Description

Technical Field

[0001] The invention relates to the field of fire-fighting robots, and in particular to a portable fire-fighting robot. Background Art

[0002] Firefighting is to eliminate hidden dangers and prevent disasters. It mainly includes the rescue of personnel at the fire scene, the rescue of important facilities and equipment, the safety protection and rescue of important property, and the extinguishing of fires. The purpose is to reduce the degree of damage caused by the fire and reduce casualties and property losses. If special circumstances occur at the fire scene, making it impossible for firefighters or fire trucks to approach and firefighters to understand the situation inside the fire scene, firefighting robots are needed to extinguish the fire inside the fire scene and investigate the internal information of the fire scene.

[0003] After searching, a Chinese patent application with application publication number CN115400375A discloses a light and small portable fire-fighting robot, including a main body, a crawler track is symmetrically installed on the bottom of the main body, a connecting pipe is installed through the rear end of the main body, a fixing ring is installed on the top of the main body, a water tank is installed inside the main body, a water inlet pipe is installed in front of the connecting pipe, a booster pump is installed in front of the water inlet pipe, a water outlet pipe is installed on the top of the booster pump, the water outlet pipe is located inside the fixing ring, a support pipe is installed on one side of the water outlet pipe, a motor is installed inside the support pipe, and a screw motor is installed inside the main body. The present invention is installed with a fixing ring, and the fire-fighting robot is disassembled and transported after the fire is extinguished by the firefighters, the pipe head connecting ring is separated from the connecting ring, and then the fixing bolts installed inside the fixing ring are removed to release the fixing of the fixing ring to the water outlet pipe, and then the water outlet pipe is disconnected from the booster pump.

[0016] The present invention provides a slide rail mechanism, a retracting mechanism and a storage mechanism. When the fire-fighting robot is carried to a fire scene, the cylindrical pin and the latch are respectively taken out from the inside of the slide rail mechanism and the storage mechanism. At this time, the draw-out rod and the draw-out plate are respectively inserted into the inside of the sleeve and the draw-out frame, thereby completing the contraction of the fire-fighting robot, so as to reduce the volume of the fire-fighting robot.

[0017] The present invention provides a water sprinkling mechanism and a pressurizing mechanism. When the fire scene is extinguished by the water sprinkling mechanism, the water inside the water bag is continuously pumped into the water cannon by a pump, and the water cannon sprays the water out, thereby extinguishing the fire scene. During the process, the water sprinkling mechanism vibrates under the action of the spring and the water cannon, so that the water cannon is caused to reciprocate up and down by the vibration, so as to increase the fire extinguishing range of the water cannon. The water cannon squeezes the buffer pad when it reciprocates up and down. At this time, the gas inside the buffer pad is transported to the inside of the conduit through the exhaust pipe after being squeezed, and the gas is sprayed into the inside of the water cannon through the air inlet pipe, so that the air pressure inside the water cannon is increased, and then the water inside the water cannon is quickly sprayed onto the fire source under the action of the air pressure. Since the water flow rate is fast, the force of the water on the fire source is increased, so that the fire source is quickly extinguished under the action of the water pressure, so as to improve the fire extinguishing efficiency of the fire fighting robot.
