Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting drones, and in particular to a fire-fighting structure and a fire-fighting method for a plateau fire-fighting drone. Background Art

[0002] With global climate change, forest and grassland fires, and other types of fires, are becoming increasingly frequent. Plateau regions feature complex terrain and harsh climate conditions, with dry and flammable vegetation. Once a fire breaks out, it spreads rapidly. Furthermore, due to the rugged terrain and inaccessible transportation, traditional ground-based firefighting forces struggle to quickly reach and effectively control the fire, often leading to the expansion of the fire and causing significant ecological and property damage. The plateau features complex terrain, including mountains and canyons, with rugged roads. Large ground-based firefighting equipment, such as fire trucks, has difficulty navigating the area, resulting in long arrival times and potentially delaying the optimal firefighting opportunity. For example, in mountainous areas, narrow and steep roads make it difficult for fire trucks to quickly navigate, and damaged roads can prevent them from reaching the fire source. Consequently, drones are often used for firefighting.

[0003] At present, the fire extinguishing structure of the UAV cannot adjust the spray range of the fire extinguishing agent during use, resulting in a limited fire extinguishing range. When the UAV itself is used for adjustment, the camera will shake, which is not conducive to observing the fire extinguishing situation. Moreover, the fire extinguishing method is single, resulting in low fire extinguishing efficiency, making the fire easy to increase and unable to meet the use requirements. Therefore, we propose a fire extinguishing structure and fire extinguishing method for plateau fire fighting UAVs. Summary of the Invention

When the drone itself is used for adjustment, it will cause the camera to shake, which is not conducive to observing the fire extinguishing situation. Moreover, the fire extinguishing method is single, resulting in low fire extinguishing efficiency, making it easy for the fire to increase and unable to meet the use requirements.

One side of the adjusting frame is fixedly connected to the atomizing nozzle, the top of the right side of the fire extinguishing agent tank is fixedly connected to the motor, the front and back of the fire extinguishing agent tank are fixedly connected to the material box, one side of the material box is movably connected to a material guide roller, a baffle is provided on the outside of the material guide roller, the top of the baffle is fixedly connected to the material box, the right side of the material guide roller is fixedly connected to a rotating shaft, and a hollow tube is provided at the bottom of the rotating shaft, the right side of the inner cavity of the hollow tube is fixedly connected to a spring, one side of the spring is fixedly connected to a sealing disk, and the left side of the sealing disk is fixedly connected to a pushing rod, the inside of the hollow tube is connected to an exhaust pipe, and one side of the exhaust pipe is connected to an air pump.

[0006] Preferably, a filter box is fixedly connected to the right side of the bottom of the fire extinguishing agent box, and a HEPA high-efficiency filter plate and an activated carbon filter plate are sequentially connected to the bottom of the filter box from left to right. The left side of the filter box is connected to a fan, and the left side of the fan is connected to a smoking pipe, and one side of the smoking pipe is connected to a smoking head, the right side of the filter box is connected to an air duct, and the left side of the air duct is connected to a connector, and a camera is fixedly connected to one side of the body.

[0009] Preferably, a movable door is movably connected to one side of the material box, and a material guide groove is provided on the surface of the material guide roller.

[0010] Preferably, the surface of the rotating shaft is movably connected to a vertical plate via a bearing, one side of the vertical plate is fixedly connected to the material box, and the bottom of the inner cavity of the vertical plate is fixedly connected to the hollow tube.

[0011] Preferably, the output end of the motor and the right side of the rotating shaft are both fixedly connected with a synchronous wheel, and a synchronous belt is engaged on the surface of the synchronous wheel.

[0012] Preferably, one side of the fan is fixedly connected to a support base, and one side of the support base is fixedly connected to the fire extinguishing agent tank.

[0013] Preferably, a rectangular groove is provided at the bottom of the inner cavity of the filter box, and a sealing ring is fixedly connected to the inner cavity of the rectangular groove.

[0014] A fire extinguishing method for a plateau firefighting drone comprises the following steps:

[0015] A. First, inject the fire extinguishing agent into the inner cavity of the fire extinguishing agent tank, place the fire extinguishing bomb in the inner cavity of the tank, move it to the fire extinguishing position, and control the material pump through the remote controller to extract the fire extinguishing agent through the extraction pipe, and then spray the fire extinguishing agent through the bellows and atomizing nozzle. At the same time, the motor will be started, and the motor will drive the gear to rotate. The gear plate cooperates with the gear plate, so that the gear will move during the rotation process, and then drive the motor to move. The motor drives the adjustment frame to move, and the adjustment frame drives the atomizing nozzle to move, so that the working range can be adjusted to achieve a good fire extinguishing effect.

[0016] B. Secondly, the motor is started, causing the shaft to rotate, which in turn drives the guide roller to rotate. After the guide roller rotates 180 degrees, the guide trough is aligned with the fire extinguishing bomb, causing the fire extinguishing bomb at the bottom to move into the inner cavity of the guide trough. The guide roller is then controlled to rotate 180 degrees again, causing the fire extinguishing bomb to align with the push rod. The air pump is then started, rapidly discharging gas into the inner cavity of the hollow tube through the exhaust pipe. As the gas on the right side of the hollow tube cavity increases rapidly, it pushes the sealing disk to move rapidly, which drives the push rod to move rapidly, thereby pushing the fire extinguishing bomb out and moving it to the fire location.

[0017] C. Finally, before extinguishing the fire, the fan will be started to draw in the smoke from the outside through the smoke pipe and the smoke head, and then discharged into the inner cavity of the filter box. The smoke is filtered through the HEPA high-efficiency filter plate and the activated carbon filter plate in turn, and then the gas is discharged through the air duct and the connector, thereby speeding up the air flow rate in front of the camera, making it easier for the camera to record the fire situation.

[0018] Compared with the prior art, the present invention provides a fire extinguishing structure and method for a plateau firefighting drone, which has the following beneficial effects:

[0019] The present invention can spray fire extinguishing agent to extinguish fire through the cooperation of material pump, extraction pipe, bellows and atomizing nozzle. At the same time, the motor drives gears, tooth plates and other structures to move the atomizing nozzle, expand the working range, improve the fire extinguishing effect, cover the fire source more comprehensively, and enhance the efficiency and pertinence of fire extinguishing. It is equipped with components such as material box, guide roller and air pump, which can release fire extinguishing bombs. Combined with fire extinguishing agent spraying, it provides a variety of fire extinguishing means to adapt to different plateau fire scenes and enhance the ability to deal with complex fire situations. It uses fans, smoke pipes, filter boxes and HEPA high-efficiency filter plates, activated carbon filter plates, etc. to extract and filter smoke at the fire scene, speed up the air flow rate in front of the camera, reduce smoke obstruction, and enable the camera to clearly capture the fire situation, which is convenient for operators to accurately grasp the fire situation and provide a reliable basis for fire extinguishing decision-making.

[0037] A fire extinguishing method for a plateau firefighting drone comprises the following steps:

[0038] A. First, inject the fire extinguishing agent into the inner cavity of the fire extinguishing agent tank 2, place the fire extinguishing bomb in the inner cavity of the material box 13, and move it to the fire extinguishing position.
