Description

Technical Field

[0001] This invention belongs to the technical field of underwater target acoustic characteristics, and in particular relates to a high-pressure water-filled branched underwater acoustic composite corner reflector structure. Background Technology

[0002] Corner reflectors are commonly used in radar and sonar fields as decoys and markers. Corner reflectors come in two forms: flexible reflective surfaces and solid metal plate reflective surfaces. When the reflective surface is made of flexible material, a supporting frame is needed to fix the flexible material and form the corner reflector structure. In the radar field, inflatable frames are more commonly used. For example, Chinese patents CN201821441199.1 and CN202211480420.5 respectively use inflatable frames to form multifaceted corner reflectors.

[0003] When used at sea, inflatable radar corner reflectors float on the water surface. When used underwater as acoustic corner reflectors, counterweights are required to keep the corner reflectors afloat. If the corner reflector is large, the counterweight will be very heavy, which will make deployment difficult. Summary of the Invention

[0004] In view of this, in order to solve the problem mentioned in the background art that the existing inflatable skeleton corner reflector requires the addition of a weight for underwater use, which causes inconvenience, the present invention proposes a high-pressure water-filled branch-deployment type underwater acoustic combined corner reflector structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure water-filled branched underwater acoustic combined corner reflector structure, comprising a six-way connector, high-pressure water hoses, a switch valve, a check valve, a sealing head, a fastening rope, and a reflective cloth. The six joints of the six-way connector are respectively tightly connected to six high-pressure water hoses. The other end of four of the six high-pressure water hoses is connected to the sealing head, the other end of the other high-pressure water hose is connected to the switch valve, and the other end of the last high-pressure water hose is connected to the check valve. After the six high-pressure water hoses are filled with water, they form six columnar structures. Each pair of adjacent columns is perpendicular to each other. The fastening rope connects the top of each pair of columns, forming an isosceles right triangle. The two columns are the right-angled sides, and the fastening rope is the hypotenuse. The reflective cloth is fixed inside the isosceles right triangle to form the reflective surface of the corner reflector.

[0006] Furthermore, the high-pressure water hose is tightly connected to the connector using 304 stainless steel clamps.

[0007] Furthermore, the acoustic reflective cloth is an air-insulated flexible acoustic reflective cloth or a hollow glass microsphere-insulated flexible acoustic reflective cloth.

[0008] Furthermore, a long strip of material is attached to the high-pressure water hose, and the material of the strip is the same as that of the high-pressure water hose. The strip has evenly distributed threading holes, and the acoustic reflector cloth has evenly distributed threading holes around its perimeter. The elastic band alternately passes through the threading holes on the acoustic reflector cloth and the strip to connect the acoustic reflector cloth to the water hose. The elastic band also passes through the threading holes on the acoustic reflector cloth and wraps around the fastening rope to connect the acoustic reflector cloth to the fastening rope.

[0009] Furthermore, the high-pressure water hose is a polyester filament-polyurethane flexible water hose, a PE double-layer composite flexible water hose, or a PVC coated flexible water hose.

[0010] Furthermore, the switching valve is a 304 stainless steel high-pressure miniature ball valve; the six-way connector is a 304 stainless steel high-pressure six-way connector; the check valve is a 304 stainless steel high-pressure one-way valve; and the sealing head is a 304 stainless steel high-pressure sealing head.

[0011] Furthermore, the fastening rope is a nylon rope.

[0012] Furthermore, when stored, the high-pressure water hose is folded. When in use, water is first injected through the check valve. As the water volume gradually increases, all the high-pressure water hoses unfold in sequence. When the water pressure inside the high-pressure water hose reaches the predetermined pressure, the water injection is stopped, the reflector's support structure unfolds, and the acoustic cloth unfolds into a flat surface along with the support structure.

[0013] Furthermore, after use, open the valve to drain the water from the high-pressure water hose before storing it.

[0014] Compared with the prior art, the beneficial effects of the high-pressure water-filled branched unfolding underwater acoustic combined corner reflector structure of the present invention are:

[0015] (1) The high-pressure water hose used in this invention can be folded or rolled up, and has a small volume after storage. The overall structure is lightweight, making it convenient for transportation and storage.

