Description

Technical Field

[0001] The utility model relates to the technical field of drainage of ship sanitary units, and particularly to a concealed drainage structure of a ship sanitary unit. Background Technique

[0002] The ship sanitary system is an important place for maintaining personal hygiene and health on various ships, including military ships, boats, drilling platforms, etc. It is an indispensable part of the living cabins and an important part of the ship sanitary system. The structure of the sanitary unit consists of a steel chassis, wall panels, a ceiling and internal equipment, and is usually divided into a toilet area, a wash area and a shower area inside. Usually, the unit design is carried out according to the cabin layout plan provided by the shipyard. After being manufactured and passing the factory acceptance, it is packed and shipped to the shipyard and directly hoisted and installed. The drainage system of the ship sanitary unit generally has two outlets, namely the grey water drainage outlet and the sewage drainage outlet. The water discharged from the grey water drainage outlet mainly comes from the floor drains in the unit. Generally, there are two floor drains in the unit, one in the shower area and one in the wash area. The sewage drainage outlet mainly comes from the drainage of the toilet in the unit. The unit toilet is generally a wall-mounted gravity toilet or a vacuum toilet, and a round hole is opened on the unit wall panel for the drainage of the toilet.

[0003] At present, the drainage structure of the ship sanitary unit is buried in the base of the sanitary unit, and some drainage structures use the decorative layer to completely seal the surface of the base of the sanitary unit to ensure the concealment of the drainage structure. However, when any link in the drainage structure has a problem, the maintenance personnel cannot open the decorative layer in time for maintenance. In order to ensure the normal use of the ship passengers, the malfunctioning sanitary unit will be closed, thus reducing the usability of the sanitary units on the ship. It is worth noting that the sanitary units on the ship are relatively scarce in themselves. If too many sanitary units are closed, it will cause discomfort to many ship passengers. In addition, if the drainage structure in the sanitary unit can be repaired in time, the concealment and sealing and odor prevention of the drainage structure in the sanitary unit will need to be solved.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment 1:

[0024] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a concealed drainage structure for a ship sanitary unit, including a bottom base 1 of the sanitary unit, unit wall panels 2 fixedly connected to the four sides of the bottom base 1 of the sanitary unit, a decorative layer 3 fixedly installed on the surface of the bottom base 1 of the sanitary unit, a sewage drain outlet 4 opened on the surface of the unit wall panel 2 in the toilet area, a sewage drain pipe 5 fixedly connected to the toilet at the sewage drain outlet 4, a first floor drain opening 6 and a second floor drain opening 7 respectively opened on the surface of the decorative layer 3 in the shower area and the washbasin area, a water seal floor drain 8 for preventing backflow is inserted into the first floor drain opening 6 and the second floor drain opening 7, the lower ends of the water seal floor drains 8 are respectively fixedly connected to a drainage structure formed by a concealed first grey water branch pipe 10, a second grey water branch pipe 11 and a main grey water drain pipe 13, sealing sleeves 9 are respectively sleeved and connected at the joints of the water seal floor drains 8 and the first grey water branch pipe 10 and the second grey water branch pipe 11, a grey water drain outlet 12 for inserting the main grey water drain pipe 13 is opened on one side surface of the bottom base 1 of the sanitary unit, a disassembly groove 18 and an installation groove 21 for hiding the drainage structure are opened on the surface of the decorative layer 3, a disassembly plate 19 and a sealing plate 26 are inserted and fitted in the disassembly groove 18, the sealing plate 26 is fitted and arranged around the groove wall of the disassembly groove 18, the disassembly plate 19 covers and fits the two vertical surfaces of the sealing plate 26, and an installation groove plate 22 and a hidden cover plate 24 are inserted into the installation groove 21.

