Description

Technical Field

[0001] The present invention belongs to the technical field of ship equipment, and particularly relates to an anti-wave and anti-rolling water tank. Background Art

[0002] When a ship sails on the sea, it will inevitably encounter waves and winds. The ship's rocking caused by waves and winds not only affects the navigation safety of the ship, reduces the stability of cargo transportation, but also brings great inconvenience to the lives and work of the crew. In severe cases, it may even cause health problems such as seasickness. When the existing anti-rolling water tanks cope with complex wave and wind conditions, the anti-rolling effect is often unsatisfactory and difficult to meet the requirements of the ship's stability under severe sea conditions. For example, when the traditional U-shaped anti-rolling water tank encounters waves and winds with different frequencies and amplitudes, the response of the water body in the water tank is not flexible enough to effectively offset the rocking moment of the ship in a timely manner, resulting in a still large rocking amplitude of the ship. At the same time, the water body in the water tank is prone to breed microorganisms after long-term use, causing pipeline blockage and equipment corrosion, affecting the normal operation of the water tank. Therefore, it is of great practical significance to develop a water tank that can significantly improve the ship's anti-wave and anti-rolling effects and has good maintenance performance. For this reason, an anti-wave and anti-rolling water tank is improved and designed. Summary of the Invention

[0003] In view of the above deficiencies existing in the prior art, the present invention provides an anti-wave and anti-rolling water tank to solve the problems in the above background art.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: An anti-wave and anti-rolling water tank includes a main water tank, a connecting water tank, a water inlet and outlet system, an adjusting partition board, and a control system; wherein, the main water tanks are symmetrically arranged on the left and right sides at the bottom of the ship and are interconnected through the connecting water tank to form a basic structure with interconnected water bodies; The water inlet pipe and the drain pipe of the water inlet and outlet system are respectively connected to the main water tank and the seawater environment outside the ship by means of flange plates. The water pump is installed on the water inlet pipe or the drain pipe, and the flow regulating valve and the check valve are also installed on the water inlet pipe and the drain pipe to control the inflow and outflow and the flow direction of the water body in the water tank; The adjusting partition board is installed in the main water tank and the connecting water tank and is an adjustable structure. The sensors of the control system are installed on the ship to monitor the rocking state of the ship and transmit the signals to the controller. After analyzing and processing the signals transmitted by the sensors, the controller issues instructions to the actuator, and the actuator further controls the start and stop of the water pump, the opening degree of the flow regulating valve, and the action of the adjusting partition board.

[0005] Further, the adjusting partition board is composed of a partition board body, an adjusting shaft, and a driving device. The partition board body is connected to the water tank wall through the adjusting shaft, and the driving device is connected to the adjusting shaft. By means of the action of the driving device, the control of the angle and position of the partition board body is realized.

[0006] Further, the sensor includes multiple types of sensors for collecting data on the rocking angle, frequency, and acceleration of the ship, providing a basis for the regulation of the water tank system, specifically including a gyroscope sensor, an acceleration sensor, and a rate gyroscope.

[0007] Further, the controller analyzes and processes the signals transmitted by the sensors according to a preset control algorithm, calculates the inflow and drainage volume, and the angles and positions of the regulating partitions, and issues control instructions to the actuator accordingly.

[0008] Further, the actuator is a key execution unit of the control system, responsible for receiving the instructions issued by the controller, and mainly includes the following parts: a water pump drive assembly connected to the water pump, and a flow control valve control device connected to the flow control valve.

[0009] Further, the control system also includes a data storage module, which is connected to the sensors and the controller, and is used to store the sensor acquisition data, the calculation results of the controller, and the operation parameters of the water tank during the ship's navigation.

[0010] Further, it also includes a buffer airbag, which is arranged at the top of the main water tank and the connecting water tank, and is used to buffer the impact of the water body and regulate the air pressure in the water tank.

[0011] Further, it also includes a water quality purification module, which is composed of a filter and an ultraviolet sterilizer. The filter and the ultraviolet sterilizer are sequentially installed on the water inlet pipe and the drain pipe. The filter is used to filter impurities and microorganisms in the seawater, and the ultraviolet sterilizer is used to kill bacteria and viruses in the water.

