Embodiment

[0022] Such as figure 1 As shown, the transmission type vertical lifting fishing device of the present embodiment includes a three-phase motor 1, a fishing net 2 and two load-bearing ropes 3, and the fishing net 2 of the present embodiment is set to a square or a rectangle, preferably 50m× 50m, the central part of the fishing net 2 is provided with a concave fish pocket 16, and the four corners of the fishing net 2 are connected with a settling bag, and the fish pocket 16 at the center of the fishing net 2 is connected with a fish luring bag. Two load-bearing ropes 3 are parallel in the horizontal direction, and the three-phase motor 1 is provided with a reel with a gearbox, and in this embodiment, the rotation direction of the reel can be controlled by controlling the three-phase motor 1, thereby controlling the rising or falling of the fishing net 2 .

[0023] This embodiment also includes four uprights for fixing the ends of two load-bearing ropes 3. The four uprights incl...

Abstract

The invention discloses a transmission type vertically-lifting fish-trapping device which comprises a three-phase motor (1), a square or rectangular fishing net (2), two horizontally-parallel head ropes (3) and four uprights for fixing end heads of the two head ropes (3), wherein the three-phase motor (1) is provided with a reel with a gearbox, two first pulleys (9) are connected to the two head ropes (3), four second pulleys (10) are respectively arranged on the four uprights, four digging ropes (14) are respectively connected to four corners of the fishing net (2), the other ends of the digging ropes (14), which are relatively connected to the fishing net (2) sequentially bypass one first pulley (9) and one second pulley (10) and then are wound on the reel, and one digging rope (14) is correspondingly connected with one first pulley (9) and one second pulley (10). By adopting the structure, the transmission type vertically-lifting fish-trapping device has the advantages of simple structure, convenience for operation during the fish trapping, and capability of rapidly casting as well as collecting and lifting the fishing net.

Description

technical field [0001] The invention relates to the field of fishing, in particular to a transmission type vertical lifting fishing device. Background technique [0002] At present, when fisheries are carried out on rivers, rivers, and lakes, people mainly fish by manually casting nets. It is time-consuming and laborious to use this fishing method to cast nets and bring fish caught in the nets to fishing boats, and the efficiency is low. During the process, the net cannot be collected in time when sudden floods or ships pass by. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a transmission type vertical lifting fishing device capable of quickly casting and retracting the net. [0004] The purpose of the present invention is mainly achieved through the following technical solutions: a transmission type vertical lifting fishing device, including a three-phase motor, a square or rectang...
