Description

Technical Field

[0001] This invention relates to the field of drone launcher technology, specifically a portable small drone launcher. Background Technology

[0002] Fire extinguishing drones are unmanned aerial vehicle (UAV) systems specifically designed for fire response. Combining modern firefighting technology with innovative design concepts, they can play a crucial role in various fire scenarios. A typical fire extinguishing drone consists of a drone platform, a fire extinguishing bomb mounting system, a navigation system, a control system, and a communication system. The drone platform carries the fire extinguishing bombs to the designated location; the fire extinguishing bomb mounting system is used to mount and deploy the bombs; the navigation system ensures the drone accurately reaches the fire source; the control system controls the drone's flight and bomb deployment; and the communication system enables information transmission between the drone and the ground control station.

[0003] The process of loading fire extinguishing bombs into a drone usually requires selecting the appropriate fire extinguishing bomb based on the type of fire on site and the required fire extinguishing effect. Then, the mounting point is located, and the fire extinguishing bomb is installed onto the pod or mounting point in the correct direction and manner to ensure that the connection between the fire extinguishing bomb and the drone is firm and reliable, and to prevent it from falling off or shaking during flight. However, the installation of existing fire extinguishing bombs by drones is very complicated and troublesome. When operating in complex environments near fire sites, factors such as weather and terrain may affect the fire extinguishing bombs, leading to hasty replacement and insecure installation, which in turn affects the fire extinguishing effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable miniature drone launcher, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable small unmanned aerial vehicle (UAV) launcher, comprising an UAV body, a fixing block fixedly connected to the bottom of the UAV body, a launching mechanism disposed below the fixing block, and the launching mechanism being detachably connected to the fixing block.

[0006] Preferably, the launching mechanism includes a movable block, a guide tube, a fire extinguishing bomb, a mounting assembly, side plates, a support frame, an insert block, a slot, and a synchronous telescopic assembly. The bottom of the movable block is fixedly connected to the guide tube, and the fire extinguishing bomb is disposed inside the guide tube. The guide tube is provided with a mounting assembly for suspending the fire extinguishing bomb. Side plates are symmetrically arranged on both sides of the movable block. The movable block is provided with a synchronous telescopic assembly for controlling the synchronous outward extension and retraction of the two side plates. A support frame is installed on the outer side of the side plate, and an insert block is fixedly connected to the inner side of the side plate. The fixed block has a slot that matches the insert block. When the insert block is fully inserted into the slot, the side plate fits against the fixed block and the movable block, so that the fixed block and the movable block are fixed to each other.

[0007] Preferably, the bottom surface of the fixed block is set as a plane, the top surface of the movable block is set as a plane, and the bottom surface of the fixed block matches the top surface of the movable block.

[0008] Preferably, the support frame includes a support rod, a crossbar, and an anti-slip sleeve. One end of the support rod is fixedly connected to the side plate, and the other end of the support rod is fixedly connected to the crossbar. The crossbar is fitted with an anti-slip sleeve.

[0009] Preferably, the horizontal height of the crossbar is lower than the lowest point of the guide tube, and two anti-slip sleeves are provided, with the two anti-slip sleeves located at both ends of the crossbar.

[0010] Preferably, the mounting assembly includes a housing, a hook, a hanging ring, hot melt adhesive, a heating wire, a power supply, and a microcontroller. The hook is made of metal, and its vertical portion extends into the housing and is fixedly connected to it. The housing contains the heating wire, the power supply, and the microcontroller. The heating wire is wound around the vertical portion of the hook. Both the heating wire and the power supply are electrically connected to the microcontroller. The microcontroller controls the heating wire to heat the hook. The bottom end of the hanging ring is fixedly connected to the fire extinguishing bomb. The upper part of the hanging ring is made of hot melt adhesive. The hanging ring is hung on the hook, and under the action of gravity, the hot melt adhesive portion of the hanging ring comes into contact with the hook. The microcontroller controls the heating wire to heat up, which heats the hook, causing the hook to heat up and melt the hot melt adhesive. The melting of the hot melt adhesive causes the fire extinguishing bomb to be launched downwards along the guide tube.

