Description

Technical Field

[0001] The present invention belongs to the technical field of surveying devices, and more particularly, relates to a soil profile acoustic wave surveying device. Background Art

[0002] In geological surveys, the probe in an acoustic logging instrument can be used to transmit sound waves into the soil and receive the returned sound waves. Since sound waves propagate at different speeds in different soil types, they can be used to survey the soil. The acoustic time difference curve reflects the differences in soil physical properties, allowing for identification of soil types and assisting in soil stratification and classification. Some geological surveys require excavating soil profiles, and naturally formed soil profiles also exist in nature. However, the market currently lacks a device capable of performing acoustic surveys of soil profiles. Summary of the Invention

[0003] The purpose of the present invention is to provide a soil profile acoustic wave survey device, aiming to solve the problem that there is a lack of a device capable of performing acoustic wave survey on soil profiles on the market.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a soil profile acoustic wave survey device is provided, comprising a vehicle body, a supporting member, a first drive assembly, a shielding container, a second drive assembly, and an acoustic well logging instrument. The supporting member is connected to the vehicle body in a horizontal sliding direction. The first drive assembly is arranged on the vehicle body and is used to drive the supporting member to slide. The shielding container is connected to the supporting member and can be raised and lowered. One end of the shielding container along the sliding direction of the supporting member is an open end, and the open end of the shielding container can penetrate into or exit the soil profile as the supporting member slides. The second drive assembly is arranged on the supporting member and is used to drive the shielding container to rise and fall. The probe of the acoustic well logging instrument is located in the shielding container and is connected to the shielding container.

[0005] In one possible implementation, the soil profile acoustic wave survey device further includes two connecting units, each comprising a sliding shaft, a sleeve, a lifting shaft, and a fixed tube. The sliding shaft is arranged along the sliding direction of the support member, slides through the vehicle body, and is fixedly connected to the support member. The sleeve is arranged vertically and fixedly connected to the sliding shaft. The lifting shaft slides through the sleeve. The fixed tube is fixedly connected to both the lifting shaft and the shielding container.

[0006] In a possible implementation, the lifting shaft is provided with a filling hole coaxially arranged with the lifting shaft, the filling hole is communicated with the interior of the fixing tube, one end of the fixing tube is closed, and the other end is communicated with the interior of the shielding container.

[0007] In one possible implementation, the lifting shaft is split along its length, including a fixed section for fixedly connecting to the fixed tube and multiple split sections. The top surfaces of the fixed section and the split sections are both provided with threaded holes, and the bottom of the split sections has a threaded portion, which is threadedly connected to the adjacent threaded holes.

[0008] In one possible implementation, the connecting unit further includes a filling funnel, the bottom of which is inserted into the uppermost threaded hole and provided with an exposed thread threadedly connected to the threaded hole, and the outer diameter of the upper portion of the filling funnel is larger than the outer diameter of the lifting shaft.

[0009] In one possible implementation, the soil profile acoustic wave survey device further includes a sliding tube and a third drive assembly. The sliding tube is vertically disposed and slides through the top wall of the shielding container. A docking member is sleeved and fixed to the outside of the sliding tube. The third drive assembly is disposed on the shielding container and is configured to drive the sliding tube to slide. The upper end of the probe is inserted and fixed within the sliding tube.

[0010] In one possible implementation, the soil profile acoustic survey device further includes positioning rods, a fixing member, and a fourth drive assembly. Multiple positioning rods are vertically disposed and slidably extend through the vehicle body. The fixing member is fixedly connected to each of the multiple positioning rods. The fourth drive assembly is disposed on the vehicle body and is configured to drive the fixing member upward and downward, thereby enabling the positioning rods to be inserted into or removed from the ground.

