Description

Technical Field

[0001] This utility model relates to the field of bridge construction and slope treatment, specifically a highway bridge and slope collapse monitoring device based on photoelectric dual-loop circuit. Background Technology

[0002] With the increase in traffic load, natural environmental erosion, and the extension of the service life of engineering projects, bridge beams are prone to deformation such as bending and cracks, and slope foundations may be prone to landslides, collapses, and other dangers. If timely monitoring and early warning are not provided, it will seriously threaten the safety of people's lives and property.

[0003] Currently, the commonly used bridge slope monitoring technologies mainly include manual inspection and sensor monitoring. Manual inspection relies on on-site observation and measurement by staff, which is not only inefficient and labor-intensive, but also limited by factors such as severe weather and complex terrain, making it difficult to achieve all-weather, high-precision monitoring, and easily overlooking early minor deformation hazards. While sensor monitoring technology has to some extent compensated for the shortcomings of manual inspection, existing monitoring devices still have many deficiencies: First, during installation, the unevenness of bridge beam surfaces and slope substrate surfaces makes it difficult for the device to maintain a stable rigid connection with the monitoring target, easily leading to initial installation errors and affecting the accuracy of monitoring data. Second, some monitoring devices use only a single fixed structure, which is prone to displacement under the influence of external forces such as vehicle vibration and wind, causing the monitoring position to shift and further reducing monitoring reliability. Third, most monitoring systems use single-loop signal transmission; once the loop fails, monitoring will be interrupted, and the lack of comparison criteria for a single signal makes it difficult to distinguish between actual deformation and equipment failure, easily leading to false alarms or missed alarms. Fourth, existing devices do not adequately constrain the movement of stabilizing components; when the monitoring target deforms, the stabilizing components are prone to lateral displacement, failing to accurately reflect the deformation, thus affecting monitoring accuracy and delaying emergency response. In view of this, we propose a highway bridge and slope collapse monitoring device based on a photoelectric dual-loop circuit to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a highway bridge and slope collapse monitoring device based on photoelectric dual-loop, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highway bridge and slope collapse monitoring device based on photoelectric dual-loop, comprising a mounting base, a leveling block, an installation component, a monitoring optical fiber, a monitoring cable, and a limiting mechanism. The mounting base has an installation groove, and a threaded transmission limiting mechanism is provided in the installation groove. Multiple connecting seats are arranged at equal intervals in the installation groove. A return spring is provided on one side of the connecting seat, and a stabilizing component is provided on the side of the return spring away from the connecting seat. Guide grooves are provided on both sides of the installation groove near the stabilizing component, and guide blocks are fixedly connected to both sides of the stabilizing component. The guide blocks are located in the guide grooves.

[0006] Preferably, the limiting mechanism includes an adjusting block, a limiting block, a threaded rod, a knob, a first bevel gear, a second bevel gear, and a rotating rod. The rotating rod is movably connected inside the mounting base. A knob is provided on one side of the rotating rod that passes through the mounting base, and a second bevel gear is fixedly connected to the side of the rotating rod away from the knob. A first bevel gear is inclinedly provided on the side of the mounting base near the second bevel gear. The second bevel gear and the first bevel gear mesh with each other. A threaded rod is fixed to one side of the first bevel gear, and an adjusting block is threadedly connected to the threaded rod. A limiting block is fixedly connected to one side of the adjusting block, and the limiting block and the stabilizing component cooperate with each other.

[0007] Preferably, leveling blocks are evenly spaced on one side of the mounting base, and mounting components are symmetrically arranged on both sides of the mounting base, with magnetic blocks on the upper side of the mounting base.

[0008] Preferably, monitoring optical fibers and monitoring cables are arranged at equal intervals inside the connector, and monitoring equipment is installed inside the mounting base, with the monitoring optical fibers and monitoring cables connected to the monitoring equipment through the connector.

[0009] Preferably, the monitoring optical fiber and monitoring cable are located within the stabilizing element.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The mounting brackets on both sides of the mounting base are used to fix the device to the bridge beam and slope base, ensuring a rigid connection between the device and the monitoring target. The leveling blocks set at equal intervals on one side of the mounting base can be adjusted during installation by increasing or decreasing the thickness of the leveling blocks or fine-tuning their position, so that the entire mounting base is at a preset angle that is horizontal or in contact with the monitoring surface, eliminating the initial error caused by unevenness of the mounting surface. The magnetic blocks on the upper side of the mounting base can assist in adsorption and fixation, enhancing the connection stability between the device and the monitoring target and preventing the device from shifting due to vibration or slight external force.

