Description

Technical Field

[0001] This utility model belongs to the field of low-altitude defense technology, and specifically relates to a high-speed rotating wheel with brush bristles. Background Technology

[0002] With the rapid development of low-altitude aircraft technology, the frequent activities of various low-altitude intrusion targets (such as drones and small aircraft) in specific airspace areas pose significant challenges to the operational safety and regional security of critical civil and national security infrastructure (such as airports, energy storage and transportation facilities (oil depots, LNG receiving terminals), large transportation hubs (bridges), water conservancy facilities (dams), power hubs (substations), nuclear facilities, and related operational and transportation units). Existing defense systems suffer from high costs, insufficient detection capabilities in complex environments, and difficulties in multi-platform coordination, necessitating an efficient, economical, and adaptable solution. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed rotating wheel with brush bristles that can effectively defend against low-altitude intrusion targets, and is versatile and low in cost.

[0004] To achieve the above objectives, the solution of this utility model is as follows: a high-speed rotating wheel with brush bristles is provided, comprising a rotating wheel body and brush bristles. The brush bristles are fixed on the top surface of the rotating wheel body. The brush bristles are elastic and are arranged discretely from the center of the rotating wheel body to the outer periphery. The rotating wheel body is rotatably installed on equipment requiring low-altitude defense. The rotating wheel body drives the brush bristles to rotate at high speed to shear, intercept, and centrifugally throw away low-altitude intrusion targets.

[0005] Furthermore, the bristles are arranged in a cluster-like distribution, with multiple clusters of bristles arranged discretely from the center of the rotating wheel body outwards. The discrete arrangement includes radially linear distribution, spiral radial distribution, and grid distribution. The bristles are either straight or have their tops curved into hook shapes.

[0006] Furthermore, the top of the rotating wheel body is provided with a fixing hole or a strip groove, and the bottom of the brush bristles is directly pressed, welded or glued in the fixing hole and the strip groove, or multiple clusters of brush bristles are arranged and fixed on a strip base to form a brush strip, and the brush strip is fixed in the strip groove.

[0007] Furthermore, several strips are evenly distributed around the outer periphery of the rotating wheel body, and one end of each strip is fixed to the outer periphery edge of the rotating wheel body.

[0008] Furthermore, the strip is composite with a plurality of barbed sharp teeth, the strip is made of spring steel or polymer material, and the barbed sharp teeth are made of spring steel, alloy steel, boron nitride or silicon carbide.

[0009] Furthermore, the main body of the rotating wheel is hemispherical.

[0010] Furthermore, the rotating wheel body is disc-shaped and is used to install on equipment requiring low-altitude defense. A rotating device and a lifting device are provided between the disc-shaped rotating wheel body and the equipment requiring low-altitude defense. The top of the lifting device is connected to the center of the bottom surface of the rotating wheel body, and the bottom of the lifting device is connected to the rotating device. The rotating device is a motor, and the bottom of the motor is installed on the equipment requiring low-altitude defense through a connector.

[0011] Furthermore, the motor is a brushless high-speed motor with a speed of 3000~12000 revolutions per minute.

[0012] Furthermore, the material of the rotating wheel body is a polymer material, a micro-foamed material, or spring steel. The polymer material includes CFRP, ABS, PS, or PU, and the micro-foamed material is PEEK.

[0013] Furthermore, the brush bristles are made of steel wire, nylon wire, polyester wire, or composite fiber.

[0014] After adopting the above solution, the beneficial effects of this utility model are as follows: 1. This utility model uses a high-speed rotating wheel for low-altitude defense. The wheel body is equipped with brush filaments, which are arranged discretely from the center of the wheel body to the outer periphery. The wheel body drives the brush filaments to rotate at high speed to form a rotating cutting barrier. Combined with centrifugal force, it intercepts low-altitude intrusion targets. Compared with traditional air defense weapons (such as lasers and nets), it has the characteristics of low cost, simple structure, and no ammunition consumption, and is suitable for individual soldier and various equipment protection scenarios.

