Description

An in-situ self-expanding underwater camouflage body

technical field

The invention belongs to the field of marine camouflage protection, and relates to the technology of water-absorbing swelling materials, in particular to an in-situ self-expanding underwater camouflage body.

Background technique

The underwater battlefield is the stage for mine warfare and anti-mine warfare, submarine warfare and anti-submarine warfare, and it also includes underwater unmanned platform operations, underwater information surveillance and intelligence reconnaissance, underwater acoustic countermeasures, underwater information transmission and command and control Wait.

In recent years, the underwater battlefield, as a key point for military powers to maintain their military advantages, has gradually become more prominent in information-based naval warfare. Various maritime military powers have promoted and implemented strategies and plans related to marine underwater warfare, and continuously strengthened their combat capabilities. The control of the underwater battlefield space, and a variety of underwater combat modes have been demonstrated based on different mission and task systems, and a large number of underwater weapons and equipment have been developed.

Since sound is the only carrier that can effectively transmit information over long distances in the ocean, the equipment for underwater warfare is mainly sonar. Among them, sonar can obtain underwater information, guide underwater weapons to achieve precise strikes, and is also an important equipment for underwater surveillance, information transmission, command and control, and underwater acoustic information countermeasures.

Therefore, the current domestic and foreign research on improving underwater combat performance is basically improving the performance of the weapon itself to achieve acoustic stealth. However, these stealth technologies cannot effectively eliminate the threats brought by detection technologies, and new stealth technologies need to be developed urgently. Therefore, it is proposed to use camouflage technology to develop an in-situ underwater self-expanding camouflage body, which can form similar protections according to actual needs, such as submarines, mines, seabed sediments, etc., and mislead the existing underwater identification technology. Protect underwater targets and better meet the requirements of underwater combat and underwater information monitoring.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an in-situ self-expanding underwater camouflage body, which can realize camouflage functions such as concealment, false display and avoidance, so as to achieve the purpose of effectively protecting underwater targets.

The technical scheme that the present invention solves technical problem adopts is:

An in-situ self-expanding underwater camouflage body, including an outer cover body and a shaped expansion body. The outer cover body is made of a three-layer structure, which is a forming restraint layer, an acoustic wave reflection layer, and an inner lining layer from outside to inside. , the shaped expansion body is a water-absorbing foaming expansion resin, and water-permeable channels are evenly distributed on the binding layer, the sound wave reflection layer and the inner lining layer. The water required for forming the expansion body is connected by the voids (pores) of each layer of fabric and adhesive, and introduced by siphon and water absorption, and then foamed and swollen, and shaped according to the specified shape of the constraint.

Furthermore, an attitude stabilizer is embedded in the molded expansion body.

Moreover, the posture stabilizing body is fixed on the inner liner.

Moreover, the posture stabilizing body is a high-density metal bead, and the high-density metal bead is covered with an outer cover fabric, and the outer cover is connected with the inner lining layer.

Moreover, the binding layer, the sound wave reflection layer and the inner lining layer are all hydrophilic and water-permeable textile materials.

Moreover, the shape-binding layer adopts high-strength polyester asymmetric fabric, preferably, asymmetric polyetherester elastic fiber fabric.

Moreover, the said sound wave reflection layer is made of salt corrosion resistant metal fiber fabric, preferably stainless steel fiber blended fabric.

Moreover, the inner lining layer adopts non-woven fabric.

Moreover, the water-absorbing foaming expansion resin is preferably polyacrylic water-absorbing resin.

Moreover, the shape-constraining layer, the acoustic wave reflection layer, and the inner liner are bonded by water-permeable adhesives or connected by sewing.

Advantage and positive effect of the present invention are:

The in-situ self-expanding underwater camouflage body of the present invention can spontaneously expand in-situ and quickly form camouflage software similar to a target protection object. On the one hand, it can interfere with the existing underwater acoustic detection technology and mislead it; on the other hand, it can effectively cover up the movement "traces" of the target protection object, and realize camouflage functions such as concealment, false display and evasion, so as to effectively protect the underwater environment. The purpose of the next target.

Detailed ways

Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not limiting, and the protection scope of the present invention cannot be limited by the following examples.

An in-situ self-expanding underwater camouflage body, including an outer cover body and a shaped expansion body 6. The outer cover body is made of a three-layer structure, which is sequentially formed from the outside to the inside. Lining layer 2. The shaped expansion body is covered by an inner liner, and a posture stabilizing body 3 is embedded in the shaped expansion body, and the posture stabilizing body is fixed on the inner liner. The formed expansion body is a water-absorbing foaming expansion resin (polyacrylic water-absorbing resin), the binding layer, the sound wave reflection layer and the inner lining layer are all hydrophilic and water-permeable textiles, and the posture stabilizing body is a high-density metal beads.

The voids (pores) evenly distributed on the binding layer, the acoustic wave reflection layer, the inner lining layer and the adhesive are water-permeable channels; the formed expansion body foams and swells after contacting the water introduced by the water-permeable channel, and then forms according to the shape specified by the constraint. The attitude stabilizing body is sewn on the inner lining layer at the bottom of the camouflage body.

The shape-binding layer is preferably a high-strength polyester asymmetric fabric (asymmetric polyether ester elastic fiber fabric), and the sound wave reflection layer is preferably a salt-resistant metal fiber fabric (stainless steel fiber blended fabric), both of which have the same shape, and use water-permeable Adhesive bonding.
