Description

Technical Field

[0001] This invention relates to the field of methanol storage technology, specifically to a methanol storage and transportation system and method. Background Technology

[0002] Methanol offers several advantages as a clean energy source for ships. First, compared to traditional fuel oil, methanol has significantly lower carbon emissions, aligning with my country's "carbon neutrality and carbon peaking" goals. Second, methanol has a higher flash point than diesel and natural gas, allowing it to evaporate rapidly in air, resulting in a low risk of fire and explosion during storage and use. However, in methanol supply systems, different ships require different storage locations, and situations may necessitate moving storage tanks during operation. Traditional storage tanks are large and heavy, making them difficult for operators to move independently, typically requiring the use of cranes, which is extremely inconvenient.

[0003] To address this issue, Chinese Patent Application Publication No. CN118494985A discloses a marine methanol fuel storage device. Its retractable design allows for the movement of a sliding anti-slip plate, increasing the stability of the tank during use and placement, preventing tipping. Furthermore, the support does not require the tank's own weight to move and transport the tank, saving time and effort and simplifying practical operation. Two relatively distributed protective devices shield the sides of the tank, providing safety protection against impacts during transport or use that could cause rupture and leakage of the methanol fuel.

[0004] However, while moving the tank using only retractable supports and casters improves portability, some larger tanks remain difficult to move. Furthermore, after moving the tank, it's necessary to re-secure it, reconnect the pipeline, and reconnect the tank to the methanol supply system. Moving the tank while it's connected to the pipeline can cause pipeline damage and methanol leaks. Summary of the Invention

[0011] Preferably, the auxiliary control mechanism includes a transmission component and a control component; the connecting frame is driven to the control component via the transmission component; and the control component is driven to the lifting component.

[0012] Preferably, the transmission assembly includes a slider, a second elastic element, and a wedge; the slider is slidably mounted on the base frame and is connected to the control assembly in a transmission manner; the two ends of the second elastic element are respectively connected to the slider and the base frame; the wedge is connected to the slider and abuts against the connecting frame.

[0015] A method for storing and transporting methanol includes the following steps:

[0016] S1. Control the threaded connecting pipe to move downward through the lifting control mechanism to disconnect the threaded connecting pipe from the butt pipe;

[0017] S2. The frame and storage tank are moved by a moving mechanism;

[0018] S3. Disconnect the drive of the moving mechanism to the frame. The moving mechanism controls the threaded connecting pipe to move upward through the lifting control mechanism, connecting the threaded connecting pipe and the butt pipe.

[0019] The advantages of this invention compared to the prior art are:

[0020] 1. This invention achieves automatic tank fixing when the threaded connecting pipe and the connecting pipe are connected through a frame, lifting control mechanism, and moving mechanism. Furthermore, when the connection between the threaded connecting pipe and the connecting pipe is disconnected, the moving mechanism can control the tank's movement.

Furthermore, through the cooperation of the connecting assembly and the auxiliary control mechanism, when the threaded connecting pipe is raised, the auxiliary control mechanism disconnects the connecting assembly, and the rotary drive assembly no longer drives the shaft to rotate. The self-locking structure between the shaft and the wheels prevents the storage tank from moving, thus ensuring stable methanol transmission through the storage tank. When connecting the threaded connecting pipe and the butt-connecting pipe, it avoids situations where pipe breakage or methanol leakage due to storage tank movement.

[0022] 3. This invention achieves the function of controlling the lifting and lowering of the threaded connecting pipe through a base and a lifting assembly. The elastic force provided by the first elastic element on the base gives the threaded connecting pipe a tendency to rise, thus enabling smooth control of the threaded connecting pipe's rise when the connecting assembly disconnects the rotary drive assembly and the rotating shaft. When the connecting assembly disconnects the rotary drive assembly and the rotating shaft, the connecting assembly drives the lifting assembly through an auxiliary control mechanism. The lifting assembly controls the threaded connecting pipe to move upward, ensuring a tight fit between the threaded connecting pipe and the connecting tube. Attached Figure Description

