Description

一种近岸海面波浪能发电装置  Nearshore sea surface wave energy generating device
【技术领域】 [Technical Field]
本发明涉及一种发电装置。  The invention relates to a power generating device.
【背景技术】  【Background technique】
由于波浪发电具有无污染以及不必耗费燃料之优点，如何利用海 水波浪所携带的能量来发电成为世界各国海洋工程研究人员研究的 目的。 我国大陆海岸线长达 18000多千米， 再加上各大小岛屿， 海洋 能源十分丰富。 随着可染能源日趋紧张， 研究、创新海洋发电技术是 一件意义深远的工作。  Since wave power generation has the advantages of no pollution and no need to consume fuel, how to use the energy carried by sea water waves to generate electricity has become the research goal of marine engineering researchers all over the world. China's mainland coastline is more than 18,000 kilometers long, plus the islands of all sizes, the ocean energy is very rich. As the dyeable energy sources become increasingly tight, research and innovation in marine power generation technology is a far-reaching task.
在海洋中， 近岸波浪与大海中心波浪的各种特性是有区别的。 大海中心波浪的特性是分波动层、过度层、静水层， 其中波动层与静 水层都是横向相对静止的， 而且波动层则会不停地上下纵向运动，另 外过度层的水流则比较复杂。近岸波浪则表现为一种涌浪， 涌浪与风 浪相比， 具有较规则的外形， 排列比较整齐， 波峰线较长， 波面较平 滑， 比较接近于正弦波的形状。而近岸波浪的另外一个最大特点就是 在涨潮与退潮时还跟随着水下有很强的水流。  In the ocean, the characteristics of the nearshore waves and the central waves of the sea are different. The characteristics of the center wave of the sea are divided into wave layer, excessive layer and still water layer. The wave layer and the still water layer are both relatively horizontal and relatively static, and the wave layer will continuously move up and down longitudinally, and the water flow in the excessive layer is more complicated. The near-shore wave is a kind of swell. Compared with the wind and waves, the swell has a more regular shape, a neat arrangement, a longer crest line, and a smoother wave surface, which is closer to the shape of a sine wave. Another great feature of near-shore waves is that they follow a strong underwater flow during high and low tides.
. 本申请人曾提交了一件专利申请， 申请号为 200810219431.1 , 名称为 "海洋波浪能发电的装置"， 申请日为 2008年 11月 21日。 虽然 上述的近岸海面波浪能发电装置实现了将波浪上下运动转换为转轴 转动带动发电机发电， 但这种方式只适用于大海中心的波浪，对于近 岸横向波浪则不适用了，所以需要继续探索研究近岸海面波浪能发电 装置。 The applicant has filed a patent application with the application number 200810219431.1, entitled "Equipment for Ocean Wave Energy Generation", and the application date is November 21, 2008. Although the above-mentioned nearshore sea wave power generation device realizes the conversion of the up and down motion of the wave into the rotation of the shaft to drive the generator to generate electricity, this method is only applicable to the wave at the center of the sea, for the near The lateral wave of the shore is not applicable, so it is necessary to continue to explore the wave power generation device near the shore.

下面结合附图对本发明进行详细说明：  The present invention will be described in detail below with reference to the accompanying drawings:
一种近岸海面波浪能发电装置， 包括能够随波浪上下往复的浮 体 1， 所述的浮体 1上支撑有发电机 2， 所述的浮体 1下方设有支架 3, 所述的支架 3上设有用于收集横向波浪水流并压缩加速的横向水 流收集加速器 4， 在所述的横向水流收集加速器 4的出水口 403处设 有由加速水流冲击转动的叶轮 5， 所述的支架 3上还设有用于平衡波 浪冲击横向水流收集加速器 4的平衡翼板 6， 所述的叶轮 5与所述的 发电机 2的转轴之间由传动机构 7连接。  The utility model relates to a near-shore sea surface wave energy generating device, which comprises a floating body 1 capable of reciprocating up and down with a wave, wherein the floating body 1 supports a generator 2, and the floating body 1 is provided with a bracket 3, and the bracket 3 is provided thereon. There is a lateral water flow collecting accelerator 4 for collecting the lateral wave water flow and compressing and accelerating, and an impeller 5 which is driven by the acceleration water flow is provided at the water outlet 403 of the lateral water flow collecting accelerator 4, and the bracket 3 is further provided with The balance wing 6 of the accelerator 4 is balanced by a wave impact lateral flow, and the impeller 5 is connected to the rotating shaft of the generator 2 by a transmission mechanism 7.
所述的横向水流收集加速器 4 包括横向设置的多个截面渐变的 水道 401， 所述的水道 401进水口 402大出水口 403较小。 所述的水 道 401为螺旋状设置。  The lateral water flow collecting accelerator 4 includes a plurality of cross-sectionally-graded water passages 401 disposed laterally, and the water inlets 401 of the water channel 401 and the large water outlets 403 are small. The water channel 401 is arranged in a spiral shape.
所述的横向水流收集加速器 4的进水口 402—端铰接在所述的支 架 3下端。  The water inlet 402 of the lateral water flow collecting accelerator 4 is hinged at the lower end of the bracket 3.
