Description

[0002] Seismic physical simulation experiments are used to simulate the propagation law of real field seismic wave field. With the development of actual field seismic exploration from P-wave exploration to P-S wave joint exploration, seismic physical simulation experiments need to be able to realize the real simulation of the propagation law of various complex wave fields such as P wave, S wave and converted wave. At present, a kind of direct hard contact type simulation acquisition on the surface of a solid model is used to realize the simulation of the propagation law of field seismic wave field.

[0003] The existing physical model solid surface acquisition technology realizes the solid surface acquisition of the physical model through a special solid model acquisition device and a solid acquisition transducer (ultrasonic transducer) matched with the device. However, the solid model acquisition device has the following problems: 1. The ultrasonic transducer core and the shell are customized professionally, and the universality is poor, and the manufacturing cost and maintenance cost of the whole device are high; 2. The integrated design of the force device and the ultrasonic transducer makes the horizontal size of the device large, the minimum offset distance of the simulation acquisition is large, which leads to the lack of near offset reflection information in the simulation experiment result, for example, for a solid model acquisition device with an ultrasonic transducer diameter of 10mm and a device horizontal size of more than 30mm, the minimum center distance of the excitation and reception points is more than 35mm, and when 1:10000 scale seismic physical simulation is carried out, 0-350m offset reflection information will be lost; 3.

BRIEF DESCRIPTION OF DRAWINGS

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings needed to be used in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments described in the present application, and those skilled in the art can also obtain other drawings according to these drawings without creative labor.

[0028] Figure 1 Fig. 1 shows a schematic diagram of the clamping assembly provided in the embodiments of the present application;

[0029] Figure 2 Fig. 2 shows a schematic diagram of the solid physical simulation observation device provided in the embodiments of the present application;

[0031] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0032] As mentioned earlier, existing physical model solid surface acquisition technology uses a dedicated solid model acquisition device. This device integrates the transducer and force application mechanism. To improve stability, the transducer has a cylindrical structure, with the probe positioned below it. During seismic wave field acquisition, the transducer moves downwards under the force application mechanism, bringing the probe into contact with the solid surface of the seismic wave field to be acquired. This device has the following problems: 1. The ultrasonic transducer core and shell are custom-made, resulting in poor versatility and high manufacturing and maintenance costs for the entire device; 2. The integrated design of the force application mechanism and ultrasonic transducer leads to a large lateral dimension and a large minimum longitudinal offset distance in the simulation, resulting in a lack of near-offset reflection information in the simulation results; 3. During the probe's raising and lowering process, the spring compresses the ultrasonic transducer, causing rotational movement, making it difficult to accurately control the polarization direction of the shear wave acquisition.

[0033] To address the aforementioned issues, this application provides a solid-state physics simulation observation device. This device employs a detachable clamping assembly to fix the transducer component, enabling combinations of different transducer component models with the clamping assembly, thus enhancing the device's versatility. By fixing the first end of the spring to the fixing part of the transducer component and the second end of the spring to the clamping assembly, the change in the polarization direction of the transducer component caused by the torsional motion of the transducer component when the spring is compressed can be avoided, achieving more accurate and reliable acquisition of the seismic wave field. Furthermore, the clamping part of the transducer component (i.e., the first and second clamping parts after fixed connection) adopts a cuboid structure. The direction of the longer side of the cuboid closest to the spring is used as the force direction of the clamping component, and the direction of the shorter side of the cuboid closest to the spring is used as the elastic wave propagation direction. This reduces the device's lateral dimensions, allowing for the acquisition of more near-offset moment signals and improving the acquisition of effective near-offset moment signals.

[0034] The solid-state physics simulation and observation device in the embodiments of this application will now be described in conjunction with the accompanying drawings.

[0035] Figure 1 The diagram shown is a schematic of a clamping assembly provided in an embodiment of this application. Figure 1 In the diagram, 'a' and 'b' represent schematic diagrams of the clamping components from different perspectives.

[0036] Figure 2 The image shown is a schematic diagram of a solid-state physics simulation and observation device provided in an embodiment of this application.

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

[0038] The clamping assembly 10 comprises a first clamping part 101 and a second clamping part 102, the first clamping part 101 comprises a first groove 1011, and the second clamping part 102 comprises a second groove 1021, when the first clamping part 101 is fixedly connected with the second clamping part 102, the first groove 1011 and the second groove 1021 combine into a through hole 103.

[0039] The transducing assembly 20 is provided with a fixed part at one end, a spring 30 is installed in the middle of the transducing assembly 20, and the fixed part (for example Figure 2 the fixed sleeve 201 in the fixed sleeve 201) is used to fix the first end of the spring 30 close to the fixed part.

