Description

Technical Field

[0001] The invention relates to the technical field of water rescue equipment, in particular to a water life buoy launching device. Background Art

[0002] The lifebuoy is a common water rescue equipment and plays an important role in the rescue of drowning people. In the past, when rescuing people who fell into the water, the lifebuoy was usually thrown manually by rescue workers. The manual throwing distance is limited and the throwing accuracy is often not effectively controlled. The landing point of the lifebuoy is likely to deviate from the position of the drowning person. Once the lifebuoy is thrown off, it must be pulled back and thrown again.

[0003] With the improvement of drone's carrying capacity, drones are also used in the field of water rescue. Drones can carry lifebuoys and drop them into the water when they fly to the person who falls into the water, thus ensuring the throwing accuracy and having a longer throwing distance.

[0004] However, there are some problems in the use of the existing water lifebuoy delivery equipment based on load-bearing drones. First, when the existing load-bearing drones deliver lifebuoys, they generally use inflated lifebuoys. The inflated lifebuoys are large in size and have greater air resistance during flight, which not only affects the flight efficiency and flight stability, but also limits the number of lifebuoys that can be stored. In order to prevent the inflatable lifebuoy from affecting the flight stability and speed of the drone and ensure the rescue efficiency, a water lifebuoy delivery equipment is proposed, which is equipped with an electric clamping structure that can be clamped and connected with the common load-bearing drone chassis, so that it can be easily disassembled and assembled. At the same time, it has good applicability and can be applied to most common load-bearing drones on the market. It can be loaded with multiple automatic inflatable lifebuoys and can be stably dropped onto the water surface for life-saving operations. The automatic inflatable lifebuoy is provided with an inflation port, and a one-way valve and a gas cylinder are provided at the inflation port. When the automatic inflatable lifebuoy is used, after the automatic inflation device comes into contact with water, the puncture needle punctures the bottle mouth of the gas cylinder, thereby releasing the compressed gas in the gas cylinder, and then quickly completes the inflation of the life-saving airbag. The equipment bracket is a rectangular frame structure, which is convenient for the drone gimbal monitoring camera to observe the delivery position, thereby having better delivery accuracy. Summary of the invention

[0005] The present invention provides an aquatic life buoy delivery device, which solves the problems raised in the above-mentioned background technology. A plurality of foldable and retractable automatic inflatable life buoys can be configured for lifesaving work, thereby preventing the life buoys from affecting the flight stability and speed of a drone. The device as a whole is easy to disassemble and install, and can be used for the rapid rescue of a single person who falls into the water, and can also be used for aquatic lifesaving work of multiple people who fall into the water. The device has good applicability. The device is loaded and transported by a drone, hoisted and dropped by a steel wire rope, and pushed and delivered by an electric telescopic rod, so that the folded automatic inflatable life buoy can fall around the person who falls into the water as much as possible or even at hand.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, a non-slip rubber pad is provided at the groove of the positioning hook, so that the positioning hook can be stably positioned at the landing gear of the drone body, so that the drone can drive the delivery equipment to move.

[0009] Furthermore, the equipment bracket is evenly provided with strip holes, and the No. 1 mounting frame is provided with bolt holes corresponding to the strip holes, so that the loading cylinder can be evenly installed on the equipment bracket through threads, and the installation quantity can be selected according to needs.

[0010] Furthermore, the equipment bracket is a rectangular frame structure, and the drone body is provided with a gimbal monitoring camera. Such an equipment structure facilitates the drone to photograph the water surface environment through the gimbal monitoring camera, thereby helping the operator to accurately locate and release the person who falls into the water.

[0011] Furthermore, the No. 2 mounting frame is threadedly connected with a positioning screw, and the positioning screw is rotatably connected with a clamping positioning plate. Rotating the positioning screw can drive the clamping positioning plate to slide in the No. 2 mounting frame, and the clamping positioning plate can clamp the landing gear of the UAV body with the No. 2 mounting frame, so that the UAV can carry a single loading barrel to quickly carry out a single water lifebuoy delivery and rescue operation.

[0014] Furthermore, a plurality of the loading cylinders are symmetrically arranged at the equipment bracket, which can prevent the uneven load-bearing of the drone body from affecting the stability of the flight process.

[0015] The beneficial effects of the present invention are as follows: the present invention provides a water life buoy delivery device, which has the following advantages:

[0016] 1. Start the No. 1 brake stepper motor to drive the positioning hook to move. The positioning hooks on both sides can clamp and position the landing gear of the drone body. Remove the protective tube cover to start the delivery operation. This installation structure is suitable for most drone bodies with rod-type landing gears, and has good substitutability and applicability. After the automatic inflatable lifebuoy of a set of equipment brackets is delivered, a new equipment bracket can be quickly replaced and installed on the landing gear of the drone body. The drone body can fly again for the second water lifebuoy delivery operation. The used equipment bracket can be loaded with a new automatic inflatable lifebuoy for standby, thereby achieving better water rescue efficiency;

[0017] 2. The main body of the drone can drive the equipment bracket and the loading cylinder installed on it to fly to the person who falls into the water. The equipment bracket is a frame structure. The monitoring gimbal of the main body of the drone is convenient for video monitoring of the bottom, so that the loading cylinder can automatically release the inflatable lifebuoy corresponding to the person who falls into the water at the bottom.

The wire rope can drive the release cylinder to steadily descend to the top of the person who falls into the water, so that the automatic inflatable lifebuoy can be as close to the person who falls into the water as possible. The outer wall of the release cylinder is equipped with a position indicator light to facilitate the person who falls into the water to see the rescue automatic inflatable lifebuoy. After reaching the release position, the electric telescopic rod can be started to push the automatic inflatable lifebuoy out of the release cylinder, so that the sealing cylinder cover can be squeezed open, and the automatic inflatable lifebuoy can be released around the person who falls into the water or even in the hands of the person who falls into the water for rescue work;

[0018] 3. If the person who falls into the water fails to obtain the lifebuoy due to unexpected factors such as water flow and strong wind, other spare automatic inflatable lifebuoys can be deployed, without returning to the shore to load the automatic inflatable lifebuoy again, which can effectively improve the success rate of rescue;

[0019] 4. When there is no suitable drone body for loading heavier equipment brackets, the loading cylinder can be removed from the equipment bracket and loaded on the drone landing gear through the No. 2 mounting frame, so that it can be used for temporary water rescue work;

[0020] 5. Such water lifebuoy delivery equipment can be equipped with multiple foldable and storable automatic inflatable lifebuoys for lifesaving work, so as to avoid the lifebuoys affecting the flight stability and speed of the drone. The whole equipment is easy to disassemble and install. It is not only suitable for the rapid saturation rescue of a single person who falls into the water, but also suitable for the water lifesaving work of multiple people who fall into the water. It has good applicability. The equipment is loaded and transported by the drone, hoisted and dropped by a steel wire rope, and pushed and delivered by an electric telescopic rod, so that the folded automatic inflatable lifebuoy can fall around the person who falls into the water as much as possible or even at hand, with good delivery accuracy.
