Description

一种带双曲线齿条的波浪发电装置
技术领域
本发明涉及一种发电平台，主要是一种带双曲线齿条的波浪发电装置，属于海洋能设备领域。
背景技术
目前的波浪能发电平台基本上都是固定式，因此都配置有长长的油缸活塞杆，这样的结构造成油缸活塞杆刚性不足，不够稳定，而且使用寿命相当的短，无法适应大功率机组进行发电，是一个急需解决的问题。
发明内容
本发明的目的是提供一种带双曲线齿条的波浪发电装置。
本发明要解决的问题是现有长油缸活塞杆式发电平台使用寿命短，无法适应大功率发电的不足。
为实现本发明的目的，本发明采用的技术方案是：
一种带双曲线齿条的波浪发电装置，包括浮箱、滚轮机构、导向柱、发电平台、液压能量转换机构和十字升降杆，导向柱打入海底，导向柱上安装有发电平台，发电平台中间的孔中安装有十字升降杆，十字升降杆的下部通过活动连接杆与浮箱固定在一起，浮箱两侧安装有滚轮机构，滚轮机构紧贴在导向柱上；发电平台上安装有液压能量转换机构，液压能量转换机构与十字升降杆相互配合进行能量转换运动。
所述液压能量转换机构包括壳体、单项液压缸和滚动轮，单项液压缸头部安装有滚动轮，壳体内安装有八组单项液压缸，每边四组相互对称，中间的空隙用于通过十字升降杆。
所述十字升降杆包括两条曲线齿边和两条直线边，两者对称安装，两条曲线齿边为摆线结构；所述导向柱设有三个，以十字升降杆为中心，三个导向柱间距相同，与之对应的浮箱通过滚轮机构紧贴在导向柱上；所述上下两个滚动轮的间距为曲线齿边波峰到波谷距离的3/4。
本发明的优点是：本装置通过液压能量转换机构与十字升降杆的配合，解决了波浪发电过程中一个潮位差的控制与适应问题，有效解决了现有发电平台不能随潮位变化的难题，适宜大功率机在波浪发电中的运用，应具有广阔的市场空间。

具体实施方式
下面结合附图及实施例对本发明作进一步的说明。
如图所示，1、一种带双曲线齿条的波浪发电装置，包括浮箱1、滚轮机构2、导向柱3、发电平台4、液压能量转换机构5和十字升降杆6，其特征是：导向柱3打入海底，导向柱3上安装有发电平台4，发电平台4中间的孔中安装有十字升降杆6，十字升降杆6的下部通过活动连接杆与浮箱1固定在一起，浮箱1两侧安装有滚轮机构2，滚轮机构2紧贴在导向柱3上；发电平台4上安装有液压能量转换机构5，液压能量转换机构5与十字升降杆6相互配合进行能量转换运动。
液压能量转换机构5包括壳体51、单项液压缸52和滚动轮53，单项液压缸52头部安装有滚动轮53，壳体51内安装有八组单项液压缸52，每边四组相互对称，中间的空隙用于通过十字升降杆6。
十字升降杆6包括两条曲线齿边61和两条直线边62，两者对称安装，两条曲线齿边61为摆线结构，这样能减少曲线齿边61与滚动轮53配合运动时的摩擦力，而且能使滚动轮53实现平稳过渡曲线齿边61的波峰与波谷。
导向柱3设有三个，以十字升降杆6为中心，三个导向柱3间距相同，与之对应的浮箱1通过滚轮机构2紧贴在导向柱3上，这样呈一个三角形结构，使其增强抗风浪能力，也有利于提高使用寿命。
上下两个滚动轮53的间距为曲线齿边61波峰到波谷距离的3/4，这么相互间不会产生死角的问题，以提高能量转换效率。
本装置的使用方法：当整个装置安装好后，浮箱1随波浪的起伏在导向柱3的配合下带动十字升降杆6实现上下运动，在十字升降杆6上下运动的同时带动液压能量转换机构5中的单项液压缸52来回运动，将浮箱1的机械能转变为液压能储存起来进行发电，这样的设备能量转换密度大，适于海上大型液压发电装置的产业化。