Detailed Implementation

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1-3 A methanol storage and transportation system includes a frame 1 and a main pipeline 5 for transporting methanol. The frame 1 is equipped with a storage tank 11 for storing methanol, and a threaded connecting pipe 111 is movably installed on the storage tank 11. The main pipeline 5 is equipped with a connecting pipe 51 for communicating with the threaded connecting pipe 111. The storage tank 11 is equipped with a lifting control mechanism 2 for controlling the raising and lowering of the threaded connecting pipe 111. The bottom of the frame 1 is equipped with a moving mechanism 3 for controlling the movement of the frame 1. The moving mechanism 3 has a self-locking function. When the moving mechanism 3 disconnects the drive to the frame 1, the lifting control mechanism 2 controls the threaded connecting pipe 111 to rise.

[0036] This invention achieves the function of automatically fixing the storage tank 11 when the threaded connecting pipe 111 is connected to the connecting pipe 51 through a frame 1, a lifting control mechanism 2, and a moving mechanism 3. Furthermore, when the connection between the threaded connecting pipe 111 and the connecting pipe 51 is disconnected, the moving mechanism 3 can control the movement of the storage tank 11. This improves the portability of the storage tank 11 and avoids damage to the pipeline caused by movement when the storage tank 11 is connected to the main pipeline 5, thereby reducing the risk of methanol leakage. It solves the problem that traditional methanol storage tanks 11 are prone to pipeline damage when adjusting their position. The connecting pipe 51 is equipped with a solenoid valve, which automatically closes the connecting pipe 51 after the threaded connecting pipe 111 is separated from the connecting pipe 51. Multiple connecting pipes 51 are provided, spaced apart along the extension direction of the main pipeline 5. The connecting pipes 51 are rotatably mounted on the main pipeline 5, and a rotating seal improves the sealing performance at the interface between the connecting pipe 51 and the main pipeline 5. The main pipe 5 is equipped with a motor for controlling the rotation of the connecting pipe 51. The rotation of the connecting pipe 51 controls the connection and disconnection between the threaded connecting pipe 111 and the connecting pipe 51.

[0037] When moving the storage tank 11, the threaded connecting pipe 111 is first lowered by the lifting control mechanism 2, while the connecting pipe 51 is rotated by the motor on the main pipe 5 until the threaded connecting pipe 111 separates from the connecting pipe 51. At this time, the moving mechanism 3 is activated, controlling the frame 1 to move, and the frame 1 moves the storage tank 11 synchronously. After the storage tank 11 moves to the designated position, the driving of the moving mechanism 3 is stopped, and the threaded connecting pipe 111 is then raised by the lifting control mechanism 2, while the connecting pipe 51 is rotated by the motor on the main pipe 5, so that the threaded connecting pipe 111 can be tightly connected to the connecting pipe 51 after contacting it. After the threaded connecting pipe 111 is raised, the moving mechanism 3 disconnects its drive to the frame 1, preventing the moving mechanism 3 from controlling the frame 1 to move. At this time, the position of the frame 1 is fixed only by the self-locking performance of the moving mechanism 3, maintaining the stability of the storage tank 11's position. To prevent damage to the pipeline and methanol leakage caused by the movement of the storage tank 11 when the threaded connecting pipe 111 is connected to the connecting pipe 51.

[0038] Reference Figure 1 and Figure 5 The moving mechanism 3 includes a base frame 31, a rotary drive assembly 32, and a connecting assembly 33. The base frame 31 is located at the bottom of the frame 1, and a wheel 311 and a rotating shaft 312 are rotatably mounted on the base frame 31. The rotating shaft 312 is connected to the wheel 311 in a transmission manner. The rotary drive assembly 32 is mounted on the base frame 31. The rotary drive assembly 32 is connected to the rotating shaft 312 in a transmission manner through the connecting assembly 33. The frame 1 is provided with an auxiliary control mechanism 4 for driving the lifting control mechanism 2. The auxiliary control mechanism 4 is connected to the connecting assembly 33 in a transmission manner.

