Description

一种兼作波浪能发电装置的固定式透空防波堤 技术领域
本发明涉及水工结构物动力实验装置技术领域，具体地讲是一种兼作波浪能发电装置的固定式透空防波堤。
背景技术
传统重力式防波堤存在着不能透过水流，不利于航运，导致泥沙淤积、水质污染等负面影响，与现代绿色港口工程建设相悖。透空式防波堤具有水体交换能力且施工方便，造价合理的新型防波堤更能适应当今深水港和“绿色港口”建设的发展要求。
透空式结构会增大波浪透过率，会使部分波浪透过堤体继续传播，影响掩护水域内的泊稳条件；且同一结构对不同波高和周期的波浪的透射、反射特性均不同，对港区内船舶的泊稳条件造成不利影响；海水和发电装置直接接触，容易造成海水侵蚀或者是浮游生物附着发电装置，致使发电效率低或者发电装置损坏等问题。
发明内容
本发明的目的是克服上述已有技术存在的不足，而提供一种兼作波浪能发电装置的固定式透空防波堤。
本发明提供的技术方案是：一种兼作波浪能发电装置的固定式透空防波堤，其特殊之处在于，由结构物、结构物固定装置和波浪发电机组三部分构成；
所述的结构物由水平承台板、第一上部弧形直立墙、第二上部弧形直立墙、第一下部挡浪板、第二下部挡浪板、围护垂直短管和围护通长管组成；
所述的水平承台板的两侧对应设第一上部弧形直立墙和第二上部弧形直立墙；
所述的第一上部弧形直立墙下方连接第一下部挡浪板上端，第一下部挡浪板与水平承台板垂直；所述的第二上部弧形直立墙的下方连接第二下部挡浪板上端，第二下部挡浪板与水平承台板垂直；
所述的水平承台板的两个开口侧均设围护通长管，围护通长管两端分别与第一上部弧形直立墙和第二上部弧形直立墙连接；所述的围护通长管上固定围护垂直短管；
所述的结构物固定装置由4根桩基柱子组成，4根桩基柱子分别与透空防波堤的水平承台板下面的四个角固定连接；
所述的波浪发电机组由安装在第一上部弧形直立墙、第二上部弧形直立墙内的螺旋轮叶组组成，通过软轴传动装置传动驱动发电机发电加以利用或储存。
进一步的，所述的第一上部弧形直立墙和第二上部弧形直立墙的两端与水平承台板之间均布置上部支撑柱子，连接组成斜三角形支撑。
进一步的，所述的第一下部挡浪板和第二下部挡浪板的两端与水平承台板之间均布置下部支撑柱子，连接组成斜三角形支撑。
本发明的突出的实质性特点和显著进步，1、根据港区环境，利用桩基将透空防波堤固定，保证结构物稳定；2、结构整体性好，造价低，利用率高，易于使用；3、结构各部分连接力学性能好，结构稳定；5、与传统透空堤相比，可根据不同试验环境开展不同比尺的结构物水动力的试验，在迎浪面背浪面设置挡板有效消减部分入射波；6、消浪效果良好，结构受力较小，水体交换能力和掩护效果均良好，结构型式简单，便于实际工程的应用；7、经过对该种防波堤发电装置的组成结构及布置方式的综合考量，其具有结构稳定、消能效果好、发电转化效率高、安装便捷、易于维护，建设工期短等特点。
