Technical Field
[0001] The utility model relates to the technical field of cathodic protection magnesium alloy sacrificial anode, in particular to a cathodic protection magnesium alloy sacrificial anode. Background Art
[0002] When metal materials interact with electrolytes, a primary cell is formed due to the uneven composition of the metal interface. As a result, there are different tendencies to gain and lose electrons on the metal surface, thereby generating a microcurrent. The anode metal of the primary cell loses electrons and is oxidized to a higher valence state, causing metal corrosion.
[0003] Cathodic protection technology is a type of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes the cathode, thereby inhibiting the electron migration caused by metal corrosion and avoiding or weakening the occurrence of corrosion.
[0004] The existing cathodic protection magnesium alloy sacrificial anode device cannot clamp the inner and outer walls of the steel pipe at the same time and perform cathodic protection according to the steel pipes of different sizes during the clamping process of the steel pipe. The failure to perform cathodic protection on the inner and outer walls of the steel pipe at the same time can easily cause the inner wall or the outer wall of the steel pipe to be corroded, causing corrosion damage to the steel pipe. In order to solve this technical problem, the utility model proposes a cathodic protection magnesium alloy sacrificial anode. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In the utility model, the first connecting rod is rotated to make the first gear and the second gear rotate at the same time, and the mutual meshing between the first gear and the first tooth plate and the mutual meshing between the second gear and the second tooth plate make the two first support plates and the two second support plates move horizontally toward or in the opposite direction of the center of the magnesium alloy bracket at the same time. At the same time, when the first support plate moves horizontally toward the center of the magnesium alloy bracket, the second support plate moves in the opposite direction of the center of the magnesium alloy bracket, thereby achieving the effect that the device can perform cathodic protection on the inner and outer walls of steel pipes of different sizes by extruding the first magnesium alloy sheet into contact with the inner wall of the steel pipe and the second magnesium alloy sheet into contact with the outer wall of the steel pipe.
[0016] In the utility model, when the inner and outer walls of the steel pipe are cathodically protected by the rotation of the first connecting rod, the first spring and the second spring will be compressed at the same time, and the elasticity of the first spring and the second spring acts on the corresponding first magnesium alloy sheet and the second magnesium alloy sheet, making them elastic, thereby preventing the inner wall or outer wall of the steel pipe from being unable to contact the magnesium alloy sheet when the inner wall or outer wall of the steel pipe contacts the corresponding first magnesium alloy sheet and the second magnesium alloy sheet, resulting in failure to obtain the cathodic protection effect.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1 - Figure 4 As shown, a cathodic protection magnesium alloy sacrificial anode comprises a magnesium alloy bracket 1, the outer surface of the magnesium alloy bracket 1 is provided with four T-slots 5, wherein the inner walls of two T-slots 5 are slidably connected with first support plates 6, the inner wall of each first support plate 6 is slidably connected with a second connecting rod 7, the ends of the two second connecting rods 7 away from each other are fixedly connected with a first magnesium alloy sheet 8, the sides of the two first support plates 6 close to each other are fixedly connected with a first toothed plate 14, the inner walls of the other two T-slots 5 are slidably connected with second support plates 10, and the ends of each second support plates 10 close to each other are fixedly connected with a first magnesium alloy sheet 8. A second tooth plate 15 is fixedly connected, and the magnesium alloy bracket 1 serves as a sacrificial anode for cathodic protection of the steel pipe. The first support plate 6 and the second support plate 10 can slide horizontally along the corresponding T-slot 5. The horizontal sliding of the first support plate 6 can drive the corresponding first tooth plate 14 to move horizontally, and the horizontal sliding of the second support plate 10 can drive the corresponding second tooth plate 15 to move horizontally. At this time, the second connecting rod 7 will follow the horizontal movement of the corresponding first support plate 6, and can squeeze and contact the inner wall of the steel pipe through the first magnesium alloy sheet 8, so as to increase the support of the inner wall of the steel pipe and the cathodic protection of the inner wall of the steel pipe.
[0024] like Figure 1 , Figure 3As shown, the outer surface of each second connecting rod 7 is sleeved with a first spring 9, and the ends of the two first springs 9 close to each other are fixedly connected to the corresponding first support plate 6, and the other ends are fixedly connected to the corresponding first magnesium alloy sheet 8. When the first support plate 6 moves horizontally, when the second connecting rod 7 pushes the corresponding first magnesium alloy sheet 8 to move horizontally and squeezes and supports the inner wall of the steel pipe, the first spring 9 begins to compress slowly, and the resilience of the first spring 9 can increase the extrusion elasticity of the first magnesium alloy sheet 8.
