Up-conversion electromagnetic-friction series composite wave energy collection system

Abstract

The invention relates to an up-conversion electromagnetic-friction series composite wave energy collection system. The system comprises a plurality of wave energy collection units which are connectedthrough ropes and are arranged in an array to form a net-shaped structure, wherein the wave energy collecting unit comprises a gravity rolling wheel, a driving seesaw, an inner gear, an outer gear anda movable wheel, the gravity rolling wheels are arranged on the driving seesaw and roll left and right along the driving seesaw, the inner gear is fixedly connected below the driving seesaw, the inner gear is meshed with the outer gear, the outer gear is meshed with a gear on the movable wheels, a plurality of permanent magnets are arrayed on the movable wheels along the circumference, a supportis arranged between the two symmetrical movable wheels and fixed on a sealing cover, a plurality of induction coils are arrayed inside the support along the circumference, and an electricity obtainingelectronic plate and an electricity losing electronic plate are respectively arranged on a lower side of the driving seesaw and an upper side of the support. The system is advantaged in that the output power under low-frequency weak excitation can be improved, and the system can effectively work under low-frequency wave excitation in any direction and is suitable for an all-weather marine environment.

Description

[technical field] [0001] The invention relates to the technical field of energy collection, in particular to an up-frequency electromagnetic-friction series composite wave energy collection system. [Background technique] [0002] Wireless sensor network is the main component of the Internet of Things, which can collect, process and transmit information generated in various activities, and has good application prospects in military investigation, environmental monitoring, biomedical and other fields. However, there are many internal nodes in the wireless sensor network, and the setting range is wide. If you want to ensure the long-term stable operation of the system, you cannot rely on the method of regularly replacing the battery to provide energy for the network operation. Therefore, collecting a large amount of dissipated mechanical energy in the environment, converting it into electrical energy through electromechanical energy conversion, and supplying power to tens of th...
