Description

Technical Field

[0001] This utility model relates to the field of seismic testing technology for nuclear power equipment, and more specifically, to a seismic testing device. Background Technology

[0002] The safe operation of nuclear power plants places extremely high demands on the seismic performance of equipment. Therefore, after the design of new nuclear power products is completed, their strength, stiffness, and seismic resistance must be verified through prototype testing. However, existing seismic testing facilities have strict size and weight limitations. If the size or weight of components such as hinges, transmissions, interlocks, locking mechanisms, and pressure balancing mechanisms to be tested exceeds the load-bearing capacity of the testing platform, the components must be disassembled and subjected to seismic tests multiple times. This disassembly testing method not only increases testing costs exponentially, but more importantly, it cannot effectively verify the seismic resistance of the connections between components, making it difficult to accurately reflect the overall seismic performance of the equipment under actual operating conditions. Furthermore, disassembly testing may lead to component position deviations due to multiple reassemblies, affecting the accuracy of the test results.

[0003] To address the aforementioned issues, a dedicated seismic testing device is urgently needed. This device must possess sufficient rigidity and strength to withstand the loads during seismic testing, while its own weight and volume must be compatible with the limitations of the test bench. Furthermore, it must be able to integrate and install all the mechanisms involved in the test, simulating their installation methods under actual operating conditions, ensuring that the total weight and dimensions after installation meet the requirements of the test bench. This will enable synchronous seismic testing of all mechanisms and connecting parts, guaranteeing the accuracy and safety of the test. Utility Model Content

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

[0025] like Figures 1 to 4 As shown, this utility model provides a seismic testing device, including a base plate 1, a vertical plate 2, an arc plate 3, a support plate 4, a support plate 5, a diagonal tie rod 6, and a stiffening plate 7; The upright plate 2 is vertically fixed to the upper surface of the base plate 1 by welding. The arc plate 3 is semi-circular, with one end fixedly connected to the top of the upright plate 2 and the other end fixedly connected to the upper surface of the base plate 1. The upright plate 2, the arc plate 3, and the base plate 1 together form a triangular frame structure. The support plate 5 is welded and fixed to the inner surface of the upright plate 2 to support the hinge mechanism, transmission mechanism, interlocking mechanism, locking mechanism, and pressure balancing mechanism. The stiffener 7 includes a first stiffener 71 and a second stiffener 72. The first stiffener 71 is welded and fixed to the connection between the upright plate 2 and the base plate 1, and the second stiffener 72 is welded and fixed to the connection between the fifth support plate 55 and the arc plate 3. The support plate 4 is fixedly installed on the left side of the base plate 1 by welding. The upper part of the support plate 4 is welded with a diagonal tie 6 and connected and fixed to the base plate 1. The triangular frame structure of base plate 1-vertical plate 2-arc plate 3, along with the support of stiffening plate 7, support plate 5, and diagonal tie rod 6, effectively ensures the strength and rigidity of the test device and prevents the test device from becoming unstable during seismic testing.

[0026] Furthermore, the support plate 5 includes a first support plate 51, a second support plate 52, a third support plate 53, a fourth support plate 54, and a fifth support plate 55. The first support plate 51 is located on the upper left side of the arc plate 3, the second support plate 52 is located below the first support plate 51, the third support plate 53, the second support plate 52, and the arc plate 3 form a triangular structure, the fourth support plate 54 is located in the middle of the arc plate 3, the fifth support plate 55 is located above the fourth support plate 54, and the sixth support plate 56 is located on the lower right side of the arc plate.

[0027] Furthermore, the surface of the support plate 4 is provided with mechanism mounting holes, and a pressure balancing mechanism, a locking mechanism, and a hinge mechanism are fixedly installed on the support plate 4.

[0028] Furthermore, the support plate 5 is provided with an anti-detachment structure.

[0029] Furthermore, the base plate 1 has a reserved interface for connecting to the seismic test bench. By directly connecting to the test bench through the reserved interface, the positional deviation of the segmented platform is avoided, multiple interfaces are reduced, and rapid installation is ensured.

[0030] Furthermore, the base plate 1, upright plate 2, arc plate 3, support plate 4, support plate 5, diagonal tie rod 6, and stiffening plate 7 are an integrated welded structure, forming an overall frame. The integrated structure avoids possible positional deviations after the segmented platform is raised, ensuring that the seismic test is carried out smoothly and accurately. Moreover, the rigidity of the overall frame is better than that of the segmented structure, further ensuring the strength and rigidity of the test device.

[0031] Implementation process of this device: The base plate 1 of this device is securely connected to the seismic test bench via the pre-reserved interface on it, ensuring that the entire device is stably fixed on the test bench. At this time, the triangular frame structure formed by the base plate 1, the vertical plate 2, and the arc plate 3, along with the supporting role of the stiffening plate 7 and the diagonal tie 6, ensures the strength and rigidity of the device itself in advance, avoiding the impact of device instability on the test results during the test. According to the requirements of simulating actual installation conditions, the hinge mechanism, transmission mechanism, interlocking mechanism, locking mechanism and pressure balancing mechanism are respectively installed on the support plates 5 and support plates 4 of the device. The interlocking mechanism is installed on the first support plate 51 and the fifth support plate 55, the pressure balancing mechanism is installed on the second support plate 52, the third support plate 53, the fourth support plate 54, the transmission mechanism is installed on the fourth support plate 54, and the pressure balancing mechanism, locking mechanism and hinge mechanism are installed on the support plate 4. Before the test, check whether all mechanisms are securely and firmly installed on the support plate 5, the upright plate 2 or the arc plate 3, and confirm that the installation method is in line with the actual working conditions, without loosening or positional deviation, to ensure the accuracy of the test. The seismic test bench was activated to conduct seismic tests on the device and its various installed mechanisms. At this time, the integrated welded frame of the device avoided positional deviations of the segmented platforms, and the triangular frame structure and the support plates 7 and 5 further ensured the stability of the device itself, ensuring that the test was conducted smoothly and accurately.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 or all of the technical features therein.
