Description

Technical Field

[0001] This invention relates to the field of marine floor drain technology, and in particular to a floor drain structure and construction method suitable for marine integrated bathrooms. Background Technology

[0002] In the drainage design of marine prefabricated bathrooms, multi-level drainage systems are widely used in medium and large cruise ships and offshore platforms due to their high space utilization and flexible layout. However, multi-level drainage systems require floor drains to penetrate the deck to connect the upper and lower layers of pipes. This design places stringent requirements on the material properties, sealing effect, and installation compatibility of the floor drains. Currently, the industry commonly uses a solution of direct-discharge floor drains installed in conjunction with deck openings, but this solution has revealed many problems in practical applications. On the one hand, the sealing performance of direct-discharge floor drains is poor, making it difficult to effectively prevent odors from rising from the lower space, affecting the air quality and user experience of the marine prefabricated bathroom. Especially after prolonged use, the sealing components are prone to aging and deformation, leading to a further decrease in sealing effectiveness. On the other hand, due to the poor compatibility between the deck openings and the floor drains, when the ship is subjected to turbulence and vibration during navigation, loosening and gaps can easily occur between the floor drain and the deck, leading to leakage problems. This not only damages the equipment and facilities in the lower space but may also affect the structural safety of the ship. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention provides a floor drain structure and its construction method suitable for marine integrated bathrooms, solving the technical problem that existing floor drain structures are difficult to adapt to turbulent environments and are prone to sealing failure. By changing to a split floor drain structure, the sealing performance between the floor drain structure, the waterproof tray, and the deck can be effectively improved.

[0004] This invention provides a drain structure suitable for marine integrated bathrooms. The bottom of the marine integrated bathroom consists of a waterproof tray and a deck, with a set distance between the waterproof tray and the deck. The deck has a first through hole, and the waterproof tray has a second through hole. The drain structure includes a drain lock nut, a flange lock nut, and a drain body. The drain lock nut includes an outer edge, an inner edge, and a first pipe. The outer edge is connected to the top outer side of the first pipe, and the inner edge is connected to the top inner side of the first pipe. The first pipe is inserted into the second through hole. The outer edge is attached to the top surface of the waterproof tray. A drain cover is provided on the top of the outer edge. A water seal is provided inside the first pipe, and the water seal is attached to and connected to the inner edge. The flange lock nut includes a top edge and a second pipe. The top edge is connected to the top outer side of the second pipe. The second pipe is sleeved and connected to the outer side of the first pipe. The second pipe and the first pipe are fixedly connected. The top edge abuts against the bottom surface of the waterproof pan. A first sealing gasket is provided between the outer edge, the top edge and the first pipe. The drain body includes a waterproof edge and a drain pipe. The waterproof edge is connected to the top outer side of the drain pipe and to the bottom surface of the deck. The drain pipe is disposed in the first through hole and sleeved on the first pipe. A second sealing gasket is disposed between the drain pipe and the first pipe.

[0005] A further improvement of the drain structure of the present invention for marine integrated bathroom is that the waterproof tray is recessed downward at the position corresponding to the second through hole to form a first step, the outer edge is connected to the first step, the top surface of the drain cover is flush with the top surface of the waterproof tray, and the top edge is fixedly connected to the bottom surface of the first step.

[0006] A further improvement of the drain structure of the present invention for marine integrated bathrooms is that the first sealing gasket is U-shaped.

[0007] A further improvement of the drain structure of the present invention applicable to marine integrated bathrooms is that the inner edge includes an inclined flow guiding surface and a horizontal mounting surface, and the water seal is mounted on the mounting surface.

[0008] A further improvement of the drain structure of the present invention for marine integrated bathrooms is that the outer wall of the first pipe is provided with an external thread, and the inner wall of the second pipe is provided with an internal thread. The internal thread is screwed into the external thread to fix the first pipe and the second pipe.

[0009] A further improvement of the drain structure of the present invention applicable to marine integrated bathrooms is that the diameter of the first through hole is larger than the diameter of the second through hole.

[0010] A further improvement of the drain structure of the present invention for marine integrated bathrooms is that the drain pipe is L-shaped.

[0011] A further improvement of the drain structure of the present invention for a marine integrated bathroom is that the top surface of the waterproof edge and the bottom surface of the deck are connected by welding.

