JP3614909B2 - Ultrasonic fishnet - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to an ultrasonic fishnet in which an ultrasonic transducer is bonded to a lattice substrate so that oysters, algae, and the like do not adhere to a part of the fishnet.
[0002]
[Prior art]
Conventionally, a fixed net that surrounds the coast with a net, floats at the top of the net, floats at the bottom, and sinks to the bottom of the sea with a weight attached to the bottom is placed and bred with fish such as sea bream. ing.
[0003]
By the way, oysters and seaweed are cheap on things put in the sea, but especially these oysters and seaweed are cheap on things 2 to 3 meters from the sea level.
[0004]
Therefore, oysters and algae are also cheaply attached to the stationary net, and the oysters and algae adhere to the part 2 to 3 meters below the sea surface with a width of several meters, and the mesh is between 1 month at the earliest time and 2 to 3 months at the earliest. Is about to be blocked.
[0005]
Here, fish such as hamachi travel around the sea surface part, but there is a problem that the fish near the sea surface is choked due to the lack of oxygen in the net when the mesh of the net near the sea surface is blocked.
[0006]
In order to solve this problem, as shown in FIG. 3, the present applicant passes a rope 2 containing a conductive wire through a cylindrical ceramic piezoelectric vibrator 1, and passes the conductive wire through the piezoelectric vibrator 1. Each of which is connected to the inner electrode and the outer electrode, and the net 3 is formed by connecting the ropes between the piezoelectric vibrators, and the piezoelectric vibrator 1 is provided vertically or horizontally or vertically and horizontally in the mesh. An ultrasonic fishnet covering at least the periphery of the piezoelectric vibrator 1 has been proposed (see Japanese Patent Application Laid-Open No. 64-30529).
[0007]
[Problems to be solved by the invention]
However, it takes time to form the cylindrical ceramic piezoelectric vibrator 1, and the work of forming the net 3 through the rope 2 on the cylindrical ceramic piezoelectric vibrator 1 is very complicated. There was a disadvantage of poor nature.
[0008]
[Means for solving problems]
The present invention comprises a lattice substrate in which a resin is formed in a lattice shape, and an ultrasonic vibrator bonded to one side of the lattice of the lattice substrate, and the lattice substrate is attached to a part of a fish net. It is.
[0009]
[Action]
According to the present invention, a resin can be formed in a lattice shape to form a lattice substrate, and an ultrasonic vibrator can be bonded to one side of each lattice of the lattice substrate so that it can be easily manufactured. Further, since this lattice substrate can be easily assembled to a part of the fish net, the assembly to the fish net can be greatly simplified.
[0010]
【Example】
FIG. 1 is a plan view of an ultrasonic fishnet according to an embodiment of the present invention, and a lattice substrate 4 is formed by forming a resin in a lattice shape so as to correspond to the size of a fishnet mesh. The mesh vibrator 6 is formed by attaching the ultrasonic vibrator 5 to one side of the lattice 4.
[0011]
As shown in FIG. 2, when the reticulated vibrator 6 configured in this way is connected to a part of a stationary net 7 and an oscillating current is passed from the oscillator (not shown) to the ultrasonic vibrator 5 of the reticulated vibrator 6, Ultrasonic waves are generated from the ultrasonic transducer 5.
[0012]
By generating ultrasonic waves in this way, seaweeds, oysters and the like do not adhere to the mesh vibrator 6, so that seawater passes through the mesh vibrator 6 and oxygen deficiency in the stationary net 7 can be prevented.
[0013]
【The invention's effect】
As is clear from the above description, in the ultrasonic fishnet of the present invention, an ultrasonic vibrator is bonded to a lattice substrate made of resin to form a mesh vibrator, and this mesh vibrator is made part of the stationary net. Incorporating and passing an oscillating current through the ultrasonic vibrator generates ultrasonic waves from the reticulated vibrator, which prevents seaweed and oysters from adhering to the reticulated vibrator. There is an advantage that the passage is not hindered and the lack of oxygen in the fish can be prevented.
