[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0041] In one specific embodiment of this application, a clamping device for a laser amplifier is provided, comprising:

[0042] A limiting frame, comprising two U-shaped frames 1 joined together, wherein the U-shaped frames have a cavity inside which liquid is contained, and a partition 2 is provided inside the cavity, the partition 2 dividing the cavity into multiple sub-chambers, and the partition 2 has a connecting hole connecting the sub-chambers on both sides of the partition 2, and each sub-chamber has a sphere 6 inside;

[0043] Buffer 3, one buffer bladder is provided for each of the U-shaped frames, and the buffer bladder is in communication with the cavity of the U-shaped frame;

[0044] The frequency regulating element 4 is configured to change the flow rate between the cavity of the U-shaped frame and the buffer bladder 3 in response to changes in the vibration frequency of the laser amplifier 5.

[0045] It is understood that the frequency regulating component 4 described in this application is disposed on the channel connecting the cavity of the U-shaped frame and the buffer bladder. It can monitor the vibration frequency of the laser amplifier 5 and then adjust the flow rate between the cavity of the U-shaped elastic limiting frame and the buffer bladder 3 according to the vibration frequency of the laser amplifier 5. Alternatively, it can adaptively adjust the flow rate between the cavity of the U-shaped frame and the buffer bladder 3 as the vibration frequency of the laser amplifier changes.

[0046] It should be noted that, in this application, the U-shape refers to a shape in which two sides are arranged opposite each other, and the same end of the two sides is connected by the bottom edge, forming a rectangular shape with one end open (e.g., Figure 3 (As shown). The side edges and bottom edges can be connected perpendicularly or by chamfering. In some embodiments, the U-shaped elastic limiting frame includes a first border, a second border, and a third border, with the third border perpendicularly connected to both the first and second borders.

[0047] In this application, multiple sub-chambers refer to two or more sub-chambers; in some embodiments, the number of multiple sub-chambers is 30-50.

[0048] When the laser amplifier is subjected to vibration, the inertial motion of the sphere 6 changes the resistance to fluid flow, thereby dissipating the vibrational energy.

[0049] In some embodiments of this application, the U-shaped frame 1 is made of rubber. Since the cavity of the U-shaped frame contains liquid, it can conduct heat to the laser amplifier 5, absorbing its heat. As the liquid temperature rises, the clamping effect of the U-shaped frame 1 on the laser amplifier 5 is increased.

[0050] In some embodiments of this application, the number of limiting frames may be two or more. In some embodiments, two or more limiting frames are configured on a single laser amplifier.

[0051] In some embodiments of this application, the liquid is silicone oil or an aqueous solution of ethylene glycol.

[0052] In some embodiments of this application, the partition 2 includes an inner plate and an outer plate 22 surrounding the outer periphery of the inner plate 21. The outer plate 22 is connected to the inner wall of the cavity of the U-shaped frame. The inner plate 21 has at least one first flow hole 211 for connecting the sub-cavities on both sides of the partition 2.

[0053] In some embodiments of this application, the outer plate 22 is made of rubber. The rubber outer plate is elastic and can buffer the force between the inner plate 21 and the U-shaped frame 1, reducing hard collisions caused by vibration. The first flow hole 211 on the inner plate 21 connects adjacent sub-chambers, ensuring the flow of liquid between the sub-chambers. When the sphere 6 moves due to vibration in the sub-chamber, the liquid can flow between different sub-chambers through the first flow hole 211, further enhancing the dissipation effect of vibration energy.

[0054] In some embodiments of this application, on at least one surface of the inner plate 21, a swirling groove 212 communicating with each of the first flow holes 211 is provided. During liquid flow, when the liquid enters the swirling groove 212, it forms a rotating flow along the shape of the swirling groove 212. This swirling flow increases the path and time of liquid flow. The liquid rotates, causing the sphere 6 to rotate, increasing the friction between the liquid and the sphere 6 and the wall of the swirling groove 212, thereby consuming more vibrational energy. For example, vibration causes the sphere 6 to push the liquid flow, and the liquid forms a swirling flow after flowing into the swirling groove 212, continuously consuming energy during the swirling process.

