Benefits of technology

[0020]Before the drone begins firefighting operations, the irregularly shaped limiting block is slidably installed into the sliding groove. When the block enters the groove, it presses against the moving top rod. This pressure causes the moving top rod to move, which in turn moves the connecting plate. The moving plate, through a connecting rod, moves the horizontal rack, which in turn rotates the rotating gear. This rotation causes the lifting rack to move vertically. The lifting rack, through a lifting connecting rod, moves the lifting mounting plate downwards. The lifting mounting plate then moves the lifting limiting plate downwards, contacting the irregularly shaped limiting block. The lifting spring then compresses, and the irregularly shaped limiting block... When the positioning block is fully inserted into the sliding groove, the irregularly shaped limiting block and the lifting limiting plate disengage. The lifting spring pushes the lifting limiting plate downward to the opening of the sliding groove. The lifting limiting plate and the irregularly shaped block slide together, fixing the position of the irregularly shaped limiting block and fixing the fire extinguishing magazine below the mounting block. Through the sliding engagement between the irregularly shaped limiting block and the sliding groove, as well as the quick locking and unlocking of the lifting limiting plate, the staff can manually complete the disassembly and replacement of the fire extinguishing magazine on the ground without complicated tools or disassembly of the mounting structure, which significantly shortens the standby time of the drone to be put back into fire fighting.

Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a window-breaking fire extinguishing bomb dispenser mounted on a drone. Background Technology

[0002] Currently, drones, due to their maneuverability and rapid response, are widely used in firefighting, especially in scenarios where personnel cannot directly access the fire, such as fires on the exterior walls of high-rise buildings and fires involving hazardous chemicals. Drones carrying window-breaking fire extinguishing bombs have become an effective technological means of extinguishing fires. Existing drone fire extinguishing bomb delivery devices typically use a fixed mounting method, where the fire extinguishing bomb magazine is directly fixed to a mounting bracket under the drone's fuselage using bolts, clips, and other connectors. After flying to the target area, the firing mechanism sequentially deploys the fire extinguishing bombs to the fire point.

[0003] However, the existing technology still has the following shortcomings:

[0004] First, the loading and changing of fire extinguishing ammunition magazines is cumbersome, affecting the efficiency of continuous operations. Since fire extinguishing ammunition magazines are typically connected to the drone using bolts or clips, once all the ammunition is used, the drone must be landed, and personnel must use wrenches and other tools to remove the bolts or open the clips one by one to unload the empty magazine and replace it with a new one filled with fire extinguishing ammunition. This entire process is time-consuming, extending the drone's standby time before it can be taken back into the air for firefighting, which is detrimental to the crucial firefighting efforts where every second counts.

[0005] Second, the existing mounting structures are not convenient to assemble and disassemble, lacking a quick locking and unlocking mechanism. While traditional connection methods such as bolts and clips are sturdy, they are difficult to disassemble and install quickly, failing to meet the urgent needs of firefighters for rapid resupply and quick re-attack, thus limiting the combat effectiveness of drones in continuous firefighting missions.

[0006] Therefore, there is an urgent need for a mount-mounted window-breaking fire extinguishing grenade dispenser that allows for rapid disassembly and reassembly of the fire extinguishing magazine and enables the reloading operation to be completed without the drone landing, in order to improve the continuous operation capability and safety of drones. Summary of the Invention

[0007] The purpose of this invention is to provide a mountable window-breaking fire extinguishing grenade dispenser that enables rapid assembly and disassembly of the fire extinguishing ammunition magazine and allows for ammunition replacement without the need for a drone to land. This addresses the problems of cumbersome mounting and replacement operations of fire extinguishing ammunition magazines in existing technologies, which affect continuous operation efficiency, and the lack of convenient assembly and disassembly methods and rapid locking and unlocking mechanisms in existing mounting structures.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a window-breaking fire extinguishing bomb dispenser mounted on a drone, comprising a drone body, a mounting assembly, and a replacement assembly, wherein the mounting assembly comprises a rotating mounting block, a lifting plate, a lifting rope, a winding roller, and the mounting mounting block.

