[0030] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0031] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation words are not used to limit the present utility model.

[0032] In order to solve the problem of poor display effect of the fault simulation device in the prior art, the present application provides a bench device and a fault simulation device having the same.

[0033] Such as Figures 1 to 4As shown in the figure, the bench device includes a workbench 10, a display structure 20 for installing electrical components, a support structure 30, and an adjustment assembly 40. The display structure 20 for installing electrical components is rotatably arranged on the workbench 10. The support structure 30 is arranged between the workbench 10 and the display structure 20 to support the display structure 20. The adjustment assembly 40 includes a first adjustment part 41 and a plurality of second adjustment parts 42. The first adjustment part 41 is arranged on the support structure 30, and each second adjustment part 42 is arranged on the display structure 20 and / or the workbench 10. The plurality of second adjustment parts 42 are arranged at intervals along a preset direction. The first adjustment part 41 and the plurality of second adjustment parts 42 are slidably matched so that the support structure 30 is movably arranged. Wherein, when the first adjustment part 41 cooperates with each second adjustment part 42, the support structure 30 rotates relative to the display structure 20 and / or the workbench 10 to adjust the flipping angle of the display structure 20.

[0034] Applying the technical solution of this embodiment, the display structure 20 of the bench device is rotatably arranged on the workbench 10. The display structure 20 is used for installing electrical components. The support structure 30 is arranged between the workbench 10 and the display structure 20 to support the display structure 20. The adjustment assembly 40 includes a first adjustment part 41 and a plurality of second adjustment parts 42. The first adjustment part 41 is arranged on the support structure 30, and each second adjustment part 42 is arranged on the display structure 20 and / or the workbench 10. The plurality of second adjustment parts 42 are arranged at intervals along a preset direction. The first adjustment part 41 and the plurality of second adjustment parts 42 are slidably matched so that the support structure 30 is movably arranged. Wherein, when the first adjustment part 41 cooperates with each second adjustment part 42, the support structure 30 rotates relative to the display structure 20 and / or the workbench 10 to adjust the flipping angle of the display structure 20. In this way, during the process of the staff installing the corresponding electrical components to display and teach the fault situation, the second adjustment part 42 cooperating with the first adjustment part 41 on the support structure 30 can be adjusted according to the actual viewing angle of the learners, so as to adjust the flipping angle of the display structure 20, so that the display angle of the display structure 20 can match the actual viewing situation, thus solving the problem of poor display effect of the fault simulation device in the prior art. At the same time, since the support structure 30 can slide through the sliding cooperation between the first adjustment part 41 and the second adjustment part 42, the staff can adjust the installation position of the support structure 30 according to the mass distribution of the electrical components on the display structure 20 to ensure that the support structure 30 has a good support effect.

[0035] It should be noted that the workbench 10 or the display structure 20 may not be provided with the second adjustment part 42, that is, the display structure 20 is supported only by the frictional force between the support structure 30 and the workbench 10 or the display structure 20.

[0036] In this embodiment, two connecting protrusions are provided on the display structure 20, and two mounting seats are provided on the tabletop of the workbench 10. The two mounting seats are arranged opposite to each other, and a part of the display structure 20 is located between the two mounting seats. The two connecting protrusions respectively extend into the mounting seats, so that the display structure 20 is rotatably arranged on the workbench 10.

[0037] In this embodiment, the rotation axis of the display structure 20 is arranged parallel to the tabletop of the workbench 10, and the rotation axis of the display structure 20 extends along the width direction of the workbench 10.

[0038] It should be noted that the extension direction of the rotation axis is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the rotation axis is arranged at an angle with the width direction of the workbench 10.

[0039] In this embodiment, the preset direction is the length direction of the workbench 10 or the height direction of the display structure 20.

[0040] It should be noted that the extension direction of the preset direction is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the preset direction is arranged at an angle with the length direction of the workbench 10.

