DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , where Figure 1Schematic diagram of a preferred embodiment of a fire - fighting unmanned aerial vehicle provided by the present utility model; Figure 2 is Figure 1 Front view of a fire - fighting unmanned aerial vehicle as shown; Figure 3 is Figure 1 Front view of a protective frame in a fire - fighting unmanned aerial vehicle as shown; Figure 4 is Figure 1 Front view of a sprinkler head in a fire - fighting unmanned aerial vehicle as shown. A fire - fighting unmanned aerial vehicle includes a chassis 1. Inside the chassis 1, a rotating motor 2 is fixedly installed. A regulating column 3 is fixedly sleeved on the output shaft of the rotating motor 2. A water tank 4 is fixedly sleeved inside the chassis 1. A water pump 5 is fixedly installed at the bottom of the inner cavity of the chassis 1. A corrugated pipe 6 is fixedly sleeved on the top of the water pump 5. One end of the corrugated pipe 6 is fixedly installed with a sprinkler head 7. A searchlight 8 is fixedly installed at the bottom of the chassis 1. A storage battery 9 is fixedly installed inside the chassis 1. A control host 10 is fixedly installed on the top of the storage battery 9. A power mechanism 11 is arranged on the top of the chassis 1. A protective frame 12 is fixedly installed on the top of the chassis 1. A support column 13 is movably sleeved at the bottom of the chassis 1. An anti - slip sleeve 14 is fixedly sleeved at one end of the support column 13. A sealing cover 15 is threadedly sleeved on the top of the water tank 4. An auxiliary mechanism 16 is arranged at the bottom of the water tank 4.

[0028] The sprinkler head 7 is fixedly connected to the side of the regulating column 3, and the number of the sprinkler heads 7 is three. By setting the sprinkler head 7, when the unmanned aerial vehicle is sprinkling water for fire - fighting, the sprinkler head 7 is opened and the rotating motor 2 is started, so that the rotating motor 2 can drive the three sprinkler heads 7 to turn through the regulating column 3, that is, the adjustment effect of the sprinkling angles of the three sprinkler heads 7 is achieved, thereby avoiding the problem that the adjustment of the sprinkling angle requires the movement of the unmanned aerial vehicle for adjustment, resulting in a more complex fire - fighting operation, and thus improving the practicability of the fire - fighting unmanned aerial vehicle.

[0029] The bottom of the sprinkler head 7 is movably sleeved at the bottom of the inner cavity of the chassis 1, and the sprinkler head 7 is perpendicular to the regulating column 3. By setting the sprinkler head 7, when sprinkling water for fire - fighting, the water pump 5 is started, so that the water pump 5 can suck the water flow inside the water tank 4, and then convey it to the inside of the sprinkler head 7 through the corrugated pipe 6, improving the flow velocity of the water flow, that is, improving the spraying lift of the water flow, and thus improving the spraying distance of the water flow.

[0030] The number of the searchlights 8 is two, and the two searchlights 8 are symmetrically distributed with the chassis 1 as the axis of symmetry. By setting the searchlights 8, when carrying out fire - fighting operations at night, the searchlights 8 are started, so that the searchlights 8 can illuminate the area below the chassis 1, that is, the marking effect of the position of the chassis 1 is achieved, and thus it brings convenience to the night control of the unmanned aerial vehicle.

[0031] The power mechanism 11 includes a positioning block 111. The positioning block 111 is fixedly connected to the top of the chassis 1. A rotary motor 112 is fixedly installed at the bottom of the positioning block 111. A rotor 113 is fixedly sleeved on the output shaft of the rotary motor 112. By setting the power mechanism 11, when the drone is used for sprinkler fire extinguishing, the rotary motor 112 is started, so that the rotary motor 112 drives the rotor 113 to rotate rapidly, and the four rotors 113 drive the water tank 4 to rise through the chassis 1, thereby achieving the effect of lifting and conveying water flow.

[0032] The protective frame 12 is located directly above the chassis 1, and the material of the protective frame 12 is carbon fiber material. By setting the protective frame 12, when carrying out forest fire extinguishing operations, the protective frame 12 can limit the position of the chassis 1, avoiding the problem that the drone is damaged due to the collision between the moving chassis 1 and branches, thus achieving the protective effect of the drone and bringing convenience to forest fire extinguishing.

[0033] The support columns 13 are made of polyethylene material, and the number of support columns 13 is three. By setting the support columns 13, when the fire extinguishing drone lands, the support columns 13 can support the falling chassis 1, avoiding the problem that the drone is damaged when it directly contacts the ground during landing, thus improving the safety of the drone during landing.

