Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0034] Example 1: As Figure 1-8 As shown, the present invention provides an acoustic wave testing device for the side arch of an underground cavern, including a testing mechanism 1 and a testing borehole 2. The testing mechanism 1 and the testing borehole 2 are used together. One end of the testing mechanism 1 is provided with a first sealing mechanism 3 that is used in conjunction with the testing borehole 2. The end of the testing mechanism 1 away from the testing borehole 2 is provided with a second sealing mechanism 4. A rotating mechanism 5 is fixedly installed in the middle of the testing mechanism 1. A marking mechanism 6 is fixedly installed in the end of the rotating mechanism 5 away from the testing mechanism 1. A mixing mechanism 7 that is used in conjunction with the testing mechanism 1 is provided in the inner cavity of the marking mechanism 6.

[0035] The testing mechanism 1 includes a test sleeve 11, which can be movably inserted into the test borehole 2. A connecting bushing 12 is fixedly sleeved at one end of the test sleeve 11 near the test borehole 2. An on / off ball valve 13 is fixedly installed on the connecting bushing 12. A cavity is formed inside the test sleeve 11, and the cavity is connected to the on / off ball valve 13 through the connecting bushing 12. A liquid outlet is formed at one end of the test sleeve 11 near the first sealing mechanism 3, allowing liquid introduced by the on / off ball valve 13 and the connecting bushing 12 to be introduced into the test borehole 2 through the cavity and the liquid outlet. This is prior art. Without going into too much detail, a test push rod 14 is slidably inserted into the inner cavity of the test sleeve 11, and a transducer body 15 is fixedly installed at the end of the test push rod 14 near the connecting bushing 12. The transducer body 15 can be movably inserted into the test borehole 2, and a wire body 16 is fixedly connected to the end of the transducer body 15 near the connecting bushing 12. The test push rod 14 has a first mounting cavity 17 and a second mounting cavity 18. The wire body 16 is movably inserted into the first mounting cavity 17, and an exhaust pipe 19 that works with the transducer body 15 is fixedly installed in the second mounting cavity 18.

[0036] By adopting the above technical solution, when in use, the user can push the test push rod 14, which will drive the transducer body 15 to move away from the test sleeve 11. While the transducer body 15 is moving, it will also drive the lead wire body 16 and the exhaust pipe 19 to move. When the end of the transducer body 15 away from the test sleeve 11 contacts the top surface of the test borehole 2, the user can stop pushing the test push rod 14.

[0037] The first sealing mechanism 3 includes a first washer 31 and a rotating sleeve 32. The first washer 31 is fixedly installed at the end of the test sleeve 11 near the transducer body 15, and a first sealing ring 33 is fixedly installed on the side of the first washer 31 away from the transducer body 15. The first sealing ring 33 is movably sleeved on the outside of the test sleeve 11. The rotating sleeve 32 is rotatably sleeved on the outside of the test sleeve 11, and a first internal thread 34 is fixedly installed on the inner wall of the rotating sleeve 32. The end of the test sleeve 11 near the transducer body 15 has an opening. The first threaded groove 110 is provided, and the first internal thread 34 is threadedly connected to the first threaded groove 110. The end of the rotating sleeve 32 near the transducer body 15 is fixedly fitted with a second washer 35. The second washer 35 is movably fitted on the outside of the test sleeve 11, and the side of the second washer 35 near the transducer body 15 is in movable contact with the first sealing ring 33. The end of the rotating sleeve 32 away from the transducer body 15 is fixedly fitted with a rotating ring 36, and the outer wall of the rotating ring 36 is integrally formed with an array of anti-slip protrusions 37.

[0038] By adopting the above technical solution, when in use, the user can rotate the ring 36, which can drive the rotating sleeve 32 to rotate. Then, through the cooperation of the first internal thread 34 and the first thread groove 110, the second washer 35 can be moved to the side closer to the first washer 31, which can further compress the first sealing ring 33, thereby causing the first sealing ring 33 to deform. When the side of the first sealing ring 33 is tightly attached to the outer wall of the test sleeve 11 and the inner wall of the test borehole 2, the rotating ring 36 can be released.