[0015] 2. The elastic properties of the bristles allow them to absorb some kinetic energy through deformation upon contact with low-altitude intruding targets (avoiding breakage), and then utilize the centrifugal force of high-speed rotation to convert the remaining kinetic energy into a lateral throwing force (achieving "using minimal force to achieve maximum effect"), thus cutting and brushing away the low-altitude intruding targets. Simultaneously, the elastic restoring force increases the contact time between the bristles and the target, improving cutting efficiency (such as continuous shearing of drone propellers). Compared to rigid interception structures (such as metal mesh), this reduces the impact load on the rotor body and motor, extending the equipment's lifespan. Attached Figure Description

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-14As shown, this application provides a high-speed rotating wheel with brush bristles, including a rotating wheel body 1 and brush bristles 3. The rotating wheel body 1 can be in the shape of a disc, a hemisphere, or other arcs. Brush bristles 3 are fixed on the top surface of the rotating wheel body 1. The brush bristles 3 are elastic steel wire, nylon wire, polyester wire, or composite fiber, etc. The brush bristles 3 are arranged discretely from the center of the rotating wheel body 1 to the outer periphery. The rotating wheel body 1 is rotatably mounted on equipment requiring low-altitude defense. The rotation of the rotating wheel body 1 is specifically driven by a rotating device, that is, a rotating device is installed at the bottom of the rotating wheel body 1. The rotating device can be a motor or other device capable of driving the rotating wheel body 1 to rotate. In this utility model, the rotating device is a motor. The motor can drive the rotating wheel body 1 and the brush filaments 3 on it to rotate at high speed. The motor is a brushless high-speed motor with a speed of 3000~12000 revolutions per minute. The brush filaments 3 form a rotating cutting barrier in this high-speed rotating state, which can cut, intercept and centrifugate low-altitude intrusion targets, thereby achieving effective handling of low-altitude threats. Moreover, the structure of the rotating wheel and the brush filaments 3 is simple, the cost is low, and the economic benefits are good.

[0020] Specifically, the brush bristles 3 are arranged in clusters, with each cluster consisting of multiple elastic steel wires, nylon filaments, or polyester filaments forming a unit. These clusters of bristles 3 are dispersed from the center of the rotating wheel body 1 towards its outer periphery, ensuring that the barrier formed by the high-speed rotation of the bristles 3 covers the top surface of the rotating wheel body 1 and guarantees a defensive effect. The bristles 3 can be straight or have a hooked shape at the top; a hooked shape at the top is preferred to enhance the destructive and cutting effect on low-altitude intruding targets.

[0021] Preferably, the brush bristles can be made of high-temperature alloy-reinforced steel wire, ceramic fiber-reinforced composite fiber, or carbon-ceramic composite fiber. The high-temperature alloy can be a nickel-based high-temperature alloy or a cobalt-based alloy, with a melting point above 1200℃, which can maintain good oxidation resistance and structural stability at high temperatures. Ceramic fiber-reinforced composite fibers and carbon-ceramic composite fibers not only have excellent crack toughness, capable of withstanding the instantaneous stress under explosive impact, but can also withstand temperatures up to 2000℃, allowing them to withstand the instantaneous high-temperature impact of a bomb explosion. The material will not melt, decompose, or collapse structurally in a short time, thus improving its service life.

[0022] The following explanation uses the formulas for the cutting force of the brush bristles and the centrifugal force of the rotating wheel to further illustrate this point: The formula for the cutting force of the bristles is:

[0023] In the formula, The minimum cutting force required for a single cluster of bristles; denoted by ρ, where ρ is the mass of the low-altitude intrusion target; v is the relative velocity of the low-altitude intrusion; and L is the effective cutting length of the bristles, which is generally less than the actual length of the bristles.

[0024] As shown by the formula above, to ensure the cutting force of the bristles is sufficient to effectively cut low-altitude intrusion targets, the effective cutting length of the bristles must be controlled. Under the same conditions of thickness, material, and bending coefficient, the shorter the bristles, the greater the cutting force. However, the bristles cannot be too short, otherwise the cutting range will be too small. In addition, for the bristles to effectively cut low-altitude intrusion targets, they also need a certain strength. To ensure a certain strength, the thickness of the bristles and the material of the steel wire need to be adjusted.

[0025] The formula for the centrifugal force of a spinning wheel is:

[0026] In the formula, The centrifugal force exerted by the rotating wheel on the debris, which is debris fragments that cut through low-altitude intrusion targets; For the mass of the wreckage; R is the angular velocity of the wheel; R is the radius of the wheel; G is the weight of the debris.