[0009] The rotating mounting block is rotatably mounted on the bottom surface of the UAV body. The bottom surface of the rotating mounting block has a mounting groove. The winding roller is rotatably mounted in the mounting groove. The lifting rope is wound on the winding roller. One end of the lifting rope is fixedly connected to the winding roller, and the other end is fixedly connected to the lifting plate. The lifting plate is fixedly connected to the mounting block.

[0010] The replacement component also includes a fire extinguishing ammunition magazine, an irregularly shaped limiting block, and a lifting limiting plate. The front end face of the mounting block is provided with a sliding groove. The irregularly shaped limiting block is slidably installed in the sliding groove. The fire extinguishing ammunition magazine is fixedly installed at the bottom end of the irregularly shaped limiting block. The lifting limiting plate is slidably installed on the front end face of the mounting block.

[0011] The irregularly shaped limiting block can be slidably installed in the sliding groove. When the irregularly shaped limiting block is fully inserted into the sliding groove, the lifting limiting plate can move downward. The lifting limiting plate moves to the opening of the sliding groove, fixing the position of the irregularly shaped limiting block. The rotation of the winding roller can wind the lifting rope. The winding and unwinding of the lifting rope drives the hanging mounting block to move vertically. The movement of the hanging mounting block drives the fire extinguishing magazine to move. When extinguishing a fire, the rotating mounting block can rotate and drive the hanging mounting block to rotate, thereby driving the fire extinguishing magazine to rotate.

[0012] Furthermore, the mounting assembly also includes a rotary motor, a winding motor, a rotary fixing block, and a fixing plate. Two of the rotary fixing blocks are fixedly installed on the bottom surface of the UAV body. The rotary mounting block is rotatably connected to the rotary fixing block. The rotary motor is fixedly installed on the side of one rotary fixing block. The drive shaft of the rotary motor passes through the rotary fixing block and is fixedly connected to the rotary mounting block. The winding motor is fixedly installed on the side of the other rotary fixing block. The drive shaft of the winding motor passes through the rotary fixing block and the rotary mounting block and enters the mounting groove to be fixedly connected to the winding roller. The fixing plate is fixedly installed on the bottom surface of the rotary mounting block.

[0013] Furthermore, the mounting assembly also includes a guide cylinder and a guide rope. The guide cylinder is sleeved on the outside of the lifting rope, and the bottom end of the guide cylinder is fixedly connected to the top surface of the lifting plate. The lifting rope passes through the inside of the guide cylinder, and the bottom end of the guide cylinder is fixedly connected to the top surface of the lifting plate. The top surface of the fixed plate has several guide holes. The lifting rope passes through the guide holes and is fixedly connected to the lifting plate. The guide rope is wound around the winding roller, with one end fixedly connected to the winding roller and the other end passing through the guide holes and fixedly connected to the lifting plate.

[0014] Furthermore, the replacement assembly also includes a movable push rod, a return spring, a connecting plate, a guide rod, and a movable connecting rod. The rear end face of the mounting block has a push rod mounting hole. The movable push rod is slidably connected to the push rod mounting hole. The connecting plate is fixedly installed at one end of the movable push rod. The return spring is sleeved on the movable push rod. One end of the return spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the mounting block. The guide rod is fixedly connected to the connecting plate, and the guide rod slides through the mounting block into the sliding groove. The movable connecting rod is fixedly installed on the side of the connecting plate.

[0015] Furthermore, the replacement assembly also includes a horizontal rack, a lifting rack, a rotating gear, a lifting linkage, a lifting mounting plate, and lifting springs. The horizontal rack is slidably mounted on the side of the mounting block, the rotating gear is rotatably mounted on the side of the mounting block, and the lifting mounting plate is slidably mounted on the front end face of the mounting block. One end of the lifting linkage is fixedly connected to the lifting rack, and the other end is fixedly connected to the lifting mounting plate. The horizontal rack is fixedly connected to the moving linkage, and the horizontal rack meshes with the rotating gear. The lifting rack meshes with the rotating gear. A plurality of lifting springs are fixedly mounted on the bottom surface of the lifting mounting plate, and the bottom ends of the lifting springs are fixedly connected to the top surface of the lifting limit plate.