所述的平衡翼板 6为固定连接在支架 3的靠近所述的横向水流收 集加速器 4的出水口 403—侧上的横板。 所述的平衡翼板 6中部设有利用波浪冲击防止左右摇摆的竖向 平衡板 601。 The balance wing 6 is a transverse plate fixedly attached to the side of the water outlet 403 of the bracket 3 adjacent to the lateral water flow collecting accelerator 4. The middle portion of the balance flap 6 is provided with a vertical balance plate 601 that prevents the left and right swing by wave impact.
所述的浮体 1为中空的封闭腔体。  The floating body 1 is a hollow closed cavity.
所述的浮体 1与水流垂直的两侧设有平衡水箱 8， 所述的平衡水 箱 8顶部开口、 底部设有漏水小孔 801。  The floating body 1 is provided with a balance water tank on both sides perpendicular to the water flow. The balance water tank 8 has a top opening and a water leakage small hole 801 at the bottom.
. 所述的传动机构 7为软传动轴。所述的平衡翼板 6为水平设置。 所述的竖向平衡板 601与所述的平衡翼板 6垂直设置。  The transmission mechanism 7 is a soft drive shaft. The balance flap 6 is horizontally disposed. The vertical balance plate 601 is disposed perpendicular to the balance wing 6.
浮体 1两侧的平衡水箱可远离浮体的中心，两个水箱都与浮体固 定连接， 在不工作的情况下， 两水箱不突出水面。  The balance water tanks on both sides of the floating body 1 can be away from the center of the floating body. Both water tanks are fixedly connected to the floating body. When not working, the two water tanks do not protrude from the water surface.
竖向平衡板 601也可不安装在平衡翼板 6上，也可装在浮体 1或 叶轮 5背水的一侧。  The vertical balance plate 601 may not be mounted on the balance wing 6, or may be mounted on the side of the floating body 1 or the back side of the impeller 5.
当整个发电装置投入近岸涌浪的海面时，首先我们将多个发电装 置进行阵列网状软连接， 也即每个装置上部相对固定在原地， 由于水 是流动的，所以竖向平衡板 601'开始起作用， 使横向水流收集加速器 4的进水口 402始终正对水流，整个横向水流收集加速器 4开始工作， 这时进水口 402产生阻力，使发电装置下部向后摆动也即支架 3向后 摆动， 这样使平衡翼板 6尾部开始起来， 当进水口 402的力与平衡翼 板 6的力相等时发电装置就不再摆动而正常工作了，另外正是由于横 向水流收集加速器 4与支架 3下端铰接，所以在支架 3发生前后摆动 时进水口 402 也能正对水流， 但这并未能完全使发电装置很好的工 作， 由于水流的原因发电装置下部有可能左右摆动， 当向其中一边摆 动时支架 3带动浮体 1也同时转动， 同时也会使其中一个平衡水箱 8 突出水面， 而另一个平衡水箱 8则下沉， 当平衡水箱 8突出水面后就 马上产生了一个和发电装置下部摆动相反的力，所以最终使发电装置 保持平衡。 以上是在没有波浪或涌浪的情况下所产生的工作情况。 When the entire power generation device is put into the sea surface near the shore, firstly, we will arrange a plurality of power generation devices in an array mesh soft connection, that is, the upper portion of each device is relatively fixed in place, and since the water is flowing, the vertical balance plate 601 'Beginning to make the water inlet 402 of the lateral water flow collecting accelerator 4 always face the water flow, and the entire lateral water flow collecting accelerator 4 starts to work. At this time, the water inlet 402 generates resistance, so that the lower part of the power generating device swings backward, that is, the bracket 3 is backward. Swinging, so that the tail of the balance wing 6 starts to rise, when the force of the water inlet 402 is equal to the force of the balance wing 6, the power generating device no longer oscillates and works normally, and the other is due to the lateral water flow collecting accelerator 4 and the bracket 3 The lower end is hinged, so the water inlet 402 can also face the water flow when the bracket 3 is swung back and forth, but this does not completely make the power generating device work well. Due to the water flow, the lower part of the power generating device may swing to the left and right. When the swinging, the bracket 3 drives the floating body 1 to rotate at the same time, and also makes one of the balancing water tanks 8 The water level is highlighted, and the other balance water tank 8 sinks. Immediately after the balance water tank 8 protrudes from the water surface, a force opposite to the lower swing of the power generating device is generated, so that the power generating device is finally balanced. The above is the work that occurs without waves or swells.
当涌浪向上时，会使浮体 1产生带动发电装置向上运动的力， 另 外又会继续受到水流的作用，这时由于横向水流收集加速器 4可以绕 两个支点转动，使得横向水流收集加速器 4进水口 402的方向始终朝 着水流方向， 这就使进水口 402的进水量始终保持最大值。 同样， 当 涌浪向下降时两个平衡水箱以及发电装置自身重量的原因产生向下 的压力， 同时进水口 402的方向也会自动调整， 使得横向水流收集加 速器 4进水口 402的方向始终朝着水流方向。  When the swell is upward, the floating body 1 will generate the force that drives the power generating device to move upward, and in addition, it will continue to be affected by the water flow. At this time, the lateral water flow collecting accelerator 4 can rotate around the two fulcrums, so that the lateral water flow collecting accelerator 4 enters. The direction of the nozzle 402 is always in the direction of the water flow, which keeps the water intake of the water inlet 402 always at a maximum. Similarly, the downward pressure is generated by the two balance water tanks and the weight of the power generating device when the swell is descending, and the direction of the water inlet 402 is also automatically adjusted, so that the direction of the water inlet 402 of the lateral water flow collecting accelerator 4 is always oriented. Flow direction.
