FIGS. 1 and 2 show a conventional anti-corrosion electrode device. In the figure, 1 indicates a water storage tank and 2 indicates a corrosion protection electrode. To explain the detailed structure of the anti-corrosion electrode 2, 3 is an electrode rod, and 4 is fitted into the part of the electrode rod 3 near the water storage tank 1 in order to apply a uniform current to the can body of the water storage tank 1 and obtain a uniform anti-corrosion effect. The insulating tube 5 is a support insulator made of a material that is difficult to dissolve and supports the electrode rod 3, and the electrode rod 3 is supported by the support insulator 5 by press-fitting or insert molding. There is. Reference numeral 6 denotes a mounting fitting for attaching the anticorrosive electrode 2 to the water storage tank 1, and supports the supporting insulator 5 that supports the electrode rod 3. The mounting bracket 6 is provided with a hexagonal head 7 for tightening and a male screw 8 for tightening. 9 is a lead wire.
The anti-corrosion electrode 2 has the above structure. 10 is a female screw provided in the water storage tank 1, and 11 and 12 are gaskets. With the above structure, the anti-corrosion electrode 2 is fitted with a packing 11 in the mounting hole 1a of the water tank 1.

さで構成されている。 However, the support insulator 5 that supports the electrode rod 3
As mentioned above, it must be made of a material that is difficult to dissolve. If the support insulator 5 is poor in solubility, the interface with the electrode rod 3, that is, the support part formed by press-fitting, etc., will melt and cannot be supported. Generally, such supporting insulator 5 is made of a molded mixture of glass and mica,
Since it is relatively expensive, it is constructed with the minimum necessary length.

難かつた。 However, in order to achieve uniform and effective corrosion protection, it is necessary to ensure appropriate dimensions for each of the above-mentioned parts, so in the end, the electrode rod 3 is lengthened and a part of it is covered with an insulating tube 4 to obtain the predetermined length of the electrode rod. I was trying to get the exposed part. However, this electrode rod 3 is also made of a metal that is difficult to melt and corrode (generally titanium plated with platinum), so it is not cheap at all, and the cost is low when looking at the anti-corrosion structure as a whole. It was difficult to say that it was.

An object of the present invention is to provide a corrosion-proof electrode mounting structure for a tank that is shortened and advantageous in cost.
