Description

  The present invention relates to a strut adhering matter removing apparatus that removes adhering matter adhering to a strut supporting a laver net from the strut.

  A laver net used for laver culture is stretched between a large number of pillars arranged at predetermined intervals in an upright state from the sea floor to the sea, and is located near the sea surface for laver culture. The support for the laver net is inserted into the seabed at a predetermined depth to be in an upright state, but a portion of the support in the sea tends to be in a state where marine organisms and plants such as shells and barnacles are attached.

  The support is pulled out of the seabed and lifted from the sea and stored on land, etc., except during the seaweed cultivation season, but if this deposit is left on the support as it is, handling becomes worse due to weight increase etc. In addition, since the occupied space per column also increases, it is necessary to store after removing the deposits attached to the column before storage. The removal of such deposits is often performed on a ship that recovers the props from the sea because it is convenient to return the deposits to the sea from the viewpoint of environmental protection and the cost of waste disposal.

In order to remove a large amount of deposits efficiently when removing the deposits from the support for the laver net, a mechanical removal device has been used. One such example is described in Japanese Patent No. 3884062.
Japanese Patent No. 3884062

  Such a conventional apparatus for removing deposits is as shown in the above-mentioned patent document, and can be attached to a ship that recovers a column from the sea, and the deposit can be quickly removed from the column pulled up from the sea. The removal process can be performed, and the deposit was brought into contact with the rotating part for removal, and the deposit was scraped off and removed from the column. Since the removal is carried out by pressing the shards, the removed debris is likely to be scattered around, and it is dangerous for the shards to hit the operator, and the debris is scattered in the surrounding environment such as on the ship. Had the problem of reaching.

  In addition, the vibration that occurs with the rotation of the rotating part that rotates in a cantilevered state is transmitted to the hull where the device is installed, but in the case of a relatively small ship for nori culture, this vibration causes In addition to being in a state of hindering various operations, vibration is directly transmitted to the operator through the support column, and there is a problem that it is difficult to perform the removal operation while holding the support column.
