Description

Technical Field

[0001] This invention relates to the field of rescue equipment technology, and in particular to a rapid rescue drone for high-rise buildings. Background Technology

[0002] The specific rescue solutions and limitations of existing technologies for high-rise buildings in the event of emergencies such as fires and earthquakes are as follows:

[0003] (1) Ladder fire truck: It adopts a hydraulic telescopic ladder with a maximum working height of about 100 meters. The disadvantage is that it is limited by the width of the street and the height of the building, and cannot cover super high-rise buildings (≥100 meters); the deployment time is long (≥10 minutes) and the emergency rescue efficiency is low.

[0004] (2) Descent device and escape slide: guide trapped personnel to descend on their own via rope or slide; the disadvantage is that the trapped personnel need to have the ability to operate it, and it is not suitable for children, the elderly and the injured; the slide is easily damaged by high temperature or smoke.

[0005] (3) Traditional rescue helicopters: Due to urban airspace control and obstacle restrictions, they usually operate at an altitude of ≥100 meters, require professional pilots to operate, and cannot directly reach the rescue window, so they can only carry out rescues on the roof.

[0006] (4) Traditional rescue drones: Multi-rotor drones carry light rescue equipment, such as ropes and first aid kits; the disadvantages are low payload capacity (≤50kg), which cannot carry multiple people; short flight time (≤20 minutes); poor wind resistance (≤6 levels), and complex environments such as smoke and strong winds can easily cause the drone to lose control or fail to navigate. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a rapid rescue drone for high-rise buildings, capable of docking with the exterior wall of a target window to achieve rapid and automated rescue in super high-rise buildings.

[0008] In order to achieve the objective of this invention, the following solution is proposed:

[0009] A rapid rescue drone for high-rise buildings includes a manned cabin, a multi-rotor power system located on the top of the manned cabin, and front and rear covers located at both ends of the manned cabin.

[0010] The multi-rotor power system includes multiple sets of symmetrically arranged rotors, each set of rotors including a brushless motor, a speed controller and a propeller connected in sequence;

[0011] The manned cabin integrates an intelligent navigation and control system and an intelligent power distribution system. The intelligent navigation and control system includes a lidar module, an infrared camera module, and an ultrasonic obstacle avoidance module, which are used to build a 3D environmental map in real time and accurately identify building windows and obstacles. The intelligent power distribution system includes a central control module and multiple load sensors installed at the bottom of the manned cabin. The load sensors are used to monitor the load distribution of the manned cabin in real time and send the load information to the central control module. The central control module is used to dynamically adjust the power output of each set of rotors according to the load information to keep the UAV balanced.

[0012] The bottom of the manned cabin is equipped with multiple inflatable cushioning balls;

[0013] The bottom of the front cover is rotatably connected to the manned cabin, and the top is equipped with an inflatable buffer strip. When the front cover automatically flips down under the action of its power source, it is used to dock with the building's exterior wall of the target window.

[0014] Furthermore, the front cover includes a main cover, a telescopic bridge, and a sliding cover. The main cover is rotatably connected to the manned cabin. The telescopic bridge is connected to the main cover on both sides via a first slide rail. An inflatable buffer strip is located at the top of the telescopic bridge. The sliding cover is connected to the telescopic bridge on both sides via a second slide rail. When the front cover automatically flips down under the action of its power source, the first slide rail is used to extend the telescopic bridge until the inflatable buffer strip contacts the building's exterior wall of the target window. The second slide rail is used to extend the sliding cover until the sliding cover covers the inflatable buffer strip.

[0015] Furthermore, a flexible sealing strip is provided at the top of the sliding cover.

[0016] Furthermore, the front cover also includes two protective nets located on both sides of the front cover. The protective nets are divided into a flattened section and a folded section. The flattened section is located on the main cover, and the folded section is located on the telescopic bridge. When the telescopic bridge extends, the folded section of the protective net unfolds accordingly.

[0017] Furthermore, the manned cabin is equipped with multiple booms.

