Description

Technical Field

[0001] This invention relates to the field of professional fire emergency rescue equipment technology, and more specifically, to an all-terrain tethered flying fire water intake system that can be quickly deployed and adapted to complex terrain. Background Technology

[0002] Currently, professional fire brigades face the challenge of rapidly obtaining water sources when dealing with fires in remote or complex terrains (such as mountains, forests, swamps, and narrow streets). Traditional fire trucks are limited by road accessibility. Existing fire-fighting equipment, such as floating pumps and portable pumps, still heavily rely on manual transport for deployment, which is inefficient in extreme terrains. Furthermore, their water intakes are easily affected by waves, debris, and shallow water near the shore, making it difficult to guarantee the stability and efficiency of water supply.

[0003] The exploration of using drones for firefighting has been limited by battery life and payload, failing to meet the demands of sustained professional firefighting operations with large volumes of water over extended periods. Therefore, the professional firefighting field urgently needs innovative equipment that integrates rapid mobility, stable operation, and continuous water supply capabilities. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an all-terrain tethered aerial firefighting water intake system. This system is designed for professional firefighting operations, adopts a modular integrated scheme, and can be quickly assembled on-site by firefighters. Utilizing a professional tethered power supply, it achieves long-term, stable, suspended water intake, aiming to become a standardized and highly efficient piece of equipment for grassroots fire brigades.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An all-terrain tethered aerial firefighting and water intake system, characterized in that it comprises: A professional-grade inflatable support platform serves as the system's basic float and installation base; Several high-thrust DC brushless ducted fans are symmetrically fixed around the perimeter of the support platform to provide precise and controllable vertical lift. A fire-fighting high-flow-rate, high-lift submersible pump set is fixed to the support platform, and its inlet is equipped with a quick-removable coarse filter protection device. Professional-grade tensile-resistant floating power mooring cable, with a rated voltage compatible with 220V / 380V AC power. One end is electrically connected to the duct fan and submersible pump group through a waterproof quick connector, and the other end is used to connect to a portable fire generator or mains power interface, achieving physical mooring while providing continuous power supply. The fire-fighting high-pressure water hose is sealed to the outlet of the submersible pump set.

[0006] Furthermore, the supporting platform is a high-strength, wear-resistant, fire-fighting inflatable boat with standardized quick-assembly interfaces integrated into the hull.

[0007] Furthermore, there are four ducted fans arranged in a rectangular symmetrical configuration, each equipped with an independent speed controller to support fine-tuning of the system's attitude.

[0008] Furthermore, the coarse filter protection device is a stainless steel perforated protective cover, which effectively intercepts large debris sucked into the water.

[0009] Furthermore, the professional-grade tensile-resistant floating power mooring cable adopts an aramid fiber reinforced core and a wear-resistant polyurethane outer sheath, possessing high tensile strength, floating characteristics, and excellent oil and weather resistance. It can be directly adapted to the 220V / 380V portable generators standardly equipped by grassroots fire brigades, achieving plug-and-play functionality. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The all-terrain tethered aerial firefighting water intake system of this invention mainly encompasses two parts: production and assembly, and firefighting applications, and must comply with safe operating procedures.

[0018] Production and assembly implementation The production of this system follows the principles of "professional standards, modular integration, and rapid assembly." All core components are selected from or procured and integrated in accordance with professional fire-fighting equipment standards.

[0019] Regarding the selection of core components, the load-bearing platform (Figure 1) is an inflatable boat made of professional-grade high-strength wear-resistant PVC mesh material, with a rated load of no less than 150 kg. The hull is pre-installed with standardized quick-connect interfaces. The ducted fan (Figure 2) consists of four industrial-grade high-thrust DC brushless fans, each with a continuous thrust sufficient to meet the system's total lift requirements. The protection rating is no less than IP54, and it is equipped with quick-connect brackets and independent electronic speed controllers. The submersible pump set (Figure 3) is a fire-fighting-specific high-flow submersible pump with a rated flow rate of no less than 50 cubic meters per hour, a head of no less than 60 meters, and an IP68 protection rating. The coarse filter protection device (Figure 5) is a detachable perforated cover made of 304 stainless steel plate, with a mesh size no larger than 8 mm. It is connected to the submersible pump inlet (Figure 4) via quick-release clamps. The power mooring cable (see attached diagram, label 6) is a custom-designed, professional-grade tensile-resistant floating cable with a rated voltage of AC 380V or 220V. The conductor cross-section is no less than 4 square millimeters, and the internal reinforcing core uses aramid fiber to ensure a breaking tensile strength of no less than 20 kN. The outer sheath is made of orange abrasion-resistant polyurethane material, providing permanent buoyancy. Waterproof industrial connectors are pre-installed at both ends of the cable. The control system is integrated into a waterproof control box, responsible for power distribution, signal aggregation, and remote control.

