Description

Technical Field

[0001] The present invention relates to the technical field of wind wheel structures, and in particular to a lotus-shaped wind wheel structure with a special structure and multiple functions and suitable for multiple protection scenarios. Background Art

[0002] In the field of modern military and important facility protection, the threat from low-altitude weapons such as suicide drones, cruise missiles, rockets and suicide unmanned boats is becoming increasingly severe. The existing protection system has obvious defects, which are mainly reflected in the following aspects: limited protection effectiveness, it is difficult to effectively intercept complex and changeable incoming targets; lack of flexible adaptability to different application scenarios, unable to meet the diversified protection needs of individual combat, combat vehicles, large facilities, etc.; low energy utilization efficiency, unable to achieve effective energy replenishment; information isolation between various protection devices, it is difficult to form an efficient collaborative protection system. Therefore, a new type of protection device is urgently needed to solve these problems in order to enhance the protection capabilities of modern military and important facilities. Summary of the invention

[0003] The object of the present invention is to provide a lotus-shaped wind wheel structure to solve the above-mentioned problems existing in the existing protection system.

[0004] 1. Wind wheel structural design: The wind wheel of the present invention is designed as a unique lotus-shaped umbrella, which is composed of multiple layers of soft, high-strength, and high-toughness umbrella-shaped blades. This structural design is inspired by the shape of the lotus and has good aerodynamic performance. Each layer of blades is spaced a certain distance apart, the center layer is the highest layer, and the diameter range of each layer of blades increases layer by layer from the center layer to the outer layer. The diameter change of each layer conforms to the specific proportional relationship obtained through computer simulation design analysis (generally the diameter of the center layer is 20-30 cm, and each layer increases by 15-20 cm toward the outer layer). This proportional relationship ensures that the wind wheel can efficiently convert wind energy into mechanical energy under different wind conditions, thereby providing powerful power support for intercepting incoming low-altitude weapons. In a breeze environment, the smaller diameter center layer blades can start quickly. As the wind increases, the outer layer blades with gradually increasing diameters play a role in turn, ensuring the stable operation and high efficiency of the wind wheel.

[0005] 2. Blade materials and manufacturing process: The blades are made of one or more high-performance fiber materials such as Kevlar fiber, aramid fiber, ultra-high molecular weight polyethylene fiber, graphene fiber, ceramic fiber and alumina fiber for blending and weaving. These high-performance fiber materials have the advantages of high strength and good toughness. The blending and weaving process can give full play to the advantages of each fiber material, so that the blades have excellent comprehensive performance. Subsequently, the blended and woven materials are composited with high-performance elastic materials. Through a special composite process, the high-performance elastic material is evenly distributed between the fiber materials, further enhancing the toughness and impact resistance of the blades. When impacted by external forces, the elastic material can effectively buffer the energy, prevent the blades from breaking or being damaged, and ensure the normal operation of the wind wheel.

[0006] 3. Blade edge sharp teeth design: High-strength and high-hardness sharp teeth are compounded on the positive blade edge of the blade. These sharp teeth are tightly combined with the blade body using a special manufacturing process, and their material hardness and strength have been carefully designed and computer simulation tested. When the wind wheel rotates at high speed, the sharp teeth on the blade edge can throw away incoming low-altitude weapons and cut and destroy them, greatly improving the interception efficiency of the wind wheel. Computer simulation results show that in the simulated low-altitude weapon attack scenario, the interception success rate of the wind wheel equipped with sharp teeth is 30%-40% higher than that of the wind wheel without sharp teeth.

[0007] 4. Stealth and compact design: In order to reduce the probability of the wind wheel being detected during operation, the present invention adopts a stealth and compact design. On the one hand, absorbing materials are selected to make some structural components of the wind wheel. These absorbing materials can absorb radar waves and reduce the radar reflection area. On the other hand, by optimizing the overall structural shape of the wind wheel to make its surface smoother and smoother, avoiding the appearance of right angles, edges and corners that are prone to strong reflections, the radar reflection signal is further reduced. At the same time, heat dissipation and heat insulation measures are taken on the power system and other heat-generating components of the wind wheel to reduce infrared radiation when the wind wheel is running, thereby achieving an all-round stealth effect.