[0012] 2. The operator rotates the knob, causing the rotating rod fixed to it to rotate. The second bevel gear at the other end of the rotating rod rotates synchronously and drives the first bevel gear through gear meshing. The first bevel gear drives the threaded rod fixed on the same axis to rotate. Since the threaded rod and the adjusting block are connected by threads, the rotation of the threaded rod is converted into linear movement of the adjusting block. The adjusting block drives the limit block fixed on one side to move, and finally makes the limit block fit tightly with the stabilizing component, thereby fixing the position of the stabilizing component.

[0013] 3. The guide blocks on both sides of the stabilizer are embedded in the guide groove of the mounting slot, which restricts the stabilizer to move only along the direction of the guide groove and avoids lateral displacement. One side of the stabilizer is connected to the connecting seat through a reset spring. When the monitored target is deformed, the monitoring optical fiber and monitoring cable undergo slight deformation. If this causes any circuit to be disconnected, the system will automatically switch to the backup circuit and trigger an alarm to provide a signal source for photoelectric monitoring.

[0014] 4. The monitoring equipment simultaneously receives optical signal data from optical fibers and electrical signal data from cables. By comparing data from both loops, the monitoring accuracy is improved. When any loop detects an abnormal parameter that exceeds the threshold, the monitoring equipment first issues a suspected deformation warning. If both loops detect an abnormality and the data are consistent, a collapse risk warning is immediately issued to buy time for emergency response. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figures 1-4 As shown, the present invention proposes a highway bridge and slope collapse monitoring device based on photoelectric dual-loop, including a mounting base 1, a leveling block 2, a mounting component 3, a monitoring optical fiber 4, a monitoring cable 5, and a limiting mechanism 6. The mounting base 1 has a mounting groove 7, and a threaded transmission limiting mechanism 6 is provided in the mounting groove 7. Multiple connecting seats 8 are arranged at equal intervals in the mounting groove 7. A return spring 9 is provided on one side of the connecting seat 8. A stabilizing component 12 is provided on the side of the return spring 9 away from the connecting seat 8. Guide grooves 10 are opened on both sides of the mounting groove 7 near the stabilizing component 12, and guide blocks 11 are fixedly connected to both sides of the stabilizing component 12. The guide blocks 11 are located in the guide grooves 10.

[0022] In an optional embodiment, the limiting mechanism 6 includes an adjusting block 601, a limiting block 602, a threaded rod 603, a knob 604, a first bevel gear 605, a second bevel gear 606, and a rotating rod 607. The rotating rod 607 is movably connected inside the mounting base 1. A knob 604 is provided on one side of the rotating rod 607 that passes through the mounting base 1, and a second bevel gear 606 is fixedly connected to the side of the rotating rod 607 away from the knob 604. A first bevel gear 605 is inclinedly provided on the side of the mounting base 1 near the second bevel gear 606. The second bevel gear 606 and the first bevel gear 605 mesh with each other. A threaded rod 603 is fixed to one side of the first bevel gear 605. An adjusting block 601 is threadedly connected to the threaded rod 603. A limiting block 602 is fixedly connected to one side of the adjusting block 601. The limiting block 602 cooperates with the stabilizing member 12.

[0023] The operator rotates the knob 604, which drives the rotating rod 607 fixed thereto to rotate. The second bevel gear 606 at the other end of the rotating rod 607 rotates synchronously and drives the first bevel gear 605 through gear meshing. The first bevel gear 605 drives the threaded rod 603 fixed on the same axis to rotate. Since the threaded rod 603 and the adjusting block 601 are threadedly connected, the rotation of the threaded rod 603 is converted into the linear movement of the adjusting block 601. The adjusting block 601 drives the limit block 602 fixed on one side to move, and finally makes the limit block 602 fit tightly with the stabilizer 12, thereby fixing the position of the stabilizer 12.

