As preferably, floating drum is provided with the filling port, and the filling port is provided with stopper, and stopper links to each other with brace by chain.After brace separates, the automatic water-filling of floating drum.Floating drum is reserved the filling port, and during proper functioning, the bath hole is clogged by rubber stopper, and rubber stopper is connected with brace by chain, and behind the low-intensity continuous damage, the rubber stopper of plug in the filling port pulled out by chain, and automatic water-filling of floating drum and sinking can not floated in typhoon from far.But caisson behind the typhoon, and reinstall.
As preferably, floating drum is provided with positioning device.Be more conducive to the salvaging of floating drum by positioning device.
As preferably, the distance of Magnetohydrodynamic(MHD) generator and wave energy trap setting is a 0.5-5 rice.
As preferably, the sea level is exposed in 1/5 to 1/3 of floating drum upper end.This height, wave energy is captured better effects if.
As preferably, the wave energy trap setting comprises two braces, forms cavity between two braces and the floating drum.Change original wave energy trap setting into hollow structure by plank frame.This change adapts to short period wave force localization in the characteristic at water surface, reduces the associated mass in the wave energy trap setting movement process, avoids the silt of conventional art wave energy trap setting bottom to dash silt simultaneously, and saves construction material.
According to the technical solution of the utility model, Magnetohydrodynamic(MHD) generator utilizes conductive fluid cutting magnetic line in magnetic field to generate electricity, the conversion efficiency height, and compact structure, good reliability is particularly suitable for the little actual conditions of China's wave energy density.The design of brace and floating drum adapts to short period wave force localization in the characteristic at water surface, reduces the associated mass in the wave energy trap setting movement process, avoids the silt of conventional apparatus wave energy trap setting bottom to dash silt simultaneously, and saves construction material.Being connected and the design of filling port and rubber stopper of brace and floating drum, solved the disaster reply problem that the wave energy trap setting must be faced.
