[0002] The technical field of this invention is anti-icing device for hydraulic metal structure gates, which is mainly used for de-icing and anti-freezing of embedded parts of gates in reservoirs, dams and hydropower stations in cold regions to ensure normal opening and closing of the gates.

[0003] Existing gate embedded anti-freezing devices mostly use heating cables to be directly laid or have simple fixed structures, which have obvious defects: the heating cables are mostly fixed installations and cannot be pulled out and disassembled. Once a part is damaged, the embedded part must be removed and the damaged part replaced or the entire heating cable must be replaced, which is difficult to maintain, has a long cycle, and is costly.

[0004] Meanwhile, traditional devices are mostly integral structures that cannot be segmented and spliced. On-site installation requires complex tools and professional procedures, resulting in low construction efficiency and difficulty in meeting the rapid laying needs of long-distance, large-area embedded heating areas. Summary of the Invention

[0015] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0016] Reference Figure 1-8 This invention discloses a quick-connect heating cable anti-freezing module, which adopts an embedded modular and non-standard customized dual design. It is specifically developed for the embedded parts and side rails of arc gates and planar gates of hydraulic metal structures such as reservoirs, hydropower stations, and water conservancy hubs in cold regions, which are prone to icing. The core components include an embedded part box 6, an inner movable box 2, a heating mechanism, a quick-connect splicing structure, and a sealing and fixing structure. All components work together according to the standards of harsh hydraulic engineering conditions to form an integrated anti-freezing device that is retractable, splicable, quick-replaceable, corrosion-resistant, and has a long service life. It completely solves the industry problems of difficult maintenance, poor adaptability, low safety, and cumbersome construction of traditional gate anti-freezing solutions.

[0017] The basic load-bearing structure of the module is the embedded part box 6, which is integrally formed using special anti-corrosion and sealing materials such as stainless steel and anti-corrosion alloy. It has the core characteristics of high strength, impact resistance, corrosion resistance and excellent sealing performance. It can be buried in concrete for a long time and perfectly adapts to the harsh working conditions of underwater, high humidity, low temperature and silt erosion. It fully meets the stringent requirements of long-term buried use in water conservancy projects. The internal cavity of the embedded part box 6 and the inner movable box 2 adopt a precision sliding fit structure. The inner movable box 2 can be freely pulled and pushed along the axial direction of the cavity of the embedded part box 6. During maintenance and replacement, the internal heating components can be quickly taken out without removing the embedded parts. This fundamentally solves the industry pain points of traditional antifreeze devices that are fixed and welded, cannot be disassembled and require destructive construction for maintenance.

[0018] Considering that traditional antifreeze devices are integral rigid structures, they cannot be flexibly adjusted according to the actual length and heating range of the gate embedded parts. Moreover, on-site splicing requires complex processes such as welding and drilling, resulting in long construction cycles and high labor costs. Therefore, a slot 9 is integrally formed on one side of the inner movable box 2, and a block 7 is fixedly connected on the other side. The block 7 and the slot 9 adopt a high-precision clearance fit design, which allows for smooth insertion without jamming and tight connection without loosening. This enables rapid positioning and seamless splicing between adjacent inner movable boxes 2, meeting the core technical requirements of modular quick-connect connection in the disclosure document.

[0019] During operation, on-site construction personnel only need to align the locking block 7 of one inner movable box 2 with the locking slot 9 of the adjacent inner movable box 2 and push it in smoothly to complete the mechanical connection between modules. There is no need for complex processes such as welding, bonding, and drilling, and a single person can complete the operation. Its technical advantages are that the connection between adjacent boxes is firm and reliable, and the disassembly and assembly are convenient and efficient. It can be freely spliced ​​and extended according to the length of the embedded parts and the size of the heating area, flexibly adapting to the antifreeze requirements of long-distance and large-area gate embedded parts. At the same time, the modular and segmented design facilitates mass production in the factory and segmented transportation on site, which greatly reduces the engineering production and transportation costs.

