Description

Technical Field

[0001] The present invention relates to the field of ocean-related simulation experiments, and in particular to a simple system for simulating the undulating motion of ocean conditions. Background Art

[0002] Land-based nuclear power plants are susceptible to earthquakes, wind and waves, tsunamis, and other impacts, causing severe sloshing in equipment with free liquid surfaces, such as pressurizers and steam generators. Sloshing causes violent fluctuations in the free liquid surface. These fluctuations not only mechanically impact the vessel walls and equipment within, threatening structural stability, but also generate complex fluid dynamics. The fundamental cause of these phenomena is the additional acceleration introduced by ocean conditions. Among various ocean motions, the additional acceleration introduced by heaving motion is most suitable for theoretical analysis and experimental verification. Currently, nuclear power plants primarily use differential pressure level gauges to monitor the actual water level within pressurizers, steam generators, and other equipment. However, the additional acceleration introduced by heaving motion can cause the measured water level to deviate from the actual level, reducing the accuracy of the equipment's water level measurement. Therefore, the accuracy of liquid level measurement directly impacts the safety and economic efficiency of the entire nuclear power system. Therefore, a well-designed heaving motion system is crucial for the study of thermal hydraulics under ocean conditions.

[0003] Chinese patent CN113686539B discloses a simple system for simulating undulating motion under ocean conditions. The system includes a power input part and a power output part. When in use, the crank is rotated through the cooperation of a high-power motor and a gear reduction box, and then the motion platform is moved up and down by pulling the traction rope; the device can only cause the liquid in the water tank to fluctuate through the vibration caused by the longitudinal movement of the mobile platform, and then measure the fluctuation data.

[0004] However, in reality, the sources of earthquakes that cause ocean waves include not only longitudinal waves but also transverse waves. Therefore, when measuring ocean waves, it is necessary not only to simulate the ocean waves caused by longitudinal wave vibrations, but also to have the ability to generate transverse waves at the same time, so as to accurately measure the experimental data. However, the current equipment has corresponding deficiencies.

[0017] One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. The present invention provides a simple system for simulating the heaving motion of ocean conditions. The worm and turbine cooperate to rotate the second gear. The synchronous and counter-rotating rotation of the two second gears causes the two shifting blocks to alternately shift the shifting frame to move back and forth laterally, thereby achieving the reciprocating transverse motion of the translation seat and the lifting seat. The generated transverse waves can generate corresponding ocean waves.

[0020] 4. In the present invention, when the lead screw rotates, the slider moves along the axial direction of the lead screw, thereby changing the diameter of the circumferential movement of one end of the traction rope, thereby changing the lifting amplitude of the lifting seat and changing the vibration amplitude.

[0021] In summary, the present invention can generate shear waves, simulating the corresponding ocean surges, and can also generate longitudinal waves, simulating the ocean surges caused by longitudinal waves. This device possesses both capabilities, allowing for selection based on needs and high versatility.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0027] like Figure 1 and Figure 2As shown, the simple system for simulating the undulating motion under ocean conditions includes: a translation seat 2, a column 3, a top beam 4, a lifting seat 5, a simulated water tank 6 and a longitudinal vibration mechanism 9. The column 3 is installed on the translation seat 2. The column 3 is used to support the top beam 4. The top beam 4 is composed of two cross beams and two longitudinal beams. The main body is in the shape of a U.S. There are four columns 3. The four corners of the main part of the top beam 4 are installed on the top of the four columns 3. The four corners of the lifting seat 5 are slidably installed on the four columns 3 respectively. The limit of the four columns 3 can ensure that the lifting seat 5 only moves in the up and down direction. The simulated water tank 6 is fixedly installed on the lifting seat 5 by bolt connection, and the two can move synchronously. The simulated water tank 6 is a hollow cavity with an open top and is filled with seawater. When conducting experimental research, it is necessary to install several pressure sensors on the lifting seat 5. Their sensors are in contact with different positions of the simulated water tank 6 to obtain pressure changes at different positions. In addition, two connecting plates 501 are symmetrically installed on the lifting seat 5. The two connecting plates 501 are respectively located on both sides of the simulated water tank 6 and are symmetrically arranged relative to the simulated water tank 6.

