Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a floating rod for UAVs. Background Technology

[0002] Currently used drone floating devices generally have many components and are heavy, increasing the drone's load. Furthermore, some floating devices have complex structures and are cumbersome to assemble. The main floats of these devices often lack a streamlined shape, resulting in high drag and affecting the drone's endurance, thus hindering the promotion and application of drone floating devices. It is also common for drone owners to fly their drones over rivers and lakes; if a drone falls into the water, it will cause property damage. Utility Model Content

[0003] The purpose of this utility model is to provide a floating rod for unmanned aerial vehicles (UAVs). Its main components include: 1. a streamlined floating rod, 2. a riser and locking device.

[0004] The streamlined float is a low-density, high-strength closed-cell foam rod with a streamlined shape and a riser insertion hole at the front of the center of gravity.

[0005] The riser and locking device consist of a thin-walled pipe section and a locking ring and locking screw attached to the pipe. The locking ring is a cylindrical pipe clamp, and the locking screw has a conical head. It is connected to the cylindrical pipe clamp by threads, passes inward through the riser wall, and pierces the column below the drone's forearm motor.

[0006] The locking ring on the riser is fitted over the riser and has a locking screw; two circular rubber bands are fixed at the bottom of the riser.

[0007] Furthermore, the locking ring, locking screw, rubber band, and riser attached to the riser together form a whole.

[0008] Furthermore, the lower part of the riser is inserted into the riser insertion hole of the float rod, and a rubber band is used to secure it to the float rod, thus firmly installing the riser on the float rod; the upper part of the riser is fitted onto the column below the motor of the drone's forearm. The rear part of the float rod is tied to the neck of the drone's rear arm with a rubber band, forming a floating device on one side of the drone.

[0009] Furthermore, using the same method described above, install a floating device on the other side of the drone.

[0010] Further adjustments to the symmetrical positions of the floats on the left and right sides of the drone, and proper tightening of the locking screws on the two vertical pipes, complete the entire solution.

[0011] This utility model has a simple structure with only two sets of components. After the initial installation, subsequent installations and disassemblies can be completed in just a few seconds.

[0012] This device weighs only 54 grams and has a streamlined float, providing high buoyancy and low drag, making it suitable for various drones. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments.

[0019] Example 1

[0020] like Figures 1 to 3 As shown: A floating rod for unmanned aerial vehicles, the main structure of which includes: a floating rod (1), a riser insertion hole (2), a riser (3), a locking ring (4), a locking screw (5), and a rubber band (6) fixedly installed on the riser.

[0021] The float (1) is a low-density, high-strength closed-cell foam rod with a streamlined shape. There is a riser insertion hole (2) at the front of the center of gravity of the rod. The riser insertion hole (2) is not a through hole.

[0022] The riser (3) is a thin-walled, low-density, high-strength, and tough plastic pipe.

[0023] The locking ring (4) is a cylindrical pipe clamp made of ABC material, with a locking screw at the center of the side of the clamp. The locking ring (4) is securely installed about 2 cm below the top of the riser (3).

[0024] The locking screw (5) is a 304 stainless steel hexagonal cone-shaped pointed screw, which is installed on one side of the locking ring and connected to the locking ring by threads. The cone tip passes through the upright tube and pierces into the column under the front arm motor of the UAV, locking the float (1) and the upright tube (3) to the UAV.

[0025] The rubber band (6) fixedly installed on the riser (3) is used to fix the riser (3) to the float (1).

[0026] The following steps outline the implementation of this utility model:

[0027] First, based on the distance from the center of gravity of the UAV to the midpoint of the line connecting the forearm motor shaft, and the weight of the locking ring (4) and rubber band (6) on the riser (3), determine and calculate the position for drilling the riser insertion hole (2) on the float (1), and then drill the hole. Ensure that the center of gravity of this utility model coincides with the center of gravity of the UAV;

[0028] The second step is to securely install the locking ring (4) about 2 cm below the top of the plastic riser (3) and install the locking screw (5) on the locking ring (4);

[0029] The third step is to drill a hole about 4 cm above the end of the riser (3). The hole passes through the front and rear walls of the riser (3), and the central axis of the two holes is perpendicular to the axis of the locking screw (5) above it.

[0030] The fourth step is to pass the two rubber bands (6) that are connected end to end through the holes in the front and rear pipe walls of the riser (3), leaving the connection point of the two rubber bands (6) inside the riser (3).

[0031] Fifth step, insert the lower part of the riser (3) into the riser insertion hole (2) of the float (1), inserting it to such a depth that the hole penetrating the front and rear walls of the riser is close to the upper surface of the float, and make the center line of the two holes parallel to the longitudinal axis of the float. Put the two rubber bands (6) around the float from the front and back, and tie and fix the riser (3) to the float (1);

[0032] Step 6: Insert the column under the motor on one side of the drone's forearm into the riser tube (3);

[0033] Step 7: Use a separate rubber band to tie the rear part of the float on one side of the drone to the neck of the end of the drone's rear arm. This connects the six components—the riser (3), locking ring (4), locking screw (5), float (1), and the front and rear arms on one side of the drone—to form a single unit.

[0034] Step 8: Using the same method, install the aforementioned device on the other side of the drone;

[0035] Step 9: Adjust the angle between the longitudinal axis of the float and the central axis of the drone to ensure that the floats on both sides are symmetrical about the central axis of the drone. Tighten the two locking screws (5) to make the drone and all the components of this utility model tightly connected together.

[0036] When this device needs to be disassembled, simply remove the rubber band on the rear arm of the drone, loosen the two locking screws (5) on the left and right, and the device can be quickly and easily removed in a few seconds. When it needs to be reinstalled, simply insert the column under the motor of the drone's front arm into the vertical tube (3), tie and fix the rear part of the float (1) to the neck of the drone's rear arm, and tighten the locking screws (5) appropriately.

[0037] This utility model has a simple structure with only two sets of components. After the initial installation, subsequent installations and removals can be completed in just a few seconds.

[0038] This device weighs only 54 grams, features a streamlined float, provides high buoyancy on water, and minimizes drag, making it suitable for various drone models. Drones using this technology can take off and land safely on water, ensuring the safety of the owner's property.
