Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a flight rescue boat with a load system. Background Technology

[0002] In the field of drone technology, different types of drones are needed for different application scenarios, among which special drones are needed for water rescue.

[0003] Some manufacturers have developed an amphibious rescue stretcher and control module, including a shell, rotor, and propeller. Driven by the rotor, the air rescue boat moves quickly from the air to the person to be rescued. The drowning person then holds onto the handles on the shell to keep floating. Finally, the propeller moves the air rescue boat and the drowning person to the shore.

[0004] However, in situations involving multiple drownings, the limited number of handle positions makes it difficult to provide grip for multiple people. In contrast, the power of a rescue boat is sufficient to tow multiple people on the water. Therefore, there is a challenge in how to use it for multiple-person rescues. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0019] Figure 1-6 As shown, this utility model provides a flight rescue boat load system, including a flight rescue boat, with the load system installed on the hull 1 of the flight rescue boat, and realizing multi-person rescue through the preset load system.

[0020] The specific load system includes a gripping unit and a safety lock unit. A recessed mounting cavity 11 is pre-set on the upper side of the tail of the housing 1. The gripping unit specifically includes a gripping rod 21 and a connecting rod 22 that are pre-set in the mounting cavity 11. Both ends of the gripping rod 21 are vertically fixed with the connecting rod 22. The other end of the connecting rod 22 is mounted on the inner wall of the mounting cavity 11 by conventional hardware hinge. When the linkage 22 rotates to the vertical position, the gripping rod 21 is horizontal and higher than the upper side of the housing 1, providing a place for the drowning person to hold on; When the linkage 22 rotates to the horizontal position, the gripping rod 21 is horizontal and hidden inside the mounting cavity 11, so as to avoid the protruding part affecting the storage and transportation of the flight rescue boat.

[0021] In actual rescue operations, multiple drowning victims are often encountered. Therefore, the aforementioned gripping rod 21 adopts a hollow structure and is equipped with a pair of extension rods 23. The extension rods 23 can slide and extend within the gripping rod 21, providing gripping support for more drowning victims and achieving the goal of rescuing multiple people, thus greatly improving rescue efficiency.

[0022] The gripping rod 21 has a pre-set opening 211, and the extension rod 23 has a pre-set elastic locking bead 231. A support spring 212 is also pre-set between the extension rods 23. When the gripping rod 21 moves to disengage from the mounting cavity 11, the support spring 212 pushes the extension rods 23 to move in opposite directions until the elastic locking bead 231 aligns with and is inserted into the opening 211, thereby automatically releasing the extension rod 23 and further facilitating rescue missions for multiple people.

[0023] Furthermore, a rubber sleeve is fitted on the gripping rod 21, and anti-slip texture is pre-set on the extension rod 23. In actual rescue, the rubber sleeve and anti-slip texture ensure that the drowning person can hold the grip stably.

[0024] In addition, to further ensure the rescue, the gripping unit needs to be able to deploy as automatically as possible, but it is also necessary to avoid increasing the load on the air rescue boat too much. Therefore, a safety lock unit with a purely mechanical linkage structure is set up.

[0025] The specific safety lock unit includes a locking rod 34 and a power assembly. A locking groove 13 is pre-set on the inner wall of the mounting cavity 11 near the gripping rod 21, and the locking rod 34 is slidably inserted into the locking groove 13. When the locking rod 34 extends, it blocks the upper side of the gripping rod 21, thereby locking the movement of the gripping rod 21. Furthermore, a torsion spring is pre-set at the hinge of the linkage rod 22. When the locking rod 34 retracts into the locking groove 13, the elastic force of the torsion spring causes the gripping unit to rotate, thereby achieving the purpose of automatically unfolding the gripping unit.

[0026] The aforementioned power assembly is specifically installed inside the rear of the housing 1. An installation channel 12 is pre-set in the rear of the housing 1. One end of the installation channel 12 is connected to the locking groove 13. The power assembly includes a power rod 31 rotatably set in the installation channel 12. A connecting rope 32 is pre-set between one end of the power rod 31 and the locking rod 34. A thrust spring 342 for pushing the locking rod outward is pre-set in the locking groove 13. When the power rod 31 rotates up and down, the connecting rope 32 and the thrust spring 342 drive the locking rod 34 to push and pull, realizing the extension and retraction of the locking rod 34 in the locking groove 13.

[0027] A hollow counterweight 33 is fixed to the other end of the power rod 31, and the mounting channel 12 extends downward toward the housing 1 near the counterweight 33 to penetrate the housing 1. When the air rescue boat is transported and stored, the end of the power rod 31 with the counterweight 33 is lower, while the other end supports the locking rod 34 to remain extended out of the locking groove 13. When the air rescue boat falls into the water, the hollow counterweight 33 is affected by buoyancy, causing the power rod 31 to rotate, thereby pulling the locking rod 34 back, unlocking the grip unit, and achieving the purpose of automatically releasing the grip unit. Furthermore, the safety lock unit uses a small and simple accessory structure, avoiding excessive load.

[0028] The working principle of this utility model is as follows: During storage, transportation, and flight of the air rescue boat, the counterweight 33 is subjected to gravity. At this time, the power rod 31 supports the locking rod 34 through the connecting rod 32 to extend out of the locking groove 13. The locking rod 34 then abuts against the upper side of the grip rod 21, thereby restricting the movement of the grip rod 21. When the air rescue boat falls into the water, the hollow counterweight 33 is affected by buoyancy, causing the power rod 31 to rotate, thereby pulling the locking rod 34 back and unlocking the grip unit. At this time, the linkage rod 22 rotates to the vertical position, and the grip rod 21 is horizontal and higher than the upper side of the shell 1, providing a place for the drowning person to hold on.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