[0025] More specifically, in this embodiment, the sewage drain pipe 5 connected to the wall panel 2 of the toilet unit will directly discharge sewage outward through the sewage drain opening 4. The water-sealed floor drain 8 inserted into the first floor drain opening 6 and the second floor drain opening 7 in the shower area and the wash area is safely sealed, preventing phenomena such as backwater and foul odor from entering the sanitary unit on the ship, ensuring fresh air in the sanitary unit, improving the sealing and odor prevention effect at the drainage part of the sanitary unit on the ship, and the water-sealed floor drain has a gravity core, which is permanently stable and has a long service life. The sealing sleeve 9 ensures the sealing performance between the water-sealed floor drain 8 and the first gray water branch pipe 10 and the second gray water branch pipe 11 connected thereto. The first gray water branch pipe 10 converges the gray water in the wash area into the second gray water branch pipe 11, and the second gray water branch pipe 11 converges the gray water in the shower area together with the gray water in the wash area into the total gray water drain pipe 13. Finally, the gray water is uniformly discharged through the total gray water drain pipe 13 in the gray water drain opening 12.

[0026] The sealing plate 26 where the disassembly groove 18 is fitted with the disassembly plate 19 can effectively block the gap between the disassembly plate 19 and the disassembly groove 18, thereby avoiding the phenomenon that the odor at the drainage structure is emitted to the decorative layer 3, and further improving the sealing and odor prevention effect at the drainage part of the sanitary unit on the ship.

[0027] Furthermore, one end of the first gray water branch pipe 10 is connected and communicated with the pipe wall of the second gray water branch pipe 11. A one-way valve 14 is sleeved outside the second gray water branch pipe 11 away from the connection of the first gray water branch pipe 10 and the second gray water branch pipe 11. A double-row fixing frame 16 fixed to the inner wall of the sanitary unit base 1 is fixedly sleeved together at the parallel part of the first gray water branch pipe 10 and the second gray water branch pipe 11, and single-row fixing frames 15 fixed to the inner wall of the sanitary unit base 1 are respectively fixedly sleeved at the non-parallel parts of the first gray water branch pipe 10 and the second gray water branch pipe 11.

[0028] It should be noted that the one-way valve 14 ensures that the gray water flows in the same direction at the confluence of the wash area and the shower area. The parallel first gray water branch pipe 10 and the second gray water branch pipe 11 fixed by the double-row fixing frame 16 can strengthen the connection and fixation of the two branch pipes. At the non-parallel parts, the single-row fixing frame 15 can also separately fix the first gray water branch pipe 10 and the second gray water branch pipe 11 on the inner wall of the sanitary unit base 1.

[0029] Furthermore, the installation groove plates 22 are integrally connected to the two disassembly ends on both sides of the disassembly plate 19. Bolts 23 are threadedly fixed between the installation groove plates 22 and the installation grooves 21. The hidden cover plate 24 is inserted and covered on the upper surface of the installation groove plates 22, and notch openings 25 convenient for buckling out are provided on the surface of the hidden cover plate 24.

[0030] It should be noted that, first, the hidden cover plate 24 inserted in the installation groove 21 is removed by buckling through the notch 25, and then the bolt 23 between the installation groove plate 22 and the installation groove 21 is removed by threading, so that the disassembly plate 19 can be disassembled. The covering of the hidden cover plate 24 well covers the connection between the disassembly plate 19 and the decorative layer 3, achieving the purpose of hiding the drainage structure of the ship sanitation unit, ensuring that the drainage structure is convenient for maintenance and improving its hiding effect.

[0031] Embodiment 2, on the basis of the above embodiment:

[0032] Furthermore, a first waterproof platform 17 is provided on the surface of the decorative layer 3 in the shower area. The disassembly plate 19 extends to the outer sides of both sides of the first waterproof platform 17, and second waterproof platforms 20 that fit between the notches of the first waterproof platform 17 are attached to the two side surfaces of the disassembly plate 19.

[0033] More specifically, in this embodiment, the first waterproof platform 17 in the shower area prevents the gray water in the shower area from flowing around, ensuring that the gray water in the shower area can only be discharged through the first floor drain opening 6. The second waterproof platforms 20 added between the first waterproof platforms 17 also prevent the phenomenon that if the disassembly plate 19 is damaged in the shower area, the seal between the disassembly plate 19 and the decorative layer 3 is broken, while strengthening the single-flow drainage in the shower area.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
