Abstract

<P>PROBLEM TO BE SOLVED: To provide a cover structure for a water storage facility, which is formed by supporting sheets on a water surface by means of buoyancy bodies floating on the water surface, continuously floating cover blocks by the support of the buoyancy bodies, and attaching deadweights to the buoyancy bodies at end areas of the facility, to thereby stabilize the cover structure due to hanging of the deadweights in water. <P>SOLUTION: According to the cover structure for the water storage facility, the sheet material 1 having predetermined longitudinal and transverse dimensions, has the buoyancy body 2 arranged at least on one width side along the entire width, and further has a contact piece 3 having a predetermined length arranged along a peripheral portion thereof, to thereby form the cover block 5. Then the cover blocks 5 thus formed are successively connected together via their contact pieces 3, and floated on the water surface. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a covering structure in a water storage facility such as agricultural water or industrial water.

In the water storage facility, the top surface is covered with a canopy to prevent water pollution caused by fallen leaves and dust, as well as the generation of seaweed and other algae, and to prevent water from evaporating and to prevent clogging of water intake and watering equipment. It is done to cover with.
As a conventional technique of such a canopy, there is a technique of combining a synthetic resin floating body placed on the water surface and a synthetic resin sheet placed on the upper surface of the floating body (see, for example, Patent Document 1). ).
JP 2001-19087 A

However, in the above-described conventional technology, the synthetic resin sheet has a structure that covers not only the water surface but also the inner periphery of the water tank, so a sheet having a large area is required, and the upper end of the water tank is used. There is a problem that requires installation to be installed around.
Furthermore, during normal times, the synthetic resin sheet covering the inner surface of the water storage facility is fluttered under the influence of wind, and there is a problem that countermeasures are required.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to directly cover and cover a sheet with a sheet.

  Therefore, the present invention provides a buoyant body having a length in the width direction on at least one side of a sheet material set to a predetermined length and width, and a connection piece having a predetermined length is provided around the sheet material to cover the sheet material. A block is formed, and the covering block is continuously floated through the connection piece.

Thereby, the present invention can support the sheet on the water surface by a buoyancy body floating on the water surface, thereby allowing the covering block to be continuously floated, and by attaching a weight to the buoyancy body at the end, A stable coating structure can be obtained by dropping a weight in water.
Furthermore, since the covering structure is configured by connecting the block bodies, construction is easy and partial replacement is possible, and an effect that a durable covering structure can be constructed is obtained.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory view showing an embodiment.
In the figure, reference numeral 1 denotes a sheet material made of rubber or synthetic resin, which is provided with a long buoyant body 2 having a predetermined length in both the vertical and horizontal directions and having a length over the entire length of the width on one side thereof. .
A connection piece 3 having a predetermined length made of a material similar to or similar to the sheet material is provided around the sheet material 1, and a connection portion 4 is provided on the connection piece 3. In addition, this connection piece 3 is a concept including what used the edge part of said sheet | seat material 1 as it is. The length may be set arbitrarily.

The connecting portion 4 is, for example, a fastener or a hook-and-loop fastener as shown in FIG. 2, a structure of a locking hole that is connected by a rope or the like as shown in FIG. Any structure may be used as long as it can be easily operated and is durable.
The covering block 5 is configured as described above. As described above, the covering block 5 is not necessarily a unit in which the buoyant body 2 is attached to a single sheet material 1, and two or more such units may be continuous to form one block.

The buoyancy body 2 is made of a material having a lower specific gravity than water, such as a foamed resin body such as foamed polystyrene, or a balloon body made of rubber or a synthetic resin, or a structure that floats on water. Any cross section may be used, and the cross-sectional shape is not limited to a circle. For example, a flat circle such as that shown in FIG. 3 may be used.
Reference numeral 6 denotes a hanging body attached to the buoyancy body 1 to hang down in water, such as a curtain or body made of rubber or synthetic resin, and a weight 7 attached to the lower end. A similar connection portion 4 that can be connected to the connection portion 4 is provided at the upper end of the hanging body 6.

Further, if necessary, as shown in FIG. 4, the connection piece 4 is provided with double connection portions 4, the upper connection portion is used for connecting the covering blocks, and the lower weight body 6 is connected to the lower connection portion. The lower weight body may be attached to any continuous covering block so as to be connected.
As shown in FIG. 6, the entire surface of the water storage facility can be covered by suspending the covering blocks thus arranged in a row in the vertical and horizontal directions. At this time, by connecting the respective coating block side portions of the coating block rows connected in the vertical direction (or the horizontal direction) via the connecting portion 4 by the above-mentioned connecting means or the like, the horizontal direction (or the vertical direction) To cover the entire surface of the water storage facility.

As shown in FIG. 4, the covering blocks covering the water surface in this way are arranged at predetermined intervals with one end around the water storage facility, as shown in FIG. It is locked by the attached mooring line 8.
Further, as shown in FIG. 5, the sheet body may be a floating material that is heavier than water and is immersed in water.

  In the above description, the case where the buoyancy body is attached only in one direction of the horizontal (vertical) direction has been described. However, the buoyancy body is attached also in the direction orthogonal to the attachment direction, and the covering block is made continuous. The buoyancy body may be arranged in both the vertical and horizontal directions.
