Visual insulating spray lance for live working

A visual insulating spray lance for live working, comprising:

• a spray nozzle having an inlet;
• a hollow operating rod, the hollow operating rod including a top opening and a bottom opening;
• a liquid guide tube arranged in the hollow operating rod, the liquid guide tube having an outlet end extending out of the top opening of the hollow operating rod and an opposite end extending out of the bottom opening;
• an air tube arranged in the hollow operating, the air tube having an outlet end extending out of the top opening of the hollow operating tube and an opposite end extending out of the bottom opening;
• a connecting tube inserted into an upper end of the hollow operating rod, the connecting tube communicating with the inlet of the spray nozzle;
• an upward connecting rod connectively hinged to an upper portion of the hollow operating rod via a first fastener, the upward connecting rod having an upper end fixedly provided with a video optical transceiver;
• a display fixedly arranged on a lower portion of the hollow operating rod via a second fastener, the display comprising a shell and an internal circuit, the internal circuit comprising an optical receiver, a chip for a video signal processor, a power divider, a display screen, and a 4G communication module, wherein the chip for the video signal processor has an input terminal connected to a signal output terminal of the optical receiver and an output terminal connected to an input terminal of the power divider, two output interfaces of the power divider are respectively connected to an interface of the display screen and an RS232 interface of the 4G communication module;
• an optical fiber tube arranged in the hollow operating rod;
• an optical fiber arranged in an internal cavity of the upward connecting rod and in the optical fiber tube, the optical fiber connecting the video optical transceiver to the display,
• the optical fiber being connected to the optical receiver via a fiber channel (FC) interface;
• a battery connected to the optical receiver, the chip for a video signal processor, the power divider, the display screen, a power terminal of the 4G communication module, and a power terminal of a global positioning system (GPS) module;
• and
• a charging port connected to the battery is formed in the shell.
