Description

Technical Field

[0001] The utility model relates to the technical field of laser obstacle clearing instruments, in particular to a laser drone for extinguishing tree crown fires. Background Art

[0002] Laser obstacle remover is a device that uses the highly focused and high-power density characteristics of laser beams to act on tree trunks, causing them to evaporate and explode locally due to high temperature and high pressure, thereby cutting trees. It can be used to cut tree trunks in tree isolation zones to extinguish forest crown fires.

[0003] At present, a general portable laser obstacle clearer is composed of modules such as a laser host, a mobile power supply, a laser focusing lens, a tripod and a controller. The laser focusing lens is placed on the ground on a tripod to cut tree trunks, which makes the field of view of the laser focusing lens standing on the ground easily blocked by forest trees. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A laser drone for extinguishing tree crown fires, comprising a tree-cutting laser cannon, with a load-carrying drone connected above the tree-cutting laser cannon;

[0007] A camera is arranged below the main body shell of the load-carrying UAV, and the camera is arranged parallel to the outer wall of the tree-cutting laser cannon.

[0008] Preferably, the tree-cutting laser cannon is connected to a laser host via a wire, the laser host is arranged in a main body shell of the load-carrying drone, a mobile power supply is arranged in the main body shell of the load-carrying drone, and the mobile power supply and the laser host are connected via a wire.

[0009] Preferably, a bottom cover is fixedly installed below the inner cavity of the main body shell of the load-carrying drone, a servo motor 1 is installed below the bottom cover, an output shaft 1 in the servo motor 1 is fixedly installed with a connecting rod through a coupling, and the end of the connecting rod is fixedly connected to the tree-cutting laser cannon.

[0012] Preferably, a positioning laser pen is fixedly connected between the tree-cutting laser cannon and the camera.

[0013] Compared with the prior art, the utility model provides a laser drone for extinguishing crown fires, which has the following beneficial effects:

[0014] 1. The laser drone for extinguishing crown fire uses a load-carrying drone to carry a tree-cutting laser cannon at high altitude, which is faster and more convenient than the movement of the tree-cutting laser cannon on the forest ground. Then, with the camera installed under the load-carrying drone, the tree-cutting laser cannon above the forest can obtain a wider field of view, and can observe the spread of the crown fire more clearly. According to the spread of the crown fire, the tree-cutting laser cannon can be moved quickly, and the laser emitted by the tree-cutting laser cannon can cut the trees to form a fire-fighting isolation zone.

[0015] 2. The crown fire extinguishing laser drone can display the route of the laser cutting emitted by the tree-cutting laser cannon in advance by positioning the laser emitted by the laser pen, that is, the tree-cutting laser cannon can locate the cutting part in advance, and then turn on the tree-cutting laser cannon to emit laser to cut the tree trunk. When the laser displayed in advance by the positioning laser pen deviates from the required cutting position, the output shaft 2 of the servo 2 can drive the servo 1, the connecting rod and the tree-cutting laser cannon to rotate horizontally, thereby adjusting the horizontal cutting position of the tree-cutting laser cannon, and then the output of the output shaft 1 in the servo 1 can drive the connecting rod and the tree-cutting laser cannon to rotate vertically, thereby adjusting the vertical cutting position of the tree-cutting laser cannon.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Reference Figure 1-3 A laser drone for extinguishing tree crown fires includes a load-carrying drone 1. The load-carrying drone 1 in the present application is improved based on the SY800 type six-rotor large-load transport drone in the prior art. First, the surface of the main shell of the load-carrying drone 1 adopts a streamlined design to reduce wind resistance. Second, obstacle protection rings for protecting the rotors are arranged around the six rotors of the SY800 type six-rotor large-load transport drone. The obstacle protection rings are in a circular ring shape and are arranged around the rotors to mainly prevent branches from contacting the rotors. The obstacle protection rings are fixedly connected to the frame of the six-rotor large-load transport drone.

