Description

Technical Field

[0001] The present application relates to the field of seismic exploration technology, and in particular to a solid physics simulation observation device and system. Background Art

[0002] Seismic physics simulation experiments are used to simulate the propagation laws of field seismic wave fields. With the development of actual field seismic exploration from longitudinal wave exploration to joint longitudinal and transverse wave exploration, seismic physics simulation experiments need to be able to simulate the propagation laws of various complex wave fields such as longitudinal waves, transverse waves, and conversion waves. At present, a method of directly hard-contact simulation acquisition on the surface of a solid model is used to simulate the propagation laws of field seismic wave fields.

[0003] The existing physical model solid surface acquisition technology realizes the solid surface acquisition of the physical model through a dedicated solid model acquisition device and a solid acquisition transducer (ultrasonic transducer) matched with the device. However, this solid model acquisition device has the following problems: 1. The core and shell of the ultrasonic transducer are professionally customized, with poor versatility, and high production and maintenance costs of the whole device; 2. The integrated design of the force-adding device and the ultrasonic transducer makes the device larger in lateral dimension, and the minimum longitudinal offset distance of the simulated acquisition is larger, resulting in the lack of near-offset reflection information in the simulation experimental results. For example, for a solid model acquisition device with an ultrasonic transducer diameter of 10mm and a lateral dimension of more than 30mm, the minimum center distance of the excitation receiving point is greater than 35mm. When performing a 1:10000 scale earthquake physical simulation, the 0-350m offset reflection information will be missing; 3. During the lifting and lowering process of the probe, the spring squeezes the ultrasonic transducer to produce a rotational movement, resulting in the difficulty in accurately controlling the polarization direction of the shear wave acquisition.

[0031] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0032] As mentioned above, the existing physical model solid surface acquisition technology uses a special solid model acquisition device, the transducer and the force device of the device are integrated. In order to improve the stability of the device, the outer part of the transducer is a cylindrical structure, and the probe is located below the cylindrical structure. When the device performs seismic wave field acquisition, the transducer moves downward under the drive of the force device, so that the probe contacts the solid surface of the seismic wave field to be collected. This device has the following problems: 1. The core and shell of the ultrasonic transducer are professionally customized, with poor versatility, and high production and maintenance costs for the entire device; 2. The integrated design of the force device and the ultrasonic transducer makes the device larger in lateral dimensions, and the minimum longitudinal offset distance of the simulated acquisition is larger, resulting in the lack of near-offset reflection information in the simulation experimental results; 3. During the lifting process of the probe, the spring squeezes the ultrasonic transducer to produce rotational movement, which makes it difficult to accurately control the polarization direction of the shear wave acquisition.

[0033] In order to solve the above problems, the present application provides a solid physics simulation observation device, which uses a detachable clamping assembly to fix the transducer assembly, and can realize the combination of transducer assemblies of different models and clamping assemblies, so that the device has stronger versatility; by fixing the first end of the spring to the fixing part of the transducer assembly, and fixing the second end of the spring to the clamping assembly, the polarization direction of the transducer assembly caused by the torsional movement of the transducer assembly when the spring is squeezed can be avoided, thereby realizing more accurate and reliable acquisition of the seismic wave field; in addition, the clamping part of the transducer assembly (that is, the first clamping part and the second clamping part after fixed connection) adopts a rectangular structure, and the direction of the longer side of the rectangular parallelepiped close to the spring is used as the force direction of the clamping assembly, and the direction of the shorter side of the rectangular parallelepiped close to the spring is used as the propagation direction of the elastic wave, which can reduce the lateral size of the device, collect more near-offset moment signals, and improve the collection of near-offset moment effective signals.

[0034] The solid state physics simulation observation device in the embodiment of the present application will be introduced below with reference to the accompanying drawings.

[0035] Figure 1 Shown is a schematic diagram of a clamping assembly provided in an embodiment of the present application. Figure 1 a and b in the figure are schematic diagrams of the clamping assembly at different viewing angles.

[0036] Figure 2 Shown is a schematic diagram of a solid physics simulation observation device provided in an embodiment of the present application.

[0037] like Figure 1 and Figure 2 As shown, the solid physics simulation observation device may include: a clamping component 10 and a transducer component 20 .

[0038] The clamping assembly 10 includes a first clamping portion 101 and a second clamping portion 102, wherein the first clamping portion 101 includes a first groove 1011, and the second clamping portion 102 includes a second groove 1021. When the first clamping portion 101 and the second clamping portion 102 are fixedly connected, the first groove 1011 and the second groove 1021 are combined into a through hole 103.

[0039] One end of the transducer assembly 20 is provided with a fixing portion, and a spring 30 is installed in the middle of the transducer assembly 20. Figure 2 The fixing sleeve 201) is used to fix the first end of the spring 30 close to the fixing portion.

[0040] It can be understood that the transducer assembly 20 can be a longitudinal wave excitation / reception transducer and a transverse wave excitation / reception transducer that can meet the needs of earthquake physics simulation experiments, and can be used for longitudinal and transverse wave excitation / reception. The lower part of the transducer assembly 20 can be used to contact the surface of a solid model (i.e., a solid model to be observed for seismic wave fields) and realize the excitation and / or reception of longitudinal and transverse waves.

