Description

Technical Field

[0001] This application relates to the field of tethered drone technology, and in particular to a tethered drone for firefighting. Background Technology

[0002] When a fire breaks out in a high-rise building, the vertical distance that people need to evacuate is relatively long. Ordinary fire trucks have limited height, making it difficult to effectively extinguish fires from the outside when they occur in high-rise buildings exceeding 100 meters in height. In such cases, firefighters can use tethered drones to carry water hoses and fire nozzles to extinguish fires in high-rise buildings. This method is not limited by ground traffic conditions or internal building passages.

[0003] Existing tethered drones include a fuselage, four propellers mounted on the fuselage, a power supply mounted on the fuselage, and a control unit mounted on the fuselage. The four propellers are located at the four corners of the fuselage. The power supply is used to drive the propellers to rotate. The control unit is electrically connected to the power supply and the propellers. When a worker uses the tethered drone for work, the worker turns on the power supply and then controls the tethered drone through a remote control. At this time, the control unit controls the propellers to rotate, and the tethered drone begins to fly.

[0004] The water hoses and nozzles carried by the aforementioned tethered drones during firefighting operations are relatively small and cannot meet the needs of long-term, large-scale firefighting, thus requiring improvement. Utility Model Content

[0005] In order to increase the specifications of water hoses and nozzles that tethered drones can carry during firefighting operations, thereby meeting the needs of long-term and large-scale firefighting, this application provides a tethered drone for firefighting.

[0006] This application provides a tethered drone for firefighting, which adopts the following technical solution:

[0007] A tethered unmanned aerial vehicle (UAV) for firefighting includes a fuselage, a flight mechanism mounted on the fuselage, a control component mounted on the inner wall of the fuselage, and an extension block fixed to the lower part of the fuselage. The control component is electrically connected to the flight mechanism, and the side wall of the extension block has a mounting groove for mounting a water gun.

[0008] By adopting the above technical solution, when staff use tethered drones, they can install water guns onto the drones through the mounting slots. Then, the control unit controls the flight mechanism to fly the drones to the fire-fighting location. At this point, the drones begin firefighting operations using the water guns. When different sizes of water guns are needed, staff can install them onto the inner wall of the mounting slots. This design increases the range of hoses and water guns that tethered drones can carry during firefighting operations, thus meeting the needs of long-term, large-scale firefighting.

[0009] Optionally, the sidewall of the expansion block is further provided with several snap-fit ​​slots, which are close to the mounting slot.

[0010] By adopting the above technical solution, when staff use tethered drones for firefighting, they can install different extended function modules on the tethered drones through the snap-fit ​​slots. This setting further increases the working range of the tethered drones, thereby making it easier for staff to use them for firefighting.

[0011] Optionally, the flight mechanism includes a support rod fixed to the side wall of the fuselage, a drive component installed at one end of the support rod away from the fuselage, and a rotor installed above the drive component. The drive component is electrically connected to the control component and is used to drive the rotor to rotate.

[0012] By adopting the above technical solution, when staff use the tethered drone, the control unit controls the drive unit to start, and the drive unit drives the rotor to rotate. Under the lift provided by the rotor, the drone body moves away from the ground. This setting improves the stability of the tethered drone during flight.

[0013] Optionally, the flight mechanism is provided in six groups, which are arranged along the circumference of the aircraft body and are evenly spaced.

[0014] By adopting the above technical solution, the arrangement of six flight mechanisms makes the lift distribution of the tethered drone more uniform during flight, thereby reducing the vibration of the tethered drone during flight, thus improving the stability of the tethered drone during flight, and further increasing the accuracy of the tethered drone's control over the water gun.

[0015] Optionally, a sensor is fixed on the top of the machine body, and the sensor is electrically connected to the control unit.

[0016] By adopting the above technical solution, the sensor settings make it easier for staff to obtain a wider detection range, thereby reducing the possibility of external interference when staff use tethered drones and obtaining an unobstructed field of vision.

[0017] Optionally, landing gear is fixed on both sides of the fuselage, and friction elements are fixed on the side walls of the landing gear.

[0018] By adopting the above technical solution, the landing gear and friction components make the landing process of tethered drones more stable and reduce the possibility of damage to tethered drones during recovery.

[0019] Optionally, a water jet gun is fixed to the inner wall of the mounting groove, and an extension hose is installed on the lower side of the extension block, with the water jet gun communicating with the extension hose.

[0020] By adopting the above technical solution, the water jet gun and the extension hose are designed so that the staff do not need to carry the water hose during the operation of the tethered drone. Instead, the required water flow can be pumped directly from the ground to the inside of the water jet gun, thereby reducing the load on the tethered drone.

[0021] Optionally, an extension cable is installed on the lower side of the body, and the extension cable is electrically connected to the control unit.

