DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for forcibly pumping irrigation water to a paddy field from a river by a pump, and more particularly, to protecting pumps from damage from sediment and driftwood in a flood or the like. The present invention relates to a structure of a movable pumping device capable of performing the above-mentioned steps.

[0002]

2. Description of the Related Art Conventionally, a pumping apparatus as shown in FIGS. 6 and 7 has been used. With reference to FIG.
Is installed on the riverbank on land, and pipes 2
2 is placed in water and the water is pumped up. The pumpable height was about 7 meters under 1 atm. Therefore, the maximum level at which the pump 21 can be installed is about 7 meters from the normal water level. -Although the height of the river is high, the rise in river water level during the recent floods has an abnormal tendency, far exceeding 7 meters and 1
It is not unusual to reach four meters. This is due to the deforestation and land clearing due to the development of large recreational facilities.
The water level of rivers rises rapidly even with relatively small amounts of rainfall, which has not been experienced before, due to the conversion of land to concrete due to land development, development of residential land, increase of untreated wind-down trees, and delay of river dredging work. However, it causes serious damage to conventional pumping equipment for irrigation. In the case shown in FIG. 6, the pump hut 23 spills out of the pump hut 23, or the pump hut 23 is buried in the earth and sand even if the outflow of the pump hut 23 is removed. Clogged, unusable,
There was a drawback that enormous cost and labor were required for the restoration. Such disasters occur in rural areas where the population is aging and the number of young workers is drastically decreasing. Was eagerly awaited.

In FIG. 7, since the water is pumped by the submersible pump 24, the pump hut does not flow out or is buried as in the case of FIG.
Since the pipes 4 and the pipes 26 are buried in the earth and sand, they cannot be used, and as in the case of FIG. The main cause of this is shown in FIG.
Also, the conventional apparatus shown in FIG. 7 is of a fixed type, and once installed, cannot be moved. Therefore, there is no other way but to withstand flood damage at the place.

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, and is a movable type capable of easily lifting pumps to land when the water level of a typhoon rises. The purpose is to provide a water pumping device.

[0005]

According to the movable pumping device of the present invention, a plurality of elements are rotatably connected to each other, and a support which is linearly stationary when the plurality of elements are extended is arranged along the river bank. The uppermost element of the support is rotatably supported by a structure installed at the upper end of the river bank, and a submersible pump is attached to the lowermost element of the support, A guide structure, which is located on the same vertical plane as the support and is inclined upward, is installed on the rear land portion, and a chain or rope is connected to the support via the guide structure. And is fixed to a submersible pump attached to the tip of the support.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, as shown in FIG. 1, when a plurality of elements 1 are rotatably connected and extended,
A support 2 that is stationary in a straight line is disposed along the riverbank 3, and the uppermost element 1 a of the support 2 is rotatable with respect to the structure 4 installed at the upper end of the riverbank 3. A submersible pump 5 is mounted on the lowermost element 1b of the support 2 and a guide structure located on the same vertical plane as the support 2 and inclined upward on the land portion 6 behind the structure 4. 7, a chain or rope 8 is extended along the support 2 via the guide structure 6, and is fixed to the submersible pump 5 attached to the tip of the support 2.

As shown in FIG. 1, the upper end of the chain or the rope 8 is, for example, a winding or rewinding device for the chain or the rope 8 installed at the rear end of the guide structure 7. 9. As shown in FIG. 2, the element 1 includes, for example, a shelf 10 on which a chain or a rope 8 is placed, a rubber hose (not shown) connected to the submersible pump 5, and electric wires for supplying power to the submersible pump 5. (Not shown) such as a metal box-shaped body having a space portion 11 to house therein, and has a hole 12 for connecting with an adjacent element 1 on a front side surface and a rear side surface, so that the connection portion is smooth. The plate 13 is fixed to the bottom of the rear end so that the connected element 1 can be stopped in a straight line when the connected element 1 is extended so that the front end can be bent. FIG. 3 is a side view when the connected element 1 is extended, and the plate 13 serves as a stopper so that the connected element 1 can be stopped in a straight line.

At the time of normal water intake, the positional relationship between the support 2, the submersible pump 5, and the like is as shown in FIG. When the submersible pump 5 is to be lifted to the shore at the time of rising water due to a typhoon or the like, first, the winding / rewinding device 9 is operated manually or electrically, and the chain or the rope 8 is wound. Element 1b to which pump 5 is attached
However, as shown in FIG. 4 (a), it is bent and inverted upward, and while riding on another element 1 in which the submersible pump 5 and the element 1b are adjacently connected, FIG. 4 (b)
As shown in FIG. 5, the submersible pump 5 moves upward, and eventually is lifted up to the upper end of the guide structure 7, as shown in FIG. Reference numeral 14 denotes a guide roller mounted on the upper portion of the guide structure 4.

Next, in order to return the submersible pump 5 to the water of the river from the state shown in FIG. 5, the winding / rewinding device 9 is operated manually or electrically to rewind the chain or the rope 8. And the support 2 is moved by the weight of the submersible pump 5
Is refracted and reversed in the opposite direction to that described above, and finally, as shown in FIG. 1, the support 2 is stopped in a linear state, and the submersible pump 5 is submerged. Can be set to the normal position.

[0010]

The present invention is configured as described above.
The following effects are exhibited. Since the submersible pump can be moved to a safe place at the time of increasing water, it is not buried in earth and sand or flows out as in the conventional case. Therefore, enormous cost and labor as in the related art are not required for restoration. The submersible pump can be moved easily, and maintenance and inspection on land is possible. As a result, maintenance and inspection can be sufficiently performed, stable operation without trouble can be performed, and the life of the submersible pump can be extended. Since the structure is simple, it can be installed inexpensively and the equipment cost can be reduced.
