Technical Field
[0001] The utility model relates to the technical field of sacrificial anodes, and more particularly to a high-potential magnesium alloy sacrificial anode. Background Art
[0002] The high-potential magnesium alloy sacrificial anode is a metal anode produced from high-quality high-purity magnesium materials, with specific electrochemical properties, and is applicable to the cathodic protection process. The sacrificial anode mainly consists of a metal connection core and a sacrificial anode metal. The metal connection core is the steel core, and the steel core is divided into round steel and strip steel.
[0003] When the magnesium sacrificial anode is used, it must be placed in a stuffing bag and then buried. Since the bag body is relatively soft and the stuffing is easy to flow, the position of the anode is likely to move, resulting in the problem that it cannot fully contact the stuffing.
[0004] Therefore, there is an urgent need for a high-potential magnesium alloy sacrificial anode. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a high-potential magnesium alloy sacrificial anode to solve the problems in the background art.
[0006] To solve the above technical problems, the technical solutions adopted by the utility model are as follows.
[0007] A high-potential magnesium alloy sacrificial anode includes an anode body, and a wire extends from the middle of the upper end face of the anode body; the anode body is arranged in a stuffing bag, the stuffing bag is filled with stuffing, and a binding rope for tying the bag mouth and the wire is arranged at the bag mouth of the stuffing bag; insulating rods are arranged at both ends of the anode body along the length direction of the anode body, the insulating rod at the top is connected with a first insulating frame, and the insulating rod at the bottom is connected with a second insulating frame; several support rods are connected between the two insulating frames, and there is a certain distance between the support rods and the anode body; a fixed snap ring is arranged on the wire inside the stuffing bag, and the fixed snap ring is located at the bag mouth of the stuffing bag.
[0008] Further optimizing the technical solution, the first insulating frame is a cross-shaped frame.
[0009] Further optimizing the technical solution, the second insulating frame has the same shape as the first insulating frame and is arranged in parallel, and the support rod is connected between the ends at the same position of the first insulating frame and the second insulating frame.
[0010] Further optimizing the technical solution, the length of the wire below the fixed snap ring is greater than the straight-line distance from the fixed snap ring to the center of the upper end face of the anode body when the anode body is farthest from the upper tying mouth of the stuffing bag.
[0011] Due to the adoption of the above technical solutions, the technical progress obtained by the utility model is as follows.
[0012] A high-potential magnesium alloy sacrificial anode provided by the utility model ensures that the anode body can still be in full contact with the filler for the primary battery reaction after corrosion by setting an insulating frame, insulating rods and support rods; by setting a fixing clamp ring, it can protect the wire after the anode body corrodes and displaces, and will not cause excessive pulling to break the wire. The utility model has the advantages of simple structure and convenient use, and can ensure the stability and long-term effectiveness of the sacrificial anode. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.
[0016] A high-potential magnesium alloy sacrificial anode, in combination with Figure 1 as shown, includes an anode body 1, insulating rods 2, a first insulating frame 31, a second insulating frame 32, support rods 4, a wire 5, a fixing clamp ring 9, a filler bag 6, a filler 7, and a binding rope 8.
[0017] The wire 5 extends out from the middle of the upper end face of the anode body 1.
[0018] The anode body 1 is arranged in the filler bag 6, the filler bag 6 is filled with a filler 7, and a binding rope 8 is arranged at the opening of the filler bag 6 for tying the bag mouth and the wire 5.
[0019] Insulating rods 2 are arranged at both ends of the anode body 1, the insulating rods 2 are arranged along the length direction of the anode body 1, the insulating rod 2 at the top is connected with a first insulating frame 31, the first insulating frame 31 is a cross-shaped frame and is horizontally arranged to ensure being parallel to the end face of the anode body 1. The insulating rod 2 at the bottom is connected with a second insulating frame 32, and the second insulating frame 32 has the same shape as the first insulating frame 31 and is arranged in parallel.
[0020] A plurality of support rods 4 are connected between the two insulating frames, and the support rods 4 are connected between the ends at the same position of the first insulating frame 31 and the second insulating frame 32. There is a certain distance between the support rods 4 and the anode body 1 to ensure full contact between the anode body 1 and the filler 7.
[0021] A fixing snap ring 9 is provided on the wire 5 located inside the packing bag 6, and the fixing snap ring 9 is located at the mouth of the packing bag 6. The length of the wire 5 below the fixing snap ring 9 is greater than the straight-line distance from the fixing snap ring 9 to the center of the upper end face of the anode body 1 when the anode body 1 is at the farthest position from the mouth of the packing bag 6, so as to ensure that when the anode body 1 is at any position in the packing bag 6, the wire 5 in the packing bag 6 is still sufficient for use and is not taut.
[0022] When the utility model is actually used, the anode body, the insulating rod, the first insulating bracket, the second insulating bracket and the support rod are assembled and connected, and a fixing snap ring is installed at a suitable position on the wire. Then, the connected whole is put into the packing bag for encapsulation. The anode body is limited in the packing bag, the packing is wrapped around the anode body, and the fixing snap ring and the wire part below the fixing snap ring are sealed in the packing bag through a binding rope. The support rod supports the anode body, so that the surface of the anode body does not directly contact the soil pit, and it is ensured that the anode body is in full contact with the packing. Then, the packing bag is soaked and filled with soil. With the sacrificial corrosion of the anode, it can still be ensured that the anode body is in full contact with the packing, ensuring the effectiveness of the sacrificial anode protection method.