[0041] The end of the transducer component 20 away from the fixed part passes through a through hole 103 formed by the fixed connection between the first clamping part 101 and the second clamping part 102. The second end of the spring 30 close to the clamping component 20 is fixed to the clamping component 10. The clamping component 10 moves vertically downward along the through hole 103 to compress the spring 30, thereby realizing the acquisition of solid surface elastic waves.

[0042] It can be understood that the first clamping part 101 and the second clamping part 102 of the clamping assembly 10 form a detachable structure. By controlling whether the first clamping part 101 and the second clamping part 102 are connected or not, the installation and disassembly of the transducer assembly 20 can be achieved. That is, by fixedly connecting the first clamping part 101 and the second clamping part 102, the transducer assembly 20 can be fixedly installed on the clamping assembly 10. By disassembling the fixedly connected first clamping part 101 and the second clamping part 102, the transducer assembly 20 can be removed from the clamping assembly 10. At this time, other types of transducer assemblies can be replaced and installed in the first groove 1011 of the first clamping part 101, and the first clamping part 101 and the second clamping part 102 are fixedly connected to achieve the replacement of the transducer assembly model. Through the detachable structure of the first clamping part 101 and the second clamping part 102, the combination of the clamping assembly and transducer assemblies of different models can be achieved, so that the solid physics simulation observation equipment in this application has stronger versatility.

[0043] It is understood that the second end of the spring 30 can be fixed to a surface of the clamping assembly 10 close to one end of the spring, for example Figure 1The bottom surface of the clamping assembly 10 is fixed to the periphery of the through hole on the bottom surface of the clamping assembly, and then the clamping assembly 10 can be controlled to move vertically downward so that the transducer assembly 20 contacts the surface of the solid model. When the transducer assembly 20 contacts the solid surface, the clamping assembly 10 is continuously controlled to move vertically downward so that the spring 30 is compressed. When the spring 30 is compressed, the spring is respectively fixed to the transducer assembly and the clamping assembly, thereby avoiding torsional movement of the spring.

[0044] It can be understood that by fixing the two ends of the spring 30 respectively through the fixing part of the transducer assembly 20 and the clamping assembly 10, the torsional movement of the spring 30 when subjected to force can be effectively controlled, thereby avoiding the change in the polarization direction of the transducer assembly when the spring 30 undergoes torsional movement, and thus the solid physics simulation observation equipment can be accurately controlled to simulate the excitation and reception of the shear wave components in the seismic wave field, including the shear wave SV component (vertically polarized shear wave) and the shear wave SH component (horizontally polarized shear wave), thereby ensuring the accurate and reliable acquisition of the elastic wave components, wherein the shear wave SV component can be understood as the component of the shear wave in the vertical polarization direction, and the shear wave SH component can be understood as the component of the shear wave in the horizontal polarization direction.

[0045] It can be understood that the first groove 1011 of the first clamping portion 101 and the second groove 1021 of the second clamping portion 102 can form a through hole 103 when the first clamping portion 101 and the second clamping portion 102 are fixedly connected, wherein the through hole 103 can be used to accommodate the energy displacing component 20, and the through hole 103 is used to accommodate one end of the energy displacing component 20 away from the fixed portion.

[0046] It can be understood that the clamping assembly 10 can be used to clamp and fix the transducer assembly 20, and the transducer assembly 20, the spring 30, and the control device for controlling the vertical movement of the clamping assembly 10 and the transducer assembly and compressing the spring can be connected into an organic whole to achieve the excitation and collection of elastic waves on the surface of the solid model to simulate the seismic wave field.

[0047] In some embodiments, the through hole 103 may be cylindrical, and the diameter of the cylindrical through hole remains the same along the through hole direction. In other embodiments, the through hole may be a multi-section cylindrical shape, and the diameter of each section of the cylinder may be different.

[0048] It can be understood that the shape of the through hole 103 formed by the first groove 1011 of the first clamping part 101 and the second groove 1021 of the second clamping part 102 can match the shape of the transducer component 20, and then the shapes of the first groove 1011 and the second groove 1021 can match the outer contour of part of the transducer component 20. For example, when the outer contour of the transducer component 20 is cylindrical, the through hole 103 matches the shape of the transducer component 20, and is cylindrical, and the first groove 1011 and the second groove 1021 can be semicircular arc grooves of the same size and shape; when the outer contour of the transducer component 20 is a cylindrical shape with multiple sections of different diameters, the through hole 103 can be a cylindrical shape with multiple sections that can meet the transducer component to move back and forth in the through hole, and then the shapes of the first groove 1011 and the second groove 1021 can be the same as the semicircular arc grooves of the same size with multiple sections of different diameters.

[0049] In some embodiments, the spring 30 may be a general steel spring, the inner diameter of the spring 30 may match the diameter of the transducer assembly 20, and the length and wire diameter of the spring 30 may be determined according to the main body size of the transducer assembly 20, the coupling effect of the solid physics simulation observation device on the solid model acquisition stress, the magnitude of the spring stress, and other factors. It can be understood that when the solid physics simulation observation device performs solid acquisition on the solid model, its signal acquisition quality is positively correlated with the coupling pressure applied by the transducer assembly 20 on the surface of the solid model. When the coupling pressure is greater than a certain value, the signal acquisition quality of the solid model surface is basically stable. Therefore, the maximum deformation stress of the spring 30 may be greater than the optimal coupling stress of the transducer assembly 20 squeezing the surface of the solid model to ensure the basic stability of the signal acquisition quality.

