Description
Technical field
The present invention relates to device for use in fishing trawl technical field, especially relate to a kind of for providing the longline fishing system with operator guards and the control method of protection to the fish risen to the bait in longline fishing.
Background technology
Longline fishing is a kind of fishing operation mode, distributes wide, quantity and output higher.Longline fishing generally includes the main rope of hundreds of nautical miles long, and main rope is provided with some branch lines, and branch line end has fishhook and bait, utilize the devices such as floating, sinker main rope is laid in waters table, in or bottom; The length of pull rope that control is connected with buoy and the outfit of settling capacity, be settled down to required water layer by fishhook.
Because the longline fishing activity duration is longer, some also will stay several tens minutes even 1,2 hour after a fish snapped at the bait in water, and the fish risen to the bait can be eaten up by other fishes, causes the cost increase of longline fishing, and economic benefit declines.
Chinese patent mandate publication number: CN201192038, authorize publication date on February 11st, 2009, disclose a kind of efficient tuna long liner fishing device, comprise a plurality of float, each float is connected with corkline, every root corkline connects main line simultaneously, and between every two floats, the two ends of main line hang with cement block weight, and the main line between two weights hangs with the complex root branch line of band fishhook; It is characterized in that, every root branch line is made up of interconnective parts, be followed successively by for be connected with main line automatically buckle, middle access be with plumbous change branch line first paragraph, nylon monofilament, stainless steel steel wire, sink lead and fishhook.The weak point of this invention is, function singleness, can not provide protection to the fish risen to the bait.
Summary of the invention
Goal of the invention of the present invention is the deficiency that can not provide protection in order to overcome longline fishing fishing gear of the prior art to the fish risen to the bait, and provides a kind of for providing the longline fishing system with operator guards and the control method of protection to the fish risen to the bait in longline fishing.
To achieve these goals, the present invention is by the following technical solutions:
Have a longline fishing system for operator guards, described longline fishing comprises main rope and is located at some branch lines on main rope, and every bar branch line is equipped with fishhook; Comprise the controller being located at the main rope upper end of surfacing, the memory be electrically connected with controller, display and alarm; Be positioned at and each branch line above fishhook be equipped with the housing of lower ending opening and be located at the cover plate of lower housing portion; Be trumpet-shaped protective cover when being provided with vertical extension spring in described housing and launching; Described protective cover top edge is connected with housing, and protective cover lower limb is provided with load-carrying block, is provided with the support ring that diameter from top to bottom increases gradually in protective cover top; Extension spring lower end be located at being connected for the baffle plate supporting cover plate in extension spring; Described cover plate is combined by some pieces of returning face plates and forms, and returning face plate outward flange is all hinged with housing lower end; When cover plate and housing close, protective cover and load-carrying block contact with returning face plate upper surface, and returning face plate lower surface contacts with baffle plate upper surface; Housing upper end is connected with branch line, and baffle plate is connected with fishhook by branch line;
At least one returning face plate is provided with angular transducer, and angular transducer is electrically connected with controller.
Protective cover of the present invention is used for around the fish risen to the bait, and avoids the fish risen to the bait to be eaten up by other predator, reduces economic loss.
Before fishhook is bitten by fish, under the pulling force effect of extension spring, cover plate and housing close, and protective cover is bound in housing, and protective cover can not cause interference to fishing;
When fishhook is bitten by fish, fish can pull fishhook and baffle plate to move down, and the pulling force that each returning face plate overcomes extension spring overturns downwards, and protective cover is stretched out under the effect of load-carrying block in housing; After controller judges to learn that returning face plate is opened by angular transducer; the fishing state value that fishhook corresponding with this angular transducer in memory is numbered by controller changes 1 into; protective cover expansion is cylindric and around fish body, under the protection of protective cover, other predator cannot have the fish risen to the bait.
When the fishhook of longline fishing more than 50% has fish, pack up the better economic benefit of longline fishing, otherwise will result in a loss; Angular transducer of the present invention can detect the rotational angle of returning face plate, according to the rotational angle detected, controller can judge whether fish rises to the bait, and calculate the catch rate of longline fishing, when catch rate exceeds rope closing threshold value V, controller can control alarm equipment alarm, staff can pack up longline fishing according to warning message, thus guarantees the economic benefit of longline fishing.
Therefore, the present invention has can automatically protect the fish risen to the bait after a fish snapped at the bait, effectively avoids the fish risen to the bait to be eaten up by other predator, good in economic efficiency feature.
