Description

Technical Field

[0001] This utility model relates to the field of inflatable targets, and more particularly to an inflatable marine target. Background Technology

[0002] Inflatable targets are made of high-strength, flexible materials such as nylon and rubber. They are devices that inflate to form the shape of targets such as aircraft and ships. Inflatable targets are widely used at sea because of their significant cost-effectiveness. Compared with physical targets, they greatly reduce manufacturing, maintenance, and transportation costs. They are also extremely flexible and convenient to deploy. When not inflated, they are small and easy to transport. They can be quickly deployed at designated locations at sea and can accurately simulate various maritime targets, providing realistic objects for maritime combat training to improve training effectiveness. They also have high safety performance, effectively reducing the safety risks and accidental losses of live-fire training at sea.

[0003] Existing inflatable targets at sea operate by using electric or manual air pumps to inflate the target, which is made of flexible materials such as nylon-coated fabric, through air pipes. The target expands into a simulated target shape due to the increased internal air pressure. To ensure floating and stability, the bottom or interior is equipped with buoyancy devices such as airbags and foam plastics. Some are also equipped with ballast systems to optimize the center of gravity. The target is positioned by anchoring systems and GPS. The former is fixed to the seabed by anchor chains and anchors to resist external forces, while the latter monitors the position in real time to ensure that the target remains in the designated location. The target simulates real maritime targets in terms of visual, electromagnetic, and infrared characteristics by means of precise shape design, special surface coating, and electronic equipment such as radar reflectors and infrared radiation sources.

[0004] In the actual use of inflatable targets at sea, there is a rather thorny problem. Currently, the counterweight and the floating target need to be placed at the same time during storage, which brings great trouble. Because the counterweight is large and heavy, and the floating target still has a certain volume even after being deflated, the coexistence of the two occupies a lot of space. On ships and other vehicles where space is already extremely valuable, such a huge footprint greatly affects the rational use of storage space. Moreover, before each training mission at sea, a lot of manpower and time are spent moving and placing the two, which seriously affects the convenience of deploying inflatable targets at sea and significantly hinders the improvement of training efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a marine inflatable target, which aims to improve the problem of excessive floor space caused by the need to store the counterweight and the floating target at the same time during equipment use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a marine inflatable target, comprising a float target, wherein a plurality of connecting blocks are fixedly connected to the outer wall of the float target, a counterweight assembly is provided at the bottom of the float target, a connecting rod is slidably connected inside each connecting block, a limiting plate is fixedly connected to one end of each connecting rod, a spring is provided on the outer wall of each connecting rod, one end of each spring is fixedly connected to the inside of the connecting block, the other end of each spring is fixedly connected to one side of the limiting plate, and a fixing assembly is provided at one end of each connecting rod;

[0007] Each of the fixing components includes a limiting rod and a fixing rod. The bottom end of each limiting rod is fixedly connected to the top of the connecting rod, and the bottom of each fixing rod is fixedly connected to the top of the limiting rod. One end of each fixing rod is slidably connected inside the connecting block.

[0008] As a further description of the above technical solution:

[0009] The counterweight assembly includes multiple counterweight ropes and counterweight blocks. The top end of each counterweight rope is slidably connected to one side of a limiting rod, and the bottom end of each counterweight rope is fixedly connected to the top of a counterweight block. The top of the counterweight block is fixedly connected to the bottom end of the counterweight rope.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the float target is fixedly connected to multiple connecting blocks II, and each connecting block II is slidably connected to multiple fixing pins.

[0012] As a further description of the above technical solution:

[0013] Each of the fixed pins has a connecting strip fixedly connected to its outer wall, and each of the connecting strips has a lever fixedly connected to its top.

[0014] As a further description of the above technical solution:

[0015] Each of the fixing pins is provided with a second spring at one end, and one end of each second spring is fixedly connected to the inside of the fixing pin, while the other end of each second spring is fixedly connected to the inside of the connecting block.

[0016] As a further description of the above technical solution:

[0017] Each of the two connecting blocks has multiple locking slots on one side and multiple connecting slots on one side.

