The sea wave on the sea surface is basically stirred in a wave shape all the time, so that the communication equipment is irregularly rocked along with the sea wave on the sea surface in the three-dimensional direction. This scheme communication equipment realizes its vertical, horizontal direction's buffering offset through the antidetonation subassembly 4 that circumference set up, and the bottom sets up buffering base 3 and realizes whole buffering that rocks, and the fluctuation unit 5 of outside circumference setting further offsets the range of rocking, increases communication equipment's sea interference killing feature, reduces its direct impact force of inner structure and realizes self accurate positioning's function simultaneously.

Because the conventional spring 43 and other buffering modes can only buffer impact force in a single vertical direction or a horizontal direction, the vertical direction and the horizontal direction are difficult to buffer at the same time, and even irregular shaking is difficult to realize, because the two ends of the spring 43 are fixed, the buffering acting force direction is basically unchanged, and therefore, better buffering anti-interference effect on large-amplitude sea shaking is difficult to realize.

The scheme sets up antidetonation subassembly 4, it includes extension board 41, slide 42, spring 43, and the bottom and the buffering base 3 of extension board 41 link to each other, and its outside slope is arranged and has been seted up guide rail groove 7, and the corresponding side of slide 42 is corresponding slope arrangement with it, and the one end of spring 43 is connected with the inboard end connection of extension board 41, and the other end is connected with the corresponding side end connection of extension board 41, and the middle part of slide 42 is connected with slider 8, slider 8 and guide rail groove 7 sliding connection.
