Description

Technical Field

[0001] This utility model relates to the field of meteorological monitoring technology, and more specifically to a meteorological monitoring drone. Background Technology

[0002] In the field of meteorological monitoring, drones, due to their advantages such as flexibility, maneuverability, and ability to penetrate complex areas, have gradually become an important supplement to ground-based monitoring equipment and are widely used in collecting meteorological parameters such as atmospheric temperature, humidity, air pressure, wind speed, and wind direction. Currently, meteorological monitoring drones on the market typically consist of two parts: a flight carrier and onboard sensor units. The flight carrier provides lift and flight propulsion through rotor components, while the sensor units are fixedly installed in specific locations on the fuselage to complete meteorological data collection.

[0003] However, existing meteorological monitoring drones still have significant technical shortcomings in practical applications, which restrict the accuracy of monitoring data and the overall performance of the equipment. On the one hand, the sensor units of existing drones are often installed close to the rotor assembly, and their relative positions are fixed and cannot be adjusted according to flight conditions. Because the high-speed rotation of the rotor generates local airflow disturbances, airflow temperature changes, and mechanical vibrations, these disturbances directly affect the meteorological environment around the sensor unit. This leads to deviations between the temperature, humidity, air pressure, wind speed, and wind direction data collected by the sensors and the actual atmospheric environmental parameters. This problem is particularly prominent in scenarios requiring high monitoring accuracy, such as low altitudes and light winds, making it difficult to meet the needs of refined meteorological monitoring.

[0004] Therefore, how to provide a new type of meteorological monitoring drone that can avoid the interference of rotor rotation on sensor monitoring results and thus improve the accuracy of meteorological data collection is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a meteorological monitoring drone, which aims to solve the technical problem in the above-mentioned existing meteorological monitoring drones where the sensor is easily interfered with by rotor rotation, resulting in inaccurate monitoring data.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A weather monitoring drone includes:

[0008] A rack, which has a front end and a rear end arranged opposite each other;

[0009] The rotor assembly includes a left rotor assembly, a right rotor assembly, and a rear rotor assembly. The left rotor assembly includes a support tube, a first rotor, and a slide rod. The outer wall surface of the support tube near its first end is hinged to the frame along axis one. The first rotor is fixedly connected to the second end of the support tube. The rod surface of the slide rod is slidably connected to the inner tube surface of the support tube. The first end of the slide rod extends out of the outer side of the first end of the support tube. The right rotor assembly has the same structure as the left rotor assembly and is symmetrically arranged with the left rotor assembly along the center of the frame in the lateral direction. The rear rotor assembly is fixedly connected to the rear end of the frame.

[0010] The drive assembly includes an electric telescopic rod, a transmission block, and a mounting rod. The fixed end of the electric telescopic rod is fixedly connected to the frame. The transmission block is fixedly connected to the drive end of the electric telescopic rod and moves along the front-rear direction of the frame under the drive of the electric telescopic rod. The first end of the slide rod is hinged to the side of the transmission block along axis two. Both axis one and axis two are arranged parallel to the height direction of the frame. Axis one is located outside axis two and in front of axis two. The mounting rod is arranged along the front-rear direction of the frame and its first end is fixedly connected to the front end of the transmission block.

[0011] The sensor unit is detachably connected to the second end of the mounting rod.

[0012] Therefore, this utility model arranges the axis one of the support tube one, which is hinged to the frame, in the left rotor assembly outside and in front of the axis two of the slide rod one, which is hinged to the transmission block. When the drive end of the electric telescopic rod moves forward towards the frame, it will drive the transmission block fixed thereto to move forward synchronously, thereby pulling the first end of the slide rod one, which is hinged to the transmission block, to move forward. Since the slide rod one is slidably connected to the support tube one, the slide rod one will drive the support tube one to rotate around the axis two, causing the first rotor fixed to the support tube one to move backward towards the frame. At the same time, the mounting rod fixed to the front end of the transmission block will move forward with the transmission block, driving the sensor unit detachably connected to the second end of the mounting rod to move forward towards the frame, thereby keeping the sensor unit away from the interference of rotor rotation on the monitoring results, achieving the effect of improving monitoring accuracy and structural synergy.

[0013] Preferably, the rear rotor assembly includes a support tube three and a third rotor. The support tube three is arranged along the front-rear direction of the frame and its first end is fixedly connected to the frame. The third rotor is fixedly connected to the second end of the support tube three.

[0014] Preferably, the transmission block is slidably connected to the frame along the front-rear direction of the frame.

[0015] Preferably, the frame also includes a slide rail, which is arranged along the front-rear direction of the frame and fixedly connected to the frame, and the transmission block has a slide groove that is slidably connected to the slide rail.

[0016] Preferably, it also includes support legs, with three support legs, which are respectively arranged and fixedly connected to the rotors of the left rotor assembly, the right rotor assembly and the rear rotor assembly.

[0017] Preferably, it also includes a camera, which is fixedly connected to the bottom of the frame.

[0018] Preferably, it also includes an antenna module, which is fixedly connected to the frame.

