Description

Technical Field

[0001] The present invention belongs to the technical field of satellite kinetic energy on-orbit confrontation testing, and specifically refers to an on-orbit confrontation device based on kinetic energy. Background Art

[0002] Satellites are divided into ordinary satellites and small satellites. According to the different masses of satellites, small satellites include microsatellites and nanosatellites. Micro-nano satellites are the collective name for microsatellites and nanosatellites. The space-based kinetic energy on-orbit countermeasure device is an artificial attack-type military satellite. Its working principle is to move the satellite above the target and aim it, then release its kinetic energy column, so that the kinetic energy column moves from space with gravity acceleration to accurately attack the target. At present, there is no device on the market for effective load testing of space-based kinetic energy on-orbit countermeasure devices. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an on-orbit confrontation device based on kinetic energy. According to the space combat restrictions, the biggest constraint on the function of the on-orbit confrontation device of kinetic energy is the input power, so it is necessary to optimize the power distribution as much as possible to maximize the effectiveness of the on-orbit confrontation device of kinetic energy. This scheme relies on centrifugal force to achieve speed superposition while the power input is certain.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides an on-orbit countermeasure device based on kinetic energy, comprising:

[0005] The driving mechanism comprises a motor seat and a driving motor arranged on the motor seat, wherein a first synchronous wheel is rotatably arranged in the motor seat, and the first synchronous wheel is connected to an output shaft of the driving motor;

[0006] The magazine mechanism comprises a magazine, a feeding mechanism and a magazine support, wherein the magazine is arranged on the magazine support, and ammunition is stored in the magazine, and the feeding mechanism is arranged on the magazine support to transport the ammunition;

[0007] A test shell is provided with a main shaft inside, a second synchronous wheel is provided on the main shaft, and a synchronous belt is connected between the second synchronous wheel and the first synchronous wheel; a launch port is provided on the test shell;

[0008] A device for rotating accelerated kinetic energy on-track antagonistic load comprises a rotating arm and a launch control mechanism, wherein the rotating arm is arranged on a main shaft, and a clamping groove is arranged at the front end of the rotating arm for clamping the kinetic energy on-track antagonistic load. In the present scheme, the kinetic energy on-track antagonistic load is set in the form of a bullet, and the launch control mechanism comprises an electromagnet, a control lever and a lever bracket, the middle end of the control lever is hinged on the lever bracket, the control lever is L-shaped, and a bending rod is arranged on it, and a lever block is arranged on the control lever, and the lever block is close to the electromagnet, and the bending rod of the control lever is close to the clamping groove. When the electromagnet is energized, the lever block is attracted, thereby lifting the control lever, releasing the restriction on the clamping groove, and then the kinetic energy on-track antagonistic load can be launched. The purpose of such design is to ensure that there will be no restriction on the right end of the bullet when it is launched to avoid conflict, so the restriction on the right side is designed to be adjustable and displaceable; a counterweight arm is arranged on the rotating arm to maintain dynamic balance during rotation.

[0009] Furthermore, a ratchet groove is provided on the inner ring of the second synchronous wheel, and a ratchet mechanism that is adaptably connected to the ratchet groove is provided on the main shaft. When the motor starts and drives the second synchronous wheel to rotate through synchronous drive, the ratchet mechanism also rotates, thereby driving the main shaft to rotate. When the motor stops and the second synchronous wheel stops, the ratchet mechanism and the main shaft continue to rotate under the action of inertia, and there is no air resistance in the vacuum environment of space, and the inertial force is greater. When the motor starts again, the second synchronous wheel acts on the main shaft with a rotational force again, and the previous inertial force is superimposed, so that the rotational force increases, thereby achieving continuous superposition of speed during intermittent acceleration to achieve optimized power distribution.

