[0025] The upper end of the cover body 2 is in an arc structure, the upper and lower ends of the cover body 2 are both in an open structure, a rubber bag 21 is fixedly connected in the cover body 2, the bottom of the rubber bag 21 is fixedly connected with a drain pipe 22, and the lower end of the drain pipe 22 is fixedly connected with the upper end of the second hose 3.

[0026] The main shaft of the driving motor 14 of the mobile vehicle 1 is used as a rotating reference, so that the hydraulic telescopic arm 15 can rotate around the central axis of the tunnel to a suitable position, the hydraulic telescopic arm 15 pushes and extends through a hydraulic rod, the cover body 2 is covered in the water seepage area, so that the seepage water can be collected in the rubber bag 21 in the cover body 2 and discharged through the drain pipe 22, the second hose 3 and the flowmeter 12, the seepage water can be collected, and the inconvenience of flow measurement caused by insufficient seepage flow and multiple leakage points is overcome.

[0027] The upper end of the drain pipe 22 is fixedly connected with a filter screen 6, and the bottom of the drain pipe 22 is fixedly connected with a counterweight ring, so that the drain pipe 22 can be kept in a vertical state.

[0028] The bottom of the cover body 2 is fixedly connected with two supporting rods 23, and an arc-shaped guide rod 24 is fixedly connected between the two supporting rods 23, the cross section of the arc-shaped guide rod 24 is square, a guide block 25 is slidably connected on the arc-shaped guide rod 24, when the arc-shaped guide rod 24 is high at one end and low at the other end, the guide block 25 can slide to the lowest end under the action of gravity, one side of the guide block 25 is rotatably connected with a supporting shaft 26, and the supporting shaft 26 is fixedly connected with the drain pipe 22.

[0029] This invention utilizes the guide block 25 to slide along the arc-shaped guide rod 24, ensuring that when the cover 2 operates at different heights on the tunnel wall, based on the spatial position of the arc-shaped guide rod 24 and the flexibility of the rubber bag 21, combined with gravity, the upper end of the drainage pipe 22 is always at the lowest relative position of the cover 2. Figure 3 As shown, when the cover 2 is made of Figure 3 When one end becomes higher than the other, the guide block 25 slides to the other end first, eventually reaching the lowest point, and causing the drain pipe 22 to also move to the lowest end. The water collected by the rubber bag 21 can be drained through the drain pipe 22 at the lowest end. This ensures that the rubber bag 21 can drain smoothly at different positions on the inner wall of the tunnel when the cover 2 covers it, preventing the rubber bag 21 from accumulating excessive water and causing it to fall and break.

[0030] The guide block 25 has a mounting hole on one side, and the support shaft 26 is rotatably connected to the mounting hole. The inner wall of the mounting hole is provided with a rubber ring 27. The upper end of the drain pipe 22 is fixedly connected to the conical cover 4 for collecting slag. The edge of the conical cover 4 is fixedly connected to the bottom of the rubber bag 21. The outer side of the upper end of the drain pipe 22 and the conical cover 4 form a slag collection groove 41. When the upper end of the drain pipe 22 sways in the water in the rubber bag 21, it can prevent the upper end of the drain pipe 22 from being blocked. The slag at the upper end of the swinging drain pipe 22 will fall into the slag collection groove 41, avoiding it from falling directly into the rubber bag 21 and causing the rubber bag 21 to fall and break. It also facilitates centralized cleaning later.

[0031] The upper end of the cover 2 is slidably connected to the arc-shaped frame 5. The outer arc surface of the arc-shaped frame 5 is provided with a sealing strip, which plays a role in anti-slip and sealing, and is used to fit the arc-shaped inner wall of the tunnel. The bottom of the arc-shaped frame 5 is fixedly connected to the limiting slider 51. The upper side of the cover 2 is provided with a limiting groove 52. The limiting slider 51 is slidably connected in the limiting groove 52. The inner wall of one end of the limiting slider 51 and the limiting groove 52 is equipped with a return spring 53.

[0032] In this embodiment, the arc surface of the arc frame 5 is based on the rotation axis of the drive motor 14, so that when the cover 2 is driven by the drive motor 14 to swing in both directions at an angle of 5-10 degrees, since the arc of the two is the same, the cover 2 can fit against the compressed arc frame 5 to form a relative sliding, so that the small amount of water and the drain pipe 22 held by the cover 2 can swing, and the upper end of the drain pipe 22 can be shaken in the accumulated water at regular intervals, thereby avoiding the filter screen 6 from being blocked and affecting the water discharge efficiency.

[0033] The upper end of the drain pipe 22 is fixedly connected with a support column 61, the support column 61 is slidingly connected with a guide rod 62, the two ends of the guide rod 62 are fixedly connected with a counterweight cylinder 63 respectively, the guide rod 62 is fixedly connected with a mounting frame 64, the mounting frame 64 is provided with an avoiding groove 65 for avoiding the guide rod 62, and the mounting frame 64 is fixedly connected with a brush plate 66 on one side.

[0034] In the embodiment, when the drain pipe 22 is inclined when the driving motor 14 drives the hydraulic telescopic arm 15 to swing forward and backward periodically, the drain pipe 22 is swung to the vertical state, and the resistance of the rubber ring 27 cannot immediately swing to the vertical state, the guide rod 62 is in a state that one end is high and the other end is low, the guide rod 62 slides to the position low under the influence of gravity, the bristles at the bottom of the brush plate 66 can be brushed on the surface of the filter screen 6, and the partially blocked soil can be clearly removed; since the support column 61 is provided on one side, the brush plate 66 can be turned over when not in use, and the brush plate 66 is convenient to clean; when the cover body 2 is in an inclined posture, the counterweight cylinder 63 at the end of the guide rod 62 can also collide with the inner wall of the cover body 2, the guide rod 62 slides relative to the support column 61, the brush plate 66 is subjected to the relative thrust under the gravity of the drain pipe 22, and the brush plate 66 is more easily pushed to remove the mud block at the upper end of the drain pipe 22, cooperates with the swing and shaking of the drain pipe 22, and thus the drainage can be kept unobstructed.

[0035] The application further discloses a tunnel water gushing monitoring method, which adopts the monitoring device.

[0036] Working principle of the application:

[0037] The moving vehicle 1 walks to a position where water seeps in the tunnel, the hydraulic telescopic arm 15 pushes the telescopic part through the hydraulic rod, covers the cover body 2 in the water seeping area, so that the seepage water can be collected in the rubber bag 21 in the cover body 2 and discharged through the second hose 3 and the flowmeter 12 through the drain pipe 22, so that the seepage water can be collected, and the inconvenience of seepage flow measurement caused by insufficient seepage flow and frequent leakage is overcome.
