The invention relates to a clutch protective device for a net hauler of a fishing boat. The device consists of a friction clutch, an electromagnet, a movable ring mechanism, a fixed ring mechanism, a clutch shaft, a positioning rod, a spring, a fixed block and a connecting rod mechanism, wherein one side of the friction clutch is provided with the clutch shaft. The device is characterized in that: the movable ring mechanism and the fixed ring mechanism are arranged on the clutch shaft; the electromagnet is arranged above a pole of the fixed ring mechanism; the positioning rod and the fixed block are fixed on the friction clutch by welding; an emergency tread button is arranged beside a winding drum of the net hauler and is connected with the electromagnet; and if a person is wound in the net hauler, feet can be separated from the ground, the button acts to drive the electromagnet to attract and an iron core to indent, the fixed ring mechanism immediately quickly rotates downwards under the action of the spring to drive a clutch spindle to rotate, the clutch is released, and the winding drum of the net hauler stops rotating, so that crews can escape danger. The clutch protective device is very convenient to use.
Description
technical field [0001] The invention relates to a clutch protection device for a net hauler for a fishing boat, which mainly controls the clutch of the net hauler through an external electromagnet and an automatic reset mechanism, and belongs to the field of ship machinery. Background technique [0002] At present, a large number of fishing boats are manufactured relatively early, and people's hands and feet are often involved in the process of lifting the net, which has caused great harm to the personal safety of the fishermen. However, large-scale modernization of fishing boats will cost more Huge expenses, different hulls and complicated procedures, and it is difficult for the majority of fishermen to accept. Through research and investigation, it is found that most of the old-fashioned boats have friction clutches on the net haulers, and then through a cumbersome linkage mechanism, they are installed near the reel. A bulky wrench switch is used to drive the linkage mecha...
