Clutching mechanism of main line take-up device for abyssal fish long lines

Abstract

The invention relates to a clutching mechanism of a main line take-up device for abyssal fish long lines. The clutching mechanism is characterized by comprising an upper main shaft (10) and a lower main shaft (11) which are coaxial in the vertical direction, wherein two sets of steel sheets which are arrayed at an interval are arranged between the upper main shaft (10) and the lower main shaft (11); the first set of steel sheet (8) is fixedly connected with the upper main shaft (10); the second set of steel sheet (9) is fixedly connected with the lower main shaft (11); the clutching mechanism further comprises a handle (7) and a pressure spring; the pressure spring is used for tightly pressing the two sets of steel sheets arrayed at an interval by bolts; the handle (7) overcomes a pressing force of the spring to drive the upper and lower main shafts to be separated; the clutching mechanism is separated. According to the clutching mechanism, a great friction force is generated between the two sets of steel sheets due to the pressing effect of the pressure spring so as to drive the upper main shaft to rotate; when the take-up speed needs to be slowed, only the handle needs to be moved and the handle overcomes the pressing force of the spring so as to separate the two sets of steel sheets arranged at an interval; the speed of the upper main shaft is slowed rapidly and the upper main shaft rapidly stops rotating.

Description

technical field [0001] The invention relates to a main line take-up machine for deep-sea fish longline fishing, specifically, a clutch mechanism of a main line take-up machine for deep-sea fish longline fishing, and belongs to the technical field of fishery equipment. Background technique [0002] see figure 1 , the fishing method of longline fishing is to release a main line of tens of kilometers from the boat in the sea, and there are branch lines and floats tied at a certain distance on it, and the buoyancy of the floats is used to suspend the bait on the branch line in water of a certain depth , to lure fish to take the bait, so as to achieve the purpose of fishing. [0003] Longline fishing boats are generally equipped with a main line take-up device, which is used to take up the main line on the sea surface, and remove the hooked fish while taking the line. [0004] The take-up device generally adopts a motor to drive the traction roller, and the traction roller driv...

Problems solved by technology

[0005] The existing wire take-up device uses the motor and transmission mechanism to directly drive the traction roller to take up the wire. When the wire is taken up for a period of time, when it is necessary to suspend or intermittently take up the wire, some of them use the form of directly turning off the motor power supply, which is very inconvenient. It is convenient, and the motor is easily damaged when it is frequently started, which will shorten the life of the motor. Some learn from the principle of automobile clutches and use gear clutches to achieve separation and meshing between the motor and the transmission shaft, which solves the above problems. However, gear clutches are expensive. High cost and high requirements for manufacturing precision
