Description

Technical Field

[0001] This invention relates to the field of ship fuel consumption monitoring, specifically to a shock-absorbing platform suitable for a Coriolis flow meter at the ship's end. Background Technology

[0002] Fuel consumption of ship equipment is a key concern for shipping companies, as it represents a critical cost throughout the voyage. However, accurately and consistently monitoring fuel consumption, especially the main engine's fuel consumption, remains a significant technical challenge that the industry has yet to fully address. Shipboard equipment, particularly main engine and auxiliary machinery, primarily uses high-viscosity particulate liquids as fuel. Commonly used shipboard flow meters include volumetric flow meters, turbine flow meters, and mass flow meters. Volumetric flow meters offer high accuracy and are suitable for high-viscosity fluids, but their density is significantly affected by temperature, making them unsuitable for mass measurement. Turbine flow meters provide accurate measurements but are not suitable for high-viscosity particulate fluids. Mass flow meters accurately measure liquid mass, but their Coriolis effect-based design makes them susceptible to vibrations from the ship's main engine and piping, leading to data fluctuations.

[0003] In existing designs, flow meters at the ship's end are directly installed on steel pipes, which are in direct contact with the deck or main engine equipment. This results in vibrations generated during main engine operation and ship navigation being directly transmitted to the flow meters, causing significant interference to Coriolis flow meters that measure flow based on vibration principles.

[0037] The application provides a shock absorbing platform suitable for a ship end Coriolis force flowmeter 9, as shown in Figure 1 and Figure 2As shown, it comprises a horizontal oil inlet pipe 1, a horizontal oil outlet pipe 2, a frame 3 and two dampers 4. The oil outlet end of the horizontal oil inlet pipe 1 is connected with one end of the Coriolis flowmeter 9, the oil inlet end of the horizontal oil outlet pipe 2 is connected with the other end of the Coriolis flowmeter 9. The Coriolis flowmeter 9 can be a U-shaped one or a straight pipe type one. The horizontal oil inlet pipe 1, the horizontal oil outlet pipe 2 and the measuring pipe of the Coriolis flowmeter 9 are coaxial. The frame 3 is fixed with the deck main engine of the ship. The frame 3 can be made of stainless steel. The two dampers 4 are installed on the frame 3. One of the dampers 4 is sleeved on the outside of the horizontal oil inlet pipe 1 to support and damp the horizontal oil inlet pipe 1. The other damper 4 is sleeved on the outside of the horizontal oil outlet pipe 2 to support and damp the horizontal oil outlet pipe 2. Figure 3 As shown, the damper 4 comprises a first damping member 41 connected with the horizontal oil inlet pipe 1 or the horizontal oil outlet pipe 2 and rotatable relative to the horizontal oil inlet pipe 1 or the horizontal oil outlet pipe 2, and a second damping member 42 connected with the frame 3 and rotatable relative to the frame 3. The second damping member 42 is connected with the first damping member 41 and rotatable relative to the first damping member 41. The second damping member 42 is provided with a damping rod 421 and a rod sleeve 422. One end of the damping rod 421 extends into the rod sleeve 422 and is movable along the axis of the rod sleeve 422. The damping rod 421 is provided with a damping rod limiting structure 423. The rod sleeve 422 is provided with a rod sleeve limiting structure 424 which can cooperate with the damping rod limiting structure 423 to prevent the damping rod 421 from coming out of the rod sleeve 422. In this embodiment, the rod sleeve limiting structure 424 is a cover fixed on the end of the rod sleeve 422. The cover has a hole allowing the damping rod 421 to pass through. The damping rod 421 is sleeved with a spring 425. The spring 425 is compressed when the damping rod 421 moves into the rod sleeve 422.

[0038] When the frame 3 vibrates, the spring 425 can absorb the vibration along the axial direction of the damping rod 421 and prevent the vibration from being transmitted to the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2. At the same time, the second damping member 42 can rotate relative to the frame 3 and the first damping member 41 to offset part of the vibration in the direction perpendicular to the damping rod 421. The vibration is transmitted to the first damping member 41 which can also rotate relative to the horizontal oil inlet pipe 1 or the horizontal oil outlet pipe 2. In this way, through multi-directional and multi-stage damping, the vibration transmitted to the horizontal oil inlet pipe 1, the horizontal oil outlet pipe 2 and the Coriolis flowmeter 9 is greatly reduced, and the measurement accuracy of the Coriolis flowmeter 9 can be greatly improved.

[0039] In this embodiment, the outer wall of the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2 is provided with a steel pipe screw 11 which can be made of stainless steel and can be integrally formed with the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2 or can be fixedly connected through interference. Figure 3As shown, one end of the steel pipe screw rod 11 has a ring-shaped screw head 111 perpendicular to its axis, and a center bearing 411 and a center fixing nut 112 are mounted outside the steel pipe screw rod 11. The inner ring of the center bearing 411 is fixed with the steel pipe screw rod 11, and the outer ring of the center bearing 411 can rotate relative to the steel pipe screw rod 11. The center fixing nut 112 is connected with the steel pipe screw rod 11 through threads, and the center fixing nut 112 and the screw head 111 are respectively located on the two sides of the center bearing 411 to limit the center bearing 411 axially.