[0016] Furthermore, two irregularly shaped blocks are fixedly installed on the front end face of the mounting block, and an irregularly shaped groove is opened on the top surface of the lifting limit plate, with the irregularly shaped blocks slidingly engaging with the irregularly shaped groove.

[0017] Furthermore, the guide cylinder is divided into upper and lower parts, the upper part being a cone shape made of elastic material and the lower part being a cylinder shape made of metal material.

[0018] Furthermore, the lifting rope and the guide rope have the same winding direction, and their winding and unwinding are synchronized.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Before the drone begins firefighting operations, the irregularly shaped limiting block is slidably installed into the sliding groove. When the block enters the groove, it presses against the moving top rod. This pressure causes the moving top rod to move, which in turn moves the connecting plate. The moving plate, through a connecting rod, moves the horizontal rack, which in turn rotates the rotating gear. This rotation causes the lifting rack to move vertically. The lifting rack, through a lifting connecting rod, moves the lifting mounting plate downwards. The lifting mounting plate then moves the lifting limiting plate downwards, contacting the irregularly shaped limiting block. The lifting spring then compresses, and the irregularly shaped limiting block... When the positioning block is fully inserted into the sliding groove, the irregularly shaped limiting block and the lifting limiting plate disengage. The lifting spring pushes the lifting limiting plate downward to the opening of the sliding groove. The lifting limiting plate and the irregularly shaped block slide together, fixing the position of the irregularly shaped limiting block and fixing the fire extinguishing magazine below the mounting block. Through the sliding engagement between the irregularly shaped limiting block and the sliding groove, as well as the quick locking and unlocking of the lifting limiting plate, the staff can manually complete the disassembly and replacement of the fire extinguishing magazine on the ground without complicated tools or disassembly of the mounting structure, which significantly shortens the standby time of the drone to be put back into fire fighting.

[0021] After the drone has used up all the window-breaking fire extinguishing bombs in its fire extinguishing magazine, it flies over the workers. The winding motor drives the winding roller to rotate, which releases the lifting rope. The released rope moves the lifting plate downward, which in turn moves the mounting block downward, thus moving the fire extinguishing magazine downward. The workers manually push the lifting limit plate upward to release the restriction on the irregularly shaped limit block and remove it from the sliding groove. Another fire extinguishing magazine filled with window-breaking fire extinguishing bombs is then reattached below the mounting block. The winding roller rotates to wind the lifting rope, causing the lifting plate to move upward and reset. The bomb replacement operation is performed after the drone returns to above the workers. The winding roller and lifting rope ensure smooth lifting and lowering of the fire extinguishing magazine, eliminating the need for workers to climb or approach the drone's rotor area, thus avoiding the safety hazards of working at height and contacting moving parts. Furthermore, the drone can complete the bomb replacement without landing, further improving work efficiency. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] As attached Figure 1 To be continued Figure 8 As shown:

[0035] Example 1:

[0036] The present invention provides a window-breaking fire extinguishing bomb dispenser mounted on a drone, comprising a drone body 1, a mounting component 2 and a replacement component 3. The mounting component 2 includes a rotating mounting block 201, a lifting plate 202, a lifting rope 203, a winding roller 204 and a mounting block 205.

[0037] The rotating mounting block 201 is rotatably mounted on the bottom surface of the UAV body 1. The bottom surface of the rotating mounting block 201 is provided with a mounting groove. The winding roller 204 is rotatably mounted in the mounting groove. The lifting rope 203 is wound on the winding roller 204. One end of the lifting rope 203 is fixedly connected to the winding roller 204, and the other end is fixedly connected to the lifting plate 202. The lifting plate 202 is fixedly connected to the mounting block 205.