[0010] Furthermore, the rotating arm is a cavity, and a connecting rod assembly is arranged in the rotating arm, including a straight rod, a branch rod and a rotating rod. A baffle is fixedly arranged in the rotating arm, and the straight rod can slide linearly through the baffle. A baffle is arranged on the straight rod, and a spring is arranged on the straight rod and between the baffle and the baffle. Two branch rods are arranged and fixedly connected to the end of the straight rod in a forked shape. The rotating rod is hinged on the branch rod. In this scheme, two counterweight arms are arranged, and one end of the two counterweight arms is coaxially hinged inside the rotating arm. A bifurcated rod is provided on the outer side of the counterweight arm, the bifurcated rod is hinged with the rotating rod, a slideway is provided in the rotating arm, a sliding head is provided at the bottom of the branch rod, the sliding head is slidably arranged in the slideway, the front end of the straight rod is an arc-shaped head, which extends into the clamping groove. When the bullet enters the clamping groove, the straight rod is pushed back into the rotating arm, and then the two counterweight arms are pushed to close to each other through the action of the connecting rod assembly. When the bullet is fired, the straight rod rebounds under the elastic force of the spring, and under the linkage action of the connecting rod assembly, the counterweight arms open to each other to achieve dynamic balance after firing;

[0011] Therefore, the maximum stroke of the arc-shaped head under the pushing motion of the straight rod is the diameter in the clamping groove.

[0012] By setting two counterweight arms, connecting the internal connecting rod assembly, the other end of the connecting rod assembly is against the bullet. Assuming that the mass of the bullet is very large, when it is fired at high speed, it will have a huge impact on the main shaft due to the sudden disappearance of the load at the end of the rotating arm. In this scheme, the counterweight arm can automatically complete the opening and closing actions. When rotating, the connecting rod drives the rotating arm to close, and after firing, it drives the rotating arm to open, so as to ensure the realization of dynamic balance, give the device enough time to slow down, and will not cause great impact damage to the main shaft.

[0013] Furthermore, a partition is provided in the magazine to separate the magazine into a spring magazine and an upper magazine. A spring is provided in the spring magazine. The spring magazine is connected to the top of the upper magazine, and the top of the magazine is an arc-shaped transition. The ammunition is stored in the upper magazine and on the top of the spring. The spring pushes the ammunition into the upper magazine. The bottom of the upper magazine is open for the falling of ammunition. The bottom of the upper magazine is connected to a transversely arranged conveying rail, and the feeding mechanism is connected to the conveying rail. The ammunition is pushed by the feeding mechanism to realize automatic loading, and the conveying rail is connected to the clamping groove.

[0014] Furthermore, in order to ensure the smoothness of the automatic rotation control of the rotating arm, the rotating arm is provided with an electric slip ring for adjustment.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: This scheme provides an on-orbit confrontation device based on kinetic energy. In this scheme, a ratchet is set in the driving mechanism and the one-way rotation principle of the ratchet is utilized. When the motor starts, the ratchet mechanism also rotates, thereby driving the main shaft to rotate. When the motor stops, the ratchet mechanism and the main shaft continue to rotate under the action of inertia. Moreover, there is no air resistance in the vacuum environment of space, and the inertial force is greater. When the motor starts again, the second synchronous wheel acts on the main shaft again with a rotational force, which is superimposed on the previous inertial force, thereby increasing the rotational force, thereby achieving the goal of continuously superimposing the speed during intermittent acceleration. The power distribution is optimized; by setting up a rotating accelerated kinetic energy on-orbit counterload device, the counterweight arm can automatically complete the opening and closing actions. During rotation, the connecting rod drives the rotating arm to close, and after launch, the rotating arm is driven to open to ensure the realization of dynamic balance, giving the device enough time to decelerate, and will not cause great impact damage to the main shaft, thereby avoiding a huge impact on the main shaft due to the sudden disappearance of the load at the end of the rotating arm during high-speed rotation and launch. This scheme relies on centrifugal force to achieve speed superposition while maintaining a certain power input, thereby optimizing power distribution to maximize the effectiveness of the kinetic energy on-orbit counterload device.

