Description

Technical Field

[0001] The present invention belongs to the technical field of construction drainage, and more specifically, particularly relates to a high-efficiency drainage device and method for civil tunnel construction. Background Art

[0002] When constructing a railway, it is often necessary to build a tunnel. Water leakage is inevitable in the constructed railway tunnel. Water leakage to varying degrees may occur in the waterproof layer, detailed structure and other parts, which will affect the progress of railway tunnel construction. When it is necessary to drain the water seepage in the constructed tunnel in time, the construction personnel need to push the water pump to the water seepage place, then connect the suction pipe to the pipe mouth of the water pump suction pipe, and install the drainage pipe at the drainage outlet for drainage treatment.

[0003] 1. Use a water pump to drain the accumulated water to the outside. During the drainage process, the water level will continue to drop gradually. As the liquid level continues to drop, the water inlet end of the water pump may gradually lose the coverage of the water surface, causing the propeller inside the water pump to be partially exposed. The exposed part of the propeller will affect the water intake speed of the water pump, which may lead to a decrease in drainage efficiency.

[0004] 2. When conducting continuous drainage operations, the water level will gradually drop over time. In order to ensure that the water inlet of the water pump can always touch the water surface, especially when conducting drainage operations in areas with a certain slope, we need to constantly adjust the position of the water pump. This frequent adjustment will not only increase labor costs, because someone needs to constantly monitor and move the water pump, but also extend the total drainage time. Each adjustment of the water pump takes a certain amount of time, and the accumulation of this time will result in a longer time for the entire drainage operation. Summary of the invention

[0008] Preferably, a fixed shaft is rotatably mounted on the end of each second fixed plate, a spiral blade is fixedly mounted on the surface of each fixed shaft, two telescopic rods are fixedly mounted on the two side ends of the mounting frame, the top of the two telescopic rods are fixedly mounted on the same support frame, a toothed plate is fixedly mounted on the inner side of each support frame, a driving rod is rotatably mounted inside each support frame, a turntable is fixedly mounted on the top of each driving rod, a first support plate is provided at the bottom end of each support frame, a second support plate is rotatably mounted on the bottom end of each first support plate, and two connecting plates are slidably mounted on the top of each first support plate.

[0009] In a second aspect, the present invention provides an operating method of a high-efficiency drainage device for civil tunnel construction, comprising: Place the mounting bracket in the water-logged area and insert the end of the protective sleeve into the water; When the mounting frame enters the accumulated water, the floating plate and the sleeve slide upwards under the action of buoyancy, pushing the first fixed plate up; the rise of the first fixed plate drives the seat and the compression plate to move, and when the compression plate is compressed to the limit position, the force is transmitted to the docking plate, triggering the pressure sensor; the pressure sensor transmits the signal to the power box, and the motor inside the power box starts, driving the second bevel gear and the gear plate to rotate; the second bevel gear contacts the two first bevel gears, driving the transmission shaft to rotate at the side end of the protective sleeve, thereby driving the fixed shaft and the spiral blade to rotate; the rotating spiral blade drains the accumulated water upward and discharges it through the connecting sleeve and the drain pipe; When the flow of accumulated water inside the protective sleeve weakens, the conical tube slides toward the inside of the fixed sleeve under its own force, driving the first plug plate to dock with the second plug plate; the docking of the first plug plate and the second plug plate forms an extrusion docking structure, which transmits the signal to the power box, and the control main board stops the motor drive after receiving the signal; when the accumulated water is drained, the water pump is automatically shut down by the movement of the conical tube.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the hydraulic rod drives the second bevel gear and the gear plate to slide downward, and the surface of the second bevel gear is disconnected from the first bevel gear, while the gear plate moves downward, and the bottom end of the gear plate is connected with the surfaces of the two tooth plates. The power box drives the gear plate to rotate, and the rotating gear plate rubs against the surfaces of the tooth plates, so that the mounting frame moves horizontally at the side ends of the two support frames. Through the deflection direction of the first fixed plate at the end of the directional slide plate, we can drive the mounting frame to move to that side. When used in a water-accumulated area with an inclined surface, we can let the mounting frame drive the protective cover to move to an area with deeper water accumulation according to the changes in the water accumulation, so as to ensure the continuity of drainage.

