CONSTITUTION:The objective reflecting mirrors for gathering fishes obtained by attaching each electric lamp 5 and reflecting mirrors 9 consisting of a concave mirror 11 and a concave case 10 for gathering the fishes set on a holding member 8 with screws 16 so as to preferably enter reflected light from the electric lamp 5 on the sea surface at about 45 deg. incident angle to a socket 6 and mounting a metal fixture 7 of the socket 6 on a mounting member 4 of a support 3 so as to direct the assembly to at least one outer sea surface of both sides of a fishing boat.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a reflector for a fish-collecting light used for squid fishing, etc.

[Conventional technology]

Traditionally, fish-collecting lights on squid fishing boats simply had a cap attached to the top of the light bulb to prevent the light from escaping upwards.

On the other hand, squid have a habit of trying to get inside the light of the fishing lights that are emitted around the boat, and this is used to catch squid. The stronger the light emitted around the boat, the more squid will attract it.

[Problem to be solved by the invention]

In the case of the above-mentioned conventional technology, the light of the electric light is not directly irradiated onto the sea surface, but is only diffusely reflected by the umbrella and directed toward the deck of the ship, and the reflectance is not very high. Therefore, the light from the electric lights was not effectively emitted around the ship. Moreover, these fish-collecting lights require an extremely large amount of electricity, and a large amount of energy is required to generate electricity.
It was desired to collect squid efficiently.

This invention was made in view of the above-mentioned conventional technology, and an object of the present invention is to provide a fish-collecting reflector that can effectively direct the light of an electric light toward the sea surface and has a large fish-collecting effect.

[Means to solve the problem]

This invention has an electrolyte for collecting fish that is attached to a post erected on the deck of a fishing boat. This is a fish collecting reflector equipped with a concave mirror that is attached to one side facing the sea surface.

[Effect]

The fish-collecting reflector of the present invention uses a concave mirror to effectively irradiate electrolyzed light for fish-collecting around a fishing boat, so that squid and the like can easily gather there.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

The fish-collecting lights 1 of this embodiment are mounted on the upper ends of a plurality of columns 3 erected in a line from the bow to the stern on the deck of a squid fishing boat 2, one on each side on the left and right for each column using mounting members 4. It is being The mounting member 4 is fixed perpendicularly to the column 3, and the fish-collecting lights 1 are fixed to both ends of the mounting member 4, respectively. Normally, 1 of these fish-collecting lights are installed on 1 boat.
Approximately 0 pieces are installed.

As shown in FIG.
A mounting bracket 7 is fixed to the socket 6, and the fish-collecting light 1 is mounted on the mounting member 4 of the support post 3 by the mounting bracket 7. Furthermore, a fish collecting reflector 9 is attached to the socket 6 by a holding member 8. In this fish collecting reflector 9, a glass concave mirror 11 having a spherical surface with a predetermined curvature is fixed to the inner surface of a pair of metal concave cases 10. Furthermore, the mounting angle of this fish-collecting reflector 9 is set so that the light reflected from the electrolyte 5 enters the sea surface at an incident angle of approximately 45° through the rod 15 that connects the holding member 8 and the concave case 10. The holding member 8 and the fish-collecting reflector 9 are detachably provided by screws 1B.

Furthermore, as shown in FIGS. 1 and 2, the starboard side 2a of the fishing boat 2
The fish-collecting light 1 on the side reflects the light of the electrolyte 5 toward the sea surface on the port side 2b of the fishing boat 2 with the outer one of its fish-collecting reflectors 9 reflecting the light of the electrolyte 5 toward the sea surface on the port side 2b of the fishing boat 2, and the inner fish-collecting reflector 9 9 is set so as to be reflected toward the sea surface on the starboard side 2a. At this time, the mounting angle θ of the outer fish-collecting reflector 9 is set to about 125°, and the mounting angle θ of the inner fish-collecting reflector 9 is set to about 135°.

This is because, as shown in Fig. 1, the outer fish collecting reflector 9 illuminates the sea surface on the opposite side of the port side 2b, so the mounting angle θ
This is because unless it is made smaller, light will not be effectively irradiated onto the sea surface. In addition, the fishing light 1 on the port side 2b side of the fishing boat 2 is
It is installed symmetrically with the fish light 1 on the starboard side 2a described above. The mounting angle of the fish-collecting reflector 9 can be finely adjusted using screws 12 and adjustment holes 13 in the concave case 10.

According to the fish-collecting light of this embodiment, the light emitted from the electrolyte 5 not only irradiates the sea surface directly, but also specularly reflects by the fish-collecting reflector 9 and irradiates the sea surface around the fishing boat 2. Moreover,
The concave mirror 11 has a spherical concave surface, and by changing the distance between the center of the electrolyte 5 and the concave mirror 11, the reflected light can be set to be diffused light, parallel light, or focused light. From above, it is better to have a slightly focused light, but this can be set as appropriate.

It has been experimentally confirmed that this increases the amount of squid that gather around the fishing boat by about 20% compared to the case where the fish collecting reflector 9 is not used.

Incidentally, the mounting position and angle of the fish collecting reflector of the present invention can be appropriately set as necessary, and the curvature of the concave surface can also be arbitrarily set to a desired value.

Further, the fish-collecting reflector may reflect the light of the fish-collecting light only to one side of the fishing boat depending on the usage situation. In this case, remove the fish-collecting reflector that illuminates the opposite side, or
Just change the angle.

Conversely, the fish collecting reflector may be attached to a desired side if necessary.

〔Effect of the invention〕

In the fish-collecting reflector of this invention, the light emitted from the electric light is specularly reflected by the concave mirror and irradiated onto the sea surface, so that a powerful beam of light is irradiated into the sea, making it easier for squid and the like to gather there.