[0027] The present invention provides an on-orbit countermeasure device based on kinetic energy, comprising:

[0028] The driving mechanism 1 comprises a motor base 2 and a driving motor 3 arranged on the motor base 2, wherein a first synchronous wheel 10 is rotatably arranged in the motor base 2, and the first synchronous wheel 10 is connected to an output shaft of the driving motor 3;

[0029] The magazine mechanism 4 includes a magazine 5, a magazine feeding mechanism 6 and a magazine support 7. The magazine 5 is arranged on the magazine support 7. Ammunition is stored in the magazine 5. The magazine feeding mechanism 6 is arranged on the magazine support 7 to transport the ammunition.

[0030] The test shell 8 has a main shaft 9 inside, a second synchronous wheel 11 is provided on the main shaft 9, and a synchronous belt 12 is connected between the second synchronous wheel 11 and the first synchronous wheel 10; the test shell 8 has a launch port 13;

[0031] The rotating acceleration kinetic energy on-track antagonistic load device 14 comprises a rotating arm 15 and a launch control mechanism 16. The rotating arm 15 is arranged on the main shaft 9. The front end of the rotating arm 15 is provided with a clamping groove 17 for clamping the kinetic energy on-track antagonistic load. In this embodiment, the kinetic energy on-track antagonistic load is in the form of a bullet. The launch control mechanism 16 comprises an electromagnet 18, a control lever 19 and a lever bracket 20. The middle end of the control lever 19 is hinged on the lever bracket 20. The control lever 19 is L-shaped and has a bending rod 21 arranged thereon. There is a lever block 22, which is close to the electromagnet 18, and the bent rod 21 of the control lever 19 is close to the clamping groove 17. When the electromagnet 18 is energized, it attracts the lever block 22, thereby lifting the control lever 19, releasing the restriction on the clamping groove 17, and then the kinetic energy on-track counterload can be launched. The purpose of this design is to ensure that there will be no restriction on the right end of the bullet when it is launched to avoid conflict. Therefore, the restriction on the right side is designed to be adjustable and displaceable; a counterweight arm 23 is set on the rotating arm 15 to maintain dynamic balance during rotation.

[0032] A ratchet groove 24 is provided on the inner ring of the second synchronous wheel 11, and a ratchet mechanism 25 that is adapted and connected to the ratchet groove 24 is provided on the main shaft 9. When the motor starts and drives the second synchronous wheel 11 to rotate through synchronous drive, the ratchet mechanism 25 also rotates, thereby driving the main shaft 9 to rotate. When the motor stops and the second synchronous wheel 11 stops, the ratchet mechanism 25 and the main shaft 9 continue to rotate under the action of inertia, and there is no air resistance in the vacuum environment of space, and the inertial force is greater. When the motor starts again, the second synchronous wheel 11 acts on the main shaft 9 again with a rotational force, and the previous inertial force is superimposed, so that the rotational force is increased, thereby achieving continuous superposition of speed during intermittent acceleration to achieve optimized power distribution.

[0033] The rotating arm 15 is a cavity, and a connecting rod assembly 26 is provided in the rotating arm 15, including a straight rod 27, a branch rod 28 and a rotating rod 29. A baffle 30 is fixedly provided in the rotating arm 15, and the straight rod 27 can slide linearly through the baffle 30. A baffle 31 is provided on the straight rod 27, and a spring is provided on the straight rod 27 and between the baffle 31 and the baffle 30. Two branch rods 28 are provided and fixedly connected to the end of the straight rod 27 in a forked shape. The rotating rod 29 is hinged on the branch rod 28. In this scheme, two counterweight arms 23 are provided, and one end of the two is coaxially hinged to the inside of the rotating arm 15. A bifurcated rod 32 is provided on the outer side of the weight arm 23, and the bifurcated rod 32 is hinged to the rotating rod 29. A slideway 33 is provided in the rotating arm 15, and a sliding head 34 is provided at the bottom of the branch rod 28. The sliding head 34 is slidably arranged in the slideway 33. The front end of the straight rod 27 is an arc-shaped head, which extends into the clamping groove 17. When the bullet enters the clamping groove 17, the straight rod 27 is pushed back into the rotating arm 15, and then the two counterweight arms 23 are pushed to close to each other through the action of the connecting rod assembly 26. When the bullet is fired, the straight rod 27 rebounds under the elastic force of the spring, and under the linkage action of the connecting rod assembly 26, the counterweight arms 23 open to each other to achieve dynamic balance after firing;

[0034] Therefore, the maximum stroke of the arc-shaped head under the pushing motion of the straight rod 27 is the diameter of the clamping groove 17.

