[0020] The quick lock assembly 14 comprises a locking frame 141, an insertion block 144 and a clamping block 145; the locking frame 141 is fixedly connected with one end of the second waist fixing band 12, a sliding groove 142 is formed in the side surface of the locking frame 141, and a clamping hole 143 is formed in the sliding groove 142; the insertion block 144 is fixedly connected with one end of the first waist fixing band 11, and can slide along the sliding groove 142; the clamping block 145 is matched with and clamped in the clamping hole 143, a first slot 146 is formed in the insertion block 144 for sliding of the clamping block 145, a telescopic spring 147 is arranged between the clamping block 145 and the bottom wall of the first slot 146, and the telescopic spring 147 provides elastic support for the clamping block 145, so that the clamping block 145 is stably clamped in the clamping hole 143; a limiting block 148 is arranged on the side surface of the clamping block 145, a limiting groove 149 is formed in the side wall of the first slot 146 for sliding of the limiting block 148, the limiting block 148 cooperates with the limiting groove 149 to limit the sliding direction of the clamping block 145, preventing the clamping block 145 from falling off from the first slot 146, and ensuring the connection stability of the quick lock assembly 14; when unlocking, the clamping block 145 is pressed to compress the telescopic spring 147, so that the clamping block 145 is separated from the clamping hole 143, and the insertion block 144 can be pulled out of the sliding groove 142, realizing quick unlocking.

[0021] The buoyancy adjustment system 2 includes a buoyancy bladder assembly 21, an inflation assembly 22, a deflation valve 23, and a pressure sensor 26. The buoyancy bladder assembly 21 is located on the back of the mounting plate 15. A storage box 24 is fixed to the mounting plate 15 by bolts. The storage box 24 is waterproof. The inflation assembly 22 and the deflation valve 23 are both located inside the storage box 24. The inflation assembly 22, the deflation valve 23, and the buoyancy bladder assembly 21 are sealed together by an inflation pipe 25 to control the inflation and deflation of the buoyancy bladder assembly 21. The pressure sensor 26 is embedded in the side of the first leg fixing strap 17 and the second leg fixing strap 19. The pressure sensor 26 is a thin-film pressure sensor and is electrically connected to the control module. It is used to detect the pressure signal between the user's legs and the fixing straps and transmit the electrical signal to the control module. The magnitude of the pressure signal can reflect the impact force of the water flow and the buoyancy adaptation of the user, providing data for buoyancy adjustment.

[0022] The buoyancy bladder assembly 21 includes a main buoyancy bladder 211 and a secondary buoyancy bladder 212. The two main buoyancy bladders 211 are respectively set on the first waist fixing belt 11 and the third waist fixing belt 13, and the secondary buoyancy bladder 212 is set on the back of the storage box 24. Both the main buoyancy bladder 211 and the secondary buoyancy bladder 212 are made of high-strength waterproof and wear-resistant rubber material, and both are equipped with independent inflation and deflation interfaces. The independent inflation and deflation interfaces can realize the individual inflation and deflation adjustment of the main and secondary buoyancy bladders, and buoyancy distribution can be flexibly adjusted according to rescue needs. For example, when rescuers carry people in distress, they can inflate the secondary buoyancy bladder 212 separately to increase the buoyancy of the back and maintain body balance.

[0023] The inflation assembly 22 includes an inflation pump 221 and an air tank 222. Both the inflation pump 221 and the air tank 222 are housed in a storage box 24. The inflation pump 221 is a miniature DC inflation pump, and the air tank 222 is a high-pressure miniature air tank that pre-stores high-pressure nitrogen. The inflation pump 221 and the air tank 222 are sealed to the main buoyancy bladder 211 and the auxiliary buoyancy bladder 212 through an inflation pipeline 25. A pressure regulating valve 223 is installed on the inflation pipeline. The pressure regulating valve 223 is an electromagnetic pressure regulating valve that is electrically connected to the control module. The air tank 222 can quickly inflate the buoyancy bladder, which is suitable for rapid buoyancy enhancement in emergency situations. The inflation pump 221 is used to replenish the air tank 222 and to finely inflate the buoyancy bladder. The pressure regulating valve 223 can detect and control the air pressure in the inflation pipeline 25 in real time to prevent the buoyancy bladder from being damaged due to over-inflation.

[0024] The control module includes a main control chip and a 5G+LoRa communication module. The main control chip uses an STM32 series microcontroller and is located inside the storage box 24. It is electrically connected to the pressure sensor 26, the deflation valve 23, the inflation pump 221, and the pressure regulating valve 223. It receives the pressure signal transmitted by the pressure sensor 26 and controls the operation of the deflation valve 23, the inflation pump 221, and the pressure regulating valve 223 according to the preset program logic to achieve intelligent automatic adjustment of buoyancy. The 5G+LoRa communication module is electrically connected to the main control chip and is located on the outside of the storage box 24. It combines the high-speed data transmission advantages of 5G communication with the long-distance, low-power, and anti-interference advantages of LoRa communication. It can realize real-time data transmission between rescue personnel and the command center, such as location information, buoyancy data, pressure signals, and long-distance communication. It is suitable for complex water rescue environments with no mobile network or weak network signal.