[0027] As shown by the above formula, the debris can be flung away by controlling the centrifugal force to be greater than the weight of the debris. Therefore, it is necessary to control the appropriate radius and rotation speed of the rotating wheel. It should be noted that the centrifugal force for flung away the debris includes not only the centrifugal force of the rotating wheel but also the centrifugal force of the brush bristles. However, the weight of the brush bristles is extremely small and will not be calculated here. Moreover, adding the centrifugal force of the brush bristles will only increase the centrifugal force, making it more effective at flung away the debris.

[0028] The following specific examples further illustrate this point: In Example 1, as Figure 1-4 The rotating wheel body 1 is hemispherical, and a keyway 11 is provided at the center of the bottom surface of the rotating wheel body 1. The keyway 11 is connected and fixed to the output shaft 21 of the motor. A flat key or spline connection can be used.

[0029] The material of the spinning wheel body 1 can be a polymer material or a micro-foamed material. The polymer material can be CFRP (carbon fiber reinforced composite), ABS (acrylonitrile-butadiene-styrene copolymer), PS (polystyrene) or PU (polyurethane). The micro-foamed material can be PEEK (ultra-light polyether ether ketone). CFRP and PEEK are preferred. CFRP has low density and high strength, which can control the weight of the spinning wheel body to 80-100g while ensuring impact resistance. PEEK has a foaming rate of 40%-50%, low density, and combines cushioning (reducing vibration transmission during rotation) and lightweight.

[0030] Furthermore, in this embodiment, the multiple clusters of brush bristles 3 are radially distributed in a straight line on the top surface of the rotating wheel body 1, as shown in the figure. Figure 1As shown, the multiple clusters of brush bristles 3 are evenly arranged along the six radii of the rotating wheel body 1. This arrangement is simple and easy to process. Of course, it is not limited to the arrangement along the six radii; it can also be one or more radii.

[0031] When installing the bristles 3, fixing holes 12 can be made on the top surface of the rotating wheel body 1 along the distribution position of the bristles 3. The bottom of each cluster of bristles 3 can be directly pressed, welded or glued into the fixing hole 12 to realize the installation of the bristles 3.

[0032] In Example 2, as Figure 5 The difference between this embodiment and embodiment one is that when the multi-cluster brush filaments 3 of this embodiment are distributed in a grid pattern on the top surface of the rotating wheel body 1, they can be densely distributed to cover most of the surface of the rotating wheel body 1, or they can be sparsely distributed, which can be set as needed.

[0033] In Example 3, as Figure 6-10 As shown, the difference between this embodiment and Embodiment 1 is that the multiple clusters of brush bristles 3 in this embodiment are distributed in a spiral radial pattern, that is, they are distributed in a spiral pattern extending outward from the center point of the rotating wheel body 1 to form several centrally symmetrical spiral lines, for example... Figure 6 The six spirals shown have good fluid control capabilities, can accurately guide the centrifugal flow field, enhance impact resistance and directional cutting ability, and provide good protective coverage, thus enhancing the defense effect.

[0034] In this embodiment, the brush bristles 3 can be installed by opening a fixing hole 12 on the top surface of the rotating wheel body 1, just as in Embodiment 1. In this embodiment, as shown... Figure 7-9 As shown, a spiral groove 13 can also be formed on the top surface of the rotating wheel body 1. The bottom of the brush bristles 3 can be directly pressed, welded, or glued into the spiral groove 13, or multiple clusters of brush bristles 3 can be arranged and fixed on a strip-shaped base belt 5 to form a brush strip. The structure of the brush strip is as follows: Figure 9 As shown, the brush strip is then fixed in the groove 13, which is a more convenient fixing method.

[0035] In Example 4, as Figure 10-14 As shown, the difference between this embodiment and embodiment one is that the rotating wheel body 1 in this embodiment is disc-shaped, and the distribution of the brush bristles 3 on the rotating wheel body 1 can be the same as in embodiments one to three, preferably adopting the spiral radial distribution of embodiment three.

[0036] This embodiment is preferably used for installation on large equipment requiring low-altitude defense, such as... Figure 13 The military combat vehicle 8 shown can have its rotating wheel body 1 mounted on its top, and it can also have the rotating wheel body 1 mounted on the sides of the vehicle for multi-directional protection, for example, in... Figure 13In this embodiment, three rotating wheel bodies 1 are installed on the side of the tank. The top and bottom surfaces of each rotating wheel body 1 are parallel to the side of the tank. Adjacent rotating wheel bodies 1 intersect along the length of the tank, while maintaining a certain horizontal distance along the width of the tank. This allows the three rotating wheel bodies 1 to cover most of the side of the tank, ensuring a defensive effect. This embodiment can also be installed on other military or civilian infrastructure equipment. Of course, these devices are not limited to disc-shaped rotating wheel bodies 1; the shape of the rotating wheel body 1 can be selected as needed.

