Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and in particular relates to a cleaning connector for blowing out and cleaning hydraulic pipelines of ship hatches. Background Technology

[0002] In the process of ship design and construction, there are various ways to connect the piping of ship systems. Among them, flange connection is one of the most common methods and is widely used.

[0003] The hatch cover hydraulic system is a crucial system on a ship, controlling the opening and closing of hatch covers via hydraulic oil in pipelines. Due to the special nature of the internal medium, the pipelines undergo purging, cleaning, and pressure testing after fabrication. A narrow gap exists between the contact surfaces of a pair of hydraulic flanges, making it particularly easy for small weld slag, iron filings, stones, and other impurities to accumulate. The presence of these impurities can pose a significant threat to the stable and safe operation of the equipment.

[0004] Currently, the most common cleaning method involves cleaning the pipeline with a large amount of cleaning medium, or placing soft materials such as sponges inside as "cleaning bombs" to clean the pipeline. This method has high requirements for flow rate and velocity, and the "cleaning bombs" themselves are prone to detaching impurities, resulting in less than ideal cleaning results. Summary of the Invention

[0005] In view of the above problems, the purpose of this utility model is to overcome the technical problems and defects of the existing technology, and to flush the inside of the pipeline more simply and thoroughly.

[0006] This utility model is achieved using the following technical solution:

[0007] A cleaning connector for blowing out and cleaning hydraulic pipelines of ship hatches, characterized in that the cleaning connector includes a vibrating ring, a strong magnetic block, a guide magnetic block, a sealing block, and a cone plug;

[0008] The vibrating ring and the strong magnetic block are both located on the inner wall of the guide magnetic block, with the strong magnetic block positioned between the vibrating ring and the guide magnetic block. The inner wall of the vibrating ring is embedded in the outer wall of the pipeline connection flange. The sealing block is installed on the inner wall of one side of the guide magnetic block, thus sealing the vibrating ring and the strong magnetic block on one side. The conical plug is installed on the other side of the guide magnetic block, and the conical plug contacts the guide magnetic block, using friction to prevent displacement between the pipeline connection flange and the cleaning joint.

[0009] Furthermore, the guide magnetic block is a hollow frustum-shaped rubber block, and the interior of the guide magnetic block is embedded with multiple parallel winding second electric coils in a stepped manner. When the second electric coils are energized, a directional magnetic field is formed inside the guide magnetic block.

[0010] Furthermore, a boss structure is formed on the inner wall of the guide magnet, and the boss structure limits the vibration ring and the strong magnet.

[0011] Furthermore, the vibrating ring is a circular annular metal cavity containing metal bodies of varying sizes.

[0012] Furthermore, the strong magnetic block is a ring-shaped rubber block containing multiple parallel winding first electric coils inside. When the first electric coils are energized, a uniform magnetic field can be formed inside the strong magnetic block, and the magnitude and direction of the magnetic field can be adjusted by adjusting the magnitude and direction of the current.

[0013] Furthermore, the sealing block is a ring-shaped rubber block.

[0014] Furthermore, the cone plug is a frustum-shaped rubber block with an internal through hole. The cone plug is fitted onto the pipeline, and one end of the cone plug is in contact with one end of the guide magnet.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] 1. This utility model achieves rapid and thorough cleaning of the inside of the pipeline by installing a cleaning joint outside the pipeline connection flange; by using an additional magnetic field and resonance in conjunction with the flushing of the cleaning medium, it can quickly and thoroughly clean various impurities such as iron filings, welding slag, and stones inside the pipe.

[0017] 2. This utility model achieves the cleaning purpose by applying a uniform magnetic field and a directional magnetic field at the connecting flange, in conjunction with the cleaning medium; and compared with the traditional method, it has lower requirements for the flow rate and volume of the cleaning medium.

[0018] 3. This utility model uses the vibration of metal balls of different sizes filled in the vibrating ring to cause resonance of impurities in the pipeline, which facilitates the thorough blowing away and cleaning of impurities.

