[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] As described in the background technology, in order to meet the needs of the ship during the driving process, liquid storage tanks such as oil tanks and water tanks are generally provided in the ship for storing fuel, cooling, supplying personnel on board, etc. However, during the driving process of the ship, the fluid in the liquid storage tank will fluctuate, which will not only affect the normal operation of the ship, but also have an adverse effect on the comfort of the passengers. When the hull is impacted by waves, the fluid in the liquid storage tank will produce obvious fluctuations, thereby causing noise and vibration problems. Secondly, the fluctuation of the fluid in the liquid storage tank will not only cause discomfort to the passengers, but also lead to energy waste. When the fluid fluctuates, the kinetic energy therein will be converted into mechanical energy, generating noise and vibration, and at the same time, it will consume a certain amount of energy, resulting in energy waste. At present, in order to avoid the violent fluctuation of the fluid in the liquid storage tank, a wave-breaking board is generally provided in the liquid storage tank to reduce the fluctuation and impact of the liquid inside the liquid storage tank and improve the stability of the ship's driving. However, although the wave-breaking board reduces the fluctuation of the fluid inside the liquid storage tank, there is still energy waste.

[0047] In order to improve the above problems, in one aspect of the present application, a liquid storage tank is proposed, referring to Figure 1 and Figure 2 , which mainly includes: a box body 1, a swinging member 2, a follower assembly, a first output shaft 4, a rotating assembly 5 and a second output shaft 6, wherein the box body 1 is used to contain fluid; the swinging member 2 is arranged in the box body 1, and is used to capture the kinetic energy of the fluid, thereby reducing the fluctuation degree of the fluid in the box body 1; the follower assembly is used to transfer the kinetic energy of the fluid captured by the swinging member 2 to the first output shaft 4; the first output shaft 4 is used to perform the final energy conversion, thereby improving the energy utilization rate; the rotating assembly 5 is used to further capture the kinetic energy of the fluid and further reduce the fluctuation degree of the fluid in the box body 1; the second output shaft 6 is also used to perform the final energy conversion, thereby improving the energy utilization rate.

[0048] Specifically, different fluids and media can be stored in the box 1, that is, the box 1 mentioned in this application can be a transport water tank, a transport oil tank, an electrolyte storage tank or a reaction tank of a flow battery, etc. Further, the box 1 can be an ammonia storage tank or other acidic solution storage tank, etc. Considering that the acidity and alkalinity of the solution may corrode the components in the box 1, in specific applications, the components in the box 1 should be made of corrosion-resistant materials. On the other hand, the box can also be a buoyancy tank, an oil tank installed on a ship, a fresh water tank, a ballast water tank, a roll reduction tank or a flow battery electrolyte storage tank, as long as it is a cavity filled with a flowing medium, which does not affect the protection scope of this application.

[0049] Specifically, in the exemplary embodiment, the housing 1 is made of 304 stainless steel, which ensures that it has excellent corrosion resistance and high temperature resistance, effectively protects the fluid medium in the housing 1 from the influence of the external environment, and prolongs the service life of the housing 1.

[0050] Furthermore, in the exemplary embodiment, the box body 1 adopts a rectangular structure and has a solid frame and side panels. A cavity for accommodating the fluid is formed inside the box body 1 to ensure that the fluid can flow freely therein.

[0051] Furthermore, in some embodiments, the size and volume of the tank 1 are designed according to specific application requirements. The size should be adapted to the installation space of the steamer, and the volume should meet the requirements for storing fluid, while taking into account factors such as weight and balance.

[0052] Furthermore, in some embodiments, the box 1 is provided with inlet and outlet ports for connecting fluid pipelines and other system components. These ports are usually located on one side or the top of the box 1 to facilitate the delivery of fluid.

[0053] Furthermore, in some embodiments, the housing 1 has good sealing performance to prevent fluid leakage and intrusion of external pollutants. The sealing is achieved by sealing gaskets, O-rings and fasteners to ensure the safety and cleanliness of the fluid inside the housing 1.

