Description

Technical Field

[0001] The invention relates to the technical field of training and teaching, and specifically provides a high-voltage connector plugging and unplugging training device combining 3D virtuality and reality. Background Art

[0002] The combination of 3D virtuality and reality is, in layman's terms, a 3D projection technology. High-voltage connectors are important components in electrical equipment, usually consisting of plugs, sockets, insulators, contacts, seals and other parts. During electrical operations, high-voltage connectors need to be manually plugged and unplugged. During this process, operators need to be very careful and must strictly follow the operating specifications to perform the plugging and unplugging actions. Therefore, professional trainers are needed to provide strict training and teaching to operators in the early stages. The high-voltage connector plugging and unplugging training device that combines 3D virtuality and reality uses 3D projection technology to simulate scenes in the actual application of high-voltage connectors, and projects images in different actual scenes onto an electronic whiteboard, thereby providing trainees with more realistic training scenes, thereby improving the effectiveness of high-voltage connector plugging and unplugging training.

[0003] The invention with application number 201811641132.7 discloses a stereoscopic teaching system and teaching method based on virtual reality technology. The media source module in the stereoscopic teaching system transmits the stored picture information to the 3D graphics card and sound card integration under the control of the coordination controller. The 3D graphics card and sound card integration stores the picture information transmitted by the media source module in the memory of the 3D graphics card and sound card integration. The 3D graphics card and sound card integration retrieves the information from the memory and converts it into a projection signal for controlling the 3D projector. The 3D graphics card and sound card integration transmits the projection signal to the 3D projector through the HDMI data cable. The 3D projector converts the projection signal into a light signal and projects it onto the electronic whiteboard. The observer wears 3D glasses for observation.

[0004] However, the existing technology lacks a training device that combines 3D projection technology with high-voltage connector plugging and unplugging training, which results in poor training results for trainees during the actual training process, thereby affecting the results of the actual plugging and unplugging training. At the same time, the existing plugging and unplugging training device does not have the function of training and cultivating trainees to insert and unplug high-voltage connectors at a high level when training personnel. If the personnel cannot obtain a good training effect, then in the actual plugging and unplugging process of the high-voltage connector, there will not only be safety hazards, but also damage to the high-voltage connector plug and socket.

[0005] Therefore, the present invention proposes a high-voltage connector plugging and unplugging training device that combines 3D virtuality and reality to make up for and improve the deficiencies of the prior art. Summary of the invention

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] Embodiments of the present invention

[0039] Embodiment 1 of the present invention:

[0040] like Figure 1As shown, a high-voltage connector plugging and unplugging training device combining 3D virtuality and reality includes a training platform 1, a vertical board 11 and 3D glasses (not shown in the figure). A vertical board 11 is fixedly arranged on one side of the top surface of the training platform 1, and an electronic whiteboard 12 is arranged on the vertical board 11. A projector 13 is also arranged on the top of the vertical board 11 close to the electronic whiteboard 12. The projector 13 has a 3D projection function. The 3D picture is projected on the electronic whiteboard 12 through the projector 13. The trainee can watch the picture on the electronic whiteboard 12 by wearing 3D glasses, thereby simulating the use scenario of the high-voltage connector, thereby improving the authenticity of the training process. Compared with the method of simply using a plugging and unplugging training device in the prior art, the combination of virtual pictures and real objects is used to facilitate the trainee to better train and improve the training and teaching effects; the above-mentioned electronic whiteboard 12, 3D glasses and projector 13 are all existing well-known technologies. A simulation table 14 is fixedly connected to the top surface of the training table 1. Two socket seats 15 are symmetrically arranged on the side of the simulation table 14 away from the electronic whiteboard 12. Two high-voltage connection plugs 16 are arranged on the training table 1, and the high-voltage connection plugs 16 are plug-matched with the socket seats 15. The simulation table 14, the socket seats 15 and the high-voltage connection plugs 16 are used to simulate the actual high-voltage connector.