[0037] The rotating wheel body 1 is made of corrosion-resistant spring steel plate or polyurethane plate, which has high strength and good high temperature resistance. The diameter of the brush bristles 3 can be larger than that of the brush bristles 3 of the hemispherical rotating wheel body 1 in the embodiment. Choosing thicker brush bristles 3 can enhance the interception effect.

[0038] In addition, in this embodiment, besides the rotating device for the motor installed between the rotating wheel body 1 and the equipment requiring low-altitude defense, a lifting device 6 is also provided. The top of the lifting device 6 is connected to the center of the bottom surface of the rotating wheel body 1, and the bottom of the lifting device 6 is connected to the motor. A connecting piece 7 is provided at the bottom of the motor and is installed on the equipment requiring low-altitude defense through the connecting piece 7. The motor can also be installed between the lifting device 6 and the rotating wheel body 1; this embodiment is not limited. The connecting piece 7 can be a flange or other structures, and can be adapted to different installed equipment. Specifically, for example... Figure 13 As shown, a housing 61 can be installed at the bottom of the lifting device 6, and a connector 7 can be installed at the bottom of the housing 61. The motor can be installed inside the housing 61.

[0039] Preferably, the lifting device 6 can be a vertically installed telescopic rod structure, which can be an electric telescopic rod or a hydraulic telescopic rod. The top of the telescopic rod can also be connected to the rotating wheel body 1 through the keyway 11. The extension and retraction of the telescopic rod can drive the rotating wheel body 1 to rise and fall. Especially for equipment installed on combat vehicles 8, which requires access from the top of the equipment, the lifting device 6 can drive the rotating wheel body 1 to rise to a sufficient height so that the combat personnel can first enter the space between the rotating wheel body 1 and the combat vehicle 8, and then enter the combat vehicle 8. Then, the lifting device 6 can drive the rotating wheel body 1 to fall. A small gap needs to be left between the rotating wheel body 1 and the equipment to ensure the defensive effect. Similarly, when the combat personnel want to leave the combat vehicle 8, the rotating wheel body 1 needs to be raised first.

[0040] In large equipment, the number of the rotating wheel body 1 is not limited to one; multiple rotating wheel bodies 1 can be arranged in an array for protection to ensure low-altitude defense effectiveness. For example, in large LNG carriers, such as... Figure 16As shown, there are multiple gas storage tanks 10 arranged in an array on an LNG carrier. A rotating wheel body 1 can be installed on each gas storage tank 10. The shape of the rotating wheel body 1 can be set according to the shape of the gas storage tank 10. For example, if the gas storage tank 10 is generally round, then a hemispherical rotating wheel body 1 is used.

[0041] In Example 5, as Figure 14-15 As shown, this embodiment is based on the above embodiment, and a strip 9 structure is added to the outer periphery of the rotating wheel body 1. The strip 9 is a whip-like strip structure. Several strips 9 are evenly distributed along the outer periphery of the rotating wheel body 1. One end of the strip 9 is fixed to the outer periphery edge of the rotating wheel body 1. When the rotating wheel body 1 rotates at high speed, the strip 9 will also rotate at high speed, which can also provide shear force and centrifugal force to increase the defense area of ​​the rotating wheel body 1.

[0042] Preferably, a counterweight 92 is installed at the other end of the cable 9. The counterweight 92 can be a gravity ball or a gravity block, preferably a gravity ball. While the rotating wheel body 1 is rotating at high speed, the gravity ball at the end of the cable 9 will drive the cable 9 to rotate at high speed. The gravity ball plays a balancing and stabilizing role.

[0043] Specifically, the material of the strip 9 is spring steel or polymer material, including ultra-high molecular weight polyethylene fiber and aramid, etc. The strip 9 can be formed by twisting ultra-high molecular weight polyethylene fiber and aramid in a 3:1 ratio.

[0044] Preferably, the bar 9 has a plurality of barbed teeth 91, which are made of spring steel, alloy steel, boron nitride or silicon carbide, to enhance the cutting force and strength of the bar 9 and improve the defensive effect.

[0045] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
