Description

Technical Field

[0001] This utility model relates to the field of ship fuel consumption monitoring, specifically a fixed platform for fuel consumption monitoring equipment suitable for Coriolis flow meters 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. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model provides a kind of oil consumption monitoring equipment fixed platform suitable for ship end Coriolis force flowmeter 14, Coriolis force flowmeter 14 can be U type, can also be straight pipe type.As shown in the figure, the fixed platform includes: horizontal inlet pipe 1, horizontal outlet pipe 2, bottom plate 8, shock pad 10, inlet support frame 11 and outlet support frame 12. Figure 1 Among them, the horizontal inlet pipe 1 outlet end is connected with one end of Coriolis force flowmeter 14, the inlet end of horizontal outlet pipe 2 is connected with the other end of Coriolis force flowmeter 14, and the horizontal inlet pipe 1, the horizontal outlet pipe 2 and the measuring tube of Coriolis force flowmeter 14 are coaxial and stationary, which can ensure the accurate measurement of flowmeter 14.As shown in the figure, the bottom plate 8 is fixed with the deck 15 of the ship, and the shock pad 10 is clamped between the bottom plate 8 and the deck 15 and contacts both of them. Figure 1 When the main engine or the ship vibrates, the shock pad 10 can deform to absorb vibration, and the shock pad 10 can be a silica gel pad. The bottom of the inlet support frame 11 is fixed with the bottom plate 8, and the top end is fixed with a pipe clamp 13 sleeved outside the horizontal inlet pipe 1, and the bottom of the pipe clamp 13 is provided with a pipe clamp support 131, and the pipe clamp 13 is fixed with the inlet support frame 11 through the pipe clamp support 131. The bottom of the outlet support frame 12 is fixed with the bottom plate 8, and the top end is fixed with a pipe clamp 13 sleeved outside the horizontal inlet pipe 1, and the pipe clamp 13 is the same structure as the pipe clamp 13 of the inlet support frame 11. The inlet support frame 11 and the outlet support frame 12 support the horizontal inlet pipe 1 and the horizontal outlet pipe 2 respectively, and the vibration of the main engine or the ship is blocked by the shock pad 10 and the support frame to the horizontal inlet pipe 1 and the horizontal outlet pipe 2, thereby improving the measurement accuracy of Coriolis force flowmeter 14.

[0023] In this embodiment, the bottom plate 8 is fixed between the main engine or the deck 15 by the bolt 9, the bolt 9 is fixed with the deck 15 after passing through the bottom plate 8 and the shock pad 10, and the shock pad 10 is deformed by a certain amount when pressed under the bottom plate 8, but there is still a deformation allowance. The horizontal inlet pipe 1 and the horizontal outlet pipe 2 are connected with the flowmeter 14 through the connecting flange 7.

[0024] As shown in the figure, Figure 1As shown, the fixed platform also includes an external fuel inlet pipe 3, an external fuel outlet pipe 4, an inlet hose 5, and an outlet hose 6. One end of the inlet hose 5 is connected to the outlet end of the external fuel inlet pipe 3, and the other end is connected to the inlet end of the horizontal fuel inlet pipe 1. One end of the outlet hose 6 is connected to the outlet end of the horizontal fuel outlet pipe 2, and the other end is connected to the inlet end of the external fuel outlet pipe 4. The inlet hose 5 has a nut flange 16, which is connected to the connecting flange 7 of the external fuel inlet pipe 3 and the horizontal fuel inlet pipe 1. The outlet hose 6 also has a nut flange 16, which is connected to the connecting flange 7 of the external fuel outlet pipe 4 and the horizontal fuel outlet pipe 2.

Since the vibrations of the external oil inlet pipe 3 and the external oil outlet pipe 4 are absorbed by the oil inlet hose 5 and the oil outlet hose 6 respectively, the vibrations of the external oil inlet pipe 3 and the external oil outlet pipe 4 will not be transmitted to the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2. In this embodiment, the external oil inlet pipe 3, the external oil outlet pipe 4, the horizontal oil inlet pipe 1 and the horizontal oil outlet pipe 2 are all steel pipes, and the hoses can be rubber hoses.

Both include main supports 111 and 121 and multiple auxiliary supports 112 and 122. The main supports 111 and 121 are vertical columns. One end of the main supports 111 and 121 is fixed to the base plate 8, and the other end is provided with the oil inlet connection flange 7 or the oil outlet connection flange 7. Multiple auxiliary supports 112 and 122 are arranged around the main supports 111 and 121. In this embodiment, there are four auxiliary supports 112 and 122 arranged around the main supports 111 and 121. The auxiliary supports 112 and 122 are evenly arranged around the main supports. Each auxiliary support includes a vertical section 1121 and 1221 and an inclined section 1112 and 1222 integral with the vertical section 1122 and 1222. One end of the vertical section 1121 and 1221 is fixed to the base plate 8, and one end of the inclined section 1112 and 1222 is fixed to the side wall of the main support 111 and 121. The inclined section 1112 and 1222 is fixedly connected to the main support 111 and 121 at half the height of the main support. The auxiliary supports 112 and 122 can reduce or avoid the main support 111 and 121 from swaying in the horizontal direction, making the main support 111 and 121 more stable, thereby further improving the measurement accuracy of the Coriolis flowmeter 14.

[0026] The main and auxiliary supports can be made of stainless steel pipes or columns.

[0027] The above examples are only exemplary embodiments of the present application, and are not used to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications or equivalent replacements made by those skilled in the art to the present application within the spirit and protection scope of the present application also fall within the protection scope of the present application.
