Description

Technical Field

[0001] The present invention relates to the technical field of water rescue drones, and particularly to a water rescue drone and a life buoy carrying device thereof. Background Art

[0002] Water rescue is an emergency rescue operation carried out for various sudden dangerous situations in water environments, covering rivers, lakes, oceans and various artificial water areas. The challenges it faces are extremely complex. Factors such as rapid water flow, unpredictable water levels, large water temperature differences and unknown underwater conditions all increase the difficulty of rescue significantly. Rescue personnel not only need to have excellent swimming skills, but also be proficient in the use of various professional rescue equipment, such as watercraft like inflatable boats and rubber boats, as well as life-saving equipment such as throwers and life ropes. In the rescue process, teamwork is crucial, and all links from information collection, on-site command to actual rescue operations are closely connected. Common rescue methods include direct water entry rescue, where rescue personnel approach the trapped person wearing professional protective equipment; rapid transfer using boats to move the trapped person from the dangerous area to a safe place; in addition, onshore support and cooperation are also indispensable, such as setting up safety ropes and conducting lookout observations. Water rescue requires the rescue team to have a high degree of professionalism, rapid response ability and good physical fitness to handle emergencies that may occur at any time and maximize the protection of people's lives and property safety.

[0003] Most of the existing water rescue drones adopt the scheme of suspending life buoys with ropes. Due to the limited suspension capacity, problems such as untimely rescue may occur during large-scale rescues. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a water rescue drone and a life buoy carrying device thereof, which solve the problem that most of the existing water rescue drones adopt the scheme of suspending life buoys with ropes. Due to the limited suspension capacity, problems such as untimely rescue may occur during large-scale rescues.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A lifebuoy carrying device for a water rescue drone, including a loading bucket. A compressed lifebuoy is arranged inside the loading bucket. The interior of the loading bucket is a hollow structure. A throwing opening is provided at the front top of the loading bucket. A slideway is provided on the outer wall of the loading bucket. A limiting groove is provided at a position near the rear of the outer wall of the loading bucket. The slideway and the limiting groove are interconnected. A push plate is arranged at the rear of the compressed lifebuoy. A slider is arranged on the outer wall of the push plate. The slider is located inside the limiting groove and the slideway. The rear of the push plate is fixedly connected to one end of a first spring. The other end of the first spring is fixedly connected to the inner wall of the loading bucket. A driving device is arranged at the front end of the compressed lifebuoy. A rotating shaft is fixedly arranged at the output end of the driving device. A flap is fixedly connected to the outer wall of the rotating shaft.

[0006] Preferably, the driving device includes a first motor. The outer wall of the first motor is fixedly connected to the first motor.

[0007] Preferably, an installation seat is arranged on the outer wall of the loading bucket. A limiting hole is provided on the outer wall of the installation seat.

[0008] A water rescue drone, including a fuselage. A pan-tilt is fixedly arranged at the bottom of the fuselage. A camera is arranged at the bottom of the pan-tilt.

[0009] Preferably, one end of a support arm is fixedly connected to the side wall of the fuselage. The other end of the support arm is fixedly connected to the outer wall of a second motor. A transmission shaft is fixedly arranged at the output end of the second motor. A propeller is fixedly arranged on the outer wall of the transmission shaft.

[0010] Preferably, a support leg is fixedly arranged at the top of the fuselage. A convex block is arranged at the bottom of the support leg. One end of a second spring is fixedly connected to the rear of the convex block. The other end of the second spring is fixedly connected to the inside of an installation groove. The bottom of the installation groove is fixedly connected to the inner wall of the support leg.

[0011] Preferably, the support leg is located inside the installation seat. The convex block is located inside the limiting hole.

[0012] Preferably, a controller is arranged inside the fuselage. The controller is electrically connected to the first motor through an electric wire. The camera is electrically connected to the controller through an electric wire.

[0013] Working principle: Arrange the compressed lifebuoy into a disc shape, then pull the slider to the end of the slideway, and then rotate the slider counterclockwise to lock the slider inside the limit groove. Then put the arranged compressed lifebuoy into the loading bucket from the feeding port for filling. After filling, turn the slider clockwise to make the first spring push the push plate forward, thereby squeezing the compressed lifebuoy. The controller sends a signal to the second motor through the wire, and the second motor outputs a rotational force, which makes the transmission shaft drive the paddle to rotate, so as to move. Then drive the camera through the cloud platform to take large-area photos. Identify the number and specific location of the drowning people through the camera, and transmit the information to the controller through the wire. After receiving the information transmitted by the camera, the controller controls the second motor to output a rotational force, and then accurately move above the rescue personnel. When throwing, the controller sends a signal to the first motor through the wire, and the first motor outputs a rotational force, which makes the rotating shaft drive the flap to rotate, and the compressed lifebuoy is pushed out from the feeding port through the flap to throw the compressed lifebuoy to the person to be rescued.

[0014] The present invention provides a water rescue drone and its lifebuoy carrying device. It has the following beneficial effects:

[0015] 1. In the present invention, multiple compressed lifebuoys can be placed inside the loading bucket. The first spring can always push the compressed lifebuoy towards the feeding port, and then the first motor outputs a rotational force, and the multiple compressed lifebuoys are thrown out from the feeding port through the flap, thus improving the existing water rescue drone which mostly adopts the scheme of suspending the lifebuoy by a rope. Due to the limited suspension capacity, the problem of untimely rescue may occur during large-scale rescue.

[0016] 2. In the present invention, while the loading bucket loads the compressed lifebuoy, it can play a role in providing buoyancy. When the drone fails, it can float on the water surface through the loading bucket, thus preventing the drone from sinking to the bottom.

[0017] 3. In the present invention, the convex block arranged inside the leg can be engaged inside the limit hole on the outer wall of the mounting seat. By pressing the convex block, the leg can be quickly removed from the mounting seat, so that the loading bucket can be quickly installed. When a large number of rescues are needed, multiple loading buckets can be prepared in advance, and the loading bucket can be quickly disassembled and assembled when the drone flies back, thus improving the rescue efficiency.
