如图 1所示的,本发明的海浪发电装置安装在海上的浮台 10上。浮台 10 套在固定在海底的支架 20内。 浮台 10上固定有一个升降柱 90, 可随浮台的 升降而升降。 升降柱 90外设有套筒 80, 与升降柱 90呈螺紋配合, 因此, 在 升降柱 90升降的过程中, 通过螺纹带动套筒 80逆时针或顺时针旋转。 套筒 80上安装有转向相反的两组棘轮机构,即位于下面的第一组棘轮机构 70和位 于上面的第二组棘轮机构 60。 每组棘轮机构 60和 70由多个棘爪构成的内轮 和内周设有对应的多个棘齿的外轮构成, 具体结构将在后面介绍。 如图所示, 第一组棘轮机构 70的第一外轮 71通过履带 110带动第一发电机 40发电, 第 二组棘轮机构 60的第二外轮 61通过履带 110带动第二发电机 30发电。此外, 为了增加发电功率,在支架 20的四角上还安装有一台或多台风力发电装置 50 作为补充。 As shown in Fig. 1, the wave power generating apparatus of the present invention is mounted on a floating platform 10 at sea. The pontoon 10 is placed in a bracket 20 that is fixed to the sea floor. A lifting column 90 is fixed on the floating platform 10, and can be raised and lowered as the floating platform rises and falls. A sleeve 80 is disposed outside the lifting column 90, and is threadedly engaged with the lifting column 90. Therefore, during the lifting and lowering of the lifting column 90, the sleeve 80 is rotated by a thread to rotate counterclockwise or clockwise. The sleeve 80 is mounted with two sets of ratchet mechanisms that are opposite in rotation, namely a first set of ratchet mechanisms 70 located below and a second set of ratchet mechanisms 60 located above. Each of the sets of ratchet mechanisms 60 and 70 is constituted by an inner wheel composed of a plurality of pawls and an outer wheel having a corresponding plurality of ratchet teeth on the inner circumference, and a specific structure will be described later. As shown, the first outer wheel 71 of the first set of ratchet mechanisms 70 drives the first generator 40 to generate electricity via the track 110, and the second outer wheel 61 of the second set of ratchet mechanisms 60 drives the second generator 30 to generate electricity via the track 110. Further, in order to increase the power generation, one or more wind power generators 50 are additionally installed at the four corners of the bracket 20 as a supplement.
本发明海浪发电装置的传动部分的具体结构如图 2和图 3所示。 如图 3 所示, 升降柱 90的外圆周上沿逆时针方向间隔均匀的缠绕有工字型钢轨 91, 从而形成螺纹状。对应地,套筒 80的内圆周内设有容置钢轨的螺旋型凹槽 81。 通过这种结构可以实现升降柱 90与套筒 80间的螺紋配合。 在海浪作用下浮 台 10上升时, 升降柱 90上升, 通过螺紋旋转使得套筒 80逆时针旋转(从上 往下看); 相反, 在海浪作用下浮台下降时, 升降柱 90下降, 使得套筒 80顺
时针旋转。 显然, 套筒 80相对于升降柱 90升降而产生的旋转的方向可通过 改变升降柱 90上的螺紋旋转方向而改变。 The specific structure of the transmission portion of the wave power generating device of the present invention is shown in Figs. 2 and 3. As shown in Fig. 3, an I-shaped rail 91 is wound evenly around the outer circumference of the lifting column 90 in a counterclockwise direction to form a thread shape. Correspondingly, a spiral groove 81 for accommodating a rail is provided in the inner circumference of the sleeve 80. With this configuration, a threaded fit between the lifting column 90 and the sleeve 80 can be achieved. When the floating platform 10 rises under the action of the waves, the lifting column 90 rises, and the rotation of the thread causes the sleeve 80 to rotate counterclockwise (from the top to the bottom); on the contrary, when the floating platform descends under the action of the waves, the lifting column 90 descends, so that the sleeve 80 shun The hour hand rotates. It will be apparent that the direction of rotation of the sleeve 80 relative to the lifting column 90 can be varied by changing the direction of rotation of the threads on the lifting column 90.
