TECHNICAL FIELD
[0001] The present application relates to the field of shipbuilding technology, and particularly relates to a rainproof structure of a cabin-penetrating piece on an outdoor deck. BACKGROUND
[0002] When arranging air conditioners or electrical equipment on the deck surface of a ship, pipelines or cables need to penetrate the deck to enter the cabin, which involves strict water-tightness requirements. In the related art, a gooseneck (inverted U-shaped or elbow-shaped) cabin-penetrating sleeve is usually installed at the deck opening, the inner diameter of the sleeve is larger than the copper pipe or cable that penetrates through, and sealing filler is injected into the sleeve, which plays a sealing role after the filler is solidified.
[0003] However, this design has significant defects. In order to ensure the bending radius of the copper pipe or cable, the size of the gooseneck sleeve is usually large, which occupies the deck space. More importantly, since the sealing filler is filled in the curved gooseneck pipe, when the pipeline or cable needs to be maintained, repaired or replaced later, the solidified filler is difficult to remove by mechanical means, which makes the pipeline unable to be pulled out. In actual operation, the gooseneck sleeve can only be destructively cut and removed to achieve the purpose of repair, which greatly increases the difficulty and economic cost of the later maintenance of the ship.
[0004] Therefore, it is necessary to improve the existing rainproof structure technology of the cabin-penetrating piece on the outdoor deck to overcome the defects of the prior art. SUMMARY
[0005] In order to overcome the problems in the related art, the purpose of the present application is to provide a rainproof structure of a cabin-penetrating piece on an outdoor deck, which overcomes the problems of poor maintenance convenience and high maintenance cost of the cabin-penetrating piece in the prior art by setting the cabin-penetrating body in a straight-through form and cooperating with an independent detachable box-type rainproof cover.
[0006] A rainproof structure of a cabin-penetrating piece on an outdoor deck comprises: a straight-through cabin-penetrating sleeve extending upward in a direction away from the deck surface, the straight-through cabin-penetrating sleeve having an axial inner cavity, and the axial inner cavity being filled with solidified filler for sealing the pipeline; a box-type rainproof cover covering the top end of the straight-through cabin-penetrating sleeve; the bottom of the box-type rainproof cover is fixedly connected to the deck or the root of the straight-through cabin-penetrating sleeve in a detachable manner by fasteners, and the inner wall of the box-type rainproof cover is radially spaced apart from the outer wall of the straight-through cabin-penetrating sleeve to form a turning accommodation cavity in the box-type rainproof cover, the turning accommodation cavity being communicated with the axial inner cavity; The side wall of the box type rain cover is provided with a through groove for pipeline, the through groove penetrates the side wall along the radial direction of the straight-through penetrating cabin sleeve, and the position of the through groove in the height direction enables the pipeline to extend in an outwardly downward inclined posture.
[0007] Further, the bottom of the box type rain cover has a circumferentially extending mounting flange, and a plurality of mounting holes are formed in the mounting flange. The fastener includes a plurality of bolt assemblies, the bolt assemblies pass through the mounting holes in the mounting flange, and are locked with the root of the deck or the straight-through penetrating cabin sleeve to press and fix the mounting flange. After the bolt assembly is removed, the box type rain cover is allowed to be removed axially along with the mounting flange to expose the straight-through penetrating cabin sleeve.
[0008] The mounting flange cooperates with the bolt assembly, and the axial removal operation mode is clear. By providing the mounting flange with holes at the bottom of the box and using bolt assemblies for locking, a standardized and reliable mechanical connection mode is provided. Compared with welding or complex buckle structure, the bolt connection has higher fastening force and vibration resistance (adapted to the vibration environment of the ship). After the bolt is removed, the box is allowed to be removed axially, and during maintenance, the operator can vertically pull up and remove the rain cover without being hindered by the lateral pipeline. This operation path is consistent with the extension direction of the straight-through sleeve, maximizing the convenience of disassembly and achieving rapid exposure of the internal structure.
[0009] Further, it also includes: The mounting base is welded and fixed to the deck and surrounds the outside of the root of the straight-through penetrating cabin sleeve, and the mounting base has a horizontal mounting surface higher than the surface of the deck. The mounting flange is supported on the horizontal mounting surface of the mounting base, and the bolt assembly is locked between the mounting flange and the mounting base.
[0010] The mounting base welded to the deck is added, and a horizontal mounting surface higher than the deck surface is provided. The deck of the ship often has flatness error or deck water. The installation base can provide an absolutely horizontal and elevated installation platform. The elevated installation surface avoids direct contact between the rain cover and the deck water, preventing the risk of corrosion and leakage at the joint. The bolt is fixed on the base instead of directly drilling and tapping on the deck, avoiding damaging the water-tight structure of the deck, and the base is fixed by welding, ensuring the absolute water-tightness of the root.
[0011] Further, the box type rain cover includes: A top plate covers the top end opening of the straight-through penetrating cabin sleeve. a side plate extending downward from an edge of the top plate to a root of the through-penetrating passage sleeve or the deck, the side plate enclosing the turning accommodation cavity; wherein the through-slot is formed on the side plate.
