Description

Technical Field

[0001] This application relates to the field of airlock technology, specifically a ventilation component for a ship's engine room. Background Technology

[0002] Ventilation in a ship's engine room is often controlled by airtight dampers, which allow airflow to be controlled by opening and closing the damper gates.

[0003] Traditionally, airtight windbreak gates are fixed to mounting plates with bolts. A drive device then rotates a rotating rod, which in turn rotates the mounting plate, thus turning the gate. However, ships sail at sea for extended periods, where the air is humid, causing corrosion at the bolt connections. This results in the bolts becoming stuck when the gate is damaged and needs replacement, making replacement inconvenient.

[0004] Therefore, this application provides a ship engine room ventilation assembly to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a ship engine room ventilation component, which aims to solve the problems mentioned in the background art, such as the traditional airtight wind gate being fixedly connected to the mounting plate by bolts. However, ships sail at sea for a long time, and the sea air is humid, which causes corrosion of the bolt connection. As a result, when the gate is damaged and needs to be replaced, the bolts are rusted and difficult to replace.

[0006] To achieve the above objectives, this application provides the following technical solution: a ship engine room ventilation assembly, including a gate, an mounting plate disposed on the front of the gate for installing the gate, a rotating rod fixedly disposed on the side of the mounting plate away from the gate for driving the mounting plate to rotate, a bolt inserted through the gate and the mounting plate for fixing the gate, and a nut sleeved on one end of the bolt for fixing the bolt;

[0007] To protect the bolts and nuts: a first protective member for sealing and protecting the bolts is provided on the side of the gate away from the mounting plate, and a second protective member for protecting the nut is provided on the end of the bolt near the nut; the first protective member includes a protective plate provided on the side of the gate away from the mounting plate for protecting the bolts, a mounting groove formed on the side of the protective plate facing the gate for the bolts to move, and a first sealing ring fixedly provided on the side of the protective plate facing the gate for sealing between the protective plate and the gate. By inserting one end of the bolt into the mounting groove and fixing the bolt position with the retaining ring, multiple bolts can be connected to the mounting plate by moving the protective plate during bolt installation. Then, by rotating the nut, the bolt drives the retaining ring, continuously moving the protective plate towards the gate, thereby continuously compressing the first sealing ring and filling the gap between the protective plate and the gate. This prevents external moisture from entering the mounting groove, thus protecting the bolt with the first protective component. When the nut can no longer be rotated, the gate and the mounting plate are fixedly connected. At this point, the protective block is moved to the end of the bolt away from the first protective component, and the end of the bolt is inserted into the through slot and threadedly connected to the threaded groove. At this time, the protective block and the mounting plate work together to compress the second sealing ring, sealing the protective block and the mounting plate, and providing sealing protection for the nut. This prevents the gate from being difficult to disassemble due to corrosion of the bolt and nut.

[0008] Preferably, for positioning the bolt: the protective plate is provided with a retaining ring on the side facing the gate to restrict the movement of the bolt, and a connecting rod for fixing the retaining ring and the protective plate is fixedly connected to one side of the retaining ring. By engaging the bolt inside the retaining ring, the bolt is positioned, preventing the bolt from wobbling freely within the mounting groove.

[0009] Preferably, the vertical cross-section of the retaining ring is C-shaped.

[0010] Preferably, to facilitate the movement of the protective plate: a gripping block for facilitating the movement of the protective plate is fixedly connected to the side of the protective plate away from the gate. The protective plate can be moved by pulling the gripping block.

[0011] Preferably, to facilitate the protection of the nut: the second protective component includes a protective block sleeved on the outside of the bolt near the nut end, and a second sealing ring fixedly disposed on the end of the protective block facing the mounting plate for sealing between the protective block and the mounting plate. Through the combined action of the protective block and the mounting plate, the second sealing ring is compressed, thereby sealing the area between the protective block and the mounting plate.

