[0014] A method for using a drone for firefighting and rescue, comprising the following steps: hooking rescue materials with a hook, controlling the drone to take off, the rescue materials being hung by a wire rope just below the drone under the action of gravity, controlling a first motor to drive a winding shaft to rotate to reel in the wire rope until the rescue materials are between two clamping plates, driving an electric cylinder to extend so that the two clamping plates are clamped on both sides of the rescue materials, at which time a support plate moves to the edge of the bottom of the rescue materials and supports the edge of the bottom of the rescue materials, so that the rescue materials are fixed during the flight of the drone, and the drone flies to a position where the rescue materials are dropped. After the UAV is placed, the electric cylinder is shortened, the splint and the support plate are separated from the rescue materials, and the first motor is controlled to drive the winding shaft to rotate in the opposite direction to release the wire rope, so that the rescue materials are smoothly delivered to the required position. When the UAV is working at the fire scene, if it is found that the surface of the transparent visual window is blocked by soot, the second motor is started to move the slider downward along the lead screw, and the jet pipe and the wiping pad move downward accordingly. The air pump is started to make the jet pipe spray high-pressure airflow to the transparent visual window to perform preliminary cleaning of the transparent visual window. The wiping pad then wipes the residual soot on the surface of the transparent visual window clean, so that the field of view of the high-definition camera is clear.

[0015] The present invention provides a fire rescue drone and a method for using the drone. The drone has the following beneficial effects:

[0016] 1. The firefighting and rescue drone is equipped with an insulation pad and a transparent visual window. The insulation pad is used to block heat and reduce the impact of the heat at the fire rescue site on the drone's internal electronic components. The transparent visual window is used to prevent dust and dirt at the rescue site from adhering to the infrared thermal imager and high-definition camera, which is convenient for cleaning and can further improve the protection of the infrared thermal imager and high-definition camera, thereby extending the service life of the device.

[0017] 2. The fire rescue drone uses a lifting device to lift and drop rescue materials by winding and releasing a wire rope, so that the drone can drop materials in the air to avoid being unable to park the drone in certain narrow rescue locations. Compared with the method of lifting materials with a fixed-length lifting rope commonly used in the prior art, the lifting device is more flexible and convenient for dropping rescue materials to places where it is difficult for drones to land.

[0018] 3. The firefighting and rescue drone cooperates with the lifting device and the fixing device. When the lifting device lifts the rescue materials, the wire rope is reeled in to place the materials between the clamps, and then the clamps of the fixing device are used to clamp the two sides of the rescue materials. At the same time, the support plate can support the edge of the bottom of the rescue materials to disperse the force acting on the wire rope, thereby improving the durability of the wire rope and extending the service life of the wire rope to prevent the wire rope from breaking due to frequent use and causing the carried goods to fall. The rescue materials can also be fixed to prevent the rescue materials from shaking due to being in a hanging state, further improving the safety of the drone in transporting rescue materials.

[0019] 4. The firefighting and rescue drone uses a cleaning device. When soot adheres to the surface of the transparent viewing window, the cleaning device uses the high-pressure airflow ejected from the jet pipe to perform preliminary cleaning of the soot, and the wiping pad then performs secondary cleaning, thereby realizing the function of automatically cleaning the soot, so as to avoid the situation where soot blocks the lens of the high-definition camera during rescue at the fire scene, prevent the lens of the high-definition camera from being blocked, and facilitate the drone to transmit clear fire scene conditions through the high-definition camera.

[0039] A method for using a drone for firefighting and rescue, comprising the following steps: hooking rescue materials with a hook 105, controlling the drone to take off, and under the action of gravity, the rescue materials are hung by a steel wire rope 104 directly below the drone, controlling the first motor 102 to drive the winding shaft 103 to rotate to reel in the steel wire rope 104, until the rescue materials are between two clamping plates 126, driving the electric cylinder 122 to extend, so that the two clamping plates 126 are clamped on both sides of the rescue materials, at this time, the support plate 127 moves to the edge of the bottom of the rescue materials and supports the edge of the bottom of the rescue materials, so that the rescue materials are fixed during the flight of the drone, and after the drone flies to the position for dropping the rescue materials, the electric cylinder 122 is shortened, and the clamping Plate 126 and support plate 127 both leave the rescue materials, and control the first motor 102 to drive the winding shaft 103 to rotate in the opposite direction to release the wire rope 104, so that the rescue materials can be smoothly delivered to the required position. When the drone is working at the fire scene, if it is found that the surface of the transparent visual window 4 is blocked by soot, start the second motor 1303 to make the slider 1305 move downward along the screw 1304, and the jet pipe 1313 and the wiping pad 1307 move downward accordingly, and start the air pump 1311 so that the jet pipe 1313 sprays high-pressure airflow to the transparent visual window 4, and the transparent visual window 4 is preliminarily cleaned, and the wiping pad 1307 then wipes the residual soot on the surface of the transparent visual window 4, so that the field of view of the high-definition camera 6 is clear.

