Description

Technical Field

[0001] The invention relates to the technical field of marine windows, in particular to a marine pneumatic shutter with an anti-impact mechanism. Background Art

[0002] Marine pneumatic shutters are window devices installed on ships that use a pneumatic control system to open and close the shutters. Marine pneumatic shutters are generally made of lightweight, corrosion-resistant materials such as aluminum alloy or stainless steel. They have good sealing properties and can effectively isolate external wind, sand, rain and noise.

[0003] The invention of the existing publication number CN109665064B discloses a pneumatic shutter that can resist shock waves, including a window frame. A long connecting rod driven by a cylinder can drive a short connecting rod to rotate, causing the shutter to open and close. When the shutter is closed, the close contact between the filler and the shutter can achieve a seal. When the shutter is impacted by a shock wave, the filler and the tension spring can buffer the external impact force, preventing the shutter from deforming or even breaking. This not only increases the service life but also improves the safety during use. The above solution achieves shock buffering caused by the external environment by arranging fillers and springs at the joint position of the shutter. However, when the ship shutter is in use, in addition to being subject to impact caused by external environmental factors, it is easy to open and close too quickly when pushed by the pneumatic cylinder. At this time, the shutter will open quickly or close heavily, and then the shutter will deform during the impact, and finally there will be serious problems of air and light leakage. In addition, after long-term use, the pollutants adhered to the surface of the ship shutter are not easy to be handled by itself, making it inconvenient to use. Summary of the Invention

The side where the synchronous control frame 4 and the cylinder telescopic rod 5 are close to each other is provided with a protruding connecting ear. A control arm 6 is provided between the two connecting ears through a movably connected pin shaft. When the cylinder telescopic rod 5 rises, the synchronous control frame 4 can be controlled to rise by the control arm 6. At this time, since the movable shutter 2 is connected to the ship shutter frame 1 through a rotating shaft, the movable shutter 2 is movably connected to the synchronous control frame 4 through an arc-shaped push plate 3. At this time, the movable shutter 2 is pulled to a closed state by the rising synchronous control frame 4. Several movable shutters 2 and arc-shaped push plates 3 can support the synchronous control frame 4, and then cooperate with the cylinder telescopic rod 5 to support and stabilize the synchronous control frame 4. When the movable shutter 2 needs to be opened, it can be achieved by controlling the cylinder telescopic rod 5 to descend in the same way.

The upper and lower ends of the anti-collision control box 7 are respectively provided with buffer springs 10, and when several movable shutters 2 are in the closed state, the blocking push plate 9 runs to the upper end of the air cavity of the anti-collision control box 7 and squeezes and contacts the buffer spring 10 located above; when the cylinder of the cylinder telescopic rod 5 has a gas pressure delivery failure or the switching valve is damaged, the cylinder telescopic rod 5 starts and stops quickly, the cylinder telescopic rod 5 drives the buffer support rod 8 to move quickly in the air cavity of the anti-collision control box 7, and collides with the buffer spring 10 when it is about to reach the upper and lower maximum limits. At this time, the elastic supporting force of the buffer spring 10 can unload the force and buffer the buffer spring 10, thereby avoiding impact damage caused by the cylinder telescopic rod 5 exceeding the limit of up and down movement.

[0038] Embodiment 2: On the basis of embodiment 1, gas buffering and surface treatment are performed on the closing of the movable shutter 2, and an abutment platform 27 is provided at the upper end of the air cavity of the anti-collision control box 7, and a first air delivery groove 17 and a second air delivery groove 33 are respectively provided in the abutment platform 27.

When the blocking push plate 9 abuts the lower end of the abutment platform 27, the blocking piston 29 is pushed and lifted by the piston groove 28, and the second gas delivery groove 33 will be connected to the air cavity of the anti-collision control box 7.

