Problems solved by technology

[0006] In order to adjust the irradiation angle of such a conventional fish-collecting light device, it is necessary to loosen the fixing fixture of the lamp to change the setting angle of the fish-collecting light device, or move the facility parts that fix the lamp to change the angle, and perform the fish-collecting light during operation. The angle adjustment of the device is very difficult

Embodiment Construction

[0063] Hereinafter, preferred embodiments of the fish light device for carrying out the present invention will be described in detail. First, the fish light device of this invention is demonstrated based on 1st Embodiment.

[0064] Fish-collecting light device 1 of the present invention is shown in Figure 1, and it has: Fish-collecting light 10, is carried on the hull S, irradiates light to sea surface; Angle variable device 20, changes the pitch angle of fish-collecting light 10; Detection mechanism 30. Detect the rotation angle of the hull S caused by pitching phenomenon, swaying phenomenon, etc.; the control mechanism 40 controls the variable angle device 20 according to the rotation angle of the hull S detected by the detection mechanism 30, and corrects the pitch angle of the fishing light 10 for the specified value.

[0065] A plurality of fishing lights 10 are horizontally arranged on the upper part of the hull S, and illuminate both sides of the hull from the bow towa...

Abstract

A fish lamp device capable of freely adjusting an illuminating angle, particularly, keeping an illuminating direction constant even if a ship is rolled. The fish lamp device comprises fish lamps mounted on the ship and illuminating a sea surface, an angle changeable device for changing the elevation angle of the fish lamps, a detection means for detecting the rotating angle of the ship resulting from pitching and rolling, and a control means controlling the elevation angle of the fish lamps to a prescribed value by controlling the angle changeable device based on the rotating angle of the ship detected by the detection means.

Description

technical field [0001] The present invention relates to a fish collecting light device used in fishery. Specifically, it belongs to the technical field of fishing-related fish-collecting light devices for gathering aquatic animals such as squid, saury, horse mackerel and mackerel. Background technique [0002] Conventionally, in fishery operations, fish-collecting lights have been used for the purpose of gathering as many target organisms as possible within the operating range of fishing gear from a sea area larger than that of one's own boat to facilitate fishing. The operation process of fishery consists of the process of detecting target organisms (fish detection), the process of trapping (fish collection), and the process of fishing (fishing). The light of the fish collection light is an important factor affecting the efficiency of fishing. The main target organisms of Jiyudeng fishery include phototaxis squid, saury, horse mackerel, mackerel, and the like. [0003] Th...
