[0038] See also Figure 1 、 Figure 2 and Figure 3The present invention provides a cathodic protection rust-proof ring grid box 100 based on electrochemical reaction, comprising a ring grid box 100 and an electrochemical component, wherein the electrochemical component comprises a battery 200 and a rust-proof component 300. The rust-proof component 300 comprises a rust-proof housing 310, an electrolyte solution, and an anode electrode 330. The electrolyte solution and the anode electrode 330 are disposed within the rust-proof housing 310, and the electrolyte solution contacts the anode electrode 330 and the rust-proof housing 310. The anode electrode 330 is electrically connected to the positive electrode of the battery 200. The rust-proof housing 310 is conductive and electrically connected to the negative electrode of the battery 200 and the ring grid box 100. The activity of the anode electrode 330 is higher than that of the rust-proof housing 310.

[0039] The rust-proof shell 310 contains an electrolyte solution. The battery 200 energizes the rust-proof shell 310 and the anode electrode 330 to form an electrolytic cell. Based on the cathodic protection method of the sacrificial anode with an external power supply in the electrochemical protection method, the anode electrode 330 undergoes an oxidation reaction to lose electrons, and a reduction reaction occurs at the rust-proof shell 310 to gain electrons. The electrons can be transferred to the ring grid box 100, and the ring grid box 100 is prevented from forming a corrosion cell 200 by replenishing the charge, thereby achieving the rust-proof effect.

[0040] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 The rust-proof housing 310 is a tin box, comprising a body and a lid. The lid is hinged to the body on one side. The body is provided with a chamber with an open top, in which the electrolyte solution and the anode electrode 330 are located. The lid can be opened to cover the open end of the chamber. A sealing ring is provided at the junction of the body and lid to ensure a seal between the two. After the lid is attached to the body, it is locked with a lock to prevent leakage of the electrolyte solution during transportation.

[0041] In some embodiments, see Figure 1 and Figure 3 The rust-proof component 300 further includes a sponge 320, and the electrolyte solution is adsorbed in the sponge 320. The sponge 320 can absorb the electrolyte solution to prevent leakage of the electrolyte solution during transportation and movement.

[0042] In some embodiments, see Figure 1 and Figure 3 The anode electrode 330 is disposed above the sponge 320. The anode electrode 330 presses the sponge 320 to limit the movement of the sponge 320. The anode electrode 330 is disposed at the top, which facilitates timely replacement of the anode electrode 330.

[0043] In some embodiments, see Figure 1 、 Figure 2 and Figure 6The cathodic protection and rust-proof ring network box 100 based on electrochemical reaction also includes a solar photovoltaic panel 210, a wind turbine 220, and a wind-solar hybrid controller 230.

The wind-solar hybrid controller 230 is located in the distribution box 111 in the ring network box 100, and the wind-solar hybrid controller 230 is electrically connected to the battery 200. The installation of the solar photovoltaic panel and the wind turbine 220 can effectively utilize solar energy and wind energy for power generation, thereby saving energy. The excess electricity generated by the solar photovoltaic panel and the wind turbine 220 is stored by the lead-acid battery 200 to provide working power when there is no power input, thereby ensuring the long-term and effective operation of the system.

[0044] In some embodiments, see Figure 1 and Figure 6 The solar photovoltaic panel 210 is installed on top of the ring grid box 100, which can improve the utilization of the top space of the ring grid box 100. Two solar photovoltaic panels 210 are provided, connected at the middle. The two solar photovoltaic panels 210 are gradually tilted downward away from the middle, which can increase the illuminated area of the solar photovoltaic panels 210. The tilted solar photovoltaic panels 210 can reduce water and dust accumulation. The wind turbine 220 is installed on one side of the ring grid box 100 and is mounted on a wind tower 221. The wind turbine 220 is connected to the wind-solar hybrid controller 230 via pre-buried conduit.

[0045] In some embodiments, see Figure 1 and Figure 3 The electrolyte solution is NaCl solution. NaCl solution is easy to prepare and has low cost.

[0046] In some embodiments, see Figure 1 and Figure 3 Anode electrode 330 is made of aluminum or zinc. Aluminum and zinc are highly active in the periodic table and are readily available at a low cost. Rust-proof housing 310 is made of iron, and aluminum and zinc are more active than iron. When battery 200 energizes rust-proof housing 310 and anode electrode 330 to form an electrolytic cell, an oxidation reaction occurs at anode electrode 330, which loses electrons. A reduction reaction occurs at rust-proof housing 310, which then gains electrons, causing anode electrode 330 to corrode and consume.

[0047] In some embodiments, see Figure 1 and Figure 7The ring main unit 100 includes a housing 110 and a base 120. The housing 110 is connected to the base 120, and the base 120 is electrically connected to the rust-proof housing 310. The base 120 is a channel steel base 120, and the housing 110 is welded to the channel steel base 120, which is strong and durable. The rust-proof housing 310 is connected to the exposed metal part of the channel steel base 120 through copper wire.

[0048] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 The rust-proof component 300 also includes a fixing plate 340. The fixing plate 340 is made of an insulating material. The fixing plate 340 is arranged in the rust-proof shell 310. The anode electrode 330 is installed on the fixing plate 340. The fixing plate 340 is used to fix the anode electrode 330, thereby allowing the anode electrode 330 to be spaced apart from the rust-proof shell 310. The anode electrode 330 is in the shape of a plate and is fixed to the fixing plate 340 on the side close to the sponge 320. A connecting hole is provided on the anode electrode 330, and a threaded hole is provided on the fixing plate 340. A bolt is passed through the connecting hole and screwed into the threaded hole. The anode electrode 330 is fixed to the fixing plate 340 by the bolt, which is easy to assemble and disassemble and has a stable connection. The fixing plate 340 is provided to prevent the anode electrode 330 from contacting the rust-proof shell 310 and causing a short circuit.

[0049] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 The fixing plate 340 is provided with a mounting groove 341, and the anode electrode 330 is at least partially located in the mounting groove 341. By providing the mounting groove 341 to limit the installation of the anode electrode 330, the edge of the anode electrode 330 is prevented from contacting the rust-proof shell 310 and causing a short circuit.

[0050] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 The fixing plate 340 is provided with a handle 342. When the anode electrode 330 needs to be replaced, the handle 342 can be removed to remove the fixing plate 340 and the anode electrode 330 together. The fixing plate 340 is provided with a plurality of through holes 343 to facilitate the complete immersion of the electrolyte solution in the anode electrode 330 and to facilitate the removal of the fixing plate 340 from the rust-proof housing 310.

[0051] The working principle of the cathodic protection anti-rust ring network box 100 based on electrochemical reaction in the embodiment of the present application is as follows:

[0052] The solar photovoltaic panel 210 uses solar energy to generate electricity and stores it in the battery 200. The wind turbine 220 uses wind energy to generate electricity and stores it in the battery 200. The battery 200 energizes the rust-proof shell 310 and the anode electrode 330 to form an electrolytic cell. The anode electrode 330 undergoes an oxidation reaction to lose electrons, and a reduction reaction occurs at the rust-proof shell 310 to gain electrons. The electrons can be transferred to the ring grid box 100, and the ring grid box 100 is prevented from forming a corrosion cell 200 by replenishing the charge, thereby achieving the rust-proof effect.