[0008] 5. Power system: The power system of the wind wheel includes a drive motor, which is connected to the wind wheel through a speed changer. The drive motor has a variety of speed adjustment modes and can be flexibly adjusted according to different working environments and mission requirements. When facing incoming low-altitude weapons of different speeds and types, the control system can control the speed of the drive motor in real time according to the information obtained by the sensor, and accurately transmit power through the speed changer to keep the wind wheel in the best interception state. When the incoming target is detected to be at a faster speed, the drive motor can quickly increase the speed to enhance the interception capability of the wind wheel; when the target speed is slower, the speed is reduced to save energy and maintain a stable operating state. In addition, for the wind wheel used for large equipment, under normal conditions, the wind wheel can use natural wind power to drive to generate electricity and store electrical energy; when a low-altitude weapon is detected, the motor can immediately accelerate to provide additional power for the high-speed rotation of the wind wheel.

[0009] 6. Control system: The control system is one of the core parts of the present invention, including a sensor group, a central processing unit and an actuator. The sensor group is distributed in various key parts of the wind wheel and the surrounding environment, and can monitor the operating status of the wind wheel in real time, such as speed, blade stress, temperature and other parameters, wind speed, wind direction, air pressure, etc., as well as relevant information of incoming low-altitude weapons, such as speed, trajectory, model, etc. The central processing unit adopts a high-performance computing chip, which can quickly analyze and process the data fed back by the sensor group, judge the threat level of the incoming target through the preset algorithm and the computer simulation optimization model, and formulate corresponding interception strategies. Then, the central processing unit sends a control instruction to the actuator, and the actuator accurately adjusts the speed, angle and other parameters of the wind wheel according to the instruction to achieve effective interception of incoming low-altitude weapons. In addition, the wind wheel protection device control and detection system is connected to the entire protection system, and can obtain accurate information in the entire protection system in real time, including the operating status of other protection equipment, detailed data of incoming threats, etc., to achieve information sharing and collaborative protection. In a protection area containing multiple wind rotors and other protective equipment, each device can communicate and coordinate in real time through a networked control system to form an organic whole, greatly improving the protection efficiency and effectiveness.

[0010] 7. Energy supplement: The surface of the wind rotor blades is coated with photoelectric conversion coating, which can convert light energy into electrical energy. In an environment with light, whether it is natural light or artificial light, the photoelectric conversion coating can continue to work and provide energy supplement for the entire system, especially the individual protection system. By evenly coating the photoelectric conversion coating on the surface of the blades and combining it with an efficient energy storage and management system, the converted electrical energy can be effectively stored and used to drive some auxiliary equipment of the wind rotor, charge electronic equipment in the individual protection system, etc., thereby improving the energy utilization efficiency and independence of the entire protection system.

[0011] 8. Application scenario adaptation and retractable design: According to the size, orientation and protection requirements of application equipment and facilities such as individual combat helmets, tanks, warship islands, airport hangars, command posts, ammunition depots, oil depots, and nuclear power plants, wind wheels and wind wheel group devices of different sizes and performance parameters are customized and installed, and the protective device can be retracted and released freely. For individual combat helmets, a wind wheel device that can cover the entire helmet is designed, and the blade size is appropriately enlarged. The material focuses more on lightweight and flexibility to meet the flexible action needs of individual soldiers. Through clever buckle or folding structure design, it can be quickly retracted. For tanks, the wind wheel device needs to have higher strength and protection capabilities, and can operate stably in complex battlefield environments. It adopts a hydraulic or electric-driven retractable mechanism, which can be quickly retracted when it is necessary to hide in the jungle, and can be quickly opened for protection when encountering threats. For large facilities such as airport hangars, nuclear power plants, etc., wind wheel group devices are used. Through reasonable layout and coordinated control, all-round protection of large areas is achieved. The retraction and release of the wind wheel group is uniformly coordinated and controlled by the central control system. Through the reasonable layout and coordinated control of wind rotors and wind rotor groups, all-round and precise protection of various targets can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0021] 1. Manufacturing process of the wind wheel 1: When manufacturing the wind wheel 1, first select the appropriate high-performance fiber material according to the design requirements, and blend and weave it in a certain proportion. Put the blended fiber material into a special mold, and composite it with high-performance elastic materials through processes such as hot pressing to form the basic shape of the blade 11. Then, laser welding or special bonding technology is used to composite high-strength, high-hardness and sharp teeth on the positive cutting edge of the blade 11. After the blade 11 is manufactured, the multi-layer blades 11 are assembled through the central axis and connectors according to the lotus-shaped umbrella structure design. A predetermined distance is maintained between each layer of blades 11 to ensure the overall structural stability of the wind wheel 1, and at the same time, the retractable mechanism components are installed.

