DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] A preferred embodiment of a marine pneumatic remote-controlled shutter device of the present invention is as follows: Figures 1 to 7 As shown, the marine pneumatic remote-controlled shutter device includes a window frame 1, blades 2, a linkage pull rod 3, a driving cylinder 4, an emergency handle 5, a transmission assembly and a rotary valve 6.

[0029] The window frame 1 is a rectangular frame structure formed of sheet metal. A base plate 22 is welded to the bulkhead 21 of the ship. This base plate 22 is provided with threaded holes, and the window frame 1 is fixed to the base plate 22 with fixing bolts 23. The blades 2, linkage rod 3, drive cylinder 4, emergency handle 5, and transmission assembly are all mounted on the frame 1. Lifting lugs 7 are welded to the top of the frame 1. Two lifting lugs 7 are spaced apart on either side of the frame 1, facilitating lifting and installation.

[0030] Several blades 2 are spaced apart vertically, each with screws securing both ends to a horizontally extending shaft 8. Bushings 9 are welded and fixed to the window frame 1, and the shaft 8 rotates within the bushings 9. The blades 2 are assembled to the window frame 1 by rotating about a horizontal axis via the shafts 8 and bushings 9. The blades 2 are Z-shaped, with flanges at the top and bottom of each blade 2. When the blades 2 are vertically aligned, the flanges of two adjacent blades 2 interlock, closing the blinds. When the blades 2 are tilted or horizontally aligned, the blades 2 separate, opening the blinds.

[0031] The linkage rod 3 is vertically arranged in the frame and is rotatably assembled with each blade 2 via a pin 10. When the up-down position of the linkage rod 3 changes, the pin 10 drives the blade 2 to rotate around the rotation axis 8, thereby opening or closing the blinds. In this embodiment, the linkage rod 3 is made of angle steel to increase the structural strength of the linkage rod 3.

[0032] The output end of the transmission assembly is in transmission connection with the linkage rod 3, and the input end is in transmission connection with the emergency handle 5. The emergency handle 5 can drive the linkage rod 3 to move up and down through the transmission assembly, thereby opening or closing the blade 2. At the same time, the input end of the transmission assembly is detachably connected to the output piston 41 of the drive cylinder 4. When the input end of the transmission assembly is in transmission connection with the output piston 41 of the drive cylinder 4, the drive cylinder 4 can drive the linkage rod 3 to move up and down through the transmission assembly to control the opening and closing of the blade 2. At this time, the transmission assembly is in an electrically operated state. When the input end of the transmission assembly is disconnected from the output piston 41 of the drive cylinder 4, the drive cylinder 4 cannot open or close the blade 2. At this time, the operator can open or close the blade 2 through the emergency handle 5. At this time, the transmission assembly is in a manually operated state.

[0033] The driving cylinder 4 is connected to an external gas source via a gas line 11, which delivers high-pressure gas to the driving cylinder 4. A rotary valve 6 is provided on the gas line 11. This manual valve 6 controls the state of the gas path between the gas line 11 and the driving cylinder 4. When the rotary valve 6 is rotated to the de-gassing state, the gas path between the gas line 11 and the driving cylinder 4 is closed, depriving the driving cylinder 4 of high-pressure gas. At this point, the driving cylinder 4 controls the blade 2 to close via the transmission assembly. When the rotary valve 6 is rotated to the ventilation state, the gas path between the gas line 11 and the driving cylinder 4 is opened, and the high-pressure gas controls the movement of the output piston 41 of the driving cylinder 4. At this point, the driving cylinder 4 controls the blade 2 to open via the transmission assembly. In this embodiment, the rotary valve 6 is a manual, two-position, three-way valve.

