Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) rescue, and in particular to a vehicle-mounted rotary-wing UAV high-rise rescue system and method. Background Art

[0002] In the existing technology, rotary-wing UAVs are widely used in the consumer field due to their advantages of low price, simple control, hovering, easy take-off and landing, and certain load capacity. At the same time, they are increasingly used in the rescue field. Multi-rotor UAVs based on mobile platforms are also widely used in civil and rescue fields due to their maneuverability and flexibility.

[0003] However, in high-rise rescue scenarios, the use of drones still has certain limitations. First, the drone has limited load capacity and cannot directly carry rescue personnel or heavy equipment upstairs for rescue. Especially in emergency situations, it is difficult for rescue personnel to rely on drones to quickly rescue people in distress. Another problem is that drones have limited hovering time in the air. Currently, most drones are powered by batteries. The batteries are heavy and have limited power, so they cannot stay in the air for a long time for rescue. Another problem is the stability control of drones. Currently, most drones are manually remotely controlled, but drones are at high altitudes, and it is difficult for pilots to observe visually. Drones are also easily affected by various air currents such as smoke, heat waves, and strong winds, which increases the difficulty of flight control. Therefore, current drones only play a simple observation role in rescue, or carry lightweight firefighting equipment, but cannot carry heavier firefighting equipment, nor can they carry out emergency rescue of people in distress.

[0019] Furthermore, a concave structure is provided in the tail bearing platform 6 , which is engaged and fixed with the building fixing device 4 and the rotary-wing UAV 3 .

[0020] Furthermore, the concave structure also includes: a storage space for sundries; The sundries storage space is used for placing the rescue rope 11.

[0021] Optionally, the inflation method of the fixed air cushion 9 includes: pre-inflation pressure expansion, explosive inflation, etc.

[0022] Preferably, the motor 7 operates according to a control command sent by the target rescuer.

[0023] Optionally, the material of the fixing body 8 is any one of alloy and steel.

[0024] Specifically, the fixed body 8 is used to carry rescuers, rescue facilities and rescued persons, the fixed air cushion 9 is used to provide sufficient positive pressure required by the fixed body 8, and the pulley 10 cooperates with the motor 7 on the tail carrying platform 6 to retract and release the rescue rope 11 under the control of the rescuers.

[0025] Furthermore, taking high-rise rescue as an example, this system mainly utilizes the characteristics of drones, such as low cost, rapid response, simple operation, and a certain load capacity. This system includes a rotorcraft drone 3 for quickly carrying and installing rescue facilities, and a building fixing device 4 for fixing at the installation position 2, and a carrying vehicle 5 for fixed storage and transportation of the rotorcraft drone 3 and the building fixing device 4 during non-mission periods, and a rescue rope 11 for use by rescuers after the building fixing device 4 and the installation position 2 are reliably fixed. The building fixing device 4 includes a fixed body 8, a fixed air cushion 9 that provides positive pressure, and a pulley 10. The carrying vehicle 5 includes a rear carrying platform 6, and a motor 7 that assists rescuers in controlling the retraction and release of the rescue rope 11 during the rescue phase.

[0026] Preferably, the rotary-wing UAV 3 has sufficient carrying capacity, can carry the building fixture 4 and the rescue rope 11, and can still maintain stable controllability and certain maneuverability in the case of a relatively harsh rescue site environment. At the same time, the rotary-wing UAV 3 can provide image references for rescue personnel to assist rescue personnel in finding available installation positions 2, and can search for available installation positions 2 on the target building 1 in a controlled, semi-autonomous and autonomous manner under the control of the rescue personnel. At the same time, preferably, after assisting rescue personnel in finding available installation positions 2 on the target building 1, the carried building fixture 4 can be placed on the available installation positions 2 on the target building 1 in a controlled, semi-autonomous and autonomous manner under the control of the rescue personnel, and can be returned to the carrying vehicle 5 in a controlled, semi-autonomous and autonomous manner as needed under the command of the rescue personnel, or provide appropriate assistance to the rescue personnel, including but not limited to signal transmission, image monitoring, etc.

