Description

Technical Field

[0001] The invention relates to the technical field of ballast water discharge flow monitoring, in particular to ballast water accident discharge flow monitoring equipment. Background Art

[0002] Ballast water refers to water and suspended matter added to a ship to control the ship's heel, trim, draft, stability or stress. Its main function is to maintain stability when the ship is unloaded and enhance its ability to resist wind and waves. When the ship needs to load cargo, the ballast water can be discharged to adjust the ship's buoyancy and center of gravity. If the ballast water is not discharged, accidents are prone to occur.

[0003] At present, when discharging ballast water, ships need to use corresponding monitoring equipment to monitor the discharge amount of ballast water, so as to grasp the remaining amount of ballast water inside the ship in real time. The commonly used monitoring equipment in the prior art is mainly flow meters and other related products. However, when ballast water is discharged, especially at the moment when the discharge valve is opened, the ballast water pressure inside the ship is particularly large. Under the instantaneous pressure, the existing monitoring equipment will be subjected to a particularly large impact, and long-term use will cause damage to the monitoring equipment. Summary of the invention

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example:

[0026] like Figure 1-5As shown, an embodiment of the present invention provides a ballast water accident discharge flow monitoring device, including a telescopic inner tube 1 and a fixed outer tube 2. The arrangement of the telescopic inner tube 1 and the fixed outer tube 2 facilitates the expansion and contraction of the metering chamber. When the ballast water discharge valve is opened, the impact force of the ballast water is buffered under the action of the spring 10, which can effectively buffer the flow monitoring component inside the telescopic inner tube 1, which is beneficial to improving the service life of the monitoring equipment. The right side of the fixed outer tube 2 is a water inlet, and a sliding cavity 3 is arranged inside the fixed outer tube 2. A sliding hole 4 is arranged on the left side wall of the fixed outer tube 2, and the telescopic inner tube 1 is slidably connected to the inside of the sliding hole 4. The arrangement of the sliding hole 4 facilitates the telescopic inner tube 1 to slide on the fixed outer tube 2. One end of the telescopic inner tube 1 located inside the sliding cavity 3 is fixedly connected to a piston ring 5, and the piston ring 5 is slidably connected to the inner wall of the sliding cavity 3. The arrangement of the piston ring 5 is mainly used to achieve a sealing effect to prevent leakage of the telescopic inner tube 1 and the fixed outer tube 2 during the sliding process. , an extension groove 7 is provided on the left side wall of the piston ring 5. The setting of the extension groove 7 facilitates the movement of the extrusion ring 9 after being squeezed by the spring 10. When the extrusion ring 9 moves under the squeeze of the spring 10, it will squeeze the sealing ring 8, thereby improving the sealing between the sealing ring 8 and the piston ring 5, avoiding the ballast water pressure from being too high and causing the ballast water to leak from the piston ring 5, and ensuring the sealing of the monitoring equipment. An extrusion ring 9 is slidably connected to the circumferential surface of the telescopic inner tube 1. The extrusion ring 9 mainly cooperates with the spring 10 after squeezing to squeeze the sealing ring 8. The spring 10 is fixedly connected to the left side wall of the extrusion ring 9. The spring 10 also has the function of restoring the telescopic inner tube 1 and the fixed outer tube 2 to the initial state. The left side wall of the spring 10 is fixedly connected to the left side wall of the sliding cavity 3, and the spring 10 is sleeved on the telescopic inner tube 1. The left side wall of the piston ring 5 is also fixedly connected to the sealing ring 8, and the sealing ring 8 is located on the outside of the extension groove 7, and the sealing ring 8 fits the inner wall of the sliding cavity 3;

[0027] A flow monitoring component is arranged inside the telescopic inner tube 1, and the flow monitoring component is essentially a turbine flowmeter. A display meter 16 is fixedly connected to the circumferential surface of the telescopic inner tube 1, and the display meter 16 is located on the left side of the fixed outer tube 2. The display meter 16 is used in conjunction with the flow monitoring component.

[0028] The left end of the telescopic inner tube 1 is fixedly connected with a first connecting flange 11, and the right end of the fixed outer tube 2 is fixedly connected with a second connecting flange 12. A plurality of mounting holes 13 are arranged inside the first connecting flange 11 and the second connecting flange 12, and the plurality of mounting holes 13 are arranged in a circular array. The arrangement of the first connecting flange 11, the second connecting flange 12, and the mounting holes 13 facilitates the installation of the telescopic inner tube 1 and the fixed outer tube 2. The side walls of the first connecting flange 11 and the second connecting flange 12 are both provided with mounting grooves 14, and the interior of the mounting grooves 14 is fixedly connected with a sealing gasket 15. The arrangement of the sealing gasket 15 is mainly used to improve the sealing performance when the first connecting flange 11 and the second connecting flange 12 are connected. A telescopic rod 17 is fixedly connected between the first connecting flange 11 and the second connecting flange 12. There are two telescopic rods 17, and they are symmetrically arranged on the front and rear sides of the telescopic inner tube 1 and the fixed outer tube 2. The arrangement of the telescopic rod 17 mainly limits the telescopic inner tube 1 and the fixed outer tube 2 to prevent the telescopic inner tube 1 and the fixed outer tube 2 from rotating relative to each other.

[0029] A limiting ring 6 is fixedly connected to the inner wall of the sliding cavity 3, and the limiting ring 6 is located on the right side of the piston ring 5. The setting of the limiting ring 6 is mainly to limit and block the piston ring 5. The inner wall of the sealing ring 8 is an inclined surface, and the outer wall of the extrusion ring 9 is an inclined surface, and the extrusion ring 9 is used in conjunction with the sealing ring 8. The extrusion ring 9 is arranged corresponding to the extension groove 7. Inclined surfaces are arranged on the sealing ring 8 and the extrusion ring 9, which facilitates the extrusion ring 9 to extrude the sealing ring 8 and improve the sealing performance of the piston ring 5. The materials in this application are all made of corrosion-resistant materials.

[0030] Working principle: When in use, first install the telescopic inner tube 1 and the fixed outer tube 2 through the first connecting flange 11, the second connecting flange 12, the mounting hole 13, and the fastening bolts. The drain pipe installed on the left side of the first connecting flange 11 is movable and cannot be fixed. After the installation is completed, the ballast water discharge valve is opened, and the impact force of the ballast water impacts the telescopic inner tube 1. At the same time, the spring 10 begins to compress, and the reaction force of the spring 10 is used to squeeze the extrusion ring 9, and the extrusion ring 9 gradually enters the extension groove 7. At the same time, the extrusion ring 9 squeezes the sealing ring 8, which improves the sealing between the sealing ring 8 and the piston ring 5, and avoids the ballast water pressure being too high to cause the ballast water to leak from the piston ring 5. In addition, the telescopic inner tube 1 and the fixed outer tube 2 slide relative to each other while cooperating with the spring 10 for buffering to avoid damage to the flow monitoring components inside the telescopic inner tube 1.
