Deck water leakage opening

Abstract

The invention discloses a deck water leakage opening, which comprises a cylindrical body, the cylindrical body is provided with a partition plate, a water leakage hole is formed in the middle of the partition plate, a floating ball and a guide device for limiting the floating ball to move up and down are arranged under the partition plate, and when water enters the lower portion of the partition plate, the floating ball can move upwards along the guide device under the action of buoyancy to abut against the lower portion of the partition plate to seal the water leakage hole. The deck water leakage opening is simple in structure; the floating ball accurately moves to the water leakage hole to be tightly attached to form sealing under the buoyancy of liquid and the guiding effect of the guide device, so that domestic sewage in the sewage collection cabinet is prevented from overflowing out of the water leakage hole to other cabins, and the situation that the comfort of crew is seriouslyaffected is avoided; and when a ship heeling accident happens, domestic sewage in the sewage collection cabinet can be prevented from flowing out of the water leakage hole to increase overturning moment, and the safety of the ship is improved.

Description

technical field [0001] The invention relates to a floor drain sealing device for sewers, in particular to a watertight deck drain used for draining water in shower rooms of ships and offshore facilities. Background technique [0002] In order to improve the comfort and convenience of the crew, whether it is an ocean-going ship or a short-distance civilian transport ship, it is often necessary to arrange a toilet or a shower near the cabin. Below the watertight deck, there is usually a cabin for the crew, for which there are often toilets or showers below the watertight deck. Its position is too low to discharge its domestic sewage directly overboard. It is necessary to set up a sewage collection cabinet under the floor of the toilet or shower, and set a deck leak on the floor above the sewage collection cabinet to collect shower water , pipeline leakage, domestic sewage from urinals and deck flushing water, etc. [0003] Due to the extremely limited space under the waterti...

AI Technical Summary

Problems solved by technology

The existing deck leaks are of fixed type, such as figure 2 As shown, when the liquid level in the sewage collection tank is high or the hull shakes, the sewage in the sewage collection tank will flow back through the deck leak and overflow into the crew cabin or other living cabins, seriously affecting the comfort of the crew. sex

In addition, when the cabin is damaged and the ship has a heeling accident, the domestic sewage in the sewage collection tank will overflow from the leak and flow to the lower side of the cabin, thereby increasing the ship's lateral overturning moment and increasing the risk of the ship's capsizing. great security risk
