Description
Technical Field
The invention relates to the technical field of ships, in particular to a floor drain for a ship.
Background
A accommodation for a crew is usually arranged below the watertight deck, the accommodation is low, domestic sewage cannot be directly discharged out of the accommodation, a sewage collecting cabinet is arranged below a floor of a toilet or a shower room, and a deck water leakage port is arranged above the sewage collecting cabinet and used for collecting shower water, pipeline water leakage, domestic sewage of a urinal, deck flushing water and the like. Because space under watertight deck is extremely limited, consequently, sewage collection cabinet height size is very little, and its storage liquid level often is close sewage collection cabinet top easily, and when the liquid level in the sewage collection cabinet was higher or the hull takes place to rock, sewage in the sewage collection cabinet will be through deck drain port department reverse irrigation overflow entering into crewman's accommodation or other living cabins, seriously influences crewman's travelling comfort.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide the marine floor drain which can prevent sewage in the sewage collecting cabinet from reversely filling and overflowing into a cabin of a crew or other living cabins and improve the living comfort of the crew.
In order to achieve the purpose, the technical scheme adopted by the marine floor drain is as follows:
the utility model provides a marine floor drain, include the sleeve with deck rigid coupling, telescopic top is provided with the filter plate, the center of filter plate is provided with vertical decurrent screw rod, the lower part of screw rod has cup jointed the decurrent movable barrel of opening, the through-hole that the screw rod passed is seted up to the movable barrel, through-hole and screw rod clearance fit, movable barrel top is provided with the first piece that keeps off with the screw rod rigid coupling, movable barrel inner chamber is provided with the second piece that keeps off with the screw rod rigid coupling, movable barrel is movable between first fender piece and second fender piece, the bottom of first fender piece is provided with the first sealing member with movable barrel top lateral wall complex, the outer peripheral surface of movable barrel is provided with the first conical surface of outwards diverging, sleeve inner peripheral surface is provided with the second conical surface with first conical surface complex, the top of second conical surface is provided with the second sealing member, the marginal integrated into one piece of movable barrel top lateral wall has the boss with second sealing member complex. Under normal condition, the movable barrel is in the lower position because of self gravity, and sewage flows into the sewage collection cabinet through the clearance and the through-hole between first conical surface and the second conical surface, and when sewage is reverse irritated, sewage promotes the upward movement of movable barrel, and the top lateral wall of movable barrel contradicts first sealing member, and the boss contradicts second sealing member, blocks that sewage overflows and enters into crewman's accommodation or other living cabins.
Preferably, a plurality of floating balls are arranged between the second blocking piece and the inner side wall of the top of the movable barrel. When sewage is reversely filled, the floating ball pushes the movable barrel in advance, before the sewage reaches the top wall of the movable barrel, the top outer side wall of the movable barrel is abutted against the first sealing element, the boss is abutted against the second sealing element, and meanwhile, the floating ball provides certain buoyancy, so that the top outer side wall of the movable barrel is tightly attached to the first sealing element, the boss is tightly attached to the second sealing element, and accordingly overflow of sewage can be better prevented from entering a crew accommodation or other living cabins.
Preferably, the inner circumferential surface of the movable cylinder is provided with a third conical surface parallel to the first conical surface. The third conical surface guides the reverse-filling sewage into the top wall of the movable cylinder, and meanwhile, the third conical surface increases the stressed area of the movable cylinder, so that the sewage just enters the movable cylinder and can push the movable cylinder to move upwards, and the water leakage gap is closed timely.
Preferably, the bottom of the filter plate is provided with an annular positioning boss matched with the inner peripheral surface of the sleeve. The annular positioning boss is convenient for assembling the filter plate and the sleeve.
Preferably, a third seal is provided between the sleeve and the deck. The third seal blocks the ingress of sewage from the gap between the sleeve and deck into the crew quarters or other living quarters.
Preferably, the first sealing element comprises a first O-shaped ring, the bottom surface of the first O-shaped ring is integrally formed with a plurality of first annular protrusions sleeved with the annular rings, and the cross section of the first annular protrusions is triangular. The tip of the first annular protrusion with the triangular section is in contact deformation with the outer side surface of the top of the movable cylinder body, a certain stroke is provided, the boss is guaranteed to abut against the second sealing piece, and the first annular protrusion is clung to the outer side surface of the top of the movable cylinder body after deformation, so that the assembly difficulty is reduced.
Preferably, the second sealing member comprises a second O-shaped ring, and a second annular protrusion is integrally formed on the inner side wall of the second O-shaped ring. The second annular protrusion improves the strength of the second O-shaped ring, so that the second O-shaped ring is not easy to warp, such as tilting, and tightness of the fit between the second O-shaped ring and the boss is ensured.
Compared with the prior art, the invention has the following advantages:
1. when sewage is reversely irrigated, sewage enters the movable barrel along the third conical surface, meanwhile, the movable barrel is pushed to move upwards, under the action of the floating ball, the outer side wall of the top of the movable barrel is abutted against the first sealing element before the sewage reaches the top wall of the movable barrel, the boss is abutted against the second sealing element, and meanwhile, the floating ball provides certain buoyancy, so that the top surface of the movable barrel is tightly attached to the first sealing element and the second sealing element, and further, the overflow of the sewage into a accommodation cabin of a crew or other living cabins can be better prevented, and the living comfort of the crew is improved.
2. The through hole of the movable barrel is in clearance fit with the screw rod, the screw rod does not restrict the movable barrel, and the movable barrel is automatically centered in the sleeve under the cooperation of the first conical surface and the second conical surface in the rising process of the movable barrel, so that the edge of the outer side surface of the top of the movable barrel is ensured.
3. The first annular protruding tip of triangle-shaped cross-section and movable barrel top lateral surface contact deformation have certain stroke, when guaranteeing that the boss contradicts the second sealing member, first annular protruding is hugged closely with movable barrel top lateral surface after warping to the assembly degree of difficulty has been reduced, and the second annular protruding intensity that has improved the second O type circle makes the difficult deformation such as take place perk of second O type circle, guarantees the tightness of second O type circle and boss laminating.
