Description

Technical Field

[0001] The present invention relates to the technical field of ship shutters, in particular to a pneumatic remote-controlled shutter for ship cabins. Background Art

[0002] Environmental control in ship cabins is crucial to the safe operation of ships and the comfort of personnel. Shutters, as an important part of the ship's ventilation system, are mainly used to regulate air circulation, temperature and humidity in the cabin, while preventing seawater, rainwater and other harsh external environments from entering the cabin. Traditional manual shutters have many inconveniences in operation, especially in severe sea conditions or emergencies. It is difficult for personnel to operate the shutters quickly and accurately, affecting the safety and operating efficiency of the ship; pneumatic remote-controlled shutters are remotely controlled through pneumatic actuators. Operators can open and close the shutters through the control system in the control room without having to go to the site for manual operation, which greatly improves the convenience and safety of operation.

[0003] In the prior art, there is a pneumatic shutter for ships with an anti-impact mechanism, such as publication number CN118358693A; adjacent blades are locked to adjacent support rods through the cooperation of limit members and locking members, so that all blades in the same row are combined into a whole, thereby improving the impact resistance of the blades, and using support rods to provide support for the connection between two adjacent blades, further improving the impact resistance of the blades and reducing the probability of seawater entering the cabin.

[0004] The above document improves the impact resistance of the blades by combining all the blades in the same row into a whole. However, during actual sea voyages, when encountering more extreme weather, the blades of the blinds are easily shaken and gaps are likely to appear.

[0005] Therefore, the present invention proposes a pneumatic remote-controlled blind for a ship cabin to solve the problem that when traditional blinds encounter extreme weather, gaps are easily formed between the blades due to shaking, and the deformation of the rubber strip affects the tightness between adjacent blades.

[0040] In this embodiment, the blade assembly 4 is composed of a blade back plate 41 and a curved panel 42, and a hollow structure is formed between the two. The blade back plate 41 is a whistle-shaped structure formed by an annular plate 411 and a flat plate 412. When the pneumatic adjustment mechanism controls the angles of multiple groups of blade assemblies 4 to swing synchronously to achieve closing, the rubber strips 421 provided at both ends of the curved panel 42 are adapted and embedded with the overlapping strips 422, which can block the gaps between adjacent blade assemblies 4 and implement stable closure. In addition, the curved surface design of the curved panel 42 can divert rainwater and facilitate air circulation when the shutter is in the open state, thereby improving the air quality in the cabin. air flow effect; and it should be noted that, the outside of the overlapping strips 422 is increased with reinforcing ribs 4221 arranged in a horizontal array, which is connected to the curved panel 42, so as to meet the connection between the overlapping strips 422 and the curved panel 42 while ensuring the structural strength of the curved panel 42; it is also worth noting that the addition of anti-seepage side plates 420 at both ends of the curved panel 42 can enhance the strength of the longitudinal edge of the curved panel 42. At the same time, the thickness of the anti-seepage side plates 420 is higher than the horizontal plane of the curved panel 42, which can block rainwater on the curved panel 42 to prevent it from seeping into the cabin from the side, further ensuring the effectiveness of the blade assembly 4 when it is closed.

[0041] Example 3, refer to the attached Figure 1-17On the basis of the second embodiment, in order to further tighten the adjacent blade assemblies 4 when closing and overlapping: the tightening assembly includes a gas elbow 4113, a telescopic bag tube 4114 and an elastic member. One end of the gas elbow 4113 extends to the inner cavity of the hollow shaft 43 and passes through the inner wall of the splicing strip 4111 and the adapting strip plate 4112. The other end of the gas elbow 4113 is sealed with the telescopic bag tube 4114. The end of the telescopic bag tube 4114 away from the gas elbow 4113 is fixed. The elastic member includes a balancing bar 4116 and an elastic block 4117. Two balancing bars 4116 are provided and fixedly mounted on either side of the telescopic bag tube 4114.

The central inner wall of the elastic block 4117 is provided with a U-shaped groove, and a hexagram-shaped abutment block 4118 is fixedly mounted inside the U-shaped groove.

[0042] In this embodiment, after the adjacent blade components 4 are overlapped, the rubber molding 421 is embedded in the adjacent rubber embedding groove 4220, and the suction groove 42200 is adapted to the outer side surface of the adaptation strip 4112, and the two are in close contact when overlapped. At this time, the negative pressure fan 23 is started to form a connection with the multiple sets of hollow shafts 43. At this time, the external air source sucks air into the closed space formed by the suction groove 42200 and the reserved groove 41120 through the resistance suction cup 4115, and the air between the two is extracted by the gas elbow 4113 to form a stable negative pressure environment, thereby ensuring that the overlapping surface of the blade component 4 achieves zero gap sealing under the dual effects of mechanical contact and air pressure adsorption, effectively resisting strong winds The risk of water seepage under extreme working conditions such as , rainstorm, etc.; the balance bars 4116 and elastic blocks 4117 connected on both sides of the telescopic bag tube 4114 cooperate with each other to ensure that the telescopic bag tube 4114 can recover its deformation and fix it after compression, and the hexagram-shaped block 4118 embedded in the central U-shaped groove provides two-way support for the telescopic bag tube 4114: in the vacuum compression stage, the elastic block 4117 and the hexagram-shaped block 4118 work together to limit the excessive deformation of the telescopic bag tube 4114 to prevent sealing failure; at the moment of blade closing, the combination of the telescopic bag tube 4114 and the elastic part absorbs the impact energy through elastic potential energy, weakens the rigid collision between the curved panel 42 and the splicing bar 4111, and avoids structural damage; it is worth noting that, with reference to Figure 12 As shown, the telescopic bag tube 4114 can not only form a flow channel with the gas bend tube 4113, but also cooperate with the elastic parts connected to the side to weaken the impact when the curved panel 42 and the joint strip 4111 are closed, provide an effective buffering effect, and meet the negative pressure pumping effect, with a multi-purpose effect.