[0025] The multi-functional auxiliary rescue component 4 includes a rescue item storage box 41 and a distress signal module 42. The rescue item storage box 41 is a waterproof plastic box, which is fastened to one side of the first connecting strap 16 and the second connecting strap 18 via a snap fastener. It has multiple compartments inside for storing small rescue tools such as rescue knives, traction ropes, hooks, and first-aid supplies such as bandages and disinfectant wipes. The box uses a flip-top snap fastener structure for easy and quick access. The distress signal module 42 integrates an LED warning light, a multi-mode buzzer, a Beidou short message module, and a GPS positioning system. The distress signal module 42 is located on the top of the storage box 24 and is electrically connected to the main control chip. The LED warning light is high-brightness. The flashing warning light emits alternating red and blue visual distress signals, making it easier for nearby rescuers to spot the person in low-visibility environments such as nighttime or foggy weather. The multi-mode buzzer emits high-decibel audible distress signals in both continuous and intermittent modes to suit different rescue scenarios. The BeiDou short message module enables the sending and receiving of text messages in water environments without mobile networks. Rescuers can send distress text messages via preset commands or external buttons, and the command center can also send command instructions via BeiDou short messages. The GPS positioning system can obtain the precise location information of rescuers in real time and transmit it to the command center through the main control chip and 5G+LoRa communication module, enabling real-time location tracking of rescuers.

[0026] Work process: The user wraps the first waist fixing strap 11, the second waist fixing strap 12, and the third waist fixing strap 13 around the waist, inserts the insert block 144 into the sliding groove 142 of the locking bracket 141, and the locking block 145 engages with the locking hole 143 under the action of the telescopic spring 147, realizing the quick fastening of the waist fixing strap; then the first leg fixing strap 17 and the second leg fixing strap 19 are respectively put on the left and right legs, and the tightness is adjusted by the elastic Velcro, completing the wearing and fixing of the device. The multi-point fixation of the waist and legs ensures the stability of the device.

[0027] After the device is worn, the pressure sensor 26 detects the pressure signal between the user's legs and the fixing strap in real time and transmits the signal to the main control chip. When the water flow is rapid and the user experiences increased water pressure, causing the leg pressure signal to exceed the preset threshold of the main control chip, the main control chip controls the valve of the air tank 222 to open. High-pressure gas is then rapidly inflated into the buoyancy bladder assembly 21 through the inflation pipe 25. At the same time, the pressure regulating valve 223 monitors the air pressure in real time to prevent over-inflation. When excessive buoyancy obstructs the user's movement and the leg pressure signal falls below the preset threshold, the main control chip controls the deflation valve 23 to open, deflating the buoyancy bladder assembly 21. If the air pressure in the air tank 222 is insufficient, the main control chip controls the inflation pump 221 to start, replenishing the air tank 222 or directly performing fine inflation of the buoyancy bladder. Users can also control the individual inflation and deflation of the main buoyancy bladder 211 and the secondary buoyancy bladder 212 via external buttons to adjust the buoyancy distribution according to their actual needs.

[0028] During operation, the GPS positioning system acquires the user's location information in real time. The main control chip transmits data such as location information, pressure signal from pressure sensor 26, and air pressure signal from buoyancy bladder to the command center via the 5G+LoRa communication module. The command center can monitor the location of rescue personnel and the on-site environment in real time and send command instructions to rescue personnel via the 5G+LoRa communication module. In water environments without mobile networks, the 5G+LoRa communication module automatically switches to LoRa mode to achieve long-distance, low-power communication.

[0029] When rescuers encounter danger, they can activate the distress signal module 42 via an external button. The LED warning light will then flash, and the multi-mode buzzer will activate a high-decibel distress signal mode. Simultaneously, the GPS positioning system will send precise location information to the command center via the 5G+LoRa communication module. In extreme environments without any network, the Beidou short message module can send a distress text message containing location information, enabling distress calls even in network-free environments. During the rescue, rescuers can quickly open the rescue supplies storage box 41 to retrieve auxiliary rescue items, improving the efficiency of the rescue operation.

[0030] When rescuers need to quickly disengage from the device, they can press the locking block 145 to compress the telescopic spring 147, causing the locking block 145 to disengage from the locking hole 143, and then pull the insert block 144 out of the sliding groove 142. This allows them to quickly untie the waist restraint belt and then the leg restraint belt, thus enabling the device to be quickly disassembled.
