Description

[Detailed description of the invention] This invention is a continuous water flow electrical system for electrically insulating the electrical control unit from the supply side or the discharge side when performing electrical processing such as conditioning water by electrolysis. This relates to an insulation mechanism.

As this type of insulating element, one using a siphon tube is known.

Although this is effective in principle, it has the disadvantage that the electrical insulation properties deteriorate when limescale accumulates during long-term use.

In particular, when the amount of water supplied is large, it becomes unusable in a relatively short period of time.

Therefore, a water diversion member is used to create a tank that rotates the continuously supplied water stream and continuously supplies water to the chambers partitioned by partition walls, while also being completely electrically divided. However, a mechanism was proposed earlier that could prevent practical problems (breakdown of electrical insulation due to limescale).

However, the problem with this) is that if a failure occurs in the opening/closing operation of the on-off valves installed in each chamber, electrical continuity between the electrical control section and the supply or discharge side of the above mechanism is immediately established. It becomes.

This idea was developed in view of the above circumstances, and aims to provide a continuous water flow electrical insulation mechanism that allows water to be discharged from a partitioned room without the need for moving parts such as the above-mentioned on-off valve. It is.

This invention will be explained in detail below based on the illustrated embodiments.

In the figure, reference numeral 1 is divided in the circumferential direction with partition walls 1a in the radial direction.

It is a fan-shaped rotating tank unit, and has a rotating shaft 2 tilted at a predetermined angle in the center, and is attached to this rotating shaft 2.

As is clear from the figure, the above-mentioned unit is constructed in a shape that allows all the water inside the unit to be expelled when the outer peripheral wall is below the rotating shaft 2. A gap 3 is formed between the unit 1 and the unit 1.

A water supply port 4 is opened above the unit 1 on the upper side of the rotating shaft 2 .

Further, the rotating shaft 2 is hollow and allows air to flow in through a lower end opening 2a and to be discharged through an opening 2b provided on the upper side.A wind turbine blade 5 is provided at the upper end of the shaft.
is pivoted.

Pulleys 5a and 2c are provided on the upper ends of the windmill blades 5 and the rotating shaft 2, respectively, and pulleys 8b and 8C are provided on the shaft 8a of the motor 8 via belts 6 and 7.
It is now linked to.

In this case, a reduction gear mechanism 15 is interposed in the transmission system of the rotating shaft 2.

Further, a guide tube 9 is provided near the windmill blade 5 so that air can flow through the windmill blade 5 via the rotating shaft 2.

In addition, an overflow edge 10 is provided on the wall of the unit 1 formed in contact with the void 3, so that when excess water is supplied from the water supply port 4, the excess water is transferred to the water receiving tank 11 through the void 3. It is designed to be received in the drainage chamber 11a.

Furthermore, in the insulating chamber 11b of the water tank 11,
Unit 1 is drained.

In the unit 1, a watershed member 12 that straddles the partition wall is provided at the upper edge of the partition wall.

This watershed member 12 has a structure that is fixed to the partition wall 1a of one rotating tank unit 1, does not structurally contact the other rotating tank unit, and maintains an appropriate electrically insulating space.

For this reason, the partition wall 1a on the side to which the attachment is performed is constructed slightly higher.

The watershed member 12 itself has a structure in which weirs 12b are provided at both ends of a chevron-shaped watershed member 12a.

In addition, in the water receiving tank 11, two ring electrodes 13 are provided at the drain port 11C of the drain chamber 11a, and when water flows, they become electrically conductive with each other through water, and a detection mechanism that issues a signal. constitutes part of.

Further, an electrode 14 for detecting electric leakage is provided in the insulating chamber 11b.

In such a configuration, when the unit 1 is being rotated by the rotation of the rotating shaft 2, when water is supplied from the water supply port 4, the unit 1 is filled with water on this side, and there is also a gap between the units. When crossing the water, the watershed member 12 distributes the water.

When the unit 1 is below the rotating shaft 2, the walls of each unit are formed to be inclined so that water drains from the outer edge of the unit (in this embodiment, the more the unit 1 is inclined to the horizontal position, the more ), the water is in a naturally inclined state, and water is drained into the insulating chamber 11b.

Since there are no moving parts such as on-off valves, there is no risk of drainage failure.

In this embodiment, a leakage detection electrode is also provided in case of a leakage, so that it can be detected immediately.

Moreover, if the water supply from the water supply port 4 becomes excessive, water will enter the drain chamber 11a over the overflow edge 10, so that the electrode 1
With the function of 3, abnormalities can be detected.

In this embodiment, the rotary tank units are constructed separately, but several of them may be constructed integrally, or they may be attached to and detached from the rotary shaft.

As detailed above, this invention includes a rotating tank unit that is circumferentially divided with partition walls in the radial direction, and a watershed member that straddles the partition walls of the rotating tank unit is provided at the upper edge of the partition wall. , the rotary tank unit is configured to be rotated around an inclined axis, and a water supply port for supplying water to each unit is provided on the upper side of the inclined axis, and a water supply port for supplying water to each unit is provided on the lower side of the inclined axis. Since the shape of the tank of the unit is configured to allow drainage, the water is drained without going through a control valve, etc., so there is no risk of malfunction, and it has the practical effect of being able to operate while maintaining reliable electrical insulation at all times. I can play it.
