The invention discloses an automatic cooling device for a disc brake of a petroleum drilling rig winch. The automatic cooling device is characterized in that a cooling water pump, a water pump motor and a functional water tank are installed on a pry base; a radiator fan and a fan motor are installed above the functional water tank; an auxiliary water tank is installed above the radiator fan, an external water filling nozzle is formed in the top end of the auxiliary water tank, and the bottom end of the auxiliary water tank is communicated with the functional water tank through an S-shaped radiating tube; a water inlet of the cooling water pump stretches into the functional water tank, a water outlet of the cooling water pump is communicated with a cooling passageway of a winch brake disc through a water outflow passageway, and the bottom of the cooling passageway of the winch brake disc is connected back to the auxiliary water tank through a water return pipeline; and all sensors are connected with a controller; and the output end of the controller is connected with the water pump motor, the fan motor and an alarming device. The automatic cooling device is compact in structure, high in integration level, stable in automatic control performance, high in intelligent degree and excellent in cooling effect and can be wholly moved along with the drilling rig winch.
