Description

Technical Field

[0001] The utility model belongs to the technical field of marine engineering, and particularly relates to an automatic control anti-rolling device for a ship ballast water tank. Background Art

[0002] When a ship is docked or sailing at a pier, it may be affected by wind, waves and currents, causing roll, pitch, heave and other movements. Among them, roll movement is the most significant and has a great impact on ship operations and crew comfort. For liquid cargo ships, when the swaying is large, it will also aggravate the swaying of the liquid tank and affect the safety of the ship. Therefore, a roll reduction device is usually installed on the ship to slow down the roll movement of the ship. The commonly used ship roll reduction device is a passive roll reduction water tank. The water tank is U-shaped, and the two ends of the water tank are located on the side of the ship. An appropriate amount of water is injected into the tank. The physical movement of the water in the water tank caused by the roll movement of the ship itself is used to generate a stabilizing torque.

[0003] A Chinese patent with publication number CN214296364U discloses a ship roll reduction device, which includes: a ship body, two roll reduction units, a detector and a control unit; the roll reduction unit and the detector are electrically coupled to the control unit; the first roll reduction unit includes: a second water tank, a first support frame, a first water bag and a first water pump, the second roll reduction unit includes: a first water tank, a second support frame, a second water bag and a second water pump, the first side wall of the ship body has a first water tank, the outer surface of the first side wall of the ship body has a first support frame, and the first water bag is fixed on the support frame.

[0004] Although the ship roll stabilization device in the above-mentioned prior art utilizes a detector, a control unit, and two water pumps in combination with a roll stabilization water bag to achieve self-controlled roll stabilization of the water tank to maintain the stability of the hull, there are still certain shortcomings in the actual operation and use process. For example, the water bag is directly fixed on the support frame, which makes it inconvenient to quickly disassemble, replace and maintain the water bag. Utility Model Content

[0010] As a preferred technical solution, a first limiting groove is symmetrically opened on the inner side of the installation cavity, and the end of the pull plate is slidably connected to the inner side of the first limiting groove. Through the first limiting groove, the pull plate can be conveniently limited in the installation cavity.

[0011] As a preferred technical solution, a second slot is symmetrically provided on the inner wall of the first slot, and the end of the clamping rod away from the pull plate passes through the plug block and is plugged into the second slot.

At the same time, the clamping end of the clamping rod connected to the pull plate moves toward the first slot. When the clamping rod passes through the plug block and is plugged into the inner wall of the first slot, it can be fixed, so that the anti-rolling water bag can be quickly installed.

[0017] Second, when disassembling, no external tools are needed, and only the pull handles need to be pulled away from each other at the same time. The pull plate connected to the pull handle drives the clamping rod to separate from the plug in the first slot. At this time, the connecting shell on the anti-rolling water bag can be directly removed from the connecting seat, so that the anti-rolling water bag can be quickly disassembled, replaced and maintained.

DETAILED DESCRIPTION

[0023] refer to Figures 1 to 4The present embodiment describes an automatic anti-rolling device for a ship ballast tank, comprising a ship side 1 and an anti-rolling water bag 2. Support plates 3 are symmetrically fixedly installed on both sides of the ship side 1. A connecting shell 12 is fixedly connected to the outer side of the anti-rolling water bag 2. A through hole 13 is opened on the outer side of the connecting shell 12. A pipe joint of the anti-rolling water bag 2 passes through the through hole 13. A connecting mechanism 6 is symmetrically arranged on the upper end of the support plate 3. An insert block 16 is symmetrically fixedly installed on the outer side of the connecting shell 12. The support plate 3 is movably connected to the insert block 16 through the connecting mechanism 6. A detector, a control unit and a water pump are also arranged on the outer side of the ship side 1. The basic use principle of the automatic anti-rolling device is the same as that of the ship anti-rolling device disclosed in the publication number CN214296364U. The principle is: the rolling state of the ship can be detected by the detector, and the rolling state detection data is sent to the control unit. The control unit controls the first water pump in the first anti-rolling unit and the second water pump in the second anti-rolling unit based on the rolling state of the ship to play an anti-rolling role. If the ship tilts toward the first side wall, the control unit can control the first water pump to pump water in the first water bag into the second water tank based on the tilt direction, and control the second water pump to pump water in the first water tank into the second water bag, so as to pump water from the first side wall of the ship to the second side wall, and use the roll restoring moment generated by the moving water to offset the wave disturbance moment, thereby reducing the degree of shaking. The situation where the ship tilts toward the second side wall is similar to this, so as a prior art, it will not be described in detail here; the through hole 13 on the connecting shell 12 can facilitate the connecting pipe on the anti-rolling water bag 2 to pass through the connecting shell 12;