[0011] In one possible implementation, the top surface of the fixing member is provided with a receiving groove, and the soil profile acoustic wave survey device further includes a supporting frame, a filter screen, a liquid inlet pipe, a liquid pump and a liquid outlet pipe. The supporting frame is located in the receiving groove, and the supporting frame is horizontally arranged and fixed to the inner side surface of the receiving groove in a circumferential direction. The filter screen covers the supporting frame and is fixed to the supporting frame so that the receiving groove has a storage space located below the filter screen. One end of the liquid inlet pipe is fixedly connected to the fixing member and communicates with the storage space. The liquid pump is fixed on the fixing member, and the inlet of the liquid pump is connected to the other end of the liquid inlet pipe. One end of the liquid outlet pipe is connected to the outlet of the liquid pump.

[0012] In one possible implementation, the soil profile acoustic wave survey device further includes a filling tube, a filling hose, and an elastic plug. The filling tube has a U-shaped structure, comprising a first section and a second section that are parallel to each other. The ends of the filling hose are connected to the free end of the liquid outlet tube and the end of the filling tube located on the second section, respectively. The elastic plug is sleeved and fixed to the outside of the first section and is inserted into one of the filling funnels, so that the end of the filling tube located on the first section reaches the filling funnel.

[0013] In one possible implementation, the soil profile acoustic wave survey device further includes a cover plate, a limit frame, two columns, and two limit shafts. The cover plate is horizontally arranged and located above the fixing member. The limit frame is horizontally arranged and fixedly attached to the bottom surface of the cover plate. Both columns are fixedly connected to the limit frame. Two limit shafts are respectively fixedly connected to the two columns, and the limit shafts are horizontally arranged and slidably penetrate the vehicle body. The raising and lowering of the fixing member can cause the fixing member to slide into or out of the limit frame.

[0014] In this embodiment of the present application, the vehicle moves to position the device near the top of the soil profile. The first drive assembly then drives the support member to slide, causing the shielding container to reach the outward side of the soil profile. The second drive assembly then lowers the shielding container to a suitable position. The first drive assembly then drives the support member to slide, inserting the open end of the shielding container into the soil profile. At this point, the probe within the shielding container transmits sound waves into the soil profile and receives the return sound waves from within, thereby performing an acoustic survey of the soil profile. This avoids the current lack of devices capable of performing acoustic surveys of soil profiles on the market. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0035] Please also refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 10 The soil profile acoustic wave survey device provided by the present invention will now be described. The soil profile acoustic wave survey device includes a vehicle body 1, a supporting member 2, a first drive assembly 3, a shielding container 4, a second drive assembly 5, and an acoustic well logging instrument. The supporting member 2 is connected to the vehicle body 1 in a horizontal sliding direction. The first drive assembly 3 is provided on the vehicle body 1 and is used to drive the supporting member 2 to slide. The shielding container 4 is connected to the supporting member 2 and can be raised and lowered. One end of the shielding container 4 along the sliding direction of the supporting member 2 is an open end. The open end of the shielding container 4 can penetrate into or exit the soil profile 270 as the supporting member 2 slides. The second drive assembly 5 is provided on the supporting member 2 and is used to drive the shielding container 4 to rise and fall. The probe 61 of the acoustic well logging instrument is located in the shielding container 4 and is connected to the shielding container 4.

[0036] Compared to the prior art, the soil profile acoustic wave survey device provided by the present invention utilizes a vehicle body 1 to move the device to a location near the top of soil profile 270. The first drive assembly 3 then drives the support member 2 to slide, causing the shielding container 4 to reach the outward side of soil profile 270. The second drive assembly 5 then drives the shielding container 4 down to a suitable position. The first drive assembly 3 then drives the support member 2 to slide, inserting the open end of the shielding container 4 into soil profile 270. At this point, the probe 61 within the shielding container 4 transmits acoustic waves toward soil profile 270 and receives acoustic waves returning from within soil profile 270, thereby performing an acoustic survey of soil profile 270. This eliminates the current market shortage of devices capable of performing acoustic surveys of soil profile 270.

[0037] In the prior art, the acoustic logging instrument also includes a host and a cable. The host and the probe 61 are electrically connected via the cable. The host receives and analyzes the signal transmitted by the probe 61. In this embodiment, the host can be fixed to the vehicle body 1. The host and the cable are not shown in the drawings.

