Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster monitoring, and particularly to a mechanical rope for deploying or recovering geological disaster emergency monitoring equipment. Background Art

[0002] In areas where geological disasters such as large-scale landslides occur, the terrain is often complex, and it is difficult for emergency personnel to enter the site for monitoring. Therefore, using unmanned aerial vehicles to achieve the aerial deployment and recovery of monitoring equipment has become a key technical means.

[0003] Currently, the existing technology mainly deploys geological disaster monitoring equipment at high altitudes by drones, such as using inertial navigation or manual control to achieve the deployment of the equipment. However, such technologies still have significant defects in practical applications:

[0004] Insufficient deployment accuracy: The navigation methods relied on by the existing technology are difficult to adapt to complex terrains (such as steep slopes and dense forests) and environmental interferences (such as strong winds), resulting in large deviations in the landing points of the equipment and unstable tilting postures, affecting the reliability of monitoring data;

[0005] Weak recovery mechanism: Most monitoring equipment is designed for single-use and lacks an efficient recovery plan. Although some equipment is equipped with retractable brackets or moving components, it is difficult to achieve stable grasping through an aerial platform in the harsh post-disaster environment, resulting in waste of resources and increased costs;

[0006] Poor environmental adaptability: The performance of the existing devices is limited in extreme weather (such as strong winds and low temperatures), and it is impossible to achieve precise positioning and attitude correction by dynamically adjusting the state of the rope body.

[0007] In view of the above technical bottlenecks, it is urgent to develop a mechanical rope device that can adapt to complex terrains and harsh environments and has the capabilities of high-precision deployment and reliable recovery to improve the timeliness and safety of geological disaster emergency monitoring.

Detailed implementation mode

[0030] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation modes and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention. In the description of the present invention, it should be noted that the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] The embodiments shown in the present invention will be described below with reference to the accompanying drawings. Refer to Figure 1 , the rope body of the mechanical rope for deploying or retrieving geological disaster emergency monitoring equipment shown in this embodiment is composed of several groups of knots 1. Refer to Figure 2 and Figure 3 , each group of knots 1 includes: a central support part 11, a first partition board 12 and several groups of driving parts 13. The central support parts 11 of each group of knots 1 are connected to each other in sequence. The central support part 11 is made of a flexible material and can be integrally formed or separately formed. The first partition board 12 is arranged around the outside of the central support part 11 along the axial direction of the knot. Several groups of driving parts 13 are arranged between the first partition boards 12 of two adjacent knots 1. Refer to Figure 4 , and the driving parts 13 are evenly distributed along the radial direction of the knot 1.

[0032] Since the central support part 11 is made of a flexible material, the relative angle between the first partition boards 12 of adjacent knots 1 can be changed under the action of an external force. In this embodiment, the relative angle between the first partition boards 12 of adjacent knots 1 is adjusted by the driving part 13. And because the driving parts 13 are evenly distributed along the radial direction of the knot 1, driving the driving parts 13 in different directions can make the knot 1 tilt at the corresponding angle, so that the overall posture of the mechanical rope can be adjusted.

[0033] Specifically, the driving part 13 further includes: a moving block 131 and several groups of first driving components 132. Each group of first driving components 132 has an expansion part 1321 and a heating module 1322. To limit the movement of the moving block 131, the expansion part 1321 has an internal chamber, and the heating module 1322 is arranged in the internal chamber, which can directly heat the gas in the internal chamber or, as Figure 3 shown, be arranged in contact with the expansion part 1321 to heat the gas in the internal chamber through heat conduction. Several groups of first driving components 132 are fitted into a first contour, and the first contour fits the outer shape of the moving block 131. The moving block 131 is movably arranged between the first contour and the first partition 12.

[0034] When the heating module 1322 is powered on, the inside of the expansion part 1321 expands due to heat, pressing the moving block 131, as Figure 3 shown, making it in contact with the first partition 12 and further driving the first partition 12, so that the relative angle between the first partition 12 of the adjacent knot 1 changes. When the heating module 1322 is powered off, the expansion part 1321 returns to its original state. Thus, by controlling the expansion degree of the expansion part 1321, the bending degree of the rope body can be controlled. To obtain a better expansion effect, the inside of the expansion part 1321 is filled with a low-boiling liquid. To accurately control the expansion degree of the expansion part 1321, a temperature sensor is further arranged in the expansion part 1321, and the temperature sensor is used to monitor the temperature inside the expansion part 1321. Referring to Figure 4 , by controlling the power on and off of the heating modules 1322 in different directions, the knot 1 can be driven to bend in the corresponding direction.

