Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It is worth mentioning that these descriptions are only exemplary, and are not intended to limit the scope of application of the present invention.

[0035] The floating device 1 floats on the surface of the fluid by the buoyancy force received by the float 200, and since the fluid containing part 400 is located below the float 200, the fluid containing part 400 is filled with fluid at this moment. When there are undulating waves in the fluid, the buoyancy of the buoyant 200 drives the floating device 1 to rise together with the waves during the rising stage of the waves. In the wave descending stage, because the movement of the floating device lags behind the waves, the fluid in the fluid containing part 400 cannot flow...

Abstract

The invention discloses a floating device. The floating device is used for utilizing wave energy. The floating device mainly comprises a rod assembly 100, a floater 200, a frame assembly 300 and a fluid containing part 400; the fluid containing part 400 is located below the floater 200 and floats up and down together with the floater along with waves formed by a fluid; and at a wave ascending stage, the fluid can enter the fluid containing part, and at a wave descending stage, the fluid containing part can prevent the fluid from flowing out of the fluid containing part. Thus, according to thefloating device, at the wave descending stage, energy input can be provided for an external device through the gravity of the fluid contained in the fluid containing part, the wave energy utilizing rate can be increased, and thus the cost of the floating device is lowered.

Description

technical field [0001] The invention relates to a floating device utilizing wave energy. Background technique [0002] A wave energy generator is a device that converts the mechanical motion of waves into electrical energy. There are many types of wave energy generation devices, among which the floating direct drive wave energy generation device is a new type of power generation device that converts wave energy into electrical energy through a linear motor, and is mainly composed of an oscillating buoy and a linear generator. The floating direct drive wave energy device uses the ups and downs of the float to drive the linear motor mover to reciprocate up and down, and directly converts wave energy into electrical energy without complex intermediate conversion devices such as gearboxes and hydraulic systems. Therefore, it has high reliability and less maintenance. [0003] The existing single-machine large-capacity floating direct-drive wave energy generation device uses the...