[0018] Furthermore, the top of the manned cabin is equipped with multiple emergency parachute packs.

[0019] Furthermore, the manned cabin is designed in a cage shape, with both the front and rear covers made of mesh.

[0020] Furthermore, the multi-rotor power system also includes a redundancy design module. When any motor in each rotor group fails, the redundancy design module is used to automatically adjust the power distribution of the remaining motors to keep the UAV balanced.

[0021] Furthermore, a carbon fiber frame is installed on the outside of the inflatable cushioning ball.

[0022] The beneficial effects of this invention are: it can break through the height limitations of existing rescue equipment and realize rapid rescue of super high-rise buildings; it can automatically connect to the building exterior wall of the target window and provide an automated rescue solution that does not require operation by trapped personnel; it can improve the payload capacity and endurance of UAVs; and it can enhance navigation stability and anti-interference capabilities in complex environments.

[0032] like Figure 1 As shown, this embodiment provides a high-rise building rapid rescue lifting drone, including a manned cabin 1, a multi-rotor power system 4 located on the top of the manned cabin 1, and a front cover 2 and a rear cover 3 located at both ends of the manned cabin 1, both of which are designed as mesh structures.

[0033] Specifically, the manned cabin 1 is designed as a cylindrical or rectangular cage with a high-strength carbon fiber composite frame. A battery pack is installed on the lower side of the manned cabin 1, which supports 40 minutes of continuous operation and 30 minutes of fast charging. The manned cabin 1 can accommodate 8-10 people and has multiple booms inside. The booms are designed to help people hold onto the equipment to maintain their position.

[0034] Specifically, the bottom of the manned cabin 1 is equipped with eight inflatable cushioning balls 11, which are filled with high-pressure gas, such as nitrogen. The inflatable cushioning balls 11 are made of high-strength rubber or polyurethane materials, which have good elasticity and wear resistance. The inflatable cushioning balls 11 are pre-inflated before the drone takes off, maintaining a certain air pressure and elasticity. When the drone hits the ground, they absorb the impact energy by compressing the gas, which is used to ensure that the drone can effectively absorb the impact force when it hits the ground, protecting the personnel in the manned cabin 1. After the impact, the inflatable cushioning balls 11 automatically return to their original shape by relying on the internal air pressure, ready for the next use.

[0035] Preferably, a carbon fiber frame is provided on the outside of the inflatable cushioning ball 11 to prevent the inflatable cushioning ball 11 from deforming excessively when it touches the ground.

[0036] The inflatable cushioning ball 11 provided in this embodiment has the following advantages:

[0037] ① No need for temporary inflation: The pre-inflated design avoids the delay of inflation upon ground contact, resulting in a faster response time;

[0038] ②Simple structure: No additional high-pressure gas cylinders and filling devices are required, reducing system complexity;

[0039] ③ High reliability: The inflatable cushioning ball 11 functions directly upon contact with the ground, without relying on an external triggering mechanism.

[0040] Specifically, the top of the manned cabin 1 is equipped with multiple emergency parachute packs 5. The emergency parachute packs 5 are triggered by a barometric pressure sensor and automatically eject when the drone stalls or drops in altitude.

[0041] Specifically, such as Figure 2 As shown, the multi-rotor power system 4 includes six symmetrically arranged rotors. Each rotor includes an independent high-power brushless motor, a speed controller, and a carbon fiber propeller. The output shaft of the brushless motor is connected to the speed controller, which is connected to the propeller. The function of the speed controller is to ensure precise control of power output. The thrust of a single motor is ≥220kg, and the total load is ≥1320kg. The total load = 900kg (weight of 10 people + safety factor) + 300kg (weight of the drone) + 100kg (extra load) = 1300kg.

[0042] More specifically, the multi-rotor power system 4 also includes a redundancy design module. The redundancy design module is used to monitor the working status of all motors in each group of rotors in real time. Once a fault is detected in a motor, common faults include motor stoppage, overheating, or abnormal current. The redundancy design module will automatically adjust the power distribution of the remaining motors to keep the UAV balanced and stable in flight.