[0034] The anti-slip sleeve 14 is made of rubber material, and the front shape of the anti-slip sleeve 14 is conical. By setting the anti-slip sleeve 14, when the drone lands, the anti-slip sleeve 14 can greatly increase the friction between the support column 13 and the ground, avoiding the problem that the support column 13 collides with the ground when it quickly lands on the ground, resulting in violent vibration of the drone, thus improving the stability of the drone during landing.

[0035] The closing cover 15 is located directly above the water tank 4, and the closing cover 15 is adapted to the water tank 4. By setting the closing cover 15, when adding fire extinguishing agent, rotate the closing cover 15, so that the closing cover 15 can be detached from the top of the water tank 4, thus opening the water tank 4, which brings convenience to the addition of fire extinguishing agent and improves the diversity of fire extinguishing materials of the fire extinguishing drone.

[0036] The auxiliary mechanism 16 includes a water connection pipe 161. The water connection pipe 161 is fixedly sleeved on the bottom of the water tank 4, and a valve 162 is installed on the outside of the water connection pipe 161. By setting the auxiliary mechanism 16, when adding fire extinguishing water flow, fix the external water injection pipe in the water connection pipe 161, so that the external water source can be injected into the water tank 4 through the water connection pipe 161, thus achieving the connection effect of the external water source for fire extinguishing water flow and improving the convenience of adding water flow to the fire extinguishing drone.

[0037] The working principle of a fire - fighting unmanned aerial vehicle provided by the utility model is as follows:

[0038] First step: When the unmanned aerial vehicle is used for sprinkler fire - fighting, open the sprinkler nozzle 7 and start the rotating motor 2. The rotating motor 2 drives the three sprinkler nozzles 7 to flip through the adjusting column 3, achieving the adjustment effect of the sprinkling angles of the three sprinkler nozzles 7. This avoids the problem that the sprinkling angle adjustment requires moving the unmanned aerial vehicle, which makes the fire - fighting work more complex, thus improving the practicability of the fire - fighting unmanned aerial vehicle. When sprinkler fire - fighting, start the water pump 5, so that the water pump 5 sucks the water flow inside the water tank 4 and then transports it to the inside of the sprinkler nozzle 7 through the corrugated pipe 6, increasing the flow velocity of the water flow, that is, increasing the spraying lift of the water flow, and thus increasing the spraying distance of the water flow. During night fire - fighting operations, start the searchlight 8, so that the searchlight 8 illuminates the area below the chassis 1, achieving the marking effect of the position of the chassis 1, and thus bringing convenience to the night control of the unmanned aerial vehicle. When the unmanned aerial vehicle is used for sprinkler fire - fighting, start the rotating motor 112, so that the rotating motor 112 drives the rotor 113 to rotate rapidly, and the four rotors 113 drive the water tank 4 to rise through the chassis 1, achieving the lifting and conveying effect of the water flow;

[0039] Second step: When carrying out forest garden fire - fighting operations, the protective frame 12 limits the position of the chassis 1, avoiding the problem that the chassis 1 collides with tree branches when moving, which may cause damage to the unmanned aerial vehicle, thus achieving the protection effect of the unmanned aerial vehicle and bringing convenience to forest garden fire - fighting. When the fire - fighting unmanned aerial vehicle lands, the support column 13 supports the falling chassis 1, avoiding the problem that the unmanned aerial vehicle is damaged when it directly contacts the ground during landing, thus improving the safety of the unmanned aerial vehicle during landing. When the unmanned aerial vehicle lands, the anti - slip sleeve 14 greatly increases the friction between the support column 13 and the ground, avoiding the problem that the support column 13 impacts the ground when it quickly lands on the ground, causing the unmanned aerial vehicle to vibrate violently, thus improving the stability of the unmanned aerial vehicle during landing.

[0040] Compared with the related technology, a fire - fighting unmanned aerial vehicle provided by the utility model has the following beneficial effects:

[0041] By setting the sprinkler nozzle 7, when the unmanned aerial vehicle is used for sprinkler fire - fighting, open the sprinkler nozzle 7 and start the rotating motor 2. The rotating motor 2 drives the three sprinkler nozzles 7 to flip through the adjusting column 3, achieving the adjustment effect of the sprinkling angles of the three sprinkler nozzles 7. This avoids the problem that the sprinkling angle adjustment requires moving the unmanned aerial vehicle, which makes the fire - fighting work more complex, thus improving the practicability of the fire - fighting unmanned aerial vehicle.
