Description

Technical Field

[0001] This application relates to the field of military training equipment technology, and in particular to a mobile target for maritime combat training. Background Technology

[0002] Maritime shooting training is an important part of routine training for naval vessels. Due to the significant differences between the maritime and land environments, maritime shooting training has its own unique requirements.

[0003] The maritime environment typically involves large waves, causing targets and ships to sway significantly. Smaller targets may even be pushed from their original positions by the wind or waves, increasing the difficulty of maritime shooting training. To mitigate the impact of sea winds, maritime targets are designed with special structures. For example, CN219284120U and CN115900448A are designed with a conical structure, ensuring that the target has a large area facing the radar while minimizing its windward area, thus reducing the impact of sea winds on the target.

[0004] However, although the target in the aforementioned patent uses a conical structure which can reduce the windward area to some extent and thus reduce the impact of sea wind, its windward area is still relatively large, and it will still have a significant impact when the sea wind is strong. Summary of the Invention

[0005] This application provides a mobile target for maritime combat training to solve the problem that the target body of the existing target is greatly affected by sea wind.

[0006] On one hand, embodiments of this application provide a moving target for maritime combat training, including:

[0007] Base plate;

[0008] A raft, placed at the bottom of the base plate, is used to provide buoyancy to the base plate;

[0009] The target body is set on the top surface of the base plate. A drive mechanism is set on the top of the target body, and a detection unit is also set on the base plate. The detection unit is used to detect the real-time wind direction. The target body includes a frame and a target plate. The frame is a conical structure composed of multiple mounting rods. Each mounting rod is located at the corner of the conical structure. The drive mechanism includes a drive unit and a drive rod. The drive rod is rotatably mounted on the mounting rod. The target plate is fixedly mounted on the drive rod one by one. The drive unit drives the drive rod to rotate according to the real-time wind direction, so that the target plate rotates to a direction parallel to the real-time wind direction.

[0010] The mobile target for maritime combat training described in this application has the following advantages:

[0011] The target plate adopts a rotatable structure. When there is sea wind, the target plate is rotated to an angle parallel to the real-time wind direction to minimize the windward area and thus reduce the impact of sea wind on the stability of the target. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Figure 1-5This is a schematic diagram of the structure of a moving target for maritime combat training provided in an embodiment of this application. This embodiment of the application provides a moving target for maritime combat training, comprising:

[0021] Base plate 100;

[0022] A raft 110 is disposed at the bottom of the base plate 100 and is used to provide buoyancy to the base plate 100.

[0023] The target body 200 is set on the top surface of the base plate 100. A drive mechanism 210 is set on the top of the target body 200. At the same time, a detection unit 220 is also set on the base plate 100. The detection unit 220 is used to detect the real-time wind direction. The target body 200 includes a frame and a target plate 201. The frame is a conical structure composed of multiple mounting rods. Each mounting rod is located at the corner of the conical structure. The drive mechanism 210 includes a drive unit 211 and a drive rod 213. The drive rod 213 is rotatably mounted on the mounting rod. The target plates 201 are fixedly mounted on the drive rods 213 one by one. The drive unit 211 drives the drive rod 213 to rotate according to the real-time wind direction, so that the target plates 201 rotate to a direction parallel to the real-time wind direction.

[0024] For example, the raft 110 can be made of lightweight materials or have a hollow structure, and there can be one or more of them. Regardless of the structure and number, it is necessary to ensure the stability of the moving target itself so that it will not easily capsize in the wind and waves.

[0025] To facilitate rapid and accurate detection of real-time wind direction, the detection unit 220 can be located at the upper end of the drive mechanism 210. Since there are no obstructions at this location, the air can flow quickly and undisturbed, thereby making the detection results of the detection unit 220 accurate and reliable.

[0026] In this embodiment, the frame is a pyramid or frustum structure, meaning each side is a plane, and the target plate 201 is rotatably mounted on each side, thus the target plate 201 is also a flat plate. Multiple retaining rings can be rotatably fitted onto the outer surface of the drive rod 213. Each retaining ring has the same thickness, and its outer surface is fixedly mounted on the mounting rod, keeping the drive rod 213 and the mounting rod parallel.

[0027] In one possible embodiment, the drive mechanism 210 further includes a drive wheel 212 and a driven wheel 214. The drive wheel 212 is coaxially connected to the drive shaft of the drive unit 211, and the driven wheel 214 is disposed at the upper end of the drive rod 213. The driven wheel 214 and the drive wheel 212 are connected in a transmission manner.