[0041] Furthermore, if Figures 1 to 3 As shown, a support clip 101 is fixedly connected to one side of the upper surface of the training platform 1 away from the vertical plate 11. The support clip 101 is provided with a snap-in for horizontally placing the high-voltage connecting plug 16, and the support clip 101 is made of elastic rubber material as a whole. When the high-voltage connecting plug 16 is not in use, the high-voltage connecting plug 16 can be fixed by its elastic clamping.

[0042] like Figures 1 to 7As shown, a plug-in training mechanism is provided on the upper surface of the training platform 1, and the plug-in training mechanism includes two slotted plates 21 symmetrically fixedly connected to the upper surface of the training platform 1, and the tops of the two slotted plates 21 are provided with rectangular openings, and the interiors of the two slotted plates 21 are provided with empty slots 22, and the empty slots 22 are connected to the rectangular openings on the tops of the slotted plates 21, and extension plates 24 are slidably provided in the rectangular openings on the tops of the two slotted plates 21, and the tops of the two extension plates 24 are fixedly connected with concave plates 23, and the two extension plates 24 can be horizontally displaced in the corresponding rectangular openings, and can also be displaced up and down, that is to say, when the extension plates 24 are initially, the outer walls on both sides thereof are in contact with the inner walls of the rectangular openings. The positions of the two grooved plates 21 and the two concave plates 23 correspond to the positions of the two jack sockets 15, and when the high-voltage connection plug 16 is placed horizontally on the concave plates 23, the high-voltage connection plug 16 and the jack sockets 15 correspond to each other. That is to say, when the trainee holds the high-voltage connection plug 16 and pushes the concave plates 23 to move horizontally toward the jack sockets 15, the high-voltage connection plug 16 can be inserted into the corresponding jack sockets 15. Two twin plates 231 are symmetrically fixedly arranged on one side of the two concave plates 23 close to the simulation table 14, and two extension plates 24 are rotatably connected to the side away from the concave plates 23 with rollers 25, and the two rollers 25 are both in contact with the groove surface at the bottom of the inner cavity of the adjacent empty slot 22. Two limit bars 26 are symmetrically fixedly arranged on the extension plates 24, and a plurality of array plates 27 are evenly fixedly connected at the positions corresponding to the two limit bars 26 on the groove surface at the top of the inner cavity of the empty slot 22, and the two limit bars 26 are both located below the array plate 27, and the limit bars 26 and the array plate 27 are both rectangular block structures. The extension plate 24 is symmetrically fixedly connected to the outer wall below the two limit bars 26 with two mirror plates 28, and the upper and lower surfaces of the two mirror plates 28 are connected with spring plates 29. The groove surfaces on both sides of the inner cavity of the empty groove 22 are provided with two guide plates 210, and the two guide plates 210 on the same side are distributed in parallel up and down, specifically, the upper guide plate 210 is arranged between the limit bar 26 and the mirror plate 28 on the corresponding side, and the lower guide plate 210 is arranged below the mirror plate 28 on the corresponding side. There is a gap between the limit bar 26 and the upper guide plate 210, and the two spring plates 29 on the same mirror plate 28 are located between the two guide plates 210 on the corresponding side. The spring plate 29 is composed of a vertical spring and a plate body, and one end of the vertical spring is fixedly connected to the mirror plate 28, and the other end of the vertical spring is fixedly connected to the plate body, wherein the plate body is fitted with the adjacent guide plate 210. Initially, the vertical spring in the spring plate 29 is in a compressed state, and at this time the plate body is tightly attached to the outer surface of the guide plate 210. The cooperation between the two spring plates 29 and the guide plate 210 ensures that the extension plate 24 and the concave plate 23 are initially in a vertical state, and when the plate body is tightly attached to the outer surface of the guide plate 210, the plate body can slide horizontally along the surface of the guide plate 210.

