DETAILED DESCRIPTION
[0047] The embodiment of the present invention provides a protection performance test device for an electromagnetic pulse protection filter, which is used to solve the technical problem that the prior art cannot perform a simulation test on the protection performance of an electromagnetic pulse filter under extreme collision.
[0048] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiment described below is only an embodiment of a component of the present invention, rather than an embodiment of all components. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0049] See also Figures 1 to 7 The present invention provides a protection performance test device for an electromagnetic pulse protection filter, comprising:
[0050] Anti-collision test box 1;
[0051] The rotating mechanism 2 includes a driving component 20 and a rotating component 21, the driving component 20 is in transmission connection with the rotating component 21, and at least a part of the rotating component 21 is disposed in the anti-collision test box 1;
[0052] A throwing mechanism 3, the throwing mechanism 3 is connected to the built-in end of the rotating component 21, and the throwing mechanism 3 includes a connecting component 30 and a clamping component 31; the clamping component 31 is connected to the connecting component 30, and the clamping component 31 is used to clamp the filter to be tested;
[0053] The rotation of the rotating mechanism 2 is used to centrifugally separate the filter to be tested from the clamping component 31 , so that the filter to be tested collides with the anti-collision test box 1 .
[0054] During the working process of this embodiment, the filter to be tested is clamped and fixed in the clamping component 31, and the driving component 20 is started to rotate the rotating component 21 and the throwing mechanism 3 in the anti-collision test box 1. When the rotating component 21 is continuously accelerated, the centripetal force required for the filter to be tested to maintain circular motion is continuously increased. When the maximum preset combined external force (the friction force of the clamping component 31 on it) received by the filter to be tested is less than the centripetal force required by the filter to be tested, the filter to be tested will separate from the clamping component 31 and make a centrifugal motion to collide with the anti-collision test box 1. After the filter to be tested collides with the anti-collision test box 1, the collision condition of the filter to be tested is checked to judge the protection performance of the filter to be tested.
[0055] It can be seen from the above working process that the rotating component 21 will drive the filter to be tested on the clamping component 31 to continuously perform circular motion. As the speed of the filter to be tested increases, the force exerted on the filter to be tested gradually reaches the maximum threshold of the preset combined external force. When the required centripetal force exceeds this maximum threshold, the filter to be tested will separate from the clamping component 31 and perform centrifugal motion. At this time, the speed of the filter to be tested is quite fast, and the situation in which it collides with the anti-collision test box 1 is equivalent to the situation in which the filter to be tested collides at an extremely high speed. Therefore, this embodiment can simulate the situation in which the electromagnetic pulse filter faces an extreme collision, thereby being able to test the protection performance of the electromagnetic pulse filter in this situation.
[0056] Compared with the prior art, the advantage of this embodiment is that the filter to be tested stores energy by rotating the rotating component 21, so that the filter to be tested reserves enough kinetic energy. When the filter performs centrifugal motion, it can collide with the anti-collision test box 1 at an extremely high speed, thereby simulating the extreme collision situation faced by the electromagnetic pulse filter, and the filter protection performance test range is wide; avoiding the problems of the prior art of simply dropping the electromagnetic pulse filter from a high place for protection test, or simply hammering the filter for protection test, which makes the electromagnetic pulse filter face small impact force, small range of protection performance test, and inability to simulate tests on the electromagnetic pulse filter under extreme conditions.
[0057] As a possible example, Figure 1 , Figure 4 and Figure 5 As shown, the present embodiment provides a structure that can be realized by the clamping component 31, the clamping component 31 includes a first clamping portion 310 and a second clamping portion 311, the clamping space of the first clamping portion 310 and the second clamping portion 311 forms a circular track when rotating, and the circular track is in the anti-collision test box 1; the first clamping portion 310 is connected to the connecting component 30, and the second clamping portion 311 is connected to the connecting component 30, and the distance between the first clamping portion 310 and the second clamping portion 311 is adjustable to adjust the force of the first clamping portion 310 and the second clamping portion 311 clamping the filter to be tested, and can adjust the friction between the first clamping portion 310, the second clamping portion 311 and the filter to be tested, thereby changing the preset combined external force received by the filter to be tested during rotation, and adjusting the speed at which the filter to be tested is thrown out; and the distance between the first clamping portion 310 and the second clamping portion 311 is adjustable, and electromagnetic pulse protection filters of different sizes can be clamped and fixed according to needs, and the adaptability is wide.