[0012] The enclosing structure of the top plate and the side plate is defined, and the through-slot is formed on the side plate. The top plate constitutes the first line of defense against vertical rainfall, completely blocking the path of rainwater falling directly into the pipe opening; the side plate encloses a relatively closed internal chamber, effectively resisting the common horizontal wind and rain at sea. The through-slot is formed on the side plate rather than the top plate, which geometrically eliminates the possibility of rainwater entering the cover through the opening by gravity, and builds a three-dimensional rainproof barrier.
[0013] Further, the through-slot is configured as a notch extending upward from a bottom edge of the side plate, the notch having a width greater than the outer diameter of the penetrating pipeline; The notch allows the box-type rain cover to be separated from the through-penetrating passage sleeve and the penetrating pipeline by relatively sliding the penetrating pipeline out of the notch without cutting off the penetrating pipeline.
[0014] The through-slot is configured as a notch (U-shaped slot) extending upward from the bottom edge. If the through-slot is a closed round hole, the penetrating pipeline must be cut off before disassembling the rain cover. The design uses a notch structure with an open bottom, and the pipeline can be relatively slid out of the notch when disassembling the rain cover. When maintaining or replacing the rain cover, or checking the internal filler condition, there is no need to cut off or remove the running cable and refrigerant pipe, achieving truly non-destructive disassembly, greatly improving maintenance efficiency and reducing equipment downtime.
[0015] Further, the inner wall of the box-type rain cover and the top end opening of the through-penetrating passage sleeve have a minimum vertical distance, and the inner wall of the box-type rain cover and the outer wall of the through-penetrating passage sleeve have a minimum radial distance; The minimum vertical distance and the minimum radial distance are both greater than the minimum bending radius allowed by the penetrating pipeline, so that the pipeline has sufficient bending space when turning from vertical upward to horizontal or downward inclined in the turning accommodation cavity.
[0016] The interval distance (vertical and radial) is quantified to be greater than the minimum allowable bending radius of the pipeline. Both air conditioning copper pipes and power cables have certain hardness. If forced to bend at a small radius, the copper pipe will be flattened or the cable insulation layer will be broken. From the perspective of engineering, the turning accommodation cavity has sufficient physical space, so that the pipeline can maintain a smooth natural bending arc during the transition from vertical to lateral. This not only protects the physical properties of the pipeline itself and prevents damage caused by stress concentration, but also ensures that the pipeline is not squeezed against the inner wall of the rain cover due to space constraints, ensuring long-term stability of the installation.
[0017] Further, the through slot has a top edge limiting the height of the pipeline, and the top edge is lower than the top end opening of the straight-through cabin sleeve in the height direction; The height difference between the top edge and the top end opening of the straight-through cabin sleeve forces the pipeline to pass out from the axial inner cavity to pass through the through slot, to pass over the top end opening of the straight-through cabin sleeve and then bend downward to pass out from below the top edge, thereby using the bending form of the pipeline itself to block rainwater from flowing along the outer wall of the pipeline into the axial inner cavity.
[0018] The height difference between the top edge of the through slot and the top end opening of the sleeve is defined. This structure forces the use of gravity to build a raindrop prevention bend. Because the outlet (through slot) is lower than the inlet (sleeve opening), the pipeline must first climb over the sleeve opening and then descend to pass out in the cavity. This inverted U-shaped pipeline trend physically cuts off the possibility of external rainwater climbing along the pipeline surface and entering the sleeve. Even in heavy rain, rainwater attached to the outside of the pipeline will flow to the outside of the through slot due to gravity and drip onto the deck, rather than against gravity to enter the interior, thereby achieving excellent rainproof performance.
[0019] Further, an annular gap is formed between the inner wall of the straight-through cabin sleeve and the pipeline passing through it; The solidified filler fills the annular gap and solidifies to form a sealing plug, which is completely located inside the straight-through cabin sleeve, and the top surface of the sealing plug is covered by the box-type rain cover.
[0020] The sealing plug is completely located inside the sleeve and the top surface is covered by the rain cover. A "double protection" mechanism is established. The sealing filler itself is not directly exposed to the natural environment, and the rain cover blocks direct sunlight (prevents ultraviolet aging) and sea wave impact (prevents mechanical damage), significantly extending the service life of the sealing filler. The sealing plug formed by the solidification of the filler in the annular gap is the last line of defense against water, and by placing it inside the straight pipe, the binding force of the pipe wall ensures the tightness of the sealing structure.
[0021] Further, the straight-through cabin penetrating sleeve is a round pipe or a square pipe made of metal, and the bottom end of the straight-through cabin penetrating sleeve is welded to the cabin penetrating opening of the deck along the full circumference.
[0022] Metal material and full-circumference welding. The structural strength and watertightness of the root of the cabin penetrating part are ensured. The metal material provides sufficient strength to resist deck wave impact and mechanical collision; the full-circumference welding eliminates the gap between the sleeve and the deck, preventing water from leaking into the cabin from the root of the sleeve, and meeting the strict requirements of ship classification specifications for deck watertightness.
[0023] Further, the rainproof structure of the outdoor deck cabin penetrating part is applied to a ship air conditioning pipeline system or an electrical system, wherein: The pipeline is a red copper pipe of a ship air conditioning system or a cable of an electrical equipment, and the pipeline is arranged in a form of extending upward out of the straight-through cabin penetrating sleeve and then bending downward to pass through the through slot; The height of the straight-through cabin penetrating sleeve is such that the top end opening is higher than the preset water accumulation safety liquid level of the deck of the ship.
