Law enforcement water cannon for ship

Abstract

The invention discloses a law enforcement water cannon for a ship. A steering device is arranged between a base and a cannon body, the steering device can control the law enforcement water cannon to rotate horizontally; the cannon body is arranged in a roundabout shape, and a tilting device for controlling the angle of a cannon head is arranged between the cannon body and the cannon head; the canon head comprises an elbow pipe, the tilting device is connected to one end of the elbow pipe, and a rectifying section is connected to the other end of the elbow pipe; a steady flow speed increasing section and a steady flow jetting section are arranged at the right end of the rectifying section in sequence; an arc-shaped guide pipe is arranged in the elbow pipe; a rectifying plate is arranged atthe left end of the rectifying section, and a flow straightener is arranged at the right end of the rectifying section; and the steady flow speed increasing section is arranged in a taper shape to increase flow rate of the water cannon, and the steady flow jetting section is arranged in a taper shape, and the taper of the steady flow jetting section is smaller than the taper of the steady flow speed increasing section. The law enforcement water cannon has a simple structure, the design is ingenious, a large amount of turbulence flow generated by passing through corners of the cannon body is effectively eliminated to enable the turbulence intensity of water columns jetted by the water cannon to be the lowest, the range of the water cannon is increased, the range of impacting is expanded, the water column forming effect is optimized, the strength of beating is strengthened, and promotion of application value is great.

Description

technical field [0001] The invention relates to the field of water cannons, in particular to a marine law enforcement water cannon. Background technique [0002] Existing law enforcement methods for domestic official ships often use forcibly approaching the vessel being enforced, and the law enforcement personnel jump onto the vessel being enforced to directly control the subject of law enforcement; There are hidden dangers in the safety of the targets; with the emphasis and development of maritime rights protection, most of the new domestic official ships are equipped with law enforcement water cannon devices, which implement long-distance expulsion and soft strikes against illegal ships to maintain the sovereignty of my country's territorial waters; currently my country's official ships are installed Most of the law enforcement water cannons are refitted from land-use fire-fighting water cannons. However, the range of land-use fire-fighting water cannons is small and the bea...

[0002] Existing law enforcement methods for domestic official ships often use forcibly approaching the vessel being enforced, and the law enforcement officers jump onto the vessel being enforced to directly control the subject of law enforcement; There are hidden dangers in the safety of the targets; with the emphasis and development of maritime rights protection, most of the newly built domestic official ships are equipped with law enforcement water cannon devices, which implement long-distance expulsion and soft strikes against illegal ships to maintain the sovereignty of my country's territorial waters; Most of the law enforcement water cannons are modified from land-use fire-fighting water cannons. However, the range of land-use fire-fighting water cannons is small and the beating power is not strong. Therefore, it is necessary to design a water cannon with a long range of water cannons and strong beating power of the water column.