[0058] Based on the above embodiments, in a specific application scenario, the tester needs to test the protective performance of the filter to be tested with a smaller impact force, then the first clamping portion 310 and the second clamping portion 311 clamp the filter to be tested with a smaller force, so that the filter to be tested and the clamping component 31 are thrown out at a smaller speed during centrifugal separation, and the filter to be tested hits the anti-collision test box 1 with a smaller kinetic energy; on the contrary, if the tester needs to test the protective performance of the filter to be tested with a larger impact force, then the first clamping portion 310 and the second clamping portion 311 clamp the filter to be tested with a larger force, so that the filter to be tested hits the anti-collision test box 1 with a larger kinetic energy.
[0059] In some specific embodiments, Figure 4 As shown, a structure that can be realized by the first clamping part 310 is further provided, and the first clamping part 310 includes an adjusting member 3100 and an adjusting clamping plate 3101; the adjusting member 3100 is connected to the connecting member 30, and the adjusting member 3100 and the adjusting clamping plate 3101 are detachably connected. When the preset connection force between the adjusting clamping plate 3101 and the adjusting member 3100 is less than the centripetal force exerted on the adjusting clamping plate 3101, the adjusting clamping plate 3101 and the adjusting member 3100 are separated, that is, the structure of the first clamping part 310 itself will be centrifugally separated. After the structure of the first clamping part 310 itself is centrifugally separated, the clamped filter to be tested Due to the loss of external force, the filter will naturally perform centrifugal separation movement. During the centrifugal movement of the filter to be tested, due to the separation of the adjusting splint 3101, the filter to be tested will collide with the adjusting splint 3101 during the separation process, thereby changing the centrifugal movement trajectory of the filter to be tested, making the filter to be tested perform relatively irregular centrifugal movement, and the impact test flexibility of the filter to be tested is higher; and the separated adjusting splint 3101 is equivalent to a flying foreign body in an extreme high-speed collision situation. The addition of the adjusting splint 3101 to the centrifugal movement of the filter to be tested can improve the simulation of the extreme high-speed collision.
[0060] Based on the above embodiments, in a specific application scenario, the tester can flexibly set the preset connection force between the adjustment clamp 3101 and the adjustment member 3100, as well as the clamping force of the first clamping portion 310 and the second clamping portion 311. The test may be that the preset connection force between the adjustment clamp 3101 and the adjustment member 3100 is smaller than the centripetal force required for the adjustment clamp 3101, the adjustment clamp 3101 is separated, the resultant external force of the filter to be tested disappears, and the filter to be tested is centrifugally collided with the anti-collision test box 1; or the preset resultant external force applied by the first clamping portion 310 and the second clamping portion 311 to the filter to be tested is smaller than the centripetal force required for the filter to be tested, the filter to be tested is separated from the first clamping portion 310 and the second clamping portion 311, and collided with the anti-collision test box 1.
[0061] Exemplarily, the tester can set the adjustment clamp 3101 and the adjustment member 3100 not to separate during the rotation process. The centrifugal separation of the filter to be tested is that the preset combined external force applied by the first clamping part 310 and the second clamping part 311 to the filter to be tested is smaller than the centripetal force required by the filter to be tested, causing it to separate. When the filter to be tested is centrifugally separated, the filter to be tested performs centrifugal motion along the clamping gap direction of the first clamping part 310 and the second clamping part 311, and the filter to be tested collides with the anti-collision test box 1 with a relatively regular trajectory to test the protection performance of the filter to be tested.
[0062] Exemplarily, the tester can set the adjustment clamp 3101 and the adjustment member 3100 to separate during the rotation process. The centrifugal separation of the filter to be tested is caused by the separation of the adjustment clamp 3101 and the disappearance of the external force of the filter to be tested. When the filter to be tested is centrifuged, the filter to be tested and the adjustment clamp 3101 perform centrifugal motion together. The adjustment clamp 3101 will interfere with the motion trajectory of the filter to be tested, causing the filter to be tested to collide with the anti-collision test box 1 with a relatively irregular trajectory, so as to test the protection performance of the filter to be tested.
