Description

Technical Field

[0001] This invention relates to the field of slope monitoring technology, and in particular to a device for monitoring and early warning of slope cracks. Background Technology

[0002] Slope fissures are an important precursor to geological disasters, and their expansion rate and degree of opening directly reflect the slope's instability risk. To achieve early identification and proactive prevention of disasters such as landslides and collapses, monitoring and early warning devices are often deployed in engineering projects to perceive fissure changes in real time and provide risk alerts.

[0003] However, existing slope crack monitoring and early warning devices generally suffer from insufficient anti-interference capabilities. During long-term field operation, these devices are susceptible to non-hazardous environmental factors such as wind vibration, vegetation growth, animal contact, or temperature changes, leading to frequent false alarms. Furthermore, when actual slope crack propagation occurs, some devices fail to reliably trigger warning signals, severely impacting the accuracy of monitoring results and the practicality of the early warning system. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a monitoring and early warning device for slope cracks, which solves the problem of insufficient anti-interference ability of existing slope monitoring and early warning devices.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A monitoring and early warning device for slope cracks includes: an alarm actuator, an alarm triggering mechanism, and a rope assembly;

[0007] The alarm actuator is used to send an alarm signal;

[0008] The alarm triggering mechanism is located at the second end of the slope's deformation direction. The alarm triggering mechanism includes a first conductive component, a second conductive component, a third conductive component, a first elastic reset component, and a second elastic reset component. The first, second, and third conductive components are arranged sequentially along a first direction perpendicular to the slope's deformation direction. The second conductive component is movably disposed. The first, second, and third conductive components are electrically connected to the alarm actuator. The first elastic reset component is located between the first and second conductive components and applies a first elastic force to the second conductive component to separate them. The second elastic reset component is located between the second and third conductive components and applies a second elastic force to the second conductive component to abut against it.

[0009] The pull rope assembly extends along the deformation direction of the slope. The first end of the pull rope assembly is used to connect to the second end of the deformation direction of the slope. The second end of the pull rope assembly is connected to the second conductive component. The pull rope assembly is used to apply a pulling force to the second guide component in a second direction, which is opposite to the first direction. The pulling force is less than the first elastic force and greater than the second elastic force, so that the first conductive component and the third conductive component are separated from the second conductive component respectively.

[0010] When the rope assembly is tightened due to slope deformation, the second conductive component moves with the rope assembly toward the first conductive component, so that the second conductive component comes into contact with the first conductive component and forms an electrical circuit to trigger the alarm actuator.

[0011] When the pull rope assembly breaks due to slope deformation, the tension applied by the pull rope assembly disappears. Under the elastic force of the second elastic reset member, the second conductive component moves towards the third conductive component, causing the second conductive component to come into contact with the third conductive component and form an electrical circuit to trigger the alarm actuator.

[0012] Furthermore, the rope assembly includes an elastic rope and multiple guy wires, which are distributed sequentially at intervals along a direction perpendicular to the slope deformation direction. The first end of each guy wire is connected to the first end of the slope deformation direction, and the second end of each guy wire is connected to the elastic rope. The elastic rope extends along the first direction, with its first end connected to the slope and its second end connected to the second conductive component. The elastic rope is used to transmit the force of the guy wires along a direction perpendicular to the slope deformation direction to the second conductive component, thereby driving the second conductive component to make a corresponding displacement.

[0013] Furthermore, the alarm triggering mechanism also includes a first sliding member, a second sliding member, and a supporting member; the first sliding member is disposed between the second conductive member and the first conductive member, and the second sliding member is disposed between the second conductive member and the third conductive member; the supporting member is used to support the first sliding member and the second sliding member; when the pull rope assembly is tightened due to slope deformation, the second conductive member moves toward the first conductive member and pushes the first sliding member away from the supporting member; when the pull rope assembly breaks due to slope deformation, the second conductive member moves toward the third conductive member and pushes the second sliding member away from the supporting member; after the first sliding member or the second sliding member is detached from the supporting member, it falls down to provide a mechanical alarm indication or trigger an auxiliary alarm signal.

