Description

Technical Field

[0001] The present invention relates to the technical field of anti-slosh storage tank equipment for propellants, and particularly to an anti-slosh storage tank for propellants in sea-launched rocket fuel filling. Background Art

[0002] Before a sea-launched rocket is launched, it is necessary to fill fuels such as propellants in the storage tank into the rocket. Since it is a sea-launched rocket, the shaking of the ship will cause the filling storage tank to shake. When the storage tank shakes, the fuel propellants inside the storage tank will also shake at the same time, which may lead to unstable delivery flow rate of the propellants, affect the delivery efficiency of the fuel, and further cause delays in rocket launches. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an anti-slosh storage tank for propellants in sea-launched rocket fuel filling, including a tank body. A support frame is fixedly connected to the outer surface of the tank body. A feed port is opened at the top of the tank body, and a filling port is opened at the bottom of the tank body. An anti-slosh component is arranged inside the tank body. The anti-slosh component includes a liquid separation plate. One side of the inner wall of the tank body close to the liquid separation plate is fixedly connected with a liquid separation column. The number of the liquid separation columns is several. One side of the inner wall of the tank body on the back is fixedly connected with a first liquid separation plate. The number of the first liquid separation plates is several;

[0004] A separation component, the separation component includes a first hydraulic cylinder. The bottom of the first hydraulic cylinder is fixedly connected with a moving block. The right side of the moving block is fixedly connected with a first spring. The right side of the first spring is fixedly connected with a telescopic block. The number of the first springs is two. The two first springs are symmetrically arranged. The number of the telescopic blocks is two. The number of the moving blocks is several. In the present invention, when fuel is filled into the tank body from the feed port, part of the fuel in the tank body will enter the liquid separation plate. When the tank body shakes, the fuel in this part will shake at the same time. The shaking fuel will flow along the inner wall of the liquid separation plate. At the same time, under the action of the liquid separation column, the fuel will be split. The split fuel will flow along the inner walls on both sides of the liquid separation plate. The fuel flowing along the left inner wall will change its flow direction in the arc-shaped channel formed by the liquid separation plate and the liquid separation column. At the same time, the fuel flowing along the right inner wall of the liquid separation plate will collide with the fuel whose flow direction has changed, causing the fuel in this part to form a vortex at the intersection point, reducing the continuous flow of the fuel. At the same time, the setting of the first liquid separation plate will divide the fuel into a main stream and a tributary. The main stream will move along the outer wall of the liquid separation plate, and the tributary will push the moving block and then turn back to collide with the main stream, forming a vortex at the intersection point, and the flow kinetic energy will decrease, so that the fuel in the tank can quickly reduce its flow after the tank body shakes, reduce the shaking of the fuel in the tank, and avoid the problem that the continuous shaking of the fuel affects the subsequent fuel delivery efficiency;

[0005] A connecting pipe 1 is fixedly connected to the top of the first hydraulic cylinder. A second hydraulic cylinder is fixedly connected to the left side of the connecting pipe 1. A slider is rotatably connected to the left side of the second hydraulic cylinder through a pin shaft. A first rotating plate is rotatably connected to the bottom of the first liquid separation plate on the right side through a pin shaft. When the fuel inside the tank body shakes, the fuel shaking to the right will come into contact with the first liquid separation plate and flow along the first liquid separation plate at the same time. The flowing fuel will push the moving block. The movement of the moving block will cause the fuel in the first hydraulic cylinder to be input into the second hydraulic cylinder through the connecting pipe 1, causing the second hydraulic cylinder to extend. The extension of the second hydraulic cylinder will cause the first rotating plate to rotate, making one end of it contact the outer surface of the liquid separation plate, forming a compartment below this part, reducing the flow of the bottom undercurrent. Since the number of the separation components is two, compartments will be formed on both the left and right sides of the bottom of the tank body. The fuel that cannot flow significantly will enter the liquid separation plate, and under the action of the liquid separation plate and the liquid separation column, the flow kinetic energy is reduced. The setting of this part can form a compartment at the bottom of the tank body, effectively reducing the flow of the undercurrent at the bottom of the fuel in the tank, playing an auxiliary anti-shaking effect, making the flowing fuel can only enter the liquid separation plate, reducing the shaking of the fuel.

