Description

Technical Field

[0001] This utility model relates to the field of rescue and fire extinguishing devices, specifically to a self-destructing remote rescue and fire extinguishing device and a remote fire extinguishing system. Background Technology

[0002] In fire rescue operations, how to quickly and effectively extinguish fires is a crucial research topic. For locations with good infrastructure and transportation, fire trucks and fire hydrants can typically be used to extinguish fires. However, for mountainous areas, forests, and some rural farmhouses, chemical plants, oil depots, and other locations where fire trucks cannot reach, drones and helicopters are often used to deliver fire extinguishing materials. However, delivering fire extinguishing materials often requires the aircraft to approach the fire source, resulting in high operating temperatures and potential damage to the aircraft. For example: Patent document (CN216970008U) discloses a drone for firefighting. This type of drone can carry water bags, and upon reaching the fire scene, it pressurizes the water bags using hydraulic cylinders and other mechanisms to spray water for firefighting. However, this requires the drone to be relatively close to the fire source, and the drone is easily damaged by the high temperature. Moreover, the water it carries is sprayed out slowly, and when the fire is large, it often cannot reach the depths of the fire before most of it evaporates, resulting in insufficient firefighting effect.

[0003] Patent document (CN220786121U) discloses a drone-mounted water bag fire extinguishing device. This device is used to carry and throw water bags to precisely extinguish fires by utilizing the drone's hovering advantage. However, because the water bags only release water upon impact or scraping upon landing, most of the water tends to run off along low-lying areas, making it ineffective for extinguishing fires at heights, especially those suspended by tree branches. Furthermore, the throwing mechanism requires an additional power unit, consuming significant portion of the drone's payload capacity and greatly affecting its range. In addition, the small water-breaking area of ​​the thrown water bags leads to considerable water waste and is environmentally unfriendly. Utility Model Content

[0004] To solve at least one of the above technical problems, this utility model provides a self-destructing remote rescue fire extinguishing device and a remote fire extinguishing system.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a self-destructing remote rescue fire extinguishing device, including a mounting frame, a detonation receiver, and a detonation ejector. The sides and bottom of the mounting frame are water-permeable structures, and a water bag is installed inside the mounting frame. The detonation component is installed inside the water bag. The detonation receiver and the detonation ejector are connected via a wireless signal. The detonation receiver is located at the top of the mounting frame and is connected to a detonation wire. The detonation wire extends from the top of the water bag into the water bag and connects to the detonation component.

[0006] The beneficial effects of this utility model are: This invention allows the drone to be mounted on a frame and flown above the fire source to extinguish it, thus avoiding damage caused by high temperatures during operation. The explosive impact of the detonating component bursts the water bag, causing the water to fall rapidly within the blast radius, reducing evaporation and effectively extinguishing suspended fires. Furthermore, the detonator remotely controls the detonator receiver via wireless signal to discharge, igniting the detonating component, making operation convenient. The detonator receiver and detonating component are also lightweight, minimizing the drone's payload capacity and allowing it to carry more water.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, it also includes a clip that snaps onto the top edge of the mounting frame, and the detonator receiver is fixed to the clip.

[0009] It facilitates stable fixation of the detonator receiver, and the detonator receiver is recyclable and can be easily removed and replaced when damaged, making maintenance convenient. In addition, the ruptured water bag can be recycled and disposed of by hanging on the mounting frame, avoiding environmental pollution and demonstrating good environmental performance.

[0010] Furthermore, the mounting frame is a cylindrical cage structure; a support beam is fixed to the top of the mounting frame, a guide tube is fixed to the middle of the support beam, the lower end of the guide tube is sealed to the detonation component, and the detonation wire passes through the guide tube.