[0011] Preferably, the synchronous telescopic assembly includes a drive structure, a main shaft, a take-up reel, a steel cable, a screw, and a telescopic column. Both ends of the main shaft are fixedly connected to screws. The telescopic column has a threaded hole matching the screw, and the screw is threaded with the telescopic column. The outer end of the telescopic column is fixedly connected to a side plate. The middle of the main shaft is fixedly connected to the take-up reel. One end of the steel cable is fixedly connected to the take-up reel. The movable block has a through hole for the steel cable to pass through. The end of the steel cable away from the take-up reel passes through the through hole and is fixedly connected to the outer shell of the mounting assembly. A drive structure for driving the main shaft to rotate is provided on one side of the main shaft. When both side plates extend completely outwards, the take-up reel releases the line, lengthening the steel cable and causing the outer shell to move the hook downwards until the hook extends out of the guide tube opening, thus facilitating the mounting of the fire extinguishing bomb.

[0012] Preferably, the drive structure includes a drive motor, a drive wheel, a driven wheel, and a transmission belt. The drive wheel is fixedly connected to the output end of the drive motor, the driven wheel is fixedly connected to the main shaft, and a transmission belt drives between the drive wheel and the driven wheel.

[0013] This invention provides a portable miniature drone launcher. It has the following advantages: 1. This portable mini drone launcher, through its launch mechanism, can pre-prepare various launch mechanisms equipped with different models and sizes of fire extinguishing bombs. Upon arrival at the scene, based on observations of the fire intensity, wind direction, and terrain, a launch mechanism with a suitable fire extinguishing bomb is selected. The movable block is aligned with the fixed block of the drone body, and then the synchronous telescopic assembly is activated to retract the two side plates inward until the insert block is inserted into the slot. When the insert block is fully inserted into the slot, the side plates are in contact with the fixed and movable blocks, securing them together. This allows for quick selection and installation of suitable fire extinguishing bombs. Furthermore, while one person operates the drone for fire extinguishing, another person can pre-install suitable fire extinguishing bombs on other spare launch mechanisms. Sufficient installation time ensures secure installation. After the drone returns from its launch, the synchronous telescopic assembly is activated to extend the two side plates outward, and the above steps are repeated to install the spare launch mechanism. This allows for rapid on-site replacement of fire extinguishing bombs. The installation is simple, convenient, and efficient, minimizing the risk of insecure installation due to hasty installation in harsh environments.

[0014] 2. This portable small drone launcher, through the setting of the mounting mechanism, when it is necessary to launch fire extinguishing bombs, the microcontroller controls the heating wire to heat up, the heating wire heats the hook, causing the hook to heat up and melt the hot melt adhesive, and the melted hot melt adhesive causes the fire extinguishing bomb to be launched downward along the guide tube.

[0015] 3. This portable mini-drone launcher, through the setting of a synchronous telescopic assembly, uses a main shaft to drive two screws to rotate synchronously, thereby synchronously extending and retracting the two side plates. Simultaneously, the rotation of the main shaft drives the take-up reel. When the two side plates extend outwards, the take-up reel releases the line, lengthening the steel cable and causing the hook to descend until it extends from the opening of the guide tube. At this point, the hook is fully exposed, allowing for easy attachment of the fire extinguishing bomb's hanging ring. Installation is very convenient. Furthermore, when the side plates retract inwards, the main shaft reverses, driving the take-up reel to reel in the line, causing the steel cable to wind up and the hook to rise, automatically loading the fire extinguishing bomb completely into the guide tube. The launcher can automatically adjust the hook position based on whether the launching mechanism is mounted on the drone body, further facilitating fire extinguishing bomb installation and making it more suitable for on-site use.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] This invention provides a portable miniature drone launcher, such as... Figure 1-7 As shown, the device includes a drone body 1, a fixing block 2 fixedly connected to the bottom of the drone body 1, a launching mechanism located below the fixing block 2, and the launching mechanism and the fixing block 2 are detachably connected.

