Description

Technical Field

[0001] This invention relates to the field of seismic testing equipment technology, and in particular to a seismic testing device. Background Technology

[0002] Acoustic imagers are based on microphone array measurement technology. By measuring the phase difference of the sound waves arriving at each microphone in a certain space, the location of the sound source is determined according to the phase array principle. The amplitude of the sound source is measured and the distribution of the sound source in space is displayed in the form of an image, that is, a spatial sound field distribution cloud map - acoustic image map is obtained, in which the color and brightness of the image represent the intensity.

[0003] Typically, acoustic imagers undergo seismic resistance testing after manufacturing to ensure their quality before leaving the factory. However, current seismic resistance testing devices rely on a single method, often using reciprocating shaking, which fails to accurately reflect the operating environment of the acoustic imager, resulting in low accuracy and limited applicability of the test results. Summary of the Invention

Detailed Implementation

[0030] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Please see Figure 1This application provides an embodiment of a seismic testing device 10, comprising: a placement component 110, a clamping mechanism 120, and a testing mechanism 130. The placement component 110 includes a fixed plate 111 and a movable plate 112. One end of the movable plate 112 is rotatably mounted on the fixed plate 111 about a first direction. The movable plate 112 supports an acoustic imaging device 20. The clamping mechanism 120 is mounted on the movable plate 112 and is used to clamp the acoustic imaging device 20. The testing mechanism 130 includes a swing assembly 131 and a vibration assembly 132. The swing assembly 131 is connected to the fixed plate 111 and can drive the placement component 110 to reciprocate along a second direction. The vibration assembly 132 drives the movable plate 112 to rotate relative to the fixed plate 111 about a first direction.

[0032] In the aforementioned seismic testing device, the placement component 110 includes a fixed plate 111 and a movable plate 112 that are rotatably connected. The swing component 131 is connected to the fixed plate 111 and can drive the placement component 110 to reciprocate along the second direction. The vibration component 132 can drive the movable plate 112 to rotate relative to the fixed plate 111 along the first direction. The movable plate 112 can simulate a complex vibration environment under the combination and superposition of the two motion modes. Therefore, it can provide a more accurate simulation of the use environment for the acoustic imager 20 placed on the movable plate 111, thereby improving the detection accuracy of the testing device.

[0033] Specifically, in this embodiment, the second direction is the horizontal direction.

[0034] To facilitate a clear understanding of the setting directions of the first steering and the second direction in this embodiment, Figure 1 For example, the first turn is Figure 1 The direction indicated by S1 is the second direction. Figure 1 The direction indicated in S2.

[0035] To avoid accidental contact with the testing mechanism 130 and extend its service life, in one embodiment, such as... Figure 1 As shown, the seismic testing device 10 also includes a mounting box 140. This allows a portion of the swing assembly 131 and a portion of the vibration assembly 132 to be installed within the mounting box 140, providing a favorable working environment.

[0036] Specifically, in this embodiment, such as Figure 1 and Figure 2As shown, the swing assembly 131 includes a first motor 1311 and a support bracket 1312. The support bracket 1312 has a through hole 13121. A first rack 1313 and a second rack 1314 are respectively provided on two opposite side walls of the through hole 13121, with the length directions of both racks parallel to a second direction. The first motor 1311 is placed inside the mounting box 140. A drive gear 1315 is provided on the output shaft of the first motor 1311. The drive gear 1315 can be inserted into the through hole 13121 and meshes with the first rack 1313 and the second rack 1314 for transmission. A limiting hole 141 is provided at the top of the mounting box 140, through which the support bracket 1312 passes and connects to the fixing plate 111. Thus, when the first motor 1311 starts, the drive gear 1315 can mesh with the first rack 1313 and the second rack 1314 in sequence, thereby enabling the support bracket 1312 to move back and forth in the second direction.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, in one embodiment, the support bracket 1312 includes a first rod 13122, a second rod 13123, and a roller 13124. The first rod 13122 is arranged along a second direction, and a through hole 13121 is provided on the first rod 13122. The second rod 13123 passes through the first rod 13122 and is connected to the roller 13124, which is slidably disposed on the bottom wall of the mounting box 140. One end of the second rod 13123 away from the roller 13124 passes through a limiting hole 141 and is connected to a fixing plate 111. In this way, the second rod 13123 can provide stable support for the reciprocating movement of the first rod 13122 along the second direction, and at the same time, it can also transmit the reciprocating movement of the first rod 13122 in the second direction to the fixing plate 111, so that the fixing plate 111 can also drive the movable plate 112 to reciprocate in the second direction. Since the roller 13124 can slide inside the mounting box 140, the friction between the second rod 13123 and the bottom of the mounting box 140 can be reduced.

