Replaceable sacrificial anode device

Abstract

This utility model discloses a replaceable sacrificial anode device, including a mounting frame and two lead blocks. Each lead block is connected to an external wiring connection. A groove is provided in the center of each lead block, the cross-section of which is the same as the cross-section of the sacrificial anode block. One lead block is fixedly connected to the mounting frame, while a shrinkage assembly is provided between the other lead block and the mounting frame. The shrinkage assembly includes a sleeve and a connecting rod. The lead block moves by the movable engagement of the sleeve and the connecting rod, enabling rapid insertion of the sacrificial anode block. Furthermore, the groove cross-section of the lead block matches the anode block, maximizing the contact area and ensuring stable conductivity. Simultaneously, the compression of the return spring can be released by unscrewing a bolt, pushing the movable lead block to ensure contact between the lead block and the sacrificial anode block, maintaining pressure on the sacrificial anode block, and ensuring stable contact resistance.

Description

Technical Field

[0001] This utility model belongs to the field of sacrificial anode installation technology, and particularly relates to a replaceable sacrificial anode device. Background Technology

[0002] Sacrificial anodes are a metal protection technology based on the principle of electrochemical corrosion, which protects other metal structures from corrosion by sacrificing the anode itself. They are widely used in energy, transportation, marine engineering, and other fields.

[0003] To maximize the contact area between the sacrificial anode and the connection point, it is usually fixed by welding or bolting. However, this fixing method is cumbersome and cannot be replaced quickly, which affects the protection work of the protected end. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A replaceable sacrificial anode device includes: a mounting frame and two lead blocks, the lead blocks being connected to external wiring, a groove being provided in the middle of the lead blocks, the groove having the same cross-section as the sacrificial anode block, one of the lead blocks being fixedly connected to the mounting frame, and a shrinkage assembly being provided between the other lead block and the mounting frame;

[0006] The shrinking assembly includes a sleeve and a connecting rod. The connecting rod is fixedly connected to the mounting bracket. One end of the sleeve is movably sleeved on the surface of the connecting rod, and the other end of the sleeve is fixedly connected to a corresponding guide block.

[0007] As a preferred embodiment of the above technical solution, a limiting rod is provided at one end of the connecting rod, a return spring is fixedly connected between one end of the limiting rod and the sleeve, a limiting plate is sleeved at the end of the limiting rod, and both ends of the limiting plate are fixedly connected to the sleeve.

[0008] As a preferred embodiment of the above technical solution, the limiting rod has a polygonal cross-section, and the limiting plate insertion point matches it.

[0009] As a preferred embodiment of the above technical solution, a bolt is threaded onto the surface of the sleeve, and one end of the bolt is in contact with the surface of the limiting rod to rub and fix the sleeve.

[0010] As a preferred embodiment of the above technical solution, a sealing ring is provided inside the sleeve, and the sealing ring is fitted with the surface of the connecting rod to seal the sleeve.

[0011] The beneficial effects of this utility model are as follows:

[0012] The movable connection between the sleeve and the connecting rod allows the lead block to move, enabling the rapid insertion of the sacrificial anode block. The groove cross-section of the lead block matches the anode block, maximizing the contact area and ensuring stable conductivity. Meanwhile, the compression of the return spring can be released by unscrewing the bolt, which can push the movable lead block to move, ensuring contact between the lead block and the sacrificial anode block, maintaining the pressure on the sacrificial anode block, and ensuring stable contact resistance.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0018] Figures 1-3 The replaceable sacrificial anode device includes: a mounting frame 10 and two lead blocks 20. The lead blocks 20 are connected to external lines. A groove 21 is provided in the middle of the lead block 20. The cross-section of the groove 21 is the same as that of the sacrificial anode block 40. One of the lead blocks 20 is fixedly connected to the mounting frame 10, and a shrinkage component 30 is provided between the other lead block 20 and the mounting frame 10.

[0019] The shrinking assembly 30 includes a sleeve 31 and a connecting rod 32. The connecting rod 32 is fixedly connected to the mounting bracket 10. One end of the sleeve 31 is movably sleeved on the surface of the connecting rod 32, and the other end of the sleeve 31 is fixedly connected to the corresponding connecting block 20.

[0020] The sleeve 31 is provided with a sealing ring 37 inside, and the sealing ring 37 is attached to the surface of the connecting rod 32 to seal the sleeve 31.

[0021] The movable connection between the sleeve 31 and the connecting rod 32 allows the lead block 20 to move, enabling the rapid insertion of the sacrificial anode block 40. Furthermore, the cross-section of the groove 21 of the lead block 20 matches that of the sacrificial anode block 40, maximizing the contact area and ensuring stable conductivity.

[0022] Figure 2 In the process, a limiting rod 33 is provided at one end of the connecting rod 32, and a return spring 34 is fixedly connected between one end of the limiting rod 33 and the sleeve 31. The return spring 34 is in a compressed state, and a limiting plate 35 is sleeved on the end of the limiting rod 33. Both ends of the limiting plate 35 are fixedly connected to the sleeve 31.

[0023] The limiting rod 33 has a polygonal cross-section, and the limiting plate 35 is inserted into it to match.

[0024] The compression of the return spring 34 can be released by unscrewing the bolt 36, which can push the movable contact block 20 to move, ensuring contact between the contact block 20 and the sacrificial anode block 40, maintaining the pressure on the sacrificial anode block 40, and ensuring stable contact resistance.

[0025] Figures 1-3 In the sleeve 31, a bolt 36 is threadedly inserted into the surface of the sleeve 31. One end of the bolt 36 is attached to the surface of the limiting rod 33 to rub and fix the sleeve 31.

[0026] Bolt 36 can fix sleeve 31, preventing sacrificial anode from shaking and causing return spring 34 to be repeatedly squeezed due to other factors during long-term operation, thus extending the service life of return spring 34.

[0027] Working principle: When the sacrificial anode block 40 needs to be replaced, rotate the bolt 36 counterclockwise to release the lock between the sleeve 31 and the limiting rod 33. This pushes the sleeve 31 back along the connecting rod 32, causing the return spring 34 to continue to compress. The limiting plate 35 restricts the rotation of the sleeve 31 through the polygonal limiting rod 33. The movable guide block 20 moves with the sleeve 31 and separates from the anode block, allowing the corroded and worn old anode to be removed. Then, the sacrificial anode block 40 is inserted into the groove 21 of the bottom-fixed guide block 20. After releasing the sleeve 31, the return spring 34 resets and moves the sleeve 31 back to its original position. When the movable contact block 20 is activated, it can automatically be fitted onto the sacrificial anode block 40. The elastic force generated by the return spring 34 is transmitted to the movable contact block 20 through the sleeve 31, tightly clamping the anode block between the two contact blocks 20 to ensure good conductive contact. To avoid reducing the performance of the return spring 34 due to prolonged use, the bolt 36 can be temporarily fixed. After a certain period of time, the bolt 36 can be rotated to disconnect the sleeve 31. The return spring 34 continues to release elastic force, pushing the movable contact block 20 to move slowly, maintaining the pressure on the sacrificial anode block 40 and ensuring stable contact resistance.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
