However, it takes a lot of labor to manually drive the waterproof door to an operating position where it can be waterproofed, and it is difficult to use it for a large waterproof door. In addition, it was difficult to manually drive the waterproof door in response to sudden floods and floods.

On the other hand, when it is driven by a motor, it is possible to operate it at high speed even with a large waterproof door, but if the motor installation location is flooded or a power failure occurs, the motor is driven. If this is not possible, there is a risk that the waterproof door cannot be driven in operation. In addition, the introduction cost is high due to the installation of the motor, and maintenance of the motor and the like is required, and the maintenance cost is also high.
Furthermore, it is expected that it will be difficult to calmly respond to sudden floods and floods, and there has been a demand for waterproof doors that can operate reliably in an emergency with proper operation.

The present invention has been made in view of the above circumstances, and provides a waterproof door that is easy to maintain, can be operated reliably at low cost by preventing mistakes even in an emergency, and can be increased in size. It is an attempt to achieve the purpose of doing so.

The present invention has a door plate that operates and retracts between a retractable position and a waterproof operating position, and a drive mechanism that operates and retracts the door plate.
The drive mechanism is connected to the drive shaft, transmits the rotational drive force from the portable rotary drive source to the drive shaft, and switches the rotation of the drive shaft between the operation direction and the retract direction. A part is provided,
The operation evacuation operation unit includes an operation rotation connection unit that is rotatably connected to the drive shaft, and a retraction rotation connection unit that is rotatably connected to the operation rotation connection unit.
During the operation / retract operation of the door plate, one of the operation rotation connection portion and the retract rotation connection portion is selected, the portable rotation drive source is connected, and the door plate is rotated in the same direction to operate or retract. By making it operable, when operating the door plate in the evacuation position, simply select the operating rotation connection part, connect the portable rotation drive source, and rotate it in the preset direction. Then, the door plate can be set to the operating position. At this time, since it is not necessary to incorporate a drive source such as a motor into the waterproof plate as a drive mechanism, the installation cost can be reduced and the time and labor required for maintenance work can be reduced. At the same time, since the portable rotary drive source is not built into the waterproof plate, the motor will not be submerged even in the event of a sudden flood, and it will be possible to prevent problems such as inability to operate in an emergency. can. Further, in the operation evacuation operation, it is possible to perform either operation simply by selecting the operation rotation connection unit and the evacuation rotation connection unit and rotating one of them, so that the operator can perform one of the operations when responding to an emergency inundation. Even in a situation where mistakes are likely to occur due to a rush, it is possible to reliably operate the operation. Further, by setting the rotation directions required for the operation operation and the evacuation operation to be the same direction, it is possible to eliminate mistakes in driving even for an operator who is not calm.

The operation evacuation operation unit of the present invention conceals either the operation rotation connection unit or the evacuation rotation connection unit arranged close to each other, and the rotating member of the portable rotation drive source cannot be connected to the concealed side. By providing a connection switching control unit that can be switched to, the connection switching regulation unit conceals (covers) the evacuation rotation connection unit during operation, and the evacuation rotation connection unit is equipped with a rotary member of the portable rotation drive source. The connection switching control unit hides (covers) the operating rotation connection unit during the evacuation operation, so that the rotating member of the portable rotation drive source cannot be connected to this operating rotation connection unit. Can be maintained. As a result, even in a situation where an operator is rushed and a mistake is likely to occur, such as when responding to an emergency flood, it is possible to reliably prevent the occurrence of a mistake and perform an operation evacuation operation.

The operation evacuation operation unit of the present invention displays a side to which the portable rotation drive source can be connected in conjunction with switching between the operation rotation connection unit and the evacuation rotation connection unit by the connection switching regulation unit. Or by providing a concealed switching display, when the connection switching regulating unit conceals one of the operating rotation connection unit and the evacuation rotation connection unit, one of the corresponding switching displays interlocks and conceals. Will be done. As a result, when selecting either the operating operation or the evacuation operation, the side to which the rotating member of the portable rotary drive source can be connected is clearly indicated by the switching display, and the operator is in a hurry when responding to an emergency inundation. Even in a situation where mistakes are likely to occur, it is possible to reliably prevent the occurrence of mistakes and perform the operation evacuation operation.

In the present invention, in the operation evacuation operation unit,
The operating rotation connection part
An operating rotary connection gear connected to a drive gear that transmits a rotary drive force to the drive shaft,
An operating rotation connecting shaft that rotatably supports the operating rotation connection gear,
An operating rotation connection end provided at one end of the operating rotation connection shaft and capable of connecting a rotating member of the portable rotation drive source during the operating operation of the door plate.
Have,
The evacuation rotation connection part
The evacuation rotation connection gear connected to the operation rotation connection gear and
An evacuation rotation connection shaft that rotatably supports the evacuation rotation connection gear,
An evacuation rotation connection end provided at one end of the evacuation rotation connection shaft and capable of connecting the rotating member of the portable rotation drive source during the evacuation operation of the door plate.
When the door plate is driven in operation, the rotating member of the portable rotation drive source is connected to the operation rotation connection end, and the operation rotation connection end is rotated. Then, the operating rotation connection shaft provided with the operating rotation connection end rotates, and this rotational driving force is transmitted from the operating rotation connection gear connected to the operating rotation connection shaft to the drive gear, and the drive shaft connected to the drive gear. Is driven to rotate. At this time, since the retract rotation connection gear is connected to the operating rotation connection gear, the retract rotation connection shaft rotates in the opposite direction to the operating rotation connection shaft.
Similarly, when the door plate is retracted and driven, the rotating member of the portable rotation drive source is connected to the retracted rotation connection end, and the rotation connection end is rotated. Then, the retract rotation connection shaft provided with the retract rotation connection end rotates, and this rotational driving force is transmitted from the retract rotation connection gear connected to the retract rotation connection shaft to the operating rotation connection gear, and is driven from the operating rotation connection gear. The drive shaft transmitted to the gear and connected to the dynamic gear is rotationally driven. At this time, the retract rotation connection shaft is rotated in the same direction as the operation rotation connection shaft during operation drive, and the retract rotation connection shaft is rotated in the opposite direction to that during operation drive.
This makes it possible to set the rotation direction of the retract rotation connection shaft during the retract drive and the rotation direction of the operation rotation connection shaft during the operation drive in the same direction, and perform the operation retract operation.