[0038] In one embodiment, such as Figure 1 As shown, the wall of the limiting hole 141 is provided with a limiting groove 1411. The second rod 13123 is provided with a limiting block 13125, which can slide within the limiting groove 1411. In this way, the second rod 13123 can be limited to prevent it from dislodging from the limiting hole 141 and affecting the horizontal swaying of the object 110.

[0039] Since the acoustic imager 20 may be subjected to vibrations from multiple directions during actual use, in order to further simulate the operating environment of the acoustic imager 20, in one embodiment, such as... Figure 1 and Figure 3As shown, the vibration assembly 132 abuts against the movable plate 112, allowing the movable plate 112 to rotate along a first direction, switching between a first state and a second state. In the first state, the movable plate 112 is in contact with and stacked with the fixed plate 111. In the second state, the movable plate 112 and the fixed plate 111 are set at an angle. Thus, as the movable plate 112 continuously switches between the first and second states, the acoustic imager 20 mounted on the movable plate 112 can move along with it, thereby recreating the operating environment of the acoustic imager 20 and improving the detection accuracy of the seismic resistance testing device 10.

[0040] In one embodiment, such as Figure 1 and Figure 3 As shown, the vibration assembly 132 includes a second motor 1321 and a contact rod 1322. The second motor 1321 is housed within the mounting box 140. The output shaft of the second motor 1321 is arranged along a second direction. The output shaft of the second motor 1321 passes through the mounting box 140 and connects to the contact rod 1322, with the contact rod 1322 and the output shaft of the second motor 1321 arranged at an angle. The contact rod 1322 is rotatable around the output shaft of the second motor 1321 and can engage with the movable plate 112, allowing the movable plate 112 to reciprocate in a first direction to switch between a first state and a second state.

[0041] Specifically, when the movable plate 112 is in the first state, its length is greater than that of the fixed plate 111. The abutment rod 1322 is located below the object 110, and it can abut against the area of ​​the movable plate 112 that extends beyond the fixed plate 111. When the movable plate 112 is in the first state, the abutment rod 1322 is separated from the movable plate 112, and the movable plate 112 is stacked and attached to the fixed plate 111. When the movable plate 112 is in the second state, the abutment rod 1322 abuts against the movable plate 112, and the movable plate 112 is raised and angled with the fixed plate 111. Thus, when the output shaft of the second motor 1321 rotates, the abutment rod 1322 can abut against and raise the movable plate 112 or separate from it, thereby causing the movable plate 112 to repeatedly switch between the first and second states. In other words, the movable plate 112 is repeatedly raised to achieve its rotation in the first direction.

[0042] To prevent the movable plate 112 from causing excessive impact on the fixed plate 111 when switching from the second state to the first state, thus affecting the service life of both, as follows: Figure 1 As shown, in this embodiment, the side of the fixed plate 111 facing the movable plate 112 is provided with a buffer pad 113.

[0043] To improve the applicability of the vibration assembly 132, in one embodiment, such as Figure 1 and Figure 3 As shown, the vibration assembly 132 also includes a turntable 1323, a locking nut 1324, and a slide rod 1325. The turntable 1323 is mounted on the output shaft of the second motor 1321, and the turntable 1323 has a groove 13231. The direction of the groove 13231 intersects the axial direction of the output shaft of the second motor 1321. The slide rod 1325 is slidably disposed in the groove 13231 and connected to the abutment rod 1322. The outer wall of the slide rod 1325 has external threads, and the locking nut 1324 is sleeved on the outside of the slide rod 1325. The diameter of the locking nut 1324 is larger than the width of the groove 13231, and the locking nut 1324 can be screwed relative to the slide rod 1325 until the locking nut 1324 and the turntable 1323 are in a pressing fit. Thus, when it is necessary to adjust the vibration amplitude of the vibration component 132, the position of the slide rod 1325 within the slide groove 13231 can be adjusted to adjust the length of the protrusion of the abutment rod 1322 relative to the turntable 1323. Specifically, when it is necessary to increase the amplitude of the rotation of the movable plate 112 along the first direction, the slide rod 1325 can drive the abutment rod 1322 to move closer to the output shaft of the second motor 1321 within the slide groove 13231; when it is necessary to decrease the amplitude of the rotation of the movable plate 112 along the first direction, the slide rod 1325 can drive the abutment rod 1322 to move further away from the output shaft of the second motor 1321 within the slide groove 13231. In this way, the vibration amplitude of the vibration resistance detection device 10 can be adjusted, improving its applicability.

