Friction energy harvesting self-powered monitoring system

Abstract

The invention relates to a self-powered monitoring system for friction energy harvesting, and belongs to the field of measurement and new energy, a base is arranged at the end part of the side wall of a machine shell, a fixed disc is pressed in the machine shell, and fixed electrode plates and fixed friction plates are arranged on the upper side and the lower side of a fixed disc body; long and short step rods are respectively arranged on the upper and lower sides of a ball head of the torsion rod; the ball head is arranged in a ball cavity in the top wall of the shell; a frequency modulation block and a bluff body with a ribbon on the side wall are arranged on the long step rod; the bottom wall of the bluff body abuts against a disc spring arranged above the top wall of the machine shell. The end part of the short step rod is provided with an excitation disc; a sleeve barrel consisting of a sleeve barrel wall and a barrel top wall is arranged on a guide column on the base, and sensors are uniformly distributed on the top wall of the sleeve barrel; the sensor is in contact with a top ring of the excitation disc; a group of movable discs are sleeved on the wall of the sleeve barrel and are fixed through a pressing ring; the pressing ring is arranged at the end part of the wall of the sleeve barrel and presses the disc-shaped spring on the base; a gap is reserved between the movable disc and the fixed disc; movable electrode plates and movable friction plates are adhered to the upper side and the lower side of the movable disc body; and the movable friction plates and the fixed friction plates are made of different materials.

Description

technical field [0001] The invention belongs to the technical field of monitoring and new energy, and in particular relates to a self-powered monitoring system for frictional energy harvesting. By collecting wind energy or vibration energy, a self-powered ship-borne wind direction monitoring, ship turbulence amplitude and direction monitoring, and a ship positioning and tracking system are constructed. Background technique [0002] In order to ensure the safety of the ship's navigation, the crew must pay attention to the natural environment of the relevant waters and its changes in real time, such as wind direction, wind speed, waves, etc. Therefore, people have gradually developed various types of ship-borne monitoring systems and gradually obtained practical applications. In addition, in order to achieve the purpose of ship navigation safety, timely rescue, and rapid search for accidents, the ship positioning and tracking system has also been widely used on civilian ships....

Problems solved by technology

However, the system functions of the existing related power generation devices are single, the natural frequency of the friction power generation unit is fixed, and the effective bandwidth is narrow. Once the product leaves the factory, it cannot be adjusted, so it cannot meet the application of ships with different purposes, different tonnages, different water areas and different functions. need