[0006] Preferably, a second liquid separation plate is fixedly connected to the back side of the inner wall of the tank body near the first liquid separation plate. A notch is opened on the right side of the second liquid separation plate. The number of the second liquid separation plates is several. Liquid discharge grooves are opened at the top of the liquid separation plate. The number of the liquid discharge grooves is two.

[0007] Preferably, a slideway is opened at the bottom of the first rotating plate. The inner wall of the slideway contacts the outer surface of the slider. A second spring is fixedly connected to the top of the moving block. The top of the second spring is fixedly connected to the bottom of the first liquid separation plate. The right side of the second liquid separation plate contacts the left side of the telescopic block on the left.

[0008] Preferably, a rotating rod is rotatably connected to the bottom of the first rotating plate through a pin shaft. A second rotating plate is rotatably connected to the outer surface of the rotating rod through a pin shaft. An arc-shaped plate is fixedly connected to the top of the second rotating plate. The number of the arc-shaped plates is several. The several arc-shaped plates are arranged in a horizontal array. The side of the second rotating plate away from the rotating rod is rotatably connected to the inner wall of the tank body. In the present invention, when the first rotating plate rotates, it will drive the rotating rod to move upward synchronously. Since one side of the second rotating plate is rotatably connected to the inner wall of the tank body and the other side is rotatably connected to the rotating rod, the first rotating plate will drive several second rotating plates to move synchronously while rotating upward until the second rotating plate is level with the first rotating plate. The several arc-shaped plates fixedly connected to the top of the second rotating plate can make the undercurrent turn back after contacting this position at the bottom, making the turned-back undercurrent collide with the flowing undercurrent, and reducing the flow kinetic energy of the undercurrent restricted at the bottom again. The shaking at the bottom of the tank body is reduced, which can play an auxiliary role in reducing the shaking of the whole tank body to a stationary state later.

[0009] Preferably, the number of the second rotating plates is several, and the several second rotating plates are symmetrically arranged. The bottom of the first liquid separation plate on the left is rotatably connected to a third rotating plate through a pin shaft. The top of the third rotating plate is fixedly connected to two second sealing blocks, and the two second sealing blocks are symmetrically arranged. The top of the first rotating plate is fixedly connected to two first sealing blocks.

[0010] Preferably, a liquid increasing component is arranged above the tank body. The liquid increasing component includes a first telescopic cylinder. The bottom of the first telescopic cylinder is fixedly connected to the top of the upper moving block. The top of the first telescopic cylinder is fixedly connected to a second connecting pipe. The bottom of the second connecting pipe is fixedly connected to a second telescopic cylinder. The bottom of the second telescopic cylinder is fixedly connected to a pressing plate.

[0011] Preferably, a one-way valve is fixedly connected to the top of the pressing plate. A fuel cylinder is fixedly connected to one side of the tank body near the filling port. The inner wall of the fuel cylinder is in contact with the outer surface of the pressing plate. A liquid outlet is formed at the bottom of the fuel cylinder. A discharge pipe is fixedly connected to the bottom of the liquid outlet. The number of the liquid increasing components is two, and the two liquid increasing components are symmetrically arranged. When there is more fuel inside the tank body in the present invention, by connecting an additional fuel pipe to the one-way valve, when the tank body shakes, the liquid level of the fuel inside the tank will also shake. The shaking of the liquid level will impact the upper moving block and cause it to move. The movement of the moving block will cause the first telescopic cylinder to convey the fuel inside it to the second telescopic cylinder through the second connecting pipe. The increase in the fuel in the second telescopic cylinder will cause the pressing plate to push the fuel in the fuel cylinder to be discharged from the discharge pipe. The discharged fuel will enter the tank body and gradually increase the height of the fuel liquid level inside it. Since the liquid level rises, the moving free surface of the fuel will be reduced. The reduction of the free surface will reduce the shaking of the fuel, thereby reducing the overall shaking of the fuel inside the tank body. [[ID=?]]