[0050] In some embodiments, the first clamping portion 101 and the second clamping portion 102 may be provided with screw holes with matching positions, and the first clamping portion 101 and the second clamping portion 102 may be fixedly connected by screws and spliced ​​into a complete structure to clamp transducer components of different models.

[0051] In some embodiments, one end where the first clamping portion 101 and the second clamping portion 102 are connected and fitted may include a mortise and tenon structure, through which the first clamping portion 101 and the second clamping portion 102 can be fixedly connected and spliced ​​into a complete structure to clamp transducer components of different models.

[0052] In some embodiments, at least three protruding points 104 are provided along the periphery of the through hole 103 at one end of the first clamping portion 101 and the second clamping portion 102 close to the spring 30 , and the at least three protruding points 104 are used to fix the second end of the spring 30 close to the clamping assembly 10 .

[0053] It can be understood that at least three protruding points 104 can fix the second end of the spring 30 to one end of the clamping assembly 10 after the first clamping portion 101 and the second clamping portion 102 are fixedly connected, and the first end of the spring 30 is fixed by the fixing portion of the transducer assembly 20, so that the spring 30 can be fixed to prevent it from twisting when subjected to force, thereby affecting the polarization direction of the transducer assembly 20. The at least three protruding points 104 can be evenly distributed or non-uniformly distributed around the through hole 103. The spring 30 can be fixed by at least three protruding points 104, and the number and position of the protruding points can be adjusted based on demand or actual application scenarios. For example, three protruding points can be set at equal intervals, four protruding points can be set at equal intervals, etc.

[0054] In some embodiments, four wedge-shaped protrusions 104 are evenly spaced along the circumference of the through hole at one end of the first clamping portion and the second clamping portion close to the spring, and the four wedge-shaped protrusions are used to fix the second end of the spring close to the clamping assembly.

[0055] It can be understood that the wedge-shaped protrusion can be used to fix the second end of the spring 30. The four wedge-shaped protrusions are arranged at equal intervals, and the angle interval between each other is 90 degrees. When the solid collection compression spring 30 of the transducer component 20 is subjected to force, the top of the spring 30 (i.e., the second end) is fixed by the protrusion, which suppresses the lateral torsional movement of the compressed spring 30, ensuring that the collection polarization orientation of the transducer component 20 does not change. In addition, based on the four wedge-shaped protrusions arranged at equal intervals, the polarization direction of the transducer component 20 can be driven to rotate 90 degrees by rotating the spring 30 to match the wedge-shaped protrusions, so as to accurately control the excitation and reception of the two mutually perpendicular polarization directions of the shear wave transducer component 20.

[0056] It can be understood that by setting four wedge-shaped protrusions, and the angle interval between two wedge-shaped protrusions is 90 degrees, the polarization direction of the transducer assembly can be precisely controlled, and then by changing the excitation of the corresponding shear wave SV component, shear wave SH component and longitudinal wave component, and simultaneously changing the reception of the corresponding shear wave SV component, shear wave SH component and longitudinal wave component, the solid model elastic wave nine-component simulation acquisition can be realized. The elastic wave nine components may include: shear wave SV component excitation / shear wave SV component reception, shear wave SV component excitation / shear wave SH component reception, shear wave SV component excitation / longitudinal wave reception, shear wave SH component excitation / shear wave SH component reception, shear wave SH component excitation / shear wave SV component reception, shear wave SH component excitation / shear wave SH component reception, shear wave SH component excitation / shear wave SV component reception, shear wave SH component excitation / longitudinal wave reception, longitudinal wave excitation / longitudinal wave reception, longitudinal wave excitation / shear wave SV component reception, and longitudinal wave excitation / shear wave SH component reception.

[0057] In some embodiments, the through hole includes a first accommodating cavity 1031 and a second accommodating cavity 1032, wherein the first accommodating cavity 1031 is located at the first end of the clamping assembly 10 close to the spring 30, and the second accommodating cavity 1032 is located at the second end of the clamping assembly 10 away from the spring 30, and the diameter of the first accommodating cavity 1031 is smaller than the diameter of the second accommodating cavity 1032.

[0058] It can be understood that the lengths of the first accommodating cavity 1031 and the second accommodating cavity 1032 can be determined based on the maximum elastic deformation of the spring, the size of the transducer component 20, etc., and the diameters of the first accommodating cavity 1031 and the second accommodating cavity 1032 can be determined based on the diameter of the transducer component 20.

[0059] In some embodiments, the diameter of the first accommodating cavity 1031 may match the diameter of the main body of the transducer assembly 20 , and the diameter of the second accommodating cavity 1032 may be greater than the diameter of the transducer assembly 20 .

[0060] In some embodiments, the end of the transducer component 20 away from the fixed portion may include a cylindrical segment with a larger diameter, for example, which may be fixed by a sleeve or integrally formed with the main body of the transducer component. Furthermore, the diameter of the first accommodating cavity 1031 may match the main body of the transducer component 20, that is, the portion between the cylindrical segment and the raised portion, so as to fix the transducer component and control the vertical downward movement distance of the transducer component 20 to prevent the transducer component 20 from detaching from the bottom of the clamping component 10 and affecting the excitation and reception of the signal. The diameter of the second accommodating cavity 1032 may match the diameter of the cylindrical segment to realize the back and forth movement of the cylindrical segment in the through hole.

