Firefighting robot with flame detection and automatic water-spraying fire extinguishing functions

Abstract

A fire-fighting robot with flame sensing and automatic water spraying functions includes a shell, an ultrasonic sensor, a battery box, a circuit module, a motor, wheels, a flame sensor, casters, and a nozzle. The motor, wheels, and casters are located on the lower surface of the shell; the circuit module and battery box are located above the lower surface; the nozzle is located above the upper surface; and the ultrasonic sensor and flame sensor are mounted at the front of the shell. The ultrasonic sensor, flame sensor, motor, and battery box are electrically connected to the circuit module via connecting cables.

Claims

1. A fire-fighting robot with flame sensing and automatic water spraying functions, comprising: A housing, at least one flame sensor, at least one distance sensor, a water spray device, at least one circuit module, at least one battery box, at least one motor, a plurality of wheels, and a plurality of connecting wires for electrically connecting the components. The device is characterized by the following features: the outer shell is a hollow structure for housing the circuit module and the battery box; the plurality of wheels and motors are located at the bottom of the outer shell, connected to each other, and driven by at least one motor, enabling the fire-fighting robot to move on the ground; the flame sensor is used to detect the presence of flame signals in the environment and transmits the sensing signals to the circuit module through the connecting cable assembly; the distance sensor is used to sense the distance between the fire-fighting robot and the object or fire source in front, and transmits the distance information to the circuit module through the connecting cable assembly; based on the sensing results of the flame sensor and the distance sensor, the circuit module controls the operation of at least one motor through the connecting cable assembly, enabling the fire-fighting robot to approach the fire source, and when preset conditions are met, the water spray device located on the front or upper side of the outer shell is activated through the connecting cable assembly to spray water towards the fire source for fire extinguishing.

2. The fire-fighting robot with flame sensing and automatic water spraying functions as described in claim 1, wherein, The distance sensor is an ultrasonic sensor.

3. A fire-fighting robot with flame sensing and automatic water spraying functions as described in claim 1, wherein, The plurality of wheels includes at least one drive wheel and at least one omnidirectional wheel to improve the stability of the firefighting robot when it moves.

4. A fire-fighting robot with flame sensing and automatic water spraying functions as described in claim 1, wherein, The water spraying device includes a nozzle, which is located on the front or upper side of the housing, and its start and stop are controlled by the circuit module through the connecting wire assembly.

5. A fire-fighting robot with flame sensing and automatic water spraying functions as described in claim 1, wherein, The circuit module controls the movement of the fire-fighting robot by connecting wires based on the direction of the flame sensed by the flame sensor, causing it to move toward the fire source.

6. A fire-fighting robot with flame sensing and automatic water spraying functions as described in claim 1, wherein, When the circuit module determines that the fire-fighting robot has approached the fire source to a preset distance, it controls at least one motor to stop via the connecting wire assembly and activates the water spray device to extinguish the fire.

7. A fire-fighting robot with flame sensing and automatic water spraying functions as described in claim 1, wherein, The outer shell is made of heat-resistant plastic, metal, or a combination thereof.