[0022] 2. Installation and debugging of the power system: Connect and debug the drive motor and the speed change device to ensure smooth and accurate power transmission between the two. Then, install the assembled power system on the base of the wind wheel 1 and connect it to the wind wheel 1 through the transmission shaft. During the installation process, strictly control the installation accuracy of each component to ensure that the drive motor can accurately control the speed and direction of the wind wheel 1. After the installation is completed, carry out comprehensive debugging work to test the operating status of the drive motor at different speeds and the response performance of the wind wheel 1 under different load conditions, and make necessary adjustments and optimizations based on the test results.

[0023] 3. Control system integration and testing: Install the sensor group in the key parts and surrounding environment of the wind wheel 1 to ensure that the sensor can accurately obtain various parameter information. Install the central processing unit and actuator in the control box and electrically connect them to the sensor group and the power system. Write and debug the software program of the control system, and test and optimize the control system by simulating various actual working conditions. During the test process, continuously adjust the algorithm and parameter settings so that the control system can respond quickly and accurately to various situations and achieve precise control of the wind wheel 1. At the same time, test the accuracy and timeliness of the retraction and extension control instructions.

[0024] 4. Installation and deployment of application scenarios: For individual combat helmets 5, the miniaturized wind wheel 1 device that is enlarged in size and can cover the entire helmet 5 is installed on the top or side of the helmet 5 through a special fixing bracket to ensure that the installation is firm and does not affect the line of sight and movement of the individual soldier, while ensuring that the retractable structure is easy to operate. For the chariot 3, according to the structural characteristics of the chariot 3, the wind wheel 1 device is installed at a suitable position on the roof or the side of the vehicle body, and the electrical system of the chariot 3 is appropriately modified to make it compatible with the power system and control system of the wind wheel 1, and the hydraulic or electric drive system of the retractable mechanism is adapted, installed and debugged. For large facilities such as airport hangars, nuclear power plants, etc., according to the layout and protection requirements of the facilities, the installation plan of the wind wheel 1 group is designed, and by establishing a unified control center, the centralized control and collaborative work of the wind wheel 1 group is realized, and the central system integration and debugging of the retractable control of the wind wheel 1 group is completed. After the installation and deployment are completed, the protection effect of wind wheel 1 and wind wheel 1 group devices in the actual application scenario is tested through computer simulation, and further optimization and improvement are carried out according to the simulation results, with a focus on optimizing the stability and reliability of the retraction and extension process.

[0025] 5. Hovering installation method: The lotus-shaped wind wheel 1 structure can also be installed in a hovering manner similar to a kite, using its lift to rotate in the air. This installation method has unique advantages, such as rapid deployment and flexible adjustment of position and height to adapt to different battlefield environments and protection needs. In the hovering installation, a high-strength cable is used to pull the wind wheel 1 to ensure its stability and controllability in the air. One end of the cable is connected to the wind wheel 1 device, and the other end is fixed to the ground or a mobile vehicle. By adjusting the length and tension of the cable, the position and height of the wind wheel 1 in the air can be accurately controlled. At the same time, in order to adapt to different wind directions and wind conditions, the angle and posture of the wind wheel 1 can also be adjusted to ensure that it is always in the best interception position. This installation method is particularly suitable for scenarios that require rapid deployment and flexible adjustment of the protection range, such as temporary protection of field troops, rapid deployment of important areas, etc. In the hovering state, the wind wheel 1 device can make full use of aerodynamic performance to achieve efficient wind energy conversion and interception efficiency. At the same time, through the traction and control system of the cable, it ensures that it operates stably in the air and responds to various low-altitude weapon threats at any time.

[0026] Example

[0027] 1. Single-soldier helmet 5 wind wheel 1 device

[0028] ·Structural design: Based on the portability and protection requirements of the single-soldier helmet 5, a wind wheel 1 that can completely cover the helmet 5 is designed by using computer simulation combined with ergonomic analysis. The diameter of the wind wheel 1 is set to 20-25 cm, the overall height is controlled to 10-15 cm, and the weight does not exceed 500 grams. The wind wheel 1 is composed of four layers of umbrella-shaped blades 11, the height of the central layer blades 11 is 4 cm, the height of the outer layer blades 11 increases by 1-2 cm in sequence, and the interval between each layer of blades 11 is 1.5-2 cm. The blades 11 are made of ultra-high molecular weight polyethylene fibers and aramid fibers in a 7:3 blended weaving ratio, and then composited with a lightweight high-performance elastic material with a density of 0.8-1.0g / cm3. Sharp serrations are set on the positive edge of the blade 11, the serration height is 0.5-1 cm, and the interval is 1-1.5 cm. According to computer simulation, this serration design can effectively cut and crush incoming suicide drones. A simple snap-on retractable structure is adopted to facilitate single-soldier operation.