[0014] Furthermore, a monitoring and early warning device for slope cracks also includes a protective substrate, the protective substrate having a receiving space, and the alarm triggering mechanism being disposed in the receiving space.

[0015] Furthermore, the protective substrate is provided with a guide portion, and the elastic rope is slidably threaded through the guide portion to guide the elastic rope to pull the second conductive component in a direction perpendicular to the deformation direction of the slope.

[0016] Furthermore, the protective substrate is a component made of a transparent material.

[0017] Furthermore, an anchor is provided at the end of the guy wire away from the alarm triggering mechanism, the anchor being used to fix the guy wire to the stable area of ​​the slope.

[0018] Furthermore, the rope assembly is provided with a friction resistance mechanism, which is used to apply a preset friction resistance to the movement of the rope assembly in order to suppress disturbances caused by non-slope deformation.

[0019] Furthermore, the first elastic reset element is a compression spring, and the second elastic reset element is a tension spring.

[0020] Furthermore, the alarm actuator is used to emit any one of the following: an audible alarm signal, a visual alarm signal, and an audible and visual alarm signal.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Since the first elastic reset member is located between the first conductive component and the second conductive component and is used to apply a first elastic force to the second conductive component to separate the first conductive component and the second conductive component, even if the rope assembly undergoes a momentary small displacement due to wind load, temperature change or animal disturbance, it cannot overcome the first elastic force applied by the first elastic reset member to make the first conductive component contact the second conductive component. This effectively blocks the conversion path of non-hazardous environmental interference into false alarm signals and improves the anti-interference capability of this slope crack monitoring and early warning device under complex field conditions.

[0023] 2. Based on the fact that the second elastic reset member is located between the second conductive component and the third conductive component, and is used to apply a second elastic force to the second conductive component so that the second conductive component and the third conductive component abut against each other, and the tension is less than the first elastic force but greater than the second elastic force, so that the first conductive component and the third conductive component are separated from the second conductive component respectively, the second elastic force provided by the second elastic reset member is balanced by the tension of the pull rope assembly under normal conditions, and only manifests as a tendency for the second conductive component to move towards the third conductive component; when the pull rope assembly breaks due to slope deformation, the tension disappears, and the tendency is converted into actual displacement, driving the second conductive component and the third conductive component to reliably abut against each other and close the electrical circuit; this mechanical self-triggering mechanism does not rely on external power supply or communication link, and can still ensure that the alarm function does not fail in extreme scenarios such as cable breakage and power failure, improving the reliability of the monitoring and early warning system in the disaster-prone stage.

[0024] 3. When the rope assembly is tightened or broken due to slope deformation, the second conductive component abuts against the first conductive component or the third conductive component respectively, forming an electrical circuit to trigger the alarm actuator. Therefore, rope tightening and rope breakage activate independent and mutually exclusive electrical paths, enabling the remote monitoring terminal to distinguish the evolution stage of slope deformation according to the circuit status, providing a clear technical basis for graded early warning and differentiated emergency response.