[0012] Preferably, to facilitate the fixing of the protective block: a through slot is provided at one end of the protective block facing the mounting plate, and a threaded groove is provided on the inner wall of the through slot, through which the bolt is threadedly inserted. By connecting the bolt to the threaded groove, the protective block is fixedly installed, thereby protecting the bolt and the nut.

[0013] Preferably, for rotating the gate: a mounting frame for mounting the rotating rod is provided on the outside of the rotating rod, and a driving device for driving the rotating rod to rotate is provided on the top of the mounting frame. The rotating rod is driven to rotate by the driving device, causing the rotating rod to drive the mounting plate to rotate synchronously, thereby causing the mounting plate to drive the gate to rotate, thus achieving ventilation.

[0014] This application, through the design of a first and second protective component, involves inserting one end of a bolt into the mounting groove. By rotating the nut, the bolt drives the retaining ring, continuously moving the protective plate towards the gate. This continuously compresses the first sealing ring, filling the gap between the protective plate and the gate, thus preventing external moisture from entering the mounting groove. This completes the protection of the bolt by the first protective component. When the nut can no longer be rotated, the gate and mounting plate are fixedly connected. At this point, the protective block is moved to the end of the bolt away from the first protective component, and the end of the bolt is inserted into the through slot and threadedly connected to the threaded groove. At this time, the protective block and the mounting plate work together to compress the second sealing ring, sealing the space between the protective block and the mounting plate, and providing sealing protection for the nut. This prevents the gate from being difficult to disassemble due to corrosion of the bolt and nut. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a ship engine room ventilation component, such as Figure 1-6 As shown, the ventilation assembly includes a gate 1, an mounting plate 2 disposed on the front of the gate 1 for mounting the gate 1, a rotating rod 3 fixedly disposed on the side of the mounting plate 2 away from the gate 1 for driving the mounting plate 2 to rotate, a bolt 4 inserted inside the gate 1 and the mounting plate 2 for fixing the gate 1, and a nut 5 sleeved on one end of the bolt 4 for fixing the bolt 4.

[0025] To protect the bolt 4 and nut 5: a first protective member 6 for sealing and protecting the bolt 4 is provided on the side of the gate 1 away from the mounting plate 2, and a second protective member 7 for protecting the nut 5 is provided on the end of the bolt 4 near the nut 5; the first protective member 6 includes a protective plate 61 provided on the side of the gate 1 away from the mounting plate 2 for protecting the bolt 4, a mounting groove 62 opened on the side of the protective plate 61 facing the gate 1 for moving the bolt 4, and a first sealing ring 63 fixedly provided on the side of the protective plate 61 facing the gate 1 for sealing between the protective plate 61 and the gate 1. By inserting one end of the bolt 4 into the mounting groove 62 and fixing the position of the bolt 4 with the retaining ring 64, multiple bolts 4 can be inserted and connected to the mounting plate 2 together by moving the protective plate 61 during installation. Then, by rotating the nut 5, the bolt 4 drives the retaining ring 64, continuously moving the protective plate 61 towards the gate 1, thereby continuously compressing the first sealing ring 63 and filling the gap between the protective plate 61 and the gate 1. This prevents external moisture from entering the mounting groove 62, thus completing the first protection... The protective block 71 protects the bolt 4. When the nut 5 cannot be rotated, the gate 1 and the mounting plate 2 are fixedly connected. Then, the protective block 71 is moved to the end of the bolt 4 away from the first protective block 6, and the end of the bolt 4 is inserted into the through slot and threadedly connected to the threaded groove 73. At this time, the protective block 71 and the mounting plate 2 work together to squeeze the second sealing ring 72, so that the protective block 71 and the mounting plate 2 are sealed, which plays a role in sealing and protecting the nut 5, and avoids the difficulty of disassembling the gate 1 due to the corrosion of the bolt 4 and the nut 5.

