Description

Technical Field

[0001] This utility model relates to the field of tunnel monitoring technology, and in particular to a subway structure leakage monitoring device. Background Technology

[0002] As a vital mode of transportation in modern cities, the safe, efficient, and comfortable operation of subways is crucial for the daily commutes of urban residents. However, during long-term operation, subway structures inevitably experience structural leakage problems due to various factors such as geological conditions, construction quality, material aging, and the external environment. Structural leakage not only affects the normal operation of the subway and creates safety hazards, but may also threaten the structural safety of subway stations and tunnels, and even lead to more serious engineering accidents. While existing subway structural leakage monitoring devices are generally sufficient for daily use, some shortcomings still require improvement.

[0003] Most commercially available subway structural leakage monitoring devices typically use radar for monitoring, and the radar is bolted to the top of the tunnel. However, in actual use, due to the limited space inside the subway tunnel, especially when the radar is installed on the tunnel wall or ceiling, operators often face significant space constraints. Furthermore, bolted installation and removal require specific tools such as wrenches and screwdrivers, which become extremely inconvenient or even impossible to use effectively when working at heights in the subway tunnel, greatly increasing the difficulty of disassembly. Therefore, we propose a subway structural leakage monitoring device to solve these problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A subway structure leakage monitoring device includes a tunnel, a track on the inner wall of the tunnel, platforms on both sides of the track, a slide rail on the inner wall above the track, a sliding frame sliding within the slide rail, rollers rotating within the sliding frame, the rollers engaging with the slide rail, a motor at the front end of the rollers, two sets of grooves on the left side surface of the slide rail, sliders sliding within the grooves, a radar at the bottom of the sliders, guide grooves on the front and rear surfaces of the sliders, sliding discs sliding within the guide grooves, a rod at the bottom of each sliding disc, a first spring wound around the surface of each rod, limiting rings on the front and rear surfaces of the sliding frame, the sliding discs and limiting rings being slidably connected, and a controller on the inner wall of the tunnel, the controller being electrically connected to the motor via wires.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] I. This utility model uses a sliding frame installed on the inner wall of the tunnel to allow a motor to drive rollers to rotate within the sliding frame, which in turn drives the radar to slide on the slide rail. The radar then slides in the slide groove via a slider, and the restoring force of the first spring pushes the sliding disc through the limiting ring.

[0028] Figures 1 to 5 As shown, this embodiment provides a subway structure leakage monitoring device, including a tunnel 1, a track 2 on the inner wall of the tunnel 1, platforms 3 on both sides of the track 2, a slide rail 4 on the inner wall of the tunnel 1 above the track 2, a sliding frame 5 sliding inside the slide rail 4, a roller 6 rotating inside the sliding frame 5, the roller 6 being in contact with the slide rail 4, a motor 7 at the front end of the roller 6, two sets of sliding grooves 9 on the left side surface of the slide rail 4, a slider 10 sliding inside the sliding grooves 9, a radar 8 at the bottom of the slider 10, guide grooves 11 on the front and rear surfaces of the slider 10, sliding discs 12 sliding inside the guide grooves 11, a rod 13 at the bottom of the sliding discs 12, a first spring 14 wound around the surface of the rod 13, a limiting ring 15 on the front and rear surfaces of the sliding frame 5, the sliding discs 12 and the limiting rings 15 being slidably connected, a controller 28 on the inner wall of the tunnel 1, and the controller 28 being electrically connected to the motor 7 via wires.

[0029] By setting a sliding frame 5 on the inner wall of tunnel 1, the motor 7 drives the roller 6 to rotate in the sliding frame 5, and drives the radar 8 to slide on the slide rail 4. Then, the slider 10 slides in the slide groove 9, and the restoring force of the first spring 14 pushes the sliding plate 12 through the limiting ring 15, which makes it easier for workers to disassemble and assemble the radar 8, so as to reduce the difficulty of disassembling and assembling the radar 8. At the same time, workers can also install and disassemble the radar 8 at the top of the subway tunnel.

