Description

Technical Field

[0001] This utility model relates to the field of computer-aided engineering technology, and in particular to a device for simulating and analyzing the mechanical properties of key components of power plant equipment. Background Technology

[0002] Key components of power plant equipment include boilers, steam turbines, and generators, which play a crucial role in energy conversion. They operate in harsh environments, and their mechanical properties determine safety. Based on this, mechanical property simulation and analysis devices have emerged. These devices use simulation technology to simulate working conditions, analyze stress distribution, evaluate performance, predict lifespan, and provide support for optimized design.

[0003] Traditional simulation and analysis devices for the mechanical properties of key components in power plant equipment operate by applying a set mechanical load to the tested component to simulate its stress under actual working conditions, thereby obtaining its mechanical parameters such as stress and strain. This device relies on natural environmental heat dissipation during testing. However, in practical use, these devices suffer from uncontrollable testing temperatures, insufficient heat dissipation under high-temperature conditions, leading to fluctuations in component performance and unsatisfactory repeatability of test results. Existing simulation and analysis devices for the mechanical properties of key components in power plant equipment introduce a high-temperature testing module, using a heating unit to place the tested component in a high-temperature environment to simulate its actual working state under a thermo-mechanical coupling field. However, in practical use, these devices suffer from heat accumulation during continuous operation of the high-temperature testing module, lacking a dedicated temperature control structure. This causes the tested components to exceed their normal operating range due to excessively high temperatures, thus affecting the validity and reliability of the collected data. Therefore, a new simulation and analysis device for the mechanical properties of key components in power plant equipment is proposed to address these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a simulation analysis device for the mechanical properties of key components of power plant equipment, which aims to improve the problem in the prior art where the test components exceed their normal operating range due to excessive temperature, thereby affecting the validity of the collected data.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a simulation analysis device for the mechanical characteristics of key components of power plant equipment, comprising a top plate, a constant temperature mechanism provided on the top of the outer wall of the top plate, a bottom plate fixedly connected to the bottom of the outer wall of the top plate, and a shock-absorbing mechanism provided on the inner wall. The constant temperature mechanism includes a base, the bottom of the outer wall of the base is fixedly connected to the top of the outer wall of the top plate, a temperature sensor is fixedly connected to the front side of the outer wall of the base, a fixing frame is fixedly connected to the top of the outer wall of the base, multiple heat dissipation grooves are provided on the left and right sides of the outer wall of the base, a limiting groove is provided at the bottom of the outer wall of the base, a flow component is provided on the front side of the outer wall of the base, a conduction component is provided on the top of the outer wall of the base, and a receiving component is provided on the top of the outer wall of the base.

[0007] As a further description of the above technical solution: The shock-absorbing mechanism includes a foot pad, the top of which is fixedly connected to the bottom of the outer wall of the sliding column.

[0008] As a further description of the above technical solution: The circulation component includes an air pump, the outer wall of which is fixedly connected to the outer wall of the base, and the outer wall of the air pump is connected to an air pipe.

[0009] As a further description of the above technical solution: The conductive component includes a heat sink, the outer wall of which is fixedly connected to the top of the outer wall of the base, and a locking groove is provided at the bottom of the outer wall of the base.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the internal environment is continuously monitored by a temperature sensor.

Finally, the hot air is discharged by the heat exhaust tank. The test sample is placed in a high temperature and corrosion resistant inner liner. Its outer shell and sealing cover together form a sealed heat insulation space, which effectively prevents heat loss and ensures operational safety, ensuring that the resistive metal material being tested is always operating in a precise, stable and suitable temperature environment.

