[0025] The embodiment of the utility model provides an electric inflatable rope throwing device for emergency rescue at a port or wharf.

[0026] See also Figure 1-Figure 7, including an electric air pump 1, a shoulder-fired launcher 4, a pneumatic reversing valve group 5, a towing warhead 8 and a sight 10. The pneumatic reversing valve group 5 is arranged inside the shoulder-fired launcher 4 through a guide single rod 11. An external control grip 12 is arranged at the bottom of the shoulder-fired launcher 4. The sight 10 is arranged on one side of the controller 7 through a control support rod 13 and an external clamp 14, which can effectively make the components more closely combined. The sight 10 has telescope, laser and infrared night vision functions. The towing warhead 8 is light in weight and can float on The rescue rope 9 is stored in the launching projectile by winding and can be quickly released when launching. The front end of the traction projectile has a fixed end of the rescue rope 9, and the strength can ensure that the rescue rope 9 does not fall off during the delivery process. The shoulder-fired launcher 4 is composed of 4 launching tubes, three of which are on the same plane and are arranged in upper, middle and lower positions, and the other is arranged parallel to the middle one. The middle connecting tube connects the launching tube and the terminal frame, and an electromagnetic starting valve group, an air pipeline, a power supply and a control circuit are installed inside. The operating handle is installed in the front of the lower part of the middle cylinder, and there is a trigger switch in front of the operating handle. The inside of the trigger switch is connected to the power supply and control system by a line. The rear of the middle cylinder is the end frame, and the end frame is installed with an electric air pump 1, an accumulator 2, a battery pack 3 and a protective cover. The accumulator 2 is composed of a detachable gas cylinder, and a nitrogen bladder is installed inside the gas cylinder. The nitrogen bladder can be compressed during inflation, and the nitrogen bladder is freely expanded during release. The shoulder-fired launcher 4 can continuously perform four bursts and repeated loading. There is a rescue rope 9 connecting fixing ring above the cylinder launch tube to ensure that the end of the rope is firmly connected after the rescue rope 9 is ejected. The electric air pump 1 is assembled by a DC 12v motor and an air pump. The power supply line is connected to the trigger switch, the controller 7, the pressure sensor 6 and the working indicator light. The controller 7 is composed of a control system, a display, an operation panel and a button. The controller 7 has a built-in control program, and the parameter changes are changed in real time by the display according to the button selection. The electric air pump 1 is installed on the end frame and a protective cover is installed on the outside.

[0027] Working principle: During operation, the charger charges the battery pack 3, the battery pack 3 provides power to the electric air pump 1, the electric air pump 1 stores compressed air into the accumulator 2 through a pipeline, and the nitrogen bag inside the compressed accumulator 2 is inflated. One end of the rescue rope 9 is connected to the traction warhead 8, and the other end is connected to the shoulder-fired launcher 4. The middle part of the rescue rope 9 is spirally wound in the shell of the traction warhead 8. The traction warhead 8 is installed in the launch tube of the shoulder-fired launcher 4, and the air inlet at the end of the traction warhead 8 is connected to the air outlet inside the launch tube. The controller 7 displays the pressure in the accumulator 2 detected by the pressure sensor 6 through the display. Once the working pressure required for normal firing is met, the serial number of the launch tube or the firing order of the traction bullet can be selected through the selection button on the panel of the controller 7. By pulling the trigger switch, the pneumatic control valve can be opened to expand the nitrogen bag in the accumulator 2 and release the compressed air, which enters the traction bullet 8 in the launch tube through the air pipe, pushing the traction bullet 8 to be fired. Before firing, the front and rear positions of the person who fell into the water can be aimed at by the sight 10 for firing. The firing process adopts a projectile method to be dropped near the person who fell into the water. Due to four consecutive shots, the inflation can be completed instantly and the rescue rope 9 can be fired to ensure that the person is quickly rescued.