[0039] The second sealing mechanism 4 includes a sealing cylinder 41, which is detachably connected to the test sleeve 11. A first through hole 42 is provided at the end of the sealing cylinder 41 away from the transducer body 15, through which the test push rod 14 can move through the first through hole 42. A second internal thread 43 is fixedly installed on the inner wall of the sealing cylinder 41, and a second thread groove 111 is provided on the outer wall of the end of the test sleeve 11 away from the transducer body 15. The second internal thread 43 can be threadedly connected to the second thread groove 111. A second sealing ring 44 is fixedly installed in the inner cavity of the sealing cylinder 41. The second sealing ring 44 can be movably sleeved on the outside of the test push rod 14, and can movably contact the end of the test sleeve 11 away from the transducer body 15. Anti-slip grooves 45 are provided on the outer wall of the sealing cylinder 41, and the anti-slip grooves 45 are distributed in an array.

[0040] By adopting the above technical solution, when in use, the user can turn the knob to seal the rotating cylinder 41, thereby cooperating with the use of the second internal thread 43 and the second thread groove 111 to drive the second sealing ring 44 to move towards the side closer to the test sleeve 11, until the second sealing ring 44 is squeezed and deformed and tightly fits the test push rod 14 and the test sleeve 11, at which point the sealing rotating cylinder 41 is released.

[0041] The rotating mechanism 5 includes a micro motor 51 and a first convex plate 52. The micro motor 51 is fixedly installed on the outside of the test sleeve 11. A second convex plate 58 is fixedly sleeved on the outer wall of the test sleeve 11, and the micro motor 51 is fixedly inserted into the second convex plate 58. The second convex plate 58 effectively improves the installation stability of the micro motor 51. A first gear 53 is fixedly sleeved at the end of the output end of the micro motor 51. The first convex plate 52 is rotatably sleeved on the outside of the test sleeve 11. A mounting groove 54 is opened on the side of the first convex plate 52 away from the transducer body 15. A drive internal gear ring 55 is fixedly installed in the inner cavity of the mounting groove 54, and the drive internal gear ring 55 meshes with the first gear 53. A second through hole 56 is opened through the first convex plate 52, and an annular rotating plate 57 is fixedly installed on the inner wall of the second through hole 56. A second through hole 56 is opened on the outer wall of the test sleeve 11. An annular groove 112 is provided, the test sleeve 11 is rotatably inserted into the second through hole 56, and the annular rotating plate 57 is rotatably inserted into the annular groove 112. The use of the annular rotating plate 57 and the annular groove 112 ensures the stable rotation of the first convex plate 52. The marking mechanism 6 includes a paint storage tank 61. A third through hole 59 is opened through the end of the first convex plate 52 away from the test sleeve 11, and the paint storage tank 61 is fixedly inserted into the third through hole 59. A paint pump body 62 is fixedly installed at the end of the paint storage tank 61 near the transducer body 15, and a paint guide pipe 63 is fixedly connected to one end of the paint pump body 62. The paint guide pipe 63 is fixedly inserted into the inner cavity of the paint storage tank 61. Multiple paint inlet holes are opened on the paint guide pipe 63 to facilitate the export of paint from the paint storage tank 61. A paint spraying pipe 64 is fixedly installed at the other end of the paint pump body 62.

[0042] By adopting the above technical solution, when abnormal test data occurs, the user can turn on the micro motor 51 and the paint pump body 62. At this time, the micro motor 51 will drive the first gear 53 to rotate, which will drive the internal gear ring 55 to rotate. In turn, the first convex plate 52 will drive the paint storage tank 61 to rotate. At the same time, the paint pump body 62 can guide the paint in the paint storage tank 61 into the paint spraying pipe 64 through the paint guiding pipe 63 and spray the paint onto the outer wall of the abnormal test hole 2. After the paint storage tank 61 is reset, the micro motor 51 and the paint pump body 62 can be turned off. Then, the test operation of the next test hole 2 can be carried out according to the above steps.

[0043] The mixing mechanism 7 includes a mixing rod 71. A fourth through hole 67 is provided at one end of the paint storage tank 61 away from the transducer body 15. The mixing rod 71 is rotatably inserted into the fourth through hole 67, and its lower end extends into the paint storage tank 61. Two mounting rings 72 are fixedly sleeved on the lower part of the mixing rod (71). An array of mixing rotating plates 73 are fixedly connected to the outer wall of the mounting rings 72. A second gear 74 is fixedly sleeved at one end of the mixing rod 71 away from the transducer body 15, and a third gear 75 is fixedly sleeved on the outer side of the test sleeve 11. The second gear 74 and the third gear 75 mesh with each other.

