Description

Technical Field

[0001] The present invention relates to the technical field of water seepage detection for subway tunnel construction segments, and in particular to a device for detecting water seepage for subway tunnel construction segments. Background Art

[0002] Subway tunnel construction is a complex and technically demanding project, typically employing either shield or open-cut methods. The shield method uses a tunnel boring machine to dig a tunnel underground, effectively controlling ground subsidence and minimizing environmental impact, making it suitable for use in busy urban areas. The open-cut method involves excavating a foundation pit before constructing the tunnel structure. It is often used in areas with good geological conditions and open ground, and requires segment installation during construction.

[0003] Patent application publication number CN114509375B discloses a device for detecting water seepage in subway tunnel construction segments, comprising a placement bucket containing multiple support assemblies. One side of the placement bucket is rotatably connected to a rotating rod, the outer circle of which is rotatably connected to a circular shell. The outer circle of the circular shell is fixedly connected to two connecting tubes, the interiors of the two connecting tubes being connected to the circular shell. One end of each connecting tube is rotatably connected to a roller, the sidewall of the inner cavity of the circular shell being rotatably connected to a rotating wheel, a red detection tape is connected between the rotating wheel and the roller, and the outer side of the red detection tape is provided with a layer of transparent ink.

[0004] The above patent sets a roller and a red detection belt. The transparent ink on the surface of the red detection belt turns transparent red when it is stained with water and leaks out, making the red detection belt appear obviously red, thereby determining the leaking area. The roller can roll on the inner wall of the pipe segment and thus detect most areas of the inner wall of the pipe segment. However, the above patent cannot detect multiple positions, and the positions are different and the distances from the pipeline are also different, so effective contact cannot be made, resulting in ineffective detection. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a water seepage detection device for subway tunnel construction segments to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A water seepage detection device for subway tunnel construction segments, comprising a frame, a motorized moving component fixedly connected to the bottom of the frame, a motorized steering component fixedly connected to the bottom of the frame, and an auxiliary mechanism fixedly connected to the top of the frame. The frame is provided with a remotely controlled chip, and the motorized moving component can drive the movement of the entire component when powered on, and the motorized steering component can change the direction of movement of the frame when powered on.

[0007] frame

[0008] Position: It constitutes the main structure of the device and is located in the center of the entire device;

[0009] Function: Carrying electric moving parts, steering parts and auxiliary mechanisms;

[0010] Effect: Realize the integrated layout of each functional module through integrated design;

[0011] The auxiliary mechanism includes:

[0012] The first mechanical component is fixedly connected to the top of the frame and adopts a combination design of a spring and a threaded adjustment assembly. The tension of the spring on the connecting rod can be precisely adjusted by rotating the bolt. This allows the detection mechanism to closely fit the surface of the segment at different distances and dynamically adjust the contact pressure according to the concave and convex features of the segment, avoiding missed detections due to poor contact. It is particularly suitable for detecting irregular surfaces at the joints of tunnel segments;

[0013] Electric moving parts

[0014] Position: fixed on the frame;

[0015] Function: The driving device moves along the surface of the segment;

[0016] Effect: It adopts a wheeled structure and cooperates with the remote control chip to achieve autonomous movement;

[0017] a connecting rod, one end of which is rotatably connected to the outer wall of the first mechanical component;

[0018] a second mechanical component, the second mechanical component being rotatably connected to the other end of the connecting rod;

[0019] Electric steering components

[0020] Position: Installed in parallel at the bottom of the frame;

[0021] Function: Control the direction of movement;

[0022] Effect: The travel direction can be precisely adjusted through the universal wheel structure;

[0023] The outer wall of the second mechanical component is fixedly connected to the detection mechanism. The coordinated cooperation of the electric moving component and the steering component enables the device to move autonomously along the surface of the segment and adjust its direction of travel, covering detection areas at different longitudinal positions. At the same time, the first mechanical component in the auxiliary mechanism drives the connecting rod to rise and fall, and the second mechanical component drives the detection mechanism to rotate, realizing the detection mechanism's multi-angle posture adjustment in the horizontal and vertical directions, effectively solving the problem that traditional devices cannot adapt to the curved surface structure of the segment and multi-position detection.