[0035] In this embodiment, the moving block 131 is in the shape of a water droplet, and its spherical end is arranged towards the side of the first driving component 132, so the first contour is arc-shaped. The knot 1 further includes a circuit control box 14, and the circuit control box 14 is used to control the power-on state of the heating module 1322. An inclination sensor (not shown in the figure) is further arranged in the knot 1, and the inclination sensor is used to obtain the inclination angle of each group of knots 1. The mechanical rope shown in this embodiment further includes an electronic compass (not shown in the figure), and the electronic compass is used to determine the direction of the preset mark of the mechanical rope and the direction in which the mechanical rope needs to bend.

[0036] The mechanical rope shown in this embodiment further includes a first outer layer 2 made of a polyester polymer. The knot 1 is wrapped by the first outer layer 2. The knot 1 further includes: a stress sensor 15 disposed on the inner wall of the first outer layer 2, and the stress sensor 15 can monitor the deformation state of the mechanical rope in real time. The central support portion 11 has a hollow structure, and a steel wire rope 4 wrapped by a second outer layer 3 is disposed in the hollow structure. A plurality of groups of second partition plates 111 are disposed along the radial direction on the inner side of the central support portion 11, and the second partition plates 111 are in contact with the second outer layer 3 of the steel wire rope 4. A communication cable 5 is further disposed between two groups of second partition plates 111. In order to prevent the communication cable 5 from shaking in the hollow structure, each communication cable 5 is disposed in the space formed by the semi-circular partition layer 6 and the inner wall of the central support portion 11.

[0037] Reference Figure 5 , the mechanical rope shown in this embodiment further includes a first docking head 7, the first docking head 7 is fixedly connected to the last group of knots 1 of the rope body, and the corresponding second docking head 8 is fixedly connected to the monitoring device. The first docking head 7 is structurally connected to the second docking head 8. When connecting, as shown in Figure 5 , and when separating, as shown in Figure 6 .

[0038] Specifically, reference Figure 5 and Figure 6, a sliding ejector rod 71 and an annular electromagnet 72 are provided at the lower part of the first docking head 7. Correspondingly, the second docking head 8 is provided with a linkage lock 81 and a permanent magnet 82. When recovering the monitoring device, the first docking head 7 descends vertically under the control of the mechanical rope and approaches the second docking head 8. An ultrasonic sensor 73 and a vision sensor 74 are also provided at the lower part of the first docking head 7. The ultrasonic sensor 73 senses the distance, and the vision sensor 74 obtains external environment information, especially the vision positioning and recognition ring 83 provided on the second docking head 8, so that the first docking head 7 can be accurately docked with the second docking head 8. The permanent magnet 82 of the second docking head 8 is attracted by the magnetic force of the annular electromagnet 72 of the first docking head 7, so the second docking head 8 automatically completes the docking with the first docking head 7. To make the docking smoother, the first docking head 7 is set to be conical, and the second docking head 8 is correspondingly provided with a conical pit. After the docking is completed, the sliding ejector rod 71 presses down on the linkage lock 81, so the linkage lock 81 drives one end of the transmission piece 85 through the biasing fixed shaft 86, and the other end of the transmission piece 85 pushes the locking tongue 84 to embed into the annular locking groove 75 of the first docking head 7. Even if there is a power outage, the first docking head 7 and the second docking head 8 will not disconnect. When it is necessary to deploy the monitoring device, control the sliding ejector rod 71 to move upward, so the linkage lock 81 also moves upward, so the locking tongue 85 moves out of the annular locking groove 75, and the unlocking is completed. Then, cut off the power supply of the annular electromagnet 72 or generate a repulsive magnetic force to separate the first docking head 7 from the second docking head 8, and the monitoring device can complete the deployment by free fall. When encountering strong wind and bad weather, the attitude of the mechanical rope can also be adjusted. If the monitoring device is inclined, the attitude can also be adjusted through the mechanical rope to complete the docking of the first docking head 7 and the second docking head 8.
