Description

Technical Field

[0001] This utility model relates to the field of rescue protection equipment technology, and in particular to a protective device for maritime rescue equipment. Background Technology

[0002] Drones are widely used as efficient aerial transport tools, enabling remote, targeted delivery of supplies. In the field of drone-based water rescue, drones can be used with droppers to rescue people who have fallen into the water; this method of airdropping water rescue equipment is faster and more convenient.

[0003] In the field of drone-based water rescue, the main method is airdropping lifebuoys. A utility model patent, CN2022211253102, entitled "A Drone for Marine Rescue," utilizes an airdrop device to deploy lifebuoys. Because the lifebuoys are lightweight, counterweights are added to accelerate their descent. However, current methods directly drop the lifebuoy without protective devices, causing it to fall directly onto the water's surface, potentially damaging it.

[0004] Based on this, this application designs a protective device for protecting maritime rescue equipment, which houses the maritime rescue equipment inside the protective device for protection. After the equipment falls into the water, it can be quickly opened to release the maritime rescue equipment. Utility Model Content

[0022] See Figures 5-9The auxiliary hoisting mechanism 200 includes a lateral auxiliary hoisting mechanism, which includes a front lateral auxiliary hoisting rope 201, a rear lateral auxiliary hoisting rope 202, a storage pull rope 203, a front storage cover 204, a rear storage cover 205, a front through hole 206 and a rear through hole 207 at the left and right ends of the bottom front side of the lower shell 101, a front hollow guide rod 208 near each front through hole 206 and a rear hollow guide rod 209 near each rear through hole 207 fixed at the bottom of the lower shell 101, and an intermediate cover 210 connected to the front storage cover 204 and the rear storage cover 205. The left and right ends of the front transverse auxiliary lifting rope 201 are respectively threaded through the corresponding front hollow guide rod 208 and the front through hole 206 and placed inside the lower shell 101 to form a lifting rope. The front storage cover 204 is pasted and fixed to the bottom of the lower shell 101 to store the excess 2011 of the front transverse auxiliary lifting rope 201. The left and right ends of the rear transverse auxiliary lifting rope 202 are respectively threaded through the corresponding rear hollow guide rod 209 and the rear through hole 207 and placed inside the lower shell 101 to form a lifting rope. The rear storage cover 205 is fixed to the bottom of the lower shell 101 to store the excess 2021 of the rear transverse auxiliary lifting rope 202. The front and rear ends of the storage pull rope 203 are respectively fixed to the front fixed shaft 212 and the rear fixed shaft 213. The storage pull rope 203 is placed inside the lower shell 101. The front fixed shaft 212 of the storage pull rope 203 is sleeved and fixed on the remaining 2011 of the front transverse auxiliary lifting rope 201 located inside the lower shell 101, and the rear fixed shaft 213 is sleeved and fixed on the remaining 2021 of the rear transverse auxiliary lifting rope 202 located inside the lower shell 101. A bottom cover hole is opened at the bottom of the lower shell 101 corresponding to the position of the middle cover 210. A bottom cover 211 is installed inside the bottom cover hole, and the storage pull rope 203 is between the bottom cover 211 and the middle cover 210.

[0023] In this embodiment, the storage pull rope 203, the front storage cover 204, and the rear storage cover 205 are used to store the front and rear lateral auxiliary lifting ropes when not in use. The middle cover 210 is used to store the storage pull rope 203. When the lateral auxiliary lifting ropes are needed, the protective shell 100 is flipped up so that the lower shell 101 is on top and the upper cover 102 is on the bottom. The front and rear lateral auxiliary lifting ropes are pulled up to remove the excess rope inside the lower shell 101. The removed front and rear lateral auxiliary lifting ropes are used for lifting, thus completing the pre-lifting preparation work, such as attaching the removed front and rear lateral auxiliary lifting ropes to the lower hook of the drone's delivery device. The front lateral auxiliary lifting rope 201 and the rear lateral auxiliary lifting rope 202 can be made of steel wire rope. When there is no need to use the horizontal auxiliary lifting ropes for hoisting, the bottom cover 211 can be opened and the storage pull rope 203 can be manually pulled back into the front and rear storage covers. The storage pull rope 203 is stored between the middle cover 210 and the bottom cover 211.

