Description

Technical Field

[0001] The utility model relates to the technical field of ship ventilation devices, and more specifically, the utility model relates to a simple automatic opening and closing device for the inlet of a cabin fan. Background Art

[0002] During the navigation of a ship, in order to ensure the air flow inside the cabin, it is necessary to carry out air exchange through a fan, so as to increase the oxygen concentration, reduce the high temperature and high humidity inside the cabin, and provide a comfortable working environment for the staff.

[0003] The inlet of the fan in the ship's engine room is an important part of the engine room ventilation system, which is mainly responsible for introducing fresh air from the outside into the engine room. The existing inlets of fans mostly use multi-blade movable shutters with closable blades to control the opening and closing state of the fan inlet. Although this method can achieve the purpose of controlling the opening and closing of the fan inlet, the multi-blade movable shutter has a high failure rate. Once one of the blades is not closed in place, the closing of the fan inlet will lose its effect. Moreover, the state of the blades of the multi-blade movable shutter during opening and closing is very unintuitive and very inconvenient to use. Therefore, it needs to be improved.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The utility model achieves the function of closing the box body by setting a closing plate, a rotating rod, a rotating shaft and a round rod. Since the closing plate completely covers the front of the box body, when it is necessary to open the closing plate, the air cylinder can be started to pull the connecting plate to move, so that the inner surface of the moving frame squeezes and pushes the round rod to move along the inner surface of the sliding groove.

Due to the design of the filter plate, it can filter dust and sundries in the air to prevent them from entering the interior of the engine room. The operator can rotate the rotating block to release the support and fixation of the installation frame. At this time, the installation frame will move downward under the action of gravity, so that the clamping block contacts the bottom of the inner surface of the box body and stops moving downward, thus releasing the fixation of the filter plate. When the filter plate is removed from the interior of the box body, the operator can take down the filter plate for replacement or cleaning, which facilitates the installation and disassembly of the operator.

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.

[0028] like Figures 1 to 5 As shown, the utility model provides a simple automatic opening and closing device for the inlet of a cabin fan, comprising:

[0029] The air duct 1 has a box 2 fixedly mounted on the top thereof, and hinged rods 3 are hingedly connected to the left and right sides of the box 2, and a closing plate 4 is hingedly connected to the other end of the hinged rod 3, and the outer surface of the closing plate 4 is movably connected to the front of the box 2, and rotating rods 5 are hingedly connected to the top of the left and right sides of the closing plate 4, and a rotating shaft 6 is fixedly sleeved inside the top of the rotating rod 5, and support blocks 7 are movably sleeved on the left and right sides of the outer surface of the rotating shaft 6, and the bottom of the support block 7 is fixedly connected to the top of the box 2;

[0030] An opening and closing mechanism is arranged on the top of the box body 2;

[0031] Among them, the opening and closing mechanism includes a support frame 8, which is fixedly installed on the top of the box body 2, and a fixed block 9 is fixedly installed on the rear side of the inner surface of the support frame 8. A slide groove 10 is opened inside the fixed block 9, and a round rod 11 is movably sleeved inside the slide groove 10. A connecting rod 12 is movably sleeved on the outer surface of the round rod 11. The outer surface of the connecting rod 12 is movably connected to the inner wall of the fixed block 9, and the inner part of the bottom end of the connecting rod 12 is fixedly sleeved with the outer surface of the rotating shaft 6. The rotation of the connecting rod 12 will drive the rotating shaft 6 to rotate;

[0032] The driving mechanism is arranged on the top of the inner surface of the supporting frame 8.

[0033] When the round rod 11 moves along the inner surface of the slide groove 10, it will drive the connecting rod 12 to rotate, so that the connecting rod 12 drives the rotating shaft 6 to rotate, and then the rotating shaft 6 can drive the rotating rod 5 to rotate upward with the rotating shaft 6 as the axis. At this time, the rotating rod 5 cooperates with the hinged rod 3, so that the rotating rod 5 can drive the closing plate 4 to move upward, thereby releasing the closure of the box body 2.

