Description

Technical Field

[0001] This invention relates to the field of drone accessory technology, and in particular to a fire hose anti-detachment mounting device for fire-fighting drones. Background Technology

[0002] With the rapid development of drone technology, firefighting drones, with their advantages of maneuverability, flexibility and rapid response, are widely used in firefighting operations in complex scenarios such as high-rise buildings, forests and chemical industrial parks.

[0003] The core operating component of firefighting drones is the fire hose, and its mounting stability directly determines the safety and effectiveness of firefighting operations.

[0004] Currently, most existing fire-fighting drones use rigid connection structures for their water nozzles. However, the instantaneous recoil force generated when the water nozzle sprays water is directly transmitted to the drone's fuselage. This can easily cause the drone to lose its flight attitude and shake violently, affecting the accuracy of fire-fighting aiming. It can also cause long-term damage to the drone's fuselage structure and shorten the equipment's service life. Moreover, existing devices mostly use bolt fastening and snap-fit ​​fixing methods, with fixed clamping force that cannot be adaptively adjusted. Under the repeated impact of recoil force, problems such as loose bolts and deformed snaps can easily occur, leading to water nozzle displacement or even detachment, causing safety accidents.

[0005] Especially in high-pressure water jet fire extinguishing scenarios, the recoil force of the water gun increases significantly, making the above problems more prominent. Although some existing technologies have attempted to add buffer pads or strengthen the clamping structure, they have failed to achieve linkage and adaptation between buffering and clamping. Either the buffering effect is limited, or the clamping force cannot be adaptively adjusted with changes in recoil force. It is difficult to simultaneously solve the two core requirements of buffering protection and anti-drop clamping, which restricts the safety and reliability of fire-fighting drone fire extinguishing operations. Summary of the Invention

[0006] This invention provides a fire hose anti-detachment mounting device for fire-fighting drones. This invention enhances the buffer protection against the recoil force of the water hose spray, reduces the impact of the recoil force on the drone body, and achieves adaptive clamping and fixing according to the recoil force, thus preventing the water hose from loosening or falling off.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a fire hose anti-detachment mounting device for fire-fighting drones, comprising: a fuselage load-bearing beam, a nozzle, a mounting slide, a bearing base, and a buffer pressure linkage mechanism; the buffer pressure linkage mechanism is located on the side of the mounting slide away from the nozzle, and is used to absorb the recoil force generated when the nozzle sprays water, and simultaneously realize adaptive secondary clamping of the mounting slide; the buffer pressure linkage mechanism includes a first polyurethane buffer pad, a pressure plate, a buffer spring, two pressure rods, two first piston plates, two hydraulic cylinders, two high-pressure hydraulic oil pipes, two sleeves, two second piston plates, two round rods, two return springs, and two clamping plates.

[0008] As a further improvement of the present invention: a first fixing plate is fixedly provided at the bottom of the bearing base, the side of the first polyurethane buffer pad away from the contact plate is fixedly connected to the pressure plate, one end of the two pressure rods is fixedly provided on the side of the pressure plate away from the first polyurethane buffer pad, and the other end is fixedly connected to the two first piston plates respectively, and the buffer spring is fixedly provided on the opposite side of the pressure plate and the first fixing plate.

[0009] As a further improvement of the present invention: the two first piston plates are respectively sealed and embedded in the inner walls of the two hydraulic cylinders, and the two hydraulic cylinders are respectively fixedly disposed on both sides of the first fixing plate.

[0010] As a further improvement of the present invention: the bottom of the bearing base near both sides is fixedly provided with a second fixing plate, the opposite sides of the two second fixing plates are respectively fixed to the opposite ends of the two sleeves, and the two second piston plates are respectively sealed and embedded in the inner wall of the two sleeves.

[0011] As a further improvement of the present invention: one end of each of the two second piston plates is fixedly connected to one end of each of the two round rods, and the two return springs are respectively movably sleeved on the outer surface of the two round rods, with the ends away from the second piston plates abutting against the open ends of the two sleeves.

[0012] As a further improvement of the present invention: the two hydraulic cylinders are respectively connected to the two sleeves through high-pressure hydraulic oil pipes, the ends of the two round rods away from the second piston plate are respectively fixedly connected to the two clamping plates, and the sides of the two clamping plates near the mounting slide are respectively fixedly provided with nitrile rubber vibration damping pads and polyurethane anti-slip pads, and the outer surfaces of the two hydraulic cylinders are each equipped with a filling pipe with a sealing plug.