[0019] Preferably, the sensor unit includes a temperature and humidity acquisition module, an air pressure acquisition module, and a wind speed and direction acquisition module.

[0020] Preferably, it also includes a controller, which is electrically connected to the control module of the electric telescopic pole, the camera, the antenna module, the temperature and humidity acquisition module, the air pressure acquisition module, and the wind speed and direction acquisition module.

[0021] Preferably, it also includes a battery, which is detachably connected to the bottom of the frame and connected to the controller via a wire to power the controller.

[0022] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a weather monitoring drone with the following beneficial effects: By driving the transmission block to move back and forth via an electric telescopic rod, the left and right rotors can be simultaneously rotated towards the rear of the frame, while simultaneously pushing the sensor unit to extend towards the front of the frame. This coordinated action of "rotor rearward movement + sensor forward extension" can significantly increase the distance between the sensor and the rotor, effectively avoiding local airflow disturbances, temperature changes, and mechanical vibrations caused by the high-speed rotation of the rotor. This ensures that the temperature, humidity, and air pressure data collected by the sensor are closer to the real atmospheric environment, making it particularly suitable for scenarios with high monitoring accuracy requirements, such as low altitude and light winds.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. See the appendix. Figure 1 To be continued Figure 4 This utility model discloses a weather monitoring drone, including: a frame 1, a rotor assembly, a drive assembly 3, and a sensor unit 4;

[0034] The rack 1 has a front end and a rear end arranged opposite to each other;

[0035] The rotor assembly includes a left rotor assembly 21, a right rotor assembly 22, and a rear rotor assembly 23. The left rotor assembly 21 includes a support tube 211, a first rotor 212, and a slide bar 213. The outer wall surface of the support tube 211 near its first end is hinged to the frame 1 along the axis. The first rotor 212 is fixedly connected to the second end of the support tube 211. The rod surface of the slide bar 213 is slidably connected to the inner tube surface of the support tube 211. The first end of the slide bar 213 extends out of the outer side of the first end of the support tube 211. The right rotor assembly 22 has the same structure as the left rotor assembly 21 and is symmetrically arranged with the left rotor assembly 21 along the center of the frame 1 in the lateral direction. The rear rotor assembly 23 is fixedly connected to the rear end of the frame 1.

[0036] The drive assembly 3 includes an electric telescopic rod 31, a transmission block 32, and a mounting rod 33. The fixed end of the electric telescopic rod 31 is fixedly connected to the frame 1. The transmission block 32 is fixedly connected to the drive end of the electric telescopic rod 31 and moves along the front-rear direction of the frame 1 under the drive of the electric telescopic rod 31. The first end of the slide rod 213 is hinged to the side of the transmission block 32 along axis 2. Both axis 1 and axis 2 are arranged parallel to the height direction of the frame 1. Axis 1 is located outside axis 2 and in front of axis 2. The mounting rod 33 is arranged along the front-rear direction of the frame 1 and its first end is fixedly connected to the front end of the transmission block 32.

[0037] The sensor unit 4 is detachably connected to the second end of the mounting rod 33.

[0038] Specifically, the right rotor assembly 22 includes a second support tube 221, a second rotor 222, and a second slide bar 223, which are arranged symmetrically with the first support tube 211, the first rotor 212, and the first slide bar 213 along the side of the frame 1.

[0039] Specifically, the frame 1 includes an upper mounting plate 12 and a lower mounting plate 13 arranged in parallel, and the drive assembly 3, support tube 1 211, slide rod 1 213, support tube 2 221 and slide rod 2 223 are all located between the upper mounting plate 12 and the lower mounting plate 13.

[0040] More specifically, the left rotor assembly 21 also includes a rotating seat 214, which is hinged along the axis to the opposite surfaces of the upper mounting plate 12 and the lower mounting plate 13. The support tube 211 is fixedly connected to the rotating seat 214. The rotating seat 214 has a clearance hole at the pipe opening position corresponding to the first end of the support tube 211. The slide rod 213 passes through the clearance hole and is slidably connected to the inner tube surface of the support tube 211.

[0041] Specifically, the right rotor assembly 22 also includes a second rotating base 224, which has the same structure as the first rotating base 214 and is arranged symmetrically along the side of the frame 1.

[0042] In some embodiments, the rear rotor assembly 23 includes a support tube 231 and a third rotor 232. The support tube 231 is arranged along the front-rear direction of the frame 1 and its first end is fixedly connected to the frame 1. The third rotor 232 is fixedly connected to the second end of the support tube 231.

[0043] See appendix Figure 5 and attached Figure 6 The transmission block 32 is slidably connected to the frame 1 along the front-back direction of the frame 1.