[0012] Further, it also includes an anti-biofouling device installed on the inner walls of the main water tank, the connecting water tank, the water inlet pipe, and the drain pipe to prevent the attachment and growth of marine organisms. The anti-biofouling device is composed of an electrode and a power supply. The electrodes are evenly installed on the inner walls of the main water tank, the connecting water tank, the water inlet pipe, and the drain pipe, and the power supply is connected to the electrodes to provide a direct current for the electrodes, causing an electrolytic reaction in the water body around the electrodes to prevent the attachment and growth of marine organisms.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By optimizing the water tank structure, setting multiple regulating partitions and buffer airbags, changing the flow characteristics of the water body in the water tank, and cooperating with an intelligent water inlet and drainage system and a control system, the water tank can respond more effectively to the rocking of the ship, significantly reducing the rocking amplitude of the ship. The adjustable structure of the regulating partition, the intelligent control system, and the precisely adjustable water inlet and drainage system enable the water tank to automatically adjust parameters according to different wind and wave conditions and adapt to various complex sea conditions. Whether it is high-frequency small-amplitude wind and waves or low-frequency large-amplitude wind and waves, the water tank of the present invention can achieve good anti-rolling effects. Effectively reduce the rolling of the ship, reduce the risk of the ship capsizing in wind and waves, and ensure the navigation safety of the ship. At the same time, reducing the rolling of the ship is also beneficial to improving the stability of cargo transportation and reducing the possibility of cargo damage. Reduce the rolling amplitude of the ship, reduce the occurrence of discomfort symptoms such as seasickness among crew members, improve the comfort of crew members during navigation, and is beneficial to the physical and mental health and work efficiency of crew members. Through the action of the water quality purification module and the anti-biological adhesion device, it can effectively prevent the growth of microorganisms and the attachment of marine organisms in the water tank, reduce pipeline blockage and equipment corrosion, reduce the maintenance cost of the water tank, and extend the service life of the water tank.

[0019] As Figures 1-4 shown, the present invention. Specifically, an anti-wave and anti-rolling water tank includes a main water tank 1, a connecting water tank 2, a water inlet and drainage system 3, a regulating partition 4, and a control system 5; among them, the main water tanks 1 are symmetrically arranged on the left and right sides of the bottom of the ship and are interconnected through the connecting water tank 2 to form a basic structure with interconnected water bodies. The water inlet pipe 31 and the drain pipe 32 of the water inlet and drainage system 3 are respectively connected to the main water tank 1 and the seawater environment outside the ship by means of flange plates. The water pump 33 is installed on the water inlet pipe 31 or the drain pipe 32, and the flow regulating valve 34 and the check valve 35 are also installed on the water inlet pipe 31 and the drain pipe 32 to control the inflow and outflow of water in the water tank and the flow direction. The adjustable partition plate 4 is installed in the main water tank 1 and the connecting water tank 2 and is of an adjustable structure. The sensor 51 of the control system 5 is installed on the ship to monitor the rocking state of the ship and transmit signals to the controller 52. After analyzing and processing the signals transmitted by the sensor 51, the controller 52 issues instructions to the actuator 53, and the actuator 53 further controls the start and stop of the water pump 33, the opening of the flow regulating valve 34, and the movement of the adjustable partition plate 4.

[0020] Further, the adjustable partition plate 4 is composed of a partition plate body 41, an adjustment shaft 42, and a driving device 43. The partition plate body 41 is connected to the water tank wall through the adjustment shaft 42, and the driving device 43 is connected to the adjustment shaft 42. By means of the action of the driving device 43, the control of the angle and position of the partition plate body 41 is realized.

[0021] Further, the sensor 51 includes various types of sensors for collecting data on the rocking angle, frequency, and acceleration of the ship, providing a basis for the regulation of the water tank system, specifically including a gyroscope sensor, an acceleration sensor, and a rate gyroscope.

[0022] Further, the controller 52 analyzes and processes the signals transmitted by the sensor 51 according to a preset control algorithm, calculates the inflow and outflow volume, the angle and position of the adjustable partition plate 4, and issues control instructions to the actuator 53 accordingly.

[0023] Further, the actuator 53 is a key execution unit of the control system 5, responsible for receiving the instructions issued by the controller 52, and mainly includes the following parts: a water pump driving component connected to the water pump 33, and a flow regulating valve control device connected to the flow regulating valve 34.

[0024] Further, the control system 5 also includes a data storage module 54, which is connected to the sensor 51 and the controller 52, and is used to store the sensor acquisition data, the controller operation results, and the water tank operation parameters during the ship's navigation.

[0025] Further, a buffer airbag 6 is also included. The buffer airbag 6 is arranged at the top of the main water tank 1 and the connecting water tank 2 for buffering the water impact and regulating the air pressure in the water tank.