[0038] Furthermore, a sound absorber may be provided in the shielding container 4 to absorb other sound waves, thereby preventing these sound waves from affecting the survey.

[0039] Furthermore, the first driving assembly 3 is fixed on the vehicle body 1 and has a first telescopic rod that can be extended and retracted along the sliding direction of the supporting member 2, and the first telescopic rod is fixedly connected to the supporting member 2, and the supporting member 2 is driven to slide by the extension and retraction of the first telescopic rod.

[0040] In this embodiment, the first driving assembly 3 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0041] Furthermore, the second drive component 5 can adopt a winch, which is fixed on the supporting member 2 and the rope in the winch is fixedly connected to the shielding container 4. The shielding container 4 is driven to rise and fall by the retraction and extension of the rope. A guide wheel can be provided on the supporting member 2, and the rope is guided by the guide wheel to form a vertical section for fixed connection with the shielding container 4.

[0042] In some embodiments, see Figures 1 to 3The soil profile acoustic wave survey device also includes two connecting units, which include a sliding shaft 71, a sleeve 72, a lifting shaft 73 and a fixed tube 74. The sliding shaft 71 is arranged along the sliding direction of the supporting member 2, and the sliding shaft 71 is slidably inserted into the vehicle body 1. The sliding shaft 71 is fixedly connected to the supporting member 2. The sleeve 72 is vertically arranged and fixedly connected to the sliding shaft 71. The lifting shaft 73 is slidably inserted into the sleeve 72. The fixed tube 74 is fixedly connected to both the lifting shaft 73 and the shielding container 4. The supporting member 2 is slidably connected to the vehicle body 1 through the sliding shaft 71, and the shielding container 4 is slidably connected to the supporting member 2 and can be raised and lowered through the sliding cooperation of the lifting shaft 73 and the sleeve 72.

[0043] In some embodiments, see Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 and Figure 9 The lifting shaft 73 is provided with a filling hole 7301 coaxially disposed therewith. The filling hole 7301 communicates with the interior of the fixed tube 74, which is sealed at one end and communicates with the interior of the shielding container 4 at the other end. Liquid is injected into the filling hole 7301, and the liquid flows through the filling hole 7301 into the fixed tube 74 and then into the shielding container 4 until the shielding container 4 is filled with liquid. This discharges the gas within the shielding container 4, replacing the gas between the probe 61 and the soil profile 270 with liquid. This reduces the attenuation of sound waves transmitted and received by the probe 61. The attenuation of sound waves propagating in liquid is less than that of sound waves propagating in air.

[0044] In some embodiments, see Figures 9 to 12 The lifting shaft 73 is split along its length, including a fixed section 731 for fixed connection with the fixed tube 74 and a plurality of split sections 732. The top surfaces of the fixed section 731 and the split section 732 are both provided with threaded holes 7302, and the bottom of the split section 732 has a threaded portion 7303. The threaded portion 7303 is threadedly connected to the adjacent threaded hole 7302, so that the fixed section 731 and the adjacent split section 732, and the two adjacent split sections 732 are all detachably connected. When the device is used, the lifting shaft 73 is slid upward until the fixed section 731 slides into the sleeve 72, and then the plurality of split sections 732 are removed from the fixed section 731 and the plurality of split sections 732 are disassembled one by one. In this way, the overall height of the device can be reduced, thereby facilitating the transportation of the device. Moreover, the length of the split section 732 is relatively small, which is convenient for storage. In this embodiment, a suitable number of split sections 732 may be selected to assemble the lifting shaft 73 according to the height of the soil profile 270 .

[0045] In some embodiments, see Figure 1 、 Figure 5 and Figure 10 The connecting unit also includes a filling funnel 75. The bottom of the filling funnel 75 is inserted into the uppermost threaded hole 7302 and has an exposed thread that is threadedly connected to the threaded hole 7302. The outer diameter of the upper portion of the filling funnel 75 is larger than the outer diameter of the lifting shaft 73. Liquid is poured into the filling hole 7301 through the filling funnel 75. In addition, if a fault causes the lifting shaft 73 to slide freely, such as a winch rope breakage, the upper portion of the filling funnel 75 is limited by the sleeve 72 to prevent the lifting shaft 73 from sliding off the sleeve 72, thereby improving the safety of the device to a certain extent.

