By operating this oil supply pump, hydraulic pressure (hydraulic oil) can be supplied to the hydraulic jack 6 through the oil supply pipe and the oil supply pipe 4. The oil supply pump includes a backflow prevention valve. When the hydraulic jack 6 is extended by hydraulic pressure (when the waterproof door body 2 is raised), the backflow prevention valve is closed and operated to prevent hydraulic oil from flowing in the direction opposite to the oil supply direction. . On the other hand, when the backflow prevention valve is opened in a state where a load is applied to the hydraulic jack 6, the hydraulic jack 6 contracts and the waterproof door body 2 descends due to the hydraulic oil flowing in a direction opposite to the oil supply direction. .

  As shown in FIGS. 3A and 3B, the waterproof door support portion 24 is provided so that the seal portion 17 does not come into contact with the floor surface TG when the waterproof door body 2 is in the fully open position. The main body 2 is supported. More specifically, as shown in FIGS. 3 (a) and 3 (b), the waterproof door support portion 24 includes a lower end beam member 15 and a base that is fixed to the floor surface TG and supports the lower surface of the lower end beam member 15. Part 16. When the waterproof door body 2 is in the fully open position, the pedestal portion 16 overlaps with the lower end girder 15 as viewed from above, so that the waterproof door body can be connected to the seal portion 17 even when the hydraulic pressure of the hydraulic jack 6 is released. The lower end girder 15 is supported so that the load of 2 is not applied. When the waterproof door body 2 rotates to the closed side to some extent from the fully open position, the pedestal portion 16 does not overlap with the lower end girder 15 as viewed from above. Therefore, when the waterproof door body 2 is in the fully closed position, the waterproof door body 2 can be lowered to a height at which the seal portion 17 comes into contact with the floor TG as shown in FIG. It has become. The pedestal portion 16 is disposed on the door front end side with respect to the center portion in the width direction of the waterproof door body 2.

  Next, the operation of the waterproof door 1 according to this embodiment will be described.

  In normal times, as shown in FIGS. 1 to 3, the waterproof door 1 is in a fully open position in the rotation direction. Further, the hydraulic pressure in the hydraulic jack 6 is released, and in this state, the lower end girder material 15 comes into contact with the upper surface of the pedestal portion 16, whereby the waterproof door body 2 is pedestal so that the seal portion 17 is separated from the floor surface TG. Supported by the portion 16.

  On the other hand, when the possibility that the inside of a building or the like is flooded through the entrance / exit passage K increases, the entrance / exit passage K is closed in the following order.

  First, an oil supply pump is connected to the oil supply port 5a (see FIG. 4) via an oil supply pipe (not shown). Then, the oil supply pump is operated with the backflow prevention valve closed, and pressure oil is supplied to the hydraulic cylinder 6 a through the oil supply pipe and the oil supply pipe 4. As a result, as shown in FIG. 4, the ram 6 b moves forward, and the waterproof door body 2 rises from the upper surface of the pedestal portion 16 to a position where the lower end beam member 15 is separated.

  By closing the backflow prevention valve, even if the oil pump is stopped, the hydraulic oil is prevented from flowing in the direction opposite to the oil supply direction, so the hydraulic pressure in the hydraulic cylinder 6a is maintained at a high pressure state. Is done. Next, while maintaining the hydraulic pressure in the hydraulic cylinder 6a, the operator pulls the waterproof door body 2 toward the front side while maintaining the height of the waterproof door body 2 so that the waterproof door body 2 is closed (closed). The waterproof door body 2 is disposed at the fully closed position (see FIGS. 5 and 7). In a state where the waterproof door main body 2 is rotated to the fully closed position, the peripheral edge portion of the second outer plate 27 in the waterproof door main body 2 contacts the stepped portions DS1 and DS2 and the first door pocket side wall 20.

  Next, by opening the backflow prevention valve of the oil supply pump, the working oil flows in the direction opposite to the oil supply direction, and as a result, the ram 6b is moved backward as shown in FIG. The waterproof door body 2 is lowered to a height position where it abuts on the TG. In this state, since the weight of the waterproof door body 2 acts on the seal portion 17, the seal portion 17 is pressed against the floor surface TG. Thereby, the seal portion 17 and the floor surface TG are in close contact with each other, and the entrance / exit passage K is closed by the waterproof door 1. Therefore, even if the inside of the construction outside passage K2 (see FIG. 7) may be flooded, the inside of the construction inside passage K1 is prevented from being flooded.

  And when there is no possibility that the inside of a building etc. will be flooded, the waterproof door main body 2 is moved in the reverse order to the above.