[0028] For example, the drive unit 211 can be a stepper motor, and the drive wheel 212 and the driven wheel 214 can be smooth wheels or gears. When smooth wheels are used, the transmission connection can be achieved through friction or belts, while when gears are used, the transmission connection can be achieved through meshing.

[0029] Furthermore, the number of drive units 211 in the drive mechanism 210 can be one or more. When one drive unit 211 is used, multiple driven wheels 214 rotate under the drive of the same drive wheel 212. When multiple drive units 211 are used, the number of drive units 211 should be the same as the number of driven wheels 214, that is, each drive unit 211 is used to drive one driven wheel 214 to rotate.

[0030] In one possible embodiment, the drive wheel 212 is an inverted cone, or the driven wheel 214 is a regular cone, and the axial directions of the multiple drive rods 213 have a certain included angle so that each drive rod 213 is parallel to the corresponding mounting rod.

[0031] For example, regardless of whether there is one or more drive units 211, the drive units 211 need to be installed vertically to save space. Since the drive rod 213 is inclined, at least one of the drive wheel 212 or driven wheel 214 needs to be set as a cone so that the drive wheel 212 can cooperate with the inclined driven wheel 214 when installed vertically.

[0032] In one possible embodiment, the target plate 201 is divided into multiple groups, each group including two parallel target plates 201. When the detection unit 220 detects the real-time wind direction, the drive unit 211 controls the target plate 201 at the forefront of the real-time wind direction and the other target plate 201 in the same group to rotate in the same direction by the same angle, so that the target plates 201 in the group rotate simultaneously to the same direction as the real-time wind direction.

[0033] For example, the parallel target plates 201 can also be referred to as facing target plates 201. When the angle between the sea breeze and one of the two facing target plates 201 is large, and the angle between them is greater than the angle between the sea breeze and the two adjacent target plates 201, the current target plate 201 is the target plate 201 that is at the forefront in the real-time wind direction. At this time, the drive unit 211 can be energized and rotated, driving the two target plates 201 in the group to rotate synchronously.

[0034] Specifically, a control unit can be set on the base plate 100. The control unit can be a microprocessor, which stores the relative position data of the detection unit 220 and the target 200. When the detection unit 220 detects the real-time wind direction, the control unit can calculate the angle between each target plate 201 and the real-time wind direction based on the position relationship data and the real-time wind direction. After comparing the angles, the target plate 201 that needs to be controlled can be determined.

[0035] In one possible embodiment, the drive rod 213 is rotatably connected to the driven wheel 214. A locking component 215 is provided on the side of the drive rod 213 near the driven wheel 214. The locking component 215 locks or unlocks the drive rod 213 and the driven wheel 214 under different energized states, so that the drive rod 213 rotates together with the driven wheel 214 or rotates independently, so that a specific set of target plates 201 rotates with the drive unit 211, while the other target plates 201 remain fixed.

[0036] For example, if each drive rod 213 is controlled by a drive unit 211, the control unit can drive the drive unit 211 corresponding to the target plate 201 to be controlled to work.

[0037] When multiple drive rods 213 are controlled by the same drive unit 211, the driven wheel 214 on each drive rod 213 will rotate under the drive of the drive wheel 212. Therefore, the locking component 215 is needed to control the linkage state between the driven wheel 214 and the drive rod 213. When the two need to rotate synchronously, the locking component 215 is energized to lock. When the locking component 215 is de-energized, the driven wheel 214 and the drive rod 213 will remain independent, that is, the driven wheel 214 will not drive the drive rod 213 to rotate.

[0038] Specifically, a convex ring 2143 is provided on the upper side of the drive rod 213, and a groove matching the convex ring 2143 is also provided on the inner side of the driven wheel 214. When the convex ring 2143 is engaged in the groove, the drive rod 213 can rotate freely inside the driven wheel 214. Furthermore, to reduce friction, a ball bearing can be provided between the convex ring 2143 and the groove.

[0039] In one possible embodiment, the locking assembly 215 includes an electromagnetic unit 2150. A mounting cavity is provided on the bottom surface of the driven wheel 214. The upper end of the drive rod 213 is rotatably connected to the lower end of the mounting cavity. An insert rod 2141 is connected to the inner top surface of the mounting cavity via an elastic element 2142. The insert rod 2141 is made of ferromagnetic material. A slot is provided on the top surface of the drive rod 213. An outer stop block 2144 is provided axially on the outer side of the insert rod 2141. An upper stop block 2145 and a lower stop block 2146 are respectively provided on the inner side of the mounting cavity and the inner side of the slot. When the electromagnetic unit 2150 is energized, it generates magnetic force, causing the insert rod 2141 to move downward and stretch the elastic element 2142. The outer stop block 2144 contacts the upper stop block 2145 and the lower stop block 2146, thereby connecting the driven wheel 214 and the drive rod 213 together.