[0039] This invention achieves the function of controlling the movement of the storage tank 11 through the base frame 31, the rotary drive assembly 32, the connecting assembly 33, and the auxiliary control mechanism 4. Through the cooperation of the connecting assembly 33 and the auxiliary control mechanism 4, the connecting assembly 33 disconnects the rotary drive assembly 32 from the rotating shaft 312, and the rotary drive assembly 32 no longer drives the rotating shaft 312 to rotate. When the auxiliary control mechanism 4 drives the lifting control mechanism 2, the lifting control mechanism 2 drives the threaded connecting pipe 111 to move upwards. The self-locking structure between the rotating shaft 312 and the wheel 311 prevents the storage tank 11 from moving, ensuring stable methanol transmission through the storage tank 11. When the threaded connecting pipe 111 and the connecting pipe 51 are connected, it prevents pipe breakage and methanol leakage caused by the movement of the storage tank 11. The frame 1 is equipped with a controller for human-machine interaction, and the rotary drive assembly 32 is electrically connected to the controller. The rotating shaft 312 is connected to the wheel 311 via a worm gear structure. The self-locking performance of the worm gear allows the frame 1 to be fixed in position when the connecting assembly 33 is disconnected. The speed of wheel 311 can be reduced by using the worm gear reduction transmission, thereby improving the movement stability of storage tank 11.

[0040] In operation, the operator connects the rotary drive assembly 32 and the rotating shaft 312 via the connecting assembly 33. Simultaneously, the connecting assembly 33 drives the lifting control mechanism 2 via the auxiliary control mechanism 4. The lifting control mechanism 2 controls the threaded connecting pipe 111 to move downwards, separating it from the connecting pipe 51. At this time, the controller sends a signal to the rotary drive assembly 32. Upon receiving the signal, the rotary drive assembly 32 drives the rotating shaft 312 to rotate via the connecting assembly 33. The rotating shaft 312 transmits torque to the wheels 311, controlling their rotation, which in turn propels the frame 1 to move. After the storage tank 11 moves to the designated position, the connecting assembly 33 disconnects the rotary drive assembly 32 from the rotating shaft 312. Simultaneously, the connecting assembly 33 drives the lifting control mechanism 2 via the auxiliary control mechanism 4. The lifting control mechanism 2 controls the threaded connecting pipe 111 to move upwards, connecting it to the connecting pipe 51.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The lifting control mechanism 2 includes a base 21 and a lifting assembly 22. The base 21 is set on the outer wall of the storage tank 11. A first elastic element 211 is provided on the base 21. The two ends of the first elastic element 211 are respectively connected to the base 21 and the threaded connecting pipe 111. The lifting assembly 22 is set on the base 21. The auxiliary control mechanism 4 is connected to the threaded connecting pipe 111 through the lifting assembly 22.

[0042] This invention achieves the function of controlling the lifting and lowering of the threaded connecting pipe 111 through the base 21 and the lifting assembly 22. The elastic force provided by the first elastic element 211 on the base 21 causes the threaded connecting pipe 111 to have a tendency to rise, thus enabling smooth control of the threaded connecting pipe 111's rise when the connecting assembly 33 disconnects the rotary drive assembly 32 and the rotating shaft 312. When the connecting assembly 33 disconnects the rotary drive assembly 32 and the rotating shaft 312, the connecting assembly 33 drives the lifting assembly 22 through the auxiliary control mechanism 4. The lifting assembly 22 controls the threaded connecting pipe 111 to move upward, allowing the threaded connecting pipe 111 to fit tightly with the connecting pipe 51. When the connecting assembly 33 connects the rotary drive assembly 32 and the rotating shaft 312, the connecting assembly 33 drives the lifting assembly 22 through the auxiliary control mechanism 4. The lifting assembly 22 controls the threaded connecting pipe 111 to move downward, separating the threaded connecting pipe 111 from the connecting pipe 51. Then, the rotary drive assembly 32 drives the rotating shaft 312 to rotate through the connecting assembly 33, moving the storage tank 11.

