Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, and in particular to a novel suction port butterfly door sealing equipment. Background Technology

[0002] When the ship is not under construction, the suction port on the side of the ship needs to be sealed. The suction port sealing equipment slides down the track to the suction port end of the ship to seal it, preventing water from entering the ship's hull from the suction port. This facilitates the repair of the internal piping system and gate valves and is a key sealing component related to the safety of the ship.

[0003] In the existing technology, the hull intake end is generally sealed with rubber rings or rubber strips. Due to the pressure of seawater, the sealing performance of the seals is not good, resulting in water leakage. This poses a safety hazard during ship downtime. Moreover, the installation and repair process is complicated, time-consuming, labor-intensive, and difficult to maintain. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a new type of suction port butterfly door sealing equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel suction port butterfly door sealing device includes a suction port door that is slidably mounted on a side rail, and further includes:

[0007] A base, which is fixedly mounted on the side of the suction port door near the ship's side suction port;

[0008] An outer pressure ring, which is fixed to the outer ring of the base;

[0009] An inner pressure ring, which is fixed to the inner ring of the base;

[0010] And a butterfly-shaped air tire seal ring, wherein the butterfly-shaped air tire seal ring is movably abutted against the base and is placed between the inner pressure ring and the outer pressure ring;

[0011] The butterfly-shaped pneumatic tire seal ring, along with the inner and outer pressure rings, forms a sealing surface on the same side end face that abuts against the side intake port end face.

[0012] Preferably, fastening bolts are provided between the outer pressure ring and the base, and between the inner pressure ring and the base.

[0013] Preferably, the butterfly-shaped pneumatic tire seal ring includes a pneumatic tire body and an annular pressure strip disposed on the outer side of the pneumatic tire body, and both the outer pressure ring and the inner pressure ring are provided with annular pressure grooves that cooperate with the annular pressure strip.

[0014] Preferably, the suction door includes a door body and sliding seats fixed on both sides of the door body and slidably connected to the side rails.

[0015] Preferably, an inclined limiting plate is fixed on the slide block, and the inclined limiting plate moves against the wedge-shaped stop on the side rail.

[0016] Preferably, the suction door and the base are provided with an inflation pipe system that communicates with the butterfly-shaped air tire sealing ring, and a nylon block is provided at the interface of the inflation pipe system on the suction door.

[0017] Preferably, the suction door is provided with an elastic element between the support plate and the nylon block, and a top rod is fixed on the side rail to move against the bottom of the nylon block.

[0018] Compared with the prior art, this utility model provides a novel suction port butterfly door sealing device, which has the following beneficial effects:

[0019] 1. This new type of suction port butterfly door sealing equipment solves the problem of water leakage caused by poor sealing performance of existing suction port seals due to seawater pressure by placing the butterfly-shaped pneumatic tire sealing ring in the sealing cavity formed by the outer pressure ring and the inner pressure ring.

[0032] like Figures 1 to 7As shown, this embodiment proposes a novel suction port butterfly door sealing device, including a suction port door 1 slidably mounted on a side rail 7, and further including: a base 8, an outer pressure ring 2, an inner pressure ring 4, and a butterfly-shaped pneumatic tire sealing ring 3. The base 8 is fixedly mounted on the side of the suction port door 1 near the ship's side suction port, the outer pressure ring 2 is fixedly mounted on the outer ring of the base 8, the inner pressure ring 4 is fixedly mounted on the inner ring of the base 8, and the butterfly-shaped pneumatic tire sealing ring 3 is movably abutted against the base 8 and placed between the inner pressure ring 4 and the outer pressure ring 2; wherein, the butterfly-shaped pneumatic tire sealing ring 3, the inner pressure ring 4, and the outer pressure ring 2 form a sealing surface on the same side end face that abuts against the end face of the side suction port;

[0033] Furthermore, fastening bolts 9 are provided between the outer pressure ring 2 and the base 8, and between the inner pressure ring 4 and the base 8;

[0034] Furthermore, the butterfly-shaped air tire sealing ring 3 includes an air tire body 301 and an annular pressure strip 302 disposed on the outside of the air tire body 301. Both the outer pressure ring 2 and the inner pressure ring 4 are provided with annular pressure grooves 10 that cooperate with the annular pressure strip 302.

[0035] Furthermore, an inflation pipe system 6 is provided on the suction door 1 and the base 8, which is connected to the butterfly-shaped air tire sealing ring 3. A nylon block 5 is provided at the interface of the inflation pipe system 6 on the suction door 1.

