Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an electric screen generator for generating an electric screen for restricting swimming of seafood.

[Conventional technology]

Generally, this kind of electric screen generator has a structure as shown in FIG. 3, for example.

That is, a plurality of electrode rods (1a) in the vertical direction are arranged at substantially equal intervals, and the electrode rods (1a) are electrically connected to each other to form a first electrode row (2a). Multiple electrode rods (1
b) and (1c) using the second electrode row (2b) and the third electrode row (2c)
Respectively, and each of the electrode rows (2a) to (2c) is arranged in parallel to each other in water, and is arranged between the first and second electrode rows (2a) and (2b) and between the first and third electrode rows (1a). ) And (1c)
By connecting (3) and (4), different potentials are applied to the electrode arrays (1a) to (1c).

Therefore, an electric field based on the potential difference, that is, an electric screen is formed between the electrode rows (1a) and (1b) and between the electrode rows (1b) and (1c).

When seafood invades such an electric screen, the seafood is electrically stimulated and shows a surprising reaction when the electric field strength is low, and as the electric field strength increases, a slight numbness, paralysis or even paralysis occurs. It shows a strong electric shock reaction such as asphyxia, cannot swim through the electric screen, and can block the swimming of seafood.

Here, if the electric field strengths of the electric screens between the electrode rows (2a) and (2b) and between the electrode rows (2b) and (2c) are made different, seafood such as large fish and small fish can be obtained. Regardless of the size of
The swimming can be reliably blocked, and damage to the seafood caused by electrical stimulation can be prevented.

[Problems to be solved by the device]

By the way, when forming the electric screen as described above in the actual sea area, how to construct a plurality of electrode rows (2a) ~ (2c) at low cost and easily is a major problem,
Conventionally, the electric screen generator is configured based on the tide difference and water depth, the length of the electric screen, etc., which is not only expensive but also lacks versatility, and the installation work depends on the work on the seabed. There is a disadvantage in that a large proportion of the work is done, a heavy burden is placed on the operator, and the risk is high.

The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide an electric screen generator capable of constructing an electric screen having a desired length and height easily and at low cost. It is what

[Means for Solving the Problems]

Then, a required number of block units supporting a plurality of electrode rods are tandemly connected to connect each of the block joints with a connecting line, whereby an electrode array having a desired length can be formed, and a desired length can be obtained. It makes it possible to form an electric screen.

Here, the tide level difference and the water depth can be easily dealt with by simply changing the length of the electrode rod of each unit.
