Abstract
Description
Technical Field
[0001] This application relates to the field of mine auxiliary equipment technology, and more specifically, to an air-filling device and a borehole detector assembly. Background Technology
[0002] Currently, in mine seismic exploration, in-hole geophones play a crucial role in data collection. These geophones are placed through detector holes in the coal face. If the diameter of the detector hole is slightly larger than the diameter of the geophone, the geophone cannot make proper contact with the coal face after being placed inside. To ensure proper coupling between the geophone and the coal face, it is usually inflated with air to achieve a close fit, thus guaranteeing the stability and high quality of signal reception.
[0003] The current inflation process involves directly inflating the air bladder in the borehole detector using an air pump, causing the detector to bulge and adhere to the coal wall. However, this inflation method has poor sealing, leading to gas leakage over time and reduced contact between the detector and the coal wall. Furthermore, directly inflating the detector with an air pump introduces significant human interference, and the external inflation port of the detector is exposed to the outside environment, making it susceptible to damage.
[0004] Therefore, an inflation device and an in-hole detector assembly are needed to solve the above problems. Utility Model Content
[0005] In view of this, the purpose of this application is to provide an inflation device and an in-hole detector assembly to solve the problem of unsatisfactory inflation effect of existing in-hole detectors.

[0007] Inflatable mechanism;
[0008] A barrier pipe includes a pipe body and a barrier structure disposed within the pipe body. The two opposite ends of the pipe body are an air inlet and an air outlet, respectively. The air inlet is connected to an inflation mechanism, which supplies air to the pipe body through the air inlet. The air outlet is connected to a component to be inflated. The barrier structure can control the opening and closing of the pipe body.

[0011] Optionally, the movable inflation tube is threadedly connected to the fixed inflation tube.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0034] Figure 1 This is a schematic diagram of the inflation device used in a specific embodiment of this application. Figure 2 for Figure 1 The diagram shows the open state of the gas barrier sphere. Figure 3 for Figure 1 The diagram shows the closed state of the gas barrier sphere. Figures 1 to 3 As shown, the inflation device includes an inflation mechanism 7 and a barrier pipe.
[0035] The inflation mechanism 7 includes, but is not limited to, an air pump; the barrier pipe includes a pipe body 4 and a barrier structure installed inside the pipe body 4. The two opposite ends of the pipe body 4 are an air inlet and an air outlet, respectively. The air inlet is connected to the inflation mechanism 7, and the inflation mechanism 7 supplies air to the pipe body 4 through the air inlet; the air outlet is connected to the component to be inflated; the barrier structure can control the opening and closing of the pipe body 4.
[0036] The inflation mechanism 7 is connected to the air inlet end of the pipe body 4. The barrier structure is installed inside the pipe body 4 and located between the air inlet end and the air outlet end. The air outlet 42 of the air outlet end of the pipe body 4 is connected to the component to be inflated. When the barrier structure is in the first state, the air inlet end and the air outlet end of the pipe body 4 are not connected to each other, and the gas at the air inlet end cannot reach the air outlet end through the barrier channel. When the barrier structure is in the second state, the air inlet end and the air outlet end of the pipe body 4 are connected, and the gas at the air inlet end reaches the air outlet end through the barrier channel.
[0037] When in use, the barrier structure is in the first state. A small amount of gas is injected into the air inlet end of the pipe body 4 through the inflation mechanism 7. Due to the barrier effect of the barrier structure, the gas forms a large pressure on the air inlet side, and the gas in the pipe body 4 can no longer be injected. This indicates that the airtightness of the inflation device is good. Otherwise, the airtightness of the inflation device needs to be checked.
[0038] Subsequently, the barrier structure switches from the first state to the second state, and the gas enters the part to be inflated from the inflation mechanism 7 through the inlet end, the main body of the pipe 4, the barrier structure, and the outlet end. After inflation is completed, the barrier structure switches from the second state to the first state.
