Description

Technical Field

[0001] This invention relates to the field of ship ballast water discharge technology, specifically a ship ballast water treatment and discharge device. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation capable of navigating or anchoring on water for transport or operations. Depending on different usage requirements, they possess different technical specifications, equipment, and structural forms. A ship is a man-made means of transportation primarily operating in geographical waters. Furthermore, civilian ships are generally called boats, military ships are called warships, and small boats are called boats or dinghies; collectively, they are referred to as ships or vessels. Internally, they mainly include interior space, supporting structures, and drainage structures, and possess a propulsion system that utilizes external or internal energy sources.

[0003] Ballast water refers to the water and suspended matter added to a ship to control its list, trim, draft, stability, or stress. When a ship is loaded with cargo, ballast water can also be used to ballast and regulate the load between ballast tanks, determining a specific draft difference or equal draft to ensure smooth and safe navigation in specific waters.

[0004] When repairing a ship, ballast water needs to be discharged. Ballast water contains certain pollutants, and if it is discharged directly, it is easy to cause re-contamination. Therefore, it needs to be treated before discharge. Currently, when treating ballast water, the discharge device needs to be moved to the discharge outlet. Since the height of the ship's discharge outlet is relatively different and it is difficult to fit it to the discharge outlet, leakage is likely to occur during discharge. Summary of the Invention

[0005] The purpose of this invention is to provide a ship ballast water treatment and discharge device to solve the problems existing in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ship ballast water treatment and discharge device, comprising a base, and further comprising:

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-7 A ballast water treatment and discharge device for ships includes a base 1. A support plate 2 is fixedly connected to the top of the base 1 via a support column. A drainage hopper 3 is fixedly connected to the top of the support plate 2 via a fixing rod. A connecting pipe 5 is connected to the top of the drainage hopper 3. A sealing gasket 4 is provided at the top end of the connecting pipe 5. A filter screen 6 for filtering ballast water is provided inside the drainage hopper 3. A fixing plate 8 is fixedly connected above the filter screen 6 and to the inner wall of the drainage hopper 3. A rotating rod 9 is rotatably connected inside the fixing plate 8. A cleaning plate 11 for cleaning the filter screen 6 is fixed at the bottom end of the rotating rod 9. The bottom of the drainage hopper 3 is connected to... The drain pipe 7 is provided. The inside of the drain hopper 3 is equipped with a transmission structure 10 for driving the rotating rod 9 to rotate. The left and right sides of the support plate 2 are respectively movably connected to the folded plate 15 and the movable plate 14. The top of the folded plate 15 is fixedly connected to the arc plate 20. The two ends of the arc plate 20 are fixed with push plates 13. The other end of the push plate 13 is fixed to the sealing gasket 4. The bottom end of the movable plate 14 extends into the interior of the base 1 and is fixed with a pressure plate 19. The bottom of the pressure plate 19 is provided with a pressing structure 18. The bottom of the support plate 2 is provided with a drive structure 16 for driving the movable plate 14 and the folded plate 15 to move.

[0034] The transmission structure 10 includes a straight rod 101, a force-applying plate 102, a driving wheel 103, a driven wheel 104, a movable rod 105, a first bevel gear 106, and a second bevel gear 107. The straight rod 101 is rotatably connected inside the drainage hopper 3. There are several force-applying plates 102, all of which are fixed around the surface of the straight rod 101. The driving wheel 103 is fixed to one end of the straight rod 101 and is connected to the driven wheel 104 via a belt. One side of the driven wheel 104 is fixed to one end of the movable rod 105, and the other end of the movable rod 105 extends to the drainage hopper 3. The bucket 3 is fixed inside and to one side of the first bevel gear 106. The other side of the first bevel gear 106 meshes with the second bevel gear 107. The bottom of the second bevel gear 107 is fixed to the top of the rotating rod 9. Thus, during the discharge of ballast water, the downward force of the water flow can drive the force plate 102, the straight rod 101 and the drive wheel 103 to rotate. At the same time, the driven wheel 104 is driven to rotate through the belt, which in turn drives the movable rod 105 and the first bevel gear 106 to rotate, thereby driving the second bevel gear 107 and the rotating rod 9 to rotate.