[0020] The system integration and assembly process is as follows: First, unfold the support platform and check its airtightness and the integrity of all quick-connect interfaces. Next, precisely align and lock the four ducted fans onto the reinforced interfaces at the four corners of the support platform using their quick-connect brackets, ensuring the thrust axis of the fans is vertical. Then, connect the power cables and control signal cables of each fan to the central control box. Next, install the coarse filter protection device on the inlet of the submersible pump unit and lock it with quick-release clamps. Then, fix the assembled submersible pump unit into the pre-set "water intake chamber" at the front of the support platform using special clamps, and connect the pump's power cable to the control box. Afterward, connect the core link: securely connect the device end connector of the professional-grade tensile-resistant floating power mooring cable to the main input interface of the control box and tighten the waterproof locking ring; simultaneously, reliably connect the standard fire high-pressure water hose to the outlet of the submersible pump unit through a quick-connect interface. Finally, a systematic test must be conducted before leaving the factory, including airtightness test of the bearing platform, power supply and communication test of the whole system, start-stop and speed regulation test of the duct fan, and jog test of the submersible pump set, to ensure that each module functions normally and all interface connections are reliable.

[0021] Firefighting Practical Application Process The fire protection application of this system revolves around the standardized operating procedures of "rapid response, safe deployment, stable water supply, and flexible withdrawal".

[0022] During the emergency response and rapid transport phase, the system is normally stored in a dedicated transport container and deployed with the main fire truck. Upon arrival at the disaster site, the commander determines the nearest safe and usable water source based on reconnaissance. Subsequently, a three-person combat team (usually including one operator and two support personnel) carries the modular system components and moves on foot to the work site near the water source.

[0023] The rapid on-site assembly and deployment were carried out step by step: First, the support platform was unfolded on the flat beach and quickly inflated; then, four ducted fans were installed at the four corners of the platform, and the submersible pump set with pre-installed filters was installed at the front water intake chamber; next, the device end of the mooring cable was connected, and fire hoses were pre-laid; finally, the assembled system was smoothly pushed into the water, allowing it to float at the predetermined water intake position.

[0024] Next comes the crucial double-point mooring procedure, a core safety operation that must be completed before system startup: The first point is cable mooring and power supply, which involves directly connecting the shore-end connector of the mooring cable to the already started 380V / 220V portable fire generator, while using dedicated ground anchors or ropes to reliably secure the shore-end section of the cable to a sturdy object on the shore (such as a fire truck, trees, or ground stakes); The second point is hose mooring, which involves laying the fire hose to the fire scene water supply point (such as a fire truck pump or distributor), and using hose hooks or simple anchors to further secure the middle section of the hose to prevent the water flow from impacting and dragging the platform.

[0025] After mooring is complete, system startup and continuous water supply operations begin: the operator powers on the system via a waterproof remote control or control box panel. First, start the ducted fan, gradually increasing the total power to smoothly lift the entire system 30 to 50 centimeters above the water surface, achieving a stable hovering state. During this process, the speed of each fan can be fine-tuned via the remote control to counteract wind and waves and maintain the platform's level. Once the system's position is confirmed to be stable, the submersible pump unit is remotely started. At this point, the water, after being filtered by the coarse filter, is pressurized by the pump and continuously delivered to the fire scene via fire hoses. During operation, the pump output power can be remotely adjusted to control the flow rate according to firefighting needs.

[0026] The retrieval after the operation must be carried out according to regulations: the sequence of "stop the pump first, then lower the platform, and finally disconnect the power" must be strictly followed. That is, first, remotely stop the submersible pump unit, then slowly reduce the power of the duct fan to allow the system to smoothly return to the water surface, then turn off the fan and disconnect the generator power supply. Afterwards, release the mooring connections of the hoses and cables, and tow the system back to shore. Finally, perform a quick reverse disassembly: deflate and fold the supporting platform, separate the functional modules, clean the coarse filter protection device, coil up the mooring cables and fire hoses, and after checking that all components are in good condition, load them into the transport container, and then evacuate the site.

[0027] Key safety warnings include: all personnel must wear full personal protective equipment and life jackets; the generator output voltage must be confirmed beforehand to be fully compatible with the rated voltage (380V / 220V) of the mooring cable and system equipment; the system must not be started before a reliable "double-weighted mooring" is completed; operations should be avoided in dangerous waters with thunderstorms, extreme turbulence, or dense underwater obstacles; after each mission, the mooring cable sheath, airbag, coarse filter, and all electrical connectors must be thoroughly inspected and maintained to ensure that the equipment is in good working order.