[0024] Auxiliary institutions

[0025] Position: fixed on the top of the frame;

[0026] Function: Support and adjust the spatial posture of the detection mechanism;

[0027] Effect:

[0028] The first mechanical component: drives the connecting rod to rise and fall vertically;

[0029] Connecting rod: articulated structure enables multi-directional movement;

[0030] The second mechanical component: drives the detection mechanism to rotate horizontally;

[0031] Screw seat and bolt: adjust the spring preload through thread fit;

[0032] Spring: Dynamically compensates for the unevenness of the segment surface and maintains constant contact pressure.

[0033] Preferably, the top of the frame is fixedly connected to a screw seat, and the inner wall of the screw seat is threadedly connected to a bolt. When the first mechanical component is powered on and started, it will drive the turning of the connecting rod. The lifting and lowering of the connecting rod is controlled by the first mechanical component to adapt to different heights. The second mechanical component can be rotated when powered on, thereby controlling the detection mechanism to contact the pipe segment at different angles. By rotating the bolt, the pulling force of the spring on the connecting rod can be adjusted. The threaded connection between the bolt and the screw seat limits the position of the bolt, so that the connecting rod contacts the pipe segment with greater force, thereby increasing the contact force between the detection mechanism and the pipe segment.

[0034] Preferably, the bolt is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to a connecting rod. The detection mechanism utilizes the deformation characteristics of the sponge material to fully fit the gap between the pipe segments, and realizes automatic detection of water seepage through the principle of water absorption and conductivity (the circuit is disconnected when there is no water, and the alarm is triggered when there is water). Combined with the diversion structure of the collection box, it ensures that even trace water seepage can be effectively captured, and the water level change in the pipeline is directly converted into an electrical signal, thereby improving the detection response speed and accuracy.

[0035] Testing agency

[0049] Air flow tube: adjustable angle nozzle to achieve fixed-point drying;

[0050] Electric slider and slide rail: drives the air flow tube to move back and forth to dry the sponge evenly.

[0051] Preferably, the detection mechanism includes a collection box, which is fixedly connected to the top of the second mechanical component, a sponge block is fixedly connected to the top of the collection box, a pipe is fixedly connected to the bottom of the collection box, and a power block is fixedly connected to the outer wall of the pipe. The power block is two metal electrodes, which are respectively fixed to the upper and lower ends of the inner wall of the pipe. The electrodes are connected to the alarm circuit. When the water level rises to contact the upper electrode, the circuit is turned on to trigger the alarm. The inner wall of the pipe is provided with power blocks distributed up and down.

[0052] Preferably, there are two power blocks, which are used to connect components that require power.

[0053] Preferably, the sponge block is made of sponge material, and the lower half of the sponge block is located in the collection box.

[0054] Preferably, the outer wall of the collection box is fixedly connected with a processing component, and the height of the sponge block is higher than the collection box, so when the sponge block contacts the pipe segment, it will deform according to the shape of the pipe segment, and then effectively fit the gap of the pipe segment. The sponge block absorbs the seeping water, and then the water is deposited in the collection box under gravity. The water in the collection box is deposited in the pipe. The two ends of the power block are connected to the components that remind when power is turned on. When there is no water in the pipe, it is a power-off state. When there is water in the pipe, the two power blocks form a power-on state. The device moves along the pipe segment through the dual-drive system at the bottom of the frame. The multi-degree-of-freedom adjustment of the auxiliary mechanism makes the sponge block fit the curved surface tightly. The seepage water is adsorbed to the collection box through the sponge. The water level triggers the power block to alarm. The processing component automatically drains the accumulated water after the detection cycle, and drives the air flow pipe to blow at multiple positions through the slide rail to ensure the continuous operation reliability of the device.