Further, in the present invention, the connection switching restricting unit has a cover plate portion that can be moved by switching between a retracted position that covers the operating rotation connection portion and an operating position that covers the retracting rotation connection portion. A portable rotation drive source that allows a person to select either the evacuation rotation connection end or the operation rotation connection end without performing any further confirmation operation by just looking at the position of the cover plate. It is possible to determine the connecting side of the rotating member and perform either the evacuation operation or the operation operation.

Further, since the operation evacuation operation unit is provided with a rotation speed display unit that displays the integrated rotation speed in the operation rotation connection shaft from the start of the operation evacuation operation of the door plate, the operation can be performed from the retracted position to the operating position. When driving the door plate from the position to the retracted position, it is possible to accurately display the drive ratio to the end of the drive operation from the portable rotary drive source. In particular, in a large waterproof plate, the time required to complete the drive is long, such as when the portable rotation drive source is set as a low torque and high rotation speed with respect to the rotational state of the drive shaft. It is possible to recognize how much the driving force is transmitted from the portable rotary drive source, that is, the degree of achievement of the driving force transmission with respect to the end of the operation. As a result, since it is possible to predict the end of the operation, it is possible to stop the portable rotary drive source in an appropriate drive state at the end of the operation and prevent the occurrence of a problem caused by the over-rotation of the drive shaft. In addition, by being able to predict the end of operation, it is possible to accurately determine the remaining time until the end of transmission of driving force from the portable rotation drive source, that is, the end of the state in which the portable rotation drive source is connected to the operation evacuation operation unit. Can be predicted.

Further, the rotation speed display unit is provided with an operation end notice display for displaying that the integrated rotation speed of the operation rotation connection shaft to be displayed is near the end of the operation withdrawal operation of the door plate. Therefore, at the end of the operation, the portable rotary drive source can be stopped in an appropriate drive state, and it is possible to easily prevent the occurrence of a defect caused by the over-rotation of the drive shaft. In addition, since the end of operation can be predicted, the remaining time until the end of transmission of driving force from the portable rotation drive source, that is, the end of the state in which the portable rotation drive source is connected to the operation evacuation operation unit can be simplified. Can be predicted.

Further, the operating rotation connection end and the evacuation rotation connection end have the same shape, and the rotating members of the portable rotation drive source have a correspondingly connectable shape, and these are set to a concavo-convex shape. , The rotating member of the operating rotary connection end and the portable rotary drive source, and the rotary member of the retractable rotary connection end and the portable rotary drive source can be easily connected to reliably transmit the driving force. .. Further, since the operating rotation connection end and the evacuation rotation connection end have the same shape, both the operating rotation connection end and the evacuation rotation connection end can be rotated only by providing a rotating member of one portable rotation drive source. It becomes possible.
For example, the rotating member of the portable rotation drive source may be a socket of an impact wrench, and the operating rotation connection end and the retracted rotation connection end may be bolt heads having the same dimensions and a shape corresponding to the socket, or portable. It is possible to use a hexagon socket of an impact wrench as the rotating member of the rotary drive source, and to use a bolt head with a square hole having the same dimensions as the operating rotary connection end and the retracted rotary connection end and having a shape corresponding to the socket.
In addition, by using the rotating member of the portable rotary drive source as a socket for power tools, etc., even if the portable rotary drive source cannot be used, a waterproof plate can be manually used by using a socket wrench or the like, which is a corresponding shape socket. Can be driven.
Further, as long as the rotating member of the portable rotation drive source and the operating rotation connection end and the retracted rotation connection end have a shape that can be rotationally driven correspondingly, the shape is not limited to these.

In the present invention, since the portable rotary drive source is a portable electric motor, a power tool having a power source such as a motor and a secondary battery, for example, a conventional tool such as an impact wrench or an electric driver is utilized. can do.
Can be done.

Further, by providing the operation evacuation operation unit at a position not covered by the door plate in the retracted state, the portable rotary drive source can be operated without any trouble when the door plate is operated from the retracted position. It becomes possible to connect the rotating member to the operation evacuation operation unit.

According to the present invention, it is possible to provide a waterproof plate that is easy to maintain, can be operated reliably at low cost by preventing mistakes even in an emergency, and can be increased in size. Is possible.
