Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anodes, in particular to a zinc alloy sacrificial anode structure. Background Art

[0002] Zinc alloy sacrificial anode is a common anti-corrosion technology, usually used to protect steel structures from corrosion. It uses the high potential of zinc to make it voluntarily undergo oxidation reaction when in contact with steel structures, thereby protecting steel from corrosion. Zinc alloy sacrificial anode is often used to protect other metal components, such as steel, in corrosive environments. However, even zinc alloy anodes used to protect other metals require additional protective casings.

[0003] The protective shell of the conventional zinc alloy sacrificial anode structure is installed on the prepared corrosion-resistant plastic sheet, and the positions corresponding to the pre-prepared fixing points on the zinc alloy component are marked. Then, the plastic sheet is fixed to the zinc alloy component using bolts and nuts.

[0004] The protective shell device of the traditional zinc alloy sacrificial anode structure has the following problems: over time, due to various factors, the connection between the bolts and nuts may loosen, causing the plastic sheet to loosen and fall off, and the installation process of the bolts and nuts is relatively cumbersome, which makes it more troublesome to replace the zinc alloy sacrificial anode. For this reason, we propose a zinc alloy sacrificial anode structure. Utility Model Content

The left and right ends of the active metal are installed in conjunction with two vertically adjacent rubber strips, which reduces the vibration and external environment impact on the zinc alloy sacrificial anode or other components during use, thereby extending the service life of the device. At the same time, it can make the replacement of the zinc alloy sacrificial anode faster and more efficient, and improve overall flexibility.

[0010] Furthermore, the fixing mechanism includes an installation shell and a slot. The installation shell is respectively arranged at the front and rear ends of the lower surface of the upper polyethylene shell, and the slot is respectively opened at the front and rear ends of the upper surface of the lower polyethylene shell. The slots are plugged into the vertically adjacent installation shells for preliminary fixation.

[0011] Furthermore, the fixing mechanism includes an installation groove, a rotating shaft, a fixing plate and a card slot. The installation grooves are all opened inside the installation shell, and the rotating shaft is rotatably connected between the left and right inner walls of the installation groove. The outer surface of the rotating shaft is fixedly sleeved with a fixing plate. The card slots are all opened on the inner wall of the slot, and the top walls of the card slots are carded with the top of the vertically adjacent fixing plate, so that they can be fixed more firmly in the device, avoiding loosening and falling off due to vibration or external force.

[0012] Furthermore, the fixing mechanism also includes a rubber pad, which is arranged on one side of the slot close to the center of the polyethylene shell, and the outer surface of the rubber pad is installed in cooperation with the adjacent installation shell to improve the sealing between the connections.

[0013] Furthermore, the fixing mechanism also includes a spring 1, an arc-shaped sliding column and an arc-shaped sliding hole. The arc-shaped sliding holes are all opened on the inner wall of the mounting shell, the inner wall of the arc-shaped sliding hole is slidably connected with the arc-shaped sliding column, the outer end of the arc-shaped sliding column is fixedly connected to the inner side surface of the adjacent fixing plate, the inner side surface of the fixing plate and the inner wall of the mounting shell are fixedly connected with a spring 1, and the spring 1 is sleeved on the outer surface of the arc-shaped sliding column to improve the overall flexibility.

[0014] Furthermore, the release and fixing mechanism includes a rubber head, a fixed column, a sliding column and a sliding hole. The fixed columns are respectively fixedly connected to the front and rear sides of the polyethylene shell at the lower end. Sliding holes are opened inside the fixed columns. The sliding holes are connected to adjacent slots. The inner walls of the sliding holes are slidably connected to sliding columns. The inner ends of the sliding columns are provided with rubber heads. The rubber heads are installed in cooperation with the outer side surfaces of the adjacent fixing plates to facilitate contact and fixation of the fixing mechanism.

[0015] Furthermore, the release and fixing mechanism also includes a spring 2 and a button, and the buttons are fixedly connected to the outer end of the sliding column.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the zinc alloy sacrificial anode structure has the following advantages:

[0017] 1. Insert the installation shell on the upper polyethylene shell into the slot of the lower polyethylene shell. During the installation of the shell, the fixed plate is subjected to an extrusion force, which causes the fixed plate to rotate around the rotation axis at a certain angle. However, while the fixed plate is rotating, the spring 1 is compressed. The compression of the spring 1 causes the arc-shaped slide column to slide into the arc-shaped slide hole, thereby driving the fixed plate to rotate around the rotation axis as the center, providing an avoidance space for the installation shell to be plugged into the slot. When inserted to a certain depth, a card slot will appear. At this time, the spring 1 releases the elastic energy storage, driving the fixed plate and the arc-shaped slide column to rotate in the opposite direction around the rotation axis as the center. During the rebound process, the top of the fixing plate is engaged with the top wall of the slot, so that it can be more firmly fixed in the device, avoiding loosening and falling off due to vibration or external force, thereby fixing the upper and lower polyethylene shells, and also fixing the active metal, which can provide a more complete and continuous protective layer, avoiding direct contact of the corrosive medium with the zinc alloy, and reducing the vibration and external environment of the zinc alloy sacrificial anode or other components during use, thereby extending the service life of the device, and can be quickly installed, improving the subsequent work of the zinc alloy sacrificial anode.