[0016] (2) The present invention adopts a water-filled unfolding to form a combined corner reflector structure, which does not require on-site assembly during use, saving labor costs and is highly efficient;

[0017] (3) Since the main support of the present invention is a water-filled structure, the density of the overall combined corner reflector is approximately the same as that of water, which can be easily submerged and floated in water, avoiding the inconvenience of adding a large amount of counterweight to the inflatable structure.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] See Figure 1-4 This embodiment describes a high-pressure water-filled, branching, deployable underwater acoustic combined corner reflector structure, comprising a six-way connector 1, high-pressure water hoses 2, a switching valve 3, a check valve 4, a sealing head 5, a fastening rope 6, a reflective cloth 7, and a side strap 8. The six connectors 1 are tightly connected to six high-pressure water hoses 2. Four of the six high-pressure water hoses 2 are connected at one end to the sealing head 5, one end to the switching valve 3, and the other end to the check valve 4. When filled with water, the six high-pressure water hoses 2 form six columnar structures, with each pair of adjacent hoses perpendicular to each other. The fastening rope 6 connects the tops of each pair of hoses, forming an isosceles right triangle, where the two hoses are the legs and the fastening rope 6 is the hypotenuse. The reflective cloth 7 is unfolded and fixed inside the isosceles right triangle, forming the reflective surface of the corner reflector.

[0026] The high-pressure water hose 2 is preferably a polyester filament-polyurethane flexible water hose, a PE double-layer composite flexible water hose, or a PVC coated flexible water hose. A long strip of side strap 8 is attached to the high-pressure water hose 2. The side strap 8 is made of the same material as the high-pressure water hose 8, and has evenly distributed threading holes. Threading holes are also evenly distributed around the perimeter of the acoustic reflector cloth 7. An elastic band alternately passes through the threading holes on the acoustic reflector cloth 7 and the side strap 8 to connect the acoustic reflector cloth 7 to the high-pressure water hose 2. The elastic band then passes through the threading holes on the acoustic reflector cloth 7 and wraps around the fastening side rope 6 to connect the acoustic reflector cloth 7 to the fastening side rope 6.

[0027] The connection between the high-pressure water hose 2 and the switch valve 3, the six-way connector 1, the check valve 4, and the sealing head 5 is a sealed connection. Preferably, the high-pressure water hose 2 is tightly connected with 304 stainless steel clamps after being fitted onto the connector.

[0028] The sound-reflecting cloth 7 is unfolded and fixed. Preferably, a high-elastic elastic band is alternately passed through the threading holes on the sound-reflecting cloth and the water hose to connect the sound-reflecting cloth and the water hose. The high-elastic elastic band is passed through the threading holes on the sound-reflecting cloth and wrapped around the fastening rope to connect the sound-reflecting cloth and the fastening rope.

[0029] Example 1:

[0030] The switching valve 4 is preferably a 304 stainless steel high-pressure miniature ball valve.

[0031] The six-way connector 1 is preferably a 304 stainless steel high-pressure six-way connector.

[0032] The check valve 4 is preferably a 304 stainless steel high-pressure one-way valve.

[0033] The sealing head 5 is preferably a 304 stainless steel high-pressure sealing head.

[0034] The fastening rope 6 is preferably a nylon rope.

[0035] The acoustic reflective cloth 7 is preferably an air-insulated flexible acoustic reflective cloth or a hollow glass microsphere-insulated flexible acoustic reflective cloth, with threading holes evenly arranged around the perimeter of the acoustic reflective cloth.

[0036] like Figure 2 As shown, the high-pressure water hose 2 is folded when stored. In use, water is first injected through the check valve 4. As the water volume gradually increases, all the high-pressure water hoses 2 unfold sequentially. Water injection is stopped when the water pressure inside the hoses reaches the predetermined pressure. The reflector's support structure then unfolds as shown. Figure 3 As shown in the diagram, the acoustic reflector cloth 7 unfolds into a flat surface as the support structure unfolds. Figure 4 As shown. After use, open valve 3 to drain the water from high-pressure water hose 2 and then store it away.
