Description

Technical Field

[0001] This invention relates to the field of structural blast protection technology, specifically to a quick-release blast protection cover system and construction method for the sidewalls of large docks during wartime. Background Technology

[0002] Large dry docks, as core facilities for ship construction and maintenance, occupy a crucial position in national defense and maritime strategy. However, their enormous size and vital strategic function make them highly vulnerable to precision strikes by the enemy. In modern warfare, the close-range destructive power of 100kg-class aerial bombs is extremely strong, and traditional dry dock structures are ill-equipped to withstand such impacts, potentially leading to damage to the dock walls, facility paralysis, and consequently affecting the ship construction and maintenance capabilities.

[0003] Meanwhile, large coastal shipyards often bear the dual responsibilities of wartime emergency support and peacetime production operations. Using fixed protective structures would not only affect the normal entry and exit of ships and construction operations, but also potentially reduce protective effectiveness due to prolonged exposure. Therefore, how to achieve rapid protection and rapid conversion of shipyards during wartime without disrupting peacetime production has become a pressing problem to be solved.

[0004] Currently, existing solutions for dry dock protection have the following shortcomings:

[0005] (1) The protective structure is fixed, which affects the daily production operations of the dock;

[0006] (2) It has limited anti-blast capability and is difficult to withstand the close-range explosion of a 100kg-class aerial bomb;

[0007] (3) The installation and disassembly process is cumbersome and cannot be quickly deployed in wartime. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the main purpose of this invention is to provide a protective system and construction method for existing large coastal docks that can be quickly installed / disassembled, so as to meet the multiple anti-destruction requirements in wartime and ensure the survivability and continuous operation capability of the dock in complex battlefield environments.

[0009] The technical solution of the present invention is as follows:

[0010] This invention proposes a quick-release and detachable blast-resistant protective cover system for the sidewalls of large shipyards during wartime, comprising:

[0011] Multiple modular magnetic explosion-proof protective covers are stored at the bottom of the dock, with electromagnetic adsorption units on their edges.

[0012] An expandable load-bearing track system is installed on the side wall of the dock and extends along the longitudinal direction of the side wall. It is suitable for extending out and locking from the state of being stored in the first groove of the side wall of the dock in the event of a warning signal.

[0013] An automated operating device is configured to operate on the deployable load-bearing track system, and is suitable for picking up multiple protective cover plates from the bottom of the dock and transporting them to a designated height on the deployable load-bearing track system for continuous installation when a warning signal is issued, and for disassembling the installed protective cover plates and returning them to the bottom of the dock after the warning signal is lifted.

[0014] Furthermore, once multiple modular magnetic explosion-proof protective covers are installed in place, the electromagnetic adsorption unit is activated, causing adjacent covers to attract and connect with each other, forming the explosion-proof cover protection system for the dock sidewall.

[0015] Preferably, the deployable support rail system includes multiple deployable support rails, which are uniformly installed along a predetermined distance on the surface of the dock sidewall. Each deployable support rail includes:

[0016] Two vertical support rods are set parallel to the first groove on the outside of the dock side wall, serving as the travel track for the automated operation device;

[0017] Multiple horizontal support rods are horizontally connected between two vertical support rods at predetermined intervals, suitable for installing and fixing modular magnetic explosion-proof protective covers;

[0018] A hydraulic support mechanism is installed in the first groove on the side wall of the dock and connected to the vertical support rod. It is used to drive the vertical support rod and the horizontal bearing rod to move between being housed in the first groove and extending outward and locking to the side wall of the dock at a predetermined distance.

[0019] Preferably, the hydraulic support mechanism includes multiple pairs of hydraulic support pipes, which are evenly arranged in the first groove along the height direction of the vertical support rod. One end of each pair of hydraulic support pipes is connected to the side wall of the dock, and the other end is hinged to the vertical support rod. Each pair of hydraulic support pipes is adapted to extend under hydraulic pressure when a warning signal is received, pushing the vertical support rod to extend outward along a preset trajectory, and mechanically locking by a hydraulic lock after reaching the maximum stroke.

[0020] Preferably, each of the modular magnetic explosion-proof protective covers has at least one set of positioning components on its inner side, and the positioning components are adapted to be fitted and locked with the transverse support rod.