[0028] The pressure sensor used in this embodiment is a PT5310 model. During use, it is installed at multiple locations between the upper surface of the lifting seat 5 and the simulated water tank 6. Simultaneously, pressure sensors of the same model are installed on the side walls of the simulated water tank as needed. During use, when pressure acts on the sensor's elastic diaphragm, the diaphragm deforms, causing its internal resistance to change. These resistors form a Wheatstone bridge. When the bridge loses balance, it generates a voltage output signal proportional to the pressure. This signal is amplified and conditioned by a subsequent processing circuit, and ultimately displayed on an external display, thereby converting pressure into an electrical signal and achieving the purpose of measuring pressure. The above process is the conventional operating principle of the PT5310 model pressure sensor and is a prior art technology. Workers can obtain the required data by observing the changes in pressure signals transmitted from multiple points.

[0029] like Figure 2 、 Figure 6 、 Figure 7 and Figure 8As shown, a longitudinal vibration mechanism 9 is mounted on the translation base 2. This mechanism is used to drive the lifting base 5 to move longitudinally back and forth. As the lifting base 5 reciprocates up and down, it simulates the generation of longitudinal ocean waves, causing the seawater in the simulated water tank 6 to fluctuate. This allows various sensors to detect pressure changes caused by the ocean's heaving at various locations. The longitudinal vibration mechanism 9 includes a second motor 91, a reducer 92, a turntable 93, a fixed box 94, a lead screw 95, a slider 96, and a connector 97. The second motor 91 is mounted on the reducer 92, which is mounted on the translation base 2 via a bracket. In this embodiment, the second motor 91 is a Y355-4 motor, which has high power and meets experimental requirements. The reducer 92 is an SGF55-H dual-output reducer, which increases the torque of the second motor 91 and has two symmetrical output terminals. Two turntables 93 are mounted on the two output terminals of the reducer 92, ensuring that the two turntables 93 rotate synchronously and in the same direction. There are two connectors 97, mounted on two turntables 93 respectively. One end of the traction rope 10 is rotatably mounted on the connector 97, and the other end of the traction rope 10 is connected to the connecting plate on the lifting seat 5. The connector 97 is eccentrically arranged relative to the turntable 93. When the turntable 93 rotates, the traction rope 10 can be used to pull the lifting seat 5 up and down, thereby simulating the formation of longitudinal waves. In order to be able to adjust the eccentric position of the connector 97 relative to the turntable 93, thereby changing the lifting amplitude of the lifting seat 5, the connector 97 can be connected to the turntable 93 through an adjustment part. The fixed box 94, the lead screw 95 and the slider 96 together constitute the adjustment part. The fixed box 94 is fixedly mounted on the turntable 93, and its outer wall is located at a position passing through the center position of the turntable 93. The fixed box 94 is a hollow cavity with one side open, and its open side forms a slideway, which is away from the turntable 93. One end of a lead screw 95 is rotatably mounted within a fixed housing 94, while the other end of the lead screw 95 extends beyond the outer wall of the fixed housing 94. A blind slot is provided on the end extending beyond the fixed housing 94 to facilitate rotation of the lead screw 95 using a screwdriver. A slider 96 is threadedly connected to the lead screw 95 and engages with a slideway on the fixed housing 94. Rotation of the lead screw 95 causes the slider 96 to move axially along the lead screw 95, while the slideway prevents the slider from rotating. In this embodiment, the lead screw 95 is a trapezoidal lead screw with a trapezoidal thread profile and a 30° thread angle. The slider 96 is provided with a matching internal thread, a technique known in the art. When the trapezoidal lead screw serves as a transmission component, in the absence of an external driving force, the friction between the threaded pairs prevents axial movement of the object threaded onto the lead screw, thereby achieving self-locking. This embodiment ensures that when the lead screw 95 is rotated without the action of an external force, the slider 96 will not move. The connecting member 97 is installed on the slider 96. When the slider 96 moves, the lifting range of the lifting seat 5 can be changed.

[0030] Furthermore, the translation seat 2 and the top beam 4 are each mounted with a fixed pulley 8. The main portion of the top beam 4 is also mounted with two sub-beams, the positions of which correspond to the positions of the two connecting plates 501. The two fixed pulleys 8 on the top beam 4 are respectively mounted on the two sub-beams. The two fixed pulleys on the translation seat 2 correspond to the positions of the connecting plates 501. A traction rope 10 is wound around the fixed pulley 8. The limited guide of the fixed pulley 8 can change the pulling direction of the traction rope 10, ensuring that the lifting seat 5 is pulled in the vertical direction. The fixed pulley 8 has an I-shaped cross-section, and the traction rope 10 is inserted into the I-shaped groove of the fixed pulley 8 to prevent it from being detached.

