Description

Technical Field

[0001] The present invention relates to rescue equipment, in particular to fire-fighting water surface rescue equipment, belonging to the technical field of water surface rescue. Background Art

[0002] Traditional surface rescue methods mainly include throwing rescue, rowing rescue and direct rescue; throwing rescue mainly relies on throwing lifebuoys or life ropes for rescue. This method has the problems of limited throwing distance and low throwing accuracy, and the person who falls into the water needs to remain conscious; rowing rescue mainly uses rowing to approach the person who falls into the water for rescue. This method is too dependent on the boat, and there is a risk of rescuers being pulled into the water; direct rescue mainly involves rescuers going into the water, swimming close to the person who falls into the water, and dragging the person who falls into the water to a safe area. However, this method has high requirements on the physical strength of the rescuers and the cooperation of the person who falls into the water, and the rescue risk is relatively high.

[0003] The Chinese patent, entitled "A Water Surface Gliding Rapid Rescue Robot" (patent number ZL202222240654.4), discloses a water surface gliding rapid rescue robot technology. However, while the robot can avoid the problem of a drowning person losing their grip due to exhaustion, the rescue method it uses is the same as traditional remote-controlled rescue equipment, requiring the drowning person to remain conscious. However, when a drowning person is in distress, their spirits are usually highly tense and their thinking is confused, making it difficult for them to effectively cooperate with the robot to complete the rescue mission, thus affecting the rescue efficiency. The robot is also unable to respond to rescue missions where the drowning person has been drowning for a long time and is unconscious. The Chinese patent title is "A rescue underwater robot and rescue method based on multimodal drowning recognition" (patent number ZL202411658719.4), which discloses a rescue underwater robot technology based on multimodal drowning recognition. Although the robot can use the pop-up rescue device to form a ring structure on the waist of the drowning person, and fix it by adsorption, and then use the airbag inflation method to enable the drowning person to float to the surface smoothly; but in order to ensure that the rescue device can be successfully fixed on the waist of the drowning person, the entire robot must be sufficiently close to the drowning person, and there is no reset structure between the rescue device and the robot. Once the rescue device is accidentally touched after popping out, the overall rescue mission will be reset, and the fault tolerance rate is too low. For this reason, a fire-fighting surface rescue equipment is proposed. Summary of the Invention

At the same time, the first waterproof probe 401 and the second waterproof probe 403 are used to respectively collect surface images and underwater images in real time, and the collected images are fed back to the remote control terminal through the surface central controller 402 and the underwater central controller 404, so that the remote control terminal can perform remote control operations according to the fed-back images.

[0041] When the drowning person is conscious and can cooperate with the rescue mission, it is only necessary to use the underwater driving mechanism 5 to drive the submersible traction assembly 2 to drive the U-shaped float 101 to move to the drowning person. The drowning person actively grabs the U-shaped float 101 so that the U-shaped float 101 can provide sufficient buoyancy for the drowning person. Then, the underwater driving mechanism 5 drives the submersible traction assembly 2 to drive the surface floating assembly 1 to transfer the drowning person to a safe area, thereby completing the rescue operation of the traditional remote-controlled rescue equipment. The specific effect is as follows: Figure 14 shown.