[0063] In this embodiment, if Figure 5 and Figure 7 As shown, a connection structure that can be realized between the adjusting member 3100 and the adjusting splint 3101 is further provided, wherein the adjusting member 3100 includes an adjusting body 31000, an adjusting screw 31001 and an adjusting spring 31002; the adjusting body 31000 is provided with an adjusting slot and an adjusting through hole, and the adjusting through hole is connected to the adjusting slot; one end of the adjusting splint 3101 is provided in the adjusting slot, and the other end of the adjusting splint 3101 is provided outside the adjusting slot, and the vertical projection surface of the adjusting through hole is located on the adjusting splint 3101, and the adjusting screw 31001 is screwed into the adjusting through hole, and the adjusting An adjusting spring 31002 is compressed between the screw 31001 and the adjusting splint 3101, and the adjusting spring 31002 elastically abuts against the adjusting splint 3101. The adjusting splint 3101 is pressed into the adjusting slot by the compression force of the spring. When the adjusting splint 3101 makes a circular motion, the adjusting spring 31002 and the adjusting splint 3101 form a centripetal friction force to limit the displacement of the adjusting splint 3101. When the preset connection force between the adjusting splint 3101 and the adjusting spring 31002 is insufficient to provide the required centripetal force, the adjusting splint 3101 will be centrifugally separated.
[0064] When it is necessary to replace a different adjusting splint 3101 , the replacement can be achieved through the cooperation of the adjusting screw 31001 and the adjusting spring 31002 .
[0065] It should be noted that the preset connection force refers to the friction force between the adjusting spring 31002 and the adjusting clamp 3101, and this friction force is mainly adjusted by the elastic force of the adjusting spring 31002. For example, the threaded connection of the adjusting screw 31001 further compresses the adjusting spring 31002, and the preset connection force increases accordingly. On the contrary, the threaded connection of the adjusting screw 31001 reduces the degree of compression of the adjusting spring 31002, and the preset connection force decreases accordingly. Therefore, the tester can control the throwing speed of the filter to be tested by tightening or loosening the adjusting screw 31001, thereby increasing the test efficiency.
[0066] Furthermore, Figure 7 As shown, the adjusting member 3100 also includes an adjusting guide bevel block 31003, and along the length direction of the adjusting splint 3101, the side walls of the block of the adjusting guide bevel block 31003 are all inclined surfaces; the adjusting splint 3101 is provided with an adjusting guide hole 31010 with a guiding bevel, and along the length direction of the adjusting splint 3101, the side walls of the hole of the adjusting guide hole 31010 are all inclined surfaces; the adjusting guide bevel block 31003 can slide into or out of the adjusting guide hole 31010 along the guiding bevel; one end of the adjusting spring 31002 is connected and fixed to the adjusting guide block, and the other end of the adjusting spring 31002 is connected and fixed to the adjusting screw 31001 through the extrusion block, that is, the adjusting screw 31001 is screwed into the extrusion block, and the extrusion The pressing block is then connected to the adjusting spring 31002. When the adjusting splint 3101 is crimped and fixed in the adjusting slot, the adjusting guide bevel block 31003 is located in the adjusting guide hole 31010. When the adjusting splint 3101 starts to perform centrifugal motion, the adjusting guide block slides out of the adjusting guide hole 31010 along the guiding bevel, and the movement of the adjusting splint 3101 also moves along the direction of the guiding bevel, so that the adjusting splint 3101 can smoothly transition from a static state to a centrifugal motion state, that is, start the centrifugal motion in a gradual and uniform manner, and there will be no phenomenon of excessive stress concentration in a local area due to sudden separation, thereby protecting the contact surface between the adjusting splint 3101 and the adjusting slot and other structural components connected thereto.
