Description

[Detailed explanation of the idea] The present invention relates to a hose for a submersible pump.

Conventionally, to discharge sediment and mud from the bottom onto land, a submersible pump is moved using a ship or crane, but in this case the discharge hose is left appropriately slack and allowed to float freely in the water. put.

Therefore, there is a risk that the hose may be bent or tangled due to the movement of a ship or crane, the flow of water, etc.

Furthermore, when moving a submersible pump, the resistance of the water acts on the pump in addition to the total weight of the hose, making it extremely difficult to move the pump and hose. There was an inconvenience that the end of the hose could come off the discharge port of the pump due to the force.

The technical problem to be solved by the present invention is to prevent the hose from bending or tangling, and to allow the submersible pump to move smoothly.

The technical measures taken to solve the above technical problems are:
A floating body and a weight body are alternately connected to a hose to be connected to a submersible pump at appropriate intervals.

Since the hose floats in a meandering state due to the floating body and the weight body, free movement of the hose is restricted, and there is almost no possibility of the hose being bent or tangled.

Furthermore, since most of the weight of the hose is supported by the floating body, the submersible pump can be moved easily and smoothly.

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 shows a situation where the submersible pump 1 is positioned below the water surface 7 and near the riverbed 70.

The submersible pump 1 is suspended vertically downward from a crane, ship, etc. by a hanging rope 11, and the discharge port 1 of the pump 1
A discharge hose 3 of the present invention is installed between the pipe 2 on the land T1 and the discharge hose 3 on the land T1.
are connected.

The hose 3 is flexible, meandering up and down, and floating near the water surface 7 in a downwardly slack state.

A floating body 4 and a weight body 5 are disposed on the curved part on the water surface side of the hose 3, and weight bodies 5 are disposed on the curved part on the underwater side, respectively, and each floating body 4 and weight body 5 are connected to guide pipes 6 disposed at approximately equal intervals on the hose. are installed alternately.

The guide pipe 6 is formed by bending a metal pipe into an arched shape, and is attached by fitting the hose 3 into the inner hole of the pipe, and by moving the guide pipe 6 along the hose 3, the floating body 4 is attached.
, 4, the slack of the hose 3 can be set appropriately.

The floating body 4 is made of foamed material or other materials, and the volume of the floating body 4 is appropriately determined in consideration of the load of sand and soil passing through the weight body 5 and the hose 3.

The floating body 4 and the weight body 5 are attached to the guide tube 6 by appropriate means.

For example, as shown in FIG. 2, the floating body 4 has a T-shaped locking portion 8 at one end.
1. It is attached using the mounting bracket 8 which has a ring-shaped tightening part 82 on the other end, the locking part 81 is embedded in the floating body 4, and the fastener 82 is fitted onto the outer periphery of the guide tube 6 and screwed with screws 83 or the like. It is fastened.

Further, the weight body 5 is directly fixed to the curved protruding surface of the guide tube 6.

FIG. 3 shows another embodiment, in which the hose 3 is meandering in the water and floating in a downwardly sagging state, and the floating body 4 and the weight body 5 are attached to the vertically curved portion of the hose 3 with cables 9.9. Directly attached.

Note that if the curved portion has a bellows structure, bending of the hose 3 can be completely prevented.

However, the hose 3 is floating in a meandering state between the floating body 4 and the weight body 5, but there is a slack state of the hose 3 with an appropriate length between the adjacent floating bodies 4, 4. It is formed.

When the submersible pump 1 is moved in the direction opposite to the land as shown in FIG. 4, the slack in the hose 3 is stretched, and the floating body 40 closest to the pump 1 follows the movement of the pump 1.

Therefore, the pitch between the weight body 5a and the pump 1, the pitch between the weight body 5a and the pump 1,
There is a difference in pitch between the first weight body 5b and the next weight body 5b, and an imbalance (T1>T2) occurs in the forces TI and T2 acting on the weight body 5a, so the weight body 5a is moved toward the pump 1 side.

A similar action is performed sequentially over the entire length of the hose, and hose 3
stops moving when the pitches between the adjacent floating bodies 4, 4 respectively match and are balanced.

Therefore, the submersible pump 1 can be easily moved with a force sufficient to cause the floating body 4a closest to the submersible pump 1 to follow the submersible pump 1, and almost no unreasonable force acts between the pump 1 and the hose 3.

Similarly, when the pump 1 is moved in the direction of the land 71, the floating bodies 4 and the weight body 5 are sequentially moved from the pump 1 side toward the land T1 until a balanced state is reached where the pitches between the adjacent floating bodies 4 and 4 match. It can be moved.

As described above, in the present invention, the floating bodies 4 and the weight bodies 5 are arranged alternately on the flexible hose 3, and the hose 3 is suspended in the water in a vertical meandering state, so that the free movement of the hose 3 is restricted. Therefore, there is almost no possibility that the hose 3 will break or come to an end.

Furthermore, since the hose 3 is slackened downward between the floating bodies 4 and 4, the submersible pump 1 can be easily moved, and the hose 3 sequentially follows the movement of the pump 1 from the pump 1 side.

Therefore, since no excessive force is applied between the pump 1 and the hose 3, there is no risk that the end of the hose 3 will come off the discharge port 10 of the pump 1, and the discharge operation can be performed extremely smoothly, which is excellent in practical terms. It is effective.