[0013] As a further improvement of the present invention: the bearing base is fixedly installed on the lower side of the body load-bearing beam, and two slide rails are fixedly installed parallel and symmetrically on the lower surface of the bearing base. The two slide rails have guide channels on their inner sides that are adapted to the sliding of the mounting slide, and the inner sides of the two slide rails are provided with limit grooves.

[0014] As a further improvement of the present invention: a limiting plate is movably embedded in the inner wall of the two limiting grooves, and a slot is opened on the side of the limiting plate near the bearing base, and a second polyurethane buffer pad is fixedly provided on the inner wall of the slot.

[0015] As a further improvement of the present invention: the gun head and the mounting slide are integrally formed, the mounting slide is slidably embedded in the guide channel of the two slide rails, and a contact plate is fixedly provided on the side of the mounting slide away from the limiting plate.

[0016] As a further improvement of the present invention: a pull plate is fixedly provided on one side of the limiting plate, and the side of the mounting slide away from the contact plate is tightly fitted with the second polyurethane buffer pad.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. This invention uses a first polyurethane buffer pad and a buffer spring to form a two-stage buffer structure, which, together with the auxiliary buffer of a second polyurethane buffer pad, forms a multi-layered recoil force absorption system. When the gun nozzle generates recoil force, the first polyurethane buffer pad first absorbs the peak recoil force through elastic deformation, weakening the instantaneous impact. The remaining recoil force drives the pressure plate to compress the buffer spring, and the spring deformation further absorbs the impact energy, realizing the graded attenuation of recoil force, reducing the transmission efficiency of recoil force, and effectively preventing the recoil force from being directly transmitted to the UAV fuselage. This ensures the stability of the UAV's flight attitude, improves the accuracy of fire extinguishing aiming, reduces long-term damage to the fuselage structure from recoil force, and extends the service life of the equipment.

[0018] 2. This invention converts the recoil force into clamping power through a buffer hydraulic linkage mechanism, achieving adaptive matching between the clamping force and the recoil force. The recoil force drives the pressure rod and the first piston plate to move, causing the hydraulic oil in the hydraulic cylinder to form high pressure. This high pressure is transmitted to the sleeve through the high-pressure hydraulic oil pipe, pushing the second piston plate and the round rod to move the clamping plate closer to the mounting slide and clamp it. The greater the recoil force, the stronger the clamping force generated by the hydraulic system. It can respond to the recoil force impact under different injection pressures in real time and solve the loosening problem caused by the fixed clamping force of the existing device.

[0019] 2. This device does not require additional drive components such as motors and cylinders. It directly utilizes the recoil force of the nozzle spray to achieve buffering and clamping simultaneously. This simplifies the structure, reduces the load on the UAV, and improves operational reliability. The recoil force is both the load that needs to be buffered and the power source for the clamping action, enabling precise linkage between the buffering and clamping actions and avoiding the poor compatibility problem caused by the two working independently.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-8 This invention provides a fire hose anti-detachment mounting device for fire-fighting drones, comprising: a fuselage load-bearing beam 1, a nozzle 101, a mounting slide 102, a support base 103, and a buffer pressure linkage mechanism; the buffer pressure linkage mechanism is located on the side of the mounting slide 102 away from the nozzle 101, and is used to absorb the recoil force generated when the nozzle 101 sprays water, and simultaneously realize adaptive secondary clamping of the mounting slide 102; the buffer pressure linkage mechanism includes a first polyurethane buffer pad 205, a pressure plate 204, a buffer spring 206, two pressure rods 203, two first piston plates 202, two hydraulic cylinders 201, two high-pressure hydraulic oil pipes 308, two sleeves 301, two second piston plates 302, two round rods 303, two return springs 307, and two clamping plates 304.

[0031] In use, first pull out the limiting plate 402 through the pull plate 403, slide the mounting slide 102, which is integrally formed with the gun head 101, along the guide channel of the slide rail 4, and then insert the limiting plate 402 to make the mounting slide 102 fit with the second polyurethane buffer pad 405 to complete the pre-positioning. After the UAV carrying the device arrives at the working area, the recoil force generated by the water jet from the gun head 101 pushes the mounting slide 102 to squeeze the buffer pressure linkage mechanism, so as to realize the recoil force absorption and adaptive secondary clamping.