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

[0041] The end of the transducing assembly 20 away from the fixed part passes through the through hole 103 formed by the fixed connection of the first clamping part 101 and the second clamping part 102, the second end of the spring 30 close to the second end of the clamping assembly 20 is fixed to the clamping assembly 10, the clamping assembly 10 moves vertically downward along the direction of the through hole 103, compresses the spring 30, and realizes the collection of elastic waves on the solid surface.

[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 transducing assembly 20 can be realized, that is, by fixedly connecting the first clamping part 101 and the second clamping part 102, the transducing 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 transducing assembly 20 can be removed from the clamping assembly 10, at this time, other models of transducing assemblies can be 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 realize the replacement of the transducing 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 different models of transducing assemblies can be realized, so that the solid physical simulation observation equipment in the present application has stronger universality.

[0043] It can be understood that the second end of the spring 30 can be fixed to the surface of the end of the clamping assembly 10 close to the spring, for example Figure 1The bottom surface of the clamping assembly 10 is fixed to the peripheral part of the through hole of the clamping assembly bottom surface, and the clamping assembly 10 can be controlled to move vertically downward, so that the transducer assembly 20 contacts the surface of the solid model, and 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 under stress, and when the spring 30 is compressed under stress, the torsional motion of the spring can be avoided due to the fixing of the spring to the transducer assembly and the clamping assembly respectively.

[0044] It can be understood that by fixing the two ends of the spring 30 through the fixing part of the transducer assembly 20 and the clamping assembly 10 respectively, the torsional motion of the spring 30 under stress can be effectively controlled, and the change of the polarization direction of the transducer assembly when the spring 30 is in torsional motion can be avoided, so that the simulation excitation and reception of the solid physical simulation observation equipment to the transverse wave component in the seismic wave field, including the transverse wave SV component (vertical polarization transverse wave, Vertical Shear wave) and the transverse wave SH component (horizontal polarization transverse wave, Horizontal Shear wave) can be accurately controlled, and the accuracy and reliability of the elastic wave component collection can be ensured. The transverse wave SV component can be understood as the component of the transverse wave in the vertical polarization direction, and the transverse wave SH component can be understood as the component of the transverse wave in the horizontal polarization direction.

[0045] It can be understood that the first groove 1011 of the first clamping part 101 and the second groove 1021 of the second clamping part 102 can form a through hole 103 when the first clamping part 101 and the second clamping part 102 are fixedly connected, and the through hole 103 can be used to accommodate the transducer assembly 20, and the through hole 103 is used to accommodate the end of the transducer assembly 20 away from the fixing part.

[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 equipment for controlling the vertical motion of the clamping assembly 10 and the transducer assembly and compressing the spring can be connected as an organic whole, so as to realize the excitation and collection of the elastic wave of the solid model surface simulation seismic wave field.

[0047] In some embodiments, the through hole 103 can be cylindrical, and the cylindrical through hole has the same diameter along the through hole direction. In other embodiments, the through hole can be multi-segment cylindrical, and the diameter of each segment of the cylindrical through hole can 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 assembly 20, and further the shape of the first groove 1011 and the second groove 1021 can match the outer contour of the transducer assembly 20. For example, when the outer contour of the transducer assembly 20 is cylindrical, the through hole 103 matches the shape of the transducer assembly 20, which is cylindrical, and the first groove 1011 and the second groove 1021 can be semicircular arc grooves with the same size and shape; when the outer contour of the transducer assembly 20 is a multi-segment cylindrical shape with different diameters, the through hole 103 can be a multi-segment cylindrical shape that can meet the back-and-forth movement of the transducer assembly in the through hole, and further the shape of the first groove 1011 and the second groove 1021 can be a multi-segment semicircular arc groove with the same size and different diameters.

[0049] In some embodiments, the spring 30 can be a general steel spring, the inner diameter of the spring 30 can match the diameter of the transducer assembly 20, and the length of the spring 30 and the wire diameter of the spring 30 can be determined according to the main body size of the transducer assembly 20, the stress coupling effect of the solid physical simulation observation equipment on the solid model, the spring stress size and other factors. It can be understood that when the solid physical simulation observation equipment collects signals from the solid model, the signal collection quality is positively correlated with the coupling pressure of the transducer assembly 20 loaded on the surface of the solid model, and when the coupling pressure is greater than a certain value, the signal collection quality of the surface of the solid model is basically stable. Therefore, the maximum deformation stress of the spring 30 can be greater than the optimal coupling stress of the transducer assembly 20 pressing the surface of the solid model, so as to ensure the basic stability of the signal collection quality.

