The following is a detailed description of the steps of using an emergency rescue device for river bank real-time monitoring in the present document with reference to fig. 1 to 5:
in the initial state: the compression spring 15 and the connecting spring 33 are in a compressed state; the extension spring 13 is in a stretched state;
when the work is started:
1. when the observation device 19 observes that a person falls into water and needs to be rescued, the electromagnet 25 is controlled to be powered on to generate magnetic force, so that the electromagnet 25 adsorbs the fixed magnet 26 to move towards one side close to the electromagnet 25, the fixed magnet 26 moves towards one side close to the electromagnet 25 to drive the fixture block magnet 27 to move towards one side close to the electromagnet 25 and compress the return spring 28, the fixture block magnet 27 moves towards one side close to the electromagnet 25 to enable the connecting magnet 29 to be separated from the fixture block magnet 27 in a magnetic force mode, the fixture block magnet 27 is enabled to leave the clamping groove 30, and therefore the closing plate 12 is not limited by the fixture block magnet 27 any more.
2. So that the closing plate 12 moves into the connecting cavity 14 under the resilience of the extension spring 13, and after the closing plate 12 moves into the connecting cavity 14, the supporting block 11 is no longer blocked by the closing plate 12, so that the supporting block 11 leaves the ejection cavity 16 under the resilience of the compression spring 15, and the supporting block 11 is ejected into the water by the resilience of the compression spring 15.
3. When the supporting block 11 is launched into the water by the resilience of the compression spring 15, the moving block 31 is no longer pressurized by the launching chamber 16, so that the moving block 31 moves away from the compressed gas tank 37 under the driving of the resilience force of the moving cavity 32, the moving block 31 moves away from the compressed gas tank 37 to drive the sliding rod 34 to move away from the compressed gas tank 37, the sliding rod 34 moves away from the compressed gas tank 37 to drive the sliding plate 36 to move away from the compressed gas tank 37, the sliding plate 36 moves away from the compressed gas tank 37 to drive the isolating plate 40 to move away from the compressed gas tank 37, and the isolating plate 40 moves away from the compressed gas tank 37 to move away from the gas guide pipe 38, thereby allowing compressed gas in the compressed gas tank 37 to enter the gas sparger 41 through the controller 39.
4. Then the jet 41 is started to provide forward power for the supporting block 11 on the water surface, then the supporting block 11 moves forward towards the position of the person falling into the water at a high speed until the position reaches the side of the person falling into the water, so that the person falling into the water can climb onto the upper end surface of the supporting block 11 through the pull ring 23, and then the jet 41 drives the supporting block 11 to return to the shore, so that the rescue for the person falling into the water is completed.
5. After the rescue for the man falling into the water is completed, the firefighter replaces the new compressed air tank 37 and pushes the supporting block 11 into the ejection cavity 16 again, when the supporting block 11 moves towards one side close to the thrust plate 17, the compression spring 15 is compressed and the moving cavity 32 moves towards one side close to the compressed air tank 37, the moving cavity 32 moves towards one side close to the compressed air tank 37 so as to drive the isolation plate 40 to move towards the air guide pipeline 38, and therefore the communication between the compressed air tank 37 and the air ejector 41 is sealed, and therefore gas in the compressed air tank 37 leaks.
6. When the supporting block 11 is completely moved into the ejection cavity 16, the electromagnet 25 is turned off to cut off the power, and then the closing plate 12 is manually pulled to close the outward opening of the ejection cavity 16, the fixture block magnet 27 is driven by the resilience force of the return spring 28 to move towards the clamping groove 30, so that the connecting magnet 29 is magnetically connected with the fixture block magnet 27, and the closing plate 12 is prevented from moving towards the connecting cavity 14.