[0021] Preferably, each group of positioning components includes two spaced-apart convex positioning keys, and the space between the two convex positioning keys is adapted to the size of the transverse support rod.

[0022] Preferably, each of the vertical support rods is an H-beam, and the outer flange surface of the H-beam forms the travel track of the automated operation device; and / or, each of the transverse support rods is a square steel tube.

[0023] Preferably, the automated operation device includes:

[0024] A walking mechanism is adapted to be installed on the vertical support rod and is used to drive the automated operation device to slide on the walking track;

[0025] The robotic arm is a multi-segment robotic arm that can rotate and extend freely, with one end fixedly connected to the walking mechanism;

[0026] The end gripper is connected to the other end of the robotic arm and is used to grip and lock the modular magnetic explosion-proof protective cover.

[0027] Preferably, the walking mechanism includes:

[0028] The C-shaped traveling trolley is fastened to the vertical support rod;

[0029] Guide wheels are installed in pairs on the inside of the C-shaped traveling trolley and are in contact with the surface of the vertical support rod;

[0030] A drive assembly, mounted on the C-shaped traveling trolley, is used to drive the C-shaped traveling trolley to slide up and down along the vertical support rod.

[0031] Preferably, it also includes a central control system, which is communicatively connected to the deployable load-bearing track system, the automated operation device, and the electromagnetic adsorption unit, and

[0032] Suitable for performing the following operations upon receiving a warning signal:

[0033] Control the deployment and locking of the deployable load-bearing track system;

[0034] The automated operation device is controlled to perform the installation of the protective cover plate, and after the installation is completed, the electromagnetic adsorption unit is energized to form an explosion-proof cover plate protection system for the dock sidewall.

[0035] And upon receiving the warning cancellation signal, perform the following operations:

[0036] The system controls the electromagnetic adsorption unit to be powered off and controls the automated operation device to perform the disassembly and recycling of the protective cover plate, as well as controls the deployable load-bearing track system to retract into the first groove on the side wall of the dock.

[0037] The present invention also proposes a construction method for the above-described quick-release explosion-proof protective cover system, comprising the following steps:

[0038] Upon receiving a warning signal, the deployable load-bearing track system extends and locks.

[0039] The automated operation device descends along the unfolded, deployable load-bearing track system to the bottom of the dock, grabs the modular magnetic explosion-proof protective cover plate, and transports it to the designated height on the side wall of the dock for installation, until all protective cover plates are installed from top to bottom or from bottom to top.

[0040] When the electromagnetic adsorption units of all protective covers are energized, a strong magnetic adsorption force is generated, causing adjacent covers to connect tightly to form an explosion-proof cover protection system for the dock sidewalls; and

[0041] After receiving the warning cancellation signal, the power supply to the electromagnetic adsorption unit is cut off, and the magnetic connection between the protective covers is released.

[0042] The automated operation device then runs along the unfolded, deployable load-bearing track system to the position where the protective cover has been installed, disassembles it, and transports it back to the bottom of the dock.

[0043] After all protective covers have been removed and recycled, the deployable load-bearing track system retracts into the first groove on the side wall of the dock.

[0044] The advantages of this invention compared to existing technologies are: the blast-resistant protective cover system proposed in this invention can be deployed within 30 minutes, with a single cover deployment time of ≤3 minutes, enabling rapid response in wartime to provide protection for the dock. After the warning is lifted, it can also be quickly disassembled without affecting the dock's normal production operations. Specifically, it has at least the following practical effects:

[0045] In this invention, multiple modular magnetic blast-resistant protective covers can be flexibly combined and spliced ​​according to actual protection needs to form a large-area, continuous, and stable blast-resistant protective layer. In extreme situations such as explosion impacts, this protective layer can effectively disperse and absorb explosive energy, significantly improving the overall blast resistance of the dock.

[0046] In this invention, each modular magnetic explosion-proof protective cover is equipped with an electromagnetic adsorption unit on its edge. The electromagnetic adsorption unit built into the cover instantly generates a strong magnetic field force, realizing rapid rigid locking between the cover plates and ensuring that the joint area meets the explosion-proof sealing performance index.

