[0002] A rotating machinery life test platform is a comprehensive test device used to evaluate the service life and reliability of rotating machinery under various working conditions. By monitoring and analyzing the collected data, it studies the failure patterns of equipment components such as wear and fatigue, providing a scientific basis for the design optimization, performance improvement, maintenance strategy formulation and quality control of rotating machinery, and ensuring that the equipment has good reliability and a long service life in actual use. The base of the rotating machinery life test platform is the basic support structure of the entire test platform, which plays a key role in ensuring the smooth conduct of the test and the accuracy of the results. The base isolation and noise reduction structure of the rotating machinery life test platform is a structure designed to reduce the transmission of mechanical vibration and the spread of noise during the test. Most base isolation and noise reduction structures for rotating machinery life test platforms consist of simple sound insulation panels surrounding the base. These panels isolate and reduce noise, but ordinary sound insulation panels are planar structures that can only reflect noise in a simple straight line, making it difficult to dissipate a large amount of sound energy. As a result, their noise reduction effect is very limited. Therefore, this paper proposes a base isolation and noise reduction structure for rotating machinery life test platforms to address the above problems. Utility Model Content

[0016] Please see Figures 1-8 This utility model provides a technical solution: A base isolation and noise reduction structure for a rotating machinery life test platform includes a base plate 1, a top plate 2, and a base 3. An isolation component 4 is provided on the outer side of the base plate 1 and the top plate 2, and a noise reduction component 5 is provided on the inner side of the isolation component 4. An installation component 6 is provided between the isolation component 4 and the base plate 1 and the top plate 2. The noise reduction component 5 includes multiple sets of noise reduction strips 51, all of which are hollow inside and arranged in a regular, continuous, undulating wave shape. The multiple sets of noise reduction strips 51 are arranged perpendicularly to each other and are staggered. The inner cavity of the noise reduction strips 51 is filled with sound insulation cotton 52. The upper and lower ends of the base 3 are fixedly connected to the top plate 2 and the base plate 1, respectively.

[0017] As a further implementation of this solution, the isolation component 4 includes a pair of isolation support plates 41. The outer side of the noise reduction strip 51 is fixedly bonded to the inner side of the isolation support plate 41. The pair of isolation support plates 41 are rotatably connected by a hinge shaft. The above arrangement allows the pair of isolation support plates 41 to have folding and storage capabilities through the hinge shaft, thus improving space utilization when not in use.

[0018] As a further implementation of this solution, magnetic grooves 42 are provided on the outer edges of the two isolation support plates 41, and matching magnetic frames 43 are embedded in the two magnetic grooves 42. The two magnetic frames 43 are set with opposite magnetic poles. The above arrangement can provide magnetic attraction for the two isolation support plates 41 in the folded state to ensure the stability of the folded state.

[0019] As a further implementation of this solution, the installation component 6 includes positioning blocks 61 that are symmetrically and fixedly connected to the bottom inner side of the isolation support plate 41. The outer side of the base plate 1 is provided with positioning grooves 62. The positioning blocks 61 and positioning grooves 62 are equal in number, corresponding in position and matching in specifications. The above arrangement can provide good positioning capability for the installation of the isolation support plate 41, making its installation smoother.

[0020] As a further implementation of this solution, the installation component 6 also includes movable grooves 63 symmetrically opened at the top of the inner cavity of the isolation support plate 41. A return spring 64 is fixedly connected to the bottom of the movable groove 63. A movable support plate 65 that is longitudinally slidably connected to the inner wall of the movable groove 63 is fixedly connected to the top of the return spring 64. A limiting rod 66 is fixedly connected to the top center of the movable support plate 65. The limiting rod 66 passes through the top of the isolation support plate 41 and extends outward. Multiple limiting slots 67 are opened at the top edge of the top plate 2. The limiting slots 67 and the limiting rods 66 are equal in number, corresponding in position, and matched in specifications. The above arrangement can provide good installation capability between the isolation support plate 41 and the bottom plate 1 and the top plate 2, making the disassembly and assembly of the isolation support plate 41 easier.

[0021] Workflow: The base plate 1, top plate 2, and base 3 provide a solid foundation for the rotating machinery life test platform, playing a crucial role in ensuring the smooth conduct of the test and the accuracy of the results. When isolating and reducing noise on the base 3, the isolation component 4 and its noise reduction component 5 must first be installed around the base plate 1 and top plate 2 using the installation component 6, thus forming an enclosed isolation structure for the base 3. During installation, first, the two isolation support plates 41 are fully extended using the hinge shaft. Then, the two isolation support plates 41 are moved close to the outer sides of the base and top plate 2, and the positioning block 61 is inserted into the positioning groove 62 on the outer side of the base plate 1 for positioning. Simultaneously, the limiting rod 66 is pulled upwards, so that the end of the limiting rod 66 is higher than the top plate. 2. When the positioning block 61 is fully inserted into the positioning slot 62, the inner side of the isolation support plate 41 will fit against the outer side of the bottom plate 1 and the top plate 2. At this time, the limiting rod 66 is released. Since the limiting rod 66 will stretch the return spring 64 through the movable support plate 65 in the movable slot 63 when it is pulled up, the stretching force of the return spring 64 will disappear when the limiting rod 66 is released. The return spring 64 will then drive the movable support plate 65 and the limiting rod 66 to return and move down through its own rebound force. The lowered limiting rod 66 will be inserted into the limiting slot 67 opened at the corresponding position on the top edge of the top plate 2. The limiting slot 67 will limit the limiting rod 66 to complete the installation. The principle is the same when disassembling. After the isolation support plate 41 is installed, the noise reduction component 5 will be located between the bottom plate 1 and the top plate 2, forming a noise reduction enclosure for the base 3. When the noise from the base 3 propagates and diffuses, it will come into contact with the noise reduction strip 51. Since the noise reduction strip 51 is a regular, continuous, undulating wave-shaped arrangement and is arranged perpendicularly to each other, it can reflect and scatter sound waves multiple times to extend the propagation path of the sound waves and consume more sound energy, thereby providing excellent noise reduction effect. In addition, the structural design of the noise reduction strip 51 can enhance the bending and deformation resistance. When subjected to external impact or vibration, it can better disperse stress to reduce the risk of damage and extend the service life. Furthermore, the sound insulation cotton 52 filled inside can block the propagation of sound through its own mass and density. By relying on the density of the material, it reflects, absorbs, or blocks sound waves, making it difficult for sound to penetrate, thereby achieving the effect of sound insulation. When the isolation support plate 41 is not in use, it can be folded and stored to improve space utilization and make it more convenient to transport or store. When folding is required, the two isolation support plates 41 are first rotated and folded through the hinge shaft. After the outer sides of the two isolation support plates 41 are rotated and attached, the magnetic frame 43 embedded in the magnetic groove 42 will contact each other and magnetically attract each other. Finally, the stability of the folded state is ensured by magnetic attraction.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