[0011] It is easy to manufacture and the gravity is uniform in all directions, which improves the balance of the drone when it is mounted. At the same time, the constraint force on the water bag is the same in all directions, which makes it easy for the water to be evenly distributed in all directions when the detonating component explodes, so that the fire can be extinguished accurately in 360° without leaving any dead corners. The water is isolated by the guide tube to prevent water from entering the detonating component along the detonation wire, which improves the reliability of the detonating component.

[0012] Furthermore, the mounting frame includes a hollowed-out base and a hollowed-out cylinder, with the lower end of the hollowed-out cylinder fixedly connected to the hollowed-out base.

[0013] The perforated base supports the bottom of the water bag, while the perforated cylinder provides even support to the sides, facilitating the uniform dispersion of water from all directions during rupture and reducing blind spots in firefighting. Simultaneously, water can pass through the perforated cylinder and base, resulting in low resistance during dispersion and descent.

[0014] Furthermore, the hollow chassis includes an inner support ring and an outer support ring arranged coaxially and in the same plane. Multiple connecting strips are provided between the inner support ring and the outer support ring. One end of the connecting strip is fixedly connected to the outer side wall of the inner support ring, and the other end of the connecting strip is fixedly connected to the inner side wall of the outer support ring. The lower end of the hollow cylinder is fixedly connected to the outer support ring.

[0015] It has high structural strength and can provide uniform support to the bottom of the water bag; at the same time, the large perforated area reduces the resistance to the falling water flow when the water bag bursts.

[0016] Furthermore, the connecting strips are evenly distributed circumferentially along the inner support ring and extend radially along the support ring; the inner support ring, outer support ring, and connecting strips are all made of magnesium-aluminum alloy.

[0017] By setting the distribution and extension direction of the connecting strips, the physical space occupied is reduced, the hollow area is large, and the weight is small, thus reducing the impact on the drone's carrying capacity.

[0018] Furthermore, the hollow cylinder includes multiple main rings arranged coaxially, with multiple long strips connected between each two adjacent main rings, and the long strips are evenly distributed along the circumference of the main rings.

[0019] It has high structural strength and can provide uniform support to the sides of the water bag; it has a large perforated area, which reduces the resistance when the water bag bursts; and it is lightweight, which reduces the burden on the drone's carrying capacity.

[0020] Furthermore, the detonating component includes a sealed cylinder with one end open, the sealed cylinder being filled with an initiating substance, and a radio frequency ignition fuse block being disposed within the initiating substance; a top cover is detachably connected to the open end of the sealed cylinder, and the detonating wire passes through the top of the top cover and is connected to the radio frequency ignition fuse block.

[0021] With a simple structure and light weight, it detonates the explosive charge by directing the discharge from the detonation receiver to the radio frequency ignition fuse via a detonation wire, making it easy to operate.

[0022] Furthermore, the upper cover is threadedly connected to the sealing cylinder, and an elastic sealing block is provided inside the upper cover. The elastic sealing block is sealed and fitted onto the detonating wire, and the open end of the sealing cylinder abuts against the elastic sealing block.

[0023] By using an elastic sealing block to seal the contact with the detonating wire, water is prevented from entering the detonating material along the detonating wire, ensuring high reliability.

[0024] This utility model also provides a remote fire extinguishing system, including a drone and the above-mentioned self-destructing remote rescue fire extinguishing device. Multiple rigging is fixed on the drone. The multiple rigging is evenly distributed along the circumference of the mounting frame. The lower end of the rigging is fixed with a lifting ring, which is detachably connected to the upper end of the mounting frame.

[0025] The drone is kept away from fire sources, avoiding damage caused by high-temperature operation; it can extinguish suspended fires, achieving rapid and effective fire suppression; the detonator receiver and detonation components are lightweight, allowing it to carry more water; the drone can be carried with a mounting frame for recycling and reuse, and can be quickly reassembled.

[0026] In summary, the self-destructing remote rescue fire extinguishing device and remote fire extinguishing system of this utility model can effectively improve efficiency and achieve the effect of zero casualties among emergency response and rescue personnel. Attached Figure Description

Detailed Implementation

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] This utility model refers to Figure 1-3 .

