Embodiment
Figure 1 shows that the plan view of the flow promoter regulator that the utility model the first embodiment provides.As shown in Figure 1, the utility model provides a kind of flow promoter regulator 10 to comprise framework 1 and at least one water guide board 4.Water guide board 4 is arranged at framework 1 to regulate the flow direction of current, and the straight line at water guide board place and water (flow) direction D1 form slanted angle θ and φ, and slanted angle θ and φ are greater than 0 degree.
In the first embodiment, flow promoter regulator also comprises 10 two rotating shafts 2 and at least four bounding meanss 3, and rotating shaft 2 and bounding means 3 are arranged at framework, and the quantity of water guide board 4 is at least two, one end connection rotating shaft 2 of each water guide board 4, the other end is against bounding means 3.Along with water guide board 4 is around rotating shaft 2 rotations, the other end of water guide board 4 is resisted against different bounding means 3.
In the first embodiment, framework 1 comprises the first support 11, the second support 12, the 3rd support 13 and the 4th support 14 being parallel to each other.The second support 12 and the 3rd support 13 are between the first support 11 and the 4th support 14.At least two rotating shafts 2 are arranged at respectively the second support 12 and the 3rd support 13, and at least four bounding meanss 3 are arranged at respectively the first support 11 and the 4th support 12.
Particularly, as shown in Figure 1, the quantity of rotating shaft 2 equals the quantity of water guide board 4, is eight.Four rotating shafts 2 are arranged at the second support 12, and other four rotating shafts 2 are arranged at the 3rd support 13.The quantity of bounding means 3 is 16.Wherein seven bounding meanss 3 are arranged at the first support 11 that is positioned at upstream, and other nine bounding meanss 3 are arranged at the 4th support 14 that is positioned at downstream.Yet the utility model is not limited in any way this.In other embodiment, flow promoter regulator 10 can only have the left one side of something shown in Fig. 1, or can, using left one side of something of the flow promoter regulator shown in Fig. 1 10 as a unit module, by repeated arrangement, form a more large-scale flow promoter regulator.
In the present embodiment, framework 1 is axially symmetric structure, and the position of a plurality of rotating shafts 2 is axisymmetric, and the position of a plurality of bounding meanss 3 is axisymmetric, and the position of a plurality of water guide boards 4 is axisymmetric.Particularly, respectively along central shaft X axisymmetricly, whole flow promoter regulator 10 arranges axisymmetricly with respect to central shaft Y for half, the left side and right half flow promoter regulator 10.
In the first embodiment, bounding means 3 is position-limited lever.Bounding means 3 comprises drift angle bounding means 31 and realizing middle limiting part 32.Drift angle bounding means 31 is arranged at respectively the drift angle of framework 1.In practical application, drift angle bounding means can be configured to by framework 1 propping up of itself.Realizing middle limiting part 32 is located at the centre of framework 1.The realizing middle limiting part 32 that the is positioned at upstream straight line at place that is connected with the realizing middle limiting part 32 that is positioned at downstream, D1 is not parallel with water (flow) direction, also forms non-vanishing angle.By this set, make the quantity of the realizing middle limiting part 32 of upstream and the realizing middle limiting part 32 in downstream unequal, and it is also asymmetric to arrange.
The length of water guide board 4 is longer than rotating shaft 2 to the distance between bounding means 3.Therefore,, when water guide board 4 is subject to water impact and rotates, its other end can effectively stop for limited 3, thereby make water guide board 4 cannot continue rotation to realize limit function.
Along with water guide board 4 is around rotating shaft 2 rotations, the other end of water guide board 4 is resisted against on different bounding means 3.Particularly, when current flow to this device along the D1 of water (flow) direction shown in Fig. 1, be positioned at the water guide board 4 of upstream against drift angle bounding means 31, be positioned at the water guide board 4 in downstream against realizing middle limiting part 32.When current flow to this device in opposite direction, water guide board 4 rotates around rotating shaft 2 under the impact of current, the water guide board 4 that was now originally positioned at downstream changes in upstream, and two water guide boards 4, jointly against another one realizing middle limiting part 32, are positioned at position shown in dotted lines in Figure 1.Originally the water guide board 4 that was positioned at upstream changes into and is positioned at downstream, and two water guide boards 4 are respectively against realizing middle limiting part 32.
The straight line at water guide board 4 places and water (flow) direction D1 form slanted angle θ and φ, and slanted angle θ and φ are greater than 0 degree.Particularly, when current flow to this device along direction shown in Fig. 1, be positioned at the straight line at water guide board 4 places of upstream and water (flow) direction D1 angulation and be not 0 slanted angle θ, be positioned at the straight line at water guide board 4 places in downstream and water (flow) direction D1 angulation and be not 0 slanted angle φ.When current flow in opposite direction, the slanted angle of formation is not also 0 degree.In other words, water guide board 4 of the present utility model can not be parallel to water (flow) direction all the time, but has certain slanted angle with water (flow) direction, thereby brings into play the effect of its guiding current.
Figure 2 shows that the plan view of the ocean power generating device that the utility model the first embodiment provides.Fig. 3 is the front view of Fig. 2.Figure 4 shows that the plan view under different water (flow) directions of the ocean power generating device that the utility model the first embodiment provides.Please also refer to Fig. 2 to Fig. 4.
As shown in Figure 2, ocean power generating device comprises flow promoter regulator 10, at least two water turbine 20 and generators 30.At least two water turbine 20 are arranged in framework 1.Generator 30 connects at least two water turbine 20.
