Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-3 As shown, the present invention provides a sinking and floating flexible mesh structure fixed net fish-taking device, including an inflatable plane net body 2 arranged at the bottom of the fixed net 1, the inflatable plane net body 2 is provided with a vent 21, The air vent 21 communicates with the air compressor 4 through the connecting pipe 3, and a plurality of anchor bodies 5 are evenly spaced along the flow direction of the gas when inflated on both sides of the inflatable planar mesh body 2. The air outlet 21 connected by the connecting pipe 3 is used to inflate the inside of the inflatable planar mesh body 2 or draw air from the inside of the inflatable planar mesh body 2. With the help of the buoyancy of water, the inflatable planar mesh body 2 can be inflated along the fl...

Abstract

The invention relates to the technical field of fishing tools, and discloses a fixed net fish taking device with a floatable flexible net-shaped structure. The fixed net fish taking device comprises an inflatable planar net body which is arranged at the bottom of a fixed net, a ventilation port is formed in the inflatable planar net body, and communicated with an air compressor through a connecting pipe, the air compressor is used for inflating the interior of the inflatable planar net body or pumping air from the interior of the inflatable planar net body through the ventilation port communicated with the connecting pipe, multiple anchors are uniformly arranged at the two sides of the inflatable planar net body in the flowing direction of air during inflation at intervals, and with the assistance of buoyancy of water, the inflatable planar net body can gradually float in the flowing direction of the air during inflation; the floating part gradually squeezes the fixed net, and the capacity of the fixed net is gradually reduced accordingly; or the inflatable planar net body gradually sinks in the flowing direction of the air during air pumping, the sinking part is gradually separated from the fixed net, and the capacity of the fixed net is gradually increased accordingly.

Description

technical field [0001] The invention belongs to the technical field of fishing tools, and in particular relates to a sinking-floating flexible net structure fixed net fishing device and a method of use. Background technique [0002] Set net is a kind of trap fishing gear, which has attracted wide attention due to its low ecological impact and low fuel efficiency. According to the living habits of the fishing object and the hydrological conditions of the operating water area, the net gear, piles, anchors, etc. are laid in places near the sea or near the mouth of the fish where fish schools pass by. The fixed net is composed of a net wall to induce and block fish, a lifting net and a funnel net to guide fish into the net bag, and a rear net circle and a fish-taking part for collecting fish. The net wall extends from the coast to the waters nearly 100 meters deep. Usually, the scale of fishing gear is relatively large, and the fishing area where the final catch is collected is...
