Description

Technical Field

[0001] This invention relates to the field of electrical cabinet testing technology, specifically to an electrical cabinet seismic testing device and method. Background Technology

[0002] Seismic resistance is an important attribute of electrical cabinets. Cabinets with excellent seismic resistance can continue to operate during an earthquake.

[0003] Conventional methods for testing the seismic resistance of server racks involve applying vibrations with set accelerations and frequencies to the vertical axis, front-to-rear axis, and side-to-side axis of the rack to simulate real ground motion. However, existing seismic testing equipment consists of vertical vibration simulators and horizontal vibration simulators, which have low integration levels. During testing, the electrical cabinets need to be moved between different simulators, resulting in low testing efficiency.

[0004] Based on this, the present invention designs an electrical cabinet seismic testing device and method to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an electrical cabinet seismic testing device and method.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An electrical cabinet seismic testing device includes a base, a longitudinal support plate, a transverse support plate, a vertical support plate, and a loading plate;

[0008] The longitudinal moving support plate is mounted on the base platform in a longitudinal direction via a longitudinal moving limiting component. The transverse moving support plate is mounted on the longitudinal moving support plate in a transverse direction via a transverse moving limiting component. The vertical moving support plate is mounted on the transverse moving support plate in a vertical direction via a vertical moving limiting component. A tooling plate for installing the electrical cabinet is fixedly installed on the vertical moving support plate.

[0009] The base is equipped with a longitudinal sway control mechanism, a transverse sway control mechanism and a vertical sway control mechanism. The output ends of the three mechanisms are movably connected to the longitudinal support plate, the transverse support plate and the vertical support plate, respectively. Locking components are installed between the longitudinal support plate and the base, between the transverse support plate and the longitudinal support plate, and between the vertical support plate and the transverse support plate.

[0010] An anti-tipping safety mechanism is also installed on the base. This mechanism is used to hold the top of the electrical cabinet in place to prevent it from tipping over and injuring people nearby.

[0011] Furthermore, the longitudinal rocking control mechanism includes a longitudinal drive arm and a longitudinal adjustable drive assembly. The longitudinal adjustable drive assembly is mounted on a base and includes a rotary drive device, a limit rail, a limit slider, an adjusting screw, and a bracket. The bracket is fixedly mounted on the base, and the rotary drive device is mounted on the bracket. The limit rail is fixedly mounted on the output end of the rotary drive device, and the limit slider is slidably connected to the limit rail. The adjusting screw is rotatably connected to the limit rail through a bearing, and the limit slider is threadedly connected to the adjusting screw through a threaded sleeve. The two ends of the longitudinal drive arm are hinged to the longitudinal support plate and the limit slider, respectively.

[0012] Furthermore, the lateral sway control mechanism includes a lateral drive arm, a lateral adjustable drive assembly, and a connecting assembly. The lateral adjustable drive assembly is mounted on the base and has the same structure as the longitudinal adjustable drive assembly. The connecting assembly is mounted on the side of the lateral support plate, and the two ends of the lateral drive arm are connected to the connecting assembly and the adjustable drive assembly, respectively.

[0013] Furthermore, the connecting assembly includes a first guide rail, a first connecting plate, a connecting rod, a second linear guide rail, and a second connecting plate. The first guide rail is fixedly installed on the side of the transverse support plate, and the first connecting plate is longitudinally slidable on the first guide rail via a slider. The second linear guide rail is fixedly installed on the base, and the second connecting plate is transversely slidable on the second linear guide rail via a slider. The two ends of the connecting rod are fixedly connected to the first connecting plate and the second connecting plate, respectively. The two ends of the transverse drive arm are hinged to the second connecting plate and the limiting slider of the transverse adjustable drive assembly, respectively.

[0014] Furthermore, the vertical sway control mechanism includes a vertical drive arm and a vertical adjustment drive assembly. The vertical adjustment drive assembly is mounted on the base and has the same structure as the longitudinal adjustment drive assembly. The two ends of the vertical drive arm are respectively hinged to the lower end of the vertical movement support plate and the limiting slider of the vertical adjustment drive assembly.

[0015] Furthermore, the anti-tipping safety mechanism includes a boom, a fixed chain, a lifting ring, and hanging ropes. The boom is fixedly installed on the base platform, the upper end of the fixed chain is fixedly connected to the top of the boom, and the lower end of the fixed chain is fixedly connected to the lifting ring. Two hanging ropes are provided and threaded through the lifting ring.

