Description

Technical Field

[0001] The present invention relates to the technical field of underwater vehicle recovery, and in particular to a pop-up buoy positioning and recovery device and a recovery method for underwater vehicles. Background Art

[0002] In the new era, all countries in the world have strengthened their attention to the ocean. 71% of the world's area is covered by the ocean, and the ocean's resource reserves are also very rich. Human exploration of the ocean has never stopped. As an important weapon for exploring the ocean and attacking underwater and surface targets, underwater vehicles have become increasingly important. Experimental research on various types of underwater vehicles is also an important stage in the development of underwater vehicles. Underwater, due to the unclear underwater hydrological conditions and the difficulty of long-distance communication underwater, it is very difficult to recover underwater vehicles and experimental data.

[0003] At present, there are several ways to locate underwater vehicles, including sonar detection, releasing dyes, setting strobe lights, etc. Obviously, the first method is greatly limited by professional equipment, and the underwater environment is complex, making it difficult to detect small objects. The second and third methods are greatly affected by the environment and climate, and the underwater light transmittance is poor and visibility is low, making it difficult to play the role of positioning.

[0004] Among the existing patent technologies, patent number CN114084284 is a highly reliable integrated underwater vehicle positioning buoy, which can pop up the buoy and float on the water surface according to the experimental requirements, showing the position of the underwater vehicle model. However, this device can only be used for positioning, not for recovery, and the delay time is difficult to determine. If it is popped up too early, the speed of the vehicle will be too fast, which will cause the spinning rope to break; if it is popped up too late, the tail part will be stuck in the mud, causing the pop-up buoy to fail to work normally, positioning failure, and it is difficult to effectively realize the positioning function. Summary of the invention

[0005] In order to address the deficiencies in the prior art, the present invention proposes a pop-up buoy positioning and recovery device and recovery method for underwater vehicles, which is used for underwater vehicles entering the water at high speed, is less affected by the environment, can quickly find and recover the underwater vehicles, has a simple and compact structure, and is highly reliable, and can meet the needs of positioning and recovering various types of underwater vehicles.

[0006] The technical solution of the present invention is:

[0007] The pop-up buoy positioning and recovery device for underwater vehicles is characterized by comprising a navigation body positioning and recovery compartment 1, a circuit board compartment 5, a buoy 2, a lifting eye screw 4, a load-bearing hook 3, and a steel wire rope 16;

[0008] The circuit board compartment 5 is provided with a trigger circuit board 8, a battery 10, a watertight plug 7, an ignition head 14, and a cartridge case 13. The trigger circuit board 8 is used to control the buoy to pop out, and the battery 10 is used to supply power to the trigger circuit board 8. The cartridge case 13 is screwed on the circuit board compartment 5, and a cartridge case rear cover 15 is installed at its tail end. The ignition head 14 and gunpowder are placed in the cartridge case 13, and the positive and negative poles of the ignition head 14 are led out and connected to the trigger circuit board 8 through a wire to form a circuit system.

[0009] The buoy 2 is provided with a nylon rope 17, which is a winding-shaped line column, one end of which is fixed on the buoy 2, and the other end of which is fixed on the load-bearing hook 3;

[0010] The watertight plug 7 is connected to the circuit board compartment cover 6 by threads, and the watertight plug 7 serves to power the trigger circuit board 8;

[0011] The load-bearing hook 3 is connected to the eye screw 4 through a steel wire rope 16, and the eye screw 4 is connected to the navigation body through a thread to position the recovery compartment 1.

[0012] A further technical solution of the present invention is: the battery 10 is fixed to the battery mounting plate 11 through the battery fixing cover 12, the battery mounting plate 11 is mounted on the trigger circuit board 8 through the isolation column 9, and the trigger circuit board 8 is mounted on the circuit board compartment cover 6 through the isolation column 9.

[0013] A further technical solution of the present invention is: the trigger circuit board 8 has an accelerometer built in, which together with the circuit board cabin 5 constitutes a trigger system for positioning the buoy, energizes the ignition head 14, ignites the gunpowder in the powder bag, and pops out the buoy 2.

[0014] The pop-up buoy positioning and recovery method for an underwater vehicle comprises the following steps:

[0015] Step 1: After setting the delay time for the trigger circuit board and powering it on, launch the vehicle at high speed;

[0016] Step 2: The navigation body ends its navigation and falls freely in the water. After it falls to the bottom of the water, the circuit board 8 is triggered to energize the ignition head 14, igniting the gunpowder to eject the buoy 2, and the buoy 2 quickly floats to the water surface;

[0017] Step 3: After the surface salvage personnel find the buoy 2, they sink the salvage ring 18 along the aramid rope 17 to the vicinity of the underwater vehicle, and try to pull it up and hook it on the load-bearing hook 3 several times;

[0018] Step 4: The surface salvage personnel pull up the salvage ring 18, and use the salvage ring 18 to pull the aircraft to the surface of the water to achieve recovery.

[0027] like Figure 1 As shown, the pop-up buoy positioning and recovery device of the present invention includes a navigation body positioning and recovery compartment 1, a circuit board compartment 5, a buoy 2, a lifting eye screw 4, a load-bearing hook 3, and a steel wire rope 16.

[0028] The circuit board cabin 5 is provided with a trigger circuit board 8, a battery 10, a watertight plug 7, an ignition head 14, and a cartridge shell 13, which constitute the trigger system of the device of the present invention and are used to sequentially energize the ignition head 14. The accelerometer on the trigger circuit board 8 reaches the set trigger acceleration due to the large thrust during the launch process, and the trigger circuit board 8 program is started. After a preset period of time, the ignition head is energized and ignited, and the rear cover 15 of the cartridge shell is ruptured under pressure, forming a high pressure between the circuit board cabin 5 and the buoy 2, popping out the buoy 2, and at the same time bringing out the load-bearing hook 3, and then the spinning rope 17 is unfolded, and the buoy 2 floats to the surface due to the buoyancy, realizing the positioning of the underwater vehicle.

[0029] like Figure 3 The schematic diagram of the pop-up buoy positioning and recovery method for underwater vehicles of the present invention is shown in FIG. When the buoy 3 floats to the water surface, the salvage personnel take the salvage boat to pick up the buoy 2, tie the salvage ring 18 with a rope, and sink it to the vicinity of the underwater vehicle along the spinning rope 17. At this time, the salvage ring 18 is pulled up several times until the salvage ring 18 hooks the load-bearing hook 3, and then the salvage ring 18 is pulled up together with the vehicle to achieve the recovery of the underwater vehicle.
