Abstract
Description
Technical Field

[0002] Workers put nuclear power valves through simulated earthquakes to ensure that these key safety components can maintain structural integrity and functional reliability in the face of extreme natural disasters such as earthquakes, prevent possible leakage and other safety accidents, meet strict safety standards and regulatory requirements, ensure the safety of nuclear power plant workers and surrounding residents, and maintain the long-term stable operation and good reputation of the nuclear power plant.
[0003] Currently, valve vibration resistance testing relies on workers using hammers to knock on nuclear power valves to simulate earthquake vibrations, thereby causing the nuclear power valves to vibrate. Sensors are then used to monitor data such as the amplitude and frequency of the vibration to check the quality of the nuclear power valves. Although workers can change the size and speed of the knocking force to simulate the amplitude and frequency, after knocking for a period of time, they will become physically exhausted and the knocking time will not be long enough. As a result, the data of the simulation results is insufficient, which increases the workers' misjudgment rate, which is time-consuming and labor-intensive. Utility Model Content

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0027] Example 1
[0028] Reference Figures 1 to 4 , which is the first embodiment of the present utility model, provides a vibration simulation generating device. By setting a resonance member 201 and a collision member 202, it can prevent workers from knocking for a short time due to physical exhaustion after knocking for a period of time, so that the data of the simulation results are insufficient, thereby increasing the workers' misjudgment rate and avoiding workers' time and energy consumption.
[0029] Specifically, the bearing assembly 100 includes a fixing frame 101 and a placing frame 102. The fixing frame 101 provides support for the vibration assembly 200, and the placing frame 102 provides a storage space for the valve. It should be noted that there are two fixing frames 101, and the placing frame 102 is arranged between the two fixing frames 101; the vibration assembly 200 provides a vibration source for detecting the valve, which includes a resonant member 201 arranged on the placing frame 102 and a collision member 202 arranged in the resonant member 201. It should be noted that there are two vibration assemblies 200, one end of the two vibration sources passes through the two fixing frames 101 in a mirrored manner, and the other end is embedded in the placing frame 102.
[0030] A damper is provided between the bearing assembly 100 and the vibration assembly 200 to prevent the vibration assembly 200 from simulating an earthquake and generating vibration that affects the detection assembly 100 , thereby preventing the electronic components in the detection assembly 100 from becoming loose.
[0031] In summary, by setting the resonance member 201 and the collision member 202, the valve is installed in the placement hole of the mounting frame 102. When the power is turned on, the collision member 202 rotates and strikes the inner wall of the resonance member 201, generating different vibrations at the same time, simulating the detection of the valve vibration performance, saving time and effort.
[0032] Example 2
[0033] Reference Figures 1 to 4 This is the second embodiment of the utility model. Different from the previous embodiment, by providing a resonance member 201 and a collision member 202, it is possible to prevent workers from knocking for a short time due to physical exhaustion after knocking for a period of time, resulting in insufficient data for the simulation results, thereby increasing the workers' misjudgment rate and avoiding wasting time and energy.
[0034] Specifically, the collision member 202 includes a protective cover 202 d fixedly connected to the side wall of the mounting frame 102 .
[0035] A motor 202 c is provided on a side of the protection cover 202 d away from the mounting frame 102 .
[0036] The output end of the motor 202c is provided with a fixing rod 202a.
[0037] A first limiting ring 202b, a second limiting ring 202h and a third limiting ring 202i are fixedly sleeved on the fixing rod 202a.
[0038] The third limiting collar 202i is provided with a first rotating rod 202e, the second limiting collar 202h is provided with a second rotating rod 202f, and the first limiting collar 202b is provided with a third rotating rod 202g.
[0039] The length of the first rotating rod 202e is equal to the length of the second rotating rod 202f, and the length of the third rotating rod 202g is longer than the length of the first rotating rod 202e.
[0040] The resonant member 201 includes a simulation tube 201 a disposed on a protective cover 202 d , and the simulation tube 201 a can accommodate the collision member 202 .