[0039] Taking the in-hole detector 1 as an example, the in-hole detector 1 is connected to the outlet end of the barrier pipe via the detector inflation line 12. When the barrier structure is in its first state, a small amount of gas is injected into the inlet end of the pipe body 4 via the inflation mechanism 7. Due to the barrier effect, the gas forms a large pressure on the inlet side, preventing further gas injection into the pipe body 4. Subsequently, the barrier structure switches from the first state to the second state, and gas flows from the inflation mechanism 7 through the inlet end, the pipe body 4, the barrier structure, the outlet end, and the detector inflation line 12 into the in-hole detector 1. After inflation is complete, the barrier structure switches from the second state to the first state, separating the inflation mechanism 7 from the barrier pipe. The in-hole detector 1 connected to the barrier pipe can then be placed in the operating environment.
[0040] By using the above-mentioned inflation device and the barrier structure set inside the barrier pipe to control the opening and closing of the main body 4 of the pipe, the airtightness of the detector 1 in the hole can be effectively increased during the inflation process and during use, and gas leakage is prevented, thereby achieving the stability and high quality of signal reception of the detector 1 in the hole.
[0041] To facilitate inflation, the inflation mechanism 7 may optionally include an inflation tube assembly. The inflation mechanism 7 is connected to the inflation tube assembly via an inflation line, and the inflation tube assembly is connected to the air inlet. The two ends of the inflation line are respectively connected to the output end of the inflation mechanism 7 and the inflation tube assembly, and the inflation tube assembly is connected to the barrier pipe. The inflation mechanism 7 supplies air to the air inlet through the inflation line and the inflation tube assembly, and the air enters the pipe body 4 through the air inlet.
[0042] Typically, the inflation tube assembly and the air inlet are detachably connected, allowing the inflation mechanism 7 to be detachably connected to the barrier tube for easy use and storage.
[0043] To further facilitate disassembly and use, the inflation tube assembly optionally includes a fixed inflation tube 5 and a movable inflation tube 6. The fixed inflation tube 5 is connected to the air inlet, and the movable inflation tube 6 is connected to the inflation line. The movable inflation tube 6 is detachably connected to the fixed inflation tube 5. Before inflation, the movable inflation tube 6 is connected to the fixed inflation tube 5, and the inflation mechanism 7 can inflate the blocking tube. After inflation, the movable inflation tube 6 is separated from the fixed inflation tube 5.
[0044] To further reduce the difficulty of disassembly and assembly, the movable inflation tube 6 may optionally be threadedly connected to the fixed inflation tube 5. The inner surface of the tube wall 51 of the fixed inflation tube 5 is provided with an internal thread 52, and the outer surface of the movable inflation tube 6 is provided with an external thread 61. The air outlet of the movable inflation tube 6 is located inside the tube wall 51, and the air inlet 62 of the movable inflation tube 6 is connected to the inflation line.
[0045] Optionally, the barrier structure includes a barrier ball and a control component. The barrier ball has a channel inside, and the control component controls the opening and closing of the channel. The barrier ball is disposed within the pipe body 4, and the opening and closing of the channel controls the opening and closing of the pipe body 4. The barrier ball is installed inside the pipe body 4, typically in the middle of the pipe body 4. After moving to a designated position, the barrier ball stops rolling but can rotate relative to the pipe body 4. The barrier ball divides the pipe body 4 into an inlet and an outlet. When the channel within the barrier ball is open, the inlet and outlet can communicate with each other, allowing gas to flow back and forth. When the channel is closed, the inlet and outlet cannot communicate, and gas no longer flows in or out. The opening and closing of the channel is controlled by the control component. For example, when the control component controls the channel and the pipe body 4 to be parallel to each other, the channel is in a connected state; when the control component controls the channel and the pipe body 4 to be perpendicular to each other, the pipe wall of the pipe body 4 can block the opposite ends of the channel, and the channel is in a closed state. Using the above barrier structure, the structure is relatively simple, easy to control, and convenient to operate.