[0025] 4. Based on the tension state of the first, second, and third conductive components through the pull rope assembly and the elastic cooperation of the first and second elastic reset components, they can be separated or abutted. Under tension or breakage conditions, they can form independent electrical circuits to trigger the alarm execution mechanism. Therefore, the entire monitoring and early warning process is completed by a purely mechanical structure and circuit switching, without relying on sensor signal acquisition, data processing units, or external energy supply. This simplifies the architecture of the entire monitoring and early warning system and improves the stability and maintenance-free nature of this slope crack monitoring and early warning device in long-term field deployment.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] See Figures 1-3A preferred embodiment of the present invention provides a monitoring and early warning device for slope cracks, comprising: an alarm execution mechanism 1, an alarm triggering mechanism 2, and a rope assembly 3; the alarm execution mechanism 1 is used to issue an alarm signal; the alarm triggering mechanism 2 is disposed at the second end of the deformation direction of the slope, and the alarm triggering mechanism 2 includes a first conductive component 21, a second conductive component 22, a third conductive component 23, a first elastic reset component 24, and a second elastic reset component 25; the first conductive component 21, the second conductive component 22, and the third conductive component 23 are arranged sequentially along a first direction perpendicular to the deformation direction of the slope, and the second conductive component... Component 22 is movably configured, and the first conductive component 21, the second conductive component 22, and the third conductive component 23 are respectively electrically connected to the alarm actuator 1; the first elastic reset component 24 is disposed between the first conductive component 21 and the second conductive component 22, and is used to apply a first elastic force to the second conductive component 22 to separate the first conductive component 21 from the second conductive component 22; the second elastic reset component 25 is disposed between the second conductive component 22 and the third conductive component 23, and is used to apply a second elastic force to the second conductive component 22 to separate the second conductive component 22 from the third conductive component 23. The third conductive component 23 abuts against each other; the pull rope assembly 3 extends along the deformation direction of the slope, the first end of the pull rope assembly 3 is used to connect with the second end of the slope in the deformation direction, the second end of the pull rope assembly 3 is connected to the second conductive component 22, and the pull rope assembly 3 is used to apply a pulling force to the second conductive component 22 in a second direction, which is opposite to the first direction. The pulling force is less than the first elastic force and greater than the second elastic force, so that the first conductive component 21 and the third conductive component 23 are respectively separated from the second conductive component 22; when the pull rope assembly 3 is tightened due to slope deformation, The second conductive component 22 moves toward the first conductive component 21 along with the pull rope assembly 3, causing the second conductive component 22 to come into contact with the first conductive component 21 and form an electrical circuit to trigger the alarm actuator 1. When the pull rope assembly 3 breaks due to slope deformation, the tension applied by the pull rope assembly 3 disappears, and the second conductive component 22 moves toward the third conductive component 23 under the elastic force of the second elastic reset member 25, causing the second conductive component 22 to come into contact with the third conductive component 23 and form an electrical circuit to trigger the alarm actuator 1.

[0034] In practical application of the slope crack monitoring and early warning device, the alarm triggering mechanism 2 is first fixedly installed in a stable area along the slope deformation direction, ensuring that the first conductive component 21, the second conductive component 22, and the third conductive component 23 are arranged sequentially in the same direction, and that the first elastic reset component 24 and the second elastic reset component 25 are in their normal working positions. Then, one end of the pull rope assembly 3 is connected to the potential slip zone of the slope, and the other end is reliably connected to the second conductive component 22. After installation, the pull rope assembly 3 is in a moderately tensioned state, applying a pulling force towards the potential slip zone to the second conductive component 22. In this initial working state, this pulling force prevents the second conductive component 22 from contacting either the first conductive component 21 or the third conductive component 23; both electrical circuits remain open, and the alarm actuator 1 is in an untriggered state. When the slope deforms, causing the pull rope to be further tightened, the second conductive component 22 moves towards the first conductive component 21 under the pulling force, eventually contacting it, thus forming an electrical circuit. The completion of this electrical circuit triggers the alarm actuator 1 to issue an alarm signal. When a slope experiences severe instability, causing the guy rope to break or detach from the connection point, the tension acting on the second conductive component 22 disappears. At this time, under the action of the second elastic reset member 25, the second conductive component 22 moves towards the third conductive component 23 and comes into contact with it, forming another electrical circuit. The completion of this electrical circuit will also trigger the alarm actuator 1 to issue an alarm signal. In both of the above scenarios, the alarm actuator 1 can issue the same or different alarm signals depending on the specific design. Through this method, the slope crack monitoring and early warning device can effectively monitor two typical risk states of slope: slow deformation and sudden fracture, and promptly activate the alarm mechanism when either anomaly occurs, achieving early warning and emergency response to geological disasters.