[0042] When the drowning person is in a state of extreme nervousness, confused thinking and struggling in the water, he sends a casting command to the surface central controller 402 through the remote control terminal, and then the surface central controller 402 starts the electric push rod 302 according to the command. The working electric push rod 302 drives the connecting block 303 to move, and the moving connecting block 303 drives the arc-shaped splint 304 to open, and then the compressed spring 803 pushes the inner slide 802 to move in the sleeve 801, and the moving inner slide 802 uses the arc-shaped push plate 804 to drive the diving casing 201 to quickly separate from the U-shaped float 101. When the submersible casing 201 needs to dive, the micro-boosting pump 603 is started by the underwater central controller 404 through the remote control terminal. The working micro-boosting pump 603 extracts the air in the filling air bag 602 and injects it into the pressure-resistant gas cylinder 601 for compression through the one-way valve. Then, the gradually shrinking and deforming filling air bag 602 is used to form a negative pressure in the submersible control chamber 202, so that under the action of the negative pressure, water is sucked into the submersible control chamber 202 through the suction and discharge port 605, causing the submersible casing 201 to dive as a whole. The filter screen 606 is used to intercept debris carried in the water. When it is necessary to control the direction of movement of the diving housing 201 in the water, the micro reduction motor 703 is started by using the underwater central controller 404 through the remote control terminal. The working micro reduction motor 703 drives the worm 704 to rotate. The rotating worm 704 drives the worm wheel 705 to rotate using the teeth. The rotating worm wheel 705 drives the connecting slider 708 to move using the adjusting disk 706. The moving connecting slider 708 drives the steering rudder plate 707 to adjust the angle, so that the steering rudder plate 707 after the angle adjustment can be used to control the diving direction of the diving housing 201.

[0043] When the two submersible shells 201 dive in the water respectively, the moving submersible shell 201 drives the lashing rope 903 to be pulled out from the gathering frame 103 by using the fixed block 904. After the lashing rope 903 is completely pulled out, the moving submersible shell 201 drives the lashing rope 903 to pull the gathering frame 103 and the U-shaped float 101. Then, the remote control terminal uses the underwater image collected by the second waterproof probe 403 to control the two submersible shells 201 to pass through the two sides of the body of the drowning person respectively and continue to dive, so as to use the lashing ropes 903 on both sides of the body of the drowning person to guide the gathering frame 103 and the U-shaped float 101. Ensure that the U-shaped float 101 can smoothly rest against the body of the drowning person. It is best to place it under the armpit of the drowning person to provide sufficient buoyancy for the drowning person. When the drowning person calms down and can cooperate with the rescue mission, the solenoid valve 604 can be controlled to inject the compressed air in the pressure-resistant gas cylinder 601 into the filling airbag 602, causing the filling airbag 602 to expand rapidly, squeezing out the water in the diving control chamber 202, and causing the diving housing 201 to float as a whole. Then, the underwater driving mechanism 5 drives the diving housing 201 to drive the tying rope 903 to continue to drag the U-shaped float 101 as a whole forward, so as to transfer the drowning person to a safe area. The specific effect is as follows: Figure 13 shown.

[0044] When the drowning person becomes unconscious due to prolonged drowning, the remote control terminal controls the underwater driving mechanism 5, the diving control mechanism 6 and the direction adjustment mechanism 7 to drive the diving traction assembly 2 to dive as a whole. During the underwater diving process, the diving traction assembly 2 cooperates with the binding mechanism 9 to forcibly drag the surface floating assembly 1 into the water as a whole. Then, the acquisition unit 4 is cooperated to quickly lock the position of the drowning person in the water, and the two diving traction assemblies 2 are controlled to pass through the drowning person's armpits according to the image feedback from the acquisition unit 4. When the surface floating assembly 1 as a whole contacts the drowning person's body as the diving traction assembly 2 drags, the two diving traction assemblies 2 are driven by remote control to drive the binding rope 903 to quickly complete the crossover, so that the drowning person's body is tied to the U-shaped float 101 in a cross manner, and then the U-shaped float 101 can be used to drive the drowning person's body to float to the surface; then the remote control diving traction assembly 2 is used to move in the opposite direction as a whole, so as to push the U-shaped float 101 and the drowning person while maintaining the cross-binding effect, so as to transfer the drowning person to a safe area for further rescue operations. The specific effect is as follows: Figure 12 shown.

[0045] The winding wheel 901 is used to rotate the central shaft 902 to drive the winding wheel 901 to rotate after the surface rescue equipment is used. The rotating winding wheel 901 drives the binding rope 903 to be reeled in, so that the excess binding rope 903 can be retracted into the interior of the binding frame 103. The constraint block 991 is used to limit the bound binding rope 903 on the U-shaped float 101, and when the binding rope 903 is dragged by the diving traction component 2, the binding rope 903 can slide out smoothly from the constraint block 991.

Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
