FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
A lantern fish trapping device as shown in fig. 1, which comprises a trapping net 1, an umbrella anchor 2, a connecting rope 4 and a fish gathering lamp 5.
The connection of the umbrella anchor 2 and the fishing vessel 3 can anchor the fishing vessel 3 by throwing the umbrella anchor 2, and the umbrella anchor 2 is the content of the prior art and will not be described in detail herein. The trapping net 1 is a conical net with an opening at the lower end, a connecting bracket is arranged at the top of the trapping net 1, and the trapping net 1 is hung at the bottom of the fishing boat 3 through the connecting bracket. The fishing boat 3 is provided with a catch pump pumping and transferring device, the connecting bracket is provided with a limiting hole, and a fish sucking pipe of the catch pump pumping and transferring device can be inserted into the trapping net 1 through the limiting hole.
One end of the connecting rope 4 extends into the trapping net 1 from the lower end opening and is connected with a connecting bracket at the top of the trapping net 1. The other end of the connecting rope 4 is connected with the umbrella anchor 2 and can be unfolded along with the putting of the umbrella anchor 2 to be far away from the fishing boat 3.
