Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel waterproof drainage, and particularly relates to a tunnel drainage structure. Background Technique

[0002] Tunnel waterproof drainage refers to taking a series of measures to prevent water penetration and accumulation during tunnel construction to ensure the safety and smoothness of the tunnel. These measures include using waterproof materials, setting up drainage systems, and conducting geological surveys. When carrying out waterproof drainage on both sides of an actual tunnel, since the gap size on the filter plate is generally fixed, it is rather troublesome to clean the gaps between the filter plates, and blockages are likely to occur, thereby reducing the filtering effect of the filter plate. Content of the Utility Model

[0003] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a tunnel drainage structure.

[0004] To solve the above problems, the utility model adopts the following technical solutions:

[0005] A tunnel drainage structure includes a tunnel lining. Two drainage grooves are formed on the surface of the tunnel lining. Adjusting devices are arranged on the surfaces of the two drainage grooves. The adjusting device includes two fixing plates, both of which are fixedly connected to the drainage grooves. A lead screw is threadedly connected to the surface of the fixing plate. One end of the lead screw is rotatably connected to a connecting plate. A plurality of limiting blocks are fixedly connected to the surface of the connecting plate. Two sliding rods are fixedly connected to the surface of the drainage groove. A plurality of filter plates are slidably connected to the arc surfaces of the two sliding rods. A plurality of filter plates are all slidably connected to the limiting blocks. By setting the adjusting device, through the cooperation among the fixing plate, the lead screw, the connecting plate, the limiting block, the sliding rod and the filter plate, the size of the gap between the filter plates can be adjusted, avoiding the single and fixed gap size between the filter plates, which is rather troublesome to clean the gaps between the filter plates and is likely to be blocked, thereby reducing the filtering effect of the filter plate. This device can adjust the position between the filter plates, improve the cleaning effect on the gaps inside the filter plates, and further improve the filtering effect of the filter plate.

[0006] Preferably, an elastic rope is fixedly connected to the surface of the filter plate. A guiding frame is slidably connected to the arc surface of the elastic rope. The guiding frame is fixedly connected to the tunnel lining. The stop block will drive one end of the elastic rope to move, and then the elastic rope will drive the filter plate to move. At this time, the elastic rope can facilitate the quick reset of the filter plate.

[0007] Preferably, a stop block is fixedly connected to one end of the elastic rope. The cross section of the stop block is circular. The elastic rope will drive the stop block to move. At this time, the stop block can prevent the elastic rope from falling off the guiding frame.

[0008] Preferably, two telescopic rods are fixedly connected to the surface of the fixed plate, and both of the telescopic rods are fixedly connected to the connecting plate. The connecting plate drives one end of the telescopic rod to move. At this time, the telescopic rod can prevent the connecting plate from rotating along with the rotation of the screw rod.

[0009] Preferably, an auxiliary block is fixedly connected to the surface of the limiting block. The vertical cross-section of the auxiliary block is trapezoidal. The limiting block drives the auxiliary block to move. At this time, the auxiliary block with a trapezoidal vertical cross-section can facilitate the limiting block to enter the gap between the filter plates.

[0010] Preferably, a positioning seat is fixedly connected to the surface of the screw rod. A rectangular rod is slidably connected to the inner wall of the positioning seat. A turning handle is fixedly connected to the surface of the rectangular rod. When the rectangular rod is inserted into the positioning seat, at this time, rotate the turning handle, and then the turning handle drives the rectangular rod to rotate. Then the rectangular rod drives the positioning seat to rotate. At this time, the positioning seat drives the screw rod to rotate. At this time, the turning handle, the rectangular rod and the positioning seat can facilitate the staff to rotate the screw rod.

[0011] Preferably, a spring is rotatably connected to the surface of the turning handle, and the other end of the spring is fixedly connected to the positioning seat. When the limiting block enters the gap between the filter plates, stop rotating the turning handle. At this time, the spring uses its outward elastic force to eject the turning handle and the rectangular rod from the positioning seat. At this time, the spring can idle under the influence of external forces when the turning handle is not in use, and at the same time prevent the turning handle from being lost.

[0025] Next, specifically describe the specific settings and functions of its adjusting device 3.