[0020] Considering the problems of traditional antifreeze devices where heating cables are directly exposed on the surface of metal embedded parts, and the cables are fixed to the structure as a whole, making overall replacement impossible and requiring the removal of the entire embedded part and antifreeze system for partial damage, a dedicated heating mechanism is installed inside the inner movable housing 2. This heating mechanism is the core component for the module to achieve its ice-melting and antifreeze function, mainly consisting of a support housing 3 and a heating cable 1. The support housing 3 is slidably assembled within the internal cavity of the inner movable housing 2, forming a three-layer protective structure with the embedded part housing 6 and the inner movable housing 2. The heating cable 1 is movably arranged inside the support housing 3, completely encapsulated and isolated, avoiding direct contact with metal embedded parts, water, and sediment. This structurally eliminates safety risks such as mechanical damage, leakage, and short circuits, significantly improving the system's operational safety.

[0021] During operation, the heating cable 1 continuously and stably generates heat after being connected to an external power source. The heat is evenly conducted to the surface of the gate embedded parts through the bearing housing 3, continuously breaking up ice formation and melting the existing ice layer to achieve long-term anti-freezing. The bearing housing 3 provides secondary protection for the inner movable housing 2 and can be pulled out as a whole along with the inner movable housing 2. Its technical effect is that the heating components can be inspected and replaced independently and quickly. Local damage does not require the entire system to be dismantled, which greatly reduces the difficulty of maintenance and the cost of operation and maintenance throughout the entire life cycle, while improving the stability and durability of the system operation.

[0022] Considering that the heating cable 1 is prone to displacement, entanglement, and stacking in the box due to transportation bumps, installation shaking, and operation vibration, resulting in local overheating and burnout or uneven temperature distribution, and thus incomplete de-icing and icing blind spots, the heating mechanism is also equipped with multiple fixing buckles 8. The multiple fixing buckles 8 are evenly fixed and installed on the inner wall of the carrying box 3 at equal intervals along the length direction of the carrying box 3. The fixing buckles 8 adopt an elastic clamping structure, and the clamping end is tightly abutted against the heating cable 1 to achieve rigid positioning constraint on the heating cable 1 and ensure that the cable layout is always fixed.

[0023] During operation, the fixing buckle 8 continuously clamps and constrains the heating cable 1, effectively preventing the cable from shifting, deviating, or tangling during transportation, installation, and long-term operation, ensuring that the cable layout always meets the design requirements. Its technical effect is that the heating cable 1 is precisely fixed in position, the heat output is uniform and stable, there are no blind spots of local high temperature or low temperature, ensuring a balanced temperature field distribution in the antifreeze area, significantly improving the ice melting efficiency and the overall service life of the equipment.

[0024] Considering that traditional heating cables are laid in a straight line, which has technical defects such as discontinuous temperature field coverage, scattered heat distribution, incomplete ice melting, and many ice-forming blind spots, the heating cable 1 is laid in a U-shape inside the bearing box 3. The U-shape laying is the key design of this module to optimize the temperature field distribution and improve the ice melting effect, which fully meets the core technical requirement of "forming a continuous and stable temperature field" in the patent disclosure.

[0025] During operation, the U-shaped structure ensures that the heating area of ​​the heating cable 1 fully and continuously covers the entire inner cavity of the supporting box 3, and the heat is evenly diffused to all the anti-freezing parts of the gate embedded parts without any dead corners. Its technical effect is to form a continuous, stable and uniform temperature field, completely eliminate the icing blind spots of the gate embedded parts, and significantly improve the ice melting effect. At the same time, the U-shaped laying can maximize the heating length within the limited box space, improve the thermal energy utilization rate and reduce the energy consumption of the equipment.

[0026] Considering that the top of the embedded part box 6 is directly exposed and prone to water, sand, and dirt accumulation, which can lead to corrosion of internal electrical components, short circuits in connectors, overheating and failure, and significantly shorten the service life of the device, a cover 4 is movably connected to the upper surface of the embedded part box 6. The cover 4 and the embedded part box 6 are made of the same anti-corrosion and sealing material, and have the same corrosion resistance and sealing performance. Both of them have standardized screw holes 5 with corresponding positions on their surfaces. The screw holes 5 are designed with national standard size, which can be used to pass through and lock standard fasteners such as bolts and screws, making installation convenient and highly versatile.

