Description

Technical Field

[0001] This utility model belongs to the field of ventilation grille technology, and specifically relates to a ventilation grille for ships. Background Technology

[0002] Marine ventilation grilles are key components installed at the air inlets and outlets of a ship's ventilation system. Their core function is to ensure air circulation while effectively controlling the airflow entering or leaving the ship and intercepting external debris, thus providing protection for the safety of the ship's internal environment.

[0003] For example, Chinese patent CN218967169U discloses a ventilation grille for ships, including a closed frame, a control base plate, a light-transmitting plate, a rotating shaft, and a sealing plate. The closed frame is located on top of the control base plate, the rotating shaft is evenly distributed and rotates within the closed frame, and the lower end of the rotating shaft is rotated within the control base plate. The sealing plate is symmetrically located on both sides of the rotating shaft, and the light-transmitting plate is symmetrically located on both sides of the rotating shaft and located below the sealing plate.

[0004] While the aforementioned patents have solved the problem of traditional manual adjustment for opening and closing, and the significant time required for manual closing of numerous ventilation grilles in the cargo hold, existing ventilation grilles still have some shortcomings that need improvement. Specifically, existing ventilation grilles need to be replaced after a period of use. During the replacement process, the vents are completely exposed, making it impossible to intercept external debris. This debris can easily enter the ventilation ducts or even the cargo hold, posing a safety hazard to ship operations. Furthermore, existing ventilation grilles are mostly fixed with screws, making disassembly and replacement very troublesome. Special tools are required forcibly disassembling them, extending the replacement operation time. Utility Model Content

[0023] Example

[0024] refer to Figures 1 to 6 This embodiment describes a marine ventilation grille, comprising an assembly frame 1. The assembly frame 1 has two assembly slots 2, each containing a power assembly 8. A mounting base 4 is slidably connected to the assembly slot 2 via the power assembly 8. Slots 5 are provided on both sides of the bottom of the mounting base 4. Inserts 6 are inserted into the slots 5, and positioning holes are provided in the inserts 6. A ventilation grille body 3 is fixedly connected to one side of the inserts 6. A positioning assembly 7 is provided between the ventilation grille body 3 and the mounting base 4. The dual assembly slots 2 design provides independent movement space for the mounting base 4, allowing it to be installed on both the active and backup ventilation grille bodies 3. Replacement does not expose the ventilation openings directly. The insertion and engagement of the inserts 6 and slots 5 enables quick connection between the ventilation grille body 3 and the mounting base 4, reducing the cumbersome initial installation steps compared to traditional screw fixing.

[0025] refer to Figure 4-5The positioning component 7 includes a first slide groove 74, which is formed on both sides inside the mounting base 4. A slider 72 is slidably connected inside the first slide groove 74. A positioning rod 71 is fixedly connected to one side of the slider 72. One side of the positioning rod 71 is movably connected to the insert block 6. A spring 73 is fixedly connected between the slider 72 and the first slide groove 74. A guide groove 77 is formed on one side inside the first slide groove 74. A guide block 75 is slidably connected inside the guide groove 77. One side of the guide block 75 is fixedly connected to one side of the slider 72. A push block 76 is fixedly connected to the top of the guide block 75. The push block 76 is slidably connected inside the first slide groove 74. By setting the positioning component 7, when it is necessary to disassemble the ventilation grille body 3, the push block 76 is pushed, which drives the guide block 75 to slide in the guide groove 77. The guide block 75 drives the slider 72 to move in the first slide groove 74. The slider 72 drives the positioning rod 71 to move, so that the positioning rod 71 leaves the positioning hole of the insert 6. At this time, the insert 6 is no longer fixed to the slot 5, which releases the restriction on the ventilation grille body 3. No tools are needed, which simplifies the loading and unloading process of the ventilation grille body 3. Since the push block 76 also slides in the first slide groove 74, the push block 76 can be hidden and does not affect the extension and retraction of the mounting base 4 in the assembly groove 2. It should be noted that the push blocks 76 on both sides of the mounting base 4 are located on the outside, which is convenient for the staff to operate.

[0026] refer to Figure 2-3 The power assembly 8 includes a second slide groove 83, which is located inside one side of the assembly groove 2. A motor 81 is fixedly connected inside the second slide groove 83, and a lead screw 82 is fixedly connected to the output end of the motor 81. The lead screw 82 is rotatably connected inside the second slide groove 83, and a screw block 84 is threadedly connected to the outer surface of the lead screw 82. One side of the screw block 84 is fixedly connected to one side of the mounting base 4. By setting up the power assembly 8, the output end of the motor 81 drives the lead screw 82 to rotate inside the second slide groove 83. Under the rotational force of the lead screw 82, the screw block 84, which is threadedly connected to the lead screw 82, slides along the second slide groove 83. The screw block 84 drives the mounting base 4 to move synchronously within the assembly groove 2, thus providing power for the movement of the ventilation grille body 3 without the need for manual movement, saving manpower and time.

[0027] refer to Figure 3 The second slide groove 83 has limit grooves 9 on both sides inside. Limit blocks 10 are slidably connected inside the limit grooves 9. One side of the limit block 10 is fixedly connected to one side of the screw block 84. By setting the limit grooves 9 and the limit blocks 10, when the screw block 84 slides in the second slide groove 83, the limit blocks 10 on both sides slide synchronously in the limit grooves 9, so that the screw block 84 drives the mounting base 4 to move stably.

[0028] refer to Figure 1Both sides of the assembly frame 1 are fixedly connected to fixing blocks 11, and fixing holes 12 are opened inside the fixing blocks 11. By setting the fixing blocks 11 and fixing holes 12, the assembly frame 1 is connected to the surrounding structure of the ship's ventilation opening using fasteners such as bolts, so that the entire ventilation grille device is firmly installed on the ship.

[0029] Operating principle and advantages: When the ventilation grille body 3 needs to be replaced, the power components 8 on both sides are activated. The motor 81 drives the lead screw 82 to rotate, causing the screw block 84 to move the spare ventilation grille body 3, blocking the ventilation opening. During this process, the limit block 10 slides in the limit groove 9, causing the screw block 84 to move the mounting base 4 stably. After the ventilation grille body 3 blocks the ventilation opening, the staff disassembles the ventilation grille body 3 to be replaced. The push block 76 corresponding to the ventilation grille body 3 to be replaced is pushed in the opposite direction, allowing the positioning rod 71 to disengage from the positioning hole of the insert block 6. The insert block 6 is then pulled out to complete the disassembly. The new ventilation grille body 3 is then inserted into the slot 5 through the insert block 6. The push block 76 is pushed to fix the positioning rod 71. After the replacement is completed, the power component 8 can adjust the position of the mounting base 4 as needed to store it in the assembly slot 2. In summary, the ventilation opening is always blocked by the ventilation grille body 3 during replacement, preventing debris from entering the ventilation duct and cargo hold, reducing the risk of equipment damage and navigation failure. Moreover, the installation and removal of the ventilation grille body 3 can be completed without tools, simplifying the process and improving maintenance efficiency.
