Description

Technical Field

[0001] The present invention relates to the technical field of marine windows, and particularly to a pneumatic louver for ships with an anti-impact mechanism. Background Art

[0002] A marine pneumatic louver is a window device installed on a ship that uses a pneumatic control system to achieve the opening and closing functions of the louvers. Marine pneumatic louvers are generally made of lightweight and corrosion-resistant materials such as aluminum alloy or stainless steel, and have good sealing performance, which can effectively isolate external sand, rain, and noise; The invention with the publication number CN109665064B discloses a pneumatic louver that can resist shock waves, including a window frame. Driving a long connecting rod through a cylinder can drive a short connecting rod to rotate, prompting the louver board to open and close. When the louver board is closed, it can be sealed through the close contact between the packing and the louver board. When the louver board is impacted by a shock wave, the external impact force can be buffered through the action of the packing and the tension spring, avoiding the phenomenon that the louver board is deformed or even broken. This not only improves the service life but also improves the safety during use. The above solution realizes the impact buffering caused by the external environment by setting packing and springs at the louver joint position. However, when a marine louver is in use, in addition to being possibly impacted by external environmental factors, when it is pushed by a pneumatic cylinder, it is prone to open and close too quickly. At this time, the louvers will quickly open or close heavily, and then the louver boards will be deformed during the impact process, and finally there will be serious problems of air leakage and light leakage. Moreover, after a marine louver has been used for a long time, the pollutants adhering to its surface are not easy to be processed by itself, and it is inconvenient to use. Summary of the Invention

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to the attached Figure 1-14 , and the present application provides the following technical solutions.

[0018] Embodiment 1: A pneumatic louver for ships with an anti-impact mechanism, comprising a ship louver frame 1 and a control assembly. A plurality of movable louvers 2 are movably arranged on one side of the ship louver frame 1 through a rotating shaft. The plurality of movable louvers 2 are arranged in sequence from top to bottom. The lower end of the movable louver 2 located above overlaps one side of the movable louver 2 located below. The control assembly includes two synchronous control frames 4 and two cylinder telescopic rods 5. Two arc-shaped push plates 3 are symmetrically arranged on one side of each movable louver 2. The two arc-shaped push plates 3 of the plurality of movable louvers 2 are respectively connected to the two synchronous control frames 4 through pin shafts. The synchronous control frame 4 is movably connected to the cylinder telescopic rod 5. Two extension plates are horizontally arranged on one side of the lower end of the ship louver frame 1. Cylinders are arranged at the upper ends of the two extension plates. The cylinder telescopic rod 5 is vertically movably arranged at the upper end of the cylinder. The two synchronous control frames 4 are correspondingly arranged with the two cylinder telescopic rods 5. Connecting ears are provided on the sides of the synchronous control frame 4 and the cylinder telescopic rod 5 that are close to each other. A control arm 6 is movably connected between the two connecting ears through a pin shaft. When the cylinder telescopic rod 5 rises, the synchronous control frame 4 can be lifted through the control arm 6. At this time, since the movable louver 2 is connected to the ship louver frame 1 through a rotating shaft and the movable louver 2 is movably connected to the synchronous control frame 4 through the arc-shaped push plate 3, the movable louver 2 is pulled to the closed state by the rising synchronous control frame 4 at this time. The plurality of movable louvers 2 and the arc-shaped push plates 3 can support the synchronous control frame 4, and thus the support stability of the synchronous control frame 4 can be coordinated with the cylinder telescopic rod 5. When it is necessary to open the movable louver 2, it can be achieved by controlling the cylinder telescopic rod 5 to descend in the same way.

[0019] A buffer component is provided to buffer the possible rapid telescopic movement of the cylinder telescopic rod 5. The buffer component is arranged at the upper end of the cylinder telescopic rod 5. The buffer component includes an anti-impulse control box 7 and a buffer support rod 8. The buffer support rod 8 is vertically arranged above the cylinder telescopic rod 5. The upper end of the buffer support rod 8 is movably and hermetically inserted into the anti-impulse control box 7. The upper end of the anti-impulse control box 7 is respectively connected and provided with a first delivery hose 18 and a bifurcated negative pressure tee 32. The upper and lower ends of the movable louver 2 are respectively provided with an overlapping groove 19 and a cleaning combination plate 22. And the first delivery hose 18 and the bifurcated negative pressure tee 32 are respectively communicated with the overlapping groove 19 and the cleaning combination plate 22. The anti-impulse control box 7 is vertically arranged at the upper end of the cylinder through a fixed support rod. An air chamber is opened in the anti-impulse control box 7. A high-pressure air joint is connected to one side of the air chamber. The upper end of the buffer support rod 8 is inserted into the air chamber of the anti-impulse control box 7 and is provided with a plugging and pushing plate 9. Buffer springs 10 are respectively arranged at the upper and lower ends in the anti-impulse control box 7. And when a number of movable louvers 2 are in a closed state, the plugging and pushing plate 9 runs to the upper end in the air chamber of the anti-impulse control box 7 and squeezes and contacts the buffer spring 10 located above; when there is a gas pressure delivery failure in the cylinder of the cylinder telescopic rod 5 or the switching valve is damaged and other situations where 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 chamber of the anti-impulse control box 7. When approaching the upper and lower maximum limits, it collides with the buffer spring 10. At this time, the elastic supporting force of the buffer spring 10 can unload the force of the buffer spring 10 to avoid impact damage caused by the excessive up and down movement of the cylinder telescopic rod 5.

