Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting drones, and in particular to a fire-fighting drone with an active cooling system and capable of resisting high temperatures when operating in confined spaces. Background Art

[0002] With the acceleration of urbanization and the rapid development of industry, various types of buildings are becoming increasingly complex, and fire hazards are also increasing. In fire rescue work, confined space fires have brought great difficulties and challenges to firefighting and rescue due to their closed environment, high temperature, thick smoke, and low visibility. Firefighters are required to enter the fire scene for reconnaissance and firefighting, which is not only inefficient but also poses a serious threat to the life safety of firefighters. In a confined space with high temperature, toxicity, and lack of oxygen, firefighters are easily injured or even their lives are in danger. UAVs have the advantages of strong maneuverability, flexible operation, and remote control. They can quickly reach the fire scene for reconnaissance and monitoring.

[0003] However, with current technology, when ordinary drones face a fire in a confined space, due to the extremely high temperature in the confined space, their electronic components are easily affected by the high temperature, resulting in performance degradation or even damage. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a high-temperature resistant firefighting drone for confined space operations with an active cooling system, which solves the problem that electronic components in drones are easily affected by high temperatures, resulting in performance degradation or even damage.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-temperature resistant fire-fighting drone for confined space operations with an active cooling system, comprising a shell, electronic components fixedly connected to the interior of the shell, a heat dissipation assembly provided inside the shell, temperature sensors provided inside and outside the shell, a camera fixedly connected to the interior of the shell, a transparent glass plate provided on the outer wall of the camera, the outer wall of the transparent glass plate fixedly connected to the outer wall of the shell, support frames fixedly connected to both sides of the outer wall of the shell, a protective frame provided on the outer wall of the support frame, a power assembly provided on the lower surface of the support frame, and a communication assembly provided inside the shell.

[0006] Preferably, the shell includes an aluminum-plated film and porous vacuum silicon, the aluminum-plated film is located on the outer layer of the shell, the porous vacuum silicon is located on the inner layer of the shell, and insulating thermal conductive glue is provided between the porous vacuum silicon and the electronic components.

[0007] Preferably, the heat dissipation assembly dissipates heat from electronic components inside the housing via a coolant.

[0008] Preferably, the outer layer of the protective frame is provided with an aluminum-plated film, and the inner layer of the protective frame is provided with aerogel.

[0009] Preferably, the power assembly includes a motor, the upper surface of the motor is fixedly connected to the lower surface of the support frame, and the output end of the motor is fixedly provided with a blade.

[0010] Preferably, the communication component includes an optical fiber, an outer wall of the optical fiber is fixedly connected to the inside of the housing, and the optical fiber is communicatively connected to the electronic components inside the housing.

[0011] Preferably, an exhaust duct is provided on the lower surface of the support frame, and the air outlet position of the exhaust duct covers the position of the motor.

[0012] Preferably, ultrasonic collision avoidance sensors are provided on all four outer walls of the housing.

[0013] Working principle: When the drone is needed, firefighters use the internal electronic components to control the opening of the drone, thereby driving it to rotate and control the overall movement of the drone at the fire scene. At the same time, the captured and recorded survey data are transmitted through data transmission to avoid the influence of electromagnetic interference, signal attenuation and obstruction, ensuring the stable transmission of control signals, thereby stably executing flight missions and conducting survey operations.

[0014] The present invention provides a high-temperature-resistant firefighting drone for confined space operations with an active cooling system. It has the following beneficial effects: 1. In the present invention, the aluminum-plated film is located on the outer layer of the shell, which can reflect most of the heat radiation, reduce the heat transfer from the external high temperature to the interior of the drone, and lower the shell temperature. The porous vacuum silicon is located on the inner layer, which can block the external heat transfer and protect the electronic components. At the same time, it can absorb and conduct the heat of the components. In combination with the insulating thermal conductive adhesive, it can achieve efficient heat dissipation, extend the life of the electronic components, and improve the working stability and reliability of the drone in high temperature environments.

