Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dynamic detection instruments for water conservancy facilities, and in particular relates to water conservancy dam sluice pump monitoring equipment. Background Art
[0002] Water conservancy dam, gate, and pump monitoring equipment is used for high-precision monitoring of important water conservancy facilities such as dams, gates, and pumping stations. Its purpose is to ensure the operational safety and reliability of these facilities and to detect and prevent potential failures and risks through real-time monitoring.
[0003] Traditional dam monitoring equipment is mostly fixed or handheld, requiring manual operation and limiting its monitoring range and flexibility. In recent years, the rise of drone technology has revolutionized dam monitoring. Using drones to carry monitoring equipment is a modern, efficient, and flexible method for dam monitoring, enabling coverage over larger areas and accessing areas difficult to reach manually. However, to achieve high-precision monitoring, drones must hover during inspections and precisely adjust the monitoring equipment in multiple dimensions.
[0004] Although drones have shown many advantages in dam monitoring, existing technologies still have the following shortcomings: for example, when traditional drones are in a hovering state, the position and angle adjustment of the monitoring equipment are not precise enough, resulting in large errors in data collection; the installation and adjustment process of existing monitoring equipment on drones is complicated, making it difficult to achieve rapid response and real-time adjustment; and when the drone is hovering, the slight swing and resetting of the fuselage will affect the stability of the monitoring equipment, thereby affecting the quality of the monitoring data.
[0005] Existing drones still face challenges in achieving three-dimensional adjustment while hovering. For example, when adjusting the drone's vertical and horizontal movements, the fuselage can tilt and oscillate, affecting the stability of the monitoring equipment. This is because hovering relies on precise attitude control; any movement alters the drone's center of gravity and balance. Furthermore, when hovering, adjusting the horizontal and pitch angles relies on the drone's own attitude adjustments. However, the limited range of attitude adjustments available for drones makes it difficult to precisely adjust the monitoring equipment.
[0006] In order to improve the accuracy and efficiency of dam monitoring and solve the shortcomings of existing technologies, it is necessary to propose improvement plans. Utility Model Content

DETAILED DESCRIPTION
[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] Example 1: A water conservancy dam sluice pump monitoring device is mainly used for adjusting and monitoring the drone 1 in a hovering state through the airborne monitoring instrument 4. The monitoring device mainly includes the drone 1, a two-dimensional adjustment component 2, a transmission mechanism 3 and a monitoring instrument 4. Figure 1 and Figure 3 As shown, the UAV 1 includes a UAV outer frame 11, a central cross seat 12 and a cantilever 13. A central cross seat 12 is fixed laterally at the bottom center position of the UAV outer frame 11. Four rotor frames are respectively arranged on the peripheral edges of the main body of the UAV outer frame 11. Four cantilevers 13 are fixed to the main body of the UAV outer frame 11 from the center to the outside, and the four cantilevers 13 are distributed in a cross shape. Each cantilever 13 extends to the center position of the corresponding rotor frame, and an axis frame is fixed at the center of each rotor frame. A rotor motor is installed at the center of the axis frame, and a rotor is installed on the rotating shaft of the rotor motor. A two-dimensional adjustment component 2 is fixed on the lower surface or upper surface of the central cross seat 12, and a transmission mechanism 3 is installed on the two-dimensional adjustment component 2.
[0027] like Figure 2-Figure 6 As shown, the two-dimensional adjustment assembly 2 includes a column beam 21, a transverse slider 22, an auxiliary beam 23, a transverse sliding groove 24, and a longitudinal sliding groove 25. A transverse sliding groove 24 is provided in the center of the column beam 21, in which the transverse slider 22 is mounted. A longitudinal sliding groove 25 is provided in the longitudinal direction on the transverse slider 22, in which the auxiliary beam 23 is mounted.
[0028] like Figure 5 As shown, the transmission mechanism 3 includes a left drive wheel 31, a right drive wheel 32, an outer guide wheel 33, an inner guide wheel 34, a fixed end 35, and an endless belt 36. The left drive wheel 31 is mounted on the left end of the column beam 21, and the right drive wheel 32 is mounted on the right end. The outer guide wheel 33 is mounted on the front end of the auxiliary beam 23, and the fixed end 35 is fixed to the rear end. The inner guide wheels 34 are mounted on the surface of the cross slide 22, located outside the two sides of the auxiliary beam 23. The inner guide wheels 34 include an upper left guide wheel 341, an upper right guide wheel 342, a lower left guide wheel 343, and a lower right guide wheel 344. The leading and trailing ends of the endless belt 36 are respectively fixed within the fixed end 35 at the rear. The middle portion of the endless belt 36 is wound, from front to back, through the grooves of the lower left guide wheel 343, the left drive wheel 31, the upper left guide wheel 341, the outer guide wheel 33, the upper right guide wheel 342, the right drive wheel 32, and the lower right guide wheel 344. Supports are provided at the left and right ends of the column beam 21, with the left drive wheel 31 and the right drive wheel 32 respectively located within the corresponding support cavities. A left motor 37 and a right motor 38 are fixedly mounted on the outside of the supports. The rotating shaft of the left motor 37 is in driving connection with the rotating shaft of the left drive wheel 31, while the rotating shaft of the right motor 38 is in driving connection with the rotating shaft of the right drive wheel 32.
[0029] A base 41 is fixed on the outer surface of the middle portion of the auxiliary beam 23 , and a monitoring instrument 4 is fixed on the outer side of the base 41 .