[0047] In this invention, multiple deployable support tracks provide a good running track for the automated operation device, allowing it to move stably and efficiently along the dock sidewalls, thus improving operational efficiency. Furthermore, their structure directly forms the installation keel frame for the modular magnetic explosion-proof protective cover, reliably supporting and securing all the protective covers. This highly integrated design eliminates the need for separately designing and installing complex support frames for the protective covers, significantly simplifying the overall system structure, saving installation space and construction costs, and making the installation and disassembly of the protective covers more direct and efficient.

[0048] In this invention, the automated operation device is designed to operate on a deployable load-bearing track system. Upon warning, it can quickly grab the protective cover plate from the bottom of the dock and precisely transport it to a designated height for continuous installation. After the warning is lifted, it can be disassembled and transported back. This design greatly improves the dock's emergency response efficiency, enabling the rapid construction of a reliable explosion-proof cover plate protection system. High-precision operation ensures the installation quality of the protective cover plates, enhancing protective stability. Simultaneously, it achieves resource recycling, reduces labor costs and safety risks, and comprehensively improves the dock's ability to cope with emergencies and its operational efficiency.

[0049] In this invention, the central control system is communicatively connected to the deployable load-bearing track system, the automated operation device, and the electromagnetic adsorption unit. It is used to receive external signals and switch between "wartime" and "peacetime" modes accordingly. In the early warning state, the system automatically triggers and sequentially executes the deployment of the deployable load-bearing track, the installation of the modular magnetic explosion-proof protective cover, and the electromagnetic locking process of the electromagnetic adsorption unit. In the peacetime state, the system triggers the electromagnetic release, cover removal, and track recovery processes, thereby achieving automated operation of the entire system.

Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0072] 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 mechanical connection or an electrical connection; 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.

[0073] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.

[0074] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", 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 the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.

[0075] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0076] The implementation of the present invention will be described in detail below with reference to preferred embodiments.

[0077] like Figures 1 to 8 As shown, this invention proposes a quick-install and quick-release blast-resistant protective cover system for the sidewalls of large docks during wartime. This system solves the problem of rapid installation / disassembly of large coastal docks during wartime, provides multiple blast resistance capabilities (resistance to close-range explosions of 100kg-class aerial bombs), and does not affect peacetime production, thus meeting the needs of protection and rapid production conversion during wartime.

[0078] The explosion-proof protective cover system includes multiple modular magnetic explosion-proof protective covers 1, an deployable load-bearing track system, and at least one automated operation device 3.

[0079] Among them, multiple modular magnetic explosion-proof protective covers 1 are stored in the cover storage facility at the bottom of the dock. See also Figure 3 , Figure 4 Each modular magnetic explosion-proof protective cover 1 has a second groove 101 on its edge, and an electromagnetic adsorption unit 4 is provided in the groove.

[0080] The deployable load-bearing track system is installed on the dock sidewall 5 (concrete pool wall) and extends longitudinally along the sidewall to form a keel frame on the surface of the dock sidewall 5 for mounting and fixing multiple modular magnetic explosion-proof protective covers 1. When not in operation, the deployable load-bearing track system is stored in a pre-set first groove 501 in the dock sidewall 5. Upon triggering a warning signal, it extends from the first groove 501 and locks in place.

[0081] The first groove 501 pre-set in the dock sidewall 5 is used for storing the steel structure support of the deployable load-bearing rail in the non-operational state, achieving functional compatibility with daily ship operations. The specific dimensions of the first groove 501 are adapted to the specific structure of the deployable load-bearing rail system, suitable for completely embedding the deployable load-bearing rail system into the pre-set groove in the dock sidewall.

[0082] The automated operation device 3 is configured to operate on a deployable support rail system. Upon triggering a warning signal, the automated operation device 3 can pick up multiple modular magnetic blast-resistant protective covers 1 from the bottom of the dock and transport them to a designated height on the deployable support rail system for continuous installation. After the warning signal is lifted, the automated operation device 3 can disassemble the installed modular magnetic blast-resistant protective covers 1 and return them to the cover storage facility at the bottom of the dock.

[0083] Furthermore, once multiple modular magnetic explosion-proof protective covers 1 are installed in place, the electromagnetic adsorption unit 4 is activated, causing adjacent modular magnetic explosion-proof protective covers 1 to be attracted and connected to each other, forming an explosion-proof cover protection system 6 for the dock sidewall 5.

