Abstract
Description
Technical Field
[0001] This utility model relates to the field of offshore wind power, and in particular to a high-resistance air leakage prevention door. Background Technology
[0002] Offshore wind power faces challenges from the marine environment, such as waves, salt spray, and temperature fluctuations. Offshore wind power systems contain many critical electrical and control systems. To protect these systems from salt spray and moisture, high-resistance chambers are used to ensure a dry and clean internal environment, thereby improving equipment reliability and lifespan.
[0003] However, most existing high-pressure chamber leak-proof doors use rotary valves, which are prone to gaps on the side when closed. These gaps can lead to gas leakage from the high-pressure chamber, reducing gas purity and safety. The gaps also cause pressure drops, affecting the internal pressure of the high-pressure chamber and potentially preventing the system from maintaining the required operating conditions. Furthermore, the gas loss from the gaps increases system energy consumption, reduces efficiency, and poses safety hazards. Therefore, we propose a high-pressure chamber leak-proof air-face door to solve these problems. Utility Model Content
[0004] This utility model provides a leak-proof air door for high-pressure chambers, which solves the problem that existing valves are prone to gaps on the side when closed. These gaps may cause gas to leak out of the high-pressure chamber, leading to a decrease in pressure and making it impossible for the system to maintain the required operating conditions. The gaps also cause gas loss, increasing system energy consumption, reducing efficiency, and potentially posing safety hazards.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-pressure chamber air leakage prevention door, including a door wall, sliding rails at both ends of the door wall, a sliding door frame on the door wall, a first guide rod and a second guide rod at the top and bottom of the door frame, a sealing door that can be opened and closed on one side of the door frame, the first guide rod sliding against the sliding rail, the door frame being connected by multiple first guide rods and second guide rods, and a driving mechanism on the door frame.
[0006] In the preferred embodiment, the door wall has a housing, one side of the housing has a side groove, the door wall has a door groove, and the door frame abuts against the door groove.
[0007] In a preferred embodiment, the drive mechanism includes a rotating wheel with a rotating shaft on it. One end of the rotating shaft has a main gear, the main gear has a meshing driven gear, and the driven gear has a lead screw.
[0008] In the preferred embodiment, the lead screw is connected to the door frame, and the rotating shaft is rotatably connected to the door wall.
[0009] In the preferred embodiment, guide rails are provided at both ends of the door and wall, and roller grooves are provided on the guide rails.
[0010] In the preferred embodiment, the slide rail is provided with an L-shaped groove, and the corners of the L-shaped groove are rounded.
[0011] In the preferred embodiment, multiple rollers are provided at both ends of the door frame, the rollers abut against the roller grooves, the door frame is provided with threaded holes, the lead screw is connected to the threaded holes, and the door frame is provided with multiple second rotating seats.
[0012] In a preferred embodiment, the first guide rod includes a connecting rod, one end of which is provided with a rotating shaft, and the other end of which is provided with a rotating hole. One end of the rotating shaft is provided with a second roller, the rotating hole is connected to a second rotating seat, the rotating shaft is connected to the rotating seat, and the second roller slides against the L-shaped groove.
[0013] In a preferred embodiment, the structure of the second guide rod is the same as that of the first guide rod, and the second guide rod is provided with a second roller.
[0014] The beneficial effects of this invention are as follows: When the sealing door is to be closed, the manual rotation of the drive mechanism's wheel causes the main gear to rotate, which in turn causes the driven gear to rotate, which in turn causes the lead screw to rotate, causing the door frame to slide against the guide rail. Driven by multiple second guide rods, the sealing door slides against the guide rail. When the first guide rod slides to the end of the L-shaped groove, the second roller of the first guide rod turns within the L-shaped groove. The door frame continues to move horizontally relative to the door wall, causing the sealing door to move perpendicular to the door groove. The sealing door presses against the door groove and closes tightly. Compared to a rotating closing design, closing the sealing door perpendicular to the door groove typically achieves smaller gaps or no gaps. This is because the vertical closing method can apply pressure more evenly, effectively fitting the door groove and reducing gaps generated during opening and closing, thereby improving the sealing effect.