[0012] The present invention also provides a method for constructing a floor drain structure suitable for marine prefabricated bathrooms. The method, performed using the floor drain structure described above, includes the following steps: The first through-hole was opened on the deck; The first sealing gasket is connected to the waterproof pan at the position corresponding to the second through hole. The first pipe of the floor drain lock nut is passed through to obtain the second through hole. The outer edge is placed on the top surface of the waterproof pan. The second pipe of the flange lock nut is sleeved on the outside of the second pipe. Then, the second pipe is moved upward along the height direction of the first pipe so that the top edge abuts against the bottom surface of the waterproof pan. The second sealing gasket is sleeved on the first pipe. Install the waterproof tray onto the deck and pass the first pipe through the first through hole; The drain pipe of the drain body is fitted onto the second sealing gasket, and the top surface of the waterproof edge is fixedly connected to the bottom surface of the deck. Place the water seal on the first pipe and attach it to the inner edge, then place the drain cover on the outer edge to complete the installation of the drain structure.

[0013] This invention discloses a water seal component within the first pipe of the drain lock nut in a marine integrated bathroom structure. This component forms a stable water seal cavity within the pipe, effectively preventing sewer odors and insects from entering the bathroom even during shipboard movement, meeting the hygiene requirements of enclosed marine spaces. A multi-layered sealing structure is constructed through the connection of the first and second sealing gaskets with the waterproof edge and the deck bottom, preventing water leakage from the bathroom into the gap between the waterproof tray and the deck, thus preventing corrosion and damage to the ship's deck due to water accumulation and extending the durability of marine facilities. The nested fixing design of the drain lock nut, flange lock nut, and drain body ensures stable installation of the drain between the waterproof tray and the deck. Even under vibration and shaking conditions during shipboard movement, the components are not prone to loosening or falling off, ensuring long-term reliable operation of the drain. The nested cooperation of the first and second pipes with the drain pipe, combined with the through-hole layout of the deck and waterproof tray, allows for rapid drainage of bathroom water, preventing the risk of slipping and falling due to wetness in the confined space of a marine bathroom.

[0014] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The following embodiments are used to illustrate this invention but should not be used to limit the scope of this invention.

[0022] The following is combined Figures 1 to 4 The present invention describes a drain structure applicable to a marine integrated bathroom. The bottom of the marine integrated bathroom consists of a waterproof tray 1 and a deck 2, with a set distance between the waterproof tray 1 and the deck 2. The deck 2 has a first through hole, and the waterproof tray 1 has a second through hole. The drain structure includes a drain lock nut 3, a flange lock nut 6, and a drain body 8. The drain lock nut 3 includes an outer edge, an inner edge, and a first pipe. The outer edge is connected to the top outer side of the first pipe, and the inner edge is connected to the top inner side of the first pipe. The first pipe is inserted into the second through hole. The outer edge is attached to the top surface of the waterproof tray 1. A drain cover plate 4 is provided on the top of the outer edge. A water seal 7 is provided inside the first pipe, and the water seal 7 is attached to and connected to the inner edge. The flange lock nut 6 includes a top edge and a second pipe. The top edge is connected to the top outer side of the second pipe. The second pipe is sleeved and connected to the outer side of the first pipe. The second pipe and the first pipe are fixedly connected. The top edge abuts against the bottom surface of the waterproof pan 1. A first sealing gasket 5 is provided between the outer edge, the top edge and the first pipe. The drain body 8 includes a waterproof edge and a drain pipe. The waterproof edge is connected to the top outer side of the drain pipe and to the bottom surface of the deck 2. The drain pipe is disposed in the first through hole and sleeved on the first pipe. A second sealing gasket 9 is disposed between the drain pipe and the first pipe.