[0020] In some embodiments, such as Figure 3-5 As shown, the launching mechanism includes a movable block 3, a guide tube 9, a fire extinguishing bomb 8, a mounting assembly, side plates 4, a support frame, an insert block 10, a slot 11, and a synchronous telescopic assembly. The bottom of the movable block 3 is fixedly connected to the guide tube 9, and the fire extinguishing bomb 8 is placed inside the guide tube 9. The guide tube 9 is equipped with a mounting assembly for suspending the fire extinguishing bomb 8. Side plates 4 are symmetrically arranged on both sides of the movable block 3. The movable block 3 is equipped with a synchronous telescopic assembly for controlling the synchronous outward extension and retraction of the two side plates 4. A support frame is installed on the outer side of the side plate 4, and an insert block 10 is fixedly connected to the inner side of the side plate 4. A slot 11 matching the insert block 10 is opened on the fixed block 2. When the insert block 10 is fully inserted into the slot 11, the side plate 4 fits against the fixed block 2 and the movable block 3, so that the fixed block 2 and the movable block 3 are fixed to each other.

[0021] By setting up the launching mechanism, various launching mechanisms equipped with different types and sizes of fire extinguishing bombs 8 can be prepared in advance. Upon arrival at the scene, based on observations of the fire intensity, wind direction, and terrain, a launching mechanism equipped with a suitable fire extinguishing bomb 8 is selected. The movable block 3 is aligned with the fixed block 2 of the drone body 1, and then the synchronous telescopic assembly is activated to retract the two side plates 4 inward until the insert block 10 is inserted into the slot 11. When the insert block 10 is fully inserted into the slot 11, the side plate 4 fits against the fixed block 2 and the movable block 3, thus fixing the fixed block 2 and the movable block 3 together, thereby enabling rapid selection of the appropriate launching mechanism. The appropriate fire extinguishing bomb 8 can be installed. While one person is operating the drone for firefighting, another person can pre-install the appropriate fire extinguishing bomb 8 on another spare launching mechanism. There is sufficient time for installation, and there will be no problem with the installation being insecure. After the drone returns after firing, the synchronous telescopic component is activated to extend the two side plates 4 outwards. The above steps are repeated to install the spare launching mechanism. This allows for quick replacement of the fire extinguishing bomb 8 on site. The installation is simple and convenient, with high efficiency, and it is less likely to result in insecure installation due to hasty installation of the fire extinguishing bomb 8 in harsh on-site environments.

[0022] The bottom surface of the fixed block 2 is set as a plane, the top surface of the movable block 3 is set as a plane, and the bottom surface of the fixed block 2 matches the top surface of the movable block 3.

[0023] The support frame includes a support rod 5, a crossbar 6, and an anti-slip sleeve 7. One end of the support rod 5 is fixedly connected to the side plate 4, and the other end of the support rod 5 is fixedly connected to the crossbar 6. The crossbar 6 is fitted with an anti-slip sleeve 7.

[0024] The horizontal height of the crossbar 6 is lower than the lowest point of the guide tube 9. Two anti-slip sleeves 7 are provided, and the two anti-slip sleeves 7 are provided at both ends of the crossbar 6.

[0025] In some embodiments, such as Figure 7As shown, the mounting assembly includes a housing 19, a hook 18, a hanging ring 16, hot melt adhesive 17, a heating wire 20, a power supply 22, and a microcontroller 21. The hook 18 is made of metal, and its vertical portion extends into the housing 19 and is fixedly connected to it. The heating wire 20, the power supply 22, and the microcontroller 21 are installed inside the housing 19. The heating wire 20 is wound around the vertical portion of the hook 18. Both the heating wire 20 and the power supply 22 are electrically connected to the microcontroller 21, which controls the heating. The heating wire 20 heats the hook 18. The bottom end of the hanging ring 16 is fixedly connected to the fire extinguishing bomb 8. The upper part of the hanging ring 16 is made of hot melt adhesive 17. The hanging ring 16 is hung on the hook 18, and under the action of gravity, the hot melt adhesive 17 part of the hanging ring 16 is in contact with the hook 18. The microcontroller 21 controls the heating wire 20 to heat up. The heating wire 20 heats the hook 18, causing the hook 18 to heat up and melt the hot melt adhesive 17. The melting of the hot melt adhesive 17 causes the fire extinguishing bomb 8 to be launched downward along the guide tube 9.

