Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0039] Example 1: Figures 1-13 As shown, this embodiment provides a stair-climbing robot, including: a robot body 1; a fire extinguishing mechanism 2, which performs fire extinguishing operations; and a safe area construction mechanism 3, which quickly builds a safe area at the fire scene to provide oxygen and cool down the affected people.

[0040] In this embodiment, the robot body 1 moves freely on the ground, and the camera on the robot body 1 performs visual detection and patrols the surrounding area; the robot body 1 can enter the elevator, enter different floors, and perform fire inspections on the entire high-rise building. It should be noted that: the robot body 1 is a tracked robot and can move freely. This is a conventional technical means in this field and will not be described in detail here.

[0041] The safety area construction mechanism 3 includes: a robotic arm 301, which is installed on the robot body 1; a heavy block 302, which is placed on the robot body 1; and an oxygen supply component 31, a telescopic cooling component 32 and an adsorption fixing component 33 are provided on the heavy block 302.

[0042] The oxygen supply assembly 31 includes: a nitrogen and oxygen separator 311, which is installed in the robot body 1; a accommodating cavity 3021, with multiple accommodating cavities 3021 opened in the heavy block 302; a reel 312, which is rotatably installed in the accommodating cavity 3021; ​​an oxygen supply pipe 313, which is wound on the reel 312, and the nitrogen and oxygen separator 311 is connected to the heavy block 302 through a connecting pipe 314, which includes an oxygen chamber 3141, an air chamber 3142 and a water flow chamber 3143; a suction nozzle 315 is provided on the oxygen supply pipe 313, and the oxygen chamber 3141 and the air chamber 3142 are connected to the nitrogen and oxygen separator 311. The nitrogen and oxygen separator 311 is a prior art (such as an oxygen generator, a nitrogen generator) and is not described in detail here.

[0043] The telescopic cooling assembly 32 includes: a fixed sleeve 321, which is installed on the heavy block 302; a sliding rod 322, with multiple sliding rods 322 arranged in the fixed sleeve 321; a sliding sleeve 323, which is installed in the sliding rod 322, and a receiving groove 3022 is provided in the heavy block 302, in which the sliding rod 322 slides, the water flow cavity 3143 is connected to the receiving groove 3022, and a plurality of water spray holes 3231 are provided on the sliding sleeve 323.

[0044] In this embodiment, when the camera detects a fire, the robot body 1 first moves away from the fire. The robot arm 301 places the heavy block 302 placed on the robot body 1 on the ground. This area is a safe area. The heavy block 302 is connected to the ground through the adsorption fixing component 33. The robot body 1 then moves to the fire location to extinguish the fire.

[0045] Air enters the nitrogen-oxygen separator 311 through the air cavity 3142 (at the heavy block 302). The nitrogen-oxygen separator 311 separates the oxygen and nitrogen in the air. The oxygen is then discharged through the oxygen cavity 3141 and the oxygen supply pipe 313. Disaster victims in a safe area manually pick up the suction nozzle 315 and place it in their mouth for oxygen supply. The connecting pipe 314 must meet a certain length, with the excess length stored within the robot body 1. Specifically, the oxygen flows from the nitrogen-oxygen separator 311 to the oxygen cavity 3141 to the unwinding shaft 312 and then to the oxygen supply pipe 313. The unwinding shaft 312 has an air supply groove. The oxygen cavity 3141 and the ends of the unwinding shaft 312 are rotatably sealed and connected, connecting the oxygen cavity 3141, the air supply groove, and the oxygen supply pipe 313.

[0046] The adsorption and fixing component 33 includes: a mounting sleeve 331, which is mounted on the bottom of the heavy block 302, and a slide groove 3311 is provided in the mounting sleeve 331; a moving rod 332, which is slidably arranged in the slide groove 3311, and a through cavity 3321 is provided in the moving rod 332; a flexible adsorption block 333, which is mounted on the bottom of the moving rod 332, and an elastic connecting member a334 is provided in the slide groove 3311, and the elastic connecting member a334 conflicts with the moving rod 332, and a one-way valve 335 is provided on the moving rod 332.

[0047] The robotic arm 301 places the heavy block 302 placed on the robot body 1 on the ground. The robotic arm 301 presses the heavy block 302 downward, and the elastic connector a334 is compressed, which discharges the air in the chute 3311 and the through cavity 3321 along the one-way valve 335. The robotic arm 301 leaves the heavy block 302. Under the elastic force of the elastic connector a334, the chute 3311 and the through cavity 3321 are negatively pressurized, facilitating a negative pressure adsorption connection between the flexible adsorption block 333 and the ground.