[0043] During use: When the trainees are doing plug-in and unplug training, the trainees can turn on the electronic whiteboard 12 and the projector 13, and project a virtual high-voltage connector usage scene on the electronic whiteboard 12 through the projector 13. Then, the trainees can move to the front of the training platform 1, and then manually take out a high-voltage connection plug 16 from the holder 101, and then point the insertion end of the high-voltage connection plug 16 toward the concave plate 23, and move the high-voltage connection plug 16 horizontally, so that the outer wall of the side of the high-voltage connection plug 16 close to the insertion end is in conflict with the two twin plates 231, and the high-voltage connection plug 16 is placed horizontally on the concave plate 23. Then, the trainees pinch the outer surface of the high-voltage connection plug 16 away from the simulation platform 14, and push the concave plate 23, the extension plate 24, the roller 25 and the components on the roller 25, gradually displace horizontally in the direction close to the jack seat 15, until the insertion end of the high-voltage connection plug 16 is completely inserted into the corresponding jack seat 15, so as to complete the single insertion action training of the high-voltage connector.

[0044] When the high-voltage connection plug 16 is placed horizontally on the concave plate 23, the concave plate 23 can prevent the trainees from directly holding the insertion end of the high-voltage connection plug 16 with their hands during training. This can cultivate the trainees' safety awareness during the actual plugging and unplugging of high-voltage connectors and prevent them from unconsciously touching the insertion end of the high-voltage connection plug 16 with their hands, which may cause electric shock in subsequent actual operations.

[0045] When the trainer pushes the concave plate 23, the extension plate 24 and the high-voltage connection plug 16 to move horizontally, the roller 25 will be moved synchronously inside the slot 22, and the limit bar 26, the mirror plate 28 and the spring plate 29 will be displaced synchronously. If the trainer holds the high-voltage connection plug 16 and moves horizontally, and an unstable situation occurs during the movement, that is, the high-voltage connection plug 16, the concave plate 23, the extension plate 24, the limit bar 26, the mirror plate 28 and the spring plate 29 are tilted to one side as a whole, please refer to the detailed description. Figure 7As the limit strip 26 tilts, the top surface of the limit strip 26 is no longer flush with the bottom surface of the array plate 27, and one side of the top surface of the limit strip 26 is higher than the bottom surface of the array plate 27 (if the limit strip 26 is located directly below the array plate 27 when tilted, the limit strip 26 will conflict with the bottom surface of the array plate 27). At the same time, as the spring plate 29 tilts, the vertical spring is deformed, so that the surface of the plate body away from the vertical spring is always in contact with the outer surface of the guide plate 210. In this way, under the cooperation of the array plate 27 and the limit bar 26, the trainee will encounter resistance when pushing the high-voltage connection plug 16, and then the trainee can manually adjust the horizontality of the high-voltage connection plug 16, the concave plate 23 and the extension plate 24 until the limit bar 26 returns to the initial state (that is, the top surface of the limit bar 26 is flush with the bottom surface of the array plate 27), and then continue to push the high-voltage connection plug 16 horizontally to displace, and finally make the high-voltage connection plug 16 horizontally aligned with the corresponding socket seat 15 and inserted into the socket seat 15. When the trainee needs to pull out the high-voltage connection plug 16, he can hold the concave plate 23 with one hand and the high-voltage connection plug 16 with the other hand, and then pull the high-voltage connection plug 16 out of the socket seat 15 horizontally, and at the same time, the concave plate 23 is also caused to move horizontally in the direction away from the socket seat 15. During this process, the guide plate 210, the spring plate 29, the roller 25, the empty slot 22, the limit strip 26 and the array plate 27 can play a guiding role in the process of pulling out the high-voltage connection plug 16, thereby preventing the high-voltage connection plug 16 from being pulled out at an angle and causing damage to the socket 15.

[0046] Therefore, during the training process of plugging and unplugging the high-voltage connector, the trainees use the cooperation of the set limit strips 26, array plates 27 and other components to encourage the trainees to always keep the high-voltage connection plug 16 horizontal and insert it into the jack socket 15, so as to avoid damage to the jack socket 15 due to the tilt of the high-voltage connection plug 16 during actual operation. This effectively regulates the horizontality of the trainees' insertion action and helps the trainees develop correct operating habits.