[0018] As a further description of the above technical solution:

[0019] A connecting rope is provided on one side of the float target, and a connector is fixedly connected to one end of the connecting rope. Multiple connecting plates are fixedly connected to one side of the connector.

[0020] As a further description of the above technical solution:

[0021] The connecting plates are arranged in a symmetrical array on one side of the connector, and the outer wall of each connecting plate is slidably connected to the inside of the connecting groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, first, hold the limiting rod and pull it outward so that the fixing rod disengages from the inside of the connecting block. Then, put the loop at the top of the counterweight rope on the fixing rod. After that, release the limiting rod so that the connecting rod moves inward under the elastic force of the spring, so that the fixing rod re-locks into the inside of the connecting block. This achieves the effect of easily combining or disassembling the float and the counterweight during the use of the equipment, avoiding the problem of storing the counterweight and the float at the same time during the use of the equipment, which would result in an excessive footprint. This improves the convenience of the inflatable target at sea.

[0024] 2. In this utility model, first, hold the lever and pull it outward so that the fixing pin slides out of the connecting groove. Then, rotate the lever so that the connecting strip enters the locking groove. Then, take out the connecting rope and insert the connecting plate at its connector into the connecting groove. Then, hold the lever again and turn the connecting strip out of the locking groove so that the fixing pin springs back into the connecting groove under the action of the spring. This achieves the effect of easily connecting two floats together during equipment use, avoiding the problem of overly complicated operation when connecting two floats during equipment use, thus improving the practicality of the marine inflatable target.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of an inflatable marine target, comprising a float 1. Multiple connecting blocks 2 are fixedly connected to the outer wall of the float 1 for connecting a counterweight rope 8. A counterweight assembly is provided at the bottom of the float 1 to provide counterweight and prevent it from drifting erratically at sea. Each connecting block 2 has a connecting rod 3 slidably connected inside for connecting a limiting rod 6 and a fixing rod 7. One end of each connecting rod 3 is fixedly connected to a limiting plate 4 to limit the movement range of the connecting rod 3. A spring 5 is provided on the outer wall of each connecting rod 3 to provide elastic force, ensuring that the fixing rod 7 remains connected to the connecting block 2. One end of each spring 5 is fixedly connected inside the connecting block 2, and the other end of each spring 5 is fixedly connected to one side of the limiting plate 4. A fixing assembly is provided at one end of each connecting rod 3 to fix the counterweight rope 8, preventing it from falling off.

[0034] Each fixing component includes a limiting rod 6 and a fixing rod 7. The bottom end of each limiting rod 6 is fixedly connected to the top of the connecting rod 3, restricting the movement of the annular joint at the top of the counterweight rope 8. The bottom of each fixing rod 7 is fixedly connected to the top of the limiting rod 6, and cooperates with the connecting block 2 to form an annular lock, locking the annular joint of the counterweight rope 8 inside. One end of each fixing rod 7 is slidably connected inside the connecting block 2. The counterweight component includes multiple counterweight ropes 8 and counterweight blocks 9. The top of each counterweight rope 8 is slidably connected to one side of the limiting rod 6 for connecting the counterweight block 9. The bottom end of each counterweight rope 8 is fixedly connected to the top of the counterweight block 9, and the top of the counterweight block 9 is fixedly connected to the bottom end of the counterweight rope 8, providing counterweight to the equipment to prevent it from swaying at sea.

[0035] Specifically, when the equipment needs to be assembled and put into use, the operator first holds the limit rod 6. Then, the operator applies force evenly to pull the limit rod 6 outward. During this process, the fixing rod 7, which was originally inserted inside the connecting block 2, gradually comes out under the action of the limit rod 6. Next, the operator picks up the counterweight rope 8 and puts the loop at the top of the counterweight rope 8 onto the fixing rod 7 that has just come out. After completing this step, the operator releases his hand from the limit rod 6. At this time, the spring 5 hidden inside the equipment begins to play its role. Under the elastic force of the spring 5, the connecting rod 3 moves inward, thereby driving the fixing rod 7 to re-engage inside the connecting block 2, firmly locking the counterweight rope 8. Thus, the assembly of the equipment is successfully completed.