[0026] Specifically, for rotating the gate 1: a mounting frame 8 is provided on the outside of the rotating rod 3 for mounting the rotating rod 3, and a driving device 9 is provided on the top of the mounting frame 8 for driving the rotating rod 3 to rotate. The rotating rod 3 is driven to rotate by the driving device 9, causing the mounting plate 2 to rotate synchronously, thereby causing the mounting plate 2 to drive the gate 1 to rotate, thus achieving ventilation. The gate 1, mounting plate 2, rotating rod 3, bolts 4, nuts 5, mounting frame 8, and driving device 9 constitute the existing airtight ventilation gate.

[0027] Specifically, for positioning the bolt 4: the protective plate 61 is provided with a retaining ring 64 on the side facing the gate 1 to restrict the movement of the bolt 4. A connecting rod 65 for fixing the retaining ring 64 and the protective plate 61 is fixedly connected to one side of the retaining ring 64. The vertical cross-section of the retaining ring 64 is C-shaped. By engaging the bolt 4 inside the retaining ring 64, the bolt 4 is positioned, preventing the bolt 4 from wobbling freely within the mounting groove 62. The retaining ring 64 is bonded and fixed to the contact part of the connecting rod 65. The connecting rod 65 is bonded and fixed to the inside of the mounting plate 2. Four mounting grooves 62 are symmetrically opened at the four corners of the protective plate 61 facing the gate 1. The retaining ring 64 is set inside the mounting groove 62. The position of the retaining ring 64 corresponds to the position of the screw hole of the mounting plate 2. The shank of the bolt 4 is engaged inside the retaining ring 64, thereby restricting the movement of the bolt 4. Thus, when installing the bolt 4, the protective plate 61 can be moved to drive multiple bolts 4 to be inserted into the screw holes of the gate 1 and the mounting plate 2 together, which facilitates the installation of multiple bolts 4. The first sealing ring 63 is annular and is bonded to the side of the protective plate 61 facing the gate 1. The mounting groove 62 is within the annular range of the first sealing ring 63.

[0028] More specifically, to facilitate the movement of the protective plate 61: a gripping block 66 is fixedly connected to the side of the protective plate 61 away from the gate 1 to facilitate its movement. The protective plate 61 can be moved by pulling the gripping block 66. The gripping block 66 is welded to the protective plate 61 at the contact point. When the protective plate 61 is fixed to the gate 1, disassembling and removing it becomes inconvenient; in this case, the protective plate 61 can be moved by removing the gripping block 66.

[0029] Specifically, to facilitate the protection of the nut 5, the second protective component 7 includes a protective block 71 sleeved on the outside of the bolt 4 near the nut 5, and a second sealing ring 72 fixedly disposed on the end of the protective block 71 facing the mounting plate 2 for sealing between the protective block 71 and the mounting plate 2. Through the combined action of the protective block 71 and the mounting plate 2, the second sealing ring 72 is compressed, thereby sealing the connection between the protective block 71 and the mounting plate 2. The threaded groove 73 is bonded and fixed to the contact portion of the protective block 71, and the protective block 71 covers and protects the bolt 4 and the nut 5.

[0030] More specifically, to facilitate the fixing of the protective block 71: the end of the protective block 71 facing the mounting plate 2 has a through slot, and the inner wall of the through slot has a threaded groove 73. The bolt 4 is threadedly inserted into the threaded groove 73. By threading the bolt 4 into the threaded groove 73, the protective block 71 is fixedly installed, thereby protecting the bolt 4 and the nut 5. The size of the through slot is 1.1 times the size of the nut 5. The inner thread of the threaded groove 73 and the outer thread of the bolt 4 mesh with each other. Thus, when installing the protective block 71, by rotating the protective block 71, the connection between the protective block 71 and the bolt 4 is achieved under the action of the threaded groove 73 and the bolt 4 meshing, until the protective block 71 can no longer be rotated. At this time, the protective block 71 will press against the second sealing ring 72 with the mounting plate 2, sealing the protective block 71 and the mounting plate 2.

[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
