Mooring device and mooring system

The invention discloses a mooring device and a mooring system. The mooring device comprises an expansion connecting base and at least two first connecting plates. One side of the expansion connecting base is used for being connected with a mooring foundation, the multiple first connecting plates are all connected to the expansion connecting base, and each first connecting plate is provided with an anchor eye. According to the mooring device, the multiple first connecting plates can be connected to one mooring foundation through the expansion connecting bases, and the effect that one mooring foundation corresponds to multiple anchor eyes is achieved. Thus, only one mooring foundation needs to be installed, mooring of the multiple mooring cables or anchor chains can be completed, and the working hours and cost of engineering construction are effectively reduced. 本发明公开了一种系泊装置和系泊系统，包括拓展连接座和至少两个第一连接板。拓展连接座的一侧用于与系泊基础连接，多个第一连接板均连接在拓展连接座上，并且每个第一连接板上均设置有锚眼。本发明提供的系泊装置，多个第一连接板可通过拓展连接座连接在一个系泊基础上，实现一个系泊基础对应多个锚眼的效果。如此，仅需安装