[0046] Optionally, the blocking sphere includes a blocking sphere body 32 and two blocking hemispheres 33 located on opposite sides of the blocking sphere body 32. A channel passes through the blocking sphere body 32 and the two blocking hemispheres 33. A control component is connected to the blocking sphere body 32 and can control the blocking sphere body 32 and the two blocking hemispheres 33 to reciprocate synchronously. A ball hole is provided on each opposite side of the blocking sphere body 32, and the blocking hemispheres 33 are installed in the ball holes, with the blocking hemispheres 33 being rugby ball-shaped. The blocking sphere body 32 and the two blocking hemispheres 33 are assembled together to form a spherical structure. The inner wall 331 of the blocking hemispheres 33 is in contact with the blocking sphere body 32, while the outer wall 333 of the blocking hemispheres 33 is exposed to the external environment. The channel passes through the blocking sphere body 32 and the two blocking hemispheres 33, and the channel typically passes through the center of the blocking sphere. The movement of the blocking sphere body 32 and the two blocking hemispheres 33 is synchronous. When the control unit drives the barrier ball body 32 to rotate, the barrier ball body 32 can drive the two barrier hemispheres 33 to rotate synchronously. By using the two barrier hemispheres 33 and the barrier ball body 32 in cooperation with each other, and in conjunction with the control unit to control the opening and closing of the channel, the opening and closing of the pipeline body 4 can be realized. The barrier ball structure is relatively compact and easy to control.
[0047] Optionally, the channel includes a main channel 31 and a hemispherical channel 332. The main channel 31 passes through the center of the blocking sphere 32 and is configured to pass through it. The hemispherical channel 332 passes through the center of the blocking hemisphere 33 and is configured to pass through it. The two ends of the main channel 31 are respectively connected to the hemispherical channels 332 on both sides. The two ends of the main channel 31 are respectively connected to the close ends of the two hemispherical channels 332 on both sides, and the far ends of the two hemispherical channels 332 are located on the outer wall 333 of the barrier hemisphere 33. The main channel 31 and the two hemispherical channels 332 on both sides are connected to form a straight channel. When the axis of the main channel is parallel to that of the pipe body 4, the pipe wall of the main channel 4 does not obstruct the port of the hemispherical channel 332 on the outer wall 333 of the barrier hemisphere 33, so it is in a connected state. When the axis of the main channel is perpendicular to that of the pipe body 4, the pipe wall of the main channel 4 closes the port of the hemispherical channel 332 on the outer wall 333 of the barrier hemisphere 33, so it is in a cut-off state.
[0048] Optionally, the control component 2 includes a drive rod 21 and a driven rod 22 connected to the drive rod 21. The free end of the driven rod 22 passes through the pipe body 4 and is connected to the barrier ball body 32; the free end of the drive rod 21 is exposed outside the pipe body 4. Typically, the drive rod 21 is a horizontal rod, and the driven rod 22 is a vertical rod. The opposite ends of the vertical rod are connected to the horizontal rod inside and outside the pipe body 4 and the barrier ball body 32, respectively. Rotating the drive rod 21 causes the driven rod 22 to rotate, which in turn causes the gas barrier ball 3 to rotate. Using the above-mentioned control component makes operation easy and reduces control difficulty.
[0049] In addition, this application provides an in-hole detector 1 assembly, including: an in-hole detector 1; and an inflation device as described above, the inflation device being used to supply air to the in-hole detector 1.
[0050] The in-hole detector 1 is connected to the outlet end of the barrier pipe. With the barrier structure in a blocked state, a small amount of gas is introduced into the inlet end of the pipe body 4 via the inflation mechanism 7. Due to the barrier effect, the gas forms a large pressure on the inlet side, preventing further gas from entering the pipe body 4. Subsequently, the barrier structure switches from a blocked state to an open state, allowing gas to flow from the inflation mechanism 7 through the inlet end, pipe body 4, barrier structure, outlet end, and detector inflation line 12 into the in-hole detector 1. After inflation is complete, the barrier structure switches from an open state to a blocked state, separating the inflation mechanism 7 from the barrier pipe. The in-hole detector 1 connected to the barrier pipe can then be placed in its operating environment.