[0033] This utility model provides a self-destructing remote rescue fire extinguishing device, including a mounting frame 1, a detonation receiver 4, and a detonation ejector. The sides and bottom of the mounting frame 1 are water-permeable structures. A water bag 2 is installed inside the mounting frame 1, and a detonation component 3 is installed inside the water bag 2. The detonation receiver 4 is connected to the detonation ejector via a wireless signal. The detonation receiver 4 is located at the top of the mounting frame 1, and a detonation wire 41 is connected to the detonation receiver 4. The detonation wire 41 extends from the top of the water bag 2 into the water bag 2 and is connected to the detonation component 3.

[0034] principle: During installation, the water bag 2 is placed inside the mounting frame 1 and filled with water. Then, the detonator receiver 4 and the detonating component 3 are installed. The detonator receiver 4 can be fixed to the top of the mounting frame 1. The detonating component 3 has a waterproof and sealed structure, allowing it to be placed inside the water bag 2 and suspended in the water under the pull of a wire, preventing water intrusion. Alternatively, the water bag 2 and the mounting frame 1 can be pre-installed, and the detonator receiver 4 and the detonating component 3 can be installed only when needed.

[0035] When a fire occurs requiring firefighting and rescue, a self-destructing remote rescue fire extinguishing device of this invention is carried by attaching rigging or other mounting tools to a drone or other aircraft. The mounting tools are fixedly connected to the top of the mounting frame 1, allowing the drone to fly with the device. The device is then transported to the fire source. An operator holds a detonator and presses the detonation button. The detonator emits a signal to the detonator receiver 4, which discharges and detonates the detonating component 3. The explosive force of the detonator 3 causes the water bag 2 to burst, causing the water inside to form a water curtain that falls rapidly, effectively extinguishing the fire below. Preferably, multiple drones carrying multiple self-destructing remote rescue fire extinguishing devices can be used in a swarm operation, concentrating the water within a predetermined area and spraying it quickly. The high density of the falling water prevents excessive evaporation, thus rapidly extinguishing the fire.

[0036] Preferably, the detonator receiver 4 can be a radio frequency (RF) fuse device specifically designed for RF ignition fuses, such as arc pulse generators, wireless remote electronic controls for fireworks, wireless remote controls for lighters, tungsten filament igniters, and long-distance ignition controllers. These products all have a transmitter and a receiver; the transmitter is a remote control, i.e., the aforementioned detonator; the receiver is an RF fuse device, i.e., the aforementioned detonator receiver 4. Correspondingly, the detonating component 3 contains an RF ignition fuse block 13. When the detonation button of the aforementioned detonator (remote control) is pressed, the detonator receiver 4 receives a signal and discharges, triggering the RF ignition fuse block 13. The RF ignition fuse block 13 then detonates the explosive material inside the detonating component 3, completing the detonation. The wireless triggering detonation method of the aforementioned RF ignition fuse block 13 is existing technology. The explosive material is a civilian-use explosive.

[0037] Note: The size of the drone can be selected based on the water capacity of the water bag 2. For example, when using a transparent plastic water bag 2 with a capacity of 75-250 kg and a thickness of 1.5 mm, a 12-legged drone can be used. It is mounted on a steel cable with a diameter of 8.5 mm-15.2 mm (selected according to the water bag volume) and a length of 70 cm, connected to the hanging ring at the upper end of the mounting frame 1. The mounting frame 1 can be 45 cm in diameter, 85 cm in diameter, and 1 meter in height. Meanwhile, the explosive charge in the detonating component 3 can be 8 grams (75 kg water) to 20 grams (250 kg water) of fire extinguishing explosive. After detonation, the water curtain effectively covers an area of ​​approximately 80 square meters (75 kg water) to 600 square meters (250 kg water), achieving the purpose of extinguishing the fire. The explosive force will not damage the mounting frame 1. The components used are optimized and adjusted according to the water volume and weight. Furthermore, multiple drones can fly within an area of ​​80-600 square meters, meeting the requirements for swarm operations.