In the first embodiment, the quantity of water turbine 20 is at least three and be even number, and adjacent two water turbine 20 arrange axisymmetricly so that the direction of rotation of adjacent two water turbine 20.
Particularly, the quantity of water turbine 20 of the present utility model is more than three or three.A water turbine of the general employing of existing electricity generating device.Yet only adopt a water turbine, in order to improve generated output, the diameter of water turbine can be very large conventionally, can greatly reduce the rotating speed of water turbine like this, increase moment of torsion simultaneously, cause the friction between central shaft and gear-box to strengthen, the cost of central shaft and gear-box is climbed to a higher point.In addition, the scale of whole electricity generating device also can be restricted.Yet, the utility model adopts at least three water turbine, is array-type and distributes, and so each water turbine is without too large, guaranteeing that generated output even improves under the prerequisite of generated output, effectively reducing the manufacture cost of water turbine and the working life of prolongation water turbine.In Fig. 2, drawn four water turbine 20, yet the utility model is not limited in any way to this.In other embodiment, vertical ocean power generating device can only have three water turbine 20.
In the present embodiment, a plurality of water turbine 20 are array setting side by side, and the bending direction of the blade 33 of adjacent two water turbine 20 axisymmetricly.As shown in Figure 2, every two water turbine 20 are one group and be arranged in parallel, and the sense of rotation of left side water turbine 20 is that the sense of rotation of right side water turbine 20 is clockwise counterclockwise.Sense of rotation by adjacent water turbine 20 is set on the contrary, effectively improves gathering and the evacuation of current, Lifting Water, thus the rotation of accelerating water turbine 20 is to improve the generating efficiency of generator 30.Yet the utility model is not limited in any way the quantity of water turbine 20 and sense of rotation.
In the present embodiment, the quantity of water guide board 4 is the twice of the quantity of water turbine 20, and every two water guide boards 4 are corresponding to a water turbine 20 and be arranged at respectively water turbine 20 along the upstream and downstream of water (flow) direction D1.
The left half of ocean power generating device of take below in Fig. 2 and Fig. 4 is example, describes water guide board 4 in detail and how to carry out water guide to improve the generating efficiency of generator 30.When current pour in along water (flow) direction D1, be positioned at the water guide board 4 of water turbine 20 upstreams under the percussion of current, the water guide board 4 in left side 2 turns clockwise around the shaft, the water guide board 4 on right side 2 is rotated counterclockwise around the shaft, no longer continues rotation until one end of water guide board 4 is stopped by drift angle bounding means 31.Now, water guide board 4 is positioned at the position shown in Fig. 2, forms angle theta and φ with water (flow) direction D1, and non-parallel.
Adjacent two water guide boards 4 that are arranged in upstream are jointly poly-by current, reduce like this current amplitude, improve flow rate, increase the impact force of current to water turbine 20, and the rotation that has strengthened water turbine 20 has increased substantially the generating efficiency of generator 30.Meanwhile, water guide board 4 is by the sense of rotation of water turbine 20 corresponding to current deflecting.Particularly, the water guide board 4 of upstream, left side is the sense of rotation close to water turbine 20 by current deflecting, counterclockwise, and the water guide board 4 of upstream, right side is the sense of rotation close to water turbine 20 by current deflecting, clockwise.Water guide board 4 by by current deflecting as far as possible perpendicular to the direction of the interior recess of the blade of water turbine 20, to strengthen the rotation of water turbine 20, thereby improve the generating efficiency of generator 30.
Current by water turbine 20 continue flow further downstream.Be positioned at the water guide board 4 in water turbine 20 downstreams under the percussion of current, the water guide board 4 in left side 2 is rotated counterclockwise around the shaft, and the water guide board 4 on right side 2 turns clockwise around the shaft, no longer continues rotation until one end of water guide board 4 is stopped by realizing middle limiting part 32.Now, water guide board 4 is positioned at the position shown in Fig. 2.Adjacent two water guide boards 4 that are positioned at downstream disperse current jointly, have strengthened draining dynamics, promote the inflow of upper waters.
Because the tidal energy in ocean energy is usually used in generating, therefore when flood tide and ebb tide, the water (flow) direction of seawater is completely contrary.When current commutation, when water (flow) direction D2 as shown in Figure 4 flows into, the water guide board 4 that was now once positioned at water turbine 20 downstreams becomes the upstream that is positioned at water turbine 20, and the water guide board 4 that is positioned at water turbine 20 upstreams becomes the downstream that is positioned at water turbine 20.
When current pour in (contrary with former water (flow) direction D1) along new water (flow) direction D2, be positioned at the water guide board 4 of water turbine 20 upstreams under the percussion of current, the water guide board 4 in left side 2 turns clockwise around the shaft, the water guide board 4 on right side 2 is rotated counterclockwise around the shaft, no longer continues rotation until one end of water guide board 4 is stopped by realizing middle limiting part 32.Now, water guide board 4 is positioned at the position shown in Fig. 4.
Seen from the above description, regardless of water (flow) direction, the sense of rotation of each water turbine 20 can not change, but the direction of rotation of adjacent water turbine 20.And regardless of water (flow) direction, thereby the rotational velocity that water guide board 4 can accelerate the sense of rotation of current deflecting water turbine 20 in water turbine 20 is to improve generated output.
In the present embodiment, the slanted angle θ that is positioned at upstream is greater than the slanted angle φ that is positioned at downstream.By this set, make upstream be inducted into as much as possible current by a larger margin, and downstream is as long as guarantee to discharge smoothly current.