  Specifically, first, the oil supply pump is operated with the backflow prevention valve closed, and pressure oil is supplied to the hydraulic cylinder 6 a through the oil supply pipe and the oil supply pipe 4. Accordingly, as shown in FIG. 5, the waterproof door body 2 is moved until the ram 6 b is advanced, the seal portion 17 is separated from the floor surface TG, and the lower end girder material 15 is positioned higher than the upper surface of the pedestal portion 16. To raise.

  Next, with the backflow prevention valve closed, an operator rotates the waterproof door body 2 to the right side wall TR side while maintaining the height of the waterproof door body 2 so that the waterproof door body 2 is It arrange | positions in a fully open position (refer FIG. 4).

  Next, by opening the backflow prevention valve, the ram 6b is retracted as shown in FIG. 3A, the seal portion 17 is separated from the floor surface TG, and the lower end girder 15 is the upper surface of the pedestal portion 16. The waterproof door main body 2 is lowered until it comes into contact with (see FIGS. 3A and 3B).

Therefore, even if the waterproof door body 2 rotates, the mutual positional relationship between the waterproof door body 2 and the hydraulic jack 6 does not change. As a result, when the waterproof door body 2 is rotated, The oil supply pipe 4 can follow the movement of the waterproof door body 2 without changing the shape. For this reason, it becomes unnecessary to give the second piping part 4a a large slack (play) as in the conventional case, and the length of the second piping part 4a can be set short. Thereby, while being able to improve the appearance of the 2nd piping part 4a, it can suppress that the 2nd piping part 4a is mischievous.

  Moreover, according to this embodiment, since the 2nd piping part 4a is linearly formed in the exterior of the waterproof door main body 2, and is metal, it can further improve the appearance of the 2nd piping part 4a, and 2nd It can suppress more effectively that the piping part 4a is mischievous.

  Further, according to this embodiment, the waterproof door body 2 is provided with the oil supply ports 5a and 5b, and the oil supply pipe 4 is connected to the oil supply ports 5a and 5b, so that a hydraulic pump is provided near the waterproof door 1 in an emergency. By bringing it in and connecting this hydraulic pump to the oil supply port 5a or the oil supply port 5b, it is possible to supply hydraulic pressure to the hydraulic jack 6. Therefore, it is possible to easily supply hydraulic pressure to the hydraulic jack 6.

  Moreover, according to this embodiment, the front-end | tip part of the ram 6b of the hydraulic jack 6 is supported by the jack support part 8 fixed to the 1st door pocket side wall 20, The driving force of the hydraulic jack 6 is supplied to the 1st door pocket side wall. Thus, the waterproof door body 2 can be lifted and lowered reliably.

  Further, according to the present embodiment, when the waterproof door body 2 is in the fully open position in the rotation direction, the pedestal portion 16 supports the waterproof door body 2 so that the seal portion 17 is separated from the floor surface TG. When the waterproof door main body 2 is in the fully open position, the waterproof door main body 2 is not separated from the floor TG without applying hydraulic pressure to the hydraulic jack 6 (while the hydraulic pressure is released). Can be arranged. Thereby, when the waterproof door main body 2 exists in a fully open position, it can prevent that hydraulic fluid leaks out from the hydraulic jack 6. FIG. Furthermore, when the waterproof door body 2 is in the fully open position, the seal portion 17 is strongly pressed against the floor surface TG, and the seal portion 17 can be prevented from being deformed and deteriorated by distortion.

  Moreover, according to this embodiment, since the base part 16 is arrange | positioned in the door front end side rather than the width direction center part of the waterproof door main body 2, the weight of the waterproof door main body 2 fully acts on the base part 16. FIG. Thereby, the weight load concerning the hinge part 14 is reduced.

  The embodiment described above can be modified as follows.

  For example, in the above embodiment, the oil supply pump is provided separately from the waterproof door 1 and connected to the oil supply port 5 when the oil supply pump is used. Instead, as shown in FIG. The oil pump P may be provided in the waterproof door body 2 in advance, and switches SW for operating and stopping the oil pump P may be provided on both surfaces of the waterproof door body 2. In this case, the entire hydraulic pressure supply path for supplying hydraulic pressure to the hydraulic jack 6 can be provided in the waterproof door body 2, and the entire hydraulic pressure supply path can be simplified.

  Moreover, in the said embodiment, although the waterproof door 1 is arrange | positioned in the middle part of the entrance / exit channel | path K, it may replace with this and the waterproof door 1 may be arrange | positioned in the outer side edge part of the entrance / exit channel | path K.

  Moreover, in the said embodiment, although the base part 16 is being fixed to the floor surface TG, it may replace with this and may be fixed to the 2nd door pocket side wall 19.

  Moreover, in the said embodiment, although the oil supply pump is connected to the oil supply port 5a, you may connect an oil supply pump to the oil supply port 5b.
