[0002] Power testing is a technique for measuring and analyzing power-related parameters in circuits or equipment. It has important applications in the performance testing of filter rod forming machines. By measuring power, we can understand the operating efficiency of electrical equipment such as motors, power supplies, and frequency converters in filter rod forming machines, determine whether they are working normally within the rated power range, and help evaluate equipment performance and detect potential faults in a timely manner.

[0003] While the filter rod forming machine is in operation, power testing is performed on individual electrical devices inside it. However, other operating electrical devices can cause electromagnetic interference to the tested electrical devices, affecting the test results.

[0004] However, when the filter rod forming machine is working, the internal electrical equipment operates in a vibrating environment due to the engine running. If the power of a single internal electrical device is tested when the filter rod forming machine is powered off, it is impossible to make the tested electrical device vibrate, and the authenticity of the test results cannot be guaranteed.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 6 As shown in the figure, this embodiment provides a power electronic power detection device, including a workbench 1, a vibration assembly 2, a clamping member 3, a power sensor 4, and a power supply. The workbench 1 includes a receiving space 11, and the vibration assembly 2 is placed within the receiving space 11. The vibration assembly 2 includes a fixed plate 21, multiple first elastic elements 22, a support plate 23, and a rotating member 24. The fixed plate 21 is fixedly placed in the receiving space 11 and has a clearance space. The multiple first elastic elements 22 are placed on the upper surface of the fixed plate 21, and the support plate 23 is fixedly placed on the multiple first elastic elements 22. The rotating member 24 is fixedly placed in the receiving space 11 and located below the fixed plate 21. The rotating member 24 includes a paddle assembly 241, which includes at least one paddle 2411. When the rotating member 24 operates, it can drive the paddle 2411 to reciprocate through the clearance space to paddle the support plate 23. Since the support plate 23 is connected to the multiple first elastic elements 22, the support plate 23 vibrates when it is paddled. The clamping member 3 is placed on the support plate 23 and is configured to clamp the filter rod forming machine. Therefore, when the support plate 23 vibrates, it will cause the filter rod forming machine to vibrate. The power sensor 4 is placed on the side wall of the accommodating space 11 and above the support plate 23. The power supply is configured to supply power to the electrical equipment, and the power sensor 4 is configured to detect the operating power of the supplied electrical equipment.

[0038] The power electronic power detection device provided in this embodiment provides an clearance space on a fixed plate 21 and multiple first elastic elements 22 on the upper surface of the fixed plate 21. A bearing plate 23 is placed on the multiple first elastic elements 22, and a rotating element 24 is placed below the bearing plate 23. When the rotating element 24 rotates, it drives the paddle 2411 to rotate. During the rotation, the paddle 2411 passes through the clearance space and repeatedly paddles the bearing plate 23, causing the bearing plate 23 to vibrate. A clamping element 3 is placed on the bearing plate 23 to clamp the filter rod forming machine, so that when the bearing plate 23 vibrates, it drives the filter rod forming machine to vibrate. At the same time, a power sensor 4 is used to detect the power of the electrical equipment inside the filter rod forming machine. The filter rod forming machine vibrates when it is powered off, so that when the operator uses the power sensor 4 to detect the power of the electrical equipment, the electrical equipment being tested will not be subject to electromagnetic interference. At the same time, the power supply provides power to the electrical equipment to be tested, and the filter rod forming machine is in a vibrating state, so that the electrical equipment being tested is powered on while simulating the environmental state when the electrical equipment is working, thus ensuring the accuracy of the power detection results of the electrical equipment inside the filter rod forming machine.

[0039] For example, the rotating component 24 includes a drive motor 242 and a rotating shaft 243. The drive motor 242 is fixedly placed on the side wall of the accommodating space 11, and the rotating shaft 243 is connected to the output end of the drive motor 242. When the drive motor 242 runs, it drives the rotating shaft 243 to rotate. The paddle group 241 is placed on the rotating shaft 243, and the rotating shaft 243 drives the paddle group 241 to rotate, so that the paddles 2411 in the paddle group 241 reciprocate to paddle the bearing plate 23, causing the filter rod forming machine held by the clamping component 3 to vibrate. Further, the rotating component 24 includes multiple paddle groups 241, which are spaced apart along the length direction of the rotating shaft 243. When the drive motor 242 drives the rotating shaft 243 to rotate, the paddles 2411 in the multiple paddle groups 241 can paddle the bearing plate 23 at multiple points along the extension direction of the rotating shaft 243, so that the vibration area of ​​the bearing plate 23 is larger. Furthermore, the paddle assembly 241 includes multiple paddles 2411, which are spaced apart circumferentially along the rotating shaft 243. When the drive motor 242 drives the rotating shaft 243 to rotate, the multiple paddles 2411 sequentially paddle the support plate 23, so that the support plate 23 can vibrate continuously, thereby achieving a more realistic simulation of the environmental conditions when the electrical equipment is working.

