Abstract
Description
Technical Field
[0001] This utility model relates to the field of probe structure technology, and in particular to the probe structure of a seepage borehole acoustic wave testing device. Background Technology
[0002] Currently, borehole exploration is frequently used in engineering geological surveys. The workload of borehole acoustic testing is very large. When conducting acoustic testing in the borehole, the probe is fully coupled with water to the borehole wall. If there are cracks or fracture zones in the borehole, it is difficult to retain water in the borehole after water injection, which makes it impossible to complete the borehole acoustic testing.
[0003] In existing technologies, the common practice is to place the acoustic probe inside a water-filled capsule. Water is injected into the capsule, and once it is full, the probe is fully coupled with the borehole wall, allowing for testing. After the test, the air inside the capsule is released, and the water flows out naturally by gravity, moving the probe to the next test point. Because the borehole needs to be frequently filled and drained, the testing time is relatively long. Therefore, it is necessary to improve the probe structure of the seepage borehole acoustic testing equipment to solve the above problems. Utility Model Content
[0004] To overcome the problem that existing commercially available acoustic probes are generally placed inside water-filled capsules, and water needs to be injected into the capsules frequently, which leads to long testing times and reduces the practicality of the probes.
[0005] The technical solution of this utility model is as follows: a probe structure for a seepage borehole acoustic wave testing device, including a broken hole, a plug, and a stabilizing component. The plug is installed inside the broken hole, and the acoustic wave probe body is fixedly connected to the bottom of the plug. An expansion tube is fixedly connected to the outside of the plug. A stabilizing component to improve the stability of the acoustic wave probe body is installed outside the plug. A connector is fixedly connected to the top of the plug. The acoustic wave tester body is installed at the top right end of the broken hole. An air intake and exhaust pump is installed at the top right end of the broken hole. A high-pressure pipe is installed between the air intake and exhaust pump and the expansion tube. The high-pressure pipe is fixedly installed inside the connector and fixedly connected inside the plug. A cable is fixedly connected between the acoustic wave tester body and the acoustic wave probe body. The cable is installed inside the connector and fixedly connected inside the plug.
[0006] Preferably, the connector has a matching groove at the corresponding position of the high-pressure pipe, and the high-pressure pipe is placed in the groove of the connector.
[0007] Preferably, the connector has a matching groove at the corresponding position of the cable, and the cable is placed in the groove of the connector.
[0008] Preferably, the cable has internal graduations.
[0009] Preferably, the stabilizing component includes a fixed frame, which is fixedly connected to the outside of the occluder. A sliding disk is slidably connected inside the fixed frame. A spring is fixedly connected between the sliding disk and the fixed frame. A sliding sleeve is fixedly connected to the outside of the sliding disk. The sliding sleeve is slidably connected inside the fixed frame. A steel ball is rolled inside the sliding sleeve.
[0010] Preferably, there are twenty sets of sliding discs, spring sliding sleeves and steel balls, which are symmetrically distributed from top to bottom inside the plugger.
[0011] Preferably, the fixed frame has a matching groove at the corresponding position of the sliding disk, and the sliding disk slides within the groove of the fixed frame.
[0012] The beneficial effects of this utility model are as follows: Compared with the existing commercially available methods that place the acoustic probe inside a water-filled capsule, inflate the expansion tube to make it fit tightly against the inner wall of the broken hole, avoid or reduce seepage, and then inject water into the broken hole, the acoustic testing conditions can be met by injecting a certain amount of water. The acoustic testing instrument can then be used to test the broken hole test area to achieve better exploration. This invention simplifies the operation steps, reduces testing time, and improves the practicality of the device. It avoids the problem of frequent water injection and drainage in the hole, which leads to long testing times and reduces the practicality of the probe. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a probe structure for a seepage borehole acoustic testing device, including a broken hole 1, a plug 21, and a stabilizing component. The plug 21 is disposed inside the broken hole 1. An acoustic probe body 22 is fixedly connected to the bottom of the plug 21. An expansion tube 27 is fixedly connected to the outside of the plug 21. A stabilizing component to improve the stability of the acoustic probe body 22 is disposed outside the plug 21. A connector 23 is fixedly connected to the top of the plug 21. An acoustic testing instrument body 24 is disposed at the top right end of the broken hole 1. An air intake / exhaust pump 26 is disposed at the top right end of the broken hole 1. The air intake / exhaust pump 26 and... A high-pressure pipe 28 is installed between the expansion tube and the rubber sleeve 27. The high-pressure pipe 28 is fixedly installed inside the connector 23 and fixedly connected to the inside of the plugger 21. A cable 