Description

Technical Field

[0001] This invention belongs to the field of tunnel experimental simulation technology, specifically a water and gas two-phase seepage device for high-temperature fractured rock tunnels. Background Technology

[0002] A tunnel is a type of underground engineering project, primarily used for constructing subways or tunnels for vehicles to pass through. The exterior of a tunnel is generally composed of rock and soil, and the natural chemical substances within it are relatively active. After long-term use, cracks may appear around the tunnel, at which point harmful substances in the soil layer may seep out, affecting vehicles and pedestrians inside the tunnel.

[0003] Sulfur is a common element in rocks and soil layers, and it is widely distributed, usually existing in the form of hydrogen sulfide. Hydrogen sulfide is an acutely toxic gas; inhaling even a small amount of high-concentration hydrogen sulfide can be fatal in a short time. Compared to coal-bearing strata, there is less research on the hazards of hydrogen sulfide in tunnels in non-coal strata. Such studies generally use models for simulation, usually sealing the tunnel and then injecting hydrogen sulfide and water into it, while continuously moving the tunnel face to record the two-phase seepage patterns of hydrogen sulfide gas and water at different excavation distances. However, the water-gas injection system in the model is relatively simple, using a direct injection method. In existing technologies, hydrogen sulfide and water are usually injected into the tunnel together, but it is generally difficult to control the pressure of hydrogen sulfide discharge, i.e., the injection volume of hydrogen sulfide. Therefore, we provide a two-phase seepage device for water and gas in high-temperature fractured rock tunnels. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a water and gas two-phase seepage device for high-temperature fractured rock tunnels, which solves the problem that the existing technology has difficulty in controlling the injection of hydrogen sulfide and water flow, thus leading to inaccurate experimental results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water and gas two-phase seepage device for high-temperature fractured rock tunnels, including a driving component and an adapter component, wherein the adapter component is fixedly mounted on the top of the driving component;

[0010] The diversion assembly includes a mixing tank fixed to the top of the base, and the outside of the mixing tank has a slot.

[0011] The engagement assembly includes a driver that is threaded onto the outer surface of a reciprocating threaded rod. Two constant sliders are fixed on both sides of the driver. The constant sliders are connected to a directional slider via a spring telescopic rod.

[0012] The circulation component includes a storage tank snapped onto the top of the base. A corrugated pipe runs through the storage tank via a connecting pipe one. A solenoid valve is fixedly installed in the middle of the connecting pipe one. The connecting pipe one is fixedly connected to the inside of the corrugated pipe via a reinforcing plate. The corrugated pipe is connected to the inside of the mixing tank via a connecting pipe two. An interlocking plate is fixedly installed on the outside of the corrugated pipe.

[0013] The adapter component includes a leveling device fixed to the side of the square box. A trapezoidal plate slides horizontally inside the leveling device. A limiting plate is engaged with the outer side of the trapezoidal plate. A positioning plate is hinged to the top of the limiting plate. The positioning plate is connected to the limiting plate by a spring. Both sides of the trapezoidal plate are inclined.

[0014] Preferably, the flow assembly further includes a one-way valve fixed inside the connecting pipe 2. When the solenoid valve is open, water or hydrogen sulfide inside the storage tank enters the interior of the bellows through the connecting pipe 1. The motor drives the engagement assembly to move through the reciprocating threaded rod. The directional slider has the same shape as one side of the engagement plate. The directional slider squeezes the interior of the bellows through the engagement plate. When the one-way valve is open, water or hydrogen sulfide inside the bellows enters the interior of the mixing tank through the connecting pipe 2 and is discharged through the slot on the outside of the mixing tank.

[0015] Preferably, the deflecting slider moves and contacts the inclined surface of the trapezoidal plate, the deflecting slider rises and intersects with the outer side of the biting plate, the deflecting slider no longer drives the biting plate to squeeze the inside of the bellows, and a fixing block is fixedly installed at one end of the top of the limiting plate located outside the positioning plate. The fixing block is used to limit the movement angle of the positioning plate, and the positioning plate is used to limit the reverse movement of the biting plate.

[0016] Preferably, the drive assembly further includes a blade wheel fixed to the other side of the motor output shaft, the blade wheel being located inside the mixing tank.

[0017] Preferably, the adapter component further includes a positioning block slidably installed on the outside of the trapezoidal plate, and the outside of the leveler is provided with a plurality of grooves. The positioning block is adapted to the grooves. The trapezoidal plate is connected to the limiting plate through a spring telescopic rod. A pressure block is fixedly installed on the top of the limiting plate.