[0026] As Figures 2-5 shown, the adjusting device 3 includes two fixing plates 301, both of the two fixing plates 301 are fixedly connected to the drainage groove 2, a lead screw 302 is threadedly connected to the surface of the fixing plate 301, one end of the lead screw 302 is rotatably connected to a connecting plate 303, several limiting blocks 304 are fixedly connected to the surface of the connecting plate 303, two sliding rods 305 are fixedly connected to the surface of the drainage groove 2, several filter plates 306 are slidably connected to the arc surfaces of the two sliding rods 305, several filter plates 306 are all slidably connected to the limiting blocks 304, an elastic cord 307 is fixedly connected to the surface of the filter plate 306, a guide frame 308 is slidably connected to the arc surface of the elastic cord 307, the guide frame 308 is fixedly connected to the tunnel lining 1, the stop block 309 will drive one end of the elastic cord 307 to move, and then the elastic cord 307 will drive the filter plate 306 to move. At this time, the elastic cord 307 can facilitate the quick reset of the filter plate 306. One end of the elastic cord 307 is fixedly connected to a stop block 309, the cross section of the stop block 309 is circular, the elastic cord 307 will drive the stop block 309 to move. At this time, the stop block 309 can prevent the elastic cord 307 from falling off the guide frame 308. Two telescopic rods 310 are fixedly connected to the surface of the fixing plate 301, both of the two telescopic rods 310 are fixedly connected to the connecting plate 303, the connecting plate 303 will drive one end of the telescopic rod 310 to move. At this time, the telescopic rod 310 can prevent the connecting plate 303 from rotating as the lead screw 302 rotates. An auxiliary block 311 is fixedly connected to the surface of the limiting block 304, the vertical section of the auxiliary block 311 is trapezoidal, the limiting block 304 will drive the auxiliary block 311 to move. At this time, the auxiliary block 311 with a trapezoidal vertical section can facilitate the limiting block 304 to enter the gap between the filter plates 306. A positioning seat 312 is fixedly connected to the surface of the lead screw 302, a rectangular rod 313 is slidably connected to the inner wall of the positioning seat 312, a turning handle 314 is fixedly connected to the surface of the rectangular rod 313. When the rectangular rod 313 is inserted into the positioning seat 312, at this time, rotate the turning handle 314, and then the turning handle 314 will drive the rectangular rod 313 to rotate. Then the rectangular rod 313 will drive the positioning seat 312 to rotate. At this time, the positioning seat 312 will drive the lead screw 302 to rotate.

A spring 315 is rotatably connected to the surface of the turning handle 314, and the other end of the spring 315 is fixedly connected to the positioning seat 312.

[0027] The effects achieved by the above components are as follows: when the limit block 304 enters the gap between the filter plates 306, the rotation of the throttle grip 314 stops.

At this time, the spring 315 can rotate freely under the influence of external forces when the throttle grip 314 is not in use, and at the same time prevent the throttle grip 314 from being lost.

[0028] Working principle: when it is necessary to adjust the gap between the filter plates 306, first move the turning handle 314 towards the direction close to the filter plate 306, at this time the turning handle 314 will drive the rectangular rod 313 to be inserted into the positioning seat 312, and at the same time the turning handle 314 will squeeze the spring 315, at this time the spring 315 will generate an outward elastic force, and then when the rectangular rod 313 is inserted into the positioning seat 312, the turning handle 314 is turned at this time, and then the turning handle 314 will drive the rectangular rod 313 to rotate, and then the rectangular rod 313 will drive the positioning seat 312 to rotate, and at this time the positioning seat 312 will drive the screw rod 302 to rotate, and at this time the turning handle 314, the rectangular rod 313 and the positioning seat 312 can facilitate the staff to rotate the screw rod 302, and then the screw rod 302 will The screw rod 302 will drive the connecting plate 303 to move, and then the connecting plate 303 will drive one end of the telescopic rod 310 to move. At this time, the telescopic rod 310 can place the connecting plate 303 to rotate along with the rotation of the screw rod 302, and then the connecting plate 303 will drive the limiting block 304 to be pulled out from the gap between the filter plates 306. Then, when the limiting block 304 is separated from the filter plate 306, the size of the gap between the filter plates 306 can be adjusted by toggling the filter plate 306, so as to clean the filtered matter between the gaps of the filter plates 306. At the same time, when the filter plate 306 is toggled, the filter plate 306 will drive the elastic rope 307 The filter plate 306 is moved in the direction close to the filter plate 306. At this time, the elastic rope 307 moves along the guide frame 308. At the same time, the elastic rope 307 drives the block 309 to move. At this time, the block 309 can prevent the elastic rope 307 from falling off the guide frame 308. Then, when the cleaning is completed, the block 309 can be pulled in the direction away from the guide frame 308. At this time, the block 309 drives one end of the elastic rope 307 to move, and then the elastic rope 307 drives the filter plate 306 to move. At this time, the elastic rope 307 can facilitate the filter plate 306 to quickly reset, and then the handle 314 is rotated in the opposite direction. At this time, the handle 314 drives the rectangular rod 313 to move, and then the rectangular rod 313 drives the positioning seat 312 to move. 12 will drive the screw rod 302 to move along the surface of the fixing plate 301 towards the direction close to the filter plate 306. At this time, the screw rod 302 will drive the connecting plate 303 to move, and then the connecting plate 303 will drive the limit block 304 to move. At the same time, the limit block 304 will drive the auxiliary block 311 to move. At this time, the auxiliary block 311 with a trapezoidal vertical cross-section can facilitate the limit block 304 to enter the gap between the filter plates 306. When the limit block 304 enters the gap between the filter plates 306, the rotation of the turning handle 314 is stopped. At this time, the spring 315 will use its own outward elastic force to drive the rectangular rod 313 to pop out from the positioning seat 312. At this time, the spring 315 can be affected by external force to idle when the turning handle 314 is not in use.Meanwhile, to prevent the throttle grip 314 from being lost, the filter plate 306 can be positioned at this time. By setting the adjusting device 3, through the cooperation among the fixing plate 301, the lead screw 302, the connecting plate 303, the limiting block 304, the sliding rod 305 and the filter plate 306, the size of the gap between the filter plates 306 can be adjusted, avoiding the single and fixed size of the gap between the filter plates 306, which makes it troublesome to clean the gap between the filter plates 306 and is prone to blockage, thus reducing the filtering effect of the filter plate 306. This device can adjust the position between the filter plates 306, improve the cleaning effect of the gap inside the filter plate 306, and further improve the filtering effect of the filter plate 306.
