Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle for river inspection. Background Art
[0002] River patrol is an activity to monitor and assess river conditions, aimed at ensuring the normal operation of rivers, preventing floods, protecting the ecological environment, and maintaining the sustainable use of water resources.
[0003] Currently, river inspections are mostly carried out using drones, which are controlled to fly over the river and use image processing equipment to inspect the river conditions. However, existing river inspection drones can only perform simple image transmission and recording, which is inconvenient for cleaning garbage and other debris in the river, and requires subsequent processing, which has low efficiency.
[0004] Therefore, a multi-rotor drone for river patrol has been developed that can use drones to search the river and clean up garbage and other debris in the river at the same time. Utility Model Content

[0006] The technical solution of the utility model is: a multi-rotor UAV for river inspection, comprising a fuselage, a long arm, a blade, a swivel seat, a ball joint, a splint, a landing gear and a floating stop mechanism, the long arms are connected to the left and right sides of the fuselage, the blades are rotatably connected to the long arms, the lower left side of the fuselage is rotatably connected to the swivel seat, the right side of the swivel seat is connected to the ball joint, the right side of the ball joint is connected to the splint, the lower left sides of the left and right sides of the fuselage are connected to the landing gear, and the lower front and rear sides of the fuselage are provided with the floating stop mechanism for floating on the water surface.
[0007] Furthermore, the floating mechanism includes a wide bar, an airbag, a high-pressure gas cylinder, a floating ball and an electric contact.

The left and right parts of the wide bar are slidably connected to the floating balls, and the upper parts of the floating balls are connected to the electric contacts. The high-pressure gas cylinders are electrically connected to adjacent electric contacts, and the electric contacts are squeezed and matched with the fuselage. When the fuselage descends and contacts the water surface, the buoyancy of the water lifts the floating ball upward, and the floating ball moves upward to drive the electric contact to move upward. The electric contact moves upward and contacts the fuselage, triggering the high-pressure gas cylinder, so that the high-pressure gas cylinder injects gas into the airbag, causing the airbag to expand, increase the buoyancy of the fuselage, and make the fuselage float on the water surface to prevent the fuselage from falling into the water and being damaged.
[0008] Furthermore, a buffer mechanism is included, which includes an elastic member, a telescopic rod and a support foot. The bottom of the long arm is slidably connected to the telescopic rod, the top of the telescopic rod is connected to the adjacent long arm with an elastic member, and the bottom of the telescopic rod is connected to the support foot. When the fuselage lands, the support foot contacts the ground and squeezes the telescopic rod, so that the telescopic rod moves and compresses the elastic member, and the elasticity of the elastic member is combined to buffer the impact force of the fuselage when it descends.
[0009] Furthermore, a camera is provided at the bottom of the fuselage.
[0010] Furthermore, the elastic member is the spring.
[0011] Furthermore, it also includes a protective cover, and the upper part of the long arm is connected to the protective cover.

While using a drone to search the river channel, it is convenient to use the drone to clean up garbage and other debris in the river channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] When the utility model is in use, the fuselage 1 is remotely controlled to fly to a river channel that needs to be inspected, the blades 3 rotate at high speed to provide lift to the fuselage 1, and cooperate with each other to control the flight attitude and direction of the fuselage 1. When the fuselage 1 is inspected over the river channel and garbage in the river channel needs to be cleaned, the rotating seat 4 is remotely controlled to rotate, and the ball joint 5 supports the clamping plate 6, so that the clamping plate 6 can be rotated and adjusted at multiple angles, and the clamping plate 6 is used to clean garbage and other debris in the river channel. When the fuselage 1 descends and contacts the water surface, the buoyancy of the water lifts the floating ball 84 upward, and the floating ball 84 moves upward to drive the electric contact 85 to The electrical contact 85 moves upward and contacts the fuselage 1, triggering the high-pressure gas cylinder 83, so that the high-pressure gas cylinder 83 injects gas into the airbag 82, so that the airbag 82 expands, increases the buoyancy of the fuselage 1, and makes the fuselage 1 float on the water surface to prevent the fuselage 1 from falling into the water and being damaged. When the fuselage 1 completes the landing, the supporting foot 93 contacts the ground and squeezes the telescopic rod 92, so that the telescopic rod 92 moves and compresses the spring 91, and cooperates with the elasticity of the spring 91 to buffer the impact force of the fuselage 1 when it descends, until the landing gear 7 is in stable contact with the ground, and the landing operation of the fuselage 1 is completed.
