[0001] This utility model belongs to the technical field of IPC classification H02G1 / 00, which is dedicated to methods or equipment for installing, maintaining, repairing or dismantling cables or wires. In particular, it relates to a structural improvement technology for a protective cover device for the surface of cable facilities, which is applicable to cable laying by cranes in container terminals. Background Technology

[0002] Currently, in container terminal operations, power supply systems require ground-level cable trenches for power transmission. (See attached...) Figure 1 As shown, the crane cable protection cover is an important component to ensure the normal operation of the cable.

[0003] Patent application 202221589971.0 discloses a protective cover for a ship cable tray, relating to the field of cable trays. It includes a housing, with fixing rods on both sides of the housing. One end of each fixing rod has a groove, and a movable block is rotatably disposed in the groove. The support point of the movable block is located at the bottom of the groove. An inner shell is disposed inside the housing, and a clamping plate is elastically connected inside the inner shell. An array of cable grooves is disposed on one side of the clamping plate.

[0004] Patent application 202311096317.5 relates to the field of cable trench cover technology, specifically to cable trench covers and their installation methods. The cover includes a cover body, a groove and a rectangular protrusion on the cover body, a support plate slidably mounted on the cover body, and a friction platform (multiple sets slidably mounted on the cover body, the friction platform being frustoconical). The cover body has an inlet and an outlet, and an air bladder is located inside the cover body. The installation method for the cable trench cover includes: S1, installing the friction platform on the cover body via a fixing plate and connecting it to the air bladder; placing a float on the friction platform and installing a limiting block; connecting the support plate to the float; S2, digging the cable trench and pre-drilling drainage trenches on both sides of the cable trench; S3, placing multiple sets of cover bodies on the cable trench and fitting them together, with the outlets facing the pre-drilled drainage trenches.

[0005] The following defects exist:

[0006] 1) Risk of mechanical damage: The single-layer structure has low strength. When dock vehicles such as forklifts and container trucks pass by, they are easy to run over the cable trough cover, causing the cover to deform or break, which in turn damages the cable.

[0007] 2) Environmental corrosion problems: Salt spray and humid environment at the dock accelerate the corrosion of the cover plate and shorten its service life.

[0008] 3) Low maintenance efficiency: Traditional cover plates require frequent manual cleaning of sand, oil and other foreign objects, and maintenance requires stopping the machine, which affects the efficiency of operation.

[0009] 4) Lack of safety monitoring: The lack of real-time monitoring of the cover plate status makes it difficult to detect abnormalities such as deformation and displacement in a timely manner, affecting rapid maintenance. Utility Model Content

[0010] This utility model designs a composite optimized clean and monitorable protective cover for cable splicing of container terminal cranes. By designing a composite layer structure for the protective cover shell and improving the structure for convenient multi-functional installation and application, it solves the defects of existing technologies and has significant advantages in terms of protective performance, installation and maintenance, intelligent monitoring and cost-effectiveness, effectively solving many problems existing in existing cable protection covers.

[0011] Therefore, this utility model provides a composite optimized cleanable and monitorable protective cover for cable splicing of container terminal cranes, comprising a fixed frame, a top plate, and a hinged door; the fixed frame, top plate, and hinged door are multi-layered composite structures; the fixed frame has a frame groove in the middle; the top plate has a slotted opening at least partially on the front side; the top plate is fixed to the top surface of the fixed frame, and the hinged door is installed on the partially hollowed-out opening of the top plate; a monitoring module is installed on the fixed frame, top plate, or hinged door. A support frame is fixed to the bottom of the hinged door.

[0012] The fixed frame, top plate, and flip door form a three-layer composite structure, consisting of a surface cleaning layer, an outer shell, and a sandwich buffer layer, from the outside in. Specifically, the surface cleaning layer is a self-cleaning nano-coating; and the outer shell is a double-layer structure consisting of a steel core reinforced with rubber or an embedded copper-plated steel core-polyamide composite mesh.