[0024] This is an adaptive design for the special environment of the ship. The deck may have water accumulation phenomenon of "upward wave" in rough sea conditions. By limiting the height of the straight pipe to be higher than the preset water accumulation safety liquid level, the water accumulation on the deck surface is prevented from flowing back into the pipe opening in terms of physical height. At the same time, for specific pipelines such as red copper pipes, this structure avoids the need for complex pre-bending of the copper pipe during installation to adapt to the operation of the goose neck pipe, reducing the construction difficulty and the risk of work hardening and fracture of the copper pipe.
[0025] The beneficial effects of the present application are: The rainproof structure of the outdoor deck cabin penetrating part provided by the present application changes the bending filling form of the traditional goose neck pipe by arranging the straight-through cabin penetrating sleeve extending upward in the direction away from the deck surface and filling the solidified filler for sealing the pipeline in the axial inner cavity of the straight-through cabin penetrating sleeve, so that when the pipeline needs to be repaired or replaced, the solidified filler in the straight-through cabin penetrating sleeve can be directly cleaned by removing the upper shelter, greatly reducing the difficulty of pipeline pulling out and filler removal; at the same time, the box type rain cover arranged at the end of the straight-through cabin penetrating sleeve is fixedly connected through fasteners, which can not only shield rainwater through the box type rain cover during normal use, but also completely expose the port of the straight-through cabin penetrating sleeve by disassembling the box type rain cover during maintenance, so that convenient maintenance is realized without damaging the main structure of the cabin penetrating part.
[0026] The radial spacing is kept between the inner wall of the box type rain cover and the outer wall of the straight-through penetration sleeve to form a turning accommodating cavity, and the through groove is opened on the side wall, so that the pipeline can be bent by using the space of the turning accommodating cavity after penetrating out of the straight-through penetration sleeve, and the pipeline is in an outwardly downward inclined posture and penetrates out of the through groove. This structure forces the pipeline to form a gravity flow pattern, effectively prevents rainwater from flowing back along the outer wall of the pipeline into the axial inner cavity of the straight-through penetration sleeve, and ensures excellent rainproof performance while using a straight pipe structure that is convenient to maintain.

DETAILED DESCRIPTION
[0029] The preferred embodiments of the present application will be described in more detail by referring to the attached drawings. Although the preferred embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.
[0030] Embodiment 1 As shown in Figs. 1-3 , the present embodiment provides an outdoor deck 200 penetration piece rainproof structure, which comprises: a straight-through penetration sleeve 110 extending upward in a direction away from the surface of the deck 200, the straight-through penetration sleeve 110 having an axial inner cavity 111, the axial inner cavity 111 being filled with a solidified filler 112 for sealing a pipeline 300; a box type rain cover 120 covering the top end of the straight-through penetration sleeve 110; The bottom of the box-shaped rain cover 120 is detachably fixed to the deck 200 or the root of the straight-through penetration sleeve 110 by fasteners, and the inner wall of the box-shaped rain cover 120 is radially spaced from the outer wall of the straight-through penetration sleeve 110 to form a turning accommodation cavity 123 in the box-shaped rain cover 120, which is in communication with the axial inner cavity 111; A through groove 121 is formed in the side wall of the box-shaped rain cover 120 for the pipeline 300 to pass through, and the through groove 121 penetrates the side wall along the radial direction of the straight-through penetration sleeve 110, and the position of the through groove 121 in the height direction is such that the pipeline 300 can extend in an outwardly downward inclined posture.
[0031] The straight-through penetration sleeve 110 is a basic component of the penetration structure. In a specific implementation, the straight-through penetration sleeve 110 is designed as a tubular member extending in a direction away from the surface of the deck 200 (i.e., vertically upward). The material thereof is usually selected from metal materials with high strength and corrosion resistance, such as marine steel or stainless steel, to resist the harsh working conditions of the deck 200 environment. Unlike the traditional inverted U-shaped goose neck pipe, the sleeve body of the present embodiment remains straight and does not contain any complex curved section.
[0032] The bottom end of the sleeve is fixed at the opening of the deck 200 by permanent connection means such as welding, to ensure the water tightness of the root. An axial inner cavity 111 is formed in the sleeve, which is a passage for the pipeline 300 (such as a seed pipe or a cable) to pass through the deck 200.
[0033] In order to realize the sealing of the penetration, after the pipeline 300 passes through, the axial inner cavity 111 will be filled with solidified filler 112. Such filler can be a fireproof and waterproof sealing putty approved by the classification society, which is filled in the annular gap between the pipeline 300 and the inner wall of the sleeve, and forms a solid sealing plug after solidification, preventing seawater or rainwater from penetrating into the cabin through the inside of the sleeve.
[0034] The core reason for being designed in a straight-through form is the convenience of maintenance: when the pipeline 300 needs to be replaced, since the sleeve is straight, the maintenance personnel can directly clean the solidified filler vertically downward from above by using mechanical tools (such as a drill bit and a spatula), without any obstruction of a bend, so that the originally extremely difficult digging work becomes simple and efficient, and the pipeline 300 is also easily pulled out.
