Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Example is used to illustrate the utility model, but is not limited to scope of the present utility model.
Fig. 1 shows one according to a kind of electromagnetic power generation apparatus for marine fluid electricity generation system of the present utility model
Preferred embodiment.As illustrated, the electromagnetic power generation apparatus includes cylindrical type halbach permanent magnet arrays 1 and is arranged on the cylinder
On the inwall of type halbach permanent magnet arrays 1 and relative spacing set two pieces of conductive plates (the first conductive plate 2 and the second conductive plate
3).It is preferred that the conductive plate is copper coin.The electromagnetic power generation apparatus is positioned over seabed when using, and causes seawater to pass through the cylindrical type
The internal diameter of halbach permanent magnet arrays, due to seawater cut magnetic induction line that cylindrical type halbach permanent magnet arrays produce thus produce electricity
Energy.
Because cylindrical type halbach permanent magnet arrays have good characteristic：Internal magnetic induction intensity is uniform and one direction (such as
Shown in Fig. 2), the amplitude size of magnetic induction intensity is only influenceed by array boss ratio, interior when obtaining suitable magnet thickness
Magnetic field magnetic induction intensity can exceed the residual induction size of permanent-magnet material in itself.Leakage field is small and does not need screening arrangement.Therefore originally
The electromagnetic power generation apparatus that utility model is provided is effectively improved seawater and cut by using cylindrical halbach permanent magnet arrays
Cut magnetic induction line and produce the size of electric energy, therefore improve generating efficiency, and by the way that ocean energy directly is converted into electric energy, without in
Between turn can process so that energy conversion efficiency is higher.

Cylindrical type halbach permanent magnet arrays 1 are turnably connected with the other end of support 4, so that the electromagnetic power generation apparatus can
Change the entrance orientationses of cylindrical type halbach permanent magnet arrays 1 according to ocean current direction so that the direction of seawater flowing and cylindrical type
The diameter parallel of halbach permanent magnet arrays 1, to improve the size of gained electric energy, so as to further improve generating efficiency.
Specifically, product of the electric energy equal to electromotive force E and electric current I, electromotive force E and electric current I are with magnetic induction density B into just
Than then electric energy size and magnetic induction density B square are directly proportional, so increase magnetic induction density B is to improve to collect electric energy most
Effective method.Therefore in order to collect electric energy as much as possible, the preferably internal diameter of cylindrical type halbach permanent magnet arrays is 5-
15cm, external diameter is 8-20cm, so that internal produce magnetic induction density B as big as possible.
It is because seawater cutting magnetic induction line moves the induced electromotive force E produced：

The component in line direction,For perpendicular to the component of the speed of magnetic induction density B direction cutting magnetic induction line.Electric current can pass through following formula meter
Calculate：
Wherein, ρ is the resistivity of seawater, and a is the vertical height of conductive plate, and b is the first conductive plate 2 and the second conductive plate 3
Length, i.e. ab*L be effective cutting magnetic induction line seawater bulk.Therefore for the halbach magnetic arrays of cylinder, electricity
Can calculation formula be：
P=EI=B2V2πr0 2h/ρ
Wherein, π r0 2H is the seawater bulk of effective cutting magnetic induction line, equivalent to the ab* in electromotive force and current formula above