[0036] Reference Figure 4 and Figure 5 Multiple connecting blocks 10 are fixedly connected to the outer wall of the float target 1, and are connected to the connecting rope 17 to allow the two devices to be used in series. Multiple fixing pins 11 are slidably connected inside each connecting block 10 to fix the connecting plate 19, thus fixing it inside the connecting block 10. A connecting strip 12 is fixedly connected to the outer wall of each fixing pin 11 to connect to a lever 13 and drive the fixing pin 11 to move. A lever 13 is fixedly connected to the top of each connecting strip 12 to control the position of the fixing pin 11. A spring 14 is provided at one end of each fixing pin 11 to provide elastic force to the fixing pin 11, and simultaneously cooperates with it to fix the connecting plate 19 inside the connecting block 10. One end of each spring 14 is fixedly connected inside the fixing pin 11. The other end of the spring 14 is fixedly connected to the inside of the connecting block 10. Each connecting block 10 has multiple locking grooves 15 on one side to accommodate the connecting strip 12 and the lever 13, and to lock them so that the fixing pin 11 will not spring back. Each connecting block 10 has multiple connecting grooves 16 on one side to accommodate the connecting plate 19. A connecting rope 17 is provided on one side of the float 1 for connecting to another device. One end of the connecting rope 17 is fixedly connected to a connector 18 for fixing the connecting plate 19. Multiple connecting plates 19 are fixedly connected to one side of the connector 18, which cooperate with the connecting block 10 to connect the two devices in series. The connecting plates 19 are arranged in a symmetrical array on one side of the connector 18, and the outer wall of each connecting plate 19 is slidably connected to the inside of the connecting groove 16.

[0037] Specifically, when two devices need to be connected together for series use, the operator first holds the lever 13 and applies even force to pull it outward. During this process, the fixing pin 11, which was originally embedded in the connecting groove 16, begins to slowly slide outward under the action of the lever 13. After the fixing pin 11 is completely dislodged from the connecting groove 16, the operator begins to rotate the lever 13. The lever 13 is connected to the connecting strip 12. As the lever 13 rotates, the connecting strip 12 also rotates and enters the locking groove 15. The locking groove 15 serves to position and temporarily fix the device. Next, the operator picks up the connecting rope 17, whose connector 18 is equipped with a connecting... The operator aligns the connecting plate 19 with the connecting groove 16 and inserts it into the groove. After inserting the connecting plate 19, the operator holds the lever 13 again and rotates it in the opposite direction, causing the connecting strip 12 to rotate out of the locking groove 15. At the same time, the spring 14 hidden inside the device begins to function. Under the elastic force of the spring 14, the fixing pin 11 springs back into the connecting groove 16 and passes into the connecting plate 19, fixing the connecting rope 17 to one side of the device. Finally, the operator only needs to connect another device to the other end of the connecting rope 17 to successfully complete the connection of the two devices, enabling them to work together in series.

[0038] Working principle: When using the inflatable marine target, first grasp the limiting rod 6 and pull it outwards to disengage the fixing rod 7 from the connecting block 2. Then, loop the top of the counterweight rope 8 onto the fixing rod 7. Afterwards, release the limiting rod 6 to allow the connecting rod 3 to move inwards under the elastic force of the spring 5, causing the fixing rod 7 to re-engage into the connecting block 2 and locking the counterweight rope 8, thus completing the assembly of the equipment. When it is necessary to connect two devices together for series use, first grasp the lever 13 and pull it outwards to disengage the fixing pin 11 from the connecting groove. Slide the connecting rod 16 out, then rotate the lever 13 to make the connecting rod 12 enter the locking groove 15. Then take out the connecting rope 17 and insert the connecting plate 19 at its connector 18 into the connecting groove 16. Then hold the lever 13 again and turn the connecting rod 12 out of the locking groove 15, so that the fixing pin 11 springs back into the connecting groove 16 under the action of the spring 14 and passes into the connecting plate 19 to fix the connecting rope 17 to one side of the equipment. Then connect another piece of equipment to the other end of this connecting rope 17 to complete the connection of the two equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