[0024] The connection mechanism 6 includes a connection seat 601, which is symmetrically fixedly installed on the upper end of the support plate 3. A mounting cavity 602 is provided on the inner side of the connection seat 601. A pull plate 606 is slidably connected to the inner side of the mounting cavity 602. A pull rod 605 is symmetrically fixedly connected to one side of the pull plate 606. A spring 603 is sleeved on the side of the pull rod 605 close to the pull plate 606. The end of the pull rod 605 away from the pull plate 606 slides through the cavity wall of the mounting cavity 602 and is fixedly installed with the same pull handle 604. A clamping rod 608 is symmetrically fixedly installed on one side of the pull plate 606 away from the pull rod 605, a first slot 607 is opened on the outer side of the connecting seat 601, and the end of the plug block 16 away from the connecting shell 12 is plugged into the first slot 607, and one end of the clamping rod 608 penetrates the plug block 16 and the inner wall of the first slot 607. When installing the anti-rolling water bag 2, first pull the handle 604 on the outer side of the connecting seat 601 at the same time, so that the handle 604 pulls the pull plate 606 in the installation cavity 6 through the pull rod 605. 02, and at the same time, the pull plate 606 compresses the spring 603 in the installation cavity 602, and at this time, the pull plate 606 drives the clamping rod 608 to retract into the installation cavity 602, and then the connecting shell 12 of the anti-rolling water bag 2 is inserted into the first slot 607 of the connecting seat 601 through the insert block 16. After insertion, the pull handle 604 is released, and under the reset effect of the spring 603, the pull plate 606 connected to the pull rod 605 slides in the installation cavity 602, and at the same time, the clamping rod 608 connected to the pull plate 606 is retracted into the installation cavity 602. The clamping end 8 moves toward the first slot 607, and when the clamping rod 608 penetrates the plug block 16 and is plugged into the inner wall of the first slot 607, it can be fixed. When disassembling, no external tools are needed, and only the pull handles 604 need to be pulled away from each other at the same time. The pull handles 604 drive the clamping rod 608 to separate from the plug block 16 in the first slot 607 through the pull plate 606 connected to the pull rod 605. At this time, the connecting shell 12 on the anti-rolling water bag 2 can be directly removed from the connecting seat 601.

[0025] refer to Figure 2 The upper end of the connecting seat 601 is fixedly connected with a first fixing plate 10, and the lower end of the connecting seat 601 is symmetrically fixedly connected with a second fixing plate 11.

The pull plate 606 is slidably connected to the first limiting groove 7 in the installation cavity 602, so that the pull plate 606 can be conveniently limited in the installation cavity 602. When disassembling, when the limiting plate is pulled to the other end of the first limiting groove 7, the clamping rod 608 just disengages from the first slot 607, so that the plug block 16 of the connecting shell 12 can be quickly disassembled and assembled.

[0027] refer to Figure 3 The inner wall of the first slot 607 is symmetrically provided with a second slot 14, and the end of the clamping rod 608 away from the pull plate 606 passes through the plug block 16 and is plugged into the second slot 14. By using the second slot 14 on the first slot 607, the clamping rod 608 can be conveniently passed through the plug block 16 and plugged into the inner wall of the first slot 607, thereby ensuring the stability of the plug block 16 being clamped and fixed in the first slot 607.

[0028] refer to Figure 4 A circular hole 15 is symmetrically opened on the inner side of the plug block 16, and one end of the clamping rod 608 slides through the circular hole 15. By using the circular hole 15 on the plug block 16, the clamping rod 608 can easily pass through the plug block 16.

The elastic rope 4 on the support plate 3, combined with the hook at one end of the elastic rope 4, can be conveniently hung with the hanging block 5 on the ship's side 1, thereby further ensuring the stability of the anti-rolling water bag 2.

[0031] Principle and advantages of use: During use, when fixing the anti-rolling water bag 2, first pull the handle 604 on the outside of the connecting seat 601 at the same time, so that the handle 604 pulls the pull plate 606 to slide in the installation cavity 602 through the pull rod 605, and at the same time, the pull plate 606 compresses the spring 603 in the installation cavity 602, and at this time, the pull plate 606 drives the clamping rod 608 to retract into the installation cavity 602, and then the connecting shell 12 of the anti-rolling water bag 2 is inserted into the first slot of the connecting seat 601 through the insert block 16. 607, after insertion, release the pull handle 604, and under the reset effect of the spring 603, the pull plate 606 connected to the pull rod 605 slides in the installation cavity 602, and at the same time, the clamping end of the clamping rod 608 connected to the pull plate 606 moves toward the first slot 607, and when the clamping rod 608 passes through the plug block 16 and is plugged into the inner wall of the first slot 607, it can be fixed, and finally, the elastic rope 4 on the support plate 3 is used, combined with the hook at one end of the elastic rope 4, to be hung and fixed with the hanging block 5 on the side of the ship 1;

[0032] When disassembling, no external tools are needed. One only needs to pull the handles 604 away from each other at the same time. The pull plate 606 connected to the handles 604 through the pull rod 605 drives the clamping rod 608 to separate from the plug block 16 in the first slot 607. At this time, the connecting shell 12 on the anti-rolling water bag 2 can be directly removed from the connecting seat 601.