[0015] The overall structure is simple to operate, and the sealing door is easy and quick to open and close. The overall structure effectively avoids the formation of gaps, preventing the leakage of gas from the high-pressure chamber, which could reduce gas purity and safety, affect the internal pressure of the high-pressure chamber, and cause the system to be unable to maintain the required operating conditions. Gas loss can also increase system energy consumption and reduce efficiency, making it of great value for promotion. Attached Figure Description

[0026] Example 1:
[0027] like Figure 1-8 The high-pressure chamber air leakage prevention door includes a door wall 1, with slide rails 6 at both ends of the door wall 1, and a sliding door frame 4 on the door wall 1. The top and bottom of the door frame 4 are provided with a first guide rod 7 and a second guide rod 8. A sealing door 3 that can be opened and closed is provided on one side of the door frame 4. The first guide rod 7 slides against the slide rail 6. The door frame 4 is connected by multiple first guide rods 7 and second guide rods 8. A drive mechanism 2 is provided on the door frame 4. With this structure, when the sealing door 3 is to be closed, the manual rotation of the drive mechanism 2's rotating wheel 201 causes the main gear 202 to rotate, which in turn causes the driven gear 203 to rotate, which in turn causes the lead screw 204 to rotate, causing the door frame 4 to slide against the guide rail 5. Driven by multiple second guide rods 8, the sealing door 3 slides against the slide rail 6. When the first guide rod 7 slides to the end of the L-shaped groove 601, the second roller 704 of the first guide rod 7 turns within the L-shaped groove 601. The door frame 4 remains horizontal relative to the door wall 1, causing the sealing door 3 to move perpendicular to the door groove 103. The sealing door 3 presses against the door groove 103 and closes tightly. Compared to a rotating closing design, the vertical closing of the sealing door 3 relative to the door groove 103 typically achieves smaller gaps or no gaps. This is because the vertical closing method can apply pressure more evenly, effectively fitting the door groove 103 and reducing gaps generated during opening and closing, thereby improving the sealing effect.
[0028] The overall structure is simple to operate, and the sealing door 3 is easy and quick to open and close. The overall structure effectively avoids the generation of gaps, preventing the possibility of gas leakage from the high-pressure chamber, which could reduce gas purity and safety; affect the internal pressure of the high-pressure chamber, causing the system to be unable to maintain the required operating conditions; and cause gas loss, increasing system energy consumption and reducing efficiency.
[0029] In the preferred embodiment, the door wall 1 is provided with a housing 101, a side groove 102 is provided on one side of the housing 101, and a door groove 103 is provided on the door wall 1, with the door frame 4 abutting against the door groove 103. With this structure, the housing 101 can effectively protect the drive mechanism 2, guide rail 5, and slide rail 6, while preventing workers from bumping into the drive mechanism 2, guide rail 5, or slide rail 6 when passing through the door groove 103, thus avoiding injuries.
[0030] In a preferred embodiment, the drive mechanism 2 includes a rotating wheel 201, on which a rotating shaft 205 is mounted. A main gear 202 is mounted at one end of the rotating shaft 205, and a meshing driven gear 203 is mounted on the main gear 202. A lead screw 204 is mounted on the driven gear 203. With this structure, manually rotating the rotating wheel 201 of the drive mechanism 2 causes the main gear 202 to rotate, which in turn causes the driven gear 203 to rotate, which in turn causes the lead screw 204 to rotate. This causes the door frame 4 to slide against the guide rail 5. Driven by multiple second guide rods 8, the sealing door 3 slides against the slide rail 6, allowing the sealing door 3 to open and close.
[0031] In the preferred embodiment, the lead screw 204 is connected to the door frame 4, and the rotating shaft 205 is rotatably connected to the door wall 1. With this structure, the rotating wheel 201 of the drive mechanism 2 can be manually rotated to make the door frame 4 slide against the guide rail 5.
[0032] In the preferred embodiment, guide rails 5 are provided at both ends of the door frame 1, and roller grooves 501 are provided on the guide rails 5. With this structure, multiple rollers 401 at both ends of the door frame 4 slide against the roller grooves 501.
[0033] In a preferred embodiment, the slide rail 6 is provided with an L-shaped groove 601, and the corner of the L-shaped groove 601 is provided with a rounded corner 602. With this structure, the second roller 704 of the first guide rod 7 slides against the L-shaped groove 601. The rounded corner 602 at the corner of the L-shaped groove 601 facilitates the turning of the second roller 704. When the second roller 704 moves to the rounded corner 602 in the L-shaped groove 601, the turning of the second roller 704 causes the door frame 4 to transition from horizontal movement to vertical movement relative to the door wall 1.
[0034] In a preferred embodiment, the door frame 4 has multiple rollers 401 at both ends, with the rollers 401 abutting against roller grooves 501. The door frame 4 has threaded holes 402, and the lead screw 204 is connected to the threaded holes 402. The door frame 4 also has multiple second rotating seats 403. This structure drives the drive mechanism 2 to rotate the lead screw 204, thereby causing the door frame 4 to move horizontally.
[0035] In a preferred embodiment, the first guide rod 7 includes a connecting rod 701. One end of the connecting rod 701 has a rotating shaft 702, and the other end has a rotating hole 703. One end of the rotating shaft 702 has a second roller 704. The rotating hole 703 is connected to the second rotating seat 403, and the rotating shaft 702 is connected to the rotating seat 301. The second roller 704 slides against the L-shaped groove 601. With this structure, one end of the first guide rod 7 is rotatably connected to the door frame 4, and the other end of the first guide rod 7 is rotatably connected to the sealing door 3. At the same time, the second roller 704 of the first guide rod 7 slides against the L-shaped groove 601.
[0036] In a preferred embodiment, the structure of the second guide rod 8 is the same as that of the first guide rod 7, and the second guide rod 8 is equipped with a second roller. With this structure, one end of the second guide rod 8 is rotatably connected to the door frame 4, and the other end of the second guide rod 8 is rotatably connected to the sealing door 3. The second guide rod 8 is equipped with the second roller structure.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