[0055] Preferably, the processing component includes a fan, the outer wall of the fan is fixedly connected to the outer wall of the collection box, the outer wall of the fan is fixedly connected to one end of the zigzag tube, the other end of the zigzag tube is fixedly connected to the airflow tube, the outer wall of the collection box is fixedly connected to a slide rail, after each detection, the fan is powered on and started, first the electric slider is powered on and started and moves on the slide rail, driving the airflow tube away from the sponge block, the fan is started at this time, and then the water in the pipeline is sucked, and then discharged to other positions, after a period of suction, the electric slider is located on the slide rail and moves to the position of the sponge block, thereby driving the airflow tube to blow out air onto the sponge block, the electric slider cyclically moves at the position of the sponge block for a period of time, during this period, the airflow blown out by the airflow tube cleans the moisture on the sponge block, accelerates the evaporation of moisture in the sponge block, and facilitates the detection mechanism to detect water seepage again, the outer wall of the slide rail is slidably connected to the electric slider, and the outer wall of the electric slider is fixedly connected to the outer wall of the airflow tube.

[0056] Preferably, the outer wall of the fan is fixedly connected to the outer wall of the collection box through a bracket. The processing component cooperates with the fan and the movable airflow pipe to first drain the water accumulated in the pipe and then blow the sponge block in a direction. The reciprocating motion driven by the slide rail allows the airflow to act evenly on the inside of the sponge, which not only achieves rapid removal of residual water after detection, but also avoids manual intervention, ensuring that the device maintains stable water absorption performance during continuous operation. It is particularly suitable for high-frequency detection scenarios in long-distance tunnels.

[0057] Preferably, the inner wall of the frame is fixedly connected with a rocking mechanism, and the rocking mechanism includes a rocking track, the rocking track is fixedly connected to the inner wall of the frame, the outer wall of the rocking track is slidably connected with a rocking slider, the outer wall of the rocking slider is fixedly connected with a limiting ring, the outer wall of the limiting ring is plugged with a connecting ring, the bottom of the connecting ring is plugged with a rocking block, and the rocking slider is driven by a motor to achieve reciprocating motion.

[0058] The present invention provides a device for detecting water seepage in subway tunnel construction segments. It has the following beneficial effects:

[0059] 1. This subway tunnel construction segment water seepage detection device, through the coordinated cooperation of electric moving parts and steering parts, enables the device to move autonomously along the segment surface and adjust its direction of travel, covering detection areas at different longitudinal positions. At the same time, the first mechanical component in the auxiliary mechanism drives the connecting rod to rise and fall, and the second mechanical component drives the detection mechanism to rotate, realizing multi-angle posture adjustment of the detection mechanism in the horizontal and vertical directions, effectively solving the problem that traditional devices cannot adapt to the curved surface structure of the segment and multi-position detection.

[0060] 2. This subway tunnel construction segment water seepage detection device adopts a combined design of spring and threaded adjustment components. The tension of the spring on the connecting rod can be precisely adjusted by rotating the bolt, so that the detection mechanism can not only closely fit the surface of the segment at different distances, but also dynamically adjust the contact pressure according to the concave and convex features of the segment, avoiding missed detection due to poor contact. It is particularly suitable for detecting irregular surfaces at the joints of tunnel segments.

[0061] 3. This subway tunnel construction segment water seepage detection device uses a detection mechanism that utilizes the deformation characteristics of sponge materials to fully fit the gaps in the segments, and realizes automatic sensing of water seepage through the principle of water absorption and conductivity (the circuit is disconnected when there is no water, and the power is turned on to trigger the alarm when there is water). Combined with the diversion structure of the collection box, it ensures that even trace water seepage can be effectively captured, and the water level changes in the pipeline are directly converted into electrical signals, which improves the detection response speed and accuracy.

[0062] 4. This device for detecting water seepage in subway tunnel construction segments uses a processing component, a fan, and a movable airflow tube to first drain the water from the pipe and then blow the sponge in a directionally clean manner. The reciprocating motion driven by the slide rail allows the airflow to evenly act on the inside of the sponge, which not only achieves rapid removal of residual moisture after detection but also avoids manual intervention, ensuring that the device maintains stable water absorption performance during continuous operation. It is particularly suitable for high-frequency detection scenarios in long-distance tunnels.

[0063] 5. The water seepage detection device for the subway tunnel construction pipe segment moves back and forth on the shaking track through the shaking slider, which will drive the limit ring to move along.

