Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the depth of the net cage in the water cannot be freely adjusted in the existing net cage for seawater culture, and to provide a liftable net cage suitable for seawater culture, which can be easily adjusted in the water. The depth of sinking and floating in seawater can meet the needs of different seasons, temperatures and different species of farming

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0036] Such as figure 1 As shown, a liftable net cage suitable for mariculture includes a rectangular parallelepiped frame 1 and a netting 11 arranged on the frame. The frame includes a plurality of vertical straight pipes 12, which are connected laterally to two adjacent straight pipes. The cross bar 13 between the pipes, in addition, we can also set an inclined diagonal tie bar 14 between two adjacent straight pipes to form a stable frame structure. In order to facilitate assembly, a detachable connection structure is preferentially adopted between the horizontal rod and the straight pipe and between the diagonal rod and the straight pipe to form a detachable connection, which facilitates disassembly and assembly, and can expand the size of the cage according to the needs of breeding. Specifically, such as figure 2 As shown, we can set a vertical connecting...

Abstract

The invention discloses a lifting net cage suitable for marine culture. The net cage comprises a plate body. The periphery borders are arranged at the edge of the inner side surface of the plate body. A guide hole is arranged in the center of the plate body. A button rod is arranged in the guide hole in a sliding mode. The end protruding out of the plate body, of the button rod is provided with a reset button. An annular press strip is arranged at the end surface of the periphery borders. An annular sealing groove is formed in the end surface of the annular press strip. Several positioning blind holes are formed in the length direction of the bottom surface in intervals, the positioning blind holes are in the forms of an inverse frustum, an elastic sealing gasket is arranged in the annular sealing groove. A gap exists between the sealing gasket and the side surface of the annular sealing groove. The positions corresponding to the blind holes, of the bottom surface of the sealing gasket are provided with positioning nails which are matched with the positioning blind holes. The positions corresponding to the positioning nails, of the front surface of the sealing gasket are provided with installation blind holes which extend into the positioning nails. The invention brings convenience to the installation of a control panel, guarantees the correct positioning of the sealing gaskets, at the same time, the reset button can flexibly function, and the service life of sealing parts can be prolonged.

Description

Technical field [0001] The invention relates to the technical field of sea cage culture, in particular to a sea culture net cage with adjustable suspension depth. Background technique [0002] With the development of marine aquaculture technology, a large number of aquaculture cages have appeared, which has changed the traditional simple fishing operation mode, produced high-quality aquatic products, and formed an efficient market competitiveness. The existing cages for aquaculture usually include nets, frames, anchor stones and floats, etc. The nets are woven with polyethylene threads or cotton yarns, and the frames are used to support the nets into a certain shape, usually about 10 cm in diameter. The floats are mostly made of foamed plastic floats or rigid plastic floats, which are evenly distributed on the frame or placed at the four corners of the frame to generate enough buoyancy to make the entire cage Floating on the water. Because cage culture often needs to adjust the...
