然而,当前人工鱼礁主要由水泥制成的空心多面体,由于体积比较大,容易在海流和风浪作用下滚动;同时,由于水泥预制件表面呈强碱性,海洋生物难以快速附着生长,这不利于人工鱼礁区的在渔业增殖和生态环境的改善。因此,如何改善人工鱼礁普遍存在抗风浪能力弱、易被风浪冲走或泥沙埋没问题,同时又能够使海洋生物在人工鱼礁上快速附着问题是渔业增殖中的难题之一。However, the current artificial fish reefs are mainly hollow polyhedrons made of cement. Due to their relatively large volume, they are easy to roll under the action of ocean currents and wind waves. At the same time, due to the strong alkalinity of the surface of the cement prefabricated parts, it is difficult for marine organisms to attach and grow quickly. It is beneficial to the fishery multiplication and the improvement of the ecological environment in the artificial fish reef area. Therefore, how to improve the artificial fish reef's common problems of weak wind and wave resistance, easy to be washed away by wind waves or buried by sediment, and at the same time enable marine organisms to quickly attach to the artificial fish reef is one of the difficult problems in fishery proliferation.

具体实施方式 Detailed ways
图1示出了本实用新型的抗风浪的生物易附着生态型人工鱼礁的一个具体实施例的结构示意图,该人工鱼礁包括底座1和固定设于底座上的塔形体,塔形体由顶面2和侧面3围括而成,为多面棱柱框架结构组成,多面体棱柱框架外两侧都含有连接环或挂耳4,通过连接环或挂耳连接悬挂物5,整个底座通过几根钢筋混凝土立柱支撑,从而形成单个人工鱼礁的三维立体网状结构。考虑到人工鱼礁在海水中易滚动和沙埋,因此,设计的人工鱼礁为梯型体,即底座1联有几根支架6垂直支撑,支架可以插入泥砂质海底,起到固定鱼礁的作用,同时,塔形体底面要比顶面面积大,这样泥沙通过顶面2极易沉降到海底,不会使大量泥沙滞留于塔形体内。同时,整个人工鱼礁表面及内部通过悬挂物连接来促进海洋生物在其表面的附着生长。Fig. 1 has shown the structure schematic diagram of a specific embodiment of the biological easy-attachment ecological type artificial fish reef of anti-wind and wave of the present utility model, and this artificial fish reef comprises base 1 and is fixed on the tower shape body that is arranged on the base, and tower shape body is formed by top Enclosed by face 2 and side 3, it is composed of a polyhedral prism frame structure. Both sides of the polyhedral prism frame contain connecting rings or hanging ears 4, through which the hanging objects 5 are connected, and the entire base passes through several reinforced concrete Supported by columns, a three-dimensional network structure of a single artificial reef is formed. Considering that the artificial reef is easy to roll and be buried in seawater, the artificial reef is designed as a trapezoidal body, that is, the base 1 is supported vertically by several brackets 6, and the brackets can be inserted into the muddy seabed to fix the reef. Effect, at the same time, the bottom surface of the tower-shaped body is larger than the top surface area, so that silt can easily settle to the seabed by the top surface 2, and a large amount of silt can not be stranded in the tower-shaped body. At the same time, the surface and interior of the entire artificial fish reef are connected by hanging objects to promote the attachment and growth of marine organisms on the surface.
人工鱼礁的为塔形体,塔形体除底座外,均为多面体棱状框架结构组成。底座1是与塔形体对应的多边形,且底座1开有通孔,其主要功能是礁体内部水交换和将沉降的泥沙冲刷至海底。每个多面体棱状框架结构中的框架内外两侧各含有多个连接环或挂耳4,通过连接物对多面体棱状框架上的连接耳或挂耳进行连接。其中,连接物主要是尼龙类的绳子及其编织物、渔网网片,连接环或挂耳主要是双耳高强度塑料、渔具、渔网、钢筋水泥预制件、绳索等。The artificial reef is in the shape of a tower, and the tower is composed of a polyhedral prismatic frame structure except for the base. The base 1 is a polygon corresponding to the tower body, and the base 1 has a through hole, and its main function is to exchange water inside the reef body and to wash the settled sediment to the seabed. The inner and outer sides of the frame in each polyhedral prismatic frame structure respectively contain a plurality of connecting rings or hanging ears 4, and the connecting ears or hanging ears on the polyhedral prismatic frame are connected through connectors. Among them, the connectors are mainly nylon ropes and their braids, fishing net mesh, and the connecting rings or lugs are mainly binaural high-strength plastics, fishing gear, fishing nets, reinforced concrete prefabricated parts, ropes, etc.
设计时考虑人工鱼礁本身的沉降性及海洋生物不易附着的缺点,设计的这种多面体棱柱状且礁体内外呈立体网状结构的人工鱼礁。该结构组装简单,成本低,空间利用率高,人工鱼礁底座重、不易被泥沙堵塞,具有抗风浪的作用。礁体内外通过绳体等连接,呈立体网状结构表面,整个人工鱼礁的通透性好,促进内外部水交换,整个网状空间有利于海洋生物的附着生长,从而改善周边环境,让鱼类幼体可以在其中潜伏、自由穿梭,提高聚鱼量。经过模型试验及数值模拟,改生态型人工鱼礁,适于投放至水深5-20米的海域,不会发生倾覆移位,有利于大量藻类、贝类、苔藓虫、等快速在人工鱼礁上附着生长,可为刺参、石斑鱼等隐匿生物提供安全可靠的栖息地和饵料场,适于大中小型鱼类的穿梭停留,流场效应较好,且抗风浪,具有较好的经济效益,因此可以广泛应用于人工鱼礁的建设中。Considering the subsidence of the artificial reef itself and the disadvantages that marine organisms are not easy to attach during the design, the artificial reef is designed with a polyhedral prism shape and a three-dimensional network structure inside and outside the reef. The structure is simple to assemble, low in cost, high in space utilization, heavy in the base of the artificial reef, not easily blocked by sediment, and has the effect of resisting wind and waves. The inside and outside of the reef are connected by ropes, etc., showing a three-dimensional mesh structure surface.