[0041] Optionally, one of the first adjusting portion 41 and the second adjusting portion 42 is a protrusion, and the other of the first adjusting portion 41 and the second adjusting portion 42 is a recess. The protrusion extends into the recess and is slidably arranged along the extension direction of the recess; wherein, the extension direction of the recess is arranged at an angle with the preset direction. In this way, on the one hand, on the basis of realizing the sliding fit between the first adjusting portion 41 and the second adjusting portion 42, the structures of the first adjusting portion 41 and the second adjusting portion 42 are simpler, easier to process and realize, thereby reducing the processing cost of the first adjusting portion 41 and the second adjusting portion 42 and the processing difficulty of the staff; on the other hand, the structures of the first adjusting portion 41 and the second adjusting portion 42 are more flexible and diverse to adapt to different working conditions and usage requirements, thereby improving the processing flexibility of the staff. At the same time, the above setting of the recess ensures that the sliding direction of the support structure 30 is inconsistent with its rotation direction, so as to prevent the support structure 30 from sliding along its rotation direction, resulting in the deflection of the display structure 20 when the staff adjusts the setting position of the support structure 30, thereby improving the support reliability of the support structure 30.

[0042] In this embodiment, the extension direction of the recess is arranged at 90° with the preset direction.

[0043] In this embodiment, the first adjusting portion 41 is a recess and the second adjusting portion 42 is a protrusion.

[0044] In other embodiments not shown in the drawings, the first adjusting portion is a protrusion and the second adjusting portion is a recess.

[0045] As Figure 1 and Figure 2 shown, the protrusion is strip-shaped, the inner wall of the recess is arc-shaped, and the protrusion has a mating surface that matches the inner wall of the recess so that the protrusion can rotate relative to the recess. Among them, the rotation axis of the protrusion is parallel to the flipping axis of the display structure 20. In this way, the above setting enables the protrusion to rotate relative to the recess, that is, while the support structure 30 realizes its sliding action through the sliding fit between the protrusion and the recess, it can also realize its rotational movement.

[0046] In this embodiment, the upper surface of the protrusion is an arc surface.

[0047] In this embodiment, the inner wall of the recess is an arc surface, and the inner wall of the recess arranged as an arc surface forms a mating surface.

[0048] In this embodiment, since the sliding and rotation of the support structure 30 are both realized through such a simple structure of the protrusion and the recess, when the staff operates the support structure 30 to slide, a plurality of support structures 30 can be installed between the workbench 10 and the display structure 20 to further improve the support effect of the support structure 30 on the display structure 20.

[0049] Optionally, a second adjusting portion 42 is provided on both the display structure 20 and the workbench 10. There are at least two first adjusting portions 41, and at least one first adjusting portion 41 is provided at each end of the support structure 30. Wherein, one end of the support structure 30 close to the display structure 20 is the first end, and one end of the support structure 30 close to the workbench 10 is the second end. The first adjusting portion 41 on the second end cooperates with the second adjusting portion 42 on the workbench 10, so that when the first adjusting portion 41 on the first end cooperates with different second adjusting portions 42 provided on the display structure 20, the support structure 30 is rotatably arranged relative to the workbench 10; or, the first adjusting portion 41 on the first end cooperates with the second adjusting portion 42 on the display structure 20, so that when the first adjusting portion 41 on the second end cooperates with different second adjusting portions 42 provided on the workbench 10, the support structure 30 is rotatably arranged relative to the display structure 20. In this way, on the one hand, the above settings enable a cooperation relationship to exist among the support structure 30, the workbench 10, and the display structure 20, so as to improve the cooperation reliability between the support structure 30 and the workbench 10 and the display structure 20, and further improve the support reliability of the support structure 30; on the other hand, when there are multiple second adjusting portions 42 on the workbench 10 or the display structure 20, the support structure 30 can adjust its rotation angle through the first adjusting portions 41 at its two ends, thereby improving the flexibility of the number of second adjusting portions 42 provided on the workbench 10 and the display structure 20. At the same time, the above settings make the number of first adjusting portions 41 provided on the support structure 30 more flexible and diverse, so as to adapt to different working conditions and usage requirements, and also improve the processing flexibility of the staff.

[0050] In this embodiment, one first adjusting portion 41 is provided at each end of the support structure 30.