[0050] In some embodiments, the first clamping part 101 and the second clamping part 102 can be provided with position-matched screw holes, and the first clamping part 101 and the second clamping part 102 can be fixedly connected by screws to splice into a complete structure to clamp transducer assemblies of different models.

[0051] In some embodiments, the end of the first clamping part 101 and the second clamping part 102 connected and attached can include a mortise and tenon structure, which can fixedly connect the first clamping part 101 and the second clamping part 102 to splice into a complete structure to clamp transducer assemblies of different models.

[0052] In some embodiments, the first clamping part 101 and the second clamping part 102 are provided with at least three protruding points 104 near the end close to the spring 30 along the periphery of the through hole 103, 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 the 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 part 101 and the second clamping part 102 are fixedly connected, and the first end of the spring 30 is fixed by the fixing part of the transducer assembly 20, so as to realize the fixation of the spring 30, avoid the torsional motion of the spring 30 when it is stressed, and further affect the polarization direction of the transducer assembly 20. The at least three protruding points 104 can be uniformly distributed or non-uniformly distributed around the through hole 103. The fixation of the spring 30 can be realized by the at least three protruding points 104. The number and position of the protruding points can be adjusted based on requirements or actual application scenarios, for example, three protruding points can be arranged at equal intervals, four protruding points can be arranged at equal intervals, and the like.

[0054] In some embodiments, four wedge-shaped protruding points 104 are arranged at equal intervals around the through hole 103 near one end of the spring, and the four wedge-shaped protruding points are used to fix the second end of the spring close to the second end of the clamping assembly.

[0055] It can be understood that the wedge-shaped protruding points can be used to realize the fixation of the second end of the spring 30. The four wedge-shaped protruding points arranged at equal intervals have an angle interval of 90 degrees between each other. When the transducer assembly 20 is solidly collected and the compression spring 30 is stressed, the top (i.e., the second end) of the spring 30 is fixed by the protruding points, which suppresses the lateral torsional motion of the stressed spring 30, and ensures that the polarization direction of the transducer assembly 20 does not change. In addition, based on the four wedge-shaped protruding points arranged at equal intervals, the polarization direction of the transducer assembly 20 can be rotated by 90 degrees by rotating the spring 30 to match the wedge-shaped protruding points, which can accurately control the excitation and reception of the two mutually perpendicular polarization directions of the transducer assembly 20.

[0056] It can be understood that the four wedge-shaped protruding points arranged at equal intervals and having an angle interval of 90 degrees between each other can realize accurate control of the polarization direction of the transducer assembly, and further realize solid model elastic wave nine-component simulation collection by replacing the excitation of the corresponding transverse wave SV component, transverse wave SH component and longitudinal wave component, and simultaneously replacing the reception of the corresponding transverse wave SV component, transverse wave SH component and longitudinal wave component. The elastic wave nine components can include: transverse wave SV component excitation / transverse wave SV component reception, transverse wave SV component excitation / transverse wave SH component reception, transverse wave SV component excitation / longitudinal wave reception, transverse wave SH component excitation / transverse wave SH component reception, transverse wave SH component excitation / transverse wave SV component reception, transverse wave SH component excitation / longitudinal wave reception, longitudinal wave excitation / longitudinal wave reception, longitudinal wave excitation / transverse wave SV component reception, and longitudinal wave excitation / transverse wave SH component reception.

[0057] In some embodiments, the through hole includes a first accommodating cavity 1031 and a second accommodating cavity 1032, 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 length 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 assembly 20, etc., and the diameter of the first accommodating cavity 1031 and the second accommodating cavity 1032 can be determined based on the diameter of the transducer assembly 20.

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

[0060] In some embodiments, the end of the transducer assembly 20 away from the fixed part can include a larger-diameter cylindrical segment, which can be formed by a fixed sleeve or integrated with the main body part of the transducer assembly, and then the diameter of the first accommodating cavity 1031 can match the diameter of the main body part of the transducer assembly 20, that is, the part between the cylindrical segment and the protruding part, to achieve the fixation of the transducer assembly, control the vertical downward movement distance of the transducer assembly 20, and avoid the transducer assembly 20 from being separated from below the clamping assembly 10, affecting the excitation and reception of signals; the diameter of the second accommodating cavity 1032 can match the diameter of the cylindrical segment to realize the back-and-forth movement of the cylindrical segment part in the through hole.