[0016] Furthermore, the two hanging ropes are arranged in a crisscross pattern, with each end of the rope being used to connect to two hanging rings diagonally distributed on the top of the electrical cabinet.

[0017] To better achieve the objectives of this invention, this invention also provides a testing method for an electrical cabinet seismic testing device, comprising the following steps:

[0018] Step 1: Install and fix the electrical cabinet on the loading plate, connect the lifting ring on the top of the electrical cabinet to the hanging rope, and install displacement gauges and accelerometers on the four sides and the top of the electrical cabinet at the set intervals;

[0019] Step 2: The vertical and horizontal support plates are fixed relatively by locking components. The vertical and horizontal swaying control mechanisms are used in conjunction to control the swaying of the vertical and horizontal support plates, simulating the combined vibration effect in the horizontal direction.

[0020] Step 3: Fix the longitudinal support plate and the base, as well as the transverse support plate and the longitudinal support plate, relatively by locking the components. Connect the vertical drive arm to the lower end of the vertical support plate. Control the vertical support plate to shake by the vertical rocking control mechanism to simulate the vertical vibration effect.

[0021] Step 4: Record the readings of the displacement gauge and accelerometer;

[0022] Step 5: Configure various test specimens in different modes inside the electrical cabinet. Repeat steps 2 to 4 after each configuration to test the seismic performance of the electrical cabinet under different loads and load distributions.

[0023] Compared with the prior art, the advantages of this invention are as follows: the lateral sway control mechanism, the vertical sway control mechanism, and the anti-tipping safety mechanism can control the swaying of the longitudinal support plate, the transverse support plate, and the vertical support plate, respectively. The longitudinal support plate and the transverse support plate can be controlled independently to simulate the swaying of the front-rear axis or the side-side axis of the electrical cabinet. The two can work together to simulate the combined vibration effect in the horizontal direction. The vertical support plate can simulate the swaying of the vertical axis of the electrical cabinet. During the testing process, the anti-tipping safety mechanism can provide safety protection by holding the top of the electrical cabinet in place when it is tilted due to vibration, thus preventing injury to surrounding personnel.

[0024] The locking components enable the longitudinal support plate to be fixed relative to the base, the transverse support plate and the longitudinal support plate, or the vertical support plate and the transverse support plate. This allows for different types of vibration testing of the electrical cabinet without the need for handling, effectively improving the testing efficiency of the electrical cabinet and facilitating the testing operation. At the same time, the transverse sway control mechanism, the vertical sway control mechanism, and the anti-tipping safety mechanism are all located on the base and are not affected by vibration, thereby increasing the service life of the equipment.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0037] In some embodiments, please refer to the accompanying drawings. Figures 1-7 An electrical cabinet seismic testing device includes a base 10, a longitudinal support plate 11, a transverse support plate 12, a vertical support plate 13, and a loading plate 14.

[0038] The longitudinal support plate 11 is mounted on the base 10 in a longitudinally sliding manner through the longitudinal movement limiting component. The transverse support plate 12 is mounted on the longitudinal support plate 11 in a transverse sliding manner through the transverse movement limiting component. The vertical support plate 13 is mounted on the transverse support plate 12 in a vertically sliding manner through the vertical movement limiting component. A tooling plate 14 for mounting the electrical cabinet 7 is fixedly mounted on the vertical support plate 13.

[0039] In this embodiment, the longitudinal support plate 11 is also equipped with a plurality of buffer pads, which are used to buffer the vertical support plate 13 when it falls.

[0040] In some embodiments, both the longitudinal movement limiting component and the transverse movement limiting component employ a guide rail slider limiting structure.

[0041] In some embodiments, the vertical movement limiting component adopts a sliding rod and sleeve limiting structure.

[0042] The base 10 is equipped with a longitudinal rocking control mechanism 2, a transverse rocking control mechanism 3 and a vertical rocking control mechanism 4. The output ends of the three mechanisms are movably connected to the longitudinal support plate 11, the transverse support plate 12 and the vertical support plate 13, respectively. Locking components 6 are installed between the longitudinal support plate 11 and the base 10, between the transverse support plate 12 and the longitudinal support plate 11, and between the vertical support plate 13 and the transverse support plate 12.

