Technical Field

[0002] The high-voltage box is a key component in the energy storage system, primarily responsible for the distribution, management, and protection of electrical energy. Due to the diversification of needs, the electrical components within the high-voltage box are also diverse. Under the new standards, in order to ensure the safe and stable operation of the energy storage system, the structural safety and vibration issues of the high-voltage box have become particularly important. The high-voltage box vibration test fixture is mainly used to test the performance and reliability of the high-voltage box in a vibration environment to ensure the performance and reliability of the high-voltage box in the actual working environment. The high-voltage box vibration test fixture includes a limit device. The main function of the limit device is to ensure that the high-voltage box under test remains fixed and stable during the vibration test, thereby ensuring the accuracy of the test results and the safety of the high-voltage box.

[0003] The limiting device of the traditional high-voltage box vibration test tooling is usually limited by sheet metal bending.

The shape after sheet metal bending is fixed. Therefore, the limiting device of the above-mentioned traditional high-voltage box vibration test tooling can only be adapted to high-voltage boxes of a specific size. Utility Model Content

DETAILED DESCRIPTION

[0036] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present invention.

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the embodiments of the present application.

[0038] In addition, it should be noted that in the description of the embodiments of this application, unless otherwise clearly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0039] A high-voltage box is an enclosed structure used to house and protect high-voltage electrical equipment. It is mainly used to ensure the safe operation of the high-voltage equipment inside it, prevent the external environment from affecting the high-voltage equipment, and provide the necessary operation and maintenance space. The high-voltage box vibration test fixture is a special equipment used to test the performance and reliability of high-voltage equipment (such as transformers, high-voltage switchgear, etc.) under different vibration conditions. The high-voltage box vibration test fixture is used to fix the high-voltage box on a vibration table for vibration testing. The vibration test can simulate the vibration stress in the actual working environment, help discover potential mechanical problems and structural defects, and improve the reliability and life of the high-voltage equipment. In the high-voltage box vibration test fixture, the limit device is a key component used to ensure that the position and range of motion of the high-voltage box are controlled during the test to prevent excessive vibration or displacement from causing damage to the high-voltage equipment. At the same time, by controlling the range of motion of the high-voltage box, the limit device can also ensure the consistency of the test conditions and improve the reliability and accuracy of the test results.

[0040] When installing the high-voltage box vibration test tooling on the vibration table, the limit device is usually installed using the installation positions with fixed intervals set on the vibration table. For the limit device formed by sheet metal bending, it is limited by the installation position of the vibration table and the size of the limit device itself. The limit device can only limit the high-voltage box of a specific size. For high-voltage boxes of different shapes and sizes, it may be necessary to re-make the sheet metal bending limit device, which has poor compatibility.

[0041] In response to the above problems, the embodiments of the present application provide a limit device and a vibration test tool. In the device, an adjustment hole is designed on the bottom plate. The position and shape of the adjustment hole can effectively adjust the installation position of the limit device on the vibration table. At the same time, with the side limit assembly, the width and length directions of high-voltage boxes of different widths and lengths can be limited. The support frame is designed with multiple installation positions. The upper limit assembly can select an installation position for connection according to high-voltage boxes of different heights, and the fine-tuning assembly included in the upper limit assembly can further fine-tune the height of the upper limit assembly, that is, further fine-tune based on different installation heights. The device can accurately limit high-voltage boxes of different heights, widths and lengths, thereby improving compatibility.

[0042] The embodiments of the present application are described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figures 1 to 3 The embodiment of the present application provides a limiting device, comprising: a base plate 10, a support frame 20, a side limiting assembly 30 and an upper limiting assembly 40; the base plate 10 is used to be mounted on a vibration table; the support frame 20 is arranged on the base plate 10;

[0044] The side limit assembly 30 is connected to the support frame 20 and includes a first connecting member 301. The first connecting member 301 is used to adjust the distance between the side of the side limit assembly 30 away from the support frame 20 and the support frame 20.

