Description

Technical Field

[0001] This invention relates to the field of explosives equipment, and more specifically to the design of unmanned obstacle-clearing equipment that optimizes safety and efficiency. Background Technology

[0002] Obstacle clearing equipment is a specialized device designed to clear and destroy various obstacles. Its core function is to use its onboard explosive charge, powered by fuel or explosives, to carry out controlled blasting at the target obstacle, thereby creating a safe passage for personnel, equipment, or other vehicles. Obstacle clearing equipment has a wide range of applications. For example, in natural scientific exploration, it is used to clear large natural obstacles blocking routes; in mining, it is used to perform rock blasting operations; and in military applications, it is used to clear beach fortifications during amphibious operations, clearing key obstacles for amphibious forces to successfully land.

[0003] In existing technologies, taking obstacle-breaking operations in aquatic environments as an example, it is necessary to dispatch professional personnel to operate boats or dive to approach the obstacle and directly install the obstacle-breaking equipment on the target.

[0004] While this technical solution can clear obstacles, it suffers from the following drawbacks. Firstly, combat or engineering personnel must be extremely close to the target, placing them in a high-risk environment. Any miscalculation in the timing of the blast can easily lead to a safety accident. Secondly, whether operated directly by personnel or requiring precise remote control, the entire process necessitates allowing ample time for personnel to approach, evacuate, or maintain a safe distance. This results in a slow and time-consuming obstacle-clearing operation, failing to meet the demands for speed. Summary of the Invention

[0005] The purpose of this invention is to provide a connection device, obstacle-clearing device, and obstacle-clearing method suitable for unmanned obstacle-clearing equipment. A purely mechanical automatic padlock is employed to achieve automatic connection and clamping between the obstacle-clearing device and the obstacle. This solution achieves fully automated deployment, eliminating the need for personnel to approach or perform precise remote control, fundamentally eliminating safety risks during operation; the deployment process is rapid, completed only in the instant the unmanned vessel collides with the obstacle, improving the efficiency and speed of obstacle-clearing operations.

[0006] A connection device suitable for unmanned obstacle-breaking equipment includes a main frame for connecting a blasting section, characterized in that: it further includes a clamping device connected to the main frame, the clamping device including at least two clamping units, each clamping unit including a gripper and a hinged arm connected to the gripper and hinged to the main frame;

[0007] It also includes a collision device movably connected to the articulated arm, the collision device being configured to cause at least two of the grippers to move closer to each other when the collision device collides with an obstacle;

[0008] It also includes a locking device mounted on the main frame, the locking device being configured to lock the position of the gripper by fixing the collision device.

[0009] As a preferred embodiment of the present invention, the collision device includes a collision block for colliding with an obstacle, the collision block having a groove, and the hinged arm including a hinged end connected to the main frame and a sliding end connected to the groove.

[0010] As a preferred embodiment of the present invention, the collision device includes a slide bar connected to the collision block, and the slide bar has a locking groove for the locking device to be inserted to complete the locking action.

[0011] As a preferred embodiment of the present invention, the locking groove comprises at least two sets, namely an open groove and a closed groove. The open groove is configured such that when the locking device is inserted, the clamping device is in an open state, and the closed groove is configured such that when the locking device is inserted, the clamping device is in a closed state.

[0012] As a preferred embodiment of the present invention, the locking device includes a lock seat, a lock shaft slidably connected to the lock seat, an elastic member connected to the lock shaft, and an insertion head mounted on the lock shaft, wherein the elastic member is used to apply a spring force to the insertion head in the direction of the slide bar.

[0013] As a preferred embodiment of the present invention, the insertion head is a beveled insertion head, and the locking groove is a beveled groove that matches the beveled insertion head.

[0014] As a preferred embodiment of the present invention, the clamping device consists of two sets, namely a main clamp and an auxiliary clamp. The main clamp is connected to the collision device, and the auxiliary clamp is connected to the main clamp via a linkage rod.

[0015] As a preferred embodiment of the present invention, the gripper end is provided with a stabilizing block for increasing the contact area.

[0016] The obstacle-clearing device includes a blasting section and a connecting device suitable for unmanned obstacle-clearing equipment, wherein the blasting section is connected to the main frame.

[0017] The obstacle-clearing method of the obstacle-clearing device according to the claim 1 includes the following steps:

[0018] Connect the blasting section to the main frame, and adjust the clamping device to the open state;

[0019] The unmanned surface vessel, equipped with the explosive device, travels to the target location.