如图 2所示, 套筒 80上安装有上下两组棘轮机构 60和 70。 结合图 5所 示, 第一组棘轮机构 70由第一内轮和第一外轮构成。 第一内轮包括多个由弹 簧和固定在弹簧上的锁胆构成的棘爪 73。 图 5中所示为 8个棘爪, 但本发明 并不限于此, 也可以采用如图 7所示的 4个棘爪。 所述多个棘爪构成的第一 内轮直接固定在套筒 80上随套筒 80的旋转而旋转。 如图所示, 第一外轮 71 的内圆周上设有与棘爪相配合的多个棘齿 72。当第一内轮随套筒 80逆时针转 动时, 棘爪 73抵在棘齿 72的端面上带动第一外轮 71—起转动, 这种状态称 为 "实档"; 当第一内轮随套筒 80顺时针转动时, 棘爪 73在弹簧弹力的作用 下收缩, 第一外轮 71不受任何影响, 在惯性的作用下而继续逆时针转动, 这 种状态称为 "空档"。 因此, 不论海浪是起是伏, 第一组棘轮机构 70 的第一 外轮 71始终沿逆时针方向旋转, 带动发电机发电。 此外, 第一外轮 71 的上 端面外沿还设有环行齿轨 75, 用于实现两组棘轮机构之间的相互牵引, 具体 将在后面介绍。 第一组棘轮机构 70的第一外轮 71可由设置在套筒 80上的带 井字架的滚动轴承支撑, 从而实现第一外轮可自由转动。 As shown in Fig. 2, the upper and lower sets of ratchet mechanisms 60 and 70 are mounted on the sleeve 80. Referring to Figure 5, the first set of ratchet mechanisms 70 are comprised of a first inner wheel and a first outer wheel. The first inner wheel includes a plurality of pawls 73 formed of a spring and a lock cylinder fixed to the spring. Although eight pawls are shown in Fig. 5, the present invention is not limited thereto, and four pawls as shown in Fig. 7 may be employed. The first inner wheel of the plurality of pawls is directly fixed to the sleeve 80 for rotation as the sleeve 80 rotates. As shown, the inner circumference of the first outer wheel 71 is provided with a plurality of ratchet teeth 72 that cooperate with the pawl. When the first inner wheel rotates counterclockwise with the sleeve 80, the pawl 73 abuts against the end face of the ratchet 72 to drive the first outer wheel 71 to rotate. This state is called "real gear"; when the first inner wheel follows When the sleeve 80 is rotated clockwise, the pawl 73 is contracted by the spring force, and the first outer wheel 71 is unaffected, and continues to rotate counterclockwise under the action of inertia. This state is called "neutral". Therefore, regardless of whether the waves are undulating, the first outer wheel 71 of the first set of ratchet mechanisms 70 is always rotated counterclockwise to drive the generator to generate electricity. Further, the outer edge of the upper end surface of the first outer ring 71 is further provided with a ring-shaped rack 75 for realizing mutual traction between the two sets of ratchet mechanisms, which will be described later. The first outer wheel 71 of the first set of ratchet mechanisms 70 can be supported by a rolling bearing with a derrick frame disposed on the sleeve 80 to effect free rotation of the first outer wheel.
