[0002] During the voyage of a ship, whether it is sailing in the sea or moored in a port, it will inevitably be infiltrated or accumulated by water. The water may come from rainwater, seawater infiltration, domestic sewage, etc. If it is not discharged in time, the accumulated water will continue to accumulate, thereby increasing the weight of the ship itself and affecting the buoyancy and stability of the ship. Excessive accumulated water may also cause corrosion and damage to the hull structure, thereby affecting the safety and service life of the ship, and the hull needs to be drained. When draining the hull, drainage equipment needs to be used.

[0003] Existing drainage equipment uses vacuum pumps to drain water, and drainage equipment is crucial to the maneuverability and navigation safety of ships. When a ship encounters bad weather or an emergency, such as strong winds and waves, seawater backflow, etc., the drainage system can quickly and effectively remove the water in the ship, help the ship maintain stability, and avoid capsizing or other accidents.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0019] See also Figures 1 to 8 The present invention provides a technical solution: a drainage system for a ship, comprising: a hull 1, a water inlet 2 and a water outlet 3, wherein the water inlet 2 and the water outlet 3 are arranged on both sides of the hull 1, when the ship needs to be weighted and stabilized during navigation, the water inlet 2 discharges water into the ship to increase the weight of the hull 1, when the ship needs to reduce weight during navigation, the water outlet 3 discharges water from the ship, a water storage tank 4 is connected to the hull 1, and the water storage tank 4 is used to store rainwater, waste water, etc. in the hull 1, when the hull 1 is too heavy, the accumulated water in the water storage tank 4 needs to be discharged through the water outlet 3, when the hull 1 is too light and the hull 1 shakes, the water is discharged into the water storage tank 4 through the water inlet 2, so that the hull 1 can travel safely during navigation; Also includes: The monitoring component 5 is arranged in the hull 1. The monitoring component 5 is used to monitor the amount of water accumulated in the ship. By monitoring the water level in the ship by the monitoring component 5, the water intake and discharge of the ship are controlled, and then the amount of water discharged into the ship and the amount of water discharged out of the ship are controlled, so that the hull 1 can travel stably during the navigation process, thereby ensuring the safety of the crew on board; The locking assembly 7 is connected to the monitoring assembly 5. The locking assembly 7 is used to fix the position of the monitoring assembly 5. The locking assembly 7 can fix the monitoring assembly 5, thereby ensuring the stability of the monitoring assembly 5 and preventing the monitoring assembly 5 from making errors during the monitoring process; Drainage component 6, the drainage component 6 is connected to the water storage tank 4, and the drainage component 6 is connected to the water inlet 2 and the water outlet 3. The drainage component 6 can discharge the accumulated water in the ship and inject water into the ship. The drainage component 6 is convenient for draining water into the water storage tank 4 and draining water out of the water storage tank 4, controlling the water storage amount in the water storage tank 4, and then adjusting the weight of the hull 1 to ensure the safety of the navigation of the hull 1.

[0020] The monitoring component 5 includes a fixing frame 51, which is fixedly connected to the top of the water storage tank 4. A water level sensor 52 is provided on the fixing frame 51. An offset sensor 53 is connected between the fixing frame 51 and the water level sensor 52. By setting the fixing parts, the water level sensor 52 and the offset sensor 53 can be fixed and protected, thereby extending the service life of the water level sensor 52 and the offset sensor 53. The water level in the water storage tank 4 can be monitored by the water level sensor 52, and whether the hull 1 is shaking greatly can be monitored by the offset sensor 53. Then, according to the monitoring of the water level and the monitoring of the shaking of the hull 1, the water storage tank 4 can be drained inward or outward.

[0021] The water level sensing component 52 includes a floating plate 521, which is arranged in the water storage tank 4. Two connecting ropes 522 are connected to the top of the floating plate 521. The floating plate 521 is connected to a distance sensor 8, and the fixed frame 51 is connected to a receiver 9. The distance sensor 8 and the receiver 9 are used together to detect the distance between the floating plate 521 and the fixed frame 51. By setting the floating plate 521, the floating plate 521 can move according to the water level in the water storage tank 4, and the connecting rope 522 fixes the floating plate 521. By setting the distance sensor 8 and the receiver 9, the water level in the water storage tank 4 can be monitored, and then quantitative drainage can be performed according to the water level in the water storage tank 4.

[0022] Both connecting ropes 522 are connected with a retractable component 55, and the two connecting ropes 522 are respectively wound around the retractable component 55. The two retractable components 55 can retract and release the connecting ropes 522 according to the water level in the water storage tank 4 to adjust the position of the floating plate 521. When the water level in the water storage tank 4 drops, the connecting ropes 522 are extended according to the water level. When the water level in the water storage tank 4 rises, the retractable component 55 can store the connecting ropes 522, thereby facilitating the connection ropes 522 to be adjusted according to the water level in the water storage tank 4.