[0051] Optionally, there are multiple second adjusting parts 42 on the workbench 10. The support structure 30 includes a support body 31 and a connecting structure 32. At least one first adjusting part 41 is provided at one end of the support body 31 close to the display structure 20. The connecting structure 32 is rotatably provided at the other end of the support body 31, and at least one other first adjusting part 41 is provided on the connecting structure 32. Wherein, when the first adjusting part 41 on the connecting structure 32 cooperates with the multiple second adjusting parts 42 provided on the workbench 10 in sequence, the connecting structure 32 rotates relative to the support body 31. In this way, when the staff operates the support structure 30 to cooperate with the multiple second adjusting parts 42 provided on the workbench 10 to adjust the flipping angle of the display structure 20, the support body 31 will rotate relative to the display structure 20, and the connecting structure 32 can rotate relative to the support body 31, so that the orientation of the first adjusting part 41 provided on the connecting structure 32 can be consistent with the orientation of the second adjusting part 42 provided on the workbench 10, thereby improving the cooperation reliability between the first adjusting part 41 and the second adjusting part 42.

[0052] In this embodiment, there are five second adjusting parts 42.

[0053] It should be noted that the number of the second adjusting parts 42 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the number of the second adjusting parts 42 is two, or three, or four, or six, or seven, or more.

[0054] In this embodiment, only one second adjusting part 42 is provided on the display structure 20 to ensure that the rotation action and sliding action of the support structure 30 can be realized.

[0055] It should be noted that only one second adjusting part 42 can also be provided on the workbench 10, and multiple second adjusting parts are provided on the display structure 20. The staff can just turn the support structure 30 by 180°.

[0056] It should be noted that multiple second adjusting parts 42 are also provided on both the workbench 10 and the display structure 20, and the connecting structure 32 can be provided at both ends of the support body 31.

[0057] In this embodiment, the support structure 30 further includes a rotating shaft, and the connecting structure 32 is rotatably connected to the support body 31 through the rotating shaft.

[0058] In this embodiment, the support body 31 is rod-shaped.

[0059] In this embodiment, the connecting structure 32 is block-shaped, and the first adjusting part 41 is provided on the surface of the connecting structure 32 facing the workbench 10.

[0060] Such as Figure 1 AndFigure 3 As shown, the stand device further includes a reeling structure 50, which includes a rotatable reeling portion 51, on which at least part of the cable 1 for connecting the electrical components is wound, so that when the reeling portion 51 is rotated, the length of the cable 1 wound on the reeling portion 51 can be adjusted. In this way, the staff can operate the reeling portion 51 to rotate to reel or release the cable 1, which, on the one hand, allows the length of the cable 1 to meet the installation of different types of electrical components, thereby improving the versatility of the stand device; on the other hand, it can prevent the cable 1 from being too long, resulting in excess cable 1 on the workbench 10 or even on the ground, thereby improving the neatness of the stand device and preventing the teaching staff and learners from being tripped by the cable 1.

[0061] like Figure 3 As shown, a through hole 11 for the cable 1 to be passed through is provided on the workbench 10, and a winding structure 50 is provided on the workbench 10. The winding structure 50 and the display structure 20 are respectively located on both sides of the workbench 10. In this way, the above-mentioned setting of the through hole 11 enables the display structure 20 and the winding structure 50 to be installed on both sides of the workbench 10, so as to increase the installation area of the workbench 10 on one side for installing the display structure 20 while reducing the overall size of the workbench 10, thereby enabling the workbench to be installed with electrical components of larger size and specification, thereby improving the versatility of the stand device.

[0062] In this embodiment, the display structure 20 is installed on the upper surface of the workbench 10 .

[0063] In this embodiment, the winding structure 50 is installed on the lower surface of the workbench 10 .

[0064] Optionally, the winding portion 51 is rod-shaped, and the winding structure 50 further includes a mounting portion 52 and a partition 53. The mounting portion 52 is disposed on the workbench 10, and the mounting portion 52 has a mounting hole, and at least part of the winding portion 51 is rotatably disposed in the mounting hole. The partition 53 is sleeved on the winding portion 51, and the partition 53 is used to separate the multiple cables 1 wound on the winding portion 51. In this way, the above arrangement, on the one hand, realizes the rotatable installation of the winding portion 51 on the workbench 10 through the mounting portion 52; on the other hand, when multiple cables 1 are installed on the display structure 20 and the workbench 10, the partition 53 can separate two adjacent cables 1 wound on the winding portion 51 to avoid the two adjacent cables 1 from being entangled with each other, thereby improving the winding reliability of the winding structure 50.

[0065] In this embodiment, the mounting portion 52 is block-shaped.

[0066] In this embodiment, the separating part 53 is in a plate shape, and the side of the separating part 53 sleeved on the winding part 51 facing the workbench 10 is connected to the workbench 10, so that the separating part 53 can support the winding part 51, thereby improving the installation reliability of the winding part 51.

