Description

[Detailed explanation of the idea] The present invention relates to a water intake device for underwater installation.

Conventionally, when dredging, reclamation, etc. were carried out, the reclaimed area was first surrounded by an embankment, etc., and a spillway was provided in this surrounding area, and the spillwater was discharged to the outside from the spillway. However, since the spillway in this construction method is fixed, as the reclamation progresses, a path is created for the spillwater to flow, resulting in a deterioration in the quality of the spillwater.

As a result of various studies to solve these drawbacks during dredging and reclamation, the inventor of the present invention has developed a device that can change the spill outlet to any desired location and can respond to fluctuations in water level. completed.

That is, in the present invention, a multi-stage cylindrical body consisting of an outer cylinder and a plurality of inner cylinders is configured to be expandable and retractable, and a float is attached at a spaced interval above the inner cylinder, which becomes the uppermost part when it is expanded. A sheet-like body is wound to cover the outer circumference from the inner cylinder, which is sometimes the topmost part, to the outer cylinder, and a drainage pipe is installed in the outer cylinder, and the length of the cylinder is forcibly adjusted. This is a water intake device for underwater installation, which is characterized by being equipped with a regulating device.

Next, a water intake device for underwater installation according to the present invention will be explained with reference to the drawings.

The water intake device for underwater installation according to the present invention is composed of a telescopic cylindrical body. This cylindrical body is composed of an outer cylinder 1 and a plurality of inner cylinders 2. Inner cylinder 2
are assembled into the outer cylinder 1 in order from the one with the largest inner diameter. Preferably, rollers 3 are provided at the bottom of each inner cylinder 2 to facilitate vertical movement.
Furthermore, on the upper part of the outer cylinder 1 and each inner cylinder 2, there is a locking part (not shown) at the position where the roller 3 rises in order to automatically pull up the next inner cylinder 2 when the inner cylinder 2 moves upward. will be established. It is preferable to provide a flange portion 4 on the upper edge of the inner cylinder 2. Furthermore, floats 5 are attached at intervals to the upper part of the inner cylinder 2, which becomes the uppermost part during expansion. By installing a plate-like body 6 on the upper surface of the float 5, it can be used as a workbench for operating a telescopic adjustment device 7, which will be described later.

The plate-like body 6 is further provided with a support frame 9 for mounting the chain block 8. On the other hand, the outer cylinder 1 is provided with a chain locking part 10. This locking portion 10 and chain block 8 are locked together by a chain 11.

In addition, in order to prevent or prevent water from flowing in from the outer cylinder 1 and the inner cylinder 2 or the space 12 between the inner cylinders 2 and 2, the outer circumferential part from the outer cylinder 1 to the inner cylinder 2, which is the topmost part when extended. The sheet-like body 13 is wound around. In addition, if necessary, in order to prevent the sheet-like body 13 from being pulled excessively when the inner cylinder 2 is expanded, the upper and lower ends of the sheet-like body 13 are connected with chains 14 having a length that allows the cylindrical body to extend to the maximum extent. Preferably, the knot prevents excessive stretching.

Further, a drain pipe 15 is provided at the bottom of the outer cylinder 1.

Next, a method of using the water intake device for underwater installation according to the present invention will be explained.

Install the water intake device for underwater installation at the desired water intake location. Since the water intake device installed in the water is provided with a float 5 at the top, it floats up and the inner cylinder 2 sequentially expands to form a cylindrical body. Surplus water is taken in from the space 16 between the floats and introduced into the cylindrical body. On the other hand, a drain pipe 15 provided in the outer cylinder 1 is connected to a water suction pump (not shown), and guides water inside the cylindrical body to the outside of the water device.

At this time, since the sheet-like body 13 is wound around the cylindrical body, if the sheet-like body is made of a water-impermeable material, water can be prevented from leaking from the interval portion 12 of the cylindrical body. Further, if the sheet-like body is a water-permeable cloth or the like, even if the water is passed through and taken from the spacer 12, the taken water is passed through the cloth, so the present invention can be preferably carried out. I can do it.

When it is desired to increase the amount of water taken from the interval 16 of the float 5, the chain block 8 of the telescopic adjustment device is used.
The purpose can be easily achieved by activating the system and forcibly submerging the uppermost inner cylinder 2 into the water.
