Detailed Description
The embodiments of the present invention are further described below with reference to the drawings.
Example 1:
referring to fig. 1 to 3, a skirt cover for a ship air bottom comprises an air pump 1, an air pipe 2, a binding band 3, a ship 4, an air bag skirt 5 and a cover bottom 6; the air bag apron 5 is arranged around the sleeve bottom 6, one end of the binding band 3 is connected around the sleeve bottom 6, the other end of the binding band 3 is fixed on a ship board railing and a bulbous bow 7, the binding band 3 of the bulbous bow 7 can be annular, the annular binding band 3 is directly sleeved on the bulbous bow 7 firstly when in use, then the binding bands 3 on two sides are bound on a ship board, the sleeve bottom 6 is fixedly arranged on the horizontal surface of the bottom of the ship 4, and the air bag apron 5 is connected with the air pump 1 through the air pipe 2.
An air pipe 2 is arranged in the air bag apron 5, and the other end of the air pipe 2 is connected with the air pump 1.
When the wind wave is small to a certain degree, the air pump 1 is used for inflating the air bag apron 5, so that the apron can be erected around the sleeve bottom, the air pump 1 is used for inflating the air bag apron 5 to discharge water at the bottom of the ship, so that the air bag apron 5 at the bottom of the ship is filled with air to form an air cushion layer, and the resistance can be reduced because the bottom of the ship is not contacted with the water and the air layer is contacted with the water when the ship sails. The air pump 1 can pump air in the air cushion layer in real time according to the loss of air in the apron at the bottom of the ship, so that the existence of the air cushion layer is ensured.
Example 2:
referring to fig. 4 to 6, the jacket bottom 6 covers the bottom of the ship 4.
The middle part of the sleeve bottom 6 is provided with a hollow part which is of an oval structure, the sleeve bottom 6 is sleeved at the bottom of the ship 4 in a sealing mode, so that materials can be saved, but the sleeve bottom 6 is still mostly arranged at the bottom of the ship, so that the sealing effect can be still good, and the novel marine boat is suitable for large ships 4.
The sleeve bottom 6 around be equipped with piece formula apron 8, piece formula apron 8 constitute by rigid material, the inboard of piece formula apron 8 have spacer 9, one end of spacer 9 with sleeve bottom 6 connect, the other end of spacer 9 with piece formula apron 8 connect, the length of spacer 9 let piece formula apron 8 with the bottom of ship 4 between the contained angle be less than 90 degrees. That is, the length of the spacer 9 is less than the angle between the sheet apron 8 and the bottom of the boat 4, and the length of the spacer 9 is tightened when the angle is 90 degrees. So that no air leakage occurs due to the angle between the sheet apron 8 and the bottom of the boat 4 being greater than 90 degrees.
The air bag apron 5 is also internally provided with a transverse apron 10, and a space enclosed by each transverse apron 10 and the surrounding sheet type apron 8 is internally provided with an air pipe 2 and is connected with the air pump 1, so that two air cushions are formed, and because the two air pumps 1 supply air to the two air cushion layers, a better air supply effect can be achieved when the ship pitches.
When the air pump is used, the sheet type apron 8 is inflated by the air pump 1, so that the apron at the bottom of the ship is full of air, the sheet type apron 8 can stand along with the air inflated at the bottom of the ship, an air cushion layer can be formed at the bottom of the ship, and the resistance can be reduced when the ship sails.
Referring to fig. 7, a sheet skirt 8 made of a soft material is connected below the air bag skirt 5 to form a double-layer skirt structure, a spacer 9 is arranged on the inner side of the sheet skirt 8, one end of the spacer 9 is connected with the sole 7, and the other end of the spacer 9 is connected with the sheet skirt 8. The length of the spacer 9 ensures that the included angle between the sheet type apron 8 and the bottom of the ship 4 is less than 90 degrees. That is, the length of the spacer 9 is less than that when the angle between the sheet apron 8 and the bottom of the boat 4 is 90 degrees, the length of the spacer 9 is tightened.
With the double-layer apron, when the ship 4 is horizontal, the sheet-type apron 8 on the lower layer horizontally floats at the bottom of the ship, so that the apron is not high, the resistance can be reduced, and when the ship body pitches or rolls, the sheet-type apron 8 can stand along with the gas to prevent the gas from overflowing.
The sheet skirt 8 at the aft end of the vessel 4 must be made of a floatable material or a floatable material may be secured to the end of the sheet skirt 8 so that the sheet skirt 8 floats above the water surface at the bottom of the vessel. Moreover, since the aft apron is subjected to rearward water impact forces, the spacers 9 may also be resilient, which may be more effective.
Of course, the floatable plate type apron 8 can be used on both sides of the ship body.
The transverse skirt 10 may also be used in the air bag skirt 5. The sleeve bottom 6 in the air bag apron 5 can also be hollowed out. The hardness of the sheet type apron 8 can be determined according to the requirement.
The transverse apron 10 can be an air bag apron 5, or a sheet apron 8, or a double-layer apron.
The bottom 6 can also be fixed by magnet at the bottom of the ship, or by hook at the bottom of the ship and hook the bottom. The periphery of the sleeve bottom 6 can be provided with steel wires, so that the effect of better stress is achieved.
Both the air bag apron and the sheet apron can be covered on the outside with a hard material or can be made of a hard material, so that better performance is achieved.
In conclusion, the invention is suitable for various ship bodies in the prior art, and only a small amount of gas is supplemented in the apron at the bottom of the ship, so the cost and the energy consumption can be effectively reduced, and the maintenance is convenient.
Because the real ship body can be a ten thousand ton seagoing vessel, the air pump and the apron are relatively small, for the sake of clear performance, the air cushion apron and the like in the attached drawings are not in proportion, and thus the real ship body cannot be true or the effect cannot be negative.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification, or any direct or indirect application attached to other related technical fields, are included in the scope of the present invention.