[0022] By adopting the above technical solution, the extension of the cable allows staff to power the tethered drone from the ground, thereby improving the drone's endurance and, consequently, its working range.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When staff use tethered drones, they install water guns onto the drones via the mounting slot. The control unit then controls the flight mechanism, which propels the drone into flight. The tethered drone then controls the water guns to extinguish fires. When extinguishing fires in different environments, staff install water guns of different specifications in the mounting slot. This feature increases the range of hoses and water guns that tethered drones can carry during firefighting operations, thus meeting the needs of long-term, large-scale firefighting.

[0025] 2. The evenly spaced six flight mechanisms enhance the stability of the tethered drone during flight and reduce the tendency of the drone to rotate, thereby improving the accuracy of the drone when using water cannons.

[0026] 3. The installation of extended water hoses and extension cables improves the endurance of tethered drones, thereby increasing their working range and ultimately improving their working efficiency. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a tethered drone for firefighting.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2 A tethered unmanned aerial vehicle (UAV) for firefighting includes a body 1, a flight mechanism 2 mounted on top of the body 1, a control component 3 disposed on the upper side of the body 1, and an extension block 4 fixed to the lower side of the body 1. In this embodiment, the body 1 includes a lower metal plate, an upper metal plate fixed to the upper side of the lower metal plate by a support column, and an end cap fixed to the upper side of the upper metal plate. The control component 3 is preferably a flight control board, and the control component 3 is fixed to the upper side of the upper metal plate by bolts. The sidewalls of the extension block 4 are respectively fixed with mounting grooves 5 and several snap-fit ​​grooves 6. In this embodiment, two snap-fit ​​grooves 6 are preferably located above the mounting grooves 5, and the diameter of the snap-fit ​​grooves 6 is smaller than the diameter of the mounting grooves 5. The mounting grooves 5 are used to install water guns, and the snap-fit ​​grooves 6 are used to snap-fit ​​functional expansion modules.

[0036] Reference Figure 1 and Figure 2 A sensor 7 is fixed to the upper side of the upper metal plate by bolts. The sensor 7 is electrically connected to the control component 3. Two landing gears 8 are fixed to the lower side of the lower metal plate by bolts. The two landing gears 8 are located on both sides of the lower metal plate. The landing gears 8 are I-shaped. Friction components 9 are glued to both ends of the landing gears 8. The friction components 9 are located on the landing gears 8 away from the fuselage 1. The side wall of the friction component 9 can abut against the ground.

[0037] Reference Figure 1 and Figure 3The flight mechanism 2 includes a support rod 21 that is snapped and fixed between the upper metal plate and the lower metal plate, a drive component 22 that is fixed to the end of the support rod 21 away from the body 1 by a connector, and a rotor 23 installed on the upper side of the drive component 22. In this embodiment, the drive component 22 is preferably a motor, the rotation shaft of the drive component 22 is interference-fitted with the middle part of the rotor 23, the drive component 22 is electrically connected to the control component 3, and the flight mechanism 2 is preferably six groups, with the six groups of flight mechanisms 2 evenly spaced.

[0038] According to Embodiment 1 of this application, the implementation principle of a tethered drone for firefighting is as follows: When workers use the tethered drone to extinguish fires, they install water guns onto the inner wall of the mounting slot 5, and then install the functional expansion module onto the inner wall of the snap-fit ​​slot 6. Subsequently, workers control the drive unit 22 through the control unit 3, which drives the rotor 23 to rotate. Under the lift of the six sets of rotors 23, the tethered drone takes off. At this time, the tethered drone controls the water gun to work on the area to be extinguished. In different firefighting environments, workers install water guns of different specifications on the inner wall of the mounting slot 5. This setting increases the specifications of water hoses and water guns that the tethered drone can carry when carrying out firefighting operations, thereby meeting the needs of long-term and large-scale firefighting.

[0039] Example 2

[0040] Example 2 differs from Example 1 in that: (Refer to...) Figure 4 The inner wall of the mounting slot 5 is fitted with a water jet gun 10. An extension water hose 11 is fixed to the lower side of the extension block 4. The extension water hose 11 is connected to the water jet gun 10. An extension cable 12 is fixed to the lower side of the body 1. The extension cable 12 is electrically connected to the control unit 3. The staff can provide the tethered drone with continued operation through the extension water hose 11 and the extension cable 12.

[0041] According to Embodiment 2 of this application, the implementation principle of a tethered drone for firefighting is as follows: When staff use the tethered drone for firefighting, the staff directly control the tethered drone to fly to a high place, and then the staff directly supply water to the spray gun 10 through the extended water hose 11. During the process, the staff directly supplies power to the tethered drone through the extended cable 12. This setting increases the working range of the tethered drone, thereby improving the firefighting efficiency of the tethered drone.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