[0043] In some embodiments, the locking component 6 adopts a pin locking structure, which enables the longitudinal support plate 11 to be fixed relative to the base 10, the transverse support plate 12 and the longitudinal support plate 11 or the vertical support plate 13 and the transverse support plate 12.

[0044] The base 10 is also equipped with an anti-tipping safety mechanism 5, which is used to hold the top of the electrical cabinet 7 to prevent the electrical cabinet 7 from tipping over and injuring people around it.

[0045] In this invention, the lateral sway control mechanism 3, the vertical sway control mechanism 4, and the anti-tipping safety mechanism 5 can respectively control the swaying of the longitudinal support plate 11, the transverse support plate 12, and the vertical support plate 13. The longitudinal support plate 11 and the transverse support plate 12 can be controlled independently to simulate the swaying of the front-rear axis or the side-side axis of the electrical cabinet 7. The two can work together to simulate the combined vibration effect in the horizontal direction. The vertical support plate 13 can simulate the swaying of the vertical axis of the electrical cabinet 7. During the testing process, the anti-tipping safety mechanism 5 can provide safety protection by holding the top of the electrical cabinet 7 in place when it is tilted due to vibration, thus preventing injury to surrounding personnel.

[0046] The locking component 6 can fix the longitudinal support plate 11 relative to the base 10, the transverse support plate 12 and the longitudinal support plate 11, or the vertical support plate 13 and the transverse support plate 12, so that the electrical cabinet 7 can be subjected to different types of vibration detection when it is loaded on the workpiece plate 14 without being moved. This effectively improves the detection efficiency of the electrical cabinet 7 and facilitates the detection operation. At the same time, the transverse sway control mechanism 3, the vertical sway control mechanism 4 and the anti-tipping safety mechanism 5 are all located on the base 10 and will not be affected by vibration, thereby improving the service life of the equipment.

[0047] The longitudinal rocking control mechanism 2 includes a longitudinal drive arm 21 and a longitudinal adjustable drive assembly. The longitudinal adjustable drive assembly is mounted on the base 10 and includes a motor 22, a turntable 23, a limiting rail 24, a limiting slider 25, an adjusting screw 26, and a bracket 27. The bracket 27 is fixedly mounted on the base 10. The turntable 23 is rotatably mounted on the top of the bracket 27 via bearings. The motor 22 is fixedly connected to the bracket 27, and the output end of the motor 22 is fixedly connected to the turntable 23. The limiting rail 24 is fixedly mounted on the turntable 23 and distributed radially along the turntable 23. The limiting slider 25 is slidably connected to the limiting rail 24. The adjusting screw 26 is rotatably connected to the limiting rail 24 via bearings, and the limiting slider 25 is threadedly connected to the adjusting screw 26 via a threaded sleeve. The two ends of the longitudinal drive arm 21 are hinged to the longitudinal support plate 11 and the limiting slider 25, respectively.

[0048] The lateral sway control mechanism 3 includes a lateral drive arm 31, a lateral adjustable drive assembly, and a connecting assembly. The lateral adjustable drive assembly is mounted on the base 10 and has the same structure as the longitudinal adjustable drive assembly. The connecting assembly is mounted on the side of the transverse support plate 12. The two ends of the lateral drive arm 31 are respectively connected to the connecting assembly and the adjustable drive assembly.

[0049] The connecting assembly includes a first guide rail 32, a first connecting plate 33, a connecting rod 34, a second linear guide rail 35, and a second connecting plate 36. The first guide rail 32 is fixedly installed on the side of the transverse support plate 12, and the first connecting plate 33 is mounted on the first guide rail 32 in a longitudinal direction via a slider. The second linear guide rail 35 is fixedly installed on the base 10, and the second connecting plate 36 is mounted on the second linear guide rail 35 in a transverse direction via a slider. The two ends of the connecting rod 34 are fixedly connected to the first connecting plate 33 and the second connecting plate 36, respectively. The two ends of the transverse drive arm 31 are hinged to the second connecting plate 36 and the limiting slider 25 of the transverse adjustable drive assembly, respectively.