[0046] In some embodiments, see Figure 7 The soil profile acoustic wave survey device also includes a sliding tube 8 and a third driving assembly 9. The sliding tube 8 is vertically arranged and slides through the top wall of the shielding container 4. The docking piece is fixed on the outside of the sliding tube 8. The third driving assembly 9 is arranged on the shielding container 4 and is used to drive the sliding tube 8 to slide. Among them, the upper end of the probe 61 is passed through and fixed in the sliding tube 8. When performing acoustic wave survey on the soil profile 270, it is necessary to move the probe 61 in the vertical direction, so as to change the position of the probe 61 to continuously perform acoustic wave survey. At this time, the third driving assembly 9 can drive the sliding tube 8 to slide, thereby driving the probe 61 to rise and fall.

[0047] In this embodiment, the cable in the sonic logging tool can pass through the sliding tube 8 .

[0048] Furthermore, the third driving assembly 9 is fixed on the shielding container 4 and has a second telescopic rod that can be extended and retracted in the vertical direction. The second telescopic rod is fixedly connected to the sliding tube 8, and the sliding tube 8 is driven to slide by the extension and retraction of the second telescopic rod.

[0049] In this embodiment, the third driving assembly 9 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0050] Furthermore, the top wall of the shielding container 4 is provided with a groove, into which the third drive assembly 9 is inserted, thereby providing a degree of protection for the third drive assembly 9. The groove reduces the volume within the shielding container 4, making it easier to fill the shielding container 4 with liquid. In this embodiment, two sets of grooves and third drive assemblies 9 can be provided. Furthermore, an intermediate member 260 can be mounted and fixedly mounted on the outside of the sliding tube 8. The intermediate member 260 is fixedly connected to the two second telescopic rods, thereby indirectly achieving a fixed connection between the two second piston rods and the sliding tube 8.

[0051] In some embodiments, see Figure 1 、 Figure 6 and Figure 13The soil profile acoustic wave survey device also includes a positioning rod 10, a fixing member 110 and a fourth drive assembly 120. There are multiple positioning rods 10, and the positioning rods 10 are vertically arranged and slidably penetrated into the vehicle body 1. The fixing member 110 is fixedly connected to the multiple positioning rods 10. The fourth drive assembly 120 is arranged on the vehicle body 1 and is used to drive the fixing member 110 to rise and fall so that the positioning rods 10 can penetrate into the ground or be pulled out from the ground. When the fourth drive assembly 120 drives the fixing member 110 to descend so that the lower ends of the multiple positioning rods 10 penetrate into the ground, the movement of the device can be restricted. In this way, when the open end of the shielding container 4 penetrates into the soil profile 270, it can be avoided that the vehicle body 1 moves forward under the action of the reaction force, thereby avoiding the risk of the device falling from the soil profile 270.

[0052] In this embodiment, the lower end of the positioning rod 10 may be pointed, so that the positioning rod 10 can be easily penetrated into the ground.

[0053] Furthermore, the fourth driving assembly 120 is fixed on the vehicle body 1 and has a third telescopic rod that can be extended and retracted in the vertical direction, and the third telescopic rod is fixedly connected to the fixing member 110, and the fixing member 110 is driven to rise and fall by the extension and retraction of the third telescopic rod.

