Embodiment Construction

[0018] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific implementation examples in order to express the structural features and specific applications of the present invention more clearly, but this should not limit the protection scope of the present invention.

[0019] Such as figure 1 As shown, the breathable cap of the novel ship cabin of the present embodiment comprises a base 1, an outer shell 2, an inner shell 3, and a float 4, and an outer chamber 5 is formed between the outer shell 2 and the inner shell 3, so that The inner space of the inner housing 3 forms an inner chamber 6, the floating ball 4 is placed in the inner chamber 6, an inner air inlet 7 is provided between the outer housing 2 and the base, and the outer chamber 5 communicates with the cabin of the ship through the inner air inlet 7, and a water inlet 8 is provided on the inner casing 3, and the water inlet 8 communicates with the inner cham...

Abstract

The invention discloses a novel ship cabin ventilation cap, comprising a base, an outer casing, an inner casing and a floating ball. An outer chamber is formed between the outer casing and the inner casing. The inner space of the inner casing forms an inner chamber. The floating ball is placed in the inner chamber. An inner air inlet is arranged between the outer casing and the base. The outer chamber communicates with a ship cabin through the inner air inlet. The inner casing is provided with a water inlet. The water inlet communicates with the inner chamber. A protective screen is arranged at the water outlet in the upper part of the inner chamber. A retaining ring is arranged on the periphery of the protective screen. The retaining ring is fixed to the upper part of the inner casing bybolts. The ball diameter of the floating ball is not less than the diameter of the water outlet. By adopting the ventilation cap, when the waterline floods the water inlet in the inner casing, the external seawater pressure causes the floating ball to automatically float to close the water outlet in the upper part of the inner casing, thus seawater can be quickly prevented from further permeatinginto the interior of the ship cabin, therefore the requirement of watertightness is met, and the ship maintains the buoyancy.

Description

technical field [0001] The invention belongs to the field of ventilating equipment for ship cabins, and in particular relates to a novel ship cabin ventilating cap suitable for the ship cabins of ships flying the Dutch flag. Background technique [0002] Vent caps for conventional ship cabins are only weathertight. That is, when the ship is damaged and the waterline is submerged to the weathertight opening, seawater enters the cabin through the weathertight opening. The flooding of the ship's cabin will cause the ship to tilt further, thereby further losing the buoyancy of the ship, which may eventually cause the ship to capsize completely. Contents of the invention [0003] According to the problems existing in the prior art, the present invention provides a novel ship cabin breathable cap, which can prevent seawater from further infiltrating into the ship cabin in time, thereby meeting watertight requirements and keeping the ship buoyant. [0004] To achieve the above ...