[0034] There are two states between the driving cylinder 4 and the transmission assembly: connected and disconnected. When the driving cylinder 4 is working normally, the driving cylinder 4 is connected to the transmission assembly. The driving cylinder 4 can be controlled to lose air or be ventilated by the rotary valve 6 to close or open the blade 2. When the driving cylinder 4 fails and cannot work, the driving cylinder 4 can be disconnected from the transmission assembly, and the operator drives the transmission assembly through the emergency handle 5, and then manually opens or closes the blade 2 through the linkage rod 3, ensuring that the shutter can still be opened when the shutter fails and the cylinder loses air.

[0035] Preferably, the transmission assembly includes a crank arm 12 and an articulated seat 13, one end of the crank arm 12 is hinged to the linkage pull rod 3, and the other end is hinged to the articulated seat 13, one end of the emergency handle 5 is fixedly connected to the drive shaft 14, and the articulated seat 13 is fixedly assembled on the drive shaft 14; the output piston 41 is provided with a connecting piece that is detachably connected to the articulated seat 13, when the connecting piece is connected to the articulated seat 13, the transmission assembly is in an electric operation state, and when the connecting piece is disconnected from the articulated seat 13, the transmission assembly is in a manual operation state.

[0036] The transmission assembly is formed by a crank arm 12 and an articulated seat 13. The articulated seat 13 is directly fixed to the drive shaft 14 connected to the emergency handle 5. This simplifies the connection between the transmission assembly and the emergency handle 5 and ensures that the transmission assembly remains connected to the emergency handle 5. The output piston 41 is detachably connected to the articulated seat 13 via a connector. When the connector is connected to the articulated seat 13, the transmission assembly is in an electrically operated state. The output piston 41 can drive the articulated seat 13 to rotate about the drive shaft 14, thereby driving the linkage rod 3 to move via the crank arm 12. The output piston 41, articulated seat 13, crank arm 12, and linkage rod 3 form a four-bar linkage 18 structure. When the output piston 41 moves up and down, it can drive the linkage rod 3 to move along a fixed trajectory, thereby achieving automatic opening and closing of the blade 2.

[0037] In this embodiment, the articulated seat 13 is welded to the drive shaft 14 of the emergency handle 5. When the connector is disconnected from the drive shaft 14, the articulated seat 13, the crank arm 12, the linkage rod 3, and the blade 2 form a four-bar linkage 18 mechanism. The emergency handle 5 drives the articulated seat 13 to rotate via the drive shaft 14, thereby controlling the linkage rod 3 to move along a fixed trajectory, thereby achieving manual opening and closing of the blade 2.

[0038] Preferably, a socket 133 is provided on the articulated seat 13, and a parallel and spaced fixed plate 42 is fixedly assembled on the output piston 41. The drive shaft 14 is rotatably assembled on the fixed plate 42. The fixed plate 42 is spaced apart in the up and down directions with a first fixing hole 421 and a second fixing hole 422. The first fixing hole 421 is coaxially arranged with the socket 133. When the connecting piece is inserted into the first fixing hole 421 and the socket 133, the output piston 41 is transmission-connected to the articulated seat 13. When the connecting piece is inserted into the second fixing hole 422, the output piston 41 is disconnected from the articulated seat 13.

[0039] The connecting piece is connected to the socket 133, the first fixing hole 421 or the second fixing hole 422 by plugging, thereby realizing the transmission connection or disconnection between the articulated seat 13 and the output piston 41, simplifying the connection form of the connecting piece and facilitating the operator to quickly disconnect the connection between the articulated seat 13 and the output piston 41 when manual operation is required.

[0040] The second fixing hole 422 can be used to insert the connecting piece when the blade 2 needs to be manually operated, so as to temporarily store the connecting piece and avoid the connecting piece from being lost.

[0041] Preferably, the connecting member is a positioning pin 15 , and a pull ring 151 is provided at the end of the positioning pin 15 .

[0042] The positioning pin 15 forms a connecting piece, which simplifies the structure of the connecting piece, and the pull ring 151 makes it easier for operators to insert and remove the positioning pin 15. In other embodiments, the connecting piece can also be a bolt and a nut.

