Description

Technical Field

[0001] This invention relates to the field of ballast water discharge flow monitoring technology, specifically to ballast water accident discharge flow monitoring equipment. Background Technology

[0002] Ballast water refers to the water and suspended matter added to a ship to control its list, trim, draft, stability, or stress. Its main function is to maintain stability when the ship is unloaded and enhance its resistance to wind and waves. When a ship needs to be loaded with cargo, the ballast water can be discharged to adjust the ship's buoyancy and center of gravity. Failure to discharge ballast water can easily lead to accidents.

[0003] Currently, ships need to use corresponding monitoring equipment to monitor the amount of ballast water discharged when discharging ballast water, so as to make it easy to know the remaining amount of ballast water inside the ship in real time. The commonly used monitoring equipment in the existing technology is mainly flow meter and related products. However, when ballast water is discharged, especially at the moment the discharge valve is opened, the pressure of ballast water inside the ship is particularly high. Under the instantaneous pressure, the existing monitoring equipment will be subjected to a particularly large impact, which will cause damage to the monitoring equipment in the long run. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a ballast water accident discharge flow monitoring device, which solves the problem that existing monitoring devices are easily damaged by the instantaneous pressure of ballast water discharge when monitoring the discharge volume.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a ballast water accident discharge flow monitoring device, comprising a telescopic inner tube and a fixed outer tube, wherein the right side of the fixed outer tube is an inlet, a sliding cavity is provided inside the fixed outer tube, a sliding hole is provided on the left side wall of the fixed outer tube, and the telescopic inner tube is slidably connected inside the sliding hole, a piston ring is fixedly connected to one end of the telescopic inner tube inside the sliding cavity, and the piston ring is slidably connected to the inner wall of the sliding cavity, an extension groove is provided on the left side wall of the piston ring, a compression ring is slidably connected to the circumferential surface of the telescopic inner tube, a spring is fixedly connected to the left side wall of the compression ring, the left side wall of the spring is fixedly connected to the left side wall of the sliding cavity, and the spring is sleeved on the telescopic inner tube, and a sealing ring is also fixedly connected to the left side wall of the piston ring, and the sealing ring is located outside the extension groove, and the sealing ring is in contact with the inner wall of the sliding cavity;

[0008] The telescopic inner tube is equipped with a flow monitoring component, and a display meter is fixedly connected to the circumferential surface of the telescopic inner tube.

[0009] Preferably, the left end of the telescopic inner tube is fixedly connected to a first connecting flange, and the right end of the fixed outer tube is fixedly connected to a second connecting flange. Both the first and second connecting flanges have multiple mounting holes inside, and the multiple mounting holes are arranged in a circular array. The arrangement of the first connecting flange, the second connecting flange, and the mounting holes facilitates the installation of the telescopic inner tube and the fixed outer tube.

[0010] Preferably, both the first connecting flange and the second connecting flange are provided with mounting grooves on their side walls, and a sealing gasket is fixedly connected inside the mounting groove. The sealing gasket is mainly used to improve the sealing performance when the first connecting flange and the second connecting flange are connected.

[0011] Preferably, a limiting ring is fixedly connected to the inner wall of the sliding cavity, and the limiting ring is located on the right side of the piston ring. The limiting ring is mainly used to limit and block the piston ring.

[0012] Preferably, a telescopic rod is fixedly connected between the first connecting flange and the second connecting flange. There are two telescopic rods, which are symmetrically arranged on the front and rear sides of the telescopic inner tube and the fixed outer tube. The telescopic rods are mainly used to limit the telescopic inner tube and the fixed outer tube to prevent relative rotation between them.

[0013] Preferably, the inner wall of the sealing ring is inclined, the outer wall of the extrusion ring is inclined, and the extrusion ring is used in conjunction with the sealing ring.

[0014] (III) Beneficial Effects

[0015] This invention provides a device for monitoring the discharge flow rate of ballast water in emergency situations. It has the following beneficial effects:

[0016] 1. This invention, by setting up a telescopic inner tube, a fixed outer tube, a sliding cavity, a sliding hole, a piston ring, and a spring, facilitates relative sliding between the telescopic inner tube and the fixed outer tube, and causes the metering chamber to expand and contract. When the ballast water discharge valve is opened, the impact force of the ballast water is buffered by the action of the spring, which can effectively buffer the flow monitoring components inside the telescopic inner tube and help improve the service life of the monitoring equipment.

