Description

Technical Field

[0001] This utility model relates to the field of underwater operations, specifically to a push-pull underwater opening and closing door. Background Technology

[0002] With the increasing prevalence of underwater operations, the deployment of related equipment underwater is also becoming more frequent. Therefore, the requirements for the safety and stability of underwater doors are becoming increasingly stringent. The underwater environment has two main characteristics: high water pressure and a large amount of debris. Currently, doors are commonly classified by their opening and closing methods, including sliding doors and hinged doors. Hinged doors are difficult to open under high underwater pressure and occupy too much space, making them unusable. Sliding doors, on the other hand, are space-saving and easy to open, but they suffer from poor sealing. Utility Model Content

[0003] The main objective of this invention is to provide a push-pull underwater door to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a door frame, a sliding door panel on the back side of the door frame, a door opening on one side of the door frame, and a fixed seat fixed on the other side, and the fixed seat and the door panel are connected by a pushing mechanism.

[0005] A sliding groove is fixed on the outer side of the door frame, and the two sides of the door panel move against the sliding groove;

[0006] The door panel is equipped with a sliding connecting frame, and a swing hydraulic cylinder is fixed on the connecting frame. The swing hydraulic cylinder is connected to the door panel through a rotating rod and is used to push the door panel to move and abut against the door opening.

[0007] Preferably, the pushing mechanism is a hydraulic cylinder, with the piston rod end of the pushing mechanism fixedly connected to the connecting frame, and the cylinder end fixed on the fixed seat.

[0008] Preferably, multiple sleeves are fixed at the bottom of the connecting frame, and multiple guide shafts are fixed on the door panel accordingly, with the guide shafts sliding against the sleeves.

[0009] Preferably, a vertical rod is fixedly provided on the door panel, and a sliding sleeve is provided on the vertical rod. One end of the rotating rod is fixedly connected to the output screw of the swing hydraulic cylinder, and the other end is hinged to the sliding sleeve.

[0010] Preferably, the bottom of the swing hydraulic cylinder is provided with a hinged rotating rod, and the end of the rotating rod is hinged to the sliding sleeve.

[0011] This utility model provides a push-pull underwater door, with the following advantages:

[0012] 1. By combining the jacking mechanism with the swing hydraulic cylinder, precise movement and clamping of the door panel are achieved, ensuring that the door panel accurately covers the door opening. The sliding fit between the sliding sleeve and the vertical rod allows the system to better adapt to any minor deviations that may exist between the door panel and the door opening, improving the reliability of closing and sealing performance.

[0013] 2. The sleeve at the bottom of the connecting frame and the guide shaft on the door panel ensure the stability of the door panel during movement, reducing the risk of offset or tilting, while also reducing friction and extending the service life of the equipment. The sliding fit reduces direct friction between components, helping to slow down the wear of mechanical parts and improve the durability of the system.

[0014] 3. Precise door panel positioning and clamping ensure a good seal, preventing water leakage and enhancing the safety of underwater facilities. The hydraulic system not only provides powerful driving force but also prevents excessive pressure through precise pressure control, protecting the door panel and surrounding structure from damage.

[0022] like Figures 1-5 As shown, a push-pull underwater door includes a door frame 1, a sliding door panel 5 on the back of the door frame 1, a door opening on one side of the door frame 1, and a fixed seat 2 fixed on the other side. The fixed seat 2 and the door panel 5 are connected by a push mechanism 4.

[0023] A sliding groove 3 is fixedly provided on the outer side of the door frame 1, and the two sides of the door panel 5 move against the sliding groove 3;

[0024] The door panel 5 is provided with a sliding connecting frame 6, and a swing hydraulic cylinder 9 is fixed on the connecting frame 6. The swing hydraulic cylinder 9 is connected to the door panel 5 through a rotating rod 7 and is used to push the door panel 5 to move and abut against the door opening.

[0025] The push mechanism 4 can push the door panel 5 to move laterally to the door opening, and the swing hydraulic cylinder 9 can push the door panel 5 to press it firmly at the door opening, thereby realizing opening and closing.

[0026] The door frame 1 is the framework structure of the entire device, providing the path and boundaries for the door panel to move. The door panel is the part that actually performs the closing action, and can slide within the door frame to close or open the doorway. The pushing mechanism 4 is responsible for pushing the door panel laterally from its initial position to the doorway, achieving the initial positioning of the door panel.

