These places are prone to fires due to human or weather reasons. Once a fire occurs, the consequences are disastrous. The fire must be extinguished immediately to prevent the spread of the fire and endanger human life and property safety. Therefore, these areas are equipped with corresponding fire-fighting tools such as fire extinguishers in accordance with national regulations.

[0014] Preferably, a mounting frame is fixed to the upper surface of the roof, and a panoramic camera is installed on the top of the mounting frame.

[0015] Working principle: The electric trolley provides power and supports the structure of the roof. It drives the entire fire extinguishing system when the trolley moves. The water spray assembly is located on the roof and includes a water tank. Water is injected into the water tank through the water inlet. The water tank is connected to a connecting pipe, and a water pump is installed on the roof. The input end of the water pump is connected to the connecting pipe through a pumping pipe. The water in the water tank is extracted and transported to the drain pipe and the delivery pipe. A sealing sleeve is installed on the top of the delivery pipe. A diverter is fixed on the sealing sleeve. Multiple long tubes are installed in the diverter. Nozzles are provided at the ends of these long tubes. When the water pump is started, water reaches the diverter through the delivery pipe and is then sprayed out from the nozzle through the long tube, forming a larger fire extinguishing coverage area. A motor is installed on the outer wall of the delivery pipe. The motor drives gear one to rotate and meshes with gear two on the sealing sleeve, driving the sealing sleeve, diverter and nozzle to rotate, thereby increasing the water spraying range and achieving a wider fire extinguishing effect.

[0016] The fire extinguishing assembly is located on the roof and is fixed and supported by a support plate. A fire extinguisher is installed on the support plate. The output end of the fire extinguisher is connected to a nozzle. A solenoid valve is provided inside the nozzle to control the output of the fire extinguishing agent. A gear three is installed on the outer wall of the fire extinguisher. Gear three is meshed with a rack output by an electric push rod installed on the support block. The rotation of gear three is controlled by the action of the electric push rod, thereby adjusting the angle of the nozzle and improving the accuracy of fire extinguishing.

[0017] The auxiliary component is used to extinguish ground fire and is driven by a hydraulic rod. The output end of the hydraulic rod is connected to a connecting block. A connecting plate 1 is installed on the connecting block. The connecting plate 1 is fixed to the connecting plate 2 by bolts. A flame-retardant fire blanket 1 is fixed on the connecting plate 2. When the electric trolley moves, the hydraulic rod can drive the flame-retardant fire blanket 1 to move on the ground to achieve the effect of covering and extinguishing the ground fire. In addition, a motor 2 is installed on the support seat on the outer wall of the trolley. The motor 2 drives the winding roller to rotate through the rotating rod. The winding roller is fixed with a connecting plate 3 and a flame-retardant fire blanket 2. The motor 2 can control the unfolding and winding of the flame-retardant fire blanket 2 to further enhance the fire extinguishing effect of the ground fire.

[0018] The control component is located on the roof and is connected to each module through a controller. The lidar module is responsible for scanning the three-dimensional environmental information of the fire scene to achieve real-time positioning and path planning. The GPS positioning module provides precise location information to ensure the accurate position perception of the unmanned vehicle at the fire scene. The wireless communication and remote control module allows the unmanned vehicle to conduct real-time data transmission and remote control with the remote command center. The alarm module is used to issue an alarm when there is an abnormal situation at the fire scene to ensure the safety of personnel. A panoramic camera is also installed on the mounting frame to monitor the image data of the fire scene in real time, assist in positioning and fire source identification, improve the intelligence level of the fire-fighting unmanned vehicle, and achieve the beneficial effects of efficient fire-fighting and safe navigation.

[0019] The present invention provides an unmanned fire-fighting vehicle with positioning and navigation functions. It has the following beneficial effects:

[0020] 1. The present invention achieves the effect of increasing the fire extinguishing range by the coordination between the internal structures of the nozzle assembly and the rotation of gear 1 by the motor, thereby driving gear 2 and the nozzle to rotate, thereby solving the technical problems of limited coverage and low fire extinguishing efficiency of existing fire extinguishing devices.

[0021] 2. The present invention achieves the convenience of navigation of the vehicle and improves the fire extinguishing effect through the coordination between the control component and the fire extinguishing component, thereby solving the problem of insufficient navigation accuracy and poor fire extinguishing effect of existing small-sized fire extinguishing vehicles in complex environments.

[0022] 3. The present invention achieves coordination between the internal structures of the auxiliary components and the mutual coordination between the flame retardant fire blanket 2 and the flame retardant fire blanket 1. When the trolley moves, the flame retardant fire blanket 2 and the flame retardant fire blanket 1 move with them to quickly extinguish the ground fire, thus solving the technical bottleneck of low efficiency of traditional fire extinguishing methods in handling ground fires and the risk of secondary combustion during fire extinguishing.
