The front tube 5 is provided with a conical guide block 501 and two helical tubes 502. The guide block 501 is composed of two half guide blocks. It also includes two rods 9, two bundles of pull ropes 11 and a first screw 12. The rods 9 are rotatably disposed in the transition tube 4. The pull ropes 11 connect the rods 9 and the first screw 12. The first screw 12 can be screwed into the threaded holes on the transition tube 4 and the helical tubes 502. In this invention, a small hole is provided at the interface of the front tube 5, and a small hole is provided at the left end of the transition tube 4. One end of the guide rope 6 is knotted, and the other end passes through the small hole and the small hole at the left end of the transition tube 4 to connect with one end of the rescue rope 7 inside the rope tube 2, and is knotted at the connection. After the rescue rope 7 is inserted into the rope tube 2, it passes out from the tail cap 10. When in use, the rescue bomb is placed into the launching tube of the thrower, one end of the rescue rope 7 is connected to the thrower, and the outer wall of the tail cap 10 is attached to the inner wall of the launching tube. When the thrower is working, the water rescue bomb can be launched to the required position.

[0017] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0018] In this embodiment, the tail cap 10 is provided with an oblique hole 101 and a clearance groove 102. The oblique hole 101 and the clearance groove 102 are connected. The other end of the rescue rope 7 passes through the oblique hole 101. After the rescue rope 7 is inserted into the rope tube 2, a certain length of the other end is left. This remaining length is knotted, and the other end of the rescue rope 7 passes through the oblique hole 101. In use, the rescue projectile is placed into the launch tube of the launcher. The outer wall of the tail cap 10 fits against the inner wall of the launch tube. Due to the setting of the oblique hole 101, the air pressure in the launcher will not flow into the rope tube 2, preventing the rope tube 2 from being blown open. At the same time, the rescue rope 7 extends from the clearance groove 102 through the launch tube and connects to the launcher, avoiding gaps between the outer wall of the tail cap 10 and the inner wall of the launch tube. Specifically, the tail cap 10 is provided with an upwardly extending annular protrusion 103. The annular protrusion 103 is made of nylon material to make it elastic.

[0019] In this embodiment, four support rods 401 are provided on the inner wall of the transition tube 4, and the line rod 9 is rotatably mounted on two of the support rods 401. Specifically, the line rod 9 has protrusions at both ends, which are rotatably connected to the support rods 401. In use, the first screw 12 on the transition tube 4 is removed and connected to the screw tube 502. After the lifebuoy in the front tube 5 is inflated, the two half-front tubes separate and fly away. The half-front tubes drive the pull rope 11 to move, and the pull rope 11 on the line rod 9 is released when it rotates. When it is necessary to pull the rope tube 2 back to the surface from the water, one end of the rescue rope 7 can be pulled directly, and the half-front tubes can be retrieved by the pull rope 11.

[0020] In this embodiment, the rope tube 2 is provided with an annular connecting pad 201; it also includes a plurality of second screws 13, which are used to connect the connecting pad 201, the middle tube 3, and the transition tube 4. Specifically, the connecting pad 201 is provided with a threaded hole, and the second screws 13 pass through the middle tube 3 and the transition tube 4 to connect with the threaded hole on the connecting pad 201, thereby fixing the rope tube 2, the middle tube 3, and the transition tube 4 together.

[0021] In this embodiment, the central tube 3 is a carbon fiber central tube. The carbon fiber central tube is lightweight and has high strength, making the land-based rescue missile less prone to damage. In addition, the carbon fiber central tube is lightweight, which can reduce the weight of the land-based rescue missile.
