Description

Technical Field

[0001] This invention relates to the field of unmanned equipment deployment technology, and in particular to a propulsion platform for attaching explosive spikes to loads. Background Technology

[0002] In modern urban warfare, counter-terrorism and stability maintenance, mountain search and rescue, and emergency response to natural disasters such as earthquakes, the rapid deployment of surveillance robots, eavesdropping robots, communication relay equipment, and directional destruction devices on the exterior facades of target areas has become a key means to improve situational awareness and mission response efficiency. However, because target areas are often located at high altitudes, in dangerous locations, or inaccessible to personnel, traditional manual deployment methods have significant limitations.

[0003] Currently, some technologies have attempted to use drones for remote equipment deployment or facade attachment, but they generally face the following technical bottlenecks: 1. Poor reliability of attachment mechanisms: Existing drone facade deployment technologies mostly use magnetic attraction, adhesive, or mechanical gripper methods. These methods have high requirements for surface material, flatness, and cleanliness, making them unsuitable for rough, damp, non-metallic, or high-hardness surfaces (such as rocks, concrete, and coated metals), resulting in a high failure rate and easy equipment detachment. 2. Lack of effective thrust cancellation mechanisms: Some technical solutions use catapult or propulsion methods to launch equipment towards the target surface, but because the release of forward kinetic energy at the moment of impact is not fully considered, the equipment is prone to rebound, displacement, or damage after impact, making stable fixation impossible, especially on hard surfaces.

[0004] Therefore, there is an urgent need for a comprehensive solution that can achieve remote, efficient, and stable deployment in complex environments to meet the pressing need for "efficient and reliable" facade control in modern battlefields and emergency scenarios. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems by providing a propulsion nail attachment load platform, thereby resolving the technical issues of poor reliability and easy detachment of equipment attachments in traditional attachment load platforms.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a propulsion platform for attaching explosive nails, comprising a propulsion unit, an explosive nail structure, and a load platform. The propulsion unit is used to propel the device to move in one direction. The explosive nail structure is installed at the front end of the propulsion unit in the forward direction. The explosive nail structure can pierce and fix to the outer surface of a vertical object. The explosive nail structure can act on the load platform in the opposite direction of the forward direction.

[0007] Furthermore, the propulsion unit includes a first housing, an igniter, and a propellant. The first housing has a placement cavity, and both the igniter and the propellant are installed in the placement cavity. The igniter can ignite the propellant. A plurality of nozzles are evenly distributed around the outer periphery of the first housing. One end of each nozzle is connected to the placement cavity, and the other end is positioned towards the rear end of the propulsion unit.

[0008] Furthermore, the nozzle is a Laval nozzle structure.

[0009] Furthermore, the igniter is ring-shaped, the propellant is cylindrical, one end of the propellant abuts against the igniter, and a plurality of propellants are evenly and alternately arranged in the placement cavity.

[0010] Furthermore, the detonating nail structure includes a long nail, a detonator, a spring, and a triggerable safety device. A mounting hole is coaxially provided in the middle of the first housing, and the mounting hole opens in the forward direction. The spring, detonator, and the rear of the long nail are slidably installed in the mounting hole from the inside to the outside. The rear end of the long nail is set as a firing pin, and the front end of the long nail extends out from the opening. A triggerable safety device is provided between the detonator and the firing pin. When the long nail compresses the spring to its limit position, the triggerable safety device is released, and the firing pin triggers the detonator to explode.

[0011] Furthermore, the triggerable safety includes a safety ball and a relief groove. The safety ball is located inside the mounting hole and offset from the central axis of the mounting hole. The safety ball is located between the detonator and the firing pin. The relief groove is located on the inner wall of the mounting hole and is located at the limit position of the spring compression.

[0012] Furthermore, a wedge-shaped placement groove is provided on the side of the detonator end, and the safety ball is located in the wedge-shaped placement groove.