[0020] When the collision device collides with the obstacle, it causes the clamping device to automatically clamp and fix the obstacle.

[0021] The unmanned surface vessel was separated from the explosive section.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The clamping action is triggered by collision, eliminating the need for manual intervention and significantly improving operational safety; at the same time, the mechanical linkage ensures that the clamping and locking process is completed instantly, greatly improving obstacle-breaking efficiency.

[0024] 2. The cooperation between the slide and the sliding end accurately converts the linear motion of the collision block into the rotational motion of the articulated arm, thereby driving the gripper to close. The structure is simple and the action response is rapid and definite.

[0025] 3. The locking groove on the slider, in conjunction with the locking device, securely holds the clamping device in the closed position after a collision trigger, preventing accidental release and ensuring the reliability of the warhead deployment. The inclusion of open and closed slots allows operators to preset the device state according to mission requirements and automatically lock it upon triggering, enhancing the equipment's applicability and operational controllability.

[0026] 4. The elastic element provides continuous elastic force to the locking shaft, enabling it to automatically find and engage with the locking groove, ensuring the automatic completion of the locking action. The structure is simple and highly reliable.

[0027] 5. The inclined surface of the inclined block and the inclined groove can produce a self-locking effect, effectively resisting vibration and impact, preventing the locking shaft from coming out of the locking groove, and further improving the connection reliability after installation.

[0028] 6. Through the cooperation of the main clamp and the auxiliary clamp, multi-point gripping is achieved, enabling the device to more stably grasp obstacles that are large in size or irregular in shape.

[0029] 7. The auxiliary clamp does not require a separate collision device. Instead, it operates through a linkage rod, which not only saves manufacturing costs but also saves installation space, thus avoiding spatial interference with the explosive section.

[0030] 8. The stabilizing clamp increases friction and disperses pressure, ensuring the device remains firmly connected even under strong water flow impact, reducing the probability of accidental detachment. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings.

[0038] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0039] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this specification. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0040] The invention will be further described in detail below with reference to the accompanying drawings. A connection device suitable for unmanned obstacle-clearing equipment, such as... Figure 1 and Figure 3 As shown, its

[0041] It mainly includes a main frame 1, a clamping device 2, a collision device 3, and a locking device 4. The components achieve automatic clamping function through mechanical linkage.

[0042] The main frame 1, as the core load-bearing component, can be welded from high-strength steel. It has a frame structure with connection holes at the top for fixing the explosive part 9, and is connected to the clamping device 2 at the bottom through hinge points.

[0043] The clamping device 2 includes at least two clamping units, each clamping unit consisting of a gripper 21 and a hinged arm 22. The gripper 21 has an arc-shaped claw structure, and a stabilizing block 23 is provided at the end to increase the contact area. Figure 2 for Figure 1 A magnified view of the details at point A, such as Figure 2 As shown, one end of the hinged arm 22 is connected to the gripper 21, and the other end is hinged to the main frame 1 through the hinge end 221. The sliding end 222 is movably connected to the collision device 3.

[0044] The collision device 3 is one of the key technical features of this invention. Its core function is to convert the kinetic energy of the collision into a mechanical signal for clamping action. The collision device 3 mainly includes a collision block 31 and a slider 32.

[0045] The collision block 31 is located at the foremost end of the device and features a blunt-head design to disperse collision stress. For example, its material can be forged steel or aluminum alloy to balance strength and weight. The collision block 31 has a groove 34, which is a straight channel that forms a sliding fit with the sliding end 222 of the hinge arm 22.

[0046] When the collision block 31 of the unmanned surface vessel comes into contact with an obstacle while it is moving, the collision block 31 is impacted and moves backward in a straight line. It drives the sliding end 222 to move through the slide groove 34, thereby driving the articulated arm 22 to rotate around the articulated end 221 and realize the closing of the gripper 21.

[0047] The slide bar 32 is rigidly connected to the collision block 31 or integrally formed. The slide bar 32 is machined with a locking groove 33, which includes at least two sets of slots: open slot 331 and closed slot 332. The open slot 331 is used for the locking device 4 to be inserted when the clamping device 2 is open, and the closed slot 332 is used for locking the locking device 4 to be inserted after the clamp is closed.