[0061] In some embodiments, when the spring is not deformed by force, the distance between the cylindrical section and the spring can match the length of the first accommodating cavity 1031, or can be greater than the length of the first accommodating cavity 1031. However, when the distance between the cylindrical section and the spring is greater than the length of the first accommodating cavity 1031, it is necessary to satisfy that: the distance between the end surface of the cylindrical section away from the spring 30 and the top of the second accommodating cavity 1032 is less than the maximum deformation of the spring 30. It can be understood that when the clamping assembly 10 is subjected to force, the transducer assembly 20 and the clamping assembly 10 will move relative to each other, and the spring is compressed at this time. When the spring 30 is subjected to force and produces the maximum elastic deformation, at least part of the cylindrical section needs to be still located in the through hole to avoid the transducer assembly 20 from moving laterally in the through hole 103 due to the cylindrical section being separated from the through hole 103, so that the polarization direction of the transducer assembly 20 changes, affecting the accurate simulation acquisition of elastic waves of the simulated seismic wave field.

[0062] In some embodiments, the transducer assembly 20 may be a general transducer of a cylindrical structure, the length of the cylinder of the transducer assembly 20 may be greater than 50 mm, and the diameter of the main part of the cylinder may be no greater than 14 mm. The general transducer types may include: a "│" type transducer with the same diameter at the top and bottom of the cylinder, a "T" type transducer with a large diameter at the top and a small diameter at the bottom (the bottom of the transducer assembly is its main part), and a "⊥" type transducer with a small diameter at the top and a large diameter at the bottom (the top of the transducer assembly is its main part).

[0063] In some embodiments, when the transducer assembly is a “│” type transducer or a “T” type transducer, the fixing portion of the transducer assembly 20 may be a fixing sleeve for fixing the first end of the spring 30 .

[0064] It can be understood that the fixing portion can be integrally formed with the transducer assembly, or can be formed by other circular tube structures, as long as the first end of the spring 30 can be effectively fixed, and the present application does not impose any limitation on this.

[0065] In some embodiments, the fixing portion provided on the transducer assembly 20 is an annular protrusion, and a fixing sleeve (for example, Figure 2 The fixing sleeve 202 in the second accommodating cavity 1031 is provided, and the outer diameter of the fixing sleeve matches the diameter of the second accommodating cavity 1031, and the outer diameter of the end of the transducer assembly 20 away from the fixing portion matches the diameter of the first accommodating cavity 1031. It can be understood that the fixing portion and the transducer assembly 20 are integrally formed. In other embodiments, the fixing portion can also be a cylindrical segment, that is, the transducer assembly 20 is a "⊥"-shaped transducer, which is not limited in the present application.

[0066] The distance between the fixing sleeve and the fixing portion may be greater than or equal to the sum of the lengths of the spring 30 and the first accommodating cavity 1031 , and when the spring 30 is subjected to force and produces maximum elastic deformation, at least part of the fixing sleeve is located in the second accommodating cavity 1032 .

[0067] It can be understood that when the spring 30 is subjected to force and produces maximum elastic deformation, at least part of the fixed sleeve is located in the second accommodating cavity 1032, which can prevent the fixed sleeve from detaching from the through hole 103, causing the transducer assembly 20 to move laterally in the through hole 103, resulting in a change in the polarization direction of the transducer assembly 20, affecting the accurate simulation and acquisition of elastic waves of the simulated seismic wave field.

[0068] It can be understood that the spring 30 can be installed in the middle of the transducer assembly 20, and a fixed sleeve can be added to the upper part of the transducer assembly 20. The distance between the fixed sleeve and the fixed part can be greater than or equal to the sum of the lengths of the spring 30 and the first accommodating cavity 1031, and when the spring produces the maximum elastic deformation, part of the fixed sleeve can still be located in the second accommodating cavity 1032, so that the spring 30 can be fixed between the fixed part and the clamping assembly, and will not undergo torsional movement due to force compression; and the vertical downward movement distance of the transducer assembly 20 is controlled to prevent the transducer assembly 20 from detaching from the clamping assembly 10, affecting the excitation and reception of the signal; in addition, when the spring 30 is subjected to force to produce the maximum elastic deformation, at least part of the fixed sleeve is still located in the second accommodating cavity 1032, so as to prevent the transducer assembly 20 from moving laterally in the through hole 103 due to the fixed sleeve detaching from the second accommodating cavity 1032, causing the polarization direction of the transducer assembly 20 to change, affecting the accurate simulation acquisition of the elastic waves of the simulated seismic wave field.

[0069] In some embodiments, the transducer assembly 20 includes a first transducer portion and a second transducer portion, and the fixed portion of the transducer assembly is a fixed sleeve (eg, Figure 2 The outer diameter of the second transducer part matches the diameter of the second accommodating cavity 1032, and the outer diameter of the first transducer part of the transducer assembly 20 matches the diameter of the first accommodating cavity 1031. It can be understood that the first transducer part and the second transducer part are an integrally formed structure. For example, the transducer assembly can be a "T"-shaped transducer, the first transducer part can be a main body part with a smaller diameter of the "T"-shaped transducer, and the second transducer part can be an upper part with a larger diameter of the "T"-shaped transducer. The distance between the fixed sleeve and the second transducer part is greater than or equal to the sum of the lengths of the spring 30 and the first accommodating cavity 1031, and when the spring 30 is subjected to force to produce maximum elastic deformation, at least part of the second transducer part is located in the second accommodating cavity 1032.

