Description

Technical Field

[0001] The present invention relates to the technical field of rescue drones, and specifically to a vertical take-off and landing disc-shaped drone. Background Art

[0002] A drone is short for an unmanned aerial vehicle, which is an unpiloted aircraft using radio remote control equipment and self-contained program control devices, including unmanned helicopters, fixed-wing aircraft, multi-rotor aircraft, unmanned airships, and unmanned parafoil aircraft. In recent years, with the development of technology, drone technology has gradually been introduced into the field of fire rescue. In particular, vertical take-off and landing rescue drones have gradually become an effective auxiliary tool for fire rescue due to their advantages such as flexible control and rapid response. Such drones are mainly applied to complex environments such as high-rise building fires and forest fires, and can quickly reach the disaster site to carry out tasks such as monitoring and extinguishing fires. However, although drones have made certain developments in the rescue field, the current technology still has many limitations and is difficult to fully meet the actual needs in complex fire situations.

[0003] The fire extinguishing method of drones in the prior art usually relies on a single dry powder or water mist fire extinguishing device for fire extinguishing. This method has poor adaptability to different fire types. For liquid fires and solid fires, the requirements for fire extinguishing agents are different, and it is difficult for a single type of fire extinguishing device to quickly switch and adapt. In addition, it is difficult to effectively prevent re-ignition after fire extinguishing, which easily leads to repeated fire situations and has a great impact on the fire extinguishing efficiency. Existing fire-fighting drones lack the flexible fire extinguishing ability for multiple fire scenarios.

[0004] In terms of the structural design of drones, the current mainstream vertical take-off and landing drones mostly adopt a single motor and single propeller design. This design is prone to tilting or even crashing of the fuselage due to wind or load changes during take-off and landing, especially in high-rise buildings and strong airflow environments. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vertical take-off and landing disc-shaped drone, which solves the problem that the fire extinguishing method of drones in the prior art usually relies on a single dry powder or water mist fire extinguishing device for fire extinguishing and has poor adaptability to different fire types.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A vertical take-off and landing disc-shaped unmanned aerial vehicle, comprising: a drone housing, on which a bracket is fixed; a drive assembly, which is arranged on the bracket and is used to drive the drone to take off; an auxiliary assembly, which is arranged inside the drone housing and is used to assist the drive assembly; a fire extinguishing assembly, which is arranged inside the drone housing and is used to extinguish fires at the fire scene. The fire extinguishing assembly includes a launch platform, the outer wall of the launch platform is fixed inside the drone housing, and multiple dry powder fire extinguishing bombs and multiple foam fire extinguishing bombs are arranged inside the launch platform; a monitoring assembly, which is arranged inside the drone housing and is used to monitor the situation of the fire; a water spraying assembly, which is arranged inside the drone housing and is used to spray water again on the fire extinguishing area.

[0007] Preferably, the water spraying assembly includes a water tank, the outer wall of the water tank is fixed inside the drone housing, the outer wall of the water tank is communicated with the input end of a water pump, the output end of the water pump is fixed with a delivery pipe, and the end of the delivery pipe is fixed with a nozzle.

[0008] Preferably, the drive assembly includes two motors 1 that are symmetrically arranged up and down. The outer wall of the motor 1 is fixed on the bracket, the drive end of the motor 1 is fixed with a rotating rod, and the end of the rotating rod is fixed with a spiral blade.

[0009] Preferably, the auxiliary assembly includes a fixed cylinder, and the outer wall of the fixed cylinder is fixed inside the drone housing.

[0010] Preferably, a motor 2 is fixed inside the fixed cylinder, and the drive end of the motor 2 is fixed with a propeller.

[0011] Preferably, the monitoring assembly includes a rotating base, a rotating shaft is fixed inside the rotating base, a telescopic rod is fixed at the top of the rotating shaft, a connecting seat is fixed at the drive end of the telescopic rod, and a camera group is fixed inside the connecting seat.

[0012] Preferably, a lithium battery is fixed inside the drone housing, and a fire source analysis module is fixed inside the drone housing. The fire source analysis module is a multi-functional fire detection system, including a multi-spectral sensor, a data processing unit, and a wireless communication module. The multi-spectral sensor is used to collect data in the infrared, ultraviolet, and visible light bands at the fire scene. The data processing unit is used to analyze the fire source position, flame temperature, and type of combustible substances. The wireless communication module is used to transmit the analysis results to the ground control center or other components of the drone in real time.

[0013] Preferably, the lower surface of the drone housing is fixed with support feet by bolts, and support feet of different shapes can be replaced according to the actual situation.