[0035] By setting two counterweight arms 23, connecting the internal connecting rod assembly 26, the other end of the connecting rod assembly 26 is against the bullet. Assuming that the mass of the bullet is very large, when it is fired at high speed, it will have a huge impact on the main shaft 9 due to the sudden disappearance of the load at the end of the rotating arm 15. In this solution, the counterweight arm 23 can automatically complete the two actions of opening and closing. When rotating, the connecting rod drives the rotating arm 15 to close, and after firing, it drives the rotating arm 15 to open, so as to ensure the realization of dynamic balance, give the device enough time to slow down, and will not cause great impact damage to the main shaft 9.

[0036] A partition 35 is provided in the magazine 5 to separate the magazine 5 into a spring magazine 36 and an upper magazine 37. A spring is provided in the spring magazine 36. The spring magazine 36 is connected to the top of the upper magazine 37, and the top of the magazine 5 is an arc-shaped transition. The ammunition is stored in the upper magazine 37 and on the top of the spring. The spring pushes the ammunition into the upper magazine 37. The bottom of the upper magazine 37 is open for the ammunition to fall. The bottom of the upper magazine 37 is connected to a transversely arranged conveying rail 38. The feeding mechanism 6 is connected to the conveying rail 38. The ammunition is pushed by the feeding mechanism 6 to realize automatic loading. In this embodiment, the feeding mechanism 6 can be a pushing cylinder, and the conveying rail is connected to the clamping groove.

[0037] In order to ensure the smoothness of the automatic rotation of the rotating arm 15 , the rotating arm 15 is provided with an electric slip ring 39 for adjustment.

[0038] In the embodiment, the model of the synchronous belt 12 is 8M, the first synchronous wheel 10 has 42 teeth, and the second synchronous wheel 11 has 24 teeth; the motor base 2 is provided with an adjustable margin to better adapt to the imperfect meshing of the synchronous wheels caused by processing errors.

[0039] In the embodiment, four bearings are arranged on the main shaft 9, and the models are 61905, 61905, 60 / 22, and 61904 respectively.

[0040] When in use, the ammunition is stored in the upper magazine 37 and on the top of the spring. The spring pushes the ammunition into the upper magazine 37 and drops it from the bottom opening. The feeding mechanism 6 pushes the ammunition into the clamping groove 17. When the bullet enters the clamping groove 17, the straight rod 27 is pushed back into the rotating arm 15, and then the two counterweight arms 23 are pushed to close to each other through the action of the connecting rod assembly 26. When the bullet is fired, the straight rod 27 rebounds under the elastic force of the spring, and the counterweight arms 23 are opened to each other under the linkage action of the connecting rod assembly 26, so as to achieve dynamic balance after firing.

[0041] When the bullet is fired, when the motor starts and the second synchronous wheel 11 is driven to rotate through synchronous drive, the ratchet mechanism 25 also rotates, thereby driving the main shaft 9 to rotate. When the motor stops and the second synchronous wheel 11 stops, the ratchet mechanism 25 and the main shaft 9 continue to rotate under the action of inertia, and there is no air resistance in the vacuum environment of space, and the inertial force is greater. When the motor is restarted, the second synchronous wheel 11 again acts on the main shaft 9 with a rotational force, which is superimposed on the previous inertial force, thereby increasing the rotational force, thereby achieving continuous superposition of speed during intermittent acceleration to achieve optimized power distribution.