[0074] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0075] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0076] For example 1, please refer to Figure 1-5 The present invention provides a technical solution: a device for detecting water seepage in a subway tunnel construction segment, comprising a frame 1, a remotely controlled chip being provided on the frame 1, an electric moving component 2 being powered on and activated to drive the entire component to move, the electric moving component 2 being fixedly connected to the bottom of the frame 1, an electric steering component 3 being fixedly connected to the bottom of the frame 1, and an auxiliary mechanism 4 being fixedly connected to the top of the frame 1;

[0077] The frame 1 is equipped with a remote control chip. When the electric moving component 2 is powered on, it can drive the movement of the entire component. When the first mechanical component 41 is powered on, it can drive the steering of the connecting rod 42. The first mechanical component 41 controls the raising and lowering of the connecting rod 42 to adapt to different heights. When the electric steering component 3 is powered on, it can change the direction of movement of the frame 1.

[0078] The auxiliary mechanism 4 includes:

[0079] A first mechanical component 41 is fixedly connected to the top of the frame 1;

[0080] a connecting rod 42 , one end of which is rotatably connected to the outer wall of the first mechanical component 41 ;

[0081] A second mechanical component 43, the second mechanical component 43 is rotatably connected to the other end of the connecting rod 42;

[0082] The outer wall of the second mechanical component 43 is fixedly connected with the detection mechanism 5 .

[0083] A screw seat 44 is fixedly connected to the top of the frame 1 , and a bolt 45 is threadedly connected to the inner wall of the screw seat 44 .

[0084] One end of a spring 46 is fixedly connected to the bolt 45 , and the other end of the spring 46 is fixedly connected to the connecting rod 42 .

[0085] When the first mechanical component 41 is powered on, it drives the connecting rod 42 to turn. The first mechanical component 41 controls the raising and lowering of the connecting rod 42 to adapt to different heights. When the second mechanical component 43 is powered on, it can rotate, thereby controlling the detection mechanism 5 to contact the pipe segment at different angles. By turning the bolt 45, the pulling force of the spring 46 on the connecting rod 42 can be adjusted. The threaded connection between the bolt 45 and the screw seat 44 restricts the position of the bolt 45, so that the connecting rod 42 contacts the pipe segment with greater force, thereby increasing the contact force between the detection mechanism 5 and the pipe segment.

[0086] The sponge block 52 is embedded with a conductive fiber mesh. When the sponge absorbs trace amounts of water, the moisture forms a conductive path between the conductive fibers. Even if the sponge is not saturated, the change in resistance can still trigger the circuit to conduct. The threshold can be set to the trace humidity value. Furthermore, a capillary guide groove is provided at the bottom of the collection box 51. Through capillary action, it guides trace water to the pipe 53, ensuring that the trace water accumulates to the detection threshold.

[0087] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0088] The detection mechanism 5 includes a collection box 51, which is fixedly connected to the top of the second mechanical component 43. A sponge block 52 is fixedly connected to the top of the collection box 51, and a pipe 53 is fixedly connected to the bottom of the collection box 51. The outer wall of the pipe 53 is fixedly connected to a power block 54. The power block 54 is two metal electrodes, which are respectively fixed to the upper and lower ends of the inner wall of the pipe 53. The electrodes are connected to the alarm circuit. When the water level rises to contact the upper electrode, the circuit is turned on and the alarm is triggered. The inner wall of the pipe 53 is provided with power blocks 54 distributed up and down.

[0089] There are two power blocks 54 , which are used to connect components that require power.

[0090] The sponge block 52 is made of sponge material, and the lower half of the sponge block 52 is located in the collection box 51 .

[0091] A processing assembly 55 is fixedly connected to the outer wall of the collection box 51 .

[0092] The processing component 55 includes a fan 552, the outer wall of the fan 552 is fixedly connected to the outer wall of the collecting box 51, the outer wall of the fan 552 is fixedly connected to one end of the zigzag tube 553, the other end of the zigzag tube 553 is fixedly connected to the airflow tube 554, the outer wall of the collecting box 51 is fixedly connected to the slide rail 556, the outer wall of the slide rail 556 is slidably connected to the electric slider 555, and the outer wall of the electric slider 555 is fixedly connected to the outer wall of the airflow tube 554.

