Description

Technical Field

[0001] This utility model relates to the shipbuilding field, and in particular to a ventilation hose fixer for a ventilation fan of an oil tanker. Background Technology

[0002] Aframax tankers are economical tankers for short-haul transportation, with a deadweight tonnage between 80,000 and 120,000 tons. They offer high economic efficiency and flexibility, making them particularly suitable for navigation in ice-covered areas. Among them, the 114,000-ton Aframax tanker, with its moderate size and draft, can navigate in relatively shallow waters, making it one of the best vessel types for navigating the Bering Sea ice zone.

[0003] Aframax-type tanker ventilation fans are ventilation systems specifically designed for product oil tankers. They are used to force air exchange within the tank compartments in special ship environments (such as salt spray, oil mist, temperature fluctuations, and ship rolling) to ensure safety, control temperature, and improve air quality. Product oil tankers transport flammable and explosive liquids such as gasoline and diesel, and explosive gas mixtures may accumulate in the compartments. The ventilation fans reduce the concentration of flammable gases through forced ventilation to prevent them from reaching explosive limits. Simultaneously, their explosion-proof design (such as a spark-free, airtight structure) prevents sparks from mechanical friction or electrical faults. The ship's propulsion system (such as main engine and auxiliary engines) generates a large amount of heat; if this heat is not dissipated in time, it may cause equipment overheating.

[0004] Thermal damage or excessively high cabin temperature. The ventilation system continuously supplies fresh air and exhausts hot air to maintain the cabin temperature within a reasonable range. In the engine room, equipment operation generates pollutants such as oil fumes and fumes, while living quarters generate carbon dioxide and odors due to personnel activity. The ventilation system dilutes the concentration of pollutants by changing the air volume, ensuring the health of the crew.

[0005] The ventilation hoses of the air exchangers on oil tankers need to be secured. In the existing technology, wire wrapping or tape wrapping is mainly used. Wire wrapping requires clamping with pliers, which can easily damage the ventilation hose and is not easy to operate. Tape wrapping has poor sealing and is easy to fall off, affecting the use of the ventilation hose. Utility Model Content

The fixing device is used to fix the ventilation hose 7 of the air exchanger without damaging the hose. The overall operation is simple. The wrapping of the steel wire rope 5 makes the seal strong, not easy to fall off, reduces waste, and can be reused.

[0065] Example 2

[0066] As one embodiment of this application, such as Figures 3 to 6 , Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the bottom end of the fixed cylinder 1 is connected to a fixed housing 9, and both sides of the fixed housing 9 are provided with annular support bars 10. The fixed housing 9 and the annular support bars 10 are connected by a transmission mechanism 11.

[0067] The control component 11 includes a rotating shaft 111, the two ends of which are rotatably connected to the inner wall of the fixed housing 9.

[0068] A central gear 112 is connected to the surface of the rotating shaft 111. Movable racks 113 are meshed on both sides of the central gear 112. The movable racks 113 are slidably connected to the side of the fixed housing 9. One end of the movable racks 113 is connected to one side of the annular support bar 10.

[0074] A limiting ring 125 is provided on the outer side of the connecting plate 123, and a threaded lifting ring 126 is connected to the top of the limiting ring 125.

[0075] In this technical solution, the locking component 12 locks the control component 11, thereby locking the position of the annular support bar 10.

[0076] The lower part of the side surface of the fixed cylinder 1 is provided with external threads.

[0077] The top surface of the fixed housing 9 has multiple sliding openings, and the surface of the connecting column 122 is slidably connected to the top surface of the fixed housing 9 through the sliding openings.

[0078] In this technical solution, the locking rack 121 and the connecting plate 123 can be connected by the connecting post 122.

[0079] The side of the connecting plate 123 away from the elastic connector 124 is connected to a plurality of elastic connectors 124, and the end of the elastic connector 124 away from the connecting plate 123 is connected to the side of the fixed cylinder 1.

[0081] In use, one side of the annular support bar 10 can be pulled, which will drive the corresponding moving rack 113 to move, thereby driving the central gear 112 to rotate, which in turn drives the rotating shaft 111 to rotate. The rotation of the central gear 112 drives the other moving rack 113 to move, so that the two moving racks 113 can move in different directions, thereby allowing the annular support bars 10 on both sides to move towards or away from each other. Adjusting the distance between the two annular support bars 10 can change the support and fixing area of ​​the fixture according to the model of the ventilation hose 7 of the air exchanger.

[0082] Example 3

[0086] The rope hook 4 is connected to an anti-detachment hook 133 on one side.

[0087] In this technical solution, the anti-detachment hook 133 can prevent the wire rope 5 from slipping off the fixed rope hook 4.

[0089] The outer side of the threaded adjusting ring 131 is connected to two symmetrically distributed fixed ring plates 134. The fixed ring plates 134 are rotatably connected to a plurality of rolling balls 135 arranged in a ring array on the side near the fixed rope hook 4. The rolling balls 135 are in contact with the fixed rope hook 4.

[0090] The rolling ball 135 can limit and guide the rotation of the fixed rope hook 4, making the rotation of the fixed rope hook 4 smoother.

[0091] When in use, the rope fixing hook 4 drives the anti-detachment rotating ring 132 to rotate around the threaded adjusting ring 131, thereby adjusting the angle of the rope fixing hook 4, making the installation of the wire rope 5 more flexible.
