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

[0023] Please also read Figure 1 , Figure 2 , Figure 6 and Fig.10 Now, the soil profile acoustic wave survey device provided by the present invention is described. The soil profile acoustic wave survey device comprises a vehicle body 1, a supporting member 2, a first driving assembly 3, a shielding container 4, a second driving assembly 5 and an acoustic well logging instrument. The supporting member 2 is connected to the vehicle body 1 in a sliding manner in the horizontal direction. The first driving assembly 3 is arranged 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 driving assembly 5 is arranged 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.

[0024] Compared with the prior art, the soil profile acoustic wave survey device provided by the present invention is that the vehicle body 1 is moved so that the device reaches the attachment at the top of the soil profile 270, and then the first driving component 3 drives the supporting member 2 to slide, so that the shielding container 4 reaches the outer side of the soil profile 270, and then the second driving component 5 drives the shielding container 4 to descend to a suitable position, and then the first driving component 3 drives the supporting member 2 to slide, so that the open end of the shielding container 4 is inserted into the soil profile 270. At this time, the probe 61 in the shielding container 4 emits sound waves to the soil profile 270 and receives the sound waves returned from the soil profile 270, so as to perform acoustic wave survey on the soil profile 270, thereby avoiding the problem that there is a lack of a device capable of performing acoustic wave survey on the soil profile 270 in the current market.

[0025] In the prior art, the sonic logging instrument further includes a host and a cable, the host and the probe 61 are electrically connected via the cable, and the host receives and analyzes the signal transmitted by the probe 61. In this embodiment, the host can be fixed on the vehicle body 1. The host and the cable are not shown in the drawings.

[0026] Furthermore, a sound absorber may be provided in the shielding container 4, and the sound absorber is used to absorb other sound waves, thereby avoiding the influence of these sound waves on the survey.

[0027] 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.

[0028] In this embodiment, the first driving assembly 3 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0029] Furthermore, the second driving 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 release of the rope. A guide wheel can be set 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.

[0030] In some embodiments, see Figures 1 to 3The soil profile acoustic wave survey device also includes two connection units, and the connection units 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 penetrated in the vehicle body 1, and 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 penetrated in 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 lifted and lowered through the sliding cooperation of the lifting shaft 73 and the sleeve 72.

[0031] In some embodiments, see Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 The lifting shaft 73 is provided with a filling hole 7301 coaxially arranged with the lifting shaft 73. The filling hole 7301 is connected with the fixed tube 74. One end of the fixed tube 74 is closed, and the other end is connected with the shielding container 4. Liquid is injected into the filling hole 7301, and the liquid flows into the fixed tube 74 along the filling hole 7301 and flows into the shielding container 4 along the fixed tube 74 until the shielding container 4 is filled with liquid. In this way, the gas in the shielding container 4 can be discharged, and the gas between the probe 61 and the soil profile 270 is replaced by liquid. In this way, the attenuation of the sound waves emitted and received by the probe 61 can be reduced. The attenuation of sound waves when propagating in liquid is less than the attenuation of sound waves when propagating in air.

[0032] In some embodiments, see Figures 9 to 12 The lifting shaft 73 is divided along its length direction, 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 provided with threaded holes 7302, and the bottom of the split section 732 has a threaded portion 7303, which 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. After the use of this device is completed, 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 in sequence. 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 .

[0033] In some embodiments, see Figure 1 , Figure 5 and Fig.10 , the connection unit also includes a filling funnel 75. The bottom of the filling funnel 75 is inserted into the uppermost threaded hole 7302 and is provided with an exposed thread connected to the threaded hole 7302. The outer diameter of the upper part 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, once a fault occurs and causes the lifting shaft 73 to slide freely, such as the rope of the winch breaks, the upper part of the filling funnel 75 can be 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.

[0034] 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.

[0035] In this embodiment, the cable in the sonic logging tool can pass through the sliding tube 8.

[0036] 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, and 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.

[0037] In this embodiment, the third driving assembly 9 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0038] Furthermore, the top wall of the shielding container 4 is provided with a groove, and the third drive assembly 9 is inserted into the groove, so as to protect the third drive assembly 9 to a certain extent. The volume in the shielding container 4 can be reduced by the groove, so that the shielding container 4 is more easily filled with liquid. In this embodiment, two groups of grooves and third drive assemblies 9 can be provided. In addition, an intermediate piece 260 can be fixedly mounted outside the sliding tube 8, and the intermediate piece 260 is fixedly connected to the two second telescopic rods, thereby indirectly realizing the fixed connection between the two second piston rods and the sliding tube 8.

[0039] In some embodiments, see Figure 1 , Figure 6 and Fig.13The soil profile acoustic wave survey device also includes a positioning rod 10, a fixing member 110 and a fourth driving 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 driving 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 rod 10 can penetrate into the underground or be pulled out from the underground. When the fourth driving assembly 120 drives the fixing member 110 to descend, so that the lower ends of the multiple positioning rods 10 penetrate into the underground, the movement of the device can be restricted. In this way, when the opening 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, and the risk of the device falling from the soil profile 270 is avoided.

[0040] 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.

[0041] 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.

[0042] In this embodiment, the fourth driving assembly 120 may be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0043] In some embodiments, see Figure 1 , Figure 4 , Figure 6 and Fig.13, a receiving groove 1101 is provided on the top surface of the fixing member 110, and the soil profile acoustic wave survey device also includes a supporting frame 1501, a filter screen 1502, a liquid inlet pipe 160, a liquid pump 170 and a liquid outlet pipe 180. The supporting frame 1501 is located in the receiving groove 1101, and the supporting frame 1501 is horizontally arranged and circumferentially fitted and fixed to the inner side surface of the receiving groove 1101. The filter screen 1502 covers the supporting frame 1501 and is fitted and fixed to the supporting frame 1501, so that the receiving groove 1101 has a storage space 11011 located 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 arranged on the fixing member 110, and the inlet of the liquid pump 170 is 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. The storage space 11011 is used to store liquid. The liquid pump 170 can extract the liquid in the storage space 11011 through the liquid inlet pipe 160, and then discharge it through the liquid outlet pipe 180, and inject the liquid discharged from the liquid outlet pipe 180 into the filling hole 7301. The filter net 1502 can prevent impurities from entering the storage space 11011. After the device is used, the disassembled split section 732 can be placed on the filter net 1502 in the receiving tank 1101, and the support frame 1501 supports the split section 732 through the filter net 1502.

[0044] 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 is a U-shaped structure, and the filling tube 190 has a first section 1901 and a second section 1902 which are parallel to each other. The two ends of the filling hose 200 are respectively connected to the free end of the liquid outlet pipe 180 and the end of the filling tube 190 located on the second section 1902. The elastic plug 210 is sleeved and fixed outside the first section 1901, and the elastic plug 210 is used to be 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. The operator can hold the second section 1902, and then insert the elastic plug 210 into one of the filling funnels 75, and use the elastic deformation of the elastic plug 210 to squeeze the filling funnel 75, thereby preventing the elastic plug 210 from withdrawing from the filling funnel 75, and then the operator can 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 .

[0045] 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 .

[0046] In some embodiments, see Figure 1 , Figure 6 and Fig.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 arranged 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 in the vehicle body 1. Among them, the lifting and lowering of the fixing member 110 can make the fixing member 110 slide into or out of the limit frame 230. When the multiple split segments 732 are placed on the filter screen 1502 in the receiving 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 device is used, the fourth drive component 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 taken away. 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 take out the split section 732 from the receiving groove 1101.

[0047] 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 protection scope of the present invention.
