Description

[0038] In this embodiment, the cross section of the driving block 208 is in the shape of a parallelogram, a plurality of roller sets 2081 are arranged on the upper and lower sides of the driving block 208, the arc surface of the rollers in the roller sets 2081 is attached to the inner wall of the sliding groove on the surface of the rectangular column 206, thereby reducing the friction, the driving block 208 is matched with the size of the sliding groove on the surface of the rectangular column 206, the two driving blocks 208 are symmetrically distributed about the vertical central axis of the reinforcing plate 101, when the two rectangular columns 206 move upward, the two driving blocks 208 move away from each other, i.e. the fixed frame 202 is expanded, so that the sealing gasket 204 is pressed against the tunnel wall, wherein the fixed frame 202 has a certain elasticity and can be expanded, two recesses are arranged on the arc surface of the sealing gasket 204 and are symmetrically distributed about the vertical central axis of the reinforcing plate 101, the plurality of leakage holes 2041 are arranged at the two recesses, and the rectangular column 206 moves upward and pushes the fixed frame 202 to move upward, so that the sealing gasket 204 is pressed against the tunnel wall in a short stroke, i.e. the distance between the sealing gasket 204 and the tunnel wall is relatively short.

[0039] In an optional embodiment, the arc surface of the fixed frame 202 is provided with three grooves 203, the arc surface of the fixed frame 202 is provided with two recesses 205, the two recesses 205 are symmetrically distributed about the vertical central axis of the fixed frame 202, and the sealing gasket 204 is arranged on the arc surface of the fixed frame 202 by means of the three grooves 203 and the two recesses 205.

[0040] It should be noted that the grooves 203 can stabilize the sealing gasket 204 on the surface of the fixed frame 202, and the recesses 205 can discharge the water flow between the tunnel wall and the sealing gasket 204.

[0041] In the initial state, the sealing gasket 204 is not completely extruded on the tunnel wall, and the sealing gasket 204 is close to the tunnel wall. When the sealing gasket 204 is extruded on the tunnel wall, the slide column 304 is coincided with the circular groove 306, the second spring 303 is rebounded, the slide column 304 is clamped into the circular groove 306, the position of the sealing gasket 204 is stabilized, and the position of the sealing gasket 204 is not changed when the subsequent rectangular column 206 moves downward.

[0042] In an optional embodiment, the end surface of the base frame 1 is provided with a rectangular hole 207 matched with the rectangular column 206, the inner wall of the base frame 1 is fixedly connected with a first L-shaped plate 209, one end of the first L-shaped plate 209 is fixedly connected with a square frame 210, the inner wall of the square frame 210 is slidably connected with a rectangular frame 211, the connecting piece 214 is fixedly connected to one end of the rectangular frame 211 away from the driving block 208, the inner wall of the rectangular frame 211 is slidably connected with a sliding block 212, and the inside of the rectangular frame 211 is provided with a first spring 213, both ends of the first spring 213 are fixedly connected with the sliding block 212 and the inner wall of the rectangular frame 211.

[0043] It should be noted that the cross section of the sliding block 212 is in the shape of a convex character, so that the sliding block 212 only moves in one direction. When the rectangular column 206 moves upward, the sliding block 212 moves to the right, and the rectangular frame 211 slides along the inner wall of the square frame 210.

[0044] In an optional embodiment, the end surface of the base frame 1 is provided with a strip-shaped hole 217, the strip-shaped hole 217 is in communication with the rectangular hole 207, the connecting piece 214 penetrates through the top of the base frame 1 through the strip-shaped hole 217, the circular arc surface of the reinforcing plate 101 is provided with two limiting holes 216 matched with the pressing plate 215, the two limiting holes 216 are symmetrically distributed about the vertical center axis of the reinforcing plate 101, both ends of the reinforcing plate 101 are provided with square holes 305, the square holes 305 are in communication with the limiting holes 216, and the surface of the reinforcing plate 101 is provided with two through holes 2161. The through holes 2161 are in communication with the limiting holes 216 and the square holes 305, and correspond to the connecting piece 214.

[0045] Both sides of the connecting piece 214 are fixedly connected with a cylinder 302, the inner wall of the cylinder 302 is slidably connected with a slide column 304, the inside of the cylinder 302 is provided with a second spring 303, both ends of the second spring 303 are fixedly connected with the slide column 304 and the inner wall of the cylinder 302, both sides of the inner wall of the square hole 305 are provided with circular grooves 306 matched with the slide column 304, both sides of the rectangular frame 211 are fixedly connected with limiting blocks 301, and one side of the limiting block 301 away from the driving block 208 is in abutment with the square frame 210.

