DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] According to Figures 1 - 3 As shown, it includes a bottom plate 1. A motor 11 is installed at a position on the top end of the bottom plate 1 near the other side, and the output end of the motor 11 is drivingly connected to a rotating rod 12. One end of the rotating rod 12 is installed with a limiting plate 13 through a bearing, and the bottom end of the limiting plate 13 is installed with the top end of the bottom plate 1.

[0020] A throwing device body 2 is installed at a position on the top end of the bottom plate 1 near one side. The throwing device body 2 includes a launching bottle 20. The bottom end of the launching bottle 20 is installed with the top end of the bottom plate 1. One end of the launching bottle 20 is installed with a gun body 21. An installation plate 22 is installed on the outer surface of the gun body 21 near the top end. A safety pin 23 is movably inserted into the interior of the installation plate 22. The top end of the safety pin 23 is installed with an installation disc 24, and a hand-held rod 25 is installed on the top end of the installation disc 24.

[0021] A piston rod 32 is movably arranged inside the gun body 21. One end of the piston rod 32 is installed with a fixed disc 3. A pin hole 31 is opened at a position on the side surface of the fixed disc 3 near the top end. A connecting rope 33 is installed at a position on the side surface of the fixed disc 3 near the bottom end. One end of the connecting rope 33 is movably wound around the outer surface of the rotating rod 12. The outer diameter of the safety pin 23 is adapted to the inner diameter of the pin hole 31, and the bottom end of the safety pin 23 extends into the interior of the pin hole 31 and is arranged in a limiting and clamping manner with it. A placing cylinder 34 is installed on one side of the fixed disc 3. A sealing piston 37 is movably arranged inside the placing cylinder 34. One end of the sealing piston 37 is installed with a sealing cover 36. A pulling rod 38 is installed on one side of the sealing cover 36. Floating plates 35 are installed on both sides of the side surface of the placing cylinder 34.

[0022] When someone falls into the water in rivers, lakes and other waters, the rescue personnel can place the bottom plate 1 on the road beside the water area. At this time, the rescue items can be placed inside the placement cylinder 34, and then the sealing piston 37 is inserted into the inside of the placement cylinder 34 through the pulling rod 38, so that the inside of the placement cylinder 34 can be sealed by the sealing cover 36 and the sealing piston 37. After that, the user can move the mounting plate 24 upward through the hand-held rod 25, so that the safety pin 23 can move upward inside the pin hole 31 and move out of the inside of the safety pin 23. The setting of the safety pin 23 and the pin hole 31 can effectively solve the problem that the existing life-saving throwing device does not have any safety mechanism, so that the life-saving throwing device is prone to accidental throwing during use, so that the life-saving throwing device cannot accurately perform the launching operation. At the same time, the launching bottle 20 can be started. Under the operation of the launching bottle 20, the gas inside the launching bottle 20 and the gun body 21 will be compressed and released, so that the piston rod 32 can be pushed out of the gun body 21, so that the fixed plate 3 and the placement cylinder 34 can be thrown into the water area. At the same time, the connecting rope 33 wound around the outer surface of the rotating rod 12 will be released accordingly, so that the rotating rod 12 can rotate accordingly. Due to the setting of two floating plates 35 on the outer surface of the placement cylinder 34, when the placement cylinder 34 falls into the water area, it will float horizontally under the action of the two floating plates 35. At this time, the rescue personnel in the water can grab the placement cylinder 34, and then take out the sealing cover 36 and the sealing piston 37 from the inside of the placement cylinder 34 through the pulling rod 38, so that the rescue personnel can take out the rescue items placed inside the placement cylinder 34 and perform rescue operations. After that, the user can place the sealing cover 36 and the sealing piston 37 back inside the placement cylinder 34 through the pulling rod 38. At this time, the rescue personnel on the shore can start the motor 11. Under the operation of the motor 11, the rotating rod 12 can rotate accordingly, so that the connecting rope 33 can be wound around the outer surface of the rotating rod 12, so that the fixed plate 3 and the placement cylinder 34 can be pulled back from the water area.

[0023] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