[0013] The top plate surface of the port rear side and the left and right side edges is surrounded by a U-shaped fixed guide strip.

[0014] The entire top plate slopes towards the front side. Alternatively, the top plate has a ridge-like ridge in the longitudinal middle, i.e., behind the flip-up door, with the top plate surface sloping towards the front and rear sides respectively with the central ridge as the ridge.

[0015] At least two folding doors are hingedly installed on the long, slotted opening on the front side of the top plate; the rear edge of the folding doors is hinged to the rear edge of the opening.

[0016] The monitoring module includes a fiber optic grating sensor and an image recognition module.

[0017] Furthermore, to achieve the above objectives, this utility model is configured as follows:

[0018] In particular, the top plate has side holes on its front and rear edges.

[0019] In particular, a support frame is fixed around the bottom of the folding door, and at least part of the door panel extends 301mm beyond the support frame, fitting snugly within the mounting opening. A locking pin is installed on the bottom front edge of the folding door. A hanging ring is installed on the bottom surface of the folding door. A sign is placed in the center of the folding door surface. A groove is cut into a portion of the rear edge of the support frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Superior protective performance: The protective cover itself also has vibration damping properties, and its mechanical strength and weather resistance are greatly improved. It can effectively resist sea winds, salt spray, mechanical impacts, and sun and rain, greatly extending the service life of the cable. It can effectively absorb impact forces when subjected to mechanical collisions, protecting the cable from damage.

[0022] Easy installation: The multi-section splicing design facilitates installation and disassembly. Sealing strips at the joints enhance waterproof and dustproof performance and reduce installation difficulty. Combined with a specially designed fixing device, it ensures the protective cover is securely installed on the cable, preventing loosening or detachment during crane operation, thus reducing installation time and labor costs.

[0023] Low maintenance cost: The self-cleaning surface of the protective cover effectively reduces the adhesion of dust and dirt, reducing the difficulty of daily maintenance and eliminating the need for frequent cleaning, thereby reducing maintenance costs.

[0024] Monitoring and Early Warning: The integrated monitoring module can monitor the temperature, humidity, and potential damage of the protective cover in real time, and transmit the data to the monitoring center for remote monitoring and early warning. This function helps to promptly identify potential problems, take preventative measures, avoid electrical faults, and improve the safety and reliability of crane operation.

[0025] High cost-effectiveness: With its superior protective performance, it reduces the frequency of cable replacement and repair, lowering maintenance costs.

Detailed Implementation

[0034] It should be noted that:

[0035] In the description of this utility model, unless otherwise expressly specified and limited, the terms "comprising" and "having," and any variations thereof, are intended to cover other possible options under the same logic not listed. For example, a process, method, system, product, or device comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or device.

[0036] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0037] This invention reveals that the cable protection covers currently used on container terminal cranes suffer from defects such as poor protective performance, high maintenance costs, lack of intelligent monitoring, and inconvenient installation. Firstly, the cover shells are typically simple, monolithic structures made of a single metal or non-metal material, lacking buffer layers and self-cleaning coatings. This compromises the cover's structural strength, vibration damping, and surface corrosion resistance; in the complex environment of a terminal, they are unable to withstand sea wind erosion, salt spray corrosion, mechanical impacts, and exposure to sun and rain. Secondly, the lack of effective sealing and securing designs between multiple cable protection covers during installation contributes to the problem. Thirdly, any abnormalities caused by these defects cannot be detected promptly.

[0038] The principle of this utility model is to design a novel multi-layer composite shell structure that combines buffering and shock absorption, surface corrosion resistance, and protective strength. Furthermore, this structure is used to create a splicable protective cover that is easy to install and apply.