[0038] Preferably, multiple fixing plates 18 are fixed to the upper end of the mounting frame 1. The multiple fixing plates 18 are evenly distributed along the circumference of the mounting frame 1, and the fixing plates 18 are used to connect the lifting rings.

[0039] In summary, by adopting this utility model, when a fire occurs requiring firefighting and rescue, the drone can be carried by the mounting frame 1 to fly above the fire source to extinguish the fire, thus avoiding damage caused by the high temperature of the drone during operation. The explosive impact of the detonating component 3 bursts the water bag 2, causing the water carried to form a water curtain and fall within the explosion range in a short time, reducing water evaporation and extinguishing suspended fire sources, achieving rapid and effective fire extinguishing. In addition, the detonator remotely controls the detonator receiver 4 to discharge via wireless signal, thereby detonating the detonating component 3, which is convenient to operate. Furthermore, the detonator receiver 4 and the detonating component 3 are small and lightweight, avoiding excessive consumption of the drone's load-bearing capacity and allowing it to carry more water.

[0040] Furthermore, it also includes a buckle 5, which is snapped onto the top edge of the mounting frame 1, and the detonator receiver 4 is fixed to the buckle 5; a support beam 16 is fixed to the top of the mounting frame 1, and a guide tube 17 is fixed to the middle of the support beam 16. The lower end of the guide tube 17 is sealed to the detonating component 3, and the detonating wire 41 passes through the guide tube 17.

[0041] The detonator receiver 4 is easy to fix stably. At the same time, the detonator receiver 4 is recyclable and can be easily removed and replaced when damaged, making maintenance convenient. In addition, the water bag 2 that explodes can be recycled and disposed of by hanging on the mounting frame 1, avoiding environmental pollution and having good environmental performance. Water is isolated by the guide tube 17 to prevent water from entering the detonating component 3 along the detonation wire 41, which improves the reliability of the detonating component 3.

[0042] Furthermore, such as Figure 1-2As shown: The mounting frame 1 is a cylindrical cage structure.

[0043] It is easy to manufacture and the gravity is uniform in all directions, which improves the balance when the drone is mounted. At the same time, the constraint force on the water bag 2 is the same in all directions, which makes it easy for the water to be evenly distributed from all directions when the detonating component 3 explodes, so that it can extinguish fires accurately in 360° without leaving any dead corners.

[0044] Furthermore, the mounting frame 1 includes a hollowed-out base and a hollowed-out cylinder, with the lower end of the hollowed-out cylinder fixedly connected to the hollowed-out base.

[0045] Preferably, the lower end of the hollow cylinder is welded to the hollow base plate.

[0046] The perforated base supports the bottom of water bag 2, while the perforated cylinder provides even support to the sides of water bag 2, facilitating the uniform dispersion of water from all directions during explosion and reducing blind spots in firefighting. Simultaneously, water can pass through the perforated cylinder and base, dispersing and falling with minimal resistance.

[0047] Furthermore, the hollow chassis includes an inner support ring 6 and an outer support ring 7 arranged coaxially and in the same plane. Multiple connecting strips 8 are provided between the inner support ring 6 and the outer support ring 7. One end of the connecting strip 8 is fixedly connected to the outer side wall of the inner support ring 6, and the other end of the connecting strip 8 is fixedly connected to the inner side wall of the outer support ring 7. The lower end of the hollow cylinder is fixedly connected to the outer support ring 7.

[0048] Preferably, the two ends of the connecting strip 8 are fixedly connected to the inner support ring 6 and the outer support ring 7 by a combination of welding and riveting. This enhances the strength of the water frame ribs during large-capacity water bag operation and ensures safety and reliability during high-altitude transport.