[0070] In some embodiments, the fixing portion of the transducer assembly 20 is a first fixing sleeve (eg, Figure 2 The end of the transducer assembly away from the first fixed sleeve is fixedly mounted with a second fixed sleeve (eg Figure 2 The outer diameter of the second fixed sleeve matches the diameter of the second accommodating cavity, and the outer diameter of the part of the transducer assembly located between the first fixed sleeve and the second fixed sleeve matches the diameter of the first accommodating cavity. It can be understood that the transducer assembly is a "│" type transducer with the same upper and lower diameters. The spring 30 can be installed in the middle of the transducer, and the fixed sleeves (for example, Figure 2The fixing sleeve 201 and the fixing sleeve 202 are used to fix the spring and the transducer respectively.

[0071] The distance between the first fixed sleeve and the second fixed sleeve is greater than or equal to the sum of the lengths of the spring 30 and the first accommodating cavity 1031 , and when the spring is subjected to maximum elastic deformation, at least part of the second fixed sleeve is located in the second accommodating cavity.

[0072] It can be understood that the fixed sleeve fixedly installed on the first transducer part in the above-mentioned "T"-shaped transducer and the first fixed sleeve in which the fixed rod is installed at the lower part in the "│"-shaped transducer can be equivalent to the fixed part of the annular protrusion in the aforementioned embodiment, the second transducer part in the "T"-shaped transducer and the second fixed sleeve in which the fixed rod is installed at the upper part in the "│"-shaped transducer can be equivalent to the fixed sleeve installed at the end of the transducer component away from the fixed part in the aforementioned embodiment, the spring 30 can be installed in the middle of the transducer component 20, and fixing parts (such as annular protrusions or fixed sleeves) can be respectively provided at the upper and lower parts of the transducer component 20, the distance between the upper and lower fixing parts can be greater than or equal to the sum of the lengths of the spring 30 and the first accommodating cavity 1031, and when the spring generates During the maximum elastic deformation, the upper fixing component can still be located in the second accommodating cavity 1032, so that the spring 30 can be fixed between the lower fixing component and the clamping component, and will not undergo torsional movement due to compression; and the vertical downward movement distance of the transducer component 20 is controlled to prevent the transducer component 20 from being separated from the clamping component 10, affecting the excitation and reception of the signal; in addition, when the spring 30 is subjected to the maximum elastic deformation, at least part of the upper fixing component is still located in the second accommodating cavity 1032, so as to prevent the transducer component 20 from moving laterally in the through hole 103 due to the upper fixing component being separated from the second accommodating cavity 1032, causing the polarization direction of the transducer component 20 to change, affecting the accurate simulation and acquisition of elastic waves simulating the seismic wave field. In the implementation of this application, there is no restriction on the existence form of the fixing component, such as one-piece molding or fixed connection of other components, and other components that can realize the fixing of the spring and the transducer component are within the protection scope of this application.

[0073] It can be understood that the transducer component (such as a longitudinal and transverse wave excitation / receiving transducer) can install the spring 30 at its central main body position through its own structure and fixing components, and load the transducer component 20 into the through hole 103 of the clamping component 10. The transducer component 20 and the clamping component 10 can be installed as a whole through the two detachable structures of the clamping component 10 (i.e., the first clamping part 101 and the second clamping part 102), wherein the lower part of the spring 30 (i.e., the first end of the spring 30) is connected to the lower fixing part of the transducer component 20, and the upper part of the spring 30 (i.e., the second end of the spring 30) is fixed by the raised point at the bottom of the transducer component 20 clamping loading. When the upper part of the spring is fixed, the polarization direction of the transducer component transducer wave probe is adjusted to the SV / SH direction, and then the lower part of the spring and the fixing part of the lower part of the transducer component are fixed as a whole. By rotating the relative position relationship between the spring and the raised point, the horizontal polarization direction of the transducer wave transducer component can achieve a change of 90 degrees each time.

[0074] In some embodiments, a fixed sleeve installed on the transducer assembly, such as a fixed sleeve installed on the upper and / or lower part of the transducer assembly, can be a circular tubular structure, whose length can be controlled at 5-10 mm, whose inner diameter matches the main body size of the transducer assembly, and whose outer diameter can be 2-3 mm larger than the main body diameter of the transducer assembly. The fixed sleeve can be tightly fitted with the surface of the transducer assembly by bonding, threads or screws to achieve a fixed connection with the transducer assembly.

[0075] In some embodiments, the solid physics simulation observation device also includes a device fixing part 40, and the device fixing part 40 is provided with a fixing slot 401; the device fixing part 40 is located at an end of the first clamping part 101 away from the transducer component 20, and the device fixing part 40 is fixedly connected or integrally formed with the first clamping part 101; the fixing slot 401 is used to fix the clamping component 20 to a control device, and the control device is used to control the vertical downward movement of the clamping component 20.

[0076] It can be understood that the device fixing part 40 is used to fix the clamping assembly 10 of the clamping transducer assembly 20 to the control device, and the fixing slot 401 of the device fixing part 40 can match the component shape of the control device used to fix the device fixing part 40 to ensure that the device clamping assembly 10 can be loaded in the same position of the control device each time; the fixing slot 401 can be installed on the control device by a lock.

[0077] In some embodiments, the control device can be a positioning machine tool, and two gantry-type three-dimensional coordinate measuring machines can be selected to achieve high-precision three-dimensional spatial positioning of the transducer component 20. The three-dimensional spatial positioning error of the gantry-type three-dimensional coordinate measuring machine is less than 0.01 mm, and its measurement range is larger than the simulated working area range of the three-dimensional solid model, and the two gantry-type three-dimensional coordinate measuring machines can have the same three-dimensional spatial measurement range.