[0015] 2. The present invention controls the tank valve through the sensor inside the shell to automatically adjust the coolant flow rate, so as to quickly absorb the heat emitted by the electronic components, so that the electronic components can maintain stable operation within the appropriate temperature range. The coolant circulates inside the UAV, promptly taking away the heat generated by the electronic components and isolating the hot air outside the shell, thereby maintaining the normal development of survey work such as flight control and communication transmission, and improving the working efficiency of the UAV in complex environments.

[0016] 3. The present invention uses optical fiber for communication transmission, which has a high transmission rate and large bandwidth, and can realize the rapid transmission of large amounts of data, ensuring that the data is transmitted to the ground control station quickly and stably, thereby timely and accurately grasping the situation at the fire scene. At the same time, optical fiber communication will not have problems such as signal congestion, excessive delay or data loss, and can transmit data even without wireless signals, greatly improving the stability and reliability of communication.

[0019] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see the attached Figure 1 An embodiment of the present invention provides a high-temperature resistant firefighting drone for confined space operations with an active cooling system, comprising a shell 1, electronic components fixedly connected to the interior of the shell 1, a heat dissipation component provided inside the shell 1, temperature sensors provided inside and outside the shell 1, a camera 2 fixedly connected to the interior of the shell 1, a transparent glass plate 3 provided on the outer wall of the camera 2, an outer wall of the transparent glass plate 3 fixedly connected to the outer wall of the shell 1, support frames 4 fixedly connected to the outer walls of both sides of the shell 1, a protective frame 5 provided on the outer wall of the support frame 4, a power component provided on the lower surface of the support frame 4, and a communication component provided inside the shell 1.

[0021] Specifically, the shell 1 can support the position of electronic components, which include the drone's control unit, energy battery and communication unit, etc., and the electronic components are placed inside the shell 1. The temperature sensors inside and outside the shell 1 can monitor the working temperature of the electronic components and the external environment in real time, which is convenient for starting heat dissipation measures, as well as understanding the fire environment temperature to ensure the stable operation of the drone. At the same time, the electronic components are dissipated by the heat dissipation components inside the shell 1, which can ensure that the electronic components work at an appropriate temperature and have more stable performance, thereby improving the stability of the fire investigation task. The camera 2 is embedded in the inside of the shell 1, and the transparent glass plate 3 can prevent dust, water vapor, small particles and other impurities from directly contacting the camera 2 during the flight of the drone, avoiding scratches, wear or pollution to its lens, thereby ensuring the imaging quality of the camera 2, isolating the impact of the external environment on the camera 2, ensuring the reliability of the camera 2 operation, and thus ensuring the accuracy of the drone's investigation data.

[0022] The shell 1 includes an aluminum-plated film and porous vacuum silicon. The aluminum-plated film is located on the outer layer of the shell 1, and the porous vacuum silicon is located on the inner layer of the shell 1. Insulating thermal conductive glue is provided between the porous vacuum silicon and the electronic components.

[0023] Specifically, the aluminum-coated film is located on the outer layer of the outer shell 1. The aluminum-coated film has the characteristics of high reflectivity and can reflect most of the heat radiation, reducing the heat transfer from the external high temperature environment to the interior of the drone, effectively reducing the temperature of the outer shell 1 of the drone at the high temperature fire scene, thereby significantly improving the adaptability of the drone in high temperature environments. The porous vacuum silicon is located in the inner layer of the outer shell 1, and mainly plays the dual role of heat insulation and heat dissipation. There are a large number of tiny pores inside the porous vacuum silicon, and these pores are in a vacuum state. It can effectively block external heat from entering the interior of the drone, protect the internal electronic components from high temperature, and maintain the normal operating temperature of the electronic components. At the same time, the large specific surface area and good thermal conductivity of the porous vacuum silicon enable it to quickly absorb the heat generated by the electronic components and conduct the heat out through its own structure. Combined with the insulating thermal conductive glue, the porous vacuum silicon can quickly conduct the heat of the electronic components to achieve efficient heat dissipation, thereby extending the service life of the electronic components and improving the working stability and reliability of the drone in high temperature environments.

[0024] The heat dissipation assembly dissipates heat from the electronic components inside the housing 1 through the coolant.