[0049] It has high structural strength and can provide uniform support for the bottom of water bag 2; at the same time, the large perforated area reduces the resistance to the falling water flow when water bag 2 bursts.

[0050] Furthermore, the connecting strip 8 is evenly distributed along the circumference of the inner support ring 6 and extends radially along the support ring; the inner support ring 6, the outer support ring 7 and the connecting strip 8 are all made of magnesium-aluminum alloy.

[0051] Preferably, there are eight connecting strips 8. In addition, the entire mounting frame 1 can be made of stainless steel.

[0052] By setting the distribution pattern and extension direction of the connecting strips 8, the physical space occupied is reduced, the hollow area is large, and the weight is small, thus reducing the impact on the carrying capacity of the drone.

[0053] Furthermore, the hollow cylinder includes multiple main rings 9 arranged coaxially, and multiple long strips 10 are connected between every two adjacent main rings 9. The long strips 10 are evenly distributed along the circumference of the main rings 9.

[0054] Preferably, the main ring 9 and the long strip 10 are fixedly connected by a combination of welding and riveting. This enhances the strength of the water frame ribs during large-capacity water bag operation and ensures safety and reliability during high-altitude transport.

[0055] It has high structural strength and can provide uniform support to the sides of the water bag 2; it has a large hollow area, so the resistance is small when the water bag 2 bursts; and it is lightweight, which reduces the burden on the drone's carrying capacity.

[0056] Furthermore, such as Figure 3 As shown: The detonating component 3 includes a sealed cylinder 11 with one end open, the sealed cylinder 11 is filled with a detonating substance 12, and the detonating substance 12 is provided with a radio frequency ignition fuse block 13; the open end of the sealed cylinder 11 is detachably connected to a top cover 14, and the detonating wire 41 passes through the top of the top cover 14 and is connected to the radio frequency ignition fuse block 13.

[0057] Preferably, the detonating substance 12 is a special explosive for fire extinguishing bombs.

[0058] With a simple structure and light weight, the discharge from the detonator receiver 4 is led to the radio frequency ignition fuse block 13 through the detonation wire 41 to achieve detonation, which is easy to operate.

[0059] Furthermore, the upper cover 14 is threadedly connected to the sealing cylinder 11, and an elastic sealing block 15 is also provided inside the upper cover 14. The elastic sealing block 15 is sealed and fitted onto the detonating wire 41, and the open end of the sealing cylinder 11 abuts against the elastic sealing block 15.

[0060] The elastic sealing block 15 is in sealed contact with the detonating wire 41, which prevents water from entering the detonating material 12 along the detonating wire 41, thus ensuring high reliability.

[0061] Preferably, both the sealing cylinder 11 and the upper cover 14 are made of nylon. The elastic sealing block 15 can be made of rubber or other materials. In addition, sealant can be filled around the detonating wire 41 at the through hole of the upper cover 14 to achieve sealing of the detonating wire 41.

[0062] It is lightweight, has good sealing properties, and is easy to explode.

[0063] This utility model also provides a remote fire extinguishing system, including a drone and the above-mentioned self-destructing remote rescue fire extinguishing device. Multiple rigging is fixed on the drone. The multiple rigging is evenly distributed along the circumference of the mounting frame 1. The lower end of the rigging is fixed with a lifting ring, which is detachably connected to the upper end of the mounting frame 1.

[0064] The drone is kept away from fire sources, avoiding damage caused by high-temperature operation; it can extinguish suspended fire sources, achieving rapid and effective fire suppression; the detonator receiver 4 and detonating component 3 are lightweight and can carry more water; the drone can be carried with the mounting frame 1 for recycling and reuse, and can be quickly reassembled.

[0065] In summary, the self-destructing remote rescue fire extinguishing device and remote fire extinguishing system of this utility model can effectively improve efficiency and achieve the effect of zero casualties among emergency response and rescue personnel.