[0024] The auxiliary lifting mechanism 200 also includes a longitudinal auxiliary lifting mechanism, which includes a longitudinal auxiliary lifting ring 214 fixed to at least one side of the lower housing 101. The longitudinal auxiliary lifting ring 214 can be used as a handle or for lifting, such as attaching the longitudinal auxiliary lifting ring 214 to the lower claw of the delivery device on the UAV.

[0025] The zipper mechanism 300 includes a left zipper assembly 301, a right zipper assembly 302, a pull cord 303, a zipper unlocking handle 304, and a pull cord protection strip 305. The left zipper assembly 301 is fixed to the outer left end of the upper cover 102 and the lower shell 101, and the right zipper assembly 302 is fixed to the outer right end of the upper cover 102 and the lower shell 101. The two ends of the pull cord 303 are fixedly connected to the left zipper assembly 301 and the right zipper assembly 302, respectively. The zipper unlocking handle 304 is fixed at the middle position of the pull rope 303. The lower outer edge of the upper cover 102 has an upper recess along the pull rope from left to right or from right to left. The upper outer edge of the lower shell 101 has a lower recess along the pull rope from left to right or from right to left. When the upper cover 102 and the lower shell 101 are closed, the upper and lower recesses form a groove 306 for accommodating the pull rope protection strip 305. The pull rope protection strip 305 is fitted onto the pull rope 303.

[0026] The left zipper assembly 301 includes an upper left zipper buckle 3011 fixed to the bottom left side of the upper cover 102, a lower left zipper buckle 3012 fixed to the top left side of the lower shell 101, and a left zipper 3013 that locks the upper left zipper buckle 3011 and the lower left zipper buckle 3012, which are located on the same straight line, when the upper cover 102 and the lower shell 101 are closed. The right zipper assembly 302 includes an upper right zipper buckle 3021 fixed to the bottom right side of the upper cover 102, a lower right zipper buckle 3022 fixed to the top right side of the lower shell 101, and a right zipper 3023 that locks the upper right zipper buckle 3021 and the lower right zipper buckle 3022, which are located on the same straight line, when the upper cover 102 and the lower shell 101 are closed. The two ends of the pull cord 303 are fixedly connected to the left zipper 3013 and the right zipper 3023, respectively.

[0027] In this embodiment, the pull rope protection strip 305 is a hollow strip with a semi-circular cylindrical shape, which can protect and directionally store the pull rope 303, avoiding interference with the operation.

[0028] Beforehand, maritime rescue equipment, especially stretcher-type maritime rescue equipment, is placed and stored in protective equipment. The rescue center dispatches drone operators to pull up the front lateral auxiliary lifting rope 201 and rear lateral auxiliary lifting rope 202, which are in a stored state on the protective equipment, to remove the excess material inside the lower shell 101. Then, the front lateral auxiliary lifting rope 201 and rear lateral auxiliary lifting rope 202 are attached together to the hook at the bottom of the drone's delivery device, thus completing the drone lifting preparation. The drone is then operated to reach the area where the person to be rescued is located. After locking onto the person's position, the delivery device remote controller is used to control the lower hook of the delivery device to separate and deploy the protective equipment. After the protective equipment falls into the water, the upper cover 102 has an arc-shaped structure and controls the weight of the protective equipment containing the maritime rescue device, causing the protective equipment to float on the sea surface. The rescuers pull the zipper unlocking handle 304, which drives the left zipper 3013 and right zipper 3023 connected to the pull rope 303, so that the zippers are unlocked and the upper cover 102 and lower shell 101 of the protective equipment are opened to quickly release the maritime rescue device inside the protective equipment.