[0023] Preferably, the water seal 7 inside the first pipe of the drain lock nut 3 can form a stable water seal cavity in the pipe. Even if the ship is rocking during navigation, it can effectively prevent sewer odors and insects from entering the bathroom, meeting the hygiene requirements of the enclosed space on board. The connection between the first sealing gasket 5 and the second sealing gasket 9, along with the waterproof edge and the bottom surface of the deck 2, creates a multi-layered sealing structure. This prevents water leakage from the bathroom into the gap between the waterproof tray 1 and the deck 2, preventing corrosion and damage to the ship's deck 2 due to water accumulation, and extending the durability of the ship's facilities. The nested fixing design of the drain lock nut 3, flange lock nut 6, and drain body 8 ensures the drain is stably installed between the waterproof tray 1 and the deck 2. Under the vibration and rocking conditions of ship navigation, the components are not easily loosened or detached, ensuring long-term reliable operation of the drain. The nested cooperation of the first pipe, the second pipe, and the drain pipe, combined with the through-hole layout of the deck 2 and the waterproof tray 1, can quickly drain water from the bathroom, preventing the risk of slipping due to wetness in the small space of the ship's bathroom.

[0024] In a preferred embodiment of the present invention, a drain structure suitable for marine integrated bathrooms is provided, such as... Figures 1 to 3 As shown, the waterproof tray 1 is recessed downwards at the position corresponding to the second through hole to form a first step, the outer edge is connected to the first step, the top surface of the drain cover 4 is flush with the top surface of the waterproof tray 1, and the top edge is fixedly connected to the bottom surface of the first step.

[0025] Preferably, the first step not only integrates the drain and the waterproof tray 1 visually, enhancing the overall aesthetics of the bathroom, but also effectively prevents debris from accumulating on the surface of the waterproof tray 1, avoiding blockages that could affect drainage. The fixed connection between the top edge and the bottom of the first step further enhances the stability of the drain structure, making it less prone to displacement during long-term use. Furthermore, this connection method also provides a buffering effect, reducing the impact of vibrations from ship navigation on the drain. During drainage, the recessed design of the waterproof tray 1 corresponding to the second through-hole better guides water flow to the drain, accelerating drainage and reducing the time water accumulates in the bathroom. Moreover, the first step also buffers and disperses water flow, reducing the impact of water on the internal structure of the drain and extending its lifespan. This structural design also facilitates daily cleaning and maintenance of the drain, allowing staff to easily inspect and clean the waterproof tray 1 and the drain, ensuring it remains in good working order.

[0026] Preferably, the first sealing gasket 5 is U-shaped. The first sealing gasket 5 is made of silicone. The U-shaped design of the first sealing gasket 5 allows it to fit tightly against the waterproof tray 1, ensuring a good seal at the connection between the drain lock nut 3, the flange lock nut 6, and the waterproof tray 1. The silicone material of the first sealing gasket 5 has a certain degree of elasticity, allowing it to deform and recover when compressed, further enhancing the reliability of the seal. During ship navigation, various bumps and swaying are encountered; the U-shaped first sealing gasket 5 can better adapt to this dynamic environment, maintaining a sealed state at all times. Moreover, the U-shaped design facilitates installation and disassembly, allowing workers to easily operate when the drain needs repair or gasket replacement, improving work efficiency.

[0027] Specifically, such as Figures 1 to 3 As shown, the inner edge includes an inclined guide surface and a horizontal mounting surface, with the water seal 7 mounted on the mounting surface. The inclined design of the guide surface guides water flow more smoothly into the water seal 7, preventing water accumulation in the waterproof tray 1 and reducing the possibility of odor generation and bacterial growth. When water impacts the guide surface, it flows quickly towards the water seal 7 along the inclined angle, improving drainage efficiency. The horizontal mounting surface provides a stable support platform for the water seal 7, ensuring it is firmly mounted and will not easily shake or shift. After the water seal 7 is mounted on the mounting surface, it effectively blocks odors and harmful gases from entering the room. The certain amount of water stored in the water seal 7 forms a barrier, preventing the backflow of odors and gases. At the same time, the water seal 7 also prevents small insects from entering the bathroom through the pipes, creating a more hygienic and comfortable environment for the marine integrated bathroom. When installing the water seal component 7, workers only need to place it stably on the scaffolding surface to complete the initial installation. Subsequent debugging and fixing work is also relatively simple. When it is necessary to replace or clean the water seal component 7, it can be easily removed from the scaffolding surface without damaging other structures of the floor drain.