[0031] In actual use, pre-rotate the lead screw 95 to move the slider 96 axially along it. Once the lead screw 95 is in position, stop rotating it. Securely connect the ends of the traction rope 10 to the connector 97 and the connecting plate 501, respectively, to ensure the rope is taut. Turn on the second motor 91, which, through the reducer 92, rotates the two turntables 93. This causes the lift base 5 to move up and down using the traction rope 10, causing the liquid in the simulated water tank 6 to begin fluctuating. This allows the simulation test to begin.

[0032] This solution can simulate the generation of transverse waves in the ocean, using transverse waves to cause the sea water to fluctuate, thereby realizing relevant simulation tests.

[0033] In order to simulate the shear waves that cause the ocean waves to rise and fall, the following scheme is proposed. Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the translation seat 2 is installed on the base 1 through the transverse vibration mechanism 7. The transverse vibration mechanism 7 can make the translation seat 2 move back and forth laterally, thereby simulating the generation of transverse waves. The transverse vibration mechanism 7 includes a worm 71, a first motor 72, a positioning rod 73, a worm wheel 74, a second gear 75, a shift block 76 and a shift frame 77. There are several positioning rods 73, which are respectively installed on the base 1. The translation seat 2 is slidably installed on the positioning rods 73. The positioning rods 73 are limited to ensure that the translation seat 2 can only move along the axial direction of the positioning rods 73. The worm 71 is rotatably installed on the base 1, and the first motor 72 is installed on the base 1. The output end of the first motor 72 is connected to one end of the worm 71. Turning on the first motor 72 can drive the worm 71 to rotate. A worm gear 74 is rotatably mounted on base 1 and meshes with worm 71. The two gears form a transmission system. Rotation of worm 71 drives worm gear 74. The worm gear selected in this embodiment is self-locking, as is common knowledge in the prior art. The lead angle of worm 71 is less than the equivalent friction angle between the teeth of worm gear 74, resulting in a self-locking property. When worm 71 stops rotating, worm gear 74 does not rotate. First motor 72 is a self-locking motor with a lockable output. Two second gears 75 are rotatably mounted on base 1, and another second gear 75 is mounted on worm gear 74. The two second gears 75 mesh with each other. Rotation of worm gear 74 drives rotation of the second gear 75 connected to it, simultaneously causing the other second gear 75 to rotate synchronously and in the opposite direction. A shift block 76 is mounted on the second gear 75. The shifting frame 77 is mounted on the lower surface of the translation base 2. The positions of the shifting frame 77 and the shifting block 76 correspond to each other. The shifting frame 77 has two protrusions corresponding to the two second gears 75, and each corresponding to the shifting block 76. There is an angle between the shifting blocks 76 on the two second gears 75, and the two shifting blocks 76 do not contact the protrusions at the same time. As the two second gears 75 rotate, the shifting blocks 76 can shift the protrusions.

[0034] When in use, the first motor 72 is turned on to drive the worm 71 to rotate, thereby rotating the worm wheel 74, and the two second gears 75 start to rotate synchronously and oppositely. One of the shift blocks 76 shifts the opposite protrusion on the shift frame 77, causing the shift frame 77 and the translation seat 2 to move a certain distance until the shift block 76 breaks away from contact with the protrusion. Then the shift block 76 on the other second gear 75 starts to contact the other protrusion, shifting the shift frame 77 and the translation seat 2 in opposite directions. By continuing to operate in the above manner, the translation seat 2 can move back and forth laterally to form a transverse wave.

[0035] The solution can simulate the formation of longitudinal ocean waves, thereby conducting simulation experiments on the undulation of seawater caused by longitudinal waves. At the same time, the device can adjust the amplitude of longitudinal undulation.

[0036] Not only that, the device also has the ability to simulate the generation of shear waves and longitudinal waves. When conducting tests, it can generate shear waves or longitudinal waves separately, or both at the same time. The device is highly flexible and one device can meet the needs, saving equipment costs.