[0061] In some embodiments, when the spring is not deformed under force, the distance between the cylindrical segment 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, but when the distance between the cylindrical segment and the spring is greater than the length of the first accommodating cavity 1031, it needs to satisfy that the distance between the end surface of the cylindrical segment 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 stressed, the transducer assembly 20 and the clamping assembly 10 will move relatively, at this time the spring is compressed under stress, and when the spring 30 is deformed to the maximum elastic deformation, at least part of the cylindrical segment needs to be still located in the through hole, so as to avoid the transducer assembly 20 from moving horizontally in the through hole 103 due to the cylindrical segment being separated from the through hole 103, so that the polarization direction of the transducer assembly 20 changes, affecting the accurate simulation and acquisition of the elastic wave of the simulated seismic wave field.

[0062] In some embodiments, the transducer assembly 20 can be a general-purpose transducer with a cylindrical structure. The length of the cylinder of the transducer assembly 20 can be greater than 50 mm, and the diameter of the main body of the cylinder can be no greater than 14 mm. The general-purpose transducer type can include: a "|"-shaped transducer with the same diameter at both the top and bottom of the cylinder; a "T"-shaped transducer with a larger diameter at the top and a smaller diameter at the bottom (the lower part of the transducer assembly is its main body); and a "⊥"-shaped transducer with a smaller diameter at the top and a larger diameter at the bottom (the upper part of the transducer assembly is its main body).

[0063] In some embodiments, when the transducer is a "|" type transducer or a "T" type transducer, the fixing part of the transducer 20 can be a fixing sleeve for fixing the first end of the spring 30.

[0064] It is understood that the fixing part can be integrally formed with the transducer assembly, or it can be formed by other cylindrical structures, as long as it can effectively fix the first end of the spring 30. This application does not limit this.

[0065] In some embodiments, the fixing portion of the transducer assembly 20 is an annular protrusion, and a fixing sleeve (e.g., a fixing sleeve) is fixedly installed at the end of the transducer assembly 20 away from the fixing portion. Figure 2 The fixed sleeve 202 in the first receiving cavity 1031 has an outer diameter that matches the diameter of the second receiving cavity 1031, and the outer diameter of the end of the transducer 20 away from the fixed part matches the diameter of the first receiving cavity 1031. It can be understood that the fixed part and the transducer 20 are integrally formed. In other embodiments, the fixed part can also be a cylindrical segment, that is, the transducer 20 is a "⊥" shaped transducer, and this application does not limit this.

[0066] 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 receiving cavity 1031, and 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 receiving cavity 1032.

[0067] It is understandable 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 receiving cavity 1032. This can prevent the transducer component 20 from moving laterally in the through hole 103 due to the fixed sleeve disengaging from the through hole 103, which would cause a change in the polarization direction of the transducer component 20 and affect the accurate simulation and acquisition of elastic waves in the simulated seismic wave field.

[0068] It can be understood that the spring 30 can be mounted in the middle of the transducing assembly 20, a fixed sleeve can be added to the upper part of the transducing assembly 20, the distance between the fixed sleeve and the fixed part can be greater than or equal to the sum of the length 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 cannot be twisted due to compression under force; and the vertical downward movement distance of the transducing assembly 20 is controlled, so as to avoid the transducing assembly 20 from being separated from the clamping assembly 10, affecting the excitation and reception of the signal; in addition, at least part of the fixed sleeve can still be located in the second accommodating cavity 1032 when the spring 30 produces the maximum elastic deformation, so as to avoid the transducing assembly 20 from moving laterally in the through hole 103 due to the fixed sleeve being separated from the second accommodating cavity 1032, so that the polarization direction of the transducing assembly 20 changes, affecting the accurate simulation and acquisition of the elastic wave of the simulated seismic wave field.

[0069] In some embodiments, the transducing assembly 20 includes a first transducing part and a second transducing part, the fixed part of the transducing assembly is a fixed sleeve (for example, the fixed sleeve 201 in Figure 2 The outer diameter of the second transducing part matches the diameter of the second accommodating cavity 1032, and the outer diameter of the first transducing part of the transducing assembly 20 matches the diameter of the first accommodating cavity 1031. It can be understood that the first transducing part and the second transducing part are integrally formed, for example, the transducing assembly can be a “T” type transducer, the first transducing part can be the main body part with a smaller diameter of the “T” type transducer, and the second transducing part can be the upper part with a larger diameter of the “T” type transducer. The distance between the fixed sleeve and the second transducing part is greater than or equal to the sum of the length of the spring 30 and the first accommodating cavity 1031, and at least part of the second transducing part is located in the second accommodating cavity 1032 when the spring 30 produces the maximum elastic deformation.