[0044] Alternatively, in other embodiments, the abutment rod 1322 is a telescopic rod with a telescopic function. In this way, the vibration amplitude of the vibration component 132 can also be adjusted.

[0045] In one embodiment, such as Figure 3 As shown, the end of the abutment rod 1322 that abuts against the movable plate 112 is movably equipped with a ball bearing 1326. This reduces the friction between the movable plate 112 and the abutment rod 1322.

[0046] In one embodiment, such as Figure 1 As shown, the mounting box 140 contains a battery 150 and a PCB board 160. A control panel 170, electrically connected to the PCB board 160, is mounted on the outer wall of the mounting box 140. The battery 150 is electrically connected to the first motor 1311 and the second motor 1321, primarily for supplying power to both motors. The PCB board 160 is electrically connected to both the first motor 1311 and the second motor 1321. Thus, operators can directly control the testing mechanism 130 via the control panel 170.

[0047] Furthermore, to prevent the testing mechanism 130 from causing equipment such as the mounting box 140 to jump or shift during operation, such as Figure 1As shown, in one embodiment, a counterweight 180 is provided at the bottom of the mounting box 140.

[0048] Please see Figure 1 , Figure 4 and Figure 5 In one embodiment, the clamping mechanism 120 includes a first clamping member 121, a second clamping member 122, and a driving member 123. The driving member 123 is linked to the first clamping member 121 and the second clamping member 122, and can drive the first clamping member 121 and the second clamping member 122 to move closer or further apart. A clamping space for clamping the acoustic imager 20 is formed between the first clamping member 121 and the second clamping member 122. Therefore, when the acoustic imager 20 needs to be detected, it can be directly placed in the clamping space, and the driving member 123 can control the first clamping member 121 and the second clamping member 122 to move closer to each other to achieve the effect of quickly clamping the acoustic imager 20.

[0049] Since the movable plate 112 can support the acoustic imager 20, when the acoustic imager 20 is placed in the clamping space, in addition to being clamped by the first clamping member 121 and the second clamping member 122, it can also be supported by the movable plate 112. In this way, the stability of the acoustic imager 20 placed on the shock resistance detection device 10 is better.

[0050] In one embodiment, please refer to Figures 4 to 6 The driving component 123 includes a driving block 1231, a first slider 1232, and a second slider 1233. The driving block 1231 has a frustum-shaped structure. Along the radial direction of the driving block 1231, the first clamping member 121 and the second clamping member 122 are located on opposite sides of the driving block 1231. The side of the first clamping member 121 facing the driving block 1231 is a first inclined surface 1211, and a first guide portion 1212 is provided on the first inclined surface 1211. The side of the second clamping member 122 facing the driving block 1231 is a second inclined surface 1221, and a second guide portion is provided on the second inclined surface 1221. The guiding directions of both the first guide portion 1212 and the second guide portion are parallel to the generatrix of the driving block 1231. The first slider 1232 is slidably disposed on the first guide portion 1212 and connected to the driving block 1231, and the second slider 1233 is slidably disposed on the second guide portion and connected to the driving block 1231. Thus, when the drive block 1231 moves along its axial direction, under the action of the first slider 1232 and the second slider 1233, the first clamping member 121 and the second clamping member 122 can move closer to each other or further away from each other.

[0051] Specifically, in this embodiment, the axial direction of the driving block 1231 is parallel to the second direction, and the diameter of the end of the driving block 1231 away from the clamping space is larger than the diameter of the end of the driving block 1231 near the clamping space. Thus, when the driving block 1231 approaches the clamping space along its axial direction, the first clamping member 121 and the second clamping member 122 move away from each other; when the driving block 1231 moves away from the clamping space along its axial direction, the first clamping member 121 and the second clamping member 122 move closer to each other.

[0052] Optionally, the first guide portion 1212 may be a first guide rail protruding from the first inclined surface 1211, and the second guide portion may be a second guide rail protruding from the second inclined surface 1221. Alternatively, the first guide portion 1212 may be a first guide groove recessed on the first inclined surface 1211, and the second guide portion may be a second guide groove recessed on the second inclined surface 1221.