[0017] 2. This invention, by setting an extension groove, a sealing ring, a compression ring, and a spring, compresses the spring when the telescopic inner tube and the fixed outer tube slide relative to each other. The spring's reaction force then compresses the compression ring, causing it to gradually enter the extension groove. Simultaneously, the compression ring compresses the sealing ring, improving the sealing performance between the sealing ring and the piston ring. This prevents excessive pressure of the ballast water from causing leakage from the piston ring, thus ensuring the sealing performance of the monitoring equipment. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example:

[0026] like Figure 1-5As shown, this embodiment of the invention provides a ballast water emergency discharge flow monitoring device, including a telescopic inner pipe 1 and a fixed outer pipe 2. The telescopic inner pipe 1 and the fixed outer pipe 2 are designed to facilitate 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 by the action of the spring 10, which can effectively buffer the flow monitoring components inside the telescopic inner pipe 1, thus improving the service life of the monitoring device. The right side of the fixed outer pipe 2 is the water inlet, and a sliding cavity 3 is provided inside the fixed outer pipe 2. A sliding hole 4 is provided on the left side wall of the fixed outer pipe 2, and the telescopic inner pipe 1 is slidably connected to the inside of the sliding hole 4. The sliding hole 4 facilitates the sliding of the telescopic inner pipe 1 on the fixed outer pipe 2. A piston ring 5 is fixedly connected to one end of the telescopic inner pipe 1 inside the sliding cavity 3, and the piston ring 5 is slidably connected to the inner wall of the sliding cavity 3. The piston ring 5 is mainly used to achieve a sealing effect and prevent leakage during the sliding process of the telescopic inner pipe 1 and the fixed outer pipe 2. An extension groove 7 is provided on the left side wall of the piston ring 5. The extension groove 7 is provided to facilitate the movement of the compression ring 9 after being compressed by the spring 10. When the compression ring 9 moves under the compression of the spring 10, it will compress the sealing ring 8, which improves the sealing performance between the sealing ring 8 and the piston ring 5 and prevents the ballast water from leaking from the piston ring 5 due to excessive pressure. This ensures the sealing performance of the monitoring equipment. The compression ring 9 is slidably connected to the circumference of the telescopic inner tube 1. The compression ring 9 mainly works with the compressed spring 10 to compress the sealing ring 8. The spring 10 is fixedly connected to the left side wall of the compression ring 9. The spring 10 also has the function of restoring the telescopic inner tube 1 and the fixed outer tube 2 to their 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 sealing ring 8 is also fixedly connected to the left side wall of the piston ring 5, and the sealing ring 8 is located outside the extension groove 7. The sealing ring 8 is in contact with the inner wall of the sliding cavity 3.

[0027] The telescopic inner tube 1 is equipped with a flow monitoring component, which is essentially a turbine flow meter. 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 to a first connecting flange 11, and the right end of the fixed outer tube 2 is fixedly connected to a second connecting flange 12. Both the first connecting flange 11 and the second connecting flange 12 have multiple mounting holes 13 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. Both the first connecting flange 11 and the second connecting flange 12 have mounting grooves 14 on their side walls. A sealing gasket 15 is fixedly connected inside the mounting groove 14. 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. There are two telescopic rods 17, which are symmetrically arranged on the front and rear sides of the telescopic inner tube 1 and the fixed outer tube 2. The telescopic rods 17 are mainly used to limit the telescopic inner tube 1 and the fixed outer tube 2 to prevent relative rotation between them.

[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 limiting ring 6 is mainly used to limit and block the piston ring 5. The inner wall of the sealing ring 8 is inclined, and the outer wall of the extrusion ring 9 is inclined. The extrusion ring 9 is used in conjunction with the sealing ring 8. The extrusion ring 9 is correspondingly set with the extension groove 7. The sealing ring 8 and the extrusion ring 9 are provided with inclined surfaces to facilitate the extrusion ring 9 to extrude the sealing ring 8 and improve the sealing performance of the piston ring 5. All materials in this application are made of corrosion-resistant materials.

[0030] Working principle: In use, the telescopic inner tube 1 and the fixed outer tube 2 are first installed 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 installation, 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 compression ring 9. The compression ring 9 gradually enters the extension groove 7. At the same time, the compression ring 9 squeezes the sealing ring 8, which improves the sealing performance between the sealing ring 8 and the piston ring 5, and prevents the ballast water from leaking from the piston ring 5 due to excessive pressure. In addition, the relative sliding of the telescopic inner tube 1 and the fixed outer tube 2 is buffered by the spring 10 to prevent damage to the flow monitoring components inside the telescopic inner tube 1.
