Description
Technical Field
The invention relates to the technical field of ship transportation, in particular to a marine air pipe head structure convenient to maintain.
Background
The air pipe head is mainly applied to various ships and is used for keeping the ventilation pipeline smooth, and the air pressure in the cabin is close to the atmospheric pressure through ventilation and air suction so as to ensure that the pressure of the cabin does not exceed the design pressure of the cabin. When the ship body inclines or meets wind and waves, water flows into the air inlet, the buoy in the air pipe head quickly floats under the action of buoyancy force to be attached to the sealing ring to close the air-permeable pipeline, and therefore water is prevented from entering the cabin; when the water flows out, the buoy falls to the original position, and the ventilation pipeline is continuously unblocked.
The conventional air pipe head is generally rectangular and made of iron materials, so that the air pipe head is large in size and weight, difficult to carry and capable of increasing the weight of a ship. The buoy is usually in a metal floating cake shape, floats and falls off at intervals along with inflow and outflow of water, often collides with the bottom of the sealing cover or the switching cavity, and is easy to crack. In order to ensure that the buoy and the sealing ring are accurately attached, a positioning device is usually arranged in the air pipe head, the structure is complex, the maintenance is inconvenient, the buoy can be influenced to float in time when the positioning device is rusted or fails, and the ventilation channel cannot be closed in time. The protective net of the air pipe head is usually arranged outside the air pipe head and is easily wound by sea grass and damaged by sea birds.
Disclosure of Invention
The marine air pipe head structure is simple in structure, and when water is poured in, the accumulation of water can be effectively sealed and blocked; and can effectively keep the ventilation pipe unobstructed.
The invention is realized by the following technical scheme: an air pipe head structure for a ship convenient to maintain comprises a cover body, a shell and a base which are sequentially arranged from top to bottom; the cover body is provided with a through hole, and the shell is internally provided with an inner cavity communicated with the through hole; the base is provided with a channel communicated with the inner cavity; the cover body is round and is curled inwards to form a sealing ring supporting structure, and a sealing ring is arranged on the sealing ring supporting structure; the inner cavity is internally provided with a floating body capable of floating up and down, the floating body is of a spherical structure, and the diameter of the floating body is slightly smaller than the inner diameter of the inner cavity.
Among the above-mentioned technical scheme, through-hole, inner chamber and the passageway three in lid, casing and the base link up each other, can effectively keep unobstructed of permeability cell. Simultaneously, when water pours into, the body can cooperate with the sealing washer and prevent the accumulation of water.
In a further technical scheme, a breathable film is arranged on the through hole.
In a further technical scheme, a floating body blocking piece is arranged on the base, and the floating body blocking piece extends upwards from the base to form an arc-shaped wall capable of partially blocking the floating body.
In a further technical scheme, the number of the arc-shaped walls is 2, and the arc-shaped walls are symmetrically arranged.
In a further technical scheme, the channel is narrowed from the outside to the inside towards the direction close to the inner cavity axis.
In a further technical scheme, the floating body is of a double-layer structure and comprises an inner layer formed by hard materials inside and an outer layer formed by soft materials outside.
Compared with the prior art, the invention has the following advantages and beneficial effects: the marine air pipe head has a simple structure, and can effectively seal and block the accumulation of water when water is poured in; and can effectively keep the ventilation pipe unobstructed.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
as shown in fig. 1, an air pipe head structure for a ship, which is convenient to maintain, includes a cover body 1, a shell body 2 and a base 3, which are sequentially arranged from top to bottom; the cover body is provided with a through hole 4, and the shell is internally provided with an inner cavity 5 communicated with the through hole; the base is provided with a channel 6 communicated with the inner cavity; the cover body is round and is curled inwards to form a sealing ring supporting structure 7, and a sealing ring 8 is arranged on the sealing ring supporting structure; a floating body 9 capable of floating up and down is arranged in the inner cavity, the floating body is of a spherical structure, and the diameter of the floating body is slightly smaller than the inner diameter of the inner cavity.
In the embodiment, the through holes, the inner cavity and the channel in the cover body, the shell and the base are communicated with each other, so that the smoothness of the vent pipe can be effectively kept. Simultaneously, when water pours into, the body can cooperate with the sealing washer and prevent the accumulation of water.
And a breathable film 10 is arranged on the through hole. The base is provided with a floating body blocking piece 11 which extends upwards from the base to form an arc-shaped wall 12 capable of partially blocking the floating body. The number of the arc-shaped walls is 2, and the arc-shaped walls are symmetrically arranged. The channel narrows from the outside to the inside towards the direction close to the axis of the lumen.
