Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of construction drainage, and more particularly relates to a high-efficiency drainage device and method for civil tunnel construction. BACKGROUND

[0002] When a railway is built, a tunnel is often needed to be built, and leakage of water in the built railway tunnel is inevitable. The waterproof layer, the detailed structure and other parts may all have different degrees of water leakage, which will affect the progress of the railway tunnel construction. When the water leakage in the construction tunnel needs to be promptly drained, the construction personnel need to push the water pump to the water leakage position, then connect the water suction pipe to the pipe opening of the water suction pipe of the water pump, and install the drainage pipe at the drainage opening to drain the water.

[0003] 1. The accumulated water is discharged outward by the water pump. During the drainage process, the water level will gradually decrease. As the liquid level continues to decrease, the water inlet end of the water pump may gradually lose the coverage of the water surface, causing the paddle part inside the water pump to be exposed. The exposed part of the paddle will affect the water inlet speed of the water pump, which may further reduce the drainage efficiency.

[0004] 2. When the continuous drainage operation is performed, the water surface of the accumulated water will gradually decrease over time. In order to ensure that the water inlet of the water pump can always contact the water surface, especially when the drainage operation is performed in an area with a certain slope, we need to constantly adjust the position of the water pump. This frequent adjustment not only increases the labor cost, as someone needs to constantly monitor and move the water pump, but also prolongs the total drainage time. Each time the water pump is adjusted, a certain amount of time is spent, and these accumulated times will cause the entire drainage operation time to be prolonged. SUMMARY

[0033] Working principle:

[0034] First, in use of the device, first need to connect the top end of the drain pipe 13 to the delivery pipeline, then, the operator needs to move the mounting frame 11 as a whole, using the mounting frame 11 to drive the support frame 15 to move accordingly, place the mounting frame 11 in the appropriate position of the water accumulation area, ensure that it can effectively play a role, next, through the rotation of the component turntable 16, because the end of the turntable 16 has been fixedly installed with the drive rod 17, so the rotation of the turntable 16 will drive the drive rod 17 to rotate inside the support frame 15, the end of the drive rod 17 is designed to pass through the inside of the first branch plate 18, so that the inside of the first branch plate 18 can be closely fitted with the surface of the drive rod 17, when the drive rod 17 rotates, it will exert a downward thrust on the first branch plate 18, prompting the first branch plate 18 to smoothly slide downward at the bottom end of the support frame 15, at the same time, the top end of the connecting plate 22 is connected with the support frame 15, the connecting plate 22 slides at the top end of the first branch plate 18, and the movement of the first branch plate 18 is assisted by the connecting plate 22, with the downward sliding of the first branch plate 18, the second branch plate 19 can rotate at the bottom end of the first branch plate 18 to adapt to different terrain conditions, by controlling the rotation of the two drive rods 17 respectively, the moving distance of the two first branch plates 18 can be adjusted respectively, so as to effectively place the different terrain water accumulation points, in this way, it can ensure that the end of the protective sleeve 23 is smoothly inserted into the inside of the water accumulation, and the expected working effect is achieved.

[0035] After the installation frame 11 enters the interior of the accumulated water, because the floating plate 28 and the interior of the sleeve 44 are hollow designs, and the end of the sleeve 44 is a tapered design, increasing the contact surface, the sleeve 44 is subjected to buoyancy and slides upward in the interior of the floating plate 28, allowing the sleeve 44 to exert an upward thrust on the floating plate 28, and 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, and the generated buoyancy allows the first fixed plate 27 to move upward, the first fixed plate 27 slides in the interior of the two guide frames 26, and at the same time, the first fixed plate 27 drives the clamping seat 45 to move upward, the clamping seat 45 exerts a thrust on the end of the compression plate 46, allowing the end of the compression plate 46 to be compressed first under stress, after the compression plate 46 is compressed to the limit position, the top end of the compression plate 46 transmits the force to the butt joint plate 47, allowing the butt joint plate 47 to slide at the side ends of the guide frame 26, and at the same time, the pressure sensor 48 is installed at the top end of the butt joint plate 47, the pressure sensor 48 is a kind of extrusion contact mechanism, connected with the power box 14 through the connecting line installed at the top end of the directional sliding plate 25, and the control mainboard and the driving motor are installed in the interior of the power box 14, at the same time, the motor drives the second bevel gear 33 and the gear disc 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 ends of the protective sleeve 23, the end of the transmission shaft 31 penetrates the protective sleeve 23, connected with the fixed shaft 42 through the gear, the rotating fixed shaft 42 drives the helical blade 43 to rotate in the interior of the protective sleeve 23, the filter plate 24 is installed at the end and the outside of the protective sleeve 23, which plays a blocking role to prevent the stone device from entering the interior of the protective sleeve 23 and damaging the helical blade 43, at the same time, the rotating helical blade 43 transports the accumulated water into the interior of the connecting sleeve 12, and at the same time, the two connecting sleeves 12 are connected with the drain pipe 13, which discharges the accumulated water.