[0070] In some embodiments, the fixed part of the transducing assembly 20 is a first fixed sleeve (for example, the fixed sleeve 201 in Figure 2 The transducing assembly is fixedly installed with a second fixed sleeve (for example, the fixed sleeve 202 in 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 transducing assembly between the first fixed sleeve and the second fixed sleeve matches the diameter of the first accommodating cavity. It can be understood that the transducing assembly is a “│” type transducer with consistent diameters in the upper and lower parts, the spring 30 can be mounted in the middle of the transducer, and the fixed sleeve can be fixedly installed in the upper and lower parts of the transducer (for example, the fixed sleeves 201 and 202 in Figure 2The first fixed sleeve and the second fixed sleeve are respectively used for fixing the spring and the transducer.

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

[0072] It can be understood that the fixed sleeve fixedly installed on the first transducing part in the "T"-shaped transducer and the first fixed sleeve fixedly installed on the lower part in the "│"-shaped transducer can correspond to the fixed part of the annular protrusion in the foregoing embodiment, the second transducing part in the "T"-shaped transducer and the second fixed sleeve fixedly installed on the upper part in the "│"-shaped transducer can correspond to the fixed sleeve installed on the end of the transducing assembly away from the fixed part in the foregoing embodiment, the spring 30 can be installed on the middle part of the transducing assembly 20, the upper and lower fixed parts (for example, the annular protrusion or the fixed sleeve) can be respectively arranged on the upper and lower parts of the transducing assembly 20, the distance between the upper and lower fixed parts can be greater than or equal to the sum of the length of the spring 30 and the first accommodating cavity 1031, and the upper fixed part can still be located in the second accommodating cavity 1032 when the spring produces the maximum elastic deformation, so that the spring 30 can be fixed between the lower fixed part and the clamping assembly and cannot produce the torsional motion due to the compression under force; and the motion distance of the transducing assembly 20 in the vertical downward direction is controlled, so as to avoid the transducing assembly 20 from being separated from the clamping assembly 10 and affecting the excitation and reception of the signal; in addition, at least part of the upper fixed part can still be located in the second accommodating cavity 1032 when the spring 30 produces the maximum elastic deformation, so as to avoid the transducing assembly 20 from producing the lateral motion in the through hole 103 due to the separation of the upper fixed part from the second accommodating cavity 1032, so that the change of the polarization direction of the transducing assembly 20 affects the accurate simulation and acquisition of the elastic wave of the simulated seismic wave field. The form of the fixed part in the embodiment of the application, for example, the integral molding or the fixed connection with other parts, is not limited, and other parts that can fix the spring and the transducing assembly are within the protection scope of the application.

[0073] It can be understood that the transducer assembly (for example, longitudinal and transverse wave excitation / receiving transducer) can be installed at the middle body position of the spring 30 through its own structure and fixing components, the transducer assembly 20 is loaded in the through hole 103 of the clamping assembly 10, and the transducer assembly 20 and the clamping assembly 10 are installed as a whole through the two detachable structures (that is, the first clamping part 101 and the second clamping part 102) of the clamping assembly 10, wherein the lower part of the spring 30 (that is, the first end of the spring 30) is connected with the lower part fixing component of the transducer assembly 20, the upper part of the spring 30 (that is, the second end of the spring 30) is fixed by the protruding point of the clamping loading bottom of the transducer assembly 20, when the upper part of the spring is fixed, the polarization direction of the transducer assembly transverse wave probe is adjusted to SV / SH direction, then the lower part of the spring is fixed with the lower part fixing component of the transducer assembly to form a whole, and through the mutual position relationship between the spring and the protruding point, the horizontal polarization direction of the transverse wave transducer assembly can be changed by 90 degrees each time.

[0074] In some embodiments, the fixing sleeve installed on the transducer assembly, for example, the fixing sleeve installed on the upper part and / or the lower part of the transducer assembly, can be a circular tube type structure, the length of which can be controlled within 5-10 mm, the inner diameter of which matches the main body size of the transducer assembly, and the outer diameter of which can be 2-3 mm larger than the main body diameter of the transducer assembly. The fixing sleeve can be tightly attached to the surface of the transducer assembly by means of bonding, threading or screwing, etc., to realize the fixed connection with the transducer assembly.

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

[0076] It can be understood that the device fixing part 40 is used to fix the clamping assembly 10 clamping the transducer assembly 20 to a control device, the fixing clamping groove 401 of the device fixing part 40 can match the component form of the control device used to fix the device fixing part 40, so as to ensure that the device clamping assembly 10 can be loaded at the same position of the control device each time; the fixing clamping groove 401 can be installed on the control device by means of a lock buckle.

