Problems solved by technology

When the flywheel is used to overcome the dead point, due to the large moment of inertia of the flywheel, a large starting torque is required when the mechanism is started, so the required starting flow rate is large, which limits the application area of ​​the power generation device, and the design of the flywheel needs to be accurately calculated. Flywheel needs special processing, poor replaceability
The link mechanism used to transmit the heave and pitch motion of the hydrofoil often has high requirements on the space position, so the size of the flywheel cannot be designed arbitrarily, which greatly increases the difficulty of design
However, when the dead point is overcome by dislocation arrangement, the mechanism cannot maintain complete symmetry, and in applications requiring symmetrical mechanisms, the dislocation arrangement method will be limited

Abstract

The invention discloses a dead-point-free oscillating hydrofoil type tidal current energy power generation structural body. An existing hydrofoil type tidal current energy power generation device does not have a solution to solve the dead point problem. The dead-point-free oscillating hydrofoil type tidal current energy power generation structural body comprises a vertical plate, a transmission rod, a rotating wheel, an elastic sliding block body and two hydrofoil pieces, wherein the vertical plate is vertically arranged, the transmission rod, the rotating wheel and the elastic sliding block body are all arranged on the same side face of the vertical plate, the elastic sliding block body is in sliding fit with the vertical plate, and the rotating wheel is arranged below the elastic sliding block body; and two hydrofoil pieces are hinged to one end of a long rod body, the long rod body is hinged to the vertical plate through a first shaft body, the other end of the long rod body is hinged to one end of a middle rod body through a second shaft body, a third shaft body sequentially penetrates through the other end of the middle rod body and one end of a short rod body and then is arranged on the outer side face of a rotating wheel, and the other end of the short rod body is hinged to the elastic sliding block body through a fourth shaft body. The dead-point-free oscillating hydrofoil type tidal current energy power generation is used for tidal current power generation.

Description

Technical field: [0001] The invention specifically relates to an oscillating hydrofoil type tidal current energy generating structure without dead points. Background technique: [0002] Tidal current energy generation devices mainly adopt three types: horizontal axis type, vertical axis type and oscillating hydrofoil type. Among them, horizontal-axis and vertical-axis turbines are currently the main methods used in large-scale tidal current energy generation equipment. However, due to the complex structure of the water turbine, high installation and maintenance costs, and high requirements for water depth, its installation and application are greatly restricted. The oscillating hydrofoil power generation device uses the hydrofoil with a certain angle of attack to form a pressure difference between the front and the back, resulting in heave and pitch motions, and drives the generator to convert mechanical energy into electrical energy. Oscillating hydrofoil power generation...