[0043] Reference Figure 1 , Figure 3 and Figure 4 The lifting assembly 22 includes a movable frame 221, a support 222, and a bracket 223. The movable frame 221 is rotatably mounted on the base 21 and has a first straight groove 2211. The support 222 is mounted on the threaded connecting pipe 111 and has a second fixed shaft 2221 that slides with the first straight groove 2211. The bracket 223 is slidably mounted on the base 21 and has a second straight groove 2231. The movable frame 221 has a first fixed shaft 2212 that slides with the second straight groove 2231.

[0044] This invention achieves the function of controlling the lifting and lowering of the threaded connecting pipe 111 through the movable frame 221, the support 222, and the bracket 223. The bracket 223 is connected to the auxiliary control mechanism 4. When the connecting assembly 33 disconnects the rotation drive assembly 32 and the rotating shaft 312, the connecting assembly 33 controls the bracket 223 to move closer to the threaded connecting pipe 111 through the auxiliary control mechanism 4. The bracket 223 pushes the first fixed shaft 2212 on the movable frame 221 through the groove wall of the second straight groove 2231, thereby pushing the movable frame 221 to rotate. The movable frame 221 pushes the second fixed shaft 2221 through the groove wall of the first straight groove 2211, and the second fixed shaft 2221 drives the support 222 and the threaded connecting pipe 111 to move, thereby controlling the threaded connecting pipe 111 to move upward.

[0045] Reference Figures 5-8The connecting assembly 33 includes a connecting ring 331, a docking ring 332, a connecting frame 333, and a linear actuator 334. The connecting ring 331 is rotatably mounted on the base frame 31 and is connected to the rotary drive assembly 32. The docking ring 332 is axially slidably sleeved on the rotating shaft 312. When the connecting ring 331 abuts against the docking ring 332, it drives the docking ring 332 to rotate synchronously. The connecting frame 333 is rotatably connected to the docking ring 332. The linear actuator 334 is mounted on the base frame 31 and is used to drive the connecting frame 333 to move.

[0046] This invention achieves the function of controlling the transmission connection between the rotary drive assembly 32 and the rotating shaft 312 through a connecting ring 331, a docking ring 332, a connecting frame 333, and a linear actuator 334. The linear actuator 334 is preferably a linear cylinder or an electric push rod, and is electrically connected to the controller. The connecting ring 331 is provided with a docking post 3311 and a third elastic element 3312. The docking post 3311 is slidably mounted on the connecting ring 331, and the two ends of the third elastic element 3312 are respectively connected to the docking post 3311 and the connecting ring 331. The docking ring 332 has a docking groove 3321 that mates with the docking post 3311. In operation, the operator sends a signal to the linear actuator 334 through the controller. Upon receiving the signal, the linear actuator 334 drives the connecting frame 333 to move closer to the connecting ring 331, which in turn drives the docking ring 332 to move, causing the docking ring 332 to abut against the connecting ring 331. The rotary drive assembly 32 drives the connecting ring 331 to rotate, and the connecting ring 331 drives the docking post 3311 to rotate. When the docking post 3311 is aligned with the docking groove 3321, the docking post 3311 engages with the docking groove 3321 under the elastic force of the third elastic element 3312. The connecting ring 331 drives the docking ring 332 to rotate through the engagement of the docking post 3311 and the docking groove 3321. The docking ring 332 drives the rotating shaft 312 to rotate, and then transmits torque to the wheel 311 through the rotating shaft 312. The rotation of the wheel 311 controls the movement of the frame 1 and the storage tank 11.

[0047] Reference Figure 1 and Figure 5 The auxiliary control mechanism 4 includes a transmission component 41 and a control component 42; the connecting frame 333 is connected to the control component 42 via the transmission component 41; the control component 42 is connected to the lifting component 22 via the transmission component 41.