[0019] 4. This utility model adjusts the magnitude of the magnetic field by controlling the magnitude of the current flowing through the coil, thereby controlling the amplitude and frequency of the metal body and producing a better cleaning effect. Attached Figure Description

[0024] Figure 5 A schematic diagram of the conical plug structure provided in this embodiment of the utility model. Detailed Implementation

[0025] like Figure 1 As shown, this embodiment discloses a cleaning connector for blowing and cleaning hydraulic pipelines of ship hatches, including a vibrating ring 1, a strong magnetic block 2, a guide magnetic block 3, a sealing block 4, and a cone plug 5. The vibrating ring 1 and the strong magnetic block 2 are both located on the inner wall of the guide magnetic block 3, and the strong magnetic block 2 is located between the vibrating ring 1 and the guide magnetic block 3. The inner wall of the vibrating ring 1 is embedded in the outer wall of the connecting flange 7 of the pipeline 6. The sealing block 4 is installed on the inner wall of one side of the guide magnetic block 3, and the sealing block 4 seals the vibrating ring 1 and the strong magnetic block 2 on one side. The cone plug 5 is installed on the other side of the guide magnetic block 3, and the cone plug 5 is in contact with the guide magnetic block 3. The frictional force prevents the pipeline connecting flange and the cleaning connector from shifting.

[0026] Specifically, such as Figure 2 As shown, the vibration ring 1 is a circular metal cavity with an inner diameter the same as the outer diameter of the flange. It can be fitted over the connecting flange and is made of stainless steel, which provides sufficient strength and allows for effective vibration. The cavity of the vibration ring 1 contains a large number of circular metal spheres C of varying sizes. Under a changing magnetic field, these spheres can generate vibration frequencies and amplitudes of different sizes, causing resonance of impurities at the flange connection and dislodging them from the gap. Combined with the scouring force of the high-speed flowing cleaning medium, this facilitates the removal of impurities.

[0027] like Figure 3 As shown, the strong magnetic block 2 is a circular rubber block with an inner diameter equal to the outer diameter of the vibrating ring 1. The strong magnetic block 2 contains multiple parallel winding first electric coils A. When the first electric coil is energized, a strong and uniform magnetic field can be formed inside it. Affected by the magnetic field force, the metal impurities and iron filings remaining at the flange connection are moved by the magnetic field force, causing them to detach from the gap and making them easier to remove.

[0028] like Figure 4As shown, the guide magnetic block 3 is a frustum-shaped rubber block with a boss structure inside. After being embedded in the vibration ring 1 and the strong magnetic block 2, the boss structure limits the vibration ring 1 and the strong magnetic block 2. The guide magnetic block 3 has multiple parallel winding second electric coils B embedded in it in a stepped manner. When the second electric coil is energized, due to the obvious stepped distribution of the number of second electric coils, a directional magnetic field is formed inside it. This can apply a force to the metal impurities inside the pipeline in a direction that gradually increases in the magnetic field, causing them to move. At the same time, the metal ball inside the vibration ring 1 is affected by the mixed changing magnetic field force of the strong magnetic block 2 and the guide magnetic block 3, which causes irregular vibration, causing the internal impurities to resonate. Combined with the high-speed flowing cleaning medium, it can quickly and thoroughly remove them.

[0029] The sealing block 4 is a circular rubber block. When the vibrating ring 1 and the strong magnetic block 2 are embedded in the guide magnetic block 3, as... Figure 1 As shown, the valve is sealed from the tail end to prevent the vibration ring 1 and the strong magnetic block 2 from moving;

[0030] like Figure 5 As shown, the cone plug 5 is a frustum-shaped rubber block with a through hole inside, the size of which is the same as the outer diameter of the pipeline. The cone plug 5 is divided into upper and lower parts. After the flange position is fixed, the two half cone plugs are placed at the first end. The cone plug 5 and the guide magnetic block 3 are in contact with each other, and the friction force prevents the pipeline connection flange and the cleaning joint from being displaced.

[0031] The cleaning connector for blowing and cleaning hydraulic pipelines of ship hatches provided in this embodiment achieves rapid, efficient, and thorough cleaning of residual iron filings, welding slag, and non-metallic impurities inside the pipeline connecting flange by installing a cleaning connector on the outside of the pipeline connecting flange. The device applies a uniform magnetic field to the outside of the flange using a strong magnetic block, separating the residual iron filings at the flange joint gap from the flange body and suspending them in the cavity formed by the connecting flange. A magnetic force with the same direction as the cleaning medium flow is applied by a guide magnetic block, and the impurities are promptly cleaned by the combined force of the magnetic force and the scouring force of the medium. By adjusting the magnitude of the two magnetic fields, a vibrating ring is induced to vibrate the flange continuously at different frequencies, causing the non-metallic impurities inside the gap to move irregularly, facilitating the cleaning medium to clean them. The device adjusts the magnitude of the two magnetic fields by current, and is effective in cleaning residual impurities of different sizes, effectively broadening its application range.

[0032] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