[0048] At the same time, the water in the water tank 402 is pumped into the water flow chamber 3143, and then the water flows into the receiving groove 3022, driving the multiple sliding rods 322 and the sliding sleeves 323 to move upward. Then the water flows upward along the water spray hole 3231 to cool down the safe area, so that the affected people are located in the safe area and can wait for subsequent rescue.

[0049] The fire extinguishing mechanism 2 includes a mounting block 201 mounted on the robot body 1; a rotating rod 202 is rotatably provided on the mounting block 201, a fire extinguisher 203 and a bevel gear a204 are mounted on the rotating rod 202, a rotating driving member a205 is mounted on the robot body 1, a bevel gear b206 is mounted on the output end of the rotating driving member a205, and the bevel gear a204 is meshed with the bevel gear b206.

[0050] Example 2: Figures 1-13 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0051] This embodiment further includes a water supply mechanism 4, which supplies water from the faucet to the water tank 402. The water supply mechanism 4 includes: a support frame 401, which is mounted on the robot body 1; a water tank 402, which is mounted within the robot body 1; a water inlet pipe 403, which is mounted on the water tank 402; a connector 404, which is mounted on the water inlet pipe 403; a plurality of mounting slots 4041 defined within the connector 404; an elastic connector b405, which is mounted within the mounting slots 4041; and a limiting ball 406, which is mounted at the free end of the elastic connector b405. The water flow chamber 3143 is connected to the water tank 402.

[0052] In this embodiment, the robot body 1 moves to the faucet, the robotic arm 301 clamps the joint 404 on the support frame 401, inserts the joint 404 into the water outlet of the faucet, and the elastic connector b405 drives the limiting ball 406 to be stuck in the water outlet of the faucet. The robotic arm 301 opens the faucet, and the water flows along the water inlet pipe 403 into the water tank 402, realizing the replenishment of the water source.

[0053] The fire extinguisher 203 is provided with a plurality of nozzles a207 and a plurality of nozzles b208 , wherein the plurality of nozzles a207 are arranged in a ring shape outside the plurality of nozzles b208 , and further includes a switching component 21 .

[0054] The switching assembly 21 includes: a fixed plate 211, which is installed on the robot body 1; a rotating driving member b212, which is installed in the robot body 1; a rotating disk 213, which is provided with an output end of the rotating driving member b212, an exhaust pipe 214 is provided between the rotating disk 213 and the nitrogen oxygen separator 311, a drain pipe 215 is provided between the water tank 402 and the rotating disk 213, the fixed plate 211 and the nozzle a207 are connected by a first pipe 216, and the fixed plate 211 and the nozzle b208 are connected by a second pipe 217.

[0055] In this embodiment, air enters the nitrogen-oxygen separator 311 through the air cavity 3142 (at the heavy block 302), and the nitrogen-oxygen separator 311 separates oxygen and nitrogen in the air, and the nitrogen is discharged into the exhaust pipe 214. The rotating driving member b212 drives the rotating disk 213 to achieve communication between the exhaust pipe 214 and the first pipe 216, and between the drain pipe 215 and the second pipe 217. At this time, the nitrogen is ejected along the exhaust pipe 214, the first pipe 216, and the nozzle a207, and the water in the water tank 402 is ejected along the drain pipe 215, the second pipe 217, and the nozzle b208.

[0056] The rotating drive member b212 drives the rotating disk 213 to connect the exhaust pipe 214 with the second pipe 217 and the drain pipe 215 with the first pipe 216; at this time, nitrogen is ejected along the exhaust pipe 214, the second pipe 217, and the nozzle b208, and the water in the water tank 402 is ejected along the drain pipe 215, the first pipe 216, and the nozzle a207.

[0057] It should be noted that this embodiment uses a combined fire extinguishing method of water and nitrogen, which is sprayed through nozzles a207 and b208 to facilitate fire extinguishing operations in different situations. Nozzle a207 is located at the outermost layer, and multiple nozzles b208 are arranged within the multiple nozzles a207. Nozzles b208 spray water to extinguish the fire. When nozzles a207 spray nitrogen, the nitrogen is located outside the water flow and forms an air shield barrier to prevent air from entering the fire, thereby enhancing the fire extinguishing effect.