[0046] It should be noted that the limiting block 301 plays a role in limiting the position of the rectangular frame 211, so that the rectangular frame 211 does not move away from the rectangular column 206 in the opposite direction. In the normal state, the second spring 303 is in the compressed state, and the sliding column 304 is pressed against the inner wall of the square hole 305. When the sealing gasket 204 is pressed against the tunnel wall, the sliding column 304 coincides with the circular groove 306, and the sliding column 304 is clamped into the circular groove 306 by the elastic force of the second spring 303, achieving the effect of stabilizing the position of the sealing gasket 204. Moreover, by virtue of the clamping of the sliding column 304 and the circular groove 306, when the rectangular column 206 moves downward, the rectangular frame 211 cannot move the connecting piece 214, but only moves the sliding block 212, so that the sealing gasket 204 is still pressed against the tunnel wall, and the position does not change.

[0047] In an optional embodiment, the drainage mechanism 3 includes two baffles 309 arranged inside the fixed frame 202 and four fixed plates 313. The surface of the fixed plate 313 is provided with an arc-shaped groove 316 and a connecting groove 317. The inner wall of the connecting groove 317 is slidingly connected with a circular column 312. One end of the circular column 312 is fixedly connected with a connecting plate 311. The surface of the fixed plate 313 is fixedly connected with a pressing piece 318.

[0048] A plurality of circular arc grooves are arranged on the circular arc surface of the sealing gasket 204, which plays a role in guiding the water flow, so that the water flow can flow to the leakage hole 2041.

[0049] The inner wall of the fixed frame 202 is rotatably connected with two first rotating rods 307 and two second rotating rods 314. The circular arc surface of the two first rotating rods 307 is fixedly connected with a fixed block 308. The two baffles 309 are fixedly connected with the two fixed blocks 308. The circular arc surface of the first rotating rod 307 is sleeved with a first torsional spring 310. The two ends of the first torsional spring 310 are fixedly connected with the first rotating rod 307 and the inner wall of the fixed frame 202, respectively. The four fixed plates 313 are arranged in two groups. The two groups of fixed plates 313 are fixedly connected with the circular arc surfaces of the two second rotating rods 314, respectively.

[0050] The two sides of the rectangular column 206 are fixedly connected with a fixed piece 319. The bottom ends of the four connecting plates 311 are fixedly connected with the four fixed pieces 319, respectively. The bottom ends of the four connecting plates 311 are slidingly penetrated through the fixed frame 202 and the base frame 1. The arc-shaped groove 316 and the connecting groove 317 are in communication. The inner bottom wall of the fixed frame 202 and the surface of the base frame 1 are both provided with holes for the connecting plate 311 to pass through. The width of the hole at the connection between the fixed frame 202 and the connecting plate 311 is adapted to the width of the connecting plate 311. When the fixed frame 202 is lifted upward, the fixed frame 202 is not easy to be tilted under the limitation of the connecting plate 311. However, the overall size of the hole at the connection between the fixed frame 202 and the connecting plate 311 is greater than the length of the connecting plate 311, so that the fixed frame 202 can not be blocked by the connecting plate 311 when the two sides of the fixed frame 202 are expanded.

[0051] It should be noted that at the time of drainage, at this time the cylinder 312 has been inside the arc-shaped groove 316, the rectangular column 206 moves downward, the cylinder 312 will slide downward inside the arc-shaped groove 316, the fixed plate 313 swings, driving the extrusion piece 318 to extrude the baffle 309, so that the baffle 309 rotates, causing the recess hole 205 to be notched, which is beneficial to drainage, that is, the upward movement of the rectangular column 206 expands the sealing gasket 204 to extrude the sealing gasket 204 to the tunnel wall to achieve the effect of waterproofing, and the downward movement of the rectangular column 206 achieves the effect of draining the water flow between the sealing gasket 204 and the tunnel wall;

[0052] In the initial state, the cylinder 312 is located in the connecting groove 317, and when the sealing gasket 204 is extruded to the tunnel wall, the electric push rod 201 is needed to push the rectangular column 206 upward, when the rectangular column 206 moves upward, the connecting plate 311 moves upward together, and the fixed frame 202 also moves upward together, and at the same time of upward movement, the fixed frame 202 is extruded by the pressing plate 215, so that the fixed frame 202 expands on both sides, since the fixed plate 313 is located inside the fixed frame 202, when the fixed frame 202 expands outward, it will drive the fixed plate 313 to move, under the action of the connecting groove 317, the fixed plate 313 can move and is not blocked by the connecting plate 311, so that the cylinder 312 will finally be located inside the arc-shaped groove 316, and the inner wall size of the connecting groove 317 is greater than the size of the cylinder 312. The connecting groove 317 plays a role in limiting the position of the cylinder 312 in the initial state, so that the fixed plate 313 can smoothly move and the cylinder 312 can enter the arc-shaped groove 316 when the fixed frame 202 expands on both sides due to the upward movement of the rectangular column 206 in the initial state.

[0053] Since the first torsional spring 310 is arranged on the first rotating rod 307, under the limitation of the first torsional spring 310, the baffle 309 is tightly blocked at the recess hole 205, and the baffle 309 is made of rubber material and has a waterproof effect, so that water at the recess hole 205 cannot directly penetrate into the baffle 309.