[0045] The upper limit assembly 40 is connected to the support frame 20 through one of multiple installation positions on the support frame 20. The heights of the multiple installation positions are different. The upper limit assembly 40 includes a fine-tuning assembly 401, which is used to adjust the limit height of the upper limit assembly 40.

[0046] When limiting the position of the high-voltage box, the installation position of the base plate 10 on the vibration table is selected based on the placement of the high-voltage box on the vibration table. The support frame 20 is fixed to the base plate 10 in various ways, such as welding and bolting. The embodiment of the present application does not limit the method of fixing the support frame 20 to the base plate 10.

[0047] The support frame 20 is provided with one or more rows of holes along the height direction. The multiple rows of holes are aligned in the horizontal direction and can be regarded as multiple rows of holes. Each row of holes can have one or more holes. The heights of the multiple rows of holes are different. Except for the row of holes closest to the bottom plate 10, the remaining rows of holes in the support frame 20 correspond to multiple installation positions on the support frame 20. For example, see Figure 1 The support frame 20 is provided with multiple rows of holes, each row contains two holes. Except for the row of holes closest to the base plate 10, the other multiple rows of holes in the support frame 20 correspond to multiple installation positions of the support frame 20, and each row corresponds to one installation position.

[0048] The side limit assembly 30 is connected to the support frame 20 through the first connecting member 301, and the connection position is the row or rows of holes closest to the bottom plate 10. One side of the side limit assembly 30 is close to the support frame 20 for connecting to the support frame 20; the other side is away from the support frame 20 for contacting the high-voltage box. In the embodiment of the present application, two or more limit devices can be arranged opposite to each other on both sides of the high-voltage box, so that by operating the first connecting member 301 of the side limit assembly 30, the distance from the side away from the support frame 20 to the support frame 20 can be adjusted, thereby adjusting the limit distance of the side limit assembly 30, that is, adjusting the limit distance between the relatively arranged limit devices. For example, see Figure 1 If the width or length of the high-voltage box is relatively small, operate the first connecting member 301 so that the side limit assembly 30 is away from the support frame 20 and away from the support frame 20; if the width or length of the high-voltage box is relatively large, operate the first connecting member 301 so that the side limit assembly 30 is away from the support frame 20 and close to the support frame 20.

[0049] According to the height of different high-voltage boxes, one of the installation positions at different heights on the support frame 20 is selected. The upper limit assembly 40 and the support frame 20 are connected through the installation position at a selected height. At the same time, the limit height of the upper limit assembly 40 can be further adjusted by the fine-tuning assembly 401 included in the upper limit assembly 40.

[0050] In the limit device of the present embodiment, the side limit assembly 30 is used to adjust the limit distance, achieving compatibility with the width or length of the high-voltage box. A mounting position that matches the height of the high-voltage box is selected on the support frame 20, and the upper limit assembly 40 is connected to the support frame 20 at a mounting position that matches the height of the high-voltage box. Furthermore, the fine adjustment assembly 401 of the upper limit assembly 40 further adjusts the limit height, achieving compatibility with the high-voltage box's height. This device can flexibly and conveniently limit high-voltage boxes of different heights, widths, or lengths, thereby improving the compatibility of the limit device.

[0051] In addition, if a sheet metal bending limit device is damaged, it may need to be replaced as a whole or undergo complicated repair operations. However, the replacement or repair of each part of the limit device in the embodiment of the present application is relatively simple.

[0052] In one implementation, the support frame 20 has a first mounting hole 201, and there are one or more first mounting holes 201. The side limit assembly 30 also includes a side limit plate 302, and the side limit plate 302 is connected to the first connecting member 301, and the first connecting member 301 is connected to the support frame 20 through the first mounting hole 201.

[0053] For example, the row or rows of holes on the support frame 20 closest to the bottom plate 10 are the first mounting holes 201. Figure 1 The row of holes closest to the bottom plate 10 is the first mounting holes 201 .

