When the foam bomb is triggered and launched, the bomb body ruptures during the flight or after reaching the target location, and the foam fire extinguishing agent is released. The foam fire extinguishing agent will expand rapidly to form a large amount of foam. These foams can cover the surface of the burning object and extinguish the fire by isolating oxygen.

[0012] The beneficial effects of the present invention are as follows:
[0013] 1. The present invention is provided with a spraying component.

At the same time, when the water flow continues to enter the inner cavity of the spray pipe, the water flow continuously impacts the movable frame, so that the movable frame drives the scrapers on both sides to move on the guide rod, thereby contacting and moving with the inner wall of the spray pipe. The water flow itself may carry various impurities, such as mud, dust, etc. These impurities will be deposited on the pipe wall due to changes in water flow speed when passing through the spray pipe.
[0015] 3. The present invention provides a buffer mechanism. When the external water pipe stops supplying water to the spray pipe, the movable frame is pulled by the reset of the first spring, driving the movable frame to reset and move on the guide rod, so that the side of the movable frame collides with the buffer plate. At the same time, when the buffer plate and the movable frame are squeezed and pressed against each other, the buffer plate can slide on the inner side of the buffer frame through the buffer rod. At the same time, the buffering work of the second spring is used to avoid excessive impact force between the movable frame and the buffer plate, which will cause impact damage to the side of the movable frame.
[0016] 4. The present invention is provided with a throwing component. When it is necessary to extinguish some fire sources that are difficult to access, the throwing tube is driven by the rotating component through the manipulation of the rotating component. After it is rotated to a suitable throwing angle, the foam bomb is put into the throwing tube by pulling the discharge mechanism. At the same time, by opening the electric hydraulic cylinder, the output end of the electric hydraulic cylinder drives the second magnet to move inside the throwing tube toward one end of the bracket through the pulling rod. Since the first magnet and the second magnet are attracted to each other, the second magnet drives the first magnet to move in the inner cavity of the throwing tube. At the same time, the ejection plate is driven by the first magnet through the round rod to slide on the inner side of the round plate. At the same time, the first magnet pulls the third spring to move, and the output end of the electric hydraulic cylinder continuously drives the second magnet to move. The second magnet is driven to move by pulling the rod. When the pulling force is greater than the attraction between the second magnet and the first magnet, the third spring drives the first magnet to separate from the second magnet. At the same time, the resetting pulling force of the third spring causes the first magnet to drive the ejection plate through the round rod to collide with the foam bomb in the inner cavity of the throwing tube, and throw the foam bomb toward the fire point. When the foam bomb is triggered and launched, the bomb body ruptures during the flight or after arriving at the target location, and the foam fire extinguishing agent is released. The foam fire extinguishing agent will expand rapidly to form a large amount of foam. These foams can cover the surface of the burning object and extinguish the fire by isolating it from oxygen. At the same time, the foam also has a certain cooling effect, which can reduce the temperature of the burning object, thereby achieving the purpose of extinguishing the fire.