[0055] In some embodiments of this application, the number of first flow holes 211 is two or more, and the first flow holes 211 are evenly spaced, as are the swirling grooves on each inner plate surface. In some embodiments, the number of first flow holes 211 is 5-10, and the number of swirling grooves 212 is 5-10. The evenly spaced distribution of multiple swirling grooves 212 ensures that the liquid forms a similar swirling effect at different positions during flow, guaranteeing the uniformity of vibration energy dissipation of the entire separator 2. Regardless of the direction from which the vibration originates, multiple swirling grooves 212 can intervene in the liquid flow, enhancing adaptability to vibrations from different directions.

[0056] In some embodiments of this application, the depth of the swirling channel gradually decreases as the distance from the center of the first flow orifice increases. The depth of the swirling channel 212 increases sequentially from the first end to the last end. As liquid flows into the swirling channel 212, the liquid depth gradually increases with the flow, which changes the flow velocity and pressure distribution of the liquid. The increase in depth causes changes in the inertia of the liquid flow, making the interaction with the sphere 6 more complex and further increasing energy dissipation. For example, the liquid flows faster in shallow areas and slows down in deeper areas. This change in flow velocity will generate more interaction with the sphere 6 and consume more vibrational energy.

[0057] In some embodiments of this application, the frequency regulating component includes a first housing, a fixed plate, and a rotating plate;

[0058] The first housing is installed in the cavity of the U-shaped frame and communicates with the cavity of the buffer bag and the cavity of the U-shaped frame respectively. Along the direction from the end of the first housing that communicates with the buffer bag to the end of the first housing that communicates with the cavity of the U-shaped frame, the fixed plate and the rotating plate are installed in sequence in the first housing, and the axial direction of the fixed plate and the rotating plate is parallel to the flow direction of the liquid.

[0059] The fixed plate has at least one second flow hole, and the rotating plate has at least one third flow hole. The rotating plate can rotate relative to the fixed plate, so that by changing the relative angle between the two, the overlapping area between the second flow hole and the third flow hole can be continuously changed, thereby changing the flow rate between the cavity of the U-shaped frame and the buffer bladder.

[0060] When the laser amplifier vibrates at low frequency, the second and third flow holes overlap, which is conducive to fluid flow. The liquid can flow into the buffer bladder 3 quickly over a large area to relieve pressure and avoid excessive damping that leads to energy accumulation. When the laser amplifier vibrates at high frequency, the overlapping area of ​​the second and third flow holes decreases or even partially closes. The liquid needs to flow through a narrow gap or the gap between the hollow tube 47 and the third flow hole. The flow resistance increases sharply, and the sphere 6 intensifies turbulence, which together improves the high-frequency damping efficiency.

[0061] In some embodiments of this application, the first housing has a circular cross-section and openings at both ends, and the axial directions of the second flow hole and the third flow hole are perpendicular to the cross-section of the first housing.

[0062] In some embodiments of this application, the frequency regulating component further includes axial flow blades, which are installed on the side of the rotating plate near the buffer bladder, and the rotating plate rotates with the rotation of the axial flow blades.

[0063] In some embodiments of this application, each of the second flow holes is provided with a hollow tube, the hollow tube is equipped with a magnetic block, and the hollow tube is elastically connected to the inner wall of the second flow hole by a spring;

[0064] The frequency regulating component also includes a strip magnetic sheet, which has the same magnetism as the magnetic block. The strip magnetic sheet is coaxially mounted with the axial flow blade and rotates with the axial flow blade.

[0065] In some embodiments of this application, the fixing plate is fixedly connected to the inner wall of the first housing, the rotating plate is rotatably connected to the inner wall of the first housing, the rotating plate is made of magnetic material, preferably a magnetic metal, and an electromagnet is installed on the first housing to lock the rotating plate.

[0066] In some embodiments of this application, the frequency regulating component includes a second housing and a screen, wherein the second housing is installed in the cavity of the U-shaped frame and communicates with the buffer bag and the cavity of the U-shaped frame respectively;

[0067] The screen is installed inside the second housing and is perpendicular to the flow direction of the liquid.