[0037] The simple system for simulating the undulating motion of ocean conditions also includes a static mechanism 11, which is installed on the top beam 4 and its position corresponds to the position of the simulated water tank 6. During the experiment, the seawater simulating the undulating waves has strong kinetic energy due to the shaking, and it takes a long time for the water to return to calm after stopping the test. Therefore, the static mechanism 11 is used to quickly restore the liquid in the simulated water tank 6 to a static state. Figure 1 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12As shown, the stationary mechanism 11 includes a housing 111, a lifting slot 112, a sliding rod 113, a mounting frame 114, a rotating rod 115, a first gear 116, a contact plate 117, a through hole 118, a movable plate 119, a sliding slot 1110, a supporting rod 1111, and a rack 1112. The housing 111 is mounted on the top beam 4 and is a hollow structure with an open bottom. There are a plurality of mounting frames 114, each equidistantly mounted within the housing 111. The rotating rod 115 is rotatably mounted on the mounting frame 114. The contact plates 117 are mounted on the rotating rod 115. The contact plates 117 are tilted and rotate synchronously with the rotating rod 115 to be retracted into the housing 111. At this time, the contact plates 117 overlap. When the contact plates 117 rotate in the opposite direction, they spread apart and remain tilted. There are several through holes 118 arranged in an array on the contact plate 117, and the through holes 118 are used for drainage. There are several lifting grooves 112, which are installed at equal intervals in the housing 111. The slide rod 113 is installed on the mounting frame 114, and the slide rod 113 is slidably connected to the lifting groove 112. The portion of the slide rod 113 embedded in the lifting groove 112 is rectangular in shape, which adapts to the shape of the inner cavity of the lifting groove 112. This can prevent the slide rod 113 from rotating, thereby ensuring the stability of the sliding rod 113 and the mounting frame 114 during the lifting and lowering movement. The support rod 1111 is installed in the housing 111, and the movable plate 119 is slidably mounted on the support rod 1111. The movable plate 119 can move along the axial direction of the support rod 1111. The chute 1110 is provided on the movable plate 119, and the slide rod 113 is slidably installed in the chute 1110. The chute 1110 is tilted. When the movable plate 119 moves, the slide rod 113 and the mounting bracket 114 can be moved up and down by the cooperation of the chute 1110 and the lifting groove 112. At the same time, the movable plate 119 is kept stable by the combined action of the mounting bracket 114 and the lifting groove 112. An electric push rod 12 is installed on the top beam 4. The output end of the electric push rod 12 extends into the housing 111 and is connected to the movable plate 119. Turning on the electric push rod 12 can push the movable plate 119 to move. The first gear 116 is installed at both ends of the rotating rod 115. The rack 1112 is installed on the housing 111. The first gear 116 is meshed with the rack 1112. When the mounting bracket 114 moves downward, the first gear 116 and the rack 1112 are engaged with each other, so that the rotating rod 115 and the contact plate 117 can rotate.

[0038] In actual use, after an experiment is completed and the equipment generating the corresponding vibration is shut down, turning on the electric push rod 12 can drive the movable plate 119 to move along the axial direction of the support rod 1111. The combined position limiting function of the slide groove 1110 and the lifting groove 112 can move the slide rod 113 and the mounting bracket 114, and at the same time, move the contact plate 117 downward. At the same time, the cooperation between the first gear 116 and the rack 1112 can cause the rotating rod 115 to rotate while descending, thereby ensuring that the contact plate 117 rotates while descending. When the rotating rod 115 descends to the lowest end, the contact plate 117 is tilted and inserted into the simulated water tank 6, and the liquid level contacts the middle of the contact plate 117. At this time, because the contact plate 117 is tilted, the liquid surface, whether it fluctuates up and down or sways laterally, contacts the surface of the contact plate 117, thereby absorbing the kinetic energy transmitted in the corresponding force component direction. At the same time, when the liquid surface impacts the contact plate 117, some seawater leaks through the through-holes 118. This not only further quickly absorbs and consumes the kinetic energy of the seawater, allowing the seawater to quickly return to calm for the next experiment, but also prevents the formation of local vortices through the leakage of through-holes 118. In addition, the tilt angle of the contact plate 117 and the leakage of water through the through-holes 118 can prevent the contact plate 117 from being damaged by large forces.

[0039] The device is capable of quickly stabilizing seawater, dissipating its kinetic energy. This facilitates subsequent experiments. It also has a self-protection capability to prevent damage and extend its service life.

[0040] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