[0012] The present invention has the following beneficial effects:

[0013] (1)In the present invention, fuel is filled into the tank from the feed port. Part of the fuel in the tank will enter the liquid separation plate. When the tank shakes, the fuel in this part will shake simultaneously. The shaking fuel will flow along the inner wall of the liquid separation plate. At the same time, under the action of the liquid separation column, the fuel will be split. The split fuel will flow along the inner walls on both sides of the liquid separation plate. The fuel flowing along the left inner wall will change its flow direction in the arc-shaped channel formed by the liquid separation plate and the liquid separation column. At the same time, the fuel flowing along the right inner wall of the liquid separation plate will collide with the fuel whose flow direction has changed, causing the fuel at this part to form a vortex at the intersection point, reducing the continuous flow of the fuel. At the same time, the setting of the first liquid separation plate will divide the fuel into a main flow and a tributary flow. The main flow will move along the outer wall of the liquid separation plate, and the tributary flow will push the moving block and then turn back to collide with the main flow, forming a vortex at the intersection point, and the flow kinetic energy will decrease. After the tank shakes, the fuel in the tank can quickly reduce its flow, reduce the shaking of the fuel in the tank, and avoid the problem that the continuous shaking of the fuel affects the subsequent fuel delivery efficiency.

[0014] (2)When the fuel inside the tank shakes in the present invention, the fuel shaking to the right will contact the first liquid separation plate and flow along the first liquid separation plate at the same time. The flowing fuel will push the moving block, and the movement of the moving block will cause the fuel in the first hydraulic cylinder to be input into the second hydraulic cylinder through the first connecting pipe, causing the second hydraulic cylinder to extend. The extension of the second hydraulic cylinder will cause the first rotating plate to rotate, making one end of it contact the outer surface of the liquid separation plate, forming a compartment below this part and reducing the flow of the bottom undercurrent. Since the number of the separation components is two, compartments will be formed on both the left and right sides of the tank bottom. The fuel that cannot flow substantially will enter the liquid separation plate, and under the action of the liquid separation plate and the liquid separation column, the flow kinetic energy will be reduced. The setting of this part can form a compartment at the tank bottom, effectively reducing the flow of the bottom undercurrent of the fuel in the tank, playing an auxiliary anti-shaking effect, making the flowing fuel only enter the liquid separation plate and reducing the shaking of the fuel.

[0015] (3)When the first rotating plate rotates, it will drive the rotating rod to move upward synchronously. Since one side of the second rotating plate is rotatably connected to the inner wall of the tank and the other side is rotatably connected to the rotating rod, the first rotating plate will drive a plurality of second rotating plates to move synchronously when rotating upward until the second rotating plates are level with the first rotating plate. A plurality of arc-shaped plates fixed to the top of the second rotating plates can turn back after the bottom undercurrent contacts this position, causing the turned-back undercurrent to collide with the flowing undercurrent, and once again reducing the flow kinetic energy of the bottom undercurrent restricted at the bottom. The shaking of the tank bottom is reduced, which can play an auxiliary role in reducing the overall shaking of the subsequent tank to a stationary state and improving the anti-shaking effect.

[0016] When there is a large amount of fuel inside the tank body, the present invention connects an additional fuel pipe to the check valve. When the tank body shakes, the liquid level of the fuel in the tank will also shake. The shaking of the liquid level will impact the moving block located above, causing it to move. The movement of the moving block will cause the first telescopic cylinder to transport the fuel inside it to the second telescopic cylinder through the second connecting pipe. The increase in the fuel in the second telescopic cylinder will cause the pressing plate to push the fuel in the fuel cylinder to be discharged from the discharge pipe. The discharged fuel will enter the tank body and gradually increase the height of the fuel liquid level inside it. Since the liquid level rises, the free surface of the fuel movement will be reduced. The reduction of the free surface will reduce the fuel shaking, thereby reducing the overall fuel shaking inside the tank body. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Example 1. Please refer to Figures 1 - 4 , the present invention is an anti-slosh storage tank for filling propellants of a sea rocket fuel, including a tank body 1. A support frame 11 is fixedly connected to the outer surface of the tank body 1. A feed inlet 12 is opened at the top of the tank body 1. A filling port 13 is opened at the bottom of the tank body 1. An anti-slosh component 2 is arranged inside the tank body 1. The anti-slosh component 2 includes a liquid separation plate 21. A liquid separation column 212 is fixedly connected to one side of the inner wall of the tank body 1 close to the liquid separation plate 21. The number of the liquid separation columns 212 is several. A first liquid separation plate 22 is fixedly connected to the back of the inner wall of the tank body 1. The number of the first liquid separation plates 22 is several;

[0030] The separating component 3 includes a first hydraulic cylinder 31. A moving block 33 is fixedly connected to the bottom of the first hydraulic cylinder 31. A first spring 331 is fixedly connected to the right side of the moving block 33. A telescopic block 332 is fixedly connected to the right side of the first spring 331. The number of the first springs 331 is two, and the two first springs 331 are symmetrically arranged. The number of the telescopic blocks 332 is two, and the number of the moving blocks 33 is several. In the present invention, fuel is filled into the tank body 1 from the feed port 12. Part of the fuel in the tank body 1 will enter the liquid separation plate 21. When the tank body 1 shakes, the fuel in this part will shake simultaneously. The shaking fuel will flow along the inner wall of the liquid separation plate 21. At the same time, under the action of the liquid separation column 212, the fuel will be split. The split fuel will flow along the inner walls on both sides of the liquid separation plate 21. The fuel flowing along the left inner wall will change its flow direction in the arc-shaped channel formed by the liquid separation plate 21 and the liquid separation column 212. At the same time, the fuel flowing along the right inner wall of the liquid separation plate 21 will collide with the fuel whose flow direction has changed, causing the fuel at this part to form a vortex at the intersection point, reducing the continuous flow of the fuel. At the same time, the setting of the first liquid separation plate 22 will divide the fuel into a main stream and a tributary. The main stream will move along the outer wall of the liquid separation plate 21, and the tributary will push the moving block 33 and then turn back to collide with the main stream, forming a vortex at the intersection point, and the flow kinetic energy decreases, so that the fuel in the tank can quickly reduce its flow after the tank shakes, reducing the shaking of the fuel in the tank, and avoiding the problem that the continuous shaking of the fuel affects the subsequent fuel delivery efficiency;

[0031] A first connecting pipe 311 is fixedly connected to the top of the first hydraulic cylinder 31. A second hydraulic cylinder 32 is fixedly connected to the left side of the first connecting pipe 311. A slider 321 is rotatably connected to the left side of the second hydraulic cylinder 32 through a pin shaft. A first rotating plate 322 is rotatably connected to the bottom of the right liquid separation plate 22 through a pin shaft. When the fuel inside the tank body 1 shakes in the present invention, the fuel shaking to the right will contact the first liquid separation plate 22 and flow along the first liquid separation plate 22 at the same time. The flowing fuel will push the moving block 33. The movement of the moving block 33 will cause the fuel in the first hydraulic cylinder 31 to be input into the second hydraulic cylinder 32 through the first connecting pipe 311, causing the second hydraulic cylinder 32 to extend. The extension of the second hydraulic cylinder 32 will cause the first rotating plate 322 to rotate, making one end of it contact the outer surface of the liquid separation plate 21, forming a compartment below this part and reducing the flow of the bottom undercurrent. Since the number of the separating components 3 is two, compartments will be formed on both the left and right sides of the bottom of the tank body 1. The fuel that cannot flow significantly will enter the liquid separation plate 21. Under the action of the liquid separation plate 21 and the liquid separation column 212, the flow kinetic energy is reduced. The setting of this part can form compartments at the bottom of the tank, effectively reducing the flow of the bottom undercurrent of the fuel in the tank, playing an auxiliary anti-shaking effect, enabling the flowing fuel to only enter the liquid separation plate 21 and reducing the shaking of the fuel.

[0032] On the back side of the inner wall of the tank body 1 near one side of the liquid separation plate 22, a liquid separation plate 221 is fixedly connected. A notch 222 is formed on the right side of the liquid separation plate 221. The number of the liquid separation plates 221 is several. An liquid outlet groove 211 is formed at the top of the liquid separation plate 21. The number of the liquid outlet grooves 211 is two.

[0033] A slideway is formed at the bottom of the first rotating plate 322. The inner wall of the slideway is in contact with the outer surface of the slider 321. A second spring 34 is fixedly connected to the top of the moving block 33. The top of the second spring 34 is fixedly connected to the bottom of the liquid separation plate 22. The right side of the liquid separation plate 221 is in contact with the left side of the telescopic block 332 located on the left.

[0034] Example 2, please refer to Figures 5 - 8 , the present invention is an anti-slosh storage tank for sea-launched rocket fuel filling propellant. On the basis of Example 1, the bottom of the first rotating plate 322 is rotatably connected to a rotating rod 4 through a pin shaft. The outer surface of the rotating rod 4 is rotatably connected to a second rotating plate 41 through a pin shaft. An arc-shaped plate 411 is fixedly connected to the top of the second rotating plate 41. The number of the arc-shaped plates 411 is several. The several arc-shaped plates 411 are arranged in a horizontal array. The side of the second rotating plate 41 away from the rotating rod 4 is rotatably connected to the inner wall of the tank body 1. When the first rotating plate 322 rotates in the present invention, it will drive the rotating rod 4 to move upward synchronously. Since one side of the second rotating plate 41 is rotatably connected to the inner wall of the tank body 1 and the other side is rotatably connected to the rotating rod 4, the first rotating plate 322 will drive several second rotating plates 41 to move synchronously when rotating upward until the second rotating plate 41 is flush with the first rotating plate 322. The several arc-shaped plates 411 fixedly connected to the top of the second rotating plate 41 can make the bottom undercurrent turn back after contacting this position, so that the turned-back undercurrent collides with the flowing undercurrent, and once again reduces the flow kinetic energy of the bottom-restricted undercurrent. The shaking of the bottom of the tank body 1 is reduced, which can play an auxiliary role in reducing the shaking of the whole tank body 1 to a static state subsequently.

[0035] The number of the second rotating plates 41 is several. The several second rotating plates 41 are symmetrically arranged. The bottom of the liquid separation plate 22 located on the left is rotatably connected to a third rotating plate 43 through a pin shaft. A second sealing block 431 is fixedly connected to the top of the third rotating plate 43. The number of the second sealing blocks 431 is two. The two second sealing blocks 431 are symmetrically arranged. A first sealing block 42 is fixedly connected to the top of the first rotating plate 322. The number of the first sealing blocks 42 is two.

[0036] A liquid adding assembly 5 is arranged above the tank body 1. The liquid adding assembly 5 includes a first telescopic cylinder 51. The bottom of the first telescopic cylinder 51 is fixedly connected to the top of the moving block 33 located above. A second connecting pipe 511 is fixedly connected to the top of the first telescopic cylinder 51. A second telescopic cylinder 52 is fixedly connected to the bottom of the second connecting pipe 511. A pressing plate 54 is fixedly connected to the bottom of the second telescopic cylinder 52.

[0037] A one-way valve 541 is fixedly connected to the top of the pressing plate 54. A fuel cylinder 53 is fixedly connected to one side of the top of the tank body 1 close to the filling port 13. The inner wall of the fuel cylinder 53 is in contact with the outer surface of the pressing plate 54. A liquid outlet is formed at the bottom of the fuel cylinder 53, and a discharge pipe 531 is fixedly connected to the bottom of the liquid outlet. The number of the liquid increasing components 5 is two, and the two liquid increasing components 5 are symmetrically arranged. When there is more fuel inside the tank body 1 in the present invention, by connecting an additional fuel pipe to the one-way valve 541, when the tank body shakes, the liquid level of the fuel in the tank will also shake, and the shaking of the liquid level will impact the moving block 33 located above, causing it to move. The movement of the moving block 33 will cause the first telescopic cylinder 51 to transport the fuel inside it to the second telescopic cylinder 52 through the connecting pipe 511. The increase in the fuel in the second telescopic cylinder 52 will cause the pressing plate 54 to push the fuel in the fuel cylinder 53 to be discharged from the discharge pipe 531, and the discharged fuel will enter the tank body 1, and the liquid level height of the fuel inside it will gradually increase. Since the liquid level rises, the free surface of the fuel movement will be reduced, and the reduction of the free surface will reduce the fuel shaking, thereby reducing the overall fuel shaking inside the tank body 1.