[0051] Optionally, the in-hole detector 1 includes a detector body 11 and a detector inflation line 12. The two ends of the inflation line 12 are connected to the air bladder of the detector body 11 and the air outlet of the inflation device, respectively. One end of the inflation line 12 is connected to the air bladder of the detector body 11, and the other end is connected to the air outlet of the blocking pipe. Gas discharged from the air outlet of the pipe body 4 enters the air bladder of the detector body 11 through the inflation line 12, achieving inflation. Using the above-mentioned in-hole detector 1, the structure is relatively simple and easy to operate. The inflation device ensures the isolation of the air bladder from the outside world, enhances the overall airtightness of the air bladder, and ensures the stability during seismic data acquisition.
[0052] The following section further describes the usage process of the in-hole detector assembly.
[0053] Before inflation, check the airtightness of the detector assembly in the hole, and check the outer walls of the detector 1, the main body of the pipe 4, the fixed inflation pipe 5, the movable inflation pipe 6 and the inflation mechanism 7 in the hole to ensure that there are no obvious cracks; check the integrity and airtightness of the detector inflation line 12 and inflation line 63.
[0054] The detector 1 in the hole is connected to the outlet 42 of the pipe body 4 through the detector inflation line 12. The fixed inflation tube 5 is connected to the inlet end of the pipe body 4. The gas barrier ball 3 is set inside the pipe body 4. The control component 2 (such as an inflation switch) is connected to the pipe body 4 and the gas barrier ball 3. Rotating the inflation switch can control the opening and closing of the gas barrier ball 3.
[0055] The gas-blocking ball 3 comprises a main body 32 and two blocking hemispheres 33. The hemispherical channel 332 is connected to the main channel 31, allowing gas to pass through. The outer wall 333 of the blocking hemispheres contacts the main body 4 of the pipe, blocking the hemispherical channel 332 and preventing gas from passing through. When the inflation switch is rotated to control the line connecting the axes of the two outer walls 333 of the blocking hemispheres to be parallel to the outer wall 41 of the channel, the gas-blocking ball 3 is in the open state, allowing gas to pass through. When the inflation switch is rotated to control the line connecting the axes of the two outer walls 333 of the blocking hemispheres to be perpendicular to the outer wall 41 of the channel, the gas-blocking ball 3 is in the closed state, preventing gas from passing through. In the initial state, the drive rod 21 of the control component 2 is perpendicular to the outer wall 41 of the channel, and the gas-blocking ball 3 is in the closed state, ensuring the isolation of the airbag from the outside world.
[0056] The movable inflation tube 6 is connected to the fixed inflation tube 5 via the external thread 61 and the internal thread 52 of the fixed inflation tube 5. The inflation mechanism 7 is connected to the movable inflation tube 6 via the inflation line 63. A small amount of gas is injected through the inflation mechanism 7. Since the gas blocking ball 3 is in the closed state, the gas is blocked on the inlet side of the pipe body 4, forming a large pressure. This will result in no more gas being injected, indicating that the overall airtightness is good. Otherwise, the airtightness needs to be checked again. Subsequently, the gas blocking ball 3 is opened, that is, the drive rod 21 of the inflation switch rotates to be parallel to the outer wall 41 of the channel, so that the gas enters the detector body 11 from the inflation mechanism 7 through the inflation line 63, the movable inflation tube 6, the fixed inflation tube 5, the pipe body 4, the gas blocking ball 3, and the detector inflation line 12.
[0057] After inflation is complete, first turn the drive lever 21 of the inflation switch until the gas blocking ball 3 is closed. Then separate the fixed inflation tube 5 and the movable inflation tube 6, and place the main body of the pipe 4 in a dry place. The in-hole detector 1 can then be put into use. After the in-hole detector 1 has finished receiving the signal, remove it from the hole and put the blocking pipe and the in-hole detector 1 into the instrument case.
[0058] As can be seen from the above description and practice, the inflation device and in-hole detector assembly provided in this application have the following advantages compared with the prior art: by using the above inflation device, an isolation structure is set inside the isolation pipe to control the opening and closing of the main body of the pipe. During the inflation process and use, the airtightness of the in-hole detector can be effectively increased, and gas leakage is avoided, thereby achieving the stability and high quality of signal reception of the in-hole detector.
[0059] Those skilled in the art should understand that the above description is merely a specific embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the scope of this application should be included within the protection scope of this application.