[0011] In the present invention, the sliding of the conical cylinder drives the first plug plate to move toward the inside of the second plug plate, and the first plug plate and the second plug plate are docked with each other to form an extrusion docking structure, which transmits a signal to the power box. After the control main board inside the power box receives the signal, the motor drives the impeller spiral blades to stop rotating. After the accumulated water is drained, the water pump can be automatically shut down by the movement of the conical cylinder to prevent the spiral blades from idling, thereby achieving the purpose of energy saving and equipment protection.

[0012] In the present invention, the top end of the connecting plate is connected to the supporting frame part, and the connecting plate slides on the top end of the first support plate. The movement of the first support plate is assisted by the connecting plate to guide and support it. As the first support plate slides down, the second support plate part can rotate at the bottom end of the first support plate to adapt to different terrain conditions. By controlling the rotation of the two driving rods respectively, the moving distances of the two first support plates can be adjusted respectively, thereby achieving effective placement of water accumulation points on different terrains.

[0013] In the present invention, by allowing the docking plate to slide downward along the guide frame, the two pressure sensors installed on the top of the docking plate are released from the squeezed state, driving the hydraulic rod to extend and retract, allowing the hydraulic rod to drive the second bevel gear and the gear plate to slide downward, and at the same time, the surface of the second bevel gear is disconnected from the first bevel gear, and the gear plate moves downward, and the bottom end of the gear plate is docked with the surfaces of the two tooth plates. The power box drives the gear plate to rotate, and the rotating gear plate rubs against the surface of the tooth plate. The power box can drive the two protective covers and allow the mounting frame to move a short distance at the same time.

[0014] In the present invention, after the mounting frame is put into the accumulated water, since the interior of the float plate and the sleeve are both hollow in design, and the end of the sleeve is conical in design to increase the contact surface, the sleeve slides upward inside the float plate under the buoyancy, so that the sleeve applies an upward thrust to the float plate. At the same time, the float plate itself also has a certain buoyancy. The two float plates are symmetrically installed on the side ends of the first fixed plate. The buoyancy generated at the same time allows the first fixed plate to move upward, so that the first fixed plate is in a stable sliding state, thereby preventing the first fixed plate from deviating at an excessive angle.

DETAILED DESCRIPTION

[0017] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0018] See also Figure 1 - Fig. 9 The present invention provides a high-efficiency drainage device for civil engineering tunnel construction, including a mounting frame 11, wherein two protective sleeves 23 are fixedly installed inside the mounting frame 11, a second fixed plate 41 is fixedly installed inside each protective sleeve 23, a fixed sleeve 39 is fixedly installed on the top of each second fixed plate 41, a second plug plate 38 is fixedly installed on the top of each fixed sleeve 39, a first plug plate 37 is slidably installed on the top of each second plug plate 38, a conical cylinder 36 is fixedly installed on the top of each first plug plate 37, and the conical cylinder 36 slides upward at a distance on the top of the fixed sleeve 39. However, when the accumulated water contacted by the end of the protective sleeve 23 is reduced, the accumulated water flow inside the protective sleeve 23 will also be weakened accordingly, thereby causing the cone to be drained. The impact force formed by the conical cylinder 36 is also weakened. In this case, the conical cylinder 36 will slide towards the inside of the fixed sleeve 39 under its own force. As the conical cylinder 36 slides, it will drive the first plug plate 37 to move towards the inside of the second plug plate 38. The first plug plate 37 and the second plug plate 38 are docked with each other to form an extrusion docking structure to transmit the signal to the power box 14. Two guide frames 26 are fixedly installed at the top and bottom of the mounting frame 11. The same directional slide plate 25 is slidably installed on the inner sides of the two guide frames 26. The first fixed plate 27 is rotatably installed at the end of the directional slide plate 25. The power box 14 is fixedly installed at the top of the mounting frame 11, and the filter plate 24 is fixedly installed at the bottom end of each protective sleeve 23.