[0035] The box-shaped rain cover 120 is an independent rainproof component covering the straight-through penetration sleeve 110. The rain cover is in a box-shaped structure, which can be designed in various forms such as a cube, a cuboid or a cylinder, and the top thereof is closed and hollow inside.
[0036] The box-type rain cover 120 is arranged at the end (i.e. the top end) of the extension direction of the straight-through cabin penetrating sleeve 110, and functions to physically shield the rain from above.
[0037] The box-type rain cover 120 is not installed in close contact with the sleeve, but rather a significant radial gap is maintained between the inner wall of the rain cover and the outer wall of the straight-through cabin penetrating sleeve 110. This radial gap creates a ring-shaped or square-shaped space around the top of the sleeve inside the rain cover, i.e. a "turning accommodating cavity 123". The existence of this cavity provides sufficient space for the pipeline 300 to bend and turn vertically out of the straight pipe, smoothly transitioning from a vertical posture to a horizontal or inclined posture, thereby avoiding damage to the pipeline 300 due to forced bending.
[0038] In terms of connection, the bottom of the box-type rain cover 120 is fixedly connected in a detachable manner. The fixing point can be selected on the deck 200 or at the root position of the straight-through cabin penetrating sleeve 110. The specific connection means can adopt a bolt assembly 130, a buckle with locking function, or a pin shaft connection, etc. The purpose of this detachable design is that, in daily use, the rain cover is integrated with the deck 200 or the sleeve to provide stable protection; when the pipeline 300 needs to be repaired or the filler needs to be cleaned, the entire rain cover can be removed by loosening the fastener, completely exposing the internal straight-through cabin penetrating sleeve 110 and the filler area, thereby restoring the above-mentioned straight pipe maintenance state.
[0039] A through slot 121 is formed in the side wall of the box-type rain cover 120. The through slot 121 is the outlet through which the pipeline 300 finally leads to the external equipment. The direction of the through slot 121 is along the radial direction relative to the straight-through cabin penetrating sleeve 110, meaning that the pipeline 300 spreads outwards rather than upwards.
[0040] The position of the through slot 121 in the height direction is specifically designed to match the flexibility or pre-bending shape of the pipeline 300, so that the pipeline 300 can extend in an outwardly inclined posture when passing through the through slot 121.
[0041] Specifically, the pipeline 300 is vertically upwardly led out of the straight pipe, bends after entering the turning accommodating cavity 123, spans the straight pipe opening, and then tilts downwardly through the through slot 121 in the side wall. This arrangement utilizes the principle of gravity, so that the rainwater attached to the external pipeline 300 can only flow to the outside of the lower through slot 121 and drip onto the deck 200 under the action of gravity, and cannot flow upwardly over the straight pipe opening and into the sleeve interior. Even in rainy weather, it is difficult for rainwater to flow back into the cabin against the force of gravity and the structural height difference.
[0042] In addition to the above-mentioned embodiments, the present embodiment can also be implemented in the following ways: Regarding the shape and material of the through-penetration sleeve 110, although the embodiment mainly describes a cylindrical metal pipe, in actual application, the cross-sectional shape of the through-penetration sleeve 110 can also be designed as a rectangle, a square, an ellipse, or a racetrack shape to adapt to the needs of arranging flat cables or multiple pipelines 300 side by side; in addition to the conventional carbon steel or stainless steel, in specific areas where the fire rating is allowed, high-strength marine aluminum alloy, copper alloy, or even composite materials such as glass steel can also be used. In addition, the inner cavity of the through-penetration sleeve 110 can be a single-cavity structure, or can be divided into multiple independent sub-chambers by setting internal partitions, so as to physically isolate power cables and signal cables, or pipelines and lines, and reduce electromagnetic interference or heat transfer.
[0043] Regarding the structure and shape of the box-type rain cover 120, the box concept is not limited to a cubic shape, and the overall appearance of the box-type rain cover 120 can be a cylinder (cylindrical), a hemisphere, a prism (such as a hexagonal prism or an octagonal prism), or a special-shaped body with a sloping roof structure, as long as it can cover the through-penetration sleeve 110 and form an internal turning accommodation cavity 123. The top plate of the box-type rain cover 120 can be designed as a plane, or as a conical surface or a circular arc surface with a high middle and a low periphery, to facilitate the rapid diversion of external rainwater and prevent water accumulation on the top. The material of the box-type rain cover 120 is also diverse, in addition to metal plate welding or stamping forming, it can also be made of anti-UV aging engineering plastics (such as ABS, polycarbonate), glass fiber reinforced plastic, etc. through injection molding or molding process to reduce weight and improve corrosion resistance.
[0044] Regarding the specific implementation form of the detachable connection, in addition to the bolt assembly 130 cooperating with the installation flange 122 mentioned in the embodiment, other mechanical connection means can also be used. For example, a stand with an external thread can be provided on the deck 200 or the base, and the rain cover can be holed at the corresponding position and locked by a wing nut to facilitate hand-free quick disassembly; or a quick clamp, a snap lock, or a hinge cooperating with a latch structure can be used to realize tool-free disassembly of the rain cover. The basic interface of the connection can also be changed, for example, the deck 200 is not provided with a protruding installation base 210, but a flange plate with screw holes is welded directly on the deck 200 plane; or the rain cover is not connected with the deck 200, but is clamped and fixed directly on the outer wall of the root of the through-penetration sleeve 110 exposed on the deck 200 (through a hoop structure).
