JPS6024740Y2 - Underwater membrane to prevent sludge diffusion - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an underwater membrane for preventing sludge diffusion.

Conventionally, when a sheet is spread out underwater for the purpose of preventing sludge from spreading, etc., especially in the ocean, the sheet breaks and shellfish such as Fujitbo attach to its surface, and in severe cases, it becomes completely submerged. Many accidents occurred.

Methods such as applying chemicals to the sheet surface have been tried as a method to prevent Fujibbo etc. from adhering to the sheet, but although it is effective initially, the effect disappears after long-term use. There was a drawback.

As a result of various studies to solve these conventional drawbacks, the inventor of the present invention installed a net-like, sag-like, etc. underwater deposit removal member on both sides of the sheet, and sandwiched the upper end of the member between a pair of half-split floats. An underwater membrane for preventing sludge diffusion was completed by combining them and providing a weight at the lower end of the underwater deposit removing member.

Next, the present invention will be explained based on the accompanying drawings, but the present invention is not limited to the following explanation.

As shown in FIG. 1, the present invention provides underwater deposit removal members 2 having a net shape, a sag shape, etc. on both sides of a sheet 1, and is provided integrally with the sheet 1 at the upper end thereof. is provided with a weight 3 at its lower end.

As a means for integrating the sheet 1 and the underwater deposit removing member 2, the underwater deposit removing member 2 and the sheet are wound around a support pipe 4, for example, as shown in FIG.

As shown in FIG. 3, the underwater deposit removing member 2 and the support pipe 4 around which the sheet 1 is wrapped are sandwiched between a pair of hollow and sealed half floats 5, and A cup 6 having a hole through which the support pipe 4 passes is fitted to both ends of the float 5.

The support pipe 4 is fixed to the float by tightening both ends with screws or the like so that it does not fall off the float.

Furthermore, a connecting rod 7 is provided so as to pass through the support pipe 4 in order to connect the float 5 to which the sheet 1 and the underwater deposit removing member 2 are attached.

By providing connectors (not shown) at both ends of the connecting rod 7, a desired number of sludge diffusion prevention underwater membranes can be connected.

Further, as the underwater deposit removing member 2, a sag-like member as shown in FIG. 4 can also be used.

In the underwater membrane for preventing sludge diffusion according to the present invention, since the sheet 1 and the underwater deposit removal member 2 provided on its surface slide due to waves etc., the surface of the sheet 1 is constantly wiped, so that shellfish cannot adhere to it. is prevented.