[0035] Based on the fact that the first elastic reset member 24 is located between the first conductive component 21 and the second conductive component 22, and is used to apply a first elastic force to the second conductive component 22 so that the first conductive component 21 and the second conductive component 22 are separated, even if the rope assembly 3 is momentarily displaced due to wind load, temperature change or animal disturbance, it cannot overcome the first elastic force applied by the first elastic reset member 24 to make the first conductive component 21 and the second conductive component 22 come into contact. This effectively blocks the conversion path of non-hazardous environmental interference into false alarm signals, and improves the anti-interference capability of this slope crack monitoring and early warning device under complex field conditions. The second elastic reset member 25 is located between the second conductive component 22 and the third conductive component 23, and is used to apply a second elastic force to the second conductive component 22 so that the second conductive component 22 and the third conductive component 23 abut against each other. The tension is less than the first elastic force but greater than the second elastic force, so that the first conductive component 21 and the third conductive component 23 are separated from the second conductive component 22 respectively. Therefore, the second elastic force provided by the second elastic reset member 25 is balanced by the tension of the pull rope assembly 3 under normal conditions, and only manifests as a tendency for the second conductive component 22 to move toward the third conductive component 23. When the pull rope assembly 3 breaks due to slope deformation, the tension disappears, and the tendency is converted into actual displacement, driving the second conductive component 22 and the third conductive component 23 to reliably abut against each other and close the electrical circuit. This mechanical self-triggering mechanism does not rely on external power supply or communication link, and can still ensure that the alarm function does not fail in extreme scenarios such as cable breakage and power outage, improving the reliability of the monitoring and early warning system in the disaster-prone stage. When the rope assembly 3 is tightened or broken due to slope deformation, the second conductive component 22 abuts against the first conductive component 21 or the third conductive component 23 respectively, forming an electrical circuit to trigger the alarm execution mechanism 1. Therefore, rope tightening and rope breakage activate independent and mutually exclusive electrical paths, allowing the remote monitoring terminal to distinguish the evolution stage of slope deformation based on the circuit status, providing a clear technical basis for graded early warning and differentiated emergency response. Based on the separation or abutment of the first conductive component 21, second conductive component 22, and third conductive component 23 through the tension state of the rope assembly 3 and the elastic cooperation of the first elastic reset component 24 and the second elastic reset component 25, and the formation of independent electrical circuits under tightening or breakage conditions to trigger the alarm execution mechanism 1, the entire monitoring and early warning process is completed by a purely mechanical structure and circuit switching, without relying on sensor signal acquisition, data processing units, or external power supply. This simplifies the architecture of the entire monitoring and early warning system and improves the stability and maintenance-free nature of this slope crack monitoring and early warning device in long-term field deployment.

[0036] Preferably, in this embodiment, the rope assembly 3 includes an elastic rope 31 and multiple guy wires 32. The multiple guy wires 32 are distributed sequentially at intervals along a direction perpendicular to the deformation direction of the slope. The first end of each guy wire 32 is used to connect to the first end of the deformation direction of the slope, and the second end of each guy wire 32 is connected to the elastic rope 31. The elastic rope 31 extends along the first direction, with its first end connected to the slope and its second end connected to the second conductive component 22. The elastic rope 31 is used to transmit the force of the guy wires 32 along a direction perpendicular to the deformation direction of the slope to the second conductive component 22, thereby driving the second conductive component 22 to make corresponding displacements. This structure synchronously senses the local deformation at different locations of the slope through the multi-point distributed guy wires 32, and couples and converts the non-collinear tension generated by each guy wire 32 into a concentrated equivalent tension along the first direction with the help of the elastic rope 31, which then acts on the second conductive component 22. Therefore, the complex deformation patterns of slope cracks, such as irregular expansion, non-uniform opening, or local displacement, can be effectively transformed into a unified mechanical displacement signal that can trigger an alarm mechanism. This design improves the response sensitivity, spatial representativeness, and overall monitoring reliability of the slope crack monitoring and early warning device for common non-uniform crack deformations in actual engineering projects.

