Chengli Technology Innovation — Chengli fire-fighting robot, Chengli fire series firefighting tank, smoke exhaust, fire suppression, monitoring, remote control. This fire robot is used in conjunction with Chengli Weiwei brand fire trucks, effectively avoiding casualties during fire rescue operations and preventing emergencies caused by explosions triggered by fires.

(1) Fire-fighting Robot Overview
Applications: Fire suppression in subways, highways, underground facilities and freight yards, railway tunnels, petrochemical refineries and oil depots. For situations involving toxic gas leaks, large-area smoke, and flammable/explosive accidents where personnel cannot easily approach, it performs on-site rescue, camera monitoring, hazardous material removal and transport, or obstacle clearing.

(2) Function Introduction
Fault Diagnosis: Real-time online monitoring of the smoke-exhaust firefighting vehicle's working status (smoke exhaust and firefighting system, main unit, wireless communication, camera, etc.), with timely fault alarms and proactive safety measures. Image Acquisition: 1080P HD low-latency image transmission, real-time on-site footage playback, smooth images. Provides clear images for the rescue command center to help commanders make correct and reasonable rescue plans. Transmission distance up to 200m. PTZ Control: Camera horizontal and vertical angle motion control, horizontal 0~360° range, vertical 0~180° range, camera focus, zoom in/out operations; PTZ equipped with infrared night vision. Spray Mechanism Control: Mist cannon, water cannon, and foam cannon vertical angle control, vertical angle 0~45°, controllable water cannon multiple spray patterns (spray, straight stream).
Obstacle Clearing: Hydraulic push blade clears road obstacles at explosion sites; pushes sand and soil at disaster sites to create firebreaks.
Backup Hydraulic Power: Backup hydraulic port can drive external hydraulic components for emergency rescue operations, such as drainage pumps, hydraulic breaking tools, hydraulic lifting equipment, and hydraulic smoke exhaust fans. Lighting and Warning System: Front-mounted lighting provides necessary illumination for rescue sites.
