Liquid cannon

A liquid cannon for use in discharging a liquid, the liquid cannon comprising:

• a head assembly, a tail assembly, an inlet for the liquid, and a conduit;
• wherein:
• the head assembly comprises:
• a body and a plate connected together to define at least part of a head assembly compartment;
• a nozzle;
• a rotatable conduit portion bearing;
• an access opening;
• and
• a cap configured to connect to the body to cap the access opening;
• the conduit comprises a rotatable conduit portion that is fluidly connected to the nozzle and operably connected to the rotatable conduit portion bearing such that the rotatable conduit portion is rotatable about a first axis of the rotatable conduit portion bearing, thereby accommodating vertical angular movement of the nozzle;
• the conduit extends through the rotatable conduit portion bearing in a direction that is parallel to the first axis;
• the first axis passes through the access opening;
• the head assembly is mounted to a bearing;
• the tail assembly comprises a sleeve defining at least part of a tail assembly compartment, and a mounting portion;
• the mounting portion is configured to be mounted to the bearing such that the head assembly is rotatable with respect to the tail assembly at the bearing;
• the mounting portion is disposed between the sleeve and the body;
• the mounting portion is configured to enable the liquid cannon to be mounted to a structure;
• the conduit provides a flowpath for the liquid between the inlet and the nozzle;
• the conduit passes through the sleeve of the tail assembly, the bearing and the head assembly;
• the head assembly compartment is sealed from an environment of the liquid cannon;
• the tail assembly compartment is sealed from the environment of the liquid cannon;
• and
• at least one of the head assembly compartment and the tail assembly compartment houses a controller that is configured to control a drive means of the liquid cannon to drive movement of the nozzle.