25 is fixedly connected between the acoustic wave tester body 24 and the acoustic wave probe body 22. The cable 25 is installed inside the connector 23 and fixedly connected to the inside of the plugger 21. By inflating the expansion tube and rubber sleeve 27, it is made to fit tightly against the inner wall of the rupture hole 1, thus avoiding or reducing the seepage flow. Then, water is injected into the rupture hole 1. By injecting a certain amount of water, the acoustic wave test conditions can be met. The acoustic wave tester body 24 can then be used to test the rupture hole. The test site 1 of the broken hole is tested to achieve better exploration results, simplify the operation steps, and reduce the testing time. The stabilizing component, by using the acoustic probe body 22 to move the expansion tube sleeve 27 to the test position in the broken hole 1, causes twenty sets of steel balls 35 to roll synchronously downwards against the inner wall of the broken hole 1, propelling the acoustic probe body 22 downwards. The spring 33, based on its elasticity, drives the steel balls 35 to contact the inner wall of the broken hole 1 via the sliding sleeve 34, improving the stability of the acoustic probe body 22's movement. The connector 23 has a corresponding groove at the corresponding position of the high-pressure pipe 28. The high-pressure pipe 28 is installed in the groove of the connector 23, so that the high-pressure pipe 28 is fixed through the connector 23, which facilitates the testing of the broken hole 1 and improves the stability of the test. The connector 23 has a matching groove at the corresponding position of the cable 25, and the cable 25 is installed in the groove of the connector 23, so that the cable 25 is fixed through the connector 23, which facilitates the testing of the broken hole 1 and improves the stability of the test. The cable 25 has a scale 29 inside, which allows the position of the acoustic probe body 22 to be determined, thereby improving the practicality of the device and the testing accuracy of the acoustic probe body 22.
[0021] Please see Figure 4 , Figure 5In this embodiment, the stabilizing component includes a fixed frame 31, which is fixedly connected to the outside of the plugger 21. A sliding disk 32 is slidably connected inside the fixed frame 31. A spring 33 is fixedly connected between the sliding disk 32 and the fixed frame 31. A sliding sleeve 34 is fixedly connected to the outside of the sliding disk 32 and slidably connected inside the fixed frame 31. Steel balls 35 are rolled inside the sliding sleeve 34. During the process of moving the expansion tube rubber sleeve 27 to the test position in the fracture hole 1 using the acoustic probe body 22, the stabilizing component causes twenty sets of steel balls 35 to roll synchronously downwards against the inner wall of the fracture hole 1, causing the acoustic probe body 22 to move downwards. The spring 33, based on its elasticity, causes the steel balls 35 to contact the inner wall of the fracture hole 1 via the sliding sleeve 34, thus improving the stability of the acoustic probe. The moving stability of the body 22 is improved by providing twenty sets of sliding discs 32, springs 33, sliding sleeves 34, and steel balls 35. These twenty sets of sliding discs 32, springs 33, sliding sleeves 34, and steel balls 35 are symmetrically distributed from top to bottom inside the blocker 21. The springs 33, based on their elasticity, drive the steel balls 35 through the sliding sleeves 34 to contact the inner wall of the rupture hole 1, thus improving the moving stability of the acoustic probe body 22 and enhancing its protective effect. The fixed frame 31 has corresponding grooves on the sliding discs 32. The sliding discs 32 slide within the grooves of the fixed frame 31, limiting the sliding sleeves 34 and improving the rolling stability of the steel balls 35. This further enhances the moving stability of the acoustic probe body 22 and improves its protective effect.
[0022] During operation, as the expansion tube sleeve 27 is moved to the test position in the fracture hole 1 using the acoustic probe body 22, twenty sets of steel balls 35 roll synchronously downward against the inner wall of the fracture hole 1, causing the acoustic probe body 22 to move downward. The spring 33, based on its elasticity, drives the steel balls 35 to contact the inner wall of the fracture hole 1 through the sliding sleeve 34, improving the stability of the acoustic probe body 22 and ensuring its safe descent inside the fracture hole 1. Subsequently, by starting the air intake and exhaust pump 26, air is injected into the expansion tube sleeve 27 through the high-pressure pipe 28, making it adhere tightly to the inner wall of the fracture hole 1 to avoid or reduce leakage. Then, water is injected into the fracture hole 1. By injecting a certain amount of water, the acoustic testing conditions are met. The acoustic testing instrument body 24 can then be used to test the test area of the fracture hole 1 to achieve better exploration results.
[0023] Through the above steps, by inflating the expansion tube 27 with air to make it fit tightly against the inner wall of the broken hole 1, leakage is avoided or reduced. Then, water is injected into the broken hole 1. By injecting a certain amount of water, the conditions for acoustic testing can be met. The acoustic testing instrument body 24 can then be used to test the test area of the broken hole 1 to achieve better exploration. This simplifies the operation and solves the problem of frequent water injection and drainage in the hole, which leads to long testing times and reduces the practicality of the probe.