[0032] Please see Figures 1 to 8 In one embodiment, a first fixing plate 2 is fixedly provided at the bottom of the support base 103, a first polyurethane buffer pad 205 is fixedly connected to the pressure plate 204 on the side away from the contact plate 208, one end of the two pressure rods 203 is fixedly provided on the side of the pressure plate 204 away from the first polyurethane buffer pad 205, and the other end is fixedly connected to the two first piston plates 202 respectively, and a buffer spring 206 is fixedly provided on the opposite side of the pressure plate 204 and the first fixing plate 2.

[0033] Specifically, when the mounting slide 102 is subjected to a recoil force, the contact plate 208 on one side will squeeze the first polyurethane buffer pad 205, which in turn pushes the pressure plate 204 to compress the buffer spring 206, and at the same time drives the two pressure rods 203 to move synchronously. The pressure rods 203 drive the first piston plate 202 to slide in the hydraulic cylinder 201, providing power for subsequent hydraulic transmission and realizing the linkage triggering of buffering and clamping.

[0034] Please see Figures 1 to 8 In one embodiment, two first piston plates 202 are respectively sealed and embedded in the inner walls of two hydraulic cylinders 201. The two hydraulic cylinders 201 are respectively fixed on both sides of the first fixing plate 2. O-ring seals are installed between the first piston plates 202 and the inner walls of the hydraulic cylinders 201, which can effectively prevent hydraulic oil leakage under high pressure conditions. The symmetrical fixed installation method can ensure the coaxiality of the two pressure rods 203 when pushing the first piston plates 202 to move, and avoid piston plate jamming or hydraulic cylinder wear due to force offset.

[0035] Please see Figures 1 to 8 In one embodiment, a second fixing plate 3 is fixedly provided on the bottom of the support base 103 near both sides. The opposite sides of the two second fixing plates 3 are respectively fixed to the opposite ends of the two sleeves 301, and the two second piston plates 302 are respectively sealed and embedded in the inner wall of the two sleeves 301.

[0036] Please see Figures 1 to 8 In one embodiment, one end of each of the two second piston plates 302 is fixedly connected to one end of each of the two round rods 303. Two return springs 307 are respectively movably sleeved on the outer surface of the two round rods 303 and the ends away from the second piston plates 302 respectively abut against the open ends of the two sleeves 301. The two return springs 307 can quickly drive the second piston plates 302 and the round rods 303 to reset after the water spraying operation is completed.

[0037] Please see Figures 1 to 8 In one embodiment, two hydraulic cylinders 201 are connected to two sleeves 301 via high-pressure hydraulic oil pipes 308. The ends of two round rods 303 away from the second piston plate 302 are fixedly connected to two clamping plates 304. On the side of the two clamping plates 304 near the mounting slide 102, nitrile rubber vibration damping pads 305 and polyurethane anti-slip pads 306 are fixedly installed in sequence. The nitrile rubber vibration damping pads 305 are used to absorb the high-frequency vibration during nozzle spraying, and the polyurethane anti-slip pads 306 are used to increase the friction between the clamping plates 304 and the mounting slide 102. The outer surfaces of the two hydraulic cylinders 201 are equipped with oil filling pipes 207 with sealing plugs. The oil filling pipes 207 facilitate the subsequent filling and replacement of hydraulic oil, and the sealing plugs equipped with the oil filling pipes 207 are made of high-temperature resistant rubber material, which can maintain good sealing performance in the high-temperature environment of fire fighting operations, preventing hydraulic oil leakage or water vapor from entering the hydraulic system and affecting its normal operation.

[0038] Please see Figures 1 to 8In one embodiment, the support base 103 is fixedly installed on the lower side of the body load-bearing beam 1. Two slide rails 4 are fixedly installed parallel and symmetrically on the lower surface of the support base 103. The two slide rails 4 have guide channels on their inner sides that are adapted to the sliding of the mounting slide 102. The inner sides of the two slide rails 4 are provided with limit grooves 401. The guide channels are used to limit the movement direction of the mounting slide 102 and ensure that it can only slide in the direction of the recoil force.