[0018] Preferably, the top of the spring telescopic rod is connected to a constant slider, and its bottom is connected to a reversing slider. The elastic force of the engagement assembly drives the reversing slider to always move at the top of the leveler.

[0019] Preferably, the diversion assembly further includes a trigger rotatably mounted on the outside of the mixing tank. The trigger has two cover plates at its upper and lower ends. A sealing tube is fixedly installed on the outside of the mixing tank. The trigger moves within a groove on the outer surface of the sealing tube and is used to seal the groove on the outside of the mixing tank.

[0020] Preferably, the outer sides of the trigger and the driver are both inclined and adapted to each other.

[0021] Preferably, a limiting block is fixedly installed on the outside of the mixing tank, and the outside of the mixing tank is hinged to the trigger via an arc-shaped spring telescopic rod.

[0022] Preferably, the inner wall of the sealing tube is provided with a threaded groove, and the sealing tube is used to connect the experimental model.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention utilizes the coordinated structure of a drive component and an adapter component. A motor drives the engagement component to move, while a deflector slider moves via a leveling device and contacts a trapezoidal plate. The deflector slider then moves upwards and gradually intersects with one side of the engagement plate. During this process, the deflector slider causes the engagement plate to pass over the positioning plate. When the deflector slider is completely disengaged from the engagement plate, the engagement plate no longer contacts it. By setting two adapter components at different positions, the concentration and pressure of injected hydrogen sulfide can be controlled, thereby simulating the seepage patterns of hydrogen sulfide and water under different conditions.

[0025] This invention, through the coordinated arrangement of components such as a flow divider and a drive assembly, allows water and hydrogen sulfide to enter the mixing tank together. The paddle wheel then strikes the water flow, condensing it into droplets. At this point, the water and gas mix inside the mixing tank. Because the flow divider is sealed, pressure is created inside the device after compression. When the engagement assembly moves to its end, the driver pushes the trigger to tilt, thus no longer obstructing the slot on one side of the mixing tank. The pressure inside the device allows the water-gas mixture to be smoothly discharged through the sealed pipe and external pipeline, thereby increasing the contact area between hydrogen sulfide and water and making the simulated environment more realistic.

[0026] This invention, through the coordinated arrangement of drive components and flow components, enables hydrogen sulfide and water to be mixed and injected in small, multiple batches via a reciprocating threaded rod. This improves the efficiency and effectiveness of water-gas mixing while avoiding the possibility of explosion due to excessive pressure between hydrogen sulfide and water, thus enhancing the safety of the device.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 10 As shown, the present invention provides a water and gas two-phase seepage device for high-temperature fractured rock mass tunnels, including a drive assembly 100 and an adapter assembly 200, the adapter assembly 200 being fixedly mounted on the top of the drive assembly 100.

[0040] There are two flow components 300, which are respectively disposed at both ends of the top of the drive component 100;

[0041] Diverter assembly 400 is used to mix and release a mixture of hydrogen sulfide and water;

[0042] The drive assembly 100 includes a base 101, a square box 102 and a motor 103 are fixedly mounted on the top of the base 101, a reciprocating threaded rod 105 is fixedly mounted on one side of the output shaft of the motor 103, the reciprocating threaded rod 105 is rotatably mounted inside the square box 102, and a meshing assembly 106 is threadedly sleeved on the outer surface of the reciprocating threaded rod 105.

[0043] The diversion assembly 400 includes a mixing tank 401 fixedly mounted on the top of the base 101, and the outside of the mixing tank 401 is provided with a slot.

[0044] The engagement assembly 106 includes a driver 1061 threaded onto the outer surface of a reciprocating threaded rod 105. Two constant sliders 1062 are fixedly mounted on both sides of the driver 1061. The constant sliders 1062 are connected to a reversing slider 1063 via a spring telescopic rod 1064.

[0045] The circulation component 300 includes a storage tank 301 snapped onto the top of the base 101. The storage tank 301 is connected to a bellows 304 through a connecting pipe 302. A solenoid valve 303 is fixedly installed in the middle of the connecting pipe 302. The connecting pipe 302 is fixedly connected to the inside of the bellows 304 through a reinforcing plate 307. The bellows 304 is connected to the inside of the mixing tank 401 through a connecting pipe 305. An interlocking plate 308 is fixedly installed on the outside of the bellows 304.

[0046] The adapter component 200 includes a leveling device 201 fixed to the side of the square box 102. A trapezoidal plate 202 slides horizontally inside the leveling device 201. A limiting plate 204 is engaged on the outer side of the trapezoidal plate 202. A positioning plate 206 is hinged to the top of the limiting plate 204. The positioning plate 206 is connected to the limiting plate 204 by a spring 207. Both sides of the trapezoidal plate 202 are inclined.

