Description
Technical Field
The invention belongs to the technical field of ship components, and particularly relates to a fireproof air brake for a ship.
Background
The fire damper for ships is a common fire protection facility equipped on ships, is usually located between two fire protection areas, i.e. is usually arranged on two adjacent bulkheads of the ships, and is closed to reduce the oxygen content of the protected space (cut off the communication between the protected space and the outside atmosphere), isolate the fire source, cut off the spread of fire, and the like.
As is known in the art, shutters are important parts of the structural architecture of fire dampers, and are generally required to have a severe fire rating, for example, when tested in some form according to the corresponding standard requirements, not to allow deformation and not to allow a temperature rise within a specified reasonable time or not to exceed a specified value.
In the published chinese patent literature, it is seen that technical information related to marine fire protection fans, for example, CN207161811U recommends a "new fire protection damper", and the specific structure of the patent can be referred to in paragraph 0013 of the specification, since the thermal insulation layer is provided in the interlayer of the shutter (called blade) described therein, it can be considered that the sandwich structure can exhibit good thermal insulation. For another example, CN205007479U provides a "sealing device for a fire damper for a ship", which is substantially a sealing strip formed by silicone rubber, and the sealing strip is adhered to the upper and lower sides of the damper when in use, and after the damper is rotated to a closed state, the sealing cavities on the two sides of the sealing strip can effectively seal the gap between the damper and the mounting frame, as described in paragraphs 0007 and paragraphs 0015 to 0017 of the specification of CN 205007479U.
From a reading of the patent literature, which is not limited to the above examples: although both patents are addressed to improve the fire, thermal and/or sealing properties of the shutter, there are the following general disadvantages: since a group of gate plates is opened or closed (i.e. closed) under the action of the linkage pull rod, and since the gap between the two adjacent gate plates in the length direction is unavoidable, only the difference of the gap size is enough, neither of the two patents can achieve the desired closing and sealing effect between the gate plates when the fireproof air gate is in the closed state, and the technical proposal to be described below is generated under the background.

Detailed Description
In order to clearly understand the technical spirit and the advantages of the present invention, the applicant below describes in detail by way of example, but the description of the example is not intended to limit the technical scope of the present invention, and any equivalent changes made according to the present inventive concept, which are merely in form and not in material, should be considered as the technical scope of the present invention.
In the following description, all the concepts related to the directions or orientations of up, down, left, right, front and rear are based on the position state of fig. 1, and thus, it should not be understood as a particular limitation to the technical solution provided by the present invention.
Referring to fig. 1 to 3, there is shown a barrel 1, a shutter front end wind deflector 12 is fixed on a front cavity wall of a barrel cavity 11 of the barrel 1, and a shutter rear end wind deflector 13 is fixed on a rear cavity wall of the barrel cavity 11 of the barrel 1 and at a position corresponding to the shutter front end wind deflector 12; a linkage rod 2 and a group of gate plates 3 are shown, the linkage rod 2 is hinged with the group of gate plates 3, the group of gate plates 3 are same in thickness, the front ends of the gate plates are pivotally supported on the front-end wind blocking seats 12 of the gate plates, the rear ends of the gate plates are pivotally supported on the rear-end wind blocking seats 13 of the gate plates, the group of gate plates 3 are respectively composed of gate plate panels 31, gate plate bottom plates 32 and heat insulation filling layers 33 (shown in figure 3), the two sides (the left side and the right side of the position state shown in figure 1) of the gate plate panels 31 and the gate plate bottom plates 32 in the length direction and the two ends (the front ends and the rear ends of the position state shown in figure 1) of the gate plate panels 31 and the gate plate bottom plates 32 are jointed with each other to form an integral structure, and the heat; a first flashboard limiting strip I4 a and a second flashboard limiting strip II 4b are shown, wherein the first flashboard limiting strip I4 a is fixed on the cavity wall of the cylinder cavity 11 at a position corresponding to a position between the left end of the flashboard front-end wind shielding seat 12 and the left end of the flashboard rear-end wind shielding seat 13, and the second flashboard limiting strip II 4b is also fixed on the cavity wall of the cylinder cavity 11 at a position corresponding to a position between the right end of the flashboard front-end wind shielding seat 12 and the right end of the flashboard rear-end wind shielding seat 13 and corresponds to the first flashboard limiting strip I4 a; and the flashboard opening and closing pneumatic actuator 5 is arranged on the outer wall of the barrel 1 at a position corresponding to the front end of the middle flashboard in the group of flashboards 3, and is connected with the front end of the middle flashboard.
Since the left edge of the first gate plate on the left side and the right edge of the second gate plate on the right side in the gate plate 3 are both arc-shaped (also referred to as "C-shaped"), the first gate plate limiting strip i 4a and the second gate plate limiting strip ii 4b are also arc-shaped (also referred to as "C-shaped"). Since the structure, action mechanism, etc. of the shutter opening and closing pneumatic actuator 5 illustrated in fig. 1 belong to the known technologies, for example, refer to the "new fire damper" recommended by chinese patent document CN207161811U and the "limit switch pneumatic actuator" provided by CN110131470A, etc., the applicant will briefly describe the following: the shutter opening and closing pneumatic actuator 5 is normally used in cooperation with an electromagnetic valve or the like, and when the pneumatic actuator is energized, compressed air drives the cylinder to move, so that the group of shutters 3 are rotated by 90 degrees to be opened, and before the shutters are opened, the automatic stop pin 6 shown in the figure is retreated from the shutters. When the power is lost, the air cylinder reversely rotates for 90 degrees, and the group of gate plates 3 are closed. Since the shutters 3 are closed in the air loss state, if the shutters 3 are to be opened, the opening operation is completed by manual driving, for example, by turning the cylinder by 90 ° with an operating handle. Fig. 1 and 3 show a state in which a group of shutters 3 is in a closed state.