[0078] It can be understood that through the equipment fixing part 40 and the clamping assembly 10, the transducer assembly 20, the spring 30, and the gantry-type three-coordinate measuring machine can be connected into an organic whole, thereby improving the simulation acquisition capability of the nine-component signal of the solid model elastic wave, improving the equipment positioning acquisition accuracy, improving the quality of longitudinal and transverse wave signal acquisition, improving the consistency of the collected signals between different components of the elastic wave, and improving the accurate control of the two mutually perpendicular polarization directions of the transverse wave.

[0079] In some embodiments, the first clamping portion and the second clamping portion are fixedly connected to form a rectangular parallelepiped, and the direction of the longer side of the rectangular parallelepiped close to the spring serves as the force direction of the clamping assembly, and the direction of the shorter side of the rectangular parallelepiped close to the spring serves as the propagation direction of the elastic wave.

[0080] In some embodiments, the device fixing portion 40 and the clamping assembly 10 may be an integrally formed structure, and may be a hollow cuboid, with the clamping assembly 10 located at the lower portion of the hollow cuboid. Figure 1 Specifically, the device fixing part 40 can be integrally formed with the first clamping part 101, and the second clamping part 102 is detachably connected to the first clamping part 101. The fixing groove of the device fixing part 40 can be located at the upper part of the rectangular parallelepiped and can protrude from the upper part of the rectangular parallelepiped, so as to be fixedly connected to the gantry type three-dimensional coordinate measuring machine.

[0081] Among them, the clamping assembly after fixed connection can be a rectangular parallelepiped structure, the long side direction of the structure (i.e. the direction of the longer side of the clamping assembly close to the spring) can be the main force direction of the clamping assembly, and the short side direction (i.e. the direction of the shorter side of the clamping assembly close to the spring), that is, the lateral direction of the device, can be used to clamp and fix the transducer assembly. This design can greatly reduce the lateral size of the clamping assembly. For transducer assemblies with a diameter of less than 14 mm, the lateral size of the clamping assembly can be reduced to 18 mm. The interior of the rectangular parallelepiped is hollow in the vertical direction, and the hollow is a through hole, which is divided into a lower accommodating cavity (i.e. the first accommodating cavity) and an upper accommodating cavity (i.e. the second accommodating cavity) of different diameters, wherein the diameter of the upper accommodating cavity matches the outer diameter of the upper fixing part of the transducer assembly, and the diameter of the lower accommodating cavity matches the outer diameter of the transducer assembly. This design can help the clamping assembly to complete the fixation of the longitudinal and transverse wave excitation / receiving transducer assembly and suppress the lateral shaking of the transducer assembly during the up and down movement. Among them, the rectangular structure is of detachable design, which can be cut into two detachable structures along the center line of the through hole. The two half-side structures can be spliced ​​with screws or connected with mortise and tenon joints to form a complete structure, which is used to clamp transducer components of different models.

[0082] It can be understood that the design of the hollow cuboid formed by the combination of the equipment fixing portion 40 and the clamping assembly 10 can greatly reduce the lateral size of the clamping assembly while ensuring the structural strength of the clamping assembly.

[0083] In some embodiments, the component formed by the device fixing portion 40 and the clamping assembly 10 can be a hollow rectangular parallelepiped structure, or can be an "L" shape, a "Δ" shape, or other different shapes. Regardless of the shape of the combination of the two, the shape of the first clamping portion and the second clamping portion after being fixedly connected is a rectangular parallelepiped with a through hole in the middle, so as to ensure the clamping and fixing strength of the clamping assembly to the transducer assembly.

[0084] In some embodiments, a wire placement groove 50 is provided at one end of the first clamping portion 101 away from the second clamping portion 102 , and the wire placement groove 50 is used to accommodate a signal transmission line connected to the transducer assembly.

[0085] It can be understood that, through the design of the wire slot 50, the signal transmission line can pass through the wire slot 50, so as to facilitate the up and down movement of the signal line.

[0086] The embodiment of the present application also provides a solid physics simulation observation system.

[0087] Figure 3 FIG. 1 is a schematic diagram of a solid physics simulation observation system provided in an embodiment of the present application. Figure 3 As shown, the system may include a control device 1, at least two solid physics simulation observation devices 2 as described above, and at least two solid physics simulation observation devices 2 are fixedly connected to the control device 1;

[0088] The transducer component 20 in at least one of the at least two solid physics simulation observation devices 1 is an excitation transducer component, which is used to simulate the excitation of the seismic wave field;

[0089] The transducer component 20 in at least one of the at least two solid physics simulation observation devices 1 is an excitation transducer component, which is used to simulate the reception of seismic wave fields.

[0090] It can be understood that, in a specific application process, the solid physics simulation observation system needs to include at least two solid physics simulation observation devices 1 in the embodiment of the present application, which are used for signal excitation and reception respectively.

[0091] It can be understood that the control device 1 can be a positioning machine tool, and two gantry-type three-dimensional coordinate measuring machines can be selected to achieve high-precision three-dimensional spatial positioning of the transducer component 20. The three-dimensional spatial positioning error of the gantry-type three-dimensional coordinate measuring machine is less than 0.01 mm, and its measurement range is larger than the simulated working area range of the three-dimensional solid model, and the two gantry-type three-dimensional coordinate measuring machines can have the same three-dimensional spatial measurement range.