[0048] This invention achieves the function of transmitting the torque provided by the connecting component 33 to the lifting component 22 through the transmission component 41 and the control component 42, thereby activating the linear drive component and controlling the lifting of the threaded connecting pipe 111. When the connecting component 33 disconnects the connection between the rotary drive component 32 and the rotating shaft 312, the linear actuator 334 controls the connecting frame 333 to move, and the connecting frame 333 drives the docking ring 332 to move, causing the docking ring 332 to separate from the connecting ring 331. At the same time, the connecting frame 333 drives the control component 42 through the transmission component 41, and the control component 42 transmits the torque to the bracket 223, causing the bracket 223 to move. The bracket 223 pushes the first fixed shaft 2212 on the movable frame 221 through the groove wall of the second straight groove 2231, thereby pushing the movable frame 221 to rotate. The movable frame 221 pushes the second fixed shaft 2221 through the groove wall of the first straight groove 2211, and the second fixed shaft 2221 drives the support 222 and the threaded connecting pipe 111 to move, controlling the threaded connecting pipe 111 to move upward.

[0049] Reference Figure 5 , Figure 9 and Figure 10 The transmission assembly 41 includes a slider 411, a second elastic element 412, and a wedge 413. The slider 411 is slidably mounted on the base frame 31 and is connected to the control assembly 42 in a transmission manner. The two ends of the second elastic element 412 are connected to the slider 411 and the base frame 31, respectively. The wedge 413 is connected to the slider 411 and abuts against the connecting frame 333.

[0050] This invention utilizes a slider 411, a second elastic element 412, and a wedge 413 to transmit the torque provided by the linear actuator 334 to the control component 42. When the linear actuator 334 controls the connecting frame 333 to move, the connecting frame 333 drives the docking ring 332 to move, causing the docking ring 332 to separate from the connecting ring 331. Simultaneously, the connecting frame 333 presses against the wedge 413, causing the wedge 413 to move under the pressure, which in turn drives the slider 411 to move. The second elastic element 412 contracts under pressure, and the slider 411 transmits torque to the control component 42 during its movement.

[0051] Reference Figure 5 , Figure 9 and Figure 10 The control component 42 includes a hinge seat 421, a transmission rod 422, and a slide rod 423. The hinge seat 421 is disposed on the outer wall of the storage tank 11. The transmission rod 422 is rotatably disposed on the hinge seat 421, and a third straight groove 4221 is provided on the transmission rod 422. The slide block 411 is provided with a long shaft 4111 that slides in cooperation with the third straight groove 4221. The slide rod 423 is hinged to the transmission rod 422, and the slide rod 423 is connected to the lifting control mechanism 2 in a transmission manner.

[0052] This invention achieves the function of transmitting torque to the lifting assembly 22 through the hinge seat 421, transmission rod 422, and slide rod 423. The slide rod 423 is connected to the bracket 223. After the linear actuator 334 is activated, it drives the connecting frame 333 to move. The connecting frame 333 pushes the slider 411 to move via the wedge block 413, and the slider 411 drives the long shaft 4111 to move. The long shaft 4111 pushes the transmission rod 422 to rotate around the hinge seat 421, the transmission rod 422 pulls the slide rod 423, and the slide rod 423 drives the bracket 223 to move, thereby controlling the lifting and lowering of the threaded connecting pipe 111.

[0053] Reference Figure 1 , Figure 5 and Figure 6 The rotary drive assembly 32 includes a rotary driver 321, a first pulley 322, a second pulley 323, and a drive belt 324. The rotary driver 321 is mounted on a base frame 31. The first pulley 322 is rotatably mounted on the base frame 31, and the second pulley 323 is sleeved on the drive end of the rotary driver 321. The drive belt 324 connects the first pulley 322 and the second pulley 323.

[0054] This invention achieves the function of driving the rotating shaft 312 to rotate through a rotary driver 321, a first pulley 322, a second pulley 323, and a transmission belt 324. The first pulley 322 is coaxially connected to the connecting ring 331. The rotary driver 321 is preferably a servo motor and is electrically connected to a controller. In operation, the controller sends a signal to the rotary driver 321. Upon receiving the signal, the rotary driver 321 drives the first pulley 322 to rotate via the second pulley 323 and the transmission belt 324. The first pulley 322 then drives the connecting ring 331 to rotate. When the connecting ring 331 abuts against the mating ring 332, the connecting ring 331 drives the mating ring 332 to rotate synchronously. The mating ring 332 then drives the rotating shaft 312 to rotate, which in turn drives the wheel 311 to rotate.
