Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) pod technology, and in particular to an anti-sway and vibration-damping pod mounted on a flow meter UAV. Background Technology

[0002] In fields such as hydrological monitoring, water conservancy engineering surveying, and environmental monitoring, the use of drones equipped with current meters for water velocity measurement has become a mainstream technical method. Compared with the traditional method of manually deploying current meters, the drone-mounted measurement mode has advantages such as high mobility, high operational efficiency, and outstanding adaptability to complex terrain. It can quickly complete the collection of flow velocity data over large areas of water, providing accurate data support for water resource management and flood control and disaster reduction.

[0003] During flight, the drone's airframe experiences continuous vibration due to factors such as high-speed propeller rotation and airflow disturbances. Furthermore, during takeoff, landing, turning, or encountering sudden turbulence, relative swaying can easily occur between the airframe and its mounted components. As a precision measuring device, the current meter demands extremely high installation stability for its measurement accuracy. However, existing connections between drones and current meter pods rely solely on simple bolt rigid fixation, lacking specialized anti-sway and vibration-damping designs. This results in the drone's vibrations being directly transmitted to the current meter pod, interfering with the normal operation of the current meter's internal sensing elements, reducing the accuracy of measurement data, and causing fatigue damage at the connection points between the pod and the airframe. Prolonged vibration and swaying can lead to loosening of the bolts at the connection points, and in severe cases, even separation of the current meter pod from the drone airframe, causing equipment falls and damage, interruption of measurement missions, and other safety accidents, increasing operating costs and safety risks.

[0004] Therefore, this utility model provides an anti-sway and vibration-damping pod for a flow meter drone. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an anti-sway and vibration-damping pod for a flow meter drone.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an anti-sway and vibration-damping pod mounted on a flow meter UAV, comprising:

[0008] A flow meter pod, wherein the flow meter pod is installed at the bottom of the unmanned aerial vehicle;

[0009] An anti-sway and vibration damping component is disposed at the bottom of the drone body. The anti-sway and vibration damping component includes an annular frame, the top of which is fixedly connected to the bottom of the drone body. An annular block is engaged with the inner wall of the annular frame. A circular frame is fixedly connected to the bottom of the annular block. A connecting rod is fixedly connected to the bottom of the circular frame. A rubber block is placed on the top of the circular frame and disposed inside the annular block.

A rotating block is fixedly connected to the outer surface of the rotating rod, and the outer surface of the rotating block is fixedly connected to the flow meter pod.

[0011] With the help of the anti-sway and vibration damping components, the connection between the circular frame and the UAV body is damped by the rubber blocks. At the same time, the support rods and circular plates make the support of the connecting rods and other components more stable, thereby preventing the flow meter pod from swaying. With the help of the adjustment components, the angle of the flow meter pod can be adjusted.

[0012] Optionally, the inner wall of the annular card frame is provided with a circular insertion hole, and a circular insertion rod is fixedly connected to the top of the annular card block, the circular insertion rod being inserted into the inner wall of the circular insertion hole.

[0014] Optionally, an annular plate is fixedly connected to the top of the circular frame, a first screw hole is provided on the top of the annular plate, a second screw hole is provided on the bottom of the unmanned aerial vehicle body, and a first threaded clamp is threadedly connected to the inner wall of the first screw hole and the second screw hole.

[0015] The first threaded clamp is fixed to the first and second threaded holes, thereby fixing the annular plate to the unmanned aerial vehicle body.

[0017] Support rods can provide auxiliary support for components such as connecting rods, thereby effectively preventing swaying.

[0018] Optionally, a third screw hole is provided at the top of the second rectangular block, and a fourth screw hole is provided at the bottom of the circular frame. The inner walls of the third screw hole and the fourth screw hole are threadedly connected to a second threaded rod.

[0019] The second threaded clamp is fixed to the third and fourth threaded holes, which can fix the second rectangular block to the circular frame.

[0020] Optionally, one end of the rotating rod is fixedly connected to an operating block, and one side of the operating block is threadedly connected to a third threaded clamp.

[0021] The third threaded lever can move along the inner wall of the operating block, thereby cooperating with other components for fixation.

[0022] Optionally, a plurality of threaded locking holes are provided on one side of the U-shaped plate, and the plurality of threaded locking holes are equidistantly arranged along the rotating rod, and the third threaded locking rod is threadedly adapted to the threaded locking holes.

[0023] The threaded locking hole fixes the third threaded locking rod to the threaded locking rod, thereby fixing the rotating rod.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] With the anti-sway and vibration damping components, the rubber block can be installed using a ring-shaped clip and ring-shaped block. This allows the rubber block to dampen the vibration of the drone body and connecting rods. Simultaneously, the supporting rods provide auxiliary support and fixation for the connecting rods, thus preventing significant errors in the flow meter caused by vibrations of the connecting rods and the drone. The adjustment components allow for adjustment of the flow meter pod angle, adapting to actual flow velocity measurement needs and improving overall adaptability. Attached Figure Description