[0013] Furthermore, the load platform includes a second housing, an external rotor motor, a sheave, a nylon rope, and a connecting flange. One end of the second housing is detachably docked with the rear end of the first housing, and the other end of the second housing is configured as a load surface. The central shaft of the external rotor motor is fixedly mounted on the second housing, the sheave is coaxially fixedly mounted on the external rotor motor, one end of the nylon rope is fixedly connected to the sheave, the nylon rope is wound around the sheave, and the other end of the nylon rope is connected to the connecting flange, which is fixedly connected to the rear end of the second housing.

[0014] Furthermore, a battery pack is provided on the load surface, which can supply power to the external rotor motor and the equipment on the load surface.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects:

[0016] 1. When this invention is used, the propulsion unit generates thrust to push the entire device at high speed toward the target facade. The explosive nail structure punctures and fixes itself to the surface of the vertical object at the moment of impact. At the same time, the reaction force stabilizes the load platform at the target position, solving the problem of high failure rate and easy detachment of traditional attachment methods on complex surfaces (such as rough, non-metallic, and high-hardness surfaces).

[0017] 2. This invention, through the design of the Laval nozzle structure, improves the expansion efficiency and thrust conversion rate of the propellant combustion gas, enabling the device to achieve higher propulsion speeds over short distances and enhancing the long-range and precise deployment capabilities. The combination of annular igniters and cylindrical propellant allows for multi-point synchronous ignition, ensuring uniform propellant combustion and stable thrust, thus preventing yaw or deployment failures caused by uneven ignition.

[0018] 3. This invention, through the coordinated arrangement of the spring, detonator, and triggerable safety mechanism in the explosive nail structure, achieves automatic safety release and detonation of the detonator upon impact, allowing the long nail to penetrate the target surface at high speed for rapid and reliable mechanical fixation, thus improving the deployment success rate and stability. The combination of the safety ball and the clearance groove ensures that the safety is only released when the spring is compressed to its limit, preventing accidental triggering or premature detonation and enhancing the system's safety and reliability. The wedge-shaped placement groove ensures that the safety ball is stably positioned between the detonator and the firing pin in the initial state, further enhancing the anti-interference capability and structural compactness of the safety mechanism.

[0019] 4. This invention achieves automatic deployment and retraction of the nylon rope through the arrangement of the outer rotor motor and rope pulley in the load platform, facilitating the rapid deployment and retrieval of the load platform and improving the system's mobility and reusability; the fixed connection between the connecting flange and the second housing ensures that the load platform remains stably connected after propulsion separation, preventing load detachment due to impact or vibration; the battery pack provides independent power to the outer rotor motor and load equipment, enhancing the system's autonomous operation capability and making it suitable for complex task environments without external power.

Detailed Implementation

[0025] The specific implementation of the invention will be further described below with reference to the accompanying drawings.

[0026] In the description of this invention, it should be understood that the terms "center", "length", "width", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] like Figure 1As shown, a propulsion platform for attaching explosive spikes includes a propulsion unit 1, an explosive spike structure 2, and a load platform 3. The propulsion unit 1 provides propulsion power, enabling the entire device to move at high speed along the target direction. The explosive spike structure 2 is located at the front end of the propulsion unit 1 and is used to puncture and fix the device upon impact with the target surface. The load platform 3 is located at the rear end of the propulsion unit 1 and is used to carry the mission equipment 4, achieving stable deployment or suspension after the explosive spike structure 2 is fixed. The front end of the propulsion unit 1 has a conical shape, and the outer periphery of the load platform 3 has several guide plates to facilitate stable flight of the device.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the propulsion unit 1 includes a first housing 11, an igniter 12, and a propellant 13. The first housing 11 has a placement cavity 111 to accommodate the igniter 12 and the propellant 13. The igniter 12 is annular, and the propellant 13 is cylindrical. One end of the propellant 13 abuts against the igniter 12. Multiple propellants 13 are evenly spaced within the placement cavity 111 to ensure uniform thrust distribution during ignition. Specifically, a plurality of nozzles 112 are evenly distributed around the outer periphery of the first housing 11. One end of each nozzle 112 communicates with the placement cavity 111, and the other end faces the rear end of the propulsion unit 1, used to eject combustion gases rearward, thereby generating forward thrust. In this embodiment, the nozzle 112 is preferably a Laval nozzle structure to improve gas expansion efficiency and thrust conversion rate.