[0024] The guide blocks 11 on both sides of the stabilizer 12 are embedded in the guide grooves 10 of the mounting groove 7, which restricts the stabilizer 12 to move only along the direction of the guide grooves 10 and avoids lateral displacement. One side of the stabilizer 12 is connected to the connecting seat 8 through the reset spring 9. When the monitored target is deformed, the monitoring optical fiber 4 and the monitoring cable 5 undergo slight deformation. When this causes any circuit to be disconnected, the system will automatically switch to the backup circuit and trigger an alarm to provide a signal source for photoelectric monitoring.

[0025] In an optional embodiment, leveling blocks 2 are provided at equal intervals on one side of the mounting base 1, and mounting parts 3 are symmetrically arranged on both sides of the mounting base 1. A magnetic block is provided on the upper side of the mounting base 1.

[0026] The mounting parts 3 on both sides of the mounting base 1 are used to fix the device to the bridge beam and slope base, ensuring a rigid connection between the device and the monitoring target. The leveling blocks 2 are set at equal intervals on one side of the mounting base 1. During installation, the thickness of the leveling blocks is increased or decreased or their positions are finely adjusted to make the mounting base 1 horizontal or at a preset angle that fits the monitoring surface, eliminating the initial error caused by unevenness of the installation surface. The magnetic blocks on the upper side of the mounting base 1 can assist in adsorption and fixation, enhance the connection stability between the device and the monitoring target, and avoid the device from shifting due to vibration or slight external force.

[0027] In an optional embodiment, monitoring optical fibers 4 and monitoring cables 5 are respectively arranged at equal intervals in the connecting seat 8, and monitoring equipment is provided in the mounting seat 1, and the monitoring optical fibers 4 and monitoring cables 5 are connected to the monitoring equipment through the connecting seat 8.

[0028] The monitoring equipment simultaneously receives optical signal data from optical fibers and electrical signal data from cables. By comparing data from both loops, the monitoring accuracy is improved. When either loop detects an abnormal parameter that exceeds the threshold, the monitoring equipment first issues a suspected deformation warning. If both loops detect an abnormality and the data are consistent, a collapse risk warning is immediately issued to buy time for emergency response.

[0029] In an optional embodiment, the monitoring optical fiber 4 and the monitoring cable 5 are located within the stabilizer 12.

[0030] The working principle of this utility model is as follows: When using the device, the mounting parts 3 on both sides of the mounting base 1 are used to fix the device on the bridge beam and the slope base to ensure that the device is rigidly connected to the monitoring target. The leveling blocks 2 are set at equal intervals on one side of the mounting base 1. During installation, by increasing or decreasing the thickness of the leveling blocks or finely adjusting their position, the mounting base 1 is made to be horizontal or at a preset angle that is in contact with the monitoring surface, eliminating the initial error caused by unevenness of the mounting surface. The magnetic block on the upper side of the mounting base 1 can assist in adsorption and fixation, enhance the connection stability between the device and the monitoring target, and avoid the device from shifting due to vibration or slight external force.

[0031] The operator rotates the knob 604, which drives the rotating rod 607 fixed thereto to rotate. The second bevel gear 606 at the other end of the rotating rod 607 rotates synchronously and drives the first bevel gear 605 through gear meshing. The first bevel gear 605 drives the threaded rod 603 fixed on the same axis to rotate. Since the threaded rod 603 and the adjusting block 601 are threadedly connected, the rotation of the threaded rod 603 is converted into the linear movement of the adjusting block 601. The adjusting block 601 drives the limit block 602 fixed on one side to move, and finally makes the limit block 602 fit tightly with the stabilizer 12, thereby fixing the position of the stabilizer 12.

[0032] The guide blocks 11 on both sides of the stabilizer 12 are embedded in the guide grooves 10 of the mounting groove 7, which restricts the stabilizer 12 to move only along the direction of the guide grooves 10 and avoids lateral displacement. One side of the stabilizer 12 is connected to the connecting seat 8 through the reset spring 9. When the monitored target is deformed, the monitoring fiber 4 and the monitoring cable 5 undergo slight deformation. When this causes any circuit to be disconnected, the system will automatically switch to the backup circuit and trigger an alarm to provide a signal source for photoelectric monitoring.

[0033] The monitoring equipment simultaneously receives optical signal data from optical fibers and electrical signal data from cables. By comparing data from both loops, the monitoring accuracy is improved. When either loop detects an abnormal parameter that exceeds the threshold, the monitoring equipment first issues a suspected deformation warning. If both loops detect an abnormality and the data are consistent, a collapse risk warning is immediately issued to buy time for emergency response.
