  As a conventional sluice door lift opening and closing device, for example, a pin rack is connected to the upper part of the door body, a pinion that engages with the pin rack is provided, and a handle that rotates the pinion to open and close the door body is provided (patent Document 1) is well known.

  In order to automate the opening and closing operation of the sluice door, for example, a portable electric mechanism that engages with a manual handle of the sluice door is provided. The portable electric mechanism includes a gantry and an electric motor mounted on the gantry. In order to open and close the gate, an engaging portion attached to the electric motor is engaged with the manual handle, and the manual handle is rotated by the electric motor (see Patent Document 2). Thereby, opening and closing of the sluice door is motorized. The sluice door that is manually opened and closed can be motorized to simplify the operation of opening and closing the sluice gate in an emergency (see Patent Document 2).

  However, the sluice using the above portable electric mechanism is used temporarily, and cannot always be managed and controlled. Therefore, it cannot be automatically and appropriately operated when necessary, such as during a night flood. In addition, since the apparatus is easily increased in size and a place for storing the portable electric mechanism is required, it is difficult to configure the apparatus at a low cost.

Hereinafter, the example of the raising / lowering opening / closing apparatus of the sluice door which concerns on this invention is demonstrated in detail based on an accompanying drawing (FIGS. 1-5).
This sluice door lifting and lowering opening and closing device can be manually lifted and lowered by turning the input shaft 13 by using a handle 15 that can be attached to and detached from the input shaft 13. A speed reduction mechanism 12 is provided.

Reference numeral 20 denotes an extended input shaft, which is provided so as to be connected and extended in series via the joint portion 20a to the shaft connecting portion 13a of the input shaft 13 to which the handle 15 can be attached.
As shown in FIG. 1, the joint portion 20 a of the present embodiment has a shape that is externally fitted to the input shaft 13, and is capable of integrally connecting and fixing the extended input shaft 20 to the input shaft 13 by tightening a bolt. It has become. The connection structure is not limited to this, and other known methods such as a connection structure including a keyway and a key and a coupling structure can be used.

Reference numeral 21 denotes a bearing portion of the extended input shaft. In this embodiment, the handle is provided on the opposite side of the joint portion 20a side of the extended input shaft 20 so as to be stable by taking a large span between the parts where the bearing is made.

As the electric motor 31 of this embodiment, for example, a DC24V, 100W rated output can be used to open and close a 2.8m wide sluice door. In addition, since it decelerates by the power reduction device part 30, the speed | rate which concerns on raising / lowering opening / closing of a sluice door becomes slow, for example about 5 to 15 minutes. However, compared with the case where an operator goes to the site and performs manually, the operation can be performed quickly, surely and efficiently.

The power source of the electric motor 31 of this embodiment is a battery 41 that is charged by the solar cell 40 (see FIG. 3). The battery 41 is built in the operation panel 55, and since the power consumption of the electric motor 31 is small, the battery 41 may be relatively small.

In this embodiment, the end of the extended input shaft 20 on the side opposite to the joint 20a is the shaft connecting portion 20b to the handle.
According to this, manual operation can be performed in an emergency or the like. Since the shaft connecting portion 20b of the present embodiment is stored so as to be protected by the cover 23, the cover 23 may be opened and the handle 15 may be attached to perform the rotation operation.

Furthermore, in this embodiment, the power reduction device 30 is fixed to the inner surface of the wall 22a of the casing 22 to which the bearing 21 of the extended input shaft is fixed.
According to this, the unitized power reduction device 30 can be easily installed by the casing 22 to the lifting mechanism 12 that is part of the main body of the lifting door opening / closing device of the sluice door.
