Description
Technical Field
The invention relates to the technical field of ships, in particular to a ship anti-heeling system and a ship with the same.
Background
When the engineering ship is lifted for operation, the hoisting crane can generate a transverse tilting moment on the ship within a certain radius range, so that the ship transversely tilts. In order to avoid the capsizing of the ship, an anti-heeling water system is generally arranged on the ship, and the anti-heeling moment of the ship caused by the hoisting weight is offset by allocating seawater in an anti-heeling cabin on the left side and the right side.
At present, the anti-list water system of boats and ships has following problem at least:
firstly, in the existing anti-heeling cabin, an air pipe is directly led out from the top of the side wall of the anti-heeling cabin. Since the air tube needs to be upwardly ventilated, the end of the air tube is thus upwardly inclined at a certain angle. In addition, due to the factors such as the limitation of the opening of the hull structure and the limitation of the welding construction space, the actual position of the air pipe on the side wall is lower, the actual storage height of the anti-heeling cabin is lower, and the actual storage capacity of the anti-heeling cabin is reduced.
And secondly, the discharge capacity of the anti-heeling pump is generally determined according to the allocated water quantity at the corresponding time of the hoisting operation, and if the water quantity required to be allocated in unit time is larger, the discharge capacity of the anti-heeling pump is naturally increased correspondingly. The large-scale hoisting engineering ship has higher hoisting capacity, the displacement of the anti-heeling pump is often larger, and the drift diameter of the matched anti-heeling pipeline is naturally larger.
According to the relevant specification requirements, for all tanks which can be filled by means of an inboard or shore pump through the injection manifold, the total cross-sectional area of the air ducts of each tank should be at least 25% greater than the effective cross-sectional area of the respective injection duct. Therefore, the air pipe of the anti-heeling cabin of the large-scale crane ship has larger size and larger occupied area, and is not beneficial to the operation of hoisting equipment.

Detailed Description
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention.
Referring to fig. 1 to 3, the anti-heeling system for a ship of the present invention includes two anti-heeling compartments 100, an air tube 300, a level switch 400, and a float ball device 500.
Referring to fig. 1, two anti-list tanks 100 are connected to each other by an anti-list pump and are respectively disposed at both sides of a hull 200. Preferably, two anti-list tanks 100 are located port and starboard, respectively. The two anti-heeling tanks 100 intermodulate and dial seawater through anti-heeling pumps to balance the ship.
Referring to fig. 2, an air tube 300 is inserted through the side wall of the anti-list cabin 100. Preferably, the air tube 300 is threaded through the anti-list cabin 100 side wall by a cabin-through sleeve 310. Also, the end of the air pipe 300 is bent upward, and "upward" in this case means a direction toward the air when the ship normally sails. The end of the air tube 300 refers to the end of the air tube 300 that is located inside the anti-list cabin 100. Also, the end of the air tube 300 is proximate to the top of the anti-list cabin 100.
Referring to fig. 2, a level switch 400 is provided on the anti-heel chamber 100 side wall. The level switch 400 is at a lower level than the level of the end of the air tube 300. In this embodiment, in order to ensure the sensing accuracy of the liquid level switch 400, the liquid level switch 400 should be lower than the end of the air tube 300, and the horizontal position of the liquid level switch 400 should be close to the horizontal position of the end of the air tube 300 as much as possible, so as to ensure the overall water storage capacity of the anti-heeling compartment 100.
Referring to fig. 3, the float ball device 500 is located in the anti-list chamber 100 and communicates with the lower end of the air tube 300. The floating ball device 500 includes a cylinder 510, a floating body 520 movably disposed in the cylinder 510, a stopper 530 disposed at an upper end of the cylinder 510, and a connection pipe 550.
In this embodiment, the upper end of the connection pipe 550 is communicated with the lower end of the air pipe 300, the lower end of the connection pipe 550 is connected with the limiting seat 530, and the lower end of the cylinder 510 is provided with the limiting plate 540. The limiting seat 530 includes a cylindrical limiting portion 531 inserted inside the cylinder 510, the lower end of the cylindrical limiting portion 531 is an inclined surface 532, the inclined surface 532 extends from outside to inside, where "outside" in "from outside to inside" refers to a side close to the inner wall of the cylinder 510, and "inside" refers to a side far away from the inner wall of the cylinder 510. The floating body 520 is a sphere.
Referring to fig. 3, a first flange 560 is disposed at the lower end of the connecting pipe 550, the limiting seat 530 includes a mounting portion 533, a second flange 570 is disposed at the upper end of the cylinder 510, and the first flange 560, the mounting portion 533 and the second flange 570 are sequentially disposed from top to bottom and connected by bolts. The "up" direction is the direction toward the air when the ship normally sails, and the "down" direction is the opposite direction to the "up" direction.
When the floating body 520 is lifted due to the buoyancy, the floating body 520 abuts against the stopper 530 and blocks the seawater from flowing into the air tube 300 through the cylinder 510. In this embodiment, the floating body 520 is a sphere, and the floating body 520 and the inclined plane 532 are engaged with each other to block the communication of the seawater between the cylinder 510 and the connection pipe 550. However, it should be noted that the floating body 520 may have any shape other than a spherical shape, and the lower end of the cylinder stopper 531 may not necessarily be an inclined surface as long as they are fitted to each other. However, since the floating body 520 floats on the seawater and thus is easily tumbled, it is preferable that the floating body 520 is a sphere.
Referring to fig. 2, the air tubes 300 extend from the anti-list cabin 100 side walls to the edges of the deck 210 of the hull 200. If the air ducts are still threaded from the upper end of the anti-list bin 100, the section of the air duct outside the anti-list bin 100 must be present on the deck 210 and the location is difficult to control. Accordingly, the air tubes 300 extend from the anti-list cabin 100 side walls, bringing the air tubes 300 to the edges of the deck 210 of the hull 200, thereby increasing the available area of the deck 210. However, since the air pipe 300 is introduced from the side wall of the anti-heeling chamber 100, the seawater storage capacity of a part of the anti-heeling chamber 100 is inevitably sacrificed, but the defect can be fully overcome by matching with the floating ball device 500, so that the working area of the deck is ensured, and the seawater storage capacity of the anti-heeling chamber 100 is improved.
In operation, the anti-heel chamber 100 uses an anti-heel pump to pump seawater. After the seawater enters the anti-heeling chamber 100 through the anti-heeling pump, the water level of the seawater in the anti-heeling chamber 100 continuously rises. When the seawater rises to the floating ball device 500, the seawater flows into the air pipe 300 through the floating ball device 500, and simultaneously the floating body 520 rises together with the seawater, and when the floating body 520 rises to abut against the limit seat 530 due to the buoyancy, the floating body 520 blocks the seawater from flowing into the air pipe 300 through the cylinder 510, and at this time, a part of the seawater is stored in the air pipe 300. The seawater then rises until stopped at level switch 400.
The ship anti-heeling system realizes seawater allocation to resist heeling through the two anti-heeling cabins 100, the air pipe 300, the liquid level switch 400 and the floating ball device 500. Meanwhile, a portion of seawater is received in the air pipe 300 by the float device 500, thereby improving the seawater storage capacity of the anti-list cabin 100. In a preferred embodiment of the present invention, a ship, especially a crane ship, includes the anti-heeling system of the present embodiment, and the ship uses the anti-heeling system to realize the anti-heeling function, so as to meet the requirement.
The above embodiments are further described in the present invention, but it should not be understood that the scope of the above subject matter is limited to the above embodiments, and all the technologies realized based on the above embodiments are within the scope of the present invention.
