The invention relates to a crossed three-dimensional
torpedo interception net capable of intercepting torpedoes, especially a
torpedo interception net which can be projected or cast and can outspread automatically when entering into the water to form a decussate three-dimensional
torpedo interception net. The appearance is column-shaped, a top cover is arranged at the top part and is fixed and sleeved by bayonet locks on the casing which is divided into four sections, the
specific density of the top part is lighter than the
seawater and the
specific density of the bottom part is heavier than the
seawater. A decussate bracket is arranged inside, a telescopic link is connected on the lateral side, and a suspended net is connected with the telescopic link via a hanger. When the torpedo interception net is projected or cast into sea via a surface ship, a
submarine or a helicopter, the top cover is ejected via a spring, the casing is opened, a going barren dives the telescopic link to expand and the suspended net is dragged to outspread in horizontally. Under the upward pulling force of the telescopic link and the downward pulling force of the weight of the connector of the suspended net, the suspended net is outspreaded along vertical direction; a stabilization membrane connected with the inner side of the suspended net control the stability of the torpedo interception net along the vertical direction.
