[0048] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, this embodiment introduces a towable offshore mobile target, including: a first target 10; a second target 20, the first target 10 and the second target 20 are connected via a plug-in structure 40; a controller, the controller and the plug-in structure 40 are electrically connected, and the controller is used to control the plug-in structure 40 to disconnect the connection between the first target 10 and the second target 20.

[0050] Furthermore, this embodiment provides two targets, a first target 10 and a second target 20. Depending on the status of the first target 10 and the second target 20, the operator controls the plug-in structure via a controller to disconnect the first target 10 and the second target 20, thereby anchoring one of the targets. This embodiment, by providing two targets, the first target 10 and the second target 20, eliminates the need for frequent target replacement during training and eliminates the need for manual disassembly and replacement, thereby ensuring personnel safety and improving the efficiency of practical training.

[0051] Preferably, Figure 1 As shown, the towable offshore mobile target includes a towing rope 30; a plug-in structure 40 is arranged on the first target 10; the first end of the towing rope 30 is connected to the second target 20, and the second end of the towing rope 30 is sleeved on the plug-in structure 40, and the controller is used to control the movement of the plug-in structure 40 so that the second end of the towing rope 30 is disengaged from the plug-in structure 40.

[0052] Further, if Figure 1As shown, the first end of the traction rope 30 refers to the left end of the traction rope 30, and the second end of the traction rope 30 refers to the right end of the traction rope 30. In this embodiment, the traction rope 30 is an ultra-high molecular weight polyethylene cable. The length L of the traction rope 30 can be set according to the usage situation. In this embodiment, the length L of the traction rope 30 is 50 meters.

[0053] Preferably, Figure 2 As shown, the plug-in structure 40 includes a base, an insertion rod and a driving member; the base and the driving member are both arranged on the first target 10, the insertion rod and the driving member are connected, and the second end of the traction rope 30 is sleeved on the insertion rod; a socket is provided on the base, and the insertion rod is inserted into the socket; the controller and the driving member are electrically connected.

[0054] Furthermore, when the controller controls the driving member to drive the insertion rod to be inserted into the socket, the first target 10 and the second target 20 are connected together by the traction rope 30; when the controller controls the driving machine to drive the insertion rod to gradually shorten, the insertion rod is separated from the socket. As the insertion rod is further shortened, the traction rope 30 is separated from the insertion rod, and the connection between the first target 10 and the second target 20 is disconnected.

[0055] Preferably, in this embodiment, the driving member is a telescopic motor.

[0056] Preferably, Figure 2 As shown, the base includes a first base and a second base; the first base and the second base are arranged parallel to each other, the first base is provided with a first socket, the second base is provided with a second socket, the first socket, the second socket and the insertion rod are coaxially arranged; the insertion rod passes through the first socket and the second socket, and the second end of the traction rope is located between the first socket and the second socket.

[0057] Furthermore, when the controller controls the driving member to drive the insertion rod to pass through the first hole and the second hole in sequence, the first target 10 and the second target 20 are connected together by the traction rope 30; when the controller controls the driving machine to drive the insertion rod to gradually shorten, when the insertion rod is separated from the first hole, it is restricted by the first base, the traction rope 30 is separated from the insertion rod, and the connection between the first target 10 and the second target 20 is disconnected.

[0058] Preferably, the controller and the remote terminal are connected by wireless communication, and the controller is used to receive instructions from the remote terminal to control the plug-in structure 40 to disconnect the connection between the first target 10 and the second target 20.

[0059] Furthermore, in this embodiment, the remote terminal controls the movement of the plug-in structure through the controller to anchor the first target 10 or the second target 20 without manual disassembly and replacement, thereby ensuring personnel safety and improving the efficiency of actual combat training.

[0060] Furthermore, in other embodiments, a timing module may be provided in the controller, and the controller controls the movement of the plug-in structure at a fixed time to anchor the first target 10 or the second target 20 .

[0061] Preferably, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the towable offshore mobile target includes a towing frame 50 ; a first end of the towing frame 50 is connected to the first target 10 , and the plug-in structure 40 is provided at a second end of the towing frame 50 .

[0062] Furthermore, the first end of the traction frame 50 refers to the right end of the traction frame 50 , the second end of the traction frame 50 refers to the left end of the traction frame 50 , and the second end of the traction frame 50 is provided with two plug-in structures 40 .

[0063] Preferably, a driver 11 is provided on the first target 10 ; the driver 11 is wirelessly connected to the remote terminal, and the driver 11 is used to receive instructions from the remote terminal to drive the first target 10 to drive the second target 20 to move.

[0064] Furthermore, the remote terminal can remotely control the driver 11 to drive the first target 10 to drive the second target 20 to navigate along a certain route, thereby improving the practical training function and efficiency.