[0048] The movement trajectory of the slider 32 is guided by the guide sleeve 35, ensuring the accuracy of linear motion. This design allows for seamless connection between the clamping and locking actions after a collision is triggered, with the entire process completed purely mechanically without electronic intervention. The purely mechanical structure of the collision device 3 avoids the risk of electronic component failure in explosive environments, resulting in a short response time and improved reliability. The cooperation between the slide groove 34 and the sliding end 222 precisely converts linear motion into rotational motion, ensuring a uniform distribution of clamping force, making it suitable for obstacles of various shapes.

[0049] like Figure 2 As shown, the locking device 4 is another key component, whose function is to automatically lock the position of the clamping device 2 after a collision is triggered, preventing accidental release. The locking device 4 includes a lock seat, a lock shaft 42, an elastic element 43, and an insertion head 41.

[0050] The lock seat is fixed to the main frame 1 and has an internal slide for the locking shaft 42 to slide. The locking shaft 42 is a cylindrical rod, which, for example, can be made of stainless steel for corrosion resistance. The insertion head 41 is mounted on the end of the locking shaft 42 and is designed as a wedge structure to match the wedge groove of the locking groove 33, using the wedge self-locking effect to enhance the locking force. The elastic element 43 can be a compression spring, sleeved on the locking shaft 42, to provide the insertion head 41 with a continuous elastic force toward the slide bar 32.

[0051] With the clamping device 2 open, the insertion head 41 is pushed into the slot 331 by the elastic element 43, stabilizing the device. When a collision occurs, i.e., the collision block 31 collides with an obstacle, such as a rail fort in the water, the slide bar 32 moves under the force of the collision and slides backward naturally. Due to the inclined surface of the insertion head 41 and the locking slot 33, the insertion head 41 slides smoothly out of the slot 331, while the closed slot 332 approaches the insertion head 41. The elastic element 43 automatically pushes the insertion head 41 into the closed slot 332, completing the locking. Figure 3 As shown, at this time, the two clamps 21 are in a closed and retracted state, holding the obstacle rail rock.

[0052] In some embodiments, the clamping device 2 can be configured with two systems: a main clamp 28 and an auxiliary clamp 29. The main clamp 28 is directly connected to the collision device 3, and the auxiliary clamp 29 is linked to the main clamp 28 via a connecting rod 5. The connecting rod 5 is a rigid connecting rod, and can be, for example, a hinged or ball joint connection to ensure synchronized movement. The surface of the stabilizing block 23 at the end of the gripper 21 can be provided with anti-slip texture, and can be, for example, covered with rubber or textured steel to increase friction.

[0053] The dual-grip design expands the gripping range, allowing the device to adapt to obstacles of different sizes. Linkage rod 5 simplifies the structure, avoids redundancy from multiple collision mechanisms, and reduces manufacturing costs.

[0054] like Figure 4 As shown, the obstacle breaching device is integrated with the explosive section 9 and the aforementioned connecting device. The explosive section 9 can be, for example, an explosive charge or a fuel container, fixed to the main frame 1 by bolts. The unmanned surface vessel (USV), serving as a transport platform, has a quick-release mechanism on its deck to facilitate the rapid installation and disassembly of the obstacle breaching device.

[0055] The steps for overcoming obstacles are as follows:

[0056] First, connect the blasting section 9 to the main frame 1, manually adjust the clamping device 2 to the open state, and ensure that the insertion head 41 of the locking device 4 is engaged in the slot 331.

[0057] Subsequently, the unmanned surface vessel, equipped with obstacle-clearing equipment, headed toward the target at a speed controlled between 5 and 10 knots to optimize collision accuracy.

[0058] Subsequently, a collision is triggered, which is also a key step of the present invention. After the collision block 31 comes into contact with the obstacle, it moves backward and drives the two grippers 21 to close through the cooperation of the slide groove 34 and the sliding end 222. At the same time, the slide bar 32 moves to align the closing groove 332 with the insertion head 41, and the locking device 4 automatically completes the locking.

[0059] Finally, the unmanned surface vessel (USV) separated from the obstacle-clearing equipment via a quick-release mechanism, and after withdrawing to a safe area, the explosive section 9 was remotely detonated.

[0060] The entire fully automated process eliminates human intervention, reducing deployment time to less than one minute and significantly improving efficiency. Mechanical triggering ensures safety in high-risk environments.
