Integrated device and method for generating power by utilizing tail plate opening and closing and impeller rotation vibration suppression

Abstract

The invention relates to an integrated device and method for generating power by utilizing tail plate opening and closing and impeller rotation vibration suppression. The device is composed of a sleeve main body module, a side wing rotating module and a tail swinging module. The sleeve main body module comprises a rotating bearing, a sleeve and a sleeve tail connecting shaft; the side wing rotating module comprises a power generation impeller, an arc-shaped magnet, a power generation coil and an impeller fixing shaft; and the tail swinging module comprises a front embedded magnet opening tail plate, a rear embedded magnet opening tail plate, a wire winding plate, a meshing gear, a rotating plate shaft and a tail plate connecting piece. Under the combined action that the side wing power generation impeller rotates to disturb a streaming boundary layer, a sleeve discharge outlet sprays outflow, and the tail swinging module is opened and closed in a reciprocating mode to swing to damage a tail vortex street, vortex-induced vibration suppression without energy consumption is achieved; and meanwhile, an induction wire cuts a magnetic induction line to generate current and supplies the current to a vibration monitoring device, and conversion and utilization of ocean current energy are achieved while vortex-induced vibration is suppressed.

Description

technical field [0001] The invention belongs to the technical field of marine new energy development and utilization and vortex-induced vibration suppression, and specifically relates to an integrated device and method for generating electricity by using tailgate opening and closing and impeller rotation vibration suppression. Background technique [0002] With the increasing difficulty of exploration and development of onshore oil and gas resources, offshore oil and gas resources have become the main alternative energy source and have received more and more attention. According to statistics, after 2006, marine oil and gas accounted for more than half of the newly discovered global oil and gas reserves. It is imminent to vigorously develop marine energy, which can effectively guarantee the country's energy security. In the process of offshore oil and gas exploitation, the riser is the link connecting the subsea wellhead and the offshore operation platform. When the sea ...

Problems solved by technology

At present, the main way to monitor the vibration characteristics of the riser is to install a vibration monitoring device on the surface of the riser to monitor the dynamic load response caused by the vortex-induced vibration in real time. The required electric energy is transmitted through the submarine cable, which consumes a lot of energy. lead to monitoring failure