[0025] Specifically, the coolant in the heat dissipation component passes through the tank inside the shell 1. There is a valve on the tank, which can automatically adjust the coolant flow according to the temperature sensor inside the shell 1. It can quickly absorb the heat emitted by the electronic components and keep them within the appropriate operating temperature range, ensuring the stable operation of the electronic components, thereby making the flight attitude control of the drone more precise, the communication transmission stable and reliable, and ensuring the smooth execution of various tasks. At the same time, the coolant circulates inside the drone, taking away the heat generated by the electronic components in time, isolating the hot air outside the shell 1, thereby maintaining the drone's flight control and communication transmission survey work.

[0026] The outer layer of the protective frame 5 is provided with an aluminum-plated film, and the inner layer of the protective frame 5 is provided with aerogel.

[0027] Specifically, the aluminum-plated film is placed on the outer layer of the protective frame 5, which can prevent the external hot air flow and thermal radiation from conducting heat to the support frame 4 during flight, thereby affecting the electronic components inside the shell 1. The thermal insulation performance of the aerogel in the inner layer of the protective frame 5 can absorb the heat generated by the support frame 4 and surrounding components, and disperse the heat evenly through its own heat conduction, while blocking the influence of external high temperature on internal components, making it easier for heat to dissipate into the surrounding environment, thereby improving the overall heat dissipation efficiency of the drone and ensuring the stable operation of the drone's power system.

[0028] The power assembly includes a motor 6 , the upper surface of the motor 6 is fixedly connected to the lower surface of the support frame 4 , and a blade 7 is fixedly provided at the output end of the motor 6 .

[0029] Specifically, the support frame 4 provides fixed support for the motor 6, and the electronic components inside the housing 1 can control the start of the motor 6 through signals, so that the motor 6 drives the blades 7 to rotate, driving the entire drone to perform mobile surveys at the fire scene.

[0030] The communication component includes an optical fiber 8 , the outer wall of the optical fiber 8 is fixedly connected to the inside of the housing 1 , and the optical fiber 8 is communicatively connected with the electronic components inside the housing 1 .

[0031] Specifically, optical fiber 8 has an extremely high transmission rate and bandwidth, and can realize the rapid transmission of large amounts of data. Optical fiber 8 is installed in a releaser. During the forward flight of the drone, the optical fiber 8 is released through a code disk. The code disk can record the length of the released optical fiber 8. Combined with the electronic compass on the drone, the position of the drone can be obtained. In fire rescue scenarios, drones need to transmit high-definition images, videos, etc. in real time. The application of optical fiber 8 can ensure that these data can be transmitted stably to the ground control station at an extremely fast speed, so that commanders can understand the actual situation at the fire scene in a timely and accurate manner, and provide strong support for the formulation of scientific and reasonable rescue plans. Compared with traditional wireless communication methods, optical fiber 8 communication will not have problems such as signal congestion, excessive delay or data loss. Data transmission is performed without wireless signals, thereby improving the stability and reliability of communication.

[0032] An exhaust duct 9 is provided on the lower surface of the support frame 4 , and the air outlet position of the exhaust duct 9 covers the position of the motor 6 .

[0033] Specifically, the motor 6 is inverted and located under the four exhaust ducts 9, covered by the exhaust air. The exhaust air can be used to achieve efficient heat dissipation, reduce the temperature of the motor 6, and keep it in a suitable operating temperature range at all times, thereby ensuring the stable operation of the motor 6 and improving the overall reliability and work efficiency of the fire-fighting drone.

[0034] Ultrasonic collision avoidance sensors 10 are provided on all four outer walls of the housing 1 .

[0035] Specifically, ultrasonic collision avoidance sensors 10 are provided on all four outer walls of the shell 1 of the firefighting drone, which can monitor the surrounding environment in real time and in all directions. When the drone moves forward, left, right, up and down, through the five ultrasonic collision avoidance sensors 10, whether it is close to a building or encounters moving obstacles such as fallen objects caused by a fire, the ultrasonic collision avoidance sensors 10 can capture the reflected ultrasonic waves in time, quickly calculate the distance to the obstacle, and promptly feed back to the flight control system, allowing the drone to quickly make evasive actions, effectively avoid collision accidents, and ensure flight safety and mission execution.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
