Description

Technical Field

[0001] This utility model relates to the field of metal corrosion protection technology, specifically to an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention. Background Technology

[0002] Cathodic protection is an effective means of preventing metal corrosion in dielectrics (such as seawater and soil), with sacrificial anode methods being particularly widely used. Aluminum alloy sacrificial anodes are continuously consumed during use, thus providing a protective current to the protected metal structure.

[0003] Chinese utility model patent CN222795733U discloses an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, including an anti-corrosion plate. The top of the anti-corrosion plate has a placement groove in which aluminum alloy is placed. Two support plates are fixedly connected to the top of the anti-corrosion plate, positioned on the left and right sides of the top of the support plates. A fixing plate is fixedly connected to the right side wall of the left support plate and to the left side wall of the right support plate. A motor is fixedly connected to the top of the fixing plate. This utility model uses the motor to rotate a second movable rod, which in turn moves a first movable rod. The first movable rod moves vertically along a limiting frame, causing a monitoring camera to continuously monitor the consumption of the aluminum alloy. If the aluminum alloy is consumed below the position of a contact sensor placed by a person, the contact sensor will trigger an alarm to alert the person.

[0004] Currently, assessing anode consumption relies heavily on periodic manual inspections and measurements, which cannot provide real-time, intuitive monitoring. When anodes are depleted and not replaced in time, protection fails, resulting in significant economic losses and safety hazards. Therefore, an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention is needed to address these issues. Utility Model Content

[0005] This invention provides an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, in order to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, comprising an anti-corrosion plate, a mounting frame, and a controller. A fixing frame is mounted at a height near the left and right sides of the top of the anti-corrosion plate. A Hall sensor is fixedly mounted near the front end of the top right side of the anti-corrosion plate. An aluminum alloy sacrificial anode is disposed on the top of the anti-corrosion plate. Mounting grooves are formed on the left and right sides of the mounting frame near the front and rear ends. A sliding rod is fixedly mounted on the inner bottom wall of each of the mounting grooves. A slider is movably sleeved on the outer surface of each of the sliding rods. Adjustable pressure gas springs are fixedly mounted on the inner top wall of the mounting frame near the left and right sides. A clamping plate is fixedly connected to the bottom of two adjustable pressure gas springs. A magnet is fixedly mounted on the right side of the clamping plate near the front end. A multi-color LED audible and visual alarm light is fixedly mounted on the top of the mounting frame.

[0007] Furthermore, the left and right sides of the clamping plate are fixedly connected to the adjacent side of a plurality of sliders near the front and rear ends.

[0008] Furthermore, the magnet is located directly above the Hall sensor, and the Hall sensor and the magnet are arranged symmetrically.

[0009] Furthermore, during installation, the bottom of the mounting bracket near the left and right sides is close to the top of the anti-corrosion plate, and the top of the mounting bracket near the left and right sides is fixedly connected to the inside of the two fixing brackets by bolts.

[0010] Furthermore, the bottoms of the two adjustable pressure gas springs are fixedly connected to the top of the pressure plate near the left and right sides, respectively.

[0011] Furthermore, the tops of the plurality of sliding rods are respectively fixedly connected to the inner top walls of the plurality of mounting slots.

[0012] Furthermore, the clamping plates are located directly above the aluminum alloy sacrificial anode; and are all located outside the area of ​​the aluminum alloy sacrificial anode to avoid interference.

[0013] Furthermore, the multi-color LED audible and visual alarm light, slide bar, slider, pressure plate, Hall sensor, and magnet constitute an adjustable pressure gas spring inspection and protection device; the Hall sensor and the multi-color LED audible and visual alarm light are both connected to the controller via wires; the controller has a pre-written control program for receiving the voltage signal from the Hall sensor and controlling the multi-color LED audible and visual alarm light to display different colors and sounds according to the range of change of the signal value.

[0014] Compared with the prior art, this utility model provides an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, which has the following beneficial effects: 1. This aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, through the installation of an inspection and protection device, uses a Hall sensor and a magnetic block to convert the physical consumption of the anode into an electrical signal. A multi-color LED audible and visual alarm clearly indicates the remaining level, triggering a buzzer alarm when the anode is depleted, thus transforming the monitoring from "periodic inspection" to "real-time monitoring." A sliding rod and slider mechanism ensures smooth and linear pressure during the pressing process, preventing jamming. An adjustable pressure gas spring provides a constant and settable downward pressure, ensuring good contact without damaging the anode, adapting to various operating conditions. The entire monitoring process is fully automated, requiring no manual intervention, reducing maintenance costs and human error. Its simple structure and durability make it particularly suitable for long-term use in harsh industrial or marine environments. Attached Figure Description

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.

