Spherical core rotary type fire monitor

A ball core rotary type fire monitor comprises a base, a water inlet pipe and a horizontal rotary body which are sequentially connected, the top of the horizontal rotary body is sequentially connected with a short pipe and a monitor head through an elbow, and a first ball core assembly and a second ball core assembly which are communicated with each other are rotationally arranged in the short pipe; a pitching driving assembly is arranged on the outer wall of the short pipe and connected with the first ball core assembly and the second ball core assembly. The first ball core assembly and the second ball core assembly are arranged in the short pipe and matched with the elbow, an elbow pipe in the prior art is replaced, pipeline bending is reduced, in addition, in the pitching action process, the position of the first ball core assembly is fixed, the short pipe and the second ball core assembly rotate relative to the first ball core assembly, and therefore the pitching action is more stable. And the pipe diamet