[0014] The present invention provides a vertical take-off and landing disc-shaped drone, which has the following beneficial effects:

[0015] 1. Through the cooperation between the fire extinguishing component and the water spraying component, the dry powder fire extinguishing bomb and the foam fire extinguishing bomb play the role of improving the fire extinguishing efficiency, solving the problems of low efficiency and slow response of traditional fire extinguishing methods in dealing with multiple types of fires. By selectively dropping different fire extinguishing bombs according to the type of fire, the spread of the fire can be quickly suppressed. At the same time, the water spraying component plays a role in cooling and preventing re-ignition after the fire is extinguished.

[0016] 2. Through the cooperation between the driving component and the auxiliary component, the double motors running independently up and down are connected by a bracket, and one driving spiral rotates forward and the other rotates backward, so that the drone maintains balance during vertical take-off and landing, solving the problem that traditional drones are prone to tilt or crash due to the instability of a single spiral during take-off and landing, and improving the operation stability and reliability of the drone.

[0017] 3. Through the cooperation between the fire source analysis module and the monitoring component, the fire situation is quickly analyzed, reducing blind exploration and improving the fire extinguishing efficiency, solving the problem of delaying the fire extinguishing time due to information asymmetry in the traditional rescue process. The fire source analysis module collects the data of the fire scene through a multi-spectral sensor and constructs a fire source model in real time. Combining with the multi-angle pictures provided by the monitoring component, it can accurately locate and monitor the fire source and judge the development trend of the fire.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to the attached Figure 1 - attached Figure 5 , the embodiments of the present invention provide a vertically lifting disc-shaped UAV, including: a UAV housing 1, on which a bracket 2 is fixed; a driving assembly 3, which is arranged on the bracket 2 and is used to drive the UAV to take off; an auxiliary assembly 4, which is arranged inside the UAV housing 1 and is used to assist the driving assembly 3; a fire extinguishing assembly 5, which is arranged inside the UAV housing 1 and is used to extinguish fires at the fire scene. The fire extinguishing assembly 5 includes a launch pad 501, the outer wall of the launch pad 501 is fixed inside the UAV housing 1, and multiple dry powder fire extinguishing bombs 502 are arranged inside the launch pad 501, and multiple foam fire extinguishing bombs 503 are arranged inside the launch pad 501; a monitoring assembly 6, which is arranged inside the UAV housing 1 and is used to monitor the situation of the fire; a water spraying assembly 7, which is arranged inside the UAV housing 1 and is used to spray water again on the fire extinguishing area. The water spraying assembly 7 includes a water tank 701, the outer wall of the water tank 701 is fixed inside the UAV housing 1, the outer wall of the water tank 701 is communicated with the input end of a water pump 702, the output end of the water pump 702 is fixed with a delivery pipe 703, and the end of the delivery pipe 703 is fixed with a nozzle 704.

[0027] Specifically, through the collaborative work of the fire extinguishing component 5 and the water spraying component 7, the functions of efficiently extinguishing fires and subsequent treatment are achieved. The launch pad 501 built into the fire extinguishing component 5 can carry multiple groups of dry powder fire extinguishing bombs 502 and foam fire extinguishing bombs 503, and selectively launch dry powder fire extinguishing bombs 502 according to different types of fire sources to quickly isolate oxygen and suppress the fire, or launch foam fire extinguishing bombs 503 to cover the combustion area to prevent re-ignition, further improving the applicability and pertinence of fire extinguishing. The water spraying component 7 stores water liquid in the water tank 701, pressurizes the water liquid by using the water pump 702 and transports it to the nozzle 704 through the delivery pipe 703 for water spraying operation, and conducts secondary cooling and temperature reduction treatment on the area after fire extinguishing, thereby effectively preventing the re-burning of the fire source and enhancing the thoroughness of fire extinguishing. The present invention has the ability to adapt to multiple types of fire scenarios, and at the same time simplifies the operation process through modular design, not only improving the fire extinguishing efficiency, but also reducing the dependence on manpower in traditional fire fighting methods, and showing strong flexibility and stability in complex environments.

[0028] Please refer to the attached Figure 1 - attached Figure 3 , the driving component 3 includes two symmetrically arranged motors one 301 up and down. The outer wall of the motor one 301 is fixed on the bracket 2, the driving end of the motor one 301 is fixed with a rotating rod 302, and the end of the rotating rod 302 is fixed with a spiral blade 303. The auxiliary component 4 includes a fixed cylinder 401. The outer wall of the fixed cylinder 401 is fixed inside the UAV housing 1, and a motor two 402 is fixed inside the fixed cylinder 401. The driving end of the motor two 402 is fixed with a propeller 403.