[0035] The drive structure 16 includes a motor 161, a gear 162, and teeth 163. The motor 161 is fixed to the bottom of the support plate 2. The output shaft of the motor 161 is fixed to one side of the gear 162. There are several teeth 163, which are fixed at equal intervals on the opposite sides of the movable plate 14 and the folding plate 15. The gear 162 meshes with the movable plate 14 and the folding plate 15 through the teeth 163. Thus, when the sealing gasket 4 and the pressure plate 19 are moved, the motor 161 can be started, which drives the gear 162 to rotate. At the same time, the teeth 163 drive the folding plate 15 to move upward, while the movable plate 14 moves downward.

[0036] The clamping structure 18 includes a limiting rod 181, a stop plate 182, and a spring 183. There are several limiting rods 181, and they are all movably connected to the front and rear sides of the pressure plate 19. The stop plate 182 is fixed to the bottom end of the pressure plate 19. The spring 183 is sleeved on the surface of the limiting rod 181. The two ends of the spring 183 are fixed to the pressure plate 19 and the stop plate 182 respectively. As the pressure plate 19 moves, it can drive the stop plate 182 to move together. When the stop plate 182 contacts the ground, if the sealing gasket 4 has not yet contacted the ship's drain outlet, it can continue to drive the sealing gasket 4 to move, so that the sealing gasket 4 is tightly fitted to the ship's drain outlet.

[0037] The force-applying plate 102 is arc-shaped, and the surface of the force-applying plate 102 has grooves, so that the water flow can apply force to the force-applying plate 102, making it easier to drive the force-applying plate 102 to rotate in one direction.

[0038] Slide plates 17 are fixedly connected to the opposite sides of movable plate 14 and folded plate 15. The surface of slide plates 17 is movably connected to the inside of support plate 2, so as to provide auxiliary support for movable plate 14 and folded plate 15 and maintain their stability when they move inside support plate 2.

[0039] The connecting pipe 5 is a flexible hose, and its extension length is the same as the movement distance of the folded plate 15. This will not affect the contact between the sealing gasket 4 and the ballast water drainage port of the ship, thereby improving the sealing performance when in contact with the ship.

[0040] The cleaning plate 11 is inclined, and the angle of inclination is close to the top surface of the filter screen 6. This allows the cleaning plate 11 to better clean the impurities on the surface of the filter screen 6 when it rotates, so as to facilitate subsequent filtration.

[0041] The left side of the drainage hopper 3 is connected to the discharge port 12, which is inclined downwards, so that the cleaned impurities can flow out from the discharge port 12, thus facilitating the unified treatment of the outflowing impurities.

[0042] The bottom of the base 1 is provided with a placement groove, and the abutment plate 182 and the pressure plate 19 are both located inside the placement groove, so that the movement of the base 1 will not be affected when it is not in use.

[0043] Working principle: In use, first move the device to the ballast water outlet of the ship, then start the motor 161, which drives the gear 162 to rotate. Simultaneously, the gear 163 drives the folding plate 15 and the movable plate 14 to move. The folding plate 15 moves upward, causing the arc-shaped plate 20 and the push plate 13 to move, bringing the sealing gasket 4 into contact with the ballast water outlet of the ship. Meanwhile, the movable plate 14 moves downward, causing the pressure plate 19 to move downward, bringing the bottom abutment 182 of the pressure plate 19 into contact with the ground, thereby improving the device's performance during ballast water discharge. After the ballast water enters the interior of the drainage hopper 3, it can be filtered through the filter screen 6 and discharged through the drain pipe 7. After a long period of filtration, the surface of the filter screen 6 will be adsorbed with a large number of impurity particles. In order to improve the filtration effect, as the ballast water continues to be discharged, the transmission structure 10 will drive the rotating rod 9 to rotate, and at the same time drive the cleaning plate 11 to rotate, so that the cleaning plate 11 cleans the surface of the filter screen 6. The cleaned impurities will be discharged through the discharge port 12.