[0053] Further, in one embodiment, please refer to Figure 4 and Figure 5 The clamping mechanism 120 also includes a mounting bracket 124 and a push rod 125. The mounting bracket 124 is mounted on the movable plate 112. The mounting bracket 124 has a through hole with internal threads on its inner wall. The push rod 125 has external threads on its outer wall and passes through the through hole to be rotatably connected to the drive block 1231. In this way, the drive component 123, the first clamping component 121, and the second clamping component 122 can be securely mounted on the movable plate 112 via the mounting bracket 124.

[0054] Specifically, the length direction of the push rod 125 is parallel to the axial direction of the drive block 1231. When the push rod 125 is rotated clockwise, it moves and pushes the drive block 1231 toward the direction closer to the clamping space, causing the first clamping member 121 and the second clamping member 122 to move away from each other. When the push rod 125 is rotated counterclockwise, it moves and pulls the drive block 1231 toward the direction away from the clamping space, causing the first clamping member 121 and the second clamping member 122 to move closer to each other. Therefore, the installation or removal of the acoustic imager 20 is relatively convenient, requiring only the rotation of the push rod 125.

[0055] Furthermore, to facilitate the rotation of push rod 125, such as Figure 5 As shown, a handwheel 126 is provided at the end of the push rod 125 away from the drive block 1231.

[0056] To improve the stability when the first clamping member 121 and the second clamping member 122 move relative to each other, please refer to Figure 4 and Figure 5In one embodiment, the clamping mechanism 120 further includes a first guide rod assembly 127 and a second guide rod assembly 128. The mounting bracket 124 includes a first baffle 1241, a connecting plate 1242, and a second baffle 1243. The first baffle 1241 and the second baffle 1243 are opposite to and spaced apart on the connecting plate 1242. A through hole is provided on the connecting plate 1242. Both the first baffle 1241 and the second baffle 1243 are provided with guide holes. The first guide rod assembly 127 is slidably disposed within the guide hole on the first baffle 1241 and connected to the first clamping member 121. The second guide rod assembly 128 is slidably disposed within the guide hole on the second baffle 1243 and connected to the second clamping member 122. Thus, when the first clamping member 121 and the second clamping member 122 move relative to each other, wobbling during movement can be avoided.

[0057] In one embodiment, such as Figure 4 and Figure 5 As shown, both the first clamping member 121 and the second clamping member 122 include a base 1213 and a clamping arm assembly 1214 connected to each other. The side of the base 1213 in the first clamping member 121 facing the driving block 1231 is a first inclined surface 1211, and the side of the base 1213 in the second clamping member 122 facing the driving block 1231 is a second inclined surface 1221. A clamping space is formed between the two clamping arm assemblies 1214.

[0058] Specifically, in this embodiment, such as Figure 4 and Figure 5 As shown, the clamping arm assembly 1214 includes a rotating rod 12141, a first clamping plate 12142, and a second clamping plate 12143. The length direction of the rotating rod 12141 is parallel to the radial direction of the drive block 1231, and the rotating rod 12141 is rotatably mounted on the base 1213. The first clamping plate 12142 and the second clamping plate 12143 are respectively located at both ends of the rotating rod 12141. The first clamping plate 12142 is an arc-shaped panel with its opening facing the clamping space, and the second clamping plate 12143 is a flat plate. In this way, the first clamping plate 12142 or the second clamping plate 12143 can be selected for clamping according to the shape of the acoustic imager 20, thereby improving the stability of the clamping of the first clamping member 121 and the second clamping member 122, and also increasing the applicability of the clamping mechanism 120.

[0059] Specifically, when using this seismic testing device 10, the acoustic imager 20 can be placed on the movable plate 112 and clamped between the first clamping member 121 and the second clamping member 122 by the driving member 123. The first motor 1311 and the second motor 1321 are then turned on. When the first motor 1311 starts, the drive gear 1315 reciprocates in sequence with the first rack 1313 and the second rack 1314 on the support bracket 1312, causing the support bracket 1312 to move back and forth in the horizontal direction. Ultimately, this causes the fixed plate 111 to drive the acoustic imager 20 on the movable plate 112 to sway left and right in the horizontal direction. The second motor 1321 starts, driving the turntable 1323 to rotate around the output shaft of the second motor 1321. The abutment rod 1322 set on the turntable 1323 rotates with the turntable 1323. Thus, the abutment rod 1322 abuts against the movable plate 112, causing the movable plate 112 to rise in the longitudinal direction, or the abutment rod 1322 separates from the movable plate 112, causing the movable plate 112 to be raised in the longitudinal direction and then fall downward. In other words, the movable plate 112 repeatedly switches between the first state and the second state to achieve vibration in the longitudinal direction.

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0061] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0062] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0063] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