[0039] As attached Figure 2 As shown, this utility model includes: a fixed frame 1, a top plate 2, and a flip door 3; the fixed frame 1, top plate 2, and flip door 3 are a multi-layer composite structure; the fixed frame 1 has a frame groove 101 in the middle; the top plate 2 has a groove-shaped mounting opening 201 partially opened longitudinally on its front side; the top plate 2 is fixed to the top surface of the fixed frame 1, and the flip door 3 is installed on the partially hollowed-out mounting opening 201 of the top plate 2; a monitoring module 10 is installed on the fixed frame 1, the top plate 2, or the flip door 3. A support frame 301 is fixed to the bottom of the flip door 3.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Example 1: As shown in the attached document Figure 3 As shown, both the fixed frame 1 and the top plate 2 adopt a rectangular structure design. At least two folding doors 3 are installed on the long slot-shaped hollow mounting opening 201 on the front side of the top plate 2, which are hinged together. The rear edge of the folding doors 3 is hinged to the rear edge of the mounting opening 201 via hinges 6.

[0042] As described above, the fixed frame 1, top plate 2, and flip door 3 form a three-layer composite structure, consisting of a surface cleaning layer A, an outer shell B, and a sandwich buffer layer C, from the outside in. Furthermore, the surface cleaning layer A is a self-cleaning nano-coating, and the sandwich buffer layer C is a vibration-damping sandwich filling buffer layer.

[0043] As described above, a U-shaped guide strip 4 is fixed around the surface of the top plate 2 on the rear side and left and right sides of the loading port 201. In particular, the top plate 2 is inclined towards the front slope as a whole. Alternatively, the longitudinal middle of the top plate 2, i.e., the rear side of the flip door 3, has a ridge-like ridge, keeping the surface of the top plate 2 inclined towards the front and rear slopes respectively with the central ridge as the ridge. The slope structure of the top plate 2, combined with the structure of the guide strip 4, ensures effective and rapid drainage of rainwater from the surface of the top plate 2, preventing excessive flow through the flip door 3 or water accumulation on the surface of the flip door 3. This, combined with the ≥2% slope of the wharf, enables rainwater self-drainage and avoids water accumulation and corrosion.

[0044] In this embodiment, the main structure of the protective cover, namely the fixing frame 1, the top plate 2, and the flip door 3, adopts a composite structure design, combining flexible and rigid composite functions. The main structure of the protective cover, namely the fixing frame 1, the top plate 2, and the flip door 3, uses high-strength, corrosion-resistant composite materials such as glass fiber reinforced plastic (FRP) as the main material, and is molded into a multi-layer composite structure.

[0045] In particular, the surface cleaning layer A is applied to the fixed frame 1, top plate 2, or flip door 3. This surface cleaning layer A employs a superhydrophobic self-cleaning coating, optimized for superhydrophobic surface enhancement. Based on an aluminum-based micro / nano structure prepared using laser direct writing technology, it exhibits a static contact angle >150° and a contact angle hysteresis <5°, achieving rainwater self-cleaning and resistance to salt spray corrosion. The specific coating process combines the sol-gel method with laser interferometry to construct a dual-scale micro / nano structure on an aluminum substrate, with a linear interference fringe period of 7.0 μm, achieving a 99% particulate contaminant removal efficiency. Specifically, surface cleaning layer A utilizes a self-cleaning nano-coating to enhance durability. This is achieved by introducing porous SiO2 nanoparticles through a layer-by-layer self-assembly method, enhancing coating adhesion and achieving wear resistance of >250,000 cycles, suitable for high-frequency vehicle traffic at the dock. Rainwater self-cleaning efficiency reaches 99% for particulate removal. Simultaneously, it exhibits greater than 10 years of maintenance-free corrosion resistance in neutral salt spray tests. Self-cleaning test: 10 μL water droplets remove manganese oxide particles with an efficiency ≥95%.