[0040] As Figure 1 shown, in the present embodiment, the frame 3 has vertical arms 32 and horizontal arms 31, two vertical arms 32 and one horizontal arm 31 of which are used to mount the shock absorbers 4 of the horizontal oil inlet pipe 1, and the other two vertical arms 32 and the other horizontal arm 31 are used to mount the shock absorbers 4 of the horizontal oil outlet pipe 2. The shock absorbers 4 are provided with three second shock absorbing members 42, which surround the lower half of the steel pipe screw rod 11 and are located in the same plane in the state that the frame 3 is stationary, i.e., in the plane perpendicular to the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2 in the present embodiment. The included angle between two adjacent second shock absorbing members 42 is 90°, and the middle second shock absorbing member 42 is vertical and connected with the horizontal arm 31 of the frame 3, and the other two second shock absorbing members 42 are respectively connected with the two vertical arms 32. The shock absorbing rods 421 and springs 425 of the vertical second shock absorbing members 42 are used to reduce the vertical vibration, and the shock absorbing rods 421 and springs 425 of the other two second shock absorbing members 42 are used to reduce the horizontal vibration, and the mutual rotation among the first shock absorbing members 41, the second shock absorbing members 42 and the frame 3 also reduces the vibration.

[0041] In Figure 4 the present embodiment, the center fixing nut 112 is removed, as Figure 4 shown, the outer wall of the center bearing 411 is provided with three connecting blocks 412, each of which is fixed with a transfer bearing 413, and the diameter of the transfer bearing 413 is smaller than that of the center bearing 411. Each second shock absorbing member 42 further includes a rotating pin 427 penetrating through the transfer bearing 413 and fixed with the inner ring of the transfer bearing 413, and the two ends of the rotating pin 427 are exposed. The rotating pins 427 of the three second shock absorbing members 42 correspond to the three transfer bearings 413 one by one, and the second shock absorbing member 42 further includes a connecting frame 426 fixedly connected with the other end of the shock absorbing rod 421, and the connecting frame 426 is fixedly connected with the two ends of the rotating pin 427. In the present embodiment, the spring 425 is located between the rod sleeve limiting structure 424 and the connecting frame 426. The transfer bearing 413 makes the relative rotation between the first shock absorbing member 41 and the second shock absorbing member 42 more smooth, preventing the rotation from being affected by the buffering of the vibration.

[0042] AsFigure 5 As shown, the connecting frame 426 includes two parallel first sidewalls 4261, each with a threaded hole. The rotating pin 427 is a double-ended screw, with both ends of the double-ended screw fixed to the two first sidewalls 4261 respectively via threads. The connecting frame 426 also includes a second sidewall 4262 connecting the two first sidewalls 4261, and the shock-absorbing rod 421 is fixedly connected to the second sidewall 4262.

[0043] like Figure 5 As shown, the second damping component 42 further includes a rod sleeve bearing 428 located at the other end of the rod sleeve 422. The outer wall of the rod sleeve bearing 428 is fixedly connected to the other end of the rod sleeve 422. The damper 4 also includes a fixing pin 33 that passes through the rod sleeve bearing 428 and is fixed to the inner ring of the rod sleeve bearing 428. The fixing pin 33 is fixed to the frame 3. The rotation of the second damping component 42 relative to the frame 3 is achieved through the rod sleeve bearing 428. In this embodiment, the fixing pin 33 is a fixing screw. One end of the fixing screw is equipped with a nut 34 to limit the rod sleeve bearing 428, and the other end passes through the rod sleeve bearing 428 and is fixed to the frame 3.

[0044] like Figure 1 and Figure 2 As shown, the shock absorption platform also includes an external oil inlet pipe 5, an external oil outlet pipe 6, an inlet hose 7, and an outlet hose 8. One end of the inlet hose 7 is connected to the outlet end of the external oil inlet pipe 5, and the other end is connected to the inlet end of the horizontal oil inlet pipe 1. One end of the outlet hose 8 is connected to the outlet end of the horizontal oil outlet pipe 2, and the other end is connected to the inlet end of the external oil outlet pipe 6. In this embodiment, both ends of the inlet hose 7 and the outlet hose 8 are provided with nut flanges 71, which are connected to the connecting flanges 12 of the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2 through the nut flanges 71. The inlet hose 7 and the outlet hose 8 absorb the vibration of the external oil inlet pipe 5 and the external oil outlet pipe 6 respectively. Therefore, the vibration of the external oil inlet pipe 5 and the external oil outlet pipe 6 will not be transmitted to the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2, thereby further improving the measurement accuracy of the Coriolis flow meter 9.

The scope of protection of the present invention is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art to the present invention within its spirit and scope of protection also fall within the scope of protection of the present invention.
