Technical Field

The invention relates to a fishing tackle and a fishing tackle, in particular to a dip net.

Background

The existing dip net is a small-sized net fishing tool which is composed of a net bag, a frame and a handle and operates in a scooping mode, and the dip net is widely applied to fishing occasions, after fishes are shoveled into the shore by the dip net, the fishes in the net are transferred to a fish basket in water for temporary rearing, the dip net must be turned over, the fishes are poured into the fish basket from a frame port or are taken out from the dip net by a person and then moved into the fish basket, the operation is inconvenient, and the process can easily cause the fishes to escape if the fishes struggle or the operator loses hands, so that the potential safety hazard exists, and the defect of the existing dip net is overcome.

Disclosure of Invention

In order to overcome the two defects of inconvenient use and potential safety hazard, the invention provides the dip net adopting the net bottom opening and closing technology, the net bottom is put into the opening of the fish protector, the switch on the handle is pressed, the net bottom is automatically opened to generate an opening, fish is discharged from the opening and transferred into the fish protector, then the switch is released, the net bottom is recovered, the opening disappears, and the dip net is used for underwater operation again. The whole process is very convenient and safe.

The technical scheme adopted by the invention for solving the technical problems is as follows: an open-bottom type dip net comprises a main net, a movable bottom net, a frame and a handle, wherein a permanent magnet or an electromagnet is arranged at the bottom of the movable bottom net, a battery and a switch are arranged on the handle, an electric wire is attached to the outer side of a net bag, one end of the electric wire passes through the frame from the bottom of the net bag to the handle, and is connected with the electromagnet, and the other end of the electric wire is connected with the switch and the battery.

Foretell open end formula diddle-net, the string bag is connected by major network and a plurality of activity end net and is constituteed, and a plurality of activity end net forms the bottom of string bag through the concatenation of each other, and the end net forms half spherical net end shape after the concatenation together, and can part after the concatenation again. The splicing of the movable bottom net is characterized in that permanent magnets or electromagnets are arranged at the bottom of the movable bottom net and are distributed at the bottom of the net bag in a staggered mode, and under the condition that the electromagnets are powered off, the adjacent permanent magnets and the electromagnets are mutually attracted together, so that the bottom nets are also spliced together to form a net bottom, and the net bottom is in a closed state and is used for scooping operation in water; the bottom net is naturally dropped and separated from each other under the action of gravity to form a bottom opening, and the net bottom is put into the opening of the fish protector before, so that fish in the net can be discharged from the opening and enter the fish protector; after the fish is out of the net, the electromagnet is powered off, the polarity of the electromagnet disappears, the separated movable bottom nets are gathered together and spliced to form under the action of the magnetic force of the permanent magnet, and the net bottoms return to the closed state again to be ready to be put into water again for operation.

The fish protector has the advantages that the fish protector can be operated by one hand through the switch, the operation is very convenient, the net bottom is placed in the fish protector, the fish can fall into the fish protector after going out of the net from the opening, the whole process is very safe, and the fish cannot escape.

Detailed Description

As shown in fig. 2 and 4, the open-bottom dip net includes 4 movable bottom nets 1. The movable bottom net is a regular curved surface (as shown in figure 5) similar to a petal shape, as shown in figures 1 and 3, the arc-shaped fixed edges 4 are respectively connected with the main net bottom ring 6, and the arc-shaped fixed edges are connected end to end; the bottom 13 of each movable bottom net 1 is respectively provided with an annular permanent magnet 3 or an annular electromagnet 5, the two are distributed at the bottom of the net bag in a staggered manner, when the electromagnet 5 is powered off, the electromagnet is attracted by the adjacent permanent magnets 3 to form a closed annular shape, at the moment, the adjacent curve movable edges 2 between the movable bottom nets 1 are mutually overlapped, 4 movable bottom nets are combined into a semi-spherical shape to form a net bottom, the net bottom and the main net 7 form a complete net bag together, the net bag is connected with the frame 8, and the frame 8 is connected with the handle 10 to form a complete dip net.

As shown in figures 1 and 3, a battery 12 and a switch 11 are arranged on the handle 10, and the electric wire of the electromagnet 5 is attached to the outer side of the net bag from the bottom of the net and vertically passes through the frame 8 to reach the handle 10 to be connected with the switch 11 and the battery 12. The switch 11 is pressed, the electromagnet 5 obtains current, generates polarity, the polarity is opposite to that of the adjacent permanent magnet 3, repulsive force is generated on the permanent magnet 3, the attraction force of the permanent magnet 3 is offset, the permanent magnet and the electromagnet naturally fall under the action of gravity to drive each movable bottom net 1 to fall, the adjacent movable bottom nets 1 are separated from each other, an included angle is formed between the curved movable edges 2 which are overlapped together previously, the net bottom is opened, and the fishery catch objects in the nets are discharged from the openings; and then the switch 11 is released, the power supply 12 is disconnected, the polarity of the electromagnet 5 disappears, the permanent magnet 3 attracts the adjacent electromagnets 5 together again, so that the movable bottom nets 1 are in a splicing state again to form a closed net bottom, the opening disappears, and the movable bottom nets are ready to be used for underwater operation again.
