Description

Technical Field

[0001] This utility model belongs to the field of emergency firefighting drone technology, specifically, it relates to a drone for urban emergency firefighting. Background Technology

[0002] Currently, most firefighting methods involve using aerial ladder trucks to address fire problems in high-rise buildings. However, fire trucks are large and are often restricted by streets when responding to fire calls, making it difficult for them to navigate narrow streets and reach the fire scene in a timely manner to determine the number and location of trapped people and thus rescue them.

[0003] Traditional drones used for urban emergency firefighting still have the following problems when in use:

[0004] When firefighting drones are used for firefighting operations, the space is limited because they are operated in corridors or narrow passages. Some passages cannot be passed through normally, which affects the control personnel's ability to observe the fire and delays the firefighting operation. Utility Model Content

[0005] To address the issue that fire-fighting drones cannot conduct voice communication, thus failing to promptly calm trapped individuals and potentially leading to extreme behaviors, thereby reducing the device's versatility and the limitations of conventional fire-fighting drones operating in narrow passageways or corridors, hindering firefighting operations and affecting fire monitoring, the basic concept of this invention is as follows:

[0006] A drone for urban emergency firefighting includes a drone body and a support rod. A folding mechanism is provided around the drone body to control the rotational folding action of the support rod. The folding mechanism includes a connecting column. One inner end of the connecting column is fixedly connected to the outer side of the drone body. A rotating sleeve is movably sleeved on the column body. A crown gear is fixedly connected to the outer end of the rotating sleeve, and a sleeve gear is fixedly sleeved around the outer side of the rotating sleeve. The outer end of the connecting column is movably connected to the inner end of the support rod. The lower inner end of the support rod is fixedly connected to a gear, which corresponds to and meshes with the crown gear.

[0007] In a preferred embodiment of this utility model, one outer end of the support rod is fixedly connected to a power motor, and a propeller is fixedly connected to the transmission shaft at the upper end of the power motor.

[0008] In a preferred embodiment of this utility model, a rotating camera is fixedly installed at the top center of the drone body, four infrared sensors are fixedly installed on the outer periphery of the drone body, and a speaker is fixedly installed on the front of the drone body.

[0009] In a preferred embodiment of this utility model, a conversion motor is fixedly installed inside the center of the lower end of the drone body. The transmission shaft at the lower end of the conversion motor passes through the bottom of the drone body and is fixedly connected to a central frame at its end.

[0010] In a preferred embodiment of this utility model, a transmission ring is fixedly connected to the periphery of the central frame. The upper end of the transmission ring is provided with a plurality of toothed grooves, which correspond to and mesh with the sleeve gear.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention employs a foldable rotor support rod, which temporarily retracts and folds the rotor when encountering narrow passages. Simultaneously, an infrared sensor is activated to monitor the distance to surrounding obstacles, ensuring the drone's normal passage. Additionally, a speaker is added to the front of the drone to communicate with and provide guidance and psychological comfort to the person being rescued, thereby maximizing the success rate of the rescue.

[0013] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figures 1 to 5 As shown, a drone for urban emergency firefighting includes a drone body 1 and a support rod 6. A folding mechanism is provided on the periphery of the drone body 1. The folding mechanism is used to control the rotation and folding action of the support rod 6. The folding mechanism includes a connecting column 13. One inner end of the connecting column 13 is fixedly connected to the outer side of the drone body 1. A rotating sleeve 3 is movably sleeved on the column body of the connecting column 13. A crown gear 7 is fixedly connected to the outer end of the rotating sleeve 3. A sleeve gear 12 is fixedly sleeved on the periphery of the rotating sleeve. The outer end of the connecting column 13 is movably connected to the inner end of the support rod 6. The lower inner end of the support rod 6 is fixedly connected to a gear 11. The gear 11 corresponds to the crown gear 7 and meshes with it.