[0054] In an optional embodiment, the inside of the base frame 1 is provided with a drain pipe 315, both ends of the drain pipe 315 penetrate through the top and the side wall of the base frame 1, the top end of the drain pipe 315 is in communication with the bottom of the fixed frame 202, and the drain pipe 315 is an elastic hose;

[0055] It should be noted that the inner bottom wall of the fixed frame 202 is inclined to the drain pipe 315, so that the water flow in the fixed frame 202 flows to the drain pipe 315 and is drained away through the drain pipe 315.

[0056] The working principle of the present application is as follows: when a leakage point appears in the tunnel, the staff moves the entire device into the tunnel, the two base frames 1 are located at the edge of the tunnel, and the waterproof effect is achieved by extruding the sealing gasket 204 onto the tunnel wall, the electric push rod 201 is started, the rectangular column 206 is driven to move upwards, the rectangular column 206 extrudes the fixed frame 202 through the rectangular hole 207, the fixed frame 202 moves upwards, and the rectangular column 206 moves to extrude the driving block 208, since the surfaces of the driving block 208 and the upper sliding groove of the rectangular column 206 are both inclined surfaces, the driving block 208 will move to the right side at this time, since the cross-sectional shape of the sliding block 212 is convex, the sliding block 212 will not slide inside the rectangular frame 211, the rectangular frame 211 will slide along the inner wall of the square frame 210, and under the connection of the connecting piece 214, the pressing plate 215 moves to the right, the pressing plate 215 will extrude the fixed frame 202 through the limiting hole 216, that is, when the rectangular column 206 moves upwards, the fixed frame 202 moves upwards and expands towards the tunnel wall, until the sealing gasket 204 on the fixed frame 202 is extruded onto the tunnel wall, so that when water seepage occurs, the water flow is blocked by the sealing gasket 204, achieving the effect of waterproofing, while the connecting piece 214 drives the pressing plate 215 to move, the cylindrical body 302 will move synchronously with the connecting piece 214, at this time the sliding column 304 is extruded on the inner wall of the square hole 305, and the second spring 303 is in a compressed state, until the sealing gasket 204 is extruded onto the tunnel wall, at this time the sliding column 304 will coincide with the position of the circular groove 306, at this time the second spring 303 will rebound, the sliding column 304 will slide into the circular groove 306, achieving the effect of stabilizing the position of the pressing plate 215, that is, stabilizing the position of the sealing gasket 204, in the process of moving the rectangular column 206 upwards, the connecting plate 311 moves upwards together, the fixed frame 202 also moves upwards together, the cylindrical body 312 is located in the connecting groove 317 at this time, and as the pressing plate 215 extrudes the fixed frame 202, the fixed frame 202 expands on both sides, since the fixed plate 313 is located inside the fixed frame 202, the fixed frame 202 expands outward, which drives the fixed plate 313 to move, under the action of the connecting groove 317, the fixed plate 313 can move and is not blocked by the connecting plate 311, so that the cylindrical body 312 finally locates in the arc-shaped groove 316;

[0057] When it is needed to discharge the water between the sealing gasket 204 and the tunnel wall, the rectangular column 206 is moved downward by starting the electric push rod 201, at this time the driving block 208 is moved to the direction close to the sliding block 212, since the sliding column 304 is located in the circular groove 306 at this time, the connecting piece 214 cannot be moved, at this time the sliding block 212 will be moved to the direction close to the first spring 213, the first spring 213 is in the compressed state, that is, the sealing gasket 204 will still be pressed on the tunnel wall, the position does not change, at this time, the cylinder 312 slides downward along the inside of the arc-shaped groove 316, the fixed plate 313 will rotate, driving the pressing piece 318 to press the baffle 309, the baffle 309 rotates, the first torsional spring 310 is in the torsional state, so that the recess 205 is provided with a gap, when the water flow between the sealing gasket 204 and the tunnel wall is more, the water flow will flow downward along the gap between the sealing gasket 204 and the tunnel wall, when it flows to the leakage hole 2041, since the leakage hole 2041 is provided with a recess, the water flow will enter the leakage hole 2041 by means of the recess, so as to flow into the fixed frame 202 from the gap opened by the rotation of the baffle 309, since the inner bottom wall of the fixed frame 202 is inclined to the drain pipe 315, the water flow in the fixed frame 202 will flow to the drain pipe 315, and is discharged through the drain pipe 315, when not in use, the rectangular column 206 is moved upward, the cylinder 312 slides upward along the inside of the arc-shaped groove 316, the fixed plate 313 will rotate in the opposite direction, the pressing piece 318 is separated from the pressing of the baffle 309, the first torsional spring 310 will rebound, and the baffle 309 will be blocked at the recess 205 again, blocking the water flow.

[0058] Although the embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application is defined by the appended claims and their equivalents.
