Description

Technical Field

[0001] The present invention relates to the technical field of cathodic protection of high-silicon cast iron, and specifically to a cathodic protection device for high-silicon cast iron. Background Technique

[0002] High-silicon cast iron is an alloy cast iron with special properties. High-silicon cast iron is usually melted in a cupola furnace or an electric furnace. During the melting process, the atmosphere and temperature in the furnace need to be strictly controlled to prevent the oxidation of alloy components and ensure the uniform melting of alloy elements. During casting, due to its poor fluidity, a higher pouring temperature and a suitable pouring speed are required. Metals are prone to electrochemical corrosion in an electrolyte environment (such as soil, seawater, etc.). This kind of corrosion is caused by the potential difference between different parts of the metal surface, resulting in the flow of current inside the metal, thereby accelerating the dissolution and damage of the metal. Cathodic protection is a method of inhibiting the metal corrosion reaction by providing electrons to the metal to be protected, making its electrode potential shift negatively to the immune region.

[0003] The patent application with the Chinese patent application number CN202322930624.0 discloses a cathodic protection device for high-silicon cast iron. Although this application realizes injecting water into the inside of the PVC pipe when the water flow passes through the PVC pipe exposed on the ground, it is convenient to use in a large soil resistivity environment, convenient to add water, and keep the high-silicon cast iron anode body moist. However, when this application is put into use, since the hollow tubular high-silicon cast iron anode is generally arranged underground, the overall fit of the device with the ground is not high, and then the hollow pipe is prone to loosen underground. The poor fixing effect of the anode may lead to a reduction in the contact area between it and the soil or electrolyte, thereby affecting the active surface area and current output ability of the anode. This problem needs to be improved. Summary of the Invention

The rotating connection block is rotatably connected to the middle of the positioning rotating frame. The driving arm plate can rotate in the middle of the positioning rotating frame through the rotating connection block.

[0013] According to the above technical solution, a pressure valve is arranged at the top inside the connecting pipe. The telescopic end of the electric telescopic rod penetrates through the top of the liquid pressing box and extends into the liquid pressing box and is fixedly connected with the top.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0018] 1. The good fit between the anode ring and the soil can significantly reduce the grounding resistance of the anode, thereby improving the efficiency of the cathodic protection system. The reduction of the grounding resistance helps the current to flow more smoothly through the soil, enabling the metal structure to be protected to obtain more sufficient cathodic protection.

[0019] 2. The good soil fit effect can reduce the displacement and inclination of the anode ring in the soil, thereby ensuring the stable contact between the anode and the surrounding environment and maintaining the continuous and effective operation of the cathodic protection system. When natural disasters occur, the good soil fit effect can reduce the impact of external forces on the anode ring and reduce the risk of anode damage, ensuring the stability and reliability of the cathodic protection system.

[0020] 3. When the humidity is moderate, the conductivity of the soil increases, which helps the current to flow more easily in the soil, thereby improving the current output capacity of the anode. This is crucial for the effect of the cathodic protection system because sufficient current output can ensure that the protected structure is sufficiently cathodically polarized, thereby slowing down or preventing corrosion.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0032] Example 1, please refer to Figures 1-4 , the present invention provides a technical solution: a high-silicon cast iron cathodic protection device, including a hollow tubular high-silicon cast iron 1, and further including a driving assembly 3. An anode ring 2 is fixedly connected to the outside of the hollow tubular high-silicon cast iron 1, and a water storage ring pipe 4 is fixedly connected to the outside of the anode ring 2.

[0033] Among them, the driving assembly 3 includes:

[0034] The bidirectional telescopic rod 301 is fixedly connected inside the anode ring 2. Both the left and right ends of the bidirectional telescopic rod 301 are provided with telescopic ends. The telescopic ends of the bidirectional telescopic rod 301 are fixedly connected to the first moving extrusion frame 302. A squeezing arm plate 303 is rotatably connected to the middle of the first moving extrusion frame 302. A second moving extrusion frame 304 is rotatably connected to the side of the squeezing arm plate 303 away from the first moving extrusion frame 302. A driving arm plate 305 is fixedly connected to the top of the second moving extrusion frame 304. A soil fixing plug 306 is fixedly connected to the side of the driving arm plate 305 away from the hollow tubular high-silicon cast iron 1. Positioning and rotating frames 307 are fixedly connected to both the left and right sides of the anode ring 2. A rotating connection block 308 is fixedly connected to the side of the driving arm plate 305 close to the water storage ring pipe 4. When the first moving extrusion frame 302 pushes the squeezing arm plate 303, the second moving extrusion frame 304 can be pushed to drive the driving arm plate 305 to rotate.

[0035] The telescopic ends of the bidirectional telescopic rod 301 penetrate through the inner wall of the water storage ring pipe 4 and extend to the outside of the water storage ring pipe 4 and are fixedly connected to the first moving extrusion frame 302. The rotating connection block 308 is rotatably connected to the middle of the positioning and rotating frame 307.

At this time, the driving arm plate 305 rotates outward in the positioning and rotating frame 307 outside the anode ring 2, so that the soil fixing plug 306 on the driving arm plate 305 can be inserted into the soil, making the device fit more closely with the soil.