[0046] In particular, the middle layer between the fixed frame 1, top plate 2, and hinged door 3 provides the supporting strength of the outer shell B. Outer shell B is made of high-strength, corrosion-resistant composite materials such as glass fiber reinforced plastic (FRP). Through optimized formulation and molding process, this material possesses excellent mechanical strength and weather resistance, effectively resisting sea wind erosion, salt spray corrosion, and sun and rain exposure, protecting the internal cables and extending their service life. Alternatively, outer shell B can be made of steel-core reinforced rubber covered or embedded with a copper-plated steel core-polyamide composite mesh; wherein, the steel-core reinforced rubber is an SBR / steel core / nylon composite structure, providing a withstand capability of 400 N / cm². 2With lateral stiffness and 90° opening / closing angle, and longitudinal elasticity, it can withstand vehicle crushing and cable maintenance. The copper-plated steel core and polyamide composite mesh enhance tear resistance, with a tear strength >720kN / m, preventing cover breakage. The main structure of the protective cover—fixed frame 1, top plate 2, and hinged door 3—has a load-bearing capacity of 400N / cm². 2 It far surpasses existing products.

[0047] In particular, the inner core layer of the fixed frame 1, top plate 2, and flip door 3 is a sandwich buffer layer C. The sandwich buffer layer C acts as a buffer layer, with polyurethane foam material added inside. When the protective cover is subjected to mechanical impact, the buffer layer can effectively absorb the impact force, reduce damage to the cable, and play a crucial role in protecting the cable.

[0048] In this embodiment, the main structure of the protective cover, namely the fixing frame 1 and the top plate 2, is designed with a special fixing device, including a frame groove 101, a side hole 202, a support frame 301, and a slot 303, for securely installing the protective cover onto the cable. During crane operation, this device can prevent the protective cover from loosening or falling off, ensuring that the protective cover always tightly wraps the cable and continuously plays a protective role.

[0049] In this embodiment, the monitoring module 10 includes a fiber Bragg grating sensor and an image recognition module. It can monitor the temperature, humidity, and any damage to the protective cover in real time. The module transmits the collected data to the monitoring center, enabling remote monitoring and early warning of the cable protection cover. Once an abnormality is detected, such as excessively high temperature, excessive humidity, or damage, the monitoring center receives the information promptly, allowing staff to take swift action to prevent the fault from escalating and ensure the safe and stable operation of the crane cable. The fault identification accuracy is ≥98%, and the response time is <1 second.

[0050] Fiber Bragg grating sensor: embedded in fixed frame 1, top plate 2 or flip door 3, real-time monitoring accuracy ±1με strain and temperature change range -30℃~+80℃, and early warning of overload or thermal deformation.

[0051] Image recognition module: Industrial cameras are deployed on both sides of the cable trough. Combined with the YOLOv8 model deep learning algorithm, the camera identifies abnormalities such as displacement of the fixed frame 1, top plate 2 or flip door 3, and intrusion of foreign objects, triggering an alarm and locating the fault point.

[0052] In this embodiment, the protective cover adopts a multi-segment splicing design. The fixing frame 1, top plate 2, and hinged door 3 are assembled from one or more individual units. The segments are connected by sealing strips at the joints, facilitating installation and disassembly. During installation, the segments can be flexibly spliced ​​according to the cable length, reducing installation difficulty; during disassembly, if a segment is damaged, the entire structure does not need to be replaced, reducing maintenance costs. The sealing strips enhance waterproof and dustproof performance, preventing moisture and dust from entering the protective cover and avoiding damage to the cable. (See attached...) Figure 4 As shown, the protective covers of two adjacent units are tightly installed by pressing the sealing strip 7 together with the longitudinal edge of the top plate 2.

[0053] In this embodiment, the bottom edge of the top plate 2 is designed to prevent theft between the cable trench 8 or other installation base, including fixing with stainless steel rivets and prefabricated pressure strips to prevent unauthorized disassembly.

