiment, the counterweight casting cavity 11 can be pre-drilled with water passage holes during casting or during the prefabrication of the steel mesh structure 3, so as to facilitate the smooth passage of water during the process of the installation frame sinking to the bottom of the water and reduce the sinking resistance.

[0052] In one or more embodiments, the projected area of ​​the top frame 4 on the bottom frame 1 is smaller than that of the bottom frame 1, so as to form a frustum-shaped mounting frame, thereby lowering the overall center of gravity of the mounting frame and improving the stability of the mounting frame.

[0053] In one or more embodiments, the junction box 2 includes an outer frame member 21 and a top cover 22, the top cover 22 being detachably connected to the outer frame member 21, and the outer frame member 21 having a through hole adapted to the anode cable 10.

[0054] In an optional embodiment, the outer frame component 21 is welded to the top surface of the bottom frame 1, and the wire hole is provided on the side wall of the outer frame component 21.

[0057] In one or more embodiments, the bottom frame 1 is provided with a plurality of limiting posts 7, and the bottom end of the limiting posts 7 is provided with a pointed part.

[0058] In an optional embodiment, the limiting post 7 can be a steel bar, steel rod, etc. with a pointed end, arranged at intervals along the bottom frame 1.

[0059] In one or more embodiments, a circular winding member 8 is provided on one side of the bottom frame 1. This member is used to wind the anode cable 10 to prevent the connection between the anode cable 10 and the mounting frame from being affected by the tension during the sinking process.

[0060] In an optional embodiment, the winding member 8 may be a ring welded to the bottom frame 1, and the anode cable 10 may be wound around the circumference of the ring and secured with cable ties to prevent the anode cable 10 from being sheared and worn by the edge of the mounting frame during and after the mounting frame is lowered, thereby reducing the life of the anode cable 10 or even directly damaging the anode cable 10.

[0061] This embodiment provides an anode block mounting frame. By providing an anode block 9 mounting frame with a counterweight casting cavity 11, counterweight material can be poured into the counterweight casting cavity 11 for counterweight setting. This allows the mounting frame to sink to the bottom of the water and be fixed under its own weight. The mounting frame can be easily prefabricated, and the anode block 9 can be pre-welded to the mounting frame.