[0068] In some embodiments of this application, the second housing has a square cross-section and openings at both ends;

[0069] The screen is connected to the inner wall of the second housing and is perpendicular to the axis of the second housing;

[0070] The second housing is installed inside the cavity of the U-shaped frame, and the openings at both ends of the second housing are respectively connected to the buffer bag and the cavity of the U-shaped frame.

[0071] During low-frequency vibration, the aperture of screen 42 automatically adjusts to its maximum, allowing the liquid to flow rapidly and generate high damping force, thus preventing excessive damping and energy accumulation. Sphere 6, due to inertia, lags behind the liquid flow, increasing the liquid shear resistance and enhancing the damping effect.

[0072] During high-frequency vibration, the screen 42 deforms, limiting the liquid flow rate, while the sphere 6 intensifies turbulence due to inertial motion. Together, they enhance the high-frequency damping efficiency.

[0073] It should be noted that the generation of inertial force in this application can be understood as: the inertia of the sphere 6 itself attempts to maintain its original static state, which is opposite to the vibration direction of the liquid in the cavity. For example, when the liquid flows to the right, the sphere 6 shifts to the left due to inertia, forming a shear force opposite to the vibration direction.

[0074] The increased liquid shear resistance can be understood as follows: the offset of sphere 6 causes the liquid to form eddies and turbulence in the cavity, which significantly increases the liquid flow resistance (shear stress) to form damping.

[0075] In some embodiments of this application, the number of screens is two or more, and the two or more screens are arranged in parallel. In some embodiments, the number of screens is 3-5.

[0076] In some embodiments of this application, the aperture of the two or more screens decreases sequentially along the direction from the end of the frequency regulating element that communicates with the buffer bladder to the end of the frequency regulating element that communicates with the cavity of the elastic limiting frame.

[0077] Multiple screens 42 are arranged in parallel, which increases the level and precision of liquid flow regulation. Different screens 42 can screen and regulate the liquid multiple times according to their own characteristics. When the liquid passes through multiple parallel screens 42, each screen 42 can screen different components or liquids with different flow rates, and control the liquid flow more precisely to adapt to vibrations of different frequencies.

[0078] The aperture of the multiple screens 42 decreases sequentially from the connected part to the farthest part.

[0079] The system consists of multiple screens 42 to accommodate both low-frequency and high-frequency vibrations.

[0080] During low-frequency vibration, the screen 42 opens (the aperture automatically adjusts to the maximum state), enhancing damping. The aperture adjustment mechanism of the screen 42 is as follows: Under low-frequency vibration, the screen 42 has lower vibration energy and smaller elastic deformation, resulting in a larger passage space and allowing liquid to pass through.

[0081] When the vibration frequency exceeds the natural frequency of the screen 42, the screen 42 undergoes elastic deformation due to high-frequency vibration, reducing the effective liquid passage space and thus reducing the actual liquid throughput. For example, when a filter screen is perpendicular to the passing water, the filtration capacity is the largest; when it is tilted, the actual filtration capacity is reduced.

[0082] In some embodiments of this application, the screen includes a screen body and a screen frame, wherein the screen body is made of rubber and the screen frame is made of nickel-titanium shape memory alloy.

[0083] Example 1

[0084] like Figures 1 to 6 As shown in the embodiment of this application, a clamping device for a laser amplifier includes a U-shaped frame 1, a separator 2, a buffer bladder 3, and a frequency modulation component 4.

[0085] Two U-shaped frames 1 are symmetrically arranged and joined together to form a limiting frame that limits the laser amplifier 5; one of the limiting frames is set at each end of the laser amplifier.

[0086] A laser amplifier 5 is placed inside the U-shaped frame 1. The U-shaped frame 1 is connected to a lifting mechanism 8 via a bracket 7. The lifting mechanism 8 is an X-shaped lifting platform, which is existing technology and will not be described in detail here.

[0087] The bracket 7 is connected to two stop bars 9 that limit the length of the laser amplifier 5, and the stop bars 9 are symmetrically arranged at the beginning and end of the laser amplifier 5.

