Description

Technical Field

[0002] Traditional firefighting equipment has many limitations in practical applications, especially in complex buildings and large warehouses, where its lack of mobility is particularly prominent, often making it difficult to quickly reach the core of a fire. During firefighting operations, the equipment's spray angle and height adjustment flexibility is poor, limiting the extinguishing range and preventing precise coverage of fire sources in different locations. Furthermore, fire source location relies mainly on manual observation or single detection methods, which are easily affected by environmental factors such as smoke and light, directly impacting firefighting efficiency due to insufficient positioning accuracy. In addition, traditional equipment is highly dependent on firefighters' operation; in dangerous environments such as high temperatures and dense smoke, firefighters must work at close range, facing high safety risks, making it difficult to meet the demands of modern, diverse firefighting for efficiency, safety, and intelligence.

[0052] The working principle and usage process of this invention are as follows: Upon system startup, the battery 21 of the power supply system 2 converts the high-voltage output to multiple voltage levels via a DC-DC converter 22 to power various components. The circuit breaker 27 provides overcurrent protection. The control board 23 receives instructions transmitted from the remote control center via a wireless router 29 and a switch 24, coordinating the operation of each system. The AGV mobile platform 1 activates the laser radar and ultrasonic sensors based on the signal from the control board 23, enabling autonomous path planning and obstacle avoidance. It flexibly moves to the fire scene in complex environments. Upon arrival, the first and second fire-finding cameras 51 and 52 of the fire-finding camera system 5 begin operation. The visible light camera captures images of the scene, while the infrared thermal imaging camera penetrates smoke to detect high-temperature areas. The dual-camera data is transmitted to the control board 23 via signal lines. The system industrial control computer 38 analyzes and processes the data to determine the precise location and height of the fire source. Based on the fire source positioning data, the system industrial control computer 38 sends lifting commands to the control board 23. The multi-section telescopic structure of the electric screw of the lifting mechanism 4 is precisely adjusted under the feedback of the displacement sensor. The height is adjusted, driving the nozzle adjustment frame 45 and nozzle 41 to the designated position. At the same time, the guide wheel 311 assists the automatic telescopic high-pressure water drum 33 in extending and retracting the water pipe synchronously with the lifting. The water supply system 3 starts the DC high-pressure washer 313, and the solenoid valve 37 and contactor 39 are opened. The fire extinguishing water in the water tank 31 enters the DC high-pressure washer 313 through the drain pipe 32 for pressurization, and is then delivered to the nozzle 41 through the automatic telescopic high-pressure water drum 33. The system industrial control computer 38 adjusts the water pressure and flow rate based on the real-time data from the liquid level sensor 312 and pressure sensor 36. The nozzle 41 adjusts the spray angle through the rotating shaft. The water baffle 42 and the cloud enclosure 43 prevent water splashing, achieving precise fire extinguishing. During the operation, the network hard disk recorder 28 continuously stores the on-site video and operation data, and the wireless router 29 maintains the communication link with the remote control center, supporting manual intervention and data monitoring. After the fire is extinguished, the control board 23 coordinates the reset of each system, and the AGV mobile platform 1 autonomously returns to the standby position. The entire process realizes fully automated operation from autonomous movement, fire source detection, height adjustment to precise spraying.

[0053] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