[0054] In this embodiment, the fourth driving assembly 120 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0055] In some embodiments, see Figure 1 、 Figure 4 、 Figure 6 and Figure 13The top surface of the fixing member 110 is provided with a receiving groove 1101. The soil profile acoustic wave survey device also includes a support frame 1501, a filter screen 1502, a liquid inlet pipe 160, a liquid pump 170, and a liquid outlet pipe 180. The support frame 1501 is positioned within the receiving groove 1101, horizontally arranged and circumferentially secured to the inner surface of the receiving groove 1101. The filter screen 1502 covers the support frame 1501 and is secured to the support frame 1501, so that the receiving groove 1101 defines a storage space 11011 below the filter screen 1502. One end of the liquid inlet pipe 160 is fixedly connected to the fixing member 110 and communicates with the storage space 11011. The liquid pump 170 is fixedly mounted on the fixing member 110, with the inlet of the liquid pump 170 connected to the other end of the liquid inlet pipe 160. One end of the liquid outlet pipe 180 is connected to the outlet of the liquid pump 170. Storage space 11011 is used to store liquid. Liquid pump 170 can pump liquid from storage space 11011 through liquid inlet pipe 160, then discharge it through liquid outlet pipe 180. The liquid discharged from outlet pipe 180 is then injected into filling hole 7301. Filter screen 1502 prevents impurities from entering storage space 11011. After use of the device, the disassembled segment 732 can be placed onto filter screen 1502 in receiving tank 1101. Support frame 1501 supports segment 732 via filter screen 1502.

[0056] In some embodiments, see Figure 1 、 Figure 3 and Figure 4 The soil profile acoustic wave survey device also includes a filling tube 190, a filling hose 200, and an elastic plug 210. The filling tube 190 has a U-shaped structure, comprising a first section 1901 and a second section 1902, which are parallel to each other. The ends of the filling hose 200 are connected to the free end of the liquid outlet tube 180 and the end of the filling tube 190 located on the second section 1902, respectively. The elastic plug 210 is mounted and fixed to the outside of the first section 1901. The elastic plug 210 is inserted into one of the filling funnels 75, so that the end of the filling tube 190 located on the first section 1901 reaches the filling funnel 75. A worker can hold the second section 1902 and insert the elastic plug 210 into one of the filling funnels 75. The elastic deformation of the elastic plug 210 compresses the filling funnel 75, thereby preventing the elastic plug 210 from exiting the filling funnel 75. The worker can then release the second section 1902. The liquid coming out of the liquid outlet pipe 180 flows into the filling funnel 75 through the filling hose 200 and the filling pipe 190.

[0057] When the device is idle, the first section 1901 can be slid into the supporting member 2 so that the supporting member 2 supports the filling tube 190 through the elastic plug 210 .

[0058] In some embodiments, see Figure 1 、 Figure 6 and Figure 13 The soil profile acoustic wave survey device also includes a cover plate 220, a limit frame 230, two columns 240 and two limit shafts 250. The cover plate 220 is horizontally arranged and located above the fixing member 110. The limit frame 230 is horizontally arranged and fixedly mounted on the bottom surface of the cover plate 220. The two columns 240 are fixedly connected to the limit frame 230. The two limit shafts 250 are respectively fixedly connected to the two columns 240, and the limit shafts 250 are horizontally arranged and slidably penetrated into the vehicle body 1. Among them, the lifting and lowering of the fixing member 110 can enable the fixing member 110 to slide into or out of the limit frame 230. After the multiple split segments 732 are placed on the filter screen 1502 in the accommodating groove 1101, the fourth driving assembly 120 drives the fixing member 110 to move upward, thereby pulling the positioning rod 10 out of the ground until the fixing member 110 slides into the limit frame 230. In this way, the cover plate 220 can cover the upper end of the receiving groove 1101, thereby preventing the split section 732 from being lost. At this time, the limiting of the limit frame 230 by the fixing member 110 can limit the sliding of the limit shaft 250, thereby preventing the limit shaft 250 from sliding out of the vehicle body 1. When the present device is in use, the fourth drive assembly 120 drives the fixing member 110 to slide downward to exit the limit frame 230 until the positioning rod 10 penetrates the ground, and then drives the limit shaft 250 to slide out of the vehicle body 1, so that the cover plate 220 can be removed. At this time, the height of the fixing member 110 is relatively low and there is no cover of the cover plate 220, which makes it convenient to remove the split section 732 from the receiving groove 1101.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