[0025] like Figure 1 , Figure 2 As shown, the ends of the two second support plates 10 that are away from each other are fixedly connected to the third connecting rod 11, and the outer surface of each third connecting rod 11 is slidably connected to the second magnesium alloy sheet 12. The horizontal sliding of the second support plate 10 drives the second magnesium alloy sheet 12 to clamp the outer wall of the steel pipe through the third connecting rod 11.
[0026] like Figure 1 , Figure 2 As shown, the outer surface of each third connecting rod 11 is sleeved with a second spring 13, and the ends of the two second springs 13 that are away from each other are fixedly connected to the corresponding third connecting rod 11, and the other ends are fixedly connected to the corresponding second magnesium alloy sheets 12. When the horizontal sliding of the third connecting rod 11 drives the corresponding second magnesium alloy sheet 12 to clamp the outer wall of the steel pipe, the elastic force of the second spring 13 enables the second magnesium alloy sheet 12 to elastically clamp the outer wall of the steel pipe.
[0027] like Figure 3 As shown, the inner wall of the magnesium alloy bracket 1 is rotatably connected to the first connecting rod 2, and the end of the first connecting rod 2 close to the first support plate 6 is fixedly connected to the first gear 3, and the outer surface of the first gear 3 is meshed with the two first tooth plates 14. The rotation of the first connecting rod 2 can drive the first gear 3 to rotate, and the rotation of the first gear 3 will enable the first tooth plate 14 to push the corresponding first support plate 6 to move horizontally through the meshing with the first tooth plate 14. At this time, the two first tooth plates 14 will move horizontally in opposite directions or reverse directions along the magnesium alloy bracket 1 at the same time.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the second gear 4 is fixedly connected to the side of the first gear 3 away from the first connecting rod 2, and the outer surface of the second gear 4 is meshed with the two second tooth plates 15. The end of the first connecting rod 2 away from the first gear 3 is plugged with a fixing plate 16 and a rotating wheel 17, and the outer surface of the fixing plate 16 is rotatably connected to the magnesium alloy bracket 1. The rotation of the first gear 3 will drive the second gear 4 to rotate at the same time, and through the mutual meshing of the second gear 4 and the second tooth plate 15, the second tooth plate 15 can move horizontally opposite or reversely along the magnesium alloy bracket 1 at the same time. At the same time, when the two second tooth plates 15 move horizontally toward the center of the magnesium alloy bracket 1, the two first tooth plates 14 will move horizontally in the opposite direction of the center of the magnesium alloy bracket 1 at the same time. At this time, the first magnesium alloy sheet 8 and the second magnesium alloy sheet 12 can clamp the inner wall and the outer wall of the steel pipe through the cross movement of the first tooth plate 14 and the second tooth plate 15, and the first connecting rod 2 can be easily rotated by the rotating wheel 17.
[0029] like Figure 1 , Figure 3 As shown, two limit plates 18 are fixedly connected to the outer surface of the magnesium alloy bracket 1, and the outer surface of each limit plate 18 is slidably connected to the corresponding first tooth plate 14 and second tooth plate 15. The limit plates 18 can limit the first tooth plate 14 and the second tooth plate 15 to prevent them from falling off.
[0030] The principle of the utility model is as follows: firstly, the magnesium alloy support 1 is placed at the end of the steel pipe, and the rotating wheel 17 is rotated at this time, which drives the first connecting rod 2 to rotate, and thereby drives the first gear 3 and the second gear 4 to rotate simultaneously, and at this time, the meshing between the first gear 3 and the two first tooth plates 14 makes the two first tooth plates 14 drive the corresponding first support plates 6 to move horizontally toward the central axis of the magnesium alloy support 1 in the opposite or opposite direction, and at this time, the meshing between the second gear 4 and the two second tooth plates 15 makes the two second tooth plates 15 drive the corresponding second support plates 10 to move horizontally toward the central axis of the magnesium alloy support 1 in the opposite or opposite direction. When the two first support plates 6 move horizontally toward the central axis of the magnesium alloy bracket 1, the two second support plates 10 will move horizontally in the opposite direction toward the magnesium alloy bracket 1. At this time, the inner wall and outer wall of the steel pipe of different sizes are clamped at the same time through the cross movement of the two first support plates 6 and the second support plates 10. In this process, the first magnesium alloy sheet 8 and the second magnesium alloy sheet 12 contact the inner and outer walls of the steel pipe, and the first spring 9 and the second spring 13 are gradually compressed until the first magnesium alloy sheet 8 and the second magnesium alloy sheet 12 are tightly clamped with the inner and outer walls of the steel pipe. At this time, the magnesium alloy sheet can be used as a sacrificial anode for cathodic protection.