[0054] The side limit assembly 30 includes a first connecting member 301 and a side limit plate 302. Optionally, the side limit plate 302 is provided with a groove that matches the first connecting member 301, through which the side limit plate 302 and the first connecting member 301 can be clamped. The first connecting member 301 is connected to the support frame 20 through the first mounting hole 201, thereby achieving the connection between the entire side limit assembly 30 and the support frame 20. For example, see Figure 1 and Figure 2 The side limit assembly 30 and the support frame 20 are connected at the first mounting hole 201 through the first connecting member 301 , and the side limit piece 302 is connected through the first connecting member 301 and the groove on the side limit piece 302 .

[0055] In one implementation, a nut is welded to the outside of the first mounting hole 201 , and the first connecting member 301 includes a screw.

[0056] The first mounting hole 201 is welded with one or more nuts outside, and the screw rod included in the first connecting piece 301 can be a screw rod with a head or a screw rod without a head. If the screw rod included in the first connecting piece 301 is a screw rod with a head, the end of the screw rod with the head is installed on the side of the first mounting hole 201 away from the side limiting piece 302, a nut is welded on the side of the first mounting hole 201 close to the side limiting piece 302, and the end of the screw rod without the head is clamped with the groove of the side limiting piece 302. If the screw rod included in the first connecting piece 301 is a screw rod without a head, a nut is welded on either side of the first mounting hole 201, or a nut is welded on each side of the first mounting hole 201, and one section of the screw rod is clamped with the groove of the side limiting piece 302.

[0057] In addition, in order to improve the reliability and stability of the connection between the screw rod and the nut, a gasket can be used between the nut and the screw rod to increase the friction of the bolt connection, thereby effectively preventing the nut from loosening.

[0058] In the limiting device of the embodiment, the distance between the side limiting piece 302 and the support frame 20 can be adjusted by rotating the screw rod of the first connecting piece 301, and then the limiting distance of the side limiting assembly 30 is adjusted. For example, if the width or length of the high-voltage box is relatively small, the screw rod is rotated in the first direction, so that the side of the side limiting assembly 30 away from the support frame 20 is away from the support frame 20; if the width or length of the high-voltage box is relatively large, the screw rod is rotated in the second direction, so that the side of the side limiting assembly 30 away from the support frame 20 is close to the support frame 20, and the second direction is the opposite direction of the first direction.

[0059] In the embodiment, the side limiting assembly 30 exerts pressure on the side of the high-voltage box, and since the cross-sectional area of the screw rod is small, the screw rod is easy to damage the high-voltage box when exerting limiting force on the side of the high-voltage box. By arranging the side limiting piece 302, the stress area of the high-voltage box can be increased, so that the side limiting assembly 30 can not only be compatible with the limiting distance of the high-voltage box, but also ensure the safety of the high-voltage box during the test process.

[0060] In one implementation, the support frame 20 has a second mounting hole 202, and the second mounting hole 202 has multiple second mounting holes 202 arranged in one or more columns in the height direction, and the multiple columns of second mounting holes 202 are aligned in the horizontal direction, and different heights of the second mounting holes 202 correspond to multiple mounting positions.

[0061] For example, the row or rows of holes in the support frame 20 that are closest to the base plate 10 are the first mounting holes 201, and the other rows of holes in the support frame 20 except the first mounting holes 201 are the second mounting holes 202. The multiple rows of holes of the second mounting holes 202 can be arranged equidistantly in the height direction, or can be set to non-equidistant arrangement as required. The multiple rows of holes of different heights correspond to multiple installation positions, that is, each row of holes has a different height, and each row of holes corresponds to an installation position.

[0062] For example, refer to Figure 1 and Figure 3 Each row of the second mounting holes 202 includes two holes, and the multiple rows of holes are arranged equidistantly in the height direction. Each row of holes corresponds to an installation position, that is, one installation position includes two holes in a row.