[0038] Replacement component 3 also includes fire extinguishing magazine 301, irregularly shaped limiting block 302 and lifting limiting plate 303. The front end face of mounting block 205 is provided with a sliding groove. The irregularly shaped limiting block 302 is slidably installed in the sliding groove. The fire extinguishing magazine 301 is fixedly installed at the bottom end of the irregularly shaped limiting block 302. The lifting limiting plate 303 is slidably installed on the front end face of mounting block 205.

[0039] The irregularly shaped limiting block 302 can be slidably installed in the sliding groove. When the irregularly shaped limiting block 302 is fully inserted into the sliding groove, the lifting limiting plate 303 can move downward. The lifting limiting plate 303 moves to the opening of the sliding groove, fixing the position of the irregularly shaped limiting block 302. The rotation of the winding roller 204 can wind the lifting rope 203. The winding and unwinding of the lifting rope 203 drives the hanging mounting block 205 to move vertically. The movement of the hanging mounting block 205 drives the fire extinguishing magazine 301 to move. When extinguishing a fire, the rotating mounting block 201 can rotate and drive the hanging mounting block 205 to rotate, thereby driving the fire extinguishing magazine 301 to rotate.

[0040] Before the drone body 1 begins firefighting, the irregularly shaped limiting block 302 is slidably installed into the sliding groove. When the irregularly shaped limiting block 302 is fully inside the sliding groove, the lifting limiting plate 303 moves downwards to the opening of the sliding groove, fixing the position of the irregularly shaped limiting block 302 and fixing the fire extinguishing magazine 301 below the mounting block 205. After the drone body 1 has used up all the window-breaking fire extinguishing bombs in the fire extinguishing magazine 301, the drone body 1 flies above the operator and rotates around the roller 204 to release the lifting rope 203. The release of the lifting rope 203 causes the lifting plate 202 to move downwards, which in turn causes the mounting block 205 to move downwards, thereby causing the fire extinguishing magazine 301 to move downwards. The operator manually pushes the lifting limiting plate 303 upwards to release the limitation on the irregularly shaped limiting block 302 and remove the irregularly shaped limiting block. 302 is removed from the sliding groove, and another fire extinguishing magazine 301 filled with window-breaking fire extinguishing bombs is re-fixed and mounted below the mounting block 205. The winding roller 204 rotates and winds around the lifting rope 203, causing the lifting plate 202 to move upward and reset. Through the sliding engagement of the irregularly shaped limiting block 302 and the sliding groove, and the quick locking and unlocking of the lifting limiting plate 303, the staff can manually disassemble and replace the fire extinguishing magazine 301 on the ground without complicated tools or disassembling the mounting structure, which significantly shortens the standby time of the drone to be put back into fire fighting. The bomb replacement operation is carried out after the drone returns to above the staff, and the winding roller 204 and the lifting rope 203 are used to achieve the smooth lifting and lowering of the fire extinguishing magazine 301. The staff does not need to climb or approach the drone rotor area, avoiding the safety hazards of high-altitude operation and contact with moving parts. Moreover, the drone can complete the bomb replacement without landing, which further improves work efficiency.

[0041] Example 2:

[0042] This embodiment is basically the same as the previous embodiment, except that the mounting component 2 also includes a rotating motor 206, a winding motor 207, a rotating fixing block 208, and a fixing plate 209. Two rotating fixing blocks 208 are fixedly installed on the bottom surface of the UAV body 1. The rotating mounting block 201 is rotatably connected to the rotating fixing block 208. The rotating motor 206 is fixedly installed on the side of one rotating fixing block 208. The drive shaft of the rotating motor 206 passes through the rotating fixing block 208 and is fixedly connected to the rotating mounting block 201. The winding motor 207 is fixedly installed on the side of the other rotating fixing block 208. The drive shaft of the winding motor 207 passes through the rotating fixing block 208 and the rotating mounting block 201 and enters the mounting groove to be fixedly connected to the winding roller 204. The fixing plate 209 is fixedly installed on the bottom surface of the rotating mounting block 201.