[0047] The above scheme allows for the control of the length of the corrugated pipe 304 by setting two adapter components 200 at different positions. This, in turn, controls the concentration and pressure of injected hydrogen sulfide, thus simulating the seepage patterns of hydrogen sulfide and water under different conditions. It is worth noting that both storage tanks 301 are snapped into the top of the base 101, and their ports are snapped into the connecting pipe 302. When the hydrogen sulfide or water inside is used up, it can be directly removed and replaced, further improving the convenience of the device.

[0048] like Figure 6 , Figure 7 As shown, the flow assembly 300 also includes a one-way valve 306 fixed inside the connecting pipe 2 305. When the solenoid valve 303 is opened, water or hydrogen sulfide inside the storage tank 301 enters the interior of the bellows 304 through the connecting pipe 1 302. The motor 103 drives the engagement assembly 106 to move through the reciprocating threaded rod 105. The reversing slider 1063 has the same shape as one side of the engagement plate 308. The reversing slider 1063 squeezes the interior of the bellows 304 through the engagement plate 308. The one-way valve 306 opens, and the water or hydrogen sulfide inside the bellows 304 enters the interior of the mixing tank 401 through the connecting pipe 2 305 and is discharged through the slot on the outside of the mixing tank 401.

[0049] Using the above scheme: water and hydrogen sulfide first enter the bellows 304. At this time, the amount of air entering the bellows 304 can be precisely controlled. Whenever the engagement component 106 drives the bellows 304 to move in the opposite direction, the solenoid valve 303 can be opened immediately according to computer control, allowing water and hydrogen sulfide in the storage tank 301 to enter the bellows 304, further improving the working efficiency of the device.

[0050] like Figure 6 , Figure 7 , Figure 10 As shown, the deflecting slider 1063 moves and contacts the inclined surface of the trapezoidal plate 202. The deflecting slider 1063 rises and intersects with the outer side of the biting plate 308. The deflecting slider 1063 no longer drives the biting plate 308 to squeeze the inside of the bellows 304. A fixing block is fixed at one end of the top of the limiting plate 204 located outside the positioning plate 206. The fixing block is used to limit the movement angle of the positioning plate 206. The positioning plate 206 is used to limit the reverse movement of the biting plate 308. The top of the spring telescopic rod 1064 is connected to the constant slider 1062, and its bottom is connected to the deflecting slider 1063. The elastic force of the biting assembly 106 drives the deflecting slider 1063 to always move at the top of the leveler 201.

[0051] The above scheme is adopted: During the process of the reversing slider 1063 passing through the inclined surface of the trapezoidal plate 202, the reversing slider 1063 can still drive the biting plate 308 to move and press it against the positioning plate 206, causing it to fold. After the biting plate 308 passes the positioning plate 206, the reversing slider 1063 is located at the top of the trapezoidal plate 202 and is interlaced with the biting plate 308. At this time, the biting plate 308 is no longer pushed by it, and the water flow or hydrogen sulfide inside the bellows 304 no longer enters the interior of the mixing tank 401. The fixed block restricts the positioning plate 206 to always be in a vertical state. At this time, the biting plate 308 cannot move in the opposite direction, which further improves the stability of the device.

[0052] like Figure 4 As shown, the drive assembly 100 also includes a blade wheel 104 fixed to the other side of the output shaft of the motor 103, and the blade wheel 104 is located inside the mixing tank 401.

[0053] Using the above scheme: when water and hydrogen sulfide are inside the mixing tank 401, the paddle wheel 104 can disperse the water flow into water droplets, so that the water and hydrogen sulfide can be fully mixed.

[0054] like Figures 6-9As shown, the adapter component 200 also includes a positioning block 203 that is slidably installed on the outside of the trapezoidal plate 202. The flattener 201 has several grooves on its outside. The positioning block 203 is adapted to the grooves. The trapezoidal plate 202 is connected to the limiting plate 204 through a spring telescopic rod 205. A pressure block is fixed on the top of the limiting plate 204.

[0055] The above solution is adopted: such as Figure 8 When the engagement component 106 moves in the opposite direction, the trapezoidal plate 202 shown in the diagram will inevitably pass through it. Its movement trajectory should be: rising-falling. When it falls, the deflecting slider 1063 should engage with the engagement plate 308, and the deflecting slider 1063 can press the pressure block and cause the limiting plate 204 to fall. At this time, the positioning plate 206 can no longer restrict the position of the engagement plate 308, and the engagement component 106 can drive the bellows 304 to move in the opposite direction. At this time, the solenoid valve 303 is in the open state and the one-way valve 306 is in the closed state, further improving its smooth operation.