[0088] The U-shaped frame 1 has a groove 101 on its inner circumference, which increases friction.

[0089] The interior of the groove 101 has protrusions (not shown in the figure);

[0090] The protrusions inside the groove 101 contact the surface of the laser amplifier 5 when the laser amplifier 5 is placed, increasing the friction between the laser amplifier 5 and the groove 101. This can prevent the laser amplifier 5 from shifting within the U-shaped frame 1, and the laser amplifier 5 can maintain a stable installation state even in a vibration environment.

[0091] The U-shaped frame 1 has an internal cavity filled with liquid. The cavity is divided into multiple sub-chambers by a partition 2, and adjacent sub-chambers are connected. Each sub-chamber has a sphere 6 inside. When subjected to vibration, the inertial motion of the sphere 6 changes the resistance to liquid flow, thereby dissipating vibration energy.

[0092] The liquid is an aqueous solution of ethylene glycol.

[0093] The U-shaped frame 1 is a rubber frame. When it limits the laser amplifier 5, the two U-shaped frames 1 are fixedly connected to form a limiting frame. Since it contains liquid, it can conduct heat to the laser amplifier 5 to absorb its heat. As the liquid temperature rises, the clamping effect of the U-shaped frame 1 on the laser amplifier 5 is increased.

[0094] The buffer bladder 3 is connected to the U-shaped frame 1 to relieve pressure when the U-shaped frame 1 is compressed;

[0095] The frequency regulating component 4 adjusts the flow rate at the connection between the U-shaped frame 1 and the buffer bladder 3 according to the vibration frequency, and works with the sphere 6 to form liquid damping for self-adaptation.

[0096] Two U-shaped frames 1 are joined together to form a limiting frame, with a groove 101 inside for placing the laser amplifier 5, so as to install and fix the laser amplifier 5. The cavity inside the U-shaped frame 1 is filled with liquid and divided into multiple connected sub-chambers by the separator 2. When the ball 6 in the sub-chamber vibrates, it moves due to inertia, changing the liquid flow resistance. For example, when external vibration is transmitted to the U-shaped frame 1, the ball 6 will roll in the opposite direction of vibration or in other directions. During the movement, it interacts with the liquid, consumes vibration energy, realizes the dissipation of vibration energy, and reduces the impact of vibration on the laser amplifier 5. The buffer bladder 3 is connected to the U-shaped frame 1. When the U-shaped frame 1 is compressed, the liquid can flow into the buffer bladder 3 to relieve pressure and prevent the U-shaped frame 1 from being damaged due to excessive pressure, thus ensuring structural stability. The frequency regulating component 4 can adjust the flow rate at the connection between the U-shaped frame 1 and the buffer bladder 3 according to the vibration frequency. Together with the ball 6, it forms liquid damping, enhances the adaptability to vibrations of different frequencies, and better reduces vibration interference.

[0097] like Figure 5 As shown, the separator 2 includes an inner plate 21 and an outer plate 22 surrounding the outer periphery of the inner plate. The outer plate 22 is made of rubber and is connected to the inner wall of the cavity of the U-shaped frame. The inner plate 21 has at least one first flow hole 211 for connecting the sub-chambers on both sides of the separator 2.

[0098] like Figure 5 As shown, both sides of the inner plate 21 are provided with swirling grooves 212, and the tail end of the swirling grooves 212 is connected to the first flow hole 211.

[0099] The inner hole 21 has swirl grooves 212 on both sides, and the tail end is connected to the first flow hole 211. There are 6 swirl grooves 212, and the 6 swirl grooves 212 are evenly distributed.

[0100] The depth of the swirl channel 212 increases sequentially from the first end to the last end.