[0084] As is easily understood, the protective cover plates installed in this invention through a continuous laying method form a unified protective surface. Compared to individually installed cover plates, this integrated structure can more effectively disperse and withstand the forces of shock waves and debris generated by an explosion. Just as a solid wall is more resistant to external impacts than multiple individual bricks, continuously laid protective cover plates can provide more reliable and stable blast protection for docks, maximizing the safety of personnel, equipment, and facilities within the dock.

[0085] In one embodiment, the main structure of the dock has the following dimensions: length 500m and height 15m. Based on these dimensions, the dock pool wall protection area (dock sidewall) needs to be equipped with 420 modular magnetic explosion-proof protective covers 1.

[0086] In some embodiments, each modular magnetic explosion-proof protective cover 1 is a trapezoidal FRP reinforced composite material plate with specific geometric parameters of: upper base 4m × lower base 7m × ladder height 3m × plate thickness 0.2m. Multiple modular magnetic explosion-proof protective covers 1 are arranged in a staggered stacking layout in the storage state.

[0087] See Figure 3 , Figure 4Each modular magnetic explosion-proof protective cover 1 adopts a "sandwich" composite structure design, consisting of an inner and outer FRP layer 7 and a middle concrete layer 8. The specific layered structure is as follows: the outer layer is a 30mm thick FRP reinforced composite material layer, the middle layer is a 140mm thick ultra-high performance concrete core layer (compressive strength ≥150MPa), and the inner layer is a 30mm thick FRP reinforced composite material layer. The overall dimensional accuracy control standards for the cover are: top bottom 4000mm±2mm, bottom bottom 7000mm±2mm, step height 3000mm±2mm, and plate thickness 200mm±1mm.

[0088] In some embodiments, the outer surface of the modular magnetic explosion-proof protective cover 1 is uniformly provided with a plurality of third grooves 102, each of which is preferably a non-uniform quadrangular pyramidal groove structure. The third grooves 102 serve as explosion-proof grooves, achieving efficient dissipation of shock wave energy through structural deformation optimization. The inner surface of the modular magnetic explosion-proof protective cover 1 is pre-set with two sets of parallel positioning components, suitable for fixing at a predetermined installation position on the deployable load-bearing track system, ensuring structural stability after temporary installation.

[0089] As is easy to understand, the "inner layer" and "inner side" here refer to the side of the cover plate facing the dock structure when it is installed, while the "outer layer" and "outer side" refer to the side facing away from the dock structure and exposed to the external environment.

[0090] In some embodiments, each positioning component includes two spaced-apart convex positioning keys 103, and the space between the two convex positioning keys 103 is adapted to the size of the transverse support rod 202 of the deployable support track system described below, so as to snap and fix the modular magnetic explosion-proof protective cover 1 onto the transverse support rod 202.

[0091] In some embodiments, the cover storage facility is a pre-set storage space at the bottom of the dock pool, with structural parameters of: depth 1.5m, width 3m, and length 500m.

[0092] In this invention, the warehouse storage adopts a three-dimensional staggered stacking method, and flexible support is achieved through customized plastic partitions (Shore 85A hardness).

[0093] In some embodiments, the electromagnetic adsorption unit 4 includes a silicon steel sheet core, an electromagnetic winding, and a thermally conductive silicone potting layer. The silicon steel sheet core is a rectangular sheet and is arranged around the edge of each modular magnetic explosion-proof protective cover 1. Preferably, the silicon steel sheet core is tightly bonded to the second groove 101 opened at the edge of the protective cover by a high-strength adhesive. The electromagnetic winding is tightly wound around the outer peripheral surface of the silicon steel sheet core, suitable for generating a magnetic field by energizing it; the thermally conductive silicone potting layer completely fills the second groove 101, covering all surfaces of the electromagnetic winding and the silicon steel sheet core exposed to air.

