Description

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

[0002] Areas where large-scale landslides and other geological disasters occur often have complex terrain, making it difficult for emergency personnel to enter the site for monitoring. Therefore, using unmanned aerial vehicles to achieve aerial delivery and recovery of monitoring equipment has become a key technical means.

[0003] At present, the existing technology mainly uses UAVs to carry geological disaster monitoring equipment for high-altitude deployment, such as using inertial navigation or manual control to achieve the deployment of equipment. However, this type of technology still has significant defects in practical applications: Insufficient placement accuracy: The navigation method relied on by existing technologies is difficult to adapt to complex terrain (such as steep slopes and dense forests) and environmental interference (such as strong winds), resulting in large deviations in the device's landing point and unstable attitude tilt, affecting the reliability of monitoring data; Weak recycling mechanism: Most monitoring equipment is designed for one-time use and lacks efficient recycling solutions. Although some equipment is equipped with retractable brackets or mobile components, it is difficult to achieve stable grabbing through aerial platforms in the harsh post-disaster environment, resulting in waste of resources and increased costs; Poor environmental adaptability: The performance of existing devices is limited in extreme weather conditions (such as strong winds and low temperatures), and it is impossible to achieve precise positioning and posture correction by dynamically adjusting the state of the rope.

Detailed implementation manners

[0019] 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 specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, 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.

[0020] The embodiments of 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 , the driving parts 13 are evenly distributed along the radial direction of the knot 1.

[0021] 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.

[0022] Specifically, the driving unit 13 further includes: a moving block 131 and a plurality of first driving components 132, each of which has an expansion unit 1321 and a heating module 1322. In order to limit the movement of the moving block 131, the expansion unit 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 can be used as Figure 3 As shown, the expansion part 1321 is arranged to heat the gas in the internal chamber by heat conduction. A plurality of first drive components 132 are fitted into a first contour, and the first contour is fitted with the shape of the motion block 131, and the motion block 131 is movably arranged between the first contour and the first partition 12.

[0023] When the heating module 1322 is powered on, the expansion part 1321 expands due to the heat, pressing the moving block 131. Figure 3 As shown, the expansion part 1321 contacts the first baffle 12 and further drives the first baffle 12, so that the relative angle between the expansion part 1321 and the first baffle 12 of the adjacent knot 1 changes. When the heating module 1322 is powered off, the expansion part 1321 returns to its original state. Therefore, by controlling the expansion degree of the expansion part 1321, the bending degree of the rope body can be controlled. In order to obtain a better expansion effect, the expansion part 1321 is filled with a low-boiling point liquid. In order to accurately control the expansion degree of the expansion part 1321, a temperature sensor is also provided in the expansion part 1321, and the temperature sensor is used to monitor the temperature in the expansion part 1321. Reference 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.

[0024] In this embodiment, the moving block 131 is in the shape of a teardrop, and its spherical end is arranged toward the first driving component 132, so that the first contour is an arc. The knot 1 also includes a circuit control box 14, which is used to control the power-on state of the heating module 1322. A tilt sensor (not shown in the figure) is also arranged in the knot 1, and the tilt sensor is used to obtain the tilt angle of each group of knots 1. The mechanical rope shown in this embodiment also includes an electronic compass (not shown in the figure), which is used to determine the direction of the preset mark of the mechanical rope and the direction in which the mechanical rope needs to be bent.

[0025] The mechanical rope shown in this embodiment also includes a first outer layer 2, the first outer layer 2 is made of polyester polymer, the knot 1 is wrapped by the first outer layer 2, and the knot 1 also includes: a stress sensor 15, the stress sensor 15 is arranged 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 part 11 has a hollow structure, and a steel wire rope 4 wrapped by a second outer layer 3 is arranged in the hollow structure. A plurality of groups of second partitions 111 are arranged along the radial direction on the inner side of the central support part 11, and the second partitions 111 are in contact with the second outer layer 3 of the steel wire rope 4. A communication cable 5 is also arranged between the two groups of second partitions 111. In order to prevent the communication cable 5 from shaking in the hollow structure, each communication cable 5 is arranged in the space surrounded by the semicircular partition 6 and the inner wall of the central support part 11.

[0026] refer to Figure 5 The mechanical rope shown in this embodiment also includes a first pair of joints 7, which are fixedly connected to the last group of knots 1 of the rope body, and the corresponding second pair of joints 8 are fixedly connected to the monitoring device. The first pair of joints 7 and the second pair of joints 8 are structurally connected. Figure 5 As shown, when separated Figure 6 shown.

[0027] Specifically, refer to Figure 5 and Figure 6The first pair of joints 7 has a sliding top rod 71 and an annular electromagnet 72 at the bottom, and the second pair of joints 8 has a linkage lock 81 and a permanent magnet 82. When the monitoring equipment is recovered, the first pair of joints 7 vertically descends under the control of the mechanical rope and approaches the second pair of joints 8. An ultrasonic sensor 73 and a visual sensor 74 are also arranged at the bottom of the first pair of joints 7. The ultrasonic sensor 73 senses the distance, and the visual sensor 74 obtains external environmental information, especially the visual positioning identification ring 83 arranged on the second pair of joints 8, so that the first pair of joints 7 and the second pair of joints 8 can be accurately docked. The permanent magnet 82 of the connector 8 is attracted by the magnetic force of the annular electromagnet 72 of the first pair of connectors 7, so the second pair of connectors 8 automatically docks with the first pair of connectors 7. In order to make the docking smoother, the first pair of connectors 7 is set to be conical, and the second pair of connectors 8 is correspondingly provided with a conical pit. After the docking is completed, the sliding push rod 71 presses the linkage lock 81 downward, so the linkage lock 81 drives one end of the transmission plate 85 through the offset fixed shaft 86, so the other end of the transmission plate 85 pushes the lock tongue 84 to be embedded in the annular lock groove 75 of the first pair of connectors 7, even if the power is cut off, the first pair of connectors 7 and the second pair of connectors 8 will not be disconnected. When the monitoring equipment needs to be deployed, the sliding push rod 71 is controlled to move upward, so the linkage lock 81 also moves upward, so the lock tongue 85 is moved out of the annular lock groove 75, and the unlocking is completed. Then the annular electromagnet 72 is powered off or generates a repulsive magnetic force to separate the first pair of connectors 7 from the second pair of connectors 8, and the monitoring equipment can be deployed by free fall. When encountering severe weather with strong winds, the posture of the mechanical rope can also be adjusted. If the monitoring equipment is set at an angle, the posture of the mechanical rope can also be adjusted to allow the first pair of connectors 7 and the second pair of connectors 8 to be docked.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