[0043] The mounting assembly 2 also includes a guide cylinder 210 and a guide rope 211. The guide cylinder 210 is sleeved on the outside of the lifting rope 203, and the bottom end of the guide cylinder 210 is fixedly connected to the top surface of the lifting plate 202. The lifting rope 203 passes through the inside of the guide cylinder 210, and the bottom end of the guide cylinder 210 is fixedly connected to the top surface of the lifting plate 202. The top surface of the fixed plate 209 has several guide holes. The lifting rope 203 passes through the guide holes and is fixedly connected to the lifting plate 202. The guide rope 211 is wound around the winding roller 204. One end of the guide rope 211 is fixedly connected to the winding roller 204, and the other end passes through the guide holes and is fixedly connected to the lifting plate 202. The guide cylinder 210 is divided into upper and lower parts. The upper part is a cone made of elastic material, and the lower part is a cylinder made of metal material. The winding direction of the lifting rope 203 and the guide rope 211 is the same, and the winding and unwinding of the two are synchronized.

[0044] In use, the rotating motor 206 drives the rotating mounting block 201 to rotate, the rotating mounting block 201 rotates and drives the mounting block 205 to rotate, thereby driving the fire extinguishing magazine 301 to rotate, and the rotation of the fire extinguishing magazine 301 adjusts the launch angle of the window-breaking fire extinguishing bomb.

[0045] The winding motor 207 drives the winding roller 204 to rotate. The rotation of the winding roller 204 can wind and unwind the lifting rope 203. When the winding roller 204 winds the lifting rope 203, it also winds the guide rope 211 simultaneously. The lifting rope 203 drives the lifting plate 202 to move upward. The guide rope 211 can keep the lifting plate 202 stable. When the guide cylinder 210 enters the guide hole, the winding motor 207 stops working and locks. The upper part of the guide cylinder 210 is tapered, which can reduce the friction between the guide cylinder 210 and the guide hole.

[0046] Example 3:

[0047] This embodiment is basically the same as the previous embodiment, except that the replacement component 3 also includes a movable top rod 304, a return spring 305, a connecting plate 306, a guide rod 307, and a movable connecting rod 308. The rear end face of the mounting block 205 is provided with a top rod mounting hole. The movable top rod 304 is slidably connected to the top rod mounting hole. The connecting plate 306 is fixedly installed on one end of the movable top rod 304. The return spring 305 is sleeved on the movable top rod 304. One end of the return spring 305 is fixedly connected to the connecting plate 306, and the other end is fixedly connected to the mounting block 205. The guide rod 307 is fixedly connected to the connecting plate 306, and the guide rod 307 slides through the mounting block 205 and enters the sliding groove. The movable connecting rod 308 is fixedly installed on the side of the connecting plate 306.

[0048] Replacement component 3 also includes a horizontal rack 309, a lifting rack 310, a rotating gear 311, a lifting connecting rod 312, a lifting mounting plate 313, and a lifting spring 314. The horizontal rack 309 is slidably mounted on the side of the mounting block 205, the rotating gear 311 is rotatably mounted on the side of the mounting block 205, the lifting mounting plate 313 is slidably mounted on the front end face of the mounting block 205, and one end of the lifting connecting rod 312 is fixedly connected to the lifting rack 310, while the other end is fixedly connected to the lifting mounting plate 313. The horizontal rack 309 is fixedly connected to the moving connecting rod 308, and the horizontal rack 309 meshes with the rotating gear 311. The lifting rack 310 meshes with the rotating gear 311. Several lifting springs 314 are fixedly installed on the bottom surface of the lifting mounting plate 313. The bottom end of the lifting springs 314 is fixedly connected to the top surface of the lifting limit plate 303. Two irregular blocks 315 are fixedly installed on the front end face of the mounting block 205. An irregular groove is opened on the top surface of the lifting limit plate 303, and the irregular blocks 315 slide with the irregular groove.