[0044] In this embodiment, the frame 1 also includes a slide rail 11, which is arranged along the front-rear direction of the frame 1 and fixedly connected to the frame 1. The transmission block 32 has a groove that is slidably connected to the slide rail 11. Thus, the slide rail 11 is fixedly arranged along the front-rear direction of the frame 1, and the transmission block 32 precisely cooperates with the slide rail 11 through the groove to form a clear and fixed movement path, completely eliminating the up-down and left-right deviation of the transmission block 32 during the movement. Even under the condition of turbulence during the flight of the UAV, the stability of the movement of the transmission block 32 can be guaranteed, ensuring the precise execution of the adjustment of the left rotor assembly 21 and the right rotor assembly 22 and the movement of the sensor unit 4.

[0045] Specifically, there are four slide rails 11, which are fixedly connected to the opposite surfaces of the upper mounting plate 12 and the lower mounting plate 13 in pairs. The two slide rails 11 in each pair are arranged symmetrically along the center of the frame 1. The transmission block 32 has four grooves that correspond to the four guide rails.

[0046] See appendix Figure 2 It also includes support legs 5, of which there are three, which are respectively arranged and fixedly connected to the rotors corresponding to the left rotor assembly 21, the right rotor assembly 22 and the rear rotor assembly 23.

[0047] This embodiment also includes a camera 6, which is fixedly connected to the bottom of the frame 1. Thus, the camera 6 can transmit ground images in real time, helping operators observe the surrounding environment of the drone and avoid obstacles such as trees and buildings in a timely manner, ensuring flight safety. Simultaneously, visual images allow for advance planning of monitoring routes, ensuring that the sensor unit 4 can cover key monitoring areas, improving the efficiency and targeting of meteorological monitoring tasks.

[0048] Specifically, the lowest point of the support leg 5 along the height direction of the frame 1 is lower than the lowest point of the camera 6 along the height direction of the frame 1.

[0049] Specifically, both support tube 1 (211) and support tube 2 (221) have two working positions: a flight working position and a testing working position. When in the flight working position, the included angle between the axes of support tube 1 (211) and support tube 2 (221) is 120°. When in the testing working position, support tube 1 (211) and support tube 2 (221) are arranged coaxially.

[0050] More specifically, it also includes clamps 14, of which there are two clamps 14, with their openings facing the rear of the frame 1, to clamp the support tube 1 211 and the support tube 221 when they are in the flight working position.

[0051] In some embodiments, the system also includes an antenna module 7, which is fixedly connected to the frame 1. Thus, the signal enhancement function of the antenna module 7 can extend the remote control distance and data transmission distance of the UAV, enabling the UAV to operate in more distant monitoring areas such as remote mountainous regions and the sea, breaking through the limitations of traditional short-range meteorological monitoring and expanding the coverage of meteorological monitoring.

[0052] In other embodiments, sensor unit 4 includes a temperature and humidity acquisition module, an air pressure acquisition module, and a wind speed and direction acquisition module. Thus, temperature, humidity, air pressure, and wind speed and direction are core basic parameters for meteorological monitoring. Simultaneous acquisition of these three parameters forms a complete atmospheric environment data chain, avoiding the limitations of single-parameter monitoring and providing a more comprehensive reflection of the meteorological conditions in the monitored area. This provides more accurate and comprehensive data for weather forecasting, climate analysis, and disaster early warning such as typhoon and rainstorm warnings.

[0053] In this embodiment, a controller is also included. The controller is electrically connected to the control modules of the first rotor 212, the second rotor 222, the third rotor 232, the electric telescopic rod 31, the camera 6, the antenna module 7, the temperature and humidity acquisition module, the air pressure acquisition module, and the wind speed and direction acquisition module.

[0054] In some other specific embodiments, a battery 8 is also included, which is detachably connected to the bottom of the frame 1 and connected to the controller via a wire to supply power to the controller.

[0055] The specific principle and usage method of a meteorological monitoring drone provided in this embodiment are as follows:

[0056] The ground terminal sends a "takeoff command", the controller drives the three rotors to start, and the UAV ascends vertically to the preset initial altitude; at this time, the left rotor assembly 21 and the right rotor assembly 22 are in the "flight working position", and the clamp 14 on the frame 1 clamps the support tubes one and two to ensure the stability of the rotor attitude during flight.

[0057] After the UAV reaches its initial altitude, the ground terminal sends a "sensor extend command". The controller controls the drive end of the electric telescopic rod 31 to extend forward, driving the transmission block 32, the mounting rod 33 and the sensor unit 4 to move forward. At the same time, the left and right rotors rotate backward synchronously until the sensor unit is fully extended (at this time, the left and right rotors are in the "detection working position" and the monitoring attitude adjustment is completed).

[0058] After completing the monitoring task, the ground terminal sends a "sensor retrieval command". The controller controls the drive end of the electric telescopic rod 31 to retract backward, and the transmission block 32 drives the sensor unit 4 back to the vicinity of the frame 1. At the same time, the left and right rotors rotate forward to return to the "flight working position", and the clamp 14 re-clamps the support pipes one and two.

[0059] Sending a "return command" causes the drone to return along the original or optimal path. Once it reaches the airspace above the take-off and landing point, the controller reduces the rotation speed of each rotor, causing the drone to land vertically. After the support leg 5 touches the ground, the rotor power is shut off.

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
