Claims

A vertical pipe that is arranged with the pipeline direction vertical and to which fire-extinguishing water is supplied;
A water spray gun having a vertical pipe connected to the upper opening of the vertical pipe so as to be rotatable around a pipe line, and a water spray nozzle connected to the top of the vertical pipe;
A power generation mechanism that generates a reciprocating force using a part of the fire extinguishing water as a drive source;
A power conversion mechanism that converts the reciprocating force generated by the power generation mechanism into a rotational force around an axis orthogonal to the pipe direction of the vertical pipe;
A power transmission mechanism unit that converts the rotational power converted by the power conversion mechanism unit into rotational power around the pipe direction of the vertical pipe and transmits the rotational power to the vertical pipe, and turns the water spray gun;
A swivel-type water spray gun device comprising:

The power generation mechanism is
A cylinder chamber;
Is displaceably arranged in the axial direction in the cylinder chamber, and the partition member to define into a first cylinder chamber and a second cylinder chamber the cylinder chamber in the axial direction,
A water supply port provided in the cylinder chamber for supplying the fire-extinguishing water to the first cylinder chamber;
A drain outlet provided in the cylinder chamber for draining the fire-extinguishing water from the first cylinder chamber;
A rod fixed to the partition member, one end of which extends from the cylinder chamber, and is disposed so as to reciprocate in the axial direction of the cylinder chamber in conjunction with the displacement of the partition member;
A biasing means disposed in the second cylinder chamber and biasing the partition member toward the first cylinder chamber;
The first cylinder chamber is disposed so as to have a water supply closing position for closing the water supply port and a drainage closing position for closing the drainage port, and in conjunction with the reciprocating movement of the rod, A switch valve for switching between the closed position,
The swivel type watering gun apparatus according to claim 1, comprising:

The power conversion mechanism is
A claw wheel fixed to a shaft orthogonal to the pipe direction of the vertical pipe,
The rod is attached to the extending portion of the rod from the cylinder chamber so as to take a first position and a second position, and is engaged with the claw wheel during the forward movement of the rod, and is located at the first position. The claw wheel is rotated by a first predetermined angle around one side of the shaft, and when the claw wheel is located at the second position, the claw wheel is rotated around the first predetermined angle around the shaft. Nails configured to be moved,
The claw is switched from the first position to the second position when the vertical pipe rotates to a side around the pipe direction by a second predetermined angle, and the vertical pipe is moved to the other side around the pipe direction. Claw position switching means for switching the claw from the second position to the first position when rotated by a second predetermined angle;
The swivel-type watering gun apparatus according to claim 2, further comprising:

The power transmission mechanism is
A first bevel gear attached to the vertical pipe in an externally fitted state;
A second bevel gear fixed to the end of the shaft and meshing with the first bevel gear;
The swivel-type watering gun apparatus according to claim 3, comprising:
