Description

Technical Field

[0001] This disclosure belongs to the field of hydraulic equipment technology, and specifically relates to an anti-sway oil tank. Background Technology

[0002] Ships are affected by wind and waves during navigation, causing the hydraulic oil in the tank to slosh and potentially leading to cavitation in hydraulic equipment. To avoid this, anti-sloshing oil tanks are generally used.

[0003] In related technologies, an anti-sway oil tank includes a tank body and an anti-sway component, which is located inside the tank body and connected to it. The anti-sway component includes multiple partitions, which are fixedly arranged side-by-side inside the tank body to divide the interior into multiple cavities of equal volume. Each partition has a through-hole at its bottom, connecting adjacent cavities. When the anti-sway oil tank experiences vibrations in the environment, these partitions can suppress the cumulative fluctuations of the oil flow, achieving a certain degree of anti-sway function.

[0004] However, the anti-sloshing effect of the above-mentioned anti-sloshing fuel tanks is poor and they are not suitable for environments with strong winds and waves. Summary of the Invention

[0008] In another implementation of this disclosure, the support assembly includes a universal rotary joint and a support base; the support base is connected to the inner wall of the outer housing; the universal rotary joint is located between the inner housing and the support base, and the universal rotary joint is connected to both the inner housing and the support base.

[0009] In another implementation of this disclosure, the inner casing wall has a first oil outlet hole; the outer casing wall has a second oil outlet hole; the universal rotary joint includes a first port and a second port, the first port of the universal rotary joint is connected to the first oil outlet hole, and the second port of the universal rotary joint is connected to the second oil outlet hole.

[0010] In another implementation of this disclosure, the bottom of the inner box is spherical, and the rotation axis of the inner box is perpendicular to the bottom of the spherical crown; the support assembly further includes multiple telescopic mechanisms, which are arranged symmetrically about the rotation axis of the inner box, the fixed end of the telescopic mechanism is connected to the inner wall of the outer box, and the moving end of the telescopic mechanism is in sliding contact with the bottom of the inner box.

[0011] In another implementation of this disclosure, a plurality of the telescopic mechanisms are arranged around the universal joint.

[0012] In another implementation of this disclosure, the telescopic mechanism includes a base, a hydraulic cylinder, and a support head. The base is connected to the inner wall of the outer housing, the cylinder body of the hydraulic cylinder is connected to the base, the piston rod of the hydraulic cylinder is connected to the support head, and the support head is rotatably in contact with the arc-shaped outer wall at the bottom of the inner housing.

[0013] In another implementation of this disclosure, the anti-sway oil tank further includes a hollow baffle plate in the middle, the baffle plate being located at the top of the inner tank and connected to the inner wall of the inner tank.

[0014] In another implementation of this disclosure, the oil baffle plate forms an angle with the inner wall of the inner box, the angle being 45°-75°.

[0015] In another implementation of this disclosure, the anti-sway oil tank further includes an oil inlet pipe connected to the outer casing.

This can prevent the oil from shaking violently and prevent the hydraulic oil equipment from sucking in air.

[0019] In other words, the anti-sway fuel tank provided in this embodiment can maintain its original vertical position even if the ship tilts and rolls, thereby maintaining a stable fuel supply capacity. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0041] This disclosure provides an anti-sloshing fuel tank, see [link / reference]. Figure 1 The anti-sway oil tank includes an outer casing 1, an inner casing 2, a support assembly 4, and an electromagnetic assembly 5. The inner casing 2 is located inside the outer casing 1.

[0042] The support assembly 4 is located inside the outer housing 1. The support assembly 4 is connected to the inner housing 2 and the outer housing 1 respectively, so that the inner housing 2 can rotate relative to the support assembly 4. The rotation axis of the inner housing 2 passes through the support assembly 4.

[0043] The electromagnetic component 5 is located between the inner wall of the outer casing 1 and the outer wall of the inner casing 2. The electromagnetic component 5 is configured to drive the inner casing 2 to rotate after being energized.

[0044] When the anti-sway oil tank provided in this embodiment is used on a ship, since the anti-sway oil tank includes an outer casing 1, an inner casing 2, a support assembly 4, and an electromagnetic assembly 5, oil can be stored inside the inner casing 2 to supply oil to hydraulic equipment.

[0045] Since the electromagnetic component 5 is located between the inner wall of the outer housing 1 and the outer wall of the inner housing 2, and the electromagnetic component 5 is configured to drive the inner housing 2 to rotate after being energized, when the electromagnetic component 5 is energized, the inner housing 2 will rotate relative to the support component 4. Thus, when the rotation speed of the inner housing 2 reaches a certain value, the inner housing 2 will have certain gyroscopic characteristics. That is, regardless of whether the outer housing 1 shakes, the inner housing 2 will always be in a vertical direction and will not tilt. The inner housing 2 has sufficient anti-tilting properties, and the oil inside the inner housing 2 will not tilt. Instead, a vortex with a low center and a high periphery will be formed inside the inner housing 2. This can prevent the oil from shaking violently and prevent the hydraulic oil equipment from sucking in air.

[0046] In other words, the anti-sway oil tank provided in this embodiment can maintain its original vertical state even if the ship tilts and rocks, thereby maintaining a stable oil supply capacity.

[0047] See also Figure 1 Optionally, the support assembly 4 includes a universal joint 41 and a support base 42. The support base 42 is connected to the inner wall of the outer housing 1. The universal joint 41 is located between the inner housing 2 and the support base 42, and is connected to both the inner housing 2 and the support base 42.

[0048] In the above implementation, the support component 4 is set as a universal rotary joint 41 and a support base 42. In this way, the rotational connection between the outer housing 1 and the inner housing 2 can be realized by rotating between the support base 42 and the universal rotary joint 41.

[0049] For example, when the universal rotary joint 41 rotates, the rotation amplitude is small, which can control the rotation amplitude of the inner box 2, making the rotation process of the inner box 2 more stable and preventing the oil inside the inner box 2 from splashing due to its violent rotation.

[0050] Optionally, the universal rotary joint 41 is a stainless steel structural component.

[0051] The universal rotary joint 41 is made of stainless steel, which gives it high-temperature and wear-resistant properties and ensures airtightness of the connection, allowing it to rotate effectively and continuously.

[0052] Of course, the universal rotary joint 41 can also be a titanium alloy structural component, which can give the universal rotary joint 41 high strength and ensure that the universal rotary joint 41 can rotate effectively and continuously.

[0053] For example, the support base 42 includes two side plates and a top plate. The two side plates are arranged opposite to each other and connected to the same surface of the top plate. The top plate is arranged opposite to the inner wall of the outer casing 1. The top plate is provided with a spherical groove that mates with the universal rotary joint 41. The universal rotary joint 41 is slidably located in the spherical groove.

[0054] The above structure allows the support base 42 to rotate with the universal rotary joint 41, so that the inner box 2 can rotate freely on the support base 42.

[0055] Optionally, the inner housing 2 has a first oil outlet 20 on its wall. The outer housing 1 has a second oil outlet 10 on its wall. The universal rotary joint 41 includes a first port and a second port. The first port of the universal rotary joint 41 communicates with the first oil outlet 20, and the second port of the universal rotary joint 41 communicates with the second oil outlet 10.

[0056] In the above implementation, the universal rotary joint 41 is connected to the first oil outlet 20 and the second oil outlet 10, so that the oil in the inner box 2 can be completely discharged through the universal rotary joint 41, ensuring that the inner box 2 can smoothly supply oil to the hydraulic equipment.

[0057] For example, the anti-sway oil tank also includes an oil outlet pipe 6, which is partially located inside the outer housing 1. One end of the oil outlet pipe 6 is connected to the second port of the universal rotary joint 41, and the other end of the oil outlet pipe 6 extends out of the outer housing 1 to supply oil to the hydraulic equipment.

[0058] The oil outlet pipe 6 can deliver the oil flowing out of the universal rotary joint 41 to the hydraulic equipment so as to drive the hydraulic equipment to work.

[0059] For example, the oil outlet pipe 6 is made of steel pipe, which can greatly improve the heat resistance and pressure resistance of the oil outlet pipe 6, and ensure that the oil outlet pipe 6 will not easily deform and affect the oil supply.

[0060] Optionally, the inner box 2 is spherical, and the rotation axis of the inner box 2 is perpendicular to the bottom of the spherical crown. The support assembly 4 also includes multiple telescopic mechanisms 43. The multiple telescopic mechanisms 43 are arranged symmetrically about the rotation axis of the inner box 2. The fixed end of the telescopic mechanism 43 is connected to the inner wall of the outer box 1, and the moving end of the telescopic mechanism 43 is in sliding contact with the bottom of the inner box 2.

[0061] In the above implementation, multiple telescopic mechanisms 43 are provided, so that the inner box 2 can be supported by multiple telescopic mechanisms 43 together, so that the inner box 2 will not tip over when it is not rotating.

[0062] For example, multiple telescopic mechanisms 43 are arranged around the universal joint 41. This facilitates the multiple telescopic mechanisms to assist the universal joint 41 in supporting the inner housing 2.

[0063] Optionally, the telescopic mechanism 43 includes a base 431, a hydraulic cylinder 432, and a support head 433. The base 431 is connected to the inner wall of the outer housing 1, the cylinder body of the hydraulic cylinder 432 is connected to the base 431, the piston rod of the hydraulic cylinder 432 is connected to the support head 433, and the support head 433 is rotatably in contact with the arc-shaped outer wall at the bottom of the inner housing 2.

[0064] In the above implementation, the telescopic mechanism 43 is configured as a base 431, a hydraulic cylinder 432, and a support head 433. The base 431 can be used to fix the hydraulic cylinder 432 to the bottom of the outer casing 1. Simultaneously, the automatic extension and retraction of the hydraulic cylinder 432 enables the automatic extension and retraction of the telescopic mechanism 43, ensuring that the telescopic mechanism 43 is in constant contact with the bottom of the inner casing 2, thus supporting the inner casing 2. The support head 433 is connected to the piston rod of the hydraulic cylinder 432, which reduces friction between the inner casing 2 and the telescopic mechanism 43, thereby ensuring the free rotation of the inner casing 2.

[0065] Figure 2 This is a schematic diagram of the telescopic structure in its contracted state, as provided in an embodiment of this disclosure. Figure 3 This is a structural diagram of the telescopic structure in its extended state provided in the embodiments of this disclosure, combined with... Figure 2 and Figure 3 In this embodiment, to ensure that the support head 433 is in constant contact with the bottom of the inner housing 2, when the outer housing 1 is not tilted, the supporting force of all the hydraulic cylinders 432 is the same as the weight of the inner housing 2. The hydraulic cylinders 432 maintain pressure continuously. When the outer housing 1 tilts, the pressure of the inner housing 2 on the hydraulic cylinders 432 changes because the outer housing 1 is unbalanced. This causes the piston rods of some hydraulic cylinders 432 to retract and the piston rods of some hydraulic cylinders 432 to extend, ensuring that all the support heads 433 are in constant contact with the bottom of the inner housing 2.

[0066] Optionally, the support head 433 is a universal ball bearing. The outer ring of the universal ball bearing is connected to the piston rod of the hydraulic cylinder 432, and the inner ball of the universal ball bearing is in contact with the bottom of the inner housing 2.

[0067] By allowing the universal ball bearing to rotate freely, the sliding contact between the support head 433 and the inner housing 2 is changed to a rolling contact, thereby further reducing the friction between the support head 433 and the inner housing 2, allowing the inner housing 2 to rotate flexibly.

[0068] The support head 433 can also be configured as a bullseye wheel. The bullseye wheel can be made of stainless steel balls, nylon balls, or carbon steel balls, possessing good toughness and strong fatigue resistance. The bullseye wheel rotates flexibly, requiring virtually no regular lubrication, making operation and maintenance convenient.

[0069] Of course, the support head 433 can also be other structural components, such as a universal joint. As long as the support head 433 can slide freely in contact with the inner housing 2, it is acceptable.

[0070] See you again Figure 1 For example, there may be four telescopic mechanisms 43, which are arranged circumferentially at intervals along the central axis of the inner housing 2. The universal joint 41 is located at the lowest position of the bottom of the inner housing (that is, the universal joint 41 is located on the central axis of the inner housing 2).

[0071] Four telescopic mechanisms 43 are arranged circumferentially along the central axis of the inner box 2. This provides stable support for the inner box 2.

[0072] Furthermore, the universal rotary joint 41 is positioned at the lowest point of the arc-shaped outer wall at the bottom of the inner housing, which allows the inner housing 2 to maintain balance when rotating around the universal rotary joint 41 as a fulcrum.

[0073] For example, the outer box 1 is a cylindrical structure closed at both ends, and the outer box 1 and the inner box 2 are arranged coaxially.

[0074] In the above implementation, the outer casing 1 is used to cooperate with the inner casing 2 to protect the inner casing 2. The inner casing 2 is designed as a cylindrical structure, which makes the inner casing 2 easier to rotate and reduces air resistance.

[0075] For example, the inner housing 2 is a silicon steel structural component. This allows the inner housing 2 to have high magnetic permeability and thus low hysteresis loss. This effectively reduces energy loss and waste between the electromagnetic components 5.

[0076] For example, the outer casing 1 is a steel structural component, which can increase the structural strength of the outer casing 1 and extend its service life.

[0077] See also Figure 1 Optionally, the electromagnetic component 5 includes multiple wound coils 51 and multiple permanent magnets 52. The wound coils 51 are arranged around the rotation axis of the inner housing 2 on the inner wall of the outer housing 1. Each permanent magnet 52 is arranged around the rotation axis of the inner housing 2 on the outer wall of the inner housing 2, and the permanent magnets 52 are spaced apart from the wound coils 51.

[0078] In the above implementation, the electromagnetic component 5 is set as a wound coil 51 and a permanent magnet 52. This makes the inner box 2 similar to the rotor structure in a motor, and the outer box 1 similar to the stator structure in a motor. Using the principle of electromagnetic induction, the inner box 2 can rotate freely relative to the outer box 1 when energized.

[0079] For example, the wound coil 51 may be a copper coil.

[0080] Because copper has good electrical conductivity, the wound coil 51 can convert more electrical energy into magnetic energy when energized, which will make the inner box 2 rotate faster relative to the outer box 1, thus improving the stability of the inner box 2.

[0081] When the winding coil 51 is a copper coil, a protective layer can be provided on the outside of the winding coil 51, that is, the winding coil 51 is a copper enameled wire.

[0082] Of course, the material of the winding coil 51 can also be aluminum.

[0083] Because aluminum is lighter, using an aluminum coil 51 helps reduce its weight. At the same time, the oxide film on the aluminum surface has corrosion-resistant and insulating properties, which can extend the service life of the coil 51.

[0084] For example, the permanent magnet 52 uses a material commonly used in the rotor of a permanent magnet motor, such as ferrite. This ensures that the permanent magnet 52 has strong magnetism, and when the winding coil 51 is energized, the permanent magnet 52 can rotate rapidly along with the inner housing 2.

[0085] Of course, the arrangement of permanent magnets 52 can refer to the structure of the rotor in a permanent magnet motor. For example, multiple permanent magnets 52 can be arranged circumferentially around the central axis of the inner housing 2, and the magnetic poles of two adjacent permanent magnets 52 can be arranged in opposite directions. The magnetic poles of each permanent magnet 52 can be opposite in the radial direction of the inner housing 2.

[0086] In addition, in order to facilitate the control of the current flowing through the winding coil 51 so that the winding coil 51 can generate a rotating magnetic field, the winding coil 51 can be connected to a frequency converter, and the current magnitude and frequency of the winding coil 51 can be easily controlled through the frequency converter.

[0087] Figure 4 This is a schematic diagram of the arrangement of permanent magnets provided in the embodiments of this disclosure, combined with... Figure 4 The magnetic pole arrangement of the permanent magnet 52 can be as shown in the figure. The magnetic poles of two adjacent permanent magnets 52 are exactly opposite, that is, from the inside to the outside along the radial direction of the inner box 2. Among two adjacent permanent magnets 52, one is NS and the other is SN.

[0088] Similarly, the arrangement of the wound coils 51 can refer to the stator structure in a permanent magnet motor, i.e., the outer wall of the outer casing 1 is connected to a ring-shaped iron core, and the iron core has multiple coil mounting slots. The extension direction of the coil mounting slots is the same as the axial direction of the outer casing 1. The coils (i.e., copper coils) are wound in the corresponding coil mounting slots to form multiple wound coils. The wound coils 51 can be arranged in a three-phase four-pole configuration, using a single-layer chain winding. The copper wire generates a four-pole rotating magnetic field (with four N poles and four S poles, corresponding to the four permanent magnets 52).

[0089] After passing a three-phase alternating current through the wound coil 51, the wound coil 51 forms a rotating magnetic field (see...). Figure 5 The permanent magnet 52 is subjected to magnetic force in the rotating magnetic field, causing the permanent magnet 52 to rotate at a speed n in the rotating magnetic field.

[0090] See you again Figure 1 Optionally, the anti-sway oil tank also includes a hollow baffle plate 7 in the middle, which is located at the top of the inner tank 2 and is connected to the inner wall of the inner tank 2.

[0091] In the above implementation, a hollow oil baffle 7 is provided at the top of the inner box 2. In this way, when the inner box 2 is rotating, the oil inside the inner box 2 will rise up along the side wall of the inner box 2 due to the effect of rotation. The oil baffle 7 can effectively prevent the oil from rising and overflowing.

[0092] Optionally, the oil baffle 7 forms an angle α of less than 90° with the inner wall of the inner box 2.

[0093] In the above implementation, the above settings can prevent oil from accumulating on the upper surface of the oil baffle 7 when adding oil to the opening 21 of the inner box 2, so that the oil spilled on the oil baffle 7 can flow smoothly into the interior of the inner box 2.

[0094] For example, the included angle α between the oil baffle 7 and the inner wall of the inner box 2 can be any angle within the range of 45°-75°.

[0095] Figure 5 for Figure 1 Top view, combined Figure 5 In this embodiment, the oil baffle 7 is a ring structure, and the oil baffle 7 is arranged coaxially with the inner box 2.

[0096] This ensures that the interior of the inner box 2 is balanced about the central axis of the inner box 2, which is conducive to the stable rotation of the inner box 2.

[0097] For example, the oil baffle 7 is a steel structural component, and the oil baffle 7 is connected to the inner box 2 by welding. This increases the connection strength between the two.

[0098] Optionally, the anti-sway oil tank also includes an oil inlet pipe 8, which is connected to the outer casing 1. One end of the oil inlet pipe 8 is located outside the outer casing 1, and the other end of the oil inlet pipe 8 is located inside the outer casing 1 and faces the opening 21 of the inner casing 2.

[0099] The oil inlet pipe 8 is used to introduce oil into the inner housing 2 so that it can supply oil to other hydraulic equipment through the inner housing 2.

[0100] The following is in conjunction with the appendix Figure 6-11Here is a brief introduction to the working principle of the anti-sway fuel tank provided in this embodiment:

[0101] When the electromagnetic component 5 is not energized, the state of the anti-sway oil tank is as follows: Figure 6 and 7 As shown, oil is injected into the inner housing 2 through the oil inlet pipe 8. At this time, the inner housing 2 is supported by the universal joint 41 installed on the support base 42 and four oil cylinders 432 installed at the bottom of the outer housing 1, so that the inner housing 2 is placed horizontally without tilting.

[0102] Then, the external control system energizes the winding coil 51 of the electromagnetic component 5. At this time, the outer casing 1 acts as the stator of the motor, and the permanent magnet 52 on the inner casing 2 acts as the rotor of the motor. Since the center of the bottom of the inner casing 2 is connected by a universal rotary joint 41, and the tops of the four telescopic mechanisms supporting the bottom of the inner casing 2 are universal ball bearings, the inner casing 2 can rotate freely (according to...). Figure 9 (Rotating in the direction of rotation) controls the current of the winding coil 51, causing the rotation speed of the inner box 2 to gradually increase.

[0103] When the rotational speed of the inner chamber 2 rises to the set "low speed" state (e.g., 300 r / min), such as Figure 8 and 9 As shown, the inner housing 2 already possesses certain gyroscope characteristics at this point.

[0104] When the rotational speed of the inner casing 2 rises to the set "normal speed" state (e.g., 1800 r / min), such as Figure 10 At this point, the rotational speed of the inner box 2 has given it sufficient anti-tipping capability.

[0105] When the ship tilts and rolls, such as Figure 11 The rotating inner chamber 2 can still maintain its original vertical position, thus enabling the inner chamber 2 to maintain a stable oil supply capacity.

[0106] Therefore, the anti-sway oil tank in this application is not only simple in structure and easy to use, but also has a gyroscopic effect when the oil is stored in the inner tank 2 during operation and the inner tank 2 rotates at high speed.

[0107] When the outer casing 1 installed on the deck shakes or tilts at any angle, the inner casing 2 remains vertical, thus completely preventing the oil inside the inner casing 2 from sloshing and allowing the inner casing 2 to continuously supply oil to the hydraulic equipment.

[0108] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