[0019] The two side ends of the first fixed plate 27 are fixedly installed with floating plates 28, and at least two sleeves 44 are slidably installed on the surface of each floating plate 28. After the mounting frame 11 enters the inside of the accumulated water, since the inside of the floating plate 28 and the sleeve 44 are both hollow, and the end of the sleeve 44 is conical, the contact surface is increased. The sleeve 44 is subjected to buoyancy and slides upward inside the floating plate 28, so that the sleeve 44 applies an upward thrust to the floating plate 28. At the same time, the floating plate 28 itself also has a certain buoyancy. The two floating plates 28 are symmetrically installed on the side ends of the first fixed plate 27, and the buoyancy generated at the same time allows the first fixed plate 27 to move upward. The first fixing plate 27 slides inside the two guide frames 26, and the side end of each second fixing plate 41 is penetrated by a transmission shaft 31, and the top of each transmission shaft 31 is fixedly installed with a first bevel gear 32. A hydraulic rod 35 is arranged inside the mounting frame 11, and a gear plate 34 is rotatably installed on the top of the hydraulic rod 35, and a second bevel gear 33 is fixedly installed on the top of the gear plate 34. A connecting sleeve 12 is fixedly installed on the top of each protective sleeve 23, and a drain pipe 13 is fixedly installed on the top of each connecting sleeve 12. Two card seats 45 are fixedly installed on the top of the first fixing plate 27, and each A compression plate 46 is rotatably mounted on the top of the holder 45, a docking plate 47 is slidably mounted on the side end of each guide frame 26, and a pressure sensor 48 is fixedly mounted on the top of each docking plate 47. The holder 45 applies a thrust to the end of the compression plate 46, so that the end of the compression plate 46 is first compressed by force. After the compression plate 46 is compressed to the limit position, the top of the compression plate 46 transmits the force to the docking plate 47, so that the docking plate 47 slides on the side end of the guide frame 26. At the same time, a pressure sensor 48 is installed on the top of the docking plate 47. The pressure sensor 48 is a squeeze contact mechanism. Through the directional slide plate 2 The connecting line installed at the top is connected to the power box 14. The control main board and the driving motor are installed inside the power box 14. At the same time, the motor drives the second bevel gear 33 and the gear plate 34 to rotate. The surfaces of the two first bevel gears 32 are in contact with the second bevel gear 33, driving the transmission shaft 31 to rotate at the side end of the protective sleeve 23. The end of the transmission shaft 31 passes through the protective sleeve 23 and is connected to the fixed shaft 42 through a gear. The rotating fixed shaft 42 drives the spiral blade 43 to rotate inside the protective sleeve 23. The filter plate 24 is installed at the end and outside of the protective sleeve 23, and the filter plate 24 plays an interception role.

[0020] A fixed shaft 42 is rotatably mounted on the end of each second fixed plate 41, and a spiral blade 43 is fixedly mounted on the surface of each fixed shaft 42. The accumulated water is effectively drained upward by the high-speed rotating spiral blade 43. In this process, the accumulated water impacts upward inside the protective sleeve 23, directly exerting a strong impact force on the end of the conical cylinder 36. This impact force exerts a fixed direction of force on the conical cylinder 36, causing the conical cylinder 36 to slide upward for a distance at the top of the fixed sleeve 39. However, when the accumulated water contacted by the end of the protective sleeve 23 decreases, the accumulated water flow inside the protective sleeve 23 will also be weakened accordingly, thereby causing the impact force on the conical cylinder 36 to be weakened. In this case, the conical cylinder 36 is Under the action of the body, it will slide toward the inside of the fixed sleeve 39. As the conical cylinder 36 slides, it will drive the first plug plate 37 to move toward the inside of the second plug plate 38. Two telescopic rods 21 are fixedly installed on the two side ends of the mounting frame 11, and the tops of the two telescopic rods 21 are fixedly installed with the same support frame 15. A toothed plate 29 is fixedly installed on the inner side of each support frame 15. A driving rod 17 is rotatably installed inside each support frame 15, and a turntable 16 is fixedly installed on the top of each driving rod 17. A first support plate 18 is provided at the bottom end of each support frame 15, and a second support plate 19 is rotatably installed at the bottom end of each first support plate 18. Two connecting plates 22 are slidably installed on the top of each first support plate 18.

[0021] Working principle: The first step is to connect the top of the drain pipe 13 to the delivery pipe when using the device. Then, the operator needs to move the mounting frame 11 as a whole, and use the movement of the mounting frame 11 to drive the support frame 15 to move accordingly, and place the mounting frame 11 at an appropriate position in the water accumulation area to ensure that it can function effectively. Next, by rotating the turntable 16, since the end of the turntable 16 has been fixedly installed with a driving rod 17, the rotation of the turntable 16 will drive the driving rod 17 to rotate inside the support frame 15. The end of the driving rod 17 is designed with a structure that passes through the inside of the first support plate 18, so that the inside of the first support plate 18 can fit tightly with the surface of the driving rod 17. When the driving rod 17 rotates, it will The support plate 18 applies a downward thrust, causing the first support plate 18 to slide smoothly downward at the bottom end of the support frame 15. At the same time, the top end of the connecting plate 22 is connected to the support frame 15. The connecting plate 22 slides at the top end of the first support plate 18, and the movement of the first support plate 18 is assisted by the connecting plate 22. Guide and support. As the first support plate 18 slides down, the second support plate 19 can be rotated at the bottom end of the first support plate 18 to adapt to different terrain conditions. By controlling the rotation of the two driving rods 17 respectively, the moving distances of the two first support plates 18 can be adjusted respectively, thereby achieving effective placement of water accumulation points on different terrains. In this way, it can be ensured that the end of the protective cover 23 is smoothly inserted into the inside of the water accumulation to achieve the expected working effect.

