[0041] It should be noted that the bottom of the first groove 5 refers to the inner surface of the first groove 5 near the back of the backpack. By embedding the second groove 6 into the first groove 5, the water retrieval module 3 is placed on the outside of the ground station module 4, which reduces the size of the front of the backpack and prevents the ground station module 4 from slipping off when the backpack is opened vertically.

[0042] The cover plate 2 covers the front of the bladder body 1 and is detachably connected to the bladder body 1, and is used to cover the first groove 5 and the second groove 6;

[0043] Preferably, the cover plate 2 is made of rigid PVC plastic to improve the impact resistance of the front of the backpack.

[0044] Preferably, the edge of the cover plate 2 is connected to the bag body 1 by a buckle, making the connection between the backpack and the cover plate 2 more secure.

[0045] The water rescue module 3 is used to travel between the water area and the shore, and to carry the person who fell into the water.

[0046] The ground station module 4 is used to remotely control the movement direction and speed of the water-falling salvage module 3.

[0047] Preferably, the ground station module 4 is a remote control handle.

[0048] It should be noted that when a rescue mission is required, the backpack is placed on the ground, cover 2 is opened, and the water retrieval module 3 is taken out from the upper first groove 5 and placed in the water; then, the ground station module 4 is taken out from the second groove 6 at the bottom of the first groove 5; finally, using the ground station, the water retrieval module 3 is controlled to quickly move to the water area and carry the person back to shore. After the rescue mission is completed, the ground station module 4 and the water retrieval module 3 are placed back into the second groove 6 and the first groove 5 in reverse order.

[0049] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that, as Figure 3 As shown, the water-falling salvage module 3 includes a mobile platform 8, a communication unit, a control unit, and an inflatable float 7;

[0052] It should be noted that when the water-drowning salvage module 3 is housed in the second groove 6, the air-inflatable float 7 is in a compressed state, thereby saving storage space.

[0053] The mobile platform 8 includes two rotatably connected mobile floats 81; the two mobile floats 81 are mirror-symmetrical along the rotation axis; a water jet propulsion device 82 is fixed to the tail of each mobile float 81; the water jet propulsion device 82 is electrically connected to the control unit and is used to provide power to the water-falling salvage module 3.

[0054] Preferably, the aforementioned movable float 81 is made of PVC plastic.

[0055] It should be noted that PVC plastic sheets are lightweight and durable, with good compressive strength and waterproof performance, and are not easily deformed, thus improving the strength and buoyancy of the mobile floating board 81.

[0056] Preferably, the two mobile floats 81 of the mobile platform 8 are flattened out with a streamlined front end, thereby reducing the resistance of the mobile platform 8 when moving on the water surface and reducing the rescue waiting time.

[0057] Preferably, the upper surface of the movable float 81 is provided with a sealing cavity 83; the sealing cavity 83 is filled with a plurality of heating pads;

[0058] It should be noted that after the person who fell into the water opens the sealed cavity 83, they can take out the heating patch and apply it to their skin. This allows the person to receive active local heating while immersed in water, effectively relieving hypothermia and prolonging the time the person can float on the water.

[0059] Preferably, after the airbag is inflated, it is positioned between the water jet propulsion device 82 of the two flattened movable floats 81 to avoid blocking the water jet flow from the water jet propulsion device 82 and affecting the moving speed and direction of the movable platform 8.

[0060] It should be noted that with technological advancements, waterjet propulsion systems have been widely applied in various types of vessels. Some waterjet propulsion systems are designed with fully digital interfaces, offering high precision in control angles and high integration, making them compatible with remote control systems and facilitating system integration and secondary development.

This propulsion method enables rapid turning and reversing operations. Compared to traditional propeller propulsion, waterjet propulsion systems do not have exposed propellers, thus offering greater safety and avoiding the risk of injury to personnel falling into the water.

[0061] The communication unit is fixed inside any of the mobile floating plates 81 and is data connected to the ground station module 4 and the control unit. It is used to receive control signals from the ground station module 4 and send them to the control unit.

[0062] Preferably, the communication unit is a radio transceiver that communicates with the ground station module 4 via radio.

[0063] It should be noted that the above control signals include the direction of movement and the speed of movement; the control module controls the water spray speed of the two water jet propulsion devices 82 according to the received control signals, so as to realize the motion control of the water-falling salvage module 3.

[0064] The control unit is fixed inside any of the movable floats 81 and is used to control the water jet propulsion device 82.

[0065] It should be noted that the above-mentioned control unit can be implemented by a programmable logic controller (PLC), and this embodiment of the present invention does not limit it.

[0066] The inflatable float 7 is fixed to the tail of the mobile platform 8 and is used to provide a resting platform for people who fall into the water; the inflatable float 7 includes an air bladder and a self-inflating device.

[0067] Preferably, the self-inflating device is an inflatable steel cylinder connected to the air bladder via a one-way blowing pipe; the air bladder is deflated via an outlet pipe.

[0068] It should be noted that the aforementioned gas cylinder automatically fills the air bag with high-pressure carbon dioxide gas when it comes into contact with water.

[0069] Example 3

[0070] The difference between this embodiment and Embodiment 1 is that the outer surfaces of both the bag body 1 and the cover plate 2 are coated with a waterproof coating to improve the backpack's water-resistant capability.

[0071] The cover plate 2 is connected to the front of the bag body 1 via a circumferentially arranged waterproof zipper, further improving the bag's sealing performance.

[0072] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