[0054] Furthermore, in some embodiments, in order to increase the rigidity and stability of the box 1, a reinforcement structure such as a longitudinal beam and a cross beam may be provided inside the box 1. These structures can disperse and absorb the pressure and impact generated by the fluid, thereby improving the vibration resistance and durability of the box 1.

[0055] Furthermore, in some embodiments, in order to improve the corrosion resistance and aesthetics of the box body 1, the box body 1 may be subjected to surface treatment, such as spraying anti-corrosion paint or electroplating, etc. This can prevent the box body 1 from being oxidized, corroded, and eroded by the external environment.

[0056] Specifically, in the exemplary embodiment, the first output shaft 4 is sealed and penetrates the housing 1 , and is connected to the swing member 2 , and the swing member 2 can drive the first output shaft 4 to rotate.

[0057] Specifically, the swinging member 2 can have various forms to capture the kinetic energy of the fluid in different ways. For example, it can be in the form of an impeller or in the form of a plate.

[0058] Specifically, in some embodiments, referring to Figure 3 and Figure 4 The swing member 2 is in the form of an impeller, which is composed of a plurality of blades. Each blade is in an arc or fan shape and is fixed to the central axis of the swing member 2. The material selection of the impeller should have good corrosion resistance and mechanical strength to ensure its long-term stable operation in the housing 1. Further, the shape and curvature of the blades are precisely designed to ensure that the kinetic energy can be absorbed and reduced to the greatest extent when the oil fluctuates and provide a smooth swinging motion.

[0059] Further, in this embodiment, a plurality of swinging members 2 in the form of impellers are provided, the rotation axis directions of a plurality of swinging members 2 are arranged toward a first preset direction, and the rotation axis directions of the remaining plurality of swinging members 2 are arranged toward a second preset direction, and a plurality of first output shafts 4 are provided, and correspond to and are connected to the central axes of the plurality of swinging members 2 one by one. The first preset direction is specifically the front-to-back direction of the housing 1, and the second preset direction is specifically the left-to-right direction of the housing 1, so that during the process of starting and braking the ship, a portion of the swinging members 2 can capture the kinetic energy of the fluid and reduce the fluctuation of the fluid level, and during the turning process of the ship, another portion of the swinging members 2 can capture the kinetic energy of the fluid in another direction, thereby greatly improving the utilization rate of the kinetic energy of the fluid.

[0060] Specifically, in the exemplary embodiment, referring to Figure 5The swinging member 2 is formed in a plate shape, which adopts a flat plate structure. In some embodiments, it can be rectangular or circular. One end of the plate-shaped swinging member 2 is connected to the inner wall of the box body 1 through a bearing, and the other end can swing freely. The selection of the bearing should ensure the free swing and stability of the swinging member 2, while reducing friction and energy loss. The material selection of the swinging member 2 should have high strength and rigidity to ensure its stability and reliability under the fluctuation of the fluid.

[0061] Furthermore, in the exemplary embodiment, the average density of the plate-shaped swinging member 2 should be less than the density of the fluid in the box 1, so that during normal driving, the swinging member 2 can float above the fluid and swing with the fluctuation of the fluid. Furthermore, in this embodiment, the swinging member 2 is a hollow plate-shaped structure made of 304 stainless steel.

[0062] Furthermore, in the exemplary embodiment, two plate-shaped swing members 2 are provided, and two first output shafts 4 are provided, which correspond to and are connected to the two swing members 2 one by one. Specifically, the first output shaft passes through the box body and is coaxially fixedly connected to the rotating shaft of the swing member.

[0063] Furthermore, in some embodiments, the swing amplitude of the swing member 2 can be controlled by design to meet specific application requirements. Through reasonable design and material selection, the swing member 2 can swing within an appropriate range to absorb the kinetic energy of the fluid and reduce the fluctuation of the fluid.

[0064] Furthermore, in some embodiments, the position and number of the swing members 2 are designed according to specific application requirements. They can be evenly distributed inside the box 1 to minimize the fluctuation and impact of the fluid.

[0065] Furthermore, in the exemplary embodiment, referring to Figure 1 and Figure 5 In the first preset direction, that is, the front-to-back direction of the box body 1 , two swing members 2 are provided and are respectively located at the front and back sides of the box body 1 .