[0043] Preferably, the articulated seat 13 includes two parallel and spaced articulated plates 131 and a hinge shaft 132 rotatably assembled on the two articulated plates 131, the bottom end of the articulated plate 131 is welded and fixed to the drive shaft 14, the bottom end of the crank arm 12 is rotatably assembled to the articulated shaft 132, and the socket 133 is set on the articulated plate 131.

[0044] The hinge seat 13 adopts the structure of the hinge plate 131 and the hinge shaft 132, which simplifies the form of the hinge seat 13. At the same time, the hinge plate 131 provides space for the setting of the jack 133, which simplifies the layout structure of the jack 133 and the connection between the connecting piece and the hinge seat 13.

[0045] Preferably, two linkage rods 3 are arranged in parallel at intervals along the horizontal direction, a transmission rod 16 is connected between the two linkage rods 3, a support arm 17 is vertically fixed on the transmission rod 16, and the transmission assembly is in transmission connection with the support arm 17.

[0046] The two linkage rods 3 are arranged in parallel and spaced apart, and are connected by a transmission rod 16. This expands the tension-bearing surface, balances the tension between the linkage rods 3 and the blades 2, reduces the force on the contact point, and prevents deformation of the blades 2 caused by excessive force. A support arm 17 is provided on the transmission rod 16 and is connected to the transmission assembly through the support arm 17. A single drive cylinder 4 controls the synchronous movement of the two linkage rods 3, preventing deformation and damage caused by uneven force on the two linkage rods 3, while also reducing the number of drive cylinders 4.

[0047] Preferably, a connecting rod 18 is vertically arranged on each blade 2, and the linkage rod 3 is rotatably assembled with each connecting rod 18.

[0048] A connecting rod 18 is vertically arranged on the blade 2. The connecting rod 18 provides a gap between the linkage rod 3 and the blade 2, provides space for the rotation of the blade 2, and ensures that the linkage rod 3 drives the blade 2 to open and close.

[0049] Preferably, a detachable drain pipe 19 is further arranged at the bottom of the window frame 1 , and the top end of the detachable drain pipe 19 is communicated with the inner wall of the window frame 1 .

[0050] The provision of the drainage pipe 19 ensures that rainwater is promptly drained away or collected in the corresponding storage compartment, preventing rainwater from flowing into the compartment or accumulating water in the window frame 1. In this embodiment, there are two drainage pipes 19, which are welded and fixed to the bottom of the window frame 1, thereby improving drainage efficiency and preventing water from accumulating due to the uneven bottom of the window frame 1.

[0051] Preferably, a protective net 20 is further arranged on the window frame 1 , and the protective net 20 is arranged on a side away from the bulkhead 21 when the blade 2 is assembled on the hull.

[0052] The protective net 20 can prevent mice, birds and the like from entering between the blades 2 and affecting the rotation of the blades 2, and also prevent them from entering the interior of the cabin.

[0053] Preferably, a warning sign is also arranged on the emergency handle 5 .

[0054] Since the emergency handle 5 is always connected to the transmission assembly, the blinds can be opened and closed by the emergency handle 5 only when the transmission assembly is in manual operation state. Therefore, setting a warning sign can remind the operator that manual operation is only possible when the driving cylinder 4 loses air, reducing safety hazards.

[0055] In summary, an embodiment of the present invention provides a marine pneumatic remote-controlled shutter device, in which the linkage pull rod of the driving blades is connected to the emergency handle through a transmission assembly, and the driving cylinder and the transmission assembly have two states: connected and disconnected. When the driving cylinder is working normally, the driving cylinder is connected to the transmission assembly, and the driving cylinder can be controlled by a rotary valve to lose air or ventilate to close or open the blades. When the driving cylinder fails and cannot work, the driving cylinder can be disconnected from the transmission assembly, and the operator drives the transmission assembly through the emergency handle, and then manually opens or closes the blades through the linkage pull rod, ensuring that the shutter can still be opened when the shutter fails and the cylinder loses air.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
