Electromagnetic acceleration-based multipurpose lockable harpoon

Abstract

The invention discloses an electromagnetic acceleration-based multipurpose lockable harpoon. The harpoon comprises a harpoon base, wherein a harpoon rod base is fixedly connected to the upper part ofthe harpoon base; a harpoon rod is fixedly connected to the upper part of the harpoon rod base; the top of the harpoon rod is fixedly connected with a top connecting base; and an electromagnetic acceleration coil is arranged in the harpoon rod; the upper end and the lower end of the electromagnetic acceleration coil are fixedly connected with the top of the harpoon rod base and the bottom of the top connecting base separately; and an electromagnetic shielding layer is arranged between the electromagnetic acceleration coil and an inner wall of the harpoon rod. The invention relates to the technical field of fishing tools. The whole electromagnetic acceleration-based multipurpose lockable harpoon has a plurality of different use states; the harpoon can be used in a combined mode, can also beused independently and can also be used for catching large fish, so that the application range is wide, and the operation is easy and convenient. The harpoon head accelerated by a high-speed magneticfield can directly and easily pierce into a fish body in cooperation with a pyramid-shaped harpoon piercer, so that catching is convenient, and the hit rate of the harpoon ejected at a high speed canbe greatly increased.

Description

technical field [0001] The invention relates to the technical field of fishing tools, in particular to a multi-purpose lockable harpoon based on electromagnetic acceleration. Background technique [0002] Harpoon is a kind of fishing tool commonly used, and harpoon also needs to prevent fish from escaping after fishing except that sharp fork teeth can catch fish. High precision is required when forking a fish, and the fish must be caught only by piercing the fork spine into the fish's body. [0003] For example, a lockable harpoon is disclosed in the patent No. CN201621079110.2, which reduces the precision requirements of the traditional harpoon and improves the efficiency of the harpoon; The thorns on the fish are full of holes, the fish caught live for a long time, the aesthetics are preserved, and they have better market competitiveness. [0004] But existing harpoon can only be used for catching small fish, can't do anything to big fish, even can't insert fish body, an...