[0027] During operation, the cover 4 is smoothly placed on top of the embedded part box 6, and the fasteners are passed through the corresponding screw holes 5 to complete the fixed installation. The cover 4 completely covers the box opening, forming a fully enclosed protective space. Its technical effect is to effectively prevent water, mud, impurities, and frost from entering the box, achieving multiple protections such as waterproofing, dustproofing, corrosion prevention, and impact resistance, extending the overall service life of the module. At the same time, the cover is easy to install and remove, and does not affect the pull-out inspection and replacement of internal components.

[0028] In summary, the core improvement of this embodiment compared to existing traditional antifreeze technology lies in the following: Through the precise sliding fit structure between the inner movable housing 2 and the embedded part housing 6, the inner movable housing 2 has a free pull-out function, allowing the heating cable 1 and the supporting housing 3 to be removed as a whole. This enables quick replacement of single-section modules without removing the embedded parts or gates in case of partial damage, effectively solving the shortcomings of traditional antifreeze devices that are not replaceable, cumbersome to maintain, and costly. This significantly improves the convenience of disassembly and maintenance, and greatly reduces equipment operation and maintenance costs. Simultaneously, the inner movable housing 2 achieves rapid positioning and splicing of adjacent modules through the locking blocks 7 and slots 9. Combined with the standardized fastener fixing structure of the cover 4 and screw holes 5, no complex tools or professional procedures are required, greatly simplifying the on-site installation process. This allows for rapid completion of long-distance, large-area heating area laying operations, significantly improving construction efficiency compared to traditional solutions. In addition, the module adopts a non-standard customized design, which can be flexibly adapted to different embedded parts such as arc gates and plane gates. Its sealing and corrosion resistance fully meet the long-term use requirements of hydraulic engineering environment. The segmented independent circuit design of heating cable further improves the system safety and maintainability, fully meeting the use requirements of safe, efficient, durable and easy-to-maintain antifreeze device for water conservancy projects.

[0029] To achieve rapid, standardized, and compliant installation of the aforementioned quick-connect heating cable anti-freezing module, this embodiment also provides a matching installation method, the specific steps of which are as follows: S1: Based on the actual shape, size, and installation position of different embedded parts such as arc gates and plane gates at the construction site, non-standard customized processing is carried out to produce suitable pull-out movable inner box 2, embedded part box 6 and load-bearing box 3. The dimensional accuracy and fitting tolerance of each component are strictly controlled to ensure perfect fit with the embedded part cavity. S2: The finished inner movable box 2 is precisely slidably assembled into the internal cavity of the embedded part box 6. The smoothness of the pull-out is repeatedly adjusted to ensure that there is no jamming, no offset, and no looseness, so as to meet the design and usage requirements. S3: Based on the actual length of the antifreeze heating area of ​​the gate embedded parts, multiple inner movable boxes 2 are seamlessly spliced ​​by the gap fit between the card block 7 and the card slot 9 to ensure that the adjacent modules are firmly connected, tightly sealed, without gaps or misalignment; S4: After fixing the heating cable 1 with the fixing buckle 8, arrange it evenly inside the bearing box 3 in a U-shape. Check the cable laying pattern, fixing effect and insulation performance. After confirming that there are no errors, put the bearing box 3 into the inner movable box 2 as a whole. S5: Smoothly place the cover 4 on the top of the embedded part box 6, ensuring that the cover 4 and the screw holes 5 of the embedded part box 6 are precisely aligned. Insert the standard fasteners and tighten them evenly to complete the overall mechanical installation of the module. Connect the external power supply of the heating cable 1 and conduct a comprehensive power-on test, focusing on checking the uniformity of the temperature field distribution, heating effect, joint insulation performance, and sealing and waterproof performance. Once all indicators meet the standards, the module can be put into use. For subsequent maintenance, the heating component can be quickly removed for inspection and replacement by simply pulling out the inner movable box 2, without removing the embedded part.