[0054] The implementation principle of this embodiment is as follows: (see attached) Figure 5 As shown, cable 9 is laid in cable trench 8. First, a fixing frame 1 is clamped onto the edge of cable trench 8. The fixing frame 1 has a frame groove 101 in the middle. The edge of the top plate 2 is pressed onto the top of the fixing frame 1 by fixing screws 5. The top plate 2 has a hollowed-out mounting opening 201. Cable 9 or lead wires are connected and laid in the frame groove 101. The mounting opening 201 can expose and allow for cable 9 connection and debugging operations. Support frame 301 is fixed around the bottom surface of the flip door 3. A partial edge of the outer side of the flip door 3 extends out of the support frame 301 and fits into the edge of the mounting opening 201. The front and rear edges of the top plate 2 are fixed to the edge of cable trench 8 through side holes 202. A slot 303 is opened on the rear partial edge of the support frame 301. The slot 303 can be used to clamp the cable 9 lead wire. The locking pin 304 installed on the bottom front edge of the flip door 3 can be inserted and pulled to open and close the flip door 3. A hanging ring 302 installed on the bottom surface of the hinged door 3 allows for easy manual operation to open and close the hinged door 3. A label 305 is installed in the center of the surface of the hinged door 3 to identify the parameters, functions, and connection information of the cable 9 laid inside the protective cover. A partially open surrounding guide strip 4, particularly on the outer side of the U-shaped guide strip 4, is provided around the mounting surface of the hinged door 3 on the top plate 2 to prevent water accumulation on the surface of the hinged door 3. It meets the requirements for equipment protection level (IP65) in GB / T 1835-2023 "Technical Requirements for Corner Fittings of Series 1 Containers". It also meets the requirements for environmental adaptability from -30℃ to +80℃ in JT / T 1172.2-2023 "Technical Requirements and Test Methods for Series 2 Containers".

[0055] Example 2: The main structure of the protective cover, namely the fixing frame 1, the top plate 2, and the flip door 3, is manufactured as follows: aluminum substrate laser processing (DLW+DLIP dual process) → sol-gel coating spraying, curing at 120℃ → rubber layer vulcanization at 170℃ and 15MPa → monitoring module 10 sensor embedding and packaging.

[0056] Example 3: In the container terminal operating environment, when the crane is running, the cable protection cover is firmly fixed to the cable 9 by a fixing device. The main structure of the cover plate, namely the fixing frame 1, the top plate 2, and the hinged door 3, is made of materials with high strength and corrosion resistance, resisting the erosion of external factors such as sea wind, salt spray, mechanical impact, and sun and rain. When a mechanical impact occurs, the buffer layer absorbs the impact force, protecting the cable 9 from damage. The surface cleaning layer A, namely the self-cleaning nano-coating, makes it difficult for dust and dirt to adhere to the surface of the protection cover, maintaining its cleanliness. The monitoring module 10 continuously monitors the status of the protection cover and transmits the data to the monitoring center to promptly detect and handle potential problems, ensuring the normal operation of the entire cable system.

[0057] In this embodiment of the invention, a field trial was conducted at a cooperating container terminal. Multiple cranes were selected, and both this product and existing ordinary cable protection covers were installed for comparison. The operation of the two types of covers was observed and recorded over a certain period. The results showed that after prolonged exposure to sea winds, salt spray, and mechanical impacts, the crane cables equipped with this product showed no significant damage to the protection covers, and the cables operated normally. The intelligent monitoring module accurately transmitted data without any false alarms or omissions, and the monitoring center could promptly grasp the status of the protection covers. In contrast, some crane cables equipped with existing ordinary protection covers showed signs of aging and damage, leading to short circuits in the cables, affecting crane operations, and the status of the protection covers could not be monitored in real time.

[0058] In this embodiment of the utility model, compared with existing ordinary cable protection covers, the existing protective covers are made of ordinary materials and lack splicing design, buffer layer, self-cleaning coating and intelligent monitoring module. Under the same dock environment, existing ordinary protective covers age quickly and need to be replaced frequently; installation and disassembly are inconvenient, increasing maintenance costs and downtime; they cannot effectively protect cables and are prone to electrical faults; and the status of the protective cover cannot be monitored in real time, making it difficult to detect potential problems in time. All of these highlight the advantages of this product.

[0059] Based on the embodiments of this utility model described above, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this utility model.