[0101] like Figures 6 to 8As shown, the frequency regulating component 4 includes a fixed plate 43, a first housing 44, axial flow blades 45, and a rotating plate 46. The rotating plate 46 is made of magnetic material. The first housing has a circular cross-section with openings at both ends. The first housing 44 is installed inside the cavity of the U-shaped frame and located at the connection between the buffer bladder 3 and the U-shaped frame 1. The fixed plate 43 is installed inside the first housing 44 and is perpendicular to the axis of the first housing. The rotating plate 46 is rotatably installed inside the first housing 44, located below the fixed plate 43, and is also perpendicular to the axis of the first housing. The rotating plate 46 is fixedly connected to the axial flow blades 45 via a rotating shaft. The moving plate rotates with the axial flow blade 45. The fixed plate 43 has multiple second flow holes 412, and the rotating plate 46 has multiple third flow holes 413. The second and third flow holes 412 and 413 are the same size and number, and their positions can overlap. A hollow tube 47 is installed inside each second flow hole 412. One end of the hollow tube 47 is connected to one end of a spring 48, and the other end of the spring 48 is connected to the inner wall of the second flow hole 412. A magnetic block 49 is installed on the outer wall of the hollow tube 47. A strip magnetic sheet 410 with the same magnetic properties as the magnetic block 49 is installed on the rotating shaft connected to the axial flow blade 45. Figure 8 As shown, Figure 8 (This is a bottom view of the rotating plate in the frequency regulating component). An electromagnet 411 is installed inside the first housing 44.

[0102] During low-frequency vibration, the electromagnet 411 is energized to limit the position of the rotating plate 46. At this time, the third flow hole 413 on the rotating plate 46 corresponds to the position of the second flow hole 412 on the fixed plate 43. This facilitates liquid flow, and the liquid can quickly flow into the buffer bladder 3 through the large-area passage to relieve pressure, avoiding excessive damping and energy accumulation. The energy is mainly dissipated by the inertial motion of the sphere 6, and the frequency regulating component 4 only provides a low-damping passage to ensure flexible response under low-frequency vibration.

[0103] During high-frequency vibration, the liquid generates high-speed, low-flow-rate flow due to the high-frequency vibration. After forming turbulence through the swirl channel 212 of the separator 2, it enters the first housing 44. When high-frequency vibration is detected (a vibration sensor can be used for detection), the electromagnet 411 releases its adsorption limit on the rotating plate 46. The high-speed liquid impacts the axial flow blade 45, causing it to drive the rotating plate 46 to rotate significantly. The overlapping area of ​​the second flow hole 412 and the third flow hole 413 decreases or even partially closes. The liquid needs to flow through a narrow gap or the gap between the hollow tube 47 and the third flow hole 413. The flow resistance increases dramatically, and the sphere 6 intensifies the turbulence, jointly improving the high-frequency damping efficiency. At the same time, when the axial flow blade 45 rotates, it drives the strip magnetic sheet 410 to rotate, which acts on the hollow tube 47. The hollow tube 47 moves upward to push out the blockage at the second flow hole 412, facilitating the passage of liquid. After the high-frequency vibration ends, a light sensor is installed inside the first housing 44 to detect whether the flow hole is aligned. After alignment, the electromagnet 411 adsorbs the rotating plate 46 to limit its movement.

[0104] Example 2

[0105] The difference from Example 1 is that:

[0106] like Figure 10 As shown, the frequency regulating component 4 includes a second housing 41 and a screen 42. The second housing has a square cross-section and openings at both ends. The second housing 41 is installed in the cavity of the U-shaped frame and is located at the connection between the buffer bladder 3 and the cavity of the U-shaped frame. The screen 42 is installed inside the second housing 41 and is perpendicular to the flow direction of the liquid.

[0107] It should be noted that one side of the second housing 41 extends to the outside of the cavity and is flush with the outer peripheral surface of the second housing 41.

[0108] The second housing 41 of the frequency regulating component 4 is installed inside the cavity of the U-shaped frame, located at the connection between the buffer bladder 3 and the U-shaped frame 1, and serves to fix the screen 42. The screen 42 is installed on the second housing 41. Vibrations of different frequencies will cause different flow velocities and pressure changes in the liquid inside the cavity of the U-shaped frame. The screen 42 adjusts the liquid flow rate according to these changes, so that the frequency regulating component 4 and the ball 6 are linked, with both high-frequency vibration coordination and low-frequency vibration coordination.

