[0002] With the application of drones in various fields, by deploying special drones to specific working environments, the influence of environmental factors is greatly overcome. Among them, forest fire-fighting drones belong to one of the special equipment and play an important role in the process of forest fire monitoring.

[0003] In the prior art, a patent document with the publication number of CN215043703U discloses a forest fire-fighting drone with a smoke alarm structure, including a drone body and a mounting frame. The two sides of the drone body are installed with movable connecting rods. The lower end of the drone body is fixed with a support frame. The upper part of the movable frame is installed with a movable block. The lower end of the movable frame is fixed with a fixed ball. The mounting frame is installed at the lower end of the fixed cylinder. The lower end of the support frame is fixed with a storage net box. The two sides inside the chain are provided with linkage rods.

[0004] During use, it is found that the smoke detector in the above device is still exposed to the outside in the shutdown state, and it is easy to be impacted by foreign objects. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a forest fire-fighting drone.

[0006] A forest fire fighting drone of the present invention includes a drone main body, propellers, support rods, a support plate and a protective box. Multiple groups of propellers are arranged on the drone main body. Four groups of support rods are arranged at the bottom end of the drone main body. The bottom ends of two groups of support rods on the same side are both connected to the top end of a support plate. A protective box is installed at the bottom end of the drone main body. It also includes a fire monitoring component, a transmission component and a traction component. Traction components are arranged on two groups of support rods on the same side. The fire monitoring component is installed inside the protective box. Each traction component respectively pulls and moves the fire monitoring component through a transmission component. A square opening is arranged at the bottom end of the protective box. During use, multiple groups of propellers rotate synchronously, so that the drone main body takes off. When the drone main body takes off, the two traction components respectively pass through the transmission components to make the fire monitoring component move through the square opening to below the protective box, so that the fire detection component detects the forest fire situation in the air. After the monitoring is completed, when the drone main body lands, the self-weight of the drone main body enables the traction component to reversely pull the fire monitoring component through the corresponding transmission component, so that the fire monitoring component re-enters the protective box through the square opening. Through the takeoff and landing of the drone main body, the traction component and the transmission component cooperate to realize the movement of the fire monitoring component, improving the convenience and at the same time enhancing the safety protection of the fire monitoring component.

[0007] Preferably, the fire monitoring component includes a light bar, a first spring, a first lifting plate, a mounting seat and a fire detector. Two groups of light bars are longitudinally and fixedly installed inside the protective box. The first lifting plate is slidably connected to the two light bars. A first spring is sleeved outside each light bar. Both first springs are above the first lifting plate. A mounting seat is arranged at the bottom end of the first lifting plate. A fire detector is installed at the bottom end of the mounting seat. When the drone main body takes off through the propellers, the traction component releases the pulling on the top end of the first lifting plate through the corresponding transmission component. At the same time, the first lifting plate moves downward along the light bars under the action of the elastic force of the two first springs, so that the first lifting plate drives the fire detector to move through the mounting seat, so that the fire detector moves through the square opening to below the protective box. The fire detector monitors the forest fire situation. When the drone main body lands, the self-gravity of the drone main body enables the traction component to pull the first lifting plate upward through the transmission component, so that the first lifting plate rises along the two light bars while the two first springs are compressed, realizing that the fire detector automatically extends to below the protective box when the drone main body takes off, and when the drone main body lands, the fire detector automatically enters the protective box through the square opening.

[0008] Preferably, the traction assembly includes a strip-shaped opening, a second spring, a second lifting plate, a support rod, and a conical head. A set of strip-shaped openings are respectively provided on two sets of support rods on the same side. A round hole is provided on the second lifting plate. The second lifting plate is slidably connected to the two sets of support rods through the round hole. A set of cross plates are respectively installed in each set of round holes. Each set of cross plates are respectively slidably arranged in a strip-shaped opening. A set of second springs are respectively installed between the top end of each set of cross plates and the top end of the strip-shaped opening. A support rod is respectively provided at the bottom end of each set of second lifting plates. Each set of support rods are respectively slidably connected to a set of support plates. A set of conical heads are respectively installed at the bottom end of each set of support rods. A transmission assembly is provided between the second lifting plate and the top end of the first lifting plate; when the UAV body takes off into the air by the rotation of multiple sets of propellers, multiple sets of second springs cooperate with each other to push the corresponding cross plates downward, further causing the cross plates to drive the second lifting plate to move downward. When the second lifting plate moves downward, the second lifting plate releases the pulling on the top end of the first lifting plate through the transmission assembly, so that the first lifting plate drives the mounting seat and the fire detector to move downward under the elastic force of the first spring and the fire detector moves to below the protective box through the square opening. When the UAV body lands on the ground, multiple sets of conical heads contact the ground to reduce sliding. At the same time, the self-weight of the UAV body causes the conical heads to drive the support rods to move upward, so that while the cross plates compress the second springs, the second lifting plate pulls the top end of the first lifting plate through the transmission assembly, further causing the fire detector to re-enter the protective box through the square opening for protection, improving convenience and safety protection performance.