[0038] A specific application of this embodiment is as follows: Fuel is filled into the tank body 1 through the feeding port 12, and part of the fuel in the tank body 1 will enter the liquid separation plate 21. When the tank body 1 shakes, the fuel at this part will shake simultaneously, and the shaking fuel will flow along the inner wall of the liquid separation plate 21. At the same time, under the action of the liquid separation column 212, the fuel will be split. The split fuel will flow along the inner walls on both sides of the liquid separation plate 21. The fuel flowing along the left inner wall will change the flow direction in the arc-shaped channel formed by the liquid separation plate 21 and the liquid separation column 212. At the same time, the fuel flowing along the right inner wall of the liquid separation plate 21 will collide with the fuel whose flow direction has changed, causing the fuel at this part to form a vortex at the intersection point, reducing the continuous flow of the fuel. At the same time, the setting of the first liquid separation plate 22 will divide the fuel into the main stream and the tributary. The main stream will move along the outer wall of the liquid separation plate 21, and the tributary will push the moving block 33 and then turn back to collide with the main stream, forming a vortex at the intersection point, and the flow kinetic energy decreases, so that the fuel in the tank can quickly reduce the flow after the tank shakes, reducing the fuel shaking in the tank, and avoiding the problem that the continuous shaking of the fuel affects the subsequent fuel transportation efficiency.

[0039] Due to the sloshing of the fuel inside the tank body 1, the fuel sloshing to the right will come into contact with the first liquid separation plate 22 and flow along the first liquid separation plate 22 at the same time. The flowing fuel will push the moving block 33, and the movement of the moving block 33 will cause the fuel in the first hydraulic cylinder 31 to be input into the second hydraulic cylinder 32 through the first connecting pipe 311, causing the second hydraulic cylinder 32 to extend. The extension of the second hydraulic cylinder 32 will cause the first rotating plate 322 to rotate, making one end of it contact the outer surface of the liquid separation plate 21, forming a compartment below this part and reducing the flow of the bottom undercurrent. Since the number of the separation components 3 is two, compartments will be formed on both the left and right sides of the bottom of the tank body 1. The fuel that cannot flow significantly will enter the liquid separation plate 21, and under the action of the liquid separation plate 21 and the liquid separation column 212, the flow kinetic energy is reduced. The setting of this part can form compartments at the bottom of the tank body, effectively reducing the flow of the bottom undercurrent of the fuel in the tank and playing an auxiliary anti-sloshing effect, enabling the flowing fuel to only enter the liquid separation plate 21 and reducing the sloshing of the fuel. Under the action of the first spring 331, the telescopic block 332 can always fit with the first liquid separation plate 22 and the second liquid separation plate 221. After the moving block 33 moves through the notch 222 and when the fuel becomes slightly sloshing, under the action of the second spring 34, the moving block 33 will be reset, causing the fuel in the second hydraulic cylinder 32 to re-enter the first hydraulic cylinder 31 and causing the first rotating plate 322 to complete the reset.

[0040] While the first rotating plate 322 is rotating, it will drive the rotating rod 4 to move upward synchronously. Since one side of the second rotating plate 41 is rotatably connected to the inner wall of the tank body 1 and the other side is rotatably connected to the rotating rod 4, the first rotating plate 322 will drive a number of second rotating plates 41 to move synchronously while rotating upward until the second rotating plate 41 is level with the first rotating plate 322. A number of arc-shaped plates 411 fixed to the top of the second rotating plate 41 can cause the undercurrent to turn back after contacting this position at the bottom, making the turned-back undercurrent collide with the flowing undercurrent, and reducing the flow kinetic energy of the bottom undercurrent that has been restricted again. The reduction of the sloshing at the bottom of the tank body 1 can play an auxiliary role in reducing the overall sloshing of the subsequent tank body 1 to a standstill. The setting of the first sealing block 42 and the second sealing block 431 can prevent the fuel from passing through the notch opened at this part.

[0041] When there is more fuel inside the fuel tank 1, by connecting an additional fuel pipe to the one-way valve 541, when the fuel tank shakes, the liquid level of the fuel in the tank will also shake. The shaking of the liquid level will impact the moving block 33 located above, causing it to move. The movement of the moving block 33 will cause the first telescopic cylinder 51 to transport the fuel inside it to the second telescopic cylinder 52 through the second connecting pipe 511. The increase in fuel in the second telescopic cylinder 52 will cause the pressing plate 54 to push the fuel in the fuel cylinder 53 out of the discharge pipe 531. The discharged fuel will enter the fuel tank 1 and gradually increase the height of the fuel liquid level inside it. Since the liquid level rises, the free surface of the fuel movement will be reduced. The reduction of the free surface will reduce the fuel shaking, thereby reducing the overall fuel shaking inside the fuel tank 1.
