Description

Technical Field

[0001] This invention belongs to the field of vibration reduction technology for special vehicles, specifically relating to a vibration reduction structure for seawater cooling pipes penetrating the cabin of an amphibious vehicle. Background Technology

[0002] For amphibious armored vehicles, the engine generates significant heat in seawater conditions, requiring direct cooling with seawater. This seawater is drawn into stainless steel pipes by a seawater pump, flows through the engine compartment bulkhead, cools the engine, and then exits the engine compartment and is discharged outside the vehicle via another through-cabin pipe. Placing most of the pipes and connectors outside the engine compartment effectively prevents leaks caused by poor sealing, thus avoiding seawater entering the engine compartment and damaging it.

[0003] The seawater pipeline connects to the engine at one end and passes through the engine compartment at the other. Due to the severe vibrations generated during vehicle operation and engine operation, the seawater pipeline, without vibration damping devices, can tear under severe vibration. Furthermore, due to the structural limitations of the engine compartment, replacing damaged pipeline seals is extremely cumbersome. Therefore, those skilled in the art need to improve the cooling pipeline structure to meet requirements for vibration damping, quick installation, and extended service life, thereby addressing the aforementioned problems in the existing technology. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this invention is: how to improve the structure of cooling pipes to avoid tearing of seawater pipes, and to meet the requirements of vibration reduction, quick installation and service life.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides a seawater cooling pipe through-cabin vibration damping structure for amphibious vehicles. The seawater cooling pipe through-cabin vibration damping structure for amphibious vehicles includes: a power compartment partition 1, a mesh support plate 2, a first stainless steel seawater pipe inside the power compartment 3, a second stainless steel seawater pipe outside the power compartment 4, a double-spherical flexible rubber vibration damper 5, a corrugated sealing rubber pipe 6, a first sealing ring 7a, and a second sealing ring 7b.

[0008] The second stainless steel seawater pipe 4 and the mesh support plate 2 are both located on the left side of the power compartment bulkhead 1, outside the power compartment; the first stainless steel seawater pipe 3, the double-ball flexible rubber vibration damper 5, and the corrugated sealing rubber pipe 6 are all located on the right side of the power compartment bulkhead 1, inside the power compartment; a first sealing ring 7a and a second sealing ring 7b are provided to seal the connection points between the double-ball flexible rubber vibration damper 5 and the two stainless steel pipes from both ends.

[0009] Two stainless steel pipes are used for the circulation of seawater, guiding seawater into the engine compartment to cool the engine and out of the engine compartment.

[0010] The double-spherical flexible rubber vibration damper 5 is used for the connection between the internal and external seawater pipelines of the power compartment and has good vibration damping performance;

[0011] The corrugated sealing rubber tube 6 serves both sealing and vibration damping functions, and is wrapped around the outside of the double-ball flexible rubber vibration damper 5.

[0012] The mesh support plate 2 is used for support and drainage.

[0013] The power compartment bulkhead 1 includes any form of power compartment bulkhead or cavity wall surface, which serves as the attachment point for seawater pipelines to pass through and support the compartment.

[0014] The double-sphere flexible rubber vibration damper 5 is configured as follows: the middle part is an integrally connected double-sphere rubber structure, and the two sides are metal flanges with installation through holes.

[0015] The double-sphere flexible rubber vibration damper 5 has a double-sphere rubber structure in the middle made of rubber material that is corrosion-resistant, acid and alkali-resistant, and low-temperature resistant, including EPDM rubber.

[0016] The first sealing ring 7a and the second sealing ring 7b are made of polytetrafluoroethylene, which has the effect of preventing seawater corrosion.

[0017] All fasteners, including the bolts connecting the first stainless steel seawater pipe 3 to the double-ball flexible rubber vibration damper 5 and the bolts connecting the second stainless steel seawater pipe 4 to the double-ball flexible rubber vibration damper 5, are coated with Dacromet for corrosion protection.

[0018] The second stainless steel seawater pipe 4 and the first stainless steel seawater pipe 3 are both made of 316L stainless steel.

[0019] The second stainless steel seawater pipe 4 is connected to the mesh support plate 2 and the second sealing ring 7b on one side of the double-ball flexible rubber vibration damper 5 by bolts.

[0020] The other side of the double-spherical flexible rubber vibration damper 5 is connected in sequence to the first sealing ring 7a and the first stainless steel seawater pipe 3 by bolts. The above structure combination forms a basic seawater circulation pipeline.

[0021] Specifically, the mesh support plate 2 in the basic seawater pipeline is fixed to the engine room bulkhead 1 by bolts, so that the basic seawater pipeline is supported on the engine room wall and avoids being suspended through the cabin.

[0022] The first stainless steel seawater pipe 3 has two rows of mounting holes along its outer edge. The inner ring mounting holes are used to connect with the double-ball flexible rubber damper 5, and the outer ring mounting holes are used to connect with the corrugated sealing rubber pipe 6.

[0023] In this process, the outer ring of the first stainless steel seawater pipe 3 is connected to one side of the corrugated sealing rubber pipe 6 via bolts. After the corrugated sealing rubber pipe 6 is fitted around the first stainless steel seawater pipe 3, the other side of the corrugated sealing rubber pipe 6 is fixed to the engine compartment bulkhead 1 via bolts. That is, the corrugated sealing rubber pipe 6 encloses the double-spherical flexible rubber vibration damper 5 inside, which can both seal the area to prevent seawater from flowing into the engine compartment and dampen vibrations, eliminating some of the high-frequency vibrations of the first stainless steel seawater pipe 3 on the engine side and transmitting them to the second stainless steel seawater pipe 4.

[0024] The mesh support plate 2 is located between the corrugated sealing rubber tube 6 and the double-spherical flexible rubber damper 5. The mesh support plate 2 is provided with a large number of drainage holes. When a sealing failure occurs and seawater flows into the corrugated sealing rubber tube 6, the seawater can flow out through the drainage holes to avoid flowing into the engine compartment.