[0029] Specifically, the motor one 301 drives the rotating rod 302 to rotate at a high speed and generates a strong thrust through the spiral blade 303 to ensure that the UAV can achieve stable lifting and lowering under different load conditions. The fixed cylinder 401 in the auxiliary component 4 plays a role in structural support, and the internal motor two 402 and the propeller 403 cooperate to provide additional power output for enhancing flight stability and attitude control ability. This dual-power design effectively solves the problem of flight instability of traditional single-power systems under complex airflow conditions, and at the same time greatly improves the load capacity and adaptability of the UAV.

[0030] Please refer to the attached Figure 2 - attached Figure 6, the monitoring component 6 includes a rotating base 601. Inside the rotating base 601, a rotating shaft 602 is fixed. At the top of the rotating shaft 602, a telescopic rod 603 is fixed. At the driving end of the telescopic rod 603, a connecting seat 604 is fixed. Inside the connecting seat 604, a camera group 605 is fixed. The camera group 605 is used to monitor the specific situation of the fire in real time. Inside the drone housing 1, a lithium battery 9 is fixed. Inside the drone housing 1, a fire source analysis module 10 is fixed. The fire source analysis module 10 is a multi-functional fire detection system, including a multi-spectral sensor, a data processing unit, and a wireless communication module. The multi-spectral sensor is used to collect data in the infrared, ultraviolet, and visible light bands at the fire scene. The data processing unit is used to analyze the fire source location, flame temperature, and type of combustible substances. The wireless communication module is used to transmit the analysis results to the ground control center or other components of the drone in real time. The lower surface of the drone housing 1 is fixed with support feet 8 by bolts, and different-shaped support feet 8 can be replaced according to actual situations.

[0031] Specifically, the rotating base 601 drives the rotating shaft 602 to rotate omnidirectionally, enabling the camera group 605 to cover a wider monitoring range. The rotating shaft 602 and the telescopic rod 603 cooperate to further extend the monitoring perspective height. The connecting seat 604 provides a stable installation foundation for the camera group 605, ensuring clear images and no vibration interference during the flight of the drone. The camera group 605 can collect picture data of the fire scene from multiple angles, providing detailed information for fire monitoring and subsequent analysis. At the same time, combined with the AI intelligent function of automatically generating photos and short videos, it can automatically capture key pictures and generate short videos according to the on-site fire situation, greatly improving the automation and accuracy of fire scene data collection, facilitating subsequent processing and decision-making support. The fire source analysis module 10 obtains accurate data in the infrared, ultraviolet, and visible light bands through the multi-spectral sensor, analyzes the type, location, and flame temperature of the fire source with the help of the data processing unit, and simultaneously sends the analysis results to the ground command center in real time through the wireless communication module for quick decision-making.

[0032] Working principle: First, two motors 301 that are symmetrically arranged up and down drive the rotating rod 302 to rotate. The rotating rod 302 realizes a rotation mode of one forward rotation and one reverse rotation through the driving spiral blades 303, so as to ensure the balance and stability of the drone during vertical takeoff and landing. The motor 402 in the fixed cylinder 401 drives the propeller 403 to further enhance the flight ability and attitude stability of the drone. When the drone enters the fire scene, the rotating base 601 drives the telescopic rod 603 to extend through the rotation of the rotating shaft 602. The connecting seat 604 on the telescopic rod 603 further fixes the camera group 605 to conduct all-round real-time monitoring of the fire area. The data collected is processed by the multi-spectral sensor, data processing unit, and wireless communication module in the fire source analysis module 10 working together. The multi-spectral sensor collects data in the infrared, ultraviolet, and visible light bands of the fire scene. The data processing unit analyzes the fire source position, flame temperature, and type of combustible substances and generates a fire situation model. The wireless communication module transmits the analysis results to the ground control center and the drone control system. Then, dry powder fire extinguishing bombs 502 or foam fire extinguishing bombs 503 are launched through the launch pad 501. The dry powder fire extinguishing bombs 502 are used to cut off oxygen and extinguish the flame, and the foam fire extinguishing bombs 503 are used to cover the fire source to prevent re-ignition. When the fire extinguishing bombs are launched, the water liquid is transported through the delivery pipe 703 to the nozzle 704 by the water pump 702 in the water tank 701, and the nozzle 704 conducts water spraying and cooling treatment on the target area. Finally, the support feet 8 can adjust their shapes according to the on-site terrain conditions to stabilize the landing attitude of the drone, and the operation of all components is powered by the lithium battery 9.