[0039] The upper end of the anti-collision control box 7 is connected to the second air conveying groove 33 and is provided with a branch-shaped negative pressure tee 32. The branch-shaped negative pressure tee 32 is divided into a horizontal section and an inclined section. The inclined section of the branch-shaped negative pressure tee 32 is connected to the second air conveying groove 33, and the two ends of the horizontal section of the branch-shaped negative pressure tee 32 are respectively connected with a second conveying hose 34 and a cleaning liquid pipe 35. When the blocking piston 29 is lifted to the maximum extent, the first air conveying groove 17 is blocked. At this time, the high-pressure airflow quickly enters the branch-shaped negative pressure tee 32 from the second air conveying groove 33, and then under the action of the airflow guided by the inclined section of the branch-shaped negative pressure tee 32, the airflow passes through the horizontal section at high speed and flows in the forward direction. At this time, if the cleaning liquid pipe 35 is connected to the container of the cleaning solution, the cleaning solution will be negatively pressurized by the airflow passing through the branch-shaped negative pressure tee 32 at high speed, and then enter the second conveying hose 34 together with the airflow.

[0040] A pin connecting groove is provided on one side of the synchronous control frame 4, and the arc-shaped pushing plates 3 of several movable shutters 2 are respectively inserted into the pin connecting grooves through pin shafts.

A drainage threaded plug can be provided at the lower end of the second transfer groove 12 for discharging residual cleaning agent or clean water in the second transfer groove 12. During normal use, automatic drying can be achieved by continuously supplying airflow.

[0041] The overlapping groove 19 is opened on one side of the upper end of the movable shutter 2, and the lower end of the upper movable shutter 2 is inserted into the overlapping groove 19.

A plurality of buffer air holes 21 are opened in the first diverter groove 13 and connected to the overlapping groove 19. A first transfer groove 36 is opened on one side of the first diverter groove 13 through the arc-shaped push plate 3. One end of the first transfer groove 36 is connected to the first transfer groove 11 and a first transfer hose 15 is provided. When the high-pressure airflow sent by the first delivery hose 18 into the first transfer groove 11 enters the first diverter groove 13 of the plurality of movable shutters 2 through the first transfer hose 15 When the high-pressure airflow is blown out from the buffer air hole 21, the buffer support rod 8 controls the sealing push plate 9 to rise and approach the abutment platform 27, and the upper movable shutter 2 flips toward the lower movable shutter 2. When the blocking push plate 9 is about to block the first air conveying groove 17, the movable shutter 2 is about to fit the side wall of the overlapping groove 19. At this time, the high-pressure airflow blown out by the buffer air hole 21 will form a buffer zone between the two movable shutters 2. When the blocking push plate 9 blocks the first air conveying groove 17, the movable shutter 2 just overlaps the groove 19 at the upper end of the movable shutter 2 inserted below, avoiding deformation and damage caused by collision and impact of the two movable shutters 2, and the overlapping sealing effect is better.

[0042] An assembly groove is provided at the lower end of the movable louver 2 for inserting into the overlapping groove 19, and a cleaning combination plate 22 is inserted into the assembly groove by screws. A covering sealing gasket 23 is provided on one side of the cleaning combination plate 22 that fits against the inner wall of the overlapping groove 19. A second diverter groove 14 is provided on the side of the movable louver 2 close to the cleaning combination plate 22, and a second adapter groove 37 is provided in the second diverter groove 14 through the arc-shaped push plate 3. One side of the second adapter groove 37 is connected to the second transfer groove 12 and is provided with a second adapter hose 16.

[0043] When the high-speed airflow passes through the second transfer slot 12 and the second transfer hose 16 and enters the second diversion slot 14, the high-speed airflow is blown to the surface of the movable louver 2 below through a number of cleaning nozzles 25 to clean the floating dust. When the high-pressure airflow blown in is a high-pressure gas-liquid mixture with a cleaning liquid, the stubborn stains on the surface of the movable louver 2 can be automatically cleaned. The movable louver 2 located at the top can be provided with a number of holes similar to the cleaning nozzles 25 on the side of the ship shutter frame 1 close to the movable louver 2, which can be connected to the second transfer slot 12 of the synchronous control frame 4 through a common hose to achieve the same cleaning effect.
