The invention discloses an automatic hooking device and an automatic submersible sewage pump hooking device with the automatic hooking device. The automatic hooking device comprises a lifting frame, aspring, a lifting hook and a shaft. The lifting hook is of an eccentric structure and comprises an upper end portion and a lower end portion. The upper end portion is of a rod-shaped structure. The lifting frame comprises a first side plate. The upper end portion of the lifting hook is pivoted to the first side plate through the shaft. One end of the spring is installed on the upper end portion of the lifting hook. The other end of the spring is installed on the first side plate. The lifting hook has the gravity center. The gravity of the lifting hook exerts a first torque in one direction onthe shaft. The component force, in the vertical direction, of elastic force of the spring exerts a second torque in the direction opposite to that of the first torque on the shaft. The automatic submersible sewage pump hooking device comprises the automatic hooking device and can achieve lifting of the submersible sewage pump, and meanwhile the problem that by the adoption of conventional operation, a lifting chain falls off is avoided.