[0026] By setting up the mounting mechanism, when it is necessary to launch the fire extinguishing bomb 8, the microcontroller 21 controls the heating wire 20 to heat up. The heating wire 20 heats the hook 18, causing the hook 18 to heat up and melt the hot melt adhesive 17. The melting of the hot melt adhesive 17 causes the fire extinguishing bomb 8 to be launched downwards along the guide tube 9.

[0027] In some embodiments, such as Figure 5-6 As shown, the synchronous telescopic assembly includes a drive structure, a main shaft 13, a take-up reel 15, a steel cable 27, a screw 14, and a telescopic column 12. Both ends of the main shaft 13 are fixedly connected to the screw 14. The telescopic column 12 has threaded holes matching the screw 14, and the screw 14 is threaded with the telescopic column 12. The outer end of the telescopic column 12 is fixedly connected to the side plate 4. The take-up reel 15 is fixedly connected to the middle of the main shaft 13, and one end of the steel cable 27 is fixedly connected to the take-up reel 15. Block 3 has a through hole for the steel cable 27 to pass through. The end of the steel cable 27 away from the take-up reel 15 passes through the through hole and is fixedly connected to the housing 19 of the hanging assembly. A drive structure for driving the main shaft 13 to rotate is provided on one side of the main shaft 13. When the two side plates 4 are fully extended outward, the take-up reel 15 releases the line, causing the steel cable 27 to lengthen, which causes the housing 19 to drive the hook 18 to move downward until the hook 18 extends out of the opening of the guide tube 9, thereby facilitating the hanging of the fire extinguishing bomb 8.

[0028] By using a synchronous telescopic assembly, the main shaft 13 drives two screws 14 to rotate synchronously, thereby synchronously extending and retracting the two side plates 4. Simultaneously, the rotation of the main shaft 13 drives the rotation of the take-up reel 15. When the two side plates 4 extend outward, the take-up reel 15 releases the line, lengthening the steel cable 27, causing the hook 18 to descend until it extends from the opening of the guide tube 9. At this point, the hook 18 is fully exposed, making it easy to hang the hanging ring 16 on the fire extinguishing bomb 8. Installation is very convenient. Moreover, when the side plates 4 retract inward, the main shaft 13 reverses, driving the take-up reel 15 to take in the line, causing the steel cable 27 to wind up and lifting the hook 18, thus automatically loading the fire extinguishing bomb 8 completely into the guide tube 9. The position of the hook 18 can be automatically adjusted according to whether the launching mechanism is installed on the unmanned aerial vehicle body 1, further facilitating the installation of the fire extinguishing bomb 8 and making it more suitable for on-site use.

[0029] In some embodiments, such as Figure 5 As shown, the drive structure includes a drive motor 23, a drive wheel 24, a driven wheel 25, and a transmission belt 26. The drive wheel 24 is fixedly connected to the output end of the drive motor 23, and the driven wheel 25 is fixedly connected to the main shaft 13. The drive wheel 24 and the driven wheel 25 are connected by a transmission belt 26.

[0030] Working principle: The launching mechanism allows for the pre-preparation of various launching mechanisms pre-loaded with different types and sizes of fire extinguishing bombs 8. Upon arrival at the scene, based on observations of the fire intensity, wind direction, and terrain, a launching mechanism equipped with a suitable fire extinguishing bomb 8 is selected. The movable block 3 is aligned with the fixed block 2 of the drone body 1. Then, the synchronous telescopic assembly is activated to retract the two side plates 4 inwards until the insert block 10 is inserted into the slot 11. When the insert block 10 is fully inserted into the slot 11, the side plate 4 fits against the fixed block 2 and the movable block 3, thus fixing the fixed block 2 and the movable block 3 together, enabling rapid... Select the appropriate fire extinguishing bomb 8 for installation. While one person is operating the drone for firefighting, another person can pre-install the appropriate fire extinguishing bomb 8 on another spare launcher. There is sufficient time for installation, and there will be no problem with the installation being insecure. After the drone returns after firing, activate the synchronous telescopic assembly to extend the two side plates 4 outwards. Repeat the above steps to install the spare launcher. This allows for quick replacement of the fire extinguishing bomb 8 on site. The installation is simple and convenient, with high efficiency, and it is less likely to result in insecure installation due to hasty installation of the fire extinguishing bomb 8 in harsh on-site environments.
