A safety protection device for a stern trawler net hauler is disclosed. An eccentric gear mechanism is mainly adopted, and the safety protection device of the net hauler drives an emergency stop switch to be switched off by breaking the gravity balance. The safety protection device consists of a positioning support seat, a torsion spring pre-tightening shaft, a torsion spring, a drive gear, a drive gear effecting shaft, a tension spring positioning shaft, a tension spring positioning shaft end nut, a carrier gear positioning shaft, a carrier gear positioning shaft positioning piece, a bearing,a carrier gear, a positioning bracket column, a first eccentric wheel effecting bushing, an eccentric wheel positioning piece, an eccentric wheel effecting shaft, a second eccentric wheel effecting bushing, an eccentric wheel effecting gear, an eccentric wheel and the like. The safety protection device has the main characteristics that by utilizing the physical characteristics of the eccentric wheel to break the principle of static balance, a pure mechanical structure special device, in which a power source of the net hauler is switched off by a self-saving touch mechanism, a dangerous situation transmitting mechanism and a net hauler emergency stop switching-off mechanism, is employed. The device has the advantages of simple structure, convenient installation and maintenance, high stability, adaptability to the harsh environment of stern trawler operation, reasonable structure, flexible motions, safety and reliability.
