Description

Technical Field

[0001] This invention belongs to the technical fields of airships, low-altitude security, emergency rescue, and long-endurance monitoring platforms, specifically relating to a honeycomb-compartment damage-resistant elliptical streamlined airship safety platform. Background Technology

[0002] Existing airships are mostly single-chamber airbag structures, which are prone to rapid instability and fall if partially damaged, resulting in poor damage resistance and safety. They also have limited functionality, making it difficult to adapt to the needs of various scenarios such as low-altitude security, drone deterrence, and environmental monitoring. Their power supply relies on energy storage batteries, resulting in short battery life and the inability to remain airborne for extended periods. The external module fixing methods are cumbersome, making disassembly and maintenance inconvenient, and they are prone to falling off at high altitudes. Furthermore, the interfaces lack protective design, making them susceptible to wear and damage from wind, sand, and rain at high altitudes, thus limiting their practicality.

[0003] Existing long-endurance airships (such as the "Jimu-1" airship) adopt a single-chamber airbag structure, which requires emergency landing after damage and has poor damage resistance; their payload modules are fixed by mechanical bolts, which cannot be quickly replaced and have weak functional expandability; and they are not equipped with laser-penetrating protection interfaces, making it difficult to cope with the needs of drone interference and intrusion in low-altitude security scenarios, thus limiting their application scenarios. Summary of the Invention Purpose of the invention

[0004] This invention addresses the shortcomings of existing technologies by providing a honeycomb-compartment, damage-resistant, elliptical streamlined floating safety platform. It solves the problems of single-chamber airbags being easily damaged, having short endurance, limited functionality, inconvenient module assembly and disassembly, easy detachment at high altitudes, easily damaged interfaces, limited laser emission, and poor security adaptability. It achieves damage resistance and safety, long endurance, multi-functional adaptability, rapid maintenance, interface protection, and compliance with laser interference regulations. It is suitable for scenarios such as low-altitude security, emergency rescue, environmental monitoring, forest fire prevention, and border patrol. Technical solution

[0005] A honeycomb-compartment damage-resistant elliptical streamlined floating safety platform consists of an elliptical streamlined hull, honeycomb-type independent helium gas compartments, a central independent sealed chamber, a globally distributed magnetic interface matrix, a multi-purpose load module, a high-altitude micro-wind power generation module, and a central control module.

[0006] Elliptical streamlined hull: aerodynamic shape, low wind resistance, stable flight, suitable for long-term aerial operations; Honeycomb independent compartments: multiple sealed and independent units, helium-filled, separated by flame-retardant barrier layers, local damage does not affect the overall buoyancy, and it has extremely strong damage resistance; Central sealed chamber: filled with helium under positive pressure to isolate external moisture / harmful gases and protect electronic equipment; Full-area magnetic matrix: arranged in six directions, with dual fixation of magnetic attraction and mechanical buckles, integrating magnetic coupling power supply and wireless communication, and equipped with a high-transmittance laser penetration protective cover on the outside, which is dustproof, waterproof and damage-proof, with a light transmittance of ≥90% for 800-1550nm lasers; Multi-purpose payload: integrates sensing and compliant laser protection, emits Class 1 low-power laser to interfere with UAV navigation / communication without the risk of blinding; High-altitude micro-wind power generation: Vertical axis wind turbine + reciprocating linkage power generation mechanism, combined with flexible solar thin film array, to form a wind-solar complementary power supply system, providing continuous high-power power supply 24 hours a day to support long flight time; Central control: Fully automatic sensing, identification, and dispatch of laser interference, requiring no continuous manual operation. Working principle

[0007] After the platform takes off, the honeycomb independent compartments provide stable buoyancy; after structural simulation and design, even if a single airbag unit is damaged and the damaged area reaches 15%, the platform can still retain no less than 85% of its original buoyancy, meeting the requirements for safe return to port; the wind turbine components (9) on both sides and the stern of the hull are driven to rotate by the continuous airflow at high altitude, and the rotational motion is converted into reciprocating mechanical motion through the reciprocating linkage power generation component (6), and then the electrical energy is transmitted to the energy storage battery in the central independent sealed compartment (5) through the internal magnetic coupling mechanism (7) and the external magnetic coupling mechanism (8); the flexible solar thin film array (12) on the upper surface of the hull works in conjunction with the wind power generation module to form a wind-solar complementary system, further improving energy stability and meeting the power supply needs in calm weather; the all-area distributed magnetic interface matrix (2) on the surface of the hull can quickly install the multi-purpose load module (11) through magnetic attraction + mechanical limit buckle (13), and the high-transmittance laser outside the interface can penetrate the sealed protective cover (1) to protect the internal structure; the environmental sensing unit 360° The central control module scans the airspace / environment, identifies intruding drones and other risky targets, and dispatches active laser protection units to emit low-power lasers. The lasers penetrate the protective shield and are emitted outwards, interfering with the drone's navigation or communication links. The magnetic interface matrix symmetrically arranged on the sides and top of the hull serves as a repeating arrangement of the front-end interfaces, all supporting the installation of multi-purpose payload modules. The tail of the wind turbine assembly can integrate auxiliary sensing payloads that rotate synchronously with the fan, enabling 360° scanning and monitoring of the airspace behind the platform. If any airbag ruptures, there will only be a single point of leakage, and the platform will maintain buoyancy for safe flight. Faulty payload modules can be quickly disassembled and replaced, making maintenance convenient. Beneficial effects