[0014] 2. In this invention, the entire device is supported by foot pads. When external vibrations are transmitted, the spring connected to the sliding column responds quickly, effectively filtering and absorbing most of the impact energy using its own preload. Simultaneously, the sliding column slides controllably within the fixed column, further offsetting residual vibrations. The top fixing button prevents excessive displacement of the components, ensuring smooth and reliable operation. This collaborative working mechanism continuously buffers vibrations and impacts from all directions, effectively protecting core components and extending their service life.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The constant temperature mechanism 3 includes a base 301, which serves as the frame of the structure itself. The bottom of the outer wall of the base 301 is fixedly connected to the top of the outer wall of the top plate 1. A temperature sensor 302 is fixedly connected to the front of the outer wall of the base 301 to monitor the real-time temperature in the structure, ensuring that the test component is always at the optimal temperature to ensure the accuracy of the test. A fixing frame 303 is fixedly connected to the top of the outer wall of the base 301 to fix the outer shell 3081. Multiple heat dissipation grooves 304 are provided on both the left and right sides of the outer wall of the base 301 to dissipate heat. The generated heat is discharged through the slots. A limiting groove 305 is provided at the bottom of the outer wall of the base 301 for fitting the top plate 1 into the base 301. A flow assembly 306 is provided on the front side of the outer wall of the base 301. The flow assembly 306 includes an air pump 3061, which is used to draw airflow from the environment into the heat dissipation area to increase the airflow rate. The outer wall of the air pump 3061 is fixedly connected to the outer wall of the base 301. An air pipe 3062 is connected to the outer wall of the air pump 3061, which is the airflow channel. A conduction assembly is provided at the top of the outer wall of the base 301. 307, the heat conduction component 307 includes a heat sink 3071, which is used to conduct heat generated by the components. The outer wall of the heat sink 3071 is fixedly connected to the top of the outer wall of the base 301. The bottom of the outer wall of the base 301 has a locking groove 3072 for fixing the heat sink 3071. The top of the outer wall of the base 301 is provided with a receiving component 308, which includes a housing 3081. It is the structural foundation of the equipment, providing mechanical support and strength assurance; at the same time, it is the first heat insulation barrier, protecting the safety of operators and reducing... With minimal heat loss and improved energy efficiency, the outer wall of the outer shell 3081 is fixedly connected to the top of the outer wall of the base 301. The inner wall of the outer shell 3081 is fixedly connected to the inner liner 3082, which is used to place the sample to be tested. Its material must be resistant to high temperature and corrosion to ensure a pure and stable testing environment without affecting the sample itself. The top of the outer wall of the outer shell 3081 is fixedly connected to the sealing cover 3083, which ensures the airtightness of the testing space and prevents the exchange of air between the inside and outside. The entire structure enables real-time cooling of resistive metal materials to ensure that they always operate at normal temperature. Specifically, a temperature sensor 302 is arranged on the front side of the base 301. This sensor continuously monitors the thermal state of the internal environment, keeping the test components under suitable temperature conditions, thereby ensuring the effectiveness and reliability of the test process. A fixing frame 303 is installed on the top of the base 301 to stably support the outer shell 3081. Several heat dissipation slots 304 are opened on both sides of the base 301, allowing excess heat generated during operation to dissipate outward through these slots. A limiting slot 305 is designed at the bottom of the base 301 to achieve a matching positioning with the top plate 1. A circulation assembly 306 is also provided on the front side of the base 301. The core of this assembly is an air pump 3061, which is fixed to the surface of the base 301 and can introduce external air into the mechanism to enhance airflow circulation and assist in heat dissipation. The air pump 3061 is connected to a pipe, which serves as the main channel for gas transmission. The heat sink 3071 is in contact with the surface of the base 301 and is responsible for dissipating the heat generated by the electronic components. The base 301 has a locking groove 3072 at its bottom for fixing the position of the heat sink 3071. The top of the base 301 is equipped with a housing component 308. The outer shell 3081, as the main structural body of the whole device, provides mechanical strength and support, and also plays a role in initial heat insulation, protecting the safety of operators and reducing heat loss, thus improving energy efficiency. The inner liner 3082 is installed inside the outer shell 3081, providing a space for the sample to be tested. Its material has high temperature resistance and corrosion resistance, which can maintain the purity and stability of the test environment without interfering with the sample. The top of the outer shell 3081 is equipped with a sealing cover 3083, which is used to seal the test space, prevent the exchange of air between the inside and outside, and maintain a stable internal temperature environment. Overall, through the coordinated work of temperature monitoring, airflow circulation, and heat conduction, real-time temperature control of resistive metal materials is achieved, enabling them to operate continuously within the normal temperature range.

