Background
The side propeller is used as a special propeller of the ship, so that the operability and maneuverability of the ship can be greatly improved. However, because the side thrusters are installed and the side thrusters are required to be arranged, the streamline of the ship body is damaged due to the existence of the side thrusters, and the ship is subjected to larger ship resistance when advancing. The presence of the side-push closure device effectively solves this problem, and when the side-push is closed, the side-push closure maintains the streamlined integrity of the hull, reducing the additional drag created by the side-push barrel.
The inner side of the side pushing sealing cover device is contacted with seawater, the outer side of the side pushing sealing cover device is connected with the bottom (dry cabin) of the cabin, and a plurality of seals are required to be arranged on a shafting of the side pushing sealing cover to prevent the seawater from flowing backwards. However, no side pushing sealing cover device capable of emergency maintenance is currently seen, and once a sealing element is worn or fails, the sealing element needs to be in dock for maintenance or a temporary water collecting device can only be installed for treating leaked seawater, so that the maintenance cost and the maintenance time are greatly increased. Therefore, there is a need for innovative design of the emergency maintainability of the side-push closure.
Disclosure of Invention
The utility model aims to provide a side pushing sealing cover device capable of being maintained in an emergency way, which is used for solving the problems that when the existing side pushing sealing cover sealing element is worn or damaged, a worker cannot replace a rotary seal in time, the sealing can be replaced when waiting for a ship to dock, and a great deal of maintenance time and cost are consumed.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the utility model provides a but side push capping device of emergent maintenance, includes apron, pivot, bearing clamp plate, rotary seal spare, sealing clamp plate, bush, gasbag, bearing, be connected through the bearing between pivot seat and the pivot, the terminal surface is equipped with the bearing clamp plate, carries out rotary seal through rotary seal spare and sealing clamp plate between bearing clamp plate and the epaxial bush of pivot, rotary seal spare inboard sets up inflatable gasbag, and gasbag fixed connection is in the bearing clamp plate.
Further, the sealing pressing plate is fixedly connected to the bearing pressing plate through bolts.
Further, under normal working conditions, the air bag is in a gas leakage state, and the rotating shaft and the bearing pressing plate are sealed by two rotary seals behind the air bag to realize seawater sealing.
Further, the air bag is provided with a ventilation pipeline, and is connected with a movable air compressor or a central air source through the ventilation pipeline, and is used for inflating the air bag through the movable air compressor or the central air source.
Further, when the rotary seal fails to be maintained in an emergency, the air bag is inflated through an air compressor or a central air source and then is expanded and attached to the bushing, so that static sealing of the side pushing sealing cover is realized, seawater is prevented from penetrating into the cabin, and the rotary seal can be replaced in the cabin.
Further, the rotating shaft is connected with the cover plate through a flange, and the rotating shaft is connected with a motor or an oil cylinder and is used for driving the rotating shaft to rotate through the motor or the oil cylinder, so that the cover plate is opened and closed.
Furthermore, the bearing is a water lubrication bearing, and the axial direction is fixed through a bearing pressing plate by means of external seawater lubrication.
The beneficial effects of the utility model are as follows:
by adopting the side pushing sealing cover device capable of emergency maintenance, when the sealing element of the side pushing sealing cover is worn or damaged, the replacement of the rotary seal in the cabin can be completed in time, the docking maintenance is not needed, and the maintenance cost and time are greatly saved.
Drawings
FIG. 1 is a cross-sectional view of an emergency serviceable side push closure arrangement of the present utility model;
FIG. 2 is an enlarged view of a portion of the side-push capping device of the present utility model for emergency maintenance.
Detailed Description
The utility model will be further described with reference to the drawings and examples.
As shown in fig. 1 and 2, the side pushing cover device capable of emergency maintenance comprises a cover plate 1, a rotating shaft 2, a bearing pressing plate 3, a rotary sealing piece 4, a sealing pressing plate 5, a bolt 6, a bushing 7, an air bag 8, a bearing 9 and the like.
The rotating shaft seat of the cover plate 1 is connected with the rotating shaft 2 through a bearing 9, the end face of the cover plate is provided with a bearing pressing plate 3, and the bearing pressing plate 3 and a bushing 7 on the rotating shaft 2 are rotationally sealed through a rotary sealing piece 4 and a sealing pressing plate 5. The sealing pressing plate 5 is fixedly connected to the bearing pressing plate 3 by bolts 6. An air bag 8 is arranged on the inner side of the rotary sealing piece 4, and the air bag 8 is fixedly connected in the bearing pressing plate 3. Normally the air bag 8 is in a deflated state, and at this time the sea water seal is achieved by two rotary seals 4 behind the air bag 8. The air-bag 8 is not available for dynamic sealing of the working environment and therefore the side-pushing closure device is not drivable when the seal is replaced. The air bag 8 is provided with an air vent pipeline, and is connected with a movable air compressor or a central air source through the air vent pipeline, and the air bag 8 is inflated through the movable air compressor or the central air source.
When the rotary seal 4 fails, the worker can inflate the air bag 8 by using an air compressor or a central air source, and the air bag 8 expands and is attached to the bushing 7, so that the static seal of the side pushing seal cover is realized, and seawater is prevented from penetrating into the cabin. The rotary seal 4 can be replaced by staff in the cabin, so that docking maintenance is not needed, and maintenance cost and time are greatly saved.
When the rotary seal 4 is replaced, only the bolts 6 and the sealing pressing plates 5 are required to be detached, and a worker can replace the rotary seal 4 through a tool clamp.
The rotating shaft 2 is connected with the cover plate 1 through a flange, and the rotating shaft 2 is driven to rotate through a motor or an oil cylinder, so that the cover plate 1 is opened and closed.
The bearing 9 is a water lubrication bearing, and is lubricated by external seawater, so that the fixation in the axial direction is realized through the bearing pressing plate 3.