[0023] The retractable member 55 includes a connecting plate 523, which is connected to the offset sensing member 53. A motor 551 is fixedly mounted on the connecting plate 523.

A retractable reel 552 is fixedly connected to the rotating shaft 553, and the connecting rope 522 is wound around the retractable reel 552. When the water level in the water storage tank 4 drops, the floating plate 521 drops, and then the floating plate 521 drives the connecting The rope 522 rotates on the reel 552 to extend the length of the connecting rope 522. When the water level in the water storage tank 4 rises, the float 521 rises, and the motor 551 starts. The motor 551 drives the rotating shaft 553 to rotate, and the rotating shaft 553 drives the reel 552 to rotate, thereby reeling the connecting rope 522, thereby preventing the connecting rope 522 from accumulating on the float 521 and getting entangled, ensuring that the connecting rope 522 can be used normally and extending the service life of the connecting rope 522.

[0024] Limit plates 554 are provided at both ends of the reel 552, and the limit plates 554 are rotatably connected to the rotating shaft 553. A telescopic shaft 54 ​​is connected between the floating plate 521 and the fixed frame 51. By setting the limit plates 554, the connecting rope 522 is prevented from falling off the reel 552 when the connecting rope 522 is retracted. By setting the telescopic shaft 54, the position of the floating plate 521 is limited when the water level drops, preventing the floating plate 521 from shaking greatly with the hull 1, which would cause inaccurate monitoring results.

[0025] The offset sensing component 53 includes two tension sensors 531, and the two tension sensors 531 are fixedly mounted on the fixing frame 51, and the two tension sensors 531 are respectively connected to the two connecting plates 523, and the two tension sensors 531 are used to monitor the tension of the two connecting ropes 522. When the hull 1 shakes, the connecting ropes 522 deviate with the shaking of the hull 1, and then the two tension sensors 531 respectively monitor the tension of the two connecting ropes 522. The difference between the two tension sensors 531 is within the normal range of "0~20". When the difference between the two tension sensors 531 exceeds "20", it is detected that the hull 1 is shaking seriously, and it is necessary to drain water into the water storage tank 4 through the water inlet 2 to ensure the stability of the hull 1.

[0026] The locking assembly 7 includes two electric telescopic rods 71, which are respectively fixedly mounted on two connecting plates 523. One end of the electric telescopic rod 71 is fixedly connected with a clamping piece. The electric telescopic rod 71 drives the clamping piece to move laterally, thereby fixing the rotating shaft 553. After the connecting rope 522 is wound up, the rotating shaft 553 is fixed to ensure the stability of the position of the connecting rope 522.

[0027] The clamping part includes a blocking plate 73, which is connected to the connecting plate 523. A stop plate 72 is connected to the electric telescopic rod 71. The stop plate 72 and the blocking plate 73 are used together to fix the rotating shaft 553. The electric telescopic rod 71 drives the stop plate 72 to move horizontally. The rotating shaft 553 can be fixed by using the stop plate 72 and the blocking plate 73 together. Embodiment 2

[0028] The drainage assembly 6 includes an inlet pipe 62 and a drain pipe 61. The inlet pipe 62 is connected to the top of one side of the water storage tank 4, and the drain pipe 61 is connected to the bottom of one side of the water storage pipe. The water inlet 2 is connected to a branch pipe 1 63, and the branch pipe 1 63 is connected to the water inlet pipe 62. A venturi ejector 65 is connected between the branch pipe 1 63 and the water inlet pipe 62. The water outlet 3 is connected to a branch pipe 2 64, and the branch pipe 2 64 is connected to the drain pipe 61. A venturi ejector 65 is connected between the branch pipe 2 64 and the drain pipe 61. The water inlet pipe 62 cooperates with the branch pipe 1 63 to work. The high-pressure water flow provided by the first 63 passes through the Venturi ejector 65 to form a negative pressure inside it, which is convenient for draining water into the water storage tank 4, thereby increasing the weight of the hull 1 and slowing down the shaking of the hull 1. The drain pipe 61 is used in conjunction with the branch pipe 2 64. When working, the high-pressure water flow provided by the drain pipe 61 passes through the Venturi ejector 65 to form a negative pressure inside it, which is convenient for draining water out of the water storage tank 4, thereby reducing the weight of the hull 1, preventing the hull 1 from being too heavy, and ensuring the normal driving of the hull 1. The drain pipe 61 is arranged at the bottom of the water storage tank 4 to reduce the discharge of oil and dirt in the accumulated water, thereby protecting the environment.