[0045] Regarding the through slot 121, in order to protect the pipeline 300, a rubber ring, a nylon bushing or a rolled edge structure can be installed at the edge of the through slot 121 to prevent the metal sharp edge from cutting the pipeline 300 skin. The form of the through slot 121 can also be a closed long hole located in the middle of the side wall, at which time the rain cover can be made of two halves to facilitate installation. In addition, in order to further enhance the rainproof effect, a rain eave (eyebrow) can be added above and outside the through slot 121, or a soft rubber curtain or bristle sealing strip can be provided at the through slot 121 to close the remaining gap as much as possible while allowing the pipeline 300 to pass through, preventing splashing water mist from entering.
[0046] The rainproof structure can not only be one pipe and one cover, but also multiple pipes and one cover. That is, inside a larger box type rain cover 120, the cover is provided with two or more straight-through penetration sleeves 110 arranged side by side, all the pipelines 300 share one large internal turning chamber, and are led out from different through slots 121 of the side wall or from the same widened through slot 121. This intensive design is suitable for areas where pipelines 300 are dense, such as the deck 200 area above the control room.
[0047] Embodiment 2 As shown in Figs. 1-3 , the present embodiment provides an outdoor deck 200 penetration piece rainproof structure. The present embodiment is further elaborated on the basis of embodiment 1, and further refines the fixed connection form between the box type rain cover 120 and the deck 200 and its support structure, and particularly focuses on improving the stability of the rainproof structure in a high vibration environment of the ship and the corrosion resistance of the rainproof structure in a water accumulation environment of the deck 200.
[0048] The specific structure of the present embodiment includes the straight-through penetration sleeve 110 and the box type rain cover 120 as described in embodiment 1, and mainly introduces the mounting base 210 and the flange bolt connection assembly.
[0049] The mounting base 210 is a transitional component added to avoid direct drilling and tapping on the deck 200 steel plate. In specific implementation, the mounting base 210 is designed as a rectangular or circular metal fence structure (also known as a fence or flange seat), which is arranged outside the root of the straight-through penetration sleeve 110 and does not contact the sleeve, but is independently welded and fixed to the surface of the deck 200. The mounting base 210 has a certain height (for example, 50mm to 100mm), and the top end face is processed to form a flat horizontal mounting surface.
[0050] The core purpose of setting the mounting base 210 is to lift, which lifts the connection joint of the rain cover to a safe height from the deck 200 plane, thereby avoiding the long-term immersion of the connection in the water or oil accumulated on the deck 200, significantly reducing the risk of fastener corrosion and seal failure.
[0051] In this embodiment, the bottom edge of the rain cover is not simply a straight edge, but is processed by a bending process to form a mounting flange 122 extending circumferentially outward (or inward). The mounting flange 122 is pre-drilled with a plurality of evenly distributed mounting holes, which are accurately aligned with the corresponding hole positions on the mounting base 210. The presence of the mounting flange 122 increases the structural rigidity of the bottom of the rain cover and provides a wide enough contact surface to facilitate the application of compression force.
[0052] This embodiment uses a bolt assembly 130 for connection. During assembly, the mounting flange 122 of the box-shaped rain cover 120 is attached to the horizontal mounting surface of the mounting base 210 (rubber sealing gaskets can be added between the two to further prevent water), the bolt shaft passes through the mounting hole, and is locked with a flat washer, spring washer and nut. The use of spring washers or self-locking nuts is to cope with the continuous low-frequency vibration caused by the main engine and waves during ship navigation, to prevent the connection from loosening.
[0053] When maintenance is needed for the internal straight-through passage sleeve 110, the operator only needs to remove the above-mentioned bolt assembly 130 using a standard wrench, at which time the box-shaped rain cover 120 is unlocked from the mounting base 210. Since the mounting flange 122 is designed integrally with the rain cover, and the straight-through passage sleeve 110 is located in the center of the cover body, the operator can directly hold the rain cover and remove it together with the mounting flange 122 in the axial direction (vertically upward). This process is completely unaffected by the straight-through passage sleeve 110, and after removal, the straight-through passage sleeve 110 and the solidified filler 112 inside it are completely exposed in the center of the area surrounded by the mounting base 210, providing ample space for cleaning and making it easy to perform the cleaning operation.
[0054] This embodiment, through the combination of "welding base, flange flange, bolt locking", not only realizes the functions of rain protection and maintenance convenience, but also further solves the problem of easy failure of the connection in the high-salt, high-humidity, and high-vibration environment at sea, protecting the integrity of the deck 200 body (without the need to punch holes in the main deck 200).