[0019] Reference Figures 1-3 The damping mechanism 4 includes a fixed column 401 to ensure the stability of its structure. The outer wall of the fixed column 401 is fixedly connected to the inner wall of the base plate 2. A sliding column 403 is fixedly connected to the inner wall of the fixed column 401 and slides between the fixed columns 401 to offset the vibration. The outer wall of the base plate 2 has a fixing hole 402. A fixing button 404 is fixedly connected to the top of the outer wall of the sliding column 403 to fix the top and prevent excessive displacement of the sliding column 403. A spring 405 is fixedly connected to the outer wall of the sliding column 403 to filter the vibration using its own preload. The damping mechanism 4 includes a foot pad 406 to support the entire device. The top of the outer wall of the foot pad 406 is fixedly connected to the bottom of the outer wall of the sliding column 403. The entire structure filters the vibration generated by the device. Specifically, the fixed column 401 is connected to the base plate 2. The fixed column 401 integrates a sliding column 403, which can slide within the fixed column 401 to offset the vibration from the outside. The base plate 2 has fixing holes 402 to enhance the stability of the installation. The sliding column 403 is equipped with a fixing button 404, which limits the range of movement of the sliding column 403 to prevent slippage. The sliding column 403 is surrounded by a spring 405, which buffers and absorbs the transmitted vibration through its own preload. The damping mechanism 4 also includes a foot pad 406, which is connected to the bottom of the sliding column 403 to provide a stable support foundation for the device. When the device is vibrated, the vibration energy is first transmitted to the sliding column 403, causing it to slide. The spring 405 then deforms, converting mechanical energy into elastic potential energy, gradually dissipating the vibration, and finally achieving efficient filtering of the vibration of the entire device.

[0020] Reference Figures 2-3 A fixed base 6 is fixedly connected to the top of the outer wall of the top plate 1. A vacuum pump 5 is fixedly connected to the top of the outer wall of the fixed base 6. It actively discharges air and other gas molecules in the vacuum tank 7, thereby creating the required low-pressure environment in the tank and maintaining the stability of the environment to meet the test requirements. The outer wall of the vacuum pump 5 is connected to the second air pipe 8. The outer wall of the second air pipe 8 is connected to the vacuum tank 7, which seals a high-strength vacuum cavity to provide a pure and interference-free test environment for the test sample that is isolated from the outside world. Specifically, a fixed base 6 is installed above the top plate 1, and a vacuum pump 5 is fixed on the fixed base 6. This device actively extracts air and other gas molecules from the inside of the vacuum tank 7, thereby forming and maintaining a stable space with a low pressure inside the tank to meet specific test conditions. The vacuum pump 5 is connected to a section of gas pipe 8, and the other end of the gas pipe 8 is connected to the vacuum tank 7. The vacuum tank 7, as a sealed cavity, can provide a pure and interference-free environment for the test sample that is completely isolated from the outside world.

[0021] Working principle: First, the internal environment is continuously monitored by the temperature sensor 302. When the temperature needs to be lowered, the structure will activate the air pump 3061 to draw in the cooling airflow from the external environment. The airflow is guided through the air pipe 3062 to the heat sink 3071, which carries away the accumulated heat. Finally, the hot air is discharged from the structure through multiple heat dissipation slots 304 on the side of the base 301. The test sample is placed in the inner liner 3082 made of a special material. The inner liner 3082 has excellent high temperature resistance and corrosion resistance, providing a clean and stable test space for the sample. The inner liner 3082 is wrapped by the outer shell 3081 and the top is equipped with a sealing cover 3083. Together, they form a sealed heat-insulating environment. This can effectively prevent unnecessary heat loss from the inside, isolate external environmental interference, and ensure the safety of the operation process. The coordinated work of this series of components ensures that the resistive metal material being tested can operate under a stable and suitable set temperature condition, thus providing a solid guarantee for the authenticity of the test data. Furthermore, the foot pad 406 provides basic support for the entire device. When external vibrations are transmitted to the device, the spring 405 connected to the slide column 403 will respond immediately. The spring 405 uses its own preload to effectively filter and absorb most of the energy contained in the impact. At the same time, the slide column 403 will slide within the design range inside the fixed column 401. This relative movement further offsets the remaining vibration effect. The fixing button 404 installed on the top of the slide column 403 plays a limiting role, which can prevent the slide column 403 from generating excessive displacement during the movement, thereby ensuring the smoothness and controllability of the entire vibration damping operation. The foot pad 406, fixed column 401, slide column 403, spring 405 and fixing button 404 together form an organic whole. Their collaborative working mechanism can continuously cope with vibrations and impacts from different directions, significantly reducing the vibration level transmitted to the core part of the device. This is crucial for protecting the internal precision components from damage, and thus helps to extend the service life of the entire device.