[0067] In this embodiment, there are two separating parts 53, and the two separating parts 53 are arranged at intervals along the extending direction of the winding part 51.

[0068] It should be noted that the number of the separating parts 53 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the separating part 53 is three, or four, or five, or six, or more.

[0069] In this embodiment, one end of the winding part 51 is located on the side of the mounting part 52 away from the workbench 10 to form an operating end, thereby facilitating the operator to operate the operating end to drive the winding part 51 to rotate.

[0070] As Figure 1 and Figure 2 shown, the display structure 20 includes a plate-shaped display body 21, a mounting plate 22 and a controller 23. The plate-shaped display body 21 is rotatably arranged on the workbench 10. The mounting plate 22 is arranged on the plate-shaped display body 21, and the mounting plate 22 has a through hole 221 for the cable 1 of the electrical component to pass through. Among them, there are at least two mounting plates 22, and the at least two mounting plates 22 are arranged oppositely to surround and form a mounting space for mounting the electrical components. The controller 23 is arranged on the plate-shaped display body 21 and on the side of the mounting plate 22 away from the mounting space. The controller 23 is electrically connected to the electrical component to control at least one of the magnitude of the operating current and the magnitude of the operating voltage of the electrical component; and / or, the bench device further includes a bearing structure 60. The workbench 10 includes a workbench main body 12 and support legs 13 arranged on the workbench main body 12. The bearing structure 60 is arranged on the support legs 13. In this way, on the one hand, the above settings can mount the electrical components through the mounting space formed by the mounting plate 22, thereby reducing the difficulty for the operator to install the electrical components; on the other hand, the controller can control the magnitude of the operating current and the magnitude of the operating voltage of the electrical component to simulate different electrical faults, thereby improving the versatility of the bench device. At the same time, the bearing structure 60 can be used to mount some electrical components with too large volume or mass, further increasing the types and numbers of the electrical components on the bench device, thereby improving the versatility of the bench device.

[0071] In this embodiment, there are six mounting plates 22, and two mounting plates 22 are arranged oppositely to surround and form a mounting space, that is, three groups of electrical components can be mounted on the display structure 20 to realize the simulation of the common three-phase current of the electrical system.

[0072] It should be noted that the number of installation plates 22 is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the number of installation plates 22 is two, or three, or four, or five, or seven, or eight, or more.

[0073] In this embodiment, the connecting protrusion is provided on the plate-shaped display body 21.

[0074] As Figure 1 and Figure 4 shown, this embodiment also provides a fault simulation device, which includes a bench device and electrical components. The electrical components include a cable 1, a switch device 2, a resistor 3, an overcurrent protector 4 and a grounding device 5. The switch device 2 is arranged on the workbench 10 of the bench device. The resistor 3 is arranged in the installation space of the display structure 20 of the bench device. The overcurrent protector 4 and / or the grounding device 5 are arranged on the bearing structure 60 of the bench device. The switch device 2, the resistor 3, the overcurrent protector 4, the grounding device 5 and the controller 23 of the display structure 20 are electrically connected through the cable 1. Among them, the bench device is the above-mentioned bench device. In this way, the above settings of the electrical components enable the fault simulation device to simulate electrical grounding faults. At the same time, since the fault simulation device adopts the bench device, the display effect of the fault simulation device is better, and the redundant cable 1 can be stored through the winding structure 50, greatly improving the neatness of the fault simulation device.

[0075] In this embodiment, the switch device 2 is a circuit breaker, and the circuit breaker is fixed on the upper surface of the workbench 10. Both ends of the circuit breaker are electrically connected to the cable 1 respectively, so as to control the switch state of the fault simulation device.

[0076] The cable 1 led out from the circuit breaker is electrically connected to the controller 23. The controller 23 is electrically connected to the installation plate 22. A resistor 3 is installed between the two relatively arranged installation plates 22. The resistor 3 is electrically connected to the two relatively arranged installation plates 22. After the cable 1 led out from the lower installation plate 22 is wound around the winding part 51, it is electrically connected to the overcurrent protector 4 arranged on the bearing structure 60. The end of the cable 1 led out from the overcurrent protector 4 is provided with a grounding rod 501. The grounding rod 501 is arranged in the grounding device 5 on the ground.