[0063] In one implementation, the upper limit assembly 40 further includes: an upper limit bracket 402 and an upper limit plate 403;

[0064] The upper limit bracket 402 is connected to the support frame 20 through the second mounting hole 202 . The upper limit plate 403 is disposed on the upper limit bracket 402 . The fine-tuning component 401 is disposed on a side of the upper limit plate 403 close to the base plate 10 .

[0065] In addition to the fine-tuning assembly 401, the upper limit assembly 40 also includes an upper limit bracket 402 and an upper limit plate 403. Depending on the height of the high-voltage box, one of the multiple mounting positions at different heights for the second mounting hole 202 on the support frame 20 can be selected, thereby installing the upper limit bracket 402 at the corresponding mounting position on the support frame 20. The upper limit plate 403 is positioned above the upper limit bracket 402 and bolts are used to connect the upper limit bracket 402 and the upper limit plate 403. The fine-tuning assembly 401 is positioned on the side of the upper limit plate 403 near the base plate 10 to further adjust the limit height of the limit assembly 30.

[0066] In one implementation, the fine-tuning assembly 401 includes: an upper limit gasket 4011 and / or a movable pressure plate 4012;

[0067] One or more upper limit gaskets 4011 may be provided between the upper limit plate 403 and the upper limit bracket 402 , and a movable pressing plate 4012 is provided at one end of the upper limit plate 403 away from the upper limit bracket 402 .

[0068] Upper limit gaskets 4011 are installed between the upper limit plate 403 and the upper limit bracket 402. By adjusting the number of upper limit gaskets 4011, the upper limit height of the upper limit assembly 40 can be further adjusted after the upper limit bracket 402 is positioned. For example, after the upper limit bracket 402 is positioned, the number of upper limit gaskets 4011 can be adjusted based on the distance between the upper limit plate 403 and the top of the high-voltage box. The thickness of the upper limit gaskets 4011 can be customized according to actual needs, for example, the thickness of the upper limit gaskets 4011 is 2 mm.

[0069] The movable pressure plate 4012 is installed at one end of the upper limit plate 403 away from the upper limit bracket 402. The movable pressure plate is movable and the limit height of the upper limit assembly 40 can be adjusted by adjusting the distance between the movable pressure plate 4012 and the upper limit plate 403.

[0070] In one implementation, the movable pressure plate 4012 is connected to the upper limit plate 403 via a second connecting member 404 . The second connecting member 404 includes a bolt and a nut. The bolt is engaged with the movable pressure plate 4012 .

[0071] The upper limit assembly 40 also includes a second connecting member 404, which includes a bolt and a nut. The end of the bolt without a head is positioned on the side of the upper limit plate 403 away from the base plate 10 for rotational fixation with the nut. The movable pressure plate 4012 is provided with a slot that matches the other end of the bolt for secure connection with the bolt.

[0072] In the limiting device of the embodiment of the present application, the height of the movable pressure plate 4012 can be adjusted by rotating the bolts. In this case, the limiting height of the limiting device is the limiting height of the movable pressure plate 4012. The second connecting member 404 applies pressure to the top of the high-voltage box via the bolts. The movable pressure plate 4012 can increase the contact area between the pressure and the high-voltage box, ensuring the safety of the high-voltage box during testing.

[0073] In the case that the fine-tuning assembly 401 includes both the upper limit gasket 4011 and the movable pressing plate 4012 , after adjusting the limit height through the upper limit gasket 4011 , further adjustment can be performed through the movable pressing plate 4012 .

[0074] In this embodiment of the present application, one of the multiple installation positions at different heights for the second installation hole 202 on the support frame 20 can be selected according to the height of the high-voltage box to install the upper limit bracket 402 on the support frame 20. Furthermore, the limit height of the upper limit assembly 40 can be further adjusted by adjusting the number of upper limit spacers 4011 and the height of the movable pressure plate 4012. Furthermore, the movable pressure plate 4012 can also ensure the safety of the high-voltage box during testing.