[0055] In addition to the above-mentioned embodiments, the present embodiment can also be implemented in the following ways: Regarding the structural form of the mounting base 210, it can be replaced by an angle steel frame, that is, four angle steels are welded on the deck 200 to form a rectangular frame, and the upper flange of the angle steel is used as the mounting surface. This method is convenient and low in cost. In the area where the flatness of the deck 200 is good and there is no water accumulation, the mounting base 210 can be simplified to a group of studs directly welded on the deck 200, that is, the continuous coaming is cancelled, and only the stainless steel studs with external threads are welded at the positions corresponding to the mounting holes. The rain cover is directly sleeved on the stud and pressed by the nut. For high-speed passenger ships or aluminum superstructures that are sensitive to weight, the mounting base 210 can be an aluminum alloy flange seat or a composite material base connected by structural adhesive, so as to avoid electrochemical corrosion caused by contact between dissimilar metals.
[0056] Regarding the connection structure of the bottom of the rain cover, the direction of the mounting flange 122 can be adjusted from outward extension to inward extension. This inward flange design can hide the bolt assembly 130 inside the rain cover, making the appearance more neat and streamlined, and reducing the risk of tripping on the deck 200 (at this time, a hand hole needs to be opened in the side wall or operated through the bottom opening). In addition, the bottom of the rain cover does not necessarily need to be formed by bending a flange, but a solid flat iron or square steel can also be welded to thicken the bottom edge, and threaded holes are drilled and tapped thereon. In this way, nuts can be saved, and bolts can be directly locked from top to bottom, reducing the number of parts.
[0057] Regarding the fastener and locking method, in order to further improve the quick release experience, the standard hexagonal bolt assembly 130 can be replaced by a hinge bolt, that is, the bolt is hinged on the mounting base 210, an open slot (instead of a closed hole) is opened on the rain cover flange, and when disassembled, only the nut needs to be loosened and the bolt needs to be turned down. There is no need to completely remove the nut to prevent the loss of parts. Star-shaped handle knobs or butterfly nuts can also be used instead of ordinary nuts to achieve tool-free disassembly. In high-maintenance environments, even industrial-grade snap locks or eccentric clamping handles can be used to instantly press or release the rain cover through the lever principle.
[0058] Regarding the optimization of the waterproof connection interface, in addition to the flat pressing fit, a sleeve connection structure can also be used. That is, the outer diameter of the mounting base 210 is slightly smaller than the inner diameter of the rain cover, and the rain cover is like a lid that is sleeved outside the mounting base 210, forming a vertical overlapping area (skirt). At this time, the fastener can be connected from the side (horizontal direction) through the rain cover side wall and the mounting base 210 side wall. The advantage of this skirt cover design is that rainwater will directly flow through the joint and fall onto the deck 200, and there will be no water accumulation at the joint, so the waterproof reliability is higher than that of the flat seal.
[0059] As to the selection of sealing material, in addition to the conventional rubber gasket, dovetail groove or O-ring groove can be processed on the mounting surface of the mounting base 210, and a whole circle of silica gel sealing strip or EPDM foam strip is embedded therein. When the rain cover is pressed, the sealing strip is elastically deformed to fill the gap. This linear contact sealing requires less locking force than surface contact sealing, and is more suitable for the slight deformation of the deck 200.
[0060] Embodiment 3 As Figs. 1-3 shown, the present embodiment provides an outdoor deck 200 rainproof structure, which is further described on the basis of the above-mentioned embodiments, especially for the quick-release structure of the pipeline 300 in the online non-destructive repair. The present embodiment aims to solve the technical problem of how to completely remove the rain cover without cutting off the pipeline 300 and stopping the equipment operation when the pipeline 300 (such as electrical equipment cable or copper pipe filled with refrigerant) is in use.
[0061] In the present embodiment, the specific structure of the box-type rain cover 120 is disassembled into two main parts, the top plate and the side plate. The top plate covers horizontally above the top end opening 113 of the straight-through penetration sleeve 110, and its area is larger than the cross-sectional area of the sleeve, serving as the first barrier to block vertical rain. The side plate extends downward from the edge of the top plate until it reaches the surface of the deck 200 or the root installation position of the straight-through penetration sleeve 110, and the side plates on the four sides are connected to each other to form the aforementioned diversion and accommodation cavity 123 around the straight-through penetration sleeve 110.
[0062] The present embodiment has a highly targeted design for the through slot 121 on the side wall, which is designed as a notch (usually in the shape of an inverted U or a door opening) extending upward from the bottom edge of the side plate. The width of the notch is designed to be slightly larger than the outer diameter of the pipeline 300 (or the bundle of pipelines 300) to be penetrated, and the height of the notch is determined according to the height requirement of the curved pipeline 300.
[0063] In the traditional closed hole design, the pipeline 300 passes through the closed circular hole, causing the rain cover to be strung in the middle of the pipeline 300. If the rain cover is to be removed, the pipeline 300 must be cut off. In the present embodiment, since the bottom of the through slot 121 is open, when maintenance is needed, the operator only needs to loosen the fasteners at the bottom of the rain cover, and then vertically pull up the box-type rain cover 120. In this process, the penetrated pipeline 300 moves downward relative to the rain cover and naturally slides out of the notch at the bottom of the side plate. This process allows the rain cover to be completely separated from the straight-through penetration sleeve 110 and the pipeline 300, while the pipeline 300 remains connected without the need for power-off or refrigerant recovery. Online maintenance is achieved, greatly reducing the auxiliary workload.