[0092] In some embodiments, the solid state physics simulation observation device 2 can be fixedly connected to the control device 1 through a fixed card slot of its device fixing part.

[0093] The description and functions of the above-mentioned equipment can be understood by referring to the contents of the solid physics simulation observation equipment section, which will not be repeated here.

[0094] The following is an introduction to the working principle of the solid physics simulation observation device in the embodiment of the present application by taking the control method of a single solid physics simulation observation device 1 and the control device being a gantry-type three-coordinate measuring machine as an example:

[0095] By controlling the positioning machine of the high-precision three-dimensional coordinate measuring machine to move vertically downward, when the transducer component probe comes into contact with the solid model, the clamping component compresses the spring, and the spring squeezes the transducer component to couple closely with the surface of the solid model, thereby realizing the solid surface elastic wave acquisition of the solid model. By controlling the movement of the three-dimensional coordinate positioning machine where the transducer component is located in three-dimensional space, the excitation / reception transducer component can be realized according to the designed observation system for acquisition. The nine-component simulation acquisition of the solid model elastic wave can be realized by replacing the longitudinal wave component, the shear wave SV component, and the shear wave SH component for excitation, and replacing the longitudinal wave component, the shear wave SV component, and the shear wave SH component for reception.

[0096] The solid physics simulation observation equipment and system for elastic wave nine-component seismic physics simulation acquisition provided in the embodiment of the present application can greatly improve the simulation acquisition capability of the solid model elastic wave nine-component signal. Specifically: through the split design between the clamping component and the transducer component, the solid surface acquisition of the conventional longitudinal and transverse wave ultrasonic transducer component can be realized through the simple assembly between the clamping component and the transducer component, and the transducer component can be installed and disassembled at any time, breaking through the limitation of professional customization of the transducer component of the traditional observation device; the lateral size of the designed clamping component can be controlled to within 18mm at the minimum, and more near-offset moment signals can be collected, which maximizes the acquisition of near-offset effective signals (1:10000 scale simulation, the minimum offset distance can be reduced to 200m); the bottom of the clamping component is designed with a special spring buckle (i.e., a wedge-shaped protrusion), which can effectively control the spring when it is stressed. The torsional movement can accurately control the simulated excitation and reception of the SV and SH components of the shear wave, truly realizing the accurate simulated acquisition of the nine-component signals of the elastic wave of the equipment; the clamping components can have the same size, and the upper part of the clamping components can be matched with the control equipment through a locking design, ensuring that the acquisition results of elastic waves of different components have good consistency, and the positioning error of the solid model collected by different components can be less than 0.1mm; the solid physics simulation observation equipment can be mounted on a new high-precision three-dimensional coordinate measuring machine, and the positioning error of the excitation / receiving transducer at any position in the three-dimensional space is less than 0.01mm, which is more than 5 times higher than the positioning accuracy of previous devices.

[0097] The solid physics simulation observation system and its working principle provided by the present application will be introduced in combination with specific embodiments.

[0098] It can be understood that in this embodiment, the transducer component is a shear wave probe or a longitudinal wave probe, and the bottom of the through hole composed of the first clamping part and the second clamping part of the clamping component has four wedge-shaped protrusions evenly distributed along the circumference of the through hole, which are used to fix the second end of the spring to the clamping component, and the through hole composed of the first clamping part and the second clamping part includes a first accommodating cavity and a second accommodating cavity, and the shear wave probe or the longitudinal wave probe can move vertically up and down in the second accommodating cavity; a fixed sleeve for fixing the first end of the spring is fixedly installed at the lower part of the shear wave probe or the longitudinal wave probe as the fixing part of the shear wave probe or the longitudinal wave probe, and a fixed sleeve for fixing the shear wave probe or the longitudinal wave probe is fixedly installed at the upper part of the shear wave probe or the longitudinal wave probe, and the control device can be a high-precision three-coordinate positioning machine tool, and the two solid physics simulation observation devices can be fixedly installed on the two high-precision three-coordinate positioning machine tools.

[0099] In this embodiment, two longitudinal wave probes with a diameter of 12 mm and a length of 50 mm are selected for the excitation and reception of longitudinal wave signals, and two shear wave probes with a diameter of 14 mm and a length of 50 mm are selected for the excitation and reception of shear wave SV component or shear wave SH component signals. Two clamping assemblies with an inner diameter of 12 mm are manufactured according to the size of the longitudinal wave probe, and two clamping assemblies with an inner diameter of 14 mm are manufactured according to the size of the shear wave probe. Springs of corresponding sizes are selected and loaded on the middle of the four longitudinal / shear wave probes, and fixed sleeves of corresponding sizes are selected and fixed on the upper and lower ends of the four longitudinal / shear wave probes. The four longitudinal / shear wave probes with springs installed are clamped and fixed using the processed clamping assemblies.

