Description

一种可控式半开放的养殖舱系统 技术领域
本发明涉及深远海渔业技术领域，特别是涉及一种可控式半开放的养殖舱系统。
背景技术
随着社会经济的不断发展，沿海海洋环境污染加重，传统养殖方式效益下降、养殖品种病害严重。在资源环境刚性约束日趋加剧的背景之下，如何提高养殖密度与单位水体产量，减少养殖环境污染成了急需解决的问题。目前的发展方向是将拓展外海养殖空间，大力发展海洋牧场立体养殖、外海深水网箱养殖作为重点工作任务。统筹海洋渔业资源开发，支持集约化海水健康养殖，优化养殖空间布局，探索和开发绿色、健康的海水养殖模式成为海水养殖业持续高效发展的必由之路。
深远海养殖工船作为一种新型的海洋作业平台以及养殖模式，受到海洋工程以及海洋养殖产业领域的广泛关注，养殖工船通过自主航行寻找最优质水源和最佳养殖水温环境，既可规避台风和赤潮等自然灾害影响，也可有效规避近海养殖污染与远海养殖风险，实现全季节高效生产，保障优质水产品供给。目前其养殖模式主要有两类：一是采用封闭循环水养殖；二是采用全开放式养殖。前者需要加装专门的封闭式循环水水处理系统，中国海洋大学和中国水产科学院渔业机械仪器研究所设计的鲁岚渔养61699为代表，其系统构建成本高、运行成本大；后者则是养殖网箱完全放置于海域中，完全利用所处海域的海水流速进行水交换，不需要任何水处理，以挪威NSK船舶设计公司设计的大型深海养殖工船为代表，属于完全开放式养殖模式，但养殖环境也完全依赖于所处海域，基本属于传统的养殖模式。
发明内容
本发明的目的是提供一种可控式半开放的养殖舱系统，以解决上述现有技术存在的问题，能够有效降低因封闭循环水养殖系统运行所需的高能 耗，以及有效降低因开放式养殖产生的污染物对海洋环境造成的破坏。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的目的是提供一种可控式半开放的养殖舱系统，以解决上述现有技术存在的问题，能够有效降低因封闭循环水养殖系统运行所需的高能耗，以及有效降低因开放式养殖产生的污染物对海洋环境造成的破坏。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
如图1-5所示，本实施例提供一种可控式半开放的养殖舱系统，包括养殖舱11、进水机构、过滤机构和出鱼管13，进水机构包括进水管14和多根高压进水管1，进水管14位于养殖舱11的上部一侧，多根高压进水管1沿养殖舱11的顶部周向分布，高压进水管1的末端连接有伸入养殖舱11内的射流管2；养殖舱11的底部设置有过滤机构，过滤机构的出 口端位于外界海水中；养殖舱11的舱壁上设置有出鱼管13，出鱼管13上安装有可启闭的闸阀12。
进水管14为养殖舱11提供水源基体，高压进水管1为射流管2提供压力水，射流管2为养殖舱11内部流场建立提供能量，控制流速，适合鱼类生长。养殖舱11底部设置的过滤机构，对养殖舱11内的废弃物进行过滤和排放后流入到海水中。当出鱼管13上的闸阀12打开，成鱼随着水流进入出鱼管13，出鱼管13为捕鱼通道，闸阀12控制出鱼管13的通断。
于本实施例中，养殖舱11壁面周围安装进水管14和射流管2，进水管14上设置有水泵，水泵用于泵取水源；高压进水管1上也安装有水泵；射流管2沿养殖舱11的内壁竖直向下设置，射流管2上均布有射流孔。进水管14为养殖舱11供水，射流管2控制流向，适合鱼类生长；射流管2为养殖舱11内部流场提供能量，射流管2的孔口角度控制水流方向。
于本实施例中，养殖舱11底部装有倒立的圆台状细滤网3，滤网下部边缘安装环形集污槽4，环形集污槽4上部装有粗滤网(防止鱼进入排污系统)，舱内流水通过滤网的细网孔与海洋进行水交换。当养殖舱11内部产生颗粒直径大小不一致废弃物时，小颗粒废弃物在重力作用下通过细滤网网孔排放进入海水中，大颗粒废弃物经粗滤网沉降至底部环形集污槽4。
于本实施例中，养殖舱11的底部倾斜度为3°～7°。环形集污槽4与排污管道5相通，排污管道5串联输送泵7，排污管道5末端与固液分离机8相连接，固液分离机8配备固体出口9与液体出口10。当输送泵7工作时，大颗粒废弃物通过排污管道5进入固液分离机8，固体废弃物在液体中沉降，并在转鼓高速旋转产生的离心力作用下，进行固液分离。被分离的固体废弃物由固体出口9排出，水由液体出口10排出。
为防止固液分离不及时导致的排污系统压力升高，在固液分离机8入口处设置溢液管6，溢液管6连通环形集污槽4，保证系统的安全。
本发明中的可控式半开放的养殖舱系统，闸阀12由电动或手动控制，输送泵7由电机带动，固液分离机8由电机带动。
本发明中可控式半开放的养殖舱系统，养殖舱11内部流场可控，无需循环水及水处理系统，养殖舱11半开放结构，底部与海水相通，废弃 物排放可控，环境污染降低，经过分离的固体废弃物可以制造有机肥料；该养殖舱11系统能够提高养殖水平，拓展深远海海洋养殖空间利用率，为发展深远海养殖模式起示范作用。
需要说明的是，对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内，不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
本发明中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
