The ship ballast water is an important substance for controlling the trim, draft, stability and stress of the ship. Generally, when a ship is loaded, as the load of the ship increases, the ship performs water discharge treatment, such as direct discharge, on the ballast water. Most of the south cargo ships carry a large amount of fresh water for ballasting, and the ships can only operate after the ships arrive at ports and the ballasting water is emptied. Such directly discharged fresh water ballast water is an extremely precious fresh water resource for northern or offshore island ports, and the ballast water is stored in the ballast tank for a long period of time, thereby causing a large number of germs to grow and also causing environmental impact. In order to recycle the fresh water ballast water of the ship, it is necessary to perform a water discharge treatment for the fresh water ballast water of the ship, and the ballast water after the treatment such as sterilization can be recycled or directly discharged, thereby not affecting the environment.

Further, considering that the receiving pipeline 10 is originally air-filled, when the ballast water is introduced into the water diversion branch 1, the receiving pipeline 10 is required to be continuously deflated, and considering that the consistency of the deflating position is beneficial to controlling the deflating.
The receiving line 10 is thus secured by means of a holder 15, which holder 15 can be secured to the deck 16 of the vessel, and which deck 16 is provided with holes 17.
The receiving line 10 is fixed by the holder 15 and the part of the holder 15 is lifted up so that this part becomes the highest position of the receiving line 10, so that the air in the receiving line 10 is discharged centrally there, wherein the holes 17 are the manholes, ventilation holes, in the deck 16 of the vessel. In addition, the receiving pipe 10 may be a hose which may be compressed before operation, so that the air originally contained in the receiving pipe may be very small, and the fixing device 15 may not be used, and may be selected according to actual situations.
Further, considering that the receiving pipe 10 needs to be continuously sealed from the outside after the air is exhausted, the preferred embodiment of the fixer 15 includes a supporting frame 19, a cavity 20 is provided on the supporting frame 19, two sides of the cavity 20 are detachably connected with the free end 33 and the receiving pipe 10 through an interface 21, a mounting groove is provided on the cavity 20, a movable member 23 is movably provided in the mounting groove, an upper through groove 24 is provided on the movable member 23, and a lower through groove 25 is provided on one side of the mounting groove close to the upper through groove 24; the movable part 23 is in the whole process of reciprocating sliding in the mounting groove, and the upper through groove 24 and the lower through groove 25 can be communicated, so that the inner cavity 22 of the cavity 20 is communicated with the atmosphere; or the upper and lower through slots 24, 25 can be offset to isolate the interior cavity 22 of the cavity 20 from the atmosphere. The other side of the mounting groove is movably provided with a locking sliding part 29, the movable part 23 is provided with a locking concave 32, and the locking concave 32 is used for matching with the locking sliding part 29 to lock the movable part 23 so as to maintain the dislocation state of the upper through groove 24 and the lower through groove 25. The installation groove is provided with a groove 31, the locking sliding piece 29 is embedded in the groove 31 to slide reciprocally along the extending direction perpendicular to the movable piece 23, the locking sliding piece 29 and the groove 31 are also provided with an elastic piece 30, and the bottom of the movable piece 23 is provided with a buoyancy piece 26.
The anchor 15 in this embodiment works in step 10 specifically in combination with the above-described operation method, and the specific working principle is as follows:
in step 10, before the operation of opening the water pump 2 to pump ballast water into the receiving pipeline 10 is performed, the interior cavity 22 of the cavity 20 is substantially air, at this time, the buoyancy member 26 at the bottom end of the movable member 23 is not subjected to the buoyancy force of the liquid, so that the movable member 23 slides to the lowest end where it can slide under the action of its own weight, at this time, the upper through groove 24 and the lower through groove 25 are communicated, and part of the upper through groove 24 is communicated with the atmosphere, so that the interior cavity 22 of the cavity 20 is communicated with the outside, and at this time, when water flow is introduced into the interior cavity 22 of the cavity 20, the gas in the interior cavity 22 of the cavity 20 can flow to the outside.
In step 10, when the water pump 2 is turned on and the operation of pumping ballast water into the receiving pipeline 10 by the water pump 2 is performed, since the inner cavity 22 of the cavity 20 is at a higher position, after the pipes on both sides of the inner cavity 22 of the cavity 20 are filled, the liquid level 18 in the inner cavity 22 of the cavity 20 starts to rise gradually, i.e. the state shown in fig. 3, and at this time, the buoyancy member 26 at the bottom end of the movable member 23 is not subjected to the buoyancy of the liquid, so that the inner cavity 22 of the cavity 20 is communicated with the outside.
The liquid level 18 in the inner cavity 22 of the cavity 20 continues to rise, and when the buoyancy member 26 begins to be subjected to the buoyancy of the liquid, the buoyancy force pushes the movable member 23 to rise gradually.
It is worth noting that the upper and lower through grooves 24 and 25 in this embodiment have two opposite "L" shapes, the lateral portions of which are widened, which has the advantage of always keeping the inner cavity 22 of the cavity 20 in communication with the outside during the initial sliding on the movable member 23, thus providing the maintenance of ventilation during sliding.
It can be seen that when the buoyancy member 26 (typically a bladder or foam) does not float to its highest point, the interior cavity 22 of the cavity 20 can always be deflated while being filled with water.
When the buoyancy member 26 floats to the highest point, the liquid level 18 in the inner cavity 22 of the cavity 20 can reach the highest point at the same time, the movable member 23 slides up to the highest position at the same time, and the upper through groove 24 and the lower through groove 25 are just staggered from each other, so that the inner cavity 22 of the cavity 20 is isolated from the outside air.
In addition, when the movable member 23 does not slide up to the highest position, the locking recess 32 on the movable member 23 is always staggered from the position of the locking slider 29, and the elastic member 30 is in a compressed state at this time, and when the locking recess 32 on the movable member 23 is aligned with the position of the locking slider 29, the elastic member 30 drives the locking slider 29 to move to the right side, so that the right end of the locking slider 29 is embedded into the locking recess 32, and thus the movable member 23 is always locked. The locking aims to prevent the movable member 23 from sliding up and down to communicate with the outside due to the fluctuation of the water level.
In order to limit the sliding travel of the movable piece 23, the utility model also provides a sliding groove 28 on the movable piece 23, and a hollow sliding protrusion 27 is arranged on the left side wall of the installation groove in a matched manner, and the movable piece 23 is limited by the cooperation of the sliding groove and the hollow sliding protrusion.
In this embodiment, the positions of the hollow slider 27 and the locking slider 29, the positions of the slide groove 28 and the locking recess 32 are partially overlapped, so that the space for arrangement is saved, and may not be overlapped in other embodiments.
Specifically, the interface 21 is a part of the fire-fighting connector, and can be matched with the free end 33 and the second fire-fighting connector 5 after the receiving pipeline 10 is disassembled, so that relatively stable quick disassembly and quick disassembly are realized.
When the primary ballast water discharge treatment is completed, the locking slider 29 is preferably hinged with a control link 34 for the convenience of restoring the locked movable member 23.
The position of the locking slide 29 can be quickly reset from the outside by pulling the control link 34 manually or by a machine. In particular, when the water in the pipe is completely discharged, the movable member 23 needs to be reset for the next use.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
