Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a marine ventilation grille. Background Art

[0002] Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements. The operating environment of ships is relatively humid. Ventilation holes are opened in the crew lounge for ventilation to prevent mold in the lounge due to the humid environment. Grilles are set in the ventilation holes to adjust the ventilation volume.

[0003] After searching, in the prior art, the utility model with the publication number CN217198614U discloses a ventilation grille for ships, including a ventilation frame, the interior of which is provided with ventilation holes; a main baffle, located in the ventilation hole, the main baffle has an inner cavity, and both sides of the main baffle are provided with rectangular openings connected to the inner cavity; two auxiliary baffles, connected to the main baffle, and the auxiliary baffles are inserted through the rectangular openings; a rotating cylinder, rotatably connected to the ventilation frame, one end of the rotating cylinder extends to the ventilation hole and is fixedly connected to the main baffle; a rotating shaft, inserted through the inner hole of the rotating cylinder, one end of the rotating shaft extends to the inner cavity and is provided with a driving component, the driving component is used to extend or retract the two auxiliary baffles; a locking assembly, connected to the outer wall of the ventilation frame, the locking assembly is used to lock the rotating cylinder and the rotating shaft. When the air volume is small, the rotating shaft drives the two auxiliary baffles to retract into the inner cavity of the main baffle through the driving component, and the retracted length is set according to the air volume requirement; when the air volume is large, the two auxiliary baffles retract into the inner cavity, and the main baffle rotates to obtain the maximum air volume. This method can effectively adjust the ventilation volume according to needs through the coordinated use of auxiliary baffles and main baffles, but this method still has the following shortcomings: when the external wind is strong, the pressure on the auxiliary baffles and the main baffles is relatively large, which can easily cause damage to the structure and reduce the practicality of the device.

[0004] The prior art, publication number CN218967169U, is a marine ventilation grille. This method is provided with multiple closing plates, which can disperse the airflow, thereby reducing the pressure caused by the wind on the closing plates and extending the service life of the device. However, this method still has the disadvantage of poor sealing. When the device is closed, the external airflow may still pass through the gap between the two closing plates. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1-8The utility model provides a technical solution: a marine ventilation grille, comprising a bottom box 1, a rotating rod 2 is arranged at the bottom of the inner cavity of the bottom box 1, one end of the rotating rod 2 is connected to a brake block 3, the other end of the rotating rod 2 is connected to a gear 4, a top plate 7 is arranged on the top of the bottom box 1, a plurality of through holes 8 are penetrated through the top of the top plate 7, an inner cavity of the through hole 8 is sleeved with a shaft rod 6, one end of the shaft rod 6 is connected to a baffle 9, a frame body 10 is arranged on the top of the top plate 7, a plurality of fixing rods 11 are arranged in the inner cavity of the frame body 10, and limiting plates 12 are arranged on both sides of the fixing rods 11.

[0026] The two limiting plates 12 and the fixing rod 11 are arranged in a Z shape.

[0027] In this embodiment, refer to Figure 1 , five When the device is closed, the baffle 9 and the fixing rod 11 are at the same horizontal line, and one side of the baffle 9 is in contact with one side of the limiting plate 12 to close the gap between the two baffles 9 to prevent external airflow from entering through the gap, thereby improving the practicality of the device.

[0028] There are five gears 4 in total, and the multiple gears 4 are on the same horizontal line. The outer rings of the multiple gears 4 are collectively sleeved with a toothed belt 5 , and the diameters of the multiple gears 4 gradually decrease from the middle to both sides.

[0029] In this embodiment, refer to Figure 2 , three 4. When the device needs to be opened, the staff rotates the rotating rod 2 through the brake block 3, and drives the gear 4 to rotate through the rotating rod 2. When the gear 4 rotates, the shaft 6 set on the top can drive the baffle 9 to rotate, thereby opening the device and allowing air to pass through, so as to facilitate ventilation of the ship.

[0030] Reference Figure 6 The toothed belt 5 is in an elliptical shape on the outer ring of the plurality of gears 4, so that there is sufficient tension between the toothed belt 5 and the gears 4, so that the plurality of gears 4 can be linked to each other through the toothed belt 5, so as to open or close the plurality of baffles 9 at the same time, thereby improving the ease of use of the device.

[0031] A sealing gasket 13 is glued to one side of the limiting plate 12 , and the sealing gasket 13 is made of rubber.

[0032] In this embodiment, the sealing gasket 13 can prevent a gap from existing between the baffle plate 9 and the limiting plate 12, thereby further improving the sealing effect of the device.

[0033] Among them, the outer ring of the brake block 3 is provided with a plurality of slots 14, and a fixing block 15 is provided at the bottom of the bottom box 1. A screw hole 16 is penetrated at one end of the fixing block 15, and a screw rod 17 is threadedly connected to the inner cavity of the screw hole 16. A rotating block 18 is connected to one end of the screw rod 17, and a push rod 19 is rotatably connected to the other end of the screw 17. A clamping block 20 is connected to one end of the push rod 19, and the clamping block 20 is movably engaged with the slot 14.

[0034] In this embodiment, after the adjustment of the baffle 9 is completed, the staff rotates the screw 17 through the turning block 18. At this time, the through-hole thread of the screw 17 moves axially in the inner cavity of the screw hole 16 and pushes the push rod 19. At this time, the push rod 19 can push the block 20 into the inner cavity of the slot 14, thereby locking the position of the brake block 3 to prevent the baffle 9 from shaking, making the use of the device more stable.

[0035] The device uses manual adjustment to limit the brake block 3, which is safer and will not cause the device to be unable to close due to damage to electrical equipment. At the same time, the production cost of the device is low, and it is suitable for popularization and use.

[0036] The outer ring of the push rod 19 is provided with a connecting plate 21 , one side of the connecting plate 21 is connected with a plurality of limiting rods 22 , and limiting grooves 23 are also provided on both sides of the screw hole 16 , and the limiting rods 22 move in the inner cavity of the limiting grooves 23 .

[0037] In this embodiment, when the screw rod 17 pushes the push rod 19, the push rod 19 drives the connecting plate 21 to move, and the connecting plate 21 drives the limiting rod 22 to move in the inner cavity of the limiting groove 23, thereby limiting the push rod 19 to prevent the push rod 19 from rotating, thereby ensuring that the clamping block 20 can be accurately clamped in the inner cavity of the clamping groove 14.