[0058] When it is necessary to extinguish a fire on electrical equipment, nozzle b208 sprays nitrogen to reduce the oxygen concentration at the fire point, thereby extinguishing the fire at the fire point. Nozzle a207 sprays water to form a water barrier on the outside of the electrical equipment to extinguish the fire around the electrical equipment and prevent the high temperature of the surrounding flames from causing the electrical equipment to reignite.

[0059] It is important to note that this embodiment can achieve an unlimited supply of fire extinguishing materials. Nitrogen is directly obtained from the air, which can achieve an unlimited supply of nitrogen. When there is a tap at the fire, water can be replenished, achieving an unlimited supply of water flow. A power pump is provided in the robot body 1 to achieve power supply.

[0060] Working steps

[0061] Step one, inspection process: the robot body 1 moves freely on the ground, the camera on the robot body 1 conducts visual inspection, and the surrounding area is inspected; the robot body 1 can enter the elevator and enter different floors to conduct fire inspection of the entire high-rise building;

[0062] Step two, safety area construction process: when the camera discovers a fire, the robot body 1 first moves away from the fire, and the heavy block 302 placed on the robot body 1 is placed on the ground by the mechanical arm 301. This area is a safety area, and the heavy block 302 is connected to the ground through the adsorption fixing assembly 33. The robot body 1 moves to the fire site for fire extinguishing;

[0063] Air enters the nitrogen-oxygen separator 311 through the air cavity 3142 (at the heavy block 302), and the nitrogen-oxygen separator 311 separates oxygen and nitrogen in the air. Oxygen is discharged through the oxygen cavity 3141 and the oxygen supply pipe 313. The affected personnel are in the safety area, manually pick up the suction nozzle 315 and place it in the mouth for oxygen supply;

[0064] Step three, water source supply process: the robot body 1 moves to the faucet, the mechanical arm 301 clamps the connector 404 on the support frame 401, and the connector 404 is inserted into the water outlet end of the faucet. The elastic connecting piece b 405 drives the limiting ball 406 to be clamped in the water outlet end of the faucet. The mechanical arm 301 opens the faucet, and the water flow enters the water tank 402 along the water inlet pipe 403 to realize the supply of water source;

[0065] Step four, fire extinguishing process: air enters the nitrogen-oxygen separator 311 through the air cavity 3142 (at the heavy block 302), and the nitrogen-oxygen separator 311 separates oxygen and nitrogen in the air. Nitrogen is discharged into the exhaust pipe 214. The rotary drive b 212 drives the rotary disc 213 to realize the communication between the exhaust pipe 214 and the first pipe 216, and the communication between the drain pipe 215 and the second pipe 217. At this time, nitrogen is sprayed along the exhaust pipe 214, the first pipe 216, and the nozzle a 207. The water flow in the water tank 402 is sprayed along the drain pipe 215, the second pipe 217, and the nozzle b 208.

[0066] The rotary drive b 212 drives the rotary disc 213 to realize the communication between the exhaust pipe 214 and the second pipe 217, and the communication between the drain pipe 215 and the first pipe 216. At this time, nitrogen is sprayed along the exhaust pipe 214, the second pipe 217, and the nozzle b 208. The water flow in the water tank 402 is sprayed along the drain pipe 215, the first pipe 216, and the nozzle a 207.

[0067] It should be noted that: the water, nitrogen combination fire extinguishing mode is used in the embodiment, and is sprayed through the nozzle a207 and the nozzle b208, so that the fire extinguishing operation can be performed under different conditions. The nozzle a207 is located at the outermost layer, and the plurality of nozzle b208 is arranged in the plurality of nozzle a207. The nozzle b208 sprays water flow to the fire point for fire extinguishing operation. When the nozzle a207 sprays nitrogen, the nitrogen is located outside the water flow, the sprayed nitrogen forms a gas shielding barrier to block the air from entering the fire point, and the fire extinguishing effect is enhanced.

[0068] When the electrical equipment needs to be extinguished, the nozzle b208 sprays nitrogen to reduce the oxygen concentration at the fire point, and then the fire point is extinguished. The nozzle a207 sprays water flow to form a water flow barrier outside the electrical equipment, and the surrounding electrical equipment is extinguished to avoid the high temperature of the surrounding flame to make the electrical equipment re-ignite.

[0069] The above only describes the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