[0030] In other embodiments, a guide rail 16 is provided on the surface of the slider 10 around the radar 8, a brake ring 17 is rotatably mounted inside the guide rail 16, a rack 18 is provided on the outer wall of the brake ring 17, a fixed seat 19 is provided on the left outer wall of the slider 10, a gear 20 is rotatably mounted inside the fixed seat 19, a brake disc 21 is provided on the bottom surface of the gear 20, a threaded block 22 is threadedly connected to the brake disc 21, a fixed plate 23 is provided on the surface of the rack 18 on the right side of the radar 8, a slide rod 24 slides inside the fixed plate 23, a cleaner 25 is provided on the left side of the slide rod 24, a second spring 26 is wound around the surface of the slide rod 24 between the cleaner 25 and the fixed plate 23, a slide plate 27 is provided on the right side of the cleaner 25, and the slide plate 27 slides inside the fixed plate 23;

[0031] The restoring force of the second spring 26 drives the slide bar 24 to return to its original position within the fixed plate 23 and makes the cleaner 25 fit against the outer wall of the radar 8. Then, the brake disc 21 drives the gear 20 to rotate within the fixed seat 19, and the gear 20 drives the brake ring 17 to rotate within the guide rail 16 via the rack 18. This achieves the purpose of cleaning the dust on the surface of the radar 8, preventing the accumulation of dust on the surface of the radar 8, which would affect the monitoring and sensing effects of the radar 8.

[0032] like Figure 5 As shown, one end of the first spring 14 is welded to the surface of the sliding disk 12, and the other end of the first spring 14 is welded to the inner wall of the guide groove 11.

[0033] This design allows for the fixation of both ends of the first spring 14, preventing the spring 14 from repeatedly impacting the guide groove 11 or the sliding disk 12, thus avoiding noise pollution.

[0034] like Figure 5 As shown, the outer end of the insertion rod 13 is provided with a handle, and the handle is designed in a cylindrical shape;

[0035] This design prevents workers from slipping their hands when pulling the plug rod 13, thus avoiding the need to repeatedly pull the plug rod 13.

[0036] like Figure 4 As shown, the slide plate 27 has a rectangular design, and the fixing plate 23 has through holes that are adapted to the slide plate 27.

[0037] This design allows the slide plate 27 to fully fit against multiple surfaces of the fixed plate 23, and guides the sliding rod 24 to slide. This prevents the slide plate 27 from wobbling when the second spring 26 drives the sliding rod 24 to slide within the fixed plate 23, which would prevent the cleaner 25 from fully fitting against the radar 8 and thus affect the cleaning effect of the cleaner 25.

[0038] like Figure 4 As shown, the surface of the cleaner 25 facing the radar 8 is provided with Velcro, and a cleaning cloth is provided on the side of the Velcro facing the radar 8. Both the cleaner 25 and the cleaning cloth are designed in an arc shape, and the curvature of the cleaner 25 and the radar 8 are equal.

[0039] This design makes it easier for staff to replace the cleaning cloth, preventing dust from accumulating on the surface of the cloth and thus affecting its cleaning effect.

[0040] like Figure 4 As shown, the threaded block 22 has a pentagonal design, and a soft pad is provided on the side surface of the threaded block 22 facing the fixed seat 19.

[0041] This design increases the friction between the operator's hand and the threaded block 22 when using the threaded block 22, preventing slippage. At the same time, the soft pad on the outer wall of the threaded block 22 can prevent friction damage to the fixed seat 19.

[0042] This utility model provides a subway structure leakage monitoring device, the specific working principle of which is as follows:

[0043] In use, the device first activates the motor 7 via the controller 28, causing the roller 6 to rotate. This causes the roller 6 to slide the sliding frame 5 along the slide rail 4 until it reaches a position accessible to the operator. Then, by pulling the insertion rod 13, the sliding plate 12 slides into the guide groove 11. Simultaneously, the sliding plate 12 continuously presses against the first spring 14 against the inner wall of the guide groove 11 until it is fully inserted. At this point, the slider 10 slides into the slide groove 9, allowing the radar 8 to... Fixed on the sliding frame 5, the slider 10 drives the sliding disk 12 to align with the limiting ring 15. Then, by releasing the insert rod 13, the restoring force of the first spring 14 pushes the sliding disk 12 to slide in the guide groove 11 and make the sliding disk 12 pass through the limiting ring 15, thereby achieving the purpose of installing the radar 8. When it is necessary to disassemble the radar 8, the insert rod 13 drives the sliding disk 12 to slide from the limiting ring 15 into the guide groove 11, and then the slider 10 slides out from the sliding groove 9, thereby achieving the purpose of disassembling the radar 8.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