[0044] By adopting the above technical solution, during use, while the paint storage tank 61 rotates, the second gear 74 will roll along the outer wall of the third gear 75, thereby driving the mixing rod 71 to rotate, which in turn drives the mixing plate 73 to rotate through the mounting collar 72, further mixing and stirring the paint, thereby preventing the paint from settling and accumulating, and ensuring the normal operation of the labeling work.

[0045] Example 2: Figure 2 As shown, the end of the paint storage tank 61 near the paint pump body 62 is connected to a paint inlet pipe 65, and a control valve 66 is fixedly installed on the paint inlet pipe 65.

[0046] By adopting the above technical solution, the coordinated action of the paint inlet pipe 65 and the control valve 66 facilitates the paint introduction operation in the paint storage tank 61.

[0047] Working principle: When in use, the user can first turn the control valve 66 to open it, and then the user can introduce an appropriate amount of paint into the paint storage tank 61 through the paint inlet pipe 65. After that, the paint introduction operation can be stopped and the control valve 66 can be closed.

[0048] Subsequently, acoustic testing can be performed on the test borehole 2 of the underground cavern side arch. At this time, the user can insert one end of the transducer body 15 of the acoustic test device for the underground cavern side arch into the test borehole 2 until the first sealing mechanism 3 extends into the test borehole 2. Then, the user can rotate the ring 36, which can drive the rotating sleeve 32 to rotate. Then, through the cooperation of the first internal thread 34 and the first thread groove 110, the second washer 35 can be moved to the side closer to the first washer 31, which can further compress the first sealing ring 33, thereby causing the first sealing ring 33 to deform. When the side of the first sealing ring 33 is tightly attached to the outer wall of the test sleeve 11 and the inner wall of the test borehole 2, the rotating ring 36 can be released.

[0049] The user can then push the test push rod 14, which will move the transducer body 15 away from the test sleeve 11. Simultaneously, the transducer body 15 will move the lead wire body 16 and the exhaust pipe 19. When the end of the transducer body 15 away from the test sleeve 11 contacts the top surface of the test borehole 2, the user can stop pushing the test push rod 14 and turn the sealing cylinder 41. This will, in conjunction with the second internal thread 43 and the second thread groove 111, move the second sealing ring 44 closer to the test sleeve 11 until the second sealing ring 44 is deformed and tightly fitted with the test push rod 14 and the test sleeve 11, at which point it will be released. After sealing the rotating drum 41, the user can connect the water inlet pipe to the opening and closing ball valve 13 and open the opening and closing ball valve 13. At this time, the water pressure can be controlled from small to large. The water flow enters the connecting bushing 12 through the opening and closing ball valve 13, and enters the test borehole 2 through the test sleeve 11. Then it enters the exhaust pipe 19. When water comes out of the exhaust pipe 19, the water pressure is controlled from large to small. Then, the rod and line are retrieved and sampled according to the normal operation. During this period, when it is necessary to retrieve the rod, the knob can be turned in the opposite direction to seal the rotating drum 41 until the sealing rotating drum 41 is reset. The rod can be retrieved after that. After the sampling operation is completed, the opening and closing ball valve 13 can be disconnected from the water inlet pipe and the opening and closing ball valve 13 can be opened to drain the water accumulated in the test borehole 2.

[0050] If the test data for borehole 2 is normal, the user can reverse the rotation of ring 36, thereby resetting the second washer 35 by rotating sleeve 32, and thus restoring the first sealing ring 33. The user can then remove the acoustic wave testing device for the underground cavern's side arch and proceed with the next test borehole 2. If abnormal test data is detected, the user can open the micro motor 51 and paint pump body 62. The micro motor 51 will drive the first gear 53 to rotate, which in turn drives the internal gear ring 55 to rotate, which in turn drives the paint storage tank 61 to rotate via the first convex plate 52. Simultaneously, the paint pump body 62 can rotate through the paint guide pipe. 63. The paint in the paint storage tank 61 is introduced into the paint spraying pipe 64 and sprayed onto the outer wall of the abnormal test hole 2. After the paint storage tank 61 is reset, the micro motor 51 and the paint spraying pump 62 can be turned off. Then, the test operation of the next test hole 2 can be carried out according to the above steps. While the paint storage tank 61 is rotating, the second gear 74 will roll along the outer wall of the third gear 75, thereby driving the mixing rod 71 to rotate. In turn, the mixing plate 73 can be driven to rotate through the mounting collar 72, which can further mix and stir the paint, thereby avoiding the phenomenon of paint sedimentation and accumulation, and thus ensuring the normal operation of the labeling work.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
