DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle dropping device with a pump provided in an inflow channel or a discharge channel.

[0002]

2. Description of the Related Art Conventionally, when conducting inspection and maintenance of drainage pump equipment, removal of sand accumulated in an inflow channel, and maintenance of inflow and discharge channels, vertical guide grooves provided on both side walls of the channel. It is practiced to cut off a water channel by dropping a corner into the water channel to remove water in the water channel.

[0003] As a method of eliminating water in a water channel, conventionally,
A drain pump was put into the cut off channel and a drain pipe was attached, and then the drain pump was operated, thereby draining the water in the cut off channel over the corner drop.

However, for safety during drainage, the drainage pipe must be fixed so that the drainage pipe does not move during the operation of the pump, which makes the on-site work complicated, improves work safety and improves work efficiency. Could not be planned.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and has as its object to simplify the work on site, improve the safety of work, and improve the work efficiency. To provide facilities.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a corner-dropping facility for cutting off a waterway by dropping a corner into a waterway, and incorporating a drainage pump mechanism into the cornerdrop itself. . The drain pump mechanism has a drain pump, a discharge channel, and a discharge port. In the case of a single corner drop, a drain pump and a discharge port of the drain pump are provided in one corner drop. In the case where the angle drop has a plurality of stages, a drainage pump is incorporated in one of the angle cuts, and a discharge port of the drainage pump is provided in any other angle drop. In other words, if the angle drop is two-stage, a drainage pump is installed in the first-stage angle drop.
The outlet of the drainage pump will be provided at the corner of the step. If the angle drop is three or more, a drainage pump is incorporated in the lower angle drop, a discharge channel of the drainage pump is provided in the middle angle drop, and a discharge port of the drainage pump is provided in the upper angle drop. Further, a suction pipe extending to a position away from the drain pump may be attached to the drain pump.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a view showing an embodiment of the present invention. FIG. 1 (a) is a plan view of a main part showing a state where a corner dropping facility 2 is dropped into a water channel 1, and FIG. FIG. 1C is a front view, and FIG. 1C is a sectional view taken along line AA of FIG.

As shown in FIG. 1, the corner dropping equipment 2 has three corner droppings 3, 4, 5 provided in grooves 17, 17 provided in parallel in the vertical direction at opposing positions on both side wall surfaces of the water channel 1. It is constructed by dropping it in an overlapping manner. The three corner droppings 3, 4 and 5 constitute the corner dropping equipment 2. Hereinafter, each component will be described.

A drain pump 6 is incorporated in the lowermost corner drop 3, and a water inlet 19 is opened on the side wall surface on the lower side to be drained. The drainage pump 6 is provided with an upwardly directed discharge passage 7 connected thereto. The opening at the upper end of the discharge channel 7
Is located at the center of the upper end face.

A discharge channel 8 is provided in the corner drop 4 at the intermediate stage. The discharge passage 8 is provided so as to connect the center of the upper end surface of the corner drop 4 to the center of the lower end surface.

The uppermost corner drop 5 is provided with a discharge channel 9 extending upward from the center of the lower end face thereof, and a discharge port 10 connected to the upper end of the discharge channel 9. The discharge port 10 is
It is open toward the side wall surface opposite to the water suction port 19.

A corner-dropping packing 11 is attached to the mating surfaces of the corner-droppings 3, 4 and 5 in each step so as to surround the mating surfaces.

A discharge channel packing 12 is mounted around the mating surface between the discharge channel 7 and the discharge channel 8 and around the mating surface between the discharge channel 8 and the discharge channel 9.

FIG.
As shown in FIG. As a result, the discharge channels 7, 8, and 9 are connected to form one discharge channel.

Then, when the operation of the drain pump 6 is started,
The water in the water channel 1 on the side to be cut off and drained is drained from the water inlet 19 through the discharge passages 7, 8, 9 through the discharge port 10.

As described above, according to the present invention, the drainage pump 6, the discharge passages 7, 8, 9 and the discharge port 10 are angled down.
Since it is built in 5, the droppings 3, 4, 5 are simply dropped into the grooves 17, 17 of the waterway, and the drainage pump 6 can be operated immediately without additional work such as putting in a drainage pump or attaching pipes. Can be started.

In the above-described embodiment, the three-step angle drop 3,
The corner dropping equipment 2 is constituted by 4 and 5, but when it is constituted by two stages, the angle dropping 4 in the intermediate stage may be omitted, and 4
In the case of a configuration having more than one step, the middle step 4 may be formed as a plurality of steps. In the case of a one-stage configuration, the drain pump 6 and the discharge port 10 may be built in one corner drop.

In the above embodiment, the discharge channel 9 and the discharge port 10 are provided in the uppermost corner drop 5, but the discharge channel 9 may be omitted and only the discharge port 10 may be provided.

As shown in FIG. 2, when the water in the water channel 1 having the step-down portion 21 is drained using the corner dropping device 2 according to the above embodiment, the water in the step-down portion 21 cannot be drained. In addition, 23 is a pump of the drainage pump equipment installed in the step-down part 21 part.

In such a case, as shown in FIG. 3, a suction pipe 25 extending away from the drain pump 6 is attached to the water suction port 19 of the drain pump 6 provided in the corner drop 3, and the suction pipe 25 is provided. What is necessary is just to comprise so that the front-end | tip of the pipe | tube 25 may be inserted in the step part 21. FIG. With this configuration,
The water in the step portion 21 can also be easily drained. The suction pipe 25 may be attached in advance before the corner drop 3 is put into the water channel 1, or may be connected after draining until water remains only in the step-down portion 21 as shown in FIG. .

[0021]

As described in detail above, the present invention has the following excellent effects. Since the drain pump mechanism consisting of a drain pump and a discharge port is incorporated in the square drop itself, simply dropping the square drop into the ditch of the waterway will allow the drain pump to be installed immediately without separate drain pump installation work or pipe installation work. Operation can be started, work on site is simplified, safe and quick.

[0022] Even if the corner cutting equipment is constructed by dropping a plurality of corner cuts so as to overlap the water channel, a drainage pump is incorporated in one of the plurality of corner cuts and any other corner drop is installed. In addition, by providing a discharge port of the drainage pump and providing a discharge channel in the case where there is a corner drop in the middle stage, it is possible to easily cope with this.

When a suction pipe extending to a position away from the drain pump is attached to the drain pump, even if there is a stepped portion in the water channel to be drained, it is easy to drain water to the water therein. it can.