[0018] 2. When replacing the zinc alloy sacrificial anode, press the button, and the button compresses spring 2. While compressing spring 2, the sliding column is driven to move into the sliding hole until the rubber head contacts the fixed plate at the adjacent end. The existence of the rubber head reduces direct contact with the fixed plate, thereby increasing the service life. Then, the rubber head applies an extrusion force to the fixed plate, and this extrusion force causes the fixed plate to rotate a certain angle around the rotation axis. However, while the fixed plate is rotating, spring 1 is compressed. The compression of spring 1 causes the arc-shaped sliding column to slide into the arc-shaped sliding hole, thereby driving the fixed plate to rotate around the rotation axis until it is separated from the top wall of the slot. Then, the polyethylene shell at the upper end is pulled upward. When moving, the polyethylene shell at the upper end drives the installation shell to separate from the slot, thereby separating the two polyethylene shells, thereby making the replacement of the zinc alloy sacrificial anode faster and more efficient, reducing the required manpower and time costs, and improving the overall flexibility.

[0025] See also Figure 1-4 ,This embodiment provides a technical solution: a zinc alloy sacrificial anode structure, including a polyethylene shell 1, a release and fixing mechanism 3 and an active metal 4;

[0026] Polyethylene shell 1: There are two of them, and both left and right ends of the two polyethylene shells 1 are provided with avoidance openings 7. First, the active metal 4 is placed inside the polyethylene shell 1 at the lower end, and it is ensured that the position and direction of the active metal 4 meet the design requirements and can be correctly connected with the polyethylene shell 1 at the upper end.

The arc-shaped slide hole 207 is provided on the inner wall of the fixing shell 202. The inner wall of the arc-shaped slide hole 207 is slidably connected with the arc-shaped slide column 206. The outer ends of the arc-shaped slide column 206 are fixedly connected with the inner side surface of the adjacent fixing plate 204. The inner side surface of the fixing plate 204 and the inner wall of the fixing shell 202 are fixedly connected with a spring 205. The spring 205 is sleeved on the outer surface of the arc-shaped slide column 206 to ensure that the upper and lower positions of the fixing shell 202 correspond to the slot 209 for plugging. The fixing shell 202 on the upper end of the polyethylene shell 1 is inserted into the lower end of the polyethylene shell 1 through manual operation. The fixing plate 204 is pressed against the slot 209 of the olefin shell 1. When the shell 202 is installed, the fixing plate 204 is subjected to an extrusion force. This extrusion force causes the fixing plate 204 to rotate a certain angle around the rotation axis 203. However, while the fixing plate 204 is rotating, the spring 1 205 is compressed. The compression of the spring 1 205 causes the arc-shaped sliding column 206 to slide into the arc-shaped sliding hole 207, thereby driving the fixing plate 204 to rotate around the rotation axis 203, providing an escape space for the installation shell 202 to be plugged into the slot 209.

The presence of the rubber head 31 reduces direct contact with the fixing plate 204, thereby improving the service life, and then the fixing plate 204 is fixed by the rubber head 31. 4 applies an extrusion force, which causes the fixed plate 204 to rotate around the rotating shaft 203 by a certain angle. However, while the fixed plate 204 is rotating, the spring 1 205 is compressed. The compression of the spring 1 205 causes the arc-shaped sliding column 206 to slide into the arc-shaped sliding hole 207, thereby driving the fixed plate 204 to rotate around the rotating shaft 203 until it is separated from the top wall of the slot 208, and then the polyethylene shell 1 at the upper end is pulled upward. When moving, the polyethylene shell 1 at the upper end drives the installation shell 202 to separate from the slot 209, so that the two polyethylene shells 1 are separated, thereby making the replacement of the zinc alloy sacrificial anode faster and more efficient, reducing the manpower and time costs required, and improving the overall flexibility;,