[0021] The upper end of the anti-collision control box 7 is connected to the second gas 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 gas 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 gas conveying groove 17 is blocked. At this time, the high-pressure airflow quickly enters the branch-shaped negative pressure tee 32 from the second gas 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 a container of cleaning solution, the cleaning solution will be negatively pressure-lifted 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.

[0022] On one side inside the synchronous control frame 4, a pin connection groove is provided. The arc-shaped push plates 3 of several movable louvers 2 are respectively inserted into the pin connection groove through pins. On the side of the synchronous control frame 4 away from the movable louvers 2, a first transfer groove 11 and a second transfer groove 12 are vertically provided. One end of the first delivery hose 18 is communicated with the first transfer groove 11, and one end of the second delivery hose 34 is communicated with the second transfer groove 12. Both the first transfer groove 11 and the second transfer groove 12 can be filled with clean high-pressure gas. Clean water can enter the second transfer groove 12 along with the airflow. A drain screw plug can be provided at the lower end of the second transfer groove 12 for discharging the remaining cleaning agent or clean water in the second transfer groove 12. During normal use, automatic drying can be achieved by continuously sending in airflow.

[0023] An overlapping groove 19 is provided on one side of the upper end of the movable louver 2. The lower end of the upper movable louver 2 is inserted into the overlapping groove 19.

On one side of the first diversion groove 13, a first transfer groove 36 is provided through the arc-shaped push plate 3. One end of the first transfer groove 36 and the first transfer groove 11 are both communicated with a first transfer hose 15. When the high-pressure air flow sent into the first transfer groove 11 by the first delivery hose 18 enters the first diversion grooves 13 of several movable louvers 2 through the first transfer hose 15 respectively, the high-pressure air flow blows out from the buffer air holes 21. When the buffer support rod 8 controls the plugging and pushing plate 9 to rise and approach the abutment platform 27, the upper movable louver 2 turns towards the lower movable louver 2. When the plugging and pushing plate 9 is about to block the first delivery air groove 17, the movable louver 2 is about to fit against the side wall of the overlapping groove 19. At this time, the high-pressure air flow blown out from the buffer air holes 21 will form a buffer zone between the two movable louvers 2. When the plugging and pushing plate 9 blocks the first delivery air groove 17, the movable louver 2 just overlaps with the overlapping groove 19 at the upper end of the lower movable louver 2 inserted therein, avoiding deformation and damage caused by the collision and impact of the two movable louvers 2. At the same time, the overlapping has a better sealing effect.

[0024] An assembly groove is provided at the lower end of the movable louver 2 inserted into the overlapping groove 19. The cleaning combination plate 22 is inserted into the assembly groove by screws. A covering gasket 23 is attached to one side of the cleaning combination plate 22 that fits against the inner side wall of the overlapping groove 19. A second diversion groove 14 is provided on one side of the movable louver 2 close to the cleaning combination plate 22. A second transfer groove 37 is provided through the arc-shaped push plate 3 in the second diversion groove 14. A second transfer hose 16 is provided in communication with the second transfer groove 37 on one side and the second transfer groove 12.

A cleaning spray groove 25 is provided through the communication connectors 24 and the overlapping groove 19 in the cleaning combination plate 22. One side of the cleaning spray groove 25 passing through the overlapping groove 19 is located outside the overlapping groove 19, and one end of the cleaning spray groove 25 passing through the overlapping groove 19 is inclined to point to the surface of the movable louver 2 below; When the high-speed air flow enters the second diversion groove 14 through the second transfer groove 12 and the second transfer hose 16, the high-speed air flow blows towards the surface of the movable louver 2 below through a plurality of cleaning spray grooves 25 to clean the floating dust. When the blown high-pressure air flow is a high-pressure gas-liquid mixture with cleaning liquid, the surface of the movable louver 2 can be automatically cleaned of stubborn stains. For the movable louver 2 at the uppermost position, a plurality of holes similar to the cleaning spray grooves 25 can be provided on one side of the ship louver window frame 1 close to the movable louver 2 and connected to the second transfer groove 12 of the synchronous control frame 4 through a common hose to achieve the same cleaning effect.
