Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to a ship fire door with up and down ventilation. Background Art

[0002] Accidents are inevitable during a ship's voyage, and fire is a common disaster on board. To minimize damage from a fire, ship cabin doors are constructed of fire-resistant materials. Because cabins are sealed, exhaust fans alone cannot provide sufficient fresh air. Therefore, fire doors are typically constructed with a direct vent to allow fresh air in. However, this direct vent reduces the fire door's effectiveness. In the event of a fire, smoke can spread through the vent, compromising safety on board.

[0003] For example, a fire door with up-down ventilation, as disclosed in publication number CN202273559U, is characterized in that it comprises a door frame (1) and a door leaf (2), wherein the door leaf (2) is mounted in the door frame (1) and hinged to the door frame (1), wherein a ventilation channel (6) is provided in the door leaf (1), wherein the ventilation channel (6) is in a "Z" shape, wherein one end of the "Z" shape is connected to an outer air inlet (7) of the door leaf (2), and the other end of the "Z" shape is connected to an inner air outlet (8) of the door leaf (2). This fire door for ships with up-down ventilation adopts an up-down ventilation method, with one high and one low ventilation opening being opened on the inner and outer sides of the door leaf, so that external noise cannot be directly transmitted into the cabin, but needs to be transmitted in the ventilation channel inside the door leaf, thereby reducing the intensity of the noise and improving the sound insulation effect of the fire door. In addition, an escape hatch is provided at the bottom of the fire door, and people can quickly escape by simply kicking open the escape hatch wind grille in front of the escape hatch.

[0004] The above technical solution has the problem of being unable to prevent the spread of fire smoke in actual application.

[0005] Therefore, it is necessary to invent a marine fire door that is ventilated up and down to solve the above problems. Utility Model Content

A plurality of sound-absorbing blocks 4 are fixedly mounted on both sides of the partitions 3. The plurality of sound-absorbing blocks 4 are each configured as a conical structure. The conical structure allows sound to be reflected between the plurality of sound-absorbing blocks 4, thereby achieving a noise reduction and silencing effect.

[0024] Specifically, ventilation doors 5 are fixedly provided at both ends of both sides of the door body 2, and a plurality of ventilation slots 6 are provided through the middle of the ventilation door 5, and the ventilation slots 6 are provided in a strip-shaped structure;

[0025] More specifically, a fixed cylinder 7 is fixedly provided in the middle of the inner side of the door body 2, and four through slots 8 are opened on the outer side of the fixed cylinder 7. Connecting pipes 9 are fixedly provided at the notches of the four through slots 8, and the four connecting pipes 9 are respectively fixedly provided on the inner sides of the four ventilation doors 5. A movable rod 10 is provided in the middle of the inner side of the fixed cylinder 7, and four baffles 11 are provided around the outer side wall of the movable rod 10. The four baffles 11 divide the interior of the fixed cylinder 7 into four spaces. When the baffles 11 rotate, the space inside the fixed cylinder 7 is connected to the connecting pipes 9.

[0026] In addition, a transmission bevel gear 12 is fixedly provided in the middle of the movable rod 10, and a transmission rod 13 is provided through the middle of both sides of the door body 2 through a bearing, and one end of the transmission rod 13 is fixedly provided with a driving bevel gear 14 corresponding to the transmission bevel gear 12, and one end of the transmission rod 13 is fixedly provided with a positioning seat 15 with a circular structure, and a plurality of positioning grooves 16 are opened around the outer wall of the positioning seat 15, and a limiting sleeve 17 is fixedly provided in the middle of both sides of the door body 2, and the limiting sleeve 17 is sleeved on the outer side of the positioning seat 15, and the outer middle of the limiting sleeve 17 is fixedly provided. An extension sleeve 18 is fixedly provided on the top, and a limit block 19 is inserted into the interior of the extension sleeve 18. One end of the limit block 19 is set to a hemispherical structure corresponding to the positioning groove 16, and a spring is provided between the other end of the limit block 19 and the extension sleeve 18. The limit block 19 is inserted into the positioning groove 16 under the action of the spring. Since one end of the limit block 19 is set to a hemispherical structure, when the transmission rod 13 is rotated by an external force, the positioning groove 16 squeezes the limit block 19 to make it inserted into the extension sleeve 18, so as to facilitate the rotation of the transmission rod 13;

[0027] Moreover, a limiting slide groove 20 is provided on the inner side wall of the extension sleeve 18, and a limiting slip ring 21 corresponding to the limiting slide groove 20 is fixedly provided at one end of the limiting block 19. The limiting slip ring 21 cooperates with the limiting slide groove 20 to limit the sliding range of the limiting block 19, so as to prevent the limiting block 19 from being inserted too deeply into the positioning groove 16 and affecting the rotation of the transmission rod 13 when the force is applied;

[0028] At the same time, a hand wheel 22 is fixedly provided at one end of the transmission rod 13 , and a plurality of anchor rods 23 in a “cross” structure are fixedly provided on the outer side wall of the door frame 1 . The provision of the anchor rods 23 facilitates the installation of the door frame 1 .

[0029] Working principle of this utility model:

[0030] When the device is in use, the handwheel 22 is rotated to drive the transmission rod 13 to rotate. The transmission rod 13 can drive the transmission bevel gear 12 to rotate by driving the bevel gear 14, and the transmission bevel gear 12 can drive the movable rod 10 to rotate. The movable rod 10 drives the four baffles 11 to rotate. The four baffles 11 divide the interior of the fixed cylinder 7 into four spaces. During the rotation of the baffle 11, the space inside the fixed cylinder 7 is connected with the connecting pipe 9, so that the connection between the two ventilation doors 5 on both sides of the door body 2 can be realized. At this time, the air can enter the connecting pipe 9 through the ventilation groove 6, and then pass through the fixed cylinder 7 to drive the ventilation groove 6 on the other ventilation door 5 to be discharged to achieve the ventilation effect. When a fire occurs or ventilation is not required, the position of the baffle 11 can be adjusted so that the baffle 11 is misaligned with the connecting pipe 9. At this time, the four connecting pipes 9 can be blocked separately to limit the ventilation effect of the fire door.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