[0027] The release fixing mechanism 3 is arranged on the front side of the polyethylene shell 1 at the lower end. The release fixing mechanism 3 is installed in cooperation with the fixing mechanism 2. The release fixing mechanism 3 includes a rubber head 31, a fixing column 32, a sliding column 35 and a sliding hole 36. The fixing column 32 is respectively fixedly connected to the front and rear sides of the polyethylene shell 1 at the lower end. The interior of the fixing column 32 is provided with a sliding hole 36. The sliding hole 36 is connected to the adjacent slot 209. The inner wall of the sliding hole 36 is slidably connected with the sliding column 35. The inner side end of the sliding column 35 is provided with a rubber head 31. The rubber head 31 is connected to the adjacent fixed The outer side surface of the fixed plate 204 is installed in cooperation, and the release fixing mechanism 3 also includes a second spring 33 and a button 34. The buttons 34 are fixedly connected to the outer end of the sliding column 35. The inner side surface of the button 34 and the outer side surface of the adjacent fixing column 32 are fixedly connected with the second spring 33. The second spring 33 is sleeved on the outer side surface of the sliding column 35. When the active metal 4 needs to be replaced, the button 34 is pressed, and the button 34 compresses the second spring 33. While compressing the second spring 33, the sliding column 35 is driven to move into the sliding hole 36 until the rubber head 31 contacts the fixing plate 204 at the adjacent end;

[0028] Active metal 4: It is located inside the two polyethylene shells 1. The active metal 4 is usually made of zinc alloy. Using its characteristics as an active metal, it constitutes a zinc alloy sacrificial anode, thereby protecting the protected metal surface from corrosion. The left and right ends of the active metal 4 are both installed in conjunction with two vertically adjacent rubber strips 5, so that the two vertically adjacent rubber strips 5 are in contact with the outer surfaces of the left and right ends of the active metal 4, thereby improving the sealing between the connections, providing a more complete and continuous protective layer, and avoiding direct contact of the corrosive medium with the zinc alloy.

[0029] The working principle of a zinc alloy sacrificial anode structure provided by the utility model is as follows: first, an active metal 4 is placed inside the polyethylene shell 1 at the lower end, and it is ensured that the position and direction of the active metal 4 meet the design requirements and can be correctly connected with the polyethylene shell 1 at the upper end, and then the polyethylene shell 1 at the upper end is assembled with the polyethylene shell 1 at the lower end through manual operation, and then it is ensured that the upper and lower positions of the installation shell 202 and the slot 209 correspond to each other for plugging, and the installation shell 202 on the polyethylene shell 1 at the upper end is inserted into the slot 209 of the polyethylene shell 1 at the lower end through manual operation, and when the shell 202 is installed, the fixing plate 204 is subjected to an extrusion force, and this extrusion force causes the fixing plate 204 to rotate around the rotation axis 2 03 rotates a certain angle, while the fixing plate 204 rotates, the spring 1 205 is compressed, and the compression of the spring 1 205 causes the arc-shaped sliding column 206 to slide into the arc-shaped sliding hole 207, thereby driving the fixing plate 204 to rotate around the rotating shaft 203 as the center, providing an escape space for the installation shell 202 to be plugged into the slot 209. When inserted to a certain depth, the slot 208 will appear. At this time, the spring 1 205 releases the elastic energy storage, driving the fixing plate 204 and the arc-shaped sliding column 206 to rotate in the opposite direction around the rotating shaft 203 as the center, and rebound. During the rebound process, the top of the fixing plate 204 is engaged with the top wall of the slot 208, thereby fixing the upper and lower polyethylene shells 1, and also fixing the active metal 4, and making the two vertically adjacent The rubber strip 5 contacts the outer surfaces of the left and right ends of the active metal 4, and the mounting shell 202 also contacts the outer surface of the rubber pad 210, thereby improving the sealing between the connections, providing a more complete and continuous protective layer, avoiding direct contact of the corrosive medium with the zinc alloy, and reducing the vibration and external environment of the zinc alloy sacrificial anode or other components during use, thereby extending the service life of the device, and enabling rapid installation and improving work efficiency.

While compressing the spring 2 33, the slide column 35 is driven to move into the slide hole 36 until the rubber head 31 contacts the fixing plate 204 at the adjacent end. In order to reduce direct contact with the fixed plate 204 and improve service life, the rubber head 31 is used to apply an extrusion force to the fixed plate 204. This extrusion force causes the fixed plate 204 to rotate around the rotating shaft 203 by a certain angle. While the fixed plate 204 is rotating, the spring 1 205 is compressed. The compression of the spring 1 205 causes the arc-shaped sliding column 206 to slide into the arc-shaped sliding hole 207, thereby driving the fixed plate 204 to rotate around the rotating shaft 203 until it is separated from the top wall of the slot 208. Then, the polyethylene shell 1 at the upper end is pulled upward. When moving, the polyethylene shell 1 at the upper end drives the installation shell 202 to separate from the slot 209, so that the two polyethylene shells 1 are separated, thereby making the replacement of the zinc alloy sacrificial anode faster and more efficient.The required manpower and time costs will be reduced, improving overall flexibility.
