Description

Technical Field

[0001] The utility model relates to the technical field of radar job training, in particular to the technical field of corner reflector throwing, and specifically is a corner reflector throwing device based on an unmanned aerial vehicle. Background Art

[0002] At present, the training method for radar personnel is mainly to conduct tracking and capture training through simulator-simulated tracks. The training tracks are single and simple, which is quite different from actual combat tasks and the training effect is not good. At the same time, it is also impossible to test the multi-target tracking performance of radar equipment in actual combat. Summary of the invention

[0003] In order to solve the problem that there is a large gap between the current tracking and capturing training of radar personnel through simulators and actual combat tasks, and that it is impossible to detect the multi-target tracking performance of radar equipment in actual combat, the utility model provides a new corner reflector throwing device based on a drone.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A corner reflector throwing device based on a drone, comprising a plurality of hexagonal corner reflectors (the hexagonal corner reflectors are existing structures), a throwing box, and a remote controller;

[0006] Each hexagonal corner reflector includes a middle plate and two vertical plates, the two vertical plates are cross-arranged to form a vertical cross plate, the middle plate is horizontally inserted and fixed in the middle of the vertical cross plate, and a locking ring is fixed on the top surface (the description terms such as the top surface and the bottom surface in this application are all relative to the position of the throwing device when throwing) of one end portion in the left and right directions of the middle plate;

[0007] The throwing box includes a square vertical cylinder, a cover plate is fixed on the top of the three-dimensional cylinder, and multiple partitions are fixed in the vertical cylinder to divide the space in the cylinder into square compartments for placing multiple hexagonal corner reflectors. An electric lock is fixed on the inner side of a side plate of each compartment close to the compartment adjacent to the left and right directions of the compartment. The electric lock is controlled to open or close by a remote control. The electric lock is adapted to the locking ring on the corresponding hexagonal corner reflector. The bottom end of the other side plate of each compartment away from the compartment adjacent to the left and right directions of the compartment is fixed with a limit block by a hinge, and the rotating shaft of the hinge is arranged along the front-to-back direction. One end face of each limit block close to the compartment is provided with a limit groove adapted to the other side end of the middle plate of the hexagonal corner reflector in the left and right directions.

[0008] When in use, the other end of the left and right directions of the middle plate of the hexagonal corner reflector is inserted into the limiting groove, and one end is fixed to the electric lock through a locking ring, so that the hexagonal corner reflector is fixed in the corresponding compartment, and at the same time, the cover plate of the throwing device is fixed (it is well known to those skilled in the art that the cover plate and the drone can be fixed by welding or connecting ears or bolts) under the drone. When throwing, the remote control controls the electric lock to open, and one end of the hexagonal corner reflector loses its fixation. Since the other end of the hexagonal corner reflector is only stuck in the limiting groove, and the limiting groove is fixed to the bottom end of the left or right plate of the compartment away from the adjacent compartment through a hinge, the hexagonal corner reflector will break away from the limiting groove due to gravity, thereby breaking away from the throwing box and falling, thereby realizing the throwing of the hexagonal corner reflector.

[0009] Furthermore, a drop cylinder arranged in the vertical direction is fixed to the inner side of the front side plate or the inner side of the rear side plate of each compartment, and the drop cylinder is located above the middle plate of the corner reflector. A parachute is placed in the drop cylinder, and the parachute is connected to the hexagonal corner reflector through a rope. When in use, as the hexagonal corner reflector is thrown, the parachute also falls and opens, and the falling speed of the hexagonal corner reflector is reduced by the parachute, so as to prevent the hexagonal corner reflector from falling too fast and injuring people or objects around it, and at the same time, it is convenient for the radar to better capture the signal of the hexagonal corner reflector, so as to obtain more data.

[0010] Furthermore, a connecting ear is fixed on the top surface of the cover plate for fixing to the drone via bolts, so as to facilitate the installation and disassembly of the throwing device.

[0011] Furthermore, the vertical cylinder, cover plate and partition are all made of KT plates. L-shaped vertical reinforcement plates are fixed on the four sides of the vertical cylinder. The short plate of the L-shaped vertical reinforcement plate is fixedly connected to the cover plate. The bottom end of the long plate of the L-shaped vertical reinforcement plate extends outward and then upward to form a slot that matches the side plate of the vertical cylinder. The slot is matched with the side plate of the vertical cylinder and then connected by bolts. The limit block is fixed to the outer bottom surface of the slot, which not only reduces the weight of the throwing box and facilitates the drone to be carried, but also ensures the overall stability of the throwing device.

[0012] Furthermore, tin foil is pasted on the outer sides of the four side plates of the vertical cylinder, thereby improving the signal-to-noise ratio of the hexagonal corner reflector.

[0013] Furthermore, there are four hexagonal corner reflectors, and the plurality of partitions are generally in a cross shape, thereby dividing the vertical cylinder into four square compartments, and the structure is specific and standardized.

[0014] The beneficial effects produced by the utility model are as follows: the throwing device described in the utility model realizes tracking and capturing training in actual combat mission mode, the simulated trajectory is unstable due to the influence of objective environment, the training operation is no longer single, which is convenient for better training of radar personnel, and also convenient for multi-target tracking performance detection of radar equipment in actual combat.

