[0002] The ventilation duct is an important setting on the ship's hull. The ventilation duct is connected to the interior of the engine room to help the air circulation in the engine room. A fire damper is arranged in the existing ventilation duct. After a fire breaks out in the engine room, one end of the cylinder body is sealed by the fire damper to prevent the fire from spreading.
[0003] The operator needs to regularly check the condition of the fire damper in the ventilation duct to avoid damage to the fire damper. However, since the fire damper is located inside the cylinder cap, the operator cannot directly observe the fire damper and can only judge whether the fire damper is damaged by other means such as hearing.
[0004] This judgment method has certain errors, and if the inspection is not in place, it is easy to leave potential safety hazards. Content of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an air inlet structure of the engine room on a fiberglass ship, which has the effect of ensuring 100% accuracy of detection and eliminating potential safety hazards.

[0012] In a preferred embodiment, the present utility model can be further configured as follows: Two guide rods are symmetrically arranged at the top of the inner wall of the barrel cap. One end of each of the two guide rods passes through the fire damper plate, and the guide rods are slidably connected to the fire damper plate.
[0013] One end of each of the two guide rods extends into the barrel body.
[0014] In a preferred embodiment, the present utility model can be further configured as follows: The determination component includes a sleeve, which is fixed on the inner wall of the barrel cap, and the plane where the top of the sleeve is located is flush with the plane where the top of the barrel body is located.
[0015] A sliding rod is slidably arranged in the sleeve. A spring is arranged between the sliding rod and the corresponding sleeve, and two ends of the spring are respectively fixed to the bottom of the inner wall of the corresponding sleeve and one end of the corresponding sliding rod.
[0016] When the spring is in a natural state, a part of the sliding rod is always located outside the corresponding sleeve.

Specific implementation manner
[0028] The following further elaborates on the present utility model in conjunction with the attached drawings.
[0029] Embodiment:
[0030] Referring to Figures 1 - 3 as shown, a glass fiber reinforced plastic ship engine room air intake structure disclosed by the present utility model includes a ventilation cylinder 1. The ventilation cylinder 1 is arranged on the deck, and the bottom end of the ventilation cylinder 1 is located inside the engine room.
[0031] The ventilation cylinder 1 includes a cylinder body 11, a cylinder cap 12 and an annular filter plate 13. The annular filter plate 13 is fixedly sleeved on the upper half of the outer peripheral surface of the cylinder body 11, and the annular filter plate 13 is fixed to the inner peripheral wall of the cylinder cap 12.
[0032] A fire damper 2 is arranged inside the cylinder cap 12, and the fire damper 2 is located directly above the cylinder body 11. A moving component 3 is arranged on the cylinder cap 12, and the moving component 3 drives the fire damper 2 to move, so that the fire damper completely shields the top opening of the cylinder body 11.
[0033] The moving component 3 includes a screw 31. The screw 31 is penetrated through the cylinder cap 12, and the screw 31 is threadedly connected to the cylinder cap 12. The top of the fire damper 2 is provided with a first fixing rod 32. One end of the first fixing rod 32 extends into the screw 31, and the first fixing rod 32 is rotatably connected to the screw 31. A knob 33 is arranged at one end of the screw 31 located outside the ventilation cylinder 1.
[0034] Two guide rods 5 are symmetrically arranged at the top of the inner wall of the cylinder cap 12. One end of each of the two guide rods 5 penetrates through the fire damper 2, and the guide rods 5 are slidably connected to the fire damper 2. One end of each of the two guide rods 5 extends into the cylinder body 11.
[0035] A number of judgment components 4 are provided on the barrel cap 12. The judgment component 4 judges whether the fire damper 2 completely shields the ventilation holes at one end of the barrel body 11. The judgment component 4 includes a sleeve 41. A number of sleeves 41 are evenly fixed on the inner wall of the barrel cap 12.
[0036] The plane where the top of the sleeve 41 is located is flush with the plane where the top of the barrel body 11 is located.
[0037] A number of first through holes 44 are evenly formed on the outer peripheral surface of the barrel cap 12. The number of the first through holes 44 is equal to the number of the sleeves 41. And the sleeve 41 shields the corresponding first through hole 44.
[0038] A second through hole 45 is formed on the outside of each sleeve 41. The inside of the first through hole 44 is communicated with the inside of the corresponding second through hole 45.
[0039] A sliding rod 42 is slidably arranged in the sleeve 41. A spring 43 is arranged between the sliding rod 42 and the corresponding sleeve 41. The two ends of the spring 43 are respectively fixed to the bottom of the inner wall of the corresponding sleeve 41 and one end of the corresponding sliding rod 42. When the spring 43 is in a natural state, a part of the sliding rod 42 is always located outside the corresponding sleeve 41.
[0040] The fire damper 2 is located above a number of sliding rods 42. During the movement of the fire damper, it will touch a number of sliding rods 42, thereby driving the movement of a number of sliding rods 42.
[0041] An indicating rod 46 is arranged on one side of each sliding rod 42. One end of the indicating rod 46 passes through the corresponding first through hole 44 and the corresponding second through hole 45. A guide rod 6 is vertically arranged in each first through hole 44. The guide rod 6 passes through the corresponding indicating rod 46, and the guide rod 6 is slidably connected to the corresponding indicating rod 46.
[0042] As the fire damper 2 moves and drives the movement of a number of sliding rods 42, finally the sliding rods 42 are completely pressed into the corresponding sleeves 41. At this time, the bottom of the indicating rod 46 on the sliding rod 42 also contacts the bottom of the inner wall of the corresponding first through hole 44.
[0043] The implementation principle of the above embodiment is as follows:
[0044] The operator checks whether the fire damper 2 is working properly.
[0045] The operator rotates the knob 33. The knob 33 drives the screw 31 to rotate. The screw 31 moves downward along its own straight line direction. The screw 31 drives the fire damper 2 to move. The fire damper 2 moves along the direction where the two guide rods 5 are located.
[0046] During the movement of the fire damper 2, it first touches a number of sliding rods 42.
[0047] The fire damper 2 drives several sliding rods 42 to move. After being squeezed, the sliding rods 42 move towards the inside of the corresponding sleeves 41, and at the same time, the corresponding springs 43 are in an elastically compressed state.
[0048] When the sliding rods 42 move, they drive the corresponding indicating rods 46 to move.
[0049] When the bottom of the fire damper 2 touches the top port of the cylinder body 11, the fire damper 2 stops moving. At this time, the operator observes the positions of several indicating rods 46 and checks whether the bottoms of the indicating rods 46 are in contact with the bottoms of the inner walls of the corresponding first through holes 44.
[0050] If several indicating rods 46 are in contact with the bottoms of the inner walls of the corresponding first through holes 44, it means that the fire damper 2 plays a role in closing the port of the cylinder body 11. If the bottoms of one or more indicating rods 46 are not in contact with the bottoms of the inner walls of the first through holes 44, it indicates that the fire damper 2 fails to completely close the top port of the cylinder body 11 and repair work is required.
[0051] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