[0031] like Figure 3 and Figure 4As shown, in this embodiment, the explosive nail structure 2 includes a long nail 21, a detonator 22, a spring 23, and a triggerable safety 24. A mounting hole 113 is coaxially arranged in the middle of the first housing 11, opening forward. A limit switch is provided at the opening of the mounting hole 113 to prevent the long nail 21 from detaching. The spring 23, detonator 22, and the rear of the long nail 21 are sequentially slidably mounted in the mounting hole 113 from the inside out. Specifically, the rear end of the long nail 21 is configured as a firing pin 211, with its front end extending from the opening of the mounting hole 113. A triggerable safety 24 is provided between the detonator 22 and the firing pin 211. When the long nail 21 compresses the spring 23 to its limit position, the triggerable safety 24 is released, the firing pin 211 triggers the detonator 22 to explode, causing the long nail 21 to be fired at high speed into the target surface, achieving mechanical fixation. The triggerable safety 24 includes a safety ball 241 and a clearance groove 242. The safety ball 241 is located within the mounting hole 113 and offset from the central axis. In its initial state, it is positioned between the detonator 22 and the firing pin 211, serving as a blocking element. A clearance groove 242 is located on the inner wall of the mounting hole 113, at the extreme position of the compressed spring 23. When the spring 23 is fully compressed, the safety ball 241 enters the clearance groove 242, releasing the safety mechanism. To further enhance the stability of the safety mechanism, a wedge-shaped placement groove 221 is provided on the side of the detonator 22's end. Part of the safety ball 241 is located within the wedge-shaped placement groove 221, ensuring stable limiting in the non-triggered state.

[0032] For example Figure 2 As shown, the load platform 3 includes a second housing 31, an external rotor motor 32, a pulley 33, a nylon rope 34, and a connecting flange 35. One end of the second housing 31 is detachably dockable to the rear end of the first housing 11, and the other end is set as a load surface 311 for mounting the task equipment 4. Specifically, the central shaft of the external rotor motor 32 is fixedly installed inside the second housing 31, and the pulley 33 is coaxially fixedly installed on the external rotor motor 32. One end of the nylon rope 34 is fixed to and wound around the pulley 33, and the other end is connected to the connecting flange 35. The connecting flange 35 is fixedly connected to the rear end of the second housing 31 to ensure that the load platform 3 remains stably connected after propulsion separation. A battery pack 36 is also provided on the load surface 311 to provide independent power to the external rotor motor 32 and the load equipment, improving the system's autonomous operation capability and making it suitable for complex task environments without external power.

[0033] In operation, the propulsion unit 1 ignites, and the propellant 13 burns to generate high-pressure gas, which is ejected rearward through the nozzle 112, propelling the entire device at high speed toward the target's outer facade. Upon impact, the tip of the spike 21 contacts the target surface and compresses the spring 23. When the spring 23 is compressed to its limit, the safety ball 241 enters the clearance groove 242, triggering the safety 24 to release the safety. The firing pin 211 then triggers the detonator 22 to explode, and the spike 21 is propelled at high speed into the target surface, achieving a secure fixation. Simultaneously, the propulsion unit 1 and the load platform 3 are connected via a connecting flange 35 and a nylon rope 34. Depending on mission requirements, the external rotor motor 32 can drive the pulley 33 to rotate, slowly lowering the load platform 3 and its equipment below the target surface to perform concealed deployment or suspended monitoring tasks. It should be noted that wireless control of the igniter 12, the rotation of the external rotor motor 32, and the wireless connection to the mission equipment 4 are already mature technologies. The specific control technologies of the igniter 12, the external rotor motor 32, and the mission equipment 4 will not be described in detail in this application.
