Oscillating type wave power generation device with extrusion pump, and control method thereof

Abstract

The invention provides an oscillating type wave power generation device with an extrusion pump, and a control method thereof. The oscillating type wave power generation device with the extrusion pumpis characterized in that an oscillating arm at at least one end of the oscillating type wave power generation device is connected with an electric generator through the extrusion pump, an air storagetank and a pneumatic motor; the extrusion pump comprises an oscillating vane plate, air bags, fixed plates, a rotary shaft and a support; the rotary shaft is connected with the oscillating arm; the oscillating vane plate is fixed onto the rotary shaft by adopting the rotary shaft as a symmetrical axis and is perpendicular to the axis of the rotary shaft; two ends of the rotary shaft penetrate through rotary shaft holes, provided with bearings, in support seats on two sides, so that the rotary shaft is erected on the support seats; a cross section of the fixed plates is in an X shape, and the fixed plates are fixed onto the support seats by adopting the rotary shaft as a symmetrical axis; the oscillating vane plate is limited between crossing parts of the fixed plates through the fixed plates, so that four relatively independent oscillating spaces are formed; and the four air bags are respectively arranged in the oscillating spaces. The waste and the loss of energy are reduced, and a performance of an existing oscillating type wave power generation device is greatly improved.

Description

technical field [0001] The invention belongs to the field of new energy power generation equipment, in particular to a swing type wave power generation device with a squeeze pump and a control method thereof. Background technique [0002] Chinese patent CN201711251476 proposes a swinging wave power generation device, which solves the problems of low power generation efficiency and low energy collection efficiency in surge power generation. However, the energy conversion mechanism scheme provided by this scheme has certain defects: if a piston pump or a double-vane rotary pump is used, the principle of extruding liquid or gas is to use a piston plus a sealing ring or a double-blade plus a sealing ring to communicate with the cylinder body. A closed space is formed. During the reciprocating motion, the sealing ring will generate huge friction with the inner wall of the cylinder, resulting in energy loss and wear of the device. However, if the flywheel solution is adopted, a l...

However, the energy conversion mechanism scheme provided by this scheme has certain defects: if a piston pump or a double-vane rotary pump is used, the principle of extruding liquid or gas is to use a piston plus a sealing ring or a double-blade plus a sealing ring to communicate with the cylinder body. A closed space is formed. During the reciprocating motion, the sealing ring will generate a huge friction force with the inner wall of the cylinder, resulting in energy loss and wear of the device.

However, if the flywheel solution is used, a large torque is required to start the flywheel, which may cause the wave to stop surging just as the flywheel is about to rotate, resulting in low energy utilization efficiency.
