Description

Technical Field

[0001] This utility model relates to the field of environmental and vibration testing equipment, specifically to a thermal insulation support assembly for comprehensive testing of specimens. Background Technology

[0002] In the fields of deep-sea oil and gas exploration and high-end equipment manufacturing, key equipment and structural components often need to operate under multiple extreme coupled environments, such as high temperature, high pressure, and vibration. To ensure their reliability, they must be verified through environmental tests simulating these harsh operating conditions. A comprehensive testing system combining a vibration test bench and an environmental simulation chamber is crucial equipment for conducting such tests.

[0003] However, in the practical application of such integrated testing systems, a long-standing technical challenge lies in the connection and isolation structure between the vibration table and the high-temperature environment simulation chamber. The vibration table itself is a precision device, and its core components, such as motors, magnetic circuits, and sensors, are extremely sensitive to high-temperature environments, with strictly limited operating temperature ranges. It cannot be exposed to the high-temperature conditions inside the environmental chamber for extended periods. Therefore, a dedicated structure is necessary between the vibration table and the specimen, capable of reliably mounting the specimen and transmitting vibration excitation while effectively preventing heat transfer from the environmental chamber to the vibration table itself.

[0004] Currently, common connection and support structures struggle to simultaneously meet the requirements of efficient thermal insulation and reliable mechanical performance. If thermal insulation is prioritized, the mechanical strength and stiffness are often insufficient, making it difficult to guarantee the accuracy of vibration transmission and the reliability of installation connections. Conversely, if mechanical support is prioritized, rigid connections can create significant thermal bridging effects, failing to effectively isolate heat conduction. This leads to increased vibration table temperature, affecting its normal operation and even causing equipment damage. This contradiction severely restricts the effectiveness and safety of high-temperature vibration testing.

[0005] Therefore, developing a new type of support and isolation structure that can effectively resolve the contradiction between vibration transmission and high-temperature isolation has become an urgent technical requirement for improving comprehensive environmental testing capabilities and ensuring the safety of testing equipment and the accuracy of data.

[0010] In a further technical solution, the water-cooling adapter is cylindrical, and the bottom plate of the environmental simulation box has clearance holes corresponding to the water-cooling adapter.

[0011] To achieve the above objectives, another technical solution adopted by this utility model is: A thermal insulation support assembly for comprehensive testing of specimens is applied in a comprehensive testing system, the system including a vibration test bench and an environmental simulation chamber; The environmental simulation chamber is sealed on the vibration test bench, forming a closed environmental simulation cavity; the length of the environmental simulation cavity is greater than the length of the specimen positioned on the vibration test bench. The vibration test bench is equipped with a thermal insulation support assembly for positioning and supporting the specimen. The thermal insulation support assembly is sealed and thermally insulated from the bottom plate of the environmental simulation chamber. The thermal insulation support assembly includes a water-cooled adapter, an additional platform, and a flexible thermal insulation structure connected sequentially from bottom to top.

[0019] The working principle and advantages of this utility model are as follows: This utility model discloses a thermal insulation support assembly for comprehensive testing of specimens. On the one hand, it supports the specimens, and on the other hand, it isolates the environment inside the environmental simulation cavity to avoid adverse effects of environmental factors on the vibration test bench.

[0020] The thermal insulation support assembly includes a water-cooled adapter, a flexible thermal insulation structure, and a thermal insulation cover. Through the combined design of these three components, it achieves the following technical effects under combined vibration and environmental testing modes: The thermal insulation cover is designed for testing temperatures (especially extreme temperatures) inside the environmental simulation chamber. Through its thermal insulation properties, it blocks most of the heat from entering, significantly reducing the temperature load transferred to the supporting structure below.

[0021] The water-cooled adapter addresses the residual heat from the insulation cover and the heat generated by the vibration table itself. It actively removes heat via external circulating water, ensuring the moving coil of the vibration table remains within a safe temperature range. This not only prevents equipment damage due to overheating but also ensures the temperature field within the environmental simulation chamber is unaffected by the table's temperature, thereby improving the accuracy of the test data.

[0022] The flexible thermal insulation structure, as a key component connecting the two, not only achieves a reliable seal at the bottom of the environmental simulation chamber, ensuring the stability of the temperature and humidity environment, but its flexibility also ensures that the mechanical vibrations generated by the vibration table can be transmitted to the specimen with almost no loss. This perfect balance between the contradiction between "static sealing" and "dynamic vibration" is a prerequisite for the effective operation of the other two components. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0026] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0027] See appendix Figures 1-3 As shown, this embodiment discloses a thermal insulation support assembly for comprehensive testing of specimens, which is applied to a comprehensive testing system. The system includes a vibration test bench 3 set on a horizontal base 1, and an environmental simulation chamber 2 combined above the vibration test bench 3. The interior of the environmental simulation chamber is a sealed environmental simulation cavity 21, the length of which is greater than the length of the specimen 4 positioned above the vibration test bench 3.

[0028] like Figures 3-5 As shown, the vibration test bench 3 is equipped with a thermal insulation support assembly 6 for positioning and supporting the specimen 4. The thermal insulation support assembly 6 is sealed and thermally insulated from the bottom plate 26 of the environmental simulation chamber 2.