[0043] Specifically, the manned cabin 1 integrates an intelligent navigation and control system. Communication uses military-grade encrypted frequency bands to ensure stable signals even in smoke and electromagnetic interference environments. The intelligent navigation and control system includes a lidar module, an infrared camera module, and an ultrasonic obstacle avoidance module, used to build real-time 3D environmental maps and accurately identify building windows and obstacles, as detailed below:

[0044] In the lidar module, lidar obtains a detailed three-dimensional map of the surrounding environment by emitting a laser beam and measuring the time it takes for it to reflect back. It features high precision, wide range, and real-time performance.

[0045] In the infrared camera module, the infrared camera can capture images of the environment, identify and track specific objects through image processing algorithms, and enhance environmental perception capabilities;

[0046] Ultrasonic obstacle avoidance modules detect the distance to obstacles by emitting ultrasonic waves and measuring the time it takes for the reflected waves to travel, enabling rapid response. They are widely used in obstacle avoidance functions in fields such as robots and unmanned vehicles.

[0047] The lidar module, infrared camera module, and ultrasonic obstacle avoidance module work together in the intelligent navigation and control system. The lidar module provides high-precision environmental modeling, the infrared camera module enhances visual perception capabilities, and the ultrasonic obstacle avoidance module effectively avoids obstacles at close range, enabling the intelligent navigation and control system to operate safely and efficiently in complex and dynamic environments. After the rescue is completed, the intelligent navigation and control system can avoid fire sources and obstacles, automatically plan the optimal descent path, and land vertically in a safe area.

[0048] Specifically, the manned cabin 1 integrates an intelligent power distribution system, which includes a central control module and multiple load sensors installed at the bottom of the manned cabin 1. The load sensors are used to monitor the load distribution of the manned cabin 1 in real time and send the load information to the central control module. The central control module is used to receive the load information sent by the load sensors and dynamically adjust the power output of each set of rotors according to the load information to ensure that the UAV can maintain balance when the load distribution is uneven.

[0049] Specifically, such as Figure 1 As shown, the bottom end of the front cover 2 is rotatably connected to the manned cabin 1. The top of the front cover 2 is provided with an inflatable buffer strip 24. When the front cover 2 automatically flips down under the action of its power source, it is used to dock with the building exterior wall of the target window. The function of the inflatable buffer strip 24 is to provide a buffer when docking with the building exterior wall. Similar to the inflatable buffer ball 11, in order to prevent the inflatable buffer strip 24 from being excessively deformed when in contact with the building exterior wall, a carbon fiber frame is set on the outside of the inflatable buffer strip 24.

[0050] There are many ways to implement the front cover 2; this embodiment adopts the following method: (e.g.) Figure 3 ,Figure 4 As shown, the front cover 2 includes a main cover 21, a telescopic bridge 22, a sliding cover 23, and two protective nets 25. The main cover 21 is rotatably connected to the manned cabin 1. The telescopic bridge 22 is connected to the main cover 21 on both sides via a first slide rail, which controls the extension or retraction of the telescopic bridge 22. An inflatable buffer strip 24 is located at the top of the telescopic bridge 22. The sliding cover 23 is connected to the telescopic bridge 22 on both sides via a second slide rail, which also controls the extension or retraction of the sliding cover 23. The two protective nets 25 are located on both sides of the front cover 2. The protective nets 25 can be made of nylon mesh and are divided into a flattened section and a folded section. The flattened section is located on the main cover 21, and the folded section is located on the telescopic bridge 22. When the telescopic bridge 22 extends, the folded section of the protective net 25 unfolds accordingly, improving safety; when the telescopic bridge 22 retracts, the folded section of the protective net 25 folds in conjunction.