[0077] In some embodiments, the control device can be a positioning machine tool, and two gantry type three-coordinate measuring machines can be selected to realize high-precision positioning of the transducer assembly 20 in three-dimensional space, the three-dimensional space positioning error of the gantry type three-coordinate measuring machine is less than 0.01 mm, the measurement range of the gantry type three-coordinate measuring machine is greater than the simulation work area range of the three-dimensional solid model, and the two gantry type three-coordinate measuring machines can have the same three-dimensional space measurement range.

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

[0079] In some embodiments, the first clamping part and the second clamping part are fixedly connected to form a cuboid, a direction in which a longer side of a side of the cuboid close to the spring is located is taken as a force direction of the clamping assembly, and a direction in which a shorter side of the side of the cuboid close to the spring is located is taken as an elastic wave propagation direction.

[0080] In some embodiments, the device fixing part 40 and the clamping assembly 10 can be an integrally formed structure, and can be a hollow cuboid. The clamping assembly 10 is located at a lower part of the hollow cuboid, as shown in FIG. 1. 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 an upper part of the cuboid and can protrude from the upper part of the cuboid, so as to be fixedly connected to the gantry three-coordinate measuring machine.

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

[0082] It can be understood that the hollow cuboid design of the combination of the device fixing part 40 and the clamping assembly 10 can greatly reduce the transverse size of the clamping assembly while ensuring the structural strength of the clamping assembly.

[0083] In some embodiments, the combination of the device fixing part 40 and the clamping assembly 10 can be in the form of a hollow cuboid structure, an "L" shape, a "Δ" shape, or the like. Regardless of the shape of the combination, the shape of the first clamping part and the second clamping part after being fixedly connected is a cuboid with a through hole in the middle, so as to ensure the clamping and fixing strength of the clamping assembly on the transducer assembly.

[0084] In some embodiments, the first clamping part 101 is provided with a wire slot 50 at one end away from the second clamping part 102, and the wire slot 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, and the up and down movement of the signal line is facilitated.

[0086] The application also provides a solid physical simulation observation system.

[0087] Figure 3 A schematic diagram of a solid physical simulation observation system provided by an embodiment of the application is shown. As Figure 3 As shown, the system can include a control device 1 and at least two solid physical simulation observation devices 2 described above, and the at least two solid physical simulation observation devices 2 are fixedly connected to the control device 1.

[0088] The transducer assembly 20 in at least one of the at least two solid physical simulation observation devices 1 is an excitation transducer assembly for simulating the excitation of a seismic wave field.

[0089] The transducer assembly 20 in at least one of the at least two solid physical simulation observation devices 1 is an excitation transducer assembly for simulating the excitation of a seismic wave field.

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

[0091] It can be understood that the control device 1 can be a positioning machine tool, and two gantry three-coordinate measuring machines can be selected to realize high-precision positioning of the transducing component 20 in three-dimensional space. The positioning error of the gantry three-coordinate measuring machine in three-dimensional space is less than 0.01 mm, the measurement range of the gantry three-coordinate measuring machine is greater than the simulation work area range of the three-dimensional solid model, and the two gantry three-coordinate measuring machines can have the same three-dimensional space measurement range.

[0092] In some embodiments, the solid physical simulation observation device 2 can be fixedly connected to the control device 1 through the fixing clamping groove of the device fixing portion of the solid physical simulation observation device 2.

[0093] The description and functions of the above devices can be understood by referring to the content of the solid physical simulation observation device part, and will not be repeated here.

[0094] The following describes the working principle of the solid physical simulation observation device in the embodiments of the present application by taking the control method of a single solid physical simulation observation device 1 and taking the control device as a gantry three-coordinate measuring machine as an example:

[0095] When the transducing component probe starts to contact the solid model, the clamping component compresses the spring, and the spring extrudes the transducing component and the surface of the solid model to be tightly coupled, so as to realize the elastic wave collection of the solid surface of the solid model. By controlling the movement of the three-coordinate positioning machine tool in which the transducing component is located in three-dimensional space, the transducing component can be collected according to the designed observation system. By replacing the longitudinal wave component, the transverse wave SV component, and the transverse wave SH component for excitation and replacing the longitudinal wave component, the transverse wave SV component, and the transverse wave SH component for receiving, respectively, the nine-component simulation collection of the elastic wave of the solid model can be realized.