[0109] During high-frequency vibration, the turbulence of the metal ball is enhanced. Due to inertia, the ball 6 responds rapidly during high-frequency vibration, which hinders the flow of liquid and forms high shear resistance. The amount of liquid passing through the screen 42 is reduced, which increases the shear resistance of the liquid flow and inhibits the transmission of high-frequency vibration energy.

[0110] During low-frequency vibration, the screen 42 opens to reduce liquid resistance, and the sphere 6 moves smoothly to avoid excessive energy consumption.

[0111] Furthermore, there are multiple screens 42, which are arranged in parallel.

[0112] Multiple screens 42 are arranged in parallel, which increases the level and precision of liquid flow regulation. Different screens 42 can screen and regulate the liquid multiple times according to their own characteristics. When the liquid passes through multiple parallel screens 42, each screen 42 can screen different components or liquids with different flow rates, and control the liquid flow more precisely to adapt to vibrations of different frequencies.

[0113] The aperture of the multiple screens 42 decreases sequentially from the connected part to the farthest part.

[0114] The system consists of multiple screens 42 to accommodate both low-frequency and high-frequency vibrations.

[0115] During low-frequency vibration, the screen 42 opens, enhancing damping. The aperture adjustment mechanism of the screen 42 is as follows: Under low-frequency vibration, the screen 42 has lower vibration energy and smaller elastic deformation, resulting in a larger passage space and allowing liquid to pass through.

[0116] When the vibration frequency exceeds the natural frequency of the screen 42, the screen 42 undergoes elastic deformation due to high-frequency vibration, reducing the effective liquid passage space and thus reducing the actual liquid throughput. For example, when a filter screen is perpendicular to the passing water, the filtration capacity is the largest; when it is tilted, the actual filtration capacity is reduced.

[0117] The screen 42 is composed of a rubber mesh body and nickel-titanium shape memory alloy strips embedded on the four sides of the rubber mesh body.

[0118] In use, two U-shaped frames 1 are symmetrically connected to form a limiting frame, which is fitted onto the outer periphery of the laser amplifier 5. The protrusions in the groove 101 increase the friction between the laser amplifier 5 and the laser amplifier 5, reducing the displacement of the laser amplifier 5 when vibrating. At the same time, the U-shaped frame 1 is made of rubber and contains liquid, which not only limits the laser amplifier 5 but also absorbs the heat of the laser amplifier 5. When the temperature rises, it enhances the clamping effect on the laser amplifier 5.

[0119] The internal cavity of the U-shaped frame 1 is divided into multiple interconnected sub-chambers by the partition 2. Each sub-chamber contains a sphere 6. When external vibrations are transmitted to the U-shaped frame 1, the sphere 6 moves due to inertia, changing the resistance to liquid flow and consuming vibration energy. The inner plate 21 of the partition 2 is connected to the cavity through the outer rubber plate 22, which buffers the force. The first flow hole 211 on the inner plate 21 allows the liquid to flow between the sub-chambers. In addition, the tail ends of the swirling grooves 212 on both sides of the inner plate 21 are connected to the flow holes 211. Multiple swirling grooves 212 with equal spacing and increasing depth cause the liquid to swirl, increasing the friction with the sphere 6 and the groove walls, further dissipating vibration energy.

[0120] The second housing 41 of the frequency regulating component 4 is located at the cavity connecting the buffer bladder 3 and the U-shaped frame, and a fixed screen 42 is installed. Multiple screens 42 arranged in parallel with their aperture decreasing sequentially from the connection point to the distance from the connection point are used to regulate the liquid flow rate according to the vibration frequency. During high-frequency vibration, the screen 42 deforms to restrict the liquid flow, and the sphere 6 intensifies turbulence, thus improving the high-frequency damping efficiency. During low-frequency vibration, the screen 42 opens to reduce liquid resistance, and the sphere 6 moves smoothly to avoid excessive energy consumption.

[0121] The buffer bladder 3 is connected to the cavity of the U-shaped frame. When the cavity of the U-shaped frame is pressurized, liquid flows into the buffer bladder 3 to relieve pressure and ensure structural stability.
