Electricity-net composite fish blocking system and method

Abstract

The invention discloses an electricity-net composite fish blocking system and an electricity-net composite fish blocking method, wherein a rectangle ship passing net opening is formed in a ship passing passage which is arranged on a blocking net, and the size of the ship passing net opening fits in with the size of an electric fish-blocking and ship-passing facility, and a penetrating string is assembled in ship passing passage which is arranged on a blocking net; steel bars are arranged on the outer edge of a rectangle-shaped or U-shaped ship passing steel door frame of the electric fish-blocking and ship-passing facility and are used for connecting with a net-blocking and ship-passing net opening; the electric fish-blocking and ship-passing facility is arranged on the net-blocking and ship-passing net opening, two ends of the blocking net are fixed with ground anchors, a horizontal position of the electric fish-blocking and ship-passing facility and a vertical position of the electric fish-blocking and ship-passing facility are respectively fixed from four directions. The invention aims at providing the electricity-net composite fish blocking system and the electricity-net composite fish blocking method and the electricity-net composite fish blocking system and the electricity-net composite fish blocking method can not only effectively block fish, but also guarantee that large-tonnage ships can freely navigate without barriers for net blocking for fishing in large-scale landlocked waters.

Description

technical field

[0001] The invention relates to a fish-blocking device and method, in particular to a fish-blocking device and a method combining a traditional net fence and an electric fish-blocking free boat passing technology. Background technique

[0002] The traditional fish blocking equipment is to prevent the cultured fish from escaping from the breeding area by setting the blocking net on the selected fish blocking section. Down, or set the boat foil door, the boat net door, the boat boat facilities and other methods made up of floating boats, trapezoidal mesh and roof structure, as disclosed in Chinese patent CN86208852. These facilities or methods all need to pass through tangible substances, such as mesh sheets, foil doors, net doors, etc. to close the ship passage, and open the passage by manual or other external force when passing the ship, which cannot realize barrier-free and free ship passage.