[0024] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , 2 As shown in 3, a corner reflector throwing device based on a drone includes a plurality of hexagonal corner reflectors 1 (the hexagonal corner reflectors 1 are existing structures), a throwing box, and a remote controller;

[0026] Each hexagonal corner reflector 1 comprises a middle plate 12 and two vertical plates 11, the two vertical plates 11 are cross-arranged to form a vertical cross plate, the middle plate 12 is horizontally inserted and fixed in the middle of the vertical cross plate, and a locking ring is fixed to the top surface (the description terms such as the top surface and the bottom surface in this application are all relative to the position of the throwing device when throwing) of one end portion in the left and right directions of the middle plate 12;

[0027] The throwing box includes a square vertical cylinder 2, a cover plate 3 is fixed on the top of the three-dimensional cylinder, and multiple partitions 4 are fixed in the vertical cylinder 2 to divide the space in the cylinder into square compartments for placing multiple hexagonal corner reflectors 1 respectively. An electric lock 5 is fixed on the inner side of a side plate of each compartment close to the compartment adjacent to the left and right directions of the compartment. The electric lock 5 is controlled to open or close by a remote control. The electric lock 5 is adapted to the locking ring on the corresponding hexagonal corner reflector 1. The bottom end of the other side plate of each compartment away from the compartment adjacent to the left and right directions of the compartment is fixed with a limiting block 6 by a hinge 8, and the rotating shaft of the hinge 8 is arranged along the front-to-back direction. Each limiting block 6 is provided with a limiting groove 7 adapted to the other side end of the middle plate 12 of the hexagonal corner reflector 1 in the left and right directions on one end face close to the compartment where it is located.

[0028] When in use, the other side end of the middle plate 12 of the hexagonal corner reflector 1 in the left and right directions is inserted into the limiting groove 7, and the one side end is fixed to the electric lock 5 through a locking ring, so that the hexagonal corner reflector is fixed in the corresponding compartment, and at the same time, the cover plate 3 of the throwing device is fixed (it is well known to those skilled in the art that the cover plate 3 and the drone can be fixed by welding or connecting ears 10 or bolts) under the drone. When throwing, the remote control controls the electric lock 5 to open, and one side end of the hexagonal corner reflector 1 loses its fixation. Since the other side end of the hexagonal corner reflector 1 is only stuck in the limiting groove 7, and the limiting groove 7 is fixed to the bottom end of the left or right plate of the compartment away from the adjacent compartment through the hinge 8, due to gravity, the hexagonal corner reflector 1 will break away from the limiting groove 7, thereby breaking away from the throwing box and falling, thereby realizing the throwing of the hexagonal corner reflector 1.

[0029] In specific implementation, a drop cylinder 9 (in specific implementation, the drop cylinder 9 is a cylinder) whose axial direction is arranged in the vertical direction is fixed on the inner side surface of the front side plate or the inner side surface of the rear side plate of each compartment. The drop cylinder 9 is located above the middle plate 12 of the corner reflector. A parachute is placed in the drop cylinder 9, and the parachute is connected to the hexagonal corner reflector 1 through a rope. When in use, as the hexagonal corner reflector 1 is thrown, the parachute also falls and opens, and the falling speed of the hexagonal corner reflector 1 is reduced by the parachute, so as to prevent the hexagonal corner reflector 1 from falling too fast and injuring people or objects around, and at the same time, it is convenient for the radar to better capture the signal of the hexagonal corner reflector 1, so as to obtain more data.

[0030] In specific implementation, a connecting ear 10 for fixing to the drone via bolts is fixed on the top surface of the cover plate 3, so as to facilitate the installation and disassembly of the throwing device.

[0031] During specific implementation, the vertical cylinder 2, the cover plate 3, and the partition plate 4 are all made of KT plates. L-shaped vertical reinforcement plates are fixed on the four sides of the vertical cylinder 2. The short plate of the L-shaped vertical reinforcement plate is fixedly connected to the cover plate 3. The bottom end of the long plate of the L-shaped vertical reinforcement plate extends outward and then upward to form a slot that matches the side plate of the vertical cylinder 2. The slot is matched with the side plate of the vertical cylinder 2 and then connected by bolts. The limit block 6 is fixed to the outer bottom surface of the slot, which not only reduces the weight of the throwing box and facilitates the drone to be carried, but also ensures the overall stability of the throwing device.

[0032] In a specific implementation, tin foil is pasted on the outer side surfaces of the four side plates of the vertical cylinder 2, thereby improving the signal-to-noise ratio of the hexagonal corner reflector 1.

[0033] In a specific implementation, there are four hexagonal corner reflectors 1, and a plurality of partitions 4 are cross-shaped as a whole, thereby dividing the vertical cylinder 2 into four square compartments, and the structure is specific and standardized.

[0034] During specific implementation, the automatic casting of the four corner reflectors can be achieved by adding components such as a time delay relay, a circuit board, and a power supply battery.

[0035] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