[0026] Further, a water quality purification module 7 is also included. The water quality purification module 7 is composed of a filter 71 and an ultraviolet sterilizer 72. The filter 71 and the ultraviolet sterilizer 72 are sequentially installed on the water inlet pipe 31 and the water discharge pipe 32. The filter 71 is used to filter impurities and microorganisms in seawater, and the ultraviolet sterilizer 72 is used to kill bacteria and viruses in the water.

[0027] Further, it further includes an anti-biological fouling device 8 installed on the inner walls of the main water tank 1, the connecting water tank 2, the water inlet pipe 31 and the drain pipe 32 to prevent the attachment and growth of marine organisms. The anti-biological fouling device 8 is composed of an electrode 81 and a power supply 82. The electrode 81 is uniformly installed on the inner walls of the main water tank 1, the connecting water tank 2, the water inlet pipe 31 and the drain pipe 32. The power supply 82 is connected to the electrode 81 to provide a direct current to the electrode 81, causing an electrolysis reaction in the water body around the electrode 81 to prevent the attachment and growth of marine organisms.

[0028] The principle is as follows: The water inlet and outlet system 3, as the core component for changing the water volume and center of gravity in the water tank, is composed of a water inlet pipe 31, a drain pipe 32, a water pump 33, a flow regulating valve 34, and a check valve 35. When the ship sways in the wind and waves, the control system 5 accurately controls the start and stop of the water pump 33 and the opening degree of the flow regulating valve 34 according to the ship's sway state feedback by the sensor 51, sucks seawater through the water inlet pipe 31 or discharges seawater through the drain pipe 32, precisely adjusts the water volume in the water tank, changes the position of the ship's center of gravity, and thus effectively offsets the swaying moment of the ship and inhibits the swaying trend of the ship. Adjusting partition plates optimize water body flow: The adjusting partition plates 4 are arranged in the main water tank 1 and the connecting water tank 2, and it consists of a partition plate body 41, an adjusting shaft 42, and a driving device 43. Under different wind and wave conditions, the control system 5 sends instructions to the driving device 43 to adjust the angle and position of the partition plate body 41 through the adjusting shaft 42. When encountering high-frequency and small-amplitude wind and waves, the partition plate body 41 is adjusted to a smaller angle to reduce the damping of the water body in the water tank, enabling the water body to quickly respond to the ship's sway; while in the face of low-frequency and large-amplitude wind and waves, the partition plate body 41 is adjusted to a larger angle to increase the damping of the water body and enhance the inhibitory effect on the ship's sway. By changing the flow path and damping characteristics of the water body, the anti-sway effect is improved. Buffer airbags buffer water body impact: The buffer airbags 6 are arranged at the tops of the main water tank 1 and the connecting water tank 2 and are made of flexible high-strength rubber. When the ship sways, the water body in the water tank fluctuates up and down and impacts the buffer airbags 6. The airbags absorb the impact energy of the water body through their own deformation, reduce the impact force of the water body on the water tank wall, and thus reduce the swaying amplitude of the ship. In addition, the buffer airbags 6 can also adjust the air pressure in the water tank, optimize the flow state of the water body in the water tank, and further enhance the anti-sway effect. The intelligent control system provides precise regulation, real-time monitoring and analysis: The sensors 51 are installed at key positions such as the center of gravity of the ship's hull, the bow, and the stern of the ship, and can real-time monitor parameters such as the swaying angle, swaying frequency, and acceleration of the ship, and transmit these data to the controller 52 through a data cable. The controller 52 uses a high-performance industrial computer with preset control algorithms built-in, and can quickly analyze and process the signals transmitted by the sensors 51, calculate the parameters required for adjusting the water tank, such as the water inflow and outflow volume, the angle and position of the adjusting partition plate 4, etc. Instruction execution and coordination: The actuator 53 controls the start and stop of the water pump 33, the opening degree of the flow regulating valve 34, and the action of the adjusting partition plate 4 according to the instructions issued by the controller 52, realizing the intelligent control of the water tank. At the same time, the water quality purification module 7 filters and sterilizes the seawater during the water inlet and outlet process to prevent impurities and microorganisms from entering the water tank; the anti-biofouling device 8 prevents marine organisms from attaching and growing on the inner walls of the water tank and pipelines through electrolytic reactions, ensuring the stable operation of the water tank system. The data storage module 54 records various data during the ship's navigation, provides a basis for subsequent data analysis and system optimization, and the remote communication module 55 realizes real-time communication between the water tank and the onshore monitoring center, facilitating the staff to remotely monitor the operation status of the water tank.