[0037] Preferably, in this embodiment, a slope crack monitoring and early warning device further includes a protective substrate 4, which has a housing space 41 in which the alarm triggering mechanism 2 is disposed. This structure physically encapsulates and isolates various key components of the alarm triggering mechanism 2 through the protective substrate 4, effectively blocking external interference factors such as rainwater, dust, insect intrusion, and unintentional human contact. This avoids problems such as electrical contact degradation due to environmental erosion, corrosion failure of elastic components, or mechanical movement obstruction caused by foreign objects, thereby reducing the risk of false alarms or functional failures and significantly improving the long-term operational reliability, stability, and service life of this slope crack monitoring and early warning device in complex outdoor environments.

[0038] Preferably, in this embodiment, the protective base 4 is provided with a guide portion 42, and the elastic rope 31 is slidably threaded through the guide portion 42 to guide the elastic rope 31 to pull the second conductive component 22 in a direction perpendicular to the deformation direction of the slope. The guide portion 42 can be constructed as a through hole, a groove, or other suitable limiting structure. By constraining the movement trajectory of the elastic rope 31 through the guide portion 42, the elastic rope 31 is effectively prevented from swaying, twisting, or lateral swaying during the force application process, thereby avoiding the introduction of unexpected lateral force components. This design ensures that the tension is always smoothly and linearly transmitted to the second conductive component 22 in a preset direction, which not only improves the reliability of mechanical transmission but also ensures the correspondence between the displacement response of the second conductive component 22 and the actual deformation of the slope, thereby improving the detection accuracy and repeatability of the entire slope crack monitoring and early warning device.

[0039] Preferably, in this embodiment, the protective substrate 4 is a component made of a transparent material. The transparent material can be selected from polycarbonate, polymethyl methacrylate, or other engineering plastics with good light transmittance, weather resistance, and mechanical strength. This structural design allows maintenance personnel to directly observe the status of key components inside the accommodating space 41 without disassembling the device, including the real-time position of the second conductive component 22, and whether the first elastic reset component 24 and the second elastic reset component 25 have deformed, broken, or fatigued. This allows for quick determination of whether the alarm triggering mechanism 2 is currently in normal working condition, or identification of typical fault causes such as loose pull ropes, stuck elastic components, and oxidized conductive contacts. This visualization design reduces the technical threshold, operating time, and labor costs for on-site inspection and maintenance, and improves the maintainability and life-cycle management efficiency of the slope crack monitoring and early warning device.

[0040] Preferably, in this embodiment, each of the pull wires 32 has an anchor 5 at the end furthest from the alarm triggering mechanism 2. The anchor 5 is used to fix the pull wire 32 to the stable area of ​​the slope. The anchor 5 can be an expansion bolt, a soil anchor, a chemical anchor, or other reliable anchoring structure suitable for soil and rock masses. Its specific form can be selected according to the slope geological conditions and engineering requirements. This structure ensures that the fixed end of the pull wire 32 will not be displaced due to loosening of the surface soil, weathering and peeling, or shallow slippage, thereby effectively isolating non-crack deformation factors from interfering with the monitoring structure. As a result, the tension borne by the pull wire assembly 3 can truly and accurately reflect the actual opening amount or displacement change of the slope cracks, avoiding data distortion or false alarms caused by anchor point failure. This design improves the measurement accuracy, long-term stability, and reliability of the warning signal of the entire slope monitoring and early warning device.