[0028] Specifically, such as Figures 1 to 3As shown, the outer wall of the first pipe has external threads, and the inner wall of the second pipe has internal threads. The internal threads are screwed onto the external threads to securely connect the first and second pipes. This threaded connection method is not only easy to install—simply align the second pipe with the first pipe and tighten—but also provides excellent sealing. In the special environment of a marine bathroom, it effectively prevents water leakage from the pipe connection, avoiding water accumulation on the bathroom floor, affecting the user experience, or even damaging the bathroom structure. Simultaneously, the threaded connection also provides a certain degree of tightness, able to withstand water flow impacts and vibrations during daily use, ensuring the stability of the connection between the first and second pipes and preventing easy loosening. Furthermore, when pipe repair or replacement is needed, the second pipe can be easily removed from the first pipe by rotating it in the opposite direction, facilitating operation without causing significant damage to the pipes, improving repair efficiency, and reducing maintenance costs.

[0029] Specifically, such as Figures 1 to 3 As shown, the drain pipe is L-shaped. Sewage from the first pipe first enters the vertical section of the drain pipe, and then is discharged outward through the horizontal section of the drain pipe.

[0030] Specifically, the diameter of the first through hole is larger than that of the second through hole, facilitating the accurate insertion of the first pipe into the first through hole and improving the ease of connection between the drain lock nut 3 and the drain body 8. The top surface of the waterproof edge and the bottom surface of the deck 2 are connected by welding. The full welding connection between the top surface of the waterproof edge and the bottom surface of the deck 2 significantly improves the connection stability between the waterproof edge and the deck 2. The width of the waterproof edge is larger than the diameter of the first through hole. When the position of the first through hole deviates (≤5cm), the waterproof edge can be sealed from below, increasing the tolerance value for the opening of the first through hole and facilitating the adjustment of the drain pipe position according to the required drainage location.

[0031] Specifically, the water seal component 7 includes an inner water seal pipe and an outer water seal pipe. The top of the inner water seal pipe and the outer water seal pipe are connected, there is a gap between the inner water seal pipe and the outer water seal pipe, there is a gap between the inner bottom of the inner water seal pipe and the outer water seal pipe, and a water seal drain outlet is provided near the top of the outer water seal pipe.

[0032] This invention also provides a method for constructing a floor drain structure suitable for marine prefabricated bathrooms, wherein the construction method is performed using the floor drain structure described above, such as... Figures 1 to 3 As shown, it includes the following steps: The first through hole is opened on deck 2; The first sealing gasket 5 is connected to the waterproof pan 1 at the position corresponding to the second through hole. The first pipe of the drain lock nut 3 is passed through to obtain the second through hole. The outer edge is placed on the top surface of the waterproof pan 1. The second pipe of the flange lock nut 6 is sleeved on the outside of the second pipe. Then, the second pipe is moved upward along the height direction of the first pipe so that the top edge abuts against the bottom surface of the waterproof pan 1. The second sealing gasket 9 is sleeved on the first pipe. Install the waterproof tray 1 onto the deck 2, and pass the first pipe through the first through hole; The drain pipe of the drain body 8 is fitted onto the second sealing gasket 9, and the top surface of the waterproof edge is fixedly connected to the bottom surface of the deck 2. Place the water seal 7 on the first pipe and attach it to the inner edge, and place the drain cover 4 on the outer edge to complete the installation of the drain structure.

[0033] Preferably, after completing the installation of the above-mentioned floor drain structure, a sealing check of the entire floor drain structure is required. Using professional sealing testing tools, check the contact points between the first sealing gasket 5, the second sealing gasket 9, and each connecting part to see if there are any gaps or leaks. If any sealing problems are found, adjust the position of the sealing gaskets or replace them in time to ensure the good sealing performance of the entire floor drain structure. Next, conduct a drainage test. Inject a certain amount of water into the waterproof tray 1 and observe the drainage through the floor drain structure. Check whether the drainage is smooth and whether there is any blockage, and at the same time, pay attention to the working status of the water seal 7 to ensure that the water seal can effectively block odors. If slow drainage or blockage occurs during the drainage process, check the drain pipe, the first pipe, and other parts of the floor drain body 8, and remove any possible debris. After completing the drainage test and ensuring normal drainage, clean the entire construction area. Clean up the waste and debris generated during the construction process, keeping the deck 2 and the surrounding environment clean. At the same time, clean the floor drain cover 4 to ensure its appearance is clean and tidy.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