[0029] The thermal insulation support assembly 6 includes cylindrical water-cooled adapters 62 connected sequentially from bottom to top (see...). Figure 6 ), tooling fixtures 60 (see) Figure 7 Its length corresponds to the length of specimen 4), flexible thermal insulation structure 63, and multiple clamps 64 (see Figure 9 In this embodiment, each clamp 64 is equidistantly spaced along the length of the tooling fixture 60 to clamp the specimen 4 of a certain length.

[0030] The cylindrical water-cooled adapter 62 is fixed to the moving coil 31 of the platform.

[0031] Also includes clamp insulation cover 65a (see Figure 8 The heat insulation cover 65a is installed around the tooling fixture 60, and is sealed and fixed to the upper surface of the base plate 26 below. It is sealed and fitted with the flexible heat insulation structure 63 above. The heat insulation cover 65a is used to isolate the temperature (such as high temperature) in the environmental simulation chamber 2 to avoid adverse effects on the tooling fixture 60.

[0032] The flexible thermal insulation structure 63 includes a thermal insulation plate 631 and a thermal insulation film 632 positioned on the thermal insulation plate 631. Figure 4 , Figure 5 As shown, the insulation plate 631 is fixed to the top of the tooling fixture 60, and the outer edge of the insulation film 632 is positioned at the upper part of the fixture insulation cover 65a. This design can achieve both thermal insulation and sealing of the gap between the insulation plate 631 and the fixture insulation cover 65a, and flexible connection between the insulation plate 631 and the fixture insulation cover 65a.

[0033] like Figures 10-12 As shown, in another embodiment, the thermal insulation support assembly 6 includes cylindrical water-cooled adapters 62 connected sequentially from bottom to top (see...). Figure 6 Additional countertop 66 (see) Figure 13 The additional platform 66 is used to place the small specimen 4.

[0034] The cylindrical water-cooled adapter 62 is fixed to the moving coil 31 of the platform.

[0035] Also includes countertop thermal insulation cover 65b (see Figure 14 The additional platform 65b is installed around the periphery of the additional platform 66, and is sealed and fixed to the upper surface of the base plate 26 below, and is sealed and fitted with the flexible thermal insulation structure 63 above. The platform thermal insulation cover 65b is used to isolate the temperature (such as high temperature) in the environmental simulation chamber 2 to avoid adverse effects on the additional platform 66.

[0036] The flexible thermal insulation structure 63 includes a thermal insulation plate 631 and a thermal insulation film 632 positioned on the thermal insulation plate 631. Figure 11 , Figure 12 As shown, the insulation plate 631 is fixed to the top of the additional tabletop 66, and the outer edge of the insulation film 632 is positioned on the upper part of the tabletop insulation cover 65b. This design can achieve both thermal insulation and sealing of the gap between the insulation plate 631 and the tabletop insulation cover 65b, and flexible connection between the insulation plate 631 and the tabletop insulation cover 65b.

[0037] Preferably, in the two embodiments described above, the heat insulation film 632 can be made of heat-resistant silicone rubber, which is a material of existing technology and will not be described in detail here.

[0038] Preferably, in the two embodiments described above, an inlet and an outlet may be provided on the side of the water-cooled adapter 62, and a water flow channel (not shown in the figure) is provided inside for cooling the water-cooled adapter.

[0039] In practice, the temperature and flow rate of the circulating water can be adjusted according to design requirements or the real-time detected temperature at the bottom of the water-cooled adapter 62. During operation, the water-cooled adapter 62 is connected to the external circulating water. Both the temperature inside the upper environmental simulation chamber 21 and the temperature of the moving coil 31 of the lower vibration test bench 3 can be carried away by the external circulating water through the water-cooled adapter 62. This prevents temperature from being transferred to the moving coil 31 during high-temperature testing, thus avoiding overheating of the vibration test bench 3 and potential malfunctions or damage. It also ensures that the temperature inside the environmental simulation chamber 21 is not affected by the temperature of the moving coil 31.

[0040] The environmental simulation chamber 2 has a clearance hole 27 on its bottom plate 26 corresponding to the thermal insulation support assembly. The bottom plate 26 is made of a pressure-bearing plate with an insulation layer, providing thermal insulation, pressure resistance, and load-bearing capacity. The diameter of the clearance hole 27 on the bottom plate 26 can be flexibly configured according to requirements. In some embodiments, the bottom plate 26 can be designed to be detachable from the bottom of the chamber.

[0041] Preferably, a heating device (such as a heating wire) can be directly installed inside the environmental simulation chamber 2 of the present invention. Since the heating device is relatively conventional and its installation location does not have special requirements, it is not shown in the diagram of the chamber. In addition, besides high-temperature testing, the environmental tests of the present invention can also simulate other environmental tests such as low temperature and humidity by setting up other corresponding equipment. Therefore, the present invention is not limited to the type of environmental test.

[0042] In summary, the design of the thermal insulation support component brings the following synergistic value: 1. Comprehensive protection: From high-temperature source isolation to heat dissipation through conduction paths and temperature control of core components, a multi-layered and three-dimensional temperature protection system is formed.

[0043] 2. Ensuring test accuracy: It not only protects the equipment but also ensures the purity of the vibration excitation and the stability of the temperature field, laying a solid foundation for obtaining true and reliable test data.

[0044] 3. Improve system reliability: Through division of labor and cooperation, the adverse effects of high temperature environment on precision vibration table are minimized, which greatly enhances the robustness and service life of the entire composite test system.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