第二组棘轮机构 60的结构如图 2和图 4所示, 由第二内轮和第二外轮构 成。 第二内轮的结构与第一内轮相似, 同样包括多个棘爪, 固定在套筒 80上 随套筒 80的旋转而旋转。 图 4中所示为 8个棘爪, 但本发明并不限于此, 也 可以采用如图 6所示的 4个棘爪。 第二外轮 61的结构与第一外轮 71相似, 其内圆周上也设有与棘爪 63相配合的多个棘齿 62。 当第二内轮随套筒 80顺 时针转动时, 棘爪 63抵在棘齿 62的端面上带动第二外轮 61—起转动, 这种 状态称为 "实档"; 当第二内轮随套筒 80逆时针转动时, 棘爪 63收缩, 第二 外轮 61不受任何影响,在惯性的作用下而继续顺时针转动,这种状态称为 "空 档"。 因此, 不论海浪是起还是伏, 第二组棘轮机构 60的第二外轮 61始终沿 顺时针方向旋转, 带动发电机发电。 The structure of the second set of ratchet mechanisms 60 is as shown in Figs. 2 and 4, and is composed of a second inner wheel and a second outer wheel. The second inner wheel is similar in construction to the first inner wheel and also includes a plurality of pawls that are fixed to the sleeve 80 for rotation as the sleeve 80 rotates. Although eight pawls are shown in Fig. 4, the present invention is not limited thereto, and four pawls as shown in Fig. 6 may be employed. The second outer wheel 61 has a structure similar to that of the first outer wheel 71, and a plurality of ratchet teeth 62 that cooperate with the pawl 63 are also provided on the inner circumference thereof. When the second inner wheel rotates clockwise with the sleeve 80, the pawl 63 abuts against the end face of the ratchet 62 to drive the second outer wheel 61 to rotate. This state is called "real gear"; when the second inner wheel follows When the sleeve 80 is rotated counterclockwise, the pawl 63 is contracted, and the second outer wheel 61 is unaffected, and continues to rotate clockwise under the action of inertia. This state is called "neutral". Therefore, regardless of whether the waves are up or down, the second outer wheel 61 of the second set of ratchet mechanisms 60 is always rotated in a clockwise direction to drive the generator to generate electricity.
此外, 如图 2所示, 第二外轮 61上还设有牵引齿轮 100, 最好是设置沿 圆周均匀分布的三个牵引齿轮 100 (图中其他两个牵引齿轮未示出), 分别与
第一外轮 71上对应设置的环形齿轨 75相啮合。 三个牵引齿轮 100垂直于第 二外轮 61的端面设置, 通过销轴固定在第二外轮 61上沿圆周间隔 120度开 设的通槽 64内, 并可绕销轴旋转。 牵引齿轮 100的下端穿过第二外轮 61后 与第一外轮 71上沿外圆周设置的环行齿轨 75相啮合。 通过这种方式既可以 将第二外轮 61支撑在第一外轮 71 的上方, 还可实现上下两个外轮之间的相 互牵引。 例如, 当第一外轮 71逆时针旋转时, 通过牵引齿轮 100与齿轨 75 的相互作用, 便可带动第二外轮 61顺时针旋转; 同样, 当第二外轮 61顺时 针旋转时, 通过牵引齿轮 100与齿轨 75的相互作用, 便可带动第一外轮 71 逆时针旋转。 这样的话, 在海浪起伏带动浮台 10和升降柱 90升降的整个过 程中, 第一外轮 71和第二外轮 61便可以保证一直不停的转动, 带动对应的 发电机 40和 30持续发电, 充分利用海浪起伏产生的能量。 In addition, as shown in FIG. 2, the second outer wheel 61 is further provided with a traction gear 100, preferably three traction gears 100 uniformly distributed along the circumference (the other two traction gears are not shown), respectively The corresponding annular racks 75 on the first outer wheel 71 are engaged. The three traction gears 100 are disposed perpendicular to the end surface of the second outer wheel 61, and are fixed by pins on the second outer wheel 61 in the through grooves 64 which are circumferentially spaced by 120 degrees and are rotatable about the pin shaft. The lower end of the traction gear 100 passes through the second outer wheel 61 and engages with the annular rack 75 disposed on the outer circumference of the first outer wheel 71. In this way, the second outer wheel 61 can be supported above the first outer wheel 71, and the mutual traction between the upper and lower outer wheels can also be achieved. For example, when the first outer wheel 71 rotates counterclockwise, the interaction of the traction gear 100 with the rack rail 75 can drive the second outer wheel 61 to rotate clockwise; likewise, when the second outer wheel 61 rotates clockwise, through the traction gear The interaction of 100 with the rack 75 can drive the first outer wheel 71 to rotate counterclockwise. In this way, during the whole process of the undulation of the floating platform 10 and the lifting column 90, the first outer wheel 71 and the second outer wheel 61 can ensure constant rotation, and the corresponding generators 40 and 30 can continue to generate electricity. Use the energy generated by the waves.
