[0028] Reference Figure 1A non-limiting embodiment of the present invention, a boat interceptor, includes a control valve body 10, a high-pressure gas chamber 2020 and an air pipe 30, wherein the high-pressure gas chamber 20 is connected to the air pipe 30 and the control valve body 10 respectively, the air pipe 30 extends into the high-pressure gas chamber 20 and is sealedly connected to the high-pressure gas chamber 20, the control valve body 10 is located below the high-pressure gas chamber 20, a trigger 13 is provided on the control valve body 10, the control valve body 10 is connected to a gas cylinder assembly 80, specifically, the gas cylinder assembly 80 includes a gas cylinder valve 84 and a high-pressure gas cylinder 81, the control valve body 10 is connected to the high-pressure gas cylinder 81 through the gas cylinder valve 84, the high-pressure gas cylinder 81 is equipped with a high-pressure gas source, the An air rod assembly 60 is installed in the air pipe 30, and the air rod assembly 60 includes an interception head 61 for fixing the interception rope 90. A rope box 73 is fixed to the air pipe 30 through a fixing part 70 with a handle 71. The fixing part 70 is sleeved on the air pipe 30 and fastened to the air pipe 30 by an adjusting screw 72. When it is necessary to adjust the position of the fixing part 70 on the air pipe 30, the adjusting screw 72 is loosened, the fixing part 70 is moved to a suitable position, and then the adjusting screw 72 is tightened to fasten the fixing part 70 to the air pipe 30. The interception rope 90 is a mesh interception structure, one end of the interception rope 90 is fixed on the interception head 61, and the rest is laid in the rope box 73.The boat interceptor of the present invention mainly consists of a high-pressure gas chamber 20, a control valve body 10 and an air pipe 30 respectively connected to the high-pressure gas chamber 20, a high-pressure gas cylinder 81 connected to the control valve body 10, a gas rod assembly 60 with an interception head 61 located in the air pipe 30, an interception rope 90 fixed on the interception head 61, and a rope box 73 installed under the air pipe 30 for placing the interception rope 90. The overall structure has few parts, a simple structure, and a small size, which can be achieved with a specification of 900×110×200mm. In this embodiment, a plurality of holes are opened on the rope box 73, which effectively reduces the overall mass of the interceptor, so that the interceptor is not only small in structure, but also light in weight, and is easy to carry and hold as a whole; the setting of the trigger 13 on the control valve body 10 and the setting of the handle 71 on the fixing member 70, when in use, the operator can use one hand to hold the handle 71, pick up the boat interceptor, aim at the direction of the boat to be intercepted, and place it tilted downward, and the other hand can be used to hold the handle 71 in the direction of the boat to be intercepted.

It can be operated by hand, which is flexible and convenient. Because the interception rope 90 is under the pressure of the high-pressure gas in the gas rod assembly 60, it rushes out of the rope box 73 instantly under the guidance of the gas rod assembly 60. The length of the interception rope 90 is ≥9m, and the interception distance of the interception rope 90 can reach 6m to 18m.
