Cage system with detachable bottom net

Abstract

The invention discloses a net-cage system with a detachable bottom net. The system comprises an anchoring foundation, a net-cage frame and a side net installed under the net-cage frame, the bottom netis arranged on the bottom of the side net, dipseys are hung at the lower end of the side net at intervals, the bottom net comprises a bottom net frame and bottom netting bound in the bottom net frame, and the bottom net frame is bound to the tail ends of vertical belly lines of the side net; multiple water wings distributed at intervals are bound to the outer wall of the side net from top to bottom, an inflation and exhausting pipe is arranged on each water wings, and during changing of the netting, inflation is conducted on the water wings based on the inflation and exhausting pipes, so thatthe netting floats upward. According to the net-cage system, the side net is controlled and fixed by the bottom net frame and a bottom net fixing frame, so that the volume loss rate of the netting islowered; the bottom net is detachable, so that all kinds of aquaculture operations are convenient; synthetic fiber netting is adopted as the side net, while metal netting is adopted as the bottom net, so that the advantages of all kinds of materials are fully developed; the multiple water wings are bound to the side net, and by means of buoyancy of the water wings after inflation, the netting canautomatically float upward, so that all kinds of operations are convenient.

Description

Technical field: [0001] The invention relates to a mariculture cage, and more specifically, to a cage system with a detachable bottom net. Background technique: [0002] The net clothing of the cage can be divided into a side net and a bottom net according to the position relationship, and the side net and the bottom net are connected to form a closed breeding space. Generally, the bottom net of a traditional cage is not removable. Regarding the technical development of sea cages, the following issues are worthy of attention: [0003] 1. Cleaning of side net and bottom net: [0004] The larvae and spores of a large number of marine organisms and microorganisms can move with the current and attach to the seawater anti-wind and wave cages, which reduces the exchange of water bodies inside and outside the cages and deteriorates the aquaculture environment, which leads to the frequent occurrence of fish diseases in the cages and also makes the cages. The resistance and drift of the ne...

Problems solved by technology

On the sea surface, especially when the wind is high and the waves are high, the old nets must be replaced, and the new nets must be installed. The nets of large cages weigh several tons, and the manual operation is labor-intensive. The labor of the breeding workers poor personal safety
