Abstract
The utility model discloses a back floating escape preventing fishing net, and aims at providing a back floating escape preventing fishing net which can effectively prevent the escape of the fish and which has strong capability of wave resistance, and which can make the floaters on the water freely pass. The utility model mainly comprises a bottom sinking block, a lower cable rope, a stand-up rope, a net slice, an upper cable rope, a strutting rod, a back floating net slice, a floating rope, a floater and a pulling rope. The utility model can be widely applied in the breeding of aquatic products in rivers, lakes and bays.
Description
Technical field
The utility model relates to a kind of anti-anti-fishnet of escaping that floats.
Background technology
At present, it mostly is that an aerial block that is higher than horizontal plane is set on block top that existing anti-fish flight anti-escapes fishnet, and its weak point is that the anti-height of escaping fishnet of this type is fixed, when running into big stormy waves or surge, fish is swum in groups against the current, forms regular flight; Simultaneously, this anti-to escape the net installation difficulty big, exposes to the weather, and is easy to be blown by stormy waves collapse, and wind loading rating is not strong, often causes great loss; In addition, the floating thing of the water surface can not be free often hang over and anti-ly escapes on the net by the anti-net of escaping, and has also destroyed the view of the water surface.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, a kind of anti-anti-fishnet of escaping that floats is provided, this is counter to float the anti-anti-drift-net sheet of escaping fishnet and encloses the waters direction towards the hurdle and swim on the water surface, and its height lifting along with the lifting of the water surface can effectively prevent the fish flight; Be difficult for being blown bad, have stronger capacity of anti-storm, and install simple by stormy waves; Simultaneously, the floating thing on the water surface can freely be prevented escaping net by counter floating, and has beautified water surface view.
The technical solution adopted in the utility model is: the utility model comprises lower cable, the net sheet, several end sinkers that are connected with described lower cable, be positioned at described lower cable top and be provided with upper cable, be fixedly connected on several floats on the described upper cable, spaced upright rope more than two or two, the two ends of described upright rope are connected on described upper cable and the described lower cable, four limits of described net sheet are connected with described lower cable and described upright rope with described upper cable respectively, one side that it also is included in described upper cable be provided with and above be fixed with the buoyant rope of several floats, between described upper cable and described buoyant rope, be provided with the pole more than two or two, between described upper cable and described buoyant rope, be provided with anti-drift-net sheet, four limits of described anti-drift-net sheet and described upper cable, described buoyant rope, described pole is connected.
Angle between described anti-drift-net sheet and the described net sheet is approximately an angle of 90 degrees, and described anti-drift-net sheet encloses the waters direction towards the hurdle.
One end of described pole is connected with the tie point of described upright rope and described upper cable, and described pole becomes about an angle of 90 degrees with described upper cable.
It also comprises stay cord, and an end of described stay cord is fixedlyed connected with described buoyant rope, and the other end of described stay cord is fixedlyed connected with described upright rope, and described stay cord is connected with described upright rope, described pole triangularity.
The beneficial effects of the utility model are; Because anti-drift-net sheet is to enclose the waters direction to float on the water surface towards the hurdle, become about an angle of 90 degrees to be connected with upright net, its height lifting along with the lifting of the water surface is so when running into big stormy waves or surge, can prevent effectively that fish from fleeing; In the use, run into when in water, moving about and be bordering on the floating net sector-meeting of the water surface and sink to continuing to move about forward according to fish, and when positive obstacles, will be provided with up and prevent escaping the net sheet from the motion habit of upper and lower or both sides migration, be provided with the net sheet forwardly and stop, so fish can't be advanced, have only downwards, about move about, get back to former blocking again and support the zone, institute is in case to escape performance splendid; Simultaneously, the floating thing of the water surface can freely pass through this net, has beautified water surface view; Because this anti-drift-net sheet is under water, is difficult for oxidation by air, thus durable in use, and easy for installation.