[0040] When in use, by setting a heat insulation pad 3 between the body 1 and the protective shell 2, when the drone is working at the fire scene, the heat of the fire is blocked by the heat insulation pad 3, so that the heat transferred to the body 1 is greatly reduced, reducing the impact of the high temperature at the fire scene on the internal electronic components of the body 1. By setting a transparent visual window 4 in front of the probe of the infrared thermal imager 5 and in front of the lens of the high-definition camera 6, dust and dirt at the rescue site are prevented from adhering to the infrared thermal imager 5 and the high-definition camera 6.

[0041] When lifting the rescue materials through the lifting device 10 and the fixing device 12, the wire rope 104 is extended to a certain length, and the packaged rescue materials are hung on the hook 105, the drone is controlled to take off, and the rescue materials are gradually lifted up under the pull of the wire rope 104. When the rescue materials are hung directly below the drone under the action of gravity, the first motor 102 is started to drive the winding shaft 103 to rotate, and the winding shaft 103 gradually reels the wire rope 104, so that the rescue materials move upward until the rescue materials move between the two clamping plates 126, and the reeling is stopped, and the electric cylinder 122 is controlled to extend, and the U-shaped tube 123, the clamping plate 126 and the support plate 127 are overall close to the rescue materials. Since the end of the U-shaped tube 123 where the first push rod 124 is located is longer than the end where the second push rod 125 is located, the clamping plate 126 contacts the surface of the rescue materials before the support plate 127, and the electric cylinder 122 Continuing to extend, the first push rod 124 is squeezed by the rescue materials and moves inward along the U-shaped tube 123, and the air in the U-shaped tube 123 squeezes the second push rod 125, so that the second push rod 125 extends out of the U-shaped tube 123 until the first push rod 124 moves to the limit position and cannot move further. At this time, the spring 129 is stretched, and the support plate 127 is just at the edge of the lower surface of the rescue materials, so that the support plates 127 of the two sets of fixing devices 12 support both sides of the lower surface of the rescue materials, and at the same time, the two clamps 126 also clamp both sides of the rescue materials, so that the rescue materials are firmly fixed. When the position for dropping materials is reached, the electric cylinder 122 is controlled to shorten, so that the clamps 126 and the support plates 127 leave the rescue materials, and then the first motor 102 is controlled to drive the winding shaft 103 to rotate in the opposite direction, releasing the wire rope 104, so that the rescue materials are slowly placed on the ground.

[0042] Through the cleaning device 13, when ash adheres to the surface of the transparent visual window 4, the two sets of second motors 1303 are started to drive the lead screw 1304 to rotate, and the slider 1305 moves downward along the outer surface of the lead screw 1304, and the connecting shaft 1306, the wiping pad 1307, the air pump 1311, the conduit 1312 and the jet pipe 1313 move downward as a whole, and the air pump 1311 is started to make the jet pipe 1313 spray out a high-pressure airflow. During the downward movement of the jet pipe 1313, the high-pressure airflow blows away most of the ash adhered to the surface of the transparent visual window 4, and the wiping pad 1307 then wipes the remaining ash clean, so that the high-definition camera 6 can clearly shoot the fire scene. The wiping pad 1307 is wound and installed on the connecting shaft 1306 through the adhesive portion 1308. After the use of the drone is finished, the wiping pad 1307 is removed from the connecting shaft 1306, cleaned and then installed back for easy reuse.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.

Under the action of gravity, the rescue materials are hung by the steel wire rope (104) directly below the drone. The first motor (102) is controlled to drive the winding shaft (103) to rotate to reel in the steel wire rope (104) until the rescue materials are between the two clamping plates (126). The electric cylinder (122) is driven to extend, so that the two clamping plates (126) are clamped on both sides of the rescue materials. At this time, the support plate (127) moves to the edge of the bottom of the rescue materials and supports the edge of the bottom of the rescue materials, so that the rescue materials are fixed during the flight of the drone. After the drone flies to the position for dropping the rescue materials, the electric cylinder (122) is shortened, and the clamping plates (126) and the support plate (127) are both away from the rescue materials. The first motor (102) is controlled to drive the winding shaft (103) to rotate in the opposite direction to release the steel wire rope (104), so that the rescue materials can be smoothly delivered to the desired location. When the UAV is working at the fire scene, if it is found that the surface of the transparent visual window (4) is blocked by soot, the second motor (1303) is started to make the slider (1305) move downward along the lead screw (1304), and the jet pipe (1313) and the wiping pad (1307) move downward accordingly. The air pump (1311) is started to make the jet pipe (1313) spray high-pressure airflow toward the transparent visual window (4), and the transparent visual window (4) is preliminarily cleaned. The wiping pad (1307) then wipes the remaining soot on the surface of the transparent visual window (4) clean, so that the field of view of the high-definition camera (6) is clear.
