The working principle is as follows: when a person falls from the bridge due to foot loss, the body weight of the person completely leans against the side face of the telescopic rod A202 and has a falling tendency, at the moment, the telescopic rod A202 and the special-shaped block 201 rotate outwards for a certain distance, at the moment, the side face of the special-shaped block 201 pushes the round rod A204 to move outwards, the other end of the round rod A204 is in contact with the upper end of the telescopic rod B205 and pushes outwards, and the piston rod end of the telescopic rod B205 pulls the emergency net bag 206 to turn from a vertical position to a horizontal position to catch the person falling off the bridge;
when a person is to be light and stands on the telescopic rod A202 to jump downwards, the telescopic rod A202 is forced to move downwards to drive the rack A208 to move downwards, the rack A208 drives the fixing plate A203 to rotate, the fixing plate A203 drives the round rod C211 to rotate through the pawl, the thin steel wire at one end of the round rod C211 is rapidly wound on the round rod C211, at the moment, the alarm mechanism on the bridge body part 1 sounds to remind the person standing on the upper end face of the telescopic rod A202 to return to the bridge and not stand in a dangerous place, if the person standing on the telescopic rod A202 does not respond, the person does not stand on the telescopic rod A202 due to curiosity or other reasons but wants to be light, at the moment, the thin steel wire is wound on the round rod C211, two control rods on the round rod B210 alternately contact two control rods on eight gears on the teeth of the round rod C211, the round rod C211 rotates continuously, the wound thin steel wire is gradually put outwards, and the control block 212 falls along with the thin steel wire discharged from the round rod C211, when the emergency net bag falls to a certain distance, the lower end of the control block 212 is in contact with a button on the upper end surface of the bridge body part 1, a switch of the motor A207 is turned on, the motor A207 works, the emergency net bag 206 is turned to be in a horizontal position from a vertical position, and a person jumping off the bridge is caught;
when a person falls from the river, passes through the bridge and is conscious, if the person falls into the river, the motor C311 is started to drive the synchronous belt 312 to rotate, because the ejection sequence of the three ejection mechanisms is different, the synchronous belt 312 drives the eccentric wheel 307 in the ejection mechanism which firstly accumulates force to rotate, the eccentric wheel 307 rotates to drive the slide block A308 to move forwards, the small cylinder on the side surface of the slide block A308 is in contact with the inclined surface at one end of the round rod D310 to push the round rod D310 to move towards the slide block B309, so that the slide block A308 moves to the other end of the slide block B309, when the slide block A308 moves backwards along with the rotation of the eccentric wheel 307, the small cylinder on the side surface of the slide block A308 clamps the round rod D310 to drive the round rod D310 to move backwards together, the round rod D310 drives the slide block B309 to move backwards, the slide block B309 gradually compresses the top spring at one end of the slide block B309 to enable the top spring to have strong elastic force, when the slide block B309 moves to the round rod D310 to be in contact with the inclined surface block on the upper end surface of the fixed block 306, the small cylinder on the side face of the sliding block A308 moves continuously through the groove at the lower end of the inclined plane block of the fixed block 306, and the sliding block B309 rebounds together with the round rod D310 because the inclined plane block on the upper end face of the fixed block 306 obstructs the inclined plane at one end of the round rod D310 and the elasticity of the top spring at one end of the sliding block B309, so that the pushing plate on the other end face of the sliding block B309 rebounds out of the corresponding life buoy A313; after the life buoy A313 is ejected out of the bridge body part 1, the life buoy A313 falls into the water in a circle along with the steel wires on the coil rack 302, a person falling into the water catches the life buoy A313, the electric cylinder 304 works to push the motor B305 to the side of the coil rack 302, the gear on the motor B305 is meshed with the large gear 303 on the coil rack 302, the motor B305 is started to drive the large gear 303 to rotate, the coil rack 302 is further driven to rotate, the steel wires are wound again, and the life buoy A313 connected with the steel wires on the coil rack 302 is pulled to the shore together with the person falling into the water on the life buoy A313 to save the person falling into the water; if two or three people falling into water need to be rescued, the motor C311 rotates to sequentially accumulate power for the two or three ejectors, so that the two or three life buoys A313 are thrown into the river, the electric cylinder 304 pushes the motor B305 to the side faces of the three coil racks 302 one by one, and the motor B305 works to save the people falling into water one by one.
When a person is out of the river and falls into the water and loses consciousness, or the person jumps down from the river by light and passes through the bridge, the motor E405 is started to drive the rotating rod B404 to move in the groove in the U-shaped plate 401, the life-saving net bag 406 nets the person falling into the water, the motor D403 is started, the rotating rod A402 rotates to wind the upper end of the life-saving net bag 406 while the motor E405 drives the rotating rod B404 to move upwards, and therefore the motor D403 and the motor E405 jointly act to rescue the person falling into the water.