[0027] Furthermore, the building fixing device 4 includes a fixing body 8, a fixing air cushion 9 providing positive pressure, and a pulley 10. Among them, in order to have sufficient load capacity, the fixing body 8 is preferably made of high-strength alloy or steel. At the same time, in order to adapt to different buildings 1 with different installation positions 2, and different sizes and thicknesses, the fixing body 8 preferably adopts the principle of greater thickness compatibility and has a larger size adjustment space. At the same time, in order to meet the rescue needs of rescue personnel after the building fixing device 4 is fixed, the pulley 10 needs to be at a certain distance from the wall of the target building 1, and the fixing body 8 preferably adopts a "∏" design. At the same time, in order to meet the above-mentioned fixed body 8 has a wide compatibility with walls of different thicknesses while maintaining the fixing reliability of the fixed body 8 to the installation position, the fixed air cushion 9 can be controlled, semi-autonomous and autonomously started after the fixed body 8 is placed by the rotor drone 3, and is quickly inflated by a fast inflation method including but not limited to explosive inflation, and can maintain pressure for a long time after inflation is completed, meeting the rescue needs of rescue personnel for a long time. At the same time, after the fixed air cushion 9 is inflated, it can provide sufficient positive pressure so that the entire building fixing device 4 can be firmly fixed on the available installation position 2 on the target building 1. To achieve the above purpose, the fixed air cushion 9 is made of reliable, airtight, wear-resistant and low-cost materials. In addition, the pulley 10 needs to maintain a long-term reliable connection with the rescue rope, and reduce the damping as much as possible during the sliding process to increase the maximum load capacity of the entire rescue device. It uses high-standard bearing steel and undergoes appropriate treatment, including but not limited to surface treatment, lubrication and other measures. At the same time, the pulley should be connected to the fixed body in a reliable connection method to improve the overall reliability.

[0028] Preferably, the carrying vehicle 5 includes the basic functions of an ordinary civilian vehicle, and the tail is modified and installed with a tail carrying platform 6, which can provide sufficient fixing measures and safety precautions for the rotor drone 3, the building fixing device 4, the motor 7 and the rescue rope 11 during the storage and transportation stages. Among them, the tail carrying platform 6 is located on the carrying vehicle 5, and the motor 7 is installed at the front. In order to meet the rescue personnel's control of the retraction and release of the rescue rope 11, it needs to have a variety of operating capabilities, including but not limited to a variety of operating methods including close-range panel operation and long-range wireless operation, so as to meet the diverse rescue needs of the rescue site. At the same time, in order to better place the rotor drone 3, the building fixing device 4 and the rescue rope 11. In addition, the rear part of the tail carrying platform 6 has a suitable concave structure to realize the limit of the rotor drone 3, the building fixing device 4 and the rescue rope 11, and at the same time, an appropriate and suitable connecting and fixing part is added. The two cooperate with each other to realize that the rotor drone 3, the building fixing device 4 and the rescue rope 11 and other rescue devices can be safely, stably and reliably fixed on the tail carrying platform 6 during the non-mission storage and transportation stage.

[0029] Furthermore, the tail load-bearing platform 6 has sufficient load-bearing capacity and power supply to provide the load and power required for daily storage, transportation and rescue stages. At the same time, in order to meet the maximum load requirements and safety protection needs of rescuers during the rescue stage, the motor 7 located at the front section of the tail load-bearing platform 6 adopts a large torque motor to provide sufficient torque supply. At the same time, certain limiting measures can be adopted to avoid abnormal release of the rescue rope caused by a significant increase in load in a short period of time, so as to provide system safety.

[0030] Furthermore, the specific steps of a vehicle-mounted rotary-wing drone high-rise rescue method provided in this embodiment are as follows: S1: Move the carrying vehicle 5 to a suitable position in front of the target building 1; S2: Start the rotor drone 3, take off and carry the building fixture 4, and at the same time find an installation position 2 on the building 1 that can be used by the building fixture 4.

[0031] S3: The rotor drone 3 places the building fixture 4 at a suitable location and performs subsequent operations under the control of the rescue personnel as needed; S4: After the building fixing device 4 is placed at a suitable position, the fixing air cushion 9 is quickly inflated to provide sufficient pressure so that the building fixing device 4 is firmly fixed; S5: The motor 7 located at the rear of the load-bearing vehicle is started, and the rescue rope 11 is controlled to be retracted and released, and the rescue operation begins.

[0032] The beneficial effects of the present invention are as follows: The present invention achieves the fixation of the pulley by fixing the main body and the fixed air cushion, thereby providing a reliable supporting point for rescue; and achieves the rapid placement and fixation of the building fixing device by the rotor drone, thereby shortening the rescue time.