[0040] In this embodiment, multiple rotating components 24 are provided, all of which are fixedly placed in the accommodating space 11 and are arranged at intervals along the first direction. This allows the multiple rotating components 24 to move the support plate 23 in all directions, making the vibration of the support plate 23 more balanced and more realistically simulating the environmental conditions during the operation of electrical equipment, thus making the detection results of the electrical equipment more accurate. Furthermore, the power electronic power detection device also includes multiple bearings 5. The sidewall of the accommodating space 11 has multiple mounting holes, each corresponding to a bearing 5. The end of the rotating shaft 243 of the multiple rotating components 24 away from the drive motor 242 is placed in the inner ring of the multiple bearings 5. This arrangement improves the smoothness of the rotation process of the multiple rotating shafts 243, allowing the paddles 2411 on the rotating shafts 243 to move the support plate 23 more smoothly, further improving the balance of the vibration of the support plate 23, and thus further improving the accuracy of the power detection results of the electrical equipment in the filter rod forming machine. In this embodiment, the bearings 5 ​​are partially exposed outside the mounting holes.

[0041] For example, four fixing plates 21 are provided, and the four fixing plates 21 are respectively located at the four corners of the receiving space 11. Each fixing plate 21 is provided with a first elastic element 22, and the bearing plate 23 is placed on the four first elastic elements 22. The four fixing plates 21 are correspondingly arranged at the four corners of the receiving space 11, which can expand the range of clearance space, make the area of ​​the multiple rotating parts 24 on the bearing plate 23 larger, and thus make the filter rod forming machine vibrate in all directions, thereby further improving the accuracy of electrical equipment testing results.

[0042] For example, the clamping component 3 includes a mounting plate 31, four second elastic members 32, and four clamping blocks 33. Four slots 311 are provided at the four corners of the mounting plate 31, and the four second elastic members 32 are respectively placed within the four slots 311. The four clamping blocks 33 are connected to the four second elastic members 32, and are used to clamp and fix the filter rod forming machine. The filter rod forming machine is placed on the mounting plate 31, and the four clamping blocks 33 clamp it from the four corners, reducing the risk of the filter rod forming machine falling when the support plate 23 vibrates. By providing the second elastic members 32, the position of the clamping blocks 33 can be changed, allowing the four clamping blocks 33 to clamp filter rod forming machines of different sizes. Furthermore, when the rotating component 24 moves and causes the support plate 23 to vibrate, the four clamping blocks 33 can maintain a close fit with the filter rod forming machine in real time, further reducing the risk of the filter rod forming machine falling. Meanwhile, the slot 311 on the mounting plate 31 can limit the swing range of the second elastic element 32, so that the four clamping blocks 33 can fit more tightly with the filter rod forming machine and clamp it, thereby improving the stability of the clamping parts 3 in clamping the filter rod forming machine.

[0043] The power electronic power detection device includes multiple clamping parts 3, which are placed at intervals on the support plate 23. This allows for the simultaneous detection of the operating power of electrical equipment in multiple filter rod forming machines, significantly improving the detection efficiency of the staff.

[0044] In this embodiment, the bottom surface of the support plate 23 is provided with strip grooves 231 at intervals. When the rotating component 24 is running, the paddle 2411 can repeatedly enter the strip grooves 231. The arrangement of the strip grooves 231 increases the frequency at which the paddle 2411 moves the support plate 23, thereby increasing the vibration frequency of the support plate 23. This makes the vibration frequency of the filter rod forming machine closer to the vibration frequency during operation, resulting in more accurate test results for the electrical equipment. Specifically, the bottom surface of the support plate 23 is provided with multiple strip grooves 231, and multiple rotating components 24 are correspondingly arranged below the multiple strip grooves 231, further increasing the vibration frequency of the support plate 23 and further improving the accuracy of the test results for the electrical equipment.

[0045] Furthermore, the end of the lever 2411 that contacts the support plate 23 has an arc-shaped structure, that is, the end of the lever 2411 away from the rotating shaft 243 has an arc-shaped structure. In this way, when the lever 2411 moves the support plate 23, the arc-shaped contact reduces scratches on the bottom surface of the support plate 23 and also reduces damage to the lever 2411 itself, thus extending the service life of the power electronic power detection device.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