[0056] like Figures 1-4 As shown, the diversion assembly 400 also includes a trigger 402 rotatably mounted on the outside of the mixing tank 401. Two cover plates 405 are provided at the upper and lower ends of the trigger 402. A sealing tube 403 is fixedly installed on the outside of the mixing tank 401. The trigger 402 moves within a groove on the outer surface of the sealing tube 403, and is used to seal the groove on the outside of the mixing tank 401. The trigger 402 and the outer side of the driver 1061 are both inclined and compatible. A limiting block 406 is fixedly installed on the outside of the mixing tank 401, and the outside of the mixing tank 401 is hinged to the trigger 402 via an arc-shaped spring telescopic rod 404. A threaded groove is formed on the inner wall of the sealing tube 403, which is used for docking with the experimental model.

[0057] Using the above scheme: Motor 103 drives the engagement assembly 106 to reciprocate through reciprocating threaded rod 105. The engagement assembly 106 immediately squeezes the inside of the two bellows 304 through the two engagement plates 308. At this time, the solenoid valve 303 is closed, that is, the storage tank 301 no longer supplies air and hydrogen sulfide into the bellows 304. At this time, both enter the mixing tank 401 together. At the same time, the paddle wheel 104 will strike the hydrogen sulfide, making it into water droplets, and it will fully mix with the air. At this time, water and air are mixed inside the mixing tank 401. When the engagement assembly 106 moves to the end, one side of the driver 1061 contacts one side of the trigger 402. Since both are in a vertical state and the sides are tilted... When the device is tilted, the driver 1061 pushes the trigger 402 to tilt, thus no longer blocking the injection port on one side of the mixing tank 401. At this time, the pressure in the device can smoothly discharge the water-gas mixture through the sealing pipe 403 and the external pipe. The remaining small amount of hydrogen sulfide will be blown out by the paddle wheel 104. The edge of the trigger 402 is arc-shaped. Due to the large air pressure inside, the water-gas mixture can be discharged quickly. After the injection is completed, the pulling force of the arc-shaped spring telescopic rod 404 can make the trigger 402 reseal the slot on the outside of the mixing tank 401, so that the next injection can be carried out. The above structure enables the device to quickly inject the water-gas mixture and apply a certain degree of pressure to it, thereby increasing its working effect.

[0058] Working principle and usage process of this invention:

[0059] First, the sealing pipe 403 is connected to the tunnel model via a dedicated experimental pipeline. Then, it's necessary to ensure that the two storage tanks 301 contain water and hydrogen sulfide, respectively. At this point, the amount of air or hydrogen sulfide discharged from the bellows 304 can be controlled by the adapter component 200. When the device is activated, the motor 103 drives the engagement component 106 in a reciprocating motion via the reciprocating threaded rod 105. The engagement component 106 immediately compresses the interior of the two bellows 304 through the two engagement plates 308. At this time, the solenoid valve 303 closes, meaning that the storage tank 301 no longer supplies air and hydrogen sulfide into the bellows 304. Both then enter the mixing tank 401 together. As it enters the interior, the blade wheel 104 strikes the hydrogen sulfide, turning it into water droplets, and mixes it thoroughly with the air. At this time, the water and gas are mixed inside the mixing tank 401. When the engagement assembly 106 moves to the end, one side of the driver 1061 contacts one side of the trigger 402. Since both are in a vertical position and the sides are tilted, the driver 1061 pushes the trigger 402 to tilt, thus no longer blocking the injection hole on one side of the mixing tank 401. At this time, the pressure in the device can smoothly discharge the water and gas mixture through the sealing pipe 403 and the external pipe. The remaining small amount of hydrogen sulfide will be blown out by the blade wheel 104.

[0060] It is important to note that when the deflector slider 1063 moves through the leveling device 201 and contacts the trapezoidal plate 202, its inclined side design causes it to move upwards and gradually intersect with one side of the engagement plate 308. During this process, the deflector slider 1063 drives the engagement plate 308 past the positioning plate 206. When the deflector slider 1063 is completely disengaged from the engagement plate 308, the engagement plate 308 no longer contacts it, and its interior is no longer compressed. The positioning plate 206 then prevents the engagement plate 308 from moving back. By setting the two adapter components 200 at different positions, the concentration and pressure of hydrogen sulfide injection can be controlled to simulate the pattern of hydrogen sulfide and water seepage under different conditions.