[0065] Further, a plurality of small floats are provided on the traction rope 30, and the plurality of small floats are evenly arranged along the length direction of the traction rope 30. The plurality of small floats can keep the traction rope 30 always floating on the sea surface to prevent it from being stirred into the driver 11 due to wind and waves.

[0066] Preferably, Figure 9 As shown, the towed mobile offshore target includes an infrared heat source device 60; the infrared heat source device 60 is arranged on the first target 10 and / or the second target 20; the infrared heat source device 60 and the remote terminal are remotely communicated and connected, and the remote terminal remotely controls the opening and closing of the infrared heat source device 60.

[0067] Furthermore, to better simulate the infrared signature of a ship, the first target 10 and / or the second target 20 are equipped with one or more specially developed infrared heat source devices 60 that can be remotely controlled to open and close. This infrared heat source has multiple activation modes to adapt to various environments under different conditions. Ignition can be remotely controlled by electric ignition or manually, and it also has a temperature indicator feedback function. In remote ignition mode, an ignition signal from a remote terminal is transmitted via the 4G network to the heat source box control system on the infrared heat source device 60, which then executes the ignition command. During normal operation, the heat source box maintains a temperature of no less than 175°C. Because the heat source box is equipped with a 5 kg gas tank, it can operate normally for no less than 2.5 hours. The calorific value of the infrared heat source can be adjusted remotely within a range of 1K to 5K. If necessary, the infrared heat source device 60 can be configured with a dual-burner structure to significantly increase infrared radiation and simulate the infrared signature of a target with higher heat output.

[0068] In order to ensure the stability of the infrared heat source device 60 when the first target 10 or the second target 20 is in a shaking state, a stable state balance frame can be added outside the infrared heat source device 60 to ensure that when the first target 10 or the second target 20 is shaken by waves and sea breeze, the burner head of the infrared heat source device 60 is always facing upward, thereby improving the safety and reliability of the infrared heat source device 60.

[0069] Preferably, the first target 10 and / or the second target 20 includes a first buoy 21 and a second buoy 22 ; the first buoy 21 and the second buoy 22 are arranged in parallel, and the first buoy 21 and the second buoy 22 are filled with high-molecular high-density polyester fiber material.

[0070] Furthermore, in this embodiment, if Figure 1 As shown, the first target 10 and the second target 20 both adopt a catamaran structure design, which can increase the seaworthiness of the first target 10 and the second target 20.

[0071] Further, if Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the weight of the second target 20 is evenly distributed on the first buoy 21 and the second buoy 22 on both sides. The center of gravity of the second target 20 is closer to the center of the second target 20 and lower, and the stability is improved by 35%. The seaworthiness range is expanded by 1.5 times compared with that of an ordinary single-hull ship. The deployment resistance is reduced and the speed is increased by 10%. At the same time, the stability of the second target 20 is increased under complex sea conditions. The overall structure of the second target 20 can be kept stable under level 7 winds and 2-meter-high waves without capsizing. Under the same gravity conditions, the catamaran structure has a shallower draft than a single-hull ship, which is conducive to the rapid deployment of towed offshore targets. After deployment, it is anchored in the designated sea area and subjected to the test of weapons and equipment.

[0072] Further, if Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the first and second buoys 21, 22 are filled with high-density polyester material, which prevents water leakage due to impact or cracking. Even if they accidentally hit a reef, they will not capsize or even sink due to water ingress, improving safety by 42%. Because polyester fiber is inherently lightweight, it does not significantly increase the total weight of the second target 20 and increase the difficulty of towing, effectively improving the safety of the second target 20.

[0073] For example, during target test training, the first buoy 21 or the second buoy 22 was hit. Because the filling high-molecular polyester fiber provided sufficient buoyancy reserve, the second target 20 was not affected at all and the next wave of strike training could be carried out.

[0074] Furthermore, the target attachments of the first target 10 and the second target 20 in this embodiment are customizable. It is understood that different target attachments can be added based on the type of guided ammunition being trained. By quickly replacing the target attachments, the first target 10 and the second target 20 can be equipped with different target simulation characteristics in a short period of time, meeting the strike requirements of different guided weapons and ammunition, achieving multiple uses for one target and reducing training costs.

[0075] This towed mobile offshore target can be moved to the target area by a towing vessel using cables to tow a first target 10 and a second target 20 in complex sea conditions. If one target is destroyed, the operator can remotely control the plug-in structure 40 via a remote terminal to anchor the destroyed target, without affecting the secondary target shooting mission and improving safety. The target bodies of the first target 10 and the second target 20 can be customized to meet different needs. They can simulate ship radar and laser signatures, and can also simulate ship infrared signatures through a built-in remotely controlled infrared heat source device 60, meeting the practical training requirements of precision-guided munitions in various guidance modes.