[0050] The vertical sway control mechanism 4 includes a vertical drive arm 41 and a vertical adjustment drive assembly. The vertical adjustment drive assembly is mounted on the base 10 and has the same structure as the longitudinal adjustment drive assembly. The two ends of the vertical drive arm 41 are respectively hinged to the lower end of the vertical movement support plate 13 and the limiting slider 25 of the vertical adjustment drive assembly.

[0051] In some embodiments, the hinge shafts of the longitudinal drive arm 21 and the longitudinal support plate 11, the transverse drive arm 31 and the transverse support plate 12, and the vertical drive arm 41 and the vertical support plate 13 can all be detached, so that the normal operation of other working arms will not be affected when one drive arm is not working.

[0052] In this invention, the motor 22 of the longitudinally adjustable drive assembly drives the limiting slider 25 to rotate via the turntable 23, causing the limiting slider 25 and the longitudinal drive arm 21 to form a crank-rocker structure. This causes the longitudinal support plate 11 to reciprocate linearly in the longitudinal direction, applying longitudinal vibration to the electrical cabinet 7. Furthermore, by rotating the adjusting screw 26, the limiting slider 25 can be moved along the limiting track 24, changing the distance between the limiting slider 25 and its rotation center. This adjusts the longitudinal reciprocating stroke of the longitudinal support plate 11, and, in conjunction with changes in the speed of the motor 22, ultimately achieves the desired effect. The longitudinal vibration amplitude and frequency of the electrical cabinet 7 can be adjusted to meet the needs of various vibration simulations. Similarly, the lateral adjustment drive assembly can drive the second connecting plate 36 to make reciprocating linear motion in the lateral direction along the second linear guide rail 35. With the cooperation of the first guide rail 32, the first connecting plate 33 and the connecting rod 34, it can still drive the lateral support plate 12 to make reciprocating linear motion in the lateral direction while the lateral support plate 12 moves longitudinally. Similarly, the vertical adjustment drive assembly can drive the vertical support plate 13 to make reciprocating linear motion in the vertical direction through the vertical drive arm 41.

[0053] The anti-tipping safety mechanism 5 includes a boom 51, a fixed chain 52, a lifting ring 53, and a hanging rope 54. The boom 51 is fixedly installed on the base 10. The upper end of the fixed chain 52 is fixedly connected to the top of the boom 51, and the lower end of the fixed chain 52 is fixedly connected to the lifting ring 53. Two hanging ropes 54 are provided and pass through the lifting ring 53. The two hanging ropes 54 are arranged crosswise, and the two ends of the hanging ropes 54 are respectively used to connect to two lifting rings diagonally distributed on the top of the electrical cabinet 7.

[0054] In this invention, the hanging rope 54 is in a loose state during the testing operation, so it will not interfere with the seismic performance testing of the electrical cabinet 7. When the electrical cabinet 7 tilts, the two hanging ropes 54 work together to hold the top of the electrical cabinet 7, preventing the electrical cabinet 7 from falling directly to the ground. In addition, the hanging ropes 54 are evenly stressed and are not easy to break.

[0055] In some embodiments, such as Figures 1-7 As shown, in a preferred embodiment of the present invention, a testing method for an electrical cabinet seismic testing device includes the following steps:

[0056] Step 1: Install and fix the electrical cabinet 7 on the loading plate 14, connect the lifting ring on the top of the electrical cabinet 7 to the hanging rope 54, and install displacement gauges and accelerometers on the four sides and the top of the electrical cabinet 7 at the set intervals.

[0057] Step 2: The vertical support plate 13 and the horizontal support plate 12 are fixed relative to each other by locking component 6. The vertical sway control mechanism 2 and the horizontal sway control mechanism 3 are used to control the swaying of the vertical support plate 11 and the horizontal support plate 12 to simulate the combined vibration effect in the horizontal direction.

[0058] Step 3: Fix the longitudinal support plate 11 and the base 10, as well as the transverse support plate 12 and the longitudinal support plate 11, relative to each other by locking component 6. Connect the vertical drive arm 41 to the lower end of the vertical support plate 13. Control the vertical support plate 13 to shake by the vertical rocking control mechanism 4 to simulate the vertical vibration effect.

[0059] Step 4: Record the readings of the displacement gauge and accelerometer;

[0060] Step 5: Configure various test specimens in different modes inside electrical cabinet 7. Repeat steps 2 to 4 after each configuration to test the seismic performance of electrical cabinet 7 under different loads and different load distributions.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