[0049] In use, when the irregularly shaped limiting block 302 enters the sliding groove, it will press against the moving push rod 304. The moving push rod 304 moves under pressure, which in turn moves the connecting plate 306. The movement of the connecting plate 306, through the moving connecting rod 308, drives the horizontal rack 309 to move. The movement of the horizontal rack 309 drives the rotating gear 311 to rotate. The rotation of the rotating gear 311 drives the lifting rack 310 to move vertically. The lifting rack 310, through the lifting connecting rod 312, drives the lifting device... The mounting plate 313 moves downward, and the lifting mounting plate 313 drives the lifting limit plate 303 to move downward and contact the irregularly shaped limit block 302. The lifting spring 314 is compressed. When the irregularly shaped limit block 302 is fully inserted into the sliding groove, the irregularly shaped limit block 302 disengages from the lifting limit plate 303. The lifting spring 314 pushes the lifting limit plate 303 downward to the opening of the sliding groove. The lifting limit plate 303 and the irregularly shaped block 315 slide together, fixing the position of the irregularly shaped limit block 302.

[0050] The sliding and rotating installation methods used in this invention are both clearance fits, and each moving part remains stationary when no external force is applied, and can only move relative to each other when an external force is applied.

[0051] Working principle:

[0052] Before the UAV body 1 performs firefighting operations, the irregularly shaped limiting block 302 is slidably installed into the sliding groove. When the irregularly shaped limiting block 302 enters the sliding groove, it will press against the moving top rod 304. The moving top rod 304 moves under pressure and drives the connecting plate 306 to move. The movement of the connecting plate 306 drives the horizontal rack 309 to move via the moving connecting rod 308. The movement of the horizontal rack 309 drives the rotating gear 311 to rotate. The rotation of the rotating gear 311 drives the lifting rack 310 to move vertically. The lifting rack 310 drives the lifting mounting plate 313 to move downward via the lifting connecting rod 312. The lifting mounting plate 313 drives the lifting limiting plate 303 to move downward and contact the irregularly shaped limiting block 302. When the spring 314 is compressed, and the irregularly shaped limiting block 302 is fully inserted into the sliding groove, the irregularly shaped limiting block 302 disengages from the lifting limiting plate 303. The lifting spring 314 pushes the lifting limiting plate 303 downward to the opening of the sliding groove. The lifting limiting plate 303 and the irregularly shaped block 315 slide together, fixing the position of the irregularly shaped limiting block 302 and fixing the fire extinguishing magazine 301 under the mounting block 205. Through the sliding engagement of the irregularly shaped limiting block 302 and the sliding groove, as well as the quick locking and unlocking of the lifting limiting plate 303, the staff can manually disassemble and replace the fire extinguishing magazine 301 on the ground without complicated tools or disassembling the mounting structure, which significantly shortens the standby time of the drone when it is put back into fire fighting.

[0053] After the drone body 1 has used up all the window-breaking fire extinguishing grenades in the fire extinguishing magazine 301, the drone body 1 flies above the staff. The winding motor 207 drives the winding roller 204 to rotate, and the rotation of the winding roller 204 releases the lifting rope 203. The release of the lifting rope 203 causes the lifting plate 202 to move downward. The lifting plate 202 causes the mounting block 205 to move downward, thereby causing the fire extinguishing magazine 301 to move downward. The staff manually pushes the lifting limit plate 303 upward to release the restriction on the irregularly shaped limit block 302 and removes the irregularly shaped limit block 302. The sliding groove allows another fire extinguishing magazine 301, filled with window-breaking fire extinguishing bombs, to be re-secured and mounted below the mounting block 205. The rotating roller 204 winds around the lifting rope 203, causing the lifting plate 202 to move upward and reset. The bomb changing operation is carried out after the drone returns to above the staff. The rotating roller 204 and the lifting rope 203 are used to achieve the smooth lifting and lowering of the fire extinguishing magazine 301. The staff does not need to climb or approach the drone's rotor area, avoiding the safety hazards of working at height and contacting moving parts. Moreover, the drone can complete the bomb changing without landing, further improving work efficiency.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