[0047] Embodiment 2 of the present invention:

[0048] like Figures 1 to 3As shown, the high-voltage connector plugging and unplugging training device combining 3D virtuality and reality also includes a prompt component, which includes a convex rod plate 31 fixedly connected to the concave plate 23 on the side close to the simulation platform 14, and a convex rod plate 31 is arranged on each of the two concave plates 23. A support plate 32 is fixedly arranged on the top surface of the training platform 1, and two warning lights 33 are fixedly installed on the side of the support plate 32 close to the convex rod plate 31. Two push-type switches 34 are also fixedly installed on the side of the support plate 32 close to the convex rod plate 31. The two push-type switches 34 are respectively located on both sides of the two warning lights 33. The two convex rod plates 31 are both composed of a horizontal plate and a rod body, wherein the horizontal plate is fixed to the side of the concave plate 23 close to the simulation platform 14, and the rod body is fixed to the side of the horizontal plate close to the simulation platform 14. The two push-type switches 34 are respectively located on the movement paths of the two rod bodies. Specifically, when the convex rod plate 31 moves to the final position along with the concave plate 23, the rod body just contacts the corresponding push-type switch 34. The two push switches 34 control the two warning lights 33 respectively, and both the two warning lights 33 and the push switches 34 are powered by an external battery.

[0049] When in use: Considering that in the process of inserting the high-voltage connection plug 16 into the socket seat 15 in the actual high-voltage connector, it is necessary to avoid over-insertion and under-insertion. In the process of inserting the high-voltage connection plug 16 into the socket seat 15, the protruding rod plate 31 will also be driven to move synchronously. When the high-voltage connection plug 16 is inserted into the socket seat 15, the rod body in the protruding rod plate 31 will contact the push switch 34, and then the warning light 33 will be controlled by the push switch 34 to start. After the high-voltage connection plug 16 is pulled out, the rod body in the protruding rod plate 31 no longer contacts the push switch 34, and the push switch 34 controls the warning light 33 to automatically turn off.

[0050] Therefore, after the trainee manually inserts the high-voltage connection plug 16 into the interior of the socket 15, the cooperation of the protruding rod plate 31 and the warning light 33 and other components is utilized, and the warning light 33 is turned on to provide a clear visual indication, so that the trainee can clearly know that the high-voltage connection plug 16 has been inserted into the correct position, thereby avoiding poor connection or damage to the equipment due to insufficient insertion depth or excessive insertion, thereby improving the accuracy of the trainee's operation.

[0051] Embodiment 3 of the present invention:

[0052] like Figure 1 , Figures 8 to 12As shown, the high-voltage connector plugging and unplugging training device combining 3D virtual reality and reality also includes a functional mechanism, which includes two L-shaped plates 41 respectively fixedly connected to the two concave plates 23, and a plurality of blocking plates 42 are evenly fixedly arranged on the bottom surface of the L-shaped plate 41. A torsion spring claw 43 is rotatably connected to each blocking plate 42. The torsion spring claw 43 is composed of a ratchet and a torsion spring. The ratchet is rotatably connected to the blocking plate 42, and one end of the torsion spring is fixedly connected to the blocking plate 42, and the other end is fixedly connected to the ratchet. The side of each blocking plate 42 away from the simulation platform 14 is open, and the side close to the simulation platform 14 is provided with a vertical baffle. Initially, one side surface of the ratchet in the torsion spring claw 43 is in contact with the vertical baffle of the blocking plate 42, that is, the ratchet is supported by the vertical baffle, so that the ratchet can only rotate in the direction away from the simulation platform 14. The top of the training platform 1 is symmetrically connected to two combination gears 44, which are located between two slotted plates 21. The combination gears 44 are composed of a large gear and a small gear, wherein the large gear is located on the horizontal motion path of the adjacent torsion spring claws 43. Two double slot frames 45 are fixedly connected to the top of the training platform 1 and at positions corresponding to the two combination gears 44. The two double slot frames 45 are slidably connected to bracket plates 46. The two bracket plates 46 are fixedly connected to the side of the adjacent combination gears 44. The racks 47 are meshed with the adjacent small gears. Initially, the top teeth of the racks 47 are meshed with the teeth of the small gears. The two socket seats 15 are both plugged with a cover 48 on the side close to the bracket plates 46. Initially, the cover 48 is plugged on the socket seat 15 to protect the socket seat 15. This cover 48 is also a sealing cover that is generally provided on the socket seat 15 during the use of the actual high-voltage connector. A lens 49 is fixedly provided on one side of the two covers 48 away from the jack seat 15 , and a bracket for placing the covers 48 is provided on the top of the two bracket plates 46 .