[0041] The collision member 202 includes a protective cover 202d fixedly connected to the side wall of the mounting frame 102. The protective cover 202d is helpful in protecting the motor 202c from external collisions. The motor 202c is provided on the side of the protective cover 202d away from the mounting frame 102. The model of the motor 202c is ZGA37RG.
[0042] The output end of the motor 202c is provided with a fixed rod 202a which does not interfere with the inner wall of the simulation cylinder 201a, thereby avoiding increasing the friction when the fixed rod 202a rotates.
[0043] The first rotating rod 202e and the second rotating rod 202f have the same length and equal mass, but the number of the first protrusions 201b and the second protrusions 201c corresponding to the first rotating rod 202e and the second rotating rod 202f is different, so that the number of times of impact of the first rotating rod 202e and the second rotating rod 202f on the first protrusions 201b and the second protrusions 201c is different at the same rotating speed of the motor 202c, thereby causing different vibration frequencies.
[0044] The third rotating rod 202g has the same mass as the first rotating rod 202e, but the length of the third rotating rod 202g is longer than that of the first rotating rod 202e, and the number of the first protrusions 201b and the third protrusions 201d corresponding to the first rotating rod 202e and the third rotating rod 202g is equal, so that the vibration caused by the impact of the first rotating rod 202e on the first protrusions 201b and the vibration caused by the impact of the third rotating rod 202g on the third protrusions 201d are different in size at the same rotating speed of the motor 202c.
[0045] The vibration sensor is arranged on the outer wall of the simulation cylinder 201a, and the model of the sensor is CYT9200.
[0046] In summary, by arranging the resonance part 201 and the collision part 202, installing the valve in the placing hole of the placing frame 102, connecting the power supply, rotating the motor 202c, thereby rotating the fixed rod 202a, the third limiting sleeve ring 202i, the second limiting sleeve ring 202h and the first limiting sleeve ring 202b, and making the first rotating rod 202e, the second rotating rod 202f and the third rotating rod 202g knock the first protrusions 201b, the second protrusions 201c and the third protrusions 201d respectively under the action of the centrifugal force, different vibrations and frequencies are generated, and the information is collected through the vibration sensor on the simulation cylinder 201a to detect the quality of the nuclear power valve, the detection of the valve vibration performance is simulated, time and labor are saved, and the workers are prevented from knocking for a short time due to physical exhaustion, so that the simulation result is insufficient in data and the misjudgment rate of the workers is improved.
[0047] Embodiment 3
[0048] Reference Figures 1 to 4 The third embodiment of the utility model is different from the previous embodiment, and the motor 202c is arranged, so that the comprehensiveness of the workers in detecting the range of the nuclear power valve under the seismic amplitude and frequency is improved.
[0049] Specifically, the inner wall of the simulation cylinder 201a is provided with a first protrusion 201b that can interfere with the first rotating rod 202e, a second protrusion 201c that can interfere with the second rotating rod 202f, and a third protrusion 201d that can interfere with the third rotating rod 202g.
[0050] The first protrusion 201b, the second protrusion 201c and the third protrusion 201d are evenly arranged in a circle around the axis of the simulation cylinder 201a.
[0051] The distance between the end of the third protrusion 201d away from the inner wall of the simulation cylinder 201a and the simulation cylinder 201a is shorter than the distance between the end of the first protrusion 201b away from the inner wall of the simulation cylinder 201a and the simulation cylinder 201a, thereby preventing the third rotating rod 202g from being blocked from rotating when it hits the third protrusion 201d.
[0052] In summary, by setting up the motor 202c, the motor 202c can achieve different rotation speeds under the control of the mounting frame 102, and the different rotation speeds of the motor 202c can make the first rotating rod 202e, the second rotating rod 202f and the third rotating rod 202g hit the first protrusion 201b, the second protrusion 201c and the third protrusion 201d with different forces, thereby changing the amplitude and frequency of the vibration, which can improve the comprehensiveness of the range of workers' detection of the amplitude and frequency of earthquakes that nuclear power valves withstand.
