2. Description of the Related Art In the event of a flood, an integrated pump is installed at the boundary between a tributary and a river in order to prevent the water of the river from flowing back to the tributary side and to drain the inland water from the tributary side to the river. As the gate equipment, those shown in FIGS. 3 and 4 are known. The pump integrated gate equipment is configured as follows. That is, the door body 1 is incorporated in the guide 2 so as to be able to move up and down, and is connected to the door body lifting / lowering means 4 via the suspension spindles 3. By activating the door body lifting / lowering means 4 manually or automatically in the forward or reverse direction, the spindles 3 and 3 and the door body 1 are moved up and down by a predetermined stroke to open and close the gate. On the other hand, a drain column 5 is built in the door 1, and a pump 6 is installed at the bottom of the drain column 5.

[0003] In the pump-integrated gate equipment constructed as described above, the door body 1 is activated by activation of the door body lifting / lowering means 4.

The structure is such that the impeller 6B is fixed. In the figure, reference numeral 8 denotes a cabtire cable for supplying power to the pump drive source 6D.

[0005] In the pump-integrated gate equipment, a large-capacity pump 6 is installed to increase the drainage capacity, and the large-capacity pump 6 is operated by a large-capacity large-sized pump driving source 6D. In the conventional pump 6, the pump drive source 6D is supported by the suction cover 6A via the guide blades 6C, 6C. Therefore, if a large pump drive source 6D is used to increase the drainage capacity, the pump cover 6A The outer diameter of the guide blades 6C, 6C is increased, the pump 6 itself is enlarged, and the drainage column 5, the door 1, and the like are enlarged.

[0006]

That is, in the conventional pump-integrated gate equipment, if a large pump drive source is used to increase the drainage capacity, the pump itself becomes large and the pump-integrated gate equipment becomes large. There is a problem that the initial cost is increased due to the increase in the initial cost. Therefore, the present invention can suppress the increase in the size of the pump itself even if a large pump drive source is used to increase the drainage capacity, and can avoid the increase in size of the pump integrated gate equipment and high initial cost. It aims to provide a pump integrated gate facility that can.

[0007]

In order to achieve the above object, according to the present invention, a door body incorporated in a guide so as to be able to ascend and descend is connected to a door body elevating means via a suspension member, and the door body is lifted and lowered. With the activation of the means, the hanging member and the door body move up and down to open and close the gate, and a pump is installed in a drainage column built in the door body, and the pump is operated by operating the pump in the closed state of the door body. -In a pump-integrated gate facility configured to drain internal water on the upstream side into a river on the downstream side, at least a suction cover, a pump having an impeller and guide blades are installed at a lower portion of the drainage column. And a pump drive source is provided above the drainage column, and the pump drive source and the impeller are connected to each other via a main shaft.
According to the present invention, the pump drive source is a suction cover, an impeller,
Since it is installed on the upper part of the drainage column away from guide vanes, etc., even if a large pump drive source is used to increase the drainage capacity, this large pump drive source It does not affect the outer diameter. Therefore, the size of the pump itself can be suppressed, and the drainage capacity can be increased without increasing the size of the drainage column and door.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a vertical sectional side view of FIG. 1, and the same or corresponding parts as those of the conventional example of FIG. 3 and FIG. I do. 1 and 2, a door 1 is incorporated into a guide 2 so as to be able to move up and down, and
Is connected to the door body lifting / lowering means 4. By activating the door body lifting / lowering means 4 manually or automatically in the forward or reverse direction, the spindles 3 and 3 and the door body 1 are moved up and down by a predetermined stroke to open and close the gate. on the other hand,
A pair of drainage columns 5 and 5 are built in the door 1, and a pump 6 is installed at the bottom of each of the drainage columns 5 and 5.

Each pump 6 includes a suction cover 6A, an impeller 6B and a plurality of guide blades 6C, 6C. A pump drive source 6D composed of an electric motor includes a drain column 5,
