Detailed Description of the Invention

[0022] Refer to Figures 1 - 4, a corrosion-resistant and easy-to-clean oxygen evolution titanium electrode provided by the utility model: includes a fixed frame 1, two mounting rods 2 are fixed on the upper surface of the fixed frame 1, an electrode body 3 is installed inside the fixed frame 1, two groups of clamping grooves 4 are symmetrically opened on the inner wall of the fixed frame 1, and clamping blocks 5 fixed to the electrode body 3 are clamped and connected inside the two groups of clamping grooves 4. An anti-corrosion coating 6 is coated on the outer surface of the electrode body 3. Two threaded holes 7 are opened at both ends of the electrode body 3. Two fixing bolts 8 threadedly connected to the threaded holes 7 are installed at both ends of the fixed frame 1. Through the clamping grooves 4 opened in the fixed frame 1, it is convenient to connect the electrode body 3 and the fixed frame 1. Tighten the fixing bolts 8 on the fixed frame 1 to fix the electrode body 3 and prevent it from falling off. Through the anti-corrosion coating 6 applied on the electrode body 3, it can achieve a good anti-corrosion effect, thereby improving the service life of the electrode.

[0023] As a further implementation of the above technical solution: two limiting grooves 9 are opened in the vertical direction inside the fixed frame 1, and two stepping motors 10 are fixed on the upper surface of the fixed frame 1 by bolts. Through the two stepping motors 10 provided, the cleaning mechanism can be driven synchronously to clean the outer surface of the electrode body 3.

[0024] As a further implementation of the above technical solution: the power output shafts of the two stepping motors 10 penetrate the fixed frame 1 and are fixed with a lead screw 11. A connecting block 12 that is threadedly connected to the outer surface of the lead screw 11 and slidably connected to the limiting groove 9 is provided. Through the cooperation of the limiting groove 9 to play a guiding role, the rotation of the lead screw 11 drives the vertically moving connecting block 12 that is threadedly connected.

[0025] During specific implementation, before using the corrosion-resistant and easy-to-clean oxygen evolution titanium electrode, first place the fixed frame 1 in a suitable position, and fix the mounting rods 2 and external equipment through bolts to complete the installation. Through the clamping grooves 4 opened in the fixed frame 1, align the clamping blocks 5 with the clamping grooves 4, and push the electrode body 3 in the horizontal direction to connect the electrode body 3 and the fixed frame 1. After the connection is completed, the fixing bolts 8 on the fixed frame 1 can be tightened to connect the fixing bolts 8 and the threaded holes 7 to fix the electrode body 3 and prevent it from falling off. Moreover, the electrode body 3 can be disassembled subsequently for easy replacement. Through the anti-corrosion coating 6 applied on the electrode body 3, it can achieve a good anti-corrosion effect, thereby improving the service life of the electrode.

[0026] As a further implementation of the above technical solution: a fixed bearing 13 embedded in the inner wall of the limiting groove 9 is sleeved on the lower surface of the lead screw 11. The lead screw 11 and the stepping motor 10 form a rotating structure. Through the fixed bearing 13 provided, the smooth rotation of the lead screw 11 can be ensured.

An activity plate 17 is fixed to the end of the limiting plate 16.

The side wall of the cleaning brush 18 is closely attached to the outer surface of the electrode body 3. By moving the cleaning brush 18, the impurities adhered to the surface of the electrode body 3 can be cleaned.

[0030] During specific implementation, when the electrode needs to be cleaned, the staff can place the electrode in clean water. The stepping motor 10 drives the lead screw 11 to rotate. With the cooperation of the limiting groove 9, a guiding effect is achieved, so that the rotation of the lead screw 11 drives the connecting block 12 connected by threads to move vertically. The provided fixed bearing 13 can ensure the smooth rotation of the lead screw 11, thereby driving the cleaning member 14 to move vertically and synchronously driving the cleaning brush 18 to move to clean the impurities adhered to the surface of the electrode body 3. And under the action of the elasticity of the spring 15 itself, the limiting plate 16 will be pushed to move, so that the activity plate 17 drives the cleaning brush 18 to better contact the surface of the electrode body 3, thereby improving the cleaning effect and improving the practicability.