[0039] Please see Figures 1 to 8 In one embodiment, a limiting plate 402 is movably embedded in the inner wall of the two limiting grooves 401. A slot 404 is opened on the side of the limiting plate 402 near the bearing base 103. A second polyurethane buffer pad 405 is fixedly provided on the inner wall of the slot 404. The second polyurethane buffer pad 405 can buffer when the mounting slide 102 abuts, avoiding hard contact that could damage the components.

[0040] Please see Figures 1 to 8 In one embodiment, the gun head 101 and the mounting slide 102 are integrally formed. The mounting slide 102 is slidably embedded in the guide channel of the two slide rails 4, and a contact plate 208 is fixedly provided on the side of the mounting slide 102 away from the limiting plate 402. During installation, the upper side of the mounting slide 102 can be aligned with the guide channel of the two slide rails 4 and slid into the pressure plate 204 along the length direction of the slide rails 4.

[0041] Please see Figures 1 to 8 In one embodiment, a pull plate 403 is fixedly provided on one side of the limiting plate 402, and the side of the mounting slide 102 away from the contact plate 208 is tightly attached to the second polyurethane buffer pad 405. The limiting plate 402 is pulled by the pull plate 403 to pull it out from the limiting groove 401 of the slide rail 4, thereby releasing the travel restriction on the gun head 101.