[0064] To compensate for the potential loss of sealing due to the bottom opening, the gap is usually used in conjunction with the mounting base 210 or the sealing assembly in the installed state. When the rain cover is fixed in place, the pipeline 300 passes through the gap, and the bottom edges of the side plates on both sides of the gap are pressed against the mounting surface. In order to prevent the pipeline 300 from being cut by the metal edge at the gap, a U-shaped rubber protection strip is wrapped around the edge of the gap.
[0065] In addition to the above-mentioned embodiments, the present embodiment can also be implemented in the following ways: Regarding the plugging and sealing form of the through slot 121, in order to solve the problem of potential decrease in anti-surge ability caused by the bottom opening, a split sealing module scheme can be used. That is, a sliding groove is pre-installed at the U-shaped gap, and when the rain cover is installed in place, a door-shaped or two-piece rubber sealing block with a semicircular hole (such as EPDM material) that matches the outer diameter of the pipeline 300 is inserted. The sealing block not only fills the gap below the gap, but also tightly holds the pipeline 300 through interference fit to prevent rainwater from splashing into the interior along the pipe wall. Another alternative is to use a flap structure, which sets guide rails on both sides of the gap in the side plate. After installation, a metal flap slides down from top to bottom or up from bottom to top to close, leaving only a gap at the pipeline 300. This hard sealing structure has stronger wind pressure resistance.
[0066] Regarding the overall disassembly of the box-type rain cover 120, in addition to the above-mentioned overall pull-up type, it can also be designed as a split type. That is, the rain cover is no longer a single body, but is composed of two L-shaped or C-shaped half shells. The two half shells are connected by flanges on the sides and bolts. When maintaining, instead of pulling up, you only need to remove the side bolts and move the two half shells horizontally to the left and right sides.
[0067] Regarding the path form of the gap, in addition to the standard vertical inverted U-shaped gap, it can also be designed as an L-shaped or Z-shaped labyrinth gap. That is, the path of the pipeline 300 is not straight, but needs to be pulled up first, and then rotated at a certain angle to make the pipeline 300 come out. This zigzag path design itself can play a good rain-blocking role, and even without additional sealing elements, it can prevent rainwater from directly splashing in.
[0068] Regarding the function design of auxiliary maintenance, in order to further improve the convenience of inspection, a visual window can be opened on the side plate or top plate of the rain cover. The window is sealed and fixed with weather-resistant transparent polycarbonate (PC) plate or tempered glass. In this way, daily inspection personnel do not need to disassemble any bolts, but only need to observe through the window to observe whether the filler at the root of the straight-through through-cabin sleeve 110 shows signs of cracking, falling off or leakage. Only when it is confirmed that maintenance is needed will disassembly be performed.
[0069] In view of the risk of offshore wind and wave operation, a falling and losing prevention chain can be added to the rain cover. One end of the stainless steel chain is connected to the inner wall of the rain cover, and the other end is connected to the pipe wall of the straight-through penetration sleeve 110 or the base of the deck 200. When the bolt is removed, even if the rain cover is accidentally dropped, it will not fall into the sea or damage the deck 200, and it also prevents the rain cover from being blown away during disassembly in strong winds. In addition, a lifting handle or lifting ring can be welded to the top outer surface of the rain cover to facilitate maintenance personnel to firmly grasp and apply force even when wearing thick gloves.
[0070] Embodiment 4 As Figs. 1-3 shown, the present embodiment provides an outdoor deck 200 penetration rainproof structure, which is further described on the basis of the above-mentioned embodiment, further strictly limits the spatial geometric relationship between the straight-through penetration sleeve 110 and the box-type rain cover 120, and optimizes the arrangement form of the sealing filler to adapt to the protection requirements in severe sea conditions such as heavy rain and sea wave beating.
[0071] In the present embodiment, the inner wall of the box-type rain cover 120 is not arbitrarily covered outside the straight-through penetration sleeve 110, but needs to meet specific distance requirements: a minimum vertical distance is set between the inner surface of the top plate of the box-type rain cover 120 and the top end opening 113 of the straight-through penetration sleeve 110, and a minimum radial distance is set between the inner surface of the side plate of the box-type rain cover 120 and the outer wall of the straight-through penetration sleeve 110. The two distance values are not fixed, but are determined according to the physical properties of the pipeline 300 to be penetrated (such as air conditioning copper pipe or power cable), that is, they must be greater than the minimum bending radius allowed by the pipeline 300.
[0072] The air conditioning copper pipe has the characteristics of easy work hardening and easy flattening, and the large wire diameter cable has strong rigidity. If the internal space of the rain cover is too narrow, the pipeline 300 will be forced to form a very small sharp bend when it is pulled out vertically from the straight pipe and tries to turn sideways, which will cause the copper pipe cross section to deform and affect the refrigerant flow, or the cable insulation layer to break due to stress concentration. The present embodiment provides sufficient vertical and radial buffer space to ensure that the pipeline 300 can complete the path conversion from vertical upward to horizontal or downward inclined with smooth and natural curvature in the turning accommodation cavity 123, which not only protects the pipeline 300, but also avoids affecting the stability of the connection due to the rebound force pressing the inner wall of the rain cover.
