(Means for Solving the Problems) Hereinafter, an embodiment of this invention will be described with reference to the drawings. In a water area 1 at a boat race course, a net lifting device 2 is provided on the offshore side, and the net lifting device 2 is installed on the offshore side. A moving device 3 is provided, a net 4 is attached to the device 3, and the net 4 is normally submerged under the water surface on the offshore side, and the net 4 is floated to the water surface when necessary, and
It consists of something that is moved towards the shore to collect debris on the water surface.
尚、ネツト４は、水域を複数カ所に分け、それ
ぞれの箇所に分けて設けてもよい。 Note that the net 4 may be divided into a plurality of areas, and the net 4 may be provided separately at each area.
更に、昇降装置２の具体例は種々考えられる
が、その一例を述べると、岸側と沖側にそれぞれ
一対の支柱２ａ，２a′を設け、これらの各支柱に
は上・下方向に移動可能なリング２ｂが遊嵌され
ており、該岸側と該沖側の支柱に遊嵌されたリン
グ間にはそれぞれガイド棒２ｃおよびワイヤー２
ｄが固定されている。 Furthermore, various specific examples of the lifting device 2 can be considered, but to describe one example, a pair of columns 2a and 2a' are provided on the shore side and offshore side, respectively, and each of these columns is movable in the upward and downward directions. A guide rod 2c and a wire 2 are loosely fitted between the rings 2b that are loosely fitted to the shore-side and offshore-side supports, respectively.
d is fixed.
前記ガイド棒２ｃにはフロート２ｅが複数個設
けてあり、各フロートはそれぞれエヤーパイプ２
ｆで連通されて、一端は陸に設けた圧力タンクＡ
に連通され、該タンクよりエヤーを各フロートに
送ることにより浮上させ、逃がし弁を開くことに
より沈降させるものである。 A plurality of floats 2e are provided on the guide rod 2c, and each float is connected to the air pipe 2.
Pressure tank A is connected to F and one end is installed on land.
The floats are floated by sending air from the tank to each float, and allowed to sink by opening the relief valve.
そして、ワイヤー２ｄには動力或いは手動で移
動するネツト枠２ｇを設け、該枠２ｇにネツト４
を装着している。 The wire 2d is provided with a net frame 2g that can be moved by power or manually, and the net 4 is attached to the frame 2g.
is attached.
ネツト４は、ワイヤー、ガイド棒等の自重によ
り、通常時には水中の所定の位置に待機する。こ
れら昇降装置２は一個でもよく、水域が広い場合
には複数個に分けて隣接して設置してもよい。 The net 4 normally stands by at a predetermined position underwater due to the weight of the wire, guide rod, etc. These lifting devices 2 may be one piece, or if the water area is wide, they may be divided into a plurality of pieces and installed adjacent to each other.
また、ネツト昇降装置２の第二実施例を述べる