[0009] Preferably, the transmission assembly includes a first bracket, a first guide wheel, a second bracket, a second guide wheel, a third bracket, a third guide wheel, and a rope. The first bracket is installed at the top end of the protective box. The first guide wheel is provided on the first bracket. A set of second brackets and a set of third brackets are respectively provided at the outer end of the protective box. The second guide wheel is installed on the second bracket. The third guide wheel is installed on the third bracket. One end of the rope is connected to the top end of the first lifting plate. The rope bypasses the top end of the first guide wheel and the top end of the second guide wheel and bypasses the bottom end of the third guide wheel and is connected to one end of the second lifting plate; when the UAV body takes off into the air through the propellers, the second lifting plate releases the pulling on the top end of the first lifting plate along the guiding of the third guide wheel, the second guide wheel, and the first guide wheel under the elastic force of the second spring. At the same time, the first lifting plate drives the fire detector to extend below the protective box through the square opening under the elastic force of the first spring. When the UAV body lands on the ground, the conical head and the support rod drive the second lifting plate to rise, so that the second lifting plate pulls the first lifting plate upward through the rope under the cooperation of the third guide wheel, the second guide wheel, and the first guide wheel, thereby realizing the automatic exhibition and storage protection of the fire detector.

[0010] Preferably, the sealing assembly includes a first shaft pin, a sealing door, a second shaft pin, a connecting rod, and a third shaft pin. One end of each of the two sealing doors is hinged to the bottom end of the protection box through a set of first shaft pins. One end of each of the two connecting rods is hinged to one end of each of the two sealing doors through a set of second shaft pins. The other ends of the two connecting rods are respectively hinged to one end of the mounting base through a set of third shaft pins. During use, when the first lifting plate drives the mounting base and the fire detector to move downward, the mounting base, under the cooperation of the two sets of first shaft pins, two sets of second shaft pins, two sets of connecting rods, and two sets of third shaft pins, releases the sealing of the other's opening by the two sealing doors, so that the fire detector moves to the lower part of the protection box through the square opening. When the first lifting plate drives the mounting base and the fire detector into the protection box, the mounting base pulls the two sealing doors through the two connecting rods, so that when the fire detector enters the protection box, the two sealing doors seal the square opening, further improving the safety protection performance.

[0011] Preferably, it further includes a fixing base, a wing nut, a second annular flat washer, and a strip groove. A set of fixing bases are respectively installed at the front and rear ends of the second lifting plate. A set of wing nuts are respectively screwed on each set of fixing bases. A set of second annular flat washers are respectively sleeved on each set of wing nuts. A set of strip grooves are respectively arranged on each set of support rods. When the UAV body needs to be moved, the staff rotates the wing nut, so that the wing nut enters the strip groove and tightly fixes the strip groove, preventing the fire detector from moving out when the UAV body is moved, improving the convenience.

[0012] Preferably, it further includes a maintenance plate, a first bolt, a first annular flat washer, and an observation window. There is a maintenance opening at the front end of the protection box. The maintenance plate is installed at the front end of the protection box through the first bolt. A set of first annular flat washers are respectively sleeved on each set of first bolts. An observation window is installed on the maintenance plate. The staff observes the internal situation of the protection box through the observation window, releases the locking of the maintenance plate by the first bolt, and the staff performs maintenance on the inside through the maintenance opening, improving the convenience.

[0013] Preferably, it further includes an anti-slip pad. A set of anti-slip pads are respectively arranged at the bottom end of each support plate. The support plate stably supports the UAV body in cooperation with the anti-slip pad, improving the stability.

[0014] Preferably, it further includes weight-reducing holes. Multiple sets of weight-reducing holes are arranged on each support plate. The weight-reducing holes reduce the weight of the overall device and reduce the power consumption.

[0015] Preferably, the fire detector is a high-resolution camera, an infrared camera, a multi-spectral imager, or a thermal imager.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: When in use, multiple sets of propellers rotate synchronously, so that the UAV body takes off. When the UAV body takes off, two sets of traction components respectively drive the fire monitoring component to move to the lower part of the protection box through the transmission component via the square opening, so that the fire detection component detects the forest fire situation in the air. After the monitoring is completed, when the UAV body lands, the self-weight of the UAV body enables the traction component to reversely traction the fire monitoring component through the corresponding power transmission component, so that the fire monitoring component re-enters the protection box through the square opening. Through the take-off and landing of the UAV body, the cooperation between the traction component and the transmission component realizes the movement of the fire monitoring component, improving the convenience and at the same time enhancing the safety protection of the fire monitoring component.

[0023] In this embodiment, when the UAV body 101 takes off by the rotation of multiple sets of propellers 102, multiple sets of second springs 302 cooperate with each other to push the corresponding cross plate 304 downward, further causing the cross plate 304 to drive the second lifting plate 303 to move downward.
