Abstract

The invention relates to the technical field of ship equipment, and discloses a sand blasting type water cannon structure which comprises a base, an outer connecting cylinder is arranged in the base, an inner connecting cylinder is arranged in the outer connecting cylinder, an annular cavity is formed between the outer connecting cylinder and the inner connecting cylinder, and the lower end of the inner connecting cylinder penetrates through the outer connecting cylinder; the lower end of the outer connecting cylinder is connected with a high-pressure water inlet pipe, and the lower end of the inner connecting cylinder is connected with a high-pressure mortar pipe; a water guide pipe is fixed to the upper end of the outer connecting cylinder, a sand guide pipe is fixed to the upper end of the inner connecting cylinder, a mixing cylinder is arranged between the water guide pipe and the upper end of the sand guide pipe, a slurry outlet cylinder is arranged in the middle of the mixing cylinder, a spray head pipe is connected to the slurry outlet cylinder, and a spray head is arranged at the front end of the spray head pipe. The device has the beneficial effects that mortar and water can be mixed to form a water-sand mixture, the water-sand mixture is sprayed out at a high speed, the pressing effect on a pirate ship is enhanced, and the defensive performance of the ship is enhanced.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a sandblasting water cannon structure. Background technique [0002] With the development of the globalization of the world economy, many ships travel to and from the world's major routes, and pirates are rampant in many sea areas. Since it is usually impossible for commercial ships to be equipped with a large number of armed personnel or equipped with weapon systems, it is usually installed on merchant ships.