[0051] The front cover 2 is used as follows: the front cover 2 automatically flips down under the action of its power source, as shown in the figure. Figure 3 As shown; the first slide rail extends the telescopic bridge 22 until the inflatable buffer strip 24 contacts the building's exterior wall of the target window. During this process, the protective net 25 is in the deployed state, as shown. Figure 7 As shown; the second slide rail extends the sliding cover 23 until it covers the inflatable buffer strip 24, and the flexible sealing strip at the end of the sliding cover 23 contacts the building's exterior wall. The function of the sliding cover 23 is to prevent personnel from stepping on the inflatable buffer strip 24 when climbing the telescopic bridge 22, as shown. Figure 8 As shown.

[0052] The front cover 2 provided in this embodiment has the following advantages:

[0053] ①Structural optimization: The sliding cover 23 and the inflatable buffer strip 24 are designed in layers to avoid interference with the buffer function when stepped on;

[0054] ② Joint protection: The protective net 25 and the telescopic bridge 22 deploy simultaneously to improve the safety of rescue operations;

[0055] ③ Fully automated: No operation required by trapped personnel, suitable for children, the elderly and the injured.

[0056] One point to note here is that, Figure 3 , Figure 4 The diagram shown is of the front cover 2 and does not limit the structure of the front cover 2 to a single structure. There are many ways to implement the main cover 21, telescopic bridge 22, sliding cover 23 and two protective nets 25 in the front cover 2. As long as the following three points are met: ① The telescopic bridge 22 can automatically extend to the building's exterior wall of the target window; ② The protective nets 25 can extend in conjunction with the telescopic bridge 22; ③ The sliding cover 23 can automatically cover the inflatable buffer strip 24.

[0057] To more clearly describe the main cover 21, the telescopic bridge 22, and the two protective nets 25, this embodiment provides a structural diagram of one type of front cover 2, as follows: Figure 5 , Figure 6 As shown, the protective net 25 is installed on multiple posts. Some posts are fixedly connected to the main cover 21, and the bottom of the remaining posts are slidably installed along the guide groove of the telescopic bridge 22. The telescopic bridge 22 is provided with a telescopic folding frame in the guide groove. The end of the telescopic folding frame facing the main cover 21 is connected to the main cover 21. The posts are connected to the X intersection point of the telescopic folding frame. When the telescopic bridge 22 is extended, the telescopic folding frame will be lengthened, thereby unfolding the folded section of the protective net 25.

[0058] The rescue process is as follows:

[0059] Step 1: The drone flies to the rescue level with one end of the front cover 2 facing the target window;

[0060] Step 2: The front cover 2 automatically flips down under the action of its power source, as shown in the following state. Figure 3 As shown, the power source for the front cover 2 can be a telescopic rod driven by a cylinder or a hydraulic cylinder;

[0061] Step 3: The first slide rail extends the telescopic bridge 22 until the inflatable buffer strip 24 contacts the building's exterior wall at the target window. The protective net 25 unfolds in conjunction with the telescopic bridge 22, as shown in the following state. Figure 7 As shown;

[0062] Step 4: The second slide rail extends the sliding cover 23 until it covers the inflatable buffer strip 24, and the flexible sealing strip at the end of the sliding cover 23 contacts the building's exterior wall, as shown in the image. Figure 8 As shown;

[0063] Step 5: The trapped personnel enter the manned cabin 1, and the drone retracts the sliding cover 23 and the telescopic bridge 22 in sequence, and then closes the front cover 2;

[0064] Step 6: The drone returns to the ground. Upon touchdown, the inflatable cushioning ball 11 provides cushioning, and the rear cover 3 automatically flips down under its power source, allowing trapped personnel to evacuate. The status is as follows: Figure 9 As shown.

[0065] A detailed comparison of this plan with the rescue capabilities of fire ladder trucks, rescue helicopters, and multi-rotor eVTOLs is shown in Tables 1 and 2, as follows:

[0070] In summary, this solution can overcome the height limitations of existing rescue equipment, enabling rapid rescue of people in super high-rise buildings; it can automatically connect to the exterior wall of the target window, providing an automated rescue solution that does not require operation by trapped personnel; it can improve the payload capacity and endurance of UAVs; and it can enhance navigation stability and anti-interference capabilities in complex environments.