[0075] In one implementation, an adjustment hole 101 is provided on the base plate 10 , and the base plate 10 is fixed to the vibration table through the adjustment hole 101 . The adjustment direction of the adjustment hole 101 is along the limiting direction of the side limiting assembly 30 .

[0076] The adjustment hole 101 can be a waist-shaped hole. The waist-shaped hole is usually elliptical or oblong. Compared with a standard circle, its long axis is longer, which can provide a certain range of sliding adjustment space. A full-threaded long bolt that matches the hole diameter of the waist-shaped hole is used. The full-threaded long bolt can slide in the waist-shaped hole. According to the placement position of the high-voltage box, the base plate 10 is placed in a suitable position, and the full-threaded long bolt is slid along the limiting direction of the side limiting assembly 30 to the appropriate position in the waist-shaped hole. The nut is tightened, and the base plate 10 is installed at a certain installation position of the vibration table through the full-threaded long bolt and the waist-shaped hole, thereby limiting the position of the high-voltage box on the vibration table.

[0077] Reference Figures 4 to 7 The present invention provides a vibration test fixture comprising a plurality of the position limiting devices described in the above embodiments, wherein some of the position limiting devices are disposed on opposite sides of a device to be vibration tested. Optionally, the device to be vibration tested is a high-voltage box.

[0078] When limiting the position of the high-voltage box, multiple limiting devices in the above embodiments can be used to limit the position of the high-voltage box. One or more limiting devices in the above embodiments can be installed on both sides of the high-voltage box to limit the width, length and height of the high-voltage box.

[0079] In the embodiment of the present application, the high-voltage box is fixed on the vibration table by a vibration test tool, and the height compatibility design and width and length compatibility design of the limit device can flexibly be compatible with the tested high-voltage boxes of different heights, widths and lengths, thereby improving compatibility.

[0080] In addition, the compatibility design of the limit device also takes into account the ease of installation. Through standard hole positions and limit plates, even non-professionals can quickly understand and execute the installation process, reducing installation time and potential errors. When designing compatibility, it also ensures the safety and reliability of the high-voltage box during testing.

[0081] In one implementation, the vibration test fixture further includes: one or more limiting base plates 50 , the limiting base plates 50 and another part of the limiting devices among the plurality of limiting devices, which are relatively arranged on two sides of the device to be vibration tested.

[0082] For example, if the device to be vibration tested is incompletely packaged, one or more limiting base plates 50 can be used on one side of the incomplete package, and one or more limiting devices in the above embodiments can be used on the opposite side of the incomplete package to limit the package.

[0083] For example, refer to Figures 4 to 7 Because the high-voltage box has an incompletely enclosed side, two limiting base plates 50 are installed on this incompletely enclosed side of the high-voltage box, and two limiting devices from the above embodiment are installed on the side opposite to this incompletely enclosed side of the high-voltage box. This allows the limiting of the incompletely enclosed side of the high-voltage box and its opposite side. At the same time, the two limiting devices installed on the opposite sides can use the side limiting assembly 30 to fine-tune the limiting distance, and the upper limiting assembly 40 to adjust the limiting height. The limiting devices from the above embodiment are installed on the other two opposite sides to achieve limiting of the other two opposite sides, as well as fine-tune the limiting distance and adjust the limiting height. Optionally, the limiting base plate 50 can have the same structure as the base plate 10 in the limiting device.

[0084] After considering the specification and practicing the technical solutions disclosed herein, those skilled in the art will easily come up with other implementation plans of the embodiments of the present application.

[0085] The embodiments of the present application are intended to cover any variations, uses or adaptive changes of the embodiments of the present application, which follow the general principles of the embodiments of the present application and include common knowledge or customary technical means in the technical field that are not disclosed in the embodiments of the present application.

[0086] It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the present invention being indicated by the following claims.

[0087] It should be understood that the embodiments of the present application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the embodiments of the present application is limited only by the appended claims.