[0043] Example 4, refer to the attached Figure 1-17On the basis of the third embodiment, in order to achieve the strength of the structure formed by the blade back plate 41 and the curved panel 42: a reinforcement component and a support component are provided between the curved panel 42 and the blade back plate 41, the reinforcement component includes a support frame 44, the interior of the support frame 44 is filled with sound-absorbing cotton; the support component includes a support plate 45, the support plate 45 is integrally formed by a short support plate, a long support plate and a connecting sleeve, the central inner surface of the connecting sleeve is fixedly connected to a central rod 451, the outer surfaces of the short support plate and the long support plate are respectively connected to the curved panel 42 The inner surfaces are movably in contact with each other, and a curved contact plate 452 is fixedly connected between the short plate and the long plate. The outer surface of the curved contact plate 452 is movably in contact with the inner surface of the curved panel 42. Fixed seats are provided at both ends of the center rod 451. The fixed seats are fixedly mounted on the inner surface of the flat plate 412. The inner surface of the fixed seat is rotatably connected to the outer surface of the center rod 451. A circular groove is provided on the inner surface of the fixed seat. A torsion spring 4511 is provided inside the circular groove. The torsion spring 4511 is movably sleeved on the outer side of the center rod 451.

[0044] In this embodiment, the support frame 44 distributed in a horizontal array provides support for the hollow structure formed between the blade back plate 41 and the curved panel 42. The sound-absorbing cotton filled inside not only provides structural support for the blade, but also effectively absorbs environmental noise such as wind noise and rain noise generated during the navigation of the ship, while reducing the vibration transmission of the blade caused by the impact of airflow, thereby reducing the risk of structural fatigue; the support plate 45 forms a multi-point mechanical support network through the integrated support short plate, support long plate and connecting sleeve design, in which the outer surfaces of the support short plate and the support long plate are tightly fitted with the inner surface of the curved panel 42, and the local pressure bearing capacity is further enhanced through the curved touch plate 452 connected in the middle to ensure that the blade can withstand the impact of airflow. Maintaining shape stability under complex working conditions; the center rod 451 is rotatably connected to the inner surface of the flat plate 412 through the fixing seats at both ends, and the torsion spring 4511 arranged on the inner side of the fixing seat can dynamically adjust the supporting torque, so that the blades always maintain a uniform stress state during the opening and closing process, avoiding local deformation or damage caused by stress concentration; on the one hand, the combined action of the reinforcing component and the supporting component significantly enhances the bending stiffness and impact resistance of the blade component 4, so that it can adapt to the high-intensity airflow impact under extreme sea conditions; on the other hand, the noise reduction function of the sound-absorbing cotton and the dynamic adjustment mechanism of the torsion spring 4511 jointly optimize the vibration response characteristics of the blade component 4, effectively extending the service life of the structure, while improving the comfort of the cabin environment.

[0045] Example 5, refer to the attached Figure 1-17 Based on the fourth embodiment, the present invention further proposes a method for using a pneumatic remote-controlled shutter for a ship cabin, comprising the following steps:

[0046] Step 1: By controlling the air intake system and air delivery system of the pneumatic adjustment mechanism, the adjustment support block 224 is driven to realize the longitudinal height change and angle adjustment of the blade assembly 4. When the pneumatic adjustment mechanism is running, the blade assembly 4 swings synchronously to complete the opening or closing action of the shutter, ensuring the ventilation or sealing requirements of the cabin and realizing remote automatic control; Step 2: When the blade assembly 4 is in the closed state, the rubber inserts 421 of the adjacent blades are embedded in the rubber insert grooves 4220 of the overlapping strips 422, and at the same time, the inner wall suction grooves 42200 of the overlapping strips 422 are tightly fitted with the outer side of the adapter strips 4112, and the enclosed space is evacuated through the external air source through the resistance suction cup 4115 to form a stable Negative pressure environment, ensure that the blade overlap surface achieves zero-gap sealing under the dual effects of mechanical contact and air pressure adsorption, and effectively resists the risk of water seepage under extreme working conditions such as strong winds and heavy rains; Step three, by strengthening the synergy between the components and the support components, the bending stiffness and impact resistance of the blade component 4 are improved. The sound-absorbing cotton filled inside the support frame 44 not only provides structural support, but also absorbs environmental noise such as wind noise and rain noise during the navigation of the ship, reducing vibration transmission; the support plate 45 forms a multi-point mechanical support network through the one-piece support short plate, support long plate and connecting sleeve design, ensuring that the blade maintains a stable shape under complex working conditions, optimizes the vibration response characteristics, and improves the comfort of the cabin environment.