[0096] The solid physical simulation observation device and system for elastic wave nine-component seismic physical simulation acquisition provided in the embodiments of the present application can greatly improve the simulation acquisition capability of the elastic wave nine-component signals of the solid model. Specifically, through the split design between the clamping assembly and the transducing assembly, the solid surface acquisition of the conventional longitudinal and transverse wave ultrasonic transducing assembly can be realized through the simple assembly between the clamping assembly and the transducing assembly. The transducing assembly can be installed and detached at any time, thereby breaking through the limitation of the professional customization of the transducing assembly of the traditional observation device. The transverse dimension of the clamping assembly can be controlled to be within 18 mm at the minimum, more near offset distance signals can be acquired, and the acquisition of the effective signals of the near offset distance is improved as much as possible (1:10000 scale simulation, the minimum offset distance can be reduced to 200 m). The bottom of the clamping assembly is designed with a special spring buckle (i.e. wedge-shaped protruding point), the torsional movement of the spring under stress can be effectively controlled, the simulation excitation and reception of the transverse wave SV and SH components can be accurately controlled, and the accurate simulation acquisition of the elastic wave nine-component signals of the device is truly realized. The clamping assemblies can have the same size, the upper part of the clamping assembly can be matched and installed with the control device through the lock buckle type design, the consistency of the acquisition results of different component elastic waves is ensured, and the positioning error of the solid model acquired by different components can be less than 0.1 mm. The solid physical simulation observation device can be mounted on a new type of high-precision three-coordinate measuring machine, the positioning error of the excitation / reception transducer at any position in the three-dimensional space is less than 0.01 mm, and the positioning accuracy is improved by more than 5 times compared with the previous device.

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

[0098] It can be understood that in the present embodiment, the transducing assembly is a transverse wave probe or a longitudinal wave probe, the bottom of the through hole composed of the first clamping part and the second clamping part of the clamping assembly is distributed with four wedge-shaped protruding points at equal intervals along the periphery of the through hole, for fixing the second end of the spring to the clamping assembly, 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 transverse wave probe or the longitudinal wave probe can move vertically up and down in the second accommodating cavity. The lower part of the transverse wave probe or the longitudinal wave probe is fixedly installed with a fixed sleeve for fixing the first end of the spring as a fixed part of the transverse wave probe or the longitudinal wave probe, and the upper part of the transverse wave probe or the longitudinal wave probe is fixedly installed with a fixed sleeve for fixing the transverse wave probe or the longitudinal wave probe. The control device can be a high-precision three-coordinate positioning machine tool, and the two solid physical 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 longitudinal wave signal excitation and reception, respectively, and two transverse wave probes with a diameter of 14 mm and a length of 50 mm are selected for transverse wave SV component or transverse wave SH component signal excitation and reception, respectively. Two clamping assemblies with an inner diameter of 12 mm are processed according to the size of the longitudinal wave probes, and two clamping assemblies with an inner diameter of 14 mm are processed according to the size of the transverse wave probes. Corresponding size springs are selected and loaded in the middle of the four longitudinal / transverse wave probes, and corresponding size fixing sleeves are selected and fixed at the upper and lower ends of the four longitudinal / transverse wave probes. The four longitudinal / transverse wave probes with springs installed are clamped and fixed by using the processed clamping assemblies.

[0100] The clamped transverse wave probe is rotated and fixed to the transverse wave SV component direction through the four wedge-shaped protrusion points at the bottom of the clamping assembly, which can simulate the excitation of the transverse wave SV component signal; the clamped transverse wave probe is rotated and fixed to the transverse wave SH component direction through the four wedge-shaped protrusion points at the bottom of the clamping assembly, which can simulate the reception of the transverse wave SH component signal. The clamping assemblies with the transverse wave probes installed are loaded at the bottom of two high-precision three-coordinate positioning machines. The two high-precision three-coordinate positioning machines are used to install the clamped transverse wave probes for signal excitation and signal reception, respectively. In the following, the excitation positioning machine and the reception positioning machine are described to distinguish the high-precision three-coordinate positioning machines for installing different transverse wave probes. The excitation positioning machine controls the three-dimensional position movement of the transverse wave probe SV component, and the other reception positioning machine controls the three-dimensional position movement of the transverse wave probe SH component.