[0094] In this embodiment, after multiple modular magnetic explosion-proof protective covers 1 are installed in place, the electromagnetic winding of the electromagnetic adsorption unit 4 is energized through the control circuit. The electromagnetic winding generates a magnetic field, which is enhanced and guided by the silicon steel core, forming a strong magnetic field between the electromagnetic adsorption units 4 of adjacent modular magnetic explosion-proof protective covers 1. Because the magnetic poles of the magnetic fields generated by the electromagnetic adsorption units 4 on adjacent covers attract each other (the N pole of one unit is opposite to the S pole of another unit), this strong attraction will instantly attract and connect the adjacent modular magnetic explosion-proof protective covers 1 to each other, achieving rapid rigid locking between the covers, thereby forming the explosion-proof cover protection system 6 of the dock sidewall 5, effectively resisting external explosion impacts and other dangers.

[0095] In one specific embodiment, each modular magnetic explosion-proof protective cover 1 has a 60mm×60mm rectangular groove around its perimeter. A customized integrated electromagnetic adsorption unit is built into this groove. This unit consists of a 0.35mm thick silicon steel core, a high-temperature resistant electromagnetic winding, and a thermally conductive silicone potting layer. It has a rated operating voltage of 220V and an adsorption force per unit area ≥150kN / m². The electromagnetic adsorption bonding surfaces between adjacent covers are precision ground, with a flatness tolerance ≤0.05mm and a surface roughness parameter Ra≤1.6μm.

[0096] In this invention, the modular magnetic explosion-proof protective cover 1 adopts a modular design, which facilitates storage, transportation and installation, and also makes maintenance and replacement convenient.

[0097] After deployment, the deployable load-bearing track system settles into its base on the bottom of the dock pool. (See also...) Figure 2 The deployable support rail system includes multiple deployable support rails 2, which are uniformly installed at predetermined distances on the surface of the dock sidewall 5.

[0098] In this invention, multiple deployable support tracks 2 provide a good running track for the automated operation device 3, allowing the device to move stably and efficiently on the dock sidewall, thus improving operational efficiency. Furthermore, their own structure directly constitutes the installation keel frame for the modular magnetic explosion-proof protective cover 1, reliably supporting and fixing all the protective covers. This highly integrated design eliminates the need for separately designing and installing complex support frames for the protective covers, significantly simplifying the overall system structure, saving installation space and construction costs, and making the installation and disassembly process of the protective covers more direct and efficient.

[0099] Each deployable support track 2 consists of a vertical support rod 201, a horizontal support rod 202, and a hydraulic support mechanism 203. Two vertical support rods 201 are provided, positioned parallel to the first groove 501 outside the dock sidewall 5. Multiple horizontal support rods 202 are horizontally connected between the two vertical support rods 201 at predetermined height intervals, forming a support frame together with the vertical support rods 201. The horizontal support rods 202 are used to install and fix the modular magnetic explosion-proof protective cover 1. The hydraulic support mechanism 203 is installed in the first groove 501 of the dock sidewall 5 and connected to the vertical support rods 201. It drives the support frame formed by the vertical support rods 201 and the horizontal support rods 202 to move between being contained within the first groove 501 and extending outwards and locking to the dock sidewall 5 at a predetermined distance.

[0100] In some embodiments, the hydraulic support mechanism 203 includes multiple pairs of hydraulic support tubes, which are evenly arranged in the first groove 501 along the height direction of the vertical support rod 201. One end of each pair of hydraulic support tubes is connected to the dock sidewall 5, and the other end is hinged to the vertical support rod 201. Each pair of hydraulic support tubes is adapted to extend under hydraulic pressure upon receiving a warning signal, pushing the vertical support rod 201 outward along a preset trajectory, and mechanically locking itself via a hydraulic lock after reaching its maximum stroke.

[0101] It should be clarified that the hydraulic support and locking principle of each pair of hydraulic support tubes is existing technology. During hydraulic support, pressurized hydraulic oil is delivered into the tube by the hydraulic system, pushing the piston to extend the tube and causing the vertical support rod 201 to extend. After reaching the maximum stroke, the existing hydraulic lock controls the return flow of hydraulic oil to lock the piston position and achieve mechanical locking.

[0102] As is easy to understand, the maximum stroke refers to the limit length that each pair of hydraulic support tubes can extend under hydraulic pressure.

[0103] In some embodiments, each vertical support rod 201 is an H-beam, and the outer flange surface of the H-beam forms the travel track of the automated operating device. The surface of the H-beam is hot-dip galvanized (zinc layer thickness ≥ 85 μm) and formed with a functional surface of a specific friction coefficient by precision CNC machining, providing suitable friction conditions and guiding reference for the movement of the automated operating device 3.