[0027] The fixed base 2 provides a fixed connection point for the jacking mechanism, ensuring the stability and efficiency of force transmission. The slide 3 is installed on the outside of the door frame, providing guidance for the movement of the door panel and ensuring that the door panel can move smoothly along the predetermined path.

[0028] The connecting bracket supports the swing hydraulic cylinder and allows for necessary adjustments relative to the door panel. The swing hydraulic cylinder is connected to the door panel via a rotating rod 7. When the hydraulic cylinder operates, it can change the angle or position of the door panel via the rotating rod, thereby fitting more tightly against the edge of the door opening and ensuring a good seal.

[0029] Operating principle: First, the pushing mechanism moves the door panel horizontally to the front of the door opening; then, the swing hydraulic cylinder is activated, pressing the door panel firmly against the door opening to complete the closing action.

[0030] Preferably, the pushing mechanism 4 is a hydraulic cylinder, the piston rod end of the pushing mechanism 4 is fixedly connected to the connecting frame 6, and the cylinder end is fixed on the fixed seat 2.

[0031] The hydraulic cylinder uses the pressure of internal hydraulic oil to push the piston rod to extend or retract, thereby achieving lateral movement of the door panel 5. The end of the piston rod is fixedly connected to the connecting frame 6. When the hydraulic cylinder operates, the force it generates acts directly on the connecting frame, thus causing the door panel to move horizontally. This connection method ensures the directness and efficiency of force transmission. The cylinder end is fixed to the fixed base 2, providing a stable support point for the hydraulic cylinder, ensuring that the hydraulic cylinder does not undergo unnecessary displacement during operation, while distributing the reaction force to a more robust structural component.

[0032] Preferably, the bottom of the connecting frame 6 is fixed with multiple sleeves, and multiple guide shafts 10 are fixed on the door panel 5 respectively, and the guide shafts 10 slide against the sleeves.

[0033] The guide shaft 10 is fixed to the door panel 5 and inserted into the sleeve of the connecting bracket 6, allowing it to slide within the sleeve. The door panel 5 is moved by the swing hydraulic cylinder 9 and the rotating rod 7, and the guide shaft 10 abuts against the sleeve to ensure smooth and reliable sliding.

[0034] Preferably, a vertical rod 8 is fixedly provided on the door panel 5, and a sliding sleeve 11 is provided on the vertical rod 8. One end of the rotating rod 7 is fixedly connected to the output screw of the swing hydraulic cylinder 9, and the other end is hinged to the sliding sleeve 11.

[0035] The swing hydraulic cylinder 9 drives the rotating rod 7 to rotate, thereby causing the sliding sleeve 11 to slide against the vertical rod 8, which in turn pushes the door panel 5 to move and press it against the door opening.

[0036] The vertical rod 8 is fixed to the door panel 5, providing a sliding path for the sliding sleeve 11 and serving as a support structure for force transmission. The sliding sleeve 11 is mounted on the vertical rod 8 and can slide up and down along the vertical rod. It is hinged to one end of the rotating rod 7, allowing the rotating rod to have a certain angular change relative to the vertical rod.

[0037] One end of the rotating rod 7 is fixedly connected to the output screw of the swing hydraulic cylinder 9, and the other end is hinged to the sliding sleeve 11. When the swing hydraulic cylinder is driven, the rotating rod will rotate around its connection point with the hydraulic cylinder, thereby causing the sliding sleeve to slide along the vertical rod.

[0038] Operating Procedure: The jacking mechanism 4 first moves the door panel 5 horizontally to the position in front of the doorway. Next, the swing hydraulic cylinder 9 is activated, and its output screw rotates, causing the rotating rod 7 to swing. The swing of the rotating rod drives the sliding sleeve 11 to slide along the vertical rod 8, thereby pushing the door panel 5 towards the doorway. Finally, the door panel is pressed tightly against the doorway, ensuring a sealing effect.

[0039] Preferably, the bottom of the cylinder of the swing hydraulic cylinder 9 is provided with a hinged rotating rod 7, and the end of the rotating rod 7 is hinged to the sliding sleeve 11. This ensures the stability of the swing hydraulic cylinder 9 during operation, and makes the overall structure more stable.

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.