[0093] The outer wall of the fan 552 is fixedly connected to the outer wall of the collection box 51 through the bracket 551;

[0094] The height of the sponge block 52 is higher than the collection box 51. Therefore, when the sponge block 52 contacts the pipe segment, it will deform according to the shape of the pipe segment, and then effectively fit the gap between the pipe segments. The sponge block 52 absorbs the seeping water, and then the water is deposited into the collection box 51 under gravity. The water in the collection box 51 is deposited into the pipe 53. The two ends of the power block 54 are connected to the components that will be powered on. When there is no water in the pipe 53, the power is off. When there is water in the pipe 53, the two power blocks 54 form a power-on state.

[0095] After each detection, the fan 552 is powered on and started. First, the electric slider 555 is powered on and started to move on the slide rail 556, driving the air flow tube 554 away from the sponge block 52. The fan 552 is started at this time, and then sucks the water in the pipe 53 and then discharges it to other positions. After sucking for a period of time, the electric slider 555 is located on the slide rail 556 and moves to the position of the sponge block 52, thereby driving the air flow tube 554 to blow air onto the sponge block 52. The electric slider 555 circulates and moves to the position of the sponge block 52 for a period of time. During this period, the air flow blown out by the air flow tube 554 cleans the water on the sponge block 52, accelerates the evaporation of water in the sponge block 52, and facilitates the detection mechanism 5 to detect water seepage again;

[0096] When the amount of water seepage is small, the sponge block 52 slowly guides the water into the collection box 51 through the capillary diversion groove. The power block 54, which is a water level sensor, is set in the pipe 53. When the water level reaches the set height, the two power blocks 54 conduct electricity through the water body to trigger the alarm. If the amount of water seepage is extremely small, the device will periodically move to detect the same area and accumulate the water seepage to the detectable threshold.

[0097] The zigzag tube 553 is made of elastic material and can be deformed by the pull of the electric slider 555;

[0117] The screw seat 44 and the bolt 45: adjust the pre-tightening force of the spring 46 through the threaded fit;

[0118] Spring 46: dynamically compensates for the unevenness of the segment surface and maintains a constant contact pressure;

[0119] Testing agency 5

[0120] Position: connected to the end of the second mechanical component 43;

[0121] Function: core component of water seepage detection;

[0122] Effect:

[0134] The electric slider 555 and the slide rail 556 drive the air flow tube 554 to move back and forth to dry the sponge evenly.

[0135] How it works together:

[0136] The device moves along the pipe segment via a dual-drive system at the bottom of the frame 1. The multi-degree-of-freedom adjustment of the auxiliary mechanism 4 allows the sponge block 52 to fit tightly to the curved surface. Seepage water is absorbed by the sponge into the collection box 51. The water level triggers the power block 54 to alarm. The processing component 55 automatically pumps out the accumulated water after the detection cycle, and the slide rail 556 drives the airflow pipe 554 to purge at multiple positions, ensuring the continuous operation and reliability of the device.

[0137] For example three, please refer to Figure 1-9 Based on the first and second embodiments, the present invention provides a technical solution:

An electric moving part 2 is provided at the bottom of the frame 1, which allows the device to produce fine displacement adjustment when rocking. The rocking slider 62 is driven by a motor to achieve reciprocating motion;

[0139] The rocking slider 62 is powered on and starts to move back and forth on the rocking track 61, which will drive the limit ring 63 to move along. The connecting ring 64 is respectively installed on the limit ring 63 and the rocking block 65. When the rocking slider 62 circulates, it will drive the movement of the rocking block 65, and then the rocking block 65 will rock and drive the whole rocking, thereby increasing the range of water seepage detection. The rocking slider 62 makes reciprocating linear motion along the rocking track 61, and the linear motion is converted into the swing of the rocking block 65 through the hinge of the limit ring 63 and the connecting ring 64. Under the periodic swing of the rocking block 65, the whole device produces slight vibration, which prompts the detection mechanism 5 to dynamically adjust the contact surface with the pipe segment to cover a larger detection area.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