[0104] In some embodiments, each transverse support bar is a square steel tube.

[0105] In one specific embodiment, see further. Figure 2 Each deployable support track 2 consists of two high-strength H-beam vertical bars (cross-section specifications: H200mm×200mm×8mm×12mm), five square steel tubes (cross-section specifications: 100mm×100mm), and ten pairs of hydraulic support round tubes (cross-section specifications: Φ169×8mm). The spacing between the double round tube supports is 1m, the horizontal spacing between the H-beam vertical bars is 3m, and the vertical spacing between the square steel tubes is 3m. The hydraulic support round tubes have pre-installed hydraulic transmission pipelines, which connect to the hydraulic power and signal transmission links of the central control system described below through pre-embedded hydraulic lines within the pool wall structure (dock sidewall).

[0106] Each deployable support rail 2 is retracted into a pre-set 0.4m deep first groove 501 in the side wall of the dock 5 when not in operation. After retraction, its outer surface remains flush with the decorative surface of the pool wall to ensure no structural interference with the passage of ships. When receiving a warning command from the system (system response delay ≤ 15 seconds), the hydraulic power unit embedded in the pool wall structure drives the support tube at a working pressure of 25MPa, causing the support frame to extend outward at a uniform speed along a preset trajectory. The extension stroke is 800mm ± 5mm, and the extension speed is controlled at 50mm / s to ensure that the action process meets the requirements of stability and no impact load.

[0107] See Figure 2 Each deployable bearing track 2 is equipped with two automated operating devices 3. The two automated operating devices 3 work together to synchronously support a single modular magnetic explosion-proof protective cover plate 1.

[0108] See Figure 8 Each automated operating device 3 includes a walking mechanism 301, a robotic arm 302, and an end gripper 303. The walking mechanism 301 is adapted to be mounted on the vertical support rod 201 and is used to drive the automated operating device 2 to slide up and down on the walking track. The robotic arm 302 is a multi-section robotic arm that can rotate and extend freely. One end of the robotic arm is fixedly connected to the walking mechanism 301, and the other end is connected to the end gripper 303. The end gripper is located at the end of the robotic arm 302 and can rotate freely. It is used to grasp and lock the modular magnetic explosion-proof protective cover 1.

[0109] In this invention, the connection nodes between the robotic arm 302, the walking mechanism 301, and the end gripper 303 all adopt an omnidirectional rotary hinge structure to achieve multi-degree-of-freedom motion.

[0110] When not in operation, the automated operation device 3 is parked at the top of the vertical support rod 201, with its robotic arm 302 and end gripper 303 in a retracted state.

[0111] In some embodiments, the robotic arm 302 has a maximum extension length of 2m and omnidirectional rotational freedom; the end gripper 303 can achieve multi-dimensional rotational movement and can mechanically lock with the third groove 102 built into the protective cover. The main frame of the automated operation device is integrally formed from aerospace aluminum alloy material, with a self-weight parameter ≤800kg and a rated load capacity of 1500kg.

[0112] In this invention, after the support frame of the deployable bearing track system is positioned and calibrated, the automated operation device 3 is activated. The automated operation device 3 descends along the upper guide rail of the vertical support rod 201 to the bottom working position, and then extends the multi-degree-of-freedom end gripper 303, so that the three sets of angle gripping mechanisms are embedded into the preset connection interface (third groove) of the protective cover plate, completing the locking gripping operation. Subsequently, the two automated operation devices 3 working in concert simultaneously carry a single protective cover plate, and after completing the cover plate posture flipping action, they install the cover plates precisely to the preset work positions in a top-down order (the deployment cycle of a single cover plate is ≤3 minutes). When the cover plate reaches the designated installation coordinates, the two sets of positioning components preset on its back engage and lock with the horizontal bearing rod 202, completing the temporary positioning of the protective cover plate; after the automated operation device 3 completes the disengagement action, it descends along the track to the bottom and performs the installation operation of the second protective cover plate in the same operation logic, until the installation of all cover plates is completed in a top-down sequence.

