Description

Technical Field

[0001] The present invention relates to the technical field of blinds, and specifically to a blind for a pneumatic waterproof gun device on a ship. Background Art

[0002] A polar blind is a window system designed specifically for extreme climates. Its unique ventilation design is to meet the special needs of cold regions such as the polar regions. The blade design of the blind allows users to adjust light and ventilation as needed while maintaining privacy.

[0003] In a polar environment, ships face extreme climatic conditions, including low temperatures, strong winds, ice and snow, etc. Traditional blind designs often struggle to maintain good performance and reliability in such an environment. Secondly, the blind may be frozen in the cold environment during use, and the surface of traditional blinds is also relatively cold to the touch. Then, traditional blinds may not be very flexible and fast when opening. Also, when the ship is being cleaned, water may seep into the ship through old-fashioned blinds. Therefore, we have developed a blind for a pneumatic waterproof gun device on a ship to solve the above problems. Summary of the Invention

[0044] Working principle: First, press the hollow piston 17 with your hand, then pull the pull rod 19. Then, the pull rod 19 pulls the diamond-shaped block 25 through the steel rope 26 to contract. Then, take out the hollow piston 17. After that, pour water into the hollow frame 1 from the water inlet 3. Then, insert the hollow piston 17 into the water inlet 3, and the diamond-shaped block 25 will be squeezed into the cross-shaped chute 18. When the hollow piston 17 is inserted, the diamond-shaped block 25 will push the diamond-shaped block 25 to reset through the fourth return spring 29 and clamp the inner wall of the hollow frame 1. After that, turn on the heating plate 4 to heat the water. After heating for a period of time, the hot air will be introduced into the hollow louver 7 from the hollow rotating rod 6. Then, the air pressure will push the arc-shaped scraper 10 to expand to both sides. At this time, the air pressure will also be introduced into the L-shaped air blocking plate 30 and the pressure-bearing pipe 33 through the partition of the L-shaped partition plate 5. Then, the air pressure will push the circular piston 35 to move backward. When the air pressure reaches a certain pressure, the circular piston 35 will move to the place where the exhaust pipe 42 is connected to the pressure-bearing pipe 33 for pressure relief. Then, slide the switch block 61 above, which will drive the three-headed support rod 43. The three-headed support rod 43 will drive the movable block 41 and the silica gel baffle 40 to open the closed exhaust hole 37. Then, the air pressure will push the square piston 46 from the air supply square pipe 44. At this time, when the pressure slightly decreases, the arc-shaped scraper 10 will bounce back and slide inward slightly to squeeze the air pressure, and then assist the air pressure to push the square piston 46. Then, the square piston 46 drives the rack 47. After that, the rack 47 will push the large gear 57 to rotate. Then, the large gear 57 drives the fourth belt pulley 58 to rotate through the third rotating shaft 56. Then, the fourth belt pulley 58 drives the third belt pulley 55, the second bevel gear 54, and the second rotating shaft 53 to rotate through the fourth belt 59. After that, the second bevel gear 54 drives the first bevel gear 52 to rotate. Then, the first bevel gear 52 drives the second belt pulley 50 to rotate through the first rotating shaft 49. Then, the second belt pulley 50 drives the fourth belt pulley 58 to rotate through the first belt 51. Then, the first belt pulley 48 drives the hollow rotating rod 6. Then, the hollow rotating rod 6 drives the closed hollow louver 7 to open. Then, when the louver has been open for a period of time, slide the switch block 61 above in the reverse direction. Then, the switch block 61 drives the three-headed support rod 43, the movable block 41, and the silica gel baffle 40 to close the exhaust hole 37. Then, the mirror-image structure on the other side will open. Repeat some of the above steps to close the hollow louver 7. When not using air pressure to open and close the louver, you can slide the switch block 61 below. Then, the switch block 61 drives the transmission rod 60, and the transmission rod 60 drives the rack 47 to open and close the device, completing the work.