[0040] For example, the insertion rod 2141 can be made of iron or its alloy, or a ferromagnetic metal block can be provided at the bottom of the insertion rod 2141, while the elastic element 2142 is preferably a helical spring, which suspends the insertion rod 2141 on the inner top surface of the mounting cavity. When the electromagnetic unit 2150 is energized and pulls the insertion rod 2141 downward, the elastic element 2142 will be stretched, and at this time the elastic element 2142 will generate elastic potential energy. When the electromagnetic unit 2150 is de-energized and the magnetism disappears, the insertion rod 2141 moves rapidly upward under the action of the elastic potential energy of the elastic element 2142, thereby causing the outer stop block 2144, the upper stop block 2145, and the lower stop block 2146 to disengage, thereby releasing the linkage between the driven wheel 214 and the drive rod 213.

[0041] Furthermore, in addition to synchronously controlling the rotation of two opposing targets 201, asynchronous rotation control can also be applied to all targets 201. Specifically, since each target 201 has a different orientation, its rotation angle is also different. These target 201 can start rotating simultaneously and stop rotating at different times, or they can start rotating at different times and stop rotating at the same time. The control unit can determine the rotation angle of each target 201 based on its orientation and the real-time wind direction, and then use either of the two rotation control strategies mentioned above to ensure that each target 201 is in a direction parallel to the real-time wind direction after the control is completed, thereby minimizing the windward area.

[0042] In one embodiment, each outer stop 2144 is divided into two sub-stops along the axial direction of the insert rod 2141. The distance between the two sub-stops is approximately the same as the distance between the upper stop 2145 and the lower stop 2146. After the insert rod 2141 moves downward, the two sub-stops contact the upper stop 2145 and the lower stop 2146, respectively. With this structure, the insert rod 2141 can be pre-inserted into the slot, as long as it is ensured that the lower stop 2146 and the outer stop 2144 do not contact each other.

[0043] In another embodiment, each outer stop 2144 is an integral part extending axially along the insertion rod 2141. Multiple upper stop blocks 2145 are distributed circumferentially on the inner side of the mounting cavity, with upper stop grooves between adjacent upper stop blocks 2145. The outer stop blocks 2144 are slidably inserted into the upper stop grooves. Multiple lower stop blocks 2146 are distributed circumferentially on the inner side of the slot, with lower stop grooves between adjacent lower stop blocks 2146. The upper and lower stop grooves have roughly the same width and are positioned in a one-to-one correspondence. When the upper stop groove rotates with the driven wheel 214 to communicate with the lower stop groove, the insertion rod 2141 moves downward and inserts into the lower stop groove. With this structure, when the driven wheel 214 and the drive rod 213 are not linked, it is necessary to ensure that no part of the insertion rod 2141 is in the slot to ensure that the linkage state between the driven wheel 214 and the drive rod 213 is controlled.

[0044] Regardless of which structure is adopted in the two embodiments above, the upper stop 2145 and the lower stop 2146 need to be densely distributed in the mounting cavity and slot respectively, so that the driven wheel 214 only needs to rotate a very small angle to connect the upper stop slot and the lower stop slot, thereby allowing the outer stop 2144 to be quickly inserted, reducing the idle angle and improving the control sensitivity.

[0045] In one possible embodiment, the electromagnetic unit 2150 is a ring structure, and the electromagnetic unit 2150 is rotatably sleeved on the drive rod 213 via the rotating unit 2151.

[0046] For example, the rotating unit 2151 can be a ball bearing, which rotatably mounts the electromagnetic unit 2150 on the drive rod 213. The outer surface of the electromagnetic unit 2150 can be fixed on the mounting rod so that the electromagnetic unit 2150 can be fixed and facilitates power supply to the electromagnetic unit 2150.

[0047] In one possible embodiment, the edge of the target plate 201 and the mounting rod are provided with mutually attractive magnetic units so that the target plate 201 is attracted to the mounting rod when rotated to the closed state.

[0048] For example, the magnetic unit can be strip-shaped or disc-shaped, and it is disposed at corresponding positions on the edge of the target plate 201 and the mounting rod.

[0049] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0050] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