[0036] Second, by high-speed rotating spiral blade 43, the water is effectively drained upward, in the process, the water in the inside of the protective sleeve 23 upward impact, directly to the end of the cone cylinder 36 exert a strong impact force, the impact force on the cone cylinder 36 exerted a fixed direction of force, so that the cone cylinder 36 in the fixed sleeve 39 top up a distance, however, when the protective sleeve 23 end contact the water is reduced, the water flow inside the protective sleeve 23 will also be reduced accordingly, resulting in the impact force on the cone cylinder 36 also weakened, in this case, the cone cylinder 36 in its own force, will be to the inside of the fixed sleeve 39 sliding, along with the sliding of the cone cylinder 36, it will drive the first plug-in plate 37 to the inside of the second plug-in plate 38, the first plug-in plate 37 and the second plug-in plate 38 are mutually interfaced, forming a extrusion interface structure, the signal to the power box 14, the control board inside the power box 14 receives the signal, will stop the motor drive impeller spiral blade 43 rotation, after the water is drained, through the movement of the cone cylinder 36, can automatically close the water pump, to prevent the spiral blade 43 idling, so as to achieve the purpose of energy saving and protection equipment.

[0037] By the cooperation of the two support frames 15, the mounting frame 11 is erected as a whole inside the water pit, and the two protective sleeves 23 continuously discharge water outside, while the power box 14 is internally provided with a driving motor, one end of the motor is connected with the gear plate 34, a transmission shaft 31 is installed at the top end of the gear plate 34, the transmission shaft 31 is a telescopic structure, and the transmission shaft 31 rotates while allowing the second bevel gear 33 and the gear plate 34 to move vertically for a short distance inside the mounting frame 11. When the water under the protective sleeve 23 is discharged, the water surface drops, and the force acting on the floating plate 28 and the sleeve 44 weakens, so that the sleeve 44 and the floating plate 28 drive the first fixed plate 27 to move downward, so that the first fixed plate 27 exerts a downward force on the directional sliding plate 25, and the directional sliding plate 25 slides downward inside the two guide frames 26, and the first fixed plate 27 drives the clamping seat 45 to move downward, so that the clamping seat 45 pulls the end of the compression plate 46, and the compression plate 46 exerts a downward force on the butt plate 47, so that the butt plate 47 slides downward along the guide frame 26, and the two pressure sensors 48 installed at the top end of the butt plate 47 are released from the extrusion state, and the driving hydraulic rod 35 is telescopic, so that the hydraulic rod 35 drives the second bevel gear 33 and the gear plate 34 to slide downward, the surface of the second bevel gear 33 is disconnected from the first bevel gear 32, and the gear plate 34 moves downward, the bottom end of the gear plate 34 is connected with the surface of the two toothed plates 29, the power box 14 drives the gear plate 34 to rotate, the rotating gear plate 34 rubs with the surface of the toothed plate 29, and the mounting frame 11 moves horizontally at the side end of the two support frames 15, the first fixed plate 27 deflects at the end of the directional sliding plate 25, and drives the mounting frame 11 to move to that side. When used in a water area with a slope, the mounting frame 11 can drive the protective sleeve 23 to move to a deeper water area according to the change of the water, so as to ensure the continuity of drainage.

[0038] Optionally, the operation method of the high-efficiency drainage device for civil tunnel construction comprises the following steps:

[0039] Step one: preparation and installation

[0040] The top end of the drainage pipe 13 is connected to the conveying pipeline. The mounting frame 11 is moved as a whole and placed at a proper position in the water area. By rotating the turntable 16, the positions of the first branch plate 18 and the second branch plate 19 are adjusted to ensure that the end of the protective sleeve 23 is smoothly inserted into the inside of the water.

[0041] Step two: start and drain

[0042] When the installation frame 11 enters the inside of the accumulated water, the floating plate 28 and the sleeve 44 are upwardly slid under the action of the buoyancy, and push the first fixed plate 27 to rise. The rising of the first fixed plate 27 drives the clamping seat 45 and the compression plate 46 to move, and when the compression plate 46 is compressed to the limit position, the force is transmitted to the butt plate 47, triggering the pressure sensor 48. The pressure sensor 48 transmits a signal to the power box 14, and the motor inside the power box 14 is started to drive the second bevel gear 33 and the gear disc 34 to rotate. The second bevel gear 33 is in contact with the two first bevel gears 32, drives the transmission shaft 31 to rotate at the side end of the protective sleeve 23, and further drives the fixed shaft 42 and the spiral blade 43 to rotate. The rotating spiral blade 43 drains the accumulated water upwardly, and discharges the accumulated water through the connecting sleeve 12 and the drain pipe 13.

[0043] Step three: automatic adjustment and energy saving

[0044] When the flow of the accumulated water in the protective sleeve 23 is weakened, the tapered cylinder 36 slides into the fixed sleeve 39 under the action of the force itself, and drives the first plug plate 37 to butt against the second plug plate 38. The butt joint of the first plug plate 37 and the second plug plate 38 forms a extrusion butt joint structure, transmits a signal to the power box 14, and the control mainboard stops the motor drive after receiving the signal. When the accumulated water is drained, the water pump is automatically closed through the movement of the tapered cylinder 36, so as to prevent the spiral blade 43 from idling, and the purpose of energy saving and protection of the equipment is achieved.

[0045] Step four: movement and adaptation

[0046] With the accumulated water being emptied, the force acting on the floating plate 28 and the sleeve 44 is weakened, driving the first fixed plate 27 to move downwardly. The downward movement of the first fixed plate 27 generates a downward force on the butt plate 47 through the clamping seat 45 and the compression plate 46, so that the butt plate 47 slides downwardly along the guide frame 26. The power box 14 drives the hydraulic rod 35 to extend and retract, so that the second bevel gear 33 is disconnected from the first bevel gear 32, and at the same time, the gear disc 34 moves downwardly and contacts the toothed plate 29. The power box 14 drives the gear disc 34 to rotate, and through the friction between the gear disc 34 and the toothed plate 29, the installation frame 11 moves horizontally at the side end of the two support frames 15, so as to adapt to the change of the accumulated water.