[0101] According to the solid physical simulation observation system, the planar position information of the transverse wave excitation / reception point in the solid model can be obtained, and combined with the elevation of the top surface of the solid model, the three-dimensional spatial coordinates of the high-precision positioning machine where the transverse wave excitation / reception probe is located can be calculated. The high-precision three-coordinate positioning machine is controlled to move the transverse wave excitation / reception probe to a position 5 mm above the specified collection position of the solid model. The high-precision three-coordinate positioning machine where the transverse wave excitation / reception probe is located is controlled to move vertically downward by 5 mm + the maximum deformation range of the spring. When the high-precision three-coordinate positioning machine drives the transverse wave excitation / reception probe to contact the surface of the solid model, the high-precision three-coordinate positioning machine continues to drive the clamping assembly to compress and deform the spring. The spring exerts a downward stress on the transverse wave excitation / reception probe, and the transverse wave excitation / reception probe is tightly coupled with the surface of the solid model through the solid coupling agent under the extrusion of the spring. When the vertical downward movement of the high-precision three-coordinate positioning machine ends, the transverse wave excitation / reception probe is controlled to perform a signal collection on the surface of the solid model, and at this time, an elastic wave component collection signal of the transverse wave SV component excitation / transverse wave SH component reception in the solid model can be obtained.

[0102] When the signal collection at a position is finished, the high-precision three-coordinate positioning machine bed where the excitation / receiving probe is located is controlled to move vertically upward by 5 mm + the maximum deformation range of the spring, the transverse wave excitation / receiving probe is separated from the top surface of the solid model, the high-precision three-coordinate positioning machine bed is controlled to move the excitation / receiving probe to 5 mm above the next solid model collection position according to the solid physical simulation observation system, the transverse wave excitation / receiving probe is pressed to the surface of the solid model, and the signal collection of the solid surface at the next point of the solid model is completed. The above collection process is repeated to complete the signal collection at different positions of the solid model point by point. This simulation collection can obtain the simulation collection results of the single elastic wave component of the solid model transverse wave SV excitation / transverse wave SH reception.

[0103] According to the above collection scheme, the object model collection work under the specified solid physical simulation observation system is repeated by rotating the transverse wave excitation / receiving probe in different polarization directions, and four elastic wave component collection signals of the solid model, i.e., transverse wave SV component excitation / transverse wave SV component reception, transverse wave SV component excitation / transverse wave SH component reception, transverse wave SH component excitation / transverse wave SH component reception, and transverse wave SH component excitation / transverse wave SV component reception, can be obtained respectively. By replacing the longitudinal wave probe at the excitation and reception ends respectively, the solid model collection work under the specified solid physical simulation observation system is repeated, and five elastic wave component collection signals of the solid model, i.e., transverse wave SV component excitation / longitudinal wave reception, transverse wave SH component excitation / longitudinal wave reception, longitudinal wave excitation / transverse wave SV component reception, longitudinal wave excitation / longitudinal wave reception, and longitudinal wave excitation / transverse wave SH component reception, can be obtained respectively. The excitation and reception collection experiments of the above nine different components are repeated, and the elastic wave nine-component seismic physical simulation experiment results of the specified solid model can be obtained.

[0104] The solid physical simulation observation system provided by the embodiment can have the following positive effects: through the split design between the clamping assembly and the longitudinal and transverse wave probe, the special clamping assembly is designed to realize the solid surface collection of the conventional longitudinal and transverse wave ultrasonic transducer through simple assembly between the longitudinal and transverse wave probe, the ultrasonic transducer can be installed and disassembled at any time, and the limitation of professional customization of the ultrasonic transducer is broken through; through the design of the hollow cuboid clamping assembly, the transverse size of the clamping assembly is greatly reduced while the structural strength of the clamping assembly is ensured, the transverse size can be controlled to be less than 18 mm, the collection of near offset effective signals is improved as much as possible, for example, in 1:10000 scale simulation, the minimum offset distance can be reduced to 200 m; through the design of the four wedge-shaped protrusions at the bottom of the clamping assembly as spring buckles, the torsional movement of the spring under stress can be effectively controlled, the simulation excitation and reception of the transverse wave SV component and SH component can be accurately controlled, and the accurate simulation and collection of the nine-component elastic wave signals of the system are truly realized; through the clamping assembly with a unified size, the top of the clamping assembly is matched and installed with the positioning machine tool through the lock buckle type design (that is, the fixed clamping groove of the equipment fixing part is fixedly connected with the lock buckle type of the control equipment), the consistency of the collection results of different component elastic waves is ensured, and the positioning error of the solid model collected by different components is less than 0.1 mm; through loading the solid physical simulation observation equipment on the high-precision three-coordinate positioning machine tool, the positioning error of the longitudinal and transverse wave probe at any position in the three-dimensional space can be less than 0.01 mm, and the three-dimensional space positioning accuracy of the collection of the elastic wave of the solid model can be improved by more than 5 times compared with the prior art.