[0113] In some embodiments, the walking mechanism 301 includes a C-shaped walking trolley, guide wheels, and a drive assembly. The C-shaped walking trolley is snapped onto the vertical support rod 201; the guide wheels are installed in pairs on the inner side of the C-shaped walking trolley and contact the surface of the vertical support rod; the drive assembly is installed on the C-shaped walking trolley and is used to drive the C-shaped walking trolley to slide up and down along the vertical support rod.

[0114] In some embodiments, the quick-release explosion-proof protective cover system also includes a central control system. This system is communicatively connected to the deployable load-bearing track system, the automated operation device 3, and the electromagnetic adsorption unit 4. It is used to receive external signals and switch between "wartime-peacetime" modes accordingly. In the early warning state, the system automatically triggers and sequentially executes the deployment of the deployable load-bearing track 2, the installation of the modular magnetic explosion-proof protective cover 1, and the electromagnetic locking process of the electromagnetic adsorption unit 4. In the peacetime state, the system triggers the electromagnetic release, cover removal, and track recovery process, thereby achieving automated operation of the entire system.

[0115] Specifically, the central control system is adapted to perform the following operations upon receiving a warning signal:

[0116] Control the deployment and locking of the deployable load-bearing track system;

[0117] The automated operation device 3 is controlled to perform the installation of the modular magnetic explosion-proof protective cover 1, and after the installation is completed, the electromagnetic adsorption unit 4 is powered on to form the explosion-proof cover protection system 6 of the dock sidewall 5.

[0118] And upon receiving the warning cancellation signal, perform the following operations:

[0119] The electromagnetic adsorption unit 4 is powered off and the automated operation device 3 is controlled to perform the disassembly and recycling of the modular magnetic explosion-proof protective cover 1 and to control the unfoldable load-bearing track system to retract into the first groove 501 of the dock side wall 5.

[0120] This invention employs a "wartime-peacetime" dual-mode modular switching technology. Upon receiving a typhoon / air raid warning signal, the central control system triggers a rapid protective deployment process: after the deployable support track unfolds and locks in place, the automated operation device retrieves modular magnetic blast-resistant protective covers from the dock's bottom storage unit and transports them to the corresponding installation position on the deployable support track (speed 1.2 m / min). The electromagnetic adsorption units between the covers activate to form a blast-resistant cover protection system for the main structure of the pool wall. When the warning signal is lifted, the power supply is cut off to release the electromagnetic adsorption force between the covers, and the automated operation device, according to a preset program, returns each modular magnetic blast-resistant protective cover to the dock's bottom storage unit. After the cover retrieval operation is completed, the vertical support rod, driven by a hydraulic support mechanism, retracts and returns to its preset groove (first groove) in the pool wall; the automated operation device simultaneously resets to its parking position at the top of the vertical support rod. The entire deployment time for this rapid disassembly and assembly blast-resistant protective cover system is ≤30 minutes.

[0121] In one specific embodiment, a modular dual-mode switching technology of "wartime-peacetime" is applied. After receiving an early warning signal, the central control system executes operations according to the following programmed procedure:

[0122] Start command issued (response time ≤ 5 seconds);

[0123] Deployable load-bearing rail extension and hydraulic locking (operation cycle ≤ 3 minutes).

[0124] Start-up and operation of automated operation equipment and scheduling of cover plate outbound (single plate interval cycle ≤ 2.5 minutes);

[0125] Automated operation equipment performs installation operations (single block operation time ≤ 1 minute);

[0126] Radar detection and electromagnetic adsorption connection (single block processing time ≤ 1 minute);

[0127] System overall function self-test (test cycle ≤ 2 minutes).

[0128] The entire process employs a system-level real-time monitoring mechanism. Key operational nodes are equipped with video monitoring subsystems and multi-parameter sensor networks (including vibration sensors, stress sensors, and displacement sensors) to achieve real-time acquisition and feedback of status data. Once the warning signal is cleared, the system executes the disassembly operation in reverse order: after the electromagnetic adsorption unit is de-energized, the automated operation device operates according to the reverse operation logic, ensuring the orderly disassembly and recovery of the protective cover. Through the central control system and automated operation device, the deployment and disassembly of the protective cover are automated, reducing manual operation and improving efficiency and accuracy.