[0022] After the mounting frame 11 enters the accumulated water, since the interior of the floating plate 28 and the sleeve 44 are both hollow in design, and the end of the sleeve 44 is conical in design to increase the contact surface, the sleeve 44 slides upward inside the floating plate 28 under the buoyancy, allowing the sleeve 44 to apply an upward thrust to the floating plate 28. At the same time, the floating plate 28 itself also has a certain buoyancy. The two floating plates 28 are symmetrically installed at the side ends of the first fixed plate 27. The buoyancy generated at the same time allows the first fixed plate 27 to move upward. The first fixed plate 27 slides inside the two guide frames 26. At the same time, the first fixed plate 27 drives the holder 45 to move upward. The holder 45 applies a thrust to the end of the compression plate 46, allowing the end of the compression plate 46 to be compressed first. After the compression plate 46 is compressed to the limit position, the top end of the compression plate 46 transmits the force to the docking plate 47, allowing the docking plate 47 to slide on the side ends of the guide frame 26. At the same time, a pressure sensor 48 is installed at the top end of the docking plate 47. The pressure sensor 48 is a squeeze contact mechanism, which is connected to the power box 14 through a connecting line installed at the top of the directional slide plate 25. A control mainboard and a drive motor are installed inside the power box 14. At the same time, the motor drives the second bevel gear 33 and the gear plate 34 to rotate. The surfaces of the two first bevel gears 32 are in contact with the second bevel gear 33, driving the transmission shaft 31 to rotate at the side end of the protective sleeve 23. The end of the transmission shaft 31 passes through the protective sleeve 23 and is connected to the fixed shaft 42 through a gear. The rotating fixed shaft 42 drives the spiral blade 43 to rotate inside the protective sleeve 23. Filter plates 24 are installed at the end and outside of the protective sleeve 23. The filter plates 24 play an interception role to prevent the stone crushing device from entering the interior of the protective sleeve 23 and damaging the spiral blade 43. At the same time, the rotating spiral blade 43 transports the accumulated water to the interior of the connecting sleeve 12. At the same time, the two connecting sleeves 12 are simultaneously connected to the drain pipe 13, and the drain pipe 13 discharges the accumulated water.

[0023] In the second step, the accumulated water is effectively drained upward by the high-speed rotating spiral blades 43. In this process, the accumulated water impacts upward inside the protective sleeve 23, directly exerting a strong impact force on the end of the conical cylinder 36. This impact force exerts a fixed direction of force on the conical cylinder 36, causing the conical cylinder 36 to slide upward for a distance at the top of the fixed sleeve 39. However, when the accumulated water contacted by the end of the protective sleeve 23 decreases, the accumulated water flow inside the protective sleeve 23 will also be weakened accordingly, resulting in a weakened impact force on the conical cylinder 36. In this case, the conical cylinder Under its own force, 36 will slide toward the inside of the fixed sleeve 39. As the conical tube 36 slides, it will drive the first plug plate 37 to move toward the inside of the second plug plate 38. The first plug plate 37 and the second plug plate 38 are docked with each other to form an extrusion docking structure, which transmits the signal to the power box 14. After receiving the signal, the control motherboard inside the power box 14 will stop the rotation of the motor-driven impeller spiral blades 43. After the accumulated water is drained, the water pump can be automatically turned off through the movement of the conical tube 36 to prevent the spiral blades 43 from idling, thereby achieving the purpose of energy saving and equipment protection.

