Description

Technical Field

[0001] This utility model relates to the field of metal corrosion and protection technology, and in particular to an easy-to-install aluminum alloy sacrificial anode structure. Background Technology

[0002] The aluminum alloy sacrificial anode structure mainly consists of an anode body, a steel core, installation accessories, and optional cables. The anode body uses high-purity aluminum alloy as the base material and adds alloying elements such as zinc, indium, and tin to optimize electrochemical performance. The steel core is embedded inside the anode body to conduct current and serve as a connection carrier. Installation accessories include brackets, bolts, and clamps to fix the anode. The cable enables current transmission when the anode is far from the protected structure. The overall structure needs to meet the requirements of good conductivity, convenient installation, reliable connection, uniform anode dissolution, and long service life. Therefore, an easy-to-install aluminum alloy sacrificial anode structure is particularly needed.

[0003] However, existing aluminum alloy sacrificial anode structures are usually fixed by welding directly onto the body. This method is not only cumbersome, but also requires professional personnel with special welding equipment for on-site construction. Furthermore, the welding process can easily damage the anode body and the surface of the protected structure. At the same time, the anti-corrosion treatment of the welded joints is difficult, and long-term use can easily lead to corrosion and cracking. Subsequent maintenance and replacement also require destructive operations, which seriously affects construction efficiency and overall protection effect. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install aluminum alloy sacrificial anode structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install aluminum alloy sacrificial anode structure, comprising an aluminum anode, a connector fixedly connected to one side surface of the aluminum anode, a connection hole and a groove being provided on one side surface of the connector, and an installation mechanism being provided inside the connection hole; The mounting mechanism includes a circular insert block, which is inserted into the inner surface of the connecting hole. A rectangular groove and a circular hole are formed on one side surface of the circular insert block. A bearing is fixedly connected to the outer side of the circular insert block, and a spring is slidably connected to the inner side of the circular hole. A locking block is fixedly connected to one side surface of the spring. A rotating seat is fixedly connected to the outer side of the bearing. A rotating hole and a rotating groove are formed on one side surface of the rotating seat. A mounting plate is fixedly connected to one side surface of the rotating seat, and a mounting hole is formed on one side surface of the mounting plate.

[0006] Preferably, the mounting holes are provided in two identical sizes and are symmetrically distributed along the transverse central axis of the mounting plate, and the transverse central axis of the mounting plate is perpendicular to the vertical central axis of the rotating seat.

[0007] Preferably, the cross-section of the connector is designed in a "Z" shape, and two connectors of the same size are provided and symmetrically distributed along the transverse central axis of the aluminum anode. The grooves are provided in two sets of the same size, and each set has two grooves of the same size.

[0008] Preferably, the connecting hole is adapted to the size of the circular insert, and two rectangular slots of the same size are provided and symmetrically distributed along the transverse central axis of the circular insert, and the two rectangular slots are connected to the circular hole.

[0009] Preferably, the cross-section of the card block is designed in the shape of "⊿", the end of the card block near the spring is adapted to the size of the rectangular groove, and two card blocks of the same size are provided and symmetrically distributed along the transverse central axis of the spring.

[0010] Preferably, the spring is adapted to the size of the circular hole, and the bearing is adapted to the size of the rotating groove.

[0011] Preferably, the mounting mechanism has at least two of the same size, and the rotating hole is adapted to the size of the circular insert.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. No need to rely on professional welding equipment and technicians. Through the cooperation of circular inserts, springs and clips, a single person can manually fix the aluminum anode to the installation mechanism. Compared with traditional welding installation, the operation time is greatly reduced. It is especially suitable for scenarios with narrow space and inconvenient complex operations, such as next to buried pipelines and inside ship cabins. The connector adopts a "Z" shaped cross-section design, which can cleverly avoid protrusions or obstacles on the surface of the protected structure. At the same time, it reserves a reasonable current conduction gap between the anode and the structure. Compared with straight connectors, it has a stronger ability to adapt to complex structures. 2. The bearing on the outer side of the circular insert is precisely matched with the rotating groove of the rotating seat. After the aluminum anode is fixed, it can rotate freely around the circular insert, which can flexibly adapt to various installation environments. The two installation mechanisms are symmetrically distributed, which can evenly distribute the weight of the anode and external forces, reduce the load on a single connection point, and reduce the risk of structural fatigue during long-term use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 This utility model provides a technical solution: an easy-to-install aluminum alloy sacrificial anode structure, including an aluminum anode 1, a connector 2 fixedly connected to one side surface of the aluminum anode 1, a connection hole 3 and a groove 4 opened on one side surface of the connector 2, and an installation mechanism 5 provided inside the connection hole 3; The mounting mechanism 5 includes a circular insert 501, which is inserted into the inner surface of the connecting hole 3. A rectangular groove 502 and a circular hole 503 are formed on one side surface of the circular insert 501. A bearing 504 is fixedly connected to the outer side of the circular insert 501. A spring 505 is slidably connected to the inner side of the circular hole 503. A retaining block 506 is fixedly connected to one side surface of the spring 505. A rotating seat 507 is fixedly connected to the outer side of the bearing 504. A rotating hole 508 and a rotating groove 509 are formed on one side surface of the rotating seat 507. A mounting plate 510 is fixedly connected to one side surface of the rotating seat 507. A mounting hole 511 is formed on one side surface of the mounting plate 510. The circular insert 501 and the rectangular groove 502 are connected to the connecting hole 3. The arrangement of groove 502, circular hole 503, bearing 504, spring 505, and locking block 506 allows for the following operation: During use, the connector 2 on one side of the aluminum anode 1 is aligned with the circular insert 501 of the mounting mechanism 5. The aluminum anode 1 is pushed to insert the circular insert 501 into the connecting hole 3. During insertion, the groove 4 presses against the triangular inclined surface of the locking block 506, forcing the two locking blocks 506 to compress the spring 505 along the rectangular groove 502. When the circular insert 501 is fully inserted into the connecting hole 3, the locking block 506 pops out under the elastic force of the spring 505 inside the circular hole 503. Then, the bearing 504 on the outside of the circular insert 501 rotates, causing the two locking blocks 506 to misalign with the two grooves 4. This eliminates the need for specialized welding equipment and technicians, significantly reducing operation time compared to traditional welding installation.