[0018] Please see Figure 1-2This utility model discloses an aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, including an anti-corrosion plate 4, a mounting frame 7, and a controller 6. Fixing frames 3 are installed at a height near the left and right sides of the top of the anti-corrosion plate 4. A Hall sensor 106 is fixedly installed near the front end of the top right side of the anti-corrosion plate 4. An aluminum alloy sacrificial anode 5 is provided on the top of the anti-corrosion plate 4. Mounting grooves 2 are provided on the left and right sides of the mounting frame 7 near the front and rear ends. Sliding rods 103 are fixedly installed on the inner bottom walls of multiple mounting grooves 2. Sliding blocks 104 are movably sleeved on the outer surfaces of multiple sliding rods 103. Adjustable pressure gas springs 101 are fixedly installed on the inner top wall of the mounting frame 7 near the left and right sides. A clamping plate 105 is fixedly connected to the bottom of two adjustable pressure gas springs 101. A magnet block 107 is fixedly installed on the right side of the clamping plate 105 near the front end. A multi-color LED audible and visual alarm light 102 is fixedly installed on the top of the mounting frame 7.

[0019] Specifically, the left and right sides of the clamping plate 105 are fixedly connected to the adjacent side of a plurality of sliders 104 near the front and rear ends.

[0020] Specifically, the magnet 107 is located directly above the Hall sensor 106, and the Hall sensor 106 and the magnet 107 are arranged symmetrically.

[0021] Specifically, during installation, the bottom of the mounting bracket 7 is close to the top of the anti-corrosion plate 4 near the left and right sides, and the top of the mounting bracket 7 is fixedly connected to the inside of the two fixing brackets 3 by bolts near the left and right sides.

[0022] In this implementation plan, Specifically, the bottoms of the two adjustable pressure gas springs 101 are fixedly connected to the top of the pressure plate 105 near the left and right sides, respectively.

[0023] Specifically, the tops of the multiple slide rods 103 are fixedly connected to the inner top walls of the multiple mounting slots 2.

[0024] Specifically, the clamping plate 105 is located directly above the aluminum alloy sacrificial anode 5; and is located outside the area of ​​the aluminum alloy sacrificial anode 5 to avoid interference.

[0025] Specifically, the multi-color LED audible and visual alarm light 102, slide bar 103, slider 104, pressure plate 105, Hall sensor 106, and magnet 107 constitute the adjustable pressure gas spring 101 inspection and protection device 1; the Hall sensor 106 and the multi-color LED audible and visual alarm light 102 are both connected to the controller 6 through wires; the controller 6 has a pre-written control program for receiving the voltage signal from the Hall sensor 106 and controlling the multi-color LED audible and visual alarm light 102 to display different colors and sounds according to the range of change of the signal value.

[0026] In the initial state (newly installed anode), the clamping plate 105 is pressed down by the gas spring, tightly adhering to the surface of the aluminum alloy sacrificial anode 5. At this time, the magnet 107 is furthest from the Hall sensor 106, and the magnetic field is weakest, so the Hall sensor 106 outputs an initial low voltage signal. The controller 6 recognizes this signal, and the multi-color LED audible and visual alarm light 102 emits a corresponding light (e.g., green), indicating sufficient anode. As the aluminum alloy sacrificial anode 5 is continuously consumed, its thickness decreases, and the clamping plate 105 moves downward under the continuous pressure of the gas spring, causing the magnet 107 to gradually approach the Hall sensor 106. The magnetic field strength sensed by the Hall sensor 106 increases linearly, and its output voltage signal also increases accordingly. When the voltage signal reaches the preset first threshold, the controller 6 determines that a certain amount of anode has been consumed, and the multi-color LED audible and visual alarm light 102 switches to the corresponding light (e.g., yellow) to provide a warning. When the voltage signal reaches the second preset higher threshold, the controller 6 determines that the anode is about to be depleted. The multi-color LED audible and visual alarm 102 switches to the corresponding light (e.g., red) and activates the built-in buzzer to emit a rapid sound, informing maintenance personnel that the aluminum alloy sacrificial anode 5 must be replaced immediately. To replace the aluminum alloy sacrificial anode 5, simply loosen the connecting bolts, lift the entire mounting bracket 7 upwards, replace the new anode, and re-secure the mounting bracket 7. The gas spring will automatically press the clamping plate 105 down onto the surface of the new anode, the system will reset, and a new round of monitoring will begin.

[0027] In summary, this aluminum alloy sacrificial anode for cathodic protection and corrosion prevention, through the installation of an inspection and protection device 1, and the cooperation of a Hall sensor 106 and a magnet 107, converts the physical consumption of the anode into an electrical signal. A multi-color LED audible and visual alarm 102 clearly indicates the remaining level, triggering a buzzer alarm when the anode is depleted, thus achieving a shift from "periodic inspection" to "real-time monitoring." The guide mechanism of the slide bar 103 and slider 104 ensures the smoothness and linearity of the pressing process of the clamping plate 105, preventing jamming. The adjustable pressure gas spring 101 provides a constant and settable downward pressure, ensuring good contact without damaging the anode, adapting to different operating conditions. The entire monitoring process is fully automated, requiring no manual intervention, reducing maintenance costs and human error. Its simple structure and durability make it particularly suitable for long-term use in harsh industrial or marine environments.
