Abstract: An energy supply method and device for a monitoring wireless sensor node of a roller. A node energy supply device (2) is arranged on a roller web (1). The node energy supply device (2) comprises a generator (2-1), a disc rail (2-3), an input shaft (2-4), a swing link (2-5), a swing wheel (2-8) and an energy collection module (2-10). The generator (2-1) is driven to rotate using the rotation motion of the roller, the mechanical energy is converted into electric energy by the generator (2-1), and power is supplied to a monitoring wireless sensor node by the energy collection module (2-10). After rectification, filtering and voltage stabilization are conducted on the electric energy generated by cutting a magnetic induction line when the generator (2-1) operates, the energy collection module (2-10) uses the electric energy for charging an internal battery of the monitoring wireless sensor node. When the roller operates, the swing wheel (2-8) will keep vertically downward because of the gravity action thereof, thereby rotating relative to the input shaft (2-4) of the generator (2-1) to drive the generator (2-1) to operate. The present invention has the advantages of simple structure without manual operations, and energy saving and environmental protection.

Abstract: A cage energy supply system comprises wind power generation devices, a tail rope beam suspension device and a control device that are connected to the bottom of a cage box. The tail rope beam suspension device and the control device are located on the central axis of the bottom of the cage box, and the two sides of the tail rope beam suspension device are each connected to one wind power generation device. By means of the characteristics that the descending speed of the cage is high and the relative wind speed of an auxiliary shaft is high, the two wind power generation devices charge one storage battery at the same time, and the two storage batteries carry out charging and power supply alternately, so that a powered unit of the cage is supported by a stable and reliable power source all the time, the power supply requirement of the cage for the powered unit thereof is met, and meanwhile the power supply requirement for the control device is met. The devices are simple in structure and only need to be overhauled and maintained regularly. The present invention also relates to a control method for the cage energy supply system.