[0029] · Protection effect: Through computer simulation of actual combat scenarios, when a small drone attacks at a speed of 40-60 km / h, the wind wheel 1 starts quickly. The simulation results show that the airflow generated by the high-speed rotation of the wind wheel 1 can cause the drone to deviate from its track, and the probability of the sharp teeth on the blade 11 cutting and damaging the drone is more than 80%. At the same time, some broken parts can be thrown away, effectively reducing the threat of drones to individual soldiers. When the light intensity of the wind wheel 1 blade 11 is 1000-1500 lux, the photoelectric conversion coating on the surface of the wind wheel 1 blade 11 can provide 80-120 mAh of power replenishment for the electronic equipment of a single soldier per hour.

[0030] 2. Wind wheel 1 device on the top (four sides) of the chariot 3

[0031] ·Structural design: In view of the complex combat environment and high protection requirements of the tank 3, the computer simulated the influence of wind wheels 1 of different sizes on the airflow field around the tank 3, and determined that the diameter of the top wind wheel 1 is 1.5-2 meters, and it is composed of five layers of umbrella-shaped blades 11. The height of the central layer blade 11 is 15-20 cm, and the diameter of each layer of blades 11 increases by 15-20 cm layer by layer, and the interval between blades 11 is 3-5 cm; the diameter of the four side wind wheels 1 is 1-1.5 meters, and the angle of the blade 11 is optimized to be 45-60 degrees with the side of the vehicle body according to the direction of the side attack. The blade 11 is made of Kevlar fiber, ceramic fiber and graphene fiber blended and woven in a ratio of 5:3:2, and then composited with a high-performance elastic material with a tensile strength of 50-60MPa. The blade 11 is provided with sharp serrations on the positive edge of the blade 11, with a height of 1-1.5 cm and an interval of 1.5-2 cm, so as to enhance the cutting and crushing ability of suicide drones, cruise missiles, etc. The hydraulically driven retractable mechanism can achieve rapid folding and opening.

[0032] · Protection effect: Through computer simulation of multi-target attack scenarios, when encountering enemy low-altitude missiles and drone groups, the wind wheel 1 group quickly starts. The simulation results show that the protection barrier formed by the high-speed rotation of the wind wheel 1 can achieve a comprehensive interception success rate of more than 85% for incoming weapons. The sharp serrations on the blade 11 can effectively cut and crush the incoming target, throwing its parts away. At the same time, the wind force generated by the wind wheel 1 can change the direction of the incoming target to a certain extent, effectively protecting the safety of the tank 3 and the personnel inside the vehicle. Under normal conditions, the wind wheel 1 can use wind power to generate electricity and store electricity in preparation for emergency situations.

[0033] 3. Wind wheel 1 device on the top (four sides) of command post 4

[0034] ·Structural design: Considering the importance of the command post 4 and the all-round protection requirements, computational fluid dynamics software is used to simulate the protection effect under different wind wheel 1 structural parameters, and the top wind wheel 1 is determined to have a diameter of 3-4 meters, consisting of seven layers of umbrella-shaped blades 11. The height of the central layer blade 11 is 25-30 cm, and the diameter of each layer of blades 11 increases by 20-25 cm layer by layer, and the interval between blades 11 is 4-6 cm; the diameter of the four side wind wheels 1 is 2-3 meters, and the seven-layer blade 11 structure is also adopted. The blade 11 is made of aramid fiber, alumina fiber and ultra-high molecular weight polyethylene fiber blended and woven in a ratio of 4:3:3, and is composited with high-performance elastic materials with a compression strength of 80-100MPa. The sharp serrations on the positive edge of the blade 11 are 1.5-2 cm high and 2-2.5 cm apart, which can effectively deal with suicide drones, cruise missiles, etc. It is uniformly operated by the central control system through an electrically controlled retractable mechanism.