[0129] In some embodiments, the quick-release explosion-proof protective cover system also includes a three-dimensional scanning system suitable for detecting the flatness of the surface of the installed modular magnetic explosion-proof protective cover. Specifically, after all the modular magnetic explosion-proof protective covers 1 have been deployed, the central control system activates the millimeter-wave radar three-dimensional scanning system to detect the flatness of the cover surface. When the detection data confirms that it meets the preset accuracy threshold, the backup energy storage power supply (pre-embedded in the pool wall and connected through pre-embedded pipelines inside the pool wall) is activated to provide power. The electromagnetic adsorption unit 4 built into the cover instantly generates a strong magnetic field force to achieve rapid rigid locking between the covers, ensuring that the joint area meets the explosion-proof sealing performance index.

[0130] In this embodiment, the backup power supply uses a lithium iron phosphate battery pack (nominal voltage 400V, capacity 500Ah), which can switch power supply within 10 seconds after the main power supply (located on the bottom surface of the pool, which can be activated if destroyed in wartime) is cut off. After power-on, the electromagnetic adsorption unit reaches 90% of the rated adsorption force within 0.5 seconds and completes 100% locking within 2 seconds.

[0131] In one specific embodiment, after the modular magnetic explosion-proof protective cover 1 is deployed, a millimeter-wave radar system (operating frequency 77GHz, detection accuracy 0.01mm) is activated to perform a full-coverage scan of the protective cover surface. The millimeter-wave radar system automatically generates a three-dimensional point cloud map, which is compared with the design model. When any deviation at any point exceeds 0.3mm, an automatic correction program is triggered. The cover's hydraulic fine-tuning device (stroke ±5mm) is activated to ensure that the flatness meets the standard.

[0132] The present invention also proposes a construction method for the above-mentioned quick-release explosion-proof protective cover system, comprising the following steps:

[0133] Upon receiving the warning signal, the central control system issues a start command.

[0134] Deployable load-bearing track system with extension and locking;

[0135] The automated operation device 3 is started and descends along the vertical support rod of the unfolded expandable bearing track 2 to the bottom of the dock to grab the modular magnetic explosion-proof protective cover 1 and transport it to the designated height of the dock side wall 5 for installation until all protective covers are installed from top to bottom or from bottom to top.

[0136] When the electromagnetic adsorption units of all protective covers are energized, a strong magnetic adsorption force is generated, which tightly connects adjacent covers to form an explosion-proof cover protection system for the dock sidewall.

[0137] And after receiving the warning cancellation signal, the central control system cuts off the power supply to the electromagnetic adsorption unit 4, and releases the magnetic connection between the protective covers, that is, releases the electromagnetic adsorption clamping force between the covers.

[0138] The automated operation device 3 is restarted and runs along the unfolded, deployable load-bearing track system to the position where the protective cover has been installed, disassembles it, and transports it back to the bottom of the dock.

[0139] After all protective covers have been removed and recycled, the deployable load-bearing track system 3 retracts into the first groove 501 on the side wall of the dock.

[0140] In some embodiments, after all protective covers are installed, the surface flatness of all installed protective covers needs to be tested. When the test data is confirmed to meet the preset accuracy threshold, the electromagnetic adsorption unit of all protective covers is energized to generate a strong magnetic adsorption force, so that adjacent covers are tightly connected to form an explosion-proof cover protection system for the dock sidewall. If it is not flat, the fine-tuning program is started until the flatness meets the preset accuracy threshold.

[0141] The blast-resistant protective cover system proposed in this invention, which can be quickly installed and removed, undergoes rigorous performance testing. In a simulated close-range explosion test of a 100kg bomb (detonated 5m from the cover surface), the modular magnetic blast-resistant protective cover exhibits a maximum deformation of ≤8mm, a seam opening of ≤0.2mm, and stable operation of the electromagnetic adsorption unit. The actual testing time from receiving the warning signal to completing full protection deployment is ≤30 minutes.

[0142] The blast-resistant protective cover system proposed in this invention can be deployed within 30 minutes, with a single cover deployment time of ≤3 minutes. It enables rapid response during wartime, providing protection for the dock. After the warning is lifted, it can also be quickly disassembled without affecting the dock's normal production operations.

[0143] It will be readily understood by those skilled in the art that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0144] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