[0073] In this embodiment, a mandatory gravity diversion barrier is constructed by structural height difference. The through-slot 121 is opened on the side wall of the rain cover, and its position is calculated accurately: the top edge of the through-slot 121 limits the height of the pipeline 300, and is obviously lower than the top opening 113 of the straight-through penetration sleeve 110 in absolute height. This structure with low outside and high inside forces the pipeline 300 drawn from the axial inner cavity 111 to follow a reverse U-shaped trajectory of first climbing upward to pass the sleeve opening and then bending downward to pass through the through-slot 121.
[0074] The core advantage of this trajectory design is to block the waterway by gravity. In stormy weather, even if rainwater adheres to the surface of the external pipeline 300 and tries to flow inward along the pipe wall, when it reaches the position of the through-slot 121, the rainwater cannot overcome the gravity to climb over the top opening 113 of the straight-through penetration sleeve 110 because the pipeline 300 assumes an upward climbing posture in the cavity, and can only gather at the lowest point of the pipeline 300 bending and drip on the deck 200. Thus, the possibility of rainwater flowing backward into the sleeve is completely eliminated in physical principle.
[0075] In this embodiment, a double protection arrangement is adopted. The solidified filler 112 is filled in the annular gap between the inner wall of the straight-through penetration sleeve 110 and the pipeline 300, and forms an integral sealing plug after solidification. The sealing plug is located completely inside the deep penetration sleeve 110, and its top surface does not exceed the sleeve opening and is completely covered by the upper box-shaped rain cover 120. This arrangement makes the sealing plug become the second line of defense, and the box-shaped rain cover 120 as the first line of defense bears the vast majority of external attacks. The rain cover blocks direct sunlight, preventing the sealing cement from aging and cracking due to long-term ultraviolet radiation; at the same time, it also blocks the direct impact of sea waves, preventing mechanical damage to the sealing structure. This design of sealing inside the cover significantly prolongs the service life of the sealing material, ensuring the water-tight reliability of the penetration structure throughout its life cycle In addition to the above-mentioned embodiments, the present embodiment can also be implemented in the following ways: Regarding the space construction of the turning accommodation cavity 123 and the pipeline 300 guide, in order to further regulate the bending shape of the pipeline 300, a prefabricated circular arc guide rib or support bracket can be added to the inner wall of the box type rain cover 120, with a curvature radius matching the minimum allowable bending radius of the pipeline 300, thereby physically supporting and lifting the pipeline 300, preventing the pipeline 300 from sagging due to gravity and causing excessive bending angle; or the height of the rain cover can be designed to be adjustable (for example, using a telescopic sleeve structure or multiple installation holes), so as to adjust the vertical distance between the top plate and the sleeve opening on site according to the actual thickness and hardness of the pipeline 300, and obtain the best bending space. For the protection of the pipeline 300 entering and exiting the sleeve opening, the top opening 113 of the straight-through cabin sleeve 110 can not only be a straight cut, but also be processed into a flared shape (horn mouth) or a smooth plastic retaining ring is installed to reduce friction and wear of the pipeline 300 when climbing over the pipe opening.
[0076] Regarding the rainproof reverse flow structure of low outside and high inside, the form of the side wall through slot 121 can be further upgraded. For example, instead of directly slotting the side wall, a downward inclined wire nozzle or elbow short pipe is extended outward, and the pipeline 300 is led out through the short pipe. This extended physical channel can more effectively block the invasion of rainwater carried by crosswind. In order to cope with extreme typhoon weather, one or more labyrinth water baffles can be arranged inside the rain cover between the through slot 121 and the straight-through cabin sleeve 110, forcing the entering air to be diverted multiple times, thereby separating and intercepting the water mist carried in the air by centrifugal force, so that it cannot reach the sleeve opening. In addition, in order to prevent condensation water from accumulating inside the rain cover due to temperature difference, a small one-way drainage hole or air vent plug can be opened at the lowest point of the rain cover bottom (i.e. at the installation of the flange 122), to ensure that any accidental water entering can be drained in time, keeping the cavity dry.
[0077] Regarding the material and form of the sealing system, in addition to the curing putty mentioned in the embodiment, the sealing structure inside the straight-through cabin sleeve 110 can also use a modular sealing system, that is, a compression sealing element composed of multiple layers of peelable rubber core and metal frame, which is convenient for adjusting a single cable without affecting the overall sealing. In areas with higher fireproofing requirements, the sealing plug can be designed as a composite structure, with the lower layer filled with fireproof expansion material and the upper layer covered with waterproof sealant. If the top surface of the sealing plug needs to be further protected, a light and thin air-permeable dust cover can be additionally installed at the pipe opening of the straight-through cabin sleeve 110, which allows the pipeline 300 to pass through but is not sealed, mainly used to block dust and insects from entering the small gap on the surface of the sealing filler.
[0078] Regarding the structure optimization of the through-penetration passage sleeve 110 itself, in order to prevent rainwater from flowing along the outer wall of the sleeve and accumulating at the root, a circular water-blocking skirt can be welded on the outer wall of the sleeve exposed to the deck 200, which is located outside the covering range of the rain cover or at the edge, guiding the water droplets flowing along the wall to directly drop on the deck 200, preventing them from seeping into the connecting gap at the bottom of the rain cover.