[0053] Furthermore, if Fig.11 , Fig.12 As shown, the brackets on the top of the two bracket plates 46 are composed of an upper flared portion and a lower vertical portion. The flared portion is convenient for trained personnel to place the cover body 48 downward into the bracket, while the vertical portion just supports the two sides of the cover body 48. Specifically, rectangular blocks are symmetrically arranged on both sides of the cover body 48, and the rectangular blocks are placed in the vertical portion of the bracket.

[0054] During use: Considering that in the actual use of the high-voltage connector, the personnel need to observe whether the high-voltage connection plug 16 is worn and damaged each time the high-voltage connection plug 16 is pulled out, so it is also necessary to cultivate self-inspection awareness for the trainees. Before the high-voltage connection plug 16 is inserted into the jack seat 15, the trainees can manually separate the cover body 48 from the jack seat 15 and put the cover body 48 into the bracket at the top of the bracket plate 46. In the process of horizontal displacement of the concave plate 23 toward the direction close to the jack seat 15, it will also drive the torsion spring claw 43 to move synchronously. During this process, when the torsion spring claw 43 moves to contact the large gear in the combination gear 44, the ratchet in the torsion spring claw 43 will rotate to the side away from the simulation platform 14. In the process, the torsion spring is deformed by force, and as the ratchet rotates, it will not drive the large gear in the combination gear 44 to rotate, that is, the small gear will not rotate. In the process of the trainee pulling out the high-voltage connection plug 16 and driving the high-voltage connection plug 16 and the concave plate 23 to move horizontally in the opposite direction, when the pawl of the torsion spring pawl 43 contacts the large gear, the pawl will drive the large gear to rotate under the blocking effect of the vertical baffle of the blocking plate 42, thereby driving the small gear to rotate synchronously, and as the small gear rotates, under the limiting effect of the double-slot frame 45, the rack 47 will be prompted to gradually move up, thereby driving the bracket plate 46 and the cover body 48 placed in the bracket of the bracket plate 46 to move up synchronously, and when the high-voltage connection After the plug 16 is separated from the socket 15 by a certain distance, the cover 48 and the lens 49 can be moved upward to between the socket 15 and the insertion end of the high-voltage connecting plug 16. At this time, the torsion spring claw 43 on the L-shaped plate 41 is still in conflict with the large gear. During the upward movement of the cover 48, the trainee can intuitively see the movement of the cover 48. When the upward movement of the cover 48 and the lens 49 stops, the trainee can see the usage of the insertion end of the high-voltage connecting plug 16 through the mirror reflection of the lens 49, such as whether there is any wear and damage.

[0055] Therefore, when the trainee is unplugging the high-voltage connection plug 16, the gradually upwardly moving cover 48 and lens 49 remind the trainee that the use of the high-voltage connection plug 16 is required, thereby enhancing the trainee's self-inspection awareness.

[0056] When the trainee has finished observing, the cover 48 can be moved up and taken out from the bracket of the bracket plate 46, and then the cover 48 can be inserted back into the socket seat 15. As the concave plate 23 continues to reset horizontally in the opposite direction, when the torsion spring claws 43 on the L-shaped plate 41 do not conflict with the large gear, the bracket plate 46 and the rack 47 automatically move downward under the action of gravity and reset to the initial position. At the same time, the cover 48 needs to be manually removed before the high-voltage connection plug 16 is inserted, and in the process of pulling out the high-voltage connection plug 16, the upwardly moved cover 48 is used to remind the trainee that the cover 48 needs to be manually inserted back into the socket seat 15, thereby simulating the actual use and operation steps of the high-voltage connector, thereby providing the trainee with more realistic and effective training steps.