[0024] Through the cooperation of the two supporting frames 15, the mounting frame 11 is erected as a whole inside the water pit, and the two protective sleeves 23 continuously discharge the accumulated water to the outside. At the same time, a driving motor is installed inside the power box 14, and one end of the motor is connected to the gear plate 34. A transmission shaft 31 is installed on the top of the gear plate 34. The transmission shaft 31 is a retractable structure. When the transmission shaft 31 rotates, the second bevel gear 33 and the gear plate 34 are moved vertically for a short distance inside the mounting frame 11. When the accumulated water under the protective sleeve 23 is drained, the water level of the accumulated water drops, and at the same time, the force exerted on the floating plate 28 and the sleeve 44 is weakened. The sleeve 44 and the floating plate 28 drive the first fixed plate 27 to move downward, so that the first fixed plate 27 applies a downward force to the directional slide plate 25, and the directional slide plate 25 slides downward on the inner side of the two guide frames 26. At the same time, the first fixed plate 27 drives the holder 45 to move downward, so that the holder 45 pulls the end of the compression plate 46. By compressing The plate 46 exerts a downward force on the docking plate 47, allowing the docking plate 47 to slide downward along the guide frame 26. The two pressure sensors 48 installed on the top of the docking plate 47 are released from the squeezed state, driving the hydraulic rod 35 to retract and retract, allowing the hydraulic rod 35 to drive the second bevel gear 33 and the gear plate 34 to slide downward. While the surface of the second bevel gear 33 is disconnected from the first bevel gear 32, the gear plate 34 moves downward, and the bottom end of the gear plate 34 is docked with the surfaces of the two tooth plates 29. The power box 14 drives the gear plate 34 to rotate, and the rotating gear plate 34 rubs against the surface of the tooth plates 29, allowing the mounting frame 11 to move horizontally at the side ends of the two support frames 15, and the first fixed plate 27 is driven to move to that side through the deflection direction of the first fixed plate 27 at the end of the directional slide plate 25. When used in a water accumulation area with an inclined surface, the mounting frame 11 can drive the protective cover 23 to move to an area with deeper water accumulation by itself according to the change of the water accumulation, thereby ensuring the continuity of drainage.

[0025] Optionally, the method for operating the high-efficiency drainage device for civil tunnel construction comprises: Step 1: Preparation and Installation Connect the top of the drain pipe 13 to the delivery pipe. Move the mounting frame 11 as a whole and place it at a suitable position in the water accumulation area. By rotating the turntable 16, adjust the positions of the first support plate 18 and the second support plate 19 to ensure that the end of the protective sleeve 23 is smoothly inserted into the water accumulation.

[0026] Step 2: Startup and drainage When the mounting frame 11 enters the accumulated water, the floating plate 28 and the sleeve 44 slide upward due to the buoyancy, pushing the first fixed plate 27 up. The rise of the first fixed plate 27 drives the seat 45 and the compression plate 46 to move. When the compression plate 46 is compressed to the limit position, the force is transmitted to the docking plate 47, triggering the pressure sensor 48. The pressure sensor 48 transmits the signal to the power box 14, and the motor inside the power box 14 starts, driving the second bevel gear 33 and the gear plate 34 to rotate. The second bevel gear 33 contacts the two first bevel gears 32, driving the transmission shaft 31 to rotate at the side end of the protective sleeve 23, thereby driving the fixed shaft 42 and the spiral blade 43 to rotate. The rotating spiral blade 43 drains the accumulated water upward and discharges it through the connecting sleeve 12 and the drain pipe 13.

[0027] Step 3: Automatic adjustment and energy saving When the flow of accumulated water inside the protective sleeve 23 weakens, the conical cylinder 36 slides toward the inside of the fixed sleeve 39 under its own force, driving the first plug plate 37 to dock with the second plug plate 38. The docking of the first plug plate 37 and the second plug plate 38 forms an extrusion docking structure, which transmits a signal to the power box 14, and the control main board stops the motor drive after receiving the signal. When the accumulated water is drained, the water pump is automatically turned off by the movement of the conical cylinder 36 to prevent the spiral blade 43 from idling, thereby achieving the purpose of energy saving and equipment protection.

[0028] Step 4: Move and adapt As the accumulated water is drained, the force on the floating plate 28 and the sleeve 44 is weakened, driving the first fixed plate 27 to move downward. The descent of the first fixed plate 27 generates a downward force on the docking plate 47 through the clamping seat 45 and the compression plate 46, causing the docking plate 47 to slide downward along the guide frame 26. The power box 14 drives the hydraulic rod 35 to extend and retract, disconnecting the second bevel gear 33 from the first bevel gear 32, and at the same time, the gear plate 34 moves downward to contact the tooth plate 29. The power box 14 drives the gear plate 34 to rotate, and through the friction between the gear plate 34 and the tooth plate 29, the mounting frame 11 moves horizontally at the side ends of the two support frames 15 to adapt to the changes in the accumulated water.