[0008] Honeycomb independent compartments, damage-resistant and safe: Based on structural simulation design standards, even if a single airbag is damaged by 15%, it can still retain ≥85% buoyancy. Local damage will not cause the whole to fall out of control. The flame-retardant barrier layer prevents the damage from spreading. The safety performance is better than the traditional single-chamber airbag structure. Helium positive pressure sealed chamber: isolates moisture / harmful gases, protects electronic equipment, and extends service life; Full-area magnetic double fixation + laser penetration protective cover: prevents falling at high altitudes, dustproof, waterproof and wear-resistant, with a light transmittance of ≥90% for 800-1550nm lasers, and stable and reliable function; Wind-solar hybrid power supply system: High-altitude wind power + solar power work together to provide power, unaffected by weather, generating electricity continuously 24 hours a day, supporting long flight times of several days to several weeks; Compliant laser protection: Class 1 low-power laser interference, power density ≤1mW / cm², no risk of blindness, meets safety standards; Multifunctional modular design: Quickly switches between sensing and protection modes, adaptable to various scenarios including security, rescue, and monitoring; Fully automated intelligent operation: autonomously sensing, recognizing, and detecting laser interference, lowering the barrier to entry for users; Civilian compliance and controllability: It has no lethal function, is suitable for public service sectors, and ordinary people can apply for authorization.

Detailed Implementation

[0010] The hull adopts an elliptical streamlined structure, with the interior consisting of dozens of independent sealed airbags forming a honeycomb-type independent helium gas compartment group (3). Each airbag is separated by a high-strength flame-retardant barrier layer and is filled with helium. According to the structural simulation design indicators, the damage area of ​​a single airbag is 15%. At that time, the platform buoyancy retention rate is not less than 85%; a central independent sealed chamber (5) is set in the middle of the hull, which is filled with helium and kept under positive pressure, and a central control module and energy storage battery are installed; a wind fan assembly (9) is set at the stern of the hull, which uses the continuous airflow at high altitude to drive the fan to rotate, and converts the rotational motion into reciprocating mechanical motion through the reciprocating linkage power generation assembly (6), and then transmits the electrical energy to the energy storage battery in the central independent sealed chamber (5) through the internal magnetic coupling mechanism (7) and the external magnetic coupling mechanism (8); a flexible solar thin film array (12) is laid on the upper surface of the hull, which works in conjunction with the wind power generation module to form a wind-solar complementary system; a distributed magnetic interface matrix (2) is arranged on the entire surface of the hull, which integrates mechanical magnetic locking, magnetic coupling wireless power supply coil, and wireless communication unit, and is protected against falling off with mechanical limit buckles (13). The interface is fitted with a high-transmittance laser-penetrating sealed protective cover (1) for 800-1550nm. Laser transmittance ≥90%; multi-purpose payload modules (11) are installed as needed. The payload modules include photoelectric cameras, infrared thermal imagers, lidar, and low-power laser jammers. The power density of the laser jammers is ≤1mW / cm², which complies with the IEC 60825-1:2014 Class 1 standard. After the platform takes off, the wind-solar hybrid system continuously supplies power to assist in stabilizing the rotor (4) to improve flight stability. The sensing unit performs full-domain scanning, and the central control module automatically identifies intruding drones and dispatches the laser jammers to emit lasers to penetrate the protective cover and carry out interference. The tail of the wind turbine fan assembly can be integrated with an auxiliary sensing payload that rotates synchronously with the fan to achieve 360° monitoring of the rear airspace. When a local airbag is damaged, the remaining compartments maintain buoyancy and can return safely. The payload module can be quickly disassembled and replaced if it fails, making maintenance convenient.