[0034] The driving mechanism includes:

[0035] A pneumatic cylinder 13, the outer surface of the pneumatic cylinder 13 is fixedly connected to the top of the inner surface of the support frame 8;

[0036] The connecting plate 14 has its outer surface fixedly connected to the rear end of the pneumatic cylinder 13. The outer surface of the connecting plate 14 is respectively movably connected to the inner surface of the support frame 8 and the top of the fixed block 9. On the left and right sides of the bottom of the connecting plate 14, moving frames 15 are fixedly installed, and the inner surface of the moving frame 15 is movably connected to the outer surface of the round rod 11.

[0037] When the pneumatic cylinder 13 is started, it will pull the connecting plate 14 to move forward, so that the connecting plate 14 drives the moving frame 15 to move, and then the inner surface of the moving frame 15 squeezes and pushes the round rod 11 to move.

[0038] Among them, an installation frame 16 is movably sleeved inside the box body 2. A baffle 18 is fixedly installed inside the installation frame 16, and a filter plate 17 located in front of the baffle 18 is movably installed inside the installation frame 16.

[0039] By setting the filter plate 17, the filter plate 17 can filter the external dust and sundries, preventing these dust and sundries from entering the interior of the engine room.

[0040] Among them, a limiting groove 19 is opened at the top of the front surface of the installation frame 16, and a limiting block 20 is movably installed inside the limiting groove 19.

[0041] The inner surface of the limiting groove 19 is smooth, so that the limiting block 20 can move more smoothly.

[0042] Among them, a clamping block 21 is fixedly connected to the front surface of the limiting block 20, and the outer surface of the clamping block 21 is movably connected to the outer surface of the filter plate 17.

[0043] By setting the clamping block 21, the clamping block 21 can fix the filter plate 17, preventing the filter plate 17 from falling off the inside of the installation frame 16.

[0044] Among them, on the left and right sides of the top of the clamping block 21, springs 22 are fixedly installed, and the top of the springs 22 is fixedly installed with a mounting plate 23, and the back surface of the mounting plate 23 is fixedly connected to the front surface of the installation frame 16.

[0045] By setting the springs 22, the springs 22 can push the clamping block 21 to reset downward under the action of elastic force recovery.

[0046] Among them, a round block 24 is fixedly installed at the bottom of the box body 2, and a rotating block 25 is movably sleeved on the outer surface of the round block 24, and the upper surface of the rotating block 25 is movably connected to the bottom of the installation frame 16.

[0047] The operator can release the support and fixation of the installation frame 16 by rotating the rotating block 25.

[0048] The working principle and usage process of the present utility model:

[0049] Due to the design of the closing plate 4, the closing plate 4 can close the front of the box body 2. When the operator needs to open the closing plate 4, the pneumatic cylinder 13 is started, so that the pneumatic cylinder 13 pulls the connecting plate 14 to move, so that the connecting plate 14 can drive the moving frame 15 to move, and then the inner surface of the moving frame 15 squeezes and pushes the outer surface of the round rod 11, so that the round rod 11 moves along the inner surface of the slide groove 10, so that the round rod 11 drives the connecting rod 12 to rotate, and then the connecting rod 12 drives the rotating shaft 6 to rotate, so that the rotating shaft 6 can drive the rotating rod 5 to rotate. At this time, the rotating rod 5 will drive the closing plate 4 to move upward in cooperation with the hinged rod 3, thereby releasing the closure of the box body 2.

[0050] Due to the design of the filter plate 17, the filter plate 17 can filter dust and debris in the air. When the operator needs to clean the filter plate 17, the rotating block 25 can be rotated to release the support and fixing effect on the installation frame 16, so that the installation frame 16 moves downward under the action of gravity. When the block 21 moves downward and contacts the bottom of the inner surface of the box body 2, the block 21 will stop moving downward, thereby releasing the fixation of the filter plate 17. When the filter plate 17 moves downward away from the interior of the box body 2, the operator can take the filter plate 17 out of the interior of the installation frame 16, which is convenient for the operator to clean and replace the filter plate 17.