[0042] The anti-detachment mounting device for drone fire hoses disclosed in this embodiment is based on a hydraulic linkage mechanism driven by the recoil force of the nozzle 101, achieving dual protection of buffering energy absorption and adaptive secondary clamping. Its specific working principle consists of three core processes: installation, spraying operation, and water outage reset, detailed below: Installation Phase: First, fix the support base 103 to the lower side of the machine body load-bearing beam 1, ensuring that the connection surface between the support base 103 and the machine body load-bearing beam 1 is tightly fitted, providing a stable installation benchmark for all subsequent components. At the same time, fix the two slide rails 4 parallel and symmetrically to the lower surface of the support base 103. The inner sides of the two slide rails 4 are each provided with guide channels to accommodate the sliding of the gun head 101. The mounting slide 102 is integrally formed with the gun head 101. Align the upper side of the mounting slide 102 with the guide channels of the two slide rails 4, and slide it along the length of the slide rails 4 towards the side of the pressure plate 204. During this process, the contact plate 208, which is fixedly connected to the mounting slide 102, first contacts and slightly compresses the first polyurethane buffer pad 205, causing the pressure plate 204 to move slightly backward. This causes the buffer spring 206 to undergo elastic deformation. At this time, the limiting plate 402 is inserted into the limiting groove 401 of the two slide rails 4. The limiting plate 402 limits the sliding stroke of the gun head 101 along the slide rail 4. The mounting slide 102 is released, and the elastic force of the buffer spring 206 will push the contact plate 208 forward. The side of the mounting slide 102 away from the contact plate 208 is inserted into the slot 404 opened by the limiting plate 402 and is in close contact with the second polyurethane buffer pad 405 connected inside the slot 404, so as to realize the bidirectional pre-positioning of the gun head 101 and reduce the shaking in the non-operation state. High temperature resistant and anti-wear hydraulic oil is injected into the two hydraulic cylinders 201 through the oil filling pipe 207 on the two hydraulic cylinders 201. After the oil filling is completed, the oil filling pipe 207 is sealed. During the spraying operation phase: When the nozzle 101 begins spraying water for fire extinguishing, the recoil force generated by the high-pressure water jet will first push the nozzle 101 to drive the mounting slide 102 to slide backward along the two slide rails 4, that is, towards the two hydraulic cylinders 201. During this process, the buffering action starts before the clamping action, but they are not synchronized. Specifically, the buffering energy absorption is as follows: when the mounting slide 102 slides backward, the contact plate 208 on one side simultaneously squeezes the first polyurethane buffer pad 205, using the elastic deformation of the buffer pad to absorb part of the peak recoil force, and the remaining thrust is transferred to the pressure plate. 204 compresses and presses the buffer spring 206, further absorbing impact energy through spring deformation to achieve secondary buffering. During the buffering process, the mounting slide 102 will continuously move backward for a certain stroke. Specifically, the secondary clamping is as follows: as the mounting slide 102 moves backward, the pressure plate 204 moves backward synchronously, driving the two symmetrical pressure rods 203 fixed to it to move synchronously. The pressure rods 203 push the first piston plate 202 to move axially inside the hydraulic cylinder 201. Since the hydraulic cylinder 201 is sealed and filled with hydraulic oil, the compression action of the first piston plate 202 causes the hydraulic... The hydraulic oil pressure inside cylinder 201 increases sharply, completing the energy conversion from mechanical thrust to hydraulic pressure. The high-pressure hydraulic oil is rapidly transmitted through high-pressure hydraulic oil pipe 308 to the interior of the two sleeves 301, pushing the second piston plates 302 inside sleeves 301 to move relative to each other. The second piston plates 302 drive the round rod 303 to move synchronously, and the round rod 303 pushes the clamping plate 304 towards the mounting slide 102 until the polyurethane anti-slip pad 306 inside the clamping plate 304 is tightly fitted with both sides of the mounting slide 102, completing the secondary... When clamped and the recoil force continues to act, the gun head 101 will continuously push the mounting slide 102 backward to apply a thrust, so that the squeezing force of the first piston plate 202 on the hydraulic oil continues to exist, the hydraulic pressure in the sleeve 301 remains stable, and thus the clamping force of the clamping plate 304 on the mounting slide 102 remains constant. At the same time, the nitrile rubber vibration damping pad 305 absorbs the high-frequency vibration when the gun head 101 sprays, and the polyurethane anti-slip pad 306 increases the static friction between the clamping plate 304 and the mounting slide 102, avoiding relative sliding and achieving reliable fixation of the gun head 101. Water shut-off and reset phase: After the fire extinguishing operation is completed and the nozzle 101 stops spraying water, the recoil force disappears, the buffer spring 206 releases its elastic potential energy, pushing the pressure plate 204 forward. The pressure plate 204 drives the pressure rod 203 and the first piston plate 202 to move in the opposite direction, and the hydraulic pressure in the hydraulic cylinder 201 decreases accordingly. The high-pressure hydraulic oil flows back to the inside of the hydraulic cylinder 201 through the high-pressure hydraulic oil pipe 308. After the hydraulic pressure in the sleeve 301 decreases, the elastic potential energy of the reset spring 307 begins to be released, pushing the second piston plate 302 to move in the opposite direction, that is, the two second piston plates 302 move away from each other. The second piston plate 302 drives the round rod 303 and the clamping plate 304 to move synchronously. The clamping plate 304 separates from the mounting slide 102, the secondary clamping state is released, and the pressure plate 206... 4. When moving forward, the first polyurethane buffer pad 205 and the contact plate 208 drive the gun head 101 to slide forward along the slide rail 4 until the gun head 101 returns to the initial installation position. At this time, the mounting slide 102 will be inserted into the preset slot 404 of the slide rail 4, and the second polyurethane buffer pad 405 will contact the mounting slide 102, which can effectively reduce the impact force of the mounting slide 102 on the limiting plate 402 during the reset process and avoid rigid collision causing component wear. If the gun head 101 needs to be removed, the limiting plate 402 can be pulled by the pull plate 403 to pull it out from the limiting slot 401 of the slide rail 4, releasing the travel restriction on the gun head 101. At this time, the combination of the gun head 101 and the mounting slide 102 can be slid along the slide rail 4 to remove it from the slide rail 4 and complete the disassembly.

[0043] In summary, this invention uses the recoil force of the nozzle 101 as a power source, and can simultaneously achieve buffering and energy absorption and adaptive secondary clamping without the need for additional drive components. It can also automatically reset after water supply is interrupted. The overall structure is compact and reliable in operation, and it meets the lightweight and automation requirements of UAV firefighting operations.

[0044] Compared to existing technologies, most drone fire hose mounting devices use rigid snap-fit ​​structures, which cannot cope with the instantaneous recoil force when the nozzle is spraying water, making them prone to loosening and falling off. Furthermore, they lack a buffer function, and the recoil force is directly transmitted to the drone fuselage, affecting flight stability. This invention integrates buffering and energy absorption with a secondary clamping function through a recoil force-linked hydraulic mechanism. It achieves adaptive protection without additional drive components, solving the problem of loosening caused by rigid fixation and avoiding the impact of recoil force being directly transmitted to the fuselage on flight stability, thereby improving operational efficiency.
