Netting fixing frame of square truss type net cage frame

Abstract

The invention discloses a netting fixing frame of a square truss type net cage frame. The netting fixing frame comprises a square truss type frame. Netting is arranged in the square truss type frame, a plurality of netting fixing frame unit components are arranged below the square truss type net cage frame, each netting fixing frame unit component comprises a vertical tube, fixing cables are penetratingly inserted in inner holes of the vertical tubes, two ends of each fixing cable are connected with each other to form a closed ring, and a tetrahedral truss is welded on the outer walls of the middle upper portions of the vertical tubes; the upper end surface of the tetrahedral truss is fixed to inner beam tubes and outer beam tubes of the square truss type net cage frame; the fixing cables are connected with spiral sleeves at the front ends of connecting ropes on the netting. The netting fixing frame has the advantages that the netting fixing frame is easy to assemble and can be easily and conveniently connected with the netting and separated from the netting, the netting can be fixed and restrained by the aid of the netting fixing frame, the large volume of the netting can be kept, and accordingly aquaculture spaces can be effectively maintained.

Description

Technical field: [0001] The invention relates to a seawater culture net cage, and more particularly relates to a net fixing frame for a square truss type net cage frame. Background technique: [0002] The frame materials for building large-scale seawater anti-wave net cages include HDPE pipes, metal pipes, floating ropes, rubber pipes and glass steel pipes, among which metal frames are generally used in square seawater anti-wave anti-wave net cages. Each prefabricated metal frame fitting of the square seawater anti-wave net cage is composed of upper beam tube, outer beam tube, inner beam tube, horizontal tube, oblique tube and vertical tube, etc., and the section is in the shape of oblique triangle. The square metal truss-type cage frame is composed of four long frames, and the superimposed parts of the four turning corners are fastened with pressure plates and U-shaped bolts of different specifications and shapes. After the metal frame is assembled, it is necessary to confi...