[0023] In this design, the present invention employs a foldable rotor support rod 6, which temporarily retracts and folds the rotor to a certain extent when encountering a narrow passage. At the same time, an infrared sensor is activated to monitor the distance to surrounding obstacles to ensure the normal passage of the drone. Additionally, a speaker 15 is added to the front of the drone to communicate with, guide, and provide psychological comfort to the person to be rescued, thereby maximizing the success rate of the rescue.

[0024] like Figures 1 to 5 As shown, in a specific embodiment, one end of the support rod 6 is fixedly connected to the power motor 5, and a propeller 4 is fixedly connected to the transmission shaft at the upper end of the power motor 5.

[0025] In this setup, the support rod 6 remains open during the use of this device to ensure the stability of the drone during high-speed travel.

[0026] like Figures 1 to 5 As shown, in a specific embodiment, a rotating camera 2 is fixedly installed at the top center of the drone body 1, four infrared sensors 8 are fixedly installed on the outer periphery of the drone body 1, and a speaker 15 is fixedly installed on the front of the drone body 1.

[0027] In this setup, slow driving at low speed, combined with the use of infrared sensor 8 for auxiliary distance measurement, compensates for the instability. When the rescue point is reached, communication can be established with the person being rescued via speaker 15. The rotating camera 2 can rotate at a large angle, reducing blind spots during the search.

[0028] like Figures 1 to 5 As shown, in a specific embodiment, a conversion motor 14 is fixedly installed inside the center of the lower end of the drone body 1. The transmission shaft at the lower end of the conversion motor 14 passes through the bottom of the drone body 1 and is fixedly connected to a central frame 16 at its end.

[0029] In this setup, when encountering a relatively narrow passage, the speed is reduced and the conversion motor 14 is activated. The transmission rod of the conversion motor 14 drives the center frame 16 to rotate.

[0030] like Figures 1 to 5 As shown, in a specific embodiment, a transmission ring 9 is fixedly connected to the periphery of the central frame 16. The upper end of the transmission ring 9 is provided with a plurality of tooth grooves 10, which correspond to the sleeve gear 12 and mesh with it.

[0031] In this configuration, the central frame 16 drives the transmission ring 9 to rotate synchronously, and drives the sleeve gear 12 to rotate through the tooth groove 10. The sleeve gear 12 drives the crown gear 7 to rotate synchronously through the rotating sleeve 3. The crown gear 7 drives the support rod 6 to fold and retract through the gear 11, reducing the space required for the wings to spread.

[0032] The implementation principle of a drone used for urban emergency firefighting in this embodiment is as follows:

[0033] This utility model employs a foldable rotor support rod 6, which allows the rotor to be temporarily retracted and folded to a certain extent when encountering relatively narrow passages. At the same time, an infrared sensor is activated to monitor the distance of surrounding obstacles to ensure the normal passage of the drone. Additionally, a speaker 15 is added to the front of the drone to communicate with and provide guidance and psychological comfort to the person to be rescued, thereby maximizing the success rate of the rescue.

[0034] When using this device, the support rod 6 remains extended to ensure the stability of the drone during high-speed travel. When encountering a narrow passage, the speed is reduced and the conversion motor 14 is activated. The transmission rod of the conversion motor 14 drives the central frame 16 to rotate, which in turn drives the transmission ring 9 to rotate synchronously. This, in turn, drives the sleeve gear 12 to rotate via the toothed groove 10. The sleeve gear 12 drives the crown gear 7 to rotate synchronously via the rotating sleeve 3. The crown gear 7, through the gear 11, drives the support rod 6 to fold and retract, reducing the space required for wing expansion. Although this results in a certain loss of stability, the slow, low-speed travel, combined with the use of the infrared sensor 8 for auxiliary ranging, compensates for this instability. Upon reaching the rescue point, communication with the person being rescued can be achieved via the speaker 15. The rotating camera 2 can rotate at a large angle, reducing blind spots during the search.