[0035] · Protection effect: By simulating enemy air raid scenarios on computers, when there are low-altitude penetrating cruise missiles and drones, the wind wheel 1 group adjusts in real time according to the best strategy calculated by simulation. The simulation results show that the wind wheel 1 device can intercept cruise missiles with a success rate of more than 90%, and intercept drones with a success rate of more than 95%. The sharp serrations on the blade 11 can cut and smash incoming targets and throw them away. The wind force generated by the wind wheel 1 helps to interfere with the flight trajectory of incoming targets, providing reliable protection for the command post 4. In normal times, the wind wheel 1 can generate and store electricity to provide additional energy for the command post 4.

[0036] 4. Wind wheel 1 device on the outer side of ship 2 (anti-suicide unmanned boat)

[0037] ·Structural design: In combination with the characteristics of the marine navigation environment of the ship 2, the performance of the wind wheel 1 with different structural parameters under complex sea conditions is simulated by computer, and it is determined that a wind wheel 1 with a diameter of 2.5-3.5 meters is installed on the outside of the ship 2, which is composed of six layers of umbrella-shaped blades 11. The height of the central layer blade 11 is 20-25 cm, and the diameter of each layer of blades 11 increases by 20-25 cm layer by layer, and the interval between the blades 11 is 3-5 cm. The blades 11 are made of waterproof Kevlar fiber, ceramic fiber and graphene fiber blended and woven in a ratio of 6:2:2, and composited with high-performance elastic materials with good seawater corrosion resistance and fatigue resistance. Sharp serrations are set on the positive edge of the blade 11, with a serration height of 1-1.5 cm and an interval of 1.5-2 cm to meet the cutting and crushing requirements of suicide unmanned boats, etc. The retracting and releasing mechanism is made of corrosion-resistant materials, and the retracting and releasing is achieved through hydraulic and mechanical linkage.

[0038] · Protection effect: Through computer simulation of maritime attack scenarios, when encountering suicide unmanned boats and torpedo attacks, the wind wheel 1 starts up quickly. The simulation results show that the water flow and impact force generated by the high-speed rotation of the wind wheel 1 can cause the incoming unmanned boats and torpedoes to deviate from their tracks, and the sharp teeth on the blades 11 have a probability of cutting and damaging them of more than 85%, which can cut and break part of the structure of the unmanned boat and throw it away, effectively improving the maritime defense capability of the ship 2. At the same time, the wind wheel 1 can use the flow of seawater to generate electricity and store electricity in normal times, providing power for defense at critical moments.

[0039] 5. Temporary protection wind wheel 1 device for field troops

[0040] ·Structural design: Aiming at the temporary protection needs of field troops, a quickly deployable hovering wind wheel 1 device is designed. The wind wheel 1 has a diameter of 1-1.5 meters and consists of four layers of umbrella-shaped blades 11. The height of the central layer blades 11 is 10-15 cm. The diameter of each layer of blades 11 increases by 10-15 cm layer by layer, and the blades 11 are spaced 2-3 cm apart. The blades 11 are made of high-strength, lightweight Kevlar fiber and ultra-high molecular weight polyethylene fiber blended and woven, and then composited with high-performance elastic materials to ensure that the blades 11 are easy to carry and quickly deployed while ensuring strength. Sharp serrations are set on the positive edge of the blade 11, with a serration height of 0.8-1 cm and an interval of 1-1.2 cm to effectively intercept incoming low-altitude weapons. High-strength, wear-resistant and corrosion-resistant cables are used for traction. The length of the cables can be adjusted according to actual protection needs and terrain conditions. The general length range is 5-10 meters. The retraction and release of the cables are controlled by an electric winch to achieve rapid deployment and recovery of the wind wheel 1 in the air.

[0041] · Protection effect: By simulating the low-altitude weapon attack scene in the field environment with a computer, when enemy drones, rockets, etc. attack at different speeds and angles, the hovering wind wheel 1 device can quickly start and adjust its position. The simulation results show that under wind conditions of 5-10, the wind wheel 1 device can still hover stably and effectively intercept the incoming target, and the interception success rate of low-altitude weapons is more than 75%. Its interception efficiency is mainly due to the strong airflow generated by the high-speed rotation of the wind wheel 1, which can make the incoming target deviate from the original trajectory. At the same time, the sharp teeth of the blade 11 can cut and destroy the target, reducing its threat level. In addition, this hovering wind wheel 1 device can be deployed or recovered within a few minutes, which greatly improves the protection flexibility and adaptability of the field troops and provides a reliable low-altitude protection method for the troops in a complex and changeable battlefield environment.
