Description
Technical field
The invention belongs to the mechanical ﹠ electrical technology field, relate to a kind of electricity generating device that utilizes seawave power generation.
Background technique
Constantly the wave that rises and falls is containing huge energy, and this energy is never exhausted.So people have designed the various electricity generating devices that utilize seawave power generation.
For example, " Wave power generation device " that China Patent No. 200420097626.0 provides, it comprises a support that is connected with the seabed, the support upper support the hull that can swing, is hanging the generator that can swing in the hull.The rotating shaft of generator is provided with gear, and the inside bottom of hull is provided with the tooth bar that is certain radian, and wheel and rack is meshed.
When hull was swung along with wave, the relative position between the rack and pinion can change, because rack and pinion meshes together again, so just made gear rotate, and the rotating shaft of generator is along with rotation, thereby reached the purpose of generating.
As can be seen, hull just can reach the purpose of generating in the said apparatus at the effect lower swing of wave.But because generator is made up of each precision parts, generator is being hung its stability in use may be affected, and also can make the too early damage of generator when serious; Simultaneously, the long-time action mutually of wheel and rack can make its premature damage.Therefore, the working life of this device is shorter.
In addition,, adapt to above-mentioned situation, on hull, be provided with pulley, on pulley, be connected with sliding rope, just can adjust hull and be in position on the support by spurring sliding rope in order to make said apparatus owing to can be subjected to that flood tide or the influence of ebb tide.Because it is mixed and disorderly that sliding rope distributes, make this apparatus structure complexity, cost higher, and in case sliding rope disconnects, this device just can't proper functioning, its stability in use is relatively poor.
Summary of the invention
The objective of the invention is at existing in prior technology the problems referred to above, provide a kind of working stability height, working life long Wave power generation device.
Purpose of the present invention can realize by following technical proposal: a kind of Wave power generation device, comprise that an inside is the closed floating drum of cavity, be provided with support and generator in the floating drum with rotating shaft, the lead that joins with generator passes floating drum, be connected with the swinging block that to swing on the support, it is characterized in that, also be provided with oil hydraulic cylinder and oil hydraulic motor in the described floating drum by pipeline connection, be provided with linking mechanism between oil hydraulic cylinder and the swinging block, be provided with driving mechanism between the rotating shaft of oil hydraulic motor and generator.
This Wave power generation device is placed on the sea, and floating drum is connected by rope on the weight that places the seabed, for example anchor.Make it can not waft like this along with wave.
Wave promotes in the floating drum swing process, and the swinging block in the floating drum is along with swing.Make the hydraulic medium in the oil hydraulic cylinder flow by linking mechanism during the swinging block swing, hydraulic medium enters in the oil hydraulic motor by the road, makes oil hydraulic motor turn round; And then finally make the rotating shaft of generator rotate, thereby reach the purpose of generating by driving mechanism.