[0023] In this embodiment, a tree-cutting laser cannon 5 is arranged under the load-carrying drone 1. The tree-cutting laser cannon 5 is specifically a laser focusing lens of a DW8130 portable laser obstacle clearer. The head end of the tree-cutting laser cannon 5 is connected to a laser host 11 through a wire. The laser host 11 is also connected to a mobile power supply 12 through a wire. The mobile power supply 12 and the laser host 11 are both fixedly connected to the main body shell of the load-carrying drone 1.

[0024] In this embodiment, a bottom cover 2 is fixedly installed below the inner cavity of the main shell of the load-carrying drone 1 by multiple screws, and a plurality of slot columns 9 are fixedly installed above the bottom cover 2. The mobile power supply 12 and the laser host 11 are fixedly connected to the upper ends of the plurality of slot columns 9 respectively.

[0025] In this embodiment, a servo 2 10 is fixedly installed above the bottom cover 2, and an output shaft 2 in the servo 2 10 is vertically downward. A servo 1 3 is rotatably installed below the bottom cover 2. The output shaft 2 in the servo 2 10 is fixedly connected to the servo 1 3 through a coupling, and an output shaft 1 8 of the servo 1 3 is vertically fixedly connected to a connecting rod 4 through a coupling. The lower end of the connecting rod 4 is fixedly connected to the tree-cutting laser cannon 5 through bolts.

[0026] In this embodiment, a camera 6 is fixedly installed below the tree-cutting laser cannon 5, and a positioning laser pen 7 is fixedly installed between the camera 6 and the tree-cutting laser cannon 5. The positioning laser pen 7, the camera 6 and the tree-cutting laser cannon 5 are parallel to each other, and the positioning laser pen 7, the camera 6 and the tree-cutting laser cannon 5 are close to each other, so that the laser emitted by the positioning laser pen 7 can be used as the cutting path of the tree-cutting laser cannon 5. The camera 6 is carried at high altitude by the load-carrying drone 1 for high-altitude monitoring, and the tree trunks that need to be cut can be found more clearly. The laser emitted by the positioning laser pen 7 is used to locate the tree trunks that need to be cut, and the laser emitted by the tree-cutting laser cannon 5 is used to cut the tree trunks. The servo 1 3, the camera 6, the positioning laser pen 7 and the servo 2 10 are respectively connected to the mobile power supply 12 through wires.

[0027] The utility model uses a load-carrying drone 1 to carry a tree-cutting laser cannon 5 at high altitude, without the obstruction of forest trees, and the movement of the tree-cutting laser cannon 5 on the forest ground is faster and more convenient. Then, in conjunction with a camera 6 installed below the load-carrying drone 1, a wider field of view can be obtained, and the spread of the crown fire can be observed more clearly. According to the spread of the crown fire, the tree-cutting laser cannon 5 can be quickly moved, and the laser emitted by the tree-cutting laser cannon 5 can cut the trees to form a fire-fighting isolation zone.

[0028] For parts that require precise cutting, such as tree trunks around electric wires, the laser emitted by the existing positioning laser pen 7 can display in advance the route of the laser cutting emitted by the tree-cutting laser cannon 5, that is, the tree-cutting laser cannon 5 can locate the cutting part in advance, and then turn on the tree-cutting laser cannon 5 to emit laser to cut the tree trunk. When the laser displayed in advance by the positioning laser pen 7 deviates from the required cutting position, the output shaft 2 of the servo 2 10 can drive the servo 1 3, the connecting rod 4 and the tree-cutting laser cannon 5 to rotate horizontally, thereby adjusting the horizontal cutting position of the tree-cutting laser cannon 5, and then the output of the output shaft 1 8 in the servo 1 3 can drive the connecting rod 4 and the tree-cutting laser cannon 5 to rotate vertically, thereby adjusting the vertical cutting position of the tree-cutting laser cannon 5.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