[0017] Furthermore, the mounting holes 511 are provided with two of the same size and are symmetrically distributed along the transverse central axis of the mounting plate 510. The transverse central axis of the mounting plate 510 is perpendicular to the vertical central axis of the rotating seat 507. With the installation of the mounting holes 511, the two mounting holes 511 of the same size can be used to fit fasteners such as bolts and expansion screws of conventional specifications. Installation can be completed with only conventional tools, reducing the dependence on on-site tools.

[0018] Furthermore, the cross-section of the connector 2 is designed in a "Z" shape. There are two connectors of the same size, which are symmetrically distributed along the transverse central axis of the aluminum anode 1. There are two sets of grooves of the same size, and each set has two of the same size. With the setting of the grooves 4, when the circular insert 501 is fully inserted into the connecting hole 3, the locking block 506 and the connector 2 form an initial mechanical lock. When the aluminum anode 1 is rotated and the locking block 506 is misaligned with the groove 4, the side wall of the groove 4 can prevent the locking block 506 from retracting, forming a secondary anti-disengagement mechanism, which greatly improves the stability of the mechanism.

[0019] Furthermore, the connecting hole 3 is adapted to the size of the circular insert 501. Two rectangular slots 502 of the same size are provided and are symmetrically distributed along the transverse central axis of the circular insert 501. The two rectangular slots 502 are connected to the circular hole 503. Through the setting of the rectangular slots 502 and the circular hole 503, in use, the rectangular slots 502 are connected to the circular hole 503. The circular hole 503 can provide a fixed installation space for the spring 505, while the rectangular slots 502 limit the movement direction of the locking block 506, which greatly improves the stability of the mechanism.

[0020] Furthermore, the cross-section of the locking block 506 is designed in the shape of a "⊿". The end of the locking block 506 near the spring 505 is adapted to the size of the rectangular groove 502. Two locking blocks 506 of the same size are provided and are symmetrically distributed along the transverse central axis of the spring 505. Through the setting of the locking block 506 and the rectangular groove 502, the rectangular groove 502 can provide the locking block 506 with room to move during use, ensuring that the locking block 506 will not cause obstruction when the circular insert 501 is inserted into the connecting hole 3.

[0021] Furthermore, the dimensions of the spring 505 and the circular hole 503 are matched, and the dimensions of the bearing 504 and the rotating groove 509 are matched. Through the setting of the spring 505 and the circular hole 503, the circular hole 503 can limit the spring 505 during use, ensuring that the spring 505 is not easily deformed.

[0022] Furthermore, the mounting mechanism 5 is provided with at least two rotating holes 508 of the same size that are adapted to the size of the circular insert 501. Through the provision of the rotating holes 508 and the circular insert 501, the compatibility between the rotating holes 508 and the circular insert 501 can form a radial constraint on the circular insert 501 during use, preventing the circular insert 501 from shifting laterally during use and reducing the failure rate of the mechanism.

[0023] Working principle: During installation, the mounting mechanism 5 is first fixed to the protected metal structure through the mounting holes 511 of the mounting plate 510. Then, the connector 2 on one side of the aluminum anode 1 is aligned with the circular insert 501 of the mounting mechanism 5. The aluminum anode 1 is pushed so that the circular insert 501 is inserted into the connecting hole 3. During the insertion process, the groove 4 will squeeze the triangular inclined surface of the locking block 506, forcing the two locking blocks 506 to compress the spring 505 along the rectangular groove 502. When the circular insert 501 is fully inserted into the connecting hole 3, the locking block 506 pops out under the elastic force of the spring 505. Then, the bearing 504 on the outside of the circular insert 501 is used to rotate, so that the two locking blocks 506 and the two grooves 4 are misaligned. When disassembling, simply press the locking block 506 in the groove 4 without damaging the structure, which is convenient for replacement and maintenance. This completes the use process of an easy-to-install aluminum alloy sacrificial anode structure.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