[0066] Furthermore, in the exemplary embodiment, corresponding to the positions of the two swinging members 2, the upper side walls of the box body 1 are respectively protruded upwards and form two active cavities for the swinging members 2 to move. When the box body 1 shakes or swings, the fluid inside it fluctuates, causing the swinging members 2 at the corresponding positions to swing. When the fluid flows through the active cavity, the fluid can be agitated due to the narrowness of the active cavity. Although the noise increases, the swing amplitude of the swinging member 2 can be expanded, thereby further improving the utilization rate of the fluid kinetic energy. Furthermore, in some embodiments, the connection between the inner wall of the box body 1 and the above-mentioned active cavity is set as an arc surface, so that when the fluid flows through the active cavity, the noise is reduced and the swing amplitude of the swinging member 2 can be expanded.

[0067] Specifically, in some embodiments, the follower assembly is connected to the swinging member 2, and can obtain the swinging force of the swinging member 2 and improve the stability of the swinging member 2 when it swings.

[0068] Further, in some embodiments, referring to Figure 2 and Figure 6 The follower assembly includes a third output shaft, a rack 31 and a driven gear 32. The third output shaft is sealed and penetrated through the housing 1; the rack 31 is specifically an arc-shaped rack 31, one end of which is fixedly connected to the end of the swing member 2 away from the first output shaft 4; the driven gear 32 is arranged in the housing 1 and is coaxially fixedly connected to the third output shaft, and the rack 31 is meshed with the driven gear 32. The swing kinetic energy of the swing member 2 can be transmitted to the third output shaft through the rack 31 and the driven gear 32.

[0069] Specifically, in the exemplary embodiment, referring to Figure 1 and Figure 5 The rotating assembly 5 is arranged in the box body 1 and can swing with the fluctuation of the fluid in the box body 1; the second output shaft 6 is sealed and penetrated on the box body 1 and connected with the swinging member 2, and the rotating assembly 5 can drive the second output shaft 6 to rotate.

[0070] Furthermore, in the exemplary embodiment, the rotating assembly 5 includes a rotating disk 51 and blades 52. The rotating disk 51 is disposed at the bottom of the housing 1, specifically at the middle of the bottom plate of the housing 1, and is coaxially fixedly connected to the second output shaft 6; a plurality of blades 52 are provided and are evenly fixed on the rotating disk 51 around the axis of the rotating disk 51.

[0071] In summary, compared with the prior art, the present application has at least the following beneficial effects:

[0072] Reducing fluid fluctuations: By arranging a swinging member 2 (such as an impeller or a plate) inside the liquid storage tank, the swinging member 2 can swing with the fluctuations of the fluid in the tank body 1.

[0073] Energy saving: By utilizing the swinging force of the swinging member 2, the fluctuation of the fluid can be converted into mechanical energy and transmitted to the first output shaft 4.

In this way, energy recovery and reuse can be achieved, reducing energy waste.

[0074] Increased stability: The design of the swing member 2 and the follower assembly can improve the stability of the fluid inside the tank. Through the coordination of the rack 31, the driven gear 32 and other structures, the movement of the swing member 2 can be better fixed and controlled, further reducing the fluctuation of the fluid and improving the stability of the ship.

[0075] That is, this solution can reduce the fluctuation of the fluid in the storage tank, reduce noise and vibration, save energy, improve ship stability, and can be integrated with other components to build a fully functional ship system.

The specific structure of the power generation device and how to use the first output shaft 4, the second output shaft 6 and the third output shaft to generate electricity belong to the existing technology and will not be repeated here.

[0078] Specifically, the speed increasing gear set: the first output shaft 4, the second output shaft 6 and the third output shaft are connected to the generator through the speed increasing gear set, and the speed increasing gear set is used to amplify the rotation speed of the first output shaft 4, the second output shaft 6 and the third output shaft, and improve the power generation efficiency of the generator.

The inert component can fill the box body 1 with inert gas to avoid the risk of combustion or explosion when generating electricity through the oil tank.

[0083] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application.