[0100] The clamped shear wave probe is rotated and fixed to the direction of the shear wave SV component through the four wedge-shaped protrusions at the bottom of the clamping assembly, which can simulate the excitation of the shear wave SV component signal; the clamped shear wave probe is rotated and fixed to the direction of the shear wave SH component through the four wedge-shaped protrusions at the bottom of the clamping assembly, which can simulate the reception of the shear wave SH component signal. The clamping assemblies with the shear wave probe installed are respectively loaded on the bottom of two high-precision three-coordinate positioning machine tools. The two high-precision three-coordinate positioning machine tools are respectively used to install and clamp the shear wave probe for signal excitation and the shear wave probe for signal reception. The following description is made by the excitation positioning machine tool and the receiving positioning machine tool to distinguish the high-precision three-coordinate positioning machine tools installed with different shear wave probes. The excitation positioning machine tool controls the three-dimensional position movement of the shear wave probe SV component, and the other receiving positioning machine tool controls the three-dimensional position movement of the shear wave probe SH component.

[0101] According to the solid physics simulation observation system, the plane position information of the shear wave excitation / receiving point on the solid model can be obtained. Combined with the top surface elevation of the solid model, the three-dimensional spatial coordinates of the high-precision positioning machine where the shear wave excitation / receiving probe is located can be calculated. The high-precision three-coordinate positioning machine is controlled to move the shear wave excitation / receiving probe to 5mm above the specified acquisition position of the solid model. The high-precision three-coordinate positioning machine where the shear wave excitation / receiving probe is located is controlled to move vertically downward by 5mm + the maximum deformation range of the spring. When the high-precision three-coordinate positioning machine drives the shear wave excitation / receiving probe to contact the surface of the solid model, the high-precision three-coordinate positioning machine continues to drive the clamping assembly to squeeze the spring to produce deformation, and the spring applies downward stress to the shear wave excitation / receiving probe. The shear wave excitation / receiving probe is squeezed by the spring and tightly coupled with the surface of the solid model through the solid coupling agent. When the high-precision three-coordinate positioning machine moves vertically downward, the shear wave excitation / receiving probe is controlled to collect signals on the surface of the solid model. At this time, an elastic wave component collection signal of the shear wave SV component excitation / shear wave SH component reception in the solid model can be obtained.

[0102] After the signal acquisition at one position is completed, the high-precision three-coordinate positioning machine where the excitation / receiving probe is located is controlled to move vertically upward by 5mm + the maximum deformation range of the spring, and the shear wave excitation / receiving probe is separated from the top surface of the solid model. According to the solid physics simulation observation system, the high-precision three-coordinate positioning machine is controlled to move the excitation / receiving probe to 5mm above the next solid model acquisition position, and the shear wave excitation / receiving probe is pressed down to the surface of the solid model to complete the solid surface signal acquisition at the next point of the solid model. Repeat the above acquisition process to complete the signal acquisition work at different positions of the solid model point by point. This simulation acquisition can obtain the simulation acquisition results of the single elastic wave component of the solid model shear wave SV excitation / shear wave SH reception.

[0103] According to the above acquisition scheme, by rotating the different polarization directions of the shear wave excitation / receiving probe, repeating the object model acquisition work under the specified solid physical simulation observation system, four elastic wave component acquisition signals of the solid model, namely, shear wave SV component excitation / shear wave SV component reception, shear wave SV component excitation / shear wave SH component reception, shear wave SH component excitation / shear wave SH component reception, and shear wave SH component excitation / shear wave SV component reception, can be obtained respectively. By replacing the longitudinal wave probes at the excitation and receiving ends respectively, repeating the solid model acquisition work under the specified solid physical simulation observation system, five elastic wave component acquisition signals of the solid model, namely, shear wave SV component excitation / longitudinal wave reception, shear wave SH component excitation / longitudinal wave reception, longitudinal wave excitation / shear wave SV component reception, longitudinal wave excitation / longitudinal wave reception, and longitudinal wave excitation / shear wave SH component reception, can be obtained respectively. Repeating the above-mentioned excitation and reception acquisition experiments of nine different components, the elastic wave nine-component seismic physics simulation experiment results of the specified solid model can be obtained.

[0104] The solid physics simulation observation system provided in this embodiment can have the following positive effects: through the split design between the clamping component and the longitudinal and transverse wave probes, the designed special clamping component can realize the solid surface acquisition of conventional longitudinal and transverse wave ultrasonic transducers through simple assembly between the longitudinal and transverse wave probes, and the ultrasonic transducer can be installed and disassembled at any time, breaking through the limitation of professional customization of ultrasonic transducers; the design of the hollow rectangular clamping component greatly reduces the lateral size of the clamping component while ensuring the structural strength of the clamping component, and the minimum lateral size can be controlled to within 18mm, thereby maximizing the acquisition of effective signals at close offset distances. For example, in the case of 1:10000 scale simulation, the minimum offset distance can be reduced to 200m; through the design of the four wedge-shaped protrusions at the bottom of the clamping component as spring buckles, It can effectively control the torsional movement of the spring when it is stressed, and can accurately control the simulated excitation and reception of the SV component and SH component of the shear wave, truly realizing the accurate simulated acquisition of the nine-component signal of the elastic wave of the system; through the clamping components of uniform size, the top of the clamping components is designed with a lock (i.e., the lock-type fixed connection between the fixed card slot of the fixed part of the equipment and the control device) to achieve matching installation with the positioning machine tool, ensuring good consistency in the acquisition results of elastic waves of different components, and the positioning error of the solid model collected by different components is less than 0.1mm; by loading the solid physics simulation observation equipment on a high-precision three-coordinate positioning machine tool, the positioning error of the longitudinal and shear wave probes at any position in the three-dimensional space can be less than 0.01mm, which can improve the three-dimensional spatial positioning accuracy of the solid model elastic wave acquisition by more than 5 times compared with the past.