[0067] In some embodiments, a connection structure that can be realized between the adjusting member 3100 and the adjusting splint 3101 is further provided, and the adjusting member 3100 and the adjusting splint 3101 are magnetically connected, that is, the adjusting member 3100 is a mother magnet block, and the adjusting splint 3101 is a child magnet block. The preset connection force between the adjusting member 3100 and the adjusting splint 3101 refers to the magnetic attraction force of the mother magnet block and the child magnet block. When the magnetic attraction force is less than the required centripetal force of the adjusting splint 3101, the adjusting splint 3101 will separate from the adjusting member 3100 and perform centrifugal motion.
[0068] In other embodiments, a connection structure that can be realized between the adjusting member 3100 and the adjusting splint 3101 is further provided, and the adjusting member 3100 and the adjusting splint 3101 are non-permanently adhesively connected, that is, the adjusting member 3100 and the adjusting splint 3101 are connected by temporary adhesiveness, and the preset connection force between the adjusting member 3100 and the adjusting splint 3101 refers to the adhesive force. When the adhesive force is less than the required centripetal force of the adjusting splint 3101, the adjusting splint 3101 will separate from the adjusting member 3100 and perform centrifugal movement.
[0069] It should be pointed out that the adjusting member 3100 can be magnetically connected to the adjusting splint 3101, and the adjusting member 3100 and the adjusting splint 3101 maintain an adhesive connection, then the preset connection force refers to the combined force of the magnetic attraction force and the adhesive force, and technical personnel in this field can make a choice according to actual needs.
[0070] In some specific embodiments, Figure 4 and Figure 5 As shown, a structure that can be implemented in the clamping component 31 is further provided. In addition to the first clamping portion 310 and the second clamping portion 311, the clamping component 31 also includes an angle adjustment portion 312. The angle adjustment portion 312 is arranged on the exit trajectory of the filter to be tested. The relative position of the angle adjustment portion 312 and the exit trajectory of the filter to be tested is adjustable. When the filter to be tested performs centrifugal motion, the angle adjustment portion 312 blocks one side of the filter to be tested, so that the filter to be tested is rotated out from the other side, thereby changing the exit angle of the filter to be tested. By changing the relative position of the angle adjustment portion 312 and the exit trajectory of the filter to be tested, the angle at which the filter to be tested is thrown out can be adjusted, thereby simulating different impact points when the filter to be tested falls, thereby increasing the flexibility of use of the device.
[0071] In this embodiment, the angle adjustment portion 312 is a cylindrical blocking column, so that one side of the blocking column blocks the filter to be tested, and the other side of the blocking column allows the filter to be tested to rotate outward, and Figure 5 As shown, a structure that can be implemented by the second clamping portion 311 is further provided. The second clamping portion 311 is fixedly connected to the connecting component 30. The second clamping portion 311 is provided with a second slide groove. A plurality of angle mounting slots 3110 are provided in the length direction of the second slide groove. The length direction of the second slide groove is arranged along the width direction of the second clamping portion 311, so that the plurality of angle mounting slots 3110 are arranged along the width direction of the second clamping portion 311. The plurality of angle mounting slots 3110 are used for installation of the angle adjustment portion 312. The blocking column can slide in the second slide groove. When it moves to the corresponding angle mounting slot 3110, the blocking column is fixed on the angle mounting slot 3110 by the latch 3111, that is, the blocking column can be installed in any angle mounting slot 3110, thereby changing the relative position of the angle adjustment portion 312 and the exit trajectory of the filter to be tested to simulate different impact points.

[0073] In this embodiment, if Figure 4 and Figure 5 As shown, the connecting block 300 includes a vertical connecting block 3000 and a transverse connecting block 3001. The vertical connecting block 3000 is used for connecting the first clamping portion 310 and the second clamping portion 311. The transverse connecting block 3001 is fixedly connected to the vertical connecting block 3000 and is used to connect to the rotating component 21.
[0074] In this embodiment, the external end of the connecting screw 301 is connected to a rotating handle, and the adjusting body 31000 of the first clamping part 310 is extended with a screw connecting block, that is, the adjusting body 31000 is extended into the connecting groove through the screw connecting block, and the screw connecting block is then screwed with the connecting screw 301 to realize the screw connection installation of the first clamping part 310 and the connecting screw 301.