[0036] Specifically, the suction door 1 is slidably installed on the side rail 7. When the ship is not in operation, it slides down the rail to the suction inlet end face, serving as a base support for the seal. The base 8 is fixed to the side of the suction door 1 near the ship's side suction inlet and is used to support the outer pressure ring 2, the inner pressure ring 4, and the butterfly-shaped air tire seal ring 3. The outer pressure ring 2 and the inner pressure ring 4 are fixed to the outer and inner rings of the base 8 respectively by fastening bolts 9. The opposite end faces of the two form a sealing cavity. An annular pressure groove 10 is opened on the side wall of the cavity to limit the annular pressure strip 302 of the butterfly-shaped air tire seal ring 3 and prevent the butterfly-shaped air tire seal ring 3 from shifting. The butterfly-shaped air tire seal ring 3 can be quickly replaced by simply removing the fastening bolts 9, which greatly simplifies the maintenance process. The air tire body 301 is connected to an external air source through the inflation pipe system 6. The external air source injects pressurized air into the butterfly-shaped air tire seal ring 3 through the interface of the inflation pipe system 6. When the suction door 1 is not blocked from the side suction inlet, the interface of the inflation pipe system 6 is in an unsealed state and the interface is sealed by a nylon block 5 to prevent impurities from entering.

[0037] During the inlet sealing stage: the inlet door 1 slides down the track until the base 8 is aligned with the inlet end face on the side of the ship; compressed air is injected into the butterfly-shaped air tire seal ring 3 through the air inflation pipe system 6 interface, the air tire body 301 expands, and the butterfly-shaped air tire seal ring 3 expands in a directional manner under the constraint of both sides, forming a uniform pressure-bearing sealing surface; the pressure of the sealing surface is matched with the seawater pressure (≥ external water pressure) in real time to eliminate the risk of leakage.

[0038] Repair / Restoration Construction Phase: Stop inflation, retract and reset the butterfly-shaped air tire seal ring 3, and seal the inflation pipe interface 6 with nylon block 5 to prevent blockage; if the butterfly-shaped air tire seal ring 3 needs to be replaced, remove the fastening bolts 9 of the outer pressure ring 2 and the inner pressure ring 4, take out the old seal ring, install the new part and retighten the bolts 9, without removing the suction door 1;

[0039] This application solves the problem of water leakage caused by poor sealing performance of the existing suction door 1 seal due to seawater pressure by placing the butterfly-shaped pneumatic tire seal ring 3 in the sealing cavity formed by the outer pressure ring 2 and the inner pressure ring 4, which poses a safety hazard during ship downtime. Compared with traditional sealing strips, the butterfly-shaped pneumatic tire seal ring 3 has an increased sealing area and better sealing performance. The butterfly-shaped pneumatic tire seal ring 3 has a longer lifespan than sealing strips and is easy to disassemble and replace, which significantly reduces costs.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the suction door 1 further includes a door body 101 and a slide seat 102 fixed on both sides of the door body 101 and slidably connected to the side rail 7.

[0041] Furthermore, an inclined limiting plate 1021 is fixed on the slide 102, and the inclined limiting plate 1021 moves against the wedge-shaped stop 701 on the side rail 7.

[0042] Specifically, when the side suction port sealing work is required, the suction port door 1 slides down the side track 7 at a constant speed through the slide seat 102 under the action of gravity to avoid deviation. When the slide seat 102 approaches the end of the track, the inclined limiting plate 1021 contacts the inclined surface of the wedge-shaped stop 701. Under the action of the component force of gravity, the inclined limiting plate 1021 slides along the wedge-shaped surface until it is completely pressed, so that the door 101 stops precisely in the sealing position.

[0043] like Figure 3 As shown, in a preferred embodiment, based on the above method, the suction door 1 is further provided with an elastic element 501 between the support plate and the nylon block 5, and a top rod 702 is fixed on the side rail 7 to move against the bottom of the nylon block 5.

[0044] When the door 101 slides down and is positioned, the suction door 1 slides down along the side rail 7, and the inclined limiting plate 1021 of the slide block 102 abuts against the wedge-shaped stop 701. During this period, the top rod 702 abuts against the nylon block 5, the nylon block 5 moves upward and no longer blocks the interface of the inflation pipe system 6, the interface of the inflation pipe system 6 is fully exposed, and compressed air is injected through the connection of the external air source. The butterfly-shaped air tire sealing ring 3 expands to perform the sealing work. When the door 101 moves upward, inflation stops, the butterfly-shaped air tire sealing ring 3 contracts and resets, the nylon block 5 disengages from the top rod 702 and resets under the push of the elastic element 501, and the nylon block 5 blocks the interface of the inflation pipe system 6 to prevent seawater and silt from entering and causing corrosion of the air tire or blockage of the air passage. The elastic element 501 can be a component with strong elastic pre-tightening force, such as a spring or elastic telescopic rod, depending on the actual situation, to ensure that the nylon block 5 always fits the interface when sealing, and to prevent the seal from loosening due to ship vibration.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