[0041] Preferably, in this embodiment, the alarm triggering mechanism 2 further includes a first slip member 26, a second slip member 27, and a support member 28; the first slip member 26 is disposed between the second conductive component 22 and the first conductive component 21, and the second slip member 27 is disposed between the second conductive component 22 and the third conductive component; the support member 28 is used to support the first slip member 26 and the second slip member 27; when the pull rope assembly 3 is tightened due to slope deformation, the second conductive component 22 moves toward the first conductive component 21 and pushes the first slip member 26 away from the support member 28; when the pull rope assembly 3 breaks due to slope deformation, the second conductive component 22 moves toward the third conductive component 23 and pushes the second slip member 27 away from the support member 28; after the first slip member 26 or the second slip member 27 is detached from the support member 28, it falls down and is used to provide a mechanical alarm indication or trigger an auxiliary alarm signal. The above structure achieves differentiated responses to different working conditions through the physical detachment of the slip members. Once the slip element detaches from the support element 28, it falls due to gravity, resulting in an irreversible mechanical change that can be directly visually identified by on-site personnel, serving as a clear indication of significant slope deformation or rope failure. Simultaneously, the falling action of the slip element triggers a microswitch or other contact-type sensor located below, outputting an auxiliary electrical signal that, together with the main circuit's conduction signal, forms a dual-channel alarm output for mutual verification. This design not only improves the traceability of alarm events and the efficiency of on-site confirmation but also effectively avoids misjudgments caused by the elastic reset mechanism rebounding under transient disturbances, achieving reliable locking and multiple verification of abnormal events.

[0042] Preferably, in this embodiment, the pull rope assembly 3 is provided with a friction resistance mechanism 33. The friction resistance mechanism 33 is used to apply a preset friction resistance to the movement of the pull rope assembly 3 to suppress disturbances not caused by slope deformation. The friction resistance mechanism 33 is configured to provide controllable static friction when the pull rope assembly 3 undergoes a small displacement. Thus, instantaneous, non-structural disturbances such as wind vibration, animal contact, vegetation growth, or thermal expansion and contraction of materials caused by temperature changes cannot drive the second conductive component 22 to produce an effective displacement because the resulting tension is insufficient to overcome the preset friction resistance, thereby avoiding false triggering of the alarm circuit. Only when the slope undergoes a continuous deformation with a displacement exceeding a set threshold can the tension on the pull rope assembly 3 overcome the friction resistance, push the second conductive component 22 to the trigger position, and complete the alarm action. This design improves the robustness of the slope monitoring and early warning device to environmental interference, effectively reducing the false alarm rate while ensuring a high-sensitivity response to real disaster deformation.

[0043] Preferably, in this embodiment, the first elastic reset member 24 is a compression spring, and the second elastic reset member 25 is a tension spring. The compression spring is in a pre-compressed state under normal conditions, applying a continuous pushing force to the second conductive member 22, keeping it separated from the first conductive member 21, ensuring the alarm circuit is in an open state under normal operating conditions. The tension spring is connected between the second conductive member 22 and the third conductive member 23. After the pull rope assembly 3 breaks, its restoring tension drives the second conductive member 22 to move towards the third conductive member 23, closing the circuit to trigger the breakage alarm. Using compression springs and tension springs to correspond to pushing and pulling conditions respectively not only matches the mechanical requirements of their respective working modes but also results in a simple structure, clear response, high reliability, and ease of on-site assembly and parameter adjustment.

[0044] Preferably, in this embodiment, the alarm actuator 1 is used to emit any one of an audible alarm signal, an optical alarm signal, and an audible-optical alarm signal. The alarm actuator 1 can flexibly select the alarm form according to the environmental conditions and user needs of the actual application scenario: in noisy outdoor environments, a high-brightness optical alarm can be prioritized to ensure visibility; in low-light or nighttime conditions, an audible alarm can be activated to enhance the warning effect; and at critical monitoring points with high reliability requirements, both audible and optical alarms can be activated simultaneously to achieve multi-sensory coverage and improve the efficiency of alarm information transmission and the timeliness of response.

The rope assembly (3) is used to apply a pulling force toward the second conductive component (22) in a second direction, which is opposite to the first direction.