The connecting frame 685 is pulled back by the fourth spring 687 and moves inside the discharge housing 681 through the round rod 611, so that the connecting frame 685 drives the baffle 683 and the limit plate 689 to reset and move, so that the through hole 684 is concentric with the discharge chute 6811, so that the foam bullets dropped on the baffle 683 pass through the through hole 684 and enter the throwing tube 61, so that the subsequent feeding work can be carried out;
[0037] The specific workflow is as follows:
[0038] During operation, after adding a large amount of water to the water tank 3 for storage, the operator uses wireless communication equipment, such as a radio remote control or sends instructions through a computer network system in a safe area. After the main body 1 receives the instruction, the driving motor drives the crawler component 2 to move and go to the designated location of the fire scene. It is equipped with a sensor system, including a temperature sensor, a smoke sensor, a flame sensor, etc., which can sense the surrounding environment in real time, such as the temperature of the fire, the position and intensity of the flame, and other information, and feed back these data to the operator to better formulate a fire extinguishing strategy. Through remote control, the rotating component 4 is rotated and adjusted, and the spraying component 5 is used to spray water to extinguish the fire. When the fire point is far away and there are a lot of obstacles around the fire point that hinder the movement of the robot, the throwing component 6 can be controlled to throw foam bombs to the fire point to extinguish the fire;
[0039] When a small-scale fire occurs at the fire point, the fire-fighting robot body 1 is moved to a suitable position by remote control, and the water pump 54 is turned on by control, so that the water pump 54 sends water in the water tank 3 to the sprinkler mechanism 53 through the water pipe 55 and the rotating pipe 56, and the water is sprayed out through the sprinkler mechanism 53 to effectively extinguish the fire;
[0040] When the fire-fighting robot body 1 continues to perform fire-fighting work, it can be connected and fixed to the connecting port 534 through the external water pipe 55, and at the same time continue to enter the sprinkler pipe 531 through the one-way valve 535, so as to be sprayed out through the regulating head 532, so as to continue to extinguish the fire at the fire point. At the same time, when the water flow continues to enter the inner cavity of the sprinkler pipe 531, the water flow continuously impacts the movable frame 539, so that the movable frame 539 drives the scrapers 5310 on both sides to move on the guide rod 538, so as to contact and move with the inner wall of the sprinkler pipe 531. The water flow itself may carry various impurities, such as mud, dust, etc. These impurities will be deposited on the pipe wall due to the change in water flow speed when passing through the sprinkler pipe 531. In addition, the pipeline Dust and other debris in the surrounding environment may also enter the pipe through the pipe joints and other parts and adhere to the pipe wall. As time goes by, these impurities and dirt will accumulate and increase, which will also have an adverse effect on the normal operation of the spraying operation, thereby causing pipe blockage or corrosion, affecting the uniformity of the spraying and the fire extinguishing effect. When the fire extinguishing work is completed, the external water pipe 55 stops supplying water to the spray pipe 531, and the movable frame 539 is pulled by the reset of the first spring 5311 to drive the movable plate to move within the inner wall of the spray pipe 531. At the same time, the scrapers 5310 on both sides of the movable plate clean the inner wall of the spray pipe 531. At the same time, the reset of the first spring 5311 drives the movable frame 539 and the buffer mechanism 536 to reset and offset each other.
[0041] When the external water pipe 55 stops supplying water to the spray pipe 531, the movable frame 539 is pulled back by the first spring 5311 to drive the movable frame 539 to reset on the guide rod 538, so that the side of the movable frame 539 collides with the buffer plate 5364. At the same time, when the buffer plate 5364 and the movable frame 539 are squeezed and pressed against each other, the buffer plate 5364 can slide inside the buffer frame 5361 through the buffer rod 5363. At the same time, the second spring 5365 works as a buffer, thereby preventing the collision force between the movable frame 539 and the buffer plate 5364 from being too large, which would cause impact damage to the side of the movable frame 539.
[0042] When it is necessary to extinguish a fire that is difficult to access, the rotating part 4 is manipulated to drive the throwing tube 61 through the rotating part 4. After it is rotated to a suitable throwing angle, the foam bomb is put into the throwing tube 61 by pulling the discharge mechanism 68. At the same time, the electric hydraulic cylinder 63 is opened, and the output end of the electric hydraulic cylinder 63 drives the second magnet 610 to move inside the throwing tube 61 toward one end of the bracket 62 through the pulling rod 64. Since the first magnet 69 and the second magnet 610 are attracted to each other, the second magnet 610 drives the first magnet 69 to move in the inner cavity of the throwing tube 61. At the same time, the first magnet 69 drives the ejection plate 66 through the round rod 611 to slide on the inner side of the circular plate 65. At the same time, the first magnet 69 pulls the third spring 67 to move, and the output of the electric hydraulic cylinder 63 The end continues to drive the second magnet 610 to move by pulling the rod 64. When the pulling force is greater than the attraction between the second magnet 610 and the first magnet 69, the third spring 67 drives the first magnet 69 to separate from the second magnet 610. At the same time, the resetting pulling force of the third spring 67 enables the first magnet 69 to drive the ejection plate 66 through the round rod 611 to collide with the foam bomb in the inner cavity of the throwing tube 61, and throw the foam bomb toward the fire point. When the foam bomb is triggered and launched, the bomb body ruptures during the flight or after reaching the target location, and the foam fire extinguishing agent is released. The foam fire extinguishing agent will expand rapidly to form a large amount of foam. These foams can cover the surface of the burning object and extinguish the fire by isolating oxygen. At the same time, the foam also has a certain cooling effect, which can reduce the temperature of the burning object, thereby achieving the purpose of extinguishing the fire.
[0043] After the foam bomb in the inner cavity of the throwing tube 61 is thrown, the connecting frame 685 is pulled to move in the sliding groove 682, and the connecting frame 685 drives the baffle 683 to move in the moving groove 688 to the side close to the electric hydraulic cylinder 63. At the same time, the connecting frame 685 drives the limit plate 689 to slide on the inner side of the discharge shell 681, and at the same time, the connecting frame 685 is continuously pulled until the through hole 6810 is concentric with the discharge groove 6811, and the gap between the bottom of the limit plate 689 and the top of the baffle 683 is the height of a foam bomb, so that the discharge groove 6811 is When the foam bombs stacked vertically in sequence are against the top of the baffle 683 through the discharge trough 6811 and the through hole 684, the connecting frame 685 is loosened, and the connecting frame 685 is pulled by the reset of the fourth spring 687 and moves inside the discharge shell 681 through the round rod 611, so that the connecting frame 685 drives the baffle 683 and the limit plate 689 to reset and move, so that the through hole 684 is concentric with the discharge trough 6811, so that the foam bombs dropped on the baffle 683 enter the throwing tube 61 through the through hole 684, so as to carry out the subsequent feeding work.