此外, 本发明可在第一外轮 71和第二外轮 61的外圆周上分别沿径向设 置两个或多个离心锤 120。 由于离心锤 120的牵引, 离心力增大, 两个外轮的 转动力和转速也就相应增加, 通过履带 110带动的两个发电机的功率也相应 增加。 为了防止棘轮机构旋转过程中, 第二外轮 61从上方飞出, 可在套筒 80 上第二组棘轮机构 60 的上方设置固定圈 (图中未示出) 以阻止第二外轮 61 在旋转过程中飞出, 该固定圈可采用现有的各种方式实现。 Further, the present invention can provide two or more centrifugal hammers 120 in the radial direction on the outer circumferences of the first outer wheel 71 and the second outer wheel 61, respectively. Due to the traction of the centrifugal hammer 120, the centrifugal force is increased, and the rotational power and rotational speed of the two outer wheels are correspondingly increased, and the power of the two generators driven by the crawler belt 110 is correspondingly increased. In order to prevent the second outer wheel 61 from flying upward during the rotation of the ratchet mechanism, a retaining ring (not shown) may be disposed above the second set of ratchet mechanisms 60 on the sleeve 80 to prevent the second outer wheel 61 from rotating during the rotation process. In the middle, the fixed ring can be realized in various existing ways.
以下将详细介绍本发明的浪发电装置的传动过程。 如 2图所示, 升降柱 90 随海浪上升使得套筒 80逆时针旋转 (从上往下看) 时, 第一组棘轮机构 70处于 "实档", 第一外轮 71在棘爪的带动下逆时针旋转, 带动第一发电机 40发电; 同时, 第二组棘轮机构 60处于 "空档", 第二内轮随套筒 80逆时针 旋转, 而第二外轮 61在牵引齿轮 100以及离心锤 120的作用下继续顺时针旋 转, 带动第二发电机 30发电。 升降柱 90随海浪下降使得套筒 80顺时针旋转 时, 第二组棘轮机构 60处于 "实档", 第二外轮 61在棘爪的带动下顺时针旋 转, 带动第二发电机 30发电; 同时, 第一组棘轮机构 70处于 "空档", 第一 内轮随套筒 80顺时针旋转, 而第一外轮 71在牵引齿轮 100以及离心棰 120 的作用下继续逆时针旋转, 带动第二发电机 30发电。 因此, 在海浪起伏的整 个过程中, 第一外轮 71始终逆时针旋转带动第一发电机 40持续发电, 第二
外轮 61始终顺时针旋转带动第二发电机 30持续发电。 The transmission process of the wave power generating device of the present invention will be described in detail below. As shown in Fig. 2, when the lifting column 90 is raised by the sea wave so that the sleeve 80 rotates counterclockwise (from the top down), the first set of ratchet mechanisms 70 are in the "real gear", and the first outer wheel 71 is driven by the pawl. Counterclockwise rotation causes the first generator 40 to generate electricity; meanwhile, the second set of ratchet mechanisms 60 are in "neutral", the second inner wheel rotates counterclockwise with the sleeve 80, and the second outer wheel 61 is in the traction gear 100 and the centrifugal hammer Under the action of 120, the clockwise rotation continues to drive the second generator 30 to generate electricity. When the lifting column 90 descends with the wave, the sleeve 80 rotates clockwise, the second set of the ratchet mechanism 60 is in the "real gear", and the second outer wheel 61 rotates clockwise under the driving of the pawl to drive the second generator 30 to generate electricity; The first set of ratchet mechanism 70 is in "neutral", the first inner wheel rotates clockwise with the sleeve 80, and the first outer wheel 71 continues to rotate counterclockwise under the action of the traction gear 100 and the centrifugal cymbal 120 to drive the second power generation. Machine 30 generates electricity. Therefore, during the entire process of the undulation of the waves, the first outer wheel 71 always rotates counterclockwise to drive the first generator 40 to continuously generate electricity, and second The outer wheel 61 always rotates clockwise to drive the second generator 30 to continue generating electricity.

According to the size of the offshore floating platform, multiple sets of the above-mentioned wave power generating devices can be installed on the floating platform, so that sufficient electric energy can be generated for various uses. For example, the electric energy generated by the wave power generating device is used in a thermal power plant, and the generated electric power is sufficient for a city.