[0030] The column beam 21 is located directly below the left and right rotors, and the auxiliary beam 23 is located directly below the front and rear rotors. The column beam 21 and the auxiliary beam 23 are respectively located below the cantilever 13 of each rotor shaft frame, and do not affect the airflow channel of each rotor.
[0031] Based on the above-described device, when the left and right motors 37, 38 rotate simultaneously and in the same direction, the entire auxiliary beam 23 moves rightward or leftward (when the left and right motors 37, 38 rotate counterclockwise, the auxiliary beam 23 and the monitoring instrument 4 move rightward, and when the left and right motors 37, 38 rotate clockwise, the auxiliary beam 23 and the monitoring instrument 4 move leftward), that is, the monitoring instrument 4 translates laterally in the left-right direction. When the left and right motors 37, 38 rotate simultaneously and in opposite directions, the entire auxiliary beam 23 moves forward or backward (when the left motor 37 rotates counterclockwise and the right motor 38 rotates clockwise, the auxiliary beam 23 and the monitoring instrument 4 move backward, and when the left motor 37 rotates clockwise and the right motor 38 rotates counterclockwise, the auxiliary beam 23 and the monitoring instrument 4 move forward), that is, the monitoring instrument 4 translates longitudinally in the front-back direction.
[0032] Monitoring instrument 4 can be any existing monitoring instrument, such as a total station, airborne lidar, real-time dynamic differential GPS system, or photogrammetry device. Dam structures are complex, and comprehensive observations from various angles are required during inspection to ensure that no potential hazards are missed. Horizontal angle adjustment (left-right rotation) and pitch adjustment (up-and-down tilt) allow the monitoring equipment to cover different inspection areas. Certain critical areas (such as cracks and leaks) require precise alignment for detailed inspection. By adjusting the angle of the monitoring equipment, it is possible to ensure that the equipment is facing the target, thereby improving inspection accuracy. Existing monitoring instruments, such as total stations, have inherent angular rotation capabilities. Alternatively, a rotating mechanism, such as a rotating motor, can be installed between monitoring instrument 4 and base 41. The rotating motor is controlled by a controller to control the vertical axial rotation of monitoring instrument 4. Alternatively, a clearance slot can be provided in the center of the main housing of monitoring instrument 4, with a transverse axis mounted transversely at the center of the clearance slot, and a tilting motor mounted on the transverse axis. A monitor is installed in the middle of the horizontal axis, and the flip motor is controlled by a controller so that the monitor can perform pitch angle flip adjustment along the horizontal axis.
[0033] When using the above-mentioned monitoring equipment, first prepare it by checking the status of the drone, ensuring that the battery is fully charged and that all rotors and motors are operating normally. Install the monitoring equipment (such as a total station, lidar, etc.) on the two-dimensional adjustment assembly to ensure that the equipment is firmly fixed. Ensure that all components of the transmission mechanism (drive wheels, guide wheels, belts, etc.) are installed correctly and can operate flexibly. Then, pre-set the areas and monitoring points to be monitored based on the specific conditions of the dam. Set the drone's flight altitude, speed, and hovering position to ensure that all areas that need to be monitored can be covered. Then control the drone's takeoff and hovering. Start the drone, make it take off smoothly, and fly to the pre-set monitoring position. Hover at the target monitoring position to ensure that the drone remains stable and provides a stable platform for the monitoring equipment.
[0034] During the inspection process, the monitoring device is adjusted laterally: The left and right motors are activated simultaneously, rotating them in the same direction. The lateral position of the auxiliary beam and monitoring device is adjusted as needed. When the left and right motors rotate counterclockwise, the monitoring device translates to the right; when they rotate clockwise, the monitoring device translates to the left. This lateral adjustment allows the monitoring device to cover different lateral locations within the target area, ensuring comprehensive coverage. Longitudinal Adjustment: The left and right motors are activated simultaneously, rotating them in opposite directions, adjusting the longitudinal position of the auxiliary beam and monitoring device as needed. When the left motor rotates counterclockwise and the right motor rotates clockwise, the monitoring device translates backward; when the two rotate in opposite directions, the monitoring device translates forward. This longitudinal adjustment allows the monitoring device to cover different longitudinal locations within the target area, ensuring comprehensive coverage. Angular Adjustment: Adjust the monitoring device's angle as needed. This can be achieved using the device's built-in rotation function or an installed rotation mechanism. The tilt motor controls the monitoring device's pitch angle to ensure it faces the target. This angle adjustment allows the monitoring device to observe from different angles, capturing detailed features of the target and improving monitoring accuracy. Data collection and recording: Start the equipment according to the monitoring task, collect data, record the collected data in real time, and transmit it wirelessly to the ground control station for storage and analysis.
[0035] Drone return and equipment maintenance: After completing the monitoring mission, control the drone to return to the starting position and land safely; inspect and maintain the drone and monitoring equipment to ensure that the equipment is in good condition the next time it is used. Through the above specific implementation steps, efficient and accurate monitoring can be achieved: using the drone hovering and two-dimensional adjustment components, the monitoring equipment can efficiently and accurately cover the target area and provide detailed monitoring data. Flexible adjustment: through the adjustment of the horizontal, longitudinal and plane angles, the monitoring equipment can flexibly respond to complex dam structures and ensure monitoring without blind spots. Real-time response: The motor-driven transmission mechanism can quickly respond to adjustment needs and improve monitoring efficiency. Data stability: The hovering state and stable platform ensure the stability of data acquisition of the monitoring equipment and improve data quality. Through these steps and effects, the utility model can significantly improve the technical level of water conservancy dam gate pump monitoring and provide strong guarantees for the safe operation of water conservancy facilities.
